Description

本発明は、電子部品と電線を収容して該電線を接地する電子部品接続箱が複数積層されて設けられた電子部品接続箱積層体、及びこの電子部品接続箱積層体に前記電子部品と前記電線とが収容されてなる電子部品内蔵ユニットに関するものである。   The present invention provides an electronic component connection box laminate in which a plurality of electronic component connection boxes that house an electronic component and an electric wire and ground the electric wire are provided, and the electronic component and the electronic component in the electronic component connection box laminate. The present invention relates to an electronic component built-in unit that accommodates electric wires.

例えば、自動車等に装備される各種センサ等は、ホーンやワイパモータのような高周波成分を持った雑音源からの電動ノイズや、ネオンサイン等からの外来ノイズや、誘導ノイズ等が電線を伝わって入力されることがあり、これによって誤動作を引き起こしてしまうことがあるという問題が生じていた。   For example, in various sensors equipped in automobiles, electric noise from noise sources with high frequency components such as horns and wiper motors, external noise from neon signs, etc., induction noise, etc. are transmitted via wires. In some cases, this causes a malfunction.

そのため、自動車等に搭載されるワイヤハーネス等においては、そのノイズ対策として、当該ワイヤハーネスを構成するアース用の電線をコンデンサを介して適当な接地部分（例えば車両のボディ等）に接続することが行われている。このようにコンデンサを介して所定の電線を接地するためのコンデンサ内蔵コネクタとしては、例えば、特許文献１に記載されているものが知られている。   Therefore, in a wire harness or the like mounted on an automobile or the like, as a countermeasure against the noise, an earthing wire constituting the wire harness can be connected to an appropriate grounding part (for example, a vehicle body) via a capacitor. Has been done. As a connector with a built-in capacitor for grounding a predetermined electric wire through a capacitor as described above, for example, one described in Patent Document 1 is known.

特許文献１に示すコンデンサ内蔵コネクタは、一対のリード端子がコンデンサ本体から互いに同じ向きに突出した一般的なコンデンサと、このコンデンサの一方のリード端子を接地部分に接続するアース接続導体と、このコンデンサの他方のリード端子を電線側に接続する電線接続導体と、この電線接続導体に接続される電線側端子が取り付けられた電線と、を合成樹脂製のハウジングに収容した構成となっている。
特開２００６−１０００６１号公報 A capacitor built-in connector shown in Patent Document 1 includes a general capacitor in which a pair of lead terminals protrudes from the capacitor body in the same direction, an earth connection conductor that connects one lead terminal of the capacitor to a ground portion, and the capacitor The other lead terminal is connected to the electric wire side, and the electric wire to which the electric wire side terminal connected to the electric wire connection conductor is attached is housed in a synthetic resin housing.

しかしながら、上述した従来のコンデンサ内蔵コネクタは、１回路分のノイズ除去しかできないことから、複数の回路のノイズ除去を行う場合は、回路数分のコンデンサ内蔵コネクタを、接地部分（例えば車両のボディ等）へ一つ一つ取り付けねばならず、この取り付け作業が煩雑なものになってしまうという問題があった。また、複数のコンデンサ内蔵コネクタを取り付けるために大きい取り付けスペースが必要になるという問題があった。なお、このような問題は、コンデンサ内蔵コネクタに限定する問題ではなく、電子部品を収容する電子部品接続箱にも同様に生じる問題である。   However, since the conventional capacitor built-in connector described above can only remove noise for one circuit, when removing noise from a plurality of circuits, connect the connectors with built-in capacitors for the number of circuits to a ground portion (for example, a vehicle body). ) Had to be attached one by one, and there was a problem that this installation work became complicated. In addition, there is a problem that a large mounting space is required to mount a plurality of connectors with built-in capacitors. Such a problem is not limited to the capacitor built-in connector, but also occurs in the electronic component connection box that accommodates the electronic component.

したがって本発明は、複数回路のノイズ除去を行うことができ、取り付けスペースが小さくかつ取り付け作業が容易な電子部品接続箱積層体及び電子部品内蔵ユニットを提供することを目的とする。   Accordingly, an object of the present invention is to provide an electronic component junction box laminate and an electronic component built-in unit that can remove noise from a plurality of circuits, have a small mounting space, and can be easily mounted.

電子部品内蔵ユニット１を組み立てるには、まず、電子部品接続箱２Ａ，２Ｂのケース１１それぞれに部品を組み付けて、それから、ケース１１同士を、電子部品接続箱２Ａのケース１１の底壁２３と、電子部品接続箱２Ｂの接地部材１２Ｂのカバー部１２ｂと、が当接する向きで重ね、係止爪２９と係止穴３０とを互いに係止させることによりケース１１同士を固定する。そして組み立てられた電子部品内蔵ユニット１を相手部材に取り付ける。   In order to assemble the electronic component built-in unit 1, first, the components are assembled in each of the case 11 of the electronic component connection box 2A, 2B, and then the cases 11 are connected to the bottom wall 23 of the case 11 of the electronic component connection box 2A, The cases 11 are fixed together by overlapping the contact portions 12b of the grounding member 12B of the electronic component connection box 2B in contact with each other and locking the locking claws 29 and the locking holes 30 to each other. Then, the assembled electronic component built-in unit 1 is attached to the mating member.

具体的には、コンデンサ３が電子部品収容部２１の開口２１ａから挿入され、電線収容部２２にコンデンサ３の端子３２，３３が突出した状態で電子部品収容部２１に収容される。そして、電線収容部２２にバスバー１４が挿入されてケース１１に固定される。また、係止部材１３が接地部材１２Ａの取付部１２ｇに挿入され、カバー部１２ｂの中央までスライドされることで、接地部材１２Ａに係止される。   Specifically, the capacitor 3 is inserted from the opening 21 a of the electronic component housing portion 21, and is housed in the electronic component housing portion 21 with the terminals 32 and 33 of the capacitor 3 protruding from the wire housing portion 22. Then, the bus bar 14 is inserted into the wire accommodating portion 22 and fixed to the case 11. Further, the locking member 13 is inserted into the attachment portion 12g of the grounding member 12A and is slid to the center of the cover portion 12b, thereby being locked to the grounding member 12A.

そして、接地部材１２Ａ，１２Ｂが、それぞれ電線収容部２２の開口２２ａを塞ぐようにケース１１に近付けられ、係止部１２ｃ，１２ｄと一対の係止部２７とがそれぞれ係止される。また、コンデンサ３の端子３３上には、バスバー１４と接地部材１２Ａ，１２Ｂの接続部１２ａが位置しており、それらが溶接等によって電気的に接続される。   Then, the grounding members 12A and 12B are brought close to the case 11 so as to block the opening 22a of the electric wire housing part 22, and the locking parts 12c and 12d and the pair of locking parts 27 are locked.

By aligning the screw holes and fastening and fixing with the screws, the grounding portion 12f is mechanically fixed to the mating member and electrically connected. That is, it is grounded. Thus, the electronic component built-in unit 1 functions as a noise filter for removing noise from a plurality of circuits.

このように、本発明では、複数の電子部品接続箱２Ａ，２Ｂ同士を積層した状態で相手部材に取り付けることから、電子部品接続箱２Ａ，２Ｂを一つ一つ相手部材に取り付ける必要がなく、そのために、取付作業を容易にすることができる。また、複数の電子部品接続箱２Ａ，２Ｂ同士を積層することで、相手部材への取り付けスペースを小さくすることができる。   Thus, in this invention, since it attaches to a mating member in the state which laminated | stacked several electronic component connection boxes 2A and 2B, it is not necessary to attach electronic component connection box 2A, 2B to a mating member one by one, For this reason, the mounting operation can be facilitated. Moreover, the attachment space to the other member can be made small by laminating | stacking several electronic component connection boxes 2A and 2B.
