Description

Technical Field

[0001] This utility model relates to the field of battery wire testing fixture technology, specifically a battery wire testing fixture. Background Technology

[0002] Battery wire testing is a process of verifying the electrical safety and performance of battery connection harnesses using a specialized fixture. After the operator places the wires into the fixture's positioning slot, the pressing mechanism drives the test probes to contact the terminals. The tester automatically injects signals and collects data, completing four core tests—continuity, short circuit, insulation resistance, and milliohm-level resistance—within 50ms. The results are displayed in real time via indicator lights, ensuring that there are no open circuits, misconnections, leakage, or abnormal voltage drops in the wires. This fundamentally eliminates the risk of battery overheating and fire caused by connection failures and is a core quality inspection step to ensure the safety of power battery packs.

[0003] Current performance testing of lead-type batteries largely relies on manual operation, requiring both hands to separate the leads and press them to the test points, which is inefficient and results in inconsistent pressure. Tester fatigue can easily lead to poor contact and low first-pass yield. Manual operation is difficult to adapt to the needs of high-speed production lines. Therefore, we propose a battery lead-type testing fixture. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A battery wire testing fixture includes a base plate 1, a front acrylic plate 12 mounted on top of the base plate 1, two side acrylic plates 4 mounted on the rear end of the front acrylic plate 12, a cylinder fixing plate 8 mounted on the rear end of the side acrylic plates 4, a cylinder fixing block 9 mounted on top of the cylinder fixing plate 8, an electric push rod 10 mounted on the front end of the cylinder fixing block 9, an urethane adhesive fixing seat 11 mounted on the output end of the electric push rod 10, an urethane adhesive 14 fixedly mounted below the urethane adhesive 11, a copper block fixing seat 2 mounted below the urethane adhesive 14, a test copper block 3 mounted inside the copper block fixing seat 2, a sensor 13 mounted on the front end of the copper block fixing seat 2, a bakelite board box 5 mounted on the rear end of the cylinder fixing plate 8, a selector switch 6 mounted inside the bakelite board box 5, a relay 15 mounted on the left side of the bakelite board box 5, a 24V power supply 16 mounted inside the bakelite board box 5, and a foot switch 7 mounted on one side of the bakelite board box 5.

[0021] In this implementation plan: by setting a foot switch 7 and a sensor 13 to control the operation of the electric push rod 10, the battery wires are automatically pressed together, reducing the workload of the tester and improving the testing efficiency of the battery wires; at the same time, by setting a foot control mode and a sensor control mode, the tester can switch between different control modes according to the usage requirements. The dual modes work together to enable the fixture to meet the conflicting requirements of flexible production and high-speed mass production.

[0022] Furthermore:

[0023] In an optional embodiment, the urethane 14 moves up and down on the copper block mounting base 2 via the urethane mounting base 11 and the electric push rod 10.

[0024] In this implementation scheme: when the urethane 14 moves downward, it can press the battery wire onto the test copper block 3. The urethane 14 has a certain deformation capability, which plays a buffering role and makes it easy to press battery wires of different sizes onto the test copper block 3.

[0025] Furthermore:

[0026] In an optional embodiment, the 24V power supply 16 is electrically connected to the foot switch 7 and the sensor 13, the selector switch 6 is electrically connected to the foot switch 7 and the sensor 13, the selector switch 6 is electrically connected to the relay 15, and the relay 15 is electrically connected to the electric push rod 10.

[0027] In this implementation scheme, the foot pedal control mode and the sensor control mode can be switched at will via selector switch 6.

[0028] Furthermore:

[0029] In an optional embodiment, the base plate 1 is fixedly connected to the copper block fixing seat 2, and the urethane adhesive 14 and the test copper block 3 are on the same vertical plane.

[0030] In this implementation plan: when the urethane adhesive 14 moves downward, it can be precisely pressed onto the test copper block 3.

[0031] Furthermore:

[0032] In an optional embodiment, the upper surface of the test copper block 3 is provided with elastic conductive contacts.

[0033] In this implementation plan, the contact between the battery wires and the test copper block 3 is made more stable.

[0034] Working principle: When using this battery wire testing fixture, first, the 24V power supply 16 is turned on. The control mode is switched using selector switch 6 (model: A165E-T2M). When switched to foot control mode, the battery wire is placed on the test copper block 3 inside the copper block holder 2. Then, the foot switch 7 is pressed, which energizes relay 15, causing the electric push rod 10 to move the urethane rubber holder 11 and the urethane rubber 14 below it downwards a certain distance, pressing the battery wire onto the test copper block 3. The test copper block 3 is electrically connected to the tester, allowing the tester to work with the test copper block 3 to test the battery wire. Secondly, when switched to inductive control mode... The tester places their hand on the copper block holder 2. Sensor 13 is an infrared or photoelectric sensor. When sensor 13 detects the tester's hand, relay 15 controls electric push rod 10 to push urethane holder 11 and the urethane 14 below it upward a certain distance. Then, the battery wire is placed on the test copper block 3. The tester then removes their hand. When sensor 13 no longer detects the tester's hand, relay 15 controls electric push rod 10 to push urethane holder 11 and the urethane 14 below it upward a certain distance, pressing the battery wire onto the test copper block 3. The tester then uses the test copper block 3 to test the battery wire. This is the working principle of the battery wire testing fixture.
