The control module 130 is configured to control the moving module 110 to reciprocate along the plugging and unplugging directions of the target interface a and the mating interface B, so as to control the automatic plugging and unplugging of the target interface a and the mating interface B.
The motion module 110 is a device that is fixedly connected to the target interface a to drive the target interface a to move. The fixing clamp 120 is a device that is fixedly connected with the mating interface B for testing, so that the mating interface B is plugged into or pulled out of the target interface a in a process that the moving module 110 drives the target interface a to move.

When the control signal is a first digital signal, the main control unit 131 supplies power to the motion module 110 to control the motion module 110 to drive the target interface a to be pulled out of or inserted into the mating interface B. When the control signal is the second digital signal, the main control unit 131 stops supplying power to the motion module 110 to control the motion module 110 to drive the target interface a to be inserted into or pulled out of the mating interface B.
Illustratively, the first digital signal may be a "1" and the second digital signal may be a "0". It should be noted that, when the main control unit 131 supplies power to the motion module 110 and controls the motion module 110 to drive the target interface a to be pulled out from the mating interface B, the main control unit 131 drives the target interface a to be inserted into the mating interface B when the main control unit 131 stops supplying power to the motion module 110; when the main control unit 131 supplies power to the motion module 110, the motion module 110 is controlled to drive the target interface a to be inserted into the mating interface B, and when the main control unit 131 stops supplying power to the motion module 110, the main control unit 131 drives the target interface a to be pulled out from the mating interface B.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a motion module 110 according to an embodiment. As shown in FIG. 2, one embodiment of the motion module 110 includes a servo 111 and a solenoid 112. The target interface a is mounted on the servo 111, and the servo 111 is configured to reciprocate along the plugging direction. The electromagnetic coil 112 wraps the servo mechanism 111, the electromagnetic coil 112 is electrically connected with the output end of the main control unit 131, and the electromagnetic coil 112 is configured to drive the servo mechanism 111 to drive the target interface a to move to a target position when the main control unit 131 supplies power, and drive the servo mechanism 111 to drive the target interface a to reset to a preset position when the main control unit 131 stops supplying power.
In the present embodiment, the servo 111 may be an iron core. Because the electromagnetic coil 112 is electrically connected with the main control unit 131, when the main control unit 131 supplies power, the electromagnetic coil 112 and the servo mechanism 111 form a magnetic body, and a magnetizer is fixedly arranged at a target position, so that the electromagnetic coil 112 can drive the servo mechanism 111 to drive the target interface a to move to the target position when the main control unit 131 supplies power, and when the main control unit 131 stops supplying power, the servo mechanism 111 is driven to drive the target interface a to reset to a preset position, thereby automatically plugging and unplugging the target interface a and the matching interface B.
It should be noted that, when the target interface a is driven to move to the target position, the target interface a may be inserted into the mating interface B, that is, the target interface a is in an inserted state; the target interface a may be pulled out from the mating interface B, that is, the target interface a may be in a pulled-out state. And are not limited herein.
In one embodiment, the motion module 110 further includes a return spring 113.

Specifically, one end of the return spring 113 is mechanically connected to one end of the servo mechanism 111 moving in the inserting and extracting direction, and the other end of the return spring 113 is fixed at a position. When the main control unit 131 supplies power, the suction force generated by the servo mechanism 111 is greater than the elastic force generated by the change of the shape of the return spring 113, and the target interface a is moved to the target position; if the main control unit 131 stops supplying power, the suction force generated by the servo mechanism 111 disappears, and the elastic force of the return spring 113 drives the servo mechanism 111 to drive the target interface a to return to the preset position.
In one embodiment, optionally, when the target interface a moves to the target position, the target interface a is pulled out from the mating interface B; and when the target interface A is reset to a preset position, the target interface A is inserted into the matching interface B.
It can be understood that when the target interface a moves to the target position, the target interface a is pulled out from the mating interface B, that is, the control target interface a is pulled out from the mating interface B when the main control unit 131 supplies power, and the control target interface a is inserted into the mating interface B when the main control unit 131 stops supplying power, so as to avoid that the target interface a and/or the mating interface B are damaged when the main control unit 131 is powered off for a long time.

It will be appreciated that other devices or modules may also send test signals to the mating interface B. In addition, the device for controlling automatic plugging and the device for testing can be different devices. However, in this embodiment, the main control unit 131 controls automatic plugging and unplugging, tests the target interface a during plugging and unplugging, and can control plugging and unplugging and test through one device, so that the testing efficiency can be improved, and the testing cost can be reduced.
In one embodiment, the main control unit 131 is further configured to stop the plug control of the target interface a when receiving an exception signal sent by the target interface a to characterize that the function of the target interface a is abnormal.
Specifically, when the main control unit 131 receives the abnormal signal, the power supply to the motion module 110 is stopped through the control output terminal P3, and the motion module 110 stops moving, so that the fault site is reserved.
In this embodiment, when the main control unit 131 receives the abnormal signal sent by the target interface a, the plugging and unplugging control on the target interface a is stopped, and a fault site can be reserved, so that a technician can analyze the reason according to the fault site.
It should be noted that fig. 3 is a diagram of the motion module 110 and the target interface a separately, so as to better show the testing process of the target interface a and the mating interface B, but the target interface a is installed on the motion module 110.
In one embodiment, the master control unit 131 sends a high signal to the mating interface B through the test output terminal P7. When the target interface a is in the plugged-in state, the low level signal received by the main control unit 131 is used as the abnormal signal; when the target interface a is in the unplugged state, the high level signal received by the main control unit 131 is used as the abnormal signal.
In this embodiment, specifically, when the target interface a is inserted into the mating interface B, the test output end P7 of the main control unit 131, the mating interface B, the target interface a, and the test input end P5 form a loop, and when the main control unit 131 sends a high level signal to the mating interface B through the test output end P7, if the target interface a is tested normally, the test input end P5 should receive the high level signal, and if the target interface a is in an inserted state, the main control unit 131 receives the low level signal, it indicates that the target interface a is tested abnormally, and the test needs to be stopped. Similarly, when the target interface a is pulled out of the mating interface B, the test input terminal P5 should receive a low level signal, and if the main control unit 131 receives a high level signal when the target interface a is in a pulled out state, it indicates that the test is abnormal, and the test needs to be stopped.
