  • Patent number: 9118130
    Abstract: A low insertion force female terminal that is configured to make electrical contact with a male pin. The terminal includes a spring portion configured to be deflected by the pin as the pin is inserted into the terminal. The spring portion is also configured to urge a contact feature formed into the spring portion toward the pin to make electrical contact with the pin. The contact feature is characterized by an asymmetrical shape configured so a leading-edge ramp angle of the contact feature is less than a trailing-edge ramp angle of the contact feature. The asymmetrical shape reduces the peak insertion force for the terminal when compared to terminal designs that have symmetrically shaped contact features with similar dimensions.

  • Patent number: 8333622
    Abstract: A terminal is used in an electrical connector and receives a matable contact member. The terminal has a receptacle contact section has a bottom wall, an upper wall, and a primary and a secondary spring beam, or member. The primary member extends from a bottom wall and is bent back into the receptacle contact section. The primary member has an upper surface facing the upper wall and a lower surface opposite the upper surface. The primary member includes a free end that is spaced from the upper wall a distance less than a thickness of the matable contact member. The secondary member is formed from the bottom wall that extends into the contact section and includes a free end disposed beneath the lower surface of the primary member in an overlapping, spaced relationship thereto remote from the free end of the primary member.

  • Patent number: 7955104
    Abstract: A shorting clip terminal connector assembly electrically shorts together terminals in a first connector body dependent on connection status of a first and a second connector body. A shorting clip terminal disposed in a shorting clip terminal cavity in the first connector body receives a protrusion disposed on the second connector body. When the second connector body is mated with the first connector body, the protrusion engages a lift element of the shorting clip terminal in the shorting clip terminal cavity thereon and urges the lift element to lift contact elements of the shorting clip terminal away from the terminals in the shorting clip terminal cavity enabling insertion of protrusion side walls intermediate the contact elements and the terminals in the shorting clip terminal cavity. The contact elements of the shorting clip terminal do not make electrical contact with the terminals and the protrusion side walls further shield the contact elements from making electrical contact with the terminals.

  • Patent number: 7347738
    Abstract: A low profile electrical connector assembly has terminals attached to insulated electric cables that are disposed in topless slots of a connector base. Each terminal has two longitudinally spaced retention slots. The connector base has two transverse grooves that extend through sidewalls of the topless slots to provide terminal retainers that engage the forward retention slots to retain the terminals in a longitudinal direction. The connector base has a third transverse groove that extends through the sidewalls of the topless slots with selected sidewalls having undercuts for retaining a bottomless connector cover. The connector cover has a face plate that has a plurality of apertures that align with the topless slots, a lower ledge, and a depending lock bar. The lock bar is disposed in the third transverse groove and extends through the rearward retention slots to further retain the terminals in the longitudinal direction.

  • Patent number: 6692316
    Abstract: A high current terminal blade connection system adapted for automotive environments, which provides environmental sealing includes a female connector and a male connector. The male connector includes a male power terminal having a contact blade and a means for connecting a power cable thereto. The female connector includes a female power terminal with a terminal blade seat for contactibly receiving the contact blade of the respective male power terminal. A contact insert is inserted within the female terminal and is the direct receiver of the male terminal contact blade. The contact insert includes dimples to provide stability and additional contact points to improve the electrical performance of the connection, and contact vanes to accept the mating male terminal blade for an in-line and right angle direction termination with the mating terminal blade. This design allows one female terminal and one contact insert for two different mating directions, thus eliminating the need for any additional parts.

  • Patent number: 6527573
    Abstract: A slide contact electrical connector preferably for an oxygen sensor is assembled in such a way as to protect the precious metal surface of multiple contact pads of an edge card 28. The edge card 28 is encased by a ceramic capsule 30. Trailing portions 54 of terminals 20 are laterally inserted into longitudinally extending channels 52 of a core 22 being radially and axially locked in place. The terminals 20 extend forward from the core 22 and are positioned about the trailing end 42 of the edge card 28 from a longitudinal direction. A collar 26 compresses the terminals 20 against the edge card 28 from a lateral direction thereby making the electrical contact. A shield 18 encircles the capsule 30, collar 26, terminals 20 and core 22 thereby protecting the electrical connection integrity. A seal 16 is disposed at a trailing end of the shield 18 penetrated by a plurality of insulated electrical wires 14.

  • Patent number: 6208233
    Abstract: An improved IDC trim resistor connector assembly made up of a generally open top cup shape connector with side wall slots and an interior first array of terminal posts arranged for passage therethrough of a first lead wire of sensor circuitry. A first stamped metal IDC terminal is push-on mounted on the terminal posts for IDC cradling and electrically and mechanically receiving and connecting to the first lead wire. A conventional trim resistor substrate is loose mounted but accurately positioned on the connector bottom wall and has an “E” pattern of resistive material adapted for center leg laser trimming to calibrate the associated sensor circuitry. A first IDC terminal spring leg overlap contacts one side leg of the trim resistor E-pattern and thereby spring clamps the resistor substrate. A cover is snap-latch mounted on the connector and has an access opening to enable laser trimming of the trim resistor after cover installation.
