　本発明は、開口部が設けられたケースに対して、側方接続型電気部品接続ユニットが端縁部に設けられたプリント基板が収納されてなる電気回路装置に関するものである。 The present invention relates to an electric circuit device in which a printed circuit board in which a side connection type electric component connection unit is provided at an edge portion is accommodated in a case provided with an opening.
　従来から、自動車の電装系の適所には、各種の車載電気機器への電力の分配や制御を行う電気接続箱や制御ユニット等の電気回路装置が設けられている。これらの電気回路装置の中でも特に小型のものとして、例えば、特開２０１１－１４７２６５号公報（特許文献１）に記載のものが知られている。この電気回路装置は、側面に開口部を有する偏平箱体形状のケースと、かかるケース内に収容保持されるプリント基板を含んで構成されており、プリント基板の一方の端縁部には、プリント基板の側方からコネクタやヒューズ等の外部の部品が接続される側方接続型電気部品接続ユニットが設けられている。そして、ケースの開口部からプリント基板の他方の端縁部を挿し入れて、ケースの開口部をプリント基板の一方の端縁部に設けた側方接続型電気部品接続ユニットで覆蓋することにより、ケースの内部にプリント基板が覆蓋状態で収容されるようになっている。要するに、プリント基板の端縁部に設けられた側方接続側部品がケースの開口部を覆うカバー部材としての機能を担うことにより、部品点数の削減や構造の簡素化が図られているのである。 Conventionally, electric circuit devices such as an electric junction box and a control unit for distributing and controlling electric power to various in-vehicle electric devices have been provided at appropriate places in the electric system of automobiles. Among these electric circuit devices, as a particularly small device, for example, a device described in JP 2011-147265 A (Patent Document 1) is known. This electric circuit device includes a case having a flat box shape having an opening on a side surface and a printed circuit board accommodated and held in the case. A printed circuit board is provided on one end edge of the printed circuit board. A side connection type electrical component connection unit to which external components such as connectors and fuses are connected from the side of the substrate is provided. And by inserting the other edge of the printed circuit board from the opening of the case and covering the opening of the case with a side connection type electrical component connection unit provided on one edge of the printed circuit board, A printed circuit board is accommodated inside the case in a cover state. In short, the side connection side component provided at the edge of the printed circuit board serves as a cover member that covers the opening of the case, thereby reducing the number of components and simplifying the structure. .
　ところで、このような構造の電気回路装置では、ケースの開口部に側方接続型電気部品接続ユニットを固定的に取り付けるために、側方接続型電気部品接続ユニットの外周壁部の複数箇所に、ケース固定部を設ける必要がある。一方、側方接続型電気部品接続ユニットには、一端側がプリント基板の導電路に半田付けされる接続端子が収容配置されている。それ故、かかる接続端子のプリント基板への位置決め保持を行うために、側方接続型電気部品接続ユニットのプリント基板側に位置する底壁部には、プリント基板への基板固定部も設ける必要がある。従って、特許文献１の従来構造では、側方接続型電気部品接続ユニットのケース固定部をプリント基板の端縁部よりもケースの開口部側に設ける一方、側方接続型電気部品接続ユニットの基板固定部をプリント基板の端縁部よりも内部側に設ける構造が提案されている。これにより、接続端子の半田付けに際して、側方接続側部品装着部をプリント基板の上方から端縁部に載置しても、ケース固定部がプリント基板と干渉して載置が困難となることが避けられており、接続端子の一端側をスルーホールやパッド部に設置することが、容易且つ確実に行い得るようになっている。 By the way, in the electric circuit device having such a structure, in order to fix the side connection type electrical component connection unit to the opening of the case in a fixed manner, at a plurality of locations on the outer peripheral wall portion of the side connection type electrical component connection unit, It is necessary to provide a case fixing part. On the other hand, in the side connection type electrical component connection unit, a connection terminal whose one end is soldered to the conductive path of the printed circuit board is accommodated. Therefore, in order to position and hold the connection terminals on the printed circuit board, it is necessary to provide a board fixing part to the printed circuit board on the bottom wall part located on the printed circuit board side of the side connection type electrical component connection unit. is there. Therefore, in the conventional structure of Patent Document 1, the case fixing portion of the side connection type electrical component connection unit is provided closer to the opening of the case than the edge of the printed circuit board, while the substrate of the side connection type electrical component connection unit is provided. There has been proposed a structure in which the fixing portion is provided on the inner side of the edge portion of the printed circuit board. As a result, when soldering the connection terminals, even if the side connection side component mounting part is placed on the edge from the top of the printed circuit board, the case fixing part interferes with the printed circuit board, making placement difficult. Therefore, it is possible to easily and surely install one end side of the connection terminal in the through hole or the pad portion.
　ところが、このような特許文献１の構造では、プリント基板の端縁部に設けられた側方接続型電気部品接続ユニットがケースの開口部を覆うカバー部材としての構造が一体的に設けられていることから、部品点数の削減が図られるものの、プリント基板のケース開口部への挿入方向において、ケース固定部と基板固定部を離隔させる必要があり、その離隔距離の分、電気回路装置の大型化が避けられないという問題を内在していた。 However, in such a structure of Patent Document 1, a structure as a cover member in which a side connection type electrical component connection unit provided at an edge of a printed circuit board covers an opening of a case is integrally provided. Therefore, although the number of parts can be reduced, it is necessary to separate the case fixing part and the board fixing part in the insertion direction of the printed circuit board into the case opening, and the size of the electric circuit device is increased by the separation distance. Was inherently inevitable.
　電気回路装置の小型化を図るために、プリント基板のケース開口部への挿入方向でケース固定部と基板固定部の位置を近接又はオーバーラップさせることも考えられるが、そうすると、接続端子の半田付けに際して、自動実装装置により側方接続型電気部品接続ユニットを単にプリント基板の上方から組み付けることが、プリント基板とケース固定部との干渉により困難となり、手作業での組み付けが必要となることから、好ましい対応とは言い難かった。 In order to reduce the size of the electric circuit device, it is conceivable that the position of the case fixing part and the board fixing part are close or overlapped in the direction of insertion into the case opening of the printed circuit board. At the time, it is difficult to assemble the side connection type electrical component connection unit from above the printed circuit board by the automatic mounting device, because it becomes difficult due to interference between the printed circuit board and the case fixing part, and manual assembly is required. It was hard to say that this was a favorable response.

To do. Thus, the front end portions of the upper wall portion 78 and the bottom wall portion 90 of the case 18 are inserted into the guide portions 40 and 52 of the side connection type connector 16, respectively, and engaging protrusions (not shown) of the case 18 are engaged. The portions 88 and 96 are inserted into the engaging grooves 46, 58, 44 and 56 of the side connection type connector 16, respectively. Next, the case 18 is further pushed toward the side connection type connector 16, whereby the case 18 is provided with the guide portions 40 and 52 and the engaging groove portions 46, 58, 44 and 56 provided in the side connection type connector 16. The lock claws 38 and 50 provided in the side connection type connector 16 are locked and engaged with the engagement holes 84 and 84 of the engagement frames 80 and 92 formed in the case 18. A case 18 is fixed to the side connection type connector 16. Thereby, in a state where the printed circuit board 12 is accommodated and held in the case 18, the case 18 and the side connection type connector 16 are assembled to each other to form the electric circuit device 10.
　このような構造とされた本実施形態の電気回路装置１０によれば、側方接続型コネクタ１６の底壁部４８に突設された係合溝部５８からなるケース固定部６０ｃと割りピン６２ｃからなる基板固定部６４ｃが、プリント基板１２の端縁部１４の幅方向で相互に離隔させることにより、ケース固定部６０ｃと基板固定部６４ｃを、プリント基板１２のケース１８への挿入方向で相互に重なり合う位置に設けることができた。これにより、プリント基板１２への挿入方向においてケース固定部６０ｃと基板固定部６４ｃが離隔していた従来構造に比して、かかる挿入方向で電気回路装置１０の小型化を図ることができるのである。しかもケース固定部６０ｃが挿通される切欠部７６ｃがプリント基板１２の端縁部１４に設けられていることから、後述するように、側方接続型コネクタ１６をプリント基板１２に上方から載置する工程の妨げとなることもない。 According to the electric circuit device 10 of the present embodiment having such a structure, the case fixing portion 60c and the split pin 62c formed by the engaging groove portion 58 projecting from the bottom wall portion 48 of the side connection connector 16 are provided. The board fixing part 64c to be separated from each other in the width direction of the end edge part 14 of the printed circuit board 12, and thereby the case fixing part 60c and the board fixing part 64c are mutually connected in the insertion direction of the printed circuit board 12 into the case 18. It could be provided at the overlapping position. Thereby, compared with the conventional structure in which the case fixing part 60c and the board fixing part 64c are separated from each other in the insertion direction to the printed circuit board 12, the electric circuit device 10 can be downsized in the insertion direction. . Moreover, since the notch portion 76c through which the case fixing portion 60c is inserted is provided in the end edge portion 14 of the printed circuit board 12, the side connection type connector 16 is placed on the printed circuit board 12 from above as will be described later.

　また、ケース固定部６０ｃと基板固定部６４ｃがプリント基板１２の端縁部１４の中央部分に配設されていることから、プリント基板１２の端縁部１４の両端部の空き領域を利用して、プリント基板１２のケース１８への挿入方向で相互に離隔した位置にさらにケース固定部６０ａ，６０ｂと基板固定部６４ａ，６４ｂを設けることができる。一組のケース固定部６０ｃと基板固定部６４ｃがプリント基板１２の端縁部１４の幅方向で相互に離隔していることに加えて、さらにプリント基板１２の端縁部１４の両端側にケース固定部６０ａ，６０ｂと基板固定部６４ａ，６４ｂを設けることにより、側方接続型コネクタ１６の左右方向のねじれ荷重に対して、プリント基板１２及びケース１８に対する側方接続型コネクタ１６の固定力が安定して発揮される。さらに、ケース固定部６０ａ，６０ｂと基板固定部６４ａ，６４ｂが、プリント基板１２のケース１８への挿入方向で相互に離隔していることから、側方接続型コネクタ１６の上下方向のねじれ荷重に対しても、プリント基板１２およびケース１８に対する側方接続型コネクタ１６の固定力が一層安定して発揮されるのである。 In addition, since the case fixing part 60c and the board fixing part 64c are disposed in the central portion of the edge part 14 of the printed circuit board 12, the empty areas at both ends of the edge part 14 of the printed circuit board 12 are used. Case fixing portions 60a and 60b and substrate fixing portions 64a and 64b can be further provided at positions separated from each other in the insertion direction of the printed circuit board 12 into the case 18. In addition to the pair of case fixing portions 60c and the substrate fixing portion 64c being separated from each other in the width direction of the edge portion 14 of the printed circuit board 12, a case is further provided on both ends of the edge portion 14 of the printed circuit board 12. By providing the fixing portions 60 a and 60 b and the board fixing portions 64 a and 64 b, the fixing force of the side connection type connector 16 to the printed circuit board 12 and the case 18 against the torsional load in the lateral direction of the side connection type connector 16 is increased. It is demonstrated stably. Further, since the case fixing portions 60a and 60b and the board fixing portions 64a and 64b are separated from each other in the insertion direction of the printed circuit board 12 into the case 18, the lateral connection type connector 16 is subjected to a torsional load in the vertical direction. On the other hand, the fixing force of the side connection type connector 16 with respect to the printed circuit board 12 and the case 18 is more stably exhibited.
　加えて、プリント基板１２の端縁部１４には、ケース固定部６０ａ，６０ｂ，６０ｃがそれぞれ挿通配置される切欠部７６ａ，７６ｂ，７６ｃが形成されている。それ故、側方接続型コネクタ１６をプリント基板１２に半田付けする際に、側方接続型コネクタ１６をプリント基板１２の上方から自動実装装置等により組み付けることができる。すなわち、側方接続型コネクタ１６をプリント基板１２に組み付ける際に側方接続型コネクタ１６のケース固定部６０ａ，６０ｂ，６０ｃに当たるプリント基板１２の部位に切欠部７６ａ，７６ｂ，７６ｃが形成されていることから、組み付けの際にケース固定部６０ａ，６０ｂ，６０ｃがプリント基板１２に干渉することなく装着することができ、自動実装等による組み付け容易化・効率化等を確実に達成することができる。 In addition, notches 76a, 76b, and 76c into which the case fixing portions 60a, 60b, and 60c are respectively inserted are formed in the edge portion 14 of the printed circuit board 12. Therefore, when the side connection type connector 16 is soldered to the printed circuit board 12, the side connection type connector 16 can be assembled from above the printed circuit board 12 by an automatic mounting apparatus or the like. That is, when the side connection type connector 16 is assembled to the printed circuit board 12, notches 76a, 76b, and 76c are formed at portions of the printed circuit board 12 that correspond to the case fixing portions 60a, 60b, and 60c of the side connection type connector 16. Therefore, the case fixing portions 60a, 60b, 60c can be mounted without interfering with the printed circuit board 12 at the time of assembly, and it is possible to reliably achieve ease of assembly / efficiency by automatic mounting or the like.
　以上、本発明の実施形態について詳述してきたが、本発明はその具体的な記載によって限定されない。例えば、本実施形態では、ケース固定部６０ａ，６０ｂ，６０ｃと基板固定部６４ａ，６４ｂ，６４ｃが設けられていたが、ケース固定部６０ｃと基板固定部６４ｃ以外は任意に選択可能である。すなわち、少なくともケース固定部６０ｃと基板固定部６４ｃが設けられていればよい。 As mentioned above, although embodiment of this invention has been explained in full detail, this invention is not limited by the specific description.
