Next, by operating the closing means, the top edge 102 of the strip 101 is deformed from its original shape so as to close the gap in the opening on the side of the top edge 102 of the strip 101 . Specifically, by pulling and tying both ends of the string-like member 106 extending from the narrowed portion 105, the opening on the side of the top edge portion 102 can be narrowed so as to reduce the diameter. At this time, as shown in FIG. 9(c), the inner surface of the top edge portion 102 abuts against the outer periphery of the wiring member 15 and the gap is relatively smaller than the initial gap. , the belt-like body 101 does not intervene and a gap remains. Then, as shown in FIG. 9(c), a pair of through holes 107 are arranged to face each other between the wiring members 15 adjacent to each other. At this time, since the belt-like body 101 is a flexible sheet, each through-hole 107 can be moved to a predetermined position by shifting the top edge 102 in the circumferential direction. After inserting the tip of the band portion 109a of the binding member 109 into the through holes 107, 107 facing each other in the width direction, the tip of the band portion 109a is inserted into the locking hole of the lock portion 109b so as to form a ring with the band portion 109a. The opposing top edges 102 can be bound together by cinching them together. That is, the binding member 109 can be used to close the gap between the adjacent wiring members 15 . This step is sequentially performed for a plurality of opposing through holes 107,107. As a result, each wiring member 15 can be surrounded by the top edge portion 102 of the band-shaped body 101, and the installation structure 10 with almost no gap can be constructed.

FIG. 10 shows another usage example of the outlet cover 100 of this embodiment. As in the installation structure 10' shown in FIG. 10, the magnetic attachment part 104 is magnetically attached to the inner surface of the switchboard 11, the belt-shaped body 101 is pulled out from the wiring outlet 12, and the closing means is arranged outside the switchboard 11. may be

Further, in the above embodiment, each binding member 109 is inserted through the pair of through holes 107, 107 between the wiring members 15, respectively. It is not limited to the above usage examples. For example, as in the installation structure 10″ shown in FIG. 11, one binding member 109 is passed through four through holes 107 (two pairs of opposing through holes 107), and the binding member 109 surrounds the wiring member 15. 109. In this case, two binding members 109 can be inserted through one through-hole 107. Although not shown, the side walls on the long side of the band-shaped body 101 are threaded. The hole 107 and the through hole 107 in the side wall on the short side may be arranged to face each other, and the binding member 109 may be passed obliquely.

Furthermore, as another example of use, as shown in FIG. 12, a cushion material 110 may be selectively arranged so as to surround the wiring material 15 in the opening on the side of the top edge portion 102 . In other words, the outlet cover of the present invention may comprise a cushioning material arranged inside the opening on the top edge side of the strip. As in the installation structure 10'''' shown in FIG. The gap between the inner peripheral surface of 101 and the outer periphery of wiring member 15 is effectively filled. However, FIG. 12 is only an example, and the binding member 109 may be passed through the cushioning material 110 and used to further bind the opening of the strip 101 on the side of the top edge 102 with the binding member 109 . That is, since the cushioning material 110 is interposed between the inner peripheral surface of the band-shaped body 101 and the outer periphery of the wiring material 15, the cushioning material is compressed when the binding member 109 binds, and the direct load ( In addition, the cushion material can be deformed so as to follow the shape of the wiring material 15 and the inner peripheral surface of the belt-like body 101, thereby closing the gap more effectively. This effectively prevents dust and insects from entering inside the switchboard 11 . The cushioning material may be attached to the inner surface of the top edge of the strip, or may be supported only in an elastically compressed state.

As a further example of use, when the wiring outlet of a switchboard is large enough to be enclosed by one outlet cover 100, a plurality of outlet covers 100 may be connected in the circumferential direction and used. FIG. 13 shows an example in which two outlet coverings 100, 100 are connected and used. As shown in FIG. 13(a), the hook-and-loop fastener 108a on the surface side (the right end in FIG. 3(a)) of the connection maintaining means 108 of one outlet cover 100 serves to maintain the connection of the other outlet cover 100. As shown in FIG. By bonding to the hook-and-loop fastener 108a on the back side of the means 108 (the left end in FIG. 3(b)), a tubular body having a larger diameter opening is formed, and the wiring outlet 12 having a wider area is formed. besieging. Then, by pulling the string-like members 106, 106 so as to contract the top edges 102, 102 of the outlet coverings 100, 100, a larger diameter opening can be squeezed. Furthermore, by inserting the binding member 109 into the through holes 107, 107 positioned facing each other between the eight wiring members 15, as shown in FIG. 10''' can be constructed. That is, the outlet cover 100 of the present embodiment can be used in combination with two or more (same) outlet covers 100 to support electrical equipment housings having wiring outlets of various sizes. is possible.

Hereinafter, the effects of the outlet cover 100 of one embodiment according to the present invention will be described.

According to the outlet cover 100 of the present embodiment, the magnetically attached portion 104 provided on the belt-shaped body 101 is attached to the magnetic outlet surrounding portion 13 provided around the wiring outlet 12 of the switchboard 11 . Magnetic attachment makes it possible to easily attach the outlet cover 100 to the switchboard 11 while surrounding the wiring outlet 12 in the circumferential direction. Moreover, since the connection between the outlet cover 100 and the switchboard 11 is based on magnetic attachment, the two can be easily separated by pulling the outlet cover 100 away from the switchboard 11 . Further, the band-shaped body 101 can be developed into a planar shape, and can be assembled into a cylindrical shape by connecting both ends of the expanded band-shaped body 101 with the connection maintaining means 108 . As a result, the wiring member 15 is surrounded while the wiring member 15 is pulled out from the wiring outlet 12 (in other words, without removing the wiring member 15 from the switchboard 11) in the work of installing the outlet cover 100. It is possible to attach the outlet cover 100 to the switchboard 11 by transforming the belt-shaped body 101 from the flat unfolded form to the cylindrical assembled form. Also, in the operation of removing the outlet cover 100, the wiring member 15 is surrounded while the wiring member 15 is pulled out from the wiring outlet 12 (in other words, without removing the wiring member 15 from the switchboard 11). The outlet cover 100 can be removed from the switchboard 11 by transforming the belt-shaped body 101 from the assembled form to the deployed form. That is, the outlet cover 100 of the present embodiment enables the operation of attaching and removing the outlet cover 100 simply by moving the outlet cover 100 toward or away from the switchboard 11, and In addition, since it is possible to attach and detach the outlet cover 100 while maintaining the insertion state of the wiring member 15 into the outlet 12, the workability is greatly improved.

Further, according to the outlet cover 100 of the present embodiment, in a state in which the plurality of wiring members 15 are surrounded by the band-shaped body 101, the narrowed portion 105 is tightened with the string-shaped member 106 like a purse, so that the top edge portion 102 side is tightened. By squeezing the opening of the top edge portion 102 side, the gap between the wiring member 15 and the opening can be narrowed. By passing the binding member 106 through the through holes 107, 107 facing each other while the wiring member 15 is surrounded by the band 101, the opening on the side of the top edge 102 is bound and the wiring in the opening on the side of the top edge 102 is secured. The gap with the material 15 can be further narrowed. In particular, in the conventional outlet cover (Patent Document 1), since the opening is simply narrowed down with a band, it is inevitable that a gap is generated between the wiring members. In addition, there is a possibility that dust and rats may enter through the gap. On the other hand, in the present embodiment, a drawstring structure (squeezed portion 105, string-like member 106) for narrowing the opening diameter and a binding structure (through hole 107, binding member 109) for binding the opening with the wiring material 15 therebetween are employed. By cooperating, the top edge portion 102 of the band-shaped body 101 surrounds the wiring member 15 one by one, and the opening on the top edge portion 102 side can be closed more tightly.
