Abstract: A flat cable connector firmly holds a flat cable in the receptacle without complicating the construction of the connector. It reliably and precisely achieves the vertical and horizontal positioning of the flat cable with respect to the contact terminals of the receptacle. The flat cable connector comprises a roughly U-shaped locking body removably attached to the ends of the flat cable and having a pair of side frames each formed with a slit and with a locking projection and a front frame connecting the front ends of the paired side frames, and a receptacle having engagement portions engaged by the locking projections, wherein the flat cable is electrically connected to the receptacle by inserting the flat cable attached with the locking body into the receptacle.

Abstract: An IC socket comprises a socket body including a plurality of contacts for interconnecting an IC and a wiring board. Each of the contacts comprises a contacting arm including an upper end contact portion for a lead of an IC to overlie and contact, and a lower end contact portion including a downwardly facing projection capable of abutting with a wiring portion of the wiring board, and a pressing element projecting backwardly of the contacting arm from an area in the vicinity of a connecting portion between the projection and the contacting arm. The projection forming the lower end contact portion is received in an upwardly and downwardly open through-hole formed in the socket body, so as to be subjected to abutment with the wiring portion.

Abstract: A photoelectric transducer includes a conductive case having an optical connector receptacle and circuit board forming a photoelectric transducer circuit. Conductive stands are erected from the bottom of the conductive case to bridge-support the opposite ends of the circuit board. The stands have first grounding terminals connected to grounding lines of the circuit board and also second grounding terminals penetrating the conductive case for outward projection. The positioning and assembling of the circuit board can be simplified, a shield structure can be readily formed, and it is ensured that the connection terminals are out of contact with the conductive case. With this structure, the photoelectric transducer can be rendered compact.

Abstract: A photoelectric converter comprising a receptacle having therein a photoelectric converting element, and an optical plug. The optical plug is inserted into the receptacle such that the optical plug and the photoelectric converting element are held in opposing relation to each other. The photoelectric converting element is received in a shielding case, and the shielding case with the photoelectric converting element therein is received in the receptacle. A lighting port is formed in a side plate of the shielding case, and the optical plug and the photoelectric converting element are held in opposing relation to each other in the lighting port. A shielding terminal is mounted on the shielding case such that the shielding terminal is exposed from the receptacle.

Abstract: A sleeve is fixedly fitted onto a terminal of an optical cable, and a disengagement preventing claw formed on the sleeve by cutting and raising its peripheral wall is brought into engagement with an inner surface of a recess which is formed in an inner surface of a cable receiving port of a connector housing. With this construction, the optical cable can be connected to the connector housing without using the conventional plug.

Abstract: A cable fixing mechanism in a multicore type optical fiber cable connector has an outer shell holding cylinder for holding an outer shell of a terminal of a multicore type optical fiber cable press fitted to an outer surface thereof, a high tensile body press fit sleeve extending from a central portion of one end face of the outer shell holding cylinder and adapted to permit a high tensile body projecting from the terminal of the multicore type optical fiber cable to be press fitted to an inner surface thereof, and a plurality of outlet ports formed in a periphery of the high tensile press fit sleeve at the one end face of the outer shell holding cylinder and adapted to lead out the plurality of optical fibers therethrough.

Abstract: An optical fiber cable comprising an optical fiber, an inner insulator, tension resistant fibers and an outer insulator is fixed to a plug comprising a male plug member and a female plug member which are helically meshed with each other by driving the male plug member into the female plug member and provided with respectively abutting surfaces. The tension resistant fibers are divided into a plurality of bundles, which are extended outwardly from between the inner and outer insulators. In this state, the male plug member is screwed into the female plug member, thereby firmly clamping the outwardly extended bundles of tension resistant fibers between the abutting surfaces of the male and female plug members.

Abstract: An IC socket for a flat IC package comprises a socket substrate, a cover member, a rotary lever, and a locking/unlocking mechanism so as to obtain stable, reliable contact and stable, easy release of contact between the conductors of the flat IC package and the contact pieces of the IC socket. The locking/unlocking mechanism makes use of sliding movement of the cover member on the socket substrate on the basis of the rotation of the rotary lever.
