The earth connection wire clamp
Technical field
The present invention relates to a kind of wire clamp, relate in particular to a kind of earth connection wire clamp.
Background technology
The earth connection wire clamp that uses at present; Be different according to the busbar of high voltage bus and cable; Select with batt joint ground clamp or line-to-ground wire clamp respectively, when in transformer station, using, batt joint ground clamp and line-to-ground wire clamp can not be general on rectangular conductor and round conductor; The wire clamp crimping is insecure, and the earth connection wire clamp is prone to come off when service work.
Summary of the invention
It is firm to the purpose of this invention is to provide the general line ball of busbar and cable in a kind of transformer station, and dismounting is the earth connection wire clamp fast and easily.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of earth connection wire clamp comprises guide rail; The bottom of guide rail has the earth connection hole, it is characterized in that: a side of the bottom of guide rail is designed with down tension disc, is designed with the following pressuring line groove that opening makes progress on the following tension disc; Also have down screw on the following tension disc, the top of following tension disc is designed with tension disc, has the last pressuring line groove that Open Side Down on the last tension disc; Also have screw on the last tension disc, the right-hand member of last tension disc has gathering sill to the right, and gathering sill matches with guide rail; Last pressuring line groove is corresponding with following pressuring line groove; Last screw is corresponding with following screw, and last screw is connected with the transmission action bars with following screw internal thread, and the lower end of transmission action bars has handle hole.
In this structure, the transmission action bars comprises the screw rod body, and the bottom of screw rod body is designed with right-handed thread, and the screw rod upper part of body is designed with left hand thread, and right-handed thread matches with following screw, and left hand thread matches with last screw.
Advantageous effect of the present invention is: owing to adopted the screw rod of band left hand thread and right-handed thread among the present invention, so use when of the present invention, last tension disc and following tension disc compress; Improved operating efficiency, crimping is firm, and contact is reliable; Difficult drop-off, result of use is good.

Fig. 1 is a structural representation of the present invention.
In the accompanying drawing: 1, go up tension disc; 2, go up pressuring line groove; 3, left hand thread; 4, go up screw; 5, gathering sill; 6, right-handed thread; 7, guide rail; 8, earth connection hole; 9, transmission action bars; 10, handle hole; 11, following screw; 12, following pressuring line groove; 13, following tension disc.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
The present invention is as shown in Figure 1, and a kind of earth connection wire clamp comprises guide rail 7; The bottom of guide rail 7 has earth connection hole 8, it is characterized in that: a side of the bottom of guide rail 7 is designed with down tension disc 13, is designed with the following pressuring line groove 12 that opening makes progress on the following tension disc 13; Also have down screw 11 on the following tension disc 13, the top of following tension disc 13 is designed with tension disc 1, has the last pressuring line groove 2 that Open Side Down on the last tension disc 1; Also have screw 4 on the last tension disc 1, the right-hand member of last tension disc 1 has gathering sill 5 to the right, and gathering sill 5 matches with guide rail 7; Last pressuring line groove 2 is corresponding with following pressuring line groove 12; Last screw 4 is corresponding with following screw 11, and last screw 4 is connected with transmission action bars 9 with following screw 11 internal threads, and the lower end of transmission action bars 9 has handle hole 10.
In the present embodiment, transmission action bars 9 comprises the screw rod body, and the bottom of screw rod body is designed with right-handed thread 6, and the screw rod upper part of body is designed with left hand thread 3, and right-handed thread 6 matches with following screw 11, and left hand thread 3 matches with last screw 4.
When the earth connection operation was installed, with the turn clockwise transmission action bars of earth connection wire clamp of insulating bar, last tension disc moved downward, and following tension disc moves upward, and goes up tension disc and following tension disc like this with busbar or cable clamping; When removing the operation of earth connection, be rotated counterclockwise insulating bar, unclamp tension disc and get final product with following tension disc.
