Description

A battery testing tool

Technical Field

The utility model relates to the technical field of battery testing, in particular to a battery testing tool.

Background technique

After the battery is manufactured, in order to ensure that there are no problems, it is usually necessary to conduct electrical testing to confirm the number of charge and discharge times, internal resistance during charge and discharge, and other data, so as to preliminarily determine whether there are corresponding problems with the quality of the battery. Most batteries have positive and negative contacts. In order to test the battery, it is usually necessary to connect alligator clips or spring terminals to the positive and negative contacts of the battery. Since there are two electrodes, the same operation must be repeated twice, which greatly affects work efficiency.

Utility Model Content

Therefore, in view of the above problems, the utility model proposes a battery testing tool with simple structure and convenient use.

To achieve the above-mentioned purpose, the technical solution of the utility model is to provide a battery testing tool, comprising: a bottom plate, a clamping device arranged on the bottom plate for clamping the positive and negative electrode tabs of the battery at the same time;

The clamping device comprises: conductive springs with a certain width, which are respectively arranged on the left and right sides of the bottom plate, and the conductive springs are electrically connected with electric wires for conducting electricity;

The bottom plate is also provided with a supporting device for raising the conductive spring and playing a supporting role when the positive and negative electrode contacts are inserted into the conductive spring.

A further improvement is that the support device includes: a pad arranged on the bottom plate, the conductive spring is arranged on the front side of the pad so that the folded part in the middle of the conductive spring resists the pad, and the conductive spring is respectively located on the left and right sides of the front end of the pad.

A further improvement is that a heightening plate is provided between the pad and the bottom plate for further adjusting the relative height between the conductive spring and the positive and negative electrode contacts.

A further improvement is that the pad is a bakelite board.

A further improvement is that a handle is also provided on the pad to facilitate the user to move the battery testing tool.

The advantages and beneficial effects of the utility model are:

The structure is simple and easy to use. The test tool can be connected to the positive and negative terminals of the battery at one time, thereby avoiding the need to connect the positive and negative terminals separately and reducing time. The connection method is clamping with a conductive spring, which is convenient for plugging and unplugging. After increasing the width of the conductive spring, it can be adapted to various types of batteries to a certain extent, thereby improving the functionality of the tool.
