Description

Ground wire clamp

the

technical field

The invention relates to a wire clamp, in particular to a grounding wire clamp. the

Background technique

The grounding wire clips currently used are based on the difference between the busbar and the cable of the high-voltage bus, and the flat grounding wire clip or the line grounding wire clip are selected respectively. It cannot be used universally on rectangular conductors and round conductors, the crimping of the clamps is not firm, and the clamps of the grounding wires are easy to fall off during maintenance work. the

Contents of the invention

The purpose of the present invention is to provide a grounding wire clip which is used for busbars and cables in a substation, which is reliable in pressing wires and quick and easy to disassemble. the

In order to achieve the above object, the technical solution adopted by the present invention is: a grounding wire clip, including a guide rail, the lower end of the guide rail is provided with a grounding wire hole, and it is characterized in that: a lower pressure plate is designed on one side of the lower part of the guide rail, The lower pressure plate is designed with a lower pressure groove with an opening upward, and a lower screw hole is opened on the lower pressure plate, and an upper pressure plate is designed above the lower pressure plate, and an opening is opened on the upper pressure plate. The upper crimping groove, the upper crimping plate also has an upper screw hole, the right end of the upper crimping plate has a guide groove to the right, the guide groove matches the guide rail, the upper crimping groove corresponds to the lower crimping groove, The upper screw hole corresponds to the lower screw hole, and the upper screw hole and the lower screw hole are internally threaded to be connected with a transmission operating rod, and the lower end of the transmission operating rod is provided with an operating hole. the

In this structure, the transmission operating rod includes a screw body. The lower part of the screw body is designed with a right-handed thread, and the upper part of the screw body is designed with a left-handed thread. The right-handed thread matches the lower screw hole, and the left-handed thread matches the upper screw hole. the

The advantages and effects of the present invention are: because the present invention adopts the screw rod with left-handed thread and right-handed thread, so when using the present invention, the upper and lower pressure plates are pressed tightly, which improves the work efficiency, and the crimping is firm. The contact is reliable, not easy to fall off, and the use effect is good. the

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1, the present invention is a grounding wire clamp, including a guide rail 7, the lower end of the guide rail 7 is provided with a grounding wire hole 8, and its feature is that a lower pressure plate 13 is designed on one side of the lower part of the guide rail 7, The lower pressure plate 13 is designed with a lower pressure groove 12 with an upward opening, and the lower pressure plate 13 is also provided with a lower screw hole 11, and an upper pressure plate 1 is designed above the lower pressure plate 13, and the upper pressure plate 1 is provided with an upper crimping groove 2 with an opening downward, and an upper screw hole 4 is also opened on the upper crimping plate 1. The right end of the upper crimping plate 1 is provided with a guide groove 5 to the right, and the guide groove 5 is connected to the guide rail 7. Cooperate, the upper crimping groove 2 corresponds to the lower crimping groove 12, the upper screw hole 4 corresponds to the lower screw hole 11, the upper screw hole 4 and the lower screw hole 11 are internally threaded with a transmission operating rod 9, and the transmission operating rod 9 The lower end has an operation hole 10.

In this embodiment, the transmission operating rod 9 includes a screw body, the lower part of the screw body is designed with a right-handed thread 6, the upper part of the screw body is designed with a left-handed thread 3, the right-handed thread 6 matches the lower screw hole 11, and the left-handed thread 3 Cooperate with upper screw hole 4. the

When installing the grounding wire, use the insulated operating lever to rotate the transmission operating lever of the grounding wire clamp clockwise, the upper pressing plate moves downward, and the lower pressing plate moves upward, so that the upper pressing plate and the lower pressing plate move the busbar Or cable clamping; when removing the grounding wire, rotate the insulating operating lever counterclockwise to loosen the upper and lower pressure plates. the
