  • Patent number: 5476389
    Abstract: An electrical connector assembly has a socket body which is mounted on a printed board and is adapted for receiving a complementary plug with contacts. The socket body has a bottom and a pair of opposed side walls defining therebetween a cavity for receiving the plug. The socket body carries a plurality of connector contacts, each of which is bent to define an inner leg and an outer leg both extending from a bent. The inner leg extends along an inner surface of the side wall within the cavity for engagement with the contacts of the plug, while the outer leg extends downwardly from the bent along an outer surface of the side wall to define a terminal lead at its lower end. The terminal lead projects generally horizontally outwardly from the bottom of the socket body so as to be registered on a corresponding terminal site of a conductor pattern on the printed board and is welded thereto.

  • Patent number: 5433616
    Abstract: A low profile, surface-mounted receptacle includes a housing having a cavity defined at least in part by the interior surfaces of the sidewalls thereof. The interior surface of at least one sidewall has a groove, one wall of the groove being defined by an inclined portion. An electrical spring contact is received within the groove, the contact being of the curved, dual cantilever type having a first leg, a curved transition portion and a second leg. The contact being disposed to define a clearance space between itself and the inclined. The legs and curved portion responding to the introduction of a male plug by cantilever toward the inclined sidewall and undergoing a reduction in the radius of curvature, thereby displacing to an extent sufficient to exert a predetermined normal force on the plug, despite dimensional variations in the housing due to manufacture.

  • Patent number: 5425658
    Abstract: A card edge connector with a housing and electrical contacts. The electrical contacts are spaced from adjacent contacts at a center-to-center pitch of 0.025 inch. The contacts each have a middle section that is interference fit in a contact receiving channel of the housing. The middle sections each have a general ring shape with a center electromagnetic reduction aperture. The ring shape forms a structural truss to retain structural rigidity of the middle section to enable the interference fit to be made and, the center electromagnetic reduction aperture reduces capacitance between the closely spaced adjacent contacts.

  • Patent number: 5393234
    Abstract: The purpose of this invention is to offer an edge connector which requires less space for insertion of a card and has a reduced stress in the housing due to dissipation of mechanical stress. Accordingly, the invention comprises a C-shaped connector 1 having a housing that has a reception groove 8 and guiding grooves 10, 10' for a memory card 100. In the upper walls forming the guiding grooves 10, 10' protrusions 12, 14 are formed. These protrusions match indentations 108, 110 in the memory card. The memory card 100 can be inserted into the guiding grooves 10, 10; only when the protrusions 12, 14 and indentations 108, 110 are properly aligned. After that the memory card is moved along the grooves 10, 10' toward the contacts 70, 70' arranged in the main body 4 of the housing.

  • Patent number: 5391089
    Abstract: An electrical connector is disclosed. The connector is made up of first and second housings, one of which is male and the other female. The first housing contains one conductor or two or more opposed conductors. The conductor is made of an elastically deformable and resilient conducting substance. A second housing contains a substrate which carries a conductor in the form of an edge contact pad. The second housing also contains a camming surface or surfaces which interact with the conductor in the first housing. The first and second housings are brought together so that the conductor in the first housing lies opposite the contact pad in the second housing. The housings are then mated. On full mating, the conductor in the first housing is brought into contact with the contact pad in the second housing by the camming surface translates the lateral relative motion of the first and second housings into substantially transverse motion of the conductor in the first housing.

  • Patent number: 5387133
    Abstract: A terminal is provided which includes includes an a non-movable L-shaped base and a swan neck contact coupled to one end of the base. The terminal also includes a split dimple formed on a base of the terminal to provide a front-to-back alignment of the terminal inside terminal-receiving cavities formed in a socket housing. The split dimple also provides the terminal with a strong retention to the plastic body of the connector housing. The terminals are particularly useful in a SIMM socket. Adjacent terminals on opposite sides of the edge card are electrically isolated or independent from each other. By incorporating electrically independent contacts into a SIMM socket, the present invention permits twice as many I/O leads in the same amount of space compared to a conventional SIMM socket and doubles the number of pads per module.

The shorting contacts are edges of angled surfaces (36) on the respective electrical terminal members which are laterally reversed mirror images of each other. The respective edges confront each other in a substantially transverse configuration. Initial engagement between the respective edges is at an initial point contact (125) at a high stress. The edges thereafter wipe against one another and come to engage at a final point contact. The path from the initial point contact to the final point contact constitutes a line between the respective electrical terminal members.

    Abstract: In a connector comprising: a terminal having an electrically contacting spring piece which is accommodated in a surrounding wall in such a manner that it is allowed to protrude through an opening formed in the surrounding wall; and a connector housing into which the terminal is inserted, the spring piece has an electrically contacting portion confronted with the opening, and an slide portion bent in such a manner that it is away from the opening, and the connector housing has a depressing protrusion for depressing the slide portion. As the terminal is inserted into the connector housing, the depressing protrusion depresses the slide portion so as to cause the electrically contacting portion to protrude outside through the opening. Thus, the electrically contacting spring piece of the terminal is protectively held in the terminal until the latter is inserted into the connector housing.
