DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0016] like Figure 1 to Figure 4 As shown, an insulating cover plate for wiring of an electrical cabinet is installed on the back plate of the electrical cabinet, the insulating cover plate includes a front cover plate 1 and a rear cover plate 2, a plurality of wire threading sleeves 3 are connected between the front cover plate 1 and the rear cover plate 2, the wire threading sleeves 3 are evenly distributed between the front cover plate 1 and the rear cover plate 2, and wire threading holes 4 are arranged in the wire threading sleeves 3. During installation, the cables pass through the wire threading holes 4. Since the wire threading sleeves 3 are evenly distributed between the front cover plate 1 and the rear cover plate 2, the cables are separated to avoid entanglement between the cables.

[0017] The outer periphery of the threading sleeve 3 is provided with reinforcing ribs 5, which are integrally formed with the front cover plate 1, the rear cover plate 2 and the threading sleeve 3. The two ends of the reinforcing ribs 5 are respectively connected to the front cover plate 1 and the rear cover plate 2. By providing the reinforcing ribs 5, the bearing capacity of the threading sleeve 3 is improved.

[0018] Step holes 6 are provided on both sides of the threading hole 4, and sealing rings 7 are installed at the step holes 6. When installed, the sealing ring 7 is sleeved on the cable. In this embodiment, the sealing ring 7 includes a positioning portion 711, and a sealing portion 712 is provided on the positioning portion 711. A shrinkage hole 713 is provided in the middle of the sealing portion 712. The cable passes through the shrinkage hole 713, and a release groove 714 is opened around the sealing portion 712. By providing the release groove, the resistance of the cable when passing through the shrinkage hole is reduced.

[0019] The rear cover plate 2 is provided with a connection seat 8 around which screw holes are processed. The back plate of the electrical cabinet is evenly provided with studs 9, and the front cover plate 1 is provided with connection holes 10. Figure 5As shown, when the insulating cover is installed, the back plate 2 of the electrical cabinet is connected to the screw hole of the connecting seat 8 by screw 1, and the connecting hole 10 of the front cover 1 is connected to the stud 9 by screw 2. The front and rear covers are both connected to the back plate of the electrical cabinet to improve the installation strength of the insulating cover.

[0020] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
