Description

Technical Field

[0001] This utility model relates to the field of assembly technology for car body insertion machines, specifically to a synchronous assembly mechanism for inserting and snapping automotive wiring harness terminals. Background Technology

[0002] To prevent the terminals from falling off due to vibration during vehicle operation and causing poor conductivity after the automotive wiring harness terminal connector is inserted into the housing, an inner housing clip is added inside the housing to lock the terminals in place and prevent them from coming loose. An integrated assembly mechanism is required during the processing of the terminal housing and the clip.

[0003] However, the existing integrated assembly mechanism still has the following technical problems in use:

[0004] Because the tolerance between the inner shell clip and the inner hole of the outer shell is sometimes small, when the inner shell is inserted into the outer shell, terminals have already been inserted in the previous process. This can easily cause secondary damage to the terminals during automatic insertion. Therefore, in many cases, the terminals are first inserted into the plastic shell, and then the inner shell clip is manually installed into the outer shell. A tooling fixture is then used to push the inner shell clip into place and lock the terminals. To address the characteristics of this product, the previous method of inserting the terminals first and then installing the inner shell clip needs to be changed. Instead, the inner shell clip should be pre-installed into the outer shell. Taking advantage of the tight fit between the inner and outer shells, the inner shell clip is pre-installed at the front end of the outer shell. After the terminals are inserted, the inner shell clip is then pushed into place.

[0005] To address the aforementioned problems, a synchronous assembly mechanism for inserting and snapping automotive wiring harness terminals is proposed. Utility Model Content
