When the working state information of the electrical module 20 is out of the set safety range When within the safe range, the plug terminal 24 is automatically disconnected from the electrical connection with the plug socket 122, so that the electrical module 20 is powered off and slides forward in an unsafe working state, so that the electrical module 20 can be released from the dangerous work in time. In this state, the electrical module 20 is prevented from being damaged; and the design structure of the pull-out unit 60 is simple and practical, and the electrical module 20 can be driven to slide forward by pressing the rotating member 62 against the front surface of the cabinet 10 during the rotation process, so that the electrical module 20 and the The plugging and unplugging operation of the plug socket 122 is more rapid, which further shortens the time when the connector and the electrical module 20 are in a dangerous working state.

Correspondingly, the present invention also provides a method for controlling the safety of a connector. The method is used in the safety protection device in the above embodiment, and includes the following steps:

Collect the current working state information of the electrical module 20 and/or the connector, that is, the temperature sensor 31 detects the temperature value inside the plug terminal 24, and the pressure sensor 32 detects the pressure value between the electrical module 20 and the plug socket 12;

Judging whether the current working status information of the electrical module 20 and/or the connector is out of the set safety range, if the judgment result is yes, output the exit instruction, that is, the processor 50 receives the temperature value sent by the temperature sensor 31 and the pressure sensor 32. the pressure value, compare the temperature value and the first threshold value, and the pressure value and the second threshold value, if the temperature value exceeds the first threshold value or the pressure value exceeds the second threshold value, then the electrical module 20 is powered off first, Then output the exit command;

After the driving member 61 receives the withdrawal instruction, the rotating member 62 is driven to rotate to abut against the front surface of the cabinet 10, so that the electrical module 20 slides forward to be partially separated from the installation channel 11, and the plug terminal 24 is disconnected from the plug socket 122. After the drive motor 61 receives the exit instruction, it makes the first rotating gear 611 rotate counterclockwise, the second rotating gear 612 rotates clockwise, the rotating member 62 rotates counterclockwise, and the rotating part 621 gradually extends out of the opening at the lower right top corner of the front plate 22 , and pushes against the right side of the front surface of the cabinet 10, that is, pushes against the right column 13, and drives the electrical module 20 to slide forward gradually, so that the electrical module 20 slides from the first position to the second position, so that the electrical module 20 is in the In an unsafe working state, the power is cut off and it slides forward to avoid damage to the electrical module 20 .

In this method, when the working state information of the electrical module 20 and/or the connector is within the set safety range, the electrical module 20 is located in the installation channel 11, and the plug terminal 24 is electrically connected to the socket 12. When the electrical module 20 and When the working state information of the connector is out of the set safety range, that is, the electrical module 20 is driven to slide forward, so that the plug terminal 24 is automatically disconnected from the electrical connection with the socket 12, so that the electrical module 20 and/or the connection The device is powered off and slides forward in an unsafe working state, so that the electrical module 20 and the connector can be released from the dangerous working state in time, and the electrical module 20 and the connector are prevented from being damaged; and the design of the pull-out unit 60 is simple. Practical, making the plug-in operation of the electrical module 20 and the socket 12 more rapid, and further shortening the time when the electrical module 20 is in a dangerous working state.
