Description
Technical field
The present invention relates 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 electric energy meter related in transformer station every year
During meter, need to seal in secondary measurement current loop by connecing in the electric current of tester, improving 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, the contact of point face, misses
Difference is larger, and contact is not sacrifices consisting of an ox, a sheep and a pig;
2nd, the plastic cap nut guarantee contact of current plug rear end need to be tightened every time, waste time and energy;
3rd, commonly use current plug time length and not only damage oneself, and electric current plug jack also can be caused to damage.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of interpolation external clamping current testing wire clamp, also will not be hardly damaged
Electric current plug jack is caused damage, easy-to-connect, water conservancy diversion effect is good.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of interpolation external clamping current testing wire clamp, including current plug and alligator clamp, described alligator clamp include maxillary, under
Jaw, rotary shaft, outer clip and hand part, described current plug afterbody is fixing on the rotary shaft, and described maxillary and lower jaw are clipped in electric current
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 includes positioned at the hollow copper pipe of internal layer and is arranged on the rubber insulation on hollow copper pipe surface, hollow copper pipe interior
Footpath is 4, and external diameter is 5.
Further, described outer clip rear end is bent outwardly.
Further, it is movably installed with expansion rod in the described current plug of institute, expansion rod runs through current plug end face, expands
Bar bottom is provided with compression spring.
Preferably, the head of described current plug and alligator clamp front end length are 5mm~8mm.
Preferably, the maxillary of described alligator clamp and lower jaw opening are away from for 4mm~5mm.
Further, described maxillary and lower jaw are semicircle, and maxillary and lower jaw outer surface are provided with insulating barrier.
The invention has the beneficial effects as follows:
1) current plug is fastened by alligator clamp, itself is hardly damaged and also electric current plug jack will not be caused to damage;
2) fastened by alligator clamp, easy and simple to handle, 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 is good.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, it is a kind of interpolation external clamping current testing wire clamp, including current plug 1, alligator clamp,
Described alligator clamp includes maxillary 2, lower jaw 3, rotary shaft 4, outer clip 5 and hand part 8, and described current plug 1 afterbody is fixed on rotation
On axle 4, described maxillary 2 is clipped on current plug 1 face of cylinder with lower jaw 3, certainly, is movably installed with swollen in described current plug 1
Expander roll 6, expansion rod 6 runs through current plug 1 end face, and expansion rod 6 bottom is provided with compression spring 7, the top rounding of attaching plug 1
Angle, during attaching plug 1 insertion jack, expansion rod 6 declines, and extrudes attaching plug 1, and attaching plug 1 is bigger with jack contact area,
Rotary shaft 4 two ends connect alligator clamp.
Maxillary 2 rear end face is provided with outer clip 5, and lower jaw 3 rear end is provided with hand part 8, and 8 points of hand part is included positioned at internal layer
Hollow copper pipe and the rubber insulation being arranged on hollow copper pipe surface, the internal diameter of hollow copper pipe is 4, and external diameter is 5, described outer
Press from both sides 5 rear ends to be bent outwardly, be bent outwardly and make when using this testing wire clamp, convenient operation, outer clip 5 is used cooperatively with hand part 8,
Testing wire clamp is fixed on rosette jack.
As shown in Figures 2 and 3, the head of described current plug 1 and alligator clamp front end length are 5mm~8mm, described crocodile
