Abstract: An elongated hollow housing is made of a conductive material. The housing includes an opened first end for receiving the male terminal and a second end connected to the power supply. A first contactor made of a conductive material is located in the housing. The first contactor contacts the male terminal received into the housing.

The second contactor contacts the male terminal when the male terminal is inserted into the housing. The second contactor is deformed to separate from the male terminal after the male terminal is separated from the first contactor when the male terminal is removed from the housing.

Abstract: A female terminal fitting (F) has a resilient contact piece (23) with first and second leaf springs (24, 29) connected by a folded portion (26). A base end (24A) of a first leaf spring (24) and an extending end (30) of a second leaf spring (29) are supported on a base plate (14). Thus, a high contact pressure can be ensured.

Abstract: Two resilient contact pieces (20A, 20B) have base ends (21A, 21B) coupled to each other and folded one over the other, such that the base ends (21A, 21B) are substantially in close contact. A pressing portion (24) presses the two base ends (21A, 21B) from the outside and prevents the base ends (21A, 21B) from opening. Thus, the two resilient contact pieces (20A, 20B) are held one over the other in proper postures.

A fold (20) is folded back from the front end of the bottom wall (13) and a resilient contact piece (18) extends back from the fold (20) to face the bottom wall (13). A bulge (23) on the resilient contact piece (18) includes a contact (25) for contacting a tab (T) of a male terminal fitting (M). The contact (25) is pressed by the tab (T) so that the resilient contact piece (18) is deformed with the fold (20) as a supporting point and an extending end (26) thereof contacts the bottom wall (13). The resilient contact piece (18) has a front narrowed portion (29) between the fold (20) and the contact (25) and a rear narrowed portion 30 between the contact (25) and the extending end (26).

Abstract: A zero terminal insertion force electrical connection assembly. A female terminal features a barrel having a floor, a roof and an opening. Connected to the floor is a tongue which curves inwardly and upwardly into the barrel, and has an interface surface located adjacent the roof when the tongue is in a relaxed state.

A zero insertion force member is slidably interfaced with the barrel such that at a first position, the boss feature projects fully through the aperture. However, when slid to a second position, the zero insertion force member presses upon the boss feature so as to cause the tongue to be resiliently depressed toward the floor and allow a male terminal to be slid receivingly into the barrel without any contact with the tongue.

Abstract: An electrical contact for attachment to an insulated wire includes an insulator crimp section (11) having a pair of insulation engaging arms (12a, 12b) which are offset from each in an axial direction of the wire. The insulation engaging arms include facing edges (38a, 38b) which are arranged to contact each other along a spiral track when the insulation engaging arms are press-bonded to the insulation of the wire. Inside beveled surfaces (18a, 18b) and outside beveled surfaces (28a, 28b) serve to guide the insulation engaging arms into position and to facilitate sliding contact between the facing edges (38a, 38b) during the press-bonding. The inside beveled surfaces (18a, 18b) also provide a gap (4B) which serves as a relief area for compressed insulation. As a result of the press-bonding, the insulation engaging arms (12a, 12b) are formed into an integral unit and are strongly fastened to the insulation of the electrical wire.

Abstract: Upon coupling a shield connector 10 to a partner-side connector 50, the cam followers 37 of the shield connector 10 are made engage with the cam grooves of a lever 56 provided at the partner-side connector 50, and the lever 56 is rotated. Then, the shield shell 55 covering the outer surface of the tip end side of the terminal housing tube 52 moves into the fit-in portions 15 of an inner housing 12, so that the belt portions 19B of belt-shaped elastic pieces 19 are applied with a force directed to the inner side of an inner housing fit-in hole 34 due to the sliding-contact resistance between the belt-shaped elastic pieces and the shield shell 55. However, according to the embodiment, the sliding-contact resistance acts as a force of pulling the belt-shaped elastic pieces 19.

Abstract: An electrical connector, of the pin/socket type, wherein the pin is removable from the socket. Ordinarily, physical movement of the connector causes the contact points between the pin and the socket to redistribute themselves, with deleterious results. The invention constrains the pin to remain in contact with two rail surfaces defined in the socket. As a visual analogy, the pin can be viewed as a large cylindrical tank, supported by railroad tracks parallel with the tank's axis. Cradling the pin in this manner reduces, or eliminates, redistribution of contact points.

This isolates crimping forces of the barrel from the tubular body which houses the leaf spring contact.

Abstract: A terminal fitting has a bottom wall (15). A curved portion (21) is folded back at a front end (15F) of the bottom wall (15). A touching portion (22) extends back from the curved portion (21) and is in contact with the bottom wall (15). A contact portion (23) extends back from the touching portion (22). The contact portion (23) is displaced resiliently about the rear end (22R) of the touching portion (22) in response to contact by a male tab (T), and a resilient restoring force of the contact portion (23) ensures high contact pressure.

Thus, there is no possibility of concentrating a stress on the curved portion (21) and the height of a terminal fitting can be reduced by reducing a radius of curvature of the curved portion (21).

Abstract: A female terminal fitting has a wall member which is not weakened as a result of cutting away bending regulating members therefrom, these bending regulating members preventing the excessive bending of a resilient contacting member. Anterior and posterior bending regulating members 26F and 26R are formed by cutting away a portion of a fitting member 11. These bending regulating members 26F and 26R prevent a resilient contacting member 20 firm bending excessively. The anterior bending regulating members 26R are formed on a base wall 13, and the posterior bending regulating members 26F are formed on side walls 14. These bending regulating members 26F and 26R are formed on differing walls. Consequently, compared to the case where both bending regulating members 26F and 26R are formed on a single wall, the opening area formed by cutting away the bending regulating members is smaller on each wall, and accordingly the strength of the walls is maintained.
