Abstract

The utility model discloses a protection sleeve for a cable through pipe, and the section shape is a hollow spindle structure, a convex ring vertical to the central line is arranged in the middle of an external wall of the spindle, a symmetrical external ring surface which is parallel to the internal wall of the spindle is arranged on the upper ring surface and the lower ring surface of the convex ring, an external diameter of the external wall surface extends from the external ring surface to the two pipe ports is contracting; a contracting side can be arranged on the two pipe ports. The protection sleeve for the cable through pipe insulates the cable and the pipe body to avoid the damage of the external cable surface by a tough contact of the cable external surface and the pipe port, the internal wall of the protection sleeve for the cable through pipe matches closely with the external cable surface to prevent rain from entering into the pipe body along the external cable surface, meanwhile, the convex ring of the protection sleeve for the cable through pipe is fastened on the pipe port to prevent rain from entering into the pipe body along the internal wall of the pipe body, extends the service life of the cable and the pipe body through the ground, and has the advantages of simple structure and easy installation and use.

Description

The cable pipe protective jacket

Technical field

The utility model relates to the protective jacket that a kind of cable pipe end socket is used.

Background technology

In electric power, telecommunications installing engineering, the upper end that high and low pressure is worn ground cable and telecommunication cable exposes the outside at body, rainwater para-electric cable exocuticle flow in the body during rainy day, cause the corrosion of the aging and inboard wall of tube body of cable exocuticle, while cable and body port part Long contact time, owing to reasons such as wind-force, easily cause the breakage of cable exocuticle, influence the insulating properties and the shielding of cable.

Summary of the invention

The purpose of this utility model provides a kind of anti-rainwater, does not damage the cable pipe protective jacket of cable exocuticle.

For achieving the above object, cross sectional shape of the present utility model is hollow spindle structure, the middle part of spindle outer wall is provided with the bulge loop perpendicular to its center line, respectively there is outer ring surface one section symmetry, parallel with the spindle inwall both sides of anchor ring up and down of bulge loop, are the convergent state from outer ring surface to the external diameter of the outside wall surface of two remote extension to two spout parts.

That stretches in can also being provided with on described two mouth of pipe positions tightens up the limit.

After adopting said structure, the cable pipe protective jacket is isolated cable and body, avoid the cable exocuticle to contact and cause the damage of cable exocuticle with the rigidity of body spout part, the inwall of cable pipe protective jacket and cable exocuticle closely cooperate, rainwater can not be flow in the body along the cable exocuticle, the bulge loop spiral-lock of cable pipe protective jacket is in the port part of body simultaneously, rainwater can not be flow in the body along inboard wall of tube body, the useful life that prolongs cable and wear the ground body, and it is simple in structure, installation, easy to use.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Description of drawings

Fig. 1 is a surface structure schematic diagram of the present utility model;

Fig. 2 is the A-A generalized section of first embodiment of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

The A-A generalized section of second embodiment of Fig. 4 Fig. 1.

Embodiment

Fig. 1-cable pipe protective jacket shown in Figure 3, its cross sectional shape is hollow spindle structure, hollow internal diameter and outside diameter of cable coupling, the middle part of spindle outer wall is provided with the bulge loop 1 perpendicular to its center line, respectively there is outer ring surface 2 one section symmetry, parallel with spindle inwall 3 both sides of anchor ring up and down of bulge loop 1, be the convergent state from outer ring surface 2 to the external diameter of the outside wall surface 4 of two remote extension to two spout parts, spindle inwall 3 is 10 °-20 ° with the angle a of outside wall surface 4.

Cable pipe protective jacket shown in Figure 4, its planform and aforementioned structure are basic identical, and that stretches in just being provided with on described two mouth of pipe positions tightens up limit 5, and this tightens up limit 5 and has elasticity.

The material that above-mentioned cable pipe protective jacket adopts can be rubber, nylon, plastics elastomeric material, the structure at the two ends of cable pipe protective jacket can be asymmetric, adopting symmetrical structure is in order to install, in the use, need not to distinguish upper and lower end, easy to use.According to the high and low pressure power cable, the difference of the external diameter of telecommunication cable and cable TV optical cable can be produced the cable pipe protective jacket of plurality of specifications model.Can also be provided with and body mouth of pipe corresponding groove on the anchor ring on the described bulge loop 1 or down, water sealing property is better, when the cable of having installed is used this cable pipe protective jacket, can be along severing on the outside wall surface that is parallel to its center line, spiral-lock is cut the portion of meeting and is got final product with bonding agent is bonding on cable.

Claims

1, a kind of cable pipe protective jacket, it is characterized in that its cross sectional shape is hollow spindle structure, the middle part of spindle outer wall is provided with the bulge loop (1) perpendicular to its center line, respectively there is outer ring surface one section symmetry, parallel with spindle inwall (3) (2) both sides of anchor ring up and down of bulge loop (1), are the convergent state from outer ring surface (2) to the external diameter of the outside wall surface (4) of two remote extension to two spout parts.

2, cable pipe protective jacket according to claim 1, what it is characterized in that described two mouth of pipe positions stretch in being provided with tightens up limit (5).
