And the said frame body cut | disconnected the notch part for band slip prevention in both edge parts of the said band insertion path, respectively.

E. Action Insert a screw into the screw insertion hole of the board, screw the board to the rail, bundle several wires, place it on the board frame, and use the binding band inserted through the band insertion passage. By bundling, the wires are bound and fixed. At this time, the binding band is prevented from shifting by the cutout portion for preventing the band from slipping.

When bundling and fixing a large number of wires, a plurality of boards with pins on one side wall and pin insertion holes on the other side wall are adjacent to each other, and the pins of one board are inserted into the pin insertion holes of the adjacent board. Insert to join the two. By repeating this connection, a plurality of substrates can be connected to each other. Then, the board group is screwed to the rail, and in the same manner as described above, the electric wires are bound on the frame bodies of the respective boards by the binding band.

F. Embodiment An embodiment of the electric wire binding base according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a base A for binding electric wires. Reference numeral 1 denotes a substrate made of synthetic resin, and a band insertion hole 2 as a band insertion passage penetrating in two directions on one end side in a longitudinal direction thereof. 3 is provided, and a screw insertion hole 5 is formed in the other end side. Further, a double-sided tape 6 is adhered to the back side of the substrate 1. Then, notches 2a, 2b, 3a and 3b for preventing band slip are cut off on the upper surface of the frame 4 and at both end portions of the band insertion holes 2 and 3, respectively.

The electric wire binding base A having the above configuration is used as shown in FIG. That is, the screw 9 is inserted into the screw insertion hole 5 of the board 1 and the board 1 is screwed to the rail 10 provided in the distribution board. Then, the three electric wires 7, 7, 7 in the gutter space in the distribution board are bundled, placed on the frame 4 of the substrate 1, and bound by the binding band 8 inserted into the band insertion hole 3. By doing so, the electric wires 7, 7, 7 can be easily bound and fixed. At this time, the binding band 8 is prevented from shifting by the notches 3a and 3b for preventing the band from slipping.

As shown in FIGS. 3 to 6, the electric wire binding base A can fix electric wires in multiple directions such as a vertical direction, a horizontal direction, a right diagonal direction, and a left diagonal direction. It is easy to fix regardless of the state of the electric wire.

Also, when fixing the wire binding base, it does not require a special rail, so it can be mounted anywhere in the distribution board, and since the wires are bound with a binding band, the thickness and binding of the wires There is no need to prepare and use several types of wire binding bases depending on the number or the like.

Further, since the frame 4 for binding the electric wires and the screw insertion hole 5 of the substrate 1 for fixing the base for binding the electric wires are separated from each other, it is possible to easily attach even the already connected portions.

In the present embodiment, the shape of the frame 4 is rectangular, but the shape is not limited to this, and may be circular or triangular as long as it meets the purpose of the present invention.

The number and direction of the band insertion holes are not limited to the present embodiment, and if the hole diameter of the band insertion hole is relatively small, the notch of the band slip prevention notch may be omitted. Is also good.

FIG. 7 shows a modified embodiment of the present invention, in which electric wire binding bases B and C are obtained by improving the electric wire binding base A shown in FIG.

In other words, the base B for binding electric wires is
And a pin insertion hole 12 through which the pins 11, 11 of the board 1 of the adjacent electric wire binding base C can be inserted at positions corresponding to the pins 11, 11 on the other side wall. , 12
Is provided.

The electric wire binding bases B and C thus configured are used as follows. That is, the pin insertion hole of the wire binding base B
The pins 11, 11 of the electric wire binding base C are inserted into 12, 12, and the two are integrally connected. Then, the electric wire binding bases having the same structure are sequentially connected to the electric wire binding base C as necessary.

This base group D is screwed to the rail 10, and each of the substrates 1, 1,.
Are bound by a binding band 8 on the frame body 4 of FIG. FIGS. 8 and 9 show examples of this state. The electric wires can be bound and fixed in the vertical and horizontal directions.

The electric wire bundling base having the above-described configuration can bind and fix a large number of electric wires by forming a base group, and has an advantage in part management as a unitized one.

As shown in FIG. 10, the wire binding base A can be screwed to the vertical rail 14 via the stay 13, so that the vertical space can be effectively used.

G. Effect of the present invention As described above, the wire binding base according to the present invention has a band insertion passage at one end side of the board, a screw insertion hole at the other end side, and A pin is protruded on one side wall, a pin insertion hole is provided on the other side wall, and notches for preventing band slip are cut off at both end edges of the band insertion passage. Since rails are not required, they can be easily installed in a distribution board without being restricted to a relatively small place.Because wires are bound by a binding band, the base for wire binding depends on the thickness and number of wires. There is no need to prepare and use several types of, and it is very versatile because the wires can be fixed in multiple directions.
In addition, since the frame body and the screw insertion hole are separated from each other, it is possible to easily attach even the already-connected portion. Furthermore, since the electric wire binding base is unitized, a large number of electric wires can be bound and joined by joining them.
Its practical value is great because it can be fixed and has advantages in parts management.
