Description

この発明は、主に照明用の光源として用いられるねじ込み式の白熱電球または電球形蛍光灯に用いられるランプに関するものである。   The present invention relates to a lamp used for a screw-in type incandescent bulb or a bulb-type fluorescent lamp mainly used as a light source for illumination.

従来図２６に示すように、白熱電球あるいは電球形蛍光灯のねじ込み式の口金は、銅板にしぼり加工を施して形成された全周がねじ部１００となり、かつ全周が導電部であった。中心接点部１０１は、リード線を接続する半田の山にて形成されていた。１０２はランプバルブや電球形蛍光灯のケースである。   Conventionally, as shown in FIG. 26, the screw-type base of the incandescent bulb or the bulb-type fluorescent lamp has a screw portion 100 formed around the copper plate, and the entire periphery is a conductive portion. The center contact portion 101 was formed by a solder pile connecting the lead wires. Reference numeral 102 denotes a lamp bulb or bulb-type fluorescent lamp case.

受金を有するランプソケット１０３は、ねじ部を樹脂などで形成し、その側面の一部に弾性片からなる導電部１０４を配置した部分受金であった。中心接触部は、弾性片からなる導電板１０５であった。   The lamp socket 103 having a metal receiver is a partial metal receiver in which a threaded portion is formed of resin or the like and a conductive portion 104 made of an elastic piece is disposed on a part of the side surface. The central contact portion was a conductive plate 105 made of an elastic piece.

なお、部分受金ではなく、口金と同様にしぼり加工した全周受金のものもあった。   In addition, there was also a thing of the all-round receipt which carried out the squeeze process like a nozzle | cap | die rather than a partial receipt.

ランプソケット１０３の受金の導電部１０４や導電板１０５の弾性片の変形によって接触荷重を与える構造である部分受金や中心接触部では、ランプバルブや電球形蛍光灯のケースがランプソケット１０３の口縁に当たって奥まで挿入できないので、中心接触片となる導電板１０５が疲労した場合など、導電板１０５の弾性変形によって接触が不十分になる可能性がある。特にランプを交換した場合は、ランプ寸法のばらつきによって、ランプ交換後のランプでは接触が不十分となる。   The lamp bulb and the bulb-type fluorescent lamp case are attached to the lamp socket 103 at the partial receptacle or the central contact portion, which is configured to apply a contact load by deformation of the conductive portion 104 of the receptacle of the lamp socket 103 and the elastic piece of the conductive plate 105. Since it cannot be inserted into the back as it hits the lip, contact may become insufficient due to elastic deformation of the conductive plate 105, such as when the conductive plate 105 serving as the center contact piece is fatigued. In particular, when the lamp is replaced, contact with the lamp after the lamp replacement is insufficient due to variations in lamp dimensions.

また、口金のしぼり加工は難しく生産性も悪く、口金の板厚も薄くなるため強度不足になり、ねじ込み操作によりねじ山がつぶれる恐れがあった。   In addition, it is difficult to squeeze the base, the productivity is poor, the plate thickness of the base becomes thin, the strength is insufficient, and the screw thread may be crushed by the screwing operation.

そこで本発明の目的は、ランプ交換をしても常に確実に接続可能であり、また加工が容易で、接触の信頼性が高く、コストのかからないねじ込み式のランプを提供することである。   Accordingly, an object of the present invention is to provide a screw-in type lamp that can always be reliably connected even after lamp replacement, is easy to process, has high contact reliability, and is inexpensive.

この発明のランプは、ねじ込み型のランプソケットに螺合する口金部および出光部を有するランプであって、前記口金部は、外周面に形成したねじ部および前記ねじ部の周方向に複数形成された窓孔を有する有底円筒形の本体と、前記窓孔内に位置する複数の導電部と、前記本体内の前記複数の導電部の両端部に位置する一対のリング部とを有し、前記一対のリング部は前記一対のリング部の周方向に前記複数の導電部の端部が連結されることにより前記複数の導電部の前記端部同士を連結して前記導電部を支持し、前記導電部は前記本体の径方向に弾性を有するものである。 The lamp of the present invention is a lamp having a base portion and a light emitting portion that are screwed into a screw-type lamp socket, and the base portion is formed in a plurality of screw portions formed on the outer peripheral surface and in the circumferential direction of the screw portion. A bottomed cylindrical main body having a window hole, a plurality of conductive parts located in the window hole, and a pair of ring parts located at both ends of the plurality of conductive parts in the main body, The pair of ring portions supports the conductive portion by connecting the ends of the plurality of conductive portions by connecting ends of the plurality of conductive portions in a circumferential direction of the pair of ring portions, The conductive portion has elasticity in the radial direction of the main body.

この発明の別のランプは、ねじ込み型のランプソケットに螺合する口金部および出光部を有するランプであって、前記口金部は、外周面に形成したねじ部および前記ねじ部の周方向に複数形成された窓孔を有する有底円筒形の本体と、前記窓孔内に位置する複数の導電部と、前記本体内の前記複数の導電部の一端部に位置するリング部とを有し、前記リング部は前記リング部の周方向に前記複数の導電部の前記一端部が連結されることにより前記導電部の前記一端部同士を連結して前記導電部を支持し、前記導電部は前記本体の径方向に弾性を有するものである。 Another lamp according to the present invention is a lamp having a base portion and a light emitting portion that are screwed into a screw-type lamp socket, and the base portion includes a screw portion formed on an outer peripheral surface and a plurality of circumferential portions of the screw portion. A bottomed cylindrical main body having a formed window hole, a plurality of conductive parts located in the window hole, and a ring part located at one end of the plurality of conductive parts in the main body, The ring part supports the conductive part by connecting the one end parts of the conductive parts by connecting the one end parts of the plurality of conductive parts in the circumferential direction of the ring part, It has elasticity in the radial direction of the main body.

この発明のランプによれば、口金側の導電部が弾性を持っているため、受金側の弾性接触片がへたった場合においても、十分な接触が得られる。このように、ランプ口金とソケット受金の接続の接触荷重を与える機能を、消耗品であるランプ口金に設けることで、ランプ交換をしても常に確実に接続可能となる。また導電部は加工容易で接触の信頼性が高く省材料でコストがかからない。さらにリング部で繋がれた複数の導電部を本体に単にはめ込むだけで組み立てることができるため、口金部の組み立てが容易になる。   According to the lamp of the present invention, since the conductive part on the base side has elasticity, sufficient contact can be obtained even when the elastic contact piece on the receiving side is bent. In this way, by providing the lamp base, which is a consumable item, with the function of giving a contact load for the connection between the lamp base and the socket base, it is always possible to reliably connect even if the lamp is replaced. Also, the conductive part is easy to process, has high contact reliability, saves material, and does not cost. Further, since the plurality of conductive parts connected by the ring part can be assembled simply by fitting them into the main body, the base part can be easily assembled.

この発明の第１の実施の形態を図２および図１２により説明する。すなわち、このランプは、ねじ込み型のランプソケットに螺合する口金部２および出光部１を有するランプである。出光部１は白熱灯ランプのバルブまたは電球形蛍光灯のケースおよびグローブなどがある。   A first embodiment of the present invention will be described with reference to FIGS.

The light emitting unit 1 includes an incandescent lamp bulb or a bulb-type fluorescent lamp case and a globe.

口金部２はねじ部３と、ねじ部３の周面に設けた弾性体からなる導電部４を有する。導電部４は口金部２の径方向に弾性を有するものであり、ねじ込み軸方向に部分的に形成され、ねじ部３に軸方向の凹溝５を形成し、ねじ込み軸方向の導電部４は凹溝５に嵌まる略長方形の板金により形成されている。   The base part 2 has a screw part 3 and a conductive part 4 made of an elastic body provided on the peripheral surface of the screw part 3. The conductive portion 4 has elasticity in the radial direction of the base portion 2 and is partially formed in the screwing axial direction, and an axial concave groove 5 is formed in the screw portion 3, and the conductive portion 4 in the screwing axial direction is It is formed of a substantially rectangular sheet metal that fits into the groove 5.

実施の形態の口金部２は樹脂製であり、ねじ部３を一体形成している。またねじ部３の軸方向に凹溝５を形成し、凹溝５内に導電部４を配置し、導電部４の一端のリード部７が口金部２内に貫設されて支持され、導電部４をねじ部３の表面より突出している。中心接点部６は導電体例えば金属により形成され、中央に突出したリード部８が口金部２に貫設している。なお、リード部７、８がランプフィラメントに接続される。   The base part 2 of the embodiment is made of resin, and the screw part 3 is integrally formed. Further, a concave groove 5 is formed in the axial direction of the screw portion 3, the conductive portion 4 is disposed in the concave groove 5, and a lead portion 7 at one end of the conductive portion 4 is penetrated and supported in the base portion 2, and conductive The part 4 protrudes from the surface of the screw part 3.

The lead portions 7 and 8 are connected to the lamp filament.

第１の実施の形態によれば、口金側の導電部４が弾性を持っているため、受金側の弾性接触片がへたった場合においても、十分な接触が得られる。このように、ランプ口金とソケット受金の接続の接触荷重を与える機能を、消耗品であるランプ口金に設けることで、ランプ交換をしても常に確実に接続可能である。また導電部４は加工が容易で、接触の信頼性が高く、省材料でコストがかからない。板金は順送加工できるため、口金のしぼり加工に比べて加工工数が少なくできる。   According to the first embodiment, since the base-side conductive portion 4 has elasticity, sufficient contact can be obtained even when the elastic-side contact piece on the receiving side is bent. In this way, by providing the lamp base, which is a consumable item, with the function of giving a contact load for the connection between the lamp base and the socket base, it is possible to always connect reliably even when the lamp is replaced. Further, the conductive portion 4 is easy to process, has high contact reliability, saves material, and does not cost. Since sheet metal can be processed progressively, the number of processing steps can be reduced as compared with the process of squeezing the die.

この発明の第２の実施の形態を図３により説明する。すなわち、このランプは、導電部４が弾性のある導電性樹脂であり、柔軟性をもっている。口金部２の本体は樹脂製で有底円筒形に形成され、導電部４がその外周面に設けられ、かつねじ山を形成している。その他は第１の実施の形態と共通し、共通部分には同一符号を付している。   A second embodiment of the present invention will be described with reference to FIG.

That is, in this lamp, in the first embodiment, the screw portion 3 and the conductive portion 4 are combined with a corrugated elastic sheet metal. The base part 2 is formed in a bottomed cylindrical shape with a synthetic resin, the lead part 7 at one end of the conductive part 4 is supported by penetrating from the outer peripheral surface of the base part 2, and the other end side protrudes outward. In this way, elasticity is imparted.

なお、この実施の形態では１個の弾性の板金を用いたが、複数設けてもよい。   In this embodiment, one elastic sheet metal is used, but a plurality of elastic sheet metals may be provided.

この発明の第４の実施の形態を図５により説明する。すなわち、このランプは、口金部２において、その本体を形成する合成樹脂によりねじ部３を形成し、導電部４は弾性のある導電性の樹脂または金属によりねじ部３に位置しねじ部３のねじ山に整合するねじ山のあるリング部１１と、このリング部１１から中心接点部６の近傍に延びかつねじ山のある１または複数の延出部１２により形成している。   A fourth embodiment of the present invention will be described with reference to FIG.

That is, in this lamp, in the base part 2, the base body is formed of a synthetic resin in a bottomed cylindrical shape, a peripheral groove 13 is formed on the outer peripheral surface, and the peripheral groove 13 is combined with the screw part 3 and the conductive part 4. A ring-shaped elastic piece 15 having elasticity in the direction is disposed. The elastic piece 15 is, for example, a metal threaded ring, has a substantially C shape corresponding to the partial socket of the lamp socket, and is formed through a hole 16 in which a central central lead portion 17 is formed in the circumferential groove 13. And allows connection to the lamp filament.

この口金部２をランプソケットにねじ込むことにより、弾性片１５が径方向に弾性変形し、ランプソケットの受け金に弾性接触することができる。なお弾性片１５のねじ山は１周分のみでもよい。その他、第１の実施の形態と共通する。   By screwing the cap portion 2 into the lamp socket, the elastic piece 15 is elastically deformed in the radial direction, and can be elastically contacted with the lamp socket receptacle. The thread of the elastic piece 15 may be only one round. In addition, it is common to the first embodiment.

この発明の第６の実施の形態を図７から図９により説明する。すなわち、このランプは電球形蛍光灯であり、口金部２に点灯回路２０を内蔵し、点灯回路２０の基板２１の一側面または両側面を口金部２の一部としている。実施の形態では、合成樹脂製の口金部２の周面に軸方向の一対の凹溝５をスリット状に貫通形成し、基板２１の一部を口金部２内に挿入し、基板２１の挿入部分の両側を凹溝５に嵌合して外部に露出している。この基板２１の挿入部分の両側にねじ部３および導電部４が設けられる。ねじ部３および導電部４は弾性のある導電性樹脂によりねじ山の断面に相当する波形に形成し、口金部２の外周面よりも突出した状態に形成している。あるいは基板２１にねじ山の断面に相当する波形に形成し、その表面に弾性のある導電性樹脂を設けるようにしてもよい。   A sixth embodiment of the present invention will be described with reference to FIGS. That is, this lamp is a light bulb-type fluorescent lamp, and the lighting circuit 20 is built in the base part 2, and one side surface or both side surfaces of the substrate 21 of the lighting circuit 20 are part of the base part 2. In the embodiment, a pair of axially recessed grooves 5 are formed in a slit shape on the peripheral surface of the base portion 2 made of synthetic resin, a part of the substrate 21 is inserted into the base portion 2, and the substrate 21 is inserted. Both sides of the portion are fitted in the groove 5 and exposed to the outside. The screw part 3 and the conductive part 4 are provided on both sides of the insertion part of the substrate 21. The screw part 3 and the conductive part 4 are formed in a corrugated shape corresponding to the cross section of the screw thread by an elastic conductive resin, and are formed so as to protrude from the outer peripheral surface of the base part 2. Alternatively, the substrate 21 may be formed in a waveform corresponding to the cross section of the thread, and an elastic conductive resin may be provided on the surface thereof.

基板２１の口金部２に挿入されていない部分はケース２２とカバー２３で外周を被覆される。ケース２２とカバー２３は相合わせて１つのホッパー形をなすものであり、ホッパー形状のものを縦に２分割したものに相当する。ケース２２およびカバー２３の小径部側は口金部２に嵌合する嵌合部２４を有し、大径部側はサポート部２５が嵌合し、これにより口金部２とサポート部２５を連結するとともに、ケース２２およびカバー２３で基板２１の全体を覆う。サポート部２５は３本のＵ形ランプバルブ２６の両端部が装着されている。バルブ２６の電極と基板２１とが配線され、また基板２１と中心接点部６が配線される。   A portion of the substrate 21 that is not inserted into the base portion 2 is covered with a case 22 and a cover 23 on the outer periphery. The case 22 and the cover 23 are combined to form one hopper shape, and corresponds to a hopper-shaped one divided vertically into two. The small-diameter side of the case 22 and the cover 23 has a fitting part 24 that fits into the base part 2, and the support part 25 is fitted into the large-diameter part side, thereby connecting the base part 2 and the support part 25. At the same time, the entire substrate 21 is covered with the case 22 and the cover 23. The support portion 25 is attached to both ends of three U-shaped lamp bulbs 26. The electrode of the valve 26 and the substrate 21 are wired, and the substrate 21 and the central contact portion 6 are wired.

第６の実施の形態によれば、口金部２をランプソケットに挿入すると受け金のねじ溝に基板２１の導電部の波形の山が螺合することとなる。したがって、点灯回路２０の基板２１にランプソケットの受け金が直接接触するため、接続個所が減り接触の信頼性が高くなり、また導電部４と基板２１との間の電線の接続が不用なためコストも有利である。   According to the sixth embodiment, when the base portion 2 is inserted into the lamp socket, the corrugated crest of the conductive portion of the substrate 21 is screwed into the screw groove of the base. Accordingly, since the lamp socket holder comes into direct contact with the substrate 21 of the lighting circuit 20, the number of connection points is reduced and the reliability of the contact is increased, and the connection of the electric wire between the conductive portion 4 and the substrate 21 is unnecessary. Cost is also advantageous.

なお、ねじ部３および導電部４は基板２１の両側を波形にし、そこに金属片を貼り付け、口金部２の凹溝５からのぞかせるようにしてもよい。また波形によるねじ山は少なくとも１つでもよい。   Note that the screw portion 3 and the conductive portion 4 may be corrugated on both sides of the substrate 21, and a metal piece may be attached thereto so that the screw portion 3 and the conductive portion 4 can be seen from the concave groove 5 of the base portion 2. Further, at least one screw thread may be used.

この発明の第７の実施の形態を図１０により説明する。すなわち、このランプは、第６の実施の形態において、基板２１の側面に導電部４として略長方形のばね性の板金の一端を取付け、他端側を外方に傾斜させている。口金部２は外周にねじ山を形成したねじ部３を有する。基板２１を口金部２２に挿入すると凹溝５より導電部４が突出しランプソケットの受け金に弾性接触する。   A seventh embodiment of the present invention will be described with reference to FIG. That is, in the sixth embodiment, in the sixth embodiment, one end of a substantially rectangular spring-like sheet metal is attached to the side surface of the substrate 21 as the conductive portion 4, and the other end is inclined outward. The base portion 2 has a screw portion 3 having a thread formed on the outer periphery. When the substrate 21 is inserted into the base portion 22, the conductive portion 4 protrudes from the concave groove 5 and elastically contacts the lamp socket receptacle.

この発明の第８の実施の形態を図１１により説明する。すなわち、このランプは、第６の実施の形態において、ねじ部３および導電部４として導電性樹脂に代えて、ねじ山に対応する波状の板金の一端を基板２１の側面に取付け、外方に弾性を付与するように突出している。   An eighth embodiment of the present invention will be described with reference to FIG. That is, in the sixth embodiment, in the sixth embodiment, instead of the conductive resin as the screw portion 3 and the conductive portion 4, one end of the corrugated sheet metal corresponding to the screw thread is attached to the side surface of the substrate 21, and outwardly. It protrudes to give elasticity.

この発明の第９の実施の形態を図１および図１３から図１４により説明する。すなわち、このランプは、第１の実施の形態において、口金部２は樹脂製であり、ねじ部３に複数の窓孔３０を形成し、窓孔３０に導電部４を有する。複数の導電部４はそれぞれ板ばねにより形成され、各両端部が同方向に折曲され、両端部の先端が弾性のリング部３１、３２により連結されて、導電部４の板厚方向の外向きに弾性を付与している。導電部４の表面は図１３（ａ）に示すように口金本体のねじ部３のねじ山３ａと谷３ｂとの間に相当する位置に位置決めされ、同図（ｂ）のようにランプソケットへねじ込まれることにより、口金部２の導電部４がランプソケットの受け金３４のねじ山と接触して内側に押されてねじ部３の谷３ｂの位置に後退している。このとき導電部４の弾性により受け金３４のねじ山との間に接触圧が生じている。   A ninth embodiment of the present invention will be described with reference to FIGS. 1 and 13 to 14. That is, in this lamp, in the first embodiment, the base part 2 is made of resin, a plurality of window holes 30 are formed in the screw part 3, and the conductive part 4 is provided in the window hole 30. Each of the plurality of conductive portions 4 is formed by a leaf spring, and both end portions thereof are bent in the same direction, and ends of both end portions are connected by elastic ring portions 31 and 32 so that the conductive portion 4 is exposed in the plate thickness direction. Elasticity is given to the direction. As shown in FIG. 13 (a), the surface of the conductive portion 4 is positioned at a position corresponding to the space between the thread 3a and the valley 3b of the screw portion 3 of the base body, and to the lamp socket as shown in FIG. 13 (b). By being screwed in, the conductive portion 4 of the base portion 2 comes into contact with the screw thread of the lamp socket base 34 and is pushed inward to retreat to the position of the valley 3 b of the screw portion 3. At this time, contact pressure is generated between the threads of the receiving metal 34 due to the elasticity of the conductive portion 4.

この発明の第１０の実施の形態を図１５により説明する。すなわち、このランプは、第９の実施の形態において、導電部４を板ばねにより形成し、その一端側のみをリング部３６で連結している。製造方法は板金によりリング部３６とリング部３６から外方に延出した複数の導電部４とを打抜き形成し、導電部４の付根を折曲しかつ段曲げして各導電部４を垂直にし、これにより導電部４に板厚方向に弾性を付与している。   A tenth embodiment of the present invention will be described with reference to FIG. That is, in this lamp, in the ninth embodiment, the conductive portion 4 is formed by a leaf spring, and only one end side thereof is connected by the ring portion 36. In the manufacturing method, the ring portion 36 and the plurality of conductive portions 4 extending outward from the ring portion 36 are punched and formed by sheet metal, and the roots of the conductive portions 4 are bent and stepped to make each conductive portion 4 vertical. Thus, the conductive portion 4 is given elasticity in the thickness direction.
