  • Connector, connector assembly, and circuit device
    Patent number: 10873148
    Abstract: A first terminal includes a to-be-held portion configured to be inserted, in a vertical direction, into a terminal holding hole. The outer surface of the to-be-held portion and the inner surface of the terminal holding hole formed in the first housing include: a contact region where the outer surface of the to-be-held portion and the inner surface of the terminal holding hole are in contact with each other; and a gap region where a reservoir space is formed between the outer surface of the to-be-held portion and the inner surface of the terminal holding hole. The contact region includes a partial region located on an exposed portion's side.

  • Push-button mechanism for ejecting an electronics card from an electrical connector
    Patent number: 6609918
    Abstract: An actuating mechanism for effecting the ejection of an electronics card from an electrical connector has a reduced cost, reduced component wear, simple assembly, and compact space-saving structure. The actuating mechanism includes a rotary shaft that engages with or disengages from an ejection mechanism for loading and unloading a card, and exerts an ejection force to the ejection mechanism when the rotary shaft engages with the ejection mechanism. Switching between engagement and disengagement is effected by rotation of this rotary shaft, and the rotation is effected by the interaction of wave-shaped cams provided on the rotary shaft and on an axially slidable pushrod.
