Description
Technical field
It starts to exchange fire wire clamp the utility model relates to a kind of anti-slip electrification, belongs to electrification and start to exchange fire wire clamp technical field.
Background technique
It charges wire clamp of starting to exchange fire to be mainly used for for drainage wire hanging being fixed on firewire, to realize the power supply of firewire and drainage thread
It connects.The existing wire clamp of starting to exchange fire that charges mainly is made of J-type grab, screwing bolts and clamping head, is hung on firewire in J-type grab
Afterwards, by tightening screwing bolts so that clamping head and J-type grab grip firewire jointly, so realize electrification start to exchange fire wire clamp with
The fixation of firewire.
Applicant has found in practical application above structure the prior art has at least the following problems: in long-term use, due to external force, example
As wind get angry line shake, will cause screwing bolts operation loosen so that conductor overheating, security risk is big.
Utility model content
It starts to exchange fire wire clamp technical problem to be solved by the utility model is: providing a kind of anti-slip electrification, it is existing to solve
Screwing bolts run loosening after long-term use in technology, lead to conductor overheating, the technical problem of safety difference.
The technical solution of the utility model is: a kind of anti-slip electrification is started to exchange fire wire clamp, and electrification wire clamp of starting to exchange fire includes:
J-type grab, one side are open end, and the other side is closed end, and the upper end is hook-shaped groove, and lower end is clamping support
Face, the clamping supporting surface have the first screw hole；
Screwing bolts, including top end part and threaded shank, the threaded shank cooperation are threaded through in first screw hole, the top
End is located at the inside of the J-type grab；
Clamping head is fixed at the top end part of the screwing bolts；
The top end face of the clamping head is equipped with cross section thorax line, and the inner wall of the hook-shaped groove is equipped with cross section thorax line.
