Problems solved by technology
For example, in the application of a normally open limit switch, the limit switch is usually connected to the interface of the control chip through a plug. If the limit switch is not triggered, the control chip cannot judge whether the limit switch is valid, and if the plug is loose, then The control chip does not know that the limit switch is triggered, which may cause serious consequences

The embodiment of the invention provides a detection device for detecting the connection state of a connector, and the device comprises a socket, the socket comprises a detection signal transmitting port and a detection signal receiving port, and the detection signal transmitting port is configured to access a detection signal and transmit the detection signal to the detection signal receiving port under the condition that a plug is inserted into the socket; and a processor configured to receive the detection signal from the detection signal receiving port, and determine that the plug is correctly inserted into the socket. According to the technical scheme, as long as the detection signal receiving port of the socket of the detection device between the processor and the controlled element can receive the detection signal, it is proved that the plug and the socket are well plugged, otherwise, it is considered that the plug is tripped, and the detection device detects whether the elements in the electrical appliance have poor contact or not, therefore, the occurrence of accidents is reduced, the reliability of products is improved, the difficulty in monitoring and maintenance is reduced, time and labor waste of operators is avoided, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of circuit detection, in particular to a detection device and an electrical appliance for detecting the connection state of a connector. Background technique [0002] Most electrical equipment contains a control chip. The user operates through an interactive interface, sends a control signal through the control chip, and the controlled component starts to operate after receiving the control command. Usually, the control chip is equipped with an interface corresponding to the controlled component, and the controlled component is connected to the interface through a plug to realize signal connection, such as PLC controls the motor, and stm32 controls the LED on and off. But for some circuits, the effect that the plug has been inserted into the interface is the same as that the plug has not been inserted into the interface, and only the device on the plug will respond in a special environment. For example, in ...
