Abstract: A suitable contact state is attained by an always stable contact pressure between a male contact and a female contact which form a tuning fork type contact. For a contacts providing a tuning fork type contact 2 that attains a contact state by inserting a male contact 4 between a pair of beams 6a and 6b provided on a female contact 6, in the connected state, male contact 4 and female contact 6 are arranged so as to maintain a state wherein the width direction of the male contact is angled relative to the direction of separation of the beams 6a and 6b.

Abstract: A low insertion force terminal comprising a female terminal (12) and a male terminal (11), the female terminal 12 being provided with a bottom (14) soldered to wiring, and a pair of opposing upright parts (15,16) extending from said bottom (14) in a cantilevered beam shape; and wherein an extended part (19) that projects on the distal end (16a) of one of said upright parts (16) farther than the distal end part (15a) of the other upright part (15) in the widthwise direction is provided, and a male terminal supporting part (18) that grasps and supports the male terminal (11) is provided at a position in proximity to said extended part (19) of said pair of upright parts (15,16).

Abstract: An electric connector of the present invention is directed to alleviating a stress in housings of an electric connector. In the housings 16 of the electric connector, slots 44, 46 are formed to receive associated terminals. Projections 48a, 48b are formed in a staggered fashion on the oppose wall portions of the slot. The terminal 24 has a retaining section 28 against which the projections 48a, 48b abut and a projection 29 abutting against one wall surface. By the projection 29 and projection 48a on the wall surface against which the projection 29 abuts, a projection 48b on the other wall surf ace supports a force urging the terminal 24, so that the terminal 24 is retained in place in the slot 44.

Abstract: An electric connector is provided which can be highly accurately positioned to a location to be aligned. An electric connector set comprises a pair of insulating housings 10, 10a so formed as to have a plurality of openings 14 arranged in an array and a plurality of projections 18 each extending into the associated opening, female terminals 24 made of metal and each detachably fitted over the corresponding projection 18 of one of these housings, having a solder ball 30 and soldered to an IC package p through each solder ball, male terminals 34 each having a contact section 38 provided around the projection 18 of the other housing 10a and engageable with the corresponding female terminal 24 and a lead section 36 electrically connecting its housing bottom side 22 to the contact section 38, and solder balls 40 attached to the lead section 36 at the bottom surface on the housing.
