Let

プラグ差込部１３は、例えば耐トラッキング及び耐熱性に優れるユリア樹脂等の硬質樹脂材料によって後面が開口した箱状に形成された樹脂成形品から成り、その上壁部には一対の栓刃挿通孔１３ａが上下方向に貫設されている。また、プラグ差込部１３の上壁部には、栓刃挿通孔１３ａを囲繞するとともにプラグ差込部１３と開口部１２の縁部との間に介在する第２のパッキン１３ｂが一体成形されている。 The plug insertion portion 13 is formed of a resin molded product formed in a box shape whose rear surface is opened by a hard resin material such as urea resin having excellent tracking resistance and heat resistance, for example, and a pair of plug blade insertion holes are provided on the upper wall portion thereof. The hole 13a is penetrated in the up-down direction. A second packing 13b that surrounds the plug blade insertion hole 13a and is interposed between the plug insertion portion 13 and the edge of the opening 12 is integrally formed on the upper wall portion of the plug insertion portion 13. ing.

第２のパッキン１３ｂは、ゴムやエラストマー等の復元性（弾性）を有する軟質樹脂材料を用いた樹脂成形品から成り、その下端部には全周に亘ってフランジが一体に形成されている。而して、プラグ差込部１３を外カバー１１の開口部１２に取り付ける際に、第２のパッキン１３ｂのフランジが筐体１の内部において開口部１２の内周縁と密着し、開口部１２から筐体１内部に水が浸入するのを防いでいる。また、第２のパッキン１３ｂの上端部は、プラグ差込部１３の上面よりも上方へと突出するとともに、その外形がプラグにおける栓刃が突設されている面の外形に収まるように形成されている。このため、栓刃挿入孔１３ａを介してプラグの栓刃を刃受部に接触接続した際には、プラグにおける栓刃が突設している面、即ちプラグにおける筐体１との対向面に第２のパッキン部１３ｂの上端部が密着することになる。この時、第２のパッキン部１３ｂは上述したように復元性（弾性）を有しているので、プラグ差込部１３とプラグとの間で押し縮められるように変形してプラグに密着することで、プラグと筐体１との隙間を無くすことができ、栓刃を水や埃から保護し、トラッキングや短絡等が生じるのを防ぐことができる。 The second packing 13b is formed of a resin molded product using a soft resin material having resilience (elasticity) such as rubber or elastomer, and a flange is integrally formed at the lower end portion over the entire circumference. Thus, when the plug insertion portion 13 is attached to the opening portion 12 of the outer cover 11, the flange of the second packing 13 b is in close contact with the inner peripheral edge of the opening portion 12 inside the housing 1. Water is prevented from entering the housing 1. The upper end portion of the second packing 13b protrudes upward from the upper surface of the plug insertion portion 13, and the outer shape thereof is formed so as to fit within the outer shape of the surface of the plug on which the plug blade protrudes. ing. For this reason, when the plug blade of the plug is contact-connected to the blade receiving portion through the plug blade insertion hole 13a, the surface of the plug on which the plug blade protrudes, that is, the surface of the plug facing the housing 1 is provided. The upper end part of the 2nd packing part 13b will closely_contact | adhere. At this time, since the second packing portion 13b has resilience (elasticity) as described above, the second packing portion 13b is deformed so as to be compressed between the plug insertion portion 13 and the plug and is in close contact with the plug. Thus, the gap between the plug and the housing 1 can be eliminated, the plug blade can be protected from water and dust, and tracking and short-circuiting can be prevented.

Inside the handle 5, a series circuit of a light emitting element LD and a resistor R, which will be described later, and a handle body 50 for holding the series circuit are housed. A substantially cylindrical tube portion 50a having an inner diameter approximately the same as the interval between arm portions 7b of the opening / closing element 7 described later is formed in a substantially central position on the lower surface of the handle body 50 so as to protrude downward. Further, shaft projections 50b projecting outward are formed at substantially the center in the left-right direction of the front wall and the rear wall of the handle body 50, respectively.

ハンドル５の上壁には、ハンドル５とほぼ同寸法に形成された第１のパッキン５１が覆設されている。第１のパッキン５１は、ゴムやエラストマー等の復元性（弾性）を有する軟質樹脂材料を用いた樹脂成形品から成り、その下端部には全周に亘ってフランジが一体に形成されている。而して、第１のパッキン５１をハンドル５に覆設した状態でハンドル５を外カバー１１の開口部１２に取り付けることで、第１のパッキン５１のフランジが筐体１の内部において開口部１２の内周縁と密着し、開口部１２から筐体１内部に水が浸入するのを防いでいる。 A first packing 51 is formed on the upper wall of the handle 5 so as to have substantially the same dimensions as the handle 5. The first packing 51 is formed of a resin molded product using a soft resin material having resilience (elasticity) such as rubber or elastomer, and a flange is integrally formed at the lower end thereof over the entire circumference. Thus, by attaching the handle 5 to the opening 12 of the outer cover 11 in a state where the first packing 51 is covered with the handle 5, the flange of the first packing 51 is opened inside the housing 1. In close contact with the inner peripheral edge, water is prevented from entering the housing 1 from the opening 12.

ハウジング６は、例えば合成樹脂成形品から成り上下に開口した角筒形状のカバー６０と、例えば合成樹脂成形品から成りカバー６０に機械的に結合してカバー６０の下側の開口を閉塞するベース６１とから成る。カバー６０の上端部において左右方向の略中央には、前後の壁にそれぞれ略円形状の軸受穴６０ａが貫設されており、ハンドル用ボディ５０の軸突起５０ｂが軸受穴６０ａに挿入されることによってハンドル５がカバー６０に揺動自在に枢着される。 The housing 6 includes a rectangular tube-shaped cover 60 made of, for example, a synthetic resin molded product and an upper and lower opening, and a base that is made of, for example, a synthetic resin molded product and mechanically coupled to the cover 60 and closes the lower opening of the cover 60. 61. A substantially circular bearing hole 60a is provided in the front and rear walls at the upper center of the cover 60 in the left-right direction, and the shaft protrusion 50b of the handle body 50 is inserted into the bearing hole 60a. As a result, the handle 5 is pivotally attached to the cover 60 in a swingable manner.

ハウジング６内部には、金属板から成り厚み方向を上下方向と一致させて突部２ｇの上に載置される本体部７ａと、本体部７ａの左右両端縁からそれぞれ上方へ向かって突設された腕部７ｂとから成る断面略コ字状の開閉子７が収納されている。開閉子７の左側の腕部７ｂの左面には可動接点７ｃが設けられている。ここで、前述の端子板３には、固定接点３ａを保持する接点保持部３１が一体に形成されており、可動接点７ｃに対向する位置に固定接点３ａが配置される。 Inside the housing 6, a main body portion 7 a made of a metal plate and placed on the protrusion 2 g with the thickness direction coincided with the vertical direction, and protrudes upward from both left and right edges of the main body portion 7 a. An opening / closing element 7 having a substantially U-shaped cross-section composed of the arm portion 7b is accommodated. A movable contact 7 c is provided on the left surface of the left arm portion 7 b of the switch 7. Here, the above-mentioned terminal plate 3 is integrally formed with a contact holding portion 31 for holding the fixed contact 3a, and the fixed contact 3a is disposed at a position facing the movable contact 7c.

ハンドル用ボディ５０の筒部５０ａには、開閉子７の腕部７ｂの間隔よりも僅かに小さい外形を有するコイルばねから成る反転ばね７ｄの一端が収納される。反転ばね７ｄは、その他端が開閉子７の腕部７ｂに挟持されることにより、ハンドル５と開閉子７とにそれぞれ機械的に結合している。カバー６０の内面には、ハウジング６内部の空間を上下に仕切る仕切り壁６０ｂが設けられており、ハンドル用ボディ５０の後面が仕切り壁６０ｂに当接することによってハンドル５の動作範囲が制限されている。また、仕切り壁６０ｂの略中央部には、反転ばね７ｄが挿通されるばね挿通穴６０ｃが上下に貫設されている。 One end of a reversing spring 7d made of a coil spring having an outer shape slightly smaller than the interval between the arm portions 7b of the opening / closing element 7 is accommodated in the cylindrical portion 50a of the handle body 50. The other end of the reversing spring 7d is mechanically coupled to the handle 5 and the opening / closing element 7 by being sandwiched between the arms 7b of the opening / closing element 7. A partition wall 60b for vertically partitioning the space inside the housing 6 is provided on the inner surface of the cover 60, and the operating range of the handle 5 is limited by the rear surface of the handle body 50 coming into contact with the partition wall 60b. . In addition, a spring insertion hole 60c through which the reversing spring 7d is inserted is vertically provided at a substantially central portion of the partition wall 60b.

以下、スイッチＳＷのスイッチ機構について説明する。反転ばね７ｄは、常に圧縮された状態に維持されており、開閉子７が突部２ｇ上で左右の何れに倒れているかに応じて、その上下方向の中央部を左又は右に突出させるように曲がった姿勢で安定するようになっている。反転ばね７ｄが中央部を左方へ突出させるように曲がった状態では、ハンドル５は右側に倒れた姿勢となり、開閉子７は左側に倒れた姿勢となる。この状態では、可動接点７ｃは固定接点３ａに接触しており、第２の刃受部２ｂと端子板３とが電気的に接続され、外部電源から第２の刃受部２ｂへの通電がオンとなっている。一方、反転ばね７ｄが中央部を右方へ突出させるように曲がった状態では、ハンドル５は左側に倒れた姿勢となり、開閉子７は右側に倒れた姿勢となる。この状態では、可動接点７ｃは固定接点３ａから離れており、第２の刃受部２ｂと端子板３とが電気的に接続されず、外部電源から第２の刃受部２ｂへの通電がオフとなっている。尚、反転ばね７ｄの前記各状態は、反転ばね７ｄのばね力によって維持される。 Hereinafter, the switch mechanism of the switch SW will be described. The reversing spring 7d is always maintained in a compressed state so that the center portion in the vertical direction protrudes to the left or right depending on whether the switch 7 is tilted to the left or right on the protrusion 2g. It is designed to stabilize with a bent posture. In a state in which the reversing spring 7d is bent so that the central portion protrudes to the left, the handle 5 is in the posture of being tilted to the right, and the switch 7 is in the posture of being tilted to the left. In this state, the movable contact 7c is in contact with the fixed contact 3a, the second blade receiving portion 2b and the terminal plate 3 are electrically connected, and energization from the external power source to the second blade receiving portion 2b is performed. Is on. On the other hand, in a state in which the reversing spring 7d is bent so that the central portion protrudes to the right, the handle 5 is in a posture that falls to the left, and the switch 7 is in a posture that falls to the right. In this state, the movable contact 7c is separated from the fixed contact 3a, the second blade receiving portion 2b and the terminal plate 3 are not electrically connected, and the second blade receiving portion 2b is energized from the external power source. It is off. Each state of the reversing spring 7d is maintained by the spring force of the reversing spring 7d.

ここで、例えばハンドル５が右側に倒れている状態において、ハンドル５の左端部を反転ばね７ｄのばね力に抗って下方へ押操作すると、反転ばね７ｄが最も圧縮される状態を超えて反転した時に、反転ばね７ｄのばね力によってハンドル５は左側に倒れた姿勢となり、外部電源から第２の刃受部２ｂへの通電がオンからオフに切り替えられる。また、この状態からハンドル５の右端部を反転ばね７ｄのばね力に抗って下方に押操作すれば、反転ばね７ｄのばね力によってハンドル５は右側に倒れた姿勢となり、外部電源から第２の刃受部２ｂへの通電がオフからオンに切り替えられる。 Here, for example, when the handle 5 is tilted to the right and the left end of the handle 5 is pushed downward against the spring force of the reversing spring 7d, the reversing spring 7d is reversed beyond the most compressed state. At this time, the handle 5 is tilted to the left side by the spring force of the reversing spring 7d, and energization from the external power source to the second blade receiving portion 2b is switched from on to off. Further, if the right end portion of the handle 5 is pushed downward against the spring force of the reversing spring 7d from this state, the handle 5 is tilted to the right side by the spring force of the reversing spring 7d, and the second power is supplied from the external power source. The energization of the blade receiving portion 2b is switched from off to on.

更に、ハンドル５には、例えばネオン管のような発光素子ＬＤ及び抵抗Ｒの直列回路が収納されている。発光素子ＬＤ及び抵抗Ｒの直列回路の一端は、反転ばね７ｄと開閉子７とを介して第２の刃受部２ｂに電気的に接続され、他端は、軸方向が上下方向に沿ったコイルばねから成る導電ばね２ｅを介して第１の刃受部２ａに接続されている。即ち、発光素子ＬＤは、外部電源から第２の刃受部２ｂへの通電がオンの状態で給電されて点灯する。尚、導電ばね２ｅは、その下端部を導電板２の左右方向に沿って等間隔に設けられて上方に突出するばね受け突起２ｆにそれぞれ挿入される。また、カバー６０の仕切り壁６０ｂには、ばね挿通穴６０ｃの右側において仕切り壁６０ｂの上下に連通して導電ばね２ｅが挿通される筒状の導電ばね挿通部６０ｄが設けられている。 Furthermore, the handle 5 houses a series circuit of a light emitting element LD such as a neon tube and a resistor R, for example. One end of the series circuit of the light emitting element LD and the resistor R is electrically connected to the second blade receiving portion 2b via the reversing spring 7d and the opening / closing element 7, and the other end of the series circuit has an axial direction along the vertical direction. It is connected to the first blade receiving portion 2a via a conductive spring 2e made of a coil spring. That is, the light emitting element LD is lit by being supplied with power from the external power supply to the second blade receiving portion 2b in an on state. The conductive springs 2e are respectively inserted into spring receiving protrusions 2f that are provided at equal intervals along the left-right direction of the conductive plate 2 and protrude upward. The partition wall 60b of the cover 60 is provided with a cylindrical conductive spring insertion portion 60d that is connected to the upper and lower sides of the partition wall 60b on the right side of the spring insertion hole 60c and into which the conductive spring 2e is inserted.

前記各刃受部は、図１に示すように、それぞれ外ボディ１０の左右方向に沿って複数個（図示では３つ）並設された中ボディ４内に保持される。中ボディ４は、例えば上面を開口した略箱体に形成された合成樹脂成形品から成り、その左右方向の略中央には、第１の刃受部２ａと第２の刃受部２ｂとを機械的且つ電気的に隔てる隔壁４０が突設されている。また、前壁部には、第１の刃受部２ａ及び第２の刃受部２ｂを各々内部に挿通するための２つの挿通部４１が左右方向に沿って貫設されている。 As shown in FIG. 1, each of the blade receiving portions is held in a plurality of (three in the drawing) middle bodies 4 arranged in parallel along the left-right direction of the outer body 10. The middle body 4 is made of, for example, a synthetic resin molded product formed in a substantially box shape having an upper surface opened, and a first blade receiving portion 2a and a second blade receiving portion 2b are provided at substantially the center in the left-right direction. A partition wall 40 is provided so as to be separated mechanically and electrically. In addition, two insertion portions 41 for penetrating the first blade receiving portion 2a and the second blade receiving portion 2b respectively into the front wall portion are provided in the left-right direction.

ここで、中ボディ４に第１の刃受部２ａ及び第２の刃受部２ｂを収納した際に、延設片２０，２２に各々設けられた押さえ部２ｃが中ボディ４の外側に配置される（図３（ａ）〜（ｃ）参照）。押さえ部２ｃは、図３（ｂ）に示すように、プラグ差込部１３と外ボディ１０との間に配設され、第１の刃受部２ａ及び第２の刃受部２ｂの上下方向の移動を規制する。而して、プラグの栓刃の挿抜時に、挿抜に伴って第１の刃受部２ａ及び第２の刃受部２ｂが移動するのを防ぐことができる。また、押さえ部２ｃが中ボディ４の外側に配設されるので、第１の刃受部２ａ及び第２の刃受部２ｂと押さえ部２ｃとの間が中ボディ４の前壁部によって隔てられる。而して、プラグの栓刃の挿抜に伴って第１の刃受部２ａ及び第２の刃受部２ｂから生じる金属粉が押さえ部２ｃの方に飛散するのを防ぐことができ、隣り合う押さえ部２ｃ間が短絡するのを防止することができる。 Here, when the first blade receiving portion 2 a and the second blade receiving portion 2 b are stored in the middle body 4, the holding portions 2 c provided on the extended pieces 20 and 22 are arranged outside the middle body 4. (See FIGS. 3A to 3C). As shown in FIG. 3 (b), the pressing portion 2c is disposed between the plug insertion portion 13 and the outer body 10, and the vertical direction of the first blade receiving portion 2a and the second blade receiving portion 2b. Regulate the movement of Thus, when the plug blade of the plug is inserted / removed, the first blade receiving portion 2a and the second blade receiving portion 2b can be prevented from moving along with the insertion / removal. Moreover, since the holding | suppressing part 2c is arrange | positioned on the outer side of the inside body 4, between the 1st blade receiving part 2a and the 2nd blade receiving part 2b, and the holding | suppressing part 2c is separated by the front wall part of the inside body 4. It is done. Thus, it is possible to prevent the metal powder generated from the first blade receiving portion 2a and the second blade receiving portion 2b from being scattered toward the holding portion 2c as the plug blade is inserted and removed, and adjacent to each other. It is possible to prevent a short circuit between the pressing portions 2c.

また、中ボディ４に第１の刃受部２ａ及び第２の刃受部２ｂを収納する際に、図５（ａ）〜（ｃ）に示すように、押さえ部２ｃと一体に設けられた位置決め用突起２ｄを外ボディ１０に設けられた嵌合凹所１０ｆに嵌合することで、押さえ部２ｃを筐体１内部に位置決めすることができる。ここで、例えば押さえ部２ｃが変形している場合には、位置決め用突起２ｄを嵌合凹所１０ｆに嵌合することができないので、押さえ部２ｃが変形した刃受部を誤って収納するのを防ぐことができる。また、押さえ部２ｃの変形が利用可能な程度の変形であれば、嵌合凹所１０ｆに位置決め用突起２ｄを強制的に挿入することで押さえ部２ｃの変形を矯正することができる。 Further, when the first blade receiving portion 2a and the second blade receiving portion 2b are accommodated in the middle body 4, as shown in FIGS. 5A to 5C, the holding portion 2c is provided integrally. By fitting the positioning protrusion 2 d into the fitting recess 10 f provided in the outer body 10, the pressing portion 2 c can be positioned inside the housing 1. Here, for example, when the pressing portion 2c is deformed, the positioning projection 2d cannot be fitted into the fitting recess 10f, so that the blade receiving portion in which the pressing portion 2c is deformed is erroneously stored. Can be prevented. Moreover, if the deformation | transformation of the press part 2c is a deformation | transformation of the level which can be utilized, the deformation | transformation of the press part 2c can be corrected by forcibly inserting the positioning protrusion 2d into the fitting recess 10f.

上述のように、各刃受部を個別に保持する中ボディ４を外ボディ１０の左右方向に沿って複数個並設したので、全ての刃受部を１個の中ボディ４で保持する場合と比較して、中ボディ４の長手方向の寸法を小さくすることができる。したがって、中ボディ４の上下方向における反りが低減されるので、外カバー１１及び外ボディ１０が中ボディ４の反りによって押されることがなく、外カバー１１と外ボディ１０との間に隙間が生じるのを防ぐことができ、筐体１内部に水が浸入するのを防ぐことができる。また、スイッチＳＷのハウジング６を外ボディ１０の左右方向に沿って複数個並設したので、全てのスイッチＳＷを１個のハウジング６で保持する場合と比較して、ハウジング６の長手方向の寸法を小さくできる。このため、スイッチＳＷのハウジング６においても前記と同様の効果を奏することが可能である。尚、本実施形態ではプラグ差込部１３及び刃受部が３組であるが、プラグ差込部１３及び刃受部の個数を増やしても同様の効果を奏することが可能である。 As described above, since a plurality of the middle bodies 4 that individually hold the respective blade receiving portions are arranged along the left-right direction of the outer body 10, when all the blade receiving portions are held by one middle body 4 As compared with the above, the longitudinal dimension of the middle body 4 can be reduced. Accordingly, since the warp in the vertical direction of the middle body 4 is reduced, the outer cover 11 and the outer body 10 are not pushed by the warp of the middle body 4, and a gap is generated between the outer cover 11 and the outer body 10. Can be prevented, and water can be prevented from entering the housing 1. Further, since a plurality of the housings 6 of the switch SW are arranged side by side along the left-right direction of the outer body 10, the dimensions of the housing 6 in the longitudinal direction are compared with the case where all the switches SW are held by one housing 6. Can be reduced. For this reason, the same effect as described above can be obtained in the housing 6 of the switch SW. In the present embodiment, there are three sets of plug insertion portions 13 and blade receiving portions. However, the same effect can be obtained even if the number of plug insertion portions 13 and blade receiving portions is increased.

ところで、本実施形態では中ボディ４の外側に押さえ部２ｃが配設されているが、図４（ａ）〜（ｃ）に示すように、押さえ部２ｃを中ボディ４の内側に配設するようにしても構わない。この場合、押さえ部２ｃが第１の刃受部２ａ及び第２の刃受部２ｂの近傍に配設されるので、プラグの栓刃の挿抜時に、挿抜に伴って第１の刃受部２ａ及び第２の刃受部２ｂが移動するのをより確実に防ぐことができる。 By the way, in this embodiment, although the holding | suppressing part 2c is arrange | positioned on the outer side of the middle body 4, as shown to Fig.4 (a)-(c), the holding | suppressing part 2c is arrange | positioned inside the middle body 4. FIG. It doesn't matter if you do. In this case, since the holding | suppressing part 2c is arrange | positioned in the vicinity of the 1st blade receiving part 2a and the 2nd blade receiving part 2b, the 1st blade receiving part 2a is attached with insertion / extraction at the time of insertion / extraction of the plug blade of a plug. And it can prevent more reliably that the 2nd blade receiving part 2b moves.

When the outer body 10 and the outer cover 11 are coupled, these cutouts 10g and 11 b constitutes the opening 12.

各刃受部は、それぞれ第１の刃受部９０ａと第２の刃受部９１ａとから成り、第１の刃受部９０ａは、長尺の金属板から成る第１の導電板９０において各プラグ差込部１３と対向する位置にそれぞれ一体に設けられ、第２の刃受部９１ａは、長尺の金属板から成る第２の導電板９１において各プラグ差込部１３と対向する位置にそれぞれ一体に設けられている。また、各導電板９０，９１の左端部には、後述するスイッチＳＷの第２の端子部６３に接続される端子部９０ｂ，９１ｂが各々設けられている。 Each blade receiving portion is composed of a first blade receiving portion 90a and a second blade receiving portion 91a, and each of the first blade receiving portions 90a in each of the first conductive plates 90 made of a long metal plate. The second blade receiving portion 91a is integrally provided at a position facing the plug insertion portion 13, and the second blade receiving portion 91a is located at a position facing each plug insertion portion 13 in the second conductive plate 91 made of a long metal plate. Each is provided integrally. In addition, terminal portions 90b and 91b connected to a second terminal portion 63 of a switch SW, which will be described later, are provided at the left end portions of the conductive plates 90 and 91, respectively.

各刃受部は、それぞれ外ボディ１０の左右方向に沿って複数個（図示では２つ）並設された中ボディ４内に保持される。中ボディ４は、例えば上面を開口した略箱体に形成された合成樹脂成形品から成り、その前後方向の略中央には、第１の刃受部９０ａと第２の刃受部９１ａとを機械的且つ電気的に隔てる隔壁４０が突設されている。また、右側に配設される中ボディ４の右側壁には、第１の導電板９０及び第２の導電板９１の右端部に設けられる第１の刃受部９０ａ及び第２の刃受部９１ａを露出させるための露出部４２が貫設されている。 Each blade receiving portion is held in a plurality of (two in the drawing) side-by-side middle bodies 4 along the left-right direction of the outer body 10. The middle body 4 is made of, for example, a synthetic resin molded product formed in a substantially box shape having an upper surface opened, and a first blade receiving portion 90a and a second blade receiving portion 91a are provided at a substantially center in the front-rear direction. A partition wall 40 is provided so as to be separated mechanically and electrically. Further, on the right side wall of the middle body 4 disposed on the right side, the first blade receiving portion 90a and the second blade receiving portion provided at the right end portions of the first conductive plate 90 and the second conductive plate 91 are provided. An exposed portion 42 is provided to expose 91a.

スイッチＳＷは、ハウジング６の左側面から突設される一対の第１の端子部６２と、ハウジング６の右側面から突設される一対の第２の端子部６３とを備える。第１の端子部６２は、それぞれ電線コード８の芯線８ａがかしめ固定されることで外部電源と電気的に接続されるとともに、ハウジング６内部で各第２の端子部６３と電気的に接続されている。ここで、本実施形態のスイッチ機構は、ハンドル５の押操作に応じて一方の第１の端子部６２から一方の第２の端子部６３への通電をオン／オフするものであり、その構成及び動作は実施形態１と同様である。而して、ハンドル５の押操作に応じて外部電源から第２の端子部６３に接続された第１の導電板９０又は第２の導電板９１の何れか一方への通電がオン／オフされるので、１つのスイッチＳＷで全ての刃受部への通電を一括して制御することができる。 The switch SW includes a pair of first terminal portions 62 protruding from the left side surface of the housing 6 and a pair of second terminal portions 63 protruding from the right side surface of the housing 6. The first terminal portion 62 is electrically connected to an external power source by caulking and fixing the core wire 8 a of the electric wire cord 8, and is electrically connected to each second terminal portion 63 inside the housing 6. ing. Here, the switch mechanism of the present embodiment turns on / off the energization from one first terminal portion 62 to one second terminal portion 63 in accordance with the pushing operation of the handle 5, and its configuration The operation is the same as that of the first embodiment. Thus, energization of either the first conductive plate 90 or the second conductive plate 91 connected to the second terminal portion 63 from the external power source is turned on / off according to the pushing operation of the handle 5. Therefore, it is possible to collectively control energization to all the blade receiving portions with one switch SW.

上述のように、各刃受部を個別に保持する中ボディ４を複数個並設したので、全ての刃受部を１個の中ボディ４で保持する場合と比較して、中ボディ４の長手方向の寸法を小さくすることができる。したがって、中ボディ４の上下方向における反りが低減されるので、外カバー１１及び外ボディ１０が中ボディ４の反りによって押されることがなく、外カバー１１と外ボディ１０との間に隙間が生じるのを防ぐことができ、筐体１内部に水が浸入するのを防ぐことができる。尚、プラグ差込部１３及び刃受部の個数を増やしても同様の効果を奏することができるのは言うまでもない。 As described above, since the plurality of middle bodies 4 that individually hold the respective blade receiving portions are arranged side by side, compared to the case where all the blade receiving portions are held by one middle body 4, The longitudinal dimension can be reduced. Accordingly, since the warp in the vertical direction of the middle body 4 is reduced, the outer cover 11 and the outer body 10 are not pushed by the warp of the middle body 4, and a gap is generated between the outer cover 11 and the outer body 10. Can be prevented, and water can be prevented from entering the housing 1. Needless to say, the same effect can be obtained by increasing the number of plug insertion portions 13 and blade receiving portions.
