Definitions

  • This invention relates to a terminal assembly comprising a terminal conductor, a washer and a tightening screw, and which is especially useful for connecting a lead wire to electrical equipment.
  • a typical terminal assembly includes a terminal conductor, which is generally flat, to be connected to the electric equipment, a washer adapted to overlie a lead wire conductor to be secured to the terminal conductor, and a screw for tightening the assembly.
  • the washer has a relatively large hole
  • the terminal conductor has a threaded hole
  • the washer is placed on the terminal conductor
  • the lead wire is placed between the terminal conductor and the washer
  • the screw is inserted through the washer and engages the threaded hole in the terminal conductor.
  • an object of this invention is to provide a novel and improved terminal assembly which does not involve troublesome hand-work to connect a lead wire to the terminal assembly.
  • the terminal assembly includes a terminal conductor, a washer and a tightening screw, but the washer has a threaded hole and the terminal conductor has a large hole.
  • the screw is inserted through the terminal conductor to the washer.
  • FIG. 1 is a perspective view representing a typical example of the terminal assembly according to the prior art.
  • FIG. 2 is a perspective view representing a typical embodiment of the terminal assembly according to this invention.
  • the terminal assembly in HO. 1 the terminal assembly according to prior art consists of a flat terminal conductor 1, a washer member 3 having a U-shaped cross-section which can engage with the terminal conductor 1, and a screw 5; and the terminal conductor 1 has a threaded hole 2 to engage the screw 5, and the washer member 3 has a large hole 4 to clear the screw.
  • the screw 5 is loosened, the washer member 3 is held up by hand or the like, the lead wire 6 is inserted in the gap between the terminal conductor 1 and the washer member 3 and then the screw is again tightened.
  • a washer member 3 is disposed on the opposite side with respect to FIG. 1 and the washer member 3 has a threaded hole 4, while the terminal conductor 1 has a clearance hole 2'.
  • the washer member 3 is driven downwardly and the gap between the terminal conductor 1 and the washer member 3 is positively opened. Therefore, by inserting the lead wire 6 between this gap and again tightening the screw, the connection is completed.
  • the distance D between the end of the washer 3 and the screw hole 4' is greater than the distance d between the end of the terminal conductor 1 and the clearance hole 2', insertion of the lead wire 6 can be further facilitated.
  • the improved terminal assembly prevents troublesome and unpleasant supplemental work and improves work efficiency remarkably.
  • a terminal assembly comprising a rectangular terminal conductor having an opening therein spaced from an end thereof, a threaded screw slidably engaging said opening, a channel member having a transverse member and a pair of upwardly extending legs, said legs being spaced apart a distance slightly greater than the width of said rectangular member and said transverse member lying beneath said conductor with the legs slidably engaging the sides of said conductor, and a threaded hole in said transverse member for threadably engaging said screw, said threaded hole being spaced inwardly from the end of said channel member a distance greater than the distance between the opening in said conductor and the adjoining end thereof so that said channel member extends slightly beyond the end of said conductor.
