Abstract

The utility model discloses an air tightness test machine for a wire harness waterproof jacket test. The air tightness test machine comprises an air storage tank, a water tank and an air inlet pipe, wherein the air storage tank is communicated with an air outlet pipe; a test jacket is arranged in the water tank; a wire on the test jacket is communicated with an air pipe; the air inlet pipe is communicated with an air pressure control valve; the air pressure control valve is connected with a pressure gauge; the air inlet pipe is also connected with a handle control switch; an air inlet of the air inlet pipe is communicated with the air outlet pipe; and an air outlet of the air inlet pipe is communicated with the air pipe. The air tightness test machine disclosed by the utility model has a reasonable structure design, is convenient to disassemble and mount, and can perform a precise air tightness test for the wire harness waterproof jacket to check whether leakage happens.

Description

The gas tightness testing machine of wire harness water proofing property sheath test usefulness
Technical field
The utility model relates to a kind of waterproof test device, mainly is a kind of gas tightness testing machine of wire harness water proofing property sheath test usefulness.
Background technology
Wire harness is installed on the automobile, has many plug-in units to be mounted in the position, wet district of automobile, and the sheath that is in position, wet district will be used the waterproof case of closed type.According to the relevant criterion requirement, waterproof case will be done air-tight test, for this reason, have corresponding gas tightness testing machine check on the automotive wire bundle plug-in unit with whether leakage phenomenon is arranged after the plug-in unit of car electrics end docks.When doing experiment usually; Be directly plug-in jacket to be communicated with escape pipe, check near the bubbling situation that the water tank plug-in part is, this method of operating does not have pneumatic control valve; Do not know the operational circumstances under great air pressure control, thereby can appear at underproof situation under certain air pressure after the inspection yet.
The utility model content
The utility model technical matters to be solved provides a kind of gas tightness testing machine of wire harness water proofing property sheath test usefulness; Its reasonable in design; Remove and install conveniently, can carry out accurate air-tight test to the wire harness water-proof jacket, whether check has leakage phenomenon.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of gas tightness testing machine of wire harness water proofing property sheath test usefulness includes gas-holder, is communicated with escape pipe on the gas-holder; Also include water tank, the test sheath is arranged in the water tank, the lead on the test sheath is communicated with tracheae; Also include draft tube; Be communicated with pneumatic control valve on the said draft tube, be connected with tensimeter on the pneumatic control valve, also be connected with the handle CS on the described draft tube; The air intake opening of described draft tube is communicated with escape pipe, and the gas outlet of draft tube is communicated with tracheae.
Said draft tube was communicated with connection-peg through tracheae with being communicated with all of escape pipe, tracheae.
The mode of operation of the utility model is:
1 get test usefulness to inserting sheath, with being coated in outside the sheath upper conductor after the hot melt adhesive heating that its sealing is air tight, wherein have a lead to be inserted in the tracheae, also will seal air tight on every side with hot melt adhesive.
2 when doing experiment, and the air intake opening of draft tube is communicated with escape pipe, and the gas outlet of draft tube is communicated with tracheae; Then sheath is put into water tank, at this moment, pull the handle CS, slowly pressurization; Each 0.02MPa stopped 30 seconds, and whether the nursing sheath edge reaches has bubble to produce; Be forced into 0.1MPa (1 atmospheric pressure) at last, stopped 30 seconds, if the sheath edge does not still have bubble; The proof water resistance is qualified, if be not pressurized to 0.1MPa bubble is not just arranged, and proves that water resistance is defective
The utility model has the advantages that:
The utility model reasonable in design removes and installs conveniently, can carry out accurate air-tight test to the wire harness water-proof jacket, and whether check has leakage phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Participate in Fig. 1, a kind of gas tightness testing machine of wire harness water proofing property sheath test usefulness includes gas-holder 1; Be communicated with escape pipe 2 on the gas-holder 1, also include water tank 3, test sheath 4 is arranged in the water tank 3; Lead on the test sheath 4 is communicated with tracheae 5, also includes draft tube 6, is communicated with pneumatic control valve 7 on the said draft tube 6; Be connected with tensimeter 8 on the pneumatic control valve 7, also be connected with handle CS 9 on the described draft tube 6; The air intake opening of described draft tube 6 is communicated with escape pipe 2, and the gas outlet of draft tube 6 is communicated with tracheae 5.
Said draft tube 6 was communicated with connection-peg 10 through tracheae with being communicated with all of escape pipe 2, tracheae 5.

Claims (2)

1. the gas tightness testing machine of a wire harness water proofing property sheath test usefulness includes gas-holder, is communicated with escape pipe on the gas-holder; Also include water tank, the test sheath is arranged in the water tank, the lead on the test sheath is communicated with tracheae; It is characterized in that: also include draft tube; Be communicated with pneumatic control valve on the said draft tube, be connected with tensimeter on the pneumatic control valve, also be connected with the handle CS on the described draft tube; The air intake opening of described draft tube is communicated with escape pipe, and the gas outlet of draft tube is communicated with tracheae.
