In one specific example, the drive assembly 1100 further includes a stop 1103, and the stop 1103 is used to limit the distance that the crimp assembly 1050 moves in the forward-rearward direction, and prevent the crimp assembly 1050 from moving forward too long to cause the crimp assembly 1050 to collide with the support plate 1040.

In one possible implementation, as shown in fig. 12, the third ram portion 1053 includes a connecting plate 10532 having an opening 10531, a cover plate 10533 secured in combination with the connecting plate 10532, and a hold-down 10535 located within the opening 10531 and secured to the cover plate 10533 by a resilient member 10534; the hold down 10535 is used to hold down the key assembly electrical connector portion to allow communication between the key assembly electrical connector portion and the connector 1082.
