Description
Technical Field
The utility model belongs to the technical field of the electrical accessories technique and specifically relates to a preformed armor rod ground connection wire jumper is related to.
Background
The traditional grounding jumper wire is connected with a protection wire by a parallel groove clamp, and a special tool is required to apply standard torsion to a bolt for locking during installation, so that the construction operation is slow, and the construction effect is not visual. Secondly, the cable is clamped by the parallel groove clamp, stress concentration occurs, daily cable shaking is overlapped, the cable is often abraded and stranded at the clamping position of the parallel groove clamp, and the operation safety of a circuit is affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a preformed armor rod ground connection wire jumper, it is simple convenient to install, has obviously reduced static state and dynamic stress on the wire, makes the wire avoid destructive vibration and fatigue, has prolonged the life of cable greatly, and the ground connection is reliable.
In order to realize the above-mentioned purpose, the utility model provides a preformed armor rod ground connection wire jumper, which comprises a body, the body includes preformed armor rod and the linkage segment of tightly holding, the end-fixing of linkage segment has ground terminal, the linkage segment with the juncture of the preformed armor rod section of tightly holding is provided with the installation mark, the preformed armor rod section of tightly holding is helical structure, the length of the preformed armor rod section of tightly holding is not less than 2.5 effective pitches.
Preferably, the body adopts one of aluminum alloy wire, copper alloy wire, aluminium package steel wire.
Preferably, the ground terminal is in pressure connection with the tail end of the connecting section and is made of the same material as the body, and a fixing bolt is fixed at the top end of the ground terminal.
Therefore, the utility model adopts the above structure, one end of the preformed helical grounding jumper wire adopts the preformed helical gripping section with a thread structure, the installation is simple and convenient, the preformed helical gripping section is wound on the cable and can be installed by bare-handed operation, the static and dynamic stress on the wire is obviously reduced, the wire is prevented from destructive vibration and fatigue, and the service life of the cable is greatly prolonged; aluminum alloy wires, copper alloy wires and aluminum-clad steel wires are adopted, so that the product gripping power is improved; the other end is connected with the grounding connection point by adopting a grounding terminal, and the grounding is reliable.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
Examples
Fig. 1 is the utility model relates to a preformed helical grounding jumper structure sketch map, fig. 2 is the structural sketch map of grounding jumper among the prior art, as shown in the figure, a preformed helical grounding jumper, including the body, the body includes that preformed helical type grips section 1 and linkage segment 3, and the tail end of linkage segment 3 is fixed with ground terminal 4, and the juncture of linkage segment 4 and preformed helical type gripping section 1 is provided with erection marker 2, and the installer of being convenient for confirms mounted position. The pre-twisted type gripping section 1 is of a spiral structure, the length of the pre-twisted type gripping section 1 is not less than 2.5 effective screw pitches, the gripping force of the pre-twisted type gripping section 1 is guaranteed to meet the engineering requirements, and no loosening condition occurs after 200-ten-thousand vibration tests. The body adopts one of aluminum alloy wire, copper alloy wire, aluminium package steel wire, and intensity greatly improves the grip. The material of the body is selected according to the material of the surface of the actual protection wire 5 in actual selection, so that the electrochemical corrosion caused by different metals in an electrical environment is reduced, and the service life of products and cables is prolonged in natural environments such as moist and foggy environments. The grounding jumper wire of the embodiment can be applied to steel-cored aluminum alloy wires, aluminum-clad steel stranded wires, hard copper stranded wires, copper-magnesium alloy stranded wires, OPGW optical cables and the like. The grounding terminal 4 is in compression joint with the tail end of the connecting section 3 and is made of the same material as the body, and a fixing bolt 41 is fixed at the top end of the grounding terminal 4 and is used for being connected with a grounding point, so that the connection is stable and reliable.
Therefore, the utility model adopts the above structure kind of preformed armor rods ground connection wire jumper, it is simple convenient to install, has obviously reduced static state and dynamic stress on the wire, makes the wire avoid destructive vibration and fatigue, has prolonged the life of cable greatly, and the ground connection is reliable.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
