Description

Battery connector conversion device

Technical Field

The present invention relates to a terminal switching device, and more particularly, to a battery terminal switching device.

Background

A rechargeable battery is one of electronic devices widely used at present, and the rechargeable battery needs to perform a test operation in addition to a charging operation.

Please refer to fig. 1A and 1B, which are schematic circuit diagrams illustrating a conventional battery charging and testing circuit. Currently, when charging the rechargeable battery B, the two conductive wires are connected to the positive and negative electrodes of the rechargeable battery B by the positive and

negative electrodes

11 and 12 of the charger C. When the rechargeable battery B is tested, four conducting wires are connected to the positive electrode and the negative electrode of the rechargeable battery B by the positive electrode and the

negative electrode

13, 14, 15 and 16 of the testing instrument T.

However, since the test instrument T for testing the rechargeable battery B mostly uses a four-wire structure of Kelvin connection (Kelvin connection) to obtain higher test accuracy, the charger C does not need to use a four-wire structure, but only needs to connect the positive electrode and the negative electrode of the rechargeable battery B by two wires to perform charging. Therefore, when the rechargeable battery B needs to be charged and tested, the two-wire and four-wire sets connected to the rechargeable battery B must be repeatedly removed and replaced during the conversion process of charging and testing, which wastes much time and causes troubles and inconvenience in use.

Accordingly, how to provide a battery tab switching device to improve the above problems has become an urgent issue to be studied.

Disclosure of Invention

In view of the above problems, the present invention provides a battery connector converting device, which includes a housing, a positive terminal, a negative terminal, two positive connectors, and two negative connectors. The positive terminal, the negative terminal, the two positive connectors and the two negative connectors are arranged on the shell. The two positive electrode connectors are respectively connected with the positive electrode ends by two first conducting wires, the two negative electrode connectors are respectively connected with the negative electrode ends by two second conducting wires, and the two first conducting wires and the two second conducting wires are arranged in the shell.

In view of the above, the battery connector switching device of the present invention provides a design of an adapter (adapter), so that a user does not need to repeatedly disassemble and assemble the wire set connected to the battery terminal, but rather fixedly connect the wire set connected to the positive and negative terminals of the battery.

end points

31a, 32a, 31B, and 32B of the wire sets 3a and 3B are kept connected to the positive and negative electrodes of the rechargeable battery B without being removed, and the user only needs to connect the two

negative electrodes
