Description

Technical Field

[0001] This utility model relates to the field of motherboard connectors, and more particularly to a wire-end connector device. Background Technology

[0002] Computer motherboards require board-side connectors and wire-side connectors for external connections. In existing wire-side connectors, the connection between the wire and the terminal is usually achieved by punching, which deforms the terminal through stamping and then presses the wire together. After soldering the wire, this type of terminal often pulls the wire during insertion and removal, resulting in the pin coming out. This indicates that the connection between the terminal and the insulator is unstable, causing the terminal to be pulled out. Most existing connectors are single-sided contacts, which are prone to poor contact problems. Utility Model Content

[0004] An insulating body includes a mating portion on one side and a soldering portion on the opposite side of the mating portion, the mating portion pointing towards the opposite connector; the mating portion has spacers arranged on it, and anti-retraction portions are provided between the spacers.

[0005] The mating part is provided with a conductor, which bends from the upper part of the dividing section to the lower part of the anti-retraction part, and passes through the insulating body to the welding part. The conductor is assembled on the mating part in the opposite direction of the mating direction.

Figure 4 , Figure 5 As shown, the conductor 6 bends from the upper part of the separating section 4 to the lower part of the anti-retraction part 5, and passes through the insulating body 1 to the welding part 3. The conductor 6 is assembled onto the insertion part 2 in the opposite direction of the insertion direction of the insertion part 2. In this embodiment, as shown... Figure 3 As shown, conductor 6 is a U-shaped mechanism, but it is not limited to a U-shape. Conductor 6 is bent and assembled onto the mating part 2 from the opposite direction of the mating direction. A baffle 7 is provided between the upper part of the separating section 4 and the insulating body 1, as shown... Figure 6 As shown, a positioning cavity 8 is formed between the baffle 7, the anti-retraction part 5, and the insulating body 1. One end of the conductor 6 extends into the positioning cavity 8. The bent position of the conductor 6 is fitted onto the anti-retraction part 5, and the other end extends below the anti-retraction part 5 and passes through the insulating body 1 to its welding part 3. The welding part 3 is provided with a through groove 12 for placing one end of the conductor 6. The through groove 12 extends below the anti-retraction part 5 to facilitate the passage of the conductor 6.
