the sensor (7) is fixedly mounted to the block body (10) of the first moving block (1) and faces a reference surface (8 a) of the reference block (8) to detect a distance between the sensor (7) and the reference surface (8 a);

the distance of movement of the second moving block (2) in the first direction (Z) relative to the first moving block (1) is equal to the distance of movement of the reference surface (8 a) relative to the sensor (7).

15. The connector crimping apparatus of claim 13, wherein:

the sensor (7) is a laser distance sensor, an ultrasonic distance sensor or an infrared distance sensor.

16. The connector crimping apparatus of claim 1, further comprising:

and the driving device is connected with the first moving block (1) and is used for driving the first moving block (1) and the second moving block (2) to move together along the first direction (Z).
