As a further improvement of the utility model, the pressure plate is provided with a hook-shaped groove which is positioned below the bolt. The hook-shaped groove is suitable for placing the cable, the cable can be prevented from falling off easily, and the cable is fixed through bolt pressing, so that connection is reliable.
As a further improvement of the utility model, the number of the wire connecting platforms is three, and the wire connecting platforms are uniformly arranged at equal intervals along the outer circumferential direction of the body. The number of the wiring platforms is three, which indicates that any one of the pressing plate devices corresponding to the wiring platforms can be selected for connection, and the main consideration is that which angle of the wiring platform is convenient to install and which angle can be selected, and the assembly convenience of workers is taken as a criterion.
As a further improvement of the utility model, the body is clamped with an insulating sleeve, the outer circumferential direction of the body is provided with a buckle protruding outwards, and the insulating sleeve is provided with a clamping groove matched with the buckle. The insulating cover can prevent that the cable is whole to expose outside, protects the cable and avoids the invasion of external factor, and through buckle and draw-in groove looks joint, simple to operate connects reliably.
As a further improvement of the utility model, the slots are arranged at intervals along the circumferential direction of the outer part of the body, the number of the slots is six, and the slots are arranged at equal intervals at equal angles in a mode that two slots form a group. The mode of so arranging the draw-in groove is favorable to guaranteeing the cooperation of draw-in groove and buckle, and in any one direction of circumference, the pressure that bears is the same all, and can not cause the condition that one side assembles very easily, but the another side is difficult to the assembly, guarantees the life of insulating cover effectively.
As a further improvement of the utility model, the insulating sleeve is provided with a concave part matched with the wiring platform and the pressing plate, and the concave part is positioned between the front two clamping grooves and the rear two clamping grooves. This structural design is reasonable, accords with the assembly demand of wiring platform, can effectively increase the structural strength of insulating cover simultaneously.
As a further improvement of the utility model, one side of the body is provided with a tooth-shaped rotation stopping part. The rotation stopping part can prevent the body from reversing and loosening.
The grounding wire fixing device has the advantages of simple structure and reasonable design, and the quick installation and disassembly of the grounding wire are realized through the matching connection of the body and the pressing plate device, so that the maintenance is convenient. The body passes through screw thread portion and cable connection, connect reliably, if will dismantle, then reverse unscrewing can, the terminal board is used for installing the clamp plate device, the clamp plate that is located the clamp plate device passes through screw fixed connection with the terminal board, if want to dismantle, the unscrewing screw can be dismantled, easy operation is convenient, with clamp plate threaded connection's bolt, be used for compressing tightly and fixed earth connection, prevent that the earth connection from droing, this structural design targets in place, connect reliably, also convenient the dismantlement simultaneously, the maintenance operation of being convenient for.
