DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figures 1 to 3 As shown, the utility model provides a multi-core cable electric control box, including an upper cable inlet hole plate 21, a lower cable inlet hole plate 22, and fasteners. In this embodiment, the fasteners are fastening butterfly screws 7;

[0028] The electric control box 1 is provided with a wiring slot 11, which is a rectangular slot design provided on one end surface of the electric control box. Compared with the prior art design of several small slots for entering the wire, the design of a whole large rectangular slot is very easy to process the electric control box 1. When entering the wire, the cable 4 can be more easily entered into the electric control box 1, without the need to align the small slots one by one, and there is also a larger operating space when wiring.

[0029] The upper cable entry hole plate 21 and the lower cable entry hole plate 22 are arranged on the outside of the wiring through groove 11, and the fastening butterfly screw 7 penetrates the displacement slide groove 24 on the upper cable entry hole plate 21 and the lower cable entry hole plate 22 and is threadedly connected with the nut in the electric control box 1. When the fastening butterfly screw 7 is not tightened, the upper cable entry hole plate 21 and the lower cable entry hole plate 22 can slide back or toward each other through the threaded cylinder of the fastening butterfly screw 7, thereby realizing the opening (the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are both away from the wiring through groove 11) or closing (the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are covered on the wiring through groove 11 after being matched);

[0030] When the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are joined together, they can enclose to form a cable through hole 23. By tightening the fastening butterfly screws 7, the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are kept in a fastened state, thereby achieving the limitation of the cable 4 that has been connected.

[0031] Specifically, the electrical plug used to connect the cable adopts a spring-pressed plug-in plug 31. After the spring-pressed plug-in plug 31 is plugged into the cable 4, it is fixed by the spring clip inside it. This plug is an existing commercially available product, which can be seen at (https: / / detail.1688.com / offer / 666228388898.html); its price is much lower than that of an industrial aviation plug, and the socket corresponding to the spring-pressed plug-in plug 31 is fixed in the electric control box 1.

[0032] Furthermore, since the cable control box needs to be functionally debugged in the factory before leaving the factory, this means that these cables 4 need to be connected and tested in the factory first; by using the spring-pressed plug-in plug 31, the spring-pressed plug-in plug 31 and the cable guard 41 can be directly packaged together after the test is completed as a prefabricated cable connector. After arriving at the site, they can be directly connected according to the number of the cable 4 or the spring-pressed plug-in plug 31, which is extremely quick.

[0033] Specifically, semicircular holes are provided on the bottom end of the upper cable entry hole plate 21 and the top end of the lower cable entry hole plate 22. When the bottom end of the upper cable entry hole plate 21 is matched with the lower cable entry hole plate 22, the two semicircular holes in each group enclose a cable through-hole 23. The semicircular holes can be formed on the upper cable entry hole plate 21 and the lower cable entry hole plate 22 by stamping.

[0034] Specifically, the cable 4 is connected with a cable guard 41, and the two sets of adjusting nuts 411 of the cable guard 41 are respectively located on the inner side and the outer side of the cable through hole 23. Since the width of the two sets of adjusting nuts 411 is greater than the width of the cable through hole 23, the two sets of adjusting nuts 411 are connected with the cable through hole 23.

[0035] The cable guard 41 is a commercially available standard part, which is configured according to the thickness of the cable 4. After the cable 4 is inserted into the entrance guard, the locking sleeve and the waterproof rubber sleeve inside the guard are tightened, which provides a guarantee for the fastening and waterproofing of the cable 4 and the cable guard 41. Even if there is a large error in the thickness of the cable 4, the cable guard 41 has a large shrinkage range, so that the cable through hole 23 and the cable guard 41 are clamped, further improving the sealing.

[0036] Specifically, the displacement slide groove 24 is of a long strip structure, which extends along the height direction of the electric control box 1, so that the upper cable inlet hole plate 21 and the lower cable inlet hole plate 22 can slide up and down along the height direction of the electric control box 1.

[0037] like Figure 4As shown, specifically, the upper cable entry hole plate 21 and the lower cable entry hole plate 22 on the inner side of the two groups of displacement slide grooves 24 are also provided with semi-annular sealing strips 5. When the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are matched together, the two groups of semi-annular sealing strips 5 are also matched together to form annular strips to fill the gap between the electric control box 1, the upper cable entry hole plate 21, and the lower cable entry hole plate 22, thereby improving the sealing performance.

[0038] Specifically, the sides of the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are constructed with inwardly bent vertical ribs 6, which on the one hand reduce the gap between the electric control box 1, the upper cable entry hole plate 21, and the lower cable entry hole plate 22, and on the other hand provide better structural strength support for the installation of the cable guard 41.

[0039] The working principle and working process of the utility model are as follows:

[0040] When wiring the cables, first slide the upper cable entry hole plate 21 and the lower cable entry hole plate 22 away from each other along the threaded column of the fastening butterfly screw 7, so that the upper cable entry hole plate 21 and the lower cable entry hole plate 22 are both away from the wiring groove 11, and then connect the cable guard 41 with the cable 4, and after the cable 4 passes through the wiring groove 11, connect it with the spring-pressed plug-in plug 31, and then slide the upper cable entry hole plate 21 and the lower cable entry hole plate 22 toward each other along the threaded column of the fastening butterfly screw 7 until the cable guard 41 is engaged with the cable through-hole 23 formed by the upper cable entry hole plate 21 and the lower cable entry hole plate 22 being joined together, and finally tighten the fastening butterfly screw 7 to keep the upper cable entry hole plate 21 and the lower cable entry hole plate 22 in a fastened joined state.

[0041] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
