Abstract: An electric connector is comprised of: a housing; a clamper for clamping a multicore cable formed with a plurality of sheathed cable elements bound by an outer jacket, a predetermined length of the outer jacket at an end thereof being removed; and a contact holder accommodated and held in the housing, a portion of the contact holder projecting from the housing being adapted to be inserted into a mating connector. The clamper includes a clamper body for clamping the outer jacket and a wing-like portion projecting radially from the clamper body. Contacts are fitted in the contact holder in such a manner as to be respectively connected to tips of core wires which are exposed with portions of respective sheaths of the plurality of sheathed cable elements removed.

Abstract: An electrical connector is provided which, when attached to a printed circuit board, will not cause removal of a cream solder that has been applied to the circuit board, and which will not flaw the surface of circuit portions. The connector has a resilient arm which undergoes elastic deformation to flex contacts perpendicularly away from the surface of the circuit portions when the circuit board is inserted into the connector. The resilient arm is restored to its original shape when the connector has been correctly fitted on the circuit board, thereby allowing the contacts to contact predetermined circuits. In another embodiment, the resilient arm is replaced by a frame member which is urged into the connector body by the circuit board. This causes the contacts to part perpendicularly from the surface of the circuit portions.

Abstract: A printed circuit board mounted connector includes an insulating body and a shield plate. The insulating body incorporating contact terminals and adapted to be mounted on a printed circuit board. The shield plate covers a front surface and both side surfaces of the insulating body. The shield plate has bent portions which are formed by partially cutting and bending a shield plate portion corresponding to the front surface of the insulating body and extend toward the insulating body to define a substantially circular opening for receiving annular shield contact terminals of a mating connector, and shield springs which are formed by partially cutting and bending shield plate portions corresponding to both the side walls of the insulating body and extend away from the insulating body. The shield springs are brought into contact with a ground plate extending in a direction perpendicular to a surface of the printed circuit board.

Abstract: A connector including a housing having a first surface and a plurality of first bores extending from the first surface for respectively receiving coaxial pins. The connector further includes a flat member made of an electrically conductive material and disposed in the housing so as to face the first bores, and first arms are formed from portions of the flat member which are associated one-to-one with the first bores for electrical connection to respective outer conductors of the coaxial pins. The connector further includes a plurality of second bores extending toward the flat member from a second surface of the housing which is opposite to the first surface for respectively receiving ground pins, and second arms formed from portions of the flat member which are associated one-to-one with the second bores for electrical connection to respective ground pins.

Abstract: A thin-type coaxial connector and a coaxial multicore receptacle used together with the thin-type coaxial connectors are disclosed herein. The thin-type coaxial connector comprises a female central contact mechanically and electrically connected to a central conductor of coaxial cable by press-deforming, an insulator holder of a discrete sleeve fitted onto the central contact and an insulator sheath layer of the coaxial cable, a ferrule fitted onto an outer surface of the coaxial cable and covered with an outer conductor of the coaxial cable folded thereon, and an outer conductor sleeve closely fitted onto the insulator body and said folded outer conductor to clamp the outer conductor by the outer conductor sleeve and the ferrule.

Abstract: An electronic device packaging structure, in which a plurality of electronic circuit packages are arrayed on one side of a back panel with their signal input/output terminals projecting out onto the other side of the panel and each connected to one end of one of plural wiring cables. The other ends of the wiring cables are connected to relay connectors, which are fixed to a common frame, constituting a back panel system. A pair of such back panel systems are detachably coupled together via the relay connectors.

Abstract: A connector apparatus for making a connection between a signal line and an external circuit is disclosed which comprises a connector body having first and second pairs of terminals, each pair of terminals comprising a pair of contact pins, a first connector element having two terminals each attachable to and detachable from one end of each of the pair of contact pins of the first pair of terminals, the two terminals being connected to the signal line, a second connector element having two terminals each attachable to and detachable from one end of each of the pair of contact pins of the second pair of terminals, and terminating resistor connected between the two terminals in the second connector element, in which the other end of each contact pin of the first and second pairs of terminals is used as an external circuit connector terminal.

Abstract: A connector device is disclosed which can branch or terminate signal lines for making a mutual connection among a plurality of units. The connector device includes switches between signal line connection terminals so that the connector may serve as both a branch connector and a strap connector. A hook is provided on a body case of the connector device and usable in interlock with the switch. A groove engageable with the hook is formed on a connector element case for external circuit connection so that through the selective engagement of the hook with the groove the element case is prevented from being inadvertently detached from the body case. During the detachment of the element case, the contact pin is placed in a short-circuited state at all times. A terminating connector device is also disclosed which is comprised of a combination of a connector body with first and second connector elements. The connector body includes first and second pairs of terminal.

Abstract: A connector for connection of a coaxial cable comprises a cylindrical holder composed of a support member and a lid member of semi-cylindrical configurations made of insulator material, and a center contact stored and held in the front end portion of the cylindrical holder. One end of the coaxial cable is held in a cable holding section in the rear of the center contact, a core wire of the coaxial cable is connected to the center contact, a ferrule is disposed in an opening formed at the cable holding section, an exposed outer conductor portion of the coaxial cable is folded and disposed on the ferrule and connected electrically thereto, the cylindrical holder is fitted and inserted in a metallic cylindrical body, and the ferrule is elastically deformed thereby to electrically connect the cylindrical body and the outer conductor together.

Abstract: A coaxial multicore receptacle is provided which has a plurality of ground pins set upright on an insulating substrate and arranged in a matrix pattern, a plurality of signal pins set upright on the substrate each being located at the center of each box of the matrix pattern, first metallic lattice boards provided perpendicularly to the substrate each being positioned correspondingly to and above each column of the ground pins, and second metallic lattice boards provided perpendicularly to the substrate each being positioned correspondingly to and above each row of the ground pins. The first and second lattice boards cross one another orthogonally to define angular coaxial contact insertion holes surrounded by the boards and arranged in the matrix pattern. Each of the first lattice boards is formed with notches in the end portion on the side of the substrate to provide ground pin contact springs which are in elastic contact with the corresponding ground pins.
