Description

本願発明は、線状コンセントに対する差し込みプラグの接続構造、並びに、同接続構造に適する差し込みプラグに関するものである。   The present invention relates to a connection structure of an insertion plug to a linear outlet, and an insertion plug suitable for the connection structure.

従来より、特許文献１や２に示すように、電源用の差し込みプラグには、一対の差し込み刃を先端面から突出させたプラグ本体に、凹部や凸部を形成し、この先端面に形成された凹部や凸部によって、差し込み刃間の沿面距離を長くすることにより、差し込み刃間のトラッキングを防止することが提案されている。差し込みプラグのプラグ本体に凹部を形成する場合には、プラグ本体の先端面がコンセントの先端面に当接するまで確実に差し込むことができる。ところが、特許文献２の図５、図６に示されるように、上記の凸部として複数の突条を形成する場合には、突条の先端がコンセントの先端面に当接することとなる。その結果、差し込みプラグの差し込み刃を十分に深く差し込むことができず、コンセントの先端面から差し込み刃が露出してしまうこととなり、埃の堆積などによるトラッキングの原因となるおそれがある。特に、沿面距離を長くするために、突条の高さを高くすればするほど、コンセントの先端面から差し込み刃の露出長さが長くなり、さらに突条の高さを長くすると、差し込み刃がコンセントの刃受けに受容されないという自体が生じるため、突条の突出高さを高くして沿面距離を長くすることには、おのずと限度がある。   Conventionally, as shown in Patent Documents 1 and 2, a plug for power supply has a recess or projection formed in a plug body in which a pair of insertion blades protrudes from the tip surface, and is formed on the tip surface. It has been proposed to prevent tracking between the insertion blades by increasing the creepage distance between the insertion blades by the concave portions or the convex portions. When the recess is formed in the plug body of the plug, it can be surely inserted until the tip surface of the plug body comes into contact with the tip surface of the outlet. However, as shown in FIGS. 5 and 6 of Patent Document 2, when a plurality of protrusions are formed as the above-described convex portions, the tips of the protrusions come into contact with the tip surface of the outlet. As a result, the insertion blade of the insertion plug cannot be inserted sufficiently deep, and the insertion blade is exposed from the front end surface of the outlet, which may cause tracking due to dust accumulation or the like. In particular, the longer the height of the protrusion, the longer the creepage distance, the longer the exposed length of the insertion blade from the tip of the outlet, and the longer the height of the protrusion, the insertion blade There is a limit in increasing the creepage distance by increasing the protrusion height of the ridge, because it is unacceptable by the blade receptacle of the outlet.

他方、コンセントにも多くの種類が存在するところ、特許文献３に示すような、線状コンセント或いはレールコンセントと呼ばれるものがある。この種のコンセントは、壁面の陳列棚やショーケース等の照明用電源をとるために用いられることが多く、一度取り付けられてしまうと、陳列棚の背面に隠れて、視認しにくく多くの埃が溜まった状態で使用されていることが見受けられるため、トラッキング防止の手段が必要と考えられるが、有効な解決策が実施されていないのが現状である。   On the other hand, there are many types of outlets, and there are those called linear outlets or rail outlets as shown in Patent Document 3. This type of outlet is often used to provide power for lighting such as wall display shelves and showcases. Since it can be seen that it is used in the accumulated state, it is considered that a means for preventing tracking is necessary, but at present, no effective solution has been implemented.

FIG. 1 is an explanatory diagram of a use state of a linear outlet and an insertion plug according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of a connection state of the linear outlet and the insertion plug, and FIG. FIG. 4 is a perspective view of the plug, and FIG. 4 is a perspective view showing the internal structure. In the description of the present application, front, rear, left, and right only indicate relative positional relationships, and do not specify an absolute position.

まず、図１、図２を参照して、レールコンセント３０について説明する。このレールコンセント３０は、壁面に設けられた棚やショーケース等における複数の照明器具などの電気器具３８に電源を供給するためなどに用いられるもので、ケーシング３１とこれから延設されたコード３６とを備える。ケーシング３１は通常直線状に長く伸ばされたもので、その先端面３７には左右一対の電源用受容溝３２とその間に配位された接地用受容溝３３とが開口している。電源用受容溝３２の内部には電源用刃受け３４が配位され、接地用受容溝３３の内部には接地用刃受け３５が配位されている。電源用刃受け３４と接地用刃受け３５とはケーシング３１の長手方向にそって互いに平行に長く伸ばされたもので、それぞれがコード３６に接続されて、主電源（図示せず）に接続されることにより、長手方向のどの位置にプラグが差し込まれても電源を供給することができる。   First, the rail outlet 30 will be described with reference to FIGS. 1 and 2. The rail outlet 30 is used for supplying power to an electric appliance 38 such as a plurality of lighting fixtures on a shelf or a showcase provided on a wall surface, and includes a casing 31 and a cord 36 extended therefrom. Is provided. The casing 31 is generally elongated in a straight line, and a pair of left and right power receiving grooves 32 and a grounding receiving groove 33 arranged between the left and right power supply receiving grooves 32 are opened on the front end surface 37 thereof. A power blade receiver 34 is arranged inside the power receiving groove 32, and a ground blade receiver 35 is arranged inside the ground receiving groove 33. The power supply blade receiver 34 and the grounding blade receiver 35 are elongated in parallel with each other along the longitudinal direction of the casing 31, and each is connected to a cord 36 and connected to a main power supply (not shown). As a result, power can be supplied to any position in the longitudinal direction when the plug is inserted.

次に、図２乃至図４を参照して、プラグ１０について説明する。このプラグ１０は、プラグ本体１１と、プラグ本体１１の最先端面１８から突出して設けられた２本の電源用栓刃１２及び１本の接地用栓刃１３と、これらにプラグ１０内で接続された２本の電源コード１５及び１本の接地コード１６とを有する。プラグ本体１１内には、保持部材１４が配位され、この保持部材１４に電源用栓刃１２及び接地用栓刃１３が支持されていると共に電源コード１５及び接地コード１６に接続されて被覆部１７内にインサート成形されている。保持部材１４及び被覆部１７は非導電性の合成樹脂から形成されている。なお、保持部材１４を、被覆部１７よりも硬質のもので形成することによって、電源用栓刃１２及び接地用栓刃１３の保持強度と、コードの柔軟性とを両立させることができる。   Next, the plug 10 will be described with reference to FIGS. The plug 10 is connected to the plug body 11, two power plug blades 12 and one grounding plug blade 13 provided so as to protrude from the most distal surface 18 of the plug body 11, and to the plug 10. Two power cords 15 and one ground cord 16 are provided. A holding member 14 is arranged in the plug body 11, and the power plug blade 12 and the grounding plug blade 13 are supported on the holding member 14 and are connected to the power cord 15 and the ground cord 16 to be covered. 17 is insert-molded. The holding member 14 and the covering portion 17 are made of non-conductive synthetic resin. By forming the holding member 14 to be harder than the covering portion 17, it is possible to achieve both the holding strength of the power plug blade 12 and the grounding plug blade 13 and the flexibility of the cord.

接地用栓刃１３は左右方向において左の電源用栓刃１２と右の電源用栓刃１２との間の中央に位置するものであり、前後方向において電源用栓刃１２の後方に位置するが、前方に位置するものであってもよい。
このプラグ１０には、プラグ本体１１の最先端面１８より突出した絶縁板２１を備える。この絶縁板２１も保持部材１４及び被覆部１７と同様、非導電性の合成樹脂から形成されているが、他の非導電性の素材によって形成してもよい。 The grounding blade 13 is located in the center between the left power blade 12 and the right power blade 12 in the left-right direction, and is located behind the power blade 12 in the front-rear direction. It may be located forward.
The plug 10 includes an insulating plate 21 that protrudes from the most distal surface 18 of the plug body 11. The insulating plate 21 is also made of non-conductive synthetic resin, like the holding member 14 and the covering portion 17, but may be formed of other non-conductive materials.

この絶縁板２１は、電源用栓刃１２及び接地用栓刃１３と平行に形成され、接地用栓刃１３と同様、左右方向において左の電源用栓刃１２と右の電源用栓刃１２との間の中央に位置するものであり、接地用栓刃１３の一直線上に配位されている。前後方向においては、絶縁板２１は左右一対の電源用栓刃１２と上記電源用栓刃間を結ぶ線分上に位置するもので、この例では接地用栓刃１３の前方に位置する。接地用栓刃１３の前後方向幅は、電源用栓刃１２の前後方向幅と等しいかこれよりも長いものとしておき、一対の電源用栓刃１２間を結ぶ直線上には絶縁板２１が常に位置するようにしておくことが望ましい。   The insulating plate 21 is formed in parallel with the power plug blade 12 and the grounding plug blade 13, and similarly to the grounding plug blade 13, the left power plug blade 12 and the right power plug blade 12 in the left-right direction, Are arranged on a straight line of the grounding plug blade 13. In the front-rear direction, the insulating plate 21 is positioned on a line segment connecting the pair of left and right power plug blades 12 and the power plug blade, and in this example is positioned in front of the grounding plug blade 13. The width in the front-rear direction of the grounding blade 13 is set to be equal to or longer than the width in the front-rear direction of the power plug blade 12, and the insulating plate 21 is always on a straight line connecting the pair of power plug blades 12. It is desirable to be positioned.

絶縁板２１の長さ（基端と先端間の距離）は、接地用栓刃１３と略等しいものとしておけばよいが、これよりも短くしてもよい。絶縁板２１の長さによって、左右の電源用栓刃１２間の沿面距離が決定されるため、絶縁板２１を長くしておく方が有利であるが、長すぎると、レールコンセント３０にプラグ１０を差し込んだ際、絶縁板２１が接地用受容溝３３の底にぶつかって栓刃が刃受けに完全に受容されない場合があるため、最長でも接地用栓刃１３と略等しい長さとしておく。他方、絶縁板２１を短くしておくことも可能であり、絶縁板２１を僅かな長さでも設けることによって、絶縁板２１がない場合に比してトラッキング防止性能は向上する。従って、絶縁板２１の長さは、プラグ１０をレールコンセント３０に差し込んだ際、接地用刃受け３５に達するものでなくてもよく、少なくとも接地用受容溝３３内に挿入されるものであればよい。   The length of the insulating plate 21 (the distance between the base end and the tip end) may be substantially equal to that of the grounding plug blade 13, but may be shorter than this. Since the creeping distance between the left and right power plug blades 12 is determined by the length of the insulating plate 21, it is advantageous to make the insulating plate 21 longer, but if it is too long, the plug 10 is connected to the rail outlet 30. Since the insulating plate 21 may hit the bottom of the ground receiving groove 33 when the plug is inserted, the plug blade may not be completely received by the blade receiver. On the other hand, the insulating plate 21 can be shortened. By providing the insulating plate 21 with a small length, the tracking prevention performance is improved as compared with the case where the insulating plate 21 is not provided. Accordingly, the length of the insulating plate 21 does not have to reach the grounding blade receiver 35 when the plug 10 is inserted into the rail outlet 30, and at least as long as it is inserted into the grounding receiving groove 33. Good.

絶縁板２１の左右方向の厚みは、接地用栓刃１３と略同じか、これより薄いものが望ましい。接地用栓刃１３よりも薄くしておくほうが、接地用刃受け３５に円滑に差し込むことができる。ただし、絶縁板２１を短くして接地用刃受け３５に届かない長さとする場合には、接地用受容溝３３の幅以下の厚みにしておけばよい。また、絶縁板２１を長くした場合には、根本では接地用受容溝３３の幅以下の厚みとしておき、先端の接地用刃受け３５に挿入される部分のみを薄くして接地用刃受け３５に挿入されやすいようにしておけばよい。   The thickness of the insulating plate 21 in the left-right direction is preferably substantially the same as or thinner than the grounding plug blade 13. If the thickness is smaller than that of the grounding plug blade 13, the grounding blade receiver 35 can be smoothly inserted. However, when the insulating plate 21 is shortened to a length that does not reach the grounding blade receiver 35, the thickness may be equal to or smaller than the width of the grounding receiving groove 33. When the insulating plate 21 is lengthened, the thickness is set to be equal to or less than the width of the grounding receiving groove 33 at the base, and only the portion inserted into the grounding blade receiver 35 at the tip is thinned to form the grounding blade receiver 35. It should be easy to be inserted.

このプラグ１０は、この例では前記の照明器具３８のコード先端に設けられ、レールコンセント３０に差し込まれる。この挿入によって、図２に示すように、電源用栓刃１２は電源用受容溝３２内の電源用刃受け３４に受容され、接地用栓刃１３は接地用受容溝３３内の接地用刃受け３５に受容される。このとき、絶縁板２１は接地用受容溝３３内に挿入され、絶縁板２１が長い場合には接地用刃受け３５に受容される。このように、絶縁板２１は接地用栓刃１３と共に、接地用受容溝３３内に挿入されるため、プラグ１０の差し込み時に絶縁板２１が邪魔になることはなく、プラグ１０の最先端面１８とレールコンセント３０の先端面３７とが当接するまで、確実に差し込むことができ、安全な電気的接続を維持しつつ、絶縁板２１によるトラッキング防止効果を発揮させることができる。   In this example, the plug 10 is provided at the distal end of the cord of the lighting fixture 38 and is inserted into the rail outlet 30. By this insertion, as shown in FIG. 2, the power plug blade 12 is received by the power supply blade receiver 34 in the power supply receiving groove 32, and the grounding plug blade 13 is received by the grounding blade receiver 33 in the ground receiving groove 33. 35. At this time, the insulating plate 21 is inserted into the grounding receiving groove 33, and when the insulating plate 21 is long, it is received by the grounding blade receiver 35. In this way, since the insulating plate 21 is inserted into the grounding receiving groove 33 together with the grounding plug blade 13, the insulating plate 21 does not get in the way when the plug 10 is inserted, and the most advanced surface 18 of the plug 10. Until the end surface 37 of the rail socket 30 comes into contact with the rail outlet 30, the tracking effect of the insulating plate 21 can be exhibited while maintaining a safe electrical connection.

この絶縁板２１は、プラグ本体１１の被覆部１７と一体に形成することもでき、図４に示すように保持部材１４と一体に形成することもできるが、被覆部１７及び保持部材１４とは別体に形成してもよい。   The insulating plate 21 can be formed integrally with the covering portion 17 of the plug body 11 or can be formed integrally with the holding member 14 as shown in FIG. It may be formed separately.

例えば、図５に示すように、絶縁板２１をプラグ本体１１と別体に形成し、プラグ本体１１に上下方向に貫通した取付部２２を設け、この取付部２２に絶縁板２１を差し込むようにしてもよい。その際、取付部２２と絶縁板２１とは接着してもよいが、樹脂の適当な弾性抵抗をもって強制嵌合させることにより、絶縁板２１をプラグ本体１１に対して出没可能又は着脱可能にしておくこともできる。このように、出没可能又は着脱可能にすることで、接地用受容溝３３のないレールコンセント３０に対しても、絶縁板２１を凹ませるか取り除くことで、プラグ１０をレールコンセント３０に差し込むことができる。   For example, as shown in FIG. 5, the insulating plate 21 is formed separately from the plug body 11, a mounting portion 22 penetrating in the vertical direction is provided in the plug body 11, and the insulating plate 21 is inserted into the mounting portion 22. May be. At this time, the mounting portion 22 and the insulating plate 21 may be bonded together, but the insulating plate 21 can be made to appear in and out of the plug body 11 by being forcedly fitted with an appropriate elastic resistance of the resin. It can also be left. In this way, by making the protrusion / removal or detachable, the plug 10 can be inserted into the rail outlet 30 by denting or removing the insulating plate 21 from the rail outlet 30 without the grounding receiving groove 33. it can.

また図６に示すように、前後方向（図６では紙面の手前奥方向）に溝状の取付部２２を設け、絶縁板２１の基端２３を差し込んで着脱可能にしてもよい。その際、図に示すように、基端２３は絶縁板２１の露出部分よりも大きくしておき、抜け止めとしておくことも望ましい。また、絶縁板２１の基部に厚みを薄くした弱め部２４を設けておいて、この弱め部２４から絶縁板２１の先端側を折り取り可能にしておいてもよい。   Further, as shown in FIG. 6, a groove-like attachment portion 22 may be provided in the front-rear direction (in FIG. 6, the front-rear direction of the paper surface), and the base end 23 of the insulating plate 21 may be inserted to be removable. At that time, as shown in the figure, it is also desirable that the base end 23 is made larger than the exposed portion of the insulating plate 21 to prevent it from coming off. Further, a weakened portion 24 having a reduced thickness may be provided at the base of the insulating plate 21, and the distal end side of the insulating plate 21 may be foldable from the weakened portion 24.
