Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a distribution board for fixing a frame having an internal unit such as a breaker mounted on a support member provided at the bottom of a box.

[0002]

[Prior art]

 In general, the distribution board may be installed in parallel with other control boards, etc., but it is necessary to make the depth and the like of the box the same size in order not to impair the appearance. However, if the depth of the box is made deeper, the position where the internal device such as a breaker is attached also becomes deeper, so that the handle of the breaker is projected from the inner lid interposed between the box and the door that closes the opening of the box. I can't. Therefore, when the box becomes deep, it is necessary to lift the internal device such as a breaker from the bottom of the box to some extent.

Therefore, when the box 10 having a large depth is used for the distribution board, as shown in FIG. 7, the inner unit supporting member 40 is inserted between the frame 20 and the inner unit 21 to form the inner unit. Lift 21 from bottom 11 and secure. As shown in FIG. 8, this inner unit supporting member 40 connects the upper and lower horizontal pieces 42, 43 having a plurality of insertion holes 45 for inserting the fixing screws 41 and the upper and lower horizontal pieces 42, 43. The vertical piece 44 is formed into a rectangular tube shape.

To fix the internal unit 21 to the box 10, first, the screw hole 26 of the internal unit support member 40 and the internal unit 21 are inserted into the screw holes 26 of the frame 20 fixed to the bottom 11 of the box 10. The insertion hole 23a is polymerized. Next, the fixing screw 41 is screwed into the screw hole 26 from the insertion hole 23a.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The members having the same basic functions as those of the conventional example are designated by the same reference numerals.

Reference numeral 10 denotes a box, which has a bottom portion 11 provided with four support members 13 having male screws 15 and side portions 12 erected from four circumferences thereof, and is formed in a box shape having an opening on one surface. . The support member 13 is formed to have a substantially convex cross section, is fixed to the bottom portion 11 by welding or the like, and has a support member main body 14 having a large diameter portion and two small diameter portions on the upper surface, and the large diameter portion. It is configured by a male screw 15 which is fitted and whose rotation of the head is restricted by a small diameter portion.

Reference numeral 20 denotes a frame, as shown in FIG. 1, on which an internal unit 21 including a breaker 22 is mounted and supported by a supporting member 13. The inner unit 21 includes a breaker 22 and a breaker fixing member 23 that fixes the breaker 22. The breaker fixing member 23 is formed with a screw hole 23a for fixing to the frame 20. The frame 20 is formed of an iron plate or the like in a generally inverted concave shape in cross section, and has a through hole 24 and a cut groove 25 for fixing to a frame fixing member, which will be described later, at both ends of the upper surface in the longitudinal direction. A screw hole 26 for fixing the inner device 21 is formed between the groove 24 and the cut groove 25.

Reference numeral 30 denotes a frame fixing member, which is formed in a convex shape in a side view with an iron plate or the like, and is fixed to the supporting member 13 with the male screw 15 inserted therethrough, and a frame. The frame 20 has a supporting portion 32 (second horizontal piece) that abuts and supports the 20 and a fixing screw portion 33 (bolt) that is positioned coaxially with the male screw 15 and projects from the supporting portion 32. Is placed between the bottom portion 11 and the frame 20 so as to be positioned with a predetermined distance from the bottom portion 11. The fixed portion 31 and the support portion 32 are connected by a rotation regulating portion 34 that regulates rotation. Note that the predetermined interval described here is the interval at which the internal unit is separated from the bottom at a position where the handle of the breaker can project from the inner lid that is interposed between the bottom and the door that closes the opening of the box.

In the fixed portion 31, a plurality of insertion holes 35 through which the male screw 15 is inserted are arranged side by side in the longitudinal direction of the frame 20. In the support portion 32, a screw portion of a fixing screw portion 33, which will be described later, is loosely engaged, and the fixing screw portion 33 forms a long hole 36 which is movable in the longitudinal direction of the frame 20. The long hole 36 has a large-diameter portion 36a into which the head portion of the fixing screw portion 33 is fitted and a small-diameter portion 36b to which the head portion of the fixing screw portion 33 is locked at both ends. Is forming. The fixing screw portion 33 has a head portion 37 having a hexagonal shape and a screw portion 38 protruding from the long hole 36 and screwed into the nut 39.

In order to fix the internal unit 20 to the box 10, first, the male screw 15 of the supporting member 13 is inserted into the insertion hole 35 of the frame fixing member 30, and the nut is screwed to fix the frame. The member 30 is fixed. Next, the head portion 37 of the fixing screw portion 33 is inserted from the large diameter portion 36a of the long hole 36 and moved to the small diameter portion 36b to mount the fixing screw portion 33. Next, with the screw portion 37 of the fixing screw portion 33 inserted in the through hole 24 and the cut groove 25 of the frame 20, the nut 39 is screwed to fix the frame 20. Next, with the screw holes 23a at both ends of the breaker fixing member 23 being overlapped with the screw holes 26 of the frame 20, a fixing screw (not shown) is screwed onto the frame 20 from the upper surface of the breaker fixing member 23. And by.

The number of frame fixing members is not limited to four, and the number may be appropriately increased according to the length of the frame in the longitudinal direction. Further, the height of the frame fixing member may be appropriately designed according to the depth of the box.

Further, according to the present embodiment, the fixing screw portion is mounted by being inserted from the elongated hole, but the screw portion may be projected and fixed to the support portion so as to fix the frame. . Further, if the fixing screw portion is movably mounted between the support portion and the fixing portion without forming the large diameter portion in the long hole, the fixing screw portion will not be lost.

[0025]

[Effect of device]

 According to the distribution board of claim 1, when the frame is fixed to the bottom of the box, the entire inner unit mounted on the frame is separated from the bottom at a predetermined interval, so that the inner unit supporting member is fixed without using. This makes it easier to fix the internal unit.

According to the distribution board according to the second aspect, the screw for fixing the frame fixing member to the box and the screw for fixing the frame to the frame fixing member can be separately provided. In addition, after fixing the frame fixing member to the box, the frame can be fixed to the frame fixing member, and the work of fixing the internal unit becomes easier.

According to the distribution board of claim 3, the bolt can be moved without rotating the head within the elongated hole provided in the longitudinal direction of the frame, and in addition to the effect of claim 2, When fixing the frame, it is possible to make fine adjustments in the longitudinal direction of the frame, which facilitates the work of fixing the frame.

According to the distribution board of claim 4, the head portion of the bolt can be fitted into the elongated hole from the large diameter portion. In addition to the effect of claim 3, the bolt is formed as a separate body. Therefore, the frame fixing member can be easily manufactured.

According to the distribution board of claim 5, the position of the frame fixed to the frame fixing member in the longitudinal direction can be changed. In addition to the effects of claims 2 to 4, the length in the longitudinal direction can be changed. It can be fixed on frames with different sizes.
