Description

Technical Field

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

[0002] The connection terminals allow current to flow between two components. Conventional connection terminals require a spring for connection. For example, after the pin is inserted, it first contacts the spring. Another conductive element is sleeved on the outside of the spring, which is connected to the base. The base is connected to the wire harness. It can be seen that after the pin is inserted, it needs to pass through the spring to conduct current with the conductive element. This increases the impedance of current conduction and affects its current conduction performance. Utility Model Content

The coil spring has an insertion hole opened along its axial direction, and the assembly passes through the insertion hole to the receiving groove to realize the connection between the coil spring and the connecting seat.

[0005] The end of the coil spring away from the connecting seat is provided with multiple slots. These slots are spaced apart to form multiple spring pieces. When the pin is inserted into the socket, the multiple spring pieces abut against the pin.

[0006] According to one embodiment of the present invention, the spring has an arc surface that protrudes toward the center of the insertion hole.

[0030] Example 1

[0031] like Figures 1-4 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting terminals; Figure 2 This is a split view of the connection terminals; Figure 3 This is a cross-sectional view of the connecting terminals; Figure 4 This is a three-dimensional structural diagram of the coil spring 2. The connecting terminal includes a connecting seat 1, a coil spring 2, and an assembly 3. The connecting seat 1 is connected to the wire harness. The coil spring 2 is detachably connected to the connecting seat 1 through the assembly 3. The pin is inserted into the coil spring 2, and current can be conducted between the pin, the coil spring 2, the connecting seat 1, and the wire harness.

[0032] Specifically, the connecting seat 1 has a receiving groove 11, one end of the coil spring 2 is disposed in the receiving groove 11, and the assembly 3 fixes the coil spring 2 and the connecting seat 1 in the receiving groove 11. In this embodiment, the assembly 3 is a bolt, and the bottom wall of the receiving groove 11 has a threaded hole, and the assembly 3 is screwed to the connecting seat 1.

[0033] The coil spring 2 has a socket 21, which is opened along the axial direction of the coil spring 2. One end of the assembly 3 is located in the socket 21, and the other end of the assembly 3 is connected to the connecting seat 1, thereby realizing the fixed connection between the coil spring 2 and the connecting seat 1. The end of the coil spring 2 away from the connecting seat 1 has a plurality of slots 22. The plurality of slots 22 are distributed at intervals around the periphery of the port of the coil spring 2. The opening of the plurality of slots 22 forms a structure of a plurality of spring pieces 23. When the pin is inserted into the socket 21, the plurality of spring pieces 23 abut against the pin.

[0034] Furthermore, the spring piece 23 has an arc surface 231 that protrudes towards the center of the socket 21. When the pin is inserted, the arc surface 231 abuts against the outer surface of the pin. The connecting terminal also includes a support ring 4, which is sleeved on the outer surface of the multiple spring pieces 23. Specifically, the position of the support ring 4 corresponds to the position of the arc surface 231. When the pin is inserted, the pin exerts an outward force on the spring piece 23 through the arc surface 231. At this time, the support ring 4 can generate an inward reaction force on the spring piece 23, making the positive force between the arc surface 231 and the outer surface of the pin greater, so as to reduce the temperature rise and improve the current conduction effect. It should also be noted that although the support ring 4 can generate a reaction force on the spring piece 23, the support ring 4 will also expand outward during the outward expansion of the spring piece 23. In this embodiment, the support ring 4 is formed by winding a strip structure along the outer surface of the multiple spring pieces 23.

[0035] Furthermore, the outer surface of the coil spring 2 also has a stepped surface 24, which abuts against the end face of the connecting seat 1 to enhance the stability of the connection between the connecting seat 1 and the coil spring 2.

[0036] In this embodiment, the coil spring 2 is made of a material with high conductivity and high yield strength to meet its conductivity and deformation requirements.

[0037] The connecting terminal also includes a first spring 5, which is disposed within the receiving groove 11 and abuts against the outer surface of the coil spring 2. In this embodiment, the first spring 5 is provided along the side wall of the receiving groove 11, and the coil spring 2 is simultaneously inserted into the receiving groove 11 and the first spring 5. It can be understood that the first spring 5 can be regarded as a connection method that fits onto the outer surface of the coil spring 2. The arrangement of the first spring 5 can improve the current conduction performance between the connecting seat 1 and the coil spring 2. In specific applications, the first spring 5 is an existing product.

[0038] The connecting terminal also includes a second spring 6, which abuts against the bottom wall of the receiving groove 11 and also abuts against the end face of the coil spring 2. The arrangement of the second spring 6 can further improve the current conduction performance between the connecting seat 1 and the coil spring 2. In specific applications, the second spring 6 is an existing product.

[0039] In summary, during use, the pin is inserted into the socket 21, and multiple springs 23 abut against the pin. At the same time, the coil spring 2 is directly connected to the connector 1. Current can be directly conducted between the pin, the coil spring 2, and the connector 1. This reduces intermediate conductive components, thereby reducing the impedance during current conduction and greatly improving current conduction performance.
