Description
Technical field
The utility model relates to hydrogen fuel cell field more particularly to a kind of hydrogen fuel battery metal bi-polar plate inspection leads
Plug structure.
Background technique
Check it is every economize on electricity heap voltage be implement battery control strategy basis, the prior art usually by the lead of inspection with
Bipolar plates are by welding or are inserted into realization connection in the hole that bipolar plates are arranged.Patent No. 201510643039.X and the patent No.
CN102945967 discloses the jack connection structure of bipolar plates inspection line, patent No. ZL201210436284.X pile inspection line
Jack connection structure, but due to metal double polar plates very thin thickness so that the distance very little between each metal double polar plates, that
The spot size of welding position is improper or welding particle is fallen will cause between bipolar plates short-circuit, and soldering appliance is also difficult to
Into；And for the connection structure of jack type, since sheet metal is easy to deformation, lead is easy to loosen or fall off to cause
The state of virtual connection influences the measurement of voltage.Therefore a kind of connection type for linking stability and high efficiency is found, it is necessary to.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides a kind of hydrogen fuel battery metal bi-polar plate inspection lead
Plug structure.
The utility model is to reach technical solution used by above-mentioned technical purpose to be: a kind of hydrogen fuel battery metal bi-polar
The plug structure of plate inspection lead, which is characterized in that the plug structure includes: the first branch, the second branch and third branch,
First branch and the second branch are in fork configuration, and the third branch is parallel with the first branch.
In some embodiments, first branch length is 2-4mm, aperture 0.6-1.2mm.
In some embodiments, second branch length is 2-4mm, aperture 0.6-1.2mm.
In some embodiments, the third branch length is 1-2mm, aperture 0.6-1.2mm.
The beneficial effects of the utility model are: using the above structure, it is firm to connect between inspection line and bipolar plates；Inspection line
Contact resistance between bipolar plates is small；Convenient for automation, integration production: metal double polar plates are will be negative with laser welding mode
What pole veneer and anode veneer were welded, inspection lead and bipolar plates are linked together using identical technology and equipment,
Be conducive to the automation and integration production of bipolar plates；It is convenient for safeguarding, in the case where inspection line loosens, it is not required to dismantle pile,
Can be in the spliced eye of branch type side, online addition conducting resinl bonds inspection line and bipolar plates.
Detailed description of the invention
Fig. 1 is y-type structure schematic diagram.
Fig. 2 is welding schematic diagram.
Specific embodiment
For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation
Mode simultaneously cooperates attached drawing to be explained in detail.
It please refers to shown in Fig. 1, Fig. 2, the utility model provides a kind of connecing for hydrogen fuel battery metal bi-polar plate inspection lead
Inserting structure, as shown in Figure 1a, the length of side branch 2 is 2-4mm, aperture 0.6-1.2mm to y-type structure 1, other side branch
4 length is 2-4mm, aperture 0.6-1.2mm, and the angle of branch 2 and branch 3 is 20-80 °, and branch 3 is parallel with branch 2, is grown
Degree is 1-2mm, aperture 0.6-1.2mm.
Axial, cross-sectional view along branch 2 is as shown in Figure 1 b, is made of the semicircle 7 of semicircle 6 and cathode plate on anode plate, sun
Pole plate semicircle 6 and cathode plate semicircle 7, stamped molding, material is 316 stainless steels, with a thickness of 0.08-0.3mm, preferably 0.1mm.
When welding, y-branch 2 is inserted at nuditing wire end 8, until 3 bottom of branch.Using laser welding technology by inspection
Wire bonding in Y type connection-peg, welding position two shown in 10 at position, this at two position should crunode 9 along branch 2 with
Upper bit.Weld optical maser wavelength 1064nm, power 500w
Inspection loosens, and when needing to safeguard, from the other side of breeches joint 4, injects conducting resinl, conducting resinl enters through branch 4 and divides
Branch 3, so that conducting wire is fixed in Y type connection-peg.
Effect: it is firm to connect between inspection line and bipolar plates；Contact resistance between inspection line and bipolar plates is small；Convenient for dimension
Shield；Metal double polar plates are that cathode veneer and anode veneer are welded with laser welding mode, use identical welding skill
Art and device link together inspection lead and bipolar plates, are conducive to the batch automatic production of bipolar plates.
In conclusion the present embodiment is using the above structure, it is firm to connect between inspection line and bipolar plates；Inspection line with it is bipolar
Contact resistance between plate is small；Convenient for automation, integration production: metal double polar plates are to use laser welding mode by cathode veneer
It is welded with anode veneer, inspection lead and bipolar plates is linked together using identical technology and equipment, are conducive to
The automation and integration production of bipolar plates；It is convenient for safeguarding, it in the case where inspection line loosens, is not required to dismantle pile, can divide
In the spliced eye of forked type side, online addition conducting resinl bonds inspection line and bipolar plates.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
