  • Patent number: 6960095
    Abstract: Disclosed is an unlocking-proof PGA package socket which is so designed that upon the slide plate being put in its locking position for fastening a PGA package to the socket the longest vector of the circular cam member runs beyond the point of contact at which the cam member is put in contact with the slide plate, thereby allowing the kickback to push the cam member in the direction opposite to the direction in which the cam member turns toward unlocking position.

  • Patent number: 6860744
    Abstract: Disclosed is an improvement in a right-angled type of connector having a plurality of terminals parallel-arranged in its insulating housing, each terminal comprising a tail and a contact section integrally connected to the tail at right angles, the tail being to be inserted in a selected through-hole in an associated printed circuit board. The terminal has an intermediate crank-like section formed between its tail and contact section, thereby lowering the contact section toward the tip end of the tail. This allows the connector housing to be reduced in height.
