Claims

[Scope of utility model registration request]

(1) Attach the holder 7 that holds the light emitting element 21 and the light receiving element 22 to the window 4 of the housing 1, and
A hole 9 through which the end of the optical fiber 25 is inserted is provided at the outer end of the holder, and a sliding portion extends from the outside along the axis of the hole 9 and divides the hole into two. 10, and by bending a plate-like body between the sliding parts, a holding part 39 that engages with the inner wall of each hole 9 and clamps the optical fiber 25 is formed so that its concave surfaces face each other. A pair of retaining plates 37 are provided, and the holder 7 is provided with a tightening screw 15 passing through the holder and the retaining plate 37 in a direction intersecting the axis of the hole 9. By inserting the end of the optical fiber 25 between the holes 39 and 39 and tightening the tightening screw 15, the optical fiber 25 is attached to the holder 7.
An optical fiber set photoelectric switch in which the optical fibers are fixed to the light emitting element 21 and the light receiving element 22 and are optically connected to the light emitting element 21 and the light receiving element 22.

(2) A utility model in which, on one side of the holding piece 11 formed by the sliding portion 10 of the holder 7, a thin wall portion 13 parallel to the sliding portion 10 is formed in a portion close to the holder 7 side. An optical fiber complete photoelectric switch according to claim 1.
