Description

Technical Field

[0001] This utility model relates to cable plugs, and more particularly to dustproof insulating plugs for cable plugs. Background Technology

[0002] A cable plug, also known as a cable head, is in the state of not being connected, as follows: Figure 5 As shown, the insulating silicone sleeve 22 and conductive part 23 of the electrical connection of the cable plug 2 are exposed to the outdoors. In this state, there is always the possibility of dust, dust particles, water and other foreign objects entering and contaminating the insulating and conductive parts. At the same time, there is always the possibility of sharp foreign objects entering and damaging the insulating silicone and conductive parts, causing the cable plug insulation to be damaged, poor contact of the conductive rod and affecting the electrical performance of the cable plug. Therefore, it is necessary to have something to cover it so that it can play a role in preventing dust and external damage.

[0003] In the process of realizing this utility model, the inventors discovered the following problems in the prior art:

[0004] Current cable plug dust covers are cup-shaped silicone sleeves that cover the cable plugs. However, they are prone to falling off and being damaged during field operations, and their effectiveness in protecting the cable plugs is not obvious. Furthermore, if the cable plug is not connected to the socket and power is accidentally turned on, it can cause the conductive parts of the cable to discharge, resulting in discharge to the ground or even electric shock to people.

[0005] Therefore, cable plugs need to be a type of insulating and dustproof plug that can prevent dust, particles, water and other foreign objects from entering and contaminating the insulating and conductive parts, while also preventing sharp foreign objects from entering and damaging the insulating silicone and conductive parts, and is not easy to fall off, and meets the electrical insulation performance requirements. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a dustproof and insulating plug for cable plugs, which can protect the cable plugs and play an insulating role.

[0008] The operating part is located at one end of the insertion part away from the cable plug along the axial direction, the positioning part surrounds the insertion part, and a clearance space is formed between the positioning part and the insertion part for the cable plug sidewall to enter and exit.

[0009] The inner wall of the positioning part protrudes radially inward to form a positioning strip, which engages with the groove on the side wall of the cable plug to fix the dustproof insulating plug in the insertion position.

[0010] In a preferred embodiment: the insertion portion is divided into a first portion and a second portion, the second portion is arranged radially outside the first portion to form a limiting step; when the dustproof insulating plug is in the insertion position, the limiting step abuts against the silica gel sleeve of the cable plug to form a limiting fit.

[0011] In a preferred embodiment: the operation portion extends radially outward from one side of the insertion portion to form a ring-shaped protrusion.

[0012] In a preferred embodiment: the insertion portion protrudes outward from the positioning portion.

[0013] In a preferred embodiment: the end of the insertion portion is provided with an opening, which is in communication with the channel inside the insertion portion.

[0021] In order to make the technical scheme and characteristics of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and specific examples, and it should be understood that these examples are only used to illustrate the utility model and not used to limit the scope of the utility model, and after reading the utility model, various equivalent modifications of the utility model made by those skilled in the art all fall within the scope defined by the claims attached to the present application.

[0022] REFERENCE Figures 1-5The dustproof and insulating plug for the cable plug comprises an insertion part 1 for being inserted into the cable plug 2, a positioning part 3 for being releasably combined with the side of the cable plug 2 and an operating part 4 for being held;

[0023] The operating part 4 is arranged at one end of the insertion part 1 away from the cable plug 2 along the axial direction, the positioning part 3 is arranged around the insertion part 1, and a space is formed between the positioning part 3 and the insertion part 1 for the side wall of the cable plug 2 to pass through;

[0024] The inner wall of the positioning part 3 is protruded inward along the radial direction to form a positioning clamping strip 31, so as to be combined with the groove 21 of the side wall of the cable plug 2 to fix the dustproof and insulating plug in the insertion position.

[0025] In order to limit the insertion depth of the dustproof and insulating plug, the insertion part 1 is divided into a first part 11 and a second part 12, the second part 12 is arranged outside the first part 11 along the radial direction to form a limiting step, and the limiting step is abutted with the silica gel sleeve 22 of the cable plug 2 to form a limiting combination when the dustproof and insulating plug is in the insertion position.

[0026] In order to facilitate the user to hold the operating part 4, the side of the operating part 4 away from the insertion part 1 is extended outward along the radial direction to form a ring of convex edges 41.

[0027] Finally, the insertion part 1 is protruded outward relative to the positioning part 3. The end of the insertion part 1 is provided with an opening, and the channel 13 inside the insertion part 1 is communicated.
