Abstract

The invention relates to an auxiliary device used in a debugging process of a circuit breaker, in particular to a tool for debugging the circuit breaker. The tool for debugging comprises a mother rod and at least one pair of clamping arms assembled on the mother rod in an articulating manner, wherein articulating axes of the two clamping arms are arranged at an interval in an extension direction of the mother rod and are parallel; each clamping arm is divided into a clamping part and a handle part by taking an articulating point of each clamping arm and the mother rod as the boundary; conductive contacts are fixedly assembled on the clamping parts; and elastic pulling pieces are arranged between the mother rod and the clamping parts of the clamping arms. In a using process, the conductive contacts on the clamping arms are connected by a lead wire, then the clamping parts of the two clamping arms are stretched and inserted into two corresponding contact arms of the circuit breaker respectively by holding the handle parts of the clamping arms, the clamping arms are released at this time, and then the clamping arms can be automatically clamped on the two contact arms of the circuit breaker by the action of the elastic pulling pieces. Therefore, the manpower required for debugging the circuit breaker can be reduced, and the labor cost for debugging the circuit breaker can be lowered.

Description

Circuit breaker debugging frock

Technical field

The present invention relates to the servicing unit of using in circuit breaker debug process, particularly a kind of circuit breaker debugging frock.

Background technology

In order to guarantee to greatest extent precision and performance function, circuit breaker need to be debugged before dispatching from the factory or while installing.In debug process, need by wire, its two corresponding contact arms are electrically connected and on wire, are connected in series battery and indicator light.In prior art, when circuit breaker is debugged, being connected between its corresponding two contact arms and wire is all to realize by artificial, because the time that debugging is required is generally not long, therefore being connected between wire and corresponding contact arm adopts hand by the mode of wire often, so, because needs are pressed wire, a people obviously cannot complete debugging work, when circuit breaker is debugged, often need special messenger to keep contacting between wire and corresponding contact arm, this has obviously caused great waste of human resource, improved the required cost of debug circuit breaker.

Summary of the invention

The object of the present invention is to provide a kind of circuit breaker debugging frock, to reduce the required manpower of debug circuit breaker, reduce the cost of labor of debug circuit breaker.

In order to address the above problem, circuit breaker of the present invention is debugged by frock by the following technical solutions: circuit breaker debugging frock, comprise female bar and hinge mounted at least one pair of jig arm on female bar, with the hinge axes of two a pair of jig arm, along the bearing of trend interval of female bar, arrange and parallel to each other, each jig arm all take that it is divided into clamping part and shank with the pin joint of female bar separately as boundary, on described clamping part, be fixedly equipped with conductive contact, between female bar and the clamping part of jig arm, be provided with elasticity drawing piece.

With two a pair of jig arm, each pin joint place since itself and female bar bends to the other side.

Each jig arm makes the angle forming between its clamping part and shank between 90-120 ° after bending.

Shank length sum with two a pair of jig arm equals the distance between this two jig arm and the pin joint of female bar.

Shank with two a pair of jig arm is equal in length.

Along bearing of trend separately, be laid with two above hanging parts corresponding with elasticity drawing piece on the clamping part of jig arm and/or on female bar.

Elasticity drawing piece is extension spring or elastic rope.

Elasticity drawing piece is extension spring, is coated with pole in extension spring.

With connecting by wire between two a pair of jig arm, on described wire, be serially connected with battery case and indicator light.

Because this circuit breaker debugging comprises female bar and hinge mounted at least one pair of jig arm on female bar by frock, with the hinge axes of two a pair of jig arm, along the bearing of trend interval of female bar, arrange and parallel to each other, and each jig arm all be take, and it is divided into clamping part and shank with the pin joint of female bar separately as boundary, on clamping part, be fixedly equipped with conductive contact, between female bar and the clamping part of jig arm, be provided with elasticity drawing piece, so can first the conductive contact with in a pair of jig arm be connected by wire in use, then by controlling the shank of jig arm, make open and be inserted into respectively in two corresponding contact arms of circuit breaker with the clamping part of two a pair of jig arm, now unclamp jig arm, it will be held on two contact arms of circuit breaker by automatic clamp under the effect of elasticity drawing piece, just can ban the mode of manually pressing thus, reduce the required manpower of debug circuit breaker, reduce the cost of labor of debug circuit breaker.

Further, after jig arm bending, can reduce the volume of this frock, also be convenient to one-handed performance simultaneously; Making the angle that forms between clamping part and shank between 90-120 ° and making shank with two a pair of jig arm equal in length is also for the ease of one-handed performance, two above hanging parts corresponding with elasticity drawing piece are set are for traction force and tractive stroke that can adjustable elastic drawing piece, make this frock be applicable to the circuit breaker of different model; Adopt the extension spring can proof strength and traction force as elasticity drawing piece, adopt elastic rope to be conducive to reduce costs as elasticity drawing piece; Pole is for preventing jig arm excess shrinkage when not working.

Embodiment

The embodiment of frock for circuit breaker debugging, as shown in Figure 1-2, this frock comprises female bar 101 and the hinge mounted jig arm 102 on female bar, in the present embodiment, jig arm 102 has a pair of, their hinge axes arranges along the bearing of trend interval of female bar 101 and is parallel to each other, each jig arm 102 all take that it is divided into clamping part 11 and shank 12 with the pin joint of female bar 101 and separately from the pin joint bending of itself and female bar 101 as boundary, two jig arm 102 are all to another bending, equal in length and their the length sum of the shank of two jig arm 102 equals the distance between this two jig arm and the pin joint of female bar 101, each jig arm 102 makes the angle forming between its clamping part 11 and shank 12 between 90-120 ° after bending, in the present embodiment, this angle is 100 °, on clamping part, be fixedly equipped with conductive contact 103, between female bar 101 and the clamping part of jig arm 102, be provided with elasticity drawing piece 104, in the present embodiment, on the clamping part of each jig arm, along its bearing of trend, be laid with two hanging parts corresponding with elasticity drawing piece 105, elasticity drawing piece 104 is extension spring, in extension spring, be coated with pole.In addition, in the present embodiment, between two jig arm, by wire, connect, on described wire, be serially connected with battery case and indicator light (not shown).

During use, can by hold female bar 101 and two jig arm 102 shank so that the clamping part of two jig arm open, then the conductive contact on clamping part 103 is inserted in the contact arm 106 of circuit breaker, after loosing one's grip, jig arm will be ordered about conductive contact 103 and reliably be contacted with the corresponding contact arm of circuit breaker under the effect of elasticity drawing piece 104.

In circuit breaker debugging, with in other embodiment of frock, the quantity of jig arm can also be for more than two pairs, and the hinge axes of every two a pair of jig arm and female bar should be parallel to each other; Elasticity drawing piece can also be elastic rope.
