Abstract

The invention discloses a check device for communication cables, and the check device comprises an annular check ring, wherein the lateral wall of the check ring is provide with an check arc piece array formed by check arc pieces; in addition, the check arc pieces bend to the center of the check ring. By utilizing the check arc piece array on the lateral wall of the check ring in the check device for the communication cables, the communication cables will be extruded by the check arc pieces after passing through the check device, and the retraction and shifting of the communication cables can be effectively prevented. Therefore, the fixing reliability of the communication cables is greatly improved, and the laying efficiency of the communication cables is also enhanced.

Description

Non-return device of communication cable

Technical Field

The invention relates to communication equipment, in particular to a backstop of a communication cable.

Background

Communication cables, a very common communication connection device, are typically located underground. When the cables are laid, the cables need to be pulled manually, so that the cables are laid in the preset culvert. In the process of drawing the cable, the cable is easy to retract and shift due to the tension of the skin of the cable, and the laying efficiency of the communication cable is affected.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a backstop for a communication cable.

The technical problem of the invention is mainly solved by the following technical scheme:

the utility model provides a non return ware of communication cable, communication cable's non return ware contain an annular non return circle, the lateral wall of non return circle on be equipped with the non return arc piece array of constituteing by non return arc piece, non return arc piece to the center of non return circle crooked.

As a preferred embodiment of the invention, the check ring and the check arc sheet are integrally formed by stainless steel sheets.

As a preferred embodiment of the invention, the check ring and the check arc sheet are integrally formed by rubber.

The backstop device of the communication cable utilizes the backstop arc sheet array on the outer side wall of the backstop ring, and the communication cable can be extruded by the backstop arc sheets after passing through the backstop arc sheet array, so that the communication cable is effectively prevented from retracting and shifting, the fixing reliability of the communication cable is greatly improved, and the laying efficiency of the communication cable is also improved.

Drawings

FIG. 1 is a perspective view of a backstop for a communication cable of the present invention;

FIG. 2 is a perspective view of the backstop of the communication cable of FIG. 1, shown from another perspective;

FIG. 3 is an enlarged detail view of area A of the backstop of the communication cable of FIG. 2;

wherein,

1. a backstop for a communication cable; 2. a non-return ring; 3. non-return arc sheet.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.

As shown in fig. 1 to 3, the backstop 1 of the communication cable of the present invention comprises an annular backstop ring 2, wherein an arc backstop sheet array consisting of arc backstop sheets 3 is arranged on the outer side wall of the backstop ring 2, and the arc backstop sheets 3 are bent toward the center of the backstop ring 2.

The non-return ring 2 and the non-return arc sheet 3 are integrally formed by stainless steel sheets.

The non-return ring 2 and the non-return arc sheet 3 are integrally formed by rubber.

Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
