Description
Technical field
This utility model is related to wire clamp technical field, more particularly to a kind of interpolation external clamping current testing wire clamp.
Background technology
Electric company needs periodically to carry out school inspection work, electric energy in verification transformer station to related electric energy meter in transformer station every year
During meter, need to connect in the electric current by tester and seal in secondary measurement current loop, to improve verification accuracy, it is therefore desirable to
Using current plug, existing current plug has the disadvantage that：
1st, the tip portion that current plug swells, with an inner face for contact form pick-up current jack, that is, puts face contact, by mistake
Difference is larger, contacts not sacrifices consisting of an ox, a sheep and a pig；
2nd, the plastic cap nut that need to tighten current plug rear end every time just can guarantee that contact, waste time and energy；
3rd, commonly use current plug time length and not only damage oneself, and electric current plug jack can also be caused to damage.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of interpolation external clamping current testing wire clamp, is hardly damaged
Will not electric current plug jack be caused to damage, easy-to-connect, water conservancy diversion effect are good.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of interpolation external clamping current testing wire clamp, including current plug and alligator clamp, the alligator clamp include maxillary, under
Jaw, rotary shaft, outer clip and hand part, the current plug afterbody are fixed on the rotary shaft, and the maxillary is clipped in electric current with lower jaw
On the plug face of cylinder, outer clip is arranged on maxillary rear end face, and outer clamp surface is provided with rubber insulation, and lower jaw rear end is provided with handss and pinches
Portion, hand part include the hollow copper pipe and the rubber insulation installed in hollow copper pipe surface positioned at internal layer, hollow copper pipe it is interior
Footpath is 4, and external diameter is 5.
Further, the outer clip rear end is bent outwardly.
Further, expansion rod is movably installed with institute's current plug, and expansion rod runs through current plug end face, expansion
Bar bottom is provided with compression spring.
Preferably, the head of the current plug is 5mm～8mm with alligator clamp front end length.
Preferably, the maxillary of the alligator clamp and lower jaw opening are away from for 4mm～5mm.
Further, the maxillary is provided with insulating barrier with lower jaw for semicircle, maxillary and lower jaw outer surface.
The beneficial effects of the utility model are：
1) current plug is fastened by alligator clamp, itself is hardly damaged and also will not electric current plug jack be caused to damage；
2) fastened by alligator clamp, easy to operate, easy-to-connect；
3) outside of half cambered surface pick-up current jack of the maxillary of alligator clamp and lower jaw, water conservancy diversion effect are good.
