Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and more specifically, relates to a conductive terminal assembly and a connector. Background Technology

[0002] A prior art conductive wire terminal connector has a housing containing multiple conductive terminals for connecting cables. The housing's insertion end has at least one row of mating posts for mating with a board-end connector. The insertion portions of the conductive terminals are correspondingly arranged within each mating post for insertion by the board-end connector's insertion terminals. Each insertion portion is formed by a top surface, a bottom surface, and two side surfaces. The side surfaces of adjacent insertion portions in each row of conductive terminals are parallel and have a gap. Figure 1 and Figure 2 As shown, the insertion portion 3 of the conductive terminal has inwardly protruding contact portions 8 on its two sides 11, which are used to contact the insertion terminals on the board-end connector. However, when the spacing between the insertion terminals of the board-end connector is slightly different, the contact portions 8 are located on the sides 11 of the insertion portion 3, which can cause significant terminal deformation when inserting or removing the conductive wire connector, thus affecting the stability of the contact.

[0031] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] like Figure 3 and Figure 4 As shown, this utility model provides a conductive terminal assembly, including:

[0033] At least one row of first terminal blocks, each row of first terminal blocks includes a plurality of first conductive terminals 1 arranged side by side and spaced apart, each first conductive terminal 1 includes a wire clamp 2 and a plug-in portion 3, the wire clamp 2 is used to connect with the wire core of the first cable 4, the plug-in portion 3 is provided with a plug-in cavity 5, the top surface 6 and bottom surface 7 of the plurality of plug-in portions 3 in each first terminal block are respectively located in a first plane and a second plane, and the top surface 6 and bottom surface 7 of each plug-in portion 3 are respectively provided with a contact portion 8 protruding toward the plug-in cavity 5.

[0034] Specifically, to address the problem in the prior art where the contact portion 8 of the conductive terminal is located on the two sides 11 of its insertion portion 3, which easily leads to significant terminal deformation during insertion and affects contact stability, the conductive terminal assembly provided by this utility model has multiple first conductive terminals 1 in each row of the first terminal block having their contact portions 8 located on the top surface 6 and bottom surface 7 of the insertion portion 3. This effectively reduces the significant terminal deformation caused by the difference in spacing between the insertion terminals on the board-end connector during insertion, thereby improving the stability of contact during insertion.

[0035] In this embodiment, the first terminal block is provided in two rows, and each row of the first terminal block is connected to a row of first cables 4.

[0036] Optionally, the wire clamp 2 includes an arc-shaped plate and two clamping plates disposed on both sides of the arc-shaped plate. The ends of the two clamping plates away from the arc-shaped plate form openings. The two clamping plates can be bent into the openings and clamp the wire cores. The openings face the direction of the top surface 6 or the bottom surface 7 of the plug-in portion 8.

[0037] Specifically, the two clamping plates of the wire clamp 2 are located on the two sides of the plug-in part 3, while the two contact parts 8 are located on the top surface 6 and the bottom surface 7 of the plug-in part 3, respectively.

[0038] In this embodiment, the opening faces the direction of the top surface 6 of the insertion part 8.

[0039] Optionally, the first conductive terminal 1 further includes a transition connection portion 9, which is connected between the wire clamp portion 2 and the plug portion 3.

[0040] Specifically, such as Figure 5 As shown, each first conductive terminal 1 is integrally connected between the wire clamp 2 and the plug-in part 3 through a transition connection part 9. A riveting area is formed in the wire clamp 2 for conductive connection between the first conductive terminal 1 and the wire core of the cable. The plug-in part 3 allows the plug-in terminal of the board end connector to be inserted through the setting of its plug-in cavity 5.

[0041] In this embodiment, one end of the transition connection 9 is connected to the bottom surface 7 of the insertion part 3, and the arc plate is connected to the other end of the transition connection 9.

[0042] Optionally, a conductive connecting piece 10 is provided on one side of each row of first terminal blocks, and the conductive connecting piece 10 is connected to a plurality of transition connecting parts 9 in the first terminal block.

[0043] Specifically, the transition connection part 9 provides conductive connection piece 10 to conduction connection with multiple first conductive terminals 1 in each row of first terminal blocks. The provision of conductive connection piece 10 can increase the current resistance performance of multiple first conductive terminals 1 in the first terminal block and improve the current shunting performance.

[0044] Optionally, the transition connection 9 is flat, and the conductive connecting piece 10 is wall-shaped, and is connected to the transition connection 9 through its trough portion.

[0045] Specifically, each trough of the wall-shaped conductive connecting piece 10 is connected to a flat transition connecting part 9 of a first conductive terminal 1, so that adjacent first conductive terminals 1 are connected together through the conductive connecting piece 10.

[0046] Optionally, the plug-in portion 3 includes a bottom surface 7, a top surface 6, and two side surfaces 11. The end of the plug-in portion 3 away from the wire clamp portion 2 has through slots 12 on the two side surfaces 11.

[0047] Specifically, the through slots 12 arranged opposite to each other on the two sides 11 can weaken the structural strength of the front side wall of the insertion cavity 5, making the conductive terminal assembly easy to insert and remove.

[0048] Optionally, a notch 13 is provided on one side wall of the through groove 12 near the bottom of the groove, and the notch 13 communicates with the through groove 12.

[0049] Specifically, the notch 13 facilitates the molding of the first conductive terminal 1.

[0050] Optionally, the end of the plug-in portion 3 near the wire clamp portion 2 is provided with a protruding stop portion 14 on both sides 11 facing the top surface 6.

[0051] Specifically, the protruding stop portion 14 allows the first conductive terminal 1 to better fit with the housing or injection molded body 15, restricting the first conductive terminal 1 and improving the installation stability of the first conductive terminal 1.

[0052] Optionally, it also includes an injection-molded body 15 that encloses at least a portion of the first cable 4 and at least a portion of the clamp portion 2 of each row of first terminal blocks.

[0053] Specifically, the connection between the first cable 4 and the first conductive terminal 1 is wrapped by an injection-molded body 15.

[0054] In this embodiment, each row of first terminal blocks is provided with an injection molded body 15.

[0055] like Figure 6 and Figure 7 As shown, the present invention also provides a connector including the above-described conductive terminal assembly.

[0056] Specifically, the connector is equipped with the aforementioned conductive terminal assembly. By setting the contact portion 8 of the first conductive terminal 1 in each row of the first terminal block on the top surface 6 and bottom surface 7 of its insertion portion 3, the relatively obvious terminal deformation caused by the difference in the spacing of the insertion terminals on the board-end connector is effectively weakened when it is inserted with the board-end connector, thereby improving the stability of the contact during insertion.

[0057] Optionally, the system also includes a housing, which includes a base 16 and a plurality of mating posts 17 disposed at the bottom of the base 16. Each mating post 17 is provided with a first conductive terminal 1, and the wire clamp portion 2 of the first conductive terminal 1 is disposed within the base 16.

[0058] Specifically, multiple mating posts 17 at the bottom of the base 16 are also arranged in a row, corresponding to the first terminal block, for insertion with the board connector. The first conductive terminal 1 in the mating post 17 is connected to the insertion terminal of the board connector through the insertion part 3 at its front end.

[0059] Optionally, a latch is provided on one side of the base 16.

[0060] Specifically, the latch is used to engage with the board-end connector, improving stability after insertion.

[0061] Optionally, the latch includes a locking plate 18, the middle of which is connected to the base 16 via a connecting plate. The end of the locking plate 18 near the first cable 4 is inclined toward the side away from the housing and is connected to a pull strap 19. The end of the locking plate 18 away from the first cable 4 is provided with a snap-fit ​​part. A guide hole 20 is provided on one side of the base 16, and the pull strap 19 passes through the guide hole 20.

[0062] Specifically, the pull strap 19 facilitates the removal of the connector from the board-end connector. The pull strap 19 passes through the guide hole 20 and forms a fulcrum through the hole wall of the guide hole 20, changing the pulling direction of the pull strap 19 on the locking plate 18, making the pulling more convenient and effortless. When the pull strap 19 is pulled outward, it can drive the end of the locking plate 18 near the first cable 4 to move towards the base 16, thereby causing the end of the locking plate 18 away from the first cable 4 to move away from the base 16, thereby unlocking the snap-fit ​​part on the locking plate 18.

[0063] Optionally, a receiving groove is provided on the other side of the base 16, and a docking plate 21 is provided at the bottom of the base 16 corresponding to the receiving groove. A second terminal block is provided in the docking plate 21. The second terminal block includes a plurality of second conductive terminals arranged side by side and spaced apart. The second conductive terminals are connected to a second cable 22, and one end of the second cable 22 is located in the receiving groove.

[0064] Specifically, the second conductive terminal in the second terminal block can be different from the first conductive terminal 1 in the first terminal block, and is used for electrical connection of the second cable 22 with different current, thereby expanding the connection function of the connector.

[0065] In this embodiment, the second terminal block is provided in a row and connected to a row of second cables 22.

[0066] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
