Abstract
A ground wire grounding terminal convenient to disassemble comprises a fixing end and a movable end, the fixing end is fixed to a wire concrete rod, and a tail part of the movable end is connected with a ground wire; the movable end is composed of a ground wire connecting rod and a fixing bolt, a tail part of the ground wire connecting rod is connected with the ground wire, an upper part of the ground wire connecting rod is connected with one end of the fixing bolt, and the fixing bolt is provided with a nut; and an upper part of the fixing end is provided with a connect hole, and the aperture of the connecting hole matches the outer diameter of the fixing bolt. The ground wire grounding terminal is simple in structure and convenient to use, and working efficiency is greatly improved. When the ground wire grounding terminal is used, the nut at the movable end needs to be loosened only, so that the fixing bolt at the movable end can be separated from the connecting hole in the fixing end.
Description
Technical field
The utility model belongs to electric power facility technical field, relates in particular to a kind of ground wire grounded end.
Background technology
Power supply ground wire: draw backbone from transformer neutral point ground connection, according to standard, at interval of 20-30 rice iterative earthing, play safeguard protection effect in circuit.The in the situation that of electric leakage, electric consumer and ground wire have formed a parallel circuits.Had ground wire, because the resistance of ground wire is smaller, electric current can flow into rapidly the earth, makes electric consumer avoid getting an electric shock.
Current ground wire grounded end has two kinds: one, stiff end is provided with internal thread fixing hole, and the fixed terminal of ground wire front end is provided with external screw thread, fixed terminal and stiff end is threaded, and screws down for fixing; Two, stiff end is provided with adjustment screw, and movable end is set in to adjust on screw and carries out crimping connection.
Above two kinds of earth terminals, removing is not easily, the first, needs completely be back-outed fixed terminal just can change ground wire; The second, need to all back-out and just movable end can be taken out adjusting screw.
Utility model content
To be solved in the utility model is to dismantle inconvenient technical problem for existing earth terminal, and a kind of easy-to-dismount ground wire grounded end is provided.
In order to solve above technical problem by the following technical solutions: a kind of easy-to-dismount ground wire grounded end, comprise stiff end and movable end, stiff end bottom is fixed on electric wire cement pole, and movable end afterbody connects ground wire; Movable end is comprised of ground wire connecting rod and set bolt, and ground wire connecting rod afterbody is connected with ground wire, and ground wire connecting rod top is connected with set bolt one end, is provided with nut on set bolt; The top of stiff end is provided with connecting hole, matches with the external diameter of set bolt in the aperture of connecting hole.
The aperture of connecting hole be greater than set bolt external diameter, be less than the external diameter of nut.
The other end of set bolt is provided with lockhole.
Described stiff end is rectangle iron plate, one side being fixed on concrete wire pole and ground connection of rectangle iron plate, rectangle iron plate is provided with U-shaped opening as connecting hole, and the width of U-shaped opening is greater than the external diameter of set bolt, is less than the external diameter of nut.
The oblique top of U-shaped opening, be 45 ° of angles with the base of rectangle iron plate.
The utility model is simple in structure, easy to use, has greatly improved operating efficiency.During use, only need to become flexible the nut of movable end, make the set bolt of movable end can depart from the connecting hole of stiff end.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model stiff end.
Fig. 2 is the structural representation of the utility model movable end.
Embodiment
As shown in Figure 1, 2, a kind of easy-to-dismount ground wire grounded end, comprises stiff end and movable end, and stiff end bottom is fixed on electric wire cement pole, and movable end afterbody connects ground wire.
Movable end is comprised of ground wire connecting rod 4 and set bolt 5, and ground wire connecting rod 4 afterbodys are connected with ground wire 8, and ground wire connecting rod 4 tops are fixedly connected with set bolt 5 one end, and the other end of set bolt 5 is provided with lockhole 7, is provided with nut 6 on set bolt 5.Stiff end is rectangle iron plate 1, one side of rectangle iron plate 1 is fixed on concrete wire pole 3 and ground connection, rectangle iron plate 1 is provided with U-shaped opening as connecting hole 2, and connecting hole 2 matches with set bolt 5, and the width of U-shaped opening is greater than the external diameter of set bolt, is less than the external diameter of nut.The oblique top of U-shaped opening, be 45 ° of angles with the base of rectangle iron plate.
