Abstract

A cable down lead bushing is a steel bushing arranged in order to prevent a cable down lead from being accidentally damaged or bumped. The waterproof plugging means of common cable down lead bushings applied in a current power grid needs improving. In a current technical scheme, fireproof plugging mud is mainly adopted to plug the interface of a bushing. It is common that water enters the bushing due to the expiration of plugging materials. Accumulated water is then frozen and extrudes a cable which is thus damaged. Therefore, it is necessary to provide a cable down lead bushing plugging material protecting device. The cable down lead bushing plugging material protecting device comprises a skirt type main body and double-side snap-fastening edges integrally formed with the main body. After plugging materials are filled in cable down lead bushings, the service lifetimes of the plugging materials can be significantly prolonged by arranging the protecting device. Manpower and materials are saved. The possibility of damaging cables is further lowered.

Description

Optical cable downlead sleeve pipe plugging material protective device

technical field:

The utility model relates to a kind of electric equipment protection device, particularly a kind of optical cable downlead sleeve pipe plugging material protective device.

background technology:

Optical cable downlead sleeve pipe is exactly for preventing that the optical cable downlead is subject to the steel sleeve pipe that accidental destruction or shock install additional, optical cable downlead sleeve pipe waterproof shutoff mode commonly used in current electrical network is not perfect, current programme mainly adopts the method for the stifled cover of the stifled mudding of fire prevention interface tube to carry out shutoff, often occur to exceed and adapt to the life-span by plugging material, cause overlapping water inlet tube, after ponding freezes, optical cable is produced to extruding, cause optical cable impaired.

Therefore, be necessary to provide a kind of optical cable downlead sleeve pipe plugging material protective device.

summary of the invention:

A kind of optical cable downlead sleeve pipe plugging material protective device, comprise skirt-type main body and the bilateral snap fastener limit of making in the lump with main body.

For after optical cable downlead sleeve pipe injects plugging material, add and load onto this device, can greatly extend plugging material service time, save manpower, material, and reduce the impaired possibility of optical cable.

the accompanying drawing explanation:

Fig. 1 is that optical cable downlead sleeve pipe plugging material protective device master looks schematic diagram.

Fig. 2 is optical cable downlead sleeve pipe plugging material protective device elevational schematic view.

Figure comprises skirt-type main body 1, bilateral snap fastener limit 2.

embodiment:

Please refer to Fig. 1 and Fig. 2, a kind of optical cable downlead sleeve pipe plugging material protective device, comprise skirt-type main body 1 and the bilateral snap fastener limit 2 of making in the lump with main body.

In use, first the utility model is stuck on optical cable, covers plugging material, bilateral snap fastener limit is fixed, optical cable downlead sleeve pipe plugging material sealing cover, under it, is reached to the protection purpose.

For after optical cable downlead sleeve pipe injects plugging material, add and load onto this device, can greatly extend plugging material service time, save manpower, material, and reduce the impaired possibility of optical cable.

Claims (1)

1. an optical cable downlead sleeve pipe plugging material protective device, is characterized in that: comprise skirt-type main body (1) and the bilateral snap fastener limit (2) of making in the lump with main body.
