Description

この発明は、例えば直管形蛍光灯用照明器具灯などに適用されるランプソケットに関するものである。   The present invention relates to a lamp socket applied to, for example, a lighting fixture for a straight tube fluorescent lamp.

従来例のランプソケットとして、ソケット本体の周側からランプピンをピン孔に挿入し導電端子に接続可能とするために、ピン孔は一端がソケット本体周側に向かって開口した長孔状に設けられたものがある（例えば、特許文献１，２参照）。また、このランプソケットは防水性を確保するために、パッキンを収容したカバー筒体（防水リング）がソケット本体のねじ筒に螺合される。
特開２０００−３１５５８号公報 特開２０００−３１５５７号公報 As a conventional lamp socket, in order to allow a lamp pin to be inserted into the pin hole from the circumferential side of the socket body and to be connected to the conductive terminal, the pin hole is provided in a long hole shape with one end opened toward the socket body circumferential side. (For example, see Patent Documents 1 and 2). In addition, in order to ensure the waterproofness of the lamp socket, a cover cylinder (waterproof ring) containing a packing is screwed into a screw cylinder of the socket body.
JP 2000-31558 A JP 2000-31557 A

従来例のランプソケットは、上記のように防水リングを有する防水ソケットとして用いられている。通常の使用状態では、ランプは防水リングによって支えられているが、ランプ交換作業中は防水リングが取り外され、点灯検査などのために、ランプが導電端子によってのみ保持された状態で放置されることが多い。このとき、振動、衝撃等によりランプ落下の恐れがあるため、防水リングが無い状態でも、ランプが落下しない性能が、安全面からも作業性からも必要となっている。   The lamp socket of the conventional example is used as a waterproof socket having a waterproof ring as described above. Under normal conditions of use, the lamp is supported by a waterproof ring, but the lamp is removed during lamp replacement work, and the lamp is only held by a conductive terminal for lighting inspection. There are many. At this time, since there is a risk of the lamp falling due to vibration, impact, etc., the performance that the lamp does not fall is required from the viewpoint of safety and workability even without the waterproof ring.

したがって、この発明の目的は、ランプが導電端子によってのみ保持されるような状態でも、ランプの落下を防止することができるランプソケットを提供することである。   Accordingly, an object of the present invention is to provide a lamp socket capable of preventing the lamp from falling even when the lamp is held only by the conductive terminal.

上記課題を解決するためにこの発明の請求項１記載のランプソケットは、ソケット本体の周囲から中心に向かう２本のランプピン挿入開口部を有し、ランプピンは、前記ランプピン挿入開口部に沿って挿入され、前記ランプピン挿入開口部のそれぞれの端部にて導電端子に接触した状態で保持されるランプソケットにおいて、前記ランプピン挿入開口部の入口近傍にランプピン仮保持部を設けてランプピンを保持可能とし、かつ前記ランプピン仮保持部は、対向するランプピンの内側に接触する部位がランプの中心軸側に弾性変形可能とした。   In order to solve the above-mentioned problem, the lamp socket according to claim 1 of the present invention has two lamp pin insertion openings from the periphery of the socket body toward the center, and the lamp pins are inserted along the lamp pin insertion opening. In the lamp socket that is held in contact with the conductive terminal at each end of the lamp pin insertion opening, a lamp pin temporary holding portion is provided in the vicinity of the entrance of the lamp pin insertion opening so that the lamp pin can be held. In addition, the lamp pin temporary holding portion can be elastically deformed toward the center axis side of the lamp at a portion contacting the inside of the opposite lamp pin.

請求項２記載のランプソケットは、請求項１記載のランプソケットにおいて、前記ランプピン仮保持部が位置する２本のランプピン挿入開口部の間にスリットを設けた。   The lamp socket according to claim 2 is the lamp socket according to claim 1, wherein a slit is provided between the two lamp pin insertion openings where the lamp pin temporary holding portion is located.

請求項３記載のランプソケットは、請求項２記載のランプソケットにおいて、前記ランプピン仮保持部は、ランプピン挿入開口部の内側と外側に対向するように形成された一対の凸部からなり、ランプ軸方向の投影面上で前記一対の凸部の中間点はランプ挿入開口部の中心線より外側にある。   The lamp socket according to claim 3 is the lamp socket according to claim 2, wherein the lamp pin temporary holding portion includes a pair of convex portions formed so as to face the inner side and the outer side of the lamp pin insertion opening portion. On the projection plane in the direction, the midpoint of the pair of convex portions is outside the center line of the lamp insertion opening.

請求項４記載のランプソケットは、請求項２記載のランプソケットにおいて、前記ランプピン仮保持部は、ランプピン挿入開口部の内側と外側に対向するように形成された一対の凸部からなり、外側の凸部を内側の凸部よりソケット本体の中心方向に長くした。   The lamp socket according to claim 4 is the lamp socket according to claim 2, wherein the lamp pin temporary holding portion includes a pair of convex portions formed so as to face the inside and the outside of the lamp pin insertion opening, The convex part is longer than the inner convex part in the center direction of the socket body.

請求項５記載のランプソケットは、請求項２記載のランプソケットにおいて、前記スリットにより分けられた２つのランプピン挿入開口部の内壁の間に、内壁の過変形防止突起部が配置されている。   According to a fifth aspect of the present invention, in the lamp socket according to the second aspect, an over-deformation preventing projection on the inner wall is disposed between the inner walls of the two lamp pin insertion openings divided by the slit.

この発明の請求項１記載のランプソケットによれば、ランプピン挿入開口部の入口近傍にランプピン仮保持部を設けてランプピンを保持可能とし、かつランプピン仮保持部は、対向するランプピンの内側に接触する部位がランプの中心軸側に弾性変形可能としたので、ランプがソケット内部の導電端子から外れたときでも、ランプピン仮保持部によりランプピンが保持されることでランプ落下の恐れがなく安全性が向上する。また、ランプピン仮保持部が弾性変形することで、ランプの繰り返し着脱によるランプピン仮保持部の劣化が小さくなる。また、ランプピン仮保持部が内側に弾性変形するため、ソケットが大きくなることはない。   According to the lamp socket of the first aspect of the present invention, the lamp pin temporary holding portion is provided in the vicinity of the entrance of the lamp pin insertion opening so as to be able to hold the lamp pin, and the lamp pin temporary holding portion is in contact with the inside of the facing lamp pin. Since the part can be elastically deformed toward the center axis of the lamp, even if the lamp is detached from the conductive terminal inside the socket, the lamp pin is held by the temporary holding pin of the lamp, so there is no risk of the lamp falling and safety is improved. To do. In addition, since the lamp pin temporary holding portion is elastically deformed, deterioration of the lamp pin temporary holding portion due to repeated attachment and detachment of the lamp is reduced. Further, since the lamp pin temporary holding portion is elastically deformed inward, the socket does not become large.

請求項２では、ランプピン仮保持部が位置する２本のランプピン挿入開口部の間にスリットを設けたので、ランプピン仮保持部の対向するランプピンの内側に接触する部位がランプの中心軸側に弾性変形する構成をコストアップなく容易に実現できる。   According to the second aspect of the present invention, since the slit is provided between the two lamp pin insertion openings where the lamp pin temporary holding portion is located, the portion of the lamp pin temporary holding portion that contacts the inside of the facing lamp pin is elastic toward the center axis side of the lamp. A deformable configuration can be easily realized without increasing the cost.

請求項３では、ランプピン仮保持部は、ランプピン挿入開口部の内側と外側に対向するように形成された一対の凸部からなり、ランプ軸方向の投影面上で一対の凸部の中間点はランプ挿入開口部の中心線より外側にあるので、ランプピン挿入開口部とランプピン仮保持部の位置関係により、ランプピン仮保持部の内側の凸部がたわみやすく、外側の凸部がたわむ場合と比較してソケットが小さくなる。   According to a third aspect of the present invention, the lamp pin temporary holding portion includes a pair of convex portions formed so as to face the inner side and the outer side of the lamp pin insertion opening, and an intermediate point between the pair of convex portions on the projection surface in the lamp axis direction is Because it is outside the center line of the lamp insertion opening, the convex part on the inner side of the lamp pin temporary holding part tends to bend due to the positional relationship between the lamp pin insertion opening and the temporary holding part of the lamp pin, compared with the case where the outer convex part is bent. The socket becomes smaller.

請求項４では、ランプピン仮保持部は、ランプピン挿入開口部の内側と外側に対向するように形成された一対の凸部からなり、外側の凸部を内側の凸部よりソケット本体の中心方向に長くしたので、ランプピン仮保持部の内側の凸部は、ランプ挿入時のみ機能する。ランプ仮保持状態では、外側の凸部にランプの荷重がかかる。よって、弾性変形により可動する内側の凸部に、荷重がかかったままにはならないので安全である。   According to a fourth aspect of the present invention, the lamp pin temporary holding portion is composed of a pair of convex portions formed so as to face the inner side and the outer side of the lamp pin insertion opening portion, and the outer convex portion is moved from the inner convex portion toward the center of the socket body. Since it is made longer, the convex part inside the lamp pin temporary holding part functions only when the lamp is inserted. In the lamp temporary holding state, a load of the lamp is applied to the outer convex portion. Therefore, it is safe because a load is not left on the inner convex portion that is movable by elastic deformation.

請求項５では、スリットにより分けられた２つのランプピン挿入開口部の内壁の間に、内壁の過変形防止突起部が配置されているので、外部からの無理な力により、ランプピン仮保持部の破損を防止することができる。   According to the fifth aspect of the present invention, since the over-deformation preventing protrusion of the inner wall is disposed between the inner walls of the two lamp pin insertion openings divided by the slit, the lamp pin temporary holding portion is damaged by an excessive force from the outside. Can be prevented.

この発明の第１の実施の形態の図１〜図６に基づいて説明する。図１はこの発明の第１の実施形態のランプソケットの要部分解斜視図、図２はその組み立てた状態の正面図、図３はこの発明の第１の実施形態のランプソケットの全体斜視図、図４はその分解斜視図である。   A first embodiment of the present invention will be described with reference to FIGS. 1 is an exploded perspective view of a main part of a lamp socket according to a first embodiment of the present invention, FIG. 2 is a front view of the assembled lamp socket, and FIG. 3 is an overall perspective view of the lamp socket according to the first embodiment of the present invention. FIG. 4 is an exploded perspective view thereof.

図１〜図４において、１はソケット本体、２はソケット本体のカバー、３は導電端子、４は防水リングパッキン、５は金属リング、６は樹脂リング（防水リング）、７はリード線用パッキンである。   1-4, 1 is a socket body, 2 is a cover of the socket body, 3 is a conductive terminal, 4 is a waterproof ring packing, 5 is a metal ring, 6 is a resin ring (waterproof ring), and 7 is a lead wire packing. It is.

図１および図２に示すように、ソケット本体１は、周囲にねじを設けたねじ筒部１０を有し、その内部に導電端子３を覆うカバー２を装着している。また、ソケット本体１の周囲から中心に向かう２本のランプピン挿入開口部１１を有する。各ランプピン挿入開口部１１は導電端子３が臨むようにカバー２に形成されるとともに、その延長方向のねじ筒部１０の位置を切欠くように形成された開口部分１１ａを有する。ランプピンは、ランプピン挿入開口部１１に沿って矢印のように挿入され、ランプピン挿入開口部１１のそれぞれの端部にて導電端子３に接触した状態で保持される。また、ソケット本体１、カバー２は熱可塑性樹脂等で形成される。ソケット本体１には取付溝１４、水抜き穴（図示せず）が形成されている。カバー２は冷間かしめ１３によりソケット本体１に固定される。   As shown in FIGS. 1 and 2, the socket main body 1 has a screw cylinder portion 10 provided with a screw around it, and a cover 2 that covers the conductive terminal 3 is mounted therein. Further, the lamp body has two lamp pin insertion openings 11 from the periphery of the socket body 1 toward the center. Each lamp pin insertion opening portion 11 is formed in the cover 2 so that the conductive terminal 3 faces, and has an opening portion 11a formed so as to cut out the position of the screw tube portion 10 in the extending direction. The lamp pin is inserted along the lamp pin insertion opening 11 as indicated by an arrow, and is held in contact with the conductive terminal 3 at each end of the lamp pin insertion opening 11. The socket body 1 and the cover 2 are made of a thermoplastic resin or the like. The socket body 1 is formed with a mounting groove 14 and a drain hole (not shown). The cover 2 is fixed to the socket body 1 by cold caulking 13.

上記ソケット本体１の構成において、ランプピン挿入開口部１１の入口近傍にランプピンを保持可能なランプピン仮保持部１６を設けている。このランプピン仮保持部１６は、対向するランプピン２０の内側に接触する部位がランプの中心軸側に弾性変形可能とした構成である。この場合、ランプピン仮保持部１６は、ランプピン挿入開口部１１の内側と外側に対向するように形成された一対の凸部１６ａ，１６ｂからなる。一対の凸部１６ａ，１６ｂの間隔Ｌはランプピン径より狭い。また、ランプピン仮保持部１６が位置する２本のランプピン挿入開口部１１の間にスリット１７を設けることで、内側の凸部１６ａがランプの中心軸側に弾性変形する。   In the configuration of the socket body 1, a lamp pin temporary holding portion 16 capable of holding the lamp pin is provided in the vicinity of the entrance of the lamp pin insertion opening 11. The lamp pin temporary holding portion 16 has a configuration in which a portion contacting the inside of the facing lamp pin 20 can be elastically deformed toward the center axis side of the lamp. In this case, the lamp pin temporary holding portion 16 includes a pair of convex portions 16 a and 16 b formed so as to face the inside and the outside of the lamp pin insertion opening 11. The distance L between the pair of convex portions 16a and 16b is narrower than the lamp pin diameter. Further, by providing the slit 17 between the two lamp pin insertion openings 11 where the lamp pin temporary holding portion 16 is located, the inner convex portion 16a is elastically deformed toward the center axis side of the lamp.

図５はランプピン仮保持状態を示す。図５に示すように、開口部分１１ａからランプピン挿入開口部１１に沿って挿入されたランプピン２０はランプピン仮保持部１６により保持される。この際、ランプピン仮保持部１６がランプピン２０と接触することで、スリット１７により分けられた２つのランプピン挿入開口部１１の内壁１８が弾性変形する。また、外部からの無理な力により内壁１８が過多に変形するのを防止するために、過変形防止突起部２２が配置されている。この過変形防止突起部２２はソケット本体１に突設され、スリット１７の対向面に形成された凹所２３に嵌合される。   FIG. 5 shows the lamp pin temporary holding state. As shown in FIG. 5, the lamp pin 20 inserted along the lamp pin insertion opening portion 11 from the opening portion 11 a is held by the lamp pin temporary holding portion 16. At this time, when the lamp pin temporary holding portion 16 comes into contact with the lamp pin 20, the inner walls 18 of the two lamp pin insertion openings 11 separated by the slit 17 are elastically deformed. Further, in order to prevent the inner wall 18 from being excessively deformed by an excessive force from the outside, the over-deformation preventing protrusion 22 is disposed. This over-deformation preventing protrusion 22 protrudes from the socket body 1 and is fitted into a recess 23 formed on the opposing surface of the slit 17.

図６（ａ）はランプピン接続状態、（ｂ）はランプピン仮保持状態を示す。なお、同図ではランプ長さを縮小表示している。図６に示すように、ランプ２１が導電板３による接続位置からできる限り離れた位置で仮保持されるため、ランプ２１が正規の接続位置にないことが視覚的にわかりやすい。   FIG. 6A shows a lamp pin connection state, and FIG. 6B shows a lamp pin temporary holding state. In the figure, the lamp length is reduced and displayed. As shown in FIG. 6, since the lamp 21 is temporarily held at a position as far as possible from the connection position by the conductive plate 3, it is visually easy to understand that the lamp 21 is not in the normal connection position.

また、図３および図４に示すように、防水リングパッキン４は、ねじ筒部１０とカバー２との間に挿入される。樹脂リング６は、ソケット本体１のねじ筒部１０に螺合し、金属リング５が当接するように端縁部が形成されている。図３に示す組み立て状態では、ランプピンの接続後において、防水リングパッキン４の一端側をソケット本体のねじ筒部１０とカバー２の間に挿入し、他端側に金属リング５を配置して、樹脂リング６を被せてねじ筒部１０に螺合して締め込む。これにより、防水リングパッキン４が圧縮されて防水性能が確保される。金属リング５は樹脂リング６と防水リングパッキン４の間に配置され、樹脂リング６の回転時の摩擦を低減させるためのものである。   As shown in FIGS. 3 and 4, the waterproof ring packing 4 is inserted between the screw tube portion 10 and the cover 2. The resin ring 6 is screwed into the threaded cylinder portion 10 of the socket body 1 and has an edge portion so that the metal ring 5 contacts. In the assembled state shown in FIG. 3, after the lamp pin is connected, one end side of the waterproof ring packing 4 is inserted between the screw tube portion 10 of the socket body and the cover 2, and the metal ring 5 is disposed on the other end side. The resin ring 6 is put on and screwed into the screw cylinder portion 10 and tightened. Thereby, the waterproof ring packing 4 is compressed and waterproof performance is ensured. The metal ring 5 is disposed between the resin ring 6 and the waterproof ring packing 4 to reduce friction when the resin ring 6 rotates.

本実施形態によれば、ランプがソケット内部の導電端子３から外れたときでも、ランプピン仮保持部１６によりランプピンが保持されることでランプ落下の恐れがなく安全性が向上する。特に、ランプ交換作業中は、樹脂リング６が取り外され、ランプは導電端子３のみによって保持されており、また、点灯検査などのため、この状態のまま放置されることが多い。このとき振動や衝撃により、ランプが導電端子３から外れても落下を防止することができる。   According to the present embodiment, even when the lamp is detached from the conductive terminal 3 inside the socket, the lamp pin is held by the lamp pin temporary holding portion 16 so that there is no fear of the lamp falling and the safety is improved. In particular, during the lamp replacement operation, the resin ring 6 is removed, and the lamp is held only by the conductive terminal 3 and is often left in this state for lighting inspection and the like. At this time, even if the lamp is detached from the conductive terminal 3 due to vibration or impact, the fall can be prevented.

また、ランプピン仮保持部１６がスリット１７により弾性変形することで、ランプの繰り返し着脱によるランプピン仮保持部１６の劣化が小さくなる。また、ランプピン仮保持部１６が内側に弾性変形するため、ソケットが大きくなることはない。   In addition, since the lamp pin temporary holding portion 16 is elastically deformed by the slit 17, the deterioration of the lamp pin temporary holding portion 16 due to repeated attachment and detachment of the lamp is reduced. Moreover, since the lamp pin temporary holding portion 16 is elastically deformed inward, the socket does not become large.

なお、ランプピン仮保持部１６は、対向するランプピンの内側に接触する部位がランプの中心軸側に弾性変形可能としたものであれば、スリットはなくてもよい。例えば、図７に示すように、ランプピン挿入開口部１１のランプの中心軸側の側面に凹部２５を設け、この凹部２５と一体にランプピン仮保持部１６の内側の凸部１６ａを形成してもよい。この場合、ランプピン仮保持部１６がランプピン２０との接触により、内側の凸部１６ａが凹部２５内へ押し込まれるようにばね性を持たせている。   Note that the lamp pin temporary holding portion 16 may not have a slit as long as the portion that contacts the inside of the opposite lamp pin can be elastically deformed toward the center axis of the lamp. For example, as shown in FIG. 7, a concave portion 25 is provided on the side surface of the lamp pin insertion opening 11 on the center axis side of the lamp, and the convex portion 16 a inside the lamp pin temporary holding portion 16 is formed integrally with the concave portion 25. Good. In this case, the lamp pin temporary holding portion 16 has a spring property so that the inner convex portion 16 a is pushed into the concave portion 25 by contact with the lamp pin 20.

また、図８は比較例であり、ランプピン２０の先端を仮保持する構造である。この場合、ランプピン仮保持部２６はソケット本体１の内底面に突設している。２７はランプ２１の保持高さである。本実施形態のようにランプピン径方向にランプピン仮保持部２６を設けたものと比較すると仮保持性能は低下する。   FIG. 8 shows a comparative example in which the tip of the lamp pin 20 is temporarily held. In this case, the lamp pin temporary holding portion 26 protrudes from the inner bottom surface of the socket body 1. Reference numeral 27 denotes a holding height of the lamp 21. As compared with the present embodiment in which the lamp pin temporary holding portion 26 is provided in the lamp pin radial direction, the temporary holding performance is lowered.

この発明の第２の実施の形態の図９に基づいて説明する。図９はこの発明の第２の実施形態のランプソケットの要部正面図である。   A second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a front view of an essential part of a lamp socket according to a second embodiment of the present invention.

図９に示すように、ランプピン仮保持部１６は、第１の実施形態と同様にランプピン挿入開口部の内側と外側に対向するように形成された一対の凸部１６ａ，１６ｂからなるが、ランプ軸方向の投影面上で一対の凸部１６ａ，１６ｂの中間点はランプ挿入開口部１１の中心線より外側にある。すなわち、ランプ挿入開口部１１の中心線から内側の凸部１６ａまでの距離ａと、外側の凸部１６ｂまでの距離ｂとの関係は、ａ＜ｂとなっている。   As shown in FIG. 9, the lamp pin temporary holding portion 16 includes a pair of convex portions 16a and 16b formed so as to face the inner side and the outer side of the lamp pin insertion opening as in the first embodiment. The midpoint between the pair of convex portions 16 a and 16 b is outside the center line of the lamp insertion opening 11 on the axial projection surface. That is, the relationship between the distance a from the center line of the lamp insertion opening 11 to the inner convex portion 16a and the distance b to the outer convex portion 16b is a <b.

本実施形態によれば、ランプピン挿入開口部１１とランプピン仮保持部１６の位置関係により、内側の凸部１６ａのほうがたわみ易くなる。そのため、ソケットが外向きに広がりにくいので小さくなる。その他の構成効果は、第１の実施の形態と同様である。   According to the present embodiment, due to the positional relationship between the lamp pin insertion opening 11 and the lamp pin temporary holding portion 16, the inner convex portion 16a is more easily bent. Therefore, the socket is small because it is difficult to spread outward. Other structural effects are the same as those of the first embodiment.

この発明の第３の実施の形態の図１０および図１１に基づいて説明する。図１０はこの発明の第３の実施形態のランプソケットの要部正面図、図１１はこの発明の第３の実施形態のランプピン仮保持状態の説明図である。   A third embodiment of the present invention will be described with reference to FIGS. FIG. 10 is a front view of an essential part of a lamp socket according to a third embodiment of the present invention, and FIG. 11 is an explanatory view of a lamp pin temporary holding state according to a third embodiment of the present invention.

図１０に示すように、ランプピン仮保持部１６は、第１の実施形態と同様にランプピン挿入開口部１１の内側と外側に対向するように形成された一対の凸部１６ａ，１６ｂからなるが、外側の凸部１６ｂを内側の凸部１６ａよりソケット本体１の中心方向に長くした。すなわち、内側の凸部１６ａの長さｃと、外側の凸部１６ｂの長さｄとの関係は、ｃ＜ｄとなっている。   As shown in FIG. 10, the lamp pin temporary holding portion 16 includes a pair of convex portions 16 a and 16 b formed so as to face the inner side and the outer side of the lamp pin insertion opening 11 as in the first embodiment. The outer protrusion 16b is made longer in the center direction of the socket body 1 than the inner protrusion 16a. That is, the relationship between the length c of the inner convex portion 16a and the length d of the outer convex portion 16b is c <d.

本実施形態によれば、ランプピン仮保持部１６の内側の凸部１６ａは、ランプ挿入時のみ機能する。ランプ仮保持状態では、図１１に示すように、ランプピン２０が外側の凸部１６ｂに当接し、この凸部１６ｂにランプの荷重がかかる。よって、弾性変形により可動する内側の凸部１６ａに、荷重がかかり続けることはない。また、最大のランプピン保持力は、ｃ＝ｄのときと同じである。その他の構成効果は、第１の実施の形態と同様である。   According to this embodiment, the convex part 16a inside the lamp pin temporary holding part 16 functions only when the lamp is inserted. In the lamp temporary holding state, as shown in FIG. 11, the lamp pin 20 contacts the outer convex portion 16b, and a load of the lamp is applied to the convex portion 16b. Therefore, a load is not continuously applied to the inner convex portion 16a that is movable by elastic deformation. The maximum lamp pin holding force is the same as when c = d.
