The cable duct 3 located in the horizontal direction in the device 1 serves as a route for connecting the optical cable 4 to the printed board in the horizontal direction. Device 1
The cable clamp 5 provided inside has the structure shown in FIG. 2 as the first embodiment.

That is, the cable clamp 5 according to the first embodiment is a first cable clamp 51 fixed to the lower surface of the device 1 by, for example, a screw 58 and a first cable clamp 51, which can be freely removed and moved relative to the device 1. The second cable clamp 52 and the first cable clamp 5

A convex curved portion 55 that contacts the optical cable 4 and the first cable clamp 51 by a thickness corresponding to the thickness of the optical cable 4 as shown in FIG.

Then, the first cable clamp 51
Projecting claws 53 are provided on both sides of the in a tapered shape from the tip. The second cable clamp 52 is formed with a groove 57 that fits into the partition wall 56 of the first cable clamp 51, and the portion isolated by the groove 56 is fitted into a convex curved portion 55. Similarly, a concave curved portion 59 shown in FIG. 3 is formed.

The cable clamp 100 according to the second embodiment is similar to the cable clamp 5 according to the first embodiment in that the cable clamp 100 according to the second embodiment is designed to clamp an optical cable over a wide area. Conventionally, it was not possible to clamp an optical cable with a small diameter because the external force concentrates on the clamping part.
Since the cable clamp 100 according to the second embodiment has a large contact area in contact with the optical cable, an optical cable having such a small diameter can also be clamped, and the effect obtained thereby is large.

The cable clamp 5 and the second embodiment of the first embodiment
Both of the cable clamps 100 are optical cables 4
However, as a structure for clamping more optical cables, the cable clamp 22 of the third embodiment and the cable clamp 10 of the fourth embodiment are clamped.

Similar to the cable clamp 100 of the second embodiment, the cable clamp 101 of the fourth embodiment has one of the cable clamps 7 and 8 and 24 fixed instead of being movable. By doing so, it is possible to stabilize the optical cable 4 when performing work, and it is possible to collectively fix and hold a plurality of optical cables at once without impairing workability.

The cable clamp 101 of the fourth embodiment is similar to the cable clamp 100 of the second embodiment in that
Since the cable clamp 101 according to the embodiment of the present invention clamps the optical cable in a wide area, it cannot be clamped to an optical cable having a small diameter, for example, because the external force is concentrated on the clamp portion. Since the cable clamp 101 according to the fourth embodiment has a large contact area in contact with the optical cable, an optical cable having such a small diameter can be clamped.
The effect obtained thereby is great.
