Definitions

  • An electrical connector has opposing springbiased arms which are provided with means for making electrical connection with a stripped end of an insulated electrical conductor and means on one of the arms for engaging the insulation of the conductor to retain the end of the conductor in position in the connector.
  • Contact-engaging means is located on the connector for electrical engagement with a complementary contact means.
  • INIVENTOR RAYMOND FERNEX ELECTRICAL CONNECTOR This invention relates to an electrical connector for making a mechanically and electrically secure connection to an electrical wire without the aid of tooling, for example tooling for crimping a portion of the connector about the wire or for soldering the wire to the connector.
  • an electrical connector for resiliently gripping an electrical wire to make electrically conductive connection between the connector and the wire comprises a pair of superposed arms connected at one end by a bight of the connector material and each having a wiregripping member, the arms being resiliently urged towards an open position and being relatively movable towards one another from their open position to a closed position in which the wire-gripping members cooperate to grip the wire as a result of the tendency of the arms to assume their open position, the bight having an opening through which the wire can be inserted, in the open position of the arms, for engagement by the wire-gripping members, a projection on one arm, disposed between the wire-gripping members and the bight and extending towards the other arm to urge the wire against the other arm in the closed position of the arms.
  • Another object is the provision of wire-gripping members provided by opposing spring-biased arms of the connector for electrically connecting with a stripped end of the electrical conductor.
  • a further object is to provide insulation-gripping means for gripping insulation of the electrical conductor.
  • An additional object is the provision of an opening in a bight connecting the arms together and through which a stripped end of the conductor is passed.
  • FIG. I is a longitudinal cross-sectional view of an electrical connector
  • FIG. I is a perspective view of the connector when connected to an electrical wire
  • FIG. 3 is a longitudinal cross-sectional view of an electrical wall plug assembly comprising the connector, which is shown when connected to the wire, and a further and similar connector which is shown schematically;
  • FIG. 4 is a perspective view of a detail of the assembly of FIG. 3;
  • FIG. 5 is a cross-sectional view taken on the lines VV of 70 FIG. 3;
  • FIG. 6 is a plan view of a modified form of the connector.
  • FIG. 7 is a fragmentary perspective view illustrating a further modification of the connector.
  • An electrical connector 1 which has been made by stamping and forming a single piece of resilient sheet metal stock and made for example of copper, comprises arms 3 and 5 extending in superposed relationship from a bight 4. The free end of the arm 5 is fomied with a wire-gripping member in the form of a hook 6 which is directed towards the arm 3 and which is formed at its free end with a rolled receptacle 2 for an electrical plug (not shown).
  • the arm 3 is formed with wire-gripping members in the form of substantially semicircular straps 7 spaced from one another by a distance 8 slightly exceeding the width 9 of the hook 6 to enable the straps 7 to receive the hook 6 between them.
  • the arm 5 has a bent-out, trapezoidal-shaped strap 11 disposed between the hook 6 and the bight 4 and being directed towards the arm 3. Claws l2 stamped out from the floor of the strap 11 have pointed free ends directed generally towards the receptacle 2 and towards the wire-gripping members.
  • the bight 4 has an opening 13 through which the end of an insulated wire 14, from the end portion of the electrically conductive core 16 of which the insulation has been removed, can be inserted when the connector is in a relaxed condition (FIG. 1) in which the arms 3 and 5 are maintained in open spacedapart relationship under the action of the resilience of the connector material so that the hook 6 lies above (as seen in FIG. 1) the straps 7.
  • the wire end is inserted through the opening 13 so that the bared portion of the core 16 extends through the straps 7, as best seen in FIG. 5, the insulated portion of the wire end extending between the strap 11 and the arm 3.
  • the arm 5 is then pressed in the direction ofthe arrow 15 in FIG.
  • An insulating support 19 (best seen in FIG. 4) comprises a flat plate 18 having plug access holes 20 and holes 21 for receiving screws for securing the plate I8 to a wall 23 (FIG. 3).
  • a partition 22 extends at right angles from the lower (as seen in FIG. 4) face of the plate 18 and between the holes 20.
  • the plate 18 is secured to one face of a wall 23, with the partition 22 extending through a hole in the wall 23.
  • Two connectors I are positioned on the support 19 with their receptacles 2 in register with the holes 20 in the plate 18.
  • the receptacles 2 may be secured in the holes 20 or I the connectors may be secured to the partition 22, or both.
  • FIGS. 6 and 7 in which the same reference numerals indicate the same parts as in FIGS. I
  • the receptacle 2 may be replaced by a plug member 25.
  • the bight 4 may be provided with a stamped reinforcing rib 26, on either side of the v opening 13 and extending peripherally of the bight 4.
  • connector I could be used for I connection to a wholly uninsulated wire.
  • the wire core should be sufiiciently stiff to withstand the tendency of the arms 3 and 5 to move resiliently apart without bending to any substantial extent.
  • the wire core 16 is multistranded, it may be necessary to tin the strands or at least to twist the strands tightly together.
  • An advantage of the connector described above is that it enables a wire to be securely connected to a plug or a socket member without the aid of crimping or soldering tooling. Although a knife or wire stripping tool may be used to remove the insulation from the end of the core 16, the insulation, if not molded to the wire, could simply be pushed back from the end of the core 16.
  • An electrical connector for resiliently gripping an electrical wire to make electrically conductive connection between the connector and the wire, the connector comprising a pair of superposed arms, a bight of the connector material connecting said anns together at one end, a first wire-gripping means provided on one of the arms and a second wire-gripping means formed as a latch means provided on the other of the arms, the arms being resiliently urged towards an open position and being relatively movable towards one another from their open position to a closed position in which the latch means resiliently engages the wire in snap-fit and in which the latch means cooperates with the first wire-gripping means to grip the wire as a result of the tendency of the arms to assume their open position, the bight having an opening through which the wire can be inserted in the open position of the arms, the latch means and the first wire-gripping means being generally aligned with the opening in the closed position of the arms, for engagement with the wire received in the opening and a projection on one of said arms which is disposed between the wire-gripping means and the
  • a connector according to claim I in which the projection has claw means extending in the general direction of the wire-gripping means for biting into insulation on the wire in the closed position of the arms.
  • a connector according to claim 1 in which the projec' tion is fonned by a generally trapezoidal-shaped strap stamped out from one of the arms.
  • said latch means comprises a wire-engaging hook
  • said first wire-gripping means comprises a pair of straps each defining a wire-receiving aperture, the wire-receiving apertures being in axial alignment with one another and with the opening in the bight, each strap of said pair of straps being spaced from one another longitudinally of the other arm for receiving the wireengaging hook between them.
