Description
Technical field
The present invention relates to fuel cell fields, specifically, more particularly to a kind of fuel battery double plates and fuel cell
Voltage polling plug-in unit.
Background technique
Fuel cell is a kind of clean energy technology that chemical energy is directly translated into electric energy, has high-energy conversion effect
The advantages that rate, structure be simple, low emission, low noise, is usually used in the dynamical system of the delivery vehicles such as vehicle, ship, and may be used as moving
Dynamic formula or fixed power station.Multi-disc bipolar plates and membrane electrode are usually passed through positioning tool piecewise by fuel cell pile
Stack and fasten, cell voltage cruising inspection system is a kind of for monitoring the device of cell health state, is adopted comprising voltage
Storage, inspection harness, the inspection connecting pin in bipolar plates, when fuel cell failure problem, by voltage collector
Signal, can accurate judgement which batteries go wrong, to take counter-measure in time, avoid battery performance sharply
Deteriorate；The premise for guaranteeing pile safe and reliable operation to the accurate measurements of each unit voltage, thus voltage polling system and
Being reliably connected for each single battery plays very crucial effect.
In the prior art, often by inspection harness and fuel battery double plates by welding, link together into
Row voltage signal acquisition is easy to appear welding mistake in the welding process, if fruit mis-welds are primary, entire welding process is just
It does again from the beginning, efficiency is extremely low in this way for institute, is not able to satisfy production requirement completely, and be easy to happen the feelings that solder joint falls off
Condition needs the inspection line of welding to dismantle, process is very complicated in pile maintenance process.
Such as a kind of metal double-polar-plate fuel cell galvanic inspection line connection method (Publication No. of patent
CN102938470A, publication date 2013.02.20), according to the distance of metal polar plate inspection jack, press out and inspection jack
Compatible bus bar connector, then winding displacement needle inserting device is inserted into inspection jack, while the other end of bus bar connector and electricity
The connection of pond cruising inspection system.The method can avoid welding manner and connect bring unstability, improve inspection reliability.But this sends out
The plug method of bright use, be easy to cause position inaccurate, while in swapping process, and plug position tightness is not allowed easily-controllable
System, inspection harness easily fall off.
(Publication No. CN109449462A, publication date are a kind of self-assembled structures of fuel battery voltage inspection of patent
2019.03.08), by turn screw rod drive threading action part moved in shell so that two clamp clips it is close to each other to
The fin on pole plate is clamped, due to the limitation of bipolar plate thickness, and battery is large number of, and generally several hundred stackings need
A piece screw rod drives several hundred a threading action parts, the equal very little of size and stroke of threading action part, and precision is not easy to guarantee, it is difficult to fill
Match, the deviation of stroke of threading action part is larger, it is difficult to guarantee the homogeneity clamped；If screw rod is made of metal material, a side
Face can have huge short-circuit risks, and conducting wire will avoid screw rod and threading action part, and the connection with clamp clip is not easy to realize；
On the other hand, since the thickness of bipolar plates limits, threading action part and clamp clip are very thin, and rigidity is smaller, it is difficult to guarantee that each section is equal
Even clamping, and manufacture is highly difficult, is not easy to realize；It is made according to nonmetallic materials, since screw rod length is longer, screw thread rigidity
Deficiency is transmitted to the insufficient clamping force on clamp clip by screw thread, exists and the insecure risk of the connection of bipolar plates fin.
