Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to an electrical connector and an electrical connector assembly. Background Technology

[0002] An electrical connector is a key component used to connect electrical devices. Its core function is to transmit current, signals, or data, ensuring reliable communication and energy exchange between components. It typically consists of a plug, a socket, and internal conductors, establishing a conductive path through tight contacts and using insulating materials to isolate different circuits. Electrical connectors are widely used in electronic equipment, communication systems, industrial machinery, automotive electronics, and aerospace, possessing characteristics such as waterproofing, dustproofing, vibration resistance, and electromagnetic interference resistance to adapt to complex environments.

[0003] To facilitate the transmission of different electrical signals or currents, some existing electrical connectors typically include a first insulating shell and two types of conductive terminals. Due to the different signals being transmitted, one type of conductive terminal has a smaller overall width, while the other has a larger overall width. For the conductive terminal with a larger overall width, electrical conduction is achieved simply by elastically pressing it against the complementary terminal. However, for the conductive terminal with a smaller overall width, relying solely on elastic pressing can easily lead to unstable connections due to the small contact area. Even a slight external force can cause the complementary terminal and the conductive terminal to loosen. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides an electrical connector including a first insulating shell and a first terminal assembly inserted into the first insulating shell. The first terminal assembly includes a first conductive terminal, which includes a first retaining portion for insertion into the first insulating shell, a first mounting portion extending from the insertion portion away from the first retaining portion, and a clamping portion extending from the first retaining portion away from the first mounting portion and for clamping and engaging with a complementary object.

[0012] Furthermore, the first insulating shell has a first insertion cavity and a second insertion cavity along the insertion direction. The two ends of the first insertion cavity are respectively opposite to the first insulating shell to form a first insertion port and a second insertion port through which the first holding part and the clamping part pass. The two ends of the second insertion cavity are respectively opposite to the first insulating shell to form a third insertion port and a fourth insertion port through which the second insertion part and the mating part pass.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] Please see Figures 1 to 13 The present invention includes an electrical connector assembly including an electrical connector and a complementary electrical connector for electrically conducting with the electrical connector in a plug-in manner.

[0034] Please see Figures 1 to 10The present invention provides an electrical connector comprising a first insulating housing 1 made of insulating material, a grounding plate 2 inserted into the first insulating housing 1, and a first terminal assembly inserted into the first insulating housing 1. The first insulating housing 1 is used to protect the first terminal assembly and the grounding plate 2. The grounding plate 2 is used to stabilize voltage and current, ensuring the stability and reliability of the entire electrical connector. The first terminal assembly is used to conduct and connect with cables and complementary electrical connectors, thereby realizing the transmission of electrical signals.

[0035] Please see Figures 1 to 8 , Figures 11 to 13 In one embodiment, the first insulating housing 1 is integrally injection molded and is elongated. A insertion cavity is formed on the first insulating housing 1 along the insertion direction corresponding to the first terminal assembly (hereinafter referred to as the "insertion direction"). The two ends of the insertion cavity (i.e., the two sides of the insertion cavity along the insertion direction) are respectively opposite to the two sides penetrating the first insulating housing 1, so that a first socket and a second socket are formed on the two sides of the first insulating housing 1, respectively. The first socket is adapted to the first terminal assembly for the first terminal assembly to pass through so that the first terminal assembly is inserted into the insertion cavity. The second socket is adapted to the complementary electrical connector for the corresponding structure of the complementary electrical connector to pass through.

[0036] In another embodiment, the first insulating housing 1 includes a first housing 14 and a second housing 15, which are inserted and sleeved together to facilitate the processing and disassembly of the first insulating housing 1. Both the first housing 14 and the second housing 15 are elongated structures and are mutually compatible. The first housing 14 has a first surface 141 and a second surface 142 on its two sides along the insertion direction. A first cavity 143 is formed on the first surface 141 corresponding to the outer contour of the second housing 15, allowing the second housing 15 to be inserted along the insertion direction, facilitating the sleeve connection between the first housing 14 and the second housing 15. A built-in protrusion 144 protrudes from the inner wall of the first cavity 143 on the side closest to and opposite the second surface 142 along the insertion direction. The built-in protrusion 144 protrudes towards the first surface 141 along the insertion direction, and the end face of the built-in protrusion 144 away from the second surface 142 is recessed within the first cavity 143 relative to the first surface 141. A plurality of first guide protrusions 145 are arranged at intervals around the inner wall of the first cavity 143, and each first guide protrusion 145 is arranged along the insertion direction. In order to improve stability, two built-in protrusions 144 are provided and distributed at both ends along the longitudinal direction of the first housing 14, and the sides of the built-in protrusions 144 are spaced apart from the inner wall of the first cavity 143.

[0037] In this embodiment, the second housing 15 has a base 151 and an inner insertion portion 152 extending from the base 151 toward the first housing 14 in the insertion direction. The inner insertion portion 152 is consistent with and adapted to the shape of the first cavity 143 so that the inner insertion portion 152 can be inserted into the first cavity 143 in the insertion direction, thereby allowing the first housing 14 to be fitted onto the second housing 15. The side of the inner insertion portion 152 facing away from the base 151 is defined as a third surface 153, and the side of the base 151 facing away from the inner insertion portion 152 is defined as a fourth surface 154. Two second cavities 155 are recessed on the third surface 153 at positions corresponding to the built-in protrusion 144, so that when the inner insertion portion 152 is inserted into the first cavity 143, the built-in protrusion 144 is inserted into the second cavity 155, thereby improving the stability of the bonding force between the first housing 14 and the second housing 15. On the outer wall of the built-in protrusion 144, at the position corresponding to the first guide protrusion 145, a first guide groove 156 is recessed. The first guide groove 156 is open on the side away from the inner insertion part 152, and the first guide groove 156 is open along the insertion direction towards the first housing 14, that is, on the side away from the base 151, so that the first guide protrusion 145 and the first guide groove 156 slide in engagement during the process of the inner insertion part 152 being inserted into the first cavity 143.

[0038] In this embodiment, in order to better limit the insertion depth of the second housing 15, a stepped portion 157 is formed on the outer walls of both sides of the base 151, extending backward along the length direction of the second housing 15. The stepped portion 157 protrudes relative to the inner insertion portion 152, so that when the base 151 is inserted into the first cavity 143, the first housing 14 abuts against the stepped portion 157.

[0039] A first socket 12 communicating with the first cavity 143 is formed on the second surface 142 along the insertion direction. The first socket 12 is located between two built-in protrusions 144, which are spaced apart. A third socket 181 communicating with the second insertion cavity 17 is formed on the second surface 142, directly opposite the second insertion cavity 17, along the insertion direction. The third socket 181 is located on the periphery of the built-in protrusions 144 and is not affected by them. In this embodiment, the third sockets 181 are arranged in two groups corresponding to the built-in protrusions 144, with at least one third socket 181 in each group. Each group can be four in a rectangular array. Correspondingly, there are two built-in protrusions 144 and a total of eight third sockets 181. The first socket 12 and the third socket 181 are adapted to the complementary electrical connector so that the corresponding structure of the complementary electrical connector can pass through them. The first socket 12 is located between the two groups of third sockets 181.

[0040] A third cavity 182 is formed on the third surface 153 at a position corresponding to the first socket 12. The third cavity 182 extends through the third surface 153 along the insertion direction and extends through the fourth surface 154 along the insertion direction to form a second socket 13 on the fourth surface 154. When the first housing 14 and the second housing 15 are fitted together, the first socket 12, the third cavity 182, and the second socket 13 are arranged coaxially along the insertion direction, and the first housing 14, the second housing 15, and the third cavity 182 together form a first insertion cavity 11. The first socket 12 is used for the corresponding structure of the complementary electrical connector to pass through, and the second socket 13 is used for the corresponding structure of the first terminal assembly to pass through. To limit the insertion depth of the complementary electrical connector, a recessed structure 1441 is formed on each built-in protrusion 144 to create a second insertion cavity 17. This recessed structure 1441 has a retaining edge on the side near the fourth socket 183 along the insertion direction, making the recessed structure 1441 U-shaped and open towards the third socket 181. Two positioning protrusions 158 are provided on the side of the second housing 15 facing away from the first housing 14 along the insertion direction. These two positioning protrusions 158 are used to position the first insulating housing 1 when it is inserted into the circuit board or other connection structure for positioning.

[0041] A fourth socket 183 is provided on the fourth surface 154 at a position corresponding to the second cavity 155 along the insertion direction, and the fourth socket 183 communicates with the second cavity 155. The fourth socket 183 is adapted to the corresponding structure of the first terminal assembly, allowing the first terminal assembly to pass through. In this embodiment, a second insertion cavity 17 is formed by a recess between the built-in protrusion 144 and the inner wall of the second cavity 155, with a groove 1551 recessed on the inner wall of the second cavity 155 for each second insertion cavity 17. The groove 1551 extends through the third surface 153 along the insertion direction. The second insertion cavity 17 is jointly surrounded by the groove 1551 and the built-in protrusion 144, and the second insertion cavity 17 is directly opposite to and communicates with the third socket 181 and the fourth socket 183 along the insertion direction.

[0042] To facilitate the installation of the grounding piece 2, slots 16 are provided on the base 151 and on the stepped portions 157 on both sides, extending through the stepped portions 157 in the insertion direction. (See also...) Figure 13The grounding plate 2 has a wider portion 21 and a narrower portion 22. Corresponding to the wider portion 21 and the narrower portion 22, the slot 16 includes a wide slot 161 adapted to the wider portion 21 and a narrow slot 162 adapted to the narrower portion 22. The wide slot 161 and the narrow slot 162 face away from each other, with the wider portion 21 inserted into the wide slot 161 and the narrower slot 162 inserted into the narrower slot 162. A bent lug is formed on the side of the narrower portion 22 facing away from the wider portion 21 to abut against the stepped portion 157, facilitating connection to a circuit board or other connection structure. It should be noted that either the wider portion 21 or the narrower portion 22 can be any existing grounding plate 2.

[0043] Please see Figures 1 to 2 , Figure 8 , Figure 9 , Figures 11 to 13 The first terminal assembly of this utility model includes a first conductive terminal 3 inserted in a first insertion cavity 11 and a second conductive terminal 4 inserted in a second insertion cavity 17. The first conductive terminal 3 and the second conductive terminal 4 can be used to connect large current and small current respectively to realize different electrical signal transmissions.

[0044] Please refer to the figure. Figure 2 , Figure 8 , Figure 9 , Figures 11 to 13 In this embodiment, the first conductive terminal 3 includes a first holding portion 31 for insertion into the first insulating housing 1, a first mounting portion 32 extending from the insertion portion away from the first holding portion 31, and a clamping portion 33 extending from the first holding portion 31 away from the first mounting portion 32 and for clamping and engaging with a complementary object (i.e., the corresponding structure of the complementary electrical connector). The clamping portion 33 and the first holding portion 31 pass through the second socket 13 and are inserted into the first insertion cavity 11. The clamping portion 33 is used for clamping and engaging with the corresponding structure of the complementary electrical connector, and the first holding portion 31 is used for basic positioning when inserted into the first insertion cavity 11.

[0045] The first holding part 31, the first mounting part 32, and the clamping part 33 are all integrally formed and formed by stamping or other forming methods. Among them, the first holding part 31 has the largest size and the largest width relative to the first conductive terminal 3 in the width direction. In order to limit the insertion depth of the first holding part 31 to control the insertion depth of the mating part 43, a first protrusion 311 is provided on both sides of the second holding part 42 along the width direction. The first protrusion 311 is used to abut against the inner wall of the first insertion cavity 11 when inserted into the first insertion cavity 11. Due to the width difference, there is an L-shaped recess between the first holding part 31 and the clamping part 33. The first insertion cavity 11 includes a first cavity segment 111 and a second cavity segment 112 corresponding to the first holding part 31 and the clamping part 33, respectively. The first cavity segment 111 is close to and communicates with the second socket 13, and the second cavity segment 112 is close to and communicates with the first socket 12. The inner wall of the first cavity 111 is provided with a first groove 113 that is adapted to the first retaining part 31. The first groove 113 widens the first cavity 111 and forms a stepped structure between it and the inner wall of the second cavity 112. The two sides of the first retaining part 31 are inserted into the first groove 113. The L-shaped recess between the first retaining part 31 and the clamping part 33 cooperates with the stepped structure to limit the insertion depth of the first retaining part 31 and the entire first conductive terminal 3.

[0046] In this embodiment, the first mounting portion 32 extends along the insertion direction from the side of the first holding portion 31 facing away from the mating portion 43, then bends and continues to extend along the thickness direction to facilitate connection and mating with the connected object, or for welding, etc. In another embodiment, the first mounting portion 32 may extend in a straight line along the insertion direction away from the mating portion 43. One first mounting portion 32 may be provided; in another embodiment, two or more first mounting portions 32 may be spaced apart along the width direction. A clearance groove 312 extending to the first mounting portion 32 is provided on the first holding portion 31 to reduce hard interference between the first holding portion 31 and the first groove 113.

[0047] The clamping portion 33 includes a stabilizing section 33a connected to the first holding portion 31 and a clamping section 33b extending from the stabilizing section 33a away from the first holding portion 31 for clamping complementary objects. The stabilizing section 33a includes a first substrate 331 and a second substrate 332 connected to the first holding portion 31, and the first substrate 331 and the second substrate 332 are stacked. The second substrate 332 extends from one side of the first substrate 331 along the width direction and is bent to form a transition section at the end of the first substrate 331 connected to the first holding portion 31. The second substrate 332 can be spaced apart from and parallel to the first substrate 331, and the second substrate 332 can contact and be parallel to the first substrate 331. The clamping section 33b includes an elastic section 333 connected to the first substrate 331 and the second substrate 332 and arched outward in the middle, and a clamping section 334 narrower than the elastic section 333 for clamping complementary objects. The elastic section 333 provides elastic support to the clamping section 334. Specifically, two elastic segments 333 extend from the side of the first substrate 331 and the second substrate 332 away from the first holding portion 31, respectively. The two elastic segments 333 extend backwards from the first holding portion and then bend in the opposite direction along the thickness direction. After bending, the two elastic segments 333 extend away from the first holding portion 31 and then extend towards each other along the thickness direction, so that the elastic segments 333 are arched outwards in the middle and tapered at both ends. A clamping segment 334 is connected to the end of the two elastic segments 333 away from the first holding portion. The two clamping segments 334 are curved inwards in the thickness direction and approach or contact each other. The ends of the two clamping segments 334 are far apart from each other and are used to guide the corresponding structure of the complementary electrical connector, allowing it to be clamped by the two clamping segments 334 by pressing them. The elastic arm provides a supporting elastic force to the two clamping segments 334. During installation, the first mounting part 32 is located outside the first insertion cavity 11, the first holding part 31 is located inside the first groove 113, and the clamping part 33 is located inside the second cavity section, with the clamping section 334 facing the first insertion port 12.

[0048] Please see Figure 1 , Figure 3 , Figure 8 , Figures 10 to 13 In this embodiment, the second conductive terminal 4 includes a second mounting portion 41, a second holding portion 42, and a mating portion 43 distributed sequentially along the insertion direction. The mating portion 43 and the second holding portion 42 can both pass through the fourth socket 183 to extend into the second insertion cavity 17. The second holding portion 42 is used to fasten with the second insertion cavity 17 to restrict the movement of the second conductive terminal 4. The second mounting portion 41 is used to solder to the circuit board or connect to other conductive materials to achieve electrical conduction. The second holding portion 42 is used to position and limit the first insulating shell 1. The mating portion 43 is used to elastically abut against the corresponding structure of the complementary electrical connector to achieve the transmission of electrical signals.

[0049] In this embodiment, the second mounting part 41, the second holding part 42, and the mating part 43 are all integrally formed and formed by stamping or other forming methods. The second holding part 42 has the largest dimension and the widest width in the width direction. A through hole 421 is formed through the second holding part 42 at its center along its thickness direction. To facilitate processing, a groove 1551 is formed on the side of the through hole 421, and the shape of the corresponding punch is adapted to it to enhance the punch's strength. To limit the insertion depth of the second holding part 42 and control the insertion depth of the mating part 43, a second protrusion 423 is provided on both sides of the second holding part 42 along its width direction near the mating part 43. The second protrusion 423 is used to abut against the inner wall of the second insertion cavity 17 when inserted into it. The two sides of the second retaining portion 42 along the width direction are widened relative to the mating portion 43, forming an L-shaped notch 422 between the two sides of the second retaining portion 42. To ensure the fit between the second retaining portion 42 and the second insertion cavity 17, the second insertion cavity 17 includes a third cavity segment 171 and a fourth cavity segment 172 corresponding to the second retaining portion 42 and the mating portion 43. The third cavity segment 171 is close to and communicates with the fourth insertion port 183, and the fourth cavity segment 172 is close to and communicates with the third insertion port 181. A second groove 173 is recessed on the inner wall of the third cavity segment 171 corresponding to the two sides of the second retaining portion 42. The two second grooves 173 communicate with each other and open towards the fourth surface 154 along the insertion direction to form a part of the fourth insertion port 183. A stepped structure adapted to the L-shaped notch 422 is formed between the second groove 173 and the fourth cavity 172. Thus, when the two sides of the second retaining part 42 are inserted into the second groove 173, the convex bulge abuts against the inner wall of the second groove 173 until the stepped structure abuts against the L-shaped notch 422, thereby limiting the insertion depth of the second retaining part 42 and the mating part 43, so that the second retaining part 42 can no longer move toward the insertion cavity.

[0050] In this embodiment, the second mounting portion 41 extends from the side of the second retaining portion 42 opposite to the mating portion 43 along the insertion direction, then bends and continues to extend along the thickness direction to facilitate connection and mating with the connected object, or for welding, etc. In another embodiment, the second mounting portion 41 may extend in a straight line along the insertion direction opposite to the mating portion 43. The second mounting portion 41 may be a single unit; in yet another embodiment, the second mounting portion 41 may be two or more units spaced apart along the width direction.

[0051] In this embodiment, the mating part 43 includes a first elastic abutment part 43a and a second elastic abutment part 43b that is offset from the first elastic abutment part 43a. The first elastic abutment part 43a is used to elastically abut against the corresponding structure of the complementary electrical connector. The second elastic abutment part 43b is used to elastically abut against the corresponding structure of the complementary electrical connector and cooperates with the first elastic abutment part 43a to increase the holding force on the corresponding structure of the complementary electrical connector, thereby improving stability and the conductivity reliability of the corresponding structure of the complementary electrical connector. Furthermore, the first elastic abutment part 43a and the second elastic abutment part 43b are respectively used for directional cooperation with the second retaining part 42 along the thickness direction to abut against the first insulating shell 1, thereby improving the connection reliability between the first terminal assembly, the corresponding structure of the complementary electrical connector, and the first insulating shell 1.

[0052] The first elastic abutment portion 43a and the second elastic abutment portion 43b are staggered to abut against the corresponding structure of the complementary electrical connector at different positions. The first elastic abutment portion 43a and the second elastic abutment portion 43b can be staggered in the insertion direction or in the width direction, but they remain flush in the thickness direction to jointly abut against the corresponding structure of the complementary electrical connector. The first elastic abutment portion 43a has a first abutment position 431 formed by bending for elastically abutting against the corresponding structure of the complementary electrical connector, and the second elastic abutment portion 43b has a second abutment position 432 formed by bending, staggered from the first abutment position 431, for elastically abutting against the corresponding structure of the complementary electrical connector. In this embodiment, the second elastic abutment portion 43b is integrally formed on the first elastic abutment portion 43a and faces the corresponding structure of the complementary electrical connector relative to the first elastic abutment portion 43a, thereby reducing the overall width of the first terminal assembly. In another embodiment, the first elastic abutment portion 43a and the second elastic abutment portion 43b can be distributed side-by-side in the width direction.

[0053] The first elastic support portion 43a includes a first section 433 extending from the side of the second holding portion 42 away from the mounting portion along the insertion direction and a second section 434 extending from the first section 433 toward the side away from the mounting portion. The side of the second section 434 away from the first section 433 is inclined in the thickness direction toward the built-in protrusion 144 on the corresponding side of the corresponding structure of the complementary electrical connector and is inclined relative to the first section 433. A first support position 431 is formed on the second section 434. The second section 434 is bent along the thickness direction at one end away from the first section 433, forming a first free section 435. The first free section 435 is generally arc-shaped. Therefore, the middle part of the first free section 435 is curved and arched towards the corresponding structure of the complementary electrical connector to form a first abutment position 431. In use, the side of the curved first free section 435 away from the first section 433 contacts the corresponding structure of the complementary electrical connector through the first abutment position 431 and presses the corresponding structure of the complementary electrical connector against the built-in protrusion 144.

[0054] The second elastic abutment portion 43b includes a third section 436 extending from the first section 433 along the insertion direction toward the side away from the second mounting portion 41, and a fourth section 437 extending from the third section 436 toward the side away from the second mounting portion 41. A second abutment position 432 is formed on the fourth section 437. Specifically, in order to facilitate the integral forming of the second elastic abutment portion 43b and the first elastic abutment portion 43a, a cavity 438 is formed at the middle position of the first elastic abutment portion 43a, which extends toward the corresponding structure side of the complementary electrical connector. The cavity 438 extends from the first section 433 to the second section 434 and then to near the first free section 435 but does not extend to the first free section 435. The cavity 438 extends through the thickness direction of the first terminal assembly. The second elastic abutment portion 43b is located within the cavity 438 and is integrally connected at one end to the side of the cavity 438 near the second retaining portion 42. A gap exists between the inner wall of the cavity 438 and the second elastic abutment portion 43b, allowing the second elastic abutment portion 43b to independently engage with the corresponding structure of the complementary electrical connector relative to the first elastic abutment portion 43a, thereby achieving dual limiting and conduction with the corresponding structure of the complementary electrical connector. The fourth segment 437 has a second free segment 4391 at its end away from the third segment 436. The middle of the second free segment 4391 is curved upwards towards the corresponding structure of the complementary electrical connector, forming at least two curved segments 4392. One of these curved segments 4392, away from the third segment 436, is configured as the second abutment position 432. The arrangement of the second free segment 4391 and the second abutment position 432 is similar to or the same as the arrangement of the first free segment 435 and the first abutment position 431, and will not be described further here. It should be noted that the second conductive terminal 4 is wider than the first conductive terminal 3. Correspondingly, the second insertion cavity 17 is wider than the first insertion cavity 11. The first insertion cavities 11 are arranged as a group, and a group is provided with at least one first insertion cavity 11. Each first insertion cavity 11 corresponds to a first socket 12 and a second socket 13.

[0055] Please see Figures 11 to 13 In this embodiment, the complementary electrical connector includes a second insulating housing 5 and a second terminal assembly that is inserted into the second insulating housing 5 and extends out of the second insulating housing 5 along the insertion direction for mating with the first terminal assembly. The second insulating housing 5 is made of insulating material and has a cuboid structure. A fifth socket 51 and a sixth socket 52 are provided on the second insulating housing 5 at positions corresponding to the first socket 12 and the third socket 181, respectively, along the insertion direction. Two sets of fifth sockets 51 are directly opposite the first socket 12, and one set of sixth sockets 52 is directly opposite the third socket 181. Both the fifth sockets 51 and the sixth sockets 52 penetrate the second insulating housing 5 along the insertion direction.

[0056] The second terminal assembly includes a third conductive terminal 6 and a fourth conductive terminal 7. The third conductive terminal 6 is inserted into a fifth socket 51, and the fourth conductive terminal 7 is inserted into a sixth socket 52. The width of the third conductive terminal 6 is smaller than that of the fourth conductive terminal 7. The third conductive terminal 6 is the corresponding structure of the complementary electrical connector of the first conductive terminal 3, and the fourth conductive terminal 7 is the corresponding structure of the complementary electrical connector of the second conductive terminal 4.

[0057] In this embodiment, the third conductive terminal 6 includes a first insertion portion 61, a third holding portion 62, a first extension portion 63, and a third mounting portion 64. The first insertion portion 61 is narrower than the first socket 12 and can freely pass through the first socket 12, engaging with the clamping section 334 to be inserted between the two elastic sections 333. The third holding portion 62 extends from the first insertion portion 61 along the insertion direction. Third protrusions 621 are provided on both sides of the third holding portion 62 along its width. The third protrusions 621 are adapted to the first socket 12, and when the third holding portion 62 is inserted into the first socket 12, they abut against the first socket 12, thereby limiting the stability of the fit between the third conductive terminal 6 and the first insulating housing 1. The first extension portion 63 extends from the end of the third holding portion 62 away from the first insertion portion 61 along the insertion direction, and the width of the first extension portion 63 is narrower than the width of the third holding portion 62. The length of the first extension portion 63 can be adjusted according to the overall height of the electrical connector assembly. The third mounting portion 64 extends from the end of the first extension 63 away from the third retaining portion 62 along the insertion direction, and the width of the third mounting portion 64 is narrower than the width of the first extension 63. The fifth socket 51 is adapted to the third mounting portion 64 so that the third mounting portion 64 can pass through, while the first extension 63 cannot pass through the fifth socket 51, preventing the second insulating housing 5 from detaching from the third conductive terminal 6. After the third mounting portion 64 passes through the fifth socket 51, the end of the third mounting portion 64 away from the first extension 63 is bent and extends along the thickness direction to form a bent section a. A support edge is provided on the side of the second insulating housing 5, and the bent section a of the third mounting portion 64 is supported on the support edge. The bent section a is used to connect to the circuit board or other electrical components.

[0058] The fourth conductive terminal 7 includes a second insertion portion 71, a fourth holding portion 72, a second extension portion 73, and a fourth mounting portion 74. The second insertion portion 71 is narrower than the third socket 181 and can freely pass through the third socket 181. It is pressed against the inner wall of the second insertion cavity 17 by the first abutment position 431 and the second abutment position 432 of the mating portion 43. The fourth holding portion 72 extends from the second insertion portion 71 along the insertion direction. A fourth protrusion 721 is provided on both sides of the fourth holding portion 72 along its width. The fourth protrusion 721 is adapted to the third socket 181 and is pressed against the third socket 181 when the fourth holding portion 72 is inserted into the third socket 181, thereby limiting the mating stability between the fourth conductive terminal 7 and the first insulating housing 1. The second extension 73 extends from the end of the fourth retaining portion 72 away from the second insertion portion 71 along the insertion direction, and the width of the second extension 73 is narrower than the width of the fourth retaining portion 72. The length of the second extension 73 can be adjusted according to the overall height of the electrical connector assembly. Each fourth retaining portion 72 has at least one symmetrically distributed second extension 73 on one side away from the second insertion portion 71. In this embodiment, two second extensions 73 are provided to improve the connection between the fourth conductive terminal 7 and the second insulating housing 5. The fourth mounting portion 74 is provided corresponding to the second extension 73. Each second extension 73 extends from the end of the second extension 73 away from the fourth retaining portion 72 along the insertion direction, and the sixth socket 52 is adapted to the fourth mounting portion 74 so that the fourth mounting portion 74 can pass through. After the fourth mounting part 74 passes through the sixth socket 52, the end of the fourth mounting part 74 away from the second extension part 73 is bent and extended along the thickness direction to form a bent section a. The bent section a of the fourth mounting part 74 is still supported on the support side, so that the third mounting part 64 and the fourth mounting part 74 can be used to transmit large and small currents respectively.

[0059] The working method of the electrical connector and electrical connector assembly of this utility model is as follows: After the first housing 14 and the second housing 15 are installed, the clamping part 33 is oriented towards the second socket 13 and then passed through the second socket 13 along the insertion direction until the clamping part 33 and the first retaining part 31 are both inserted into the first insertion cavity 11. The first retaining part 31 is tightly fitted into the first groove 113 of the first insertion cavity 11, completing the installation of the first conductive terminal 3; the mating part 43 is oriented towards the fourth socket 183 and then passed through the fourth socket 183 along the insertion direction until the mating part 43 is inserted into the second insertion cavity 17 and the second retaining part 42 is inserted into the second groove 173, completing the installation of the second conductive terminal 4; initially, the third mounting part 64 and the fourth mounting part 74 are both in a straight line along the insertion direction. When the third mounting part 64 passes through the fifth socket 51 and the fourth mounting part 74 passes through the sixth socket 52, the... Do not bend the third mounting portion 64 and the fourth mounting portion 74 to form the bent section a; after aligning the first insertion portion 61 with the first socket 12 and the second insertion portion 71 with the third socket 181, move the third conductive terminal 6 and the fourth conductive terminal 7 along the insertion direction so that the first insertion portion 61 passes through the first socket 12 and enters the first insertion cavity 11. Then, by squeezing the first free section 435 and the second free section 4391, until the first abutment position 431 and the second abutment position 432 are elastically pressed against the first insertion portion 61 by utilizing the elastic properties of the material of the first terminal assembly (such as copper), until the third retaining portion 62 is tightly fitted into the first socket 12; at the same time, after the second insertion portion 71 passes through the third socket 181 and enters the second insertion cavity 17, by squeezing the clamping section 334, the clamping section 334 clamps the second insertion portion 71 until the fourth retaining portion 72 is tightly fitted into the third socket 181.

[0060] Compared with the prior art, the electrical connector and electrical connector assembly of this utility model improve the connection stability between the first insulating shell 1, the second insulating shell 5, the first terminal assembly and the second terminal assembly, and enhance the mating stability and reliability.
