Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a processing apparatus for a C-long ribbon cable, in which a single connection terminal is attached to the end of a ribbon cable.

"Prior Art and its Problems" As shown in FIG. 10, the ribbon cable 11 is made up of a plurality of electric wires 12 connected in parallel to each other in a flat tf configuration. When processing the ribbon cable 11, the ends 12a of each cable 812 are separated from each other. Roughly separated ends 1 of electric wires 12
For example, a pressure contact terminal 13 is attached to 2a. The pressure welding terminal 13 has a mounting groove 14 into which the end 12a of each electric wire 12 is fitted, and the end 12a is fitted with a pressure welding machine (not shown).
%Installation is done by driving the pressure contact terminal 1 into the groove 14.
3 or more can be installed. In this case, each electric M!
The end portion 12a of 12 is separated by a predetermined distance 11i5! Is it necessary to hold them in a state where they are expanded parallel to each other? Conventionally, as means for arranging the ends 12a of the wires 12 of the ribbon cable 11 as described above, a plurality of parallel juts or the like have been used at predetermined intervals. That is,
A bottle is inserted between each end 12a, and the ends 12a are expanded.

However, in the above-mentioned ribbon cable processing device, when the end portions 12a of the electric wires 12 are expanded by inserting the bin, the ends 12a spread radially toward the tip, and each end portion 12a When installing the pressure-pneumatic terminal 13, the position of the groove 14 did not match accurately, which often resulted in installation errors.

``Object of the Invention'' The object of the present invention is to spread the M-shaped ends of the ribbon cable parallel to each other and align them so that each end can be accurately driven into the groove for installing the pressure contact terminal. We provide processing bags for ribbon cables.

``Structure of the Invention'' The ribbon cable processing apparatus of the present invention includes a clamp that holds the end of the ribbon cable, and an alignment means that spreads the separated ends of the ribbon cable parallel to each other with a predetermined distance of 111 il. and a pressure welding machine that drives the end of the ribbon cable into the pressure contact terminal to attach the pressure contact terminal, and the alignment means includes a plurality of comb-like shapes that extend radially from the end edge and are parallel to each other. has a slit,
Further, it is characterized by an alignment blade that is formed to become thicker as it goes away from the edge.

Therefore, by pushing the alignment blade into the end of the ribbon cable, each electric wire of the 1-nopon cable is inserted into the slit of the open alignment blade, and the wires are aligned in parallel with each other with their diameters expanded. In this case, since the slits of the alignment blade are formed so as to extend radially from the edge and become parallel to each other, each electric wire can be inserted into the slit easily. In addition, the alignment blade becomes thicker as it goes away from the edge, so when each wire is pushed deep into the slit, it is held at a predetermined length by the comb-shaped portion of the alignment blade. Therefore, the tips of each electric wire can be aligned in parallel. Then, in this state, while holding the end of the ribbon cable with a clamp, the end of each electric wire is driven into the insulation displacement terminal using a pressure welding machine, thereby making it possible to accurately attach the insulation displacement terminal. Therefore, the occurrence of defective products can be reduced and the yield can be improved.
