Background

With the progress of science and technology, environmental protection requirements are more and more emphasized. The automobile on the market at present develops from the fuel gradually to clean energy, more and more people begin to use new energy automobile, and the air conditioning system of new energy automobile uses electric scroll compressor, because the drive system of compressor mostly uses high voltage, require that the security performance of electrified part reaches national standard waterproof requirement, consequently need detect the leakproofness of electric cavity, because be the finished product when detecting, spare part is sealed installation, consequently, need place its whole in the aquatic below 1 meter when detecting, because can't see whether sealed under 1 meter of water, consequently, after long-time the putting, need take out to take out and just can discover inside infiltration after taking apart, whether sealed suitable. If the interior has water, the leakproofness of electrified cavity is unqualified, if the interior does not have water after taking out after submerging for a period of time, the leakproofness is better. However, the method for detecting under 1 m water requires large occupied area of equipment, long detection time and disassembly and inspection, and is not suitable for flow line production. In fact, the pressure in the outside environment can be obtained through simulation, for example, injecting gas with equal pressure into the cavity is a feasible method, but how to inject gas with pressure into the cavity is a problem to be solved.

The to-be-solved technical problem of the utility model is: the problem of how to pour into pressure gas and detect in the cavity is solved.

In order to solve the technical problem, the technical scheme of the utility model provides an electric cavity's sealed structure that detects is provided, including the cable, the cable comprises insulating layer and copper line tied in a bundle, is equipped with the clearance between insulating layer and the copper line tied in a bundle, and in the electric cavity that forms between insulating layer and the copper line tied in a bundle stretched into by the motor cover and the casing, the outer wall and the electric cavity sealing connection of cable, in the other end of cable inserts the connector, the outer wall of cable passes through the one end sealing connection of sealing plug and connector, a serial communication port, the other end of connector and the one end sealing connection to the plug-in, to the other end and the tracheal one end sealing connection of plug-in, the one end of relief pressure valve is connected to the tracheal other end, inflatable structure is connected to.

Preferably, a terminal is fixed in the connector, and one end of the terminal is riveted with the head of the bundled copper wire; the plug-in components are sleeved outside the terminals.

Preferably, the terminal is fixed on one end of the bracket, the other end of the bracket is fixed on the inner wall of one end of the connector, and one end of the bracket is also provided with a small hole through which gas coming out of the gas supply pipe can pass.

Preferably, the outer wall of the counter insert is sealingly connected to the inner wall of the connector by a sealing ring.

Preferably, the other end of the plug-in unit is fixedly connected with the outer wall of the trachea through a sealant in a sealing manner.

Preferably, the inflation structure is a gas tank or a pressure pump.

The utility model discloses in stretching into the electric appliance cover with the one end of cable, the other end passes through the connector and links the breather pipe to the plug-in components for pressure gas that comes out in the trachea injects into the electric appliance cover through the clearance between the copper space tied in a bundle of cable, makes pressure in the electric appliance cover the same with the water pressure of the aquatic below 1 meter according to the gas of injecting into, and the method of reuse helium leak hunting or water detection detects. The utility model has the advantages of simple structure, convenient to use, through the utility model discloses can be quick detect the leakproofness of electric cavity, improve detection efficiency, and need not to disassemble and look over.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to an electric cavity's sealed structure that detects, as shown in FIG. 1, form an electric cavity through each sealed structure between electrical apparatus cover 3 and casing 1, driver 2 installs in electric cavity, in cable 4's one end stretched into electric cavity, through sealing plug sealing connection between cable 4's outer wall and the electric cavity, cable 4 that draws from electric cavity comprises insulating layer 4a and copper wire bundling 4b, all be equipped with the clearance between insulating layer 4a and copper wire bundling 4b and between copper wire bundling 4 b. In cable 4's the other end inserts connector 5, cable 4 passes through inside that sealing plug 6 got into connector 5, cable 4's outer wall passes through sealing plug 6 and connector 5's one end sealing connection, connector 5 internal fixation has terminal 11, copper line 4 b's head tied in a bundle rivets with the one end of terminal 11, there is sealing ring 7 in the connector body 5, the inner wall sealing connection of the outer wall of 8 one ends of plug-in components through sealing ring 7 and the 5 other ends of connector, install trachea 10 through sealed glue 9 on plug-in components 8, the sealed fixed connection of outer wall through sealed glue 9 and trachea 10 to plug-in components 8's the other end promptly. The other end of the air pipe 10 is connected with one end of a pressure reducing valve 12, and the other end of the pressure reducing valve 12 is connected with an inflating structure 13.
