An electrical connector includes a connector main body made of an insulating material for attaching an end portion of a pair of single wires untwisted at an end portion of a twisted pair cable; and a shell member to hold the untwisted portion. The shell member includes a base portion made of a conductive material to dispose the connector main body at the front end side and the untwisted portion at the basal end side; a cable holding portion made of a conductive material to hold the single wires at the untwisted portion for positioning the single wires parallel to each other and close or contact to each other; and a cover portion provided on the base portion to have at least the untwisted portion and the cable holding portion between the cover portion and base portion.

Electrical connector and method of connecting twisted pair cable to the electrical connector

A male terminal unit,(female terminal unit,) is made by providing core wires,-,and,-,of a shield cable,(,) in a male (female) conductor receiving channels,and,which are provided in a male holding block,(female holding block,) such that they are held at the engaging shoulders,-,and,-,placing the male holding block,(female holding block,) on a male insulation block,(female insulation block,) such that the core wires,-,and,-,are connected under pressure to the press-connection sections,-,and,-,(female press-connection section,-,and,-,) of the male terminal,-,and,-,(female terminals,-,and,-,).

Electrical connector system

A plug connector (A) comprises a connector housing (,A) having a plugging section (,) with an end face (,) having at least one contact (,) forming a connector body (,), left and right shields (,A,,B) put into left and right shield insertion slots (,A,,B), a linking piece (,) cut off to separate the left and right shields to mount a shield member (,) in the connector body.

Shield connector

A multipole waterproof connector comprises a connector body (1) consisting of a connector housing (7) and a plurality of press-fit terminals (8) attached to the connector housing, a press-fit or insulation-displacement block (2) consisting of an organizing protector (4), a multihole wire seal (5), and a retainer (6), a plurality of cables (3) put through the cable insertion apertures (30, 24, 18) of the retainer, the wire seal, and the organizing protector and bent at an end (3a) into the lateral cable insertion slots (22A, 22B), wherein the press-fit block is fitted into the connector body such that the press-fit or insulation-displacement portions of the press-fit or insulation-displacement terminals are press-fitted to the cables for connection by insulation displacement.

Multipole waterproof connector

The electrical connector includes a housing (1) having a cavity (2); female terminals (7) having a support section (7A) supported by the housing and a flexible section (7C) extending from the support section and having a contact portion (7C1); protective walls (3) extending in the cavity and having separation sections (3B) and a connection section (3C) for connecting the separation sections on the front side to form accommodation spaces (3A) for housing the flexible sections (7C) such that the contact portion projected from the accommodation spaces.

Electrical connector

A waterproof connector includes a housing having front and rear openings; a terminal unit provided in the housing and connected to a cable; and a watertight closure for closing the rear opening of the housing through which the cable is taken out. The watertight closure includes a bowl-like retainer attachable to the rear opening of the housing, the retainer having a bottom with a through hole for taking out the cable and a molding section on the bottom and a plurality of linkage apertures through the molding section, and an elastic seal secured within the retainer by securing portions of the elastic seal provided within the molding section and the linkage apertures and having a second through hole concentric with the first through hole.

Waterproof connector

An electrical connector assembly includes a support bracket (5) to be attached to a conductive object (90) and an electrical connector (1) mounted on the support bracket. The electrical connector includes a dielectric housing (3); at least one terminal unit (4) connected to a shield wire of a shielded cable (38); a ground terminal (6) in contact with the terminal unit; and a ground plate (87) mounted on the support bracket for interconnecting the ground terminal to the conductive object, thereby grounding the shield wire to the conductive object.

Terminal for an electrical connector

Electrical connector housing

An electrical connector consisting of a connector socket (1) having a rectangular socket block (3) and a connector plug (2) having a rectangular plug block (13). The rectangular socket block includes a pair of lock recesses (8) on opposite sides thereof, each having a pair of lock shoulders (9, 10) and a cutout (11) in a front portion thereof; and a pair of sloped surfaces (12) in opposite front sides thereof. The rectangular plug block includes a pair of lock arms (14) having a base portion (15a) extending backwardly from front ends of opposite sides of the plug block and a front portion (15b) extending backwardly and outwardly from the base portion, the base portions having a pair of lock projections (18, 19); a pair of lock arm receiving recesses (20) formed on opposite sides of the plug block; and a pair of end projections (21) extending outwardly from a rear end of the plug block to define an end of the lock arm receiving recesses.
