Connector with insertion total number detection function

Abstract

The invention relates to a connector with a plug total number detection function, which comprises a socket and a plug, and is characterized in that the socket comprises a socket shell, a socket detection contact element and a socket printed board component, and a first coaxial jack plugged with the rear end of the socket detection contact element is welded on the socket printed board component; the plug comprises a plug shell, a plug detection contact element and a plug printed board part; a second coaxial jack which is plugged with the rear end of the plug detection contact element is welded on the plug printed board part; a first signal collection circuit and a first MCU are integrated on the socket printed board component, and a second signal collection circuit and a second MCU are integrated on the plug printed board; when the plug and the socket are plugged, the socket detection contact element and the plug detection contact element are in contact conduction, the first signal collection circuit and the second signal collection circuit can detect contact conduction signals and transmit the contact conduction signals to the corresponding MCUs, and the MCUs respectively process the contact conduction signals, so that the functions of independent plug total number and plug in-place detection of the plug and the socket are realized.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a connector with a mating count detection function. Background technique [0002] At present, connectors are mainly used in electronic systems in automotive, industrial, medical, aerospace, weaponry and other fields, mainly to realize electrical connection and signal energy transmission. When it is used as the main interface of the energy source, due to the long-term transmission of high power, it is easy to burn the contact part between the pin and the socket contact, which will cause the equipment to fail to work. Then cause the whole system to be paralyzed, and then lead to major safety accidents. For example, the power connector is the energy inlet in the spacecraft cabin. Once a failure occurs (contacts broken, aged, shorted), it will cause serious failures such as functional failure of the spacecraft. Therefore, other measures need to be taken to improve the reliabilit...

Problems solved by technology

[0004] At present, the number of plugging and unplugging of the connector is counted by external equipment such as a mechanical life tester. When using this test method, the connector is in a non-working state. We can only use it to count the mechanical life threshold of the connector, not Real-time monitoring of the working status of the connector and does not have the prompt function of mating in place
