Description

Waterproof fire-retardant intermediate head protective housing of cable Technical Field The utility model relates to the technical field of joint protection shells, in particular to a waterproof flame-retardant middle joint protection shell for a cable. Background In modern power transmission systems, cables are used as key electric energy transmission carriers, the safe and stable operation of the cables is crucial, cable intermediate connectors are used as weak links in cable lines, the cables are extremely susceptible to external environment factors such as moisture invasion, mechanical external force impact, fire threats and the like, electrical faults are further caused, and the traditional cable intermediate connector protective shell has obvious defects in the aspect of waterproof performance. Most protective housing only relies on simple buckle to connect, is difficult to effectively block moisture from casing junction and cable penetration department infiltration, and moisture long-term erosion can make cable intermediate head's insulating properties decline, causes serious problems such as short circuit, and buckle connection structure of traditional protective housing often is not firm enough simultaneously, when receiving external force impact or long-term vibration, appears not hard up phenomenon easily, can't provide reliable physical protection for cable intermediate head. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a waterproof flame-retardant middle joint protective shell for a cable, which solves the problem that the buckle connection structure of the traditional protective shell is not firmly sealed. (II) technical scheme In order to achieve the above purpose, the utility model is realized by the following technical scheme: The waterproof flame-retardant middle joint protection shell for the cable comprises a second shell, wherein a connecting lock catch is symmetrically and fixedly connected to the outer wall of the second shell, the waterproof flame-retardant middle joint protection shell further comprises a first shell, the outer wall of the first shell is fixedly connected with the outer wall of one side, far away from the second shell, of the connecting lock catch, the first shell and the second shell are made of PP flame-retardant materials, a pouring opening is formed in the outer wall of the top of the first shell and used for pouring resin AB glue, an exhaust opening is symmetrically formed in the outer wall of the top of the first shell, a rubber plug is slidably connected to the inner wall of the pouring opening, a rubber belt is symmetrically and fixedly connected to the outer wall of the rubber plug, a sealing plug is fixedly connected to the outer wall, far away from one side of the rubber plug, of the rubber belt, and a first sealing ring is symmetrically and fixedly connected to the inner wall of the first shell.
