Description
本発明は、車載用プラグ端子箱の構造に関する。 The present invention relates to a structure of an on-vehicle plug terminal box.
電子機器には、他の電子機器との信号送受を行う信号線を接続するために接続プラグが差し込まれるプラグ端子が設けられている。プラグ端子には接続プラグの突起が差し込まれる端子穴が設けられ、この端子穴に差し込まれた接続プラグの突起は、当該端子穴を介して信号処理基板と電気的に接続され、各種信号の入出力が可能となる。 The electronic device is provided with a plug terminal into which a connection plug is inserted in order to connect a signal line for performing signal transmission / reception with another electronic device. The plug terminal is provided with a terminal hole into which the protrusion of the connection plug is inserted. The protrusion of the connection plug inserted into the terminal hole is electrically connected to the signal processing board through the terminal hole, and various signal inputs are made. Output is possible.
この端子穴は、接続プラグの突起が差し込まれている場合には問題ないが、接続端子の突起が差し込まれていないときには、端子穴が外部に完全に露出することになる。この場合、外部に露出した端子穴の内部に粉塵等が侵入してしまい、電気的接続の不良などを招く恐れがある。 This terminal hole has no problem when the projection of the connection plug is inserted, but when the projection of the connection terminal is not inserted, the terminal hole is completely exposed to the outside. In this case, dust or the like may enter the inside of the terminal hole exposed to the outside, which may cause poor electrical connection.
そこで、端子の接続を行わない場合にこの端子穴を覆う蓋が提案されている。例えば、特許文献１にはテレビ受像機のフロントパネルに設けられたピンジャックを覆う蓋が記載されている。フロントパネルのピンジャックの取付けられる部分は段差加工され、蓋はこの段差部を覆うように構成されている。蓋は平板であって、長手方向の一側縁に厚みを薄くすることによって形成した弾性ヒンジ部を介してフロントパネルに回転自在に取付けられている。そして、蓋がフロントパネルのピンジャックを覆うように閉じられる際には、蓋に設けられたロック爪がフロントパネルに設けられたロック爪係止穴に嵌まり込んで弾性ヒンジ部の変形抵抗による蓋の開方向への反発力に打ち勝って蓋が閉止状態を保つように構成されている。 Therefore, a lid that covers the terminal hole when the terminal is not connected has been proposed. For example, Patent Literature 1 describes a lid that covers a pin jack provided on a front panel of a television receiver. A portion of the front panel to which the pin jack is attached is processed with a step, and the lid is configured to cover the step. The lid is a flat plate, and is rotatably attached to the front panel via an elastic hinge portion formed by reducing the thickness at one side edge in the longitudinal direction. When the lid is closed so as to cover the pin jack of the front panel, the lock claw provided on the lid fits into the lock claw engagement hole provided on the front panel, and the deformation resistance of the elastic hinge portion The lid is configured to keep the closed state by overcoming the repulsive force in the opening direction of the lid.
ところで、近年の車両はＶＴＲ等の電子機器を搭載しており、これらの電子機器と外部の電子機器とを信号線で接続するためのプラグ端子が設けられている。ＶＴＲ等の電子機器はオーディオ信号とビデオ信号の複数の信号線を接続することが必要となることから、複数のプラグ端子が取付けられたプラグ端子箱が車室内のセンターコンソールなどに組み込まれている場合が多い。このようなプラグ端子箱もプラグ端子の穴に異物が入り込まないようにプラグ端子を覆う蓋が取付けられているが、狭い車室内でこの蓋を開けて接続プラグをプラグ端子に挿入する際にはより良好な挿入性、操作性が求められている。また、蓋の開閉操作において、蓋が見えない状態でも蓋の開閉状態が認識できる様に蓋の開閉の際の節度感など、開閉操作感の向上が求められている。 Incidentally, recent vehicles are equipped with electronic devices such as VTRs, and are provided with plug terminals for connecting these electronic devices and external electronic devices with signal lines. Since an electronic device such as a VTR needs to connect a plurality of signal lines of an audio signal and a video signal, a plug terminal box to which a plurality of plug terminals are attached is incorporated in a center console or the like in a vehicle interior. There are many cases. Such a plug terminal box is also provided with a cover that covers the plug terminal so that foreign matter does not enter the hole of the plug terminal, but when opening the cover and inserting the connection plug into the plug terminal in a narrow vehicle compartment There is a demand for better insertability and operability. Further, in the opening / closing operation of the lid, an improvement in opening / closing operation feeling such as a moderation feeling when opening / closing the lid is required so that the opening / closing state of the lid can be recognized even when the lid is not visible.
しかし、特許文献１に記載された従来技術の蓋は、蓋の表面にロック爪が突出した構造となっていることから、蓋を開けてピンジャックに接続端子を差し込む際に、ロック爪が邪魔になって接続端子の挿入性が悪くなってしまうという問題があった。また、特許文献１に記載された従来技術の蓋は、弾性ヒンジによって回転自在に取付けられているので、接続端子を挿入する際に蓋の開角度を大きくしたい場合には蓋を手で保持する必要があるので差込の操作性が悪く、蓋の開閉状態による節度感が無く操作感も劣るという問題があった。更に、ロック爪が設けられているため、蓋を開けた際の意匠性が悪く、蓋の金型の製造コストが高くなってしまうという問題があった。このため、特許文献１に記載された従来技術の蓋を車載用のプラグ端子箱の蓋に適用しても上記のような要請にこたえることは困難であった。 However, since the cover of the prior art described in Patent Document 1 has a structure in which a lock claw protrudes from the surface of the cover, the lock claw is an obstacle when the cover is opened and the connection terminal is inserted into the pin jack. As a result, there is a problem that the insertion property of the connection terminal is deteriorated. Moreover, since the lid of the prior art described in Patent Document 1 is rotatably mounted by an elastic hinge, when the connection terminal is inserted, the lid is held by hand when it is desired to increase the lid opening angle. Since it is necessary, the operability of the insertion is poor, there is a problem that there is no moderation feeling due to the open / closed state of the lid, and the operational feeling is also poor. Furthermore, since the lock claw is provided, there is a problem that the design property when the lid is opened is poor, and the manufacturing cost of the lid mold is increased. For this reason, even if the lid of the prior art described in Patent Document 1 is applied to the lid of a plug terminal box for in-vehicle use, it is difficult to meet the above request.
本発明は、蓋のある車載用プラグ端子箱において、簡便な構造で接続端子の挿入性の向上を図るとともに蓋の開閉操作感の向上を図ることを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide an in-vehicle plug terminal box with a lid that improves the insertability of connection terminals with a simple structure and improves the feeling of opening and closing the lid.

図３、図４を参照しながら突起２１の第１、第２の当たり面２２，２３と、アーム３１の第１、第２の押しつけ面３２，３３と、ストッパ４１の係止面４２と、ハウジング１１の上面１１ａとの軸１５の周りの角度位置の関係について説明する。図３は蓋１６の閉状態を示し、図４は蓋１６の開状態を示している。 With reference to FIGS. 3 and 4, the first and second contact surfaces 22 and 23 of the protrusion 21, the first and second pressing surfaces 32 and 33 of the arm 31, the locking surface 42 of the stopper 41, The relationship of the angular position around the axis 15 with the upper surface 11a of the housing 11 will be described. FIG. 3 shows the closed state of the lid 16, and FIG. 4 shows the opened state of the lid 16.
図３に示すように、蓋１６がフランジ１４に当たって図示しない開口１３を覆う閉状態においては、突起２１の第１の当たり面２２はアーム３１の第１の押し付け面３２に当たっている。より詳細には、各面２２，３２の内、第１の当たり面２２の軸１５から半径方向に最も遠い第１の当たり点２２ａと、第１の当たり点２２ａが接する第１の押しつけ面３２にある第１の押し付け点３２ａとが接している。また、蓋１６が閉状態では、蓋１６のフランジ１４に当たる面に平行で軸１５の中心を通る線１６ａと、フランジ１４の中心線１４ａとは同一位置となっている。そして、蓋１６の第１の押し付け面３２からフランジ１４の面までの軸１５周りの角度は、第１の押し付け点３２ａからフランジ１４の中心線１４ａまでの角度となり、第１の当たり面２２から蓋１６のフランジ１４に接する面までの間の軸１５周りの角度は、第１の当たり点２２ａから線１６ａまでの軸１５周りの角度となる。蓋１６が閉状態では、この２つの角度は同一角度であり、図３(ｂ)に示す角度α３となっている。 As shown in FIG. 3, in the closed state where the lid 16 hits the flange 14 and covers the opening 13 (not shown), the first contact surface 22 of the protrusion 21 contacts the first pressing surface 32 of the arm 31. More specifically, of each of the surfaces 22 and 32, a first contact point 22a farthest in the radial direction from the axis 15 of the first contact surface 22 and a first pressing surface 32 in contact with the first contact point 22a. And the first pressing point 32a in contact with each other. When the lid 16 is in the closed state, the line 16a passing through the center of the shaft 15 parallel to the surface of the lid 16 that contacts the flange 14 and the center line 14a of the flange 14 are at the same position. The angle around the axis 15 from the first pressing surface 32 of the lid 16 to the surface of the flange 14 is an angle from the first pressing point 32a to the center line 14a of the flange 14, and from the first contact surface 22 The angle around the axis 15 between the surface of the lid 16 that contacts the flange 14 is the angle around the axis 15 from the first contact point 22a to the line 16a. The lid 16 is closed, the two angles are the same angles, has an angle alpha 3 shown in FIG. 3 (b).
同様に、第２の押し付け面３３からハウジング１１の上面１１ａまでの軸１５周りの角度は、第２の押しつけ面３３にある蓋１６が開状態の場合に第２の当たり面２３の軸１５から半径方向に最も遠い第２の当たり点２３ａが接する第２の押し付け点３３ａからストッパ４１の係止面４２にある軸１５から半径方向に最も遠い係止点４２ａが接するハウジング１１の上面１１ａの接点１１ｂまでの軸１５周りの角度となる。図３に示すように、第２の押し付け点３３ａから接点１１ｂまでの蓋１６の開方向に向かう軸１５周りの角度は角度β１である。また、第２の当たり面２３からストッパ４１のハウジング１１の上面１１ａに接する係止面４２までの軸１５周りの角度は、第２の当たり点２３ａからストッパ４１の係止点４２ａまでの軸１５周りの角度となる。図３に示すように、第２の当たり点２３ａから係止点４２ａまでの蓋１６の開方向に向かう軸１５周りの角度は角度β２である。 Similarly, the angle around the axis 15 from the second pressing surface 33 to the upper surface 11a of the housing 11 is from the axis 15 of the second contact surface 23 when the lid 16 on the second pressing surface 33 is open. The contact point of the upper surface 11a of the housing 11 with which the locking point 42a farthest in the radial direction from the shaft 15 on the locking surface 42 of the stopper 41 contacts the second pressing point 33a with which the second contact point 23a farthest in the radial direction contacts. It becomes an angle around the axis 15 up to 11b. As shown in FIG. 3, the angle around the axis 15 toward the opening direction of the lid 16 from the second pressing point 33a to the contact point 11b is the angle beta 1. The angle around the shaft 15 from the second contact surface 23 to the locking surface 42 that contacts the upper surface 11a of the housing 11 of the stopper 41 is the axis 15 from the second contact point 23a to the locking point 42a of the stopper 41. It becomes the surrounding angle. As shown in FIG. 3, the angle around the axis 15 toward the opening direction of the lid 16 from the second abutment point 23a to anchor point 42a is the angle beta 2.
図４に示すように、蓋１６が開状態にある場合には、第２の当たり点２３ａと第２の押し付け点３３ａとが接し、係止点４２ａと接点１１ｂとが接している。そして、第２の当たり点２３ａ、第２の押し付け点３３ａから係止点４２ａ、接点１１ｂまでの蓋１６の開方向に向かう軸１５周りの角度はいずれも角度β３となっている。 As shown in FIG. 4, when the lid 16 is in the open state, the second contact point 23a and the second pressing point 33a are in contact with each other, and the locking point 42a and the contact point 11b are in contact with each other. The second per point 23a, and has a second pressing point 33a from anchor point 42a, the shaft 15 an angle beta 3 any angle around toward the opening direction of the lid 16 to contact 11b.
図４に示すように、蓋１６が開状態では、第１の押し付け点３２ａと第１の当たり点２２ａとは離れた位置にある。そして、第１の押し付け点３２ａからフランジ１４の中心線１４ａまでの蓋１６の開方向に向かう軸１５周りの角度は角度α１で、第１の当たり点２２ａから蓋１６のフランジ１４への当たり面と平行な線１６ａまでの蓋１６の開方向に向かう軸１５周りの角度は角度α２となっている。 As shown in FIG. 4, when the lid 16 is in the open state, the first pressing point 32a and the first contact point 22a are located at a distance. The angle around the axis 15 toward the opening direction of the lid 16 from the first pressing point 32a to the center line 14a of the flange 14 at an angle alpha 1, per from a first per point 22a to the flange 14 of the lid 16 angles around the axis 15 toward the opening direction of the lid 16 to the plane parallel to the line 16a has a angle alpha 2.
図３、図４に示すように、ストッパ４１の係止点４２ａからハウジング１１の上面１１ａにある接点１１ｂまでの蓋１６の開方向に向かう軸１５周りの角度は角度γであり、この角度γは蓋１６のフランジ１４からの開き角度であり、図４(ｂ)に示すように、フランジ１４の中心線１４ａから第１の当たり点２２ａまでの蓋１６の開方向に向かう軸１５周りの角度と等しくなっている。また、図３(ｂ)に示すように、第２の当たり点２３ａから第２の押し付け点３３ａまでの蓋１６の開方向に向かう軸１５周りの角度も角度γとなっている。 As shown in FIGS. 3 and 4, the angle around the axis 15 in the opening direction of the lid 16 from the locking point 42a of the stopper 41 to the contact 11b on the upper surface 11a of the housing 11 is an angle γ. Is the opening angle of the lid 16 from the flange 14, and as shown in FIG. 4B, the angle around the axis 15 from the center line 14a of the flange 14 to the first contact point 22a toward the opening direction of the lid 16. It is equal to. Further, as shown in FIG. 3B, the angle around the axis 15 from the second contact point 23a to the second pressing point 33a in the opening direction of the lid 16 is also an angle γ.
アーム３１はフランジ１４と一体に弾性体である樹脂で成形されている。また、同様に蓋１６とブッシュ２０と突起２１とストッパ４１とは弾性体である樹脂によって一体成形されている。 The arm 31 is molded integrally with the flange 14 from an elastic resin. Similarly, the lid 16, the bush 20, the protrusion 21, and the stopper 41 are integrally formed of an elastic resin.
以上説明したように構成された車載用プラグ端子箱１０の蓋１６の開閉動作について説明する。図４に示すように、蓋１６が開状態においては、第１の押し付け点３２ａからフランジ１４の中心線１４ａまでの角度α１は第１の当たり点２２ａから線１６ａまでの角度α２よりも大きくなっている。そして、図３に示すように、蓋１６がフランジ１４の面に接するように蓋１６を閉めた場合、第１の当たり点２２ａと第１の押し付け点３２ａとが接し、中心線１４ａと線１６ａとは重なる。このため、第１の押し付け点３２ａは第１の当たり点２２ａを図３(ｂ)に示す矢印の方向、すなわち蓋１６の閉方向に向かって押し付けることとなる。第１の押し付け点３２ａのあるアーム３１、第１の当たり点２２ａのある突起２１はそれぞれ樹脂製であることから、互いに変形し、角度α１、角度α２は、角度α１よりも小さく角度α２よりも大きい共通の角度α３となる。そしてアーム３１の弾性力によって第１の押し付け点３２ａは第１の当たり点２２ａを蓋１６の閉方向に押し付け保持し、蓋１６をフランジ１４に接した閉状態に保持することができる。 The opening / closing operation | movement of the lid | cover 16 of the vehicle-mounted plug terminal box 10 comprised as demonstrated above is demonstrated. As shown in FIG. 4, in the lid 16 is opened, the angle alpha 1 of the first pressing point 32a to the center line 14a of the flange 14 than the angle alpha 2 to the line 16a from the first per point 22a It is getting bigger. As shown in FIG. 3, when the lid 16 is closed so that the lid 16 contacts the surface of the flange 14, the first contact point 22a and the first pressing point 32a are in contact with each other, and the center line 14a and the line 16a And overlap. Therefore, the first pressing point 32a presses the first contact point 22a in the direction of the arrow shown in FIG. 3B, that is, in the closing direction of the lid 16. Since the arm 31 having the first pressing point 32a and the projection 21 having the first contact point 22a are made of resin, they are deformed to each other, and the angle α 1 and the angle α 2 are smaller than the angle α 1. a common angle alpha 3 is larger than alpha 2. The first pressing point 32 a can press and hold the first contact point 22 a in the closing direction of the lid 16 by the elastic force of the arm 31, and can hold the lid 16 in a closed state in contact with the flange 14.
一方、図３に示すように、蓋１６が閉状態においては、第２の押し付け点３３ａからハウジング１１の上面１１ａにある接点１１ｂまでの角度β１は、第２の当たり点２３ａからストッパ４１の係止点４２ａまでの角度β２よりも小さくなっている。そして、蓋１６が開くと、第２の当たり点２３ａは第２の押し付け点３３ａに接し、係止点４２ａはハウジング１１の上面１１aにある接点１１ｂに接する。このため、第２の押し付け点３３ａは第２の当たり点２３ａを図３（ｂ）に示す矢印の方向、すなわち蓋１６の開方向に向かって押し付ける。先に説明した蓋１６の閉状態と同様、アーム３１、突起２１はそれぞれ樹脂製であることから、互いに変形し、角度β１、角度β２は、角度β１よりも大きく角度β２よりも小さい共通の角度β３となる。そして、アーム３１の弾性力によって第２の押し付け点３３ａは第２の当たり点２３ａを蓋１６の開方向に押し付け、ストッパ４１の係止点４２ａをハウジング１１の上面１１ａにある接点１１ｂに押し付け保持することができる。このため、蓋１６を開けた場合に蓋１６を手で保持しなくとも蓋１６を開状態に保持した状態で接続端子の差し込みを行うことができ、接続端子の挿入性を向上させることができるという効果を奏する。 On the other hand, as shown in FIG. 3, the lid 16 is closed, the angle beta 1 of the second pressing point 33a to the contact 11b on the top 11a of the housing 11, the stopper 41 from the second abutment point 23a engaging point is smaller than the angle β 2 of up to 42a. When the lid 16 is opened, the second contact point 23 a comes into contact with the second pressing point 33 a, and the locking point 42 a comes into contact with the contact 11 b on the upper surface 11 a of the housing 11. Therefore, the second pressing point 33a presses the second contact point 23a in the direction of the arrow shown in FIG. As in the closed state of the lid 16 described above, the arm 31 and the protrusion 21 are made of resin, so that they deform each other, and the angle β 1 and the angle β 2 are larger than the angle β 1 and larger than the angle β 2. A small common angle β 3 . The second pressing point 33a presses the second contact point 23a in the opening direction of the lid 16 by the elastic force of the arm 31, and the locking point 42a of the stopper 41 is pressed against the contact 11b on the upper surface 11a of the housing 11. can do. For this reason, when the lid 16 is opened, the connection terminal can be inserted in a state where the lid 16 is held in the open state without holding the lid 16 by hand, and the insertion property of the connection terminal can be improved. There is an effect.
本実施形態では、蓋１６の開角度は角度γであり、ストッパ４１、突起２１、アーム３１の配置を調整することによってその角度を任意に設定することができる。このため、図２(ｂ)に示したプラグ端子１２の大きさに応じて、蓋１６の開角度を大きくして接続プラグの挿入のためのスペースを確保することができ、接続プラグの接続性を向上させることができる。また、蓋１６のフランジ１４に接する面から突出するものがない構成となっているので、接続端子の挿入の際に干渉するものが無く、挿入性を向上させることができるという効果を奏する。更に、蓋１６のフランジ１４に接する面からロック爪などを突出させることが必要なくなるので、蓋１６の開状態における意匠性を向上させることができると共に金型のコストを低減することができるという効果を奏する。 In the present embodiment, the opening angle of the lid 16 is an angle γ, and the angle can be arbitrarily set by adjusting the arrangement of the stopper 41, the protrusion 21, and the arm 31. Therefore, according to the size of the plug terminal 12 shown in FIG. 2B, the opening angle of the lid 16 can be increased to ensure a space for inserting the connection plug, and the connection plug connectivity Can be improved. In addition, since there is no structure that protrudes from the surface of the lid 16 that contacts the flange 14, there is nothing that interferes when the connection terminal is inserted, and the insertability can be improved. Furthermore, since it becomes unnecessary to project a lock claw etc. from the surface which contacts the flange 14 of the lid | cover 16, the design property in the open state of the lid | cover 16 can be improved and the cost of a metal mold | die can be reduced. Play.
蓋１６の開閉動作の途中では、突起２１の滑り面２４，２５が図２(ｃ)に示すアーム３１の先端３５に接するが、アーム３１は図２(ｃ)に示す切り欠き３４によって幅の狭い平板の片持ち梁の形状となっていることと、弾性体である樹脂によって構成されていることから、蓋１６の開閉方向にたわみ、蓋１６をスムースに開閉することができる。また、蓋１６を閉状態から開く際には、第１の当たり点２２ａがアーム３１の先端３５を乗り越えるだけの力を蓋１６の開方向に向って加えることが必要となる。そして、蓋１６を閉状態とするには第２の当たり点２３ａがアーム３１の先端３５を乗り越えるだけの力を蓋１６の閉方向に向かって加えることが必要となる。このため、蓋１６の開動作の際には蓋１６の開き始めと開き終わりにおいて節度感が発生し、蓋１６の開操作感を向上させることができる。また、蓋１６の閉動作の際も同様に、蓋１６の閉まり始めと閉まり終わりにおいて節度感が発生し、蓋１６の閉操作感を向上させることがでる。これによって、蓋１６の開閉の操作感の向上を図ることが出来るという効果を奏する。 During the opening / closing operation of the lid 16, the sliding surfaces 24 and 25 of the protrusion 21 are in contact with the tip 35 of the arm 31 shown in FIG. 2 (c). The arm 31 is widened by the notch 34 shown in FIG. 2 (c). Since it has a narrow flat cantilever shape and is made of an elastic resin, it can bend in the opening and closing direction of the lid 16 and the lid 16 can be smoothly opened and closed. Further, when the lid 16 is opened from the closed state, it is necessary to apply a force sufficient for the first contact point 22 a to get over the tip 35 of the arm 31 in the opening direction of the lid 16. In order to close the lid 16, it is necessary to apply a force sufficient for the second contact point 23 a to get over the tip 35 of the arm 31 in the closing direction of the lid 16. Therefore, when the lid 16 is opened, a feeling of moderation occurs at the beginning and end of opening of the lid 16, and the feeling of opening the lid 16 can be improved. Similarly, when the lid 16 is closed, a feeling of moderation occurs at the beginning and end of closing of the lid 16, and the feeling of closing operation of the lid 16 can be improved. As a result, it is possible to improve the operational feeling of opening and closing the lid 16.
以上述べたように、本実施形態は、簡便な構造で接続端子の挿入性を向上させることができると共に、蓋の開閉操作の操作感を向上させることができるという効果を奏する。 As described above, the present embodiment has an effect that the insertion property of the connection terminal can be improved with a simple structure and the operational feeling of the lid opening / closing operation can be improved.
