Description

  The present invention is a distribution board comprising various electrical equipment, comprising at least a cabinet body having an opening on the front surface, a frame covering the entire periphery of the opening, and a wiring cover covering the entire opening, The wiring cover relates to a distribution board supported by a covering metal fitting.

  An opening is provided in the front surface of the cabinet body, and a frame body for connecting the door body is attached to the peripheral edge of the opening. An electrical device such as a main breaker or a branch breaker is arranged on a panel or the like, and the panel is housed in a cabinet body to constitute a distribution board. Electrical devices are connected by a conductor, and this portion is called a charging unit. In order to prevent dust and the like from entering the charging unit, the opening of the cabinet body is covered with a wiring cover.

As shown in FIG. 5, a mounting bracket 33 having a substantially L-shaped cross section is welded to the periphery of the opening 32 of the cabinet body 31. The attachment fitting 33 is provided with a frame attachment screw hole 34 and a cover attachment fitting screw hole 35, and the frame 36 and the cover attachment 37 are respectively attached by one attachment fitting 33.

  However, in the above mounting bracket, in order to mount the covering bracket, it is necessary to remove the frame body, and the work is very troublesome. In some cases, the position of the covering metal fitting is adjusted so that the wiring cover supported by the covering metal fitting reliably covers the opening. When the position of the covering metal fitting is adjusted after the distribution board is installed, the covering metal fitting cannot be moved unless the frame is removed.

  Therefore, in order to provide a distribution board for the purpose of improving workability, the present invention is provided with a frame body mounting bracket for mounting the frame body on the cabinet body and provided inside the side surface of the cabinet body. Cover metal fittings can be attached to the wire support.

  In the distribution board according to the present invention, the frame body mounting bracket for mounting the frame body to the cabinet body is provided in the cabinet body, and the covering bracket can be attached to the wire support provided inside the side surface of the cabinet body. Since the frame body attaching screw hole and the cover metal fitting screw hole are separated and the cover metal fitting can be attached with the frame body attached, workability is improved. Moreover, the position adjustment of the covering metal fittings after the distribution board is installed can be performed with the frame attached.

  A wiring cover mounting bracket according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The cabinet body 1 has an opening 2 on the front surface, and a main breaker 4 and a branch breaker 5 are arranged on a panel 3 and the like, and the panel 3 is fixed to the cabinet body 1 to constitute a distribution board 6. A frame body 8 for attaching the door body 7 to the cabinet body 1 is provided on the front surface of the cabinet body 1.

  The front opening 2 of the cabinet body 1 is covered with a wiring cover 9 to prevent dust from entering the cabinet body 1. The wiring cover 9 is supported by a covering metal fitting 10 provided on the cabinet body 1.

  An attachment fitting 11 for fixing the frame body 8 is provided on the periphery of the opening 2 of the cabinet body 1. The mounting bracket 11 forms a frame body mounting portion 12 and a cabinet mounting portion 13 in a substantially L-shaped cross section. The attachment fitting 11 is attached with the frame attachment portion 12 facing the inside of the opening 2 surface of the cabinet body 1. A screw hole 14 for screwing the frame body 8 is provided in the frame body mounting portion 12 of the mounting bracket 11. Further, the frame body 8 is provided with an insertion hole 15 for screwing the mounting bracket 11. The insertion hole 15 and the screw hole 14 are made to face each other, the frame body 8 is aligned with the cabinet body 1, the screw 16 is inserted into the insertion hole 15 and the screw hole 14, and the frame body 8 is fixed to the cabinet body 1.

  An electric wire support 17 is attached to the inner side surface of the cabinet body 1. A bundling hole 18 is provided so that wiring for connecting electric devices such as a breaker can be wired and the wiring can be bundled with a bundling tool. A fixing hole 19 for fixing the covering metal fitting 10 is provided in the electric wire support 17. The position where the fixing hole 19 is provided is a position close to the opening 2 when the wire support 17 is provided on the inner side surface of the cabinet body 1.

  The covering metal fitting 10 is composed of a fixing portion 20 and a support portion 21, and when the fixing portion 20 is screwed into a fixing hole 19 provided in the electric wire support 17, the support portion 21 is located inside the cabinet body 1. It becomes the form extended toward. An insertion hole 22 facing the fixing hole 19 of the wire support 17 is provided in the fixing portion 20 of the covering metal fitting 10.

  The fixing hole 19 and the insertion hole 22 are made to face each other, the covering metal fitting 10 is placed on the electric wire support 17, screws 23 are inserted into the fixing hole 19 and the insertion hole 22, respectively, and tightened. 17 to fix. By providing a plurality of fixing holes 19, the mounting position of the covering metal fitting 10 can be adjusted in accordance with the height of the equipment stored in the cabinet body 1.

  The mounting bracket 11 for mounting the frame body 8 on the cabinet body 1 and the covering bracket 10 for supporting the wiring cover covering the opening 2 of the cabinet body 1 are separated from each other, and the frame body 8 is mounted on the cabinet body 1 In this state, the covering metal fitting 10 is moved for attaching / detaching the covering metal fitting 10 and adjusting the attachment position of the wiring cover 9. Attaching the covering metal fitting 10 to the electric wire support 16 means that the fixing hole 19 is provided in the electric wire support 16, and it is easier to process the fixing hole 19 than to drill a hole in the cabinet body 1. There is also a merit.

It is the front view of the state which saw through the door body of the distribution board concerning the present invention, the right side view, and the lower side view. It is explanatory drawing which shows the electricity distribution panel which concerns on this invention. It is a principal part enlarged view of the distribution board in FIG. It is a side view of the distribution board in FIG. It is explanatory drawing which shows the conventional distribution board.
