Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method and apparatus for aligning core wires at a cable terminal.

Cables such as various power supply lines and signal lines are laid, and a large number of core wires within the cables are connected to respective main parts.

Especially when connecting to the terminal array of a terminal board placed at a predetermined interval, if this is done in a factory, it is possible to neatly arrange and connect the core wires according to the wiring jig prepared in advance. Therefore, connections can be made without errors and the appearance after wiring is also excellent.

However, when cables are laid out and connected at an installation site, etc., it is common that jigs and tools cannot be prepared in advance, and core wire connections must be made on site as appropriate. There were problems in that the appearance after the lines was poor and it took a long time to work.

(3) Purpose of the Invention In view of the above-mentioned problems, the present invention aims to provide a method and device for arranging cable core wires, which can support cable core wires in an orderly arrangement, and which can arbitrarily set intervals corresponding to the locations to be connected. shall be.

(4) Structure of the Invention The above-mentioned object is the gist of the structure of the present invention. A plurality of plate-like elastic bodies formed in a substantially inverted U shape are arranged side by side.

A screw shaft for spacing adjustment passes through the middle part of the elastic body in common, and by rotation of the screw shaft, the spacing of the elastic bodies can be changed all at once to a predetermined position, and the elastic body is folded back into a U shape. The cable core wires are respectively disposed and aligned in the gaps formed in the adjacent shaped parts (5).Embodiments of the Invention The present invention will be described below with reference to specific embodiments based on the gist of the structure.

1 to 4 show one embodiment of the present invention.

1 is a side view of the wire alignment device, FIG. 2 is a front view taken along the line A--A in FIG. 1, FIG. 3 is a perspective view, and FIG. 4 is a perspective view of an elastic body. The wire straightening device 1 includes an elastic body 3 formed in a substantially inverted U shape within a rectangular frame body 2 having side walls on three sides and one side open.
are inserted in parallel, and a holding plate 4 is similarly inserted on the open end side.

A screw shaft 6 extends vertically through the frame body 2 from the center of the two closed ends 5 of the frame body.
is screwed into the screw hole of the holding plate and protrudes for a sufficient length. The screw shaft 6 has a rotating knob recess 7 projecting from the closed end 5.

The presser plate 4 is movable in the length direction in contact with the bottom surface 8 of the frame body 2, and is fitted into guide grooves 9.9 formed at both corners of the bottom surface 8 and the side surfaces, so that it does not escape upward. It looks like this. This movement is carried out by the screw movement of the screw shaft 6.

The elastic body 3 has an inverted U-shaped bent portion that protrudes from the upper surface of the frame body 2, and as is clear from FIG. 10.10 has been drilled.

The U-shaped bent portion 11 is formed with opposing widths in between. Therefore, when they are placed side by side as shown in FIG. 1, gaps 12 are created between adjacent parts of the projecting parts from the frame body 2.

When the screw shaft 6 is rotated in the manner described above, the number of elastic bodies 3 inserted between the closed end 5 and the presser plate 4 changes the state of the compressed interval according to the movement of the presser plate 4, and each adjacent The distance between the gaps 12 between them changes.

Therefore, as shown in FIG. 1, positioning and alignment can be easily performed by making this distance P match, for example, the interval between the terminals to which the core wires are to be connected, and arranging the core wires 15 respectively.

FIG. 3 shows this state more easily.The end of the cable 14 is appropriately treated, the core wire 15 is drawn out, and the core wires 15 are drawn out parallel to the frame 2, and their mutual positions are determined, and the core wires 15 are connected in order. It is successively bent toward the wire straightening device side and inserted and supported within the gap 12.

When all the core wires are arranged and aligned in this way, core wire 1
The cables 14 are cut to a predetermined length with the same length, and their coatings are removed to make them connectable to terminals, and the cables 14 are removed from the wire straightening device 1 and connected to terminals (not shown).

The above means that the opposing width of the U-shape of the elastic body 3 is formed wider than the maximum interval between the terminals so that it can cope with compression return;
Furthermore, it goes without saying that the adjacent gap 12 is determined so that the core wire can be inserted and held even if the gap changes.

Furthermore, the elastic bodies 3 can be replaced with ones of different opposing widths, and the number of the elastic bodies 3 can be arbitrarily determined. If the hole 10 is made notched as shown by the dotted line (FIG. 4) to accommodate this purpose, the screw shaft 6 can be loosened relative to the presser plate 4 without being removed.

Different embodiments of the invention are shown in FIGS. 5 and 6.

In the side view of FIG. 5, the bottom plate 8 on the open end side of the frame body 2 is made to protrude 16 in a dovetail shape, and a separate frame body is formed, which has only the side surfaces and both ends are open, and the side plates are not shown. There is no bottom plate 17
(Only shown in FIG. 6) It is provided with a dovetail groove 18 which can be fitted and connected to the dovetail projection 16.

Therefore, if you connect this extension frame, you can make an even longer frame, so if you replace the screw shaft with one of the corresponding length and add an elastic body, you can align even more core wires. I can do it. FIG. 7 shows a different embodiment of the elastic body, in which the bent shape of the U-shape forms a triangular chevron 19, and the spacing 20 between the adjacent adjacent ones is V.
It is the shape.

Because of this, almost any core wire can be held regardless of its thickness.

(6) Effects of the Invention As described above, according to the present invention, the core wires are arranged and aligned in the gaps where a large number of elastic bodies are arranged side by side, so it is extremely easy to work with, and as a portable type, it can be easily installed on site. Not only is it extremely convenient for use in other applications, but the spacing between core wires can also be arbitrarily adjusted and set, which is a method and device that has never existed before, and its effects are remarkable.
