Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a cable clamp mechanism for clamping (fixing) an optical fiber cable, an electric cable or the like on a connector or the like.

"Prior Art" In the conventional cable clamp mechanism of this type, as shown in FIG. 6, a coupling hole is formed in a side surface of a connector body 11, and an end portion of the cable 12 is fitted into the coupling hole so that an adhesive agent is formed. The cable 12 was fixed to the body 11 with 13. Alternatively, as shown in FIG. 7, hold the cable 12 on the side surface of the connector body 11.
It was held down with 14, and the holding tool 14 was fixed to the body 11 with screws 15.

The conventional cable clamp mechanism takes a lot of time during cable clamping, requires several kinds of operations, and requires several operations, which has the drawback of increasing the number of steps.

[Means for Solving the Problem] According to the present invention, a square hole is formed in the side surface of the fixing portion, and a positioning tool is arranged in the square hole so that the positioning tool can be inserted and removed. A positioning hole to be inserted is formed, and a pair of holding pieces are attached to the outer surfaces of the positioning tool which face each other, and these holding pieces are opened in a state where they are removed from the square hole and are inserted into the square hole. The cable inserted into the positioning hole of the positioning tool is clamped, and the positioning tool and the fixing portion are engaged with each other by the concave-convex engaging means in a state where the clamping piece is inserted into the square hole.

"Embodiment" FIGS. 1 and 2 show an embodiment of the present invention. A square hole 22 is formed in a fixed portion, for example, a side surface of the connector body 21. A positioning tool (23) is arranged in the square hole (22) so that it can be freely moved in and out. The positioning tool 23 almost fits into the square hole 22.
A positioning hole 25 into which a cable 24 to be clamped is inserted is formed. A pair of sandwiching pieces 26, 27 are attached to the opposing outer surfaces of the positioning tool 23.
The cables 24 inserted into the positioning holes 25 of the positioning tool 23 are clamped while being opened from each other and inserted into the square holes 22. That is, the sandwiching pieces 26, 27 are the positioning tools 23.
The protrusions 26a, 27a are formed integrally with each other so as to project outward, and the protrusions 26a, 27a can be sandwiched so that the cable 24 can be eaten by the protrusions 26a, 27a. A convex portion 28 is formed on the side surface of the positioning tool 23, and the sandwiching pieces 26, 27 are formed in the square holes 22
A recess (small hole in the figure) that engages with the protrusion 28 when inserted into the inside
29 are formed on the connector body 21, and these convex portions 28 and concave portions are formed.
The positioning tool 23 does not come out of the square hole 22 due to the engagement with 29.

To clamp the cable 24 to the body 21, use the clamping pieces 26,2.
If the end of the cable 24 is inserted into the positioning hole 25 from between 7 and pushed in, the positioning tool 23 and the sandwiching pieces 26, 27 are pushed into the square hole 22, and the sandwiching pieces 26, 27 are restricted by the square hole 22. As a result, the ends thereof approach each other, and the cable 24 is sandwiched between the protrusions 26a and 27a, as shown in FIG. At this time, the convex portion 28 becomes the concave portion 29.
And the state in which this cable is clamped is held.

As can be understood from the above description, the sandwiching pieces 26, 27 are elastic pieces, and in this example, the positioning tool 23 is made of a flexible synthetic resin material.
It is a case where it is configured to be integrally connected with the inner end of.

FIGS. 4 and 5 show the case where the sandwiching pieces 26, 27 are made of metal plates, and the parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals. That is, the elastic metal plate is bent into an L-shape, and its both leg portions are sandwiching pieces 26 and 27, and the end portions of both leg portions are mutually bent inward to form protrusions 26a and 27a. Others are the same as the above-mentioned embodiment.

[Advantage of the Invention] As described above, according to the present invention, if the cable 24 is simply pushed into the positioning hole 25, the cable 24 is clamped by the clamping pieces 26, 27.
And the convex portion 28 and the concave portion 29 are engaged with each other to clamp the cable 24 to the body 21. In this way, the process of clamping work is significantly simplified.
