Definitions

  • FIG. 2 shows a conventional connector for the terminal block of FIG. 1.
  • the drawing depicts the housing of a connector 13 inside its elongated pole 11 (shown in phantom lines) of the mass block.
  • Two wires to be electrically connected for either power or signal relay purposes can be inserted each into the two opposite openings of a connector 13.
  • a screw 15 is provided near each end of the connector 13 that can be screwed into its corresponding screw hole 131, which is opened through the entire thickness of the wall of the connector's generally cylindrical body and allows the passing through of its corresponding screw 15.
  • the screw 15 sinks into a screw well 16 provided on the pole 11 of the mass block.
  • An electrically conductive resilient cover plate 14 is provided ahead of the opening of the screw hole 131 along the screw-in direction of each of the screws 15.
  • the screw 15 can be driven inward so as to push the cover plate 14 onto the wire end.
  • the screw-in of the screw 15 allows the wire end to be squeezed between the plate 14 and the cylindrical housing wall of the connector 13 opposite the screw hole 131. With sufficient screwing force, the connector 13 allows to both prevent the break off of the wire and ensure good electrical contact between the wire and the electrically conductive housing of the connector 13.
  • the present invention achieves the above by providing a connector for a terminal block for adjoining a pair of wires for providing electrical conduction between said wires, said connector comprising a cylindrical body having one screw hole near each end of said body and a wire end plate formed internally to and at substantially the longitudinal center of said body for limiting insertion of said wires; and a conduction plate inserted into the hollow space of said cylindrical body, said conduction plate having a length substantially the same as that of said cylindrical body along the longitudinal direction thereof; wherein said conduction plate having a concaved surface conforming to the generally spherical cross section of said wires for partially enclosing said wires when inserted for said adjoining; said concaved surface providing low electrical resistance between said adjoining wires when two screws mating with said screw holes are installed and each driven firmly onto the corresponding one of said adjoining wires thereby squeezing said wires firmly onto said conduction plate.
  • the depicted preferred embodiment of the wire adjoining connector 23 of the present invention as illustrated herein has an end shape that resembles the capital English letter "D."
  • the two screw holes 231 for the wire-securing screws are formed on the flat portion of the cylindrical body of the connector 23, as is see in FIG. 5.
  • the flat portion of the cylindrical body of the connector 23 is where the two ends of the roll-formed sheet material meet.
  • the generally cylindrical-shaped configuration of the connector 23 of FIG. 5 encloses a hollow internal space, in which a conduction plate 25 can be inserted.
  • the conduction plate 25 is preferably made of a commercially optimized electrical conduction material, brass with sufficient copper content for example.
  • the conduction plate 25 has an end shape in conformity with the curved segment of the letter "D" end shape of the connector 23 opposite to the straight vertical segment thereof as it is inserted into the hollow space of the connector 23 directly next to that curved wall.
  • the conduction plate 25 should be fixed to its correspondingly shaped inner sidewall of the connector 23 via, for example, spot welding that allows best possible electrical conduction between the two.
  • the conduction plate 25 has a length along the longitudinal direction of the connector 23 that is substantially equal to the length of the connector in which it is inserted.
  • FIG. 5 There is one single punching through the connector body sidewall is shown in FIG. 5, however, two punchings each with smaller bent wall than in the case of one single bent plate are also applicable.
  • the two smaller bent plates formed substantially at the middle along the longitudinal length of the connector body can be aligned opposite to each other to make up an equivalent single wire end stopping plate 232.
  • the screw-in of the wire-securing screw 24 allows the wire end to be tightly squeezed between the screw tip (or the resilient cover plate should one be used) and the concaved inner surface of the conduction plate 25.
  • the wire adjoining connector 23 of the present invention allows to both prevent the break off of the wires and ensure good electrical contact between the two adjoined wires.
  • the electrical conduction between any pair of adjoined wires is significantly better than that is provided by conventional terminal blocks. This improved electrical conduction is due to the presence of the contoured conduction plate in the connector body.
  • the inwardly curved surface of the conduction plate conforms to and perfectly partially encloses the generally spherical cross section of any wire to be adjoined.
  • the connector for the terminal block in accordance with the teaching of the present invention can also enjoy the benefit of cost reduction.
  • the connector body can be made of structurally strong and yet cheap metallic or alloy material.
  • plated steel sheets which are much cheaper than brass, can be used to make the connector body.
  • Steel sheet provides good structural strength for the connector while is also electrically conductive. Therefore, a wire adjoining connector in accordance with the teaching of the present invention having a steel body and an inner lining brass conduction plate is capable of achieving optimized price-performance characteristics.
