  • Patent number: 10559919
    Abstract: A connector includes a terminal-equipped electrical wire, an inner housing, an outer housing, and a front holder. The terminal-equipped electrical wire includes an electrical wire and a terminal, the terminal having a box-shaped portion configured to fit with a mating terminal in a fitting direction intersecting with an extending direction of the electrical wire. The inner housing includes a terminal accommodating chamber. The outer housing includes an electrical wire leading-out opening and a housing fitting opening. One or more pressing protrusions are provided on at least one of the terminal and the front holder. When the outer housing is fitted to the mating connector, the one or more pressing protrusions are elastically deformed by a fitting pressing force acting on the front holder to press and urge the box-shaped portion toward inside of the terminal accommodating chamber.

  • Patent number: 6328579
    Abstract: An electromagnetic shield connection mechanism according to the present invention is for a structure in which a housing wall is fixed to a equipment by inserting a bolt through a collar fitted in a hole formed on the housing wall. The electromagnetic shield connection mechanism according to the present invention is characterized in that a contact member connected to a metal shield lies between the collar and the equipment so that the collar presses the contact member tightly against the equipment, resulting in that a secure electromagnetic shielding is always achieved by thus improved contact between the metal shield and the equipment.
