Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a conductor support device used for attaching a connecting conductor made of a copper plate or the like and its protective cover inside a distribution board or the like.

(Prior art) Connecting conductors made of copper plates or the like are installed inside distribution boards, etc. for connection with branch breakers, and protective covers are provided to protect these connecting conductors from arc gas generated when the breakers operate. However, it is necessary to change the support height of the protective cover depending on the size of the branch breaker. For this reason, in the past, many supports with different heights of protective cover support parts were prepared and used depending on the needs, so it was necessary to manufacture an extremely wide variety of supports with similar shapes, and each The cost is high because molds need to be manufactured at the same time, and inventory management is also troublesome.Additionally, when there are changes in the specifications of the distribution board or special orders are made, it is extremely difficult to reassemble the support. There were also some complications.

(Problems that the invention attempts to solve) This invention solves these conventional problems,
This device was completed with the aim of creating a conductor support device that does not require the manufacture and storage of many types of supports and can easily support protective covers at various heights.

(Means for solving the problem) The present invention has multiple screw holes for attaching conductors on the top surface,
a recess located between these screw holes, and an insulating support body having a screw insertion hole opened in the recess for a mounting screw to be inserted from the lower surface; and a spacer for mounting the protective cover, which is engaged and fixed vertically onto the support body by the mounting screw.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. 1 is made of an insulating material such as plastic, and the upper surface thereof has a plurality of screw holes 2 for attaching a conductor.
and a concave portion 3 located between these screw holes 2.
It is an elongated support body equipped with. A screw insertion hole 5 for a mounting screw 4 inserted from the lower surface of the support 1 is opened in the recessed portion 3 . The support 1 is fixed onto a base 30 of a distribution board or the like by means of mounting screws 7 inserted into mounting holes 6 at both ends thereof. Shallow grooves 8 as shown in the figure are formed on the top and side surfaces corresponding to the concave portion 3 and the mounting holes 6 at both ends of the support 1, so that the partition wall 40 between the branch conductors 50 shown in FIG. Preferably, it can be supported. Reference numeral 9 denotes a spacer for attaching the protective cover, and as shown in FIG. It is fixed vertically on the body 1. For this reason, at least the lower end of the spacer 9 shall have a cross-sectional shape corresponding to the concave portion 3, and a screw hole 10 for the mounting screw 4 is formed at the lower end of the spacer 9, and a protective cover is provided at the upper end of the spacer 9. Screw hole 11 for mounting
is formed. The height of the spacer 9 is, for example, 30
Multiple types shall be manufactured in mm, 40mm, 50mm, etc. Note that it is preferable to form shallow grooves 12 similar to the grooves 8 of the support 1 on both front and rear sides of the spacer 9.

(Function) As shown in FIGS. 2 and 3, with this structure, first, a spacer 9 for attaching a protective cover is placed in the recessed part 3 between the screw holes 2 on the upper surface of the support 1. After engaging the lower ends, insert the mounting screw 4 from the lower surface into the screw insertion hole 5 opened in the recessed part 3 and tighten using the screw hole 10 of the spacer 9.
A spacer 9 is fixed vertically on the support 1. Next, the support 1 is fixed onto a base 30 of a distribution board or the like using the mounting holes 6 at both ends with mounting screws 7, and the connecting conductor 50 is inserted into the screw hole 2 on the top surface of the support 1. The connecting conductor is fixed by the connecting conductor mounting screws 13, and the protective cover 41 is mounted on the upper surface of the spacer 9 by the protective cover mounting screws 14, as shown in FIG. As mentioned above, multiple types of spacers 9 are available with different heights, so by selecting one with an appropriate height, the protective cover 41 can be supported at an arbitrary height. Further, since the spacer 9 is fixed on the support body 1 by engaging its lower end with the recessed part 3 of the support body 1, there is no wobbling, and the protective cover 41
It is possible to accurately support the following. Note that the downwardly bent end surface 42 of the protective cover 41 can be inserted into the groove 8 on the upper surface of the support 1 and supported.
Further, as shown in FIG. 3, the partition wall 40 can be supported using the grooves 12 on the side surfaces of the spacer 9 and the grooves 8 on the side surfaces of the support body 1.

(Effect of the invention) As is clear from the above explanation, the present invention has a structure in which a conductor is mounted on the top surface in order to support the connecting conductor inside the distribution board, etc. and to support the protective cover at various heights. By using a combination of a support with multiple screw holes and a recess with a screw insertion hole located in the middle, and a spacer for attaching the protective cover, it is possible to install the protective cover at various heights, unlike conventional methods. There is no need to prepare a support body with a support part, which saves the trouble of manufacturing and storing it, and also makes it possible to respond immediately when there are changes in the specifications of the distribution board or special orders are received. This is what I did. Another advantage is that the spacer for attaching the protective conductor can also be used to support the partition between the connecting conductors. Therefore, the present invention eliminates the problems of conventional conductor support devices of this type.
Its practical value is extremely great.
