Description

本発明は給電部材および車両用灯具に関する。より詳しくは、半導体発光素子を光源とする車両用灯具に電源からの電力を供給する給電部材、および当該給電部材を備えた車両用灯具に関する。   The present invention relates to a power supply member and a vehicle lamp. More specifically, the present invention relates to a power supply member that supplies power from a power source to a vehicle lamp using a semiconductor light emitting element as a light source, and a vehicle lamp including the power supply member.

一般に、電源供給ラインにおいて電線に代えてバスバーと称される細長い棒状の導体（例えば金属板）が広く用いられている。例えば自動車用途においては、ストップランプ等の車両用灯具の内部に配される発光ダイオードなどの半導体発光素子に電源からの電力を供給するためのバスバーが知られている（例えば特許文献１を参照）。
特開２００１−６３４５４号公報参照 In general, an elongated bar-like conductor (for example, a metal plate) called a bus bar is widely used instead of an electric wire in a power supply line. For example, in an automotive application, a bus bar for supplying power from a power source to a semiconductor light emitting element such as a light emitting diode disposed inside a vehicle lamp such as a stop lamp is known (see, for example, Patent Document 1). .
See JP 2001-63454 A

発光ダイオードを用いたストップランプ等の車両用灯具は、ノイズにより瞬間的に点灯することが考えられる。   A vehicle lamp such as a stop lamp using a light emitting diode may be turned on instantaneously due to noise.

このようなノイズによる瞬時点灯の発生を防ぐ方法としては、発光ダイオードの点灯回路にコンデンサ等を設ける方法がある。しかしながら、ラインノイズが発生し易い車種とそうでない車種に用いる車両用灯具で、それぞれ点灯回路の回路構成を変更する必要があることから、かかる対策は一方では部品の共通化の阻害要因であった。   As a method for preventing the occurrence of instantaneous lighting due to such noise, there is a method of providing a capacitor or the like in the lighting circuit of the light emitting diode. However, since it is necessary to change the circuit configuration of the lighting circuit for vehicle lamps used for vehicle types that are likely to generate line noise and for vehicles that do not, such measures are, on the other hand, an obstacle to the commonality of parts. .

上記課題を解決するためになされた本発明の一の形態は、半導体発光素子を光源とする車両用灯具に電源からの電力を供給する給電部材であって、前記電源の正極側に接続される正側接続部、および前記電源の負極側に接続される負側接続部を有し、前記半導体発光素子と、前記電源の正極側および負極側とを電気的に接続するバスバーと、前記バスバーに固定されることにより、少なくとも一つの電子部品を前記バスバーにおける前記正側接続部側と前記負側接続部側との間に介装する介装部材とを備えることを特徴とする。   One form of the present invention made to solve the above-described problem is a power supply member that supplies power from a power source to a vehicular lamp using a semiconductor light emitting element as a light source, and is connected to the positive electrode side of the power source. A bus bar having a positive side connection part and a negative side connection part connected to the negative electrode side of the power source, and electrically connecting the semiconductor light emitting element and the positive electrode side and the negative electrode side of the power source; By being fixed, it is provided with an interposition member that interposes at least one electronic component between the positive connection portion side and the negative connection portion side of the bus bar.

このような給電部材によれば、バスバーの形状やバスバー上に配された回路素子の配置などを変更することなくコンデンサなどの電子部品を追加することができる。したがって、例えばラインノイズが発生し易い車種の車両用灯具に用いられる給電部材にラインノイズ対策用のコンデンサを容易に追加することができる。   According to such a power supply member, an electronic component such as a capacitor can be added without changing the shape of the bus bar and the arrangement of the circuit elements arranged on the bus bar. Therefore, for example, a line noise countermeasure capacitor can be easily added to a power supply member used in a vehicle lamp of a vehicle type in which line noise is likely to occur.

また、上記給電部材は、前記バスバーを固定するベース部材を更に備え、前記正側接続部および前記負側接続部の一部は、前記ベース部材から突出したコネクタを構成し、前記介装部材は、前記正側接続部および前記負側接続部の近傍に設けられることが好ましい。   Further, the power supply member further includes a base member for fixing the bus bar, a part of the positive side connection part and the negative side connection part constitutes a connector protruding from the base member, and the interposed member is It is preferable to be provided in the vicinity of the positive side connecting part and the negative side connecting part.

正側接続部および負側接続部の一部がこのようにベース部材から突出したコネクタである場合、介装部材をコネクタ部分に設ければ、正側接続部と負側接続部との間に容易に介装部材を接続することができる。   When a part of the positive side connecting part and the negative side connecting part is a connector protruding from the base member in this way, if the interposition member is provided in the connector part, it is between the positive side connecting part and the negative side connecting part. The intervention member can be easily connected.

また、前記介装部材は、導電材料により形成され、前記正側接続部と電気的に接続される正側ターミナル部と、導電材料により形成され、前記負側接続部と電気的に接続される負側ターミナル部と、絶縁材料により形成され、前記正側ターミナル部と前記負側ターミナル部とを絶縁保持した状態で前記バスバーに固定されるハウジング部とを有する。   The interposition member is made of a conductive material, and is formed of a conductive terminal and electrically connected to the positive side connecting portion, and is electrically connected to the negative side connecting portion. A negative terminal portion; and a housing portion formed of an insulating material and fixed to the bus bar in a state where the positive terminal portion and the negative terminal portion are insulated and held.

介装部材がこのような構成を有することにより、介装部材を取り付けたときにバスバーの正側接続部側と負側接続部側とがショートするのを防ぐことができる。   When the interposition member has such a configuration, it is possible to prevent the positive side connection portion side and the negative side connection portion side of the bus bar from being short-circuited when the interposition member is attached.

また、前記正側ターミナル部および前記負側ターミナル部は、かしめ構造により前記電子部品を固定するかしめ端子を有することが好ましい。   Moreover, it is preferable that the said positive side terminal part and the said negative side terminal part have a crimping terminal which fixes the said electronic component by a crimping structure.

これにより、電子部品を半田付けによらずに介装部材に固定することができるので、組み立てが容易となる。また、半田を使用しない方法としては、溶接、圧接、端子へのはめ込みといった方法も考えられる。   Thereby, since an electronic component can be fixed to an interposed member without using soldering, assembly is facilitated. In addition, as a method not using solder, methods such as welding, pressure welding, and fitting into terminals are also conceivable.

以下、発明の実施の形態を通じて本発明を説明するが、以下の実施形態は特許請求の範囲にかかる発明を限定するものではない。また、実施形態の中で説明されている特徴の組み合わせの全てが発明の解決手段に必須であるとは限らない。   Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

図1は、給電部材１０の斜視図である。また、図２は、給電部材１０の上面図であり、図３は、給電部材１０の回路構成を示す模式図である。給電部材１０は、バスバー２０と、バスバー２０を固定するベース部材３０と、電子部品２００が固定された介装部材１００とを備える。本実施形態の給電部材１０は、例えば乗用車のハイマウントストップランプの光源に電源からの電力を供給するためのパーツとして用いられる。   FIG. 1 is a perspective view of the power supply member 10. FIG. 2 is a top view of the power supply member 10, and FIG. 3 is a schematic diagram illustrating a circuit configuration of the power supply member 10. The power supply member 10 includes a bus bar 20, a base member 30 that fixes the bus bar 20, and an interposed member 100 to which the electronic component 200 is fixed. The power supply member 10 of the present embodiment is used as a part for supplying power from a power source to a light source of a high-mount stop lamp of a passenger car, for example.

バスバー２０は、銅板等の板状の導電材料により形成されており、ネジあるいは係合爪（何れも不図示）などを介してベース部材３０に固定される。ベース部材３０は、樹脂等の絶縁材料により形成されており、略直方体の形状を有する。本例において、バスバー２０は、例えば板金等の方法により製造される。また、ベース部材３０は、例えば射出成型等の方法により製造される。   The bus bar 20 is made of a plate-like conductive material such as a copper plate, and is fixed to the base member 30 via a screw or an engaging claw (both not shown). The base member 30 is made of an insulating material such as resin and has a substantially rectangular parallelepiped shape. In this example, the bus bar 20 is manufactured by a method such as sheet metal. The base member 30 is manufactured by a method such as injection molding.

バスバー２０は、連結部２８により連結された複数の導電部２３を有する。それぞれの導電部２３は、ベース部材３０の上面に固定された部分（水平部分）と、長手方向に延びるベース部材３０の近傍において立ち上がった部分（垂直部分）とを有する。なお、複数の導電部２３を連結する連結部２８は、給電部材１０の製造工程において最終的には取り除かれるものであるが、本実施形態では説明の便宜上、連結部２８を残した状態を図示して説明するものとする。   The bus bar 20 has a plurality of conductive parts 23 connected by a connecting part 28. Each conductive portion 23 has a portion (horizontal portion) fixed to the upper surface of the base member 30 and a portion (vertical portion) rising in the vicinity of the base member 30 extending in the longitudinal direction. In addition, although the connection part 28 which connects the some electroconductive part 23 is finally removed in the manufacturing process of the electric power feeding member 10, in this embodiment, the state which left the connection part 28 is shown for convenience of explanation. It shall be shown and described.

バスバー２０における一の導電部２３の水平部分と他の導電部２３の水平部分との間には、ダイオード２４、抵抗２５、および発光ダイオード５０が固定されている。これらの電子部品は、例えばそれぞれの導電部２３の一部をかしめることにより固定される。なお、これらの電子部品を圧接、半田付け、あるいは溶着などの方法で導電部２３に固定してもよい。なお、発光ダイオード５０は、本発明の半導体発光素子の一例である。   A diode 24, a resistor 25, and a light emitting diode 50 are fixed between the horizontal portion of one conductive portion 23 and the horizontal portion of the other conductive portion 23 in the bus bar 20. These electronic components are fixed, for example, by caulking a part of each conductive portion 23. Note that these electronic components may be fixed to the conductive portion 23 by a method such as pressure welding, soldering, or welding. The light emitting diode 50 is an example of the semiconductor light emitting element of the present invention.

バスバー２０におけるベース部材３０の前縁側に垂直部分を有する二つの導電部２３の一方は、ベース部材３０の長手方向における略中央部に正側接続部２１を有し、他方は、正側接続部２１と連結部２８を介して連結する部分に負側接続部２２を有する。正側接続部２１および負側接続部２２は、それぞれ、電源（不図示）の正極側と負極側に給電線等の導電部材を介して接続される。ここで、電源とは、例えば自動車用のバッテリーなどの直流電源である。   One of the two conductive portions 23 having a vertical portion on the front edge side of the base member 30 in the bus bar 20 has a positive side connection portion 21 at a substantially central portion in the longitudinal direction of the base member 30, and the other is a positive side connection portion. A negative side connection portion 22 is provided at a portion connected to 21 through a connection portion 28. The positive side connecting part 21 and the negative side connecting part 22 are respectively connected to a positive electrode side and a negative electrode side of a power source (not shown) via a conductive member such as a power supply line. Here, the power source is a direct current power source such as an automobile battery.

介装部材１００は、電子部品２００を保持し、給電部材１０の製造時にバスバー２０の前縁側の垂直部分における正側接続部２１および負側接続部２２の位置、すなわちバスバー２０の前縁側の中央部（図１および図２にＡで示す位置）に取り付けられる。これにより、図３に回路構造として示すように、バスバー２０における複数の導電部２３、ダイオード２４、抵抗２５、および発光ダイオード５０により構成される点灯回路における正側接続部２１側と負側接続部２２側との間に電子部品２００が介装される。   The interposition member 100 holds the electronic component 200, and the positions of the positive side connection portion 21 and the negative side connection portion 22 in the vertical portion on the front edge side of the bus bar 20 when the power supply member 10 is manufactured, that is, the center on the front edge side of the bus bar 20. It is attached to the part (position shown by A in FIGS. 1 and 2). Accordingly, as shown in FIG. 3 as a circuit structure, the positive side connection portion 21 side and the negative side connection portion in the lighting circuit constituted by the plurality of conductive portions 23, the diode 24, the resistor 25, and the light emitting diode 50 in the bus bar 20. The electronic component 200 is interposed between the 22 side.

本例では、電子部品２００はコンデンサであり、給電部材１０に設けられる点灯回路に外部から侵入するラインノイズをフィルタリングする。このように、本実施形態の給電部材１０は、介装部材１００を用いて電子部品２００（コンデンサ）を点灯回路に対して並列に接続することができる。したがって、バスバー２０などの設計変更をすることなくラインノイズ対策の改良などを行うことができる。   In this example, the electronic component 200 is a capacitor, and filters line noise that enters the lighting circuit provided in the power supply member 10 from the outside. As described above, the power supply member 10 of the present embodiment can connect the electronic component 200 (capacitor) in parallel to the lighting circuit using the interposition member 100. Therefore, it is possible to improve line noise countermeasures without changing the design of the bus bar 20 or the like.

図４は、介装部材１００の分解斜視図である。また、図５は、介装部材１００の組み立て後の斜視図であり、図６は、介装部材１００がバスバー２０の前縁側の中央部に取り付けられたときの様子を示す図である。   FIG. 4 is an exploded perspective view of the intervention member 100. 5 is a perspective view after assembling the interposition member 100, and FIG. 6 is a view showing a state when the interposition member 100 is attached to the central portion on the front edge side of the bus bar 20.

図４に示すように、介装部材１００は、ステンレス板等の板状の導電材料により形成される正側ターミナル部１１０および負側ターミナル部１２０と、プラスチック等の絶縁材料により形成されるハウジング部１３０とを有する。正側ターミナル部１１０および負側ターミナル部１２０は、水平方向に突き出るように設けられるかしめ端子１１２、１２２を有する。かしめ端子１１２、１２２に電子部品２００の足を挿入してかしめることにより、電子部品２００は正側ターミナル部１１０および負側ターミナル部１２０に対して固定される。本例において、正側ターミナル部１１０および負側ターミナル部１２０は、例えば板金等の方法により製造される。   As shown in FIG. 4, the intervention member 100 includes a positive terminal portion 110 and a negative terminal portion 120 formed of a plate-like conductive material such as a stainless steel plate, and a housing portion formed of an insulating material such as plastic. 130. The positive side terminal part 110 and the negative side terminal part 120 have caulking terminals 112 and 122 provided so as to protrude in the horizontal direction. The electronic component 200 is fixed to the positive terminal portion 110 and the negative terminal portion 120 by inserting and crimping the legs of the electronic component 200 into the crimp terminals 112 and 122. In this example, the positive terminal part 110 and the negative terminal part 120 are manufactured by a method such as sheet metal, for example.

ハウジング部１３０は、長手方向の両側および中央部に、切り欠かれるように形成された係合溝１３１、１３２を有する。また、ハウジング部１３０の下面の中央部には、上方に向けて窪んだ凹部１３５を有する。係合溝１３１および係合溝１３２は、水平方向において対称な形状を有する。これらの係合溝１３１、１３２のうち、係合溝１３１は正側ターミナル部１１０の水平方向の両側部と係合し、係合溝１３２は負側ターミナル部１２０の水平方向の両側部と係合する。   The housing part 130 has engagement grooves 131 and 132 formed so as to be cut out on both sides and the center part in the longitudinal direction. Further, a central portion of the lower surface of the housing portion 130 has a concave portion 135 that is recessed upward. The engagement groove 131 and the engagement groove 132 have a symmetrical shape in the horizontal direction. Of these engaging grooves 131, 132, the engaging groove 131 engages with both sides in the horizontal direction of the positive terminal portion 110, and the engaging groove 132 engages with both sides in the horizontal direction of the negative terminal portion 120. Match.

また、ハウジング部１３０の上面には、ロック用突起１３３、１３４が設けられる。ロック用突起１３３は、正側ターミナル部１１０の水平方向に延出するロック用穴１１１と係合し、ロック用突起１３４は、負側ターミナル部１２０の水平方向に延出するロック用穴１２１と係合する。   Further, locking protrusions 133 and 134 are provided on the upper surface of the housing portion 130. The locking protrusion 133 engages with the locking hole 111 extending in the horizontal direction of the positive terminal portion 110, and the locking protrusion 134 is engaged with the locking hole 121 extending in the horizontal direction of the negative terminal portion 120. Engage.

このように、組み立て後の介装部材１００において、正側ターミナル部１１０および負側ターミナル部１２０とハウジング部１３０は、正側ターミナル部１１０および負側ターミナル部１２０側のロック用穴１１１、１２１、ハウジング部１３０側の係合溝１３１、１３２およびロック用突起１３３、１３４などにより互いに固定される。   Thus, in the interposition member 100 after assembly, the positive terminal portion 110 and the negative terminal portion 120 and the housing portion 130 are the locking holes 111 and 121 on the positive terminal portion 110 and the negative terminal portion 120 side, The engaging grooves 131 and 132 on the housing part 130 side and the locking protrusions 133 and 134 are fixed to each other.

また、電子部品２００は、上記のように正側ターミナル部１１０および負側ターミナル部１２０に対して固定される。この状態において、ハウジング部１３０における凹部１３５の両側に正側ターミナル部１１０における鉛直方向に延出する挟持部１１３と、負側ターミナル部１２０における鉛直方向に延出する挟持部１２３とが配される。   Further, the electronic component 200 is fixed to the positive terminal portion 110 and the negative terminal portion 120 as described above. In this state, a sandwiching portion 113 extending in the vertical direction in the positive terminal portion 110 and a sandwiching portion 123 extending in the vertical direction in the negative terminal portion 120 are arranged on both sides of the recess 135 in the housing portion 130. .

このように組み立てられた状態において、正側ターミナル部１１０と負側ターミナル部１２０とは、ハウジング部１３０により互いに絶縁された状態で保持される。したがって、介装部材１００をバスバー２０に取り付けたときにバスバー２０の正側接続部２１側と負側接続部２２側とを誤ってショートさせてしまうことがない。   In the assembled state, the positive terminal portion 110 and the negative terminal portion 120 are held in a state of being insulated from each other by the housing portion 130. Therefore, when the interposition member 100 is attached to the bus bar 20, the positive side connecting portion 21 side and the negative side connecting portion 22 side of the bus bar 20 are not accidentally short-circuited.

組み立てられた介装部材１００をバスバー２０に取り付ける際には、図６に示すように、バスバー２０の前縁側の垂直部分における正側接続部２１を正側ターミナル部１１０の挟持部１１３とハウジング部１３０の前面とで挟持させるとともに、負側接続部２２を負側ターミナル部１２０の挟持部１２３とハウジング部１３０の前面とで挟持させる。これにより、介装部材１００は、バスバー２０に固定される。   When the assembled interposed member 100 is attached to the bus bar 20, as shown in FIG. 6, the positive side connection portion 21 in the vertical portion on the front edge side of the bus bar 20 is connected to the holding portion 113 and the housing portion of the positive side terminal portion 110. The negative connection portion 22 is held between the holding portion 123 of the negative terminal portion 120 and the front surface of the housing portion 130. Thereby, the intervention member 100 is fixed to the bus bar 20.

また、介装部材１００は、正側ターミナル部１１０の挟持部１１３と、負側ターミナル部１２０の挟持部１２３の間に連結部２８が位置するようにバスバー２０に固定される。そして、この状態において、連結部２８の後ろ側には、ハウジング部１３０の凹部１３５が配される。したがって、介装部材１００をバスバー２０に取り付けた後でも、介装部材１００を損傷することなくバスバー２０の前面側から切断具を差し込んで連結部２８を切断することができる。   In addition, the intervention member 100 is fixed to the bus bar 20 so that the connecting portion 28 is located between the holding portion 113 of the positive terminal portion 110 and the holding portion 123 of the negative terminal portion 120. In this state, the recessed portion 135 of the housing portion 130 is disposed behind the connecting portion 28. Therefore, even after the interposition member 100 is attached to the bus bar 20, the connecting portion 28 can be cut by inserting the cutting tool from the front side of the bus bar 20 without damaging the interposition member 100.

図７は、ベース部材３０の中央部を裏面側から見た図である。図７に示すように、ベース部材３０の裏面側には、正側接続部２１および負側接続部２２の一部がベース部材３０を貫通した正側端子２６および負側端子２７を有するコネクタ２９が設けられている。   FIG. 7 is a view of the central portion of the base member 30 as viewed from the back side.
