Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 , a waterproof sealing structure for electric wire through holes, comprising a through-hole inner flange 2 , a sealing member 3 and a pressing frame 4 arranged on an electric wire through hole 11 of an electric appliance 1 .

[0029] The seal 3 is made of elastic material. The seal 3 includes an elastic sealing sleeve 31 and a base ring 32 . The base ring 32 and the elastic sealing sleeve 31 are integrally structured. The elastic sealing sleeve 31 is a reversible structure. The elastic sealing sleeve 32 extends toward the outside of the electrical appliance 1 . The inner surface 311 of the elastic sealing sleeve is a conical surface. The outer surface 312 of the elastic sealing sleeve is a conical surface. The outer radius of the lower end of the elastic sealing sleeve 31 is large, and the outer radius of the upper end is small...

Abstract

The invention relates to the technical field of electrical equipment waterproof and sealing. An electrical equipment wire via hole waterproof sealing structure comprises a sealing element. The sealing element comprises an elastic sealing sleeve and a base ring, wherein the elastic sealing sleeve is used for being arranged on a wire in sealing and sleeved mode, and the base ring is arranged at one end of the elastic sealing sleeve in sealing and butt joint modes. The base ring is connected on the electrical equipment wire via hole in a sealed mode. The inner surface of the elastic sealing sleeve is a conical surface. The area of an opening of one end of the elastic sealing sleeve is large, wherein the end of the elastic sealing sleeve is connected with the base ring. The area of an opening of the other end of the elastic sealing sleeve is small, wherein the other end of the elastic sleeve is far away from the base ring. The wire via hole waterproof sealing structure capable of being suitable for external diameters of different wires and a waterproof sealing method are provided, the problem of poor using convenience caused by an existing detachable electrical equipment wire via hole waterproof sealing method is solved.

Description

technical field [0001] The invention relates to the technical field of waterproof sealing of electrical appliances, in particular to a waterproof sealing structure and a waterproof sealing method for electric wire through holes. Background technique [0002] When electrical appliances (such as plugs, sockets, etc.) are used in places that require waterproofing, waterproof measures must be taken at the electrical wire hole (that is, the hole where the power supply line penetrates into the electrical appliance). [0003] There are two existing methods of waterproofing electrical wire through holes: one is to seal and connect the wires to the electrical wire through holes by casting and wrapping at the electrical wire through holes, and when the existing plugs need to be waterproofed Use this method more often. For example, the waterproof plug disclosed in the patent document with the Chinese patent number 2011201601553, the date of authorization announcement is November 1...
