Description
~ 4~ 9123 The invention relates to a cover for a tubular terminal.
According to the invention, a cover for a tubular terminal having an axially extending wire receiving slot, 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 axially along the plastlcs tube from the open end and terminating remote from the closed end in a transversely extending slot, a centrally located, axially extending stuffer projecting internally from the closed end for engagement with a wire re.ceived in the slot when the cover is applied to the terminal, a pair of tool receiving intersecting recesses extending transversely of the axis being formed on the exterior of the closed end.
A speclflc example of the invention will now be described with reference to the accompanying drawings, in which:-Figure 1 is a perspective view of a cover according to the invention aligned with a singla wire for application to a terminal;
Figure 2 is a cross-sectlonal view of the terminal and cover after application of the cover to the te~linal;
~ Figure 3 is a cross-sectional view of the : terminal and cov~r after insertion of two wires lnto j:
,, ' ~:
llllS41 the terminal; and Figure 4 is a side view of a series of covers during application to a series of terminals.
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 axially 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, ~0 axially extending, stuffer 16 projects internally from the closed end to a location adjacent the slot 14.
A pair of tool receiving intersecting recesses 16 extenaing transversely of the tube axis are formed on the exterior of the closed end and an axially lS extending arcuate lug 17 having the same profile as the tube is lntegrally 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 axially 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 indepPndent wirs clamping characteristics as descri~ed in our Great Britaln Patent Nc.

aligned with the slot 21 (Figuxe 1~ and the cover is pushed onto the terminal by a tool, such as a screwdriver having a cruciform head lnserted 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. ~uring i~sertion into the slot 21, 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 correctly directed force is applied to the cover, particularly during lnitial 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.
