Description
FIELD OF THE DISCLOSURE

The present invention relates to an electrical connector assembly, comprising two connectors which are pivotable with respect to each other in an assembled condition. The invention also pertains to the individual connectors of such an assembly, including a header connector, a receptacle connector and a hermaphroditic connector providing receptacle contacts as well as header contacts.


BACKGROUND OF THE DISCLOSURE

In many applications it is desirable to connect a circuit board with another component, such as a further circuit board or one or more cables, in such a way that the circuit board and the connected component are rotatable with respect to each other without interrupting the electrical and mechanical connection during such rotation. This is for instance desirable with connection LED strips.


Accordingly there is a need for a hingeable or pivotable connector assembly, particularly for board-to-board or board-to-cable application, enabling easy, reliable and releasable contacting of the header contacts and the receptacle contacts. It is a further object of the invention to provide a connector assembly allowing insertion of one or more header contacts into respective receptacle contacts from a plurality of mating directions.


SUMMARY OF THE DISCLOSURE

In a first aspect, an electrical connector assembly is provided comprising a first connector and a second connector which are pivotable with respect to each other about a main pivoting axis in an assembled condition. The first connector is provided with at least one header contact blade and the second connector has at least one receptacle contact blade for contacting the header contact blade and a receptacle housing with an entrance for insertion of a header contact blade between a contact surface of the receptacle contact blade and an opposite surface facing the contact surface. The entrance is configured to allow insertion in an angular range of mating directions within a plane perpendicular to the main pivoting axis. At least part of the contact surface of the receptacle contact blade and the opposite surface converge towards the main pivoting axis over said angular range of mating directions. The receptacle contact blade has a free peripheral portion at the entrance of the receptacle housing, which is resiliently movable with respect to the receptacle housing at least in a direction parallel to the main pivoting axis.


Due to this feature the receptacle contact blade can be moved with respect to the receptacle housing upon entry of the header contact blade into the receiving member. This allows easy and effective insertion of the header contact, while avoiding internal stress within the receptacle housing particularly with an assembly according to claim 2.


Multidirectional accessibility is further improved with a double curved contact surface as provided with claim 3.


The surface opposite to the contact surface of the receptacle contact can be part of the same receptacle contact. This way, the respective header contact can be received between two resilient clamping blades of a same contact.


In a refinement, the assembly can be according to claim 5 providing symmetrical receptacle contacts.


In a specific embodiment the assembly can be according to claim 6, thus avoiding that the housing would limit the freedom of relative rotation of the two connectors.


The connectors of the assembly can for instance be hermaphroditic connectors, both provided with one or more header contacts and receptacle contacts. In that case, the first and second connector may have identical configurations, if so desired.


Alternatively, the first connector is a header connector provided with one or more header contacts while the second connector is a receptacle connector provided with one or more receptacle contacts.


In a further refinement, the assembly can be in accordance with claim 10. This allows easy and releasable mechanical coupling of the two connectors without restricting the freedom of rotation. Such an assembly can for example be configured in accordance with claim 11.


In a further aspect, an electrical connector assembly is disclosed, comprising a first connector and a second connector which are pivotable with respect to each other about a pivoting axis in an assembled condition, the first connector being provided with at least one header contact and the second connector having at least one receptacle contact with two opposite contact faces or blades receiving the header contact, wherein the receptacle contact faces and the header contact are provided with complementary spherical concave and convex surface sections in line with the pivoting axis. The spherical recesses can for instance be coined holes in the contact blades. When the two connectors are assembled the convex surface sections will guide themselves into the corresponding recesses. The retention forces mutually exerted by the contact blades are enhanced, while, on the other hand, pivoting is not hindered.


In a specific embodiment, the header contacts are each provided with a spherical concave recess, while the receptacle contacts are provided with a spherical convex surface.


If the spherical radius of the spherical counter surface is larger than the spherical radius of the recesses, a substantially ring shaped contact zone is obtained. This results in a larger contact area. Particularly in such a case accurate positioning results in a better contact. To this end, the first and second connectors can be joint by a latch of one connector cooperating with a counter surface on the mating connector, the latch and the counter surface being provided with complementary spherical recesses and bulges in line with the pivoting axis.


In an alternative embodiment, the spherical radius of the bulges can be made smaller than the spherical radius of the recesses. This results in a point contact. Although such a point contact requires less accurate positioning, it can also be combined with the aforementioned bulged latch joint.


In a further aspect, an electrical connector assembly is disclosed, comprising a first connector and a second connector which are pivotable with respect to each other about a main pivoting axis in an assembled condition, the first connector being provided with at least one header contact and the second connector having at least one receptacle contact. The contacts have a surface mounting end for connection to a circuit board and a mating end contacting a matching contact. The surface mounting ends of the first connector are positioned at a side opposite to the side of the second connector exposing the surface mount ends of the second connector. This way, circuit boards connected by the connector assembly are at a different level when positioned in a parallel orientation, being spaced by the connector assembly. This makes it possible to pivot a circuit board between a +90 degrees position and a −90 degrees position relative to the other circuit board.


In a further aspect, an electrical connector assembly is disclosed, comprising a first connector and a second connector which are pivotable with respect to each other about a main pivoting axis in an assembled condition, the first connector being provided with at least one header contact and the second connector having at least one receptacle contact. The contacts have a surface mounting end for connection to a circuit board and a mating end contacting a matching contact. The first and second connectors are provided with respective connector housings with a surface mount side exposing the surface mounting ends of the contacts, and a mating side exposing the mating ends of the contacts. The connector housings have a lower side provided with a ridge between the surface mount side and the mating side. The ridge increases the creep distance between the mating ends of the contacts one the one hand and the circuit board on the other.


In a specific embodiment, the first connector comprises at least one cylindrical surface with an axis parallel to the main pivoting axis, the cylindrical surface engaging a counter surface of the second connector during hinging. Optionally, the cylindrical surface and the counter surface are provided with complementary profiles, such as complementary ribs extending parallel to the hinging axis, to enable stepwise relative rotation of the connectors, e.g., as with a gearwheel.


Further, a receptacle contact is disclosed for being incorporated in a receptacle of the assembly as described hereinbefore and to a method of manufacturing such a receptacle contact. In the assembled condition of the receptacle connector, the two folding lines act as pivoting axis for resiliently pivoting of the contact blades. The freedom of pivoting movement is enhanced by having the two folding lines under an angle with each other.


The first connector of the connector assembly can be a header connector while the second connector is a receptacle connector. Alternatively, both connectors can be hermaphroditic connectors, e.g., showing identical configurations.


The header contacts and the receptacle contacts are made of an electro-conductive material.

DETAILED DESCRIPTION OF EMBODIMENTS


FIGS. 1-3 show an embodiment of an electrical connector assembly 1 in assembled condition according to the invention. The electrical connector assembly 1 comprises a first connector 2 which is a header connector mounted to a first printed circuit board 3 and a second connector 4 which is receptacle connector mounted to a second printed circuit board 5. The header 2 and the receptacle 4 are pivotable with respect to each other about a main pivoting axis 6. FIGS. 1-3 illustrate that the electrical connector assembly 1 allows to pivot the printed circuit boards 3, 5 with respect to each other, whereas the electrical and mechanical connections are maintained.



FIGS. 4A and 4B show two perspective views of an individual header connector 2 which is provided with electro-conductive header contact blades 7. The contact blades 7 are fixed in a header housing 8. The contact blades 7 comprise a semi-circular mating end 9, which is directed towards the pivoting axis 6 in assembled condition, and an opposite surface mount end 10, which can be surface mounted to a circuit board, for instance by soldering. The mating end 9 is under a right angle with the surface mount end 10. The header housing 8 is also provided with lateral terminal guiding surfaces 11 with inwardly spherical latching pegs 12.



FIGS. 5A and 5B show two perspective views of the receptacle connector 4 which comprises a receptacle housing 13 with a semi-circular mating side 14 with a centre line substantially coinciding with the main pivoting axis 6, and an opposite flat surface mount end 15. The semi-circular mating side 14 of the housing 13 is provided with circumferentially extending entrances 16 into which respective header contact blades 7 can be inserted to contact receptacle contacts 17. The entrances 16 are semi-circular slits centred about the central pivoting axis 6. Due to the semi-circular shape of the entrances 16, the header contact blades 7 can be inserted into the entrances 16 in any direction within an angular range α with respect to the main pivoting axis 6 within a plane substantially perpendicular to the pivoting axis 6, as shown in FIG. 6.


The side faces of the receptacle housing 13 are provided with latching holes 18 for receiving the latching pegs 12 of the header 2 to form a ball snap joint for mechanically attaching the two connectors 2, 4 without restricting the freedom of rotation about the main pivoting axis 6. A V-shaped guiding ledge 25 on the side surface serves to guide a latching peg towards the latching hole 18 during assembly.



FIG. 8 shows a perspective view of a receptacle contact 17 as a separate part. The receptacle contact 17 is symmetrical with respect to a plane extending transversely to the main pivoting axis 6, and comprises opposite contact blades 19 with opposite contact surfaces 20, 21 between which the corresponding header contact blade 7 is received in the assembled condition. The blades 19 have free peripheral portions 22 positioned at the entrance 16 in an assembled condition of the receptacle connector 4. The peripheral portions 22 are resiliently movable with respect to the receptacle housing 13 in a direction parallel to the main pivoting axis 6. This way the receptacle contact blades 19 are pivotable with respect to the receptacle housing 13 about a blade pivoting axes 24. The blade pivoting axes 24 extend transversely with respect to the main pivoting axis 6 and in this case the blade pivoting axes 24 are substantially parallel with each other. The contact surfaces 20, 21 of the contact blades 19 are double curved and are convex in radial and in circumferential direction relative to the main pivoting axis 6. This way, the two opposite contact surfaces 20, 21 of the receptacle contact 17 converge towards each other along the full run of the semi-circular entrances 10 and, consequently, over at least a sub-range of the angular range α of mating directions.


At the opposite end the receptacle contact 17 comprises a surface mount end 23 for mounting the receptacle connector 4 to a circuit board, for instance by soldering.


The receiving member 10 as shown in FIG. 8 can be made from a blank of an electro-conductive material, as illustrated in FIG. 9A-C. FIG. 9A shows a blank 30 having a base 31 and two substantially parallel legs 32 protruding from the base 31. The legs 32 are folded into U-shapes about a first folding line 33 which extends transversely with respect to the legs 32 (see FIG. 9B). In a next step the base 31 is folded about a second folding line 34 extending parallel to the legs 32 such that free end portions of the legs 32 form opposite blades 19. The two folding lines 33, 34 of the legs 32 form resilient hinges such that the opposite blades 19 are pivotally connected to the base 13. The resulting receptacle contact 17 as shown in FIG. 9C can be fixed into the receptacle housing 13. The end portions of the legs 14 can be made convex by bending the end portions before bending the legs 32 into U-shapes.



FIGS. 10 and 11 show a hermaphroditic connector 40 comprising a header contact 7 and a receptacle contact 17, both as described here above. The connector 40 can be connected to a connector of identical configuration to form a connector assembly 41, as shown in FIG. 12. FIG. 13 shows a series of LED strips 42 connected by means of such connector assemblies 41.



FIG. 14 shows a third embodiment of a connector assembly 50 comprising a header connector 51, shown in more detail in FIG. 15, and a receptacle connector 52, shown in more detail in FIG. 16. The connectors 51, 52 are similar to the header connector 2 and receptacle connector 4 of FIG. 1, with the difference that the header connector 51 comprises partitions 53 between each pair of contact blades 7, whereas the receptacle connector 52 comprises corresponding receiving spaces 54 for receiving the partitions 53 when the connector assembly 50 is in an assembled condition. The partitions 53 have a semi-circular end 55 at the mating side of the header connector 51 with a center in line with the main pivoting axis 6 to avoid restriction of freedom of rotational movement.



FIG. 17 shows two circuit boards 101, 102 connected by a pivotable connector assembly 103 comprising two mating identical hermaphroditic connectors 104. An example of such a connector is shown in more detail in FIG. 18, which is different from the connector in FIG. 17 in that it does not have a ridge 134 at its lower side, as will be discussed hereinafter with reference to FIG. 25. The connector 104 comprises a connector housing 105, with a mating side 106 with receptacle blocks 107 having a semi-cylindrical mating end 108. The distance between the receptacle blocks 107 corresponds to the width of the receptacle blocks 107. This way, the receptacle blocks 107 fit between the receptacle blocks 107 of a mating connector 104.


One of the ends of the connector comprises a terminal latch 109 with a contour following the semi-cylindrical contour of the receptacle blocks 107. On its side facing the closest receptacle block 107, the terminal latch 109 is provided with a spherical bulge 110. The receptacle block 107 at the opposite side comprises a recess 111 shaped to cooperate with the bulged terminal latch 109 of a mating connector 104 as a ball joint in a pivoting manner. The distance between the terminal latch 109 and the closest receptacle block 107 is the same as the distance between the receptacle blocks 107.


The connectors 104 further comprises header contacts 112 with a mating end 113 and a surface mount end 114 (see FIG. 20), and receptacle contacts 115 with a mating end 116 and a surface mount end 117 (see FIG. 19). The mating ends 112 of the header contacts 112 project from the connector housing in a position centrally between two receptacle blocks 107, the last header contact being between the terminal latch and the closest receptacle block 107. Both side faces of the header contacts 112 are provided with a spherical recess 118, which are in line with the spherical bulge 110 of the terminal latch 109 and with the recess 111 in the outer surface of the terminal receptacle block 107. The imaginary line through the spherical recesses and the bulge on the terminal latch forms a pivot axis 119 (see FIG. 4).


The receptacle blocks 107 are provided with a central slit 120 providing access for a header contact 112 of a mating connector 104 for engaging a respective receptacle contact 115.


The connector side opposite to the mating side 106 is a surface mount side 121 provided with indentations 122 exposing the surface mount ends 114, 117 of the header contacts 112 and the receptacle contacts 115 to enable surface mounting of the contacts 112, 115 onto a circuit board 101, 102, as shown in FIG. 17. Surface mounting can for instance take place by soldering, through hole soldering, press fit or any other suitable surface mount technique.



FIG. 19 shows a perspective view of a receptacle contact as a separate part. The receptacle contact 115 is symmetrical with respect to a plane extending transversely with respect to the main pivoting axis 119 (see FIG. 20), and comprises a mating end 116 with two contact blades 125, 126 providing opposite contact surfaces 127, 128 between which a corresponding header contact blade can be received. The contact surfaces 127, 128 of the contact blades 125, 126 are convex. This way, the two opposite contact surfaces 127, 128 of the receptacle contact 115 converge towards each other along the full periphery of the semi-circular slits 120 of the respective receptacle block 107. When mounted in a connector 104 the distance between the two opposite convex contact surfaces 127, 128 is smallest at the position of the pivoting axis 119. This way, the convex contact surfaces 127, 128 cooperate with the spherical recesses 118 in the header contacts 112 in a pivoting manner like a ball joint, as shown in FIG. 20.


At the opposite end the receptacle contact 115 comprises a surface mount end 117 for mounting the receptacle connector to a circuit board 101, 102, for instance by soldering.


Within dimensional tolerances the spherical radius of the convex contact surfaces 127, 128 of the receptacle contact 115 can be equal to the spherical radius of the spherical recess 118 of the header contacts 112. However, it can be advantageous to make the radius of the contact surfaces 127, 128 smaller (see FIG. 21) or larger (see FIG. 22) than the radius of the recesses 118. In the first case, a point contact 129 is obtained near or at the location of the pivoting axis 119. In such a case, accurate positioning is less critical. If the spherical radius of the convex contact surfaces 127, 128 is larger than the radius of the recess 118 in the header contact 112, a ring contact 130 is obtained. This has the advantage that a larger contact area can be realized. Such a large contact area can particularly be obtained by improving accurate positioning, for instance by use of the ball joint mechanism provided by the terminal latch 109 and the matching recess 111 in the outer surface of the cooperating receptacle block 107.



FIG. 23 shows an alternative embodiment of a connector 131, which is substantially identical to the connector shown in FIG. 18, with the difference that the header contacts 112 and receptacle contacts 115 are positioned upside down within the connector housing 105. Using a connector assembly combining such a connector 131 with a connector 104 of FIG. 18 makes it possible to connect a first circuit board at the lower side of the connector assembly 103 with a second circuit board 102 at the top side of the connector assembly. This is shown in FIG. 24B. This way, the second circuit board 102 can be moved between a +90 degrees position and a −90 degrees position relative to the first circuit board 101, as shown in FIGS. 24A and 24C respectively.



FIG. 25 shows in cross section a further embodiment of a connector 132, similar to the connector 104 of FIG. 18. The connector 132 is mounted on the edge of a circuit board 1. The housing 133 of this connector 132 comprises a ridge 134 between the surface mount ends 114, 117 of the contacts 112, 115 and the semi-cylindrical mating side 108 of the housing 133. The ridge 134 enhances the creep distance between the electroconductive parts 135 of the circuit board and the electroconductive parts 112, 115 of the mating end of the connector 132.



FIGS. 26A-C shows a further exemplary embodiment of a connector assembly 140 with a first connector 141 and a second connector 142 which are pivotable with respect to each other about a main pivoting axis 143 (see FIG. 26C) in an assembled condition. FIGS. 26A and 26B show the assembly 140 in perspective views from two opposite sides. FIG. 26C shows a cross section along line C-C in FIG. 26B. In this embodiment, the first and second connector 141, 142 are identical and interchangeable. As with the embodiment of FIG. 17, the first and second connectors 141, 142 are provided with header contacts 144 and receptacle contacts 145 receiving the header contacts 144. The connectors 141, 142 comprise a connector housing 146 with receptacle blocks 147 having a semi-cylindrical mating end 148. The distance between the receptacle blocks 147 corresponds to the width of the receptacle blocks 147. This way, the receptacle blocks 147 of the first connector 141 fit between the receptacle blocks 147 of the second connector 142 and vice versa.


In the embodiment of FIGS. 26A-C the semi-cylindrical ends 148 are provided with ribs 149 extending in a direction parallel to the main pivoting axis 143. In the assembled condition the ribbed semi-cylindrical ends 148 face a recessed surface 150 of the mating connector. The recessed surface 150 is provided with a single rib 151 (see FIG. 26C) dimensioned to cooperate with the ribs 149 of the ribbed semi-cylindrical end 148. This way, the two connectors 141, 142 can be rotated relative to each other in a stepwise manner and the connectors 141, 142 are biased to a limited number of relative positions.


The invention is not limited to the embodiment shown in the drawings and described hereinbefore, which may be varied in different manners within the scope of the claims.
