Patent number: 6942503Abstract: An electrical connector includes a dielectric housing having a receptacle for receiving a complementary mating connector. A plurality of conductive terminals are mounted on the housing and have contact portions exposed in the receptacle for engaging appropriate contacts of the mating connector. A metal shell is disposed about at least a portion of the housing. A shutter plate is movably mounted on the housing for movement between a closed position and an open position. In the closed position, the shutter plate substantially closes the receptacle to prevent inadvertent engagement of foreign objects with the contact portions of the terminals. In the open position, the shutter plate allows mating of the complementary mating connector. At least a portion of the shutter plate is conductive to dissipate static electricity at the receptacle. At least one spring is mounted on the housing for biasing the shutter plate toward its closed position.Type: GrantFiled: February 26, 2003Date of Patent: September 13, 2005Assignee: Molex IncorporatedInventors: Kenichi Yamaguchi, Mitsuo Fujikura

Patent number: 6250959Abstract: A connector is provided for terminating a plurality of generally parallel coaxial cables having fine conductor cores. The connector includes a dielectric housing having a slot. A plurality of terminals are mounted on the housing with contact portions spaced along the slot. A wire management member is insertable into the slot and includes a plurality of grooves for receiving the conductor cores and spacing the cores in alignment with the contact portions of the terminals. An actuator engages the wire management member and biases the conductor cores against the contact portions of the terminals.Type: GrantFiled: February 14, 2000Date of Patent: June 26, 2001Assignee: Molex IncorporatedInventors: Tomisaburou Yamaguchi, Mitsuo Fujikura, Hideki Iijima, Yoshiyuki Mizuno

Patent number: 5741154Abstract: An electrical connector is disclosed for connecting a flat cable. The connector includes a dielectric housing mounting a plurality of conductive terminals. The housing has a front end adapted for receiving the flat cable in engagement with the terminals, a rear end and opposite sides. An actuator is pivotally mounted on the housing for pivotal movement between a first position allowing insertion of the flat cable into engagement with the terminals and a second position biasing the cable against the terminals. An independent engagement part is mounted on the housing and includes a pivot about which the actuator is pivotable between said positions.Type: GrantFiled: September 24, 1996Date of Patent: April 21, 1998Assignee: Molex IncorporatedInventors: Mitsuo Fujikura, Shinsuke Kunishi, Minoru Fukushima

Patent number: 5695359Abstract: A zero force electrical connector is adapted for terminating a flat cable. The connector includes a dielectric housing mounting a plurality of conductive terminals. The housing has a first end adapted for receiving the flat cable in engagement with the terminals, a rear end and opposite sides. An actuator is mounted to the housing for movement between a first position allowing free insertion of the cable into engagement with the terminals and a second position biasing the cable against the terminals. Complementary interengaging stops are provided between the housing and the actuator near the rear end of the housing for limiting rotation of the actuator relative to the housing in a first direction. Complementary interengaging latches are provided between the housing and the actuator near the front end of the housing for preventing rotation of the actuator relative to the housing in a second direction opposite the first direction.Type: GrantFiled: February 20, 1996Date of Patent: December 9, 1997Assignee: Molex IncorporatedInventors: Mitsuo Fujikura, Minoru Fukushima, Shinsuke Kunishi, Masashi Seto

Patent number: 5460546Abstract: Disclosed is an improved electric connector having terminals for contacting two circuit elements (34 and 35). Each terminal includes a flat intermediate base mounting section (2) having projections (7) on its opposite sides, a first cantilever contact beam (3) integrally connected to one end of the intermediate base section (2) extending toward the other end of the intermediate base section (2), and a second cantilever contact beam (4) integrally connected to the other end of the intermediate base section (2) extending toward the one end of the intermediate base section (2). The first contact beam (3) has a contact point (8) resiliently pushed against the upper guide wall (23). This will insure that the conductor (35) is sandwiched between the upper guide wall (23) and the contact point (8) making a good electrical connection. Likewise, the second contact beam (4) has a contact point (10) resiliently pushed against the upper wall (24).Type: GrantFiled: February 24, 1994Date of Patent: October 24, 1995Assignee: Molex IncorporatedInventors: Shinsuke Kunishi, Mitsuo Fujikura

Patent number: 5145384Abstract: An electrical contact is disclosed for use in an electrical connector to be surface mounted to a printed circuit board. The contact includes an inverted U-shaped portion defining a pair of depending legs. One of the legs has a foot portion for electrical connection to an appropriate circuit trace on the printed circuit board. A terminal portion is turned upwardly from a distal end of the other leg for termination with an appropriate mating terminal. The contact is in the form of a one-piece metal component. In the preferred embodiment, the terminal portion of the contact is in the form of a terminal pin, with the pin and the legs of the inverted U-shaped portion of the contact all being generally parallel.Type: GrantFiled: July 29, 1991Date of Patent: September 8, 1992Assignee: Molex IncorporatedInventors: Kazushige Asakawa, Minoru Fukushima, Mitsuo Fujikura
