Technical field
The present invention relates to isolating switch electrical test field, be specifically related to a kind of isolating switch Mume flower contact Special test wire clamp.
Background technology
At present for the testing wire clamp of breaker loop resistor test, because the structure comparison of Mume flower contact is special, testing wire clamp jaws is too small, and be clipped in Mume flower contact outside, with Mume flower contact metallic member not easily close contact, institute's survey time road resistance value can be caused bigger than normal, therefore need break-in repeatedly; If when being clipped in Mume flower contact side, on the one hand may damage spring because of nip pressure, voltage and current signal adds and is pressed on metallic steel silk spring on the other hand, electric conductivity the conducting electricity very well not as copper of wire spring, may cause measuring producing error; If increase the jaw of wire clamp, make it clamp the periphery of whole Mume flower contact, so greatly will certainly increase the physical dimension of wire clamp, be not easy to storage like this and carry.
Summary of the invention
The invention provides one and extend out formula isolating switch Mume flower contact Special test wire clamp.
The technical solution used in the present invention is: a kind of isolating switch Mume flower contact Special test wire clamp, and tong arm comprises by the first bearing pin cross-articulation upper tong arm together and lower tong arm; Mutually insulated between upper tong arm and lower tong arm, and structure is identical; Upper tong arm comprises clamping part, arc connecting portion and grip part successively; Upper tong arm clamping part is connected with lower pliers head away from arc connecting portion one end; Lower tong arm clamping part is connected with upper grip head away from arc connecting portion one end; Upper grip head is identical with lower pliers head structure; The arc connecting portion that upper tong arm is corresponding with lower tong arm is connected by turn; Upper tong arm clamping part is provided with the second pin-and-hole, and lower tong arm correspondence position is provided with the first pin-and-hole; Upper grip head is rectangular structure, and lateral surface is set to circular arc, for coordinating Mume flower contact inside surface.
Further, described upper grip head outer surface is provided with jagged pincers tooth.
Further, end, described upper tong arm grip part has straight-arm to link up with by the second pinned connection, and end, lower tong arm grip part is provided with links up with straight-arm the draw-in groove matched.
Further, described upper tong arm outside surface is provided with insulation course.
Further, described upper grip head and lower pliers head opposite face length and width are 30mm, and thick is 15mm, and lateral surface arc central angle is 100 °.
The invention has the beneficial effects as follows:
(1) the present invention is the wire clamp extending out formula, by wire clamp expansion with Mume flower contact contact internal walls, can with Mume flower contact inwall close contact, test result is accurate;
(2) the present invention adopts outer arcuate sawtooth binding clip, increases the conductive area with Mume flower contact;
(3) the present invention two tong arm introduces pressure-wire and current line respectively, be easy to test;
(4) tong arm of the present invention is provided with hook, is convenient to carry out carrying and receiving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is binding clip schematic diagram in the present invention.
Fig. 3 is upper grip head vertical view in the present invention.
In figure: 1-1-upper grip head, 1-2-lower pliers head, the upper tong arm of 2-1-, tong arm under 2-2-, 3-turn, 4-first bearing pin, 5-1-first pin-and-hole, 5-2-second pin-and-hole, 6-second bearing pin, 7-straight-arm is linked up with.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Figure 1-3, a kind of isolating switch Mume flower contact Special test wire clamp, tong arm comprises by the first bearing pin 4 cross-articulation upper tong arm 2-1 together and lower tong arm 2-2; Mutually insulated between upper tong arm 2-1 and lower tong arm 2-2, and structure is identical; Upper tong arm 2 comprises clamping part, arc connecting portion and grip part successively; Upper tong arm 2-1 clamping part is connected with lower pliers head 1-2 away from arc connecting portion one end; Lower tong arm 2-2 clamping part is connected with upper grip head 1-1 away from arc connecting portion one end; Upper grip head 1-1 is identical with lower pliers head 1-2 structure; The arc connecting portion that upper tong arm 2-1 is corresponding with lower tong arm 2-2 is connected by turn 3; Upper tong arm 2-1 clamping part is provided with the second pin-and-hole 5-2, and lower tong arm 2-3 correspondence position is provided with the first pin-and-hole 5-1; Upper grip head 1-1 is rectangular structure, and lateral surface is set to circular arc, for coordinating Mume flower contact inside surface; Pin-and-hole on tong arm is respectively used to introduce current line and pressure-wire.
Further, described upper grip head 1-1 outer surface is provided with jagged pincers tooth; The contact area that zigzag striped can increase binding clip and Mume flower contact inwall is set, increases its electric conductivity, thus improve test accuracy.
Further, end, described upper tong arm 2-1 grip part is connected with straight-arm hook 7 by the second bearing pin 6, and end, lower tong arm 2-2 grip part is provided with links up with 7 draw-in grooves matched with straight-arm; In not used time, straight-arm can be linked up with 7 and engage with draw-in groove, be convenient to carrying and receiving of testing wire clamp.
