Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to an electrical connector and electrical connector assembly that is easy to manufacture and helps save space. Background Technology

[0002] Chinese invention patent CN109831928B discloses a coaxial connector assembly, wherein the plug assembly includes: a housing holding an external contact; a dielectric retainer received in the external contact, the dielectric retainer having a mating section and a cable segment orthogonal to the mating section, the mating section having a front cavity extending along a mating axis, the cable segment having a cable cavity extending along a cable axis; a cable assembly received in the cable cavity of the dielectric retainer, the cable assembly having pin contacts configured to terminate at the end of a center conductor of the cable, the pin contacts having an end; and a center contact received in the front cavity of the dielectric retainer, the center contact having a base and A mating portion extending forward of the base, the base being located approximately at the intersection of the front cavity and the cable cavity within the dielectric retainer, the center contact having a deflectable pin beam extending from the base, configured to deflect outward when mating with the pin contact, the pin beam including folded portions extending from both sides of the base, the pin beam also including an extension extending from the folded portions to a mating interface of the pin beam, the extension being bent or angled relative to the folded portions; the pin beam having an open lead end at its distal end, the base and the pin beam being axially aligned to receive the pin contact, wherein the pin beam includes a groove with beam arms on both sides of the groove, the pin beam being bent at the beam arms.

[0003] In this technical solution, the special shape of the dielectric retainer in the plug assembly is used to achieve a 90-degree mating connection between the cable and the socket assembly. The dielectric retainer and the external contacts extend beyond the outer housing in the height direction to facilitate cable connection. The plug assembly structure of this solution is relatively complex, making manufacturing and assembly difficult. Furthermore, it requires a significant height in the height direction, placing high demands on space. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and to propose an electrical connector and electrical connector assembly that is easy to manufacture and helps to save space.

[0005] The technical solution adopted in this invention is as follows:

[0006] According to one aspect of the present invention, an electrical connector is provided that can be mounted on a mounting base. The electrical connector includes: a first mating assembly comprising a pair of connectors for mounting to the mounting base, a first metal shell inserted into the pair of connectors, an insulating base housed within the first metal shell, and a central conductive pin passing through the insulating base in a front-rear direction; and a second mating assembly comprising a second metal shell, an insulating shell housed within the second metal shell, and a conductive terminal fixed within the insulating shell; the conductive terminal comprising a base, two elastic contact arms extending from opposite sides of the base and bent toward each other, and a mating portion extending downward from the base; wherein the central conductive pin is inserted between the two elastic contact arms to establish a first electrical connection, and the first metal shell and the second metal shell are electrically connected together to establish a second electrical connection.

[0007] According to another aspect of the present invention, an electrical connector assembly is provided, comprising a mounting body and an electrical connector as described above mounted on the mounting body, wherein a receiving cavity having a downward opening is formed in the mounting body, a mounting hole communicating with the receiving cavity is provided at the front end of the mounting body, a mating part of the electrical connector is correspondingly mounted to the mounting hole, a first mating assembly extends forward from the mounting body, and a second mating assembly is at least partially received within the receiving cavity.

[0008] Compared with the prior art, the present invention has at least the following advantages: In the electrical connector of the present invention, the first mating component has a central conductive pin extending in the front-to-back direction, which allows a cable connector to mate in the front-to-back direction, while the downwardly extending mating portion of the second mating component allows a mating connector to mate in the vertical direction. The first and second mating components form a signal transmission path through the first and second electrical connections established between them. Correspondingly, the electrical connector realizes the conversion between different electrical interfaces with a 90-degree bend. It can have a smaller size in the height direction, saving space and solving the problem of large vertical space occupation in existing conventional structures. The first and second mating components are manufactured and assembled separately. The constituent components of each component are simple, easy to manufacture and assemble, and the manufacturing method is relatively simpler and the cost is relatively more advantageous.

It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0042] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0044] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] First embodiment:

[0046] First refer to Figures 1 to 6 The electrical connector assembly 1000 of this embodiment includes a mounting base 300 and an electrical connector 100 mounted on the mounting base 300. The electrical connector 100 is exemplarily a FAKRA connector, but in other embodiments it can be a connector with different interfaces such as HFM or Mate AX. The electrical connector assembly 1000 can be connected to a mating connector 5000 and a cable connector (not shown in the figure), respectively.

[0047] For ease of description, the mating direction between the electrical connector assembly 1000 and the mating connector 5000 is defined as the vertical direction, wherein the mating connector 5000 is located below the electrical connector 100; the mating direction between the electrical connector assembly 1000 and the cable connector is defined as the front-back direction, wherein the electrical connector assembly 1000 is located behind the cable connector.

[0048] See Figure 7 and Figure 8The mounting base 300 is generally a rectangular box structure, including a top wall 31, two side walls 32 perpendicular to the top wall 31 and opposite to each other, a rear end wall 33 connected to the rear end of the two side walls 32, and a front end wall 34 connected to the front end of the two side walls 32. The top wall 31, two side walls 32, rear end wall 33, and front end wall 34 enclose a receiving cavity 35 with a downward opening inside the mounting base 300. The front end wall 34 is provided with a mounting hole 341 communicating with the receiving cavity 35. In this embodiment, the mounting hole 341 is a rectangular through hole that penetrates the lower surface of the front end wall 34. Preferably, the front surface of the front end wall 34 also forms a limiting step 342 around the mounting hole 341. The lower surface of the top wall 31 is provided with a relief groove 311 to facilitate reducing the height. In this embodiment, the relief groove 311 communicates with the mounting hole 341.

[0049] Combination Figures 6 to 8 The electrical connector 100 includes a first mating component 1 extending in a front-to-back direction and a second mating component 2 extending generally in a vertical direction. The first mating component 1 and the second mating component 2 are connected together to form an electrical connection. The first mating component 1 is mounted to the mounting base 300 and extends forward from the mounting base 300 for mating with a cable connector. In this embodiment, the second mating component 2 is entirely housed within the receiving cavity 35 of the mounting base 300 and is used for mating with the mating connector 5000.

[0050] See Figure 3 , Figure 4 and Figure 9 The first docking assembly 1 includes a pair of connectors 11, a first metal shell 12 inserted into the connectors 11, an insulating base 13 housed within the first metal shell 12, and a central conductive pin 14 extending in the front-rear direction within the insulating base 13. The connectors 11, the first metal shell 12, the insulating base 13, and the central conductive pin 14 all extend in the front-rear direction. The connectors 11 are used for rearward mounting to the mounting base 300. Furthermore, a first waterproof sealing structure 15 is provided between the first metal shell 12 and the connectors 11, and a second waterproof sealing structure 16 is provided between the rear portion of the central conductive pin 14 and the first metal shell 12.

[0051] Main references Figure 4 and Figure 9 The connector 11 includes a connecting cylinder 111 extending in the front-rear direction, a mounting plate 112 vertically disposed at the rear end of the connecting cylinder 111, and a buckle 113 protruding outward from the connecting cylinder 111. The connector 11 is integrally formed and can be made of aluminum or plastic.

[0052] The docking cylinder 111 is cylindrical, with its inner cavity having a stepped shape with a larger inner diameter at the front end and a smaller inner diameter at the rear end. The inner cavity with a larger inner diameter at the front end forms a docking cavity 1111 for inserting a cable connector. When the cable connector is inserted, the latch 113 engages with a locking hole (not shown in the figure) on the cable connector to lock the cable connector in place.

[0053] The mounting plate 112 is used to fix to the front wall 34 of the mounting base 300. The mounting plate 112 covers the mounting hole 341 of the front wall 34, and the front surface of the mounting plate 112 is flush with the front surface of the front wall 34. A mating step 1121 is provided on the periphery of the mounting plate 112, which mates with the limiting step 342 of the front wall 34 to facilitate the installation and positioning of the mounting plate 112 and the front wall 34.

[0054] In this preferred embodiment, the rear end face of the mounting plate 112 is further provided with a groove 1122 for accommodating the first waterproof sealing structure 15.

[0055] Continue reading Figure 4 and Figure 9 The first metal shell 12 is a cylindrical shape extending back and forth, and preferably has a mounting flange 121 protruding outward from its outer periphery.

[0056] In this embodiment, the first metal shell 12 has a relatively long length. The first metal shell 12 is installed in the connector 11, abutting against the inner wall of the rear end of the docking cylinder 111. The mounting flange 121 is positioned relative to the mounting plate 112, and the front end of the first metal shell 12 extends out of the docking cavity 1111. The rear end of the first metal shell 12 extends rearward beyond the connector 11.

[0057] Still refer to Figure 4 and Figure 9 The insulating base 13 is generally cylindrical in shape and is adapted to be housed within the first metal shell 12. The length of the insulating base 13 is less than the length of the first metal shell 12. The front end of the insulating base 13 is basically flush with the front end of the first metal shell 12, while the rear end of the insulating base 13 is spaced from the rear end of the first metal shell 12.

[0058] The central conductive pin 14 is an integral needle-shaped structure that passes through the center of the insulating base 13 in the front-to-back direction. The middle part of the central conductive pin 14 is fixed to the insulating base 13, the front end of the central conductive pin 14 is used to mate with the cable connector, and the rear end of the central conductive pin 14 extends backward beyond the first metal shell 12.

[0059] Main references Figure 4The first waterproof sealing structure 15 is housed in the groove 1122 of the connector 11 and is attached to the rear end of the mounting flange 121 of the first metal shell 12, thereby forming a waterproof seal between the first metal shell 12 and the connector 11.

[0060] The second waterproof sealing structure 16 is housed inside the first metal shell 12 and is attached to the rear end face of the insulating base 13. The second waterproof sealing structure 16 forms a waterproof sealing structure between the first metal shell 12 and the central conductive pin 14.

[0061] The first waterproof sealing structure 15 and the second waterproof sealing structure 16 can prevent external moisture from seeping in from the front end of the first docking assembly 1, thus achieving a waterproof function.

[0062] The first waterproof sealing structure 15 and the second waterproof sealing structure 16 can be formed by applying epoxy sealant to the corresponding positions. In addition to providing a waterproof sealing effect, they can also provide strong holding force and improve the bonding strength between the first metal shell 12 and the connector 11, the insulating seat 13, and the central conductive pin 14.

[0063] Combination Figure 3 , Figure 4 and Figure 10 The second docking assembly 2 includes a second metal shell 21, an insulating shell 22 installed inside the second metal shell 21, and a conductive terminal 23 fixed inside the insulating shell 22.

[0064] The second metal shell 21 includes a main body portion 211 extending in the vertical direction and a connecting portion 212 extending vertically forward from one side of the main body portion 211 at its center. The second metal shell 21 is preferably integrally formed.

[0065] The main body 211 is a cylindrical structure that is closed at the top and open at the bottom. The connecting part 212 is cylindrical, and its inner cavity is connected to the inner cavity of the main body 211. The connecting part 212 is for the first metal shell 12 of the first docking assembly 1 to be inserted into to form an electrical connection. The connecting part 212 is provided with a stop structure (not labeled in the figure) for limiting the insertion depth of the first metal shell 12.

[0066] In this embodiment, the connecting portion 212 has a shorter length than the main body portion 211. In other embodiments not shown, the connecting portion 212 may be replaced by a connecting hole formed on one side of the main body portion 211 for the first metal shell 12 to be inserted to form an electrical connection.

[0067] See Figure 10The insulating shell 22 is columnar, extending vertically, and has a slot 221 formed on its outer periphery in the middle. Multiple ribs 222 protrude from the outer periphery of the insulating shell 22; these ribs 222 can extend vertically as shown in the figure, or they can extend circumferentially. In this embodiment, the outer periphery of the insulating shell 22 also has a foolproof plane 223, which makes the insulating shell 22 form an asymmetrical structure, serving to prevent fooling and rotation during assembly.

[0068] like Figure 3 As shown, the insulating housing 22 is installed inside the main body 211 of the second metal shell 21, and the slot 221 of the insulating housing 22 faces the connecting portion 212. The top of the insulating housing 22 abuts against the main body 211, and the raised ribs 222 on the outer periphery of the insulating housing 22 contact the inner wall of the main body 211, increasing the friction between the insulating housing 22 and the main body 211, thereby making the insulating housing 22 more secure within the second metal shell 21.

[0069] See also Figure 10 The conductive terminal 23 includes a base 231, two elastic contact arms 232 extending forward from both sides of the base 231 and bending towards each other, and a mating portion 233 extending downward from the base 231. The conductive terminal 23 is preferably formed by stamping from a metal sheet.

[0070] In this embodiment, the base 231 has a ring-shaped sheet structure, and a receiving hole 2311 is provided in the middle of the base 231. The central axis of the receiving hole 2311 extends in the front-back direction.

[0071] The two elastic contact arms 232 extend perpendicularly from both sides of the base 231, and are opposite each other in the horizontal direction, and are 180 degrees apart along the circumference of the annular base 231.

[0072] Each elastic contact arm 232 includes a vertical extension 2321 vertically connected to the base 231 and an elastic contact portion 2322 extending backward from the front end of the vertical extension 2321, with the elastic contact portions 2322 of the two elastic contact arms 232 facing each other.

[0073] The docking portion 233 is connected to the base 231 via a connecting portion 235. The connecting portion 235 first extends vertically from the base 231 in the same direction as the vertical extension portion 2321 and extends forward for a certain distance, then extends vertically downward to form the docking portion 233. The length of the connecting portion 235 extending vertically forward is less than the length of the vertical extension portion 2321, thereby positioning the docking portion 233 at the center of the insulating housing 22. The docking portion 233 and the two elastic contact arms 232 are 90 degrees apart circumferentially on the annular base 231.

[0074] In this preferred embodiment, one side of the mating portion 233 is folded back and then overlapped onto the surface of the mating portion 233 to form a thickened mating portion 234, making the thickness of the mating portion 233 twice the thickness of the metal material. This not only improves the structural strength of the mating portion 233 but also enhances the contact force when mating with the mating connector 5000. In some possible embodiments, there may also be a gap between the thickened mating portion 234 and the mating portion 233, making the thickness of the mating portion 233 more than twice the thickness of the sheet material.

[0075] The conductive terminal 23 is held in place by the insulating housing 22. The upper and lower ends of the base 231 are joined together with the insulating housing 22. The receiving hole 2311 of the base 231 is aligned with the slot 221 of the insulating housing 22. The two elastic contact arms 232 are located on both sides of the slot 221 respectively. The mating portion 233 extends downward beyond the insulating housing 22.

[0076] Based on the above introduction, please refer to the main references. Figures 3 to 6 During assembly, the electrical connector assembly 1000 is first fabricated and assembled into the first mating component 1 and the second mating component 2, then connected together to form the electrical connector 100. Finally, the electrical connector 100 is installed onto the mounting base 300, fixing the mating head 11 of the first mating component 1 to the front end wall 34 of the mounting base 300. At this time, the second mating component 2 is entirely housed within the receiving cavity 35 of the mounting base 300, with the upper end of the second mating component 2 partially located within the clearance groove 311 of the mounting base 300. The clearance groove 311 increases the space of the receiving cavity 35, which helps to reduce the overall height of the mounting base 300.

[0077] See also Figure 5When the first docking assembly 1 and the second docking assembly 2 are connected, the rear end of the central conductive pin 14 of the first docking assembly 1 is inserted between the two elastic contact arms 232 of the conductive terminal 23 through the slot 221 of the insulating shell 22 of the second docking assembly 2. The central conductive pin 14 elastically contacts the elastic contact portion 2322 of the two elastic contact arms 232, thereby establishing a first electrical connection. The rear end of the first metal shell 12 of the first docking assembly 1 is inserted into the connecting portion 212 of the second metal shell 21 of the second docking assembly 2. The outer wall of the first metal shell 12 is attached to the inner wall of the connecting portion 212 and electrically connected together, thereby establishing a second electrical connection.

[0078] The first electrical connection and the second electrical connection form a signal transmission path for signal transmission between a cable connector that mates with the first mating component 1 and a mating connector 5000 that mates with the second mating component 2.

[0079] As described above, in this embodiment of the electrical connector 100, the first mating component 1 has a central conductive pin 14 extending in the front-to-back direction, which allows the cable connector to mate in the front-to-back direction. The second mating component 2 has a downwardly extending mating portion 233, which allows a mating connector 5000 to mate in the vertical direction. The first mating component 1 and the second mating component 2 form a signal transmission path through the first and second electrical connections established between them. Correspondingly, the electrical connector 100 achieves the conversion between different electrical interfaces with a 90-degree bend. It can have a smaller size in the height direction, saving space and solving the problem of large vertical space occupation in existing conventional structures. The first mating component 1 and the second mating component 2 are each manufactured and assembled separately. Each component has simple structural components, is easy to manufacture and assemble, and has a relatively simpler manufacturing method and a more cost-effective approach.

[0080] Meanwhile, for the electrical connector assembly 1000, the mating head 11 of the electrical connector 100 is installed onto the mounting base 300 in the front-to-back direction. The mounting base 300 and the mating head 11 are also manufactured separately and then assembled together. This design method can be applied to both aluminum and plastic materials, flexibly meeting the needs of different application scenarios and having better versatility.

[0081] Second embodiment:

[0082] See Figures 11 to 16 The preferred embodiment of the electrical connector assembly 1000a also includes a mounting base 300a and an electrical connector 100a mounted on the mounting base 300a. The electrical connector 100a includes a first mating component 1a and a second mating component 2a.

[0083] The main differences between this second embodiment and the first embodiment are: the structure of the front wall 34a of the mounting base 300a is different, the connection structure of the first mating component 1a and the second mating component 2a of the electrical connector 100a is different, and the setting positions of the first waterproof sealing structure 37a and the second waterproof sealing structure 16a are different.

[0084] like Figure 12 As shown, the front end wall 34a of the mounting base 300a has a mounting hole 341a for mounting the electrical connector 100a. In this embodiment, the mounting hole 341a is rectangular but does not penetrate the lower surface of the front end wall 34a. Similarly, a limiting step 342a provided on the front surface of the front end wall 34a around the mounting hole 341a does not penetrate the lower surface of the front end wall 34a.

[0085] See Figure 16 In the first docking assembly 1a, the insulating seat 13a is longer than the first metal shell 12a, and the rear end of the insulating seat 13a extends rearward beyond the first metal shell 12a. In the second docking assembly 2a, the second metal shell 21a includes a main body portion 211a extending in a vertical direction and a connecting portion 212a extending vertically forward from one side of the middle portion of the main body portion 211a. The connecting portion 212a has a length approximately equal to that of the main body portion 211a. A positioning flange 2121a protrudes from the outer periphery of the connecting portion 212a.

[0086] Combination Figure 13 , Figure 15 and Figure 16 The first docking component 1a and the second docking component 2a are docked in the front-rear direction. The connector 11a of the first docking component 1a is installed into the mounting hole 341a of the front wall 34a of the mounting base 300a. The main body of the second docking component 2a enters the interior of the mounting base 300a through the mounting hole 341a and is housed in the receiving cavity 35a.

[0087] The central conductive pin 14a of the first docking component 1a is electrically connected to the conductive terminal 23a of the second docking component 2a to establish a first electrical connection.

[0088] The connecting portion 212a of the second metal shell 21a of the second docking assembly 2a extends forward to the outside of the mounting base 300a and further extends into the docking connector 11a to connect with the first metal shell 12a. The front end of the connecting portion 212a is sleeved on the outer periphery of the first metal shell 12a. The connecting portion 212a and the first metal shell 12a are attached together to form an electrical connection, thereby establishing a second electrical connection.

[0089] The positioning flange 2121a of the connecting portion 212a is positioned and connected to the connector 11a. A first waterproof sealing structure 37a is provided between the connecting portion 212a and the mounting base 300a, and the first waterproof sealing structure 37a is attached to the rear side of the positioning flange 2121a and the connector 11a. The rear surface of the front end wall 34a of the mounting base 300a is provided with a groove 344a for receiving the first waterproof sealing structure 37a. The first waterproof sealing structure 37a forms a waterproof seal between the exterior of the second metal shell 21a and the mounting base 300a and the connector 11a, and also enhances the connection strength of the second metal shell 21a, the mounting base 300a and the connector 11a.

[0090] The insulating seat 13a of the first docking assembly 1a extends into the connecting portion 212a of the second metal shell 21a. The outer periphery of the insulating seat 13a fits against the inner wall of the connecting portion 212a. The second waterproof sealing structure 16a is provided around the central conductive pin 14a on the rear end face of the insulating seat 13a. The second waterproof sealing structure 16a and the inner wall of the connecting portion 212a form a waterproof sealing effect.
