An insulation-piercing connector includes a terminal block having therein a plurality of piercing terminals, and a piercing block having wire receiving apertures. When the terminal and piercing blocks are forced closer together, insulated wires of a cable received in the wire receiving apertures of the piercing block are forced into U-shaped grooves of the piercing terminals so that inner edges of the U-shaped grooves pierce into conductors of the insulated wires to electrically connect between the conductors and the piercing terminals, respectively. The piercing block is further formed at the forward ends of the wire receiving apertures with U-shaped grooves whose opposed walls form flanges which may be tapered toward each other. A distance between the opposed walls of the U-shaped grooves is less than the outer diameter of the insulated wires but more than the outer diameter of the conductors of the wires.

The cover case further has an outer sleeve which, after the inner sleeve is covered by the outer sleeve, is caulked to provide urging force onto the inner sleeve against its outer surface. Abutment edges of the two semicylinders of the inner sleeve are formed as wave-shaped edges waved in the abutment plane of the abutment edges so that the wave-shaped edges of one semicylinder are not coincident with the wave-shape edges of the other semicylinder. In another embodiment, abutment edges of the two semicylinders of the inner sleeve are provided with projecting plate members extending in the abutment plane of the abutment edges. The abutment edges of the two semicylinders are prevented from moving out of abutment with each other when the inner sleeve is subjected to compressive force when the cable is caulked.

A contact for a connector, which includes two opposed contact elements for receiving therebetween a male contact of a mating connector. Each the contact element is provided with one or more protrusions on an opposed surface for embracing the male contact. Protrusions of the two opposed contact elements extend to that portions of the opposed contact elements which are devoid of the protrusions so as to overlap each other before the male contact is inserted between the contact elements. With this arrangement, even if the male contact is very thin, pressing force required to securely pressing the male contact by the contact elements is certainly obtained. The contact and the male contact are securely contacted without any torsional force and other forces which would otherwise be caused on these contacts.

A connector connectable and disconnectable without requiring any force comprises a pivotal lever, a slide plate linearly movable in its longitudinal directions by the operation of the lever and adapted be raised and lowered in response to the linear movements, and an ON-OFF plate adapted to rise and lower in response to the rising and lowering movements of the slide plate for opening at least one pair of contacts by inserting the ON-OFF plate between the contacts in the rising movement of the ON-OFF plate and closing the pair of contacts by removing the ON-OFF plate from between the contacts in the lowering movement of the ON-OFF plate. According to the invention, the lever is made detachable from the connector to avoid the need of bulky boxes for packaging due to its elongated lever and risk of damage to the lever subjected to excess forces.

Connector connectable and disconnectable without force

This invention relates to the field of electrical connectors, and particularly concerns electrical connectors with multiple contacts requiring keying of the mating connector parts. With prior art devices, when more than one connector pair is used in a system, different connector parts must be chosen which have a different keying configuration for the key and groove. With another prior art device, which uses a single type connector part, it is necessary to sacrifice one contact position in the connectors. The present invention overcomes the deficiencies of the prior art noted above by providing a keying device which permits manufacture and production of a single type of male or female connector part and yet does not require the sacrifice of contact positions within the connector parts to effectuate the keying. The invention therefore provides an improved connector keying device for keying mating first and second connector parts to assure proper connection between the parts and to prevent connection to other connector parts of unlike keying. In accordance with the invention, there is provided a key mount affixed to the first connector part and adapted to receive a key member mounted thereto. An appropriate key member is removably attached to the key mount. A key member receiver is mounted on the second connector part and has a key member-receiving slot therein aligned with and slidingly receiving the key member when the first and second connector parts are mated.

A female electrical contact for making electrical contact with a mating male pin contact. The female contact is formed from a single piece of sheet metal and includes a pair of opposed contact leaves encased in the end of a tubular member of rectangular cross section. The tubular member has a closed end with a small aperture at its center, opening into between the two opposing contact leaves. The base for the contact leaves is U-shaped and has a pair of tabs which are bent to retain one of the rectangular faces of the tubular member in firm fixed position. The closed end may be concave to provide a camming action for the male pin to be inserted in the aperture therein. Additionally, a terminal strip portion can be provided extending from the U-shaped face to provide connection for an external conductor. Opposite sides of the tubular member can be foreshortened to bear against the two leaves to aid in biasing the leaves inwardly toward one another. If desired, the entire contact, with the exception of the terminal and closed end, can be encapsulated in a plastic cover layer by a dipping process or by insertion of a shrinkable plastic tubing over the contact. The contact can be used either singly or in a multi-contact connector block.
