Description

本発明は、電子部品ユニット及び照明ユニットに係り、具体的には樹脂製のハウジング内に固定された回路導体に装着される電子部品又は電子部品の1つである発光素子の装着部の構造に関する。   The present invention relates to an electronic component unit and a lighting unit, and more particularly, to an electronic component mounted on a circuit conductor fixed in a resin housing or a structure of a mounting portion of a light-emitting element that is one of the electronic components. .

樹脂製のハウジング内に収容された回路導体(バスバーとも称する。)に、1又は複数の電子部品を接続して電子部品ユニットを構成している(例えば、特許文献1等)。このような電子部品ユニットにおいては、ハウジング内に収容される回路導体と電子部品との接続及び配置を工夫して複数の電子部品を高密度に収容することができるので、ハウジング内のスペースの無駄を省いて小型化することができる。   An electronic component unit is configured by connecting one or more electronic components to a circuit conductor (also referred to as a bus bar) housed in a resin housing (for example, Patent Document 1). In such an electronic component unit, a plurality of electronic components can be accommodated at a high density by devising connection and arrangement of circuit conductors accommodated in the housing and the electronic components, so that the space in the housing is wasted. It is possible to reduce the size by omitting.

例えば、特許文献1等の電子部品ユニットは、電気回路を構成する回路導体と、その回路導体に電気的に接続される複数の電子部品と、その回路導体と複数の電子部品とを収容する樹脂製のハウジングとを備えて構成される。回路導体は、導体板に切り込みを入れて二股状に形成された端子部を備え、この二股状の端子部に電子部品の端子部を挿入して電子部品を保持させるとともに、電子部品と回路導体とを電気的に接続するようになっている。   For example, an electronic component unit disclosed in Patent Document 1 includes a circuit conductor constituting an electric circuit, a plurality of electronic components electrically connected to the circuit conductor, and a resin that accommodates the circuit conductor and the plurality of electronic components. And a housing made of metal. The circuit conductor includes a terminal portion formed in a forked shape by cutting a conductor plate. The terminal portion of the electronic component is inserted into the forked terminal portion to hold the electronic component, and the electronic component and the circuit conductor. Are electrically connected to each other.

また、特許文献1には、一対の回路導体を構成する導体板の長手方向の先端から切り込みを入れて、それぞれ支持部と接触端子とから形成された二股状の電子部品装着部を備え、それら一対の電子部品装着部を並べてハウジングに収容した電子部品ユニットが記載されている。これにより、一対の電子部品装着部の二股状の支持部と接触端子との対向空間に電子部品を挿入して挟持させることにより、電子部品を一対の回路導体間に電気的に接続することができる。つまり、電子部品の一方の面(例えば、裏面)に露出して形成された一対の端子をそれぞれの回路導体の接触端子に接触させ、他方の面(例えば、表面)をそれぞれの回路導体の支持部に当接させて、一対の回路導体間に電子部品を渡して電気的に接続するようになっている。   Patent Document 1 also includes a bifurcated electronic component mounting portion formed by cutting from the longitudinal ends of the conductor plates constituting the pair of circuit conductors, each formed from a support portion and a contact terminal. An electronic component unit in which a pair of electronic component mounting portions are arranged and accommodated in a housing is described. Accordingly, the electronic component can be electrically connected between the pair of circuit conductors by inserting and sandwiching the electronic component in the space between the forked support portion of the pair of electronic component mounting portions and the contact terminal. it can. That is, a pair of terminals formed exposed on one surface (for example, the back surface) of the electronic component are brought into contact with the contact terminals of each circuit conductor, and the other surface (for example, the front surface) is supported by each circuit conductor. The electronic component is passed between the pair of circuit conductors so as to be electrically connected to each other.

ところで、特許文献1に記載の電子部品装着部の支持部は、長手方向に伸延する導体板の両側を接触端子側に折り曲げて形成されているから、電子部品が当接する支持面は導体板の両側に折り曲げられた側壁の縁面になる。しかし、側壁の縁面は直状に伸延されているから、直状の側壁の縁面に電子部品の一面を位置合わせしながら、挿入しなければならない。つまり、支持部の両側壁の縁面と接触端子との小さい隙間を狙って、小さな電子部品の位置を調節しながら挿入しなければならないから、組み付け作業に時間がかかるという問題がある。   By the way, since the support part of the electronic component mounting part described in Patent Document 1 is formed by bending both sides of the conductor plate extending in the longitudinal direction to the contact terminal side, the support surface with which the electronic component abuts is the conductor plate. It becomes the edge surface of the side wall bent on both sides. However, since the edge surface of the side wall is extended in a straight shape, it must be inserted while aligning one surface of the electronic component with the edge surface of the straight side wall. That is, there is a problem that it takes time to assemble because it must be inserted while adjusting the position of the small electronic component aiming at a small gap between the edge surface of the both side walls of the support portion and the contact terminal.

本発明が解決しようとする課題は、回路導体に二股状に形成された電子部品の装着部に電子部品を挿入する作業を簡単化して、電子部品ユニット及び照明ユニットの組付け作業時間を短縮することにある。   The problem to be solved by the present invention is to simplify the work of inserting an electronic component into a mounting portion of an electronic component formed in a bifurcated shape on a circuit conductor, and shorten the assembly work time of the electronic component unit and the lighting unit. There is.

上記の課題を解決するため、本発明の電子部品ユニットは、電気回路を構成する回路導体と、該回路導体に電気的に接続される複数の電子部品と、前記回路導体と前記電子部品とを収容する樹脂製のハウジングとを備え、前記回路導体は、導体板に切り込みを入れて二股状に形成された1又は複数の端子部と、導体板の長手方向の先端から切り込みを入れて二股状に形成された支持部と接触端子とからなる電子部品装着部とを有し、前記電子部品装着部の前記支持部と前記接触端子との対向空間に前記電子部品を挿入して挟持させて形成する。特に、前記支持部は導体板を折り曲げて前記電子部品が当接される支持平面を有して形成され、前記接触端子は前記支持平面に対向させて前記電子部品の露出端子に押接される弾性を有して形成され、前記接触端子の先端は先細り状に形成され、前記支持部の先端の導体板は対向する前記接触端子から離れる方向に開いた形状に形成されてなることを特徴とする。   In order to solve the above problems, an electronic component unit according to the present invention includes a circuit conductor constituting an electric circuit, a plurality of electronic components electrically connected to the circuit conductor, the circuit conductor and the electronic component. A housing made of resin, and the circuit conductor has one or a plurality of terminal portions formed in a forked shape by incising the conductor plate, and a forked shape by making a notch from the longitudinal end of the conductor plate. An electronic component mounting portion comprising a support portion and a contact terminal formed on the electronic component, and the electronic component is inserted and sandwiched in a space between the support portion of the electronic component mounting portion and the contact terminal. To do. In particular, the support portion is formed to have a support plane on which the electronic component is abutted by bending a conductor plate, and the contact terminal is pressed against the exposed terminal of the electronic component so as to face the support plane. The contact terminal is formed with elasticity, the tip of the contact terminal is formed in a tapered shape, and the conductive plate at the tip of the support part is formed in a shape opened in a direction away from the opposing contact terminal. To do.

このように、電子部品装着部を構成する二股状の支持部と接触端子の形状を、接触端子の先端は先細り状に形成し、支持部の先端の導体板は対向する接触端子から離れる方向に開いた形状にしたことから、支持部と接触端子との先端の隙間が広くなるので、隙間に挿入する電子部品の位置合わせに格別な調節が不要になる。その結果、電子部品の組み付け作業を簡単化でき、作業時間を短縮できるという効果がある。   In this way, the shape of the bifurcated support portion and the contact terminal constituting the electronic component mounting portion is formed such that the tip of the contact terminal is tapered, and the conductor plate at the tip of the support portion is away from the opposing contact terminal. Since the opening shape is wide, a gap at the tip of the support portion and the contact terminal is widened, so that no special adjustment is required for alignment of the electronic component inserted into the gap. As a result, it is possible to simplify the assembling work of the electronic parts and shorten the working time.

本発明によれば、回路導体に二股状に形成された電子部品の装着部に電子部品を挿入する作業を簡単化できるから、電子部品ユニット及び照明ユニットの組付け作業時間を短縮できる。   According to the present invention, it is possible to simplify the operation of inserting the electronic component into the mounting portion of the electronic component formed in a bifurcated shape on the circuit conductor, so that the time for assembling the electronic component unit and the lighting unit can be shortened.

As shown in FIG. 1, each circuit conductor 2a, 2b is formed into a desired shape by cutting and bending a flat conductor plate. As can be seen from the figure, the circuit conductors 2a and 2b are formed substantially symmetrically with respect to the longitudinal direction, and are arranged in the accommodation space formed in the housing 7 so as to be accommodated from the lower surface side in the figure. . For example, each of the circuit conductors 2a and 2b is formed in a bifurcated shape with a plurality of terminal portions 11 and 12 formed in a forked shape by cutting the conductive plate and a longitudinal end of the conductive plate.

And the surface which opposes the support part 12b of the contact terminal 12a is formed in protrusion shape, and the surface which opposes the contact terminal 12a of the support part 12b is formed in planar shape. Accordingly, when the resistor 5 formed in a thin rectangular parallelepiped is inserted into the forked shape of the pair of terminal portions 12, one surface of the resistor 5 is brought into contact with the pair of support portions 12b and the resistor 5 The pair of terminals formed in the contact is held and electrically connected to the corresponding pair of contact terminals 12a.

As shown in FIG. 1, the electronic component mounting portion 13 of this embodiment is formed with a pair of circuit conductors 2a and 2b. Since the circuit conductors 2a and 2b are formed almost symmetrically with respect to the longitudinal direction as described above, the electronic component mounting portion 13 formed on the circuit conductor 2a will be described as an example. The electronic component mounting portion 13 formed on the circuit conductor 2a side includes a support portion 13a and a contact terminal 13b that are formed in a forked shape by cutting in the longitudinal direction of the conductor plate. The support portion 13a is formed to have a support plane on which the light emitting diode 3 abuts by bending the outer wall in the longitudinal direction of the conductor plate (the wall on the opposite side of the circuit conductor 2b) into an L shape inside. Yes. The tip of the conductor plate on the support plane protrudes beyond the tip of the wall of the support portion 13a, and the tip of the conductor plate is formed in a shape that opens in a direction away from the opposing contact terminal 13b (downward in the figure). .

The electronic component mounting portion 14 includes a support portion 14a and a contact terminal 14b that are formed in a forked shape by cutting in the longitudinal direction of the conductor plate. The support portion 14 a is formed by extending straight in the longitudinal direction of the conductor plate, and the lower surface of the straight portion is formed on a support plane in contact with the Zener diode 4.

Similarly, the Zener diode 4 is inserted into the facing space between the support portion 14a and the contact terminal 14b of the pair of electronic component mounting portions 14 of the circuit conductor 2 accommodated in the housing 7 through the opening 16 formed in the housing 7. By doing so, the Zener diode 4 can be electrically connected to the pair of circuit conductors 2a and 2b. Further, by storing the resistors 5 and 6 formed in the thin rectangular parallelepiped into the housing 7 through the openings 17 and 18, the resistors 5 and 6 are inserted and connected in series to the circuit conductors 2a and 2b, respectively. . That is, as will be described later, the circuit conductors of the bent portions of the pair of terminal portions 12 formed by bending the circuit conductors 2a and 2b are cut out, and the terminal portions 12-1 connected to the terminal portions 11 and the electronic components are mounted.

一方、照明ユニット1の外部端子である一対の端子部11に接続される電線31は、樹脂製の外部配線ホルダー8に組み付けられ、ハウジング7の端面開口から一対の圧接刃12a、b間に挿入されるようになっている。つまり、外部配線ホルダー8は、ハウジング7に挿入される直方体状のブロック30の3面に沿って形成された配索溝内に電線31を巻き付けて形成されている。また、ブロック30の左右の側壁にそれぞれ係止突起32が設けられ、左右の側壁と電線31の配索溝との間にハウジング7の側壁が挿入可能なすき間が形成されている。これにより、外部配線ホルダー8をハウジング7の端面開口からハウジング7内に挿入することにより、電線31が一対の圧接刃12a、b間に挿入され、芯線が溝部11cに圧入されて電気的に接続されるようになっている。このとき、ブロック30の係止突起34がカバー9の側面に形成された開口26に嵌合されて、ハウジング7及びカバー9に固定され、図2(a)、(b)に示す照明器具を形成することができる。   On the other hand, the electric wires 31 connected to the pair of terminal portions 11 that are external terminals of the lighting unit 1 are assembled to the resin-made external wiring holder 8 and inserted between the pair of press contact blades 12a and 12b from the end face opening of the housing 7. It has come to be. That is, the external wiring holder 8 is formed by winding the electric wire 31 in the routing groove formed along the three surfaces of the rectangular parallelepiped block 30 inserted into the housing 7. Further, locking projections 32 are provided on the left and right side walls of the block 30, respectively, and a gap into which the side wall of the housing 7 can be inserted is formed between the left and right side walls and the wiring groove of the electric wire 31. Thereby, by inserting the external wiring holder 8 into the housing 7 from the end face opening of the housing 7, the electric wire 31 is inserted between the pair of press contact blades 12a and 12b, and the core wire is press-fitted into the groove portion 11c to be electrically connected. It has come to be. At this time, the locking projection 34 of the block 30 is fitted into the opening 26 formed on the side surface of the cover 9 and is fixed to the housing 7 and the cover 9, and the lighting apparatus shown in FIGS. Can be formed.

このように、本実施例は、特に、電子部品装着部13を構成する二股状の支持部13aと接触端子13bの形状を、接触端子13bの先端は先細り状に、あるいは接触端子13bの支持部13aに対向する面を突状にして形成し、支持部13aの先端の導体板を対向する接触端子13bから離れる方向に開いた形状に曲げて挿入ガイドを形成したことを特徴とする。これにより、支持部13aと接触端子13bとの先端の隙間が広くなるので、隙間に挿入する薄型直方体の発光ダイオード3の挿入時の位置合わせに格別な調節が不要になる。その結果、電子部品の1つである発光ダイオード3の組み付け作業を簡単化でき、作業時間を短縮できるという効果がある。   As described above, in this embodiment, the shape of the bifurcated support portion 13a and the contact terminal 13b constituting the electronic component mounting portion 13 is particularly determined, the tip of the contact terminal 13b is tapered, or the support portion of the contact terminal 13b. The insertion guide is formed by projecting the surface facing 13a into a protruding shape, and bending the conductor plate at the tip of the support portion 13a into a shape that opens away from the facing contact terminal 13b. As a result, the gap between the tips of the support portion 13a and the contact terminal 13b is widened, so that no special adjustment is required for alignment when the light-emitting diode 3 is inserted into the gap. As a result, it is possible to simplify the assembling work of the light emitting diode 3 which is one of the electronic components, and to shorten the working time.

本実施例の支持部13aの先端の導体板を曲げて挿入ガイドを形成する方法は、周知の技術により形成することができる。しかし、図4に示すように、回路導体2aをプレス加工により形成する際に、同時に支持部13aの先端の導体板を曲げて挿入ガイドを形成することが望ましい。すなわち、回路導体2aをプレス加工等により形成する場合、製造効率を向上させるために、図4(a)に示すように、導体板にキャリア41と称される部分を残して複数の回路導体2aを所望の形状に切断及びプレス加工した後、キャリア41と各回路導体2aとの連結部分43を切断して、各回路導体2aを切り離すようにしている。そこで、図4(b)に示すように、ダイス42の上にキャリア41を載置して連結部分43の切断位置をダイス42の角部に合わせて固定し、パンチ44を図示矢印45方向に打ち抜いて連結部分43を切断する。これにより、図4(c)に示すように、連結部分43の切断部に打ち抜きダレ46が形成される。この打ち抜きダレ46が、接触端子13bから離れる方向に開いた形状の挿入ガイド部47になる。回路導体2bについても、同様に形成することにより、接触端子13bから離れる方向に開いた形状の挿入ガイド部47を形成することができる。   The method for forming the insertion guide by bending the conductor plate at the tip of the support portion 13a of this embodiment can be formed by a known technique. However, as shown in FIG. 4, when the circuit conductor 2a is formed by pressing, it is desirable to simultaneously form the insertion guide by bending the conductor plate at the tip of the support portion 13a. That is, when the circuit conductor 2a is formed by press working or the like, in order to improve manufacturing efficiency, as shown in FIG. 4 (a), a plurality of circuit conductors 2a are left leaving a portion called a carrier 41 on the conductor plate. After being cut and pressed into a desired shape, the connecting portion 43 between the carrier 41 and each circuit conductor 2a is cut to separate each circuit conductor 2a. Therefore, as shown in FIG. 4 (b), the carrier 41 is placed on the die 42, the cutting position of the connecting portion 43 is fixed to the corner of the die 42, and the punch 44 is moved in the direction of the arrow 45 shown in the figure. The connecting portion 43 is cut by punching. Thereby, as shown in FIG. 4C, a punching sag 46 is formed at the cut portion of the connecting portion 43. This punching sag 46 becomes an insertion guide portion 47 having a shape opened in a direction away from the contact terminal 13b. By forming the circuit conductor 2b in the same manner, it is possible to form the insertion guide portion 47 having a shape opened in a direction away from the contact terminal 13b.

図5(b)に、図5(a)に示した照明ユニット1の平面図の線Vb−Vbにおける断面図を示す。図示のように、支持部13aの先端に接触端子13bから離れる方向に開いた形状の挿入ガイド部47が形成されている。なお、前述したように、回路導体2aの一対の端子部12―1、12―2は、ハウジング7に収容されるまでは、図4(a)に示す連結部49により一体に形成されているが、ハウジング7に収容した後、図4(c)の符号50で示したように、連結部49がカットされて、端子部11側と電子部品装着部12,13側が切り離されている。   FIG. 5B is a cross-sectional view taken along line Vb-Vb in the plan view of the illumination unit 1 shown in FIG. As illustrated, an insertion guide portion 47 having a shape opened in a direction away from the contact terminal 13b is formed at the tip of the support portion 13a. As described above, the pair of terminal portions 12-1 and 12-2 of the circuit conductor 2a are integrally formed by the connecting portion 49 shown in FIG. However, after accommodating in the housing 7, as shown by the code | symbol 50 of FIG.4 (c), the connection part 49 is cut and the terminal part 11 side and the electronic component mounting parts 12 and 13 side are cut away.

本実施例では、電子部品装着部13に装着される電子部品として薄型の直方体に形成された発光ダイオード(発光素子)3を例に説明したが、発光ダイオードに限らず、他の電子部品であってもよいことは言うまでもない。また、本実施例の発光ダイオード3、ツェナーダイオード4、抵抗5,6のように、薄型直方体状に形成された電子部品を収容する電子部品ユニットに適用することが好ましいが、これに限られるものではない。   In the present embodiment, the light emitting diode (light emitting element) 3 formed in a thin rectangular parallelepiped has been described as an example of the electronic component to be mounted on the electronic component mounting portion 13, but the present invention is not limited to the light emitting diode but may be other electronic components. Needless to say. In addition, the present invention is preferably applied to an electronic component unit that houses electronic components formed in a thin rectangular parallelepiped shape, such as the light-emitting diode 3, the Zener diode 4, and the resistors 5 and 6, but is not limited thereto. is not.
