Description

Technical Field

[0001] The utility model belongs to the technical field of connector detection, and in particular relates to a miniaturized waterproof connector airtightness testing device for simulating high temperature environment. Background Art

[0002] A connector is a device that connects two active devices. It is mainly used to transmit current or signals. It is an indispensable component of electronic equipment. During the production and processing of connectors, it is usually necessary to undergo various tests such as electrical conductivity, high temperature testing, and air tightness testing.

[0003] At present, when a connector is subjected to a high-temperature test, the connector is usually placed in an environmental chamber for high-temperature aging. When the aging time is reached, the connector is tested for air tightness. As a result, when this method is used for high-temperature testing, the air tightness of the connector can only be tested after the high temperature ends and the connector has been left at room temperature for a period of time. Although this method can detect whether the connector seal can be restored to the initial sealing state after aging, it cannot detect the airtight performance of the connector in a high-temperature environment, and cannot guarantee the stability of the connector in a long-term operation in a high-temperature environment.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a miniaturized waterproof connector airtight performance test device for simulating high temperature environment.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0028] AsFigures 1 to 3 As shown, a conveying air hole 4 is drilled on the side of the detection bottom block 1 facing away from the assembly through hole 3. Both the assembly through hole 3 and the conveying air hole 4 are in communication with the detection cavity 2. Gas is conveyed into the detection cavity 2 through the conveying air hole 4, facilitating the airtightness detection of the connector 7.

[0029] As Figures 2 to 3 shown, an air pipe joint 8 is inserted into the conveying air hole 4. Gas required for airtightness detection is conveyed into the conveying air hole 4 through the air pipe joint 8, providing a basis for the subsequent airtightness detection of the connector 7.

[0030] As Figures 2 to 3 shown, one end of the air pipe joint 8 located outside the conveying air hole 4 is inserted with a conveying air pipe 9. The airtightness of the connector 7 is detected by connecting the conveying air pipe 9 to an airtightness machine externally.

[0031] As Figures 1 to 2 shown, a sealing top cover 5 is fixedly assembled above the detection bottom block 1. The detection cavity 2 is enclosed and limited by the sealing top cover 5.
