Because the second pressing part is provided with the machining sharp teeth, the sharpness of the sharp tips of the machining sharp teeth can be ensured, so that the lug can be punctured during extrusion, and the problem of difficult puncturing is solved. The second pressing part with the block structure is convenient for the formation of machining sharp teeth, can increase the number of punctured contact points, and is also suitable for large-current soft package batteries.
Referring to fig. 3 to 5, the current sheet includes a conductive sheet 9 and an elastic sheet 10 that are overlapped, the second pressing portion is fixedly connected to the end portions of the conductive sheet and the elastic sheet, so as to form a connection structure, and the conductive sheet and the elastic sheet are also connected together to achieve the effect of synchronous movement. Wherein, the conducting strip provides sufficient electrically conductive efficiency, and the flexure strip then mainly provides sufficient elasticity when using, when compressing tightly, the bending can be dodged to the electric current piece, and crooked counter-force provides puncture pressure, and after the detection, anchor clamps reset, the flexure strip drives the conducting strip and resets, resumes original state, guarantees stable result of use. Therefore, the current sheet can meet the requirement that the current of a large current flows through the current sheet, can also meet the requirement that the current sheet has a sufficient resetting effect, ensures that the shape of the clamp is stable after extrusion use, and prolongs the service life.
In order to meet the detection requirement of the current sheet, on the premise of thinning preparation, the number of the current sheets is 2, and the two second pressing parts and the first pressing part are of a step-shaped structure which is sequentially arranged, when the current sheet and the voltage sheet are overlapped, the current sheet which is firstly contacted with the tab can block the overlapped current sheets or the overlapped voltage sheets from being extruded due to the fact that the thicknesses of different positions are inconsistent when the current sheet and the voltage sheet are used, and the puncture effect is reduced; when the structure is in a step-shaped structure, the bending degree of each part is different, and the parts are arranged in sequence without drag obstruction.
In order to further improve the puncture effect, one side of the current sheet, which is located at the pressing part, is provided with a comb tooth structure 11, each tooth part of the comb tooth structure is provided with a second pressing part, and each second pressing part has the function of freely adjusting the height in the transverse direction, so that the pressing position is automatically adjusted and corrected, and the puncture effect of each second pressing part in use is ensured.
The first pressing part is of a sheet structure, the sawtooth teeth 8 are arranged on the side edge, the detection requirement can be met, and the processing cost is reduced.
In an embodiment, the structure of the first fastening portion may also be identical to the structure of the second fastening portion.
The fixed seat is provided with a positioning column 12 and a locking hole 13, positioning holes 131 are formed in the electric pressing sheet and the current sheet corresponding to the positioning column, the positioning column and the positioning holes are matched for limiting, and during assembly, the assembly position precision and convenience of the electric pressing sheet and the current sheet can be guaranteed through the positioning column; the electric pressing plate and the current plate corresponding to the lock hole are respectively provided with an avoiding hole 14, the electric pressing plate and the current plate are fixed on the fixed seat through a pressing plate 15, the pressing plate is provided with a locking screw 16, and the locking screw penetrates through the avoiding hole to be connected with the lock hole. Fixed through the clamp plate, simple structure, fastening effect is good.
The tail end of the voltage sheet and the tail end of the current sheet are arranged in a staggered mode and are connected with the fixed seat through a connecting screw 19. The effect of mutual non-influence is achieved.
Specifically, be provided with on the fixing base and place recess 17, electric pressure piece and electric current piece setting still are provided with division board 18 in placing the recess, and the division board setting further reaches the separation effect between the tail end of electric pressure piece and the tail end of electric current piece. And the placing groove is matched with the pressing plate, so that the assembling efficiency is improved.
In an embodiment, referring to fig. 6, a sinking surface 20 and an isolation raised platform surface 21 are disposed in the placing groove, and the design of the sinking surface and the isolation raised platform surface facilitates the insulation between the voltage sheet and the current sheet, i.e. a bin-type design is realized, and the structure is simple and direct.
In one embodiment, referring to fig. 7 to 9, in order to further improve the piercing effect, a bending portion 22 is provided on the current sheet, and the bending portion bends the current sheet and separates the end portion of the current sheet from the end portion of the voltage sheet. Because the existence of the portion of bending during the use for also become certain contained angle A between the tip of current piece and the utmost point ear that needs pierce, the piercing face of second pressfitting portion becomes certain angle with utmost point ear promptly, when second pressfitting portion and utmost point ear contact, the first side contact utmost point ear and exert pressure with the second pressfitting, the contained angle that forms between current piece and the utmost point ear is offset by the bending gradually afterwards, the piercing face of final second pressfitting portion can be whole and utmost point ear contact, the crooked few problem of contact surface between second pressfitting portion and the utmost point ear that leads to when increasing sticiss.
The current sheet comprises a conducting sheet and an elastic sheet which are arranged in an overlapping mode, a wave-shaped extension part 24 is arranged on the conducting sheet or the elastic sheet far away from the conducting sheet, and the arrangement position is mainly determined by the stacking position of the conducting sheet and the elastic sheet.
