Description

本発明は、配電線の接続部分の絶縁を行う絶縁カバー、及び、絶縁カバーに取り付ける接触抑制具に関する。 The present invention relates to an insulating cover that insulates a connection portion of a distribution line, and a contact suppressor attached to the insulating cover.

近年では、図６に示すように、開閉器１００から延設される開閉器リード線１１００と高圧縁廻電線１２００との接続部分に、ゴムやプラスチックなどの絶縁材で形成される絶縁カバー６が取り付けられている。 In recent years, as shown in FIG. 6, an insulating cover 6 made of an insulating material such as rubber or plastic has been provided at a connection portion between a switch lead wire 1100 extending from a switch 100 and a high-voltage peripheral electric wire 1200. It is attached.

従来の絶縁カバー６は、非特許文献１及び図７（ａ）に示すように、上下方向に長尺な箱状に形成され、内部空間を有している。この絶縁カバー６のカバー蓋６１０には、開閉器リード線１１００と高圧縁廻電線１２００とを挿入する開口である第一挿入孔６１１ａ及び第二挿入孔６１１ｂが形成される。また、カバー蓋６１０の第一挿入孔６１１ａと第二挿入孔６１１ｂとの間及び第一挿入孔６１１ａ及び第二挿入孔６１１ｂのそれぞれからカバー蓋６１０の端部にかけて、一直線上にカバー蓋６１０を分割する割面部６１２を有する。この割面部６１２により、開閉器リード線１１００及び高圧縁廻電線１２００が接続された状態で、絶縁カバー６に挿入することができる。 As shown in Non-Patent Document 1 and FIG. 7A, the conventional insulating cover 6 is formed in a vertically long box shape and has an internal space. The cover lid 610 of the insulating cover 6 is formed with a first insertion hole 611a and a second insertion hole 611b, which are openings for inserting the switch lead wire 1100 and the high-voltage peripheral electric wire 1200. Further, the cover lid 610 is placed in a straight line between the first insertion hole 611a and the second insertion hole 611b of the cover lid 610 and from each of the first insertion hole 611a and the second insertion hole 611b to the end of the cover lid 610. It has a split surface portion 612 to be divided. The split surface portion 612 allows the switch lead wire 1100 and the high-voltage peripheral wire 1200 to be inserted into the insulating cover 6 in a connected state.

開閉器リード線１１００と高圧縁廻電線１２００とは、それぞれの先端の被覆を取り除いた部分（以下、先端部分という）が重ねられて、ボルト１４０ａ及びナット１４０ｂにより固定される。これら開閉器リード線１１００及び高圧縁廻電線１２００の各先端部分とボルト１４０ａとナット１４０ｂとが、接続部１５０を構成する。 The switch lead wire 1100 and the high-voltage peripheral electric wire 1200 are overlapped with a portion (hereinafter referred to as a tip portion) from which the coating on the tip thereof has been removed, and are fixed by bolts 140a and nuts 140b. Each tip portion of the switch lead wire 1100 and the high-voltage peripheral wire 1200, a bolt 140a, and a nut 140b constitute a connection portion 150.

そして、当該接続部は、図７（ｂ）に示すように、絶縁カバー６が有する内部空間に位置するように絶縁カバー６に収納される。これにより、絶縁カバー６は、接続部１５０を絶縁する。 Then, as shown in FIG. 7B, the connection portion is housed in the insulating cover 6 so as to be located in the internal space of the insulating cover 6. As a result, the insulating cover 6 insulates the connecting portion 150.

ここで、各絶縁カバー６は、開閉器リード線１１００と高圧縁廻電線１２００との接続部分に取り付けられた状態で吊持されるため、強風や電柱の揺動などにより絶縁カバー６が揺動する可能性がある。 Here, since each insulating cover 6 is suspended while being attached to the connection portion between the switch lead wire 1100 and the high-voltage peripheral electric wire 1200, the insulating cover 6 swings due to a strong wind or a swing of a utility pole. there's a possibility that.

発明者の検討の結果、以下の課題が見いだされた。
すなわち、図８に示すように、屋外の環境下において、絶縁カバー６の外面に塩やホコリなどの汚れが付着する。 As a result of the inventor's examination, the following problems were found.
That is, as shown in FIG. 8, dirt such as salt and dust adheres to the outer surface of the insulating cover 6 in an outdoor environment.

また、絶縁カバー６の内部にもカバー蓋６１０の第一挿入孔６１１ａ及び第二挿入孔６１１ｂからの雨水の浸入などにより、接続部１５０に汚れが付着する可能性がある。
この絶縁カバー６の内外面に付着した汚れにより、絶縁カバー６には、図８に示すように、第一挿入孔６１１ａ、第二挿入孔６１１ｂを介して、絶縁カバー６の外側表面から接続部１５０に至る電路１９０が形成される。 Further, there is a possibility that dirt may adhere to the connection portion 150 inside the insulating cover 6 due to the infiltration of rainwater from the first insertion hole 611a and the second insertion hole 611b of the cover lid 610.
Due to the dirt adhering to the inner and outer surfaces of the insulating cover 6, the insulating cover 6 is connected to the insulating cover 6 from the outer surface of the insulating cover 6 via the first insertion hole 611a and the second insertion hole 611b, as shown in FIG. An electric path 190 up to 150 is formed.

このような状況において、強風による絶縁カバー６の揺動などにより、隣り合う絶縁カバー６同士が図９に示すように接触すると、隣り合う各絶縁カバー６に形成された各電路１９０により短絡することが想定される。 In such a situation, when the adjacent insulating covers 6 come into contact with each other as shown in FIG. 9 due to the swing of the insulating covers 6 due to a strong wind, the electric circuits 190 formed in the adjacent insulating covers 6 cause a short circuit. Is assumed.

本開示は、強風による絶縁カバー６の揺動などにより絶縁カバー同士が接触することによる短絡を抑制する技術を提供する。 The present disclosure provides a technique for suppressing a short circuit caused by contact between insulating covers due to rocking of the insulating cover 6 due to a strong wind or the like.

本開示の一態様は、開閉器（１００）から延設される開閉器リード線（１１００）の端部と高圧縁廻電線（１２００）の端部とが電気的に接続された接続部（１４０ａ，１４０ｂ，１５０）を保護する絶縁カバー（１，２，３）であって、カバー本体（１２０，３２０）と、カバー蓋（１１０，３１０）と、反発部（１２３，２２３，２２４，３２３，３２４，３３０）と、を有する。カバー本体は、接続部を格納する内部空間を形成し、内部空間と外部空間とを連通させる開口面である本体開口面を有する箱状に形成される。カバー蓋は、本体開口面を塞ぐようにカバー本体に着脱され、かつ、開閉器リード線及び高圧縁廻電線を、内部空間に引き込む引込孔が形成される。反発部は、Ｎ極及びＳ極の一方の磁極を指定磁極として、指定磁極がカバー本体の外側を向くような磁界を発生させる。 One aspect of the present disclosure is a connection portion (140a) in which the end portion of the switch lead wire (1100) extending from the switch (100) and the end portion of the high-voltage peripheral wire (1200) are electrically connected. , 140b, 150), which are insulating covers (1, 2, 3), including a cover body (120, 320), a cover lid (110, 310), and a repulsive portion (123, 223, 224, 323). 324,330) and. The cover main body forms an internal space for accommodating the connection portion, and is formed in a box shape having a main body opening surface which is an opening surface for communicating the internal space and the external space. The cover lid is attached to and detached from the cover main body so as to close the opening surface of the main body, and a lead-in hole for drawing the switch lead wire and the high-voltage marginal electric wire into the internal space is formed. The repulsive portion uses one of the north pole and the south pole as the designated magnetic pole, and generates a magnetic field such that the designated magnetic pole faces the outside of the cover body.

このような構成によれば、絶縁カバーの周面の少なくとも一部に外側向きに同じ磁極となる反発部を有する。このため、反発部同士は磁石の斥力により隣り合う絶縁カバーが反発し、絶縁カバー同士の接触が抑制され、その結果、短絡を抑制することができる。 According to such a configuration, at least a part of the peripheral surface of the insulating cover has a repulsive portion having the same magnetic poles facing outward. Therefore, the repulsive forces of the magnets repel the adjacent insulating covers from each other, and the contact between the insulating covers is suppressed, and as a result, a short circuit can be suppressed.

また、本開示の別の一態様は、開閉器（１００）から延設される開閉器リード線（１１００）の端部と高圧縁廻電線（１２００）の端部と電気的に接続された接続部（１４０ａ，１４０ｂ，１５０）を保護する絶縁カバーの周面に着脱可能に取り付けられる接触抑制具（４，５）であって、抑制反発部（４１，４５，５２，５５）と、固定部（４２，４３）と、を備える。抑制反発部は、Ｎ極及びＳ極の一方の磁極を指定磁極として、指定磁極が接触抑制具の外側を向くような磁界を発生させる。固定部は、抑制反発部を絶縁カバーに対してあらかじめ決められた位置に位置するように固定する。 Further, another aspect of the present disclosure is an electrically connected connection between the end of the switch lead wire (1100) extending from the switch (100) and the end of the high-voltage peripheral wire (1200). A contact suppressor (4,5) that is detachably attached to the peripheral surface of the insulating cover that protects the portions (140a, 140b, 150). (42, 43) and. The suppression repulsion portion uses one of the N pole and the S pole as the designated magnetic pole, and generates a magnetic field such that the designated magnetic pole faces the outside of the contact inhibitor. The fixing portion fixes the restraining repulsion portion so as to be located at a predetermined position with respect to the insulating cover.

このような構成によれば、隣り合う絶縁カバーの周面に着脱可能に取り付けられた接触抑制具は反発部を有する。このため、接触抑制具に備えられた反発部同士の磁石の斥力により隣り合う絶縁カバー反発し、絶縁カバー同士の接触が抑制され、その結果、配電線の短絡を抑制することができる。 According to such a configuration, the contact suppressor detachably attached to the peripheral surface of the adjacent insulating cover has a repulsive portion. Therefore, the repulsive force of the magnets between the repulsive portions provided in the contact suppressor repels the adjacent insulating covers, and the contact between the insulating covers is suppressed. As a result, the short circuit of the distribution line can be suppressed.

以下に本発明の例示的な実施形態について図面を参照しながら説明する。
［１．第一実施形態］
［１－１．構成］
第一実施形態（以下、第一実施形態の説明中では、第一実施形態を「本実施形態」ともいう）における絶縁カバー１について図を用いて説明する。 Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.
[1. First Embodiment]
[1-1. Constitution]
The insulation cover 1 in the first embodiment (hereinafter, in the description of the first embodiment, the first embodiment is also referred to as “the present embodiment”) will be described with reference to the drawings.

図１に示すように、絶縁カバー１は、カバー蓋１１０とカバー本体１２０とにより構成される。
カバー本体１２０は、外形が略直方体状で内部空間を有し、一つの面が開口した箱形状に形成される。 As shown in FIG. 1, the insulating cover 1 is composed of a cover lid 110 and a cover main body 120.
The cover body 120 has a substantially rectangular parallelepiped outer shape, has an internal space, and is formed in a box shape with one surface open.

ここで、カバー本体１２０は、開口した面を本体開口面として、本体開口面と対向する面を本体底面とする。そして、カバー本体１２０を構成する本体開口面及び本体底面以外の面を本体側面という。本体側面は、本体開口面を上とし、カバー本体１２０の本体底面を下として、当該側面の左右方向に対して上下方向により長い略長方形状に形成される。また、カバー本体１２０の本体開口面及び本体底面に沿った断面形状は、略長方形で角がない形状に形成される。 Here, in the cover main body 120, the opened surface is the main body opening surface, and the surface facing the main body opening surface is the main body bottom surface. The surfaces other than the opening surface of the main body and the bottom surface of the main body constituting the cover main body 120 are referred to as the side surfaces of the main body. The side surface of the main body is formed in a substantially rectangular shape longer in the vertical direction with respect to the left-right direction of the side surface, with the opening surface of the main body facing up and the bottom surface of the main body 120 facing down. Further, the cross-sectional shape of the cover main body 120 along the main body opening surface and the main body bottom surface is formed to be substantially rectangular and has no corners.

なお、以下では、カバー本体１２０の上下方向と絶縁カバー１及び絶縁カバー１を構成する各構成における上下方向とは同一として説明する。
カバー本体１２０の側面は、一対の対向する面である大側面部１２１及び大側面部１２１に比して面積の小さい一対の対向する面である小側面部１２２により構成される。 In the following, the vertical direction of the cover main body 120 and the vertical direction in each configuration constituting the insulating cover 1 and the insulating cover 1 will be described as the same.
The side surface of the cover body 120 is composed of a pair of facing surfaces, a large side surface portion 121, and a pair of small side surface portions 122 having a smaller area than the large side surface portion 121.

大側面部１２１の一対の対向する面の面内の設置位置にはそれぞれ磁石１２３が埋設される。ここで、設置位置は、カバー本体１２０の上下方向の中央よりも下側に位置する。
磁石１２３の向きは、Ｎ極及びＳ極のうちの一方の磁極を特定磁極として特定磁極がカバー本体１２０の内部空間に対して外側を向くように設置される。例えば、一方の磁石１２３のＮ極が外向きに設置されると、他方の磁石１２３のＮ極も同様に外向きに設置される。 Magnets 123 are embedded in the installation positions of the pair of facing surfaces of the large side surface portion 121 in the plane. Here, the installation position is located below the center of the cover body 120 in the vertical direction.
The direction of the magnet 123 is such that one of the north pole and the south pole is set as a specific magnetic pole and the specific magnetic pole faces the outside with respect to the internal space of the cover main body 120. For example, when the N pole of one magnet 123 is installed outward, the N pole of the other magnet 123 is also installed outward.

カバー蓋１１０は、カバー本体１２０の上側の本体開口面を着脱可能に覆う。
カバー蓋１１０は、第一挿入孔１１１ａと、第二挿入孔１１１ｂと、割面部１１２とを有する。第一挿入孔１１１ａは、開閉器リード線１１００を挿入可能な形状及び大きさに形成される。同様に第二挿入孔１１１ｂは、高圧縁廻電線１２００を挿入可能な形状及び大きさに形成される。また、カバー蓋１１０の第一挿入孔６１１ａと第二挿入孔１１１ｂとの間及び第一挿入孔１１１ａ及び第二挿入孔１１１ｂのそれぞれからカバー蓋１１０の端部にかけて、一直線上にカバー蓋１１０を分割する割面部１１２を有する。この割面部１１２により、開閉器リード線１１００及び高圧縁廻電線１２００が接続された状態で、絶縁カバー６に挿入することができる。 The cover lid 110 detachably covers the opening surface of the main body on the upper side of the cover main body 120.
The cover lid 110 has a first insertion hole 111a, a second insertion hole 111b, and a split surface portion 112. The first insertion hole 111a is formed in a shape and size into which the switch lead wire 1100 can be inserted. Similarly, the second insertion hole 111b is formed in a shape and size into which a high-voltage peripheral electric wire 1200 can be inserted. Further, the cover lid 110 is placed in a straight line between the first insertion hole 611a and the second insertion hole 111b of the cover lid 110 and from each of the first insertion hole 111a and the second insertion hole 111b to the end of the cover lid 110. It has a split surface portion 112 to be divided. The split surface portion 112 allows the switch lead wire 1100 and the high-voltage peripheral electric wire 1200 to be inserted into the insulating cover 6 in a connected state.

なお、開閉器リード線１１００は、図６に示すように、一般的な公共の電線に設置された開閉器１００から延設される導線をいう。また、高圧縁廻電線１２００は、一般的な公共の電柱に設置される電線同士を接続するための引き回しに用いられる電線をいう。 As shown in FIG. 6, the switch lead wire 1100 refers to a conductor wire extending from the switch 100 installed on a general public electric wire. Further, the high-voltage peripheral electric wire 1200 refers to an electric wire used for routing for connecting electric wires installed in general public utility poles.

図７（ｂ）に示す従来技術と同様、カバー蓋１１０とカバー本体１２０とにより構成された絶縁カバー１が有する内部空間において、開閉器リード線１１００の先端の被覆を除いた部分と高圧縁廻電線１２００の先端の被覆を除いた部分がボルト１４０ａ及びナット１４０ｂにより固定されることにより、接続部１５０を構成する。 Similar to the conventional technique shown in FIG. 7B, in the internal space of the insulating cover 1 composed of the cover lid 110 and the cover main body 120, the portion of the switch lead wire 1100 excluding the coating and the high-voltage edge circumference. The portion of the electric wire 1200 excluding the coating is fixed by the bolt 140a and the nut 140b to form the connection portion 150.

［１－２．作用］
本実施形態の絶縁カバー１によれば、この絶縁カバー１を用いて上述した各接続部１５０を覆った場合、各絶縁カバー１には磁石１２３がそれぞれ同じ極である指定磁極が絶縁カバー１の外側を向くように埋設される。これにより、例えば、強風や電柱の揺動などにより複数の絶縁カバー１が揺動し、互いに接近した場合などにも、絶縁カバー１に埋設された磁石１２３同士の斥力により、隣り合う絶縁カバー１の接触を抑制することができる。 [1-2. Action]
According to the insulating cover 1 of the present embodiment, when the above-mentioned connection portions 150 are covered with the insulating cover 1, each insulating cover 1 has a designated magnetic pole in which the magnet 123 has the same pole. It is buried facing outward. As a result, even when a plurality of insulating covers 1 swing due to strong winds or swings of utility poles and come close to each other, the insulating covers 1 adjacent to each other due to the repulsive force of the magnets 123 embedded in the insulating cover 1 Contact can be suppressed.

［１－３．効果］
（１）本実施形態の絶縁カバー１によれば、塩やホコリ等の汚れが絶縁カバーの内部の接続部１５０及び外表面に付着し、電路１９０が絶縁カバー１形成されたとしても、隣り合う絶縁カバー１に埋設された磁石１２３の斥力により、絶縁カバー１同士の接触が抑制され、その結果、絶縁カバー１同士の接触による配電線の短絡を抑制することができる。 [1-3. effect]
(1) According to the insulating cover 1 of the present embodiment, even if dirt such as salt and dust adheres to the connection portion 150 inside the insulating cover and the outer surface, and the electric circuit 190 is formed on the insulating cover 1, they are adjacent to each other. The repulsive force of the magnet 123 embedded in the insulating cover 1 suppresses the contact between the insulating covers 1 and, as a result, the short circuit of the distribution wire due to the contact between the insulating covers 1 can be suppressed.

（２）本実施形態の絶縁カバー１によれば、絶縁カバー１は、開閉器リード線１１００と高圧縁廻電線１２００との接続部分に取り付けられた状態で吊持される。そして、絶縁カバー１において磁石１２３が埋設される位置である設置位置は、カバー本体１２０の上下方向の中央よりも下側に位置する。 (2) According to the insulating cover 1 of the present embodiment, the insulating cover 1 is suspended while being attached to the connection portion between the switch lead wire 1100 and the high-voltage peripheral electric wire 1200. The installation position where the magnet 123 is embedded in the insulating cover 1 is located below the center of the cover body 120 in the vertical direction.

これにより、磁石１２３が埋設される位置がカバー本体１２０の上下方向の中央よりも上側に位置する場合に比べ、絶縁カバー１が揺動した際に接近しやすい位置に磁石１２３の設置位置が位置するため、磁石１２３同士の斥力を効率よく働かせることができる。 As a result, the installation position of the magnet 123 is positioned at a position that is easily accessible when the insulating cover 1 swings, as compared with the case where the position where the magnet 123 is embedded is located above the center in the vertical direction of the cover main body 120. Therefore, the repulsive force between the magnets 123 can be efficiently applied.

[１－４．第一実施形態の変形例]
（１）上述した実施形態では、磁石１２３は、カバー本体１２０の大側面部１２１に埋め込まれるが、磁石は、大側面部１２１に埋め込まれるものに限定されるものではない。 [1-4. Modification example of the first embodiment]
(1) In the above-described embodiment, the magnet 123 is embedded in the large side surface portion 121 of the cover main body 120, but the magnet is not limited to the one embedded in the large side surface portion 121.

例えば、図２に示す絶縁カバー２のように、磁石が埋め込まれる位置に相当する位置に大側面部２２１の外面から突出する枠体である保持部２２４を備え、保持部２２４に磁石２２３が嵌め込まれるような形態であってもよい。 For example, as in the insulating cover 2 shown in FIG. 2, a holding portion 224, which is a frame body protruding from the outer surface of the large side surface portion 221 is provided at a position corresponding to a position where the magnet is embedded, and the magnet 223 is fitted in the holding portion 224. It may be in such a form.

（２）また、図３に示す絶縁カバー３のように、大側面部１２１の上下方向に延びるレール部３２４を備えてもよい。レール部３２４は、Ｌ字型の断面を有し、当該Ｌ字型の断面形状と大側面部１２１とで挟み込むようにして、レールの延びた方向に板状の磁石３２３を摺動可能に保持してもよい。そして、レール部３２４のレールの下端部分には、磁石３２３がレールから脱落することを阻止するレール保持部３３０を備えてもよい。また、レール部３２４のレールの上端部分は、磁石３２３をレール部３２４に挿入できるように開放されていてもよい。また、カバー蓋３１０には、カバー蓋３１０をカバー本体３２０に取り付けた状態においてレール部３２４の上端部に対応する位置に位置するような突出部３４０を備えてもよい。突出部３４０は、例えば、カバー蓋３１０から下方向にあらかじめ決められた突出位置まで、突出した形状に形成されてもよい。突出位置は、例えば、レール部３２４のレールの上端からレールに磁石を備えた際の上下方向の長さ分だけ離れた位置など、レール部３２４のレールから磁石３２３が脱落することが抑制できる位置であればよい。 (2) Further, as in the insulating cover 3 shown in FIG. 3, a rail portion 324 extending in the vertical direction of the large side surface portion 121 may be provided. The rail portion 324 has an L-shaped cross section, and the plate-shaped magnet 323 is slidably held in the extending direction of the rail so as to be sandwiched between the L-shaped cross-sectional shape and the large side surface portion 121. You may. Then, the lower end portion of the rail of the rail portion 324 may be provided with a rail holding portion 330 that prevents the magnet 323 from falling off the rail. Further, the upper end portion of the rail of the rail portion 324 may be open so that the magnet 323 can be inserted into the rail portion 324. Further, the cover lid 310 may be provided with a protruding portion 340 such that the cover lid 310 is located at a position corresponding to the upper end portion of the rail portion 324 in a state where the cover lid 310 is attached to the cover main body 320. The protruding portion 340 may be formed in a protruding shape, for example, from the cover lid 310 to a predetermined protruding position in the downward direction. The protruding position is, for example, a position separated from the upper end of the rail of the rail portion 324 by the length in the vertical direction when the magnet is provided on the rail, or a position where the magnet 323 can be suppressed from falling off from the rail of the rail portion 324. It should be.

また、このような形状に形成されることにより、カバー蓋３１０をカバー本体３２０から取り外した際に、容易にレール部３２４から磁石３２３を取り外すことができる。
（３）なお、レール部３２４は上下方向に延びるものに限定されるものではなく、横方向に延びるものであってもよい。すなわち、レール部３２４により磁石３２３が摺動する一方向である摺動方向は、上下方向に限定されるものではなく、横方向であってもよい。 Further, by being formed in such a shape, when the cover lid 310 is removed from the cover main body 320, the magnet 323 can be easily removed from the rail portion 324.
(3) The rail portion 324 is not limited to the one extending in the vertical direction, and may be the one extending in the lateral direction. That is, the sliding direction, which is one direction in which the magnet 323 is slid by the rail portion 324, is not limited to the vertical direction, but may be the lateral direction.

この場合、横方向のレールの端部に磁石３２３の脱落を防ぐような突出部があってもよい。
なお、磁石１２３，２２３，３２３、保持部２２４、レール部３２４が反発部に相当する。 In this case, there may be a protrusion at the end of the rail in the lateral direction to prevent the magnet 323 from falling off.
The magnets 123, 223, 323, the holding portion 224, and the rail portion 324 correspond to the repulsive portions.

（４）上記実施形態では、カバー本体１２０は、外形が略直方体状の箱形形状であり、箱形状の側面部分は、縦長の角のない曲面形状に形成されるとしたが、カバー本体１２０はこのような形状に限定されるものではない。例えば、側面が平面により構成される直方体であってもよく、有底円筒状に構成されてもよい。 (4) In the above embodiment, the cover main body 120 has a box shape having a substantially rectangular parallelepiped outer shape, and the side surface portion of the box shape is formed into a curved surface shape having no vertically long corners. Is not limited to such a shape. For example, the side surface may be a rectangular parallelepiped formed of a flat surface, or may be formed in a bottomed cylindrical shape.

［２．第二実施形態］
［２－１．構成］
第二実施形態（以下、第二実施形態の説明中では、第二実施形態を「本実施形態」という）は、従来の絶縁カバー６に着脱可能に取り付ける接触抑制具４である。 [2. Second embodiment]
[2-1. Constitution]
The second embodiment (hereinafter, in the description of the second embodiment, the second embodiment is referred to as “the present embodiment”) is a contact inhibitor 4 detachably attached to the conventional insulating cover 6.

すなわち、第一実施形態では、絶縁カバーそのものに磁石が配置されたが、第二実施形態では、図４に示すように、絶縁カバー６に対して着脱可能である接触抑制具４を介して磁石４５が絶縁カバー６に取り付けられる点で相違する。 That is, in the first embodiment, the magnet is arranged on the insulating cover itself, but in the second embodiment, as shown in FIG. 4, the magnet is interposed via the contact inhibitor 4 which is removable from the insulating cover 6. The difference is that 45 is attached to the insulating cover 6.

なお、接触抑制具４は、例えば、ゴムやプラスチックなどの絶縁材により形成される。
本実施形態で使用される絶縁カバーは従来技術における絶縁カバー６に接触抑制具４が設置される場合について説明する。 The contact inhibitor 4 is formed of, for example, an insulating material such as rubber or plastic.
As the insulating cover used in the present embodiment, a case where the contact inhibitor 4 is installed on the insulating cover 6 in the prior art will be described.

なお、絶縁カバー６の各構成は、磁石が埋め込まれていない以外は絶縁カバー１の各構成と同様であるとして、以下説明する。
接触抑制具４は、絶縁カバー６の形状に沿った形状に形成される。 It should be noted that each configuration of the insulating cover 6 is the same as each configuration of the insulating cover 1 except that the magnet is not embedded, and will be described below.
The contact inhibitor 4 is formed in a shape that follows the shape of the insulating cover 6.

接触抑制具４は、抑制具保持部４１、挟持部４２及び係合部４３を備える。
抑制具保持部４１は、磁石４５を保持する形状に形成される。
挟持部４２は、抑制具保持部４１と接合され、蝶番４２１と締込部４２２と一対の周面板４２３とを備える。 The contact restraining tool 4 includes a restraining tool holding portion 41, a holding portion 42, and an engaging portion 43.

The hinge 421, the tightening portion 422, and the peripheral plate 423 are each formed in a shape that conforms to the shape of the cover main body 620.

蝶番４２１は、一対の周面板４２３の一端に設けられ、一対の周面板４２３を繋いでいる軸を回転軸として回動可能に接合する。
締込部４２２は、一対の周面板４２３の他端側、すなわち、一対の周面板４２３の蝶番４２１が設けられていない端に設けられる。 The hinge 421 is provided at one end of a pair of peripheral plates 423, and is rotatably joined with an axis connecting the pair of peripheral plates 423 as a rotation axis.
The tightening portion 422 is provided on the other end side of the pair of peripheral plates 423, that is, at the end of the pair of peripheral plates 423 where the hinge 421 is not provided.

締込部４２２は、周面板４２３を閉じた状態に固定する機構を有する。締込部４２２は、例えば、一対の周面板４２３から延出され、あらかじめ決められた径のボルトを挿通させるような大きさ及び形状の穴が設けられ、当該穴をボルトとナットで固定することにより周面板４２３を閉じた状態で固定するネジ締結機構であってもよい。また、締込部４２２は、一対の周面板４２３から延出され、一方に開口を備え、他方に当該開口を挿通する凸部を備え、凸部が開口を挿通し、凸部の端部が開口に引っかかるようにすることにより、周面板４２３を閉じた状態で固定するスナップフィットであってもよい。 The tightening portion 422 has a mechanism for fixing the peripheral plate 423 in a closed state. The tightening portion 422 is provided with, for example, a hole extending from a pair of peripheral plates 423 and having a size and shape for inserting a bolt having a predetermined diameter, and the hole is fixed with a bolt and a nut.

係合部４３は、係合板４３１と引掛部４３２とを備える。
係合部４３は、係合板４３１及び引掛部４３２により、抑制具保持部４１をカバー蓋６１０に係合する。 The engaging portion 43 includes an engaging plate 431 and a hooking portion 432.
The engaging portion 43 engages the restraining tool holding portion 41 with the cover lid 610 by the engaging plate 431 and the hooking portion 432.

係合板４３１は、抑制具保持部４１と接合され、カバー本体６２０の大側面部６２１において磁石４５を設置させる位置から、カバー蓋６１０の蓋の上側まで、大側面部６２１の形状に沿って上下方向に延びる板状部分である。 The engaging plate 431 is joined to the restraining tool holding portion 41, and moves up and down along the shape of the large side surface portion 621 from the position where the magnet 45 is installed on the large side surface portion 621 of the cover main body 620 to the upper side of the cover of the cover lid 610. It is a plate-shaped part that extends in the direction.

係合板４３１は、抑制具保持部４１と接合する側と反対側の端面の中央部分に切欠部４３１ａを有する。切欠部４３１ａは、カバー蓋６１０から突出した突出部６４０の横幅、すなわち、突出部６４０のカバー蓋６１０の大側面部６２１と接する部位の縁に沿った方向の突出部６４０の幅よりも大きく形成される。 The engaging plate 431 has a notch 431a in the central portion of the end surface on the side opposite to the side to be joined to the restraint holding portion 41. The notch 431a is formed to be larger than the width of the protrusion 640 protruding from the cover lid 610, that is, the width of the protrusion 640 in the direction along the edge of the portion of the protrusion 640 in contact with the large side surface portion 621 of the cover lid 610. Will be done.

引掛部４３２は、係合板４３１の切欠部４３１ａが形成されていない部分の上端にカバー本体６２０の内側に向かって突出した形状に形成される。上述した切欠部４３１ａにより、係合板４３１はカバー蓋６１０が有する突出部６４０と接触することなく、引掛部４３２がカバー蓋６１０に引っかけられることにより、接触抑制具４はずり落ちることなく、接触抑制具４を絶縁カバー６に係合する。 The hook portion 432 is formed in a shape protruding inward of the cover main body 620 at the upper end of the portion where the notch portion 431a of the engagement plate 431 is not formed. Due to the notch 431a described above, the engagement plate 431 does not come into contact with the protrusion 640 of the cover lid 610, and the hooking portion 432 is hooked on the cover lid 610, so that the contact inhibitor 4 does not fall off and the contact inhibitor 4 does not come off. 4 is engaged with the insulating cover 6.

［２－２．作用］
以上のように構成された接触抑制具４を絶縁カバー６に係合及び挟持させ、接触抑制具４の抑制具保持部４１に特定磁極が絶縁カバーからみて外側を向くように保持させることにより、絶縁カバー１における大側面部１２１の磁石１２３が配置される位置である設置位置に相当する位置に、磁石４５を配置することができる。 [2-2. Action]

In some cases, the configuration may include only one.

（４）上記実施形態では、接触抑制具４は、上述したような挟持部４２及び係合部４３を備え、挟持部４２及び係合部４３により絶縁カバー６に固定されるが、接触抑制具４の絶縁カバー６への固定はこのような方法によるものに限られず、例えば接触抑制具４は内部空間を有する筒状に形成され、絶縁カバー６を当該筒状の内部空間に格納することにより、絶縁カバー６を固定してもよい。 (4) In the above embodiment, the contact inhibitor 4 includes the holding portion 42 and the engaging portion 43 as described above, and is fixed to the insulating cover 6 by the holding portion 42 and the engaging portion 43. The fixing of 4 to the insulating cover 6 is not limited to such a method. For example, the contact inhibitor 4 is formed in a tubular shape having an internal space, and the insulating cover 6 is stored in the tubular internal space. , The insulating cover 6 may be fixed.

なお、抑制具保持部４１、５２及び磁石４５、５５が抑制反発部に相当する
［３．他の実施形態］
（１）上記第一実施形態及び第二実施形態では、大側面部に設置される磁石の向きは、同じ磁極が外側を向くように設置されるとしたが、大側面部に設置される磁石の向きはこのような方向に限定されるものではない。例えば、絶縁カバー１と隣接する他の絶縁カバー１との間で、接近する磁石の外側の磁極が互いに同極となるように設置されていればよい。すなわち、絶縁カバー１と他の絶縁カバー１との間で、磁力による斥力が生じるように設置されていればよい。 The restraint holding portions 41 and 52 and the magnets 45 and 55 correspond to the restraining repulsion portions [3. Other embodiments]
