The housing 100 is generally used to house terminals as a protective enclosure for the terminals and cables. The cable needs to pass through the wire inlet 111, extend into the interior of the box 100, and then connect the cable end with the terminal. The first crimp 300 is capable of holding a larger size of an object than the second crimp 500 is capable of holding, corresponding to the bellows and the cable, respectively. I.e. the first crimp 300 is used for securing the bellows and the second crimp 500 is used for securing the cable.

If the corrugated pipe is not sleeved outside the cable, after the cable connector is connected, the first cover plate 200 is covered at the first opening groove 110, and the first cover plate 200 can be clamped and fixed with the box body 100. Then, the second cover plate 400 is covered at the second opening groove 210, the second cover plate 400 can be clamped and fixed with the first cover plate 200, and meanwhile, the second press connection part 500 can press and fix the cable on the box body 100.

If the cable is not sleeved with a bellows, only the cable is connected, and when the second cover plate 400 is covered on the second opening groove 210, the first toothed plate 510 and the second toothed plate 520 can press the cable skin. Specifically, the second cover plate 400 covers the second open slot 210, and the first toothed plate 510 and the second toothed plate 520 are close to each other until the first toothed plate 510 and the second toothed plate 520 crimp the cable, and of course, the teeth on the first toothed plate 510 and the second toothed plate 520 can better grip the cable.

It is understood that the opposite surfaces of the first toothed plate 510 and the second toothed plate 520 are arc-shaped, and the teeth on the first toothed plate 510 are distributed along the arc shape, and the teeth on the second toothed plate 520 are also distributed along the arc shape.

A plurality of first clamping portions 610 are provided, so that the position of the first cover plate 200 clamped inwards can be flexibly adjusted according to corrugated pipes with different sizes. For example, the bellows has smaller size, and the first cover plate 200 is further biased to the inner side of the box body 100 after being covered by the first open slot 110; the bellows is larger in size and the first cover 200 is more biased to the outside of the case 100.

It will be appreciated that the second cover plate 400 and the second opening slot 210 may be of the same or similar design, and the second cover plate 400 may be clamped in the second opening slot 210, i.e. the second cover plate 400 is clamped with the first cover plate 200.
