【Example】
An embodiment of a wiring fastener according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
The wiring fastener 1 includes two main bodies 4 and 4 including a support member 2 that supports an optical fiber cord (not shown), and a pressing member 3 that presses the optical fiber cord against the support member 2. It comprises a connecting member 5 for connecting the main bodies 4 and 4.
[0010]
The support member 2 of the main body 4 is formed with leg portions 2b, 2b, 2b, 2b by bending the four corners of the flat plate portion 2a, and a mounting screw 6 is inserted in the vicinity of one end edge in the longitudinal direction of the flat plate portion 2a. A plurality of screw holes 2c, 2c,... Are formed at equal intervals. As shown in FIG. 3, the screw hole 2c is for fixing the tension member 7 of the optical fiber cord, and the square screw washer 8 is inserted into the attachment screw 6, and the attachment screw 6 is screwed into the screw hole 2c. Thus, the tension member 7 is nipped and fixed by the square washer 8 and the flat plate portion 2a. Protrusions 2d and 2d are formed on both sides of each screw hole 2c, and rotation of the square washer 8 is prevented by the protrusions 2d and 2d. Also, a cushioning soft material 9 is affixed in the vicinity of the other side end in the longitudinal direction of the flat plate portion 2a.
[0011]
The pressing member 3 of the main body 4 has leg portions 3b, 3b, 3b, 3b formed by bending four corners of the flat plate portion 3a. The optical fiber cord is juxtaposed above the soft material 9 of the support member 2, and the optical fiber cord is sandwiched by the flat plate portion 3a with the leg portion 3b of the pressing member 3 facing upward. Screw insertion holes 3c, 3c, 2e, and 2e through which the fixing screw 10 is inserted are formed in the vicinity of both ends of the pressing member 3 and the supporting member 2, and the screw insertion hole 3c of the pressing member 3 and the supporting member are inserted. The fixing screw 10 is inserted into the second screw insertion hole 2e and fixed by screwing.
[0012]
The connecting member 5 is composed of parallel fixing pieces 5a and 5b for fixing the two main bodies 4 and 4, and a hanging piece 5c connecting the fixing pieces 5a and 5b. The width dimension of the lower fixed piece 5b is larger than the width dimension of the main body 4, and the leg portions 2b, 2b, 2b, 2b of the main body 4 are placed on the upper surface of the fixed piece 5b. Screw insertion holes 2f, 2f, 5d, and 5d through which the connection screws 11 are inserted are formed in the vicinity of both ends of the support member 2 of the main body 4 and the lower fixed piece 5b of the connection member 5, and are supported. The connecting screw 11 is inserted into the screw insertion holes 2f, 2f of the member 2 and the screw insertion holes 5d, 5d of the lower fixing piece 5b, and both are fixed and screwed to the optical termination box 12 at the same time.
[0013]
The width dimension of the upper fixed piece 5a is smaller than the width dimension of the main body 4, and the flat plate portion 2a of the support member 2 of the main body 4 is placed on the upper surface of the fixed piece 5a. At this time, the legs 2b, 2b, 2b, 2b of the support member 2a are brought into contact with the end of the fixed piece 5a for positioning. Screw insertion holes 2f, 2f, 5d, and 5d through which the connection screws 11 are inserted are formed in the vicinity of both ends of the support member 2 of the main body 4 and the upper fixed piece 5a of the connection member 5, and the support member The connection screw 11 is inserted into the screw insertion holes 2f and 2f of the second screw and the screw insertion holes 5d and 5d of the upper fixing piece 5a and fixed by screwing. The upper fixing piece 5a and the lower fixing piece 5b are arranged so that the upper fixing piece 5a and the lower fixing piece 5b do not overlap in the width direction so that the optical fiber cord can be fixed.
[0014]
The hanging piece 5c of the connecting member 5 is formed with a through hole 5e through which the optical fiber cord is inserted, and the optical fiber cord is inserted into the through hole 5e and fixed to the main body 4 fixed to the lower stage. The vertical piece 5c prevents the main body 4 fixed on the upper stage and the main body 4 fixed on the lower stage from overlapping each other in the height direction.
[0015]
In this embodiment, the tension member 7 of the optical fiber cord can be fixed to the support member 2 of the main body 4, but the support member 22 of the main body 24 may only fix the optical fiber cord as shown in FIG. .
[0016]
In this embodiment, the connecting member is formed in two stages so that two main bodies can be fixed. However, there is no problem even if the connecting member is formed in a plurality of stages, and can be changed as appropriate without departing from the gist of the present invention. .
[0017]
【The invention's effect】
As described above, the wiring fastener according to the present invention is provided in the optical termination box used for connecting the optical fiber, and in the wiring fastener for fixing the optical fiber cord, the support member for supporting the optical fiber cord, and the support member By connecting multiple main bodies consisting of pressing members for pressing optical fiber cords to each other by shifting them in the height direction with connecting members, it is easy to add more main bodies even when a large number of optical fiber cords must be fixed. This has an excellent effect that it can be fixed in a small space.
[0018]
The connecting member is composed of a plurality of parallel fixing pieces for fixing the main body and a hanging piece for connecting the fixing pieces. By forming a through hole for inserting the optical fiber cord into the hanging piece, the connecting member is simplified. There is an excellent effect that a plurality of main bodies can be connected with a simple structure.
