上述の特許文献1に示したランプソケットでは、ランプピンの回転軌道に対して垂直方向からの導電板の挟持力によってランプピンと導電板とが接触しているので、突出部と係止ばねの係止が不完全な状態でも点灯する場合があった。しかしこの状態で使用を継続した場合には、振動等によって突出部と係止ばねとの係合が外れ、ランプが落下する虞れがあった。   In the lamp socket shown in Patent Document 1 described above, the lamp pin and the conductive plate are in contact with each other by the holding force of the conductive plate from the direction perpendicular to the rotation track of the lamp pin. May be lit even incomplete state. However, if the use is continued in this state, the projection and the locking spring are disengaged due to vibration or the like, and the lamp may fall.

また、ランプを着脱する際に加える力を高く設定し、ランプを勢いよく回転させることで不完全な装着状態を回避できるランプソケットも提案されているが、この場合力を加えるための回転作業スペースを広く取る必要があるので、照明器具が大型化してしまうという問題があった。   In addition, a lamp socket that can avoid an incomplete mounting state by setting a high force when attaching and detaching the lamp and rotating the lamp vigorously has been proposed, but in this case the rotating work space for applying the force Therefore, there is a problem that the lighting fixture becomes large.

本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、小型化することができ、且つ突出部を係止ばねに確実に係止させた状態でランプを点灯させることができるランプソケット及びそれを用いた照明器具を提供することにある。   The present invention has been made in view of the above problems, and its object is to make the lamp light in a state where the size can be reduced and the protruding portion is securely locked by the locking spring. An object of the present invention is to provide a lamp socket and a lighting fixture using the same.

請求項1の発明は、ランプピンが底部に突設されるとともに互いに対向する両側面に突出部がそれぞれ形成された片口金ランプの口金部が挿入される収納凹部を前面側に有し、口金部を収納凹部に挿入させる際に突出部を挿通させる挿通溝及び当該挿通溝と連通し口金部を一方向に回転させた際に突出部が進入する係合溝が収納凹部の側壁に形成されたソケット本体と、係合溝内に配置されて突出部と係止する係止ばねと、口金部を一方向に回転させた際にランプピンと電気的に接続される導電板とを備え、挿通溝に挿入された突出部係止ばねから最大付勢力が加えられている不完全状態では、導電板からの付勢力によってランプピンを前面側に押し返すことで、係合溝内への進入方向と反対方向に突出部を移動させ、挿通溝に挿入された突出部が係止ばねに係止された状態では、係止ばねから突出部が受ける付勢力によってランプピンが導電板に押し当てられ、ランプピンと導電板とが安定的に接続した状態になることを特徴とする。 According to a first aspect of the present invention, there is provided a housing recess on the front side into which a base part of a single base lamp in which a lamp pin protrudes from the bottom part and a protrusion part is formed on each side surface facing each other is inserted. An insertion groove through which the protrusion is inserted when the protrusion is inserted into the storage recess and an engagement groove into which the protrusion enters when the base portion is rotated in one direction are formed in the side wall of the storage recess. An insertion groove comprising a socket body, a locking spring disposed in the engagement groove and locked to the protruding portion, and a conductive plate electrically connected to the lamp pin when the base portion is rotated in one direction. opposite the incomplete state of maximum energizing force is applied from the locking spring on the protrusion that is inserted, the lamp pins by the biasing force of the conductive plate by pushing back on the front side, the approach direction into the engaging groove in The protrusion was moved in the direction and inserted into the insertion groove In a state where the protruding portion is locked by the locking spring, the lamp pin is pressed against the conductive plate by the biasing force received by the protruding portion from the locking spring, and the lamp pin and the conductive plate are stably connected. Features.

請求項2の発明は、請求項1記載のランプソケットと、ランプと、当該ランプに電源を供給する電源手段とを備えたことを特徴とする。   The invention of claim 2 is characterized by comprising the lamp socket according to claim 1, a lamp, and power supply means for supplying power to the lamp.

請求項1の発明によれば、突出部と係止ばねとが係止完了状態になってはじめてランプピンと導電板とが安定接続されるので、突出部と係止ばねとの係止が不完全な状態で放置されることがない。従って、突出部を係止ばねに確実に係止させることができるので、ランプの落下を防止することができるという効果がある。また、係止ばねの付勢力が最大となる位置では、ランプピンは導電板から前面側に押し返し力を受けており、この状態で放置した場合、導電板の押し返し力によって突出部が前面側に押し出され、突出部と係止ばねとの係止が外れてしまう。従って、突出部と係止ばねとが不完全な係止状態に極めてなりにくいという効果がある。   According to the first aspect of the present invention, since the lamp pin and the conductive plate are stably connected only after the protruding portion and the locking spring are in the locked state, the locking between the protruding portion and the locking spring is incomplete. Will not be left unattended. Therefore, since the protruding portion can be reliably locked to the locking spring, there is an effect that the lamp can be prevented from falling. In addition, at the position where the urging force of the locking spring is maximized, the lamp pin receives a pushing force from the conductive plate to the front side, and if left in this state, the protrusion is pushed to the front side by the pushing force of the conductive plate. As a result, the locking between the protruding portion and the locking spring is released. Therefore, there is an effect that the protruding portion and the locking spring are hardly in an incompletely locked state.

請求項2の発明によれば、請求項1記載のランプソケットを用いることによって、ランプの落下の虞れがない安全性の高い照明器具を提供することができるという効果がある。また、ランプを着脱する際に加える力を必要以上に大きくしなくてもよく、ランプを着脱するための回転作業スペースを最小限にすることができるので、照明器具を小型化することができるという効果がある。   According to the invention of claim 2, by using the lamp socket of claim 1, there is an effect that it is possible to provide a highly safe lighting apparatus that is free from the possibility of the lamp falling. In addition, it is not necessary to increase the force applied when attaching / detaching the lamp more than necessary, and the rotation work space for attaching / detaching the lamp can be minimized, so that the lighting fixture can be miniaturized. effective.

ここで、ランプAをランプソケットBに装着する際のランプピン3と導電部材9との関係及び突出部2aと係止ばね7との関係について、図1に基づいて説明する。まず、口金部2と収納凹部5aの位置を合わせて口金部2を収納凹部5aの底部に当接するまで挿入すると、突出部2aは挿通溝5c内に挿入されて、図1(a)に示す位置に配置される。この時、各ランプピン3は、対応するランプピン挿入孔5j内にそれぞれ挿入されて、導電部材9と非接触の状態で保持されている。この状態から口金部2を回転させると、図1(b)に示すように突出部2aが係合溝5b内に進入し、突出部2aは係止ばね7の可動ばね片7bに接触する。この時、各ランプピン3は、口金部2の回転動作に従ってランプピン挿入孔5j内をそれぞれ移動し、対応する導電部材9にそれぞれ接触する。さらに、口金部2を回転させると、図1(c)に示すように突出部2aに押されて可動ばね片7bが弾性変形する。この時、各ランプピン3は、対応する導電部材9から前面側に押し返し力を受けている。従って、この状態で放置すると、導電部材9からの押し返し力によってランプピン3が前面側に押し出され、突出部2aが回転方向と逆向きの力を受けるので、突出部2aと係止ばね7との係止が外れてしまう。尚、突出部2aは、この状態において可動ばね片7bから最大の付勢力を受けている。そして、図1(c)の状態からさらに口金部2を回転させると、図1(d)に示すように突出部2aは下向きに弾性付勢された状態で係止片7cと係止し、口金部2が収納凹部5aの底部に押付けられた状態で保持されて、ランプAがランプソケットBに装着される。この時、口金部2が収納凹部5aの底部に押付けられることによって各ランプピン3も下向きに付勢されるので、各ランプピン3がそれぞれ対応する導電部材9に押付けられ、ランプピン3と導電部材9とが安定接続される。ここに、図1(d)に示す突出部2aと係止片7cとの係止状態を係止完了状態という。   Here, the relationship between the lamp pin 3 and the conductive member 9 and the relationship between the protrusion 2a and the locking spring 7 when the lamp A is mounted in the lamp socket B will be described with reference to FIG. First, when the base part 2 and the storage recess 5a are aligned and inserted until the base part 2 comes into contact with the bottom of the storage recess 5a, the protrusion 2a is inserted into the insertion groove 5c, as shown in FIG. Placed in position. At this time, each lamp pin 3 is inserted into the corresponding lamp pin insertion hole 5j, and is held in a non-contact state with the conductive member 9. When the base part 2 is rotated from this state, as shown in FIG. 1B, the projecting part 2 a enters the engaging groove 5 b, and the projecting part 2 a contacts the movable spring piece 7 b of the locking spring 7. At this time, each lamp pin 3 moves in the lamp pin insertion hole 5j according to the rotation operation of the cap portion 2, and contacts the corresponding conductive member 9, respectively. Further, when the base portion 2 is rotated, the movable spring piece 7b is elastically deformed by being pushed by the protruding portion 2a as shown in FIG. 1 (c). At this time, each lamp pin 3 receives a pushing force from the corresponding conductive member 9 to the front side. Accordingly, if left in this state, the lamp pin 3 is pushed to the front side by the pushing back force from the conductive member 9, and the protruding portion 2a receives a force opposite to the rotational direction. The lock is released. In this state, the protruding portion 2a receives the maximum urging force from the movable spring piece 7b. Then, when the base part 2 is further rotated from the state of FIG. 1 (c), as shown in FIG. 1 (d), the protruding part 2a is locked with the locking piece 7c while being elastically biased downward, The base 2 is held while being pressed against the bottom of the housing recess 5 a, and the lamp A is mounted on the lamp socket B. At this time, since the base portion 2 is pressed against the bottom of the housing recess 5a, each lamp pin 3 is also urged downward, so that each lamp pin 3 is pressed against the corresponding conductive member 9, and the lamp pin 3, conductive member 9 and Is connected stably. Here, the locked state between the protruding portion 2a and the locking piece 7c shown in FIG.

逆に、ランプソケットBからランプAを取り外す場合には、まず口金部2を取付方向と反対方向に回転させると、突出部2aと係止片7cとの係止が外れる。この時、各ランプピン3は、導電部材9と不安定な状態で接続している。さらに、口金部2を回転させると、突出部2aが係合溝5bに沿って挿通溝5cまで移動する。この時、ランプピン3と導電部材9との接続が解除される(図1(a)参照)。そして、ランプAを引き抜くと、突出部2aが挿通溝5cに沿って前面側に移動し、ランプAがランプソケットBから取り外される。   On the contrary, when the lamp A is removed from the lamp socket B, first, when the cap portion 2 is rotated in the direction opposite to the mounting direction, the locking between the protruding portion 2a and the locking piece 7c is released. At this time, each lamp pin 3 is connected to the conductive member 9 in an unstable state. Further, when the base part 2 is rotated, the projecting part 2a moves to the insertion groove 5c along the engaging groove 5b. At this time, the connection between the lamp pin 3 and the conductive member 9 is released (see FIG. 1A). When the lamp A is pulled out, the protruding portion 2a moves to the front side along the insertion groove 5c, and the lamp A is removed from the lamp socket B.

このランプソケットBでは、突出部2aと係止片7cとが係止完了状態になってはじめてランプピン3と導電部材9とが安定接続されるので、突出部2aと係止片7cとの係合が不完全な状態で放置されることがない。従って、突出部2aを係止片7cに確実に係止させることができるので、ランプAの落下を防止することができる。また、可動ばね片7bから突出部2aが受ける付勢力が最大となる位置(図1(c)の位置)では、ランプピン3は導電部材9から前面側に押し返し力を受けており、この状態で放置した場合、導電部材9の押し返し力によって突出部2aが前面側に押し出され、突出部2aが回転方向と逆向きの力を受けるので、突出部2aと係止ばね7との係止が外れてしまう。従って、突出部2aと係止ばね7とが不完全な係止状態に極めてなりにくい。   In the lamp socket B, the lamp pin 3 and the conductive member 9 are stably connected only after the protruding portion 2a and the locking piece 7c are in the locked state. Will not be left incomplete. Therefore, since the protrusion 2a can be reliably locked to the locking piece 7c, the lamp A can be prevented from falling. Further, at the position where the urging force received by the projecting portion 2a from the movable spring piece 7b is maximized (the position shown in FIG. 1 (c)), the lamp pin 3 receives the pushing back force from the conductive member 9 to the front side. If left untreated, the projecting portion 2a is pushed to the front side by the pushing back force of the conductive member 9, and the projecting portion 2a receives a force in the direction opposite to the rotational direction, so that the locking between the projecting portion 2a and the locking spring 7 is released. End up. Therefore, the protruding portion 2a and the locking spring 7 are unlikely to be in an incompletely locked state.
