  • Patent number: 8641439
    Abstract: A simple structure capable of preventing a cam part of an actuator from coming out of position when the actuator is in an open position. The cam part 12a of the actuator 12 for rotating contacts 13 mounted inside an insulating housing 11 is provided with an engaging surface 12a2 which is a flat surface that faces cam lock protrusions 13a2 of second contact beams 13a when the actuator 12 is in the open position. Upon an external force or the like acting on the cam part 12a to come out of cam rotation recesses 13b3 when the actuator 12 is in the open position, the engaging surface 12a2 of the cam part 12a abuts on and makes locking engagement with the cam lock protrusions 13a2, so that the actuator 12 is prevented from coming out of position.

  • Publication number: 20140030935
    Abstract: A connector terminal includes a main body, a support leg, and a resilient portion. The main body includes a contact portion making contact with one side of a male connector terminal of a male electric connector, a spring portion facing the contact portion and making contact with the other side of the male connector terminal, a support portion supporting the spring portion, and a space-limiter restricting a space between the contact portion and the support portion from spreading. The support leg is adapted to be fixed at one of ends thereof. The resilient portion connects the other end of the support leg and the contact portion to each other and is resiliently deformable in accordance with deflection of the main body.

  • Patent number: 8628355
    Abstract: [Problem] To extremely simplify the configuration of an electrical connector by omitting a circuit board and an electrical connector, etc. of a mating counterpart. [Solution] A single plug connector 10 is directly mated with a wall part of a product chassis MF. In a mated state of the single plug connector 10, a contact part of a contact 12 is brought into contact with a contact part of a wiring pattern CP exposed from an inner-peripheral wall part of a mating hole MFa. Therefore, electrical connection of a signal transmission medium can be established by a simple configuration without the intermediation of a conventionally-used circuit board and an electrical connector serving as a mating counterpart mounted on the circuit board.

  • Patent number: 8602812
    Abstract: It is made possible with a simple configuration to electromagnetically shield connection leg portions disposed below a signal transmission medium immediately when both connectors are fitted to each other. A connector main body portion are preliminarily provided with a terminal portion of the signal transmission medium and a transmission-medium-side shield cover that extends from between the another connector (second connector) and the connection leg portions on a transmission-medium side, and the connection leg portions on the transmission-medium side disposed below the signal transmission medium (thin coaxial cables) is covered from above with the transmission-medium-side shield cover when both the connectors are fitted to each other, so that electromagnetic interference (EMI) is successfully prevented from occurring.
