Abstract
Apparatus for connecting by pressure a plurality of insulated conductors of a multiconductor cable to a plurality of contact terminals spaced at equal intervals along a terminal strip, which includes; (a) a feed rail for guiding the terminal strip; (b) a sprocket wheel engageable with apertures spaced on the terminal strip for guiding it along the feed rail; (c) a step motor for driving the sprocket wheel; (d) a cable support for moving the cable toward the terminal strip on the feed rail to insert the front ends of the cable into the contact terminals; and (e) a device for simultaneously pressing a plurality of the contact terminals into a plurality of insulated conductors of the cable.
Claims11
Apparatus for connecting by pressure a plurality of insulated conductors of a multiconductor flat cable to a plurality of contact terminals attached at an end to a terminal strip having a plurality of guide apertures spaced at equal intervals along said terminal strip, which includes:
- a feed rail with a guiding groove along which said terminal strip is fed;
- a sprocket wheel for advancing said terminal strip by engaging said guide apertures;
- a step motor for intermittently rotating said sprocket wheel;
- a pair of upper and lower punches, with said lower punch provided on level with said guiding groove;
- a generally rectangular cable support station secured at substantially right angles to a side of said feed rail to advance said multiconductor flat cable toward said contact terminals placed on said lower punch for insertion of respective insulated conductors of said multiconductor flat cable into said contact terminals;
- and
- press means for moving said upper punch toward said lower punch to press said contact terminals into said insulated conductors of said multiconductor flat cable for connection by pressure, wherein said cable support station comprises:
- a base plate with a support groove;
- a cable support slidable along said support groove;
- a cable guide provided on said slidable cable support against which a side of said multiconductor flat cable is to be abutted for positioning;
- a cable holder for holding said multiconductor flat cable in place along said cable guide on said slidable cable support;
- a cable stopper for positioning respective insulated conductors of said multiconductor flat cable held on said slidable cable support with said cable holder along said cable guide;
- and
- lowering means for lowering said cable stopper below a horizontal plane in which said slidable cable support is movable.
Apparatus for simultaneously terminating a plurality of insulated conductors of a multiconductor cable to a plurality of contact terminals connected to a terminal strip having a plurality of guide apertures at equal intervals, which comprises:
- press means in which said contact terminals are pressed into said insulated conductors for connection by pressure;
- feeding means for intermittently feeding said terminal strip into said press means;
- said feeding means including:
- a feed rail extending laterally to said press means;
- a sprocket wheel pivoted to an end portion of said feed rail opposite to said press means for engagement with said guide apertures to feed said terminal strip into said press means;
- a step motor for intermittently rotating said sprocket wheel;
- and
- control means responsive to an input signal to control an angle of rotation of said step motor such that a predetermined number of said contact terminals are fed into said press means with a difference by one pitch of said insulated conductors from a previous amount of feed, whereby said insulated conductors are terminated to every other said contact terminals spaced along said terminal strip at intervals twice as large as those of said insulated conductors;
- and
- alignment means for holding said multiconductor cable in alignment with said contact terminals in said press means.
Apparatus for simultaneously terminating a plurality of insulated conductors of a multiconductor cable to a plurality of contact terminals connected to a terminal strip having a plurality of guide apertures at equal intervals which comprises:
- press means in which said contact terminals are pressed into said insulated conductors for connection by pressure;
- feeding means for intermittently feeding said terminal strip into said press means;
- and
- alignment means for holding said multiconductor cable in alignment with said contact terminals in said press means, said alignment means including:
- a cable support with a generally rectangular shape which is movable on said alignment means in a normal direction perpendicular to a longitudinal axis of said feeding means and has a cable guide along an edge in said normal direction;
- a cable holder with a substantially L-shaped form, with a leg hinged to the edge opposite to said edge for holding said multiconductor cable with a side abutting said cable guide with a pressure applied to said multiconductor cable in a vertical direction perpendicular to a plane of said cable support;
- and
- a cable stopper vertically movable in front of said cable holder between upper and lower positions;
- at said upper position, ends of said insulated conductors are abutted against a flat face of said cable stopper for positioning and at said lower position, said insulated conductors are advanced into said press means for effecting connection by pressure.
