SUMMARY OF THE INVENTION
Problems to be Solved
Incidentally, it is possible to obtain a structure that prevents a decrease in the shielding performance by an outer conductor additionally covering the circuit-substrate side of an inner conductor when a shield connector is installed on a circuit substrate. An outer shell body manufactured through die-casting or the like can be used for a portion of the outer conductor that covers the circuit-substrate side of the inner conductor. Here, it is not easy to integrally form the outer shell body and a tubular connection portion. For this reason, there are cases where a through hole is formed in the outer shell body, and a separate outer conductor tube that includes a tubular connection portion is inserted into and attached to the through hole. Here, a configuration can be adopted in which a press-fitting blade corresponding to the locking pieces of Patent Document 1 and the lance portion of Patent Document 2 is formed on the outer conductor tube, and is locked on the inner peripheral surface of the through hole of the outer shell body. However, when external force acts on the outer conductor tube in a state where the outer conductor tube is attached to the outer shell body, there is the possibility that the axial center of the outer conductor tube will be displaced, and the outer conductor will come out of alignment. In addition, there is an issue that it is not easy to keep the outer conductor tube from coming out of alignment using the press fitting blade only.
In view of this, an object of the present disclosure is to provide a shield connector that can keep an outer conductor tube from coming out of alignment.
Means to Solve the Problem
A shield connector according to the present disclosure includes; an inner conductor, an outer conductor that surrounds the inner conductor, and a dielectric body disposed between the inner conductor and the outer conductor, the outer conductor includes a tubular outer conductor tube and an outer shell body, the outer shell body includes a through hole in which the outer conductor tube is disposed, the outer conductor tube includes: a press-fitting blade that protrudes outward in a radial direction and is locked on an inner peripheral surface of the through hole of the outer shell body, and a holding protrusion portion that protrudes outward in the radial direction and comes into contact with the inner peripheral surface of the through hole of the outer shell body, the press-fitting blade is disposed at two end portions in a radial direction of the outer conductor tube, and the holding protrusion portion of the outer conductor tube is disposed at a position displaced from the press-fitting blades in a circumferential direction when the outer conductor tube is viewed from an axial direction.
Effect of the Invention
According to the present disclosure, it is possible to provide a shield connector that can keep an outer conductor tube from coming out of alignment.

DETAILED DESCRIPTION TO EXECUTE THE INVENTION
Description of Embodiments of the Disclosure
First, embodiments of the present disclosure will be listed and described.
(1) A shield connector according to the present disclosure includes: an inner conductor, an outer conductor that surrounds the inner conductor, and a dielectric body disposed between the inner conductor and the outer conductor, the outer conductor includes a tubular outer conductor tube and an outer shell body, the outer shell body includes a through hole in which the outer conductor tube is disposed, the outer conductor tube includes: a press-fitting blade that protrudes outward in a radial direction and is locked on an inner peripheral surface of the through hole of the outer shell body, and a holding protrusion portion that protrudes outward in the radial direction and comes into contact with the inner peripheral surface of the through hole of the outer shell body, the press-fitting blade is disposed at two end portions in a radial direction of the outer conductor tube, and the holding protrusion portion of the outer conductor tube is disposed at a position displaced from the press-fitting blades in a circumferential direction when the outer conductor tube is viewed from an axial direction.
In a state where the outer conductor tube is attached to the outer shell body, the press-fitting blades formed at the two end portions in the radial direction of the outer conductor tube are locked on the inner peripheral surface of the through hole of the outer shell body, and, furthermore, at a position displaced from the press-fitting blades in the circumferential direction as viewed from the axial direction, the holding protrusion portion is in contact with the inner peripheral surface of the through hole of the outer shell body. Thus, this configuration makes it possible to maintain the axial center of the outer conductor tube, and keep the outer conductor tube from coming out of alignment. Note that the outer conductor coming out of alignment in this case refers to a case where, when the outer conductor and a partner outer conductor are connected, the axial centers of the outer conductors do not match, and misalignment (unconformity) may occur.
(2) Preferably, the holding protrusion portion of the outer conductor tube is disposed at a position displaced from the press-fitting blades in the axial direction.
With the above configuration, it is possible to keep the outer conductor tube from having an orientation inclined with respect to the outer shell body from the axial direction.
(3) Favorably, a plurality of holding protrusion portions are arranged on the outer conductor tube at an interval in the circumferential direction.
The above configuration makes it possible to reliably keep the outer conductor tube from coming out of alignment.
(4) Favorably, the holding protrusion portions are respectively disposed at upper, lower, right and left sections of an outer peripheral surface of the outer conductor tube, as viewed from the axial direction.
The above configuration makes it possible to keep the outer conductor tube from coming out of alignment in almost all the directions, from four directions, namely upward, downward, leftward, and rightward directions.
(5) Favorably, a housing made of a synthetic resin that is to be coupled to the outer conductor is provided, the housing includes an insertion hole in which an end portion of the outer conductor tube that has passed through the through hole is disposed, and housing-side holding protrusion portions that protrude from an inner peripheral surface of the insertion hole and come into contact with an outer peripheral surface of the end portion of the outer conductor tube, and the plurality of housing-side holding protrusion portions are arranged in the housing at an interval in the circumferential direction.
With the above configuration, the housing-side holding protrusion portions can come into contact with the outer peripheral surface of the outer conductor tube in a compressed or crushed state, and thus it is possible to loosen the dimension tolerances of the housing and the outer conductor. In addition, the plurality of housing-side holding protrusion portions arranged at an interval in the circumferential direction come into contact with the outer peripheral surface of the end portion of the outer conductor tube, and thereby it is possible to correct displacement of the axial center of the end portion of the outer conductor tube.

As shown in FIGS. 20 and 21, in a central portion in the width direction of the upper surface of the front end portion of the bottom portion 59, the press-fitting protrusion portion 75 is formed to protrude. The press-fitting protrusion portion 75 has a columnar shape, and is formed with a uniform cross-sectional shape in the up-down direction, except for an upper end portion. Also, on the two side surfaces of the press-fitting protrusion portion 75, a pair of contact ribs 68 extending in the up-down direction are formed. The contact ribs 68 come into contact with the inner surface of the recessed press-fitting portion 45.
As shown in FIG. 20, the substrate-side outer shell body 14 includes a pair of second coupling protrusion portions 76 that protrude outward in the width direction from the front end of the two side surfaces of the bottom portion 59. Pressing ribs 78 having an arc-shaped cross-section and extending in the up-down direction are respectively formed on the rear surfaces of the second coupling protrusion portions 76. In a state where the second coupling protrusion portions 76 are fitted into the fitting grooves 34 of the housing 18, the pressing ribs 78 of the second coupling protrusion portions 76 come into contact with the front surfaces of the second locking protrusions 32 in a pressing state (see FIG. 13).
As shown in FIG. 21, a plurality of opening portions 81 are formed in the substrate-side outer shell body 14. The opening portions 81 have a rectangular cross-section, and are disposed on right and left sides of the substrate-side outer shell body 14 with the groove portion 52 interposed therebetween, at front and rear positions. The opening portions 81 on the front side are positioned in front of the standing portion 62 and behind the engaging protrusion portions 49 formed on the bottom portion 59, pass through the bottom portion 59, and are open to a bottom surface 92 (surface that faces downward, see FIG. 12). The opening portions 81 on the rear side are defined by the back portion 61, the standing portion 62, and the partition portion 63, pass through the bottom portion 59 in the same manner, and are open to the bottom surface 92. The partition portion 63 separates the opening portions 81 on the rear side adjacent in the width direction.
As shown in FIG. 2, the dielectric bodies 16 and 17 are fitted into the opening portions 81. The inner conductors 11 and 12 respectively mounted to the dielectric bodies 16 and 17 cause substrate connection portions 107 to be described later to protrude downward from the bottom surface 92 of the bottom portion 59 through the opening portions 81. The substrate connection portions 107 are inserted into connection holes 202 formed in the circuit substrate 200, and are electrically connected to conductive portions (not illustrated).

The mount portions 84 to 87 slightly protrude downward from the bottom surface 92 of the bottom portion 59. The lower end surfaces of the mount portions 84 to 87 have flat shapes, and are electrically connected to conductive portions for the ground of the circuit substrate 200 through soldering.
Specifically, the mount portions include front mount portions 84 extending in the left-right direction in front of the front opening portions 81, lateral mount portions 85 extending in the front-rear direction on the right and left of each of the opening portions 81, and shared mount portions 86 extending in the left-right direction between the front opening portions 81 and the rear opening portions 81. In addition, complementary mount portions 87, which are mount portions, are also formed on the right and left of a depressed portion 91 to be described later.
Recessed regression portions 88 are provided in a rear end portion of the bottom surface 92 of the bottom portion 59. The rear ends of the recessed regression portions 88 are open to a back surface 93 intersecting the bottom surface 92, on the substrate-side outer shell body 14. The recessed regression portions 88 have a rectangular cross-section, and are in communication with the opening portions 81 in front thereof, and are opened rearward and downward, and, on the other hand, the upper sides of the recessed regression portions 88 are closed by the back portion 61.
The recessed regression portions 88 are disposed above surface layer wiring (not illustrated) of the circuit substrate 200. Electrical connection between the substrate-side outer shell body 14 and the surface layer wiring is avoided due to the recessed regression portions 88.
The complementary mount portions 87 correspond to the recessed regression portions 88, and are formed to extend in the front-rear direction along the inner side edges positioned on the central side in the width direction of the bottom portion 59, from among the two side edges of the recessed regression portions 88.
As shown in FIG. 13, the depressed portion 91 is provided in a central portion in the width direction of the back surface 93 of the substrate-side outer shell body 14. As shown in FIG. 9, the depressed portion 91 is formed to extend in the up-down direction from the bottom portion 59 to the back portion 61 of the back surface 93 of the substrate-side outer shell body 14. The depressed portion 91 is provided to cover the bottom surface 92 and the back surface 93 of the substrate-side outer shell body 14, and is open rearward and downward.
The depressed portion 91 passes through the back portion 61, and is defined inside the partition portion 63. That is to say, the depressed portion 91 is formed within the thickness range of the partition portion 63. As shown in FIG. 8, an inner and farther surface 126 and an inner and upper surface 127 of the depressed portion 91 are disposed in parallel with, and respectively behind and below the groove portion 52, opposing the groove portion 52 in a back-to-back manner. A portion of the partition portion 63 that is between the depressed portion 91 and the groove portion 52 (see reference sign “a” in FIG. 8) is formed with a uniform thickness or an almost uniform thickness from the back portion 61 to the bottom portion 59. The thickness of a section of the partition portion 63 that corresponds to the depressed portion 91 is reduced. As shown in FIG. 13, the complementary mount portions 87 are disposed between the depressed portion 91 and the recessed regression portions 88 in the width direction, on the bottom surface 92 of the bottom portion 59. As shown in FIGS. 9 and 10, the lateral mount portions 85 positioned on the inner side in the width direction of the bottom surface 92 of the substrate-side outer shell body 14 (on the center side in the width direction) from among the lateral mount portions 85 are disposed so as to be visually recognizable through the depressed portion 91, in rear view of the substrate-side outer shell body 14.
Each outer conductor tube 15 is integrally formed by, for example, bending a conductive metal plate, and is formed to be thinner than the outer shell body 13 and the substrate-side outer shell body 14. As shown in FIG. 22, the outer conductor tube 15 includes a tubular connection portion 94 formed in a cylindrical shape and extending in the front-rear direction and a pair of projection portions 95 protruding downward from the right and left sides of a rear end portion of the tubular connection portion 94. The tubular connection portion 94 is formed by bending a plate material into a circular shape, and includes, at a lower end thereof, a butt edge 116 in which two ends in the circumferential direction butt against each other, as shown in FIG. 23.
The projection portions 95 has a tapered shape extending downward from the right and left ends of the upper half of a rear end portion of the tubular connection portion 94, in a state before the outer conductor tube 15 is inserted into a through hole 46 of the outer shell body 13. In addition, the projection portions 95 are formed in a rectangular shape in side view. Embossed contact protrusion portions 117 bulging outward are formed at sections close to the lower ends of the projection portions 95. The contact protrusion portions 117 have an arc-shaped cross-section.
In addition, press-fitting blades 118 are formed at intermediate portions in the front-rear direction of the tubular connection portion 94. A pair of press-fitting blades 118 are disposed at the right and left ends of the tubular connection portion 94 (the two ends in the radial direction), and are formed in a shape bulging outward, in front of a slit 119 extending along the up-down direction (which is also the circumferential direction of the tubular connection portion 94). Specifically, as shown in FIG. 22, the press-fitting blades 118 have an arc-shaped cross-section, and are each formed in a triangular shape whose length in the up-down direction decreases forward in side view. As shown in FIG. 3, the press-fitting blades 118 are pressure-fitted into and locked on the inner peripheral surface of a through hole 46 of the outer shell body 13.
In addition, inner-side protrusions 120 are formed in an intermediate portion in the front-rear direction of the tubular connection portion 94. As shown in FIG. 23, a pair of inner-side protrusions 120 are disposed at the right and left ends of the tubular connection portion 94, and are formed in a shape bulging inward, on the rear side of the slits 119 extending along the up-down direction (which is also the circumferential direction of the tubular connection portion 94). The inner-side protrusions 120 are locked on the outer surface of a dielectric body 16 or 17 disposed in the tubular connection portion 94 (see FIG. 3).
As shown in FIG. 22, a plurality of holding protrusion portions 121 are formed at sections of the tubular connection portion 94 that are on the rear side relative to the press-fitting blades 118 and on the front side relative to the projection portions 95. The holding protrusion portions 121 are formed in an embossed shape bulging outward from the tubular connection portion 94, and are formed to extend in the front-rear direction with a uniform (arc-shaped) cross-sectional shape.
In addition, as shown in FIG. 23, four holding protrusion portions 121 are provided at a certain interval in the circumferential direction, on the outer peripheral surface of the tubular connection portion 94. The protruding length of the press-fitting blades 118 from the outer peripheral surface of the tubular connection portion 94 is larger than that of the holding protrusion portions 121. When the tubular connection portion 94 is viewed from the axial direction (the front side or the rear side in the depth direction of FIG. 23), the holding protrusions portions 121 are displaced from the press-fitting blades 118 in the circumferential direction. Specifically, the holding protrusion portions 121 are disposed at four locations, namely upper right, lower right, upper left, lower left locations, based on upper, lower, right and left sections when the tubular connection portion 94 is viewed from the front. The lower right holding protrusion portion 121 in FIG. 23 is disposed near the butt edge 116 of the tubular connection portion 94. As shown in FIG. 4, the holding protrusion portions 121 come into contact with the inner peripheral surface of the through hole 46 of the outer shell body 13.
The outer conductor tube 15 is inserted into the through hole 46 of the outer shell body 13 from behind. A plurality of, (in the first embodiment, four) outer conductor tubes 15 are provided in correspondence with the through holes 46, and are formed in the same shape as shown in FIG. 1. The projection portions 95 of the outer conductor tube 15 abut on and are stopped by the stopper portions 112 (see FIG. 7), the press-fitting blades 118 are locked on the inner peripheral surface of the through hole 46 (see FIG. 3), and furthermore, the contact protrusion portions 117 come into contact with the restriction portions 113 in a state where the projection portions 95 elastically deform (see FIG. 6), and thereby the outer conductor tube 15 is held on the outer shell body 13 in a retained state. Front end portions of the tubular connection portions 94 of the outer conductor tubes 15 of the shield connector 10 protrude from the tubular portions 42 of the outer shell body 13 into the hood 21 (see FIG. 2).
(Dielectric Bodies)
As shown in FIG. 1, each of the dielectric bodies 16 and 17 includes a cylindrical main body portion 101 extending in the front-rear direction and a drawer portion 102 protruding downward from a rear end portion of the main body portion 101, and is formed in an L-shape in side view. A later-described horizontal portion 104 of an inner conductor 11 or 12 is inserted into the main body portion 101. A guide groove 103 extending in the up-down direction is formed in the rear surface of the drawer portion 102. The guide groove 103 is open rearward. A later-described extended portion 105 of the inner conductor 11 or 12 is fitted into the guide groove 103 from behind (see FIGS. 2 and 7).
The main body portions 101 of the dielectric bodies 16 and 17 are disposed in the through holes 46 of the outer shell body 13, in a state of being inserted into the tubular connection portions 94 of the outer conductor tubes 15. The drawer portions 102 of the dielectric bodies 16 and 17 are inserted into the opening portions 81 of the substrate-side outer shell body 14.
As shown in FIG. 1, the dielectric bodies include two types of dielectric bodies, namely the long dielectric bodies 16 and the short dielectric bodies 17. As shown in FIG. 2, the long dielectric bodies 16 are held on the outer conductors 13, 14, and 15 in a state where the main body portions 101 are disposed in the upper through holes 46 and the drawer portions 102 are inserted into the rear opening portions 81. The short dielectric bodies 17 are held on the outer conductors 13, 14, and 15 in a state where the main body portions 101 are disposed in the lower through holes 46 and the drawer portions 102 are inserted into the front opening portions 81.
(Inner Conductors)
As shown in FIG. 1, the inner conductors 11 and 12 are pin-like terminals, each include the horizontal portion 104 extending in the front-rear direction and the extended portion 105 extending downward from a rear end portion of the horizontal portion 104, and are formed in an L-shape in side view. The horizontal portion 104 includes a partner connection portion 106 protruding forward from the main body portion 101 in a state of being inserted into the main body portion 101 of a dielectric body 16 or 17. As shown in FIG. 2, the partner connection portion 106 protrudes into the hood 21, and is electrically connected to a partner inner conductor 303 in a state where the housing 18 and the partner connector 300 are fitted with each other. The extended portion 105 includes the substrate connection portion 107 protruding downward from the drawer portion 102 in a state of being inserted into the guide groove 103 of the drawer portion 102 of the dielectric body 16 or 17. The substrate connection portion 107 is formed with a smaller diameter than an upper portion of the extended portion 105.
As shown in FIG. 1, the inner conductors include two types of inner conductors, namely the long inner conductors 11 and the short inner conductors 12. The long inner conductors 11 are held by the long dielectric bodies 16. The short inner conductors 12 are held by the short dielectric bodies 17.
(Method for Attaching Shield Connector and Actions Thereof)
First, the horizontal portions 104 of the inner conductors 11 and 12 are respectively inserted into the main body portions 101 of the corresponding dielectric bodies 16 and 17 from behind, and are held thereon. The extended portions 105 of the inner conductors 11 and 12 are exposed on the rear surface side of the drawer portions 102 in a state of being inserted into the guide grooves 103. Next, the main body portions 101 of the dielectric bodies 16 and 17 are inserted into the tubular connection portions 94 of the corresponding outer conductor tubes 15 from behind, and are held thereon. In addition, the tubular connection portions 94 of the outer conductor tubes 15 are inserted into the corresponding through holes 46 of the outer shell body 13 from behind, and are held thereon.
At the end of a process of inserting a tubular connection portion 94, the projection portions 95 enter the cut grooves 111 from behind, and the contact protrusion portions 117 of the projection portions 95 slide along the restriction portions 113. At this time, the projection portions 95 are caused to elastically transform inward in the width direction (to the center side in the width direction of the outer conductor tubes 15) using a coupling section for the tubular connection portion 94 as a support.
When the tubular connection portion 94 is properly inserted into the through hole 46 of the outer shell body 13, the front ends (plate thickness portion) of the projection portions 95 abut on the stopper portions 112 of the outer shell body 13 (see FIG. 7), and an operation of further inserting the outer conductor tube 15 is restricted. The projection portions 95 bring the contact protrusion portions 117 into firm contact with the restriction portions 113 while remaining in an elastically deformed state (see FIG. 6). The outer conductor tube 15 is attached to the outer shell body 13 in a state where shakiness is restricted, due to locking action of the projection portions 95 on the outer shell body 13 and later-described holding action of the press-fitting blades 118 and the holding protrusion portions 121.
In the first embodiment, the outer conductor tube 15 is attached to the outer shell body 13 from behind, and thus it is possible to easily form a structure in which the stopper portions 112 restrict the outer conductor tube 15 coming loose forward. In particular, a direction in which the outer conductor tubes 15 are inserted into the outer shell body 13, a direction in which the inner conductors 11 and 12 are inserted into the dielectric bodies 16 and 17, a direction in which the dielectric bodies 16 and 17 are inserted into the outer conductor tubes 15, and a direction in which the outer shell body 13 is coupled to the housing 18, as will be described later, are all the same, that is to say a direction from the rear to the front, and thus the ease of attachment excels.
In addition, in a state where the tubular connection portions 94 are properly inserted into the through holes 46 of the outer shell body 13, the press-fitting blades 118 of the outer conductor tubes 15 are locked on right and left end sections of the inner peripheral surfaces of the through holes 46 of the outer shell body 13 so as to bite thereinto (compressed or crushed state) in a press-in state (see FIG. 3). In addition, the holding protrusion portions 121 of the outer conductor tubes 15 come into firm contact with upper, lower, right, and left sections of the inner peripheral surfaces of the through holes 46 of the outer shell body 13, on the rear side relative to the locking positions of the press-fitting blades 118 (see FIG. 4).
As shown in FIG. 11, front end portions of the tubular connection portions 94 protrude forward from the tubular portions 42 of the outer shell body 13. Assuming that the holding protrusion portions 121 are not formed on the tubular connection portions 94, and external force acts on the front end portions of the tubular connection portions 94 from above or from below, there is a concern that the tubular connection portions 94 will be pressed in an external force direction, and the axial centers of the tubular connection portions 94 will be displaced. With this regard, in the first embodiment, in addition to the press-fitting blades 118, a plurality of holding protrusion portions 121 are formed on each tubular connection portion 94, and the holding protrusion portions 121 are arranged at intervals in the circumferential direction, at upper, lower, right, and left sections of the tubular connection portion 94. In addition, the holding protrusion portions 121 come into contact with the inner peripheral surfaces of the through holes 46 of the outer shell body 13, and are held thereon, and thus it is possible to resist external force from above or from below, and to prevent the axial centers of the tubular connection portions 94 from being displaced.
Subsequently, the outer shell body 13 is coupled to the housing 18 from behind (see FIG. 11). In a process of coupling the outer shell body 13, the first coupling protrusion portions 43 move beyond the first locking protrusions 28, and are fitted into the fitting holes 27. When coupling of the outer shell body 13 is completed, the tubular portions 42 come into contact with farther surface of the recessed fitting portion 23, an operation of coupling the outer shell body 13 is stopped, and the rear surfaces of the first coupling protrusion portions 43 and the front surfaces of the first locking protrusions 28 come into contact with each other (see FIG. 2).
The front end portions of the tubular connection portion 94 are inserted into the insertion holes 22 of the housing 18 from behind. In the insertion holes 22, the housing-side holding protrusion portions 108 come into contact with the outer peripheral surface of front portions of the tubular connection portions 94 in a compressed or crushed state (see FIG. 5). The housing-side holding protrusion portions 108 come into contact with the outer peripheral surfaces of the tubular connection portions 94 from the upper, lower, right, and left sides. Accordingly, the tubular connection portions 94 are held on the outer shell body 13 using the press-fitting blades 118 and the holding protrusion portions 121, and, in addition, are held on the housing 18 using the housing-side holding protrusion portions 108 positioned on the opposite side to the holding protrusion portions 121 (on the front side) with the press-fitting blades 118 therebetween. Thus, in the first embodiment, it is possible to more reliably prevent the axial centers of the tubular connection portions 94 from being displaced. As a result, it is possible to realize a state where the axial centers of the tubular connection portions 94 match the axial centers of partner outer conductors 311 (see FIG. 2).
Next, the substrate-side outer shell body 14 is attached to the outer shell body 13 from below (see FIG. 12). At the end of a process of attaching the substrate-side outer shell body 14, the protrusion portions 72 interfere with the side portions 38, and the side portions 38 elastically deform outward in the width direction using the upper portion 37 side as a support, in a greater or lesser degree. When attachment of the substrate-side outer shell body 14 is completed, the engaging protrusion portion 47 of the outer shell body 13 comes into contact with the bottom surface of the groove portion 52 of the substrate-side outer shell body 14, or the like, an operation of attaching the substrate-side outer shell body 14 is stopped, restoring force acts on the side portions 38, and the protrusion portions 72 are fitted into the recessed portions 56 (see FIG. 9). Here, a lap margin is set between the protrusion portions 72 and the recessed portions 56, and thus the protrusion portions 72 come into contact with the inner surfaces of the recessed portions 56, and the contact state can be maintained. A state where the protrusion portions 72 are fitted into the recessed portions 56 is visually recognizable in rear view.
In addition, when attachment of the substrate-side outer shell body 14 is completed, the press-fitting protrusion portion 75 is fitted into the recessed press-fitting portion 45 from below, and the contact ribs 68 of the press-fitting protrusion portion 75 come into contact with the inner surface on the opening side of the recessed press-fitting portion 45 in a compressed or crushed state. For this reason, the substrate-side outer shell body 14 is stably held in a state where inclination of the substrate-side outer shell body 14 with respect to the outer shell body 13 in the front-rear direction is restricted.
In addition, when attachment of the substrate-side outer shell body 14 is completed, the second coupling protrusion portions 76 are fitted into the fitting grooves 34 of the housing 18 (see FIG. 13), the pressing ribs 78 of the second coupling protrusion portions 76 come into contact with the front surfaces of the second locking protrusions 32, and the second coupling protrusion portions 76 are held on the housing 18 in a retained state.
Furthermore, when attachment of the substrate-side outer shell body 14 is completed, the back portion 61, the standing portion 62, and the partition portion 63 are fitted into the fitting receiving portion 39 of the outer shell body 13, and the engaging protrusion portions 49 of the substrate-side outer shell body 14 are fitted into the groove portions 51 of the outer shell body 13 (see FIG. 9), and the engaging protrusion portion 47 of the outer shell body 13 is fitted into the groove portion 52 of the substrate-side outer shell body 14. The contact ribs 65 to 68 of the substrate-side outer shell body 14 come into contact with corresponding surfaces such as the inner surfaces of the groove portions 51 of the outer shell body 13 and the outer surfaces of the engaging protrusion portion 47, in a compressed or crushed state. Accordingly, between the outer shell body 13 and the substrate-side outer shell body 14, a large number of electrical connection structures (contact point structures) are formed via the contact ribs 65 to 68. For this reason, it is possible to improve the reliability of electrical connection between the outer shell body 13 and the substrate-side outer shell body 14.
The contact ribs 65 to 68 are in contact with the corresponding surfaces of the outer shell body 13 in the up-down direction. For this reason, assuming that vibrational force in the up-down direction acts on the outer shell body 13 and the substrate-side outer shell body 14, it is possible to maintain a contact state of the contact ribs 65 to 68. In particular, in the first embodiment, a large number of contact ribs 65 to 68 are formed on the inner surfaces of the groove portion 52 of the substrate-side outer shell body 14 and the outer surfaces of the engaging protrusion portions 49, the engaging protrusion portions 49 of the substrate-side outer shell body 14 are fitted into the groove portions 51 of the outer shell body 13, the engaging protrusion portion 47 of the outer shell body 13 is fitted into the groove portion 52 of the substrate-side outer shell body 14, and thus the contact ribs 65 to 68 can reliably come into contact with corresponding surfaces of the outer shell body 13.
In a state where the outer shell body 13 and the substrate-side outer shell body 14 are attached, as shown in FIG. 2, the standing portion 62 is disposed so as to cover, from behind, the outer conductor tubes 15 disposed in the through holes 46, the short dielectric bodes 16, and the short inner conductors 12. In addition, the back portion 61 is disposed to cover, from behind, the outer conductor tubes 15 disposed in the upper through holes 46, the long dielectric bodies 17, and the long inner conductors 11. The drawer portions 102 of the inner conductors 11 and 12 are entirely surrounded by the outer conductors 13, 14, and 15, except for the substrate connection portions 107. Accordingly, attachment of the shield connector 10 is completed.
Next, the shield connector 10 is installed on the surface of the circuit substrate 200 (see FIGS. 2 and 8 to 10). The substrate connection portions 107 of the inner conductors 11 and 12 are inserted into the connection holes 202 of the circuit substrate 200, the leg portions 54 of the outer shell body 13 are inserted into the fixed holes 201 of the circuit substrate 200, and the mount portions 84 to 87 are placed on the lands of conductive portions of the circuit substrate 200. As a result of reflow-soldering being performed in this state, the substrate connection portions 107 of the inner conductors 11 and 12 are connected to conductive sections for signals, in the connection holes 202 of the circuit substrate 200, through soldering. In addition, the leg portions 54 are fixed to the fixed holes 201 through soldering, and the mount portions 84 to 87 are connected to conductive portions for the ground through soldering.
The inner conductors 11 and 12 are surrounded by the plurality of mount portions 84 to 87, on the bottom surface 92 of the substrate-side outer shell body 14. For this reason, crosstalk between the inner conductors 11 and 12 adjacent to each other in the width direction and the front-rear direction is suppressed. In addition, the recessed regression portion 88 that is recessed so as to separate away from the surface layer wiring of the circuit substrate 200 is formed in the substrate-side outer shell body 14, and thus it is possible to prevent the substrate-side outer shell body 14 from being electromagnetically coupled to the surface layer wiring.
Incidentally, when reflow-soldering is performed, reflow heat is transmitted from the outer surface of the substrate-side outer shell body 14 to the mount portions 84 to 87, and solder (paste solder) corresponding to the mount portions 84 to 87 is melted. In the first embodiment, in the substrate-side outer shell body 14, the depressed portion 91 is provided extending from the back surface 93 of the back portion 61 to the bottom surface 92, and the thickness of the partition portion 63 is reduced, and thus it is possible to reduce heat conductivity resistance, realizing high heat conductivity to the mount portions 84 to 87. In particular, the depressed portion 91 extends to the vicinity of the lateral mount portions 85 of the bottom surface 92 of the substrate-side outer shell body 14, and thus it is possible to effectively prevent the lateral mount portions 85 from entering a non-soldered state.
In addition, in the first embodiment, as shown in FIG. 10, a state where the lateral mount portions 85 are bonded to the conductive portions of the circuit substrate 200 through soldering (see the soldering fillet indicated by reference sign “b” in FIG. 10) can be confirmed through the opening of the back surface 93 of the depressed portion 91.
