Problems solved by technology

[0004] At present, the air tightness detection equipment of wire harness connectors is to fill the wire harness connectors with stable pressure gas for a period of time, and the gas leakage or pressure drop value is used as the judgment condition, which requires high precision equipment and requires power and gas sources around; For the mass-produced wire harness connectors, this detection method is difficult to detect in a large range; and this test method needs to completely seal the test wire harness connectors, there must be no unsealed joints, and it is impossible to detect wire harnesses with too many ports

Abstract

The invention provides novel portable wire harness connector sealing performance testing equipment. The novel portable wire harness connector sealing performance testing equipment comprises a shell unit, a testing unit installed in a handheld shell and a control unit used for being connected with the testing unit. The testing unit comprises an air source module used for inflating a wire harness connector to be tested, and a spraying module used for carrying out auxiliary observation on the inflated wire harness connector to be tested. The device is reasonable in overall structural design, and the airtightness of the wire harness connector can be tested. The access of an external power supply and an external air source is not needed in actual use, and the device is not limited in actual use. The device is simple in overall structural design and low in manufacturing cost; and the device is convenient to carry and has higher practicability in actual use.

Description

technical field [0001] The invention relates to the technical field of airtightness testing equipment for wire harness connectors, in particular to a new type of portable wire harness connector airtightness testing equipment. Background technique [0002] As we all know, in order to ensure the safety of use, most wire connectors must be tested for airtightness. [0003] As an important part of the wiring harness connection, the wire harness connector is relatively high in use nowadays. The precision and durability of the wire harness connector products make it capable of meeting high standards because of the stability and safety of the wire harness connector It will affect the actual safety of the product, so the air tightness detection of the harness connector is very important, which is also one of the important indicators to ensure the safety of consumers. [0004] At present, the air tightness detection equipment of wire harness connectors is to fill the wire harness co...
