Description

【０００１】
【発明の属する技術分野】
この発明は、たとえば蛍光灯用照明器具に適用される回転式ソケットに関するものである。
【０００２】
【従来の技術】
従来例を図１９に示す。すなわち、回転子１００の壁部１０１に一定角度間隔でランプピン挿通溝１０２を含む複数の係合凹部１０３を設け、ソケット本体には回転子の係合凹部にはまり合う係合凸部を設けたソケットは知られている（例えば特公昭63-29392号公報）。
【０００３】
【発明が解決しようとする課題】
しかし、回転子１００の係合凹部１０３には弾性変形機能がなく、また回転子１００の回動操作に必要なランプ着脱トルクが係止位置により一定でないという欠点があった。
したがって、この発明の目的は、ランプ着脱位置が回転子の回動操作を利用したクリック止め機構により、操作感触とクリック音により９０度ごとに確認が容易になる回転式ソケットを提供することである。
【０００４】
【課題を解決するための手段】
請求項１記載の回転式ソケットは、前面に開口を有し、ランプのランプピンに当接する導電接触子を前記開口の内側に有し、前記ランプピンを前記開口の内側に挿入させるランプピン挿入溝を側面から前記開口に連通して形成したソケット本体と、
このソケット本体の前記開口を覆って回転可能に設けられるものであって、略全周側面にわたって略円筒状の壁部を有し、ランプ非装着状態で前記ランプピン挿入溝に整合するランプピン挿通溝を、前記壁部から前面に連続して少なくとも回転子の回転中心を越えた中央部まで形成した回転子とを備え、
前記ランプピンを前記ランプピン挿通溝に挿通した状態で前記ランプピンを前記回転子とともに略９０度回転させて前記ランプピンを前記導電接触子に接触させる回転式ソケットにおいて、
前記回転子の壁部には略９０度間隔で前記ランプピン挿通溝を含む４箇所の残り３箇所に切欠状の係合凹部を設け、前記ソケット本体には前記回転子の回転により前記係合凹部および前記ランプピン挿通溝に嵌まり合う係合凸部を設け、
かつ、前記係合凹部と前記係合凸部との係合状態からの離脱トルクを、前記ランプピンの挿入または離脱となる位置でのトルクがランプ装着位置でのトルク以上となるようにし、
さらに、前記係合凹部の幅がランプピン挿通溝の幅より狭く形成され、前記係合凸部は前記係合凹部の幅に適合させて前記回転子の回転中心に関し対称位置に２箇所形成し、前記回転子の回転中心に関し前記ランプピン挿通溝に対向する前記係合凹部は、前記係合凸部との係合長さが他の前記係合凹部の略２倍であるように形成したものである。
【０００５】
請求項１記載の回転式ソケットによれば、回転子を回してランプピン挿通溝をソケット本体のランプピン挿入溝に整合させると、ランプピンを回転子のランプピン挿通溝内に出し入れすることができる。ランプピンをランプピン挿通溝内の回転装着位置に移動させた後、ランプを回すと回転子も一体に回転する。そのとき、２本のランプピンは回転子のランプピン挿通溝からソケット本体内に突出しているから、導電接触子の接触面に当接しこれを弾性変形させ、同時に係合凸部が回転子の内壁へも弾性的に押付けながら略９０度回転した位置で、係合凸部が回転子の係合凹部を押し広げながら係止する。この係合凸部が係合凹部にはまり込むときに弾性変形状態から係合凸部と回転子の係合凹部が原位置へ復帰する際にクリック音を発生させ、ランプピンは導通状態となる。この係合状態からさらにどちらの方向でも回転させる場合にランプを回転させるために必要な離脱トルクは、ランプピンが導電接触子への接触から離脱するトルクが回転子とソケット本体との係合状態からの離脱トルクに追加されるため、ランプピンの装着トルクよりも大きくなる。そのため、ランプが装着しやすく安定した導通状態を操作感触とクリック音により確認することが容易にできる。
【０００６】
すなわち、回転子の係合凹部の形状を従来の縦溝から変更したことにより、円筒状の壁部の肉厚を薄くすることができ、ソケット本体の係合凸部と同等の弾性変形が可能となすことができるため、係合凹部と係合凸部が嵌合する際のたわみ量を大きくできるので、明快なクリック感触とクリック音を出すことができる。また９０度ごとにランプの着脱位置を設けたことで、従来のように３０度または４５度毎に比べ視覚的にも係止位置の確認が容易になる。
【０００７】
さらにランプの着脱操作において、ランプ装着状態から、ランプを回転させる離脱トルクはソケット本体の係合凸部と回転子の係合凹部の回動操作に必要なトルクと、ランプピンと導電接触子の係合部からの離脱トルクを利用することで、ランプ装着位置での回転トルク以上になるようにでき、ランプが装着しやすく安定した導通状態を得られる。
【００１０】
さらに、前記係合凹部の幅がランプピン挿通溝の幅より狭く形成され、前記係合凸部は前記係合凹部の幅に適合させて前記回転子の回転中心に関し対称位置に２箇所形成し、前記回転子の回転中心に関し前記ランプピン挿通溝に対向する前記係合凹部は、前記係合凸部との係合長さが他の前記係合凹部の略２倍であるように形成したため、ランプピン挿通溝を係合凹部として利用できない場合に、回転子の回動操作に必要なトルクを、略９０度毎のどの係合状態から回転させてもほぼ一定にできる。
請求項２記載の回転式ソケットは、前面に開口を有し、ランプのランプピンに当接する導電接触子を前記開口の内側に有し、前記ランプピンを前記開口の内側に挿入させるランプピン挿入溝を側面から前記開口に連通して形成したソケット本体と、
このソケット本体の前記開口を覆って回転可能に設けられるものであって、略全周側面にわたって略円筒状の壁部を有し、ランプ非装着状態で前記ランプピン挿入溝に整合するランプピン挿通溝を、前記壁部から前面に連続して少なくとも回転子の回転中心を越えた中央部まで形成した回転子とを備え、
前記ランプピンを前記ランプピン挿通溝に挿通した状態で前記ランプピンを前記回転子とともに略９０度回転させて前記ランプピンを前記導電接触子に接触させる回転式ソケットにおいて、
前記回転子の壁部には略９０度間隔で前記ランプピン挿通溝を含む４箇所の残り３箇所に切欠状の係合凹部を設け、前記ソケット本体には前記回転子の回転により前記係合凹部および前記ランプピン挿通溝に嵌まり合う係合凸部を設け、
かつ、前記係合凹部と前記係合凸部との係合状態からの離脱トルクを、前記ランプピンの挿入または離脱となる位置でのトルクがランプ装着位置でのトルク以上となるようにし、
さらに、前記係合凹部の幅が前記ランプピン挿通溝の幅より狭く形成され、前記係合凸部は前記係合凹部の幅に適合させて前記回転子の回転中心に関し対称位置およびそれらの間の一方の３箇所に形成し、前記回転子の回転中心に関し前記ランプピン挿通溝に対向する前記係合凹部は、前記係合凸部との係合長さが他の前記係合凹部の略２倍であるように形成したものである。
【００１１】
請求項２記載の回転式ソケットによれば、請求項１と同様な効果のほか、前記係合凹部の幅が前記ランプピン挿通溝の幅より狭く形成され、前記係合凸部は前記係合凹部の幅に適合させて前記回転子の回転中心に関し対称位置およびそれらの間の一方の３箇所に形成し、前記回転子の回転中心に関し前記ランプピン挿通溝に対向する前記係合凹部は、前記係合凸部との係合長さが他の前記係合凹部の略２倍であるように形成したため、ランプピン挿通溝を係合凹部として利用できない場合に、ランプ着脱位置での回転トルクの変化量を大きくできるからより明確な操作感が得られ、その位置確認が容易になる。
【００１２】
【発明の実施の形態】
この発明の第１の実施の形態を図１から図６により説明する。すなわち、この回転式ソケットは、ソケット本体１と、回転子２とを有する。
ソケット本体１は、前面に開口３を有し、ランプのランプピンＰに当接する導電接触子４を開口３の内側に有し、ランプピンＰを開口３の内側に挿入させるランプピン挿入溝５を側面から開口３に連通して形成している。またソケット本体１には回転子２の係合凹部６に嵌まり合う係合凸部１３を設けている。
【００１３】
実施の形態ではソケット本体１が熱可塑性合成樹脂により形成され、器具本体取付部７と、この器具本体取付部７に取付けられた有底の筒状部８からなり、筒状部８の端部を開口３とし、筒状部８にランプ挿入溝５を形成している。筒状部８の底部中央に割り２３付きの連結用筒部９を設け、その先端の外周縁に外向きつば状の爪部１０を形成している。連結用筒部９の割り２３を挾みランプピン挿入溝５と連結用筒部９を結ぶ方向と直交する方向の周面に、図３に示すように導電接触子４の中間部が当接され、導電接触子４の両端を筒状部８の底部に設けた例えばリブ状の突起等の位置決め部１２により位置決めしている。また筒部９を中心とした半径方向の導電接触子４よりも外方に所定の距離離れた位置およびランプピン挿入溝５と筒部９に関して反対側にそれぞれ回転子２の内周面に摺接する例えばリブとなる円弧板状の突出部１４ａ〜１４ｃを設け、突出部１４ａ、１４ｂの摺接面となる外面にそれぞれ係合凸部１３を設けている。すなわち、係合凸部１３はランプピン挿通溝１１以外の係合凹部６の幅に適合させて回転子２の回転中心に関し対称位置に２箇所形成している。導電接触子４はその中間部の筒部９に当接した位置にランプピンＰを位置決めする凹部４ａを形成している。４ｂは導電接触子４の端子部であり、電線を速結接続する。２２は防水リング用の雄ねじである。
【００１４】
回転子２は、ソケット本体１の開口３を覆って回転可能に設けられるものであって、略全周側面にわたって略円筒状の壁部１９を有し、ランプ非装着状態でランプピン挿入溝５に整合するランプピン挿通溝１１を、壁部１９から前面２ａに連続して少なくとも回転子２の回転中心を越えた中央部まで形成している。回転子２の壁部１９には略９０度間隔でランプピン挿通溝１１を含む４箇所の残り３箇所に係合凹部６、例えば切欠状の係合凹部６を設けている。実施の形態の回転子２は、熱可塑性合成樹脂により形成され、導電接触子４を覆い、前面２ａの中央に筒部９に嵌合する筒部１６を有し、筒部１６の端部内周縁に爪部１０に係合する抜止め部１７を形成して、回転子２をソケット本体１に樹脂弾性を利用して回転自在に取付けている。回転子２を取付けた状態で回転子２の壁部１９の内周面に突出部１４ａ〜１４ｃの外周面が当接し、係合凸部１３により壁部１９を外方に弾性変形させ、回転子２の所定の回転位置で係合凹部６に係合凸部１３が弾性的に係合する。
【００１５】
この実施の形態の回転式ソケットは、ランプピンＰをランプピン挿通溝１１に挿通した状態でランプピンＰを回転子２とともに略９０度回転させてランプピンＰを導電接触子４に接触させる。そしてこのとき、係合凹部６およびランプピン挿通溝１１と係合凸部１３との係合状態からの離脱トルクを、ランプピンＰの挿入または離脱となる位置でのトルクがランプ装着位置でのトルク以上となるようにしている。
【００１６】
この実施の形態によれば、回転子２を回してランプピン挿通溝１１をソケット本体１のランプピン挿入溝５に整合させると、ランプピンＰを回転子２のランプピン挿通溝１１内に出し入れすることができる。ランプピンＰをランプピン挿通溝１１内の回転装着位置に移動させた後、ランプ２１を回すと回転子２も一体に回転する。そのとき、２本のランプピンＰは回転子２のランプピン挿通溝１１からソケット本体１内に突出しているから、導電接触子４の接触面に当接しこれを弾性変形させ、同時に係合凸部１３が回転子２の壁部１９へも弾性的に押付けながら略９０度回転した位置で、ランプピンＰは導電接触子４の係合凹部４ａに入るとともに、係合凸部１３が回転子２の係合凹部６を押し広げながら係止する。この係合凸部１３が係合凹部６およびランプピン挿通溝１１にはまり込むときに壁部１９の弾性変形状態から係合凸部１３と回転子２の係合凹部６またはランプピン挿通溝１１が原位置へ復帰する際にクリック音を発生させ、ランプピンＰは導通状態となる。この係合状態からさらにどちらの方向でもランプピンＰを回転させる場合に、ランプ２１を回転させるために必要な離脱トルクは、ランプピンＰが導電接触子４の係合凹部４ａから離脱するトルクが回転子２とソケット本体１との係合状態からの離脱トルクに追加されるため、ランプピンＰの装着トルクよりも大きくなる。そのため、ランプ２１が装着しやすく安定した導通状態を操作感触とクリック音により確認することが容易にできる。
【００１７】
この場合、回転子２の係合凹部６の形状を従来の縦溝から変更したことにより、円筒状の壁部１９の肉厚を薄くすることができ、ソケット本体１の係合凸部１３のある突出部１４ａ，１４ｂと同等の弾性変形が可能となったため、係合凹部６と係合凸部１３が嵌合する際のたわみ量を大きくできるので、明快なクリック感触とクリック音を出すことができるようになった。
【００１８】
また９０度ごとにランプ２１の着脱位置を設けたことで、従来のように３０度または４５度毎に比べ視覚的にも係止位置の確認が容易になった。
さらにランプ２１の着脱操作において、ランプ装着状態から、ランプ２１を回転させる離脱トルクはソケット本体１の係合凸部１３と回転子２の係合凹部６の回動操作に必要なトルクと、ランプピンＰと導電接触子４の係合部４ａからの離脱トルクを利用することで、ランプ装着位置での回転トルク以上になるようにでき、ランプ２１が装着しやすく安定した導通状態を得られる。
【００１９】
この発明の第２の実施の形態を図７に示す。すなわち、第１の実施の形態において、４箇所に配置した係合凹部６およびランプピン挿通溝１１のうちランプピン挿通溝１１以外のものの幅がランプピン挿通溝１１の幅にほぼ等しく形成されている。
この実施の形態によれば、回転子２の回動操作に必要な回転トルクのうち導電接触子４の係合部４ａより回転させるのに必要なトルクを除いたトルクを略９０度毎のどの係合状態から回転させてもほぼ同じにできる。
【００２０】
その他は第１の実施の形態と同様である。
この発明の第３の実施の形態を図８から図１３に示す。すなわち、第１の実施の形態において、４箇所に配置した回転子２の係合凹部６およびランプピン挿通溝１１のうち、ランプピン挿通溝１１以外のものはその幅がランプピン挿通溝１１の幅より狭く形成され、ソケット本体１の係合凸部１３は回転子２のランプピン挿通溝１１以外の係合凹部６の幅に適合させて、第１の実施の形態と同様に回転子２の回転中心に関し対称位置に２箇所形成し、回転子２の回転中心に関しランプピン挿通溝１１に対向する１箇所の係合凹部６（６ａ）は、係合凸部１３との係合長さが他の係合凹部６の略２倍であるように形成している。実施の形態では、壁部１９の縁部より垂下片１９ａを一体に垂下し、垂下片１９ａと壁部１９とにまたがる切欠状に係合凹部６ａを形成して所定の長さを確保している。
【００２１】
この実施の形態によれば、ランプ挿入位置からランプ装着位置（９０度回転）への回動操作時は、回転子２の２箇所の係合凹部６とソケット本体１の２箇所の係合凸部１３の嵌合状態からの離脱であり、そこからランプ装着位置（９０度回転位置）へ係合する時は、回転子２のランプピン挿通溝１１に対向する係合凹部６ａの１箇所と、ソケット本体１のどちらか一方の係合凸部１３への係合となる。したがって、ランプピン挿通溝１１を係合凹部６として利用できない場合に、回転子２の回動操作に必要なトルクを、略９０度毎のどの係合状態から回転させてもほぼ一定にできる。
【００２２】
その他は、第１の実施の形態と同様である。
この発明の第４の実施の形態を図１４から図１８に示す。すなわち、第３の実施の形態において、ソケット本体１の係合凸部１３は、回転子２のランプピン挿通溝１１以外の係合凹部６の幅に適合させて、回転子２の回転中心に関し対称位置およびそれらの間の一方の３箇所に形成している。すなわち、突出部１４ａ、１４ｂの係合凸部１３に加えて、突出部１４ｃの外面にも係合凸部１３を形成している。
【００２３】
この実施の形態によれば、ランプピン挿通溝を係合凹部として利用できない場合に、ランプ着脱位置での回転トルク変化量を大きくできるからより明確な操作感が得られ、その位置確認が容易になる。
その他は、第３の実施の形態と同様である。
【００２４】
【発明の効果】
請求項１記載の回転式ソケットによれば、回転子の係合凹部の形状を従来の縦溝から変更したことにより、円筒状の壁部の肉厚を薄くすることができ、ソケット本体の係合凸部と同等の弾性変形が可能となすことができるため、係合凹部と係合凸部が嵌合する際のたわみ量を大きくできるので、明快なクリック感触とクリック音を出すことができる。また９０度ごとにランプの着脱位置を設けたことで、従来のように３０度または４５度毎に比べ視覚的にも係止位置の確認が容易になる。
【００２５】
さらにランプの着脱操作において、ランプ装着状態から、ランプを回転させる離脱トルクはソケット本体の係合凸部と回転子の係合凹部の回動操作に必要なトルクと、ランプピンと導電接触子の係合部からの離脱トルクを利用することで、ランプ装着位置での回転トルク以上になるようにでき、ランプが装着しやすく安定した導通状態を得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a rotary socket applied to, for example, a fluorescent lamp lighting fixture.
[0002]
[Prior art]
A conventional example is shown in FIG. That is, a socket in which a plurality of engaging recesses 103 including lamp pin insertion grooves 102 are provided at a predetermined angular interval on the wall 101 of the rotor 100, and an engaging protrusion that fits into the engaging recess of the rotor is provided on the socket body. Are known (for example, Japanese Patent Publication No. 63-29392).
[0003]
[Problems to be solved by the invention]
However, the engaging recess 103 of the rotor 100 does not have an elastic deformation function, and the lamp attaching / detaching torque necessary for the rotating operation of the rotor 100 is not constant depending on the locking position.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rotary socket in which a lamp attachment / detachment position can be easily confirmed every 90 degrees by an operation feeling and a click sound by a click stop mechanism using a rotation operation of a rotor. .
[0004]
[Means for Solving the Problems]
The rotary socket according to claim 1, wherein an opening is provided on a front surface, a conductive contact that abuts on a lamp pin of a lamp is provided inside the opening, and a lamp pin insertion groove that allows the lamp pin to be inserted inside the opening is provided on a side surface. A socket body formed in communication with the opening from
A lamp pin insertion groove that is rotatably provided to cover the opening of the socket body, has a substantially cylindrical wall portion over substantially the entire circumferential side surface, and aligns with the lamp pin insertion groove when the lamp is not mounted. A rotor formed continuously from the wall portion to the front surface to a central portion at least exceeding the rotation center of the rotor,
In the rotary socket in which the lamp pin is rotated approximately 90 degrees together with the rotor while the lamp pin is inserted into the lamp pin insertion groove, and the lamp pin is brought into contact with the conductive contact,
The rotor wall is provided with notch-like engaging recesses at the remaining three locations including the lamp pin insertion groove at intervals of approximately 90 degrees, and the engagement recesses are formed in the socket body by the rotation of the rotor. And an engaging projection that fits into the lamp pin insertion groove ,
And, the separation torque from the engagement state between the engagement recess and the engagement projection is set so that the torque at the position where the lamp pin is inserted or removed is equal to or greater than the torque at the lamp mounting position.
Further, the width of the engaging recess is formed to be narrower than the width of the lamp pin insertion groove, and the engaging protrusion is formed at two symmetrical positions with respect to the rotation center of the rotor in conformity with the width of the engaging recess, The engagement recess facing the lamp pin insertion groove with respect to the rotation center of the rotor is formed so that the engagement length with the engagement protrusion is approximately twice that of the other engagement recess. is there.
[0005]
According to the rotary socket of the first aspect, when the rotor is rotated to align the lamp pin insertion groove with the lamp pin insertion groove of the socket body, the lamp pin can be inserted into and removed from the lamp pin insertion groove of the rotor. After the lamp pin is moved to the rotation mounting position in the lamp pin insertion groove, when the lamp is turned, the rotor also rotates integrally. At this time, since the two lamp pins protrude into the socket body from the lamp pin insertion groove of the rotor, they abut against the contact surface of the conductive contact member and elastically deform it, and at the same time, the engaging convex portion moves to the inner wall of the rotor. In addition, the engaging convex portion engages the engaging concave portion of the rotor while expanding the engaging concave portion at a position rotated approximately 90 degrees while being elastically pressed. A click sound is generated when the engaging convex portion and the engaging concave portion of the rotor return to the original position from the elastically deformed state when the engaging convex portion fits into the engaging concave portion, and the lamp pin becomes conductive. When the lamp is further rotated in either direction from this engaged state, the release torque necessary for rotating the lamp is the torque at which the lamp pin is released from the contact with the conductive contact from the engaged state between the rotor and the socket body. Therefore, it becomes larger than the mounting torque of the lamp pin. Therefore, it is easy to mount the lamp and it is possible to easily confirm a stable conduction state by an operation feeling and a click sound.
[0006]
In other words, by changing the shape of the engaging recess of the rotor from the conventional longitudinal groove, the wall thickness of the cylindrical wall can be reduced, and the elastic deformation equivalent to the engaging protrusion of the socket body is possible Since the amount of deflection at the time when the engaging concave portion and the engaging convex portion are fitted can be increased, a clear click feeling and click sound can be produced. Further, by providing the lamp attachment / detachment position every 90 degrees, it becomes easier to visually confirm the locking position as compared with every 30 degrees or 45 degrees as in the prior art.
[0007]
Further, in the lamp attaching / detaching operation, the detachment torque for rotating the lamp from the lamp mounting state is the torque required for the rotating operation of the engaging convex part of the socket body and the engaging concave part of the rotor, and the relationship between the lamp pin and the conductive contact. By using the separation torque from the joint, it can be made to be equal to or higher than the rotational torque at the lamp mounting position, and the lamp can be easily mounted and a stable conduction state can be obtained.
[0010]
Further, the width of the engaging recess is formed to be narrower than the width of the lamp pin insertion groove, and the engaging protrusion is formed at two symmetrical positions with respect to the rotation center of the rotor in conformity with the width of the engaging recess, The engagement recess facing the lamp pin insertion groove with respect to the rotation center of the rotor is formed so that the engagement length with the engagement projection is approximately twice that of the other engagement recess. When the insertion groove cannot be used as the engagement recess, the torque required for the rotation operation of the rotor can be made almost constant regardless of the engagement state at every approximately 90 degrees.
3. The rotary socket according to claim 2 , wherein an opening is provided on the front surface, a conductive contact that contacts the lamp pin of the lamp is provided inside the opening, and a lamp pin insertion groove for inserting the lamp pin inside the opening is provided on a side surface. A socket body formed in communication with the opening from
A lamp pin insertion groove that is rotatably provided to cover the opening of the socket body, has a substantially cylindrical wall portion over substantially the entire circumferential side surface, and aligns with the lamp pin insertion groove when the lamp is not mounted. A rotor formed continuously from the wall portion to the front surface to a central portion at least exceeding the rotation center of the rotor,
In the rotary socket in which the lamp pin is rotated approximately 90 degrees together with the rotor while the lamp pin is inserted into the lamp pin insertion groove, and the lamp pin is brought into contact with the conductive contact,
The rotor wall is provided with notch-like engaging recesses at the remaining three locations including the lamp pin insertion groove at intervals of approximately 90 degrees, and the engagement recesses are formed in the socket body by the rotation of the rotor. And an engaging projection that fits into the lamp pin insertion groove,
And, the separation torque from the engagement state between the engagement recess and the engagement projection is set so that the torque at the position where the lamp pin is inserted or removed is equal to or greater than the torque at the lamp mounting position.
Furthermore, the width of the engaging recess is formed to be narrower than the width of the lamp pin insertion groove, and the engaging protrusion is adapted to the width of the engaging recess so as to be symmetrical with respect to the rotation center of the rotor and between them. The engagement recess formed at one of the three locations and facing the lamp pin insertion groove with respect to the rotation center of the rotor has an engagement length with the engagement projection substantially twice that of the other engagement recess. It is formed so that it is.
[0011]
According to the rotary socket of claim 2 , in addition to the same effect as in claim 1, the width of the engagement recess is formed narrower than the width of the lamp pin insertion groove, and the engagement protrusion is the engagement recess. The engagement recesses that are formed at three positions symmetrical to the rotation center of the rotor and one of them in relation to the rotation center of the rotor and facing the lamp pin insertion groove with respect to the rotation center of the rotor are The amount of change in rotational torque at the lamp attachment / detachment position when the lamp pin insertion groove cannot be used as the engagement recess because the engagement length with the mating projection is approximately twice that of the other engagement recess. Therefore, a clearer operational feeling can be obtained, and the position can be easily confirmed.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. That is, this rotary socket has a socket body 1 and a rotor 2.

It is formed in communication with the opening 3. Further, the socket body 1 is provided with an engaging convex portion 13 that fits into the engaging concave portion 6 of the rotor 2.
[0013]
In the embodiment, the socket body 1 is formed of a thermoplastic synthetic resin, and includes an instrument body attachment portion 7 and a bottomed tubular portion 8 attached to the appliance body attachment portion 7, and an end portion of the tubular portion 8. And the lamp insertion groove 5 is formed in the tubular portion 8. A connecting cylinder portion 9 with a split 23 is provided at the center of the bottom of the cylindrical portion 8, and an outward collar-like claw portion 10 is formed on the outer peripheral edge of the tip. As shown in FIG. 3, the intermediate portion of the conductive contact 4 is brought into contact with the peripheral surface in the direction perpendicular to the direction connecting the lamp pin insertion groove 5 and the connecting tube portion 9 by sandwiching the split 23 of the connecting tube portion 9. The both ends of the conductive contact 4 are positioned by positioning portions 12 such as rib-shaped protrusions provided at the bottom of the cylindrical portion 8. Further, they are slidably contacted with the inner peripheral surface of the rotor 2 on the opposite side with respect to the lamp pin insertion groove 5 and the cylindrical portion 9 at a position away from the radial conductive contact 4 centered on the cylindrical portion 9 by a predetermined distance. For example, arc plate-like projecting portions 14a to 14c serving as ribs are provided, and the engaging convex portions 13 are provided on the outer surfaces serving as the sliding contact surfaces of the projecting portions 14a and 14b. In other words, the engagement protrusions 13 are formed at two positions symmetrical with respect to the rotation center of the rotor 2 so as to be adapted to the width of the engagement recess 6 other than the lamp pin insertion groove 11. The conductive contact 4 has a recess 4a for positioning the lamp pin P at a position in contact with the cylindrical portion 9 at the intermediate portion. Reference numeral 4b denotes a terminal portion of the conductive contact 4, which fast connects the electric wires. Reference numeral 22 denotes a male screw for a waterproof ring.
[0014]
The rotor 2 is rotatably provided so as to cover the opening 3 of the socket body 1 and has a substantially cylindrical wall portion 19 over substantially the entire circumferential side surface. The rotor 2 is provided in the lamp pin insertion groove 5 when the lamp is not mounted. The lamp pin insertion groove 11 to be aligned is formed continuously from the wall portion 19 to the front surface 2a to at least the central portion beyond the rotation center of the rotor 2. Engagement recesses 6, for example, notch-like engagement recesses 6, are provided on the wall 19 of the rotor 2 at the remaining three locations including the lamp pin insertion grooves 11 at intervals of approximately 90 degrees. The rotor 2 according to the embodiment is formed of a thermoplastic synthetic resin, covers the conductive contact 4, has a cylindrical portion 16 that fits into the cylindrical portion 9 at the center of the front surface 2a, and has an inner peripheral edge at the end of the cylindrical portion 16. A retaining portion 17 that engages with the claw portion 10 is formed on the rotor body 2, and the rotor 2 is rotatably attached to the socket body 1 using resin elasticity. With the rotor 2 attached, the outer peripheral surfaces of the projecting portions 14a to 14c abut against the inner peripheral surface of the wall portion 19 of the rotor 2, and the wall portion 19 is elastically deformed outward by the engaging convex portion 13 to rotate. The engagement projection 13 is elastically engaged with the engagement recess 6 at a predetermined rotational position of the child 2.
[0015]
In the rotary socket of this embodiment, the lamp pin P is rotated approximately 90 degrees together with the rotor 2 in a state where the lamp pin P is inserted into the lamp pin insertion groove 11, and the lamp pin P is brought into contact with the conductive contact 4. At this time, the detachment torque from the engagement state of the engagement recess 6 and the lamp pin insertion groove 11 and the engagement protrusion 13 is equal to or greater than the torque at the position where the lamp pin P is inserted or removed. It is trying to become.
[0016]
According to this embodiment, when the rotor 2 is turned to align the lamp pin insertion groove 11 with the lamp pin insertion groove 5 of the socket body 1, the lamp pin P can be put into and out of the lamp pin insertion groove 11 of the rotor 2. . After the lamp pin P is moved to the rotation mounting position in the lamp pin insertion groove 11, when the lamp 21 is turned, the rotor 2 also rotates integrally. At this time, since the two lamp pins P protrude into the socket body 1 from the lamp pin insertion groove 11 of the rotor 2, they abut against the contact surface of the conductive contact 4 and elastically deform it, and at the same time, the engaging projections 13 The lamp pin P enters the engagement recess 4a of the conductive contact 4 and the engagement projection 13 engages with the rotor 2 at a position rotated approximately 90 degrees while elastically pressing the wall 19 of the rotor 2 as well. The joint recess 6 is locked while being expanded. When the engaging convex portion 13 fits into the engaging concave portion 6 and the lamp pin insertion groove 11, the engagement convex portion 13 and the engaging concave portion 6 of the rotor 2 or the lamp pin insertion groove 11 are original from the elastic deformation state of the wall portion 19. When returning to the position, a clicking sound is generated, and the lamp pin P becomes conductive. When the lamp pin P is further rotated in either direction from this engaged state, the disengagement torque necessary for rotating the lamp 21 is the torque at which the lamp pin P disengages from the engagement recess 4a of the conductive contact 4. 2 is added to the detachment torque from the engagement state between the socket body 1 and the socket main body 1, and thus becomes larger than the mounting torque of the lamp pin P. Therefore, it is easy to attach the lamp 21 and it is possible to easily confirm a stable conduction state by an operation feeling and a click sound.
[0017]
In this case, by changing the shape of the engagement recess 6 of the rotor 2 from the conventional longitudinal groove, the thickness of the cylindrical wall portion 19 can be reduced, and the engagement protrusion 13 of the socket body 1 can be reduced. Since the elastic deformation equivalent to that of the protrusions 14a and 14b is possible, the amount of deflection when the engagement recess 6 and the engagement protrusion 13 are fitted can be increased, so that a clear click feeling and click sound can be produced. Can now.
[0018]
In addition, since the attachment / detachment position of the lamp 21 is provided every 90 degrees, it is easier to visually confirm the engagement position as compared to the conventional 30 degrees or 45 degrees.
Further, in the attaching / detaching operation of the lamp 21, the detaching torque for rotating the lamp 21 from the lamp mounting state is the torque required for the rotating operation of the engaging convex portion 13 of the socket body 1 and the engaging concave portion 6 of the rotor 2, and the lamp pin. By utilizing the separation torque of P and the conductive contact 4 from the engaging portion 4a, the rotational torque at the lamp mounting position can be exceeded, and the lamp 21 can be easily mounted and a stable conduction state can be obtained.
[0019]
A second embodiment of the present invention is shown in FIG. That is, in the first embodiment, among the engaging recesses 6 and the lamp pin insertion grooves 11 arranged at four positions, the widths other than the lamp pin insertion grooves 11 are formed substantially equal to the width of the lamp pin insertion grooves 11.
According to this embodiment, the torque obtained by removing the torque necessary for rotating from the engaging portion 4a of the conductive contact 4 out of the rotational torque necessary for the rotation operation of the rotor 2 is approximately 90 degrees. Even if it is rotated from the engaged state, it can be made substantially the same.
[0020]
Others are the same as in the first embodiment.
A third embodiment of the present invention is shown in FIGS. In other words, in the first embodiment, among the engaging recesses 6 and the lamp pin insertion grooves 11 of the rotor 2 arranged at four locations, the widths of those other than the lamp pin insertion grooves 11 are narrower than the width of the lamp pin insertion grooves 11. The engagement convex portion 13 of the socket body 1 is formed so as to match the width of the engagement concave portion 6 other than the lamp pin insertion groove 11 of the rotor 2, and the rotation center of the rotor 2 is related to the same as in the first embodiment. Two engagement recesses 6 (6a) that are formed at two symmetrical positions and that face the lamp pin insertion groove 11 with respect to the rotation center of the rotor 2 have an engagement length with the engagement protrusion 13 of the other engagement. It is formed so as to be approximately twice as large as the recess 6. In the embodiment, the hanging piece 19a is integrally hung from the edge of the wall portion 19, and the engaging recess 6a is formed in a notch shape extending over the hanging piece 19a and the wall portion 19 to ensure a predetermined length. Yes.
[0021]
According to this embodiment, at the time of the turning operation from the lamp insertion position to the lamp mounting position (rotated 90 degrees), the two engaging recesses 6 of the rotor 2 and the two engaging protrusions of the socket body 1 are arranged. When the portion 13 is disengaged from the fitting state and is engaged from there to the lamp mounting position (90-degree rotation position), one place of the engagement recess 6a facing the lamp pin insertion groove 11 of the rotor 2; Engagement with either one of the projections 13 of the socket body 1 is achieved. Therefore, when the lamp pin insertion groove 11 cannot be used as the engagement recess 6, the torque required for the rotation operation of the rotor 2 can be made substantially constant from any engagement state at every approximately 90 degrees.
[0022]
Others are the same as those in the first embodiment.
A fourth embodiment of the present invention is shown in FIGS. That is, in the third embodiment, the engagement protrusion 13 of the socket body 1 is symmetric with respect to the rotation center of the rotor 2 so as to match the width of the engagement recess 6 other than the lamp pin insertion groove 11 of the rotor 2. It is formed at three positions, one between them. In other words, in addition to the engaging convex portions 13 of the protruding portions 14a and 14b, the engaging convex portions 13 are also formed on the outer surface of the protruding portion 14c.
[0023]
According to this embodiment, when the lamp pin insertion groove cannot be used as the engaging recess, the amount of change in the rotational torque at the lamp attaching / detaching position can be increased, so that a clearer operational feeling can be obtained and the position can be easily confirmed. .
Others are the same as in the third embodiment.
[0024]
【The invention's effect】
According to the rotary socket of the first aspect, the thickness of the cylindrical wall portion can be reduced by changing the shape of the engagement concave portion of the rotor from the conventional vertical groove, and the engagement of the socket body can be reduced. Since elastic deformation equivalent to the joint convex portion can be made, the amount of deflection when the engaging concave portion and the engaging convex portion are fitted can be increased, so that a clear click feeling and click sound can be produced. . Further, by providing the lamp attachment / detachment position every 90 degrees, it becomes easier to visually confirm the locking position as compared with every 30 degrees or 45 degrees as in the prior art.
[0025]
Further, in the lamp attaching / detaching operation, the detachment torque for rotating the lamp from the lamp mounting state is the torque required for the rotating operation of the engaging convex part of the socket body and the engaging concave part of the rotor, and the relationship between the lamp pin and the conductive contact. By using the separation torque from the joint, it can be made to be equal to or higher than the rotational torque at the lamp mounting position, and the lamp can be easily mounted and a stable conduction state can be obtained.
[0026]
Furthermore, when the lamp pin insertion groove cannot be used as the engagement recess, the torque required for the rotation operation of the rotor can be made almost constant regardless of the engagement state at every approximately 90 degrees.
[0027]
According to the rotary socket of the second aspect , in addition to the same effect as in the first aspect, when the lamp pin insertion groove cannot be used as the engaging recess, the amount of change in the rotational torque at the lamp attaching / detaching position can be increased. A clear operational feeling can be obtained and the position can be easily confirmed.
