JP-A-10-94116

However, the device mounting bracket of Patent Document 1 has a substantially L shape and is fixed to the side surface and the bottom surface of the box body. Therefore, when the wiring hole is required on the side surface, the device mounting bracket becomes a hindrance to the wiring hole. At the same time, the substantially L-shaped bottom mounting portion also serves as a fixing means for the base on which the electric device is placed, so that the mounting position of the device mounting bracket is also limited.

In addition, the binding band insertion hole provided in the device mounting bracket of the prior art requires the work of drawing the binding band inserted from the surface of one insertion hole through the back of the other insertion hole to the surface of the device mounting bracket. Therefore, the work in a limited space in the cabinet is very difficult. In particular, in recent years, there are problems such as a large number of electric wires that are bundled due to high performance of equipment, and the time required for the bundling work.

The present invention has been made in view of the above points, and an object of the present invention is to provide an electric / electronic equipment storage cabinet having an electric wire supporter that is easy to bind electric wires and excellent in versatility.

In the first invention, in an electric wire support having a substantially U-shaped cross section formed by integrally bending an electric wire support surface having a board mounting screw hole and upper and lower depth surfaces forming a depth, the electric wire support surface is symmetrical in the vertical direction. An electric wire support having a plurality of electric wire bundling pieces formed by notching to reach the depth surface is provided on the inner surface of the cabinet.

According to a second aspect of the present invention, the wire binding piece of the wire support has a shape protruding from upper and lower depth surfaces that form the depth of the wire support.

The third invention is characterized in that a convex portion is provided on the binding band locking side of the wire binding piece to prevent the binding band from coming off.

According to a fourth aspect of the present invention, the tip end portion of the wire binding piece is bent in the depth direction to prevent the wire from being damaged.

In the fifth invention, a plurality of spaced curved depressions are formed on the electric wire support surface of the electric wire support, the opposed curved surfaces of the pair of curved depressions are opened, and the gap is formed by the opening. A part of the wire support surface is used as a wire binding part, and the binding band inserted from one curved hollow part becomes an insertion guide surface along the curved surface of the curved concave part along the other curved surface. It has a binding band insertion hole to be inserted through.

According to the first aspect of the present invention, a plurality of wire bundling pieces formed by notching to reach a depth surface that is vertically symmetric with respect to the wire support surface, instead of the insertion hole of the conventional bundling band, Thus, it is not necessary to insert such a difficult binding band, and the wire binding work can be easily performed even in a narrow space of the cabinet.

In addition, by providing board mounting screw holes at the four corners of the wire support surface, it is possible to easily attach the board using the inner surface of the cabinet. This also has the effect of preventing a direct load from being applied to the terminals of the electrical equipment.

Furthermore, by providing a plurality of wire supporters of the present invention having a vertically symmetrical shape at an arbitrary position on the side surface in the cabinet, there is an effect that the above-mentioned application range becomes large, such as mounting of a plurality of substrates becomes possible.

According to the second invention, since the wire binding pieces are protruded from the wire support surface, the binding work can be easily performed even with a large number of wires wired in a narrow space of the cabinet.

According to the third invention, when many electric wires are bundled, loosening of the binding band can be considered due to secular change, but the protrusion provided on the binding band locking side prevents the loosening of the binding band. At the same time, it can be used as a band guide for bundling, so bundling can be performed easily.

According to the fourth aspect of the invention, by bending the tip end portion of the wire binding piece in the depth direction, it is possible to prevent the wire covering surface from being damaged by burr or burr at the leading edge of the wire binding piece formed by the notch processing. Furthermore, since it serves as a guide for the binding band during the wire binding operation, the wire binding operation can be easily performed, and there is an effect of preventing the binding band from coming off due to aging.

According to the fifth invention, by providing a pair of symmetrically curved depressions in the binding band insertion hole, the curved surface becomes an insertion guide surface for the binding band without limiting the insertion direction of the binding band. Since the binding band can be guided and inserted in a desired direction, the binding operation can be easily performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

A first embodiment of the present invention will be described with reference to FIGS.

The wire support surface 1a shown in FIG. 1 and the wire support surface 1a are integrally bent to form the depth surfaces 2 and 2, and the wire support 1 having a substantially U-shaped cross section has a plurality of notches provided on the wire support surface 1a. A plurality of electric wire binding pieces 4 formed by an open portion 5 in which a notch 10b formed in 10a and a depth surface 2 is continuous, and board mounting screw holes 6 provided at four corners of the electric wire support surface 1a are provided as a pair of supports. It is configured in a vertically symmetrical shape around the tool mounting hole 7.

The contact surfaces 3 and 3 formed by bending the stepping process 11 and the depth surfaces 2 and 2 applied to the wire support surface 1a are provided for the purpose of reinforcing the wire support 1 and preventing deformation. Further, the board mounting screw holes 6 provided at the four corners may be screw prepared holes or tapping screw holes.

As shown in FIG. 2, the wire support 1 is attached to an arbitrary position on the inner surface of the electrical / electronic equipment storage cabinet 21, for example, the side surface 24 of the main body 22, and the mounting nut 31 and the mounting screw 32 of FIG. It is attached so as to be detachable by attaching means such as a bolt 33 and a nut 34 of b).

Next, the electric wire binding procedure will be described with reference to FIG. In the insertion hole provided in the conventional device mounting bracket, it was necessary to work to pull out the binding band that was previously inserted from the surface of one insertion hole from the back of the other insertion hole to the surface of the device mounting bracket, Such work in the presence of many wires in a narrow space in the cabinet is very difficult.

However, the electric wire support 1 of the present invention is provided with a plurality of electric wire binding pieces 4 formed by the open portion 5 in which the notch 10a and the notch 10b are continuous, and the arranged electric wire bundle 41 is attached. It can be fastened and fixed by the binding band 42 together with the wire binding pieces 4.

That is, since the binding support of the wire bundle 41 is completed by fastening the wire binding piece 4 and the wire bundle 41 with the binding band 42, it is necessary to insert the binding band 42 into the insertion hole of the binding band that is difficult to insert as in the prior art. Now, bundling work can be done easily even in a narrow cabinet.

It is also possible to temporarily fix the bundle of wires 41 arranged in advance with a bundling band 42 and tighten the bundling band 42 temporarily fixed from the tip 4a of the bundling piece 4 together with the bundling piece 4 to arrange and support the bundling of wires. Can be done efficiently.

In the cabinet 21 for storing electrical and electronic equipment, there is a case where a substrate 26 for attaching a device or the like is provided on the inner surface, for example, on the side surface 24 of the main body 22. Since it was not possible, it was necessary to remove and provide a substrate mounting device.

However, since the board mounting screw holes 6 are provided at the four corners of the wire support surface 1a of the wire support 1 of the present invention shown in FIG. The board 26 can be attached to the board mounting screw holes 6, 6 of the wire support 1 with the board mounting screws 27, 27.

Further, since the wire support 1 is formed in a vertically symmetrical shape with the pair of support attachment holes 7 as the center, when one of the symmetrical shapes is used for mounting the substrate 26, the wire bundle is connected to the other wire binding piece 4. If the 41 is bound and supported, it is possible to prevent the device (not shown) attached to the substrate 26 from being directly loaded.

Further, in addition to the combination of the above-described board attachment and electric wire support, and also being detachable, a plurality of electric wire supports 1 as shown in FIGS. 6A to 6C are used. Since it is possible to provide a cabinet for storing electrical and electronic equipment in which the substrate 26 can be mounted in various forms, it has become possible to respond to a wide range of customer requests.

In addition to the above, the wire support 1 is provided with a ground terminal screw hole 8 for connecting a ground terminal (not shown) to the wire support surface 1a and a plurality of multipurpose mounting holes 9. As a specific example of the use of the multipurpose mounting hole 9, a push-type binding band (not shown) whose tip is different from the normal shape of the binding band 42 is inserted into the multipurpose mounting hole 9. In addition to bundling the wire bundle 41, it can also be used as a mounting hole for small parts, further expanding the usage of the wire support 1.

A second embodiment of the present invention will be described with reference to FIG.

Since the plurality of electric wire binding pieces 4 are formed so as to protrude from the depth surfaces 2 and 2 having a substantially U-shaped cross section, the binding work is facilitated. Further, by forming the tip end portion 4a of the wire binding piece 4 into a mountain shape, a binding band 42 (not shown) in a state of temporarily binding the wire bundle 41 (not shown) into a ring is formed on the wire binding piece 4. It becomes an insertion guide when inserting and bundling, and bundling work can be easily performed.

A third embodiment of the present invention will be described with reference to FIG.

When a bundle of wires 41 (not shown) of different types and sizes are bundled and supported on the wire binding piece 4 of the wire support 1, loosening occurs in the binding band 42 (not shown) due to vibration or aging, In the worst case, there is a risk of disconnection from the wire binding piece 4. Protrusions 4c and 4c are provided at the tips of binding band locking sides 4b and 4b corresponding to two opposite sides of the three sides of the wire binding piece 4, and the binding band 42 (not shown) described above as a problem. Measures to prevent detachment.

Further, during normal binding work, the convex portions 4c and 4c serve as guides, and the work can be easily performed such that the binding position of the binding band 42 (not shown) is stabilized and the band is prevented from being displaced.

A fourth embodiment of the present invention will be described with reference to FIG.

By bending the protruding end portion 4a of the wire binding piece 4 in the depth direction, the burr and burr of the tip end of the wire binding piece formed by the notching process do not directly contact the wire covering surface, and the binding band 42 It is possible to prevent the wire covering surface from being damaged when the wire bundle 41 is bundled.

Further, since the bent portion serves as a guide for the binding band 42 at the time of the wire binding work as in the third embodiment, the wire binding work can be easily performed, and the detachment due to the loosening of the binding band 42 due to secular change can be prevented. It can also be prevented.

A fifth embodiment of the present invention will be described with reference to FIGS.

The binding band insertion hole 43 for inserting and binding the electric wire forms a plurality of curved concave portions 44, 44 that are spaced apart from the electric wire support surface 1 a, and the concave portions 44, 44 The opposing curved surfaces 45, 45 were opened so that the binding band 42 could be inserted, and a part of the wire support surface 1a between the openings 46, 46 was defined as the wire binding portion 1b.

The binding band 42 inserted from one curved depression 44 is guided and bundled along the curved surface 45 of the other curved depression 44 through the openings 46 and 46 with the curved surface 45 serving as an insertion guide surface. Since the band 42 can be inserted, the electric wire bundle 41 can be easily bundled together with the electric wire binding portion 1b, and the electric wire bundle 41 can be supported.

Conventionally, this type of wire bundling structure has a bundling band inserted from one of a pair of insertion holes provided on the electric wire support surface and inserted into the other insertion hole from the back side of the electric wire support surface to bind the electric wire support surface and the electric wire. Although it supports, the operation which guides a binding band to the insertion hole in the back surface of an electric wire support surface was difficult.

However, in the binding band insertion hole 43 having the above-described structure according to the present invention, the curved surface 45 of the curved recess 44 serves as the insertion guide surface of the binding band 42 and is guided to the other curved recess 44 that has been separated. Thus, there is an effect that the guide operation on the back surface of the electric wire support surface is unnecessary and the electric wire support operation can be easily performed. Furthermore, since the pair of curved hollow portions 44 and 44 are symmetrical, there is an effect that the workability can be improved without limiting the insertion direction of the binding band 42.

Further, as shown in FIG. 11, by forming the curved surfaces 45, 45 of the openings 46, 46 of the pair of symmetrically curved concave portions 44, 44 upward in the direction of the electric wire support surface, the curved concave portions 44 are formed. The tip of the binding band 42 inserted through is forcibly guided along the upward direction of the curved surface 45 so that the insertion work can be performed easily.
