  • Publication number: 20080299840
    Abstract: An L-shaped contact includes a contact portion adapted to contact a mating object, a fixed portion to be fixed to a housing, and a connection portion to be connected to a connecting object, and a hole formed in a bent portion between the fixed portion and the connection portion. When the contact is fixed to the housing, the contact is inserted into the housing by pushing an end face of the hole. The L-shaped contact ensures a stable contacting surface area for being pushed by a jig and enables to bear a heavy-electric current to pass therethrough without adversely affecting miniaturization of a connector and extremely narrow pitches of the conductors.
