Description

[Detailed Description of the Invention] The present invention relates to a cord terminal processing structure, and its object is to easily and reliably attach the hook sealing to the cap.

Fig. 1 shows a conventional example, in which a pair of electric wires 2, 2 covered with a thin insulation coating 1 is surrounded by an intervening thread 3, and the outer periphery is wrapped with a braided outer sheath 4. This is the part that attaches the seal to the cap.

The outer sheath 4 near the tip of the round cord 5 is peeled off and cut, the exposed intervening thread 3 is loosened to expose the electric wire 2, and the outer sheath 4 is removed.
A ring-shaped body 6 is inserted around the outer periphery of the tip of the ring-shaped body 6, the intervening thread 3 is folded back to cover the ring-shaped body 6, the tip of the intervening thread 3 is tied with a string 7, and the ring-shaped body 6 is wrapped inside the intervening thread 3 and attached.

The end portion of the cord formed in this way, which has a larger diameter than the outer circumference, is inserted through and locked into the hole of the cap of the hook ceiling (not shown), and receives the load of the lighting fixture suspended from the other end of the cord.

However, in the above-mentioned conventional example, it takes time and effort to loosen the outer skin 4 and the intervening thread 3 and tie them with the strings 7, and the way the strings 7 are tied may cause a difference in the force applied to the load.

The present invention has been devised in view of the above points, and will be explained below based on the drawings.

FIGS. 2 to 5 show an embodiment of the present invention, and show a cord terminal processing structure using the terminal processing tool 8 shown in FIG.

The terminal processing tool 8 is formed of a molded product and consists of two divided bodies 10.10 connected by a thin hinge 9, and each divided body 10.10 is integrated by engaging and disengaging the claw 11 and the window 12. combine or separate.

A cord insertion hole 20 is formed in the center of each divided body 10, 10 in a substantially semi-cylindrical shape so as to span both, and a plurality of protrusions 1 are formed on the inner periphery of the cord insertion hole 20 along the circumferential direction.
3 is formed.

Further, each divided body 10.10 is provided with a wire holding groove 14 connected from the upper surface to the outer surface and having a narrow entrance.

The cord is a round cord 5 similar to that described above in the conventional example, and the terminal processing tool 8 is attached as shown in FIG. 3 as follows.

First, leaving an appropriate length from the tip of the cord 5, sandwich the divided bodies 10, 10 separated by the hinge 9 from the sides, and combine each divided body integrally by engaging the claw 11 and the window 12. The cord 5 is held in the cord insertion hole 20.

At this time, the protruding strip 13 formed on the inner periphery of the cord insertion hole 20 is pushed into the outer skin 4 of the cord, and the cord 5 is securely held.

After that, the outer skin 4 and the intervening thread 3 of the portion protruding from the terminal processing tool 8 are removed to expose the electric wires 2, and each electric wire 2 is bent and press-fitted into the electric wire holding groove 14 on the surface and outer surface. They are led out to the sides in opposite directions.

A terminal 15 is caulked to the tip of the conductive wire 2, and the terminal 15 is connected and fixed to the stopper blade 17 of the hook sealing cap 16.

The cord 5 is inserted into a hole 18 provided in the center of the cap 16, and a cylindrical portion 19 protruding from the lower surface of the terminal processing tool 8 surrounding the cord is also inserted into the hole 18.

The outer shape of the terminal processing tool 8 is approximately the same as the internal recess of the cap 16, and is housed in the recess to prevent the cord 5 and the cap 16 from rotating.

Note that the outer sheath 4 and intervening yarn of the cord 5 protruding from the terminal processing tool 8 are loosened, and the electric wire 2 is bent and press-fitted into the wire holding groove 14 on the surface and outer surface. 3, it is possible to cut along the upper surface of the terminal processing tool 8, so that the outer sheath 4 and the intervening thread 3 can be reliably and easily removed without damaging the electric wire 2, and the finish is good.

As described above, in the present invention, the end treatment tool is divided into two parts, and a cord insertion hole is formed that passes through the cord in a straight line. It is easy to attach the terminal processing tool to the cord, and there is no need to pre-process the cord for attaching the terminal processing tool, and the wire is bent and fitted into the wire holding groove, so the cord can be held more securely. I can do it.
