以下に図面を参照しつつ、本発明の実施形態を説明する。
図２において１０は自動投入装置であり、取付板１１の上に、ブレーカ１２と自動投入装置本体１３とを取付けたものである。自動投入装置本体１３は操作レバー１４を備え、ブレーカ１２が雷電流等によってトリップした際に、ブレーカ１２のハンドル１５をトリップ位置からオン位置に動かしてブレーカ１２を再投入する機能を備えている。自動投入装置１０の全体は、縦長形状である。 Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 2, reference numeral 10 denotes an automatic charging device, in which a breaker 12 and an automatic charging device main body 13 are mounted on a mounting plate 11. The automatic closing device main body 13 includes an operation lever 14 and has a function of moving the handle 15 of the breaker 12 from the trip position to the on position and re-inserting the breaker 12 when the breaker 12 trips due to lightning current or the like. The entire automatic loading apparatus 10 has a vertically long shape.

図２に示すように、取付板１１の上下端部には固定部１６が形成されている。固定部１６は図７に示すように、周囲よりも板厚を薄くした薄板部１６ａと、端部が貫通した貫通部１６ｂとを備えている。この貫通部１６ｂにネジを通し、薄板部１６ａでねじを支えることによって、取付板１１を基板５０（図１１参照）に固定することができる。ただし本実施形態では取付板１１を直接ネジ止めするのではなく、後述するように絶縁保護部材に支持させている。取付板１１の側面には出線孔部１７が形成されており、警報リード線１８が出線されている。この警報リード線１８は、異常発生時に外部の警報ブザーや警報ランプ等を作動させるためのものである。   As shown in FIG. 2, fixing portions 16 are formed at the upper and lower ends of the mounting plate 11. As shown in FIG. 7, the fixing portion 16 includes a thin plate portion 16 a having a thickness that is thinner than the surroundings, and a through portion 16 b through which an end portion passes. The mounting plate 11 can be fixed to the substrate 50 (see FIG. 11) by passing a screw through the through portion 16b and supporting the screw with the thin plate portion 16a. However, in this embodiment, the mounting plate 11 is not directly screwed, but is supported by an insulating protection member as will be described later. An output hole 17 is formed on the side surface of the mounting plate 11 and an alarm lead wire 18 is output. This alarm lead wire 18 is for operating an external alarm buzzer, an alarm lamp, etc. when an abnormality occurs.

本発明の絶縁保護部材は、上記した自動投入装置１０と、自動投入装置１０が取付けられる基板５０との間に挟持され、自動投入装置１０の充電部とアースとの間の絶縁距離を長くし、耐絶縁性能を向上させるものである。本発明の絶縁保護部材は２分割された分割部材２１，２２からなり、各分割部材２１，２２は図２、図３に示されるように自動投入装置１０の周囲を囲む凹形状をしている。具体的には、周囲に自動投入装置１０の外周に沿って立ち上がる絶縁壁部１９が形成され、中央部を自動投入装置１０が収納される凹部２０としたものである。このような構造とすることにより、設置面積や自動投入装置１０の設置高さを大きく変えることなく自動投入装置１０とアース間の絶縁距離を長くし、耐絶縁性能を向上させることができる。   The insulation protection member of the present invention is sandwiched between the automatic loading device 10 and the substrate 50 to which the automatic loading device 10 is attached, and increases the insulation distance between the charging portion of the automatic loading device 10 and the ground. It improves the insulation performance. The insulating protection member of the present invention is composed of two divided members 21 and 22, and each divided member 21 and 22 has a concave shape surrounding the periphery of the automatic loading device 10 as shown in FIGS. 2 and 3. . Specifically, an insulating wall portion 19 that rises along the outer periphery of the automatic charging device 10 is formed in the periphery, and the central portion is a recess 20 in which the automatic charging device 10 is accommodated. By adopting such a structure, it is possible to increase the insulation distance between the automatic loading device 10 and the ground without greatly changing the installation area and the installation height of the automatic loading device 10 and to improve the insulation resistance.

図２、図３に示すように、この実施形態では絶縁保護部材は上下に分割部材２１，２２で分割され、側面の絶縁壁部１９に一体形成された結合部２３，２４によって相互に結合されている。分割部材２１と分割部材２２とは同一形状であり、同一の金型で成形可能である。また図２に示すように、分割部材２１と分割部材２２とを自動投入装置１０の背後で組合せ、結合部２３，２４で結合することによって、工具なしで、また別部材を必要とせずに組み立て可能である。   As shown in FIGS. 2 and 3, in this embodiment, the insulating protection member is divided into upper and lower divided members 21 and 22, and is coupled to each other by coupling portions 23 and 24 integrally formed on the side insulating wall portion 19. ing. The divided member 21 and the divided member 22 have the same shape and can be molded with the same mold. Further, as shown in FIG. 2, the divided member 21 and the divided member 22 are combined behind the automatic feeding device 10 and connected by the connecting portions 23 and 24, thereby assembling without a tool or requiring another member. Is possible.

結合部２３、２４の構造の詳細を図４、図５に示した。結合部２３は縁壁部１９から外側に膨らんだ段差部２５を備え、その上側端部に平板状の凸状ガイド部２６が形成されている。一方、結合部２４にはこの凸状ガイド部２６にスライド挿入される凹状ガイド部２７が形成されている。また結合部２３の基部には内向きの爪部２８が形成され、結合部２４の先端には外向きの爪部２９が形成されている。このため図５に示すように凹状ガイド部２７を凸状ガイド部２６に嵌めてスライドさせながら押し込めば、爪部２８，２９が相互に噛み合ってスライド方向に外れなくなる。さらに、凹状ガイド部２７を凸状ガイド部２６に嵌める構造とすることにより、分割部材２１と分割部材２２が互いに左右方向に移動することを防止する。例えば充電部からの熱等により絶縁保護部材が変形することもあるが、上記の構造により、変形による爪部２８，２９の相互の噛み合わせが外れることを防止する。   Details of the structure of the coupling portions 23 and 24 are shown in FIGS. The coupling portion 23 includes a step portion 25 that swells outward from the edge wall portion 19, and a flat plate-like convex guide portion 26 is formed on the upper end portion thereof. On the other hand, the coupling portion 24 is formed with a concave guide portion 27 slidably inserted into the convex guide portion 26. An inward claw portion 28 is formed at the base of the coupling portion 23, and an outward claw portion 29 is formed at the tip of the coupling portion 24. Therefore, as shown in FIG. 5, when the concave guide portion 27 is fitted into the convex guide portion 26 and slid while being pushed in, the claw portions 28 and 29 are engaged with each other and do not come off in the sliding direction. Furthermore, the structure in which the concave guide portion 27 is fitted to the convex guide portion 26 prevents the divided member 21 and the divided member 22 from moving in the left-right direction. For example, the insulation protection member may be deformed by heat from the charging unit, but the above structure prevents the claws 28 and 29 from being disengaged from each other due to the deformation.

爪部２８，２９は絶縁壁部１９の端面付近に形成されており、凸状ガイド部２６も段差部２５の一部に形成されているだけであるから、図５のように結合した状態においても段差部２５の内側に引出口３０が形成され、この引出口３０から図６に示すように警報リード線１８を外部に引き出すことができる。また、引出口３０の位置は自動投入装置１０の警報リード線１８の出線孔部１７に対して、結合方向に異なる位置に設けている。これによって図６に示したように取付板１１の側面の出線孔部１７と引出口３０との間に絶縁距離を確保している。   Since the claw portions 28 and 29 are formed in the vicinity of the end face of the insulating wall portion 19 and the convex guide portion 26 is also formed only at a part of the step portion 25, in the coupled state as shown in FIG. Further, an outlet 30 is formed inside the stepped portion 25, and the alarm lead 18 can be pulled out from the outlet 30 as shown in FIG. Moreover, the position of the outlet 30 is provided at a position different in the coupling direction with respect to the outlet hole 17 of the alarm lead wire 18 of the automatic loading device 10. As a result, as shown in FIG. 6, an insulation distance is secured between the outlet hole 17 on the side surface of the mounting plate 11 and the outlet 30.

なお、図３に示したように分割部材２１と分割部材２２とは合せ部３１が相互に密着するようになっているが、中央部には空間３２が形成されている。この空間３２は成形誤差を吸収するとともに結合時の摩擦を防ぎ、スムーズに結合できるようにするためのものである。合せ部３１の位置は自動投入装置１０の警報リード線１８の出線孔部１７に対して、結合方向に異なる位置に設けている。これによって図６に示したように取付板１１の側面の出線孔部１７と合せ部３１との間に絶縁距離を確保している。   As shown in FIG. 3, the divided member 21 and the divided member 22 are configured such that the mating portion 31 is in close contact with each other, but a space 32 is formed in the central portion. This space 32 is for absorbing molding errors and preventing friction at the time of coupling so that the coupling can be performed smoothly. The position of the mating portion 31 is provided at a position different in the coupling direction with respect to the outgoing hole portion 17 of the alarm lead wire 18 of the automatic loading device 10. As a result, as shown in FIG. 6, an insulation distance is secured between the outgoing hole 17 on the side surface of the mounting plate 11 and the mating portion 31.

図２、図３に示すように、分割部材２１と分割部材２２の上下の絶縁壁部１９には、自動投入装置１０との係止部３３が一体に形成されている。その詳細は図７、図８に示す通りであり、係止部３３は前記した取付板１１の固定部１６の両側面と平行に突出形成されている。このため図８に示すように、取付板１１の固定部１６に係止部３３が嵌まり込み、自動投入装置１０の取付板１１と上側の分割部材２１とが係止される。これによって自動投入装置１０は上下方向に移動しないように固定される。また係止部３３には取付板１１の固定部１６に形成された貫通部１６ｂの奥部に係合する突起３４と、薄板部１６ａの両側壁に当接する２枚の立上壁３５が形成され、突起３４と立上壁３５は係止部３３を補強すると同時に、自動投入装置１０を左右方向に移動することを防ぐ役割がある。図８に示すように突起３４も同時に取付板１１に係止される。下側の分割部材２２についても同様である。なお、係止部３３は取付板１１のうち固定部１６以外の箇所に係止してもよい。   As shown in FIGS. 2 and 3, the upper and lower insulating wall portions 19 of the split member 21 and the split member 22 are integrally formed with a locking portion 33 for the automatic feeding device 10. The details are as shown in FIGS. 7 and 8, and the locking portion 33 is formed so as to protrude in parallel with both side surfaces of the fixing portion 16 of the mounting plate 11. For this reason, as shown in FIG. 8, the latching | locking part 33 fits in the fixing | fixed part 16 of the mounting plate 11, and the mounting plate 11 and the upper division member 21 of the automatic loading apparatus 10 are latched. As a result, the automatic charging device 10 is fixed so as not to move in the vertical direction. Further, the locking portion 33 is formed with a protrusion 34 that engages with the inner portion of the through portion 16b formed in the fixing portion 16 of the mounting plate 11, and two rising walls 35 that abut against both side walls of the thin plate portion 16a. The protrusion 34 and the rising wall 35 reinforce the locking portion 33 and at the same time have a role of preventing the automatic loading device 10 from moving in the left-right direction. As shown in FIG. 8, the projection 34 is also locked to the mounting plate 11 at the same time. The same applies to the lower divided member 22. Note that the locking portion 33 may be locked to a portion other than the fixing portion 16 in the mounting plate 11.

このような構造とすれば、上側の分割部材２１と下側の分割部材２２とをスライドさせるだけで結合部２３，２４が相互に結合されると同時に、係止部３３が固定部１６にスライドして係止され、工具を用いることなく、またネジ等の取付部材を必要とせずに自動投入装置１０への取付が可能である。このため、分割部材どうしを結合する作業で、自動投入装置１０の絶縁保護部材への取り付けも同時に行うことができ、作業性の向上を図ることができる。また、自動投入装置１０を絶縁保護部材の底面３７にネジ止めする必要が無いので、底面３７の強度を高める必要が無くなり、底面３７の厚みを抑え、絶縁保護部材を低く形成することができる。   With such a structure, the coupling portions 23 and 24 are coupled to each other only by sliding the upper division member 21 and the lower division member 22, and at the same time, the locking portion 33 slides to the fixing portion 16. Thus, it is possible to mount the automatic feeding device 10 without using a tool and without requiring a mounting member such as a screw. For this reason, in the operation | work which couple | bonds a division member, the automatic insertion apparatus 10 can be attached to the insulation protection member simultaneously, and workability | operativity can be aimed at. Further, since it is not necessary to screw the automatic loading device 10 to the bottom surface 37 of the insulation protection member, it is not necessary to increase the strength of the bottom surface 37, the thickness of the bottom surface 37 can be suppressed, and the insulation protection member can be formed low.

なお、絶縁壁部１９の係止部３３の外側位置には、前記の基板５０に絶縁保護部材を固定するためのＵ字状の固定部３６が設けられており、基板５０に全体をネジ等によって固定できるようになっている。この固定部３６は、自動投入装置１０の上下位置に形成されている。   A U-shaped fixing portion 36 for fixing the insulating protection member to the substrate 50 is provided at a position outside the locking portion 33 of the insulating wall portion 19. It can be fixed by. The fixing portion 36 is formed at the vertical position of the automatic loading device 10.

本発明の絶縁保護部材を自動投入装置１０に組み付けた状態を図９〜図１１に示す。自動投入装置１０の外周に絶縁壁部１９が立ち上がっており、この絶縁壁部１９によって自動投入装置１０とアースとなる基板５０との間の絶縁距離が延長されるため、盤を大型化することなく自動投入装置１０の耐絶縁性能を向上させることができる。   FIGS. 9 to 11 show the state in which the insulating protective member of the present invention is assembled to the automatic loading device 10. An insulating wall 19 stands on the outer periphery of the automatic loading device 10, and the insulating wall 19 extends the insulation distance between the automatic loading device 10 and the substrate 50 serving as a ground, so that the size of the panel is increased. Insulation resistance of the automatic charging device 10 can be improved.

図９に示されるように、上下の絶縁壁部１９はブレーカ１２の端子座よりも低く形成し、左右の絶縁壁部１９はブレーカ１２の端子座よりも高く形成されている。上下の絶縁壁部１９はブレーカ１２の端子座への配線の都合上、高くすることは好ましくない。このため本実施形態では上下の絶縁壁部１９の高さはブレーカ１２の端子座よりも低くし、これと直交する絶縁隔壁１９は端子座よりも高くした。   As shown in FIG. 9, the upper and lower insulating wall portions 19 are formed lower than the terminal seat of the breaker 12, and the left and right insulating wall portions 19 are formed higher than the terminal seat of the breaker 12. It is not preferable to make the upper and lower insulating wall portions 19 high for the convenience of wiring to the terminal seat of the breaker 12. Therefore, in this embodiment, the height of the upper and lower insulating wall portions 19 is set lower than the terminal seat of the breaker 12, and the insulating partition wall 19 orthogonal thereto is set higher than the terminal seat.

このように上下の絶縁壁部１９の高さを低くすると絶縁距離が小さくなるが、前記したように固定部３６を上下の絶縁隔壁１９に形成し、絶縁保護部材の上下方向の距離を伸ばすことによって、絶縁距離を確保している。よって配線の邪魔になることはなく、また幅を広げることなく、耐電圧性能を高めることができる。   As described above, when the height of the upper and lower insulating wall portions 19 is lowered, the insulation distance is reduced. As described above, the fixing portion 36 is formed on the upper and lower insulating partition walls 19 to increase the vertical distance of the insulating protection member. Therefore, the insulation distance is secured. Therefore, the withstand voltage performance can be improved without interfering with the wiring and without increasing the width.
