Embodiment 1

[0049] see figure 2 , an integrated quick-plug device for fuel cell metal bipolar plate voltage detection, including a plastic shell and a metal reed 3. The plastic casing includes a first plastic casing 1 and a second plastic casing 2, and both the first plastic casing 1 and the second plastic casing 2 can be made of polymer, resin or other insulating materials.

[0050] The first plastic shell 1 and the second plastic shell 2 are a butt joint structure. see figure 2 and image 3 , the connecting surface of the first plastic shell 1 is provided with buckle 4 and guide post groove 5, and the second plastic shell 2 is provided with bayonet 6 matching with buckle 4, and the second plastic shell 2 A guide post 7 matching with the guide post groove 5 is provided on the connection surface. In this embodiment, the number of the buckle 4 and the bayonet socket 6 are two, and the number of the guide post groove 5 and the guide post 7 is six.

[0051] see figure 2 and Figure...

Embodiment 2

[0057] see Figure 6 , an integrated quick-plug device for fuel cell metal bipolar plate voltage detection, including a plastic shell 20 and a metal reed 3 . The plastic shell 20 is provided with reed insertion slots, fin interfaces, fin slots, wire interfaces 12, guide posts 13, and cantilever buckles 14, and the structure of this part is the same as that in Embodiment 1.

[0058] The difference from Embodiment 1 is that the plastic shell 20 is integrally injection-molded, and the metal reed 3 is inserted into the reed inserting groove 8 from the wire interface 12 at the tail end of the plastic shell 20 . The integrated quick plug-in device also includes a stop block 22, the rear end of the plastic shell 20 is provided with a stop block installation groove 21, the stop block installation groove 21 is arranged crosswise with the wire interface 12, the stop block installation groove A stop block 22 is installed in the 21, protrusions 23 are provided on both sides of the stop b...

Abstract

The invention discloses an integrated quick-plug device for voltage detection of a metal bipolar plate of a fuel cell, which comprises a plastic shell and a metal reed, wherein a reed imbedding grooveis formed in the plastic shell, a fin connector and a fin inserting groove are formed in the front end, a wire connector is formed in the tail end, and the fin connector and the wire connector are both communicated with the reed imbedding groove; the metal reed is installed in the reed imbedding groove, the front end is in a clamping piece shape, the tail end is in a U shape, and a metal reed pressing structure is arranged on the plastic shell; and the two sides of the plastic shell are connected with a guide column and a cantilever buckle respectively. A plurality of detection units are integrated into one quick plug device to realize integrated detection; the plastic shell can be manufactured separately or integrally; the metal reed pressing structure not only has a pressing effect on the metal reed, but also has a pressing effect on an accessed wire; guiding is achieved when the guiding column and the metal bipolar plate are assembled, locking is achieved when the cantilever buckleand the metal bipolar plate are assembled, and reliable connection between the integrated quick-plug device and the metal bipolar plate is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fuel cells and relates to a test device for fuel cells, in particular to an integrated fast plug-in device for voltage detection of metal bipolar plates of fuel cells. Background technique [0002] In order to ensure the reliability of fuel cell work, it is necessary to monitor its voltage. see figure 1 , the traditional method is to crimp the wire to the metal pin, and then insert the metal pin into the metal bipolar plate. This connection method is difficult to operate on a large stack, and there may be faults such as crooked deformation of the pin insertion and failure of the vibration connection. Contents of the invention [0003] In view of the above problems, the present invention provides an integrated quick-plug device for voltage detection of metal bipolar plates of fuel cells. [0004] The purpose of the present invention can be achieved through the following technical solutions: an integra...
