Abstract
Description
Technical Field

[0019] Figure 4 yes Figure 1 Side view. Detailed Implementation
[0020] Please see Figures 1 to 4 As shown, the electrical connection terminal assembly 1000 of this utility model includes an electrical connection terminal 100 and a cable 200 assembled on the electrical connection terminal 100. The electrical connection terminal 100 is formed by stamping a metal plate and is plate-shaped. The electrical connection terminal 100 includes a crimping part 1 and a contact part 2 extending forward from the crimping part 1. The cable 200 includes a core wire 3 and a covering body 4 covering the core wire 3.
[0021] The crimping portion 1 includes a substrate 11 and a crimping portion 12 extending from one side of the substrate 11 in the width direction. The crimping portion 12 is used for electrical connection with the core wire 3 of the cable 200. The crimping portion 12 is wound and pressed against the outer periphery of the core wire 3 to achieve electrical connection with the core wire 3. In this invention, the contact portion 2 and the surface of the substrate 11 are located in the same plane. A plurality of crimping portions 12 are integrally formed on the same side of the substrate 11 in the width direction. The plurality of crimping portions 12 are staggered in the front-back direction. Adjacent crimping portions 12 form an accommodating space 120 for accommodating the core wire 3 of the cable 200 in the thickness direction of the substrate 11. The contact portion 2 includes a pair of opposing snap-fit arms 21, each snap-fit arm 21 having a contact point 210.
[0022] Specifically, the plurality of pressure wire portions 12 include two first pressure wire portions 12a and a first pressure wire portion 12b located between the two first pressure wire portions 12a in the front-back direction. The two first pressure wire portions 12a are pre-bent relative to the substrate 11 and located on a first side in the thickness direction of the substrate 11, and the second pressure wire portion 12b is pre-bent relative to the substrate 11 and located on a second side in the thickness direction of the substrate 11. At this time, the two first pressure wire portions 12a and the second pressure wire portion 12b form an upwardly open receiving space 120 in the thickness direction of the substrate 11. The width of the receiving space 120 is not greater than the diameter of the core wire 3, so that the core wire 3 can be pre-fixed after being inserted into the receiving space 120. After the core wire 3 of the cable 200 is inserted into the receiving space 120, the first pressing part 12a and the second pressing part 12b are respectively located on both sides of the core wire 3 to pre-fix the core wire 3. The first pressing part 12a and the second pressing part 12b are rolled and pressed so that the first pressing part 12a and the second pressing part 12b form a semi-circular structure that presses the core wire 3 of the cable 200. It is worth noting that in this utility model, the pair of first pressing parts 12a and second pressing parts 12b located on both sides of the core wire 3 are rolled and pressed towards the opposite side of the core wire 3, so that the pressing parts 12 tightly press the core wire 3 and make reliable contact between the two, thereby allowing the electrical connection terminal to achieve a reliable electrical connection between the two without having to be directly connected to the core wire 3 of the cable 200.
[0023] In this invention, the substrate 11 extends rearward from the lower rear end of the contact portion 2, and the pressure wire portion 12 is located at the rear end of the contact portion 2 and within the width range of the contact portion 2. It should be noted that the pressure wire portion 12 is only within the width range of the contact portion 2 after being rolled and pressed. By effectively utilizing the space above the substrate 11 behind the contact portion 2, the overall size of the electrical connection terminal assembly 1000 can be reduced.
[0024] In a specific embodiment of this utility model, the electrical connection terminal assembly 1000 includes a cable 200 and two electrical connection terminals 100 electrically connected to the cable 200. The sheath 4 of the cable 200 covers two core wires 3, which are signal core wires, and each signal core wire is electrically connected to one electrical connection terminal 100. The two first pressure-fit portions 12a of the two electrical connection terminals 100 are arranged opposite each other in the thickness direction of the substrate 11, and the second pressure-fit portions 12b of the two electrical connection terminals 100 are also arranged opposite each other in the thickness direction of the substrate 11.
