LOW INSERTION FORCE CONNECTOR ASSEMBLY AND SEMICONDUCTOR COMPONENT TEST APPARATUS

Description

TECHNICAL FIELD

The present invention relates to a low insertion force connector assembly and a semiconductor component test apparatus, and more particularly, to a low insertion force connector assembly and a semiconductor component test apparatus that are capable of achieving rigid and simple coupling between a first connector and a second connector and stable contacts between connector pins and contact pins.

BACKGROUND ART

So as to allow a connector and a connection component mounted onto the connector to be electrically connected to each other reliably, connector pins of the connector and electrical terminals of the connection component have to be pressurized against each other. If the pressurizing forces are strong, electrical contacts become increased, but frictional forces are also big, so that it is hard to insert or separate the connection component into or from the connector. If a plurality of pins is mounted on the connector or if connection components are inserted simultaneously into a plurality of connectors, especially, a relatively large force has to be applied to insert the connection components into the plurality of connectors. So as to solve the above-mentioned problem, there is suggested a zero insertion force (ZIF) connector that does not need any force at the time when a connection component is inserted thereinto and pressurizes connector pins against the connection component after the insertion of the connection component.

A semiconductor test apparatus used to test fine semiconductors needs high reliability in operation. So as to reliably test the semiconductors at a high speed, the connector used in the test apparatus should be reliably coupled with the connection component.

As shown in FIGS. 1 to 5, a first connector 1 of the conventional connector assembly has a rectangular parallelepiped-shaped housing 2 having concave portions 4, contact assemblies 6 disposed in the concave portions 4, driving shafts 8 for driving the contact assemblies 6, a lever 10 connected to the driving shafts 8, and cover members 12 for protecting and keeping the contact assemblies 6 in the concave portions 4. Two rectangular openings 16 are formed in parallel with each other with respect to a bottom wall 14 (See FIG. 4) of the housing 2 along a longitudinal direction of the housing 2. Flanges 40 (See FIG. 4) protrude inward from the inner edges of each opening 16. Support walls 17 are formed integrally with both end portions of the openings 16 in such a manner as to have a height of about ½ of a height of the housing 2. A separation wall 18 for connecting the two support walls 17 is formed integrally with the bottom wall 14 between the openings 16.

The contact assemblies 6 are configured to have different two kinds of contacts 28 and 30 protected and kept in insulating base members 26 made of a resin by means of insert molding. The contacts 28 and 30 have respective bodies 34 and dynes 32 extended downward from the bodies 34 in such a manner as to be attached to a substrate (not shown). The bodies 34 are expanded to the outside. The base members 26 are attached to the openings 16 of the housing 2 by means of press-fitting.

The front ends of the curved bodies 34 of the contacts 28 and 30 of the contact assemblies 6 are accommodatedly oriented inward and are then extended linearly to form contact portions 36. The front ends of the contact portions 36 are bent more inward to form bent locking end portions 38. As the base members 26 are disposed in the openings 16, the contact assemblies 6 are attached to the housing 2.

The driving shafts 8 are molded with a metal material like stainless steel, and two driving shafts 8 corresponding to two pairs of contact rows are provided, so that the two driving shafts 8 are disposed between the two rows of the contacts 28 and 30. A body 7 formed on each driving shaft 8 by means of insert molding has a sectional shape of a conical cam.

The cover members 12 have rectangular shapes and include two rows of keeping portions 60 extended in long directions thereof on edge surfaces 62 thereof in such a manner as to correspond to the rows of contacts 28 and 30. The keeping portions 60 protrude from the edge surfaces 62 in such a manner as to be formed unitarily with the cover members 12. As most shown in FIG. 6, slots 64 extended in up and down directions are formed on both sides of the keeping portions 60 at the positions corresponding to the contact portions 36 of the contacts 28 and 30 along the long directions of the keeping portions 60. The contact portions 36 of the contacts 28 and 30 come into contact with the slots 64, so that they can come into contact with the electrical terminals.

Spaces 68 are formed inside each keeping portion 60 by dividing an interior of the keeping portion 60 through an isolation wall 66. Concave locking portions 70 are formed on the upper portions of the spaces 68, that is, around a flat surface 61 of the keeping portion 60. Holes 72 are penetrated into transverse centers of the cover members 12 on both ends of the keeping portions 60. Thin and long rectangular openings 74 are formed on both transverse sides of the cover members 12 in such a manner as to be adjacent to the holes 72. Cams 44 are disposed in the openings 74. Openings 80 are formed over the transverse directions of the cover members 12 around both ends of the cover members 12 on the outsides of the openings 74, and key type members 48 are disposed in the openings 80. Both ends of the cover members 12 are connected by means of connection portions 82. A curved concave portion 86 for accommodating the end of the driving shaft 8 connected to the lever 10 is formed on an end wall 84 of one side connector 82.

So as to attach the cover members 12 to the housing 2, the cover members 12 are disposed in the concave portions 4 of the housing 2, and after bolts 13 are inserted into the holes 72, next, they are fixedly coupled to nuts 23 of the housing 2. After that, the driving shafts 8 are rotatably supported in the housing 2. Further, the lever 10 protrudes outward from an incised portion 5 of the housing 2, so that it is possible to operate the lever 10 at the outside of the housing 2.

As shown in FIGS. 5 and 6, the conventional second connector 100 has a thin and long rectangular housing 102 and contacts 104. The second connector 100 has end portions 108 formed on both ends of a fitting portion 106 to the first connector 1 in such a manner as to have complementary shapes with the connection portions 82. Protrusions 112 protrude outward from outside sections 110 of the end portions 108 in the long direction of the housing 102 in such a manner as to correspond to the two driving shafts 8. Dynes 114 of the contacts 104 protrude downward from the second connector 100. The fitting portion 106 has two fitting concave portions 116 formed therein in parallel with each other in such a manner as to correspond to the keeping portions 60 to accommodate the keeping portions 60 therein.

As shown in FIGS. 7 to 9, the long diameters of bodies 7 of the contacts 28 and 30 are in longitudinal directions in a state just before the second connector 100 and the first connector 1 are completely fitted to each other, so that the contacts 28 and 30 are in displaced states to the most inner side. Accordingly, the contact portions 36 of the contacts 28 and 30 are not moved to the outsides of the slots 64, but they are located within the slots 64. On the other hand, front end contact portions 126 of the second connector 100 come into slight contact with the contact portions 36 of the contacts 28 and 30, and accordingly, they are in a low contact pressure. The base members 27 have ribs 27a formed on the lower ends of both sides thereof in such a manner as to be extended to the long directions thereof, and the ribs 27a are attachedly connected to the lower ends of the end portions 19a of the openings 19 of the housing 2.

If the lever 10 is rotated by about 90°, it is cooperatively operated with the driving shafts 8 so that the cams 44 are rotated in the opposite directions to each other. Stopping portions 44a of the cams 44 coming contact with fitted surfaces 122 are separated from the fitted surfaces 122 and are moved in transverse directions within rear grooves 20. That is, the second connector 100 is in a complete fitting position. If the bodies 7 of the driving shafts 8 are rotated by about 90°, the long diameters thereof are moved in the transverse directions to pressurize the bodies 34 of the contacts 28 and 30 outward. Accordingly, the contact portions 36 of the contacts 28 and 30 are displaced to the outsides and moved toward the contacts 104 of the second connector 100 so that they come into contact with the contacts 104. As a result, the contacts 104 and the contacts 28 and 30 are electrically connected to each other.

However, the coupled state between the conventional connectors is dependent upon a frictional engagement force. Accordingly, the contacted states of the contacts may be poor or the coupled state between the connectors may be released according to external forces applied to the connectors.

As the number of contacts of the connectors is increased, further, an insertion force needed for coupling the connectors becomes large and the coupling process becomes also difficult.

A semiconductor component test apparatus used to test a semiconductor component requires very high reliability electrically or positionally. To rapidly and reliably test the semiconductor component, a connector used for the test apparatus should come into contact with a connection component reliably.

FIG. 30 is a sectional view showing a conventional semiconductor component test apparatus for texting electrical properties of semiconductor components. As shown in FIG. 30, the conventional semiconductor component test apparatus includes a contactor 20 coming into contact with a semiconductor component 10, a substrate 30 for supplying electrical signals to the contactor 20, a plurality of connection components 40 fixed to the substrate 30, a plurality of connectors 50 detachably connected to the plurality of connection components 40, a connector stand 90 for fixing the plurality of connectors 50, and a holder 80 for supporting the plurality of connectors 50 and the connector stand 90.

Generally, the substrate 30 and the connector stand 90 have a round shape, and the plurality of connection components 40, the plurality of connectors 50, and a plurality of fixing members 86 like bolts are disposed radially from the centers of the substrate 30 and the connector stand 90. Relative positions of the substrate 30 and the holder 80 are fixed, and even if a force in a vertical direction is applied between the connection components 40 and the connectors 50, accordingly, relative position relations between the connection components 40 and the connectors 50 are maintained.

FIG. 31 is a perspective view showing the connectors of the semiconductor component test apparatus of FIG. 30, and FIG. 32 is an enlarged view showing a portion of the connectors of FIG. 31. Each connector 50 has two handles 52 attached to the outside thereof to rotate a cam 52a disposed therein. Also, the connectors 50 have guides 2 located on the outside over the handles 52 to drive the handles 2 and a handle driver 4 for rotating the guides 2. As the handle driver 4 is driven in a state where the connection components 40 are inserted into the connectors 50, the guides 2 and the handles 52 are moved to allow the connectors 50 to be connected to the connection components 40. Accordingly, the connectors 50 are connected simultaneously to the connection components 40. The guides 2 are attached to the inner surfaces of the handles 52. So as to allow the guides 2 to be gently rotated with respect to the connectors 50, pulleys 6 are disposed between the connector stand 90 and the guides 2.

FIG. 33 is a sectional view taken along the line A-A of FIG. 32 so as to explain the connector 50.

As shown in FIG. 33, the connector 50 includes a connector body 51 made of a synthetic resin to have a shape of a hollow body open in an up and down direction, upper supports 55 disposed on top openings of the connector body 51, lower support members 57 disposed on bottom openings of the connector body 51, cams 52a rotatably disposed in the connector body 51 in such a manner as to be connected to the handles 52, and a plurality of connector pins 53 arranged in a longitudinal direction of the connector body 51 in such a manner as to be located on both sides of the cams 52a.

If the upper supports 55 are disposed on the top openings of the connector body 51, upward open concave grooves are formed on the top of the connector 50.

The upper supports 55 have downward open portions formed on the lower portions thereof and protrude upward to form side open portions communicating with the downward open portions on the left and right sides of the protruding portion thereof. The lower portions of the connector pins 53 are inserted into the upper supports 55, and the upper portions thereof are located on the side open portions of the upper supports 55. The connector pins 53 are extended downward to pass through the cams 52a and the lower support members 57, so that the end portions thereof protrude downward from the connector body 51 and are then connected to a test board (not shown).

The upper supports 55 have the lower open portions spaced apart from each other to the left and right sides and the protruding portions protruding from the tops of the lower open portions. The cams 52a are located on the lower portions of the lower open portions of the upper supports 55. The connector pins 53 are located on both sides of each cam 52a, and they are pressurized against the cam 52a.

FIG. 34 is a plan perspective view showing a connection component of the conventional semiconductor component test apparatus, and FIG. 35 is a bottom perspective view showing the connection component of FIG. 34.

Each connection component 40 includes a connection component body 41 made of a synthetic resin and a plurality of contact pins 43 spaced apart from each other along a longitudinal direction of the connection component body 41 in a plurality of rows. The connection component body 41 has concave portions formed on the underside thereof to insert the protruding portions of the upper supports 55, and the contact pins 43 are facingly disposed on both sides of the concave portions.

If a connection component insertion portion 41a of the connection component 40 is inserted into the groove portion formed on top of the connector 50, the protruding portions of the upper supports 55 of the connector 50 are inserted into the concave portions of the connection component 40, and the contact pins 43 of the connection component 40 are located to face the connector pins 53.

If the number of protruding portions of the upper supports 55 is two, the number of concave portions of the connection component 40 is two, and the contact pins 43 and the connector pins 53 are arranged in four rows, respectively.

The connection component 40 is inserted into the concave groove portion of the connector 50, and if the handles 52 are rotated to allow the cam 52a to pressurize the connector pins 53 arranged on both sides of the cam 52a outward, the connector pins 53 are pushed to the left and right sides and then protrude through the open portions to the left and right sides on the top of the upper support, so that they come into contact with the contact pins, thereby achieving contacts.

In the conventional semiconductor component test apparatus, the connection components 40 are fixed to the substrate 30 by means of rivets, which makes the fixing work inconvenient, and if there is a need to separate the connection components 40 from the substrate 30 after fixing, it is not easy to perform the separating work. Further, contact stability between the connector pins 53 and the contact pins 43 may be not ensured, and the connection components 40 may be damaged or broken due to the lack of rigidity thereof.

The concave side support surfaces 113g whose end portions are connected to the outer member pin insertion groove 111c.

As shown in FIGS. 10 and 13, the intermediate member 120 is disposed between the outer members 110 in the transverse direction. The intermediate member 120 has a plate-shaped intermediate member body 121 extended in the longitudinal direction and intermediate member side portions 123 are formed on both longitudinal ends of the intermediate member body 121 in such a manner as to protrude in the transverse direction.

The intermediate member body 121 has first intermediate member surfaces 121c formed slantly on both transverse sides thereof in such a manner as to become increased in thickness from the top to the bottom and intermediate member pin insertion grooves 121a concavely formed spaced apart from the first intermediate member surfaces 121c in the down direction at positions facing the outer member pin insertion grooves 111c in such a manner as to be extended in the longitudinal direction. The intermediate member pin insertion groove 121a has a plurality of intermediate member pin protrusions 121b spaced apart from each other in the longitudinal direction in such a manner as to protrude therefrom toward the outer members 110 in the transverse direction.

Tops of the intermediate member side portions 123 protrude more upward than top of the intermediate member body 121. The intermediate member side portions 123 have intermediate member side protrusions 123h protruding from tops thereof in the longitudinal direction.

On both transverse sides of the intermediate member side portions 123 are formed intermediate member axial grooves 123a extended in the longitudinal direction therefrom in such a manner as to be concave inward in the transverse direction.

The PCB seating portions 123e have PCB fastening holes 123f penetrated thereinto in the transverse direction. The PCB fastening holes 123f communicate with the PCB fastening holes 113f of the outer members 110.

As shown in FIGS. 14 and 15, the two pin modules 140 are disposed between the intermediate member 120 and one side outer member 110 and the two pin modules 40 are disposed between the intermediate member 120 and the other outer member 110 on both transverse sides of the intermediate member 130.

Each pin module 140 includes a bar-shaped pin module body 141 extended in the longitudinal direction, a plate-shaped pin module support 143 extended upward from the pin module body 141 in the longitudinal direction, and a plurality of pins 142 arranged in the longitudinal direction and penetrated into the pin module body 141 and the pin module support 143 in the up and down direction in such a manner as to allow top ends thereof to protrude upward from the pin module support 143 and to allow bottom ends thereof to protrude downward from the pin module body 141.

The pin module 140 includes a pin module coupling groove 147 and a pin module coupling protrusion 145 formed on one side of the pin module body 141 coming into contact with the pin module 140 adjacent thereto in such a manner as to be spaced apart from each other in the longitudinal direction. The pin module coupling groove 147 and the pin module coupling protrusion 145 are spaced apart from each other in the longitudinal direction of the pin module 140. The pin module coupling protrusion 145 of the adjacent pin module 140 is inserted into the pin module coupling groove 147, and the pin module coupling groove 147 of the adjacent pin module 140 inserts the pin module coupling protrusion 145 thereinto.

A plurality of concave pin module body grooves 141a are spaced apart from each other in the longitudinal direction on the opposite transverse surface to the surface where the pin module coupling groove 147 and the pin module coupling protrusion 145 of the pin module body 141 are formed in such a manner as to be concavely penetrated in the up and down direction.

The pin module body 141 has pin module protrusion portions 149 protruding downward from both longitudinal sides thereof in such a manner as to locate the plurality of pins 142 therebetween. The lower ends of the pin module protrusion portions 149 are slant downward therefrom.

As shown in FIGS. 16 and 17, the top member 130 whose both transverse sides are inserted into the outer members 110 so that the top member 130 is disposed on top of the intermediate member 120. The top member 130 includes a bar-shaped top member body 131 extended in the longitudinal direction and top member protruding portions 133 protruding upward from the top member body 131 in such a manner as to be spaced apart from each other in the transverse direction and extended in the longitudinal direction.

The top member body 131 has top member concave portions 131a concave downward from the underside thereof in such a manner as to be extended in the longitudinal direction. The two top member concave portions 131a are spaced apart from each other in the transverse direction. The top member concave portions 131a whose both transverse sides are slant toward the lower portions thereof so that a distance between both transverse sides becomes distant.

Top member pin holes 135 are extended from the top member concave portions 131a to the top member protruding portions 133 in such a manner as to be exposed toward the transverse direction of the top member protruding portions 133. The top member pin holes 135 are formed in four rows so that the two rows thereof are formed on one top member concave portion 131a and one top member concave portion 131a and the two rows thereof are formed on the other top member concave portion 131a and the other top member concave portion 131a.

Top member body protrusions 131b protrude from both transverse sides of the top member body 131 in the transverse direction in such a manner as to be inserted into the top member insertion grooves 111b. A plurality of concave top member protrusion grooves 131c are spaced apart from each other on each top member body protrusion 131b in the longitudinal direction in such a manner as to be penetrated in the up and down direction.

The two driving shafts 160 are rotatably disposed between the intermediate member 120 and the outer members 110 under the top member 130 and have end portions protruding from one longitudinal side. Each driving shaft 160 has a shape of an oval section in such a manner as to be extended in the longitudinal direction.

The handles 170 are disposed on the protruding end portions of the driving shafts 160. Each handle 170 includes a first handle extended in a vertical direction to the corresponding driving shaft 160 and a second handle spaced apart from a coupled portion between the driving shaft 160 and the first handle in the vertical direction to the driving shaft 160 in such a manner as to be extended in the longitudinal direction.

So as to assemble the first connector 100, as shown in FIG. 18, the pin modules 140 are first coupled to the outer members 110. In detail, the pin module bodies 141 of the pin modules 140 are inserted into the outer member pin insertion grooves 111c, and the pin insertion protrusions 111e are inserted into the pin module body grooves 141a. Movements of the pin modules 140 in the longitudinal direction are prevented through the pin insertion protrusions 111e and the pin module body grooves 141a.

Also, the pin insertion protrusions 111e are slantly formed in such a manner as to become reduced in thickness in the longitudinal direction as they are extended inward in the transverse direction, and as the pin module support 143 is distant from the transverse sides of the pin module body grooves 141a, an inclined surface is formed so that a distance between their transverse sides becomes long, thereby allowing the pin modules 140 to be easily coupled to the outer member 110.

One pin module 140 is coupled to the pin module 140 coupled to the outer member 110. The pin module coupling protrusion 145 of the adjacent pin module 140 is inserted into the pin module coupling groove 147 of the pin module 140, and the pin module coupling groove 147 of the adjacent pin module 140 inserts the pin module coupling protrusion 145 of the pin module 140 thereinto.

Both longitudinal ends of the pin module body 141 of one side pin module 140 of the two pin modules 140 come into contact with the concave side support surfaces 113g, and both longitudinal ends of the pin module body 141 of the other side pin module 140 come into contact with the concave intermediate member support surfaces 123d.

As a result, the two pin modules 140 disposed between the intermediate member 120 and the outer member 110 are more rigidly seated onto the intermediate member 120 and the outer member 110, so that changes in position according to their operations are prevented to allow the electrical contacts of the pins to be stably maintained.

As shown in FIG. 19, each driving shaft 160 is inserted into the outer member axial grooves 113a in such a manner as to be rotatably disposed between the pin modules 140. The driving shaft 160 is rotated between the pins 142 spaced apart from each other in the transverse direction to pressurize the pins 142 outward in the transverse direction. The handle 170 is disposed on the portion of the driving shaft 160 protruding outward in the longitudinal direction of the outer member 110.

The outer member 110 and the intermediate member 120, to which the pin modules 140 are coupled, are then coupled to each other. The pin module body 141 of the pin module 140 is inserted into the intermediate member pin insertion groove 121a, and the intermediate member pin protrusions 121b are inserted into the pin module body grooves 141a. Through the intermediate member pin protrusions 121b and the pin module body grooves 141a, the pin module 140 is prevented from being moved in the longitudinal direction.

Also, the intermediate member pin protrusions 121b are slantly formed in such a manner as to become reduced in thickness in the longitudinal direction as they are toward the outer member 110 in the transverse direction, and as the pin module support 143 is distant from the transverse sides of the pin module body grooves 141a, an inclined surface is formed so that a distance between their transverse sides becomes long, thereby allowing the pin modules 140 to be easily coupled to the outer member 110.

The PCBs 150 are disposed between one side outer member 110 and the intermediate member 120 adjacent to each other and between the other side outer member 120 and the intermediate member 120 adjacent to each other. Each PCB 150 has electrical terminals adapted to transfer electrical signals. Screws are fastened to PCB holes formed on the PCBs 150, the PCB fastening holes 113f of the outer members 110, and the PCB fastening holes 133f of the intermediate member 120, so that the PCBs 150 are coupled to the outer members 110 and the intermediate member 120.

The outer member side portions 113 of the outer member 110 come into contact with the intermediate member side portions 123 of the intermediate member 120, thereby allowing coupling therebetween. Further, the end portions of the outer member axial grooves 113a come into contact with the intermediate member axial grooves 123a to form one shaft hole, so that the driving shaft 160 is rotatably inserted into the shaft hole.

As shown in FIG. 20, both transverse sides of the top member 130 are inserted into the outer members 110 in such a manner as to be disposed on top of the intermediate member 120.

The top member body protrusions 131b of the top member 130 are inserted into the top member insertion grooves 111b of the outer members 110, and the top member insertion protrusions 111d are inserted into the top member protrusion grooves 131c. Through the top member insertion protrusions 111d and the top member protrusion grooves 131c, the top member 130 is prevented from being moved in the longitudinal direction.

The two pin modules 140 are located at each top member concave portion 131a of the top member 130, so that the pins 142 are inserted into the top member pin holes 135. The pins 142 are exposed to the transverse sides of the top member protrusions 133 in such a manner as to be arranged in the longitudinal direction.

In the same manner as described with reference to FIGS. 18 to 20, to the opposite side of the intermediate member 120 are coupled the two pin modules 140, the driving shaft 160 disposed between the pin modules 140, the handle 170 disposed on the driving shaft 160, and the outer member 110. The outer members 110 located on both transverse sides of the intermediate member 120 are coupled to each other in such a manner as to allow the end portions of the outer member protrusion portions 115 to come into contact with each other.

The first connector 100 has the insertion groove 101 formed on top thereof. The insertion groove 101 is defined by the body inner surfaces 111a formed on the outer member body 111 in such a manner as to face each other in the transverse direction and the side inner surfaces 115a formed on the outer member protrusion portions 115 in such a manner as to face each other in the longitudinal direction. The insertion groove 101 has a shape of a rectangular section and is concave upward. A transverse distance between the body inner surfaces 111a and a longitudinal distance between the side inner surfaces 115a are increased toward the open end portion of the insertion groove 101.

As shown in FIGS. 21 to 23, the second connector 200 includes a connector body 210 and a plurality of pins 220.

The connector body 210 has a shape of a rectangular section in such a manner as to be extended in the longitudinal direction, and a connector insertion portion 211 is extended downward from a connector projection surface 213 protruding downward from the underside of the connector body 210.

The connector body 210 has two connector concave portions 210a formed on the lower portion thereof in such a manner as to be open downward to insert the top member protruding portions 133. The two connector concave portions 210a are spaced apart from each other in the transverse direction.

First insertion surfaces 211a as the outer surfaces of the connector insertion portion 211 extended in the transverse direction and second insertion surfaces 211b as the outer surfaces of the connector insertion portion 211 extended in the longitudinal direction are formed in such a manner as to allow a distance between the first insertion surfaces 211a and a distance between the second insertion surfaces 211b to become reduced as they go toward the ends of the connector insertion portion 211. The connector insertion portion 211 has slant insertion surfaces 211c formed along the end edges thereof.

As shown in FIG. 27, the connector body 210 has connector body pin holes 217 formed thereon in such a manner as to be extended upward and open on the top thereof and to allow bottoms thereof to communicate with the connector concave portions 210a. The connector body pin holes 217 are formed on both transverse sides of each connector concave portion 210a in such a manner as to be spaced apart from each other in the longitudinal direction. The connector body pin holes 217 communicate with the connector concave portions 210a in the directions facing the transverse directions of the connector concave portions 210a. Each connector body pin hole 217 has an expanded pin hole portion 219 expanded in the transverse direction from the top thereof. The expanded pin hole portions 219 are expanded toward both transverse sides thereof, while placing the respective connector concave portions 210a therebetween.

The pins 220 are inserted into the connector body pin holes 217 in such a manner as to allow top ends thereof to protrude upward from the top of the connector body 210 and to allow bottom ends thereof to be exposed to the connector concave portions 210a through the connector body pin holes 217. The pins 220 are arranged in the longitudinal direction on both transverse sides of each connector concave portion 210a. The pins 220 are arranged on each connector concave portion 210a in two rows, and accordingly, the pins 220 are arranged on the respective connector concave portions 210a in four rows.

Hereinafter, a transverse side toward the center of the connector concave portion 210a is called transverse inside (or transversely inward side), and a side toward transversely facing surfaces of the connector concave portion 210a is called transverse outside (or transversely outward side).

Each pin 220 includes a first bar-shaped pin portion 221 extended in the up and down direction, a second pin portion 223 bent from top of the first pin portion 221 in such a manner as to allow an end portion thereof to be slantly extended toward the expanded direction of the expanded pin hole portion 219, a third pin portion 225 bent from top of the second pin portion 223 in such a manner as to allow an end portion thereof to be slantly extended toward the opposite direction to the second pin portion 223, and a fourth pin portion 227 bent from top of the third pin portion 225 in such a manner as to allow an end portion thereof to be slant toward the connector body 210. The bent portions of the pin 220 are curvedly formed.

The first pin portion 221 in each connector body pin hole 217 is located at the connector concave portion 210a in such a manner as to be exposed in the transverse direction of the connector concave portion 210a, the bent portion between the second pin portion 223 and the third pin portion 225 comes into contact with the side of the expanded pin hole portion 219, and the bent portion between the third pin portion 225 and the fourth pin portion 227 and the fourth pin portion 227 are exposed to the outside of the connector body 210.

The bent portion between the third pin portion 225 and the fourth pin portion 227 are located closer at the transverse inside of the connector body 210 than the bent portion between the second pin portion 223 and the third pin portion 225.

A distance between the bent portions between the third pin portion 225 and the fourth pin portion 227 of the pins facing in each connector concave portion 210a is shorter than a transverse width of the connector concave portion 210a.

When the bent portion between the third pin portion 225 and the fourth pin portion 227 is contactedly pressurized, an external force is generated to allow displacement to be applied to the first pin portion 221 toward the transverse outside, so that the first pin portion 221 comes into close contact with the connector body pin hole 217.

As shown in FIG. 28, the pin 220 further includes an upward expanded portion 226 expanded upward between the second pin portion 223 and the third pin portion 225 in such a manner as to be parallel with the first pin portion 221. The upward expanded portion 226 comes into contact with the vertical inner surface of the expanded pin hole portion 219, and otherwise, it may be separated therefrom with a fine tolerance.

As shown in FIG. 29, the pin 220 is configured to allow the third pin portion 225 and the fourth pin portion 227 to protrude upward from the connector body 210 and otherwise to allow a portion of a top of the first pin portion 221, the third pin portion 225 and the fourth pin portion 227 to protrude upward from the connector body 210.

As shown in FIGS. 24 and 25, the connector insertion portion 211 of the second connector 200 is coupledly inserted into the insertion groove 101 of the first connector 100.

The top member protruding portions 133 are inserted into the connector concave portions 210a, and the ends of the connector insertion portion 211 are coupledly located between the outer members 110 and the top member 130.

When the connector insertion portion 211 is inserted into the insertion groove 101, the second connector 100 can be easily coupled to the first connector 100 through the first insertion surfaces 211a and the second insertion surfaces 211b slant of the connector insertion portion 211. Through the slant insertion surfaces 211c of the connector insertion portion 211, the top end portions of the insertion groove 101, which are coupled to the slant insertion surfaces 211c, can be easily adjusted in position.

The pins 142 of the first connector 100 and the pins 220 of the second connector 200 are facingly arranged in the transverse direction.

As shown in FIG. 26, a test head A is built on the first connector 100 by means of a bolt B. The bolt B is inserted into the first connector fastening hole 123g of the first connector 100 and is then fastened to a fastening portion A1 of the test head A.

The bolt B includes a bolt head portion B1, a bolt guide portion B2 having a protruding surface from the bolt head portion B in such a manner as to be extended downward, and a bolt fastening portion B3 having a bolt protruding portion B4 from the bolt guide portion B2 in such a manner as to be extended downward and screw-fastened to the fastening portion A1 of the test head A.

If the bolt fastening portion B3 of the bolt B is screw-fastened to the test head A, the bolt protruding portion B4 pressurizes the test head A so that the first connector 100 located between the bolt head portion B1 and the test head A is coupled to the test head A.

The first connector 100 is slidable laterally between the bolt head portion B1 and the test head A, and a tolerance t is formed laterally between the bolt guide portion B2 and the first connector fastening hole 123g. Even if the connector insertion portion 211 and the insertion groove 101 are misaligned in position at the time when the second connector 200 is inserted into the first connector 100, the first connector 100 is moved by means of the clearance t to allow the connector insertion portion 211 and the insertion groove 101 to be automatically aligned, thereby achieving easy coupling.

A horizontal direction in FIG. 38 is called “transverse direction”, a vertical direction is called “up and down direction”, and a vertical direction with respect to the surface of ground is called “longitudinal direction”.

As shown in FIG. 36, each connection component 140 of the semiconductor component test apparatus according to the present invention is coupled to the substrate 30 through fixing pins 147 and coupling members 146.

The connection component 140 includes connection component bodies 141, contact pins 143, a connection component support 142, the fixing pins 147, and the coupling members 146.

The first body extension portions 1411 are formed on both transverse sides of the body bottom 1415. The first body extension portions 1411 are extended upward from the body bottom 1415 in such a manner as to face each other. Concave portions between the first body extension portions 1411 and the body bottom 1415 are formed open to upward and longitudinal directions, and first body projection portions 1417 protrude upward from the transverse outsides of the first body extension portions 1411.

The second body extension portions 1413 are extended upward from the first body extension portions 1411, while having second body projection portions 1416 formed at the insides facing the first body extension portions 1411. The second body projection portions 1416 are formed at the positions separated upward from the first body projection portions 1417.

The body locking projections 1412 are formed on both longitudinal sides of each body bottom 1415. The body locking projections 1412 protrude over the first body extension portions 1411.

The connection component bodies 141 have first body grooves portions 1419 and body pin holes 1414.

The first body groove portions 1419 are open downward on both transverse sides of each body bottom 1415.

The body pin holes 1414 are penetrated in the up and down direction into each first body extension portion 1411. The body pin holes 1414 are spaced apart from each other along the longitudinal direction of the first body extension portion 1411. Top ends of the body pin holes 1414 are open to the second body projection portions 1416, and the bottom ends thereof communicate with the first body groove portions 1419.

Concave contact pin grooves 1413a are formed on the surfaces of the body pin holes 1414 facing the second body extension portions 1413. The contact pin grooves 1413a are spaced apart from each other along the longitudinal direction of the second body extension portion 1413. The contact pin grooves 1413a are extended to tops of the second body extension portions 1413, while allowing bottom ends thereof to be connected to the body pin holes 1414.

The contact pins 143 are penetrated into the body pin holes 1414 so that tops thereof are inserted into the contact pin grooves 1413a.

The contact pins 143 are spaced apart from each other along the longitudinal direction of the connection component bodies 141, while being arranged in a plurality of rows. The contact pins 143 are penetrated into the body pin holes 1414. The bottom portions of the contact pins 143 are extended to the first body groove portions 1419 in such a manner as to be exposed under the connection component bodies 141, and the top portions thereof are extended to the contact pin grooves 1413a of the second body extension portions 1413 in such a manner as to be inserted into the contact pin grooves 1413a.

As shown in FIG. 40, a concave pin portion 143a is concavely formed at the inner surface of each contact pin 143 in such a manner as to be extended along the longitudinal direction of the contact pin 143. The concave pin portion 143a has a sectional shape of “v”. Through the concave pin portion 143a, two-point contacts can be made at the time when the connector pins 53 come into contact with the contact pins 143, thereby achieving stable contacts.

The connection component 140 is configured to have the two connection component bodies 141 disposed in one connection component support 142. The connection component support 142 is adapted to surround the outsides of the connection component bodies 141 parallel with each other.

The connection component support 142 is made of a metal material. As the connection component support 142 made of the metal supports the outsides of the connection component bodies 141, no damage or deformation on the connection component 140 may occur even under external impacts.

The connection component support 142 includes support bottoms 1422, a supporting portion, and a support wall 1426.

The support bottoms 1422 have shapes of bars extended in the longitudinal direction of the connection component 140. The support bottoms 1422 are spaced apart from each other on both sides of the support wall 1426.

Each support bottom 1422 has a plurality of support fixing pin holes 1422a spaced apart from each other in the longitudinal direction. The support fixing pin holes 1422a are formed at positions corresponding to the body fixing pin holes 1418.

The supporting portion is extended upward and downward from the edges of the support bottoms 1422. The supporting portion includes first supporting portions 1421 and second supporting portions 1425.

The first supporting portions 1421 are disposed along the edges of the support bottoms 1422. The first supporting portions 1421 are extended downward from the support bottoms 1422. The first supporting portions 1421 have first support projection portions 1429a formed at the insides facing in the transverse direction. The first support projection portions 1429a are located between tops and bottoms of the support bottoms 1422. Through the formation of the first support projection portions 1429a, the first supporting portions 1421 located on both transverse sides of the support bottoms 1422 are spaced apart from the support bottoms 1422 in the transverse direction.

Concave locking groove portions 1424 are formed on the lower ends of both longitudinal sides of the first supporting portions 1421.

The second supporting portions 1425 are extended upward from the first supporting portions 1421, while having second support projection portions 1423 formed upward from the transverse outsides of the support bottoms 1422.

The support wall 1426 is extended upward from the transverse center of the support bottoms 1422 in such a manner as to allow both longitudinal ends thereof to be connected to the supporting portion. The lower end of the support wall 1426 is located more upward than the lower ends of the support bottoms 1422. The support wall 1426 and the supporting portion have upwardly open concave support portions 1427 located on both transverse sides of the support wall 1426.

The connection component support 142 has extension portion insertion holes 1429.

The extension portion insertion holes 1429 are penetrated in the up and down direction into the support bottoms 1422 in such a manner as to be extended in the longitudinal direction. The extension portion insertion holes 1429 are formed on both sides of the support bottoms 1426 and the transverse insides of the supporting portion. The extension portion insertion holes 1429 formed on both sides of the support bottoms 1426 communicate with each other under the support wall 1426.

If the connection component support 142 is coupled to the connection component bodies 141, the connection component bodies 141 are moved upward toward both sides of the support wall 1426 to allow the first body extension portions 1411 and the second body extension portions 1413 to be inserted into the extension portion insertion holes 1429. The outer surfaces of the first body extension portions 1411 and the second body extension portions 1413 supportedly come into contact with the inner surfaces of the supporting portion and the support wall 1426. The first body projection portions 1417 formed on the transverse outsides of the connection component bodies 141 lockedly come into contact with the first support projection portions 1429a, and the first body projection portions 1417 formed on the transverse insides of the connection component bodies 141 lockedly come into contact with the lower end of the support wall 1426. Further, the body locking projections 1412 of the connection component bodies 141 are inserted into the locking groove portions 1424.

The support bottoms 1422 are inserted between the concave portions formed by the first body extension portions 1411 and the body bottoms 1415, and the support fixing pin holes 1422a and the body fixing pin holes 1418 communicate with each other to form fixing pin holes through which the fixing pins 147 are passed.

The connection component 140 and the coupling members 146 are located on both sides of the substrate 30, while placing the substrate 30 therebetween, and they are coupled to each other by means of the fixing pins 147.

The fixing pins 147 are passed through the fixing pin holes. The fixing pins 147 have heads locked onto the support fixing pin holes 1422a and are sequentially passed through the support fixing pin holes 1422a, the body fixing pin holes 1418 and substrate fixing pin holes 30a formed on the substrate 30. The end portions of the fixing pins 147 are locked onto pin locking portions of the coupling members 146 disposed on the underside of the substrate 30.

As shown in FIG. 37, the coupling members 146 are disposed on the underside of the substrate 30. Each coupling member 146 has a shape of a plate-shaped bar extended in the longitudinal direction of the connection component 140. A reference numeral 33 in FIG. 38 denotes an insulation film disposed between the coupling member 146 and the substrate 30.

The coupling member 146 has a plurality of pin locking portions spaced apart from each other along the longitudinal direction. Each pin locking portion has two pin locking members 1461 incised to a shape of “⊏” so that the two pin locking members 1461 have one side end connected to the coupling member 146 and free end portions facing each other.

Each fixing pin 147 is inserted between the pin locking members 1461 in such a manner as to allow both side peripheries thereof to come into contact with the pin locking members 1461. A reference numeral 1463 denotes a coupling member installing hole through which the coupling member 146 is fixedly coupled to the substrate 30 by means of a bolt.

Locking contact portions 1461a as the free ends of the pin locking members 1461 have shapes of concave arch. As a result, contact areas between the locking contact portions 1461a and the fixing pin 147 are increased at the time when the fixing pin 147 is inserted into the pin locking members 1461, thereby allowing the fixing pin 147 to be rigidly coupled to the pin locking members 1461.

If the fixing pins 147 are inserted into the pin locking portions, the pin locking members 1461 are pushed downward by means of the fixing pins 147 in such a manner as to be slantly deformed downward to cause a distance between the free ends to become long, thereby locating the fixing pins 147 between the free ends.

The pin locking members 1461 are slantly bent downward from the coupling member 146 to allow the facing free ends thereof to be spaced apart from each other.

If the fixing pins 147 are inserted between the free ends of the pin locking portions, the pin locking members 1461 are deformedly pushed downward so that the slant angles of the pin locking members 1461 are increased and the distance between the free ends are also long, thereby locating the fixing pins 147 between the free ends.

The pin locking members 1461 are slant to allow the free ends to be moved downward at the time when the fixing pins 147 are inserted between the free ends, and accordingly, the fixing pins 147, which coupledly come into contact with the free ends on both sides thereof, are supported rigidly against the pin locking members 1461. If the fixing pins 147 are pulled upward, a distance between the free ends becomes short, and accordingly, pressurizing forces applied from both sides of the fixing pins 147 are increased. Once the fixing pins 147 are coupled to the pin coupling portions, as a result, they are in rigidly coupled state with the pin locking portions, thereby making it hard to separate them from the pin locking portions.

The present invention may be modified in various ways and may have several exemplary embodiments. Specific exemplary embodiments of the present invention are illustrated in the drawings and described in detail in the detailed description. However, this does not limit the invention within specific embodiments and it should be understood that the invention covers all the modifications, equivalents, and replacements within the idea and technical scope of the invention.
