The invention relates to a connector for online current detection and its active end, which belongs to the field of connector performance measurement. The connector includes an active end and a passive end. The active end has a built-in circuit board, and the circuit board has a current detection circuit , the current detection circuit has a current signal input terminal, and the active terminal has a built-in current sensor for detecting the current flowing through the signal contact piece of the active terminal. The current sensor is connected to the current signal input terminal. superior. The present invention detects the current of the signal contact piece of the active end through the magnetic collecting sheet sensor, and sends the current to the current signal input end of the current detection circuit, so as to realize the online detection of the working current of the connector, and through the integrated circuit board of the active end The integration of the current detection device inside the connector is realized with the magnetic collecting sheet sensor, and the volume of the integrated active end and the connector is relatively small, and no change is required to the external structure size of the existing plug and socket.
Description
Technical field [0001] The present invention belongs to the field of connector performance measurement, specifically relates to a current online detection of the connector and its active end. Background [0002] At present, the internal state of the traditional passive connector is unknown relative to the external system, and it cannot be effectively monitored, and the connector as a system signal interconnection interface, once it fails, it will cause catastrophic consequences to the entire external system, such as the high-current connector usually used in the key equipment of the generator, mine and other system, as the main interface of the energy source, once it suddenly fails, it causes equipment downtime, and the heavy causes the entire system to be paralyzed, which in turn causes major safety accidents. In order to achieve failure prediction and health management at the system-wide level, it is necessary to first visualize the internal state of the connector and monitor ...
