Description
Technical field
The utility model relates to a kind of connectors of connection, and in particular to a kind of dedicated for battery pack air-leakage test use
Connector, for being connected with the explosion-proof valve in battery pack.
Background technique
New energy resource power battery packet is new-energy automobile " heart ", core of the power battery as new-energy automobile
Part, safety and the operation is stable, reliability directly ring the service performance and safety for arriving new energy electric motor vehicle.In order to pre- anti-electric
Interior battery is wrapped in pond to be influenced by water, dust etc., and battery pack cabinet requires to be sealed, and waterproof and dust-proof degree of protection are wanted
Seek the GB4208-2008 that is up to state standards " shell protection grade " (IP code) IP67 or more.
Detection for seal case degree of protection is protected in GB4208-2008 standard clear stipulaties IP67 or more
The test method and requirement of grade: dust-proof test is tested using talcum powder in dustproof test box, it is desirable that in off-test cabinet not
There can be dust deposit；Waterproof test requirement 1 meter of depth of water of immersion, the testing time at least 30 minutes.It is detected by the above standard method, behaviour
Make complexity, the used time is more, and detection rear box is stained with water and dust, needs to clean, is dry, and detection post-processes trouble, is adapted only to
The requirement quickly detected in battery pack batch production processing procedure is not achieved in sampling inspection, is that the industry is interior in batch production processing procedure
Using inflate or vacuumize and pressure maintaining for a period of time, then seeing whether gas leakage, whether good seal is verified to verify cabinet
Cabinet protection effect.
In order to inflate or vacuumize into battery pack cabinet, following methods are generally used at present:
(1) threaded hole is bored on cabinet, is connect gas-charging connection and is detected, although the method inflation detection speed is fast,
But on cabinet need to open a hole more, cabinet difficulty of processing is increased, and install one again after qualification after inflation detection
Bolt carries out secondary plugging sealing, operates cumbersome.
(2)) explosion-proof valve in battery pack is covered using a fixture.The structure of typical explosion-proof valve is as shown in Fig. 2, have
The clamping ring 114 connected for the interface with battery pack, the spool 111 being arranged in clamping ring 114, set on clamping ring 114
It is equipped with card slot 112, spool 111 is fastened on clamping ring 114 by elastomeric elements such as springs, after spool 111 lifts,
Gap 113 is formed between the cover and clamping ring of spool.Waterproof, ventilated membrane are additionally provided in spool.Fixture covers battery
The explosion-proof valve wrapped, be by explosion-proof valve inside ventilated membrane cabinet in inflate or vacuumize and detected, but waterproof is saturating
Air film Air permenbility is typically small, and aeration speed is very slow, and detection efficiency is low, is directed to the airtight detector test resultant error of pressure differential method
It is big, or even because Air permenbility too it is small can not when row detection judgement, and if making waterproof ventilated membrane with existing if high-pressure aerated
Breakage leads to the risk of explosion-proof defective valve.
Obviously, above operation have the shortcomings that risk below or:
(1) aeration aperture is opened up on cabinet, is needed one bolt of installation after there is inflation detection examination, is carried out secondary seal,
It is complicated for operation and bad there are secondary seal and cannot or be difficult to reach the risk of protection level requirements.
(2) it inflates or is evacuated in cabinet by the ventilated membrane of explosion-proof valve, inflation or the speed of evacuation are very slow, there is detection
The problem of low efficiency, and ventilated membrane Air permenbility is less, and larger with the airtight detector test error of pressure difference, there are larger erroneous judgements
Risk, or even cannot accurately detect and determine battery pack leakproofness.
(3) it inflates or vacuumizes from ventilated membrane, if misoperation, existing keeps waterproof ventilated membrane damaged, leads to explosion-proof valve
The risk of water-proof function failure.
