Problems solved by technology
[0003] At present, this method of welding elongated needles through wires, and then inserting the needles into the holes of the bipolar plate to connect them has the following disadvantages: 1. When the car is working, it is often in a high-temperature environment and there will be bumps and vibrations. After running for a long time, the long needles will loosen or even fall off in the hole of the bipolar plate, which will affect the normal operation of the detector and cannot accurately detect the state of the bipolar plate in the stack

The invention discloses a conductive elastic sheet. The conductive elastic sheet comprises a first plate body and a second plate body. The first plate body and the second plate body are horizontally arranged in the front-back direction. The front end of the first plate body is fixedly connected with the middle part of the rear end of the second plate body. Riveting claws are vertically arranged onthe left and right sides of the lower end of the first plate body. A first through groove is horizontally formed in the middle of the second plate body in the front-back direction. A strip-shaped elastic sheet is arranged in the first through groove. The elastic piece is arranged in the front-back direction. The front end of the elastic piece is connected with the inner wall of the front side ofthe first through groove. The rear end of the elastic piece extends downwards to the position below the second plate body. Extending parts are horizontally arranged at the rear ends of the left end and the right end of the second plate body. Positioning strips are horizontally arranged at the lower ends of the extending parts in the rear direction. The front ends of the positioning strips are bentparts. One end of the conductive elastic sheet is connected with a wire rod of an inspection device in a riveting mode, and the other end of the conductive elastic sheet is clamped in a through groove of a bipolar plate in an inverted buckling mode.
Description
technical field [0001] The invention relates to the field of circuit connectors. More specifically, the present invention relates to a conductive shrapnel. Background technique [0002] At present, the core component of the hydrogen fuel cell in the development of domestic new energy vehicles is the electric stack, which is composed of many bipolar plates stacked together. The bipolar plates are generally made of metal materials, graphite materials or composite materials. . During the working process of the electric stack, it is necessary to install an inspection device to inspect each bipolar plate in the electric stack, the purpose is to monitor the working status of the bipolar plate in real time. Most of the connecting parts between the inspector and the bipolar plate are elongated needles at present. By opening a strip-shaped hole on the bipolar plate, insert a strip-shaped needle into the hole, and then pour glue into it to fix it. The other end of the elongated ne...
