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 includes an insulating housing (100) consisting of a front section (111) and a rear section (112), the front section having a cylindrical contact support section (120) with a plurality of contact apertures (121) extending along its longitudinal axis and the rear section having a rear cavity (119) in a lower portion thereof; a plurality of L-shaped contact elements (300) each having a contact portion (301), an intermediate portion (302) extending rearwardly from the contact portion, and a terminal portion (303) extending downwardly from the intermediate portion, the contact portion being fitted into the contact aperture; and a block member (200) having a plurality of lateral channels (201) for receiving the intermediate portions and a plurality of vatical apertures (202) for receiving the terminal portions, the block member being fitted into the rear cavity so that the intermediate and terminal portions are fitted into the lateral channels and the vertical apertures respectively.

Abstract: An electrical connector which includes an insulating housing (30) containing a plurality of contacts (40); a cylindrical member for enclosing and supporting the insulating housing; and an insulating jacket (50) molded around the cylindrical member and a terminated section of a cable (70). The cylindrical member is divided into two semi-cylindrical sections (10, 20) in a plane parallel to its axis. The semi-cylindrical section (10) has a recessed joint edge or mortise and the semi-cylindrical section (20) has a projected joint edge or tenon corresponding to the recessed joint edge.

Abstract: A mounting structure includes an insulating housing (10) having an annular recess (14) extending rearwardly from a front end thereof for receiving a shell member of a mating connector; a metal end face protection member (40) attached to the front end and having a circular opening (41) for receiving the shell member; a pair of attachment sections (43) extend rearwardly from opposite sides of the end face protection member; a pair of leg members (45) extending downwardly from lower edges of the attachment sections to be secured to a printed circuit board (50); and a latch device (13B) provided within the insulating housing for engagement with the attachment sections whereby the end face protection member is locked to the insulating housing.

Abstract: An electrical connector has an insulating housing having an annular recess for receiving the shell member of a mating connector; a cylindrical shield member fitted in the annular recess, which includes shield contacts extending in radial directions from a front edge of the shield member; a detachable end face protection member attached to the front end of the insulating housing for protection thereof, which includes an latch member for latching the detachable end face protection member to the front end, whereby the shield contact comes into contact a backside of the end face protection member.

Abstract: An electrical connector includes an insulating housing having an annular recess extending rearwardly from a front end thereof and a shield member having a cylindrical wall fitted into the annular recess, a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, and a leg member for connection with a shield circuit of a printed circuit board. The shield member has a plurality of first cantilever contacts bent outwardly and then inwardly forming an outward projection for contact with a metal shield provided on an inside of a mating shell member and a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of the mating shell member.
