Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, specifically a testing fixture for the wiring sequence of a lithium battery acquisition harness. Background Technology

[0002] Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was developed in 1996, and their safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to lithium-ion batteries.

[0003] Common wire harness continuity testing involves using plugs at both ends of the wire harness for quick insertion and testing. However, for data acquisition harnesses with aluminum busbars, the busbars are dispersed, and there is no dedicated testing fixture to hold them in place. Summary of the Invention

[0004] The purpose of this invention is to provide a lithium battery acquisition harness sequence testing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lithium battery acquisition harness sequence testing fixture includes an acquisition line and a testing fixture, characterized in that: the acquisition line is provided with a P-plug;

[0007] The test fixture is equipped with a P male terminal corresponding to the 11P plug-in;

[0008] The test fixture consists of a 5V power supply, a current-limiting resistor, an LED, and a test probe. The 5V power supply is connected to the test probe and the current-limiting resistor. The current-limiting resistor is connected to the LED, and the LED is connected to an 11P male terminal.

[0009] Furthermore, the acquisition line consists of wiring terminals, aluminum terminals, and aluminum busbars.

[0010] Furthermore, the aluminum busbar is provided with aluminum terminals.

[0011] Furthermore, the aluminum busbar is connected to the 11P plug via a wire.

[0012] Furthermore, the terminal block is connected to the 11P plug-in via a wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device allows for quick testing by simply placing aluminum busbars in their corresponding positions (no precise positioning required). The position of the LEDs corresponding to the aluminum busbars provides a direct indication of whether the wiring sequence is correct. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example 1:

[0019] Please see Figure 1-2 This utility model provides a technical solution:

[0020] A lithium battery acquisition harness sequence testing fixture includes an acquisition line and a testing fixture, characterized in that: the acquisition line is provided with an 11P plug-in 1;

[0021] The test fixture is equipped with an 11P male terminal corresponding to 11P plug-in 1;

[0022] The test fixture consists of a 5V power supply, a current-limiting resistor, an LED, and a test probe. The 5V power supply is connected to the test probe and the current-limiting resistor. The current-limiting resistor is connected to the LED, and the LED is connected to an 11P male terminal.

[0023] To check the correctness of the wiring sequence, a test fixture is designed as follows: a 5V power supply, a current-limiting resistor R, 11 LEDs, test probes, 11-pin male terminal 1 (for acquiring the pins of the 11-pin connectors in the wiring harness), and several wires. During wiring harness testing, the 11-pin connector 1 is plugged in, and the test probes are used to test B0 to B10 respectively. If the wiring sequence is correct, the corresponding LEDs 1 to 11 will light up; otherwise, the order in which the LEDs light up will be incorrect.

[0024] In actual use, the 5V power supply can be obtained from the USB plug. LED1 to LED11 are fixed near the corresponding aluminum bar (terminal) according to the position of the aluminum bar (terminal) when the actual wiring harness is laid out (see the diagram below). When the aluminum bar (terminal) is tested with a test probe, it can be visually identified whether the corresponding LED light is lit, thereby determining whether the wiring sequence is correct.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
