  First, a first embodiment of an electric equipment storage box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The electric device storage box 1 includes a back plate 3 to which various electric devices such as a power distribution device, a control device, and a communication device are attached, and a front frame 7 that is attached to the back plate 3 with the front and back surfaces opened. The door body 8 is provided at the front opening of the front frame 7.

  The back plate 3 is formed in a thin box shape with a rectangular metal plate material. Upright pieces 3 a are formed by bending forward on the top, bottom, left and right edges of the back plate 3. A contact piece 3b that contacts the front frame 7 is formed on the rising piece 3a by bending inward.

  The front frame 7 is integrally formed by a metal top plate 4, bottom plate 5, and left and right side plates 6 and 6. An opening 7 f (see FIG. 9) is formed on the front surface of the front frame 7, and an opening 7 r is formed on the back surface of the front frame 7. A contact piece 7a is formed on the periphery of the rear side of the front frame 7 by bending inward, and contacts the contact piece 3b on the front side of the back plate 3 in an assembled state. The left and right and lower abutting pieces 7a are further bent to the back side, and a positioning piece 7b for the back plate 3 is formed. At the lower end portion of the positioning piece 7b, hooking pieces 7c, 7c that are hooked on the lower contact piece 3b of the back plate 3 are formed so as to protrude downward. A pair of left and right latches 9, 9 that can be engaged with and disengaged from the contact piece 3 b on the upper side of the back plate 3 are provided on the contact piece 7 a on the upper side of the front frame 7. A frame portion 7d is formed in a quadrangular annular shape at the front side of the front frame 7 so as to surround the door body 8.

  An input / output line portion 19 is formed at the upper and lower joining portions of the back plate 3 and the front frame 7. The input / output line portion 19 of the back plate 3 is formed in a concave shape on the upright piece 3a, the input / output line portion 19 of the front frame 7 is formed in a concave shape on the top plate 4 and the bottom plate 5, and the input / output lines of the back plate 3 and the front frame 7 are formed. By combining the portions 19 and 19, a rectangular opening is formed at the joint. A cushion member 20 is provided in each of the back plate 3 and the front frame 7 to close the opening. The cushion member 20 includes an outer cushion member 20a and an inner cushion member 20b. The outer cushion member 20a and the inner cushion member 20b are arranged in two rows orthogonal to the wiring direction of the electric wire 21, and further, the outer cushion member 20a and the inner cushion member 20b. The members 20b are arranged in steps. The cushion member 20 is formed with a plurality of slits 20 c in order to improve the adhesion with the electric wire 21.

  An electric wire support plate 23 for fastening and fixing the electric wire 21 to the fastening material 22 is fixed to the back plate 3 with screws 24 so as to be in close contact with the cushion member 20. Moreover, the insertion hole 23a of the screw 24 which fixes the electric wire support plate 23 is formed in a long hole shape, and it can be moved in the radial direction of the electric wire 21 to be inserted, and is provided so that the position can be adjusted.

  The door body 8 is a hinge that is formed in a size that fits into the frame portion 7d of the front frame 7 by bending the upper and lower and left and right peripheral edges of the metal plate material in the rear, and is fitted to the frame portion 7d of the front frame 7. 10 is attached to the frame portion 7d of the front frame 7 so as to be freely opened and closed. On the side opposite to the hinge 10, a handle 15 is provided for locking the door body 8 in the closed position to the frame portion 7d.

  The electrical equipment storage box 1 configured as described above has the back plate 3 attached to the wall surface of the building, and the panel 17 on which the electrical equipment 40 (see FIG. 9) is mounted on the back plate 3 attached to the wall surface. It is done. Then, the electric wire 21 to be wired to the electric device 40 is inserted into the input / output line portion 19 and is fastened and fixed to the hole 23b formed in the electric wire support plate 23 of the back plate 3 using a fastening material 22 such as a binding band or string. . At this time, the position of the wire support plate 23 is adjusted according to the thickness of the wire 21. Then, the front frame 7 to which the door body 8 is attached is assembled to the back plate 3.

  When assembling the front frame 7, hold the front frame 7 so that the upper part is slightly inclined toward the front side, and fit the positioning pieces 7 b and 7 b of the front frame 7 between the contact pieces 3 b and 3 b on the left and right sides of the back plate 3. The hook pieces 7c, 7c of the front frame 7 are engaged with the contact piece 3b on the lower side of the back plate 3 so as to be further dropped. Then, by pressing the upper part of the front frame 7 against the back plate 3, the latch 9 is locked to the contact piece 3 b and the front frame 7 is detachably fixed to the back plate 3.

  Since the outer cushion member 20a and the inner cushion member 20b are arranged in steps, the electric wire 21 inserted through the input / output line portion 19 is in close contact with the cushion member 20 with no gap between the thin electric wire and the thick electric wire. In addition, since the cushion member 20 is in close contact with the electric wire support plate 23, the electric wire 21 is prevented from falling in the insertion direction, and the cushion member 20 and the electric wire 21 are improved in adhesion.

  The material, shape, and structure of the cushion member are not limited, and the shape and structure of the back plate and front frame can be changed as appropriate without departing from the spirit of the present invention.

  Next, a second embodiment of the electrical equipment storage box according to the present invention will be described with reference to the accompanying drawings of FIGS. The electrical equipment storage box 31 of the second embodiment is different from the first embodiment mainly in the cushion member mounting structure.
