Embodiment 1

[0021] Such as image 3 As shown, the voltage acquisition unit 1 is inserted into the guide groove of the metal bipolar plate 6 according to the guide structure 8, and the metal reed in the voltage acquisition unit 1 clamps the inspection structure of the metal bipolar plate 6 (the inspection structure refers to is a detection position of the metal bipolar plate), the spring-type unilateral locking structure 3 locks the fins 12 of the metal bipolar plate to prevent falling off, and the shell unit 2 utilizes the protruding feature 9 of the superimposed self-locking structure and the superimposed self-locking structure The recessed feature 10 of the locking structure realizes the follow-up positioning connection of the shell and prevents missed detection of the metal bipolar plate.

[0022] Such as Figure 5 As shown, the connector guide mechanism 8 is inserted into the guide groove of the metal bipolar plate 6 for guidance, so as to realize accurate positioning with the metal ...

Embodiment 2

[0025] Such as Figure 6 As shown, the first interlocking structure 13 of the first connector and the second interlocking structure 14 of the second connector are locked and positioned to connect with each other, so as to achieve the function of being superimposed and prevent the metal bipolar plate from being missed. The first interlocking structure 13 includes a lateral protrusion at the bottom of the housing unit, and a lateral groove is formed between the lateral protrusion and the bottom of the housing unit, and the second interlocking structure 14 includes a lateral protrusion at the top of the housing unit. Lateral protrusions, lateral grooves are formed between the lateral protrusions and the top of the housing unit, so that when the first connector and the second connector are inserted, the lateral protrusions of the first interlocking structure are inserted into the second In the lateral groove of the interlocking structure, at the same time, the lateral protrusion o...

Abstract

The invention relates to a stackable connector for fuel cell metal bipolar plate voltage detection, a metal bipolar plate is matched with a plurality of shell units stacked up and down, each shell unit is provided with a plurality of voltage acquisition units, one end of each shell unit is provided with a guide structure, and the other end of each shell unit is provided with a plurality of voltage acquisition units. The metal bipolar plate is provided with a guide groove matched with the guide structure, the shell units are inserted into the guide groove of the metal bipolar plate through the guide structure, a superposition self-locking structure is arranged between every two shell units which are stacked up and down, and spring type single-side locking structures are arranged on the outer sides of the shell units which are stacked up and down. Metal pole plate fins are arranged on the side faces of the metal bipolar plates, and anti-disengaging clamping jaws matched with the metal pole plate fins are arranged at the ends of the spring type single-side locking structures. According to the connector assembly, follow-up matching positioning connection is achieved through the stacking structure on the shell unit, the overall stability of the connector assembly is improved, and the possibility of missing detection of metal bipolar plates between the connector assemblies is avoided.

Description

technical field [0001] The invention relates to a superimposed connector for voltage detection of metal bipolar plates of fuel cells. Background technique [0002] In order to ensure the reliable operation of the fuel cell, it is necessary to monitor its voltage. Traditional connectors exist independently without any connection between them. The structure of this form is unstable, and it is easy to miss detection in the middle of the joints of the two connectors. [0003] After searching the literature of the prior art, it is found that there are few research reports on the metal bipolar plate voltage detection of the fuel cell that can be connected into an integral connector. Contents of the invention [0004] Due to the independent connection device, the overall structure is unstable, and missing detection is prone to occur between the connection devices. The purpose of the present invention is to provide a superimposed connector for voltage detection of fuel cell meta...
