本発明は、屋外に設置される太陽光発電装置等における筐体を形成するパネルのコネクタ取付孔に水密性を維持して取付ける複数のパネルマウントコネクタ（プラグ及び/又はジャック）間の誤挿入防止構造に関するものである。
The present invention prevents erroneous insertion between a plurality of panel mount connectors (plugs and / or jacks) which are attached to a connector mounting hole of a panel forming a casing in a photovoltaic power generation apparatus or the like installed outdoors while maintaining watertightness. Concerning structure.
従来、パネルマウントコネクタにおけるプラグやジャックのパネル取付方法は、図１０Ａ、図１０Ｂに示すように、丸型のパネル取付用コネクタの同軸コンタクト２１、丸型コンタクト２２におけるパネル固定方法において、パネルの取付孔に前記コンタクトを装着した後に当該コンタクトが抜け出ないように、環状の凹溝２１ａ，２２ａに嵌合させた収縮可能な係止片２３を用いてワンタッチ式のロック方法となっているものが知られている。前記係止片２３は、図１０Ｃに示すように、環状で一部が切欠かれた形状であり、挿入方向の先端側外径が次第に細くされたテーパ状部２３ａを有している。
Conventionally, as shown in FIGS. 10A and 10B, a panel mounting method for plugs and jacks in a panel mount connector is the same as the panel fixing method in the coaxial contact 21 and the round contact 22 of the round panel mounting connector. A one-touch type locking method using a retractable locking piece 23 fitted in the annular concave grooves 21a, 22a is known so that the contact does not come out after the contact is mounted in the hole. It has been. As shown in FIG. 10C, the locking piece 23 has an annular shape with a part cut away, and has a tapered portion 23 a in which the outer diameter on the distal end side in the insertion direction is gradually narrowed.
従来のパネルマウントコネクタ（プラグ又はジャック）は、平板状のパネルに穿設された丸形の取付孔に挿入して、前記係止片により抜け防止されるものであって、脱着防止用の係止片を設けているが、複数のコネクタプラグとコネクタジャックとが、通常前記パネルに取付けられることが多い。しかしながら、それら複数のパネルマウントコネクタ間の誤挿入防止対策がなされていないことから、前記コネクタの取付け工程において、パネルマウントコネクタにおけるプラグ又はジャック、その他異なるコネクタ等の異種のコネクタにおける、それぞれの取付け位置を誤るおそれがある。本発明に係るパネルマウントコネクタの誤挿入防止構造は、このような課題を解決するために提案されたものである。
A conventional panel mount connector (plug or jack) is inserted into a round mounting hole formed in a flat panel and is prevented from being detached by the locking piece. Although a stop piece is provided, a plurality of connector plugs and connector jacks are usually attached to the panel in many cases. However, since measures for preventing erroneous insertion between the plurality of panel mount connectors are not taken, in the connector mounting process, plugs or jacks in the panel mount connector, and other mounting positions in different connectors such as different connectors, etc. There is a risk of mistakes. The structure for preventing erroneous insertion of a panel mount connector according to the present invention has been proposed in order to solve such a problem.
本発明に係るパネルマウントコネクタの誤挿入を防止する構造は、平板状のパネルに穿設された複数の取付孔に複数のパネルマウントコネクタをそれぞれ取り付ける際のコネクタ相互間の誤挿入防止構造であって、各パネルマウントコネクタは、それぞれの取付孔に対向する側の外周面に形成された凹溝と、該凹溝に嵌合される弾性係止片を備え、該弾性係止片は抜止め用の環状本体部とその環状本体部の一部に形成された切欠き部と該切欠き部の端部に形成した突起部とを有し、該各パネルマウントコネクタの取付孔側の外周面先端側には、該係止片の突起部を抜け止めするように上方に突出形成した段部を有するとともに、該取付孔には該段部を通過させるための通過溝を形成し、それぞれ対応する取付孔に取付可能とし、一方のパネルマウントコネクタの段部と他方のパネルマウントコネクタの段部とは形状および大きさが異なるように形成するとともに、一方のパネルマウントコネクタ用の取付孔における通過溝と他方のパネルマウントコネクタ用の取付孔の通過溝との形状および大きさが異なるように形成して、両コネクタ相互間の誤挿入を防止するよう構成している。
The structure for preventing erroneous insertion of a panel mount connector according to the present invention is a structure for preventing erroneous insertion between connectors when a plurality of panel mount connectors are respectively attached to a plurality of mounting holes formed in a flat panel. Each panel mount connector includes a concave groove formed on the outer peripheral surface on the side facing each mounting hole, and an elastic locking piece fitted into the concave groove, and the elastic locking piece is retained. An annular body part, a notch part formed in a part of the annular body part, and a projection part formed at an end part of the notch part, and an outer peripheral surface on the mounting hole side of each panel mount connector On the tip side, there is a stepped part that protrudes upward so as to prevent the protruding part of the locking piece from coming off, and a passage groove for passing the stepped part is formed in the mounting hole. Can be installed in the mounting hole The step portion of the mount connector and the step portion of the other panel mount connector are formed so as to have different shapes and sizes, and the passage groove in the attachment hole for one panel mount connector and the attachment hole for the other panel mount connector The passage groove has a shape and a size different from each other to prevent erroneous insertion between the two connectors.
前記他方のパネルマウントコネクタの段部には凹状の切欠きスリット若しくは突起が形成されるとともに、対応する取付孔の通過溝には、該切欠きスリット若しくは突起を通過可能とする相補的な突部若しくは溝が形成されるとともに、該突部若しくは溝は、該係止片の突起部が取付孔を通過する際の収縮作用を邪魔しない範囲内に形成されていることが好ましい。
A concave notch slit or protrusion is formed in the step of the other panel mount connector, and a complementary protrusion that allows the notch slit or protrusion to pass through the passage groove of the corresponding mounting hole. Or while a groove | channel is formed, it is preferable that this protrusion or groove | channel is formed in the range which does not disturb the contraction effect | action when the protrusion part of this latching piece passes an attachment hole.
さらに、複数のパネルマウントコネクタが種類の異なるコネクタプラグ同士、又は、コネクタジャック同士である場合には、係止片用の段部と該段部用の通過溝の外に、該段部から周方向に離れた位置にさらなる突起を形成し、対応する取付孔には該突起が通過できる溝を形成することが好ましい。
In addition, when the plurality of panel mount connectors are different types of connector plugs or connector jacks, the peripheral portions are separated from the step portion for the locking piece and the passage groove for the step portion. It is preferable that a further protrusion is formed at a position away from the direction, and a groove through which the protrusion can pass is formed in the corresponding mounting hole.
本発明のパネルマウントコネクタの誤挿入防止構造によれば、一方のパネルマウントコネクタ用の取付孔における通過溝と他方のパネルマウントコネクタ用の取付孔の通過溝との形状および大きさが異なるように形成したことにより、パネルマウントコネクタにおけるコネクタプラグとコネクタジャックとを取り違えて、パネルに取付けてしまうような作業ミスを事前に防ぐことができるとともに、抜止め用の係止片の取付孔挿通時の収縮を邪魔しない範囲において前記誤挿入防止構造が設けられているので、抜け止め防止を確実に発揮しつつ誤挿入を防止できるものである。
According to the structure for preventing erroneous insertion of the panel mount connector of the present invention, the shape and size of the passage groove in the attachment hole for one panel mount connector and the passage groove of the attachment hole for the other panel mount connector are different. By forming it, the connector plug and connector jack in the panel mount connector can be mistaken to prevent work mistakes such as attaching to the panel in advance, and at the time of insertion of the retaining piece of the retaining piece for retaining Since the erroneous insertion preventing structure is provided in a range that does not disturb the contraction, the erroneous insertion can be prevented while reliably preventing the removal.
また、複数のパネルマウントコネクタが種類の異なるコネクタプラグ同士、又は、コネクタジャック同士である場合にも、係止片用の段部と該段部用の通過溝の外に、該段部から周方向に離れた位置にさらなる突起を形成し、対応する取付孔には該突起が通過できる溝を形成することによって、事前に、コネクタプラグ同士、あるいは、コネクタジャック同士における取付けミスを防止できるようになるという優れた効果を奏するものである。
In addition, even when the plurality of panel mount connectors are connector plugs of different types or connector jacks, the peripheral portions are separated from the step portion for the locking piece and the passage groove for the step portion. By forming a further protrusion at a position away from the direction and forming a groove through which the protrusion can pass in the corresponding mounting hole, it is possible to prevent a mounting error between connector plugs or connector jacks in advance. It has an excellent effect of becoming.
本発明に係るパネルマウントコネクタの誤挿入防止構造は、図１Ａ乃至図７Ｄに示すように、パネルマウントコネクタ（プラグ及びジャック）における係止片の突起部を抜け止めするために、それぞれの取付孔に形成された段部を通過させる通過溝をパネルの取付孔に形成するとともに、一方のパネルマウントコネクタ（プラグ又はジャック）に前記係止片の取付孔通過時の収縮作用を邪魔しない範囲において誤挿入防止手段を設けるものである。
As shown in FIGS. 1A to 7D, the structure for preventing erroneous insertion of a panel mount connector according to the present invention is provided with each mounting hole in order to prevent the protrusion of the locking piece in the panel mount connector (plug and jack) from coming off. A passage groove that passes through the step formed in the panel is formed in the mounting hole of the panel, and one panel mount connector (plug or jack) has an error within a range that does not interfere with the contraction action when the locking piece passes through the mounting hole. An insertion preventing means is provided.
本発明の第１実施例に係るパネルマウントコネクタの誤挿入防止構造におけるコネクタプラグ１は、図１Ａおよび図１Ｂに示すように、当該コネクタプラグ１の取付孔側の外周面に形成された凹溝１ａに嵌合されるコネクタ抜止め用の環状本体部２ｄと、その環状本体部２ｄの一部に形成した切欠き部２ｂとからなる弾性係止片２を有する。
As shown in FIGS. 1A and 1B, the connector plug 1 in the erroneous insertion prevention structure for the panel mount connector according to the first embodiment of the present invention is a concave groove formed on the outer peripheral surface of the connector plug 1 on the mounting hole side. It has an elastic locking piece 2 composed of an annular main body portion 2d for retaining a connector fitted to 1a and a notch portion 2b formed in a part of the annular main body portion 2d.
該係止片２は、図２に示すように、環状でその一部に切欠き部２ｂを形成してなる本体部２ｄを有し、挿入方向の先端側外径が次第に細くされたテーパ状部２３ａを有する。該本体部２ｄの切欠き部２ｂを挟んで対向する両端縁部には、前記本体部２ｄの軸線ａ方向の端面両側から前記軸線ａ方向に突出させた突出部２ｃがそれぞれ形成されている。
As shown in FIG. 2, the locking piece 2 has a main body 2d formed in an annular shape with a notch 2b formed in a part thereof, and has a tapered shape in which the outer diameter on the distal end side in the insertion direction is gradually narrowed. Part 23a. Protruding portions 2c that protrude in the axis a direction from both ends of the main body portion 2d in the direction of the axis a are formed at both ends of the main body 2d that face each other across the notch 2b.
前記両突出部２ｃは、切欠き部２ｂを挟んで一対で対向して全部で４カ所にあるが、パネル３側の取付孔３ａとの引掛かりを確保するのが目的なので、最低限、軸線ａの後端側に突出部２ｃがあれば良いので、後端側のみに、切欠き部２ｂを挟んで対向した２カ所の突出部２ｃとしてもよい。更に、前記突出部２ｃが、係止片２の幅ｂを超えて軸線ａ方向に突出しているのは、嵌合相手の凹溝１ａにおいて、係止片２が遊嵌して摺接する範囲内の外周壁面に凸部等の障害物を形成することができないからである。
The projecting portions 2c are in a total of four locations facing each other across the notch portion 2b. However, since the purpose is to secure a catch with the mounting hole 3a on the panel 3 side, at least the axis line Since the protrusion 2c only needs to be provided on the rear end side of a, only the rear end side may have two protrusions 2c opposed to each other with the notch 2b interposed therebetween. Further, the protruding portion 2c protrudes in the direction of the axis a beyond the width b of the locking piece 2 within the range where the locking piece 2 is loosely fitted and slidably contacted in the mating groove 1a. This is because an obstacle such as a convex portion cannot be formed on the outer peripheral wall surface of the plate.
図３および図４に示すように、パネル３は、前記コネクタプラグ１を取り付けるための取付孔３ａと段差部３ｇとを有する。取付孔３ａの内側開口部を縮径してなる凸リング３ｂの上端側にはコネクタプラグ１の段部１ｂが通過するための通過溝３ｃが形成されている。そして、凸リング３ｂは、前記係止片２が取付孔３ａを縮径されて通過して拡張した後に抜止め用のストッパーとして機能する。
As shown in FIGS. 3 and 4, the panel 3 has an attachment hole 3a for attaching the connector plug 1 and a step portion 3g. A passage groove 3c through which the step portion 1b of the connector plug 1 passes is formed on the upper end side of the convex ring 3b formed by reducing the diameter of the inner opening of the mounting hole 3a. The convex ring 3b functions as a stopper for retaining after the locking piece 2 has been reduced in diameter through the mounting hole 3a and expanded.
このように、コネクタプラグ１がパネル３の取付孔３ａに装着されると、図４に示すように、コネクタプラグ１のフランジ部１ｍがパネル３の段差部３ｇに当接するとともに、係止片２によって抜け止めされる。
Thus, when the connector plug 1 is installed in the mounting hole 3a of the panel 3, the flange portion 1m of the connector plug 1 abuts against the step portion 3g of the panel 3 as shown in FIG. Is prevented from falling off.
一方、パネルマウントコネクタの誤挿入防止構造におけるコネクタジャック１ｇは、図６Ａおよび図６Ｂに示すように、取付孔側の構成は上述したコネクタプラグ１とほぼ共通しているが、係止片２を遊嵌させる凹溝１ａの先端側と後端側の２箇所にそれぞれ凹状の切欠きスリット１ｊが形成されている点が異なる。
On the other hand, as shown in FIGS. 6A and 6B, the connector jack 1g in the structure for preventing erroneous insertion of the panel mount connector is substantially the same as the connector plug 1 described above. The difference is that concave notch slits 1j are formed at two positions on the front end side and the rear end side of the concave groove 1a to be loosely fitted.
前記切欠きスリット１ｊが形成される位置は、取付孔に対向する側の第２の段部１ｋにおいて、係止片２が取付孔３ａ通過時に縮径する際、突起部２ａが周方向に移動して、両突起部２ａ間の最も狭くなる範囲を示す範囲ｄ（図７Ａ参照）の内側である。
The notch slit 1j is formed at the position where the protrusion 2a moves in the circumferential direction when the locking piece 2 is reduced in diameter when passing through the mounting hole 3a in the second step 1k on the side facing the mounting hole. And it is inside the range d (refer FIG. 7A) which shows the narrowest range between both the protrusion parts 2a.
上述したように、この範囲ｄの内側に前記スリット１ｊが形成されるので、係止片２の縮径（収縮）作用の邪魔になることがない。こうして、係止片２による抜止め作用を確実にして、そのための第２の通過溝３ｆの範囲内において、誤挿入防止機構を兼用させるように構成したものである。
As described above, since the slit 1j is formed inside the range d, it does not interfere with the diameter reduction (contraction) action of the locking piece 2. In this way, the retaining action by the locking piece 2 is ensured, and the erroneous insertion preventing mechanism is also used within the range of the second passage groove 3f for that purpose.
前記コネクタプラグ１の段部１ｂと前記コネクタジャック１ｇの第２段部１ｋとは、その横幅の大きさが、１ｂ＜１ｋとなっている。それと同様に、前記取付孔３ａの通過溝３ｃと、図７Ａに示す第２の通過溝３ｆとは、溝の間隔の大きさが、３ｃ＜３ｆとなっていて、前記コネクタジャック１ｇを図３に示すコネクタプラグ用の取付孔３ａに挿入することができないように構成されている。
The width of the step 1b of the connector plug 1 and the second step 1k of the connector jack 1g is 1b <1k. Similarly, the size of the gap between the passage groove 3c of the mounting hole 3a and the second passage groove 3f shown in FIG. 7A is 3c <3f. It is comprised so that it cannot insert in the attachment hole 3a for connector plugs shown in FIG.
また、パネル３側の取付孔３ａには、図７Ａに示すように、内側に突出させた突部３ｄを形成している。当該突部３ｄを形成する位置は、前述と同様に、係止片２が取付孔３ａ通過時に縮径する際、突起部２ａが周方向に移動して、両突起部２ａ間の最も狭くなる範囲を示す範囲ｄの内側である。
Further, as shown in FIG. 7A, a protrusion 3d that protrudes inward is formed in the mounting hole 3a on the panel 3 side. The position where the protrusion 3d is formed is the narrowest between the protrusions 2a when the locking piece 2 is reduced in diameter when passing through the mounting hole 3a, as described above, when the protrusion 2a moves in the circumferential direction. It is inside the range d indicating the range.
前記先端側の切欠きスリット１ｊがパネル３の突部３ｄを通過して、後端側の切欠きスリット１ｊが前記突部３ｄに嵌まる。この突部３ｄと、前記切欠きスリット１ｊとが、誤挿入防止手段となるものである。これにより、コネクタプラグ１を、図７Ａに示すコネクタジャック用の取付孔３ａに挿入しても前記突部３ｄに衝突して、挿入できない。
The notch slit 1j on the front end side passes through the protrusion 3d of the panel 3, and the notch slit 1j on the rear end side fits in the protrusion 3d. The protrusion 3d and the notch slit 1j serve as erroneous insertion prevention means. Thereby, even if the connector plug 1 is inserted into the connector jack mounting hole 3a shown in FIG. 7A, it collides with the protrusion 3d and cannot be inserted.
前記コネクタプラグ１とコネクタジャック１ｇとをパネル３にそれぞれ取付けて固定する場合、上述したような誤挿入防止手段が一方のコネクタジャック１ｇとその取付孔側にあることで、複数のパネルマウントコネクタ間の誤挿入を防止できるのである。
When the connector plug 1 and the connector jack 1g are respectively attached and fixed to the panel 3, the above-described erroneous insertion preventing means is provided on one connector jack 1g and its mounting hole side, so that a plurality of panel mount connectors can be connected. It is possible to prevent erroneous insertion.
このほか、例えば、パネル３の取付孔３ａに、種類の異なる複数のコネクタプラグ１同士が取り付けられる場合には、図８に示すように、段部１ｂから周方向に略９０度離れた位置に、突部１ｆを一つ形成する。対応させてパネル３側の取付孔３ａにも、図５Ａに示すように、溝３ｅを形成する。このようにすることで、種類の異なるコネクタプラグ１同士における誤挿入を防止できる。
In addition, for example, when a plurality of different types of connector plugs 1 are attached to the attachment hole 3a of the panel 3, as shown in FIG. 8, the position is approximately 90 degrees away from the stepped portion 1b in the circumferential direction. One protrusion 1f is formed. Correspondingly, a groove 3e is also formed in the mounting hole 3a on the panel 3 side as shown in FIG. 5A. By doing so, it is possible to prevent erroneous insertion between different types of connector plugs 1.
また、種類の異なるコネクタプラグ１が多数ある場合には、突部１ｆを形成する位置を変えて対応し、パネル３側の取付孔３ａにおいても、図５Ｂおよび図５Ｃに示すように、溝３ｅの位置を変えることで多数のパネルマウントコネクタプラグ１の誤挿入を防止することができる。
Further, when there are a large number of different types of connector plugs 1, the positions where the projections 1 f are formed are changed, and the mounting holes 3 a on the panel 3 side also have grooves 3 e as shown in FIGS. 5B and 5C. It is possible to prevent erroneous insertion of a large number of panel mount connector plugs 1 by changing the position.
さらに、コネクタジャック１ｇにおいても、種類の異なる多数のジャック１ｇをパネル３に取り付ける場合には、図７Ｂ～図７Ｄに示すように、パネル３側の取付孔３ａの周方向に離れた位置の各所に溝３ｅを形成するとともに、ジャック１ｇにそれらの溝３ｅそれぞれに対応する位置に突部１ｆをそれぞれ形成する。
Further, in the case of the connector jack 1g, when a large number of different types of jacks 1g are attached to the panel 3, as shown in FIGS. 7B to 7D, various positions at positions separated in the circumferential direction of the mounting holes 3a on the panel 3 side. The groove 3e is formed in the jack 1g, and the protrusion 1f is formed in the jack 1g at a position corresponding to each of the grooves 3e.
この場合、一つの取付孔３ａに複数の溝３ｅを形成し、種類の異なる複数のコネクタプラグ１（又はジャック１ｇ）に、上記複数の溝に対応した複数の突部を形成しても、複数のコネクタプラグ１（又はジャック１ｇ）を誤挿入することなく取り付けられるのは勿論であるが、一つの突部１ｆを有するパネルマウントコネクタプラグ１（又はジャック１ｇ）までが取り付けられてしまう可能性があるので、この弊害を避けるために、各取付孔３ａには、一つだけの、位置が異なる溝３ｅを形成するようにすることが、必要条件となる。
In this case, even if a plurality of grooves 3e are formed in one mounting hole 3a and a plurality of protrusions corresponding to the plurality of grooves are formed in a plurality of different types of connector plugs 1 (or jacks 1g), a plurality of Of course, the connector plug 1 (or jack 1g) may be attached without being erroneously inserted, but the panel mount connector plug 1 (or jack 1g) having one protrusion 1f may be attached. Therefore, in order to avoid this problem, it is necessary to form only one groove 3e having a different position in each mounting hole 3a.
このようにして、パネル３に種類の異なる複数個のコネクタプラグ１（またはジャック１ｇ）同士を取り付ける場合にも、溝の位置が相違するように形成して、種類の異なる複数個のコネクタプラグ（またジャック）同士の場合でも、誤挿入しないように構成する。
In this way, even when a plurality of different types of connector plugs 1 (or jacks 1g) are attached to the panel 3, they are formed so that the positions of the grooves are different so that a plurality of different types of connector plugs ( Moreover, even in the case of jacks), it is configured so as not to be inserted erroneously.
