Description

本発明は、住宅用分電盤の充電部カバーに関するものである。   The present invention relates to a charging unit cover for a residential distribution board.

従来、住宅用分電盤の充電部カバー２４には特許文献１に示すような、主幹回路遮断器の負荷側端子部と各給電バーとを接続する３本の導体２８のうち、１本又は２本の導体２８の導体２８本体を幅方向を分電箱体の底板に対して水平状として、他の２本又は１本の導体２８の導体２８本体を幅方向を箱体本体の底板に対して垂直状として形成して、水平状の１本又は２本の導体２８の下方に垂直状の他の導体２８を配置して、１本又は２本の導体２８の水平状の導体２８本体を充電部カバー２４の上部に形成した水平溝部に嵌合し、導体２８の端子板部を主幹回路遮断器の負荷側端子部に接続するとともに接続端子板部を給電バーにネジ止めしたものであるので、導体２８が水平溝部の下方壁面部を抑えることとなり充電部カバー２４が上方より離脱する虞の全くない住宅用分電盤がある。
特許第３２８４１５７ Conventionally, the charging part cover 24 of the residential distribution board has one or three of the three conductors 28 connecting the load side terminal part of the main circuit breaker and each feeding bar as shown in Patent Document 1. The conductor 28 main body of the two conductors 28 is made horizontal in the width direction with respect to the bottom plate of the distribution box body, and the conductor 28 main body of the other two or one conductors 28 is set to the bottom plate of the box main body. The horizontal conductor 28 body of the one or two conductors 28 is formed as a vertical shape, and another vertical conductor 28 is disposed below the one or two horizontal conductors 28. Is fitted into a horizontal groove formed in the upper part of the charging unit cover 24, and the terminal plate portion of the conductor 28 is connected to the load side terminal portion of the main circuit breaker and the connection terminal plate portion is screwed to the power supply bar. As a result, the conductor 28 restrains the lower wall surface of the horizontal groove and the charging unit cover 24 is There is absolutely no residential distribution board of the possibility that the more detached.
Patent No. 3284157

しかしながら、特許文献１に記載の発明では主幹開閉器と分岐開閉器を接続する導体を覆うと共に胴体を収納する充電部カバーによって被覆されるため、温度上昇の原因となるという欠点があった。又、温度上昇により、材質によっては充電部カバーが変形する恐れがあるという欠点があった。   However, the invention described in Patent Document 1 has a drawback in that it increases the temperature because it covers the conductor connecting the main switch and the branch switch and is covered by the charging unit cover that houses the trunk. In addition, there is a drawback that the charging unit cover may be deformed depending on the material due to the temperature rise.

又、人体への感電等の恐れを少なくするために充電部カバーを設けているが、規格により住宅用分電盤内部の温度を一定以下に保つ必要があるため、導体の全面を被覆していない場合があるという欠点があった。   In order to reduce the risk of electric shock to the human body, etc., a charging section cover is provided, but the temperature inside the distribution board for housing needs to be kept below a certain level according to the standard, so the entire surface of the conductor is covered. There was a disadvantage that there may not be.

このため、本発明によって解決しようとする課題は、少なくとも前面に開口部を備えた箱体本体と、この箱体本体の開口部を被覆する扉体と箱体本体内部に固定される機器取付板とからなる住宅用分電盤において、人体への感電等の恐れを少なくすることが可能であると共に放熱性を高めた住宅用分電盤の充電部カバーを提供することにある。   For this reason, the problem to be solved by the present invention is a box body having an opening at least on the front surface, a door covering the opening of the box body, and a device mounting plate fixed inside the box body. It is an object of the present invention to provide a charging part cover for a residential distribution board that can reduce the risk of electric shock to the human body and that has improved heat dissipation.

上記した課題を解決するためになされた本発明の住宅用分電盤の充電部カバーは、少なくとも前面に開口部を備えた箱体本体とこの箱体本体の開口部を被覆すると共に開閉可能な扉体を設けた蓋体と箱体本体の内部に固定される機器取付板とからなる分電盤の、機器取付板に取り付けられる主幹回路遮断器と分岐回路遮断器とを接続する導体を被覆する充電部カバーにおいて、略Ｌ字状に形成され、底面と側面と上面に放熱手段を設けた。 The charging part cover of the distribution board for houses of the present invention made to solve the above-described problem is capable of covering and opening and closing the box body having an opening on the front surface and the opening of the box body. Covers the conductor that connects the main circuit breaker attached to the device mounting plate and the branch circuit breaker of the distribution board consisting of the lid provided with the door and the device mounting plate fixed inside the box body. The charging portion cover is formed in a substantially L shape, and heat dissipating means is provided on the bottom surface, side surface, and top surface .

本発明の分電盤入出線固定構造によれば、少なくとも前面に開口部を備えた箱体本体と、箱体本体の開口部を被覆する扉体と箱体本体内部に固定される機器取付板とからなる分電盤において、充電部カバーに放熱手段を設けることによって充電部カバーによって被覆される導体部分の温度上昇を抑えることが可能である。又、温度上昇による充電部カバーの変形等を防ぐことが可能である。   According to the distribution board input / output fixing structure of the present invention, a box body having an opening at least on the front surface, a door covering the opening of the box body, and a device mounting plate fixed inside the box body In the distribution board comprising the above, it is possible to suppress the temperature rise of the conductor portion covered by the charging unit cover by providing the heat dissipating means on the charging unit cover. In addition, it is possible to prevent deformation of the charging unit cover due to temperature rise.

又、充電部カバーによって導体のほぼ全面を被覆するため、人体への感電等を防ぐことが可能である。   In addition, since almost the entire surface of the conductor is covered with the charging unit cover, it is possible to prevent an electric shock to the human body.

本発明では、安全性と放熱性を確保した住宅用分電盤の充電部カバーを少ない部品数で可能にした。   In the present invention, the charging part cover of the distribution board for homes that ensures safety and heat dissipation is made possible with a small number of parts.

以下、本発明の実施の形態を説明する。
少なくとも前面に開口部２を備えた箱体本体１、１１と箱体本体１、１１の開口部２を被覆する扉体と箱体本体１、１１内部に固定される機器取付板３、１３とからなる分電盤の、機器取付板３、１３に取り付けられる主幹回路遮断器６、１６と分岐回路遮断器７、１７とを接続する導体を被覆する充電部カバー４、１４において、充電部カバー４、１４に放熱手段１５を設けた。充電部カバー４、１４は略Ｌ字状に形成され、底面と側面と上面にはスリットによる放熱手段１５を設けた。これにより、充電部カバー４、１４の放熱性を高めることが可能である。又、導体のほぼ全面を被覆するため、作業者が誤って通電状態のまま導体に触れてしまう等して、感電する恐れを防ぐことが可能である。 Embodiments of the present invention will be described below.
A box body 1, 11 having an opening 2 at least on the front surface, a door covering the opening 2 of the box body 1, 11, and device mounting plates 3, 13 fixed inside the box body 1, 11; In the charging part covers 4 and 14 covering the conductors connecting the main circuit breakers 6 and 16 and the branch circuit breakers 7 and 17 attached to the device mounting plates 3 and 13 of the distribution board comprising 4 and 14 are provided with heat dissipating means 15. The charging unit covers 4 and 14 are formed in a substantially L shape, and heat radiating means 15 by slits is provided on the bottom, side and top surfaces. Thereby, it is possible to improve the heat dissipation of the charging part covers 4 and 14. In addition, since almost the entire surface of the conductor is covered, it is possible to prevent the possibility of an electric shock by, for example, an operator accidentally touching the conductor while being energized.

以上のように、本発明の住宅用分電盤の充電部カバーは導体を被覆する充電部カバーに放熱手段を設け、安全性と放熱性を確保した住宅用分電盤の充電部カバーを少ない部品数で提供できるものである。   As described above, the charging part cover of the residential distribution board according to the present invention is provided with heat dissipating means on the charging part cover that covers the conductor, and the charging part cover of the residential distribution board that secures safety and heat dissipation is small. It can be provided by the number of parts.
