Description

Shrinkage three-core intermediate head main body

Technical Field

The utility model relates to an intermediate head, especially a three core intermediate head main parts of shrinkage.

Background

With the popularization of power cabling engineering, the accident rate of cables is increased, and a great deal of facts prove that most cable accidents are related to cable accessories, particularly cable intermediate joints. In the existing cable intermediate joint, in order to prevent moisture from entering the intermediate joint, a method of winding a waterproof tape around the end part of the joint body is generally adopted.

However, in the installation process of the cable intermediate joint main body, the copper mesh company uses the cable tie for fixing, but in the fastening process of the cable tie, the time consumption is long; the copper mesh is generally fixed by using a (constant force) spring in the market, but the spring has the problem of loose elasticity after being used for a certain time, so that the copper mesh is loosened, and the structure in the middle joint main body is damaged.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a three core intermediate head main parts of shrinkage.

The technical scheme of the utility model is that: the utility model provides a three-core intermediate head main part of shrinkage, is including weaving ground wire, copper mesh, cassette, copper shield, armor, inner sheath, oversheath, waterproof sticky tape, the both ends of weaving the ground wire are provided with the copper shield, the both ends of copper shield are equipped with inner sheath, armor and oversheath in proper order, the copper mesh cover is located outside weaving the ground wire, the copper mesh passes through the cassette and fixes on both ends copper shield, a plurality of card hole has been seted up on the area body of cassette, the end of cassette is equipped with the pothook, each the cassette is wrapped up in the both ends of copper mesh, its pothook is firmly hooked and is established in the card hole that is fit for, waterproof sticky tape wraps up the one deck in the intermediate head main part, from one end inner sheath to other end inner sheath.

Preferably, the braided ground wire is a grounding copper braided wire.

Preferably, the waterproof tape is a PVC tape.

Preferably, the waterproof tape is wrapped in a half lap joint manner around the intermediate joint body by one layer from one end inner sheath to the other end inner sheath.

Preferably, the hook is an L-shaped plate.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a pair of three core intermediate head main parts of shrinkage, copper mesh adopt the cassette tape fixed, when fixed, with the pothook hook of cassette tape one end go into its suitable card downthehole can, the hook is established consuming time less, can not appear using the lax condition of elasticity of a specified duration yet simultaneously, has guaranteed the life of intermediate head main part.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 4, the cold-shrink three-core intermediate head main body comprises a grounding copper braided wire 1, a copper mesh 2, a clamping band 3, a copper shield 4, an armor 5, an inner sheath 6, an outer sheath 7 and a PVC tape 8.

The both ends of ground connection copper braided wire 1 are provided with copper shield 2, and the both ends of copper shield 2 are equipped with inner sheath 6, armor 5 and oversheath 7 in proper order, and copper mesh 2 covers and locates outside ground connection copper braided wire 1.

Copper mesh 2 is fixed on both ends copper shield 4 through cassette 3, has seted up a plurality of card hole 31 on this cassette 3's the area body, and the end of cassette 3 is equipped with pothook 32, and pothook 32 is the L template, and each cassette 3 wraps up at the both ends of copper mesh 2, and its pothook 32 firmly hooks and establishes in suitable card hole 31, firmly fixes steel mesh 2, can not become flexible.

This PVC sticky tape 8 wraps the one deck on the intermediate head main part with half overlap joint mode, from one end inner sheath to other end inner sheath.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the right of the present invention should not be limited thereby, and therefore, modifications, equivalent changes, improvements, etc. made in the claims of the present invention are still included in the scope of the present invention.
