Definitions

  • the invention relates to a cover for a tubular terminal having an axially extending wire receiving slot.
  • United States Patent No. 3,897,128 discloses a known cover for a tubular terminal having a longitudinally extending wire receiving slot which cover comprises a tube moulded in one piece from plastics material with a closed end and an open, terminal receiving end, a wire receiving slot extending longitudinally along the plastics tube from the open end a centrally located, axially extending stuffer projecting internally from the closed end for engagement with a wire received in the slot when the cover is applied to the terminal.
  • the above United States patent specification also discloses a similar cover which has a closed end from which extends, longitudinally of the cover, a pedestal for seating a tubular electrical terminal, the cover having a wire receiving slot extending longitudinally thereof and terminating remote from the closed end in a transversely extending slot.
  • a disadvantage of the first mentioned known cover is that handling difficulties may arise particularly during initial application to the terminal with consequential risk of damage to the terminal.
  • a pair of tool receiving intersecting recesses extending transversely of the axis are formed on the exterior of the closed end and the wire receiving slot terminates remote from the closed end in a transversely extending slot.
  • the engagement of the tool in the cruciform slots ensures that correctly directed force is applied to the cover, particularly during initial application to the terminal reducing risk of damage to the terminal, by faulty application.
  • the cover 11 comprises a tube moulded in one piece from plastics material and closed at one end 12.
  • a wire receiving slot 13 extends longitudinally of the tube from an open terminal receiving end and terminates remote from the closed end 12 in a transversely extending slot 14.
  • a centrally located, axially extending, stuffer 15 projects internally from the closed end to a location adjacent the slot 14.
  • a pair of tool receiving intersecting recesses 16 extending transversely of the tube axis are formed on the exterior of the closed end and an axially extending arcuate lug 17 having the same profile as the tube is integrally formed with the closed end.
  • a terminal 19 for use with the cover is a stamped and formed metal tube adapted at one end to be mounted in a printed circuit board 23 and having a wire receiving slot 21 extending longitudinally between the ends and intersected by a transverse slot 22 which divides the terminal into two wire receiving sections, one on each side of the slot 22, which have substantially independent wire clamping characteristics as described in our British Patent No. 1,463,830 (8299).
  • an insulated wire 24 is aligned with the slot 21 ( Figure 1) and the cover is pushed onto the terminal by a tool, such as a screwdriver having a cruciform head inserted in slots 16, so that the wire is received in slot 13, engaged by the stuffer, and forced into the section of slot 21 remote from the printed circuit board.
  • a tool such as a screwdriver having a cruciform head inserted in slots 16, so that the wire is received in slot 13, engaged by the stuffer, and forced into the section of slot 21 remote from the printed circuit board.
  • the slot walls penetrate the insulation and establish electrical connection with the wire core.
  • the wire is retained above the transverse slot 22 by abutment with the corners defined between slots 21 and 22, the section of slot 21 adjacent the printed circuit board being in unexpanded condition.
  • Insertion of a second wire 25 into slot 21 pushes the first wire 24 past the slot 22 into the section of slot 21 adjacent the printed circuit board.
  • the walls of the slot 13 provide strain relief for the connection.
  • the engagement of the tool in the cruciform slots ensures that correctly directed force is applied to the cover, particularly during initial application to the terminal reducing risk of damage to the terminal by faulty application.
  • the cover may readily be removed from the terminal by gripping the lug 17 with a suitable tool such as a pair of pliers.
  • a series of covers 11 may conveniently be integrally moulded with a flexible carrier strip 27 and applied to terminals 19 unequally spaced apart on a printed circuit board reducing handling difficulties.
