Abstract
The utility model relates to a novel compressed spring type electric power fastener. Its technical scheme is: including last clamp, lower clamp and back shaft, go up the clamp and pass through back shaft swing joint down between the clamp, last clamp include the handle, support to press from both sides and the coalesced copper is zinc -plated presss from both sides mouthful, supports one side connection handle who presss from both sides, the opposite side is connected coalesced copper zinc -plating and is pressed from both sides mouthful, the clamp includes handle, a copper column sleeve section of thick bamboo, compression spring and coalesced copper post down, the telescopic inner chamber of copper post is equipped with compression spring, and the coalesced copper post passes through compression spring to be installed at copper column sleeve section of thick bamboo inner chamber, and the telescopic left end of copper post is the handle. The beneficial effects are that: carry out the cross -over connection or when the earth connection on air switch, can be more convenient, swift, the safe operates, press from both sides through coalesced copper zinc -plating and mouthful can tightly vise air switch, through the coalesced copper post can with the contact tightly of metal screw, the circumstances of having avoided the short circuit that causes because of contact failure or having opened circuit has improved the security of work efficiency and work greatly.
Description
Technical field
This utility model relates to a kind of electric power overhaul constructing device, particularly to a kind of novel compressed spring type power line clamp.
Background technology
In the maintenance, test of power system, second power equipment electric discharge, ground connection or connection equipment are often tested by field personnel with crocodile mouth formula wire clamp.And in the PT of transformer station overhauls, for ensureing the person in work and equipment safety, often use the little ground wire of PT secondary side carries out reliable ground to equipment, thus prevents the anti-power transmission of secondary side, and what little ground wire was usually taken is crocodile mouth formula wire clamp.
But, conventional PT secondary side insurance is substituted by present Modular switch, and terminal block is also improved to modular terminal block, traditional earthing clamp (crocodile mouth formula) can exist that card is not in place or the situation of loose contact in this case, and maintenance, the safety of experiment work, accuracy can not get reliable guarantee.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of novel compressed spring type power line clamp, when carrying out bridging on air switch or as earth lead, can be more convenient, fast, the carrying out of safety operates, and substantially increases the safety of work efficiency and work.
Its technical scheme is: include upper clamp, lower clamp and support shaft, it is flexibly connected by support shaft between described upper clamp and lower clamp, described upper clamp includes the zinc-plated jaws of handle, propclip and oxygen-free copper, and the side of propclip connects handle, and opposite side connects the zinc-plated jaws of oxygen-free copper；Described lower clamp includes that handle, copper column sleeve cylinder, compression spring and oxygen-free copper post, the inner chamber of described copper column sleeve cylinder are provided with compression spring, and oxygen-free copper post is arranged on copper column sleeve tube inner chamber by compression spring, and the left end of copper column sleeve cylinder is handle.
The upside of the zinc-plated jaws of above-mentioned oxygen-free copper is arcuate structure, and downside is provided with multiple teeth, and the length of the zinc-plated jaws of oxygen-free copper is more than the length of oxygen-free copper post.
The outer wall of above-mentioned handle, propclip and copper column sleeve cylinder is equipped with silicon rubber insulating sleeve.
The beneficial effects of the utility model are: carry out bridging on air switch or during as earth lead, can be more convenient, fast, the carrying out of safety operates, tightly air switch can be vised by the zinc-plated jaws of oxygen-free copper, by oxygen-free copper post under the action of the spring can with need the metal screws of ground connection contacting tightly, avoid conventional wire clamp situation that is not clamping and that can press from both sides nowhere, it also avoid the situation of short circuit or the open circuit caused because of loose contact, substantially increase the safety of work efficiency and work.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
In upper figure: the zinc-plated jaws of silicon rubber insulating sleeve 1, oxygen-free copper 2, compression spring 3, oxygen-free copper post 4, handle 5, support shaft 6, propclip 7, copper column sleeve cylinder 8, teeth 9.
Detailed description of the invention
In conjunction with accompanying drawing 1, the utility model will be further described:
This utility model includes upper clamp, lower clamp and support shaft 6, it is flexibly connected by support shaft 6 between described upper clamp and lower clamp, described upper clamp includes handle 5, propclip 7 and the zinc-plated jaws of oxygen-free copper 2, and the side of propclip 7 connects handle 5, and opposite side connects the zinc-plated jaws of oxygen-free copper 2；Described lower clamp includes that handle 5, copper column sleeve cylinder 8, compression spring 3 and oxygen-free copper post 4, the inner chamber of described copper column sleeve cylinder 8 are provided with compression spring 3, and oxygen-free copper post 4 is arranged on copper column sleeve cylinder 8 inner chamber by compression spring 3, and the left end of copper column sleeve cylinder 8 is handle 5.
Wherein, the upside of the zinc-plated jaws of oxygen-free copper 2 is arcuate structure, and downside is provided with multiple teeth 9, and the length of the zinc-plated jaws of oxygen-free copper 2 is more than the extension elongation of oxygen-free copper post 4, so that the zinc-plated jaws of the oxygen-free copper of upside 2 can be snapped to the oxygen-free copper post 4 of downside.
It addition, the outer wall of handle 5, propclip 7 and copper column sleeve cylinder 8 is equipped with silicon rubber insulating sleeve 1, only expose the zinc-plated jaws of oxygen-free copper 2 and oxygen-free copper post 4 two parts.
During use, tightly air switch can be vised by the zinc-plated jaws of oxygen-free copper 2, by oxygen-free copper post 4 under the action of the spring with need the metal screws of ground connection contacting tightly, when bridging lead-in wire or earth lead, can quickly, operate reliably, avoid conventional wire clamp situation that is not clamping and that can press from both sides nowhere, it also avoid the situation of short circuit or the open circuit caused because of loose contact.
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as the technical scheme of equivalent by any those of ordinary skill in the art.Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model is claimed.
