Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
As shown in Figure 1-2, test contact of the present utility model comprises a left side, right two contact body 1 and a support left side, the back-up block 6 of right two contact body, contact body 1 is semi-circular shape, most circle or not a half annular, by front, contact body is fixed on the top of back-up block 6 by latter two connecting portion 7 and bolt 4, with nut 3 clamping screw, front connecting portion 7, rear connecting portion 7 is tangent or crossing with the two ends of contact body 1 respectively, connecting portion 7 contact body 1 can be split type, also can be integral type, space 9 is left between the inner surface of contact body 1 and the top of back-up block 6.Contact body 1 and connecting portion form by top layer 2 and internal layer 2 ', and the material on top layer 2 is the malleable electric conducting material of tool, and internal layer 2 ' is flexible insulating material, and back-up block 6 is insulating material.Preferred top layer 2 is that the electric conductivities such as copper, gold, silver, aluminium are good and have metal and the nonmetallic materials of certain ductility, and internal layer 2 ' is silica gel and rubber-like insulation flexible material, as acrylonitrile-butadiene rubber, fluorubber, ethylene-propylene rubber etc.The preferred nylon block of back-up block, rubber, glass fiber and its products, and pottery etc. has certain intensity, the material insulated again.
The thickness on preferred top layer is 0.2-1mm; the distortion that contact body top layer can occur to a certain degree so both can have been made when contact body contacts with battery component; increase the contact area of top layer and Electromagnetically solar energy assembly battery case contact; improve the accuracy of test; can make, between contact body with battery case contact, soft contact occurs simultaneously, protective effect is served to battery component.The thickness of internal layer is advisable can support top layer and make top layer can have certain deformability.
Adopt the flexible reasonable non-metal insulating materials such as silica gel strip as internal layer; can while ensureing the insulation property between top layer and back-up block; the flexibility of its material self is utilized to be out of shape together with the top layer of the materials such as copper sheet; increase the contact area between top layer and contact, protection and supporting role are played to top layer.
Retaining space 9 between the internal layer of contact body and the top of back-up block, can meet copper sheet and silica gel strip be out of shape needed for space, extend the useful life of copper sheet and silica gel strip simultaneously.
The cross section of contact body is arranged to circular arc, makes contact body have certain support force and elasticity, ensures that contact body fully contacts with contact, can extend the useful life of copper sheet and silica gel strip simultaneously.
At the top of back-up block, chamfering 8 is set; like this; there is hard friction in when contact body and contact can be avoided to make internal layer compressive deformation and the top of back-up block; protection internal layer; extend the useful life of contact body; increase internal layer and outer field deformation space simultaneously, add the contact area between contact body and contact.
By nut, the contact above tester is fixed while bolt, nut are fixedly connected with contact body and back-up block, forms the path of battery component and tester.
Embodiment 1
Adopt thickness be the copper sheet of 0.2-1mm as top layer 2, adopt the thick silica gel strip of 5mm-10mm as internal layer 2 ', the material of back-up block 6 is nylon.Copper sheet and silica gel strip are fixed together, and make two isometric bar shapes.Adopt cuboid as back-up block 6, the logical slotted hole 5 of four transverse directions is set on the surface at one of back-up block 6, internal layer and skin are respectively arranged with connecting hole, pass through bolt, two bar shapes are fixedly installed on back-up block 6 by screw rod and slotted hole 5 and connecting hole, and make the two ends of bar shape lay respectively on two apparent surfaces of back-up block 6, like this, bar shape is bent growth semicircular ring, semicircle ring portion is as contact body 1, before, back plane is respectively as front connecting portion 7 and rear connecting portion 7 '. note when bending, the semicircle ring portion of bar shape will leave space 9 with the top of back-up block.
