Abstract

The utility model provides an air tightness detecting system of a wire harness connector, which comprises an air tightness test module, wherein an accommodating chamber hermetically connected with the wire harness connector is arranged inside the air tightness test module; an input air pipe and an output air pipe are connected to the accommodating chamber; the input air pipe is connected with an air source through a magnetic valve switch; the output air pipe is connected with a pressure sensor; and the magnetic valve switch and the pressure sensor are respectively and electrically connected with a tester through signal wires. The system can realize quick and efficient air tightness detection of wire harness sealing elements, and prevent water leakage and seepage.

Description

The airtight detection system of Wiring harness connector
Technical field
The utility model relates to the airtight detection system of a kind of Wiring harness connector.
Background technology
Wire harness is the line electricity subassembly that connects each electric equipment in the circuit, form by connector, connection terminal, lead and the wrapper material of becoming attached to etc., for the conducting letter that can detect each circuit can, guarantee that electrical equipment can operate as normal, check by electrical property and test.At present the test of electric conductivity has just been carried out in the detection of each circuit and fixture in the wire harness, its shortcoming is, sealing as some rubber parts in the Wiring harness connector and seal is to detect, and partial function was lost efficacy.
The utility model content
The technical problems to be solved in the utility model provides a kind of to the airtight detection system of Wiring harness connector, and it can make things convenient for, realize efficiently the airtight detection of Wiring harness connector.
The airtight detection system of the Wiring harness connector that the utility model provides, comprise airtight test module, be provided with a cavity volume that is tightly connected with Wiring harness connector in the described airtight test module, be connected with gas inlet tube and gas outlet tube on the described cavity volume, described gas inlet tube is connected with source of the gas by electromagnetic valve switch, described gas outlet tube is connected with pressure transducer, and described electromagnetic valve switch, pressure transducer are electrically connected with test machine by signal wire respectively.
Preferably, described test machine is connected with printing equipment, when test is passed through, prints qualified label.
Preferably, described airtight test module takes the shape of the letter U.
The airtight detection system of Wiring harness connector of the present utility model can realize rapidly and efficiently that the impermeability of wire harness seal detects, and prevents to leak and seep water.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the airtight detection system of Wiring harness connector of the present utility model, comprise the airtight test module 1 of U-shaped, be provided with a cavity volume 10 that is tightly connected with Wiring harness connector 8 in the airtight test module 1, be connected with gas inlet tube 5 and gas outlet tube 6 on the cavity volume 10, gas inlet tube 5 is connected with source of the gas 9 by electromagnetic valve switch 2, gas outlet tube 6 is connected with pressure transducer 3, electromagnetic valve switch 2, pressure transducer 3 are electrically connected with test machine 4 by signal wire 7 respectively, test machine 4 is connected with printing equipment, when test is passed through, promptly print qualified label.
During use, Wiring harness connector to be detected 8 is inserted the cavity volume 10 of airtight test module 1, this moment, cavity volume 10 was sealed by Wiring harness connector 8 gentle density test modules 1, start test machine 4 then, test machine 4 sends a signal and gives electromagnetic valve switch 2, electromagnetic valve switch 2 is opened, source of the gas 9 carries the gas of certain air pressure to enter airtight cavity volume 10 by gas inlet tube 5, export by gas outlet tube 6 from airtight cavity volume 10 again, if connector 8 is airtight good, then the pressure transducer 3 that links to each other with cavity volume 10 will measure an air pressure the same with admission pressure, and this moment, pressure transducer 3 can send a signal to test machine, and test machine is by airtight test and print qualified label.If Wiring harness connector 8 is airtight bad, airtight cavity volume 10 will constantly leak gas, and can't maintain admission pressure, and the air pressure that this moment, pressure transducer 3 measured will be less than admission pressure, pressure transducer 3 just can't send signal and give test machine, and test machine just can't be by not printing qualified label.When test finishes, close test machine, take out Wiring harness connector 8 then.
The airtight detection system that the utility model adopts is used for automobile, aviation, and the wire harnesses production field has guaranteed the air-tightness of each seal, has prevented the phenomenon of leaking and seeping water, and can be used for the wire harness mass production fast and efficiently.
More than just utility model has been carried out exemplary explanation, specific implementation of the present utility model is not limited thereto.The insubstantial modifications that any employing design of the present utility model and technical scheme are carried out is all within protection domain of the present utility model.
