Description

Technical Field

[0001] This utility model relates to the field of assembly technology for car wiring harness insertion machines, specifically to a pre-assembly mechanism for the inner shell buckle of an automotive wiring harness insertion machine. Background Technology

[0002] After the automotive wiring harness terminal connector is inserted into the housing, in order to prevent the terminal from falling off due to vibration during vehicle operation and causing poor conductivity, an inner housing snap-fit ​​accessory is added inside the housing to lock the terminal in place and prevent it from coming loose. This process requires the use of an inner housing snap-fit ​​assembly mechanism.

[0003] However, the existing inner shell snap-fit ​​pre-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] Therefore, a pre-installation mechanism for the inner shell of an automotive wiring harness inserter is proposed to solve the aforementioned problems. Utility Model Content

The left end of the first support frame 1 is fixedly installed with... A shell flipping mechanism bracket 15 is provided. A shell flipping 90-degree cylinder 16 is installed on the left side wall of the shell flipping mechanism bracket 15. Symmetrical shell flipping mechanism side baffles 17 are rotatably installed on the right side wall of the shell flipping mechanism bracket 15. A shell flipping material frame 18 is fixedly installed between the two shell flipping mechanism side baffles 17. The right end of the shell flipping 90-degree cylinder 16 is fixedly connected to the side wall of the shell flipping mechanism side baffle 17. The inner shell snap-fit ​​horizontal rotation mechanism is composed of an inner shell snap-fit ​​horizontal rotation mechanism base plate 3, an inner shell snap-fit ​​horizontal rotation tray 10, an inner shell snap-fit ​​horizontal rotation cylinder 9, an inner shell snap-fit ​​pressing cylinder 12, and an inner shell snap-fit ​​pushing rod 13. The shell flipping mechanism bracket 15 and the shell flipping 90-degree cylinder 16 are also included.
