Claims
- 1. A connector for a cable having at least one insulated conductor wherein electrical connection with said conductor is made within the housing by axially piercing the end face of the conductor, said connector comprising:
- a insulation housing with said insulated conductor inserted through an aperture in a sidewall of the housing,
- a pierce contact element inserted through an opposite sidewall of housing, said contact element including a base from which projects a pointed tang and two arms, one arm on either side of the pointed tang, both arms being provided with teeth along their inside edges, said inside edges running parallel to from the center line of the pointed tang and at a distance therefrom which is adjusted to the dimensions of the housing whereby when the pierce contact element is inserted into the housing, the pointed tang pierces axially into the end face of the conductor and the teeth of the arms penetrate into and grip portions of the connector housing surrounding the conductor which has been pierced axially by the tang, said contact element further including a contact crown projecting from said base, said contact crown adapted to electrically contact a contact strip or contacting wire in a matching connector.
- 2. A connector according to claim 1 wherein the contact crown has a contact surface along which said contact strip or contact wire of the matching connector contacts said crown during the mating of the connector with the matching connector, said contact surface being curved according to a radius of curvature which is at least several times larger than half the width of the contact crown.
- 3. A connector for a cable having a plurality of insulated conductors, each of said conductors being inserted within a housing of the connector and therein pierced and clamped by a pierce contact element so as to make electrical connection therewith, each said pierce contact element comprising
- a substantially flat, conductive body having at least one pointed part intended for piercing into said insulated conductor, and
- a contact crown which in the assembled state projects outside the connector housing and has a contact surface which is adapted to electrically contact a contact strip or contact wire in a mating connector, said contact strip or contact wire forming an angle with the plug-in direction of the connector into the mating connector, said angle changing as a result of the movement of the point of contact along the contact surface of the crown during insertion of the connector into the mating connector, the contact surface of said contact crown being curved according to a radius of curvature which is at least several times larger than half the width of the contact crown, whereby the contact point between said contact strip or contact wire of the mating connector and the curved contact surface of said contact crown moves along said curved contact surface during insertion of the connector into the mating connector a distance which is almost the same as the width as the contact crown, thereby minimizing the wear along the curved contact surface.
- 4. A connector according to claim 3 wherein the pointed part of said pierce contact element pierces laterally through an insulation jacket surrounding each conductor.
- 5. A connector according to claim 3 wherein the pointed part of said pierce contact element pierces axially into the end face of the conductor.
- 6. A connector according to claim 5 wherein said pierce contact element further comprises a base from which projects a pointed tang and two arms, one arm on either side of the pointed tang, both arms being provided with teeth along their inside edges, said inside edges running parallel to from the center one of the pointed tang and at a distance therefrom which is adjusted to the dimensions of the housing whereby when the pierce contact element is inserted into the housing, the pointed tang pierces axially into the end face of the conductor and the teeth of the arms penetrate into and grip lateral portions of the insulation surrounding the conductor which has been pierced axially by the tang.
