Example two
As shown in fig. 9, the difference between the present embodiment and the first embodiment is only that the limiting assembly includes:
a limiting groove 34 which is arranged on the inner wall of the sliding groove 25 from top to bottom, wherein the limiting groove 34 is provided with a lower end face;
the second stopper 35 extends outward from the top of the first housing 4 into the stopper groove 34, can slide in the stopper groove 34, and is stopped by the lower end surface of the stopper groove 34.
When the connector positioning device 3 is lifted upwards, the limiting groove 34 moves upwards relative to the second limiting block 35, and when the bottom surface of the second limiting block 35 contacts with the lower end surface of the limiting groove 34, the connector positioning device 3 cannot be lifted upwards, so that the connector positioning device 3 is limited, and the damage to parts caused by the overlarge lifting displacement of the connector positioning device 3 is avoided.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
