Problems solved by technology

[0003] The cables are connected to various power equipment for power transmission. Therefore, the power equipment is usually equipped with threading holes, and in order to prevent dust, rubber sleeves are also installed in the threading holes, but ordinary rubber sleeves are difficult to achieve The waterproofing and positioning of the cables make it easy for the power equipment to be damaged due to water entering the wiring holes. When the cables are pulled due to gravity or wind, it is easy to cause the wiring to loosen, which needs to be improved.

Embodiment Construction

[0020] Combine below figure 1 And further illustrate the technical solution of the present invention through specific examples.

[0021] Such as figure 1 As shown, the present invention provides a high-stability cable positioning and sealing method, including: a tapered hole is provided at the front end of the first threading hole 16 on the sleeve 2, the elastic body 10 is a cylinder and the tail end is provided with a tapered hole. A ring of conical surfaces corresponding to the shaped hole, so that the elastic body 10 and the sleeve 2 are closely matched, so as to facilitate the sealing of the contact part of the sleeve 2 and the elastic body 10; The second threading hole 15 is deformed by extruding the elastic body 10 so that the second threading hole 15 shrinks to strengthen the sealing of the cable; the locking assembly is symmetrically arranged on both sides of the sleeve 2 and the pressing ring 11 to pull the pressing ring 11 solid.

[0022] In this embodiment, the f...

Abstract

The invention discloses a high-stability cable positioning and sealing method which comprises the following steps: a conical hole is formed in the front end of a first threading hole in a sleeve, an elastic body is a cylinder, and a circle of conical surface corresponding to the conical hole is arranged at the tail end of the elastic body, so that the elastic body is tightly matched with the sleeve, and the contact part of the sleeve and the elastic body is conveniently sealed; a second threading hole concentric with the first threading hole is formed in the elastic body, and the elastic bodyis extruded to deform, so that the second threading hole is shrunk, and the sealing of the cable is enhanced; and the lock catch assemblies are symmetrically arranged on the two sides of the sleeve and the pressing ring to pull and fix the pressing ring. According to the high-stability cable positioning and sealing method, the lock assembles is used for pulling and fixing the pressing ring, the elastic body is extruded to deform, so that the second threading hole shrinks, the sealing of the cable is enhanced, the stability of axial positioning of the cable is improved due to the increase of static friction, the loosening problem during pulling is reduced, and the wiring position is firmer.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a high-stability cable positioning and sealing method. Background technique [0002] Cables are widely used and are usually composed of several groups of wires. Each group of wires is insulated from each other, and the entire outside is covered with a highly insulating covering layer to bind and protect the wires and improve the overall structural stability. [0003] The cables are connected to various power equipment for power transmission. Therefore, the power equipment is usually equipped with threading holes, and in order to prevent dust, rubber sleeves are also installed in the threading holes, but ordinary rubber sleeves are difficult to achieve The waterproofing and the positioning of the cables make it easy for the power equipment to be damaged due to water entering the wiring holes. When the cables are pulled by gravity or wind, it is easy to cause the wiring to loosen,...
