Contacts and electrical connecting apparatus using the same

摘要

An electrical connecting apparatus uses a plurality of contacts each of which includes: a principal portion having an outer face curved and directed to a conductive portion of a base plate and received in a recess and a slit of a housing; a front end portion continuous to the front end side of the principal portion and projected upward from the slit so as to be relatively pressed against an electrode of a device under test; and a rear end portion continuous to the rear end side of the principal portion and located in the recess. The front end portion of each contact is projected upward from the slit by the dimension of the thickness of the front end portion or more than that and has an arc-shaped front end face extend in the longitudinal direction of the slit.
