  • Patent number: 10522932
    Abstract: In a terminal holding structure of a connector, a straight portion of a terminal is press fitted into a terminal holding hole formed on a terminal holding wall of a resin housing, so as to be held therein. At least a pair of projecting portions projecting to both sides in a direction orthogonal to a press-fitting direction is formed on the outer surface of a region of the straight portion of the terminal corresponding to the terminal holding hole. The projecting portions are formed with the cross-section orthogonal to the straight portion including a wedge-shaped dent at a distal end. The dents are formed such that a dimension between bottom portions is larger than the dimension of the terminal holding hole at the position into which the projecting portions are press fitted. This enhances the holding power to the terminal, and enables the terminal to be held stably.

  • Patent number: 4691979
    Abstract: A compliant, press fit, electrical contact includes a relief groove which forms an area of reduced cross sectional thickness to provide a stress concentration, and thus a controlled region of plastic flow, to create a plastic-elastic hinge. When the contact is inserted into a plated through hole in a printed circuit board, the hinge elastically deforms until a predetermined push-in force is reached, at which time a controlled plastic flow begins. Once the point of plastic flow is reached, the amount of additional push in force required for additional deflection of the hinge is greatly reduced, so that smaller hole sizes may be accommodated with a relatively small additional push in force. However, the required minimum pull out force is maintained for the entire range of hole sizes, since elastic energy remains stored in the hinge, even after plastic flow begins. The contact is manufactured through a series of simple coining and punching operations, so that complex rounding and rolling operations are avoided.
