Description

本発明は蛍光管用ソケットに関し、特に液晶テレビ等の液晶表示装置のバックライト用蛍光管のソケットに適する。   The present invention relates to a fluorescent tube socket, and is particularly suitable for a backlight fluorescent tube socket of a liquid crystal display device such as a liquid crystal television.

液晶表示装置等に用いられるバックライトとして冷陰極蛍光管等の蛍光管が周知である。
この種の蛍光管はリジット基板に接続するソケットに装着されるが、点灯と消灯により蛍光管の両端の電極間長さ、ソケット、ソケットを取り付けたシャーシ及び基板のそれぞれの間に相対的な熱伸縮差が生じる。
これらの熱伸縮差を吸収する機構を設けてやらないと蛍光管の電極とソケットのコンタクトの接触部及び基板接点部にズレが生じ、接触が不安定になったり、蛍光管を構成するガラス管と電極部との間の不活性ガス封止部に負荷が加わり、封止ガスがリークし、短寿命化をきたす恐れがあった。
そこで本願出願人は先にベース部にハウジングをスライド自在に取り付け、このハウジングにコンタクトの蛍光管電極接触部を取り付け、ベース部に配置した基板との接点部と前記蛍光管電極接触部との間を弾性変形部で連結するソケットを提案した（特許文献１）。
この場合にベース部に対してスライド自在に移動するハウジングを設けたことにより部部品点数が多かった。
部品点数が多いと、金型費、材料費がかさみ、組立工数が増える問題があった。 Fluorescent tubes such as cold cathode fluorescent tubes are well known as backlights used in liquid crystal display devices and the like.
This type of fluorescent tube is mounted on a socket connected to a rigid board. The lighting and extinction of the fluorescent tube make it possible to reduce the relative length of heat between the electrode length at both ends of the fluorescent tube, the socket, the chassis to which the socket is attached, and the board. A difference in expansion and contraction occurs.
If a mechanism for absorbing these thermal expansion / contraction differences is not provided, the contact portion of the electrode of the fluorescent tube and the contact of the socket and the contact portion of the substrate will be displaced, the contact becomes unstable, or the glass tube constituting the fluorescent tube There is a risk that a load is applied to the inert gas sealing portion between the electrode portion and the electrode portion, and the sealing gas leaks to shorten the life.
Therefore, the applicant of the present application first slidably attaches the housing to the base portion, attaches the fluorescent tube electrode contact portion of the contact to the housing, and connects between the contact portion with the substrate disposed on the base portion and the fluorescent tube electrode contact portion. The socket which connects the two with the elastic deformation part was proposed (patent document 1).
In this case, the number of part parts is large due to the provision of the housing that is slidable relative to the base part.
When the number of parts is large, there is a problem that mold costs and material costs increase, and the number of assembly steps increases.

特願２００７−２２９５５８号Japanese Patent Application No. 2007-229558

本発明は蛍光管の点灯及び消灯による熱伸縮の吸収性に優れ、部品点数の低減に効果的な蛍光管用ソケットの提供を目的とする。   An object of the present invention is to provide a socket for a fluorescent tube that is excellent in absorption of thermal expansion and contraction caused by turning on and off the fluorescent tube and is effective in reducing the number of components.

本発明に係る蛍光管用ソケットは、蛍光管を電源に電気接続するためのハウジングと当該ハウジングに収容されたコンタクトを備えたソケットであって、ハウジングは、少なくとも一方に開口したコンタクト収容部を有し、コンタクトは、前記ハウジングのコンタクト収容部に固定するコンタクトベース部と、蛍光管の電極に接触する接触片と、コンタクトベース部に設けられたガイド部とを有し、接触片は、コンタクトベース部と弾性変形部にて連結されているとともに、接触片から延在するスタビライザーを有し、当該スタビライザーの移動が前記ガイド部にてガイドされることを特徴とする。
コンタクトが蛍光管の電極と接触する接触片を、ハウジングに固定するためのコンタクトベース部と弾性変形部で連結したことにより、弾性変形部の変形により蛍光管の点灯及び消灯による熱伸縮を吸収することになるが、接触片の蛍光管軸方向の移動及びそれと直交する略水平方向の移動をガイドしてやらないと接触片の接触安定性に不安が残る。
特に蛍光管が細長い冷陰極蛍光管にあっては蛍光管の軸方向の長さの伸縮差が大きい。
そこで、本発明は接触片から延在するスタビライザーを設け、このスタビライザーの移動をガイドするガイド部をコンタクト自身に設けたものである。 A socket for a fluorescent tube according to the present invention is a socket including a housing for electrically connecting a fluorescent tube to a power source and a contact accommodated in the housing, and the housing has a contact accommodating portion opened at least in one side. The contact includes a contact base portion that is fixed to the contact accommodating portion of the housing, a contact piece that contacts an electrode of the fluorescent tube, and a guide portion that is provided on the contact base portion. And a stabilizer extending from the contact piece, and the movement of the stabilizer is guided by the guide portion.
The contact piece that contacts the electrode of the fluorescent tube is connected to the housing by a contact base portion and an elastically deformable portion, so that the elastic deformation portion deforms to absorb thermal expansion and contraction caused by the lighting and extinction of the fluorescent tube. However, if the movement of the contact piece in the direction of the fluorescent tube axis and the movement in the substantially horizontal direction perpendicular thereto are not guided, the contact stability of the contact piece remains uneasy.
In particular, when the fluorescent tube is an elongated cold cathode fluorescent tube, the difference in expansion and contraction of the axial length of the fluorescent tube is large.
Therefore, the present invention is provided with a stabilizer extending from the contact piece, and a guide portion for guiding the movement of the stabilizer is provided on the contact itself.

請求項２に係る発明は、前記スタビライザーの移動をガイドするガイド部をハウジングに設けた場合で、蛍光管を電源に電気接続するための、ハウジングと当該ハウジングに収容されたコンタクトを備えたソケットであって、ハウジングは、少なくとも一方に開口したコンタクト収容部と、ガイド部とを有し、コンタクトは、前記ハウジングのコンタクト収容部に固定するコンタクトベース部と、蛍光管の電極に接触する接触片とを有し、接触片は、コンタクトベース部と弾性変形部にて連結されているとともに、接触片から延在するスタビライザーを有し、当該スタビライザーの移動が、前記ガイド部にてガイドされることを特徴とする。
また、ここで、前記接触片と前記弾性変形部との間を、弾性変形部に設けられたアーム部によって連結し、接触片とコンタクトベース部との間に生じるねじれ変形を許容し得るようにしてもよい。 The invention according to claim 2 is a socket provided with a housing and a contact accommodated in the housing for electrically connecting the fluorescent tube to a power source when a guide portion for guiding the movement of the stabilizer is provided in the housing. The housing includes a contact accommodating portion that is open at least in one side, and a guide portion, and the contact includes a contact base portion that is fixed to the contact accommodating portion of the housing, and a contact piece that contacts an electrode of the fluorescent tube. The contact piece is connected to the contact base portion and the elastic deformation portion, and has a stabilizer extending from the contact piece, and the movement of the stabilizer is guided by the guide portion. Features.
Further, here, the contact piece and the elastic deformation portion are connected by an arm portion provided in the elastic deformation portion so that the torsional deformation generated between the contact piece and the contact base portion can be allowed. May be.

冷陰極蛍光管の場合には、ガラス管の封止部から突出したジメット線とも称されるリード部を有しているのが一般的であり、ソケットには、このリード部を直接挟持するタイプのものと、リード部からガラス管にまたがるように電極金具を取り付け、この電極金具を介して電気接続するタイプのものがある。
電極金具を用いた場合には、コンタクトの接触部に必ずしもＺＩＦ（Ｚｅｒｏ Ｉｎｓｅｒｔｉｏｎ Ｆｏｒｃｅ）構造やＬＩＦ（Ｌｏｗ Ｉｎｓｅｒｔｉｏｎ Ｆｏｒｃｅ）構造を必要としないが、脆弱なリード部に直接的に電気接続する場合には、ＺＩＦ構造やＬＩＦ構造を採用するのが好ましい。
そのような場合には、コンタクトの接触片を蛍光管の電極に対して開放状態と接触状態とを切り換え保持するカバー部材を有し、カバー部材は、前記接触片接触状態においてハウジングに対して蛍光管軸方向にスライド移動可能であり、且つコンタクトの接触片の移動に追随可能にするとよい。
ここでカバー部材にてコンタクトの接触片をリード部に対して開放状態と接触状態に切り換える手段は特に限定しないが、例えばカバー部材に接触片を外側からリード部側に押圧する傾斜面を設け、カバー部材をハウジングに押し込むことで接触状態に切り換える方法が例として挙げられる。 In the case of a cold cathode fluorescent tube, it is common to have a lead portion also called a zimet wire protruding from the sealing portion of the glass tube, and the socket is a type in which this lead portion is directly sandwiched There is a type that attaches an electrode fitting so as to straddle the glass tube from the lead portion, and is electrically connected via this electrode fitting.
When using electrode fittings, it is not always necessary to have a ZIF (Zero Insertion Force) structure or a LIF (Low Insertion Force) structure at the contact part of the contact, but in the case of direct electrical connection to a fragile lead part It is preferable to adopt a ZIF structure or a LIF structure.
In such a case, the contact member has a cover member for switching and holding the contact piece between the open state and the contact state with respect to the electrode of the fluorescent tube, and the cover member is fluorescent with respect to the housing in the contact piece contact state. It is preferable to be able to slide in the tube axis direction and to follow the movement of the contact piece of the contact.
Here, the means for switching the contact piece of the contact between the open state and the contact state with respect to the lead portion at the cover member is not particularly limited.For example, the cover member is provided with an inclined surface that presses the contact piece from the outside to the lead portion side, An example is a method of switching to a contact state by pushing the cover member into the housing.

本発明に係るソケットにあっては、蛍光管の電極に接触する接触片と、コンタクトをハウジングに固定するためのコンタクトベース部とを弾性変形部で連結するとともにこの接触片から延在するスタビライザーの移動をガイドするガイド部をこのコンタクト自身、あるいはハウジングに設けたことにより、特許文献１に示したベース部とハウジングとを一体的に成形できるようになり、部品点数が減る。
また、接触片と弾性変形部との間を弾性変形部に設けたアーム部によって連結すると、接触片の前後方向の移動のみならず、ねじれ変形も吸収しやすくなる。
さらに、ＺＩＦ構造を採用するためにカバー部材をハウジングに追加した場合にあっては、カバー部材をコンタクトの接触片とともにハウジングに対して移動可能にすることで部品点数の低減を図ることができる。 In the socket according to the present invention, the contact piece that contacts the electrode of the fluorescent tube and the contact base part for fixing the contact to the housing are connected by the elastic deformation part, and the stabilizer extending from the contact piece is provided. By providing the guide itself or the housing with the guide portion for guiding the movement, the base portion and the housing shown in Patent Document 1 can be formed integrally, and the number of parts is reduced.
Further, when the contact piece and the elastic deformation portion are connected by the arm portion provided in the elastic deformation portion, not only the movement of the contact piece in the front-rear direction but also the torsional deformation is easily absorbed.
Further, when a cover member is added to the housing in order to employ the ZIF structure, the number of parts can be reduced by making the cover member movable with respect to the housing together with the contact piece of the contact.

コンタクト１０は、ハウジングに固定するコンタクトベース部１１を有し、このコンタクトベース部１１は図５（ｂ）に示すようにハウジング２０の底部に設けた溝部に差し込む挿入片１２と、ハウジングのコンタクト収容部２３の側壁にランス係止するランス１１ａ，１１ｂを有する。
コンタクト１０は、コンタクトベース部１１の下側に基板接点部１３を有し、この基板接点部１３は図５（ａ）に示すようにハウジングの基板挿入口２２に位置する。
コンタクトベース部１１から上方に向けて立設した帯状のアーム形状からなる弾性変形部１６を有し、この弾性変形部１６の上部付近から逆Ｕ字状に折り返したアーム部１５ａ，１５ｂを有する。
アーム部１５ａ，１５ｂの先端部は、対向立設した一対の接触片１４ａ，１４ｂと連結されている。
一対の接触片の根元に位置する支持部１７ａから前方側（蛍光管装着側）に立設した立設片１７の左右両側を平面視略コ字に折り曲げ、この折り曲げ部１７ｂから外側に向けて突出延在したスタビライザー１８を左右に対向して一対有する。
コンタクトベース部１１からは、左右一対のガイド部１９を立設してあり、ガイド部１９に設けたガイド孔１９ａにてスタビライザー１８の移動をガイドする。
ガイド孔１９は概ね前後方向に水平な長孔であり、接触片１４ａ，１４ｂが弾性変形部１６の変形により、前後方向（蛍光管の軸方向）に移動する際に、このスタビライザー１８の移動をガイドすることで図６に示すように安定した変形になる。

一対の接触片１１４ａ，１１４ｂは開放状態では蛍光管２のリード部２ｂに接触しないように間隔をあけて立設している。
カバー部材１３０を下方に押し込むと、カバー部材１３０の傾斜面１３４によって接触片１１４ａ，１１４ｂが対向する内側に押圧され、リード部２ｂに接触し垂直面１３５にて押圧保持する。
押圧されたカバー部材１３０はその係合爪１３３がハウジングに設けた被係合部１２８に係合する。
カバー部材１３０はスライドリブ１３２がハウジングのガイドリブ１２５に摺接し、図９に示すようにコンタクトのスタビライザー１１８がハウジングのガイド部１２７により移動がガイドされる。
これにより、図１０に示すように、蛍光管の熱膨張によりリード部２ｂが図１０にて右側に移動するとコンタクト１１０の弾性変形部１１６が変形し、接触片１１４ａ，１１４ｂが移動する。
この際に接触片を支持するスタビライザー１１８がガイド部１２７にガイドされながら右側に移動し、この移動に追随してカバー部材１３０は移動する。
この際にカバー部材１３０に設けたスライドリブ１３２とハウジングのガイドリブ１２５が摺接移動する。 The cover member 130 has a contact piece accommodating portion 131a in a resin cover housing 131.
The side wall of the cover housing 131 has a pair of slide ribs 132 and an engaging claw 133 protruding outward.
As shown in FIG. 8, the contact piece accommodating portion 131 a of the cover member 130 has an inclined surface 134 that spreads outward toward the lower side and a vertical surface 135 that presses and holds the contact piece on the upper side.
The pair of contact pieces 114a and 114b are erected at intervals so as not to contact the lead portion 2b of the fluorescent tube 2 in the open state.
When the cover member 130 is pushed downward, the contact pieces 114a and 114b are pressed inwardly by the inclined surface 134 of the cover member 130, contact the lead portion 2b, and are pressed and held by the vertical surface 135.
The pressed cover member 130 has its engaging claw 133 engaged with the engaged portion 128 provided in the housing.
In the cover member 130, the slide rib 132 is in sliding contact with the guide rib 125 of the housing, and the movement of the stabilizer 118 of the contact is guided by the guide portion 127 of the housing as shown in FIG. 9.
Accordingly, as shown in FIG. 10, when the lead portion 2b moves to the right side in FIG. 10 due to thermal expansion of the fluorescent tube, the elastic deformation portion 116 of the contact 110 is deformed, and the contact pieces 114a and 114b move.
At this time, the stabilizer 118 that supports the contact piece moves to the right while being guided by the guide 127, and the cover member 130 moves following this movement.
At this time, the slide rib 132 provided on the cover member 130 and the guide rib 125 of the housing are slidably moved.
