Detailed Description
To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments.
Referring to fig. 1, the battery clamp for testing battery performance in this embodiment includes two clamping members 10 that are arranged oppositely, and the two clamping members 10 are hinged to each other, and an elastic member is arranged between the two clamping members 10, and the elastic member provides a clamping force for clamping the clamping portions of the two clamping members to each other, and the structural form of the battery clamp can refer to the existing alligator clamp structure, and the positive/negative electrodes of a button cell or a pouch cell are clamped by the clamping force provided by the elastic member, such as a torsion spring 103, during testing, so as to implement the charging and discharging test on the battery.
In one embodiment, referring to fig. 2, the two clamping members 10 are provided with electrical conductors 20 on the clamping portions 101, respectively, and when the two clamping portions clamp a battery to be tested, which is usually a button battery with integrated positive and negative electrodes, the electrical conductors 20 on the two clamping portions can be in contact with the positive electrode and the negative electrode of the battery to be tested, respectively. At this time, the conductors of the two clamping parts are respectively connected to the outer end charging and discharging machine through the leads, so that the charging and discharging test of the battery can be realized.
In this embodiment, the insulating assembly 30 is disposed on at least one of the clamping members 10, and it is usually only necessary to dispose the insulating assembly on one of the clamping members to meet the requirement of use, and the insulating assembly is disposed only on the clamping member located below in fig. 1 as an example. The insulating assembly 30 comprises an insulating member 301 which is movably arranged, of course, the insulating member 301 is made of an insulating material, the movable arrangement refers to direct or relative movable connection between the insulating member and the clamping members, so that the insulating member can move to the position of the clamping part when needed to cover or shield the conductor on one of the clamping parts, and thus when the clamping parts of the two clamping members clamp the positive electrode or the negative electrode of the battery, the conductor 20 on one clamping part can be ensured to be in contact with the positive electrode or the negative electrode of the battery. When testing batteries with separated positive and negative electrodes such as the soft package battery, the two battery clamps are adopted to respectively clamp and connect the positive electrode and the negative electrode of the battery, and the two battery clamps are respectively connected to the charge and discharge machine through the wires connected to the two battery clamps, so that the charge and discharge test of the soft package battery can be realized.
That is to say, the battery clamp of adopting above-mentioned structure is when carrying out the charge-discharge operation to the battery of isostructure, only needs the position of adjustment battery clamp upper insulation part, need not change the battery clamp or change the test that the mode of connection on the battery clamp just can be applicable to the isostructure battery again, fine solution the problem that current battery clamp exists in the testing process, can improve efficiency of software testing to a great extent. Meanwhile, on the basis of the existing battery clamp structure, only one movably connected insulating part is added, so that the overall structure is simpler, the use and the operation are more convenient, and the problem of safety possibly caused by misoperation in the test operation process can be avoided to a great extent.
In one embodiment, for the movable connection structure of the insulating member, the insulating member 301 and the clamping member 10 can be connected by a sliding fit, so that the insulating member 301 can slide along the longitudinal direction of the clamping member in a plane parallel to the upper surface of the electric conductor. Therefore, the insulation piece can be conveniently moved to the upper surface of the electric conductor through the sliding fit structure between the insulation piece and the clamping piece to cover the corresponding electric conductor, and the insulation piece can be slid back to the initial position when the insulation piece does not need to be covered.

Thus, when the insulating part rotates to the position above the upper surface of the corresponding conductor, the corresponding conductor is covered, and when the insulating part does not need to be covered, the insulating part rotates to the initial position.
In one embodiment, as an improvement on the structure of the insulation assembly, the insulation assembly 30 includes a receiving frame 302 disposed on the clamping member near the hinge position, a receiving cavity 321 is disposed in the receiving frame 302 and is matched with the insulation member, and the insulation member 301 and the receiving frame 302 are in sliding fit or rotating connection, so that the insulation member can move and be received in the receiving cavity, and the movable connection and the receiving of the insulation member on the clamping member are realized.

Further, in order to conveniently pull out the insulating member 301 from the accommodating frame when needed, the size of the accommodating cavity 321 is designed to be smaller than that of the insulating member 301, so that when the insulating member 301 moves into the accommodating cavity 321, a part of the insulating member 301 can be exposed out of the accommodating frame 302, and thus the insulating member can be pulled out from the accommodating frame through the part exposed out of the accommodating frame, so as to facilitate adjustment of the insulating member.
Referring to fig. 3 and 4, when the insulation member 301 and the receiving frame 302 are connected in a sliding fit manner, the length of the insulation member 301 is greater than that of the receiving cavity 321, so that when the insulation member is received in the receiving frame, one end of the insulation member 301 can be exposed outside the receiving frame. In the insulating assembly with such a configuration, the insulating member 301 and the housing frame 302 can be configured to be closely fitted to each other, and the movement of the insulating member in the housing state or the drawn-out state can be restricted by the frictional force between the insulating member and the housing frame, so that the insulating member can be kept stable in two different use states. In this structure, in order to prevent the insulator from being completely extracted from the receiving frame, a limiting assembly is provided between the insulator 301 and the receiving frame 302, as shown in fig. 5, the limiting assembly may include one set of limiting blocks provided at the opening of the receiving frame and another set of limiting blocks provided at one end of the insulator, so that when the insulator is extracted, the two sets of limiting blocks cooperate to limit the movement of the insulator; of course, the limiting component can also adopt a limiting groove and other similar structures to achieve the same effect.
