It should not be understood as indicating or imply relative importance or implicitly indicate the quantity of indicated technical characteristic.It defines as a result,
The feature of " first ", " second " can explicitly or implicitly include one or more this feature.In the utility model
In description, the meaning of " plurality " is two or more, unless otherwise specifically defined.
In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. terms shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
Can also be electrical connection to be mechanical connection；It can be directly connected, can also indirectly connected through an intermediary, Ke Yishi
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
Referring to Fig. 1, it is the stereogram of test fixture 100 provided by the utility model.The test fixture 100 includes
A pair of intermediate clamping piece 10 connected.Each clamping piece 10 includes clamping part 11 and operation portion 12.The clamping part 11 and institute
The junction for stating operation portion 12 is provided with mounting portion 13, and two clamping pieces 10 are connected by mounting portion 13, and two clamping pieces
Position between 10 positioned at mounting portion 13 is additionally provided with torsional spring 20.When the operation portion 12 of two clamping pieces 10 is pressed simultaneously,
Between two clamping parts 11 can be detached so that the pole (not shown) of battery to be tested is positioned over two intermediate plates, and ought it not press
When, two clamping parts 11 clamp pole under the active force of torsional spring 20.
Please in conjunction with referring to Fig.2, the opposite side of the clamping part 11 of a pair of of clamping piece 10 is provided with rectangular groove 111,
And several elastic components 30 are provided in groove 111.Several elastic components 30, which stretch out on one end of the groove 111, to be additionally provided with
Easy to produce the intermediate plate 40 of deformation.One end of several elastic components 30 is contained in the groove 111, and the other end stretches out institute
Groove 111 is stated to flexibly support the intermediate plate 40.In the present embodiment, the elastic component 30 is spring.The intermediate plate 40 is
Metal intermediate plate, it is preferable that the intermediate plate 40 is tin-phosphor bronze intermediate plate.Since tin-phosphor bronze is a kind of alloyed copper, have good
Electric conductivity and elasticity, are not easy to generate heat and ensure to be provided simultaneously with very strong fatigue resistance safely.Therefore, using the folder of tin-phosphor bronze
Piece can guarantee the generation that heat is reduced while contact is good.
Test fixture 100 provided by the utility model is set since clamping part 11 is arranged in fluted 111 and the groove
Several elastic components 30 are equipped with to flexibly support intermediate plate 40, so that when the pole of mesuring battary is between two intermediate plates 40,
Change oneself shape since the effect of elastic component 30 can agree with the curved surface of pole and closely contact with pole, into
And point contact is made to become face contact, the contact area between pole and intermediate plate 40 is increased, to increase test fixture 100
Conveyance capacity improves measuring accuracy.
Please again together refering to Fig. 3, the operation portion 12 of each clamping piece 10 opens up circular first mounting hole 121 and one
Rectangular opening 122.The position of opening 122 on the operation portion 12 of one of clamping piece 10 is installed by one fuse 50.Institute
It states fuse 50 and includes columned ontology 51 and the interconnecting piece 52 being respectively arranged in two circular end faces of ontology 51.Into
One step, the second mounting hole 521 is offered on each interconnecting piece 52.One of them second mounting hole 521 is pacified with described first
It fills hole 121 and matches one fastener of merga pass (for example, bolt) 60, the fuse 50 is mounted on the operation portion 12
On, and another second mounting hole 521 with the power line (conducting wire) in test cabinet for being attached.It is appreciated that by institute
It states fuse 50 to be mounted on the operation portion 12, therefore, different rule can be installed according to different current needs
The fuse 50 of lattice, so it is cost-effective while playing overcurrent protection.
In use, the power line of test cabinet is passed through fuse 50 first the second mounting hole 521 and the operation portion 12
It is attached, then the pole of battery to be tested is positioned between two intermediate plates 40 and is in close contact with two intermediate plates 40, by
In pole be a curved surface, and the intermediate plate have elasticity, therefore, under the action of several elastic components 30,40 meeting of the intermediate plate
Agree with this curved surface and change oneself shape and closely contact with pole, so that point contact is become face contact, increase test
The conveyance capacity of fixture 100.At this point, just completing the connection of test cabinet and battery to be tested, can be tested.Work as test process
When middle appearance causes the electric current by test fixture 100 to become larger suddenly extremely, the fuse 50 will fuse, to disconnect
Electric connection between battery and test cabinet, avoids the generation of safety accident.
The utility model is not only in the description and the implementation described, therefore for the personnel of familiar field
For other advantage and modification is easily implemented, therefore without departing substantially from universal defined by claim and equivalency range
Spirit and scope in the case of, the utility model is not limited to specific details, representative equipment and shown here as with retouch
The diagram example stated.
