AI Technical Summary
The existing junction box connectors are of uniform size, which cannot meet the needs of different usage scenarios, resulting in unstable wiring harness connections, signal interference and short circuit risks, and inconvenience in installation and maintenance.
The junction box is designed with differentiated wiring hole diameters, combined with threaded structure and snap-fit blocks, and uses a compression-shrinking fixing method. With the help of washers and arc-shaped support edges, it can achieve a stable connection and sealed protection for multi-specification wire harnesses.
It achieves precise adaptation of wire harnesses of different specifications, reduces the risk of signal interference and short circuits, improves equipment reliability, simplifies installation and maintenance, and extends equipment lifespan.

Abstract
Claims
1. A terminal box comprising a box body, a cover plate being provided on the box body, characterized in that: The outer peripheral wall of the box is provided with a number of wiring holes of different diameters. Each wiring hole is fitted with a connector. The connector is hollow and has a through hole. The connector is provided with a first thread and a second thread. The first thread is threaded to fit a fastening nut. The end of the connector near the second thread is provided with a number of locking blocks. The second thread is threaded to fit a tightening cap. The inner wall of the tightening cap is provided with a retaining slope for abutting the locking blocks to close them. The connector is also provided with a retaining platform between the first thread and the second thread for shielding the wiring holes.
2. The junction box of claim 1, wherein: The box body is provided with a positioning buckle along its edge, and the positioning buckle is provided with an adjustment elongated hole.
3. The junction box of claim 2, wherein: The box body has supporting edges at its four corners, and the supporting edges are arc-shaped.
4. The junction box of claim 3, wherein: Washers are provided between the fastening nut and the housing, and between the contact platform and the housing.
5. The junction box according to claim 2, characterized in that: A fastening platform is provided on the cover plate along the circumference, and a locking screw is fitted on the fastening platform. A fastening hole is provided on the box body corresponding to the position of the fastening platform, and the locking screw is tightly fitted with the fastening hole.
