Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wire harness detection, and in particular to a fully automatic loop detection device for a low-voltage wire harness of a new energy battery. Background Art
[0002] The main function of the fully automatic circuit detection device for new energy battery low-voltage wiring harness is to efficiently and accurately detect the connection status and electrical performance of each circuit in the low-voltage wiring harness. It can promptly detect potential problems such as open circuit, short circuit or poor contact in the wiring harness, and ensure the safe and stable operation of the battery system after the wiring harness is put into use.
[0003] In the existing application scenarios of low-voltage wiring harnesses for new energy batteries, a sponge structure with conductive properties is generally used to tighten the wiring harness and ensure smooth power supply. However, over time, this sponge structure will inevitably suffer from wear and damage. Given that the current sponge structure is mainly installed at the designated position of the equipment by gluing or snapping, and most designs contain two sponge structure units, this situation leads to complexity and inefficiency in the replacement process. Specifically, each replacement requires the two sponge structures to be disassembled and reinstalled one by one, which undoubtedly increases the operation steps and reduces the replacement efficiency.

The device can automatically position the two conductive sponges through a corresponding structure in the process of driving a movable base to slide toward a fixed base so that the two conductive sponges clamp the wiring harness, thereby ensuring the stability of the conductive sponges during use. When the movable base is fixed to the base, the two conductive sponges are not put into use, and the corresponding structure cancels the positioning of the disassembly parts and the conductive sponges, thereby facilitating the disassembly of the conductive sponges.

After the two conductive sponges are separated, the copper sheet will also return to its original state with the cooperation of the corresponding structure and be safely separated from the conductive sponge, effectively avoiding the potential safety hazards caused by the conductive sponge being still energized when the conductive sponge is removed.
