Abstract

The embodiment of the invention provides a wiring terminal which comprises a clamping part, a tightening part and a wire, wherein the clamping part is provided with a first clamping piece and a second clamping piece. A first end of the tightening part is electrically connected with each of the first clamping piece and the second clamping piece, one part of the wire is wrapped by the tightening part, the other part of the wire extends out of the second end of the tightening part, and the wire is electrically connected with the tightening part. The clamping part is used for clamping the bipolar plate, the tightening part is used for tightening the wire to tightly wrap the part of the wire in the tightening part, the electric connection relation between the wire and the clamping part in the wiring terminal is simple and reliable, and problems that due to the welding connection mode, the wire is often loosened, and connection is not firm are solved; structural stability of the wiring terminal is improved, and conductivity of the wiring terminal is ensured.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a connection terminal, an inspection insert including the connection terminal, and a fuel cell stack including the inspection insert. Background technique [0002] As a kind of new energy battery, fuel cell has become a research hotspot in the new energy industry. In the fuel cell stack, the bipolar plate and membrane electrode (MEA) that constitute the fuel cell are relatively important components, which play important roles in gas distribution, drainage, heat conduction, and electrical conduction. It is extremely important to study and detect whether the working voltage of the fuel cell is normal. To detect the voltage signal in the working state of the single fuel cell, it is necessary to electrically connect the inspection harness to the conductive bipolar plate. At present, there are various connection forms on the market, but there are many disadvantages at the same ti...
