Abstract: A contact for a plug connector has: a housing; and a primary lance which projects obliquely outwardly over the housing counter to a plug-in direction and which is inwardly deflectable for restraining the contact plugged into a contact chamber of a plug connector. The primary lance has both a stiffened region and a resiliently deformable region which is curved and extends at least partially in the plug-in direction. The stiffened region has a crimp that extends in the longitudinal direction. A supporting region is additionally provided, against whose contact surface the primary lance rests in response to a tensile load on the contact.

Abstract: It is aimed to provide a connector terminal including a silver layer on a surface of an electrical contact portion, having a reduced coefficient of friction of a surface and excellent in practicality and productivity and provide a method for producing such a connector terminal. A coating layer made of a silver layer and a film formed by bringing the silver layer into contact with a solution containing thiol and benzotriazole is formed on a contact portion of a connector terminal to be electrically brought into contact with another electrically conductive member. A solvent of this solution is preferably water and the thiol is preferably octadecanethiol.

Abstract: A contact is provided for latching in a contact chamber of a plug connection element. The contact has a contact box haying an upper wall, a lower wall, and two opposing side walls. A primary locking lance protrudes resiliently diagonally outward from the upper wall. To protect the primary locking lance against harmful plastic deformations due to externally attacking forces, at least one of the side walls, in an area laterally adjoining the primary locking lance, is configured to protrude outward beyond a plane of the upper wall. An outside edge is bent toward the primary locking lance, so that it overlaps a side edge of the primary locking lance so that it counteracts outward bending of the primary locking lance in a form-locked manner.

Abstract: A terminal fitting (10) has a rectangular tubular box (11) with an open rear end.

Abstract: Unipolar or multipolar electrical plug connectors include contact carriers having contact chambers, into which contact elements can be inserted. These contact elements latch with so-called snap-on lances. In the present SYSTEM, the latching is produced by a part of the contact element with a snap-on lance, a smooth outer geometry of the contact element being present in the assembled state, but by latching of a non-resilient snap-on lance within the contact chamber. Consequently, the advantages of the snap-on lance locking mechanism unite with those of the clean-body construction.

Abstract: An electrical connector assembly has an elongated insulative housing and a plurality of signal contacts secured in corresponding passageways defined in the housing. Each signal contact has a retention portion retained in the passageway, a contact portion extending from the retention portion and a soldering portion extending from the retention portion. The contact portion defines a first face exposing an exterior of the passageways and a second face opposite to the first face. Wherein each of signal contacts defines a recess on the second face. The signal contacts become thinner so as to prevent signal contacts from crosstalk and improve high frequency performance.

Abstract: A male terminal fitting (20A) is inserted into a cavity (11) in a housing (10) from the rear, and has a tab (26A) that passes through an open portion (16) of a front wall (14) of the cavity (11). A proximal portion (27A) of the tab (26A) is sandwiched in a thickness direction between an inner surface of the open portion (16) and a front closure (30) mounted on the open portion (16). The thickness of the proximal portion (27A) of the tab (26A) of the terminal fitting (20A) is less than that of a connection portion (28A) of the tab (26A). Therefore the connection portion (28A) of the tab (26A) can have a thickness different from a predetermined thickness, provided that the proximal portion (27A) of the tab (26A) has the predetermined thickness.

Abstract: A connector has means for preventing terminal fittings from being inserted in an inverted manner, and in which nothing protrudes from outer faces of these terminal fittings. Cut-away portions 17 are formed at a ceiling side of anterior ends of left and right side plates 11B of a box-shaped member 11 of a terminal fitting 10. Protrusions 34 are formed within a cavity 24 at anterior ends of left and right wall faces thereof, in locations somewhat removed from a wall face having a lance 26 formed thereon. These protrusions 34 are capable of fitting into the cut-away portions 17. When the terminal fitting 10 is correctly inserted, the protrusions 34 fit into the cut-away portions 17, and the terminal fitting 10 is pushed into a correct position and is retained by the lance 26. When the terminal fitting 10 is inserted in an inverted manner, the anterior end of the box-shaped member 11 strikes against the protrusions 34 before the terminal fitting 10 reaches the correct position.

Abstract: The invention provides a connector with improved operability during the joining operation of electric wires and terminal fittings, and during the attachment of ferrite cores. A connector is provided with conducting members 20 capable of making contact with corresponding terminal fittings, a ferrite core 25 which is attached from the exterior to the conductive members 20, electric wire terminal fittings 27 capable of making contact with electric wires 36 and the conducting members 20, and a housing 10 which houses all of the above. The conducting members 20, to which the ferrite core 25 is attached, are formed separate from the members (the electric wire terminal fittings 27) that connect with the electric wires 36. Consequently, an automated device is able to connect the electric wire terminal fittings 27 and the electric wires 36.

Abstract: In a terminal, an resilient locking piece (24) is protruded from an upper surface of a terminal (17). The resilient locking piece (24) includes an engaging portion (25) formed at a central portion thereof, and a pair of abutting portions (26) formed on opposite sides of the engaging portion (25). The engaging portion (25) is engaged with a locking hole formed in a connector housing, while the abutting portions (26) are abutted against a surface of the connector housing which is located at a periphery of the locking-hole. Therefore, even if the terminal is pulled outwardly from the connector housing, the resilient locking piece (24) is prevented from being bent backwardly because of the presence of the abutting portions (26). That is, the terminal (17) is securely held in the connector housing without play.

A locking protrusion 21 formed on the bottom of the cover clamping portion 29 is engaged with a locking groove 22 formed in the connector housing 11. Furthermore, the height of the cover clamping portion 29 is made substantially equal to the terminal accommodating chamber 12. Hence, both the position of the front end portion of the female terminal 13 and the position of the wire clamping section 18, which is the rear end portion of the terminal, are positively regulated.

Abstract: An electrical connector having a housing with rows of offset interspaced contact receiving holes. The holes are angled along each row to facilitate interspacing of the holes with holes of adjacent rows. The electrical contacts are fabricated on a carry strip at an offset angle from the carry strip for simultaneous insertion into the angled holes of one of the rows of holes. Once the contacts are inserted into a row of the holes, the carry strip is removed. Angling the holes and interspacing them with holes in adjacent rows allows the spacing between the center paths of adjacent rows to be reduced. The offset angling of the contacts on the carry strips allows for fabrication of the contacts on the carry strip at a conventional pitch, but with nonetheless can be assembled to the housing to form a final contact spacing in the housing that is smaller than the conventional final contact spacing of prior art connectors.
