The cable head is the end of the cable, which is connected and fixed to the connecting wire using a metal sheet. The cable head is a device that must be used in the transmission line to connect the various lines into a whole. Usually, the cable structure joint at the end of the line is called the terminal head. In order to ensure the safety of the transmission lines, facilities and personnel, the cable terminal head has high requirements for dustproof, waterproof and vibration-proof properties.

[0003] The existing cable head insulation glue reinforced cable has poor insulation and weak connection strength when in use, resulting in poor power transmission capacity. In addition, in later use, the connection between the two cables is not tight enough, and the cable body will bend and break when pulled. The inner wall of the connecting device does not fit well with the outer surface of the cable body. Long-term burial underground makes it difficult to resist the intrusion of water vapor. Therefore, a cable head insulation glue reinforced cable was introduced. Utility Model Content

[0025] The housing assembly 3 includes a first half tube 31, with fixing rings 32 fixedly connected to both sides of the first half tube 31, a second half tube 33 provided on the top of the first half tube 31, the first half tube 31 and the second half tube 33 are connected by a hinge, a glue injection port 34 is provided at the top center position of the second half tube 33, a sealing cover 35 is provided on the inner wall of the glue injection port 34, a fixing bracket 36 is fixedly connected to the top of the fixing ring 32, a locking rod 37 is rotatably connected to the inner side of the fixing bracket 36, and a connector 38 is provided in the inner cavity of the first half tube 31.

[0026] The fastening assembly 2 includes two symmetrically arranged tightening assemblies, and the two tightening assemblies are fixedly connected by the housing assembly 3;

[0027] The tightening assembly includes a fastening nut 21, the outer surface of which is provided with a plurality of fixing grooves 23, the inner wall of the fastening nut 21 is provided with a fastening tube 24, the outer surface of the fastening tube 24 is provided with an external thread 25, the outer surface of the fastening tube 24 is provided with a movable opening 26, and an internal thread 22 is provided at the intersection of the inner wall of the fastening nut 21 and the external thread 25.

[0028] The cable assembly 1 includes two symmetrically arranged cable mechanisms, which are connected via a connector 38;

[0029] The cable structure includes a conductor 11 , a filler 12 is sheathed around the outer periphery of the conductor 11 , and an outer sheath 13 is sheathed around the outer periphery of the filler 12 .

[0030] Among them, the outer diameter of the locking rod 37 is consistent with the width of the fixing groove 23, and the fastening tube 24 is gradually tightened by rotating the fastening nut 21; after the equipment is installed, the connection between the locking rod 37 and the fixing groove 23 can avoid the problem of the locking rod 37 and the fixing groove 23 becoming loose after a long period of use.

[0031] Among them, the fastening tube 24 is composed of two half tubes, which are connected by a hinge, and the inner wall of the fastening tube 24 is made of silicone material; in this way, when the cable assembly 1 is placed, the cable assembly 1 and the inner wall of the fastening tube 24 can fit more closely to avoid gaps.
