　本発明は、車載用の電気接続箱に関し、詳しくは、自動車に搭載した電気接続箱内に無線受信機能を備えたものである。 The present invention relates to an on-vehicle electrical junction box, and more specifically, an electrical junction box mounted on an automobile has a wireless reception function.
　近時、自動車のドアの解錠および施錠を、キー穴にキーを差し込むことなく行えるリモートキーレスエントリシステムが提供されている。
　該システムは、乗員が携帯する送信用のリモートキーや送受信用のスマートキーを用い、これらキーから送信する信号を無線受信機で受信し、受信した信号を無線受信機に接続したワイヤハーネスを介して、ドアロック制御部を含むボディ用電子制御ユニットに送信し、該ボディ用電子制御ユニットでドアロック機構を自動制御して、ドアの解錠および施錠を行っている。
　あるいは、ワイヤハーネスによる接続を無くす場合には、図１２に示すように、無線受信機１００のケース内部にドアロック用電子制御基板１０１および、該ドアロック用電子制御基板１０１に接続したアンテナ１０２を収容し、該無線受信機１００を電気接続箱１０３上に搭載し、コネクタ接続している。 Recently, there has been provided a remote keyless entry system that can unlock and lock an automobile door without inserting a key into a keyhole.
The system uses a remote key for transmission carried by an occupant and a smart key for transmission / reception, receives a signal transmitted from these keys with a wireless receiver, and connects the received signal to a wireless receiver via a wire harness. The door electronic control unit including the door lock control unit transmits the information to the door, and the electronic control unit for the body automatically controls the door lock mechanism to unlock and lock the door.
Alternatively, when the connection by the wire harness is to be eliminated, as shown in FIG. 12, the door lock electronic control board 101 and the antenna 102 connected to the door lock electronic control board 101 are provided inside the case of the wireless receiver 100. The wireless receiver 100 is mounted on the electrical connection box 103 and connected by a connector.
　また、アンテナを備えた無線受信機能を機能収容部（電気接続箱に相当する）内に収容したものとして、特開２００１－３１５５９１号公報（特許文献１）が提供されている。
　該特許文献１に記載の機器収容部２００は、図１３（Ａ）に示すように、所謂、電気接続箱に相当し、ワイヤハーネスと接続されるバスバーやリレー、ヒューズ、ヒュージブルリンク等が収容されている。かつ、機器収容部２００内に、図１３（Ｂ）に示すように統合ＥＣＵ２０１が収容され、統合ＥＣＵ２０１は中央回路基板２０２上に配置し、該中央回路基板２０２の一辺の周縁の一側部に、キーレススイッチ切換信号検出用のキーレスアンテナ２０３が配置されている。このキーレスアンテナ２０３を用いてドアロック状態を判断する、と記載されている。
　前記キーレスアンテナ２０３については詳細な記載は無いが、図示から判断すると、中央回路基板の一辺の側端縁に沿った直線状の金属板と認められる。 Japanese Patent Laid-Open No. 2001-315591 (Patent Document 1) is provided as a wireless receiving function including an antenna housed in a function housing portion (corresponding to an electrical junction box).
As shown in FIG. 13A, the device accommodating portion 200 described in Patent Document 1 corresponds to a so-called electrical connection box, and accommodates bus bars, relays, fuses, fusible links, and the like connected to the wire harness. Has been. Further, as shown in FIG. 13B, the integrated ECU 201 is accommodated in the device accommodating portion 200, and the integrated ECU 201 is disposed on the central circuit board 202 and is disposed on one side of the peripheral edge of the central circuit board 202. A keyless antenna 203 for detecting a keyless switch switching signal is arranged. The keyless antenna 203 is used to determine the door lock state.
Although the keyless antenna 203 is not described in detail, it is recognized as a straight metal plate along the side edge of one side of the central circuit board when judged from the illustration.
特開２００１－３１５５９１号公報JP 2001-315591 A
　特許文献１の電気接続箱からなる機能収容部２００は、その内部にドアロック制御部を有するボディ用電子制御部を含む統合ＥＣＵを収容し、かつ、該統合ＥＣＵの基板の周縁にキーレアンテナ２０３を配置している。よって、従来のアンテナを備えた無線受信機とワイヤハーネスやコネクタを介してドアロック用電子制御ユニットとを接続する必要はない。 A function storage unit 200 including an electrical junction box of Patent Document 1 stores an integrated ECU including a body electronic control unit having a door lock control unit therein, and a keel antenna 203 on the periphery of the substrate of the integrated ECU. Is arranged. Therefore, there is no need to connect a radio receiver equipped with a conventional antenna and a door lock electronic control unit via a wire harness or a connector.
　しかしながら、特許文献１のキーレスアンテナ２０３は、電気接続箱の一側部に収容した統合ＥＣＵ２０１の中央回路基板２０２の一辺の一側部に配置されているだけであるため、その長さは短く、リモートキーやスマートキーからの送信信号を受信するのに十分な長さとなっていないと認められる。即ち、キーレスアンテナ２０３の長さＬを、受信電波の波長λの好ましくは、約λ／２以上、少なくともλ／４以上（約２０～２５ｃｍ）は必要である。よって、図１３（Ｂ）のキーレスアンテナ２０３の長さが２０～２５ｃｍとすると、電気接続箱の全体が非常に大型化（全長が約１００ｃｍ）することとなり、搭載スペースが自動車に搭載できる電気接続箱としては不適なものとなる。 However, since the keyless antenna 203 of Patent Document 1 is only arranged on one side of one side of the central circuit board 202 of the integrated ECU 201 housed in one side of the electrical junction box, its length is short, It is recognized that it is not long enough to receive the transmission signal from the remote key or smart key. That is, the length L of the keyless antenna 203 is preferably about λ / 2 or more, and at least λ / 4 or more (about 20 to 25 cm) of the wavelength λ of the received radio wave. Therefore, if the length of the keyless antenna 203 in FIG. 13B is 20 to 25 cm, the entire electrical junction box becomes very large (the total length is about 100 cm), and the electrical connection that allows the mounting space to be mounted on an automobile. It becomes unsuitable as a box.
　本発明は前記問題に鑑みてなされたもので、電気接続箱を大型化することなく、該電気接続箱内に収容するアンテナの長さを、アンテナ利得が得られる長さと出来るようにすることを課題としている。 The present invention has been made in view of the above problems, and it is possible to make the length of an antenna accommodated in the electrical junction box as long as an antenna gain can be obtained without increasing the size of the electrical junction box. It is an issue.
　前記課題を解決するため、本発明は、車載用の電気接続箱のケース内部に、無線受信回路を備えた基板と、該基板の無線受信回路と一端を接続してケース内部に突出したアンテナを備え、
　前記アンテナは前記無線受信回路に一端を接続する金属棒、または前記基板の下部あるいは上部に配置した絶縁板上に固定しているバスバーからなり、該バスバーの一端側を前記プリント基板側へ屈曲させ、その先端を前記無線受信回路に直接に接続し、または前記バスバーの一端に中継用金属棒を接続し、該中継用金属棒を前記無線受信回路に接続しており、
　前記金属棒またはバスバーからなるアンテナを屈曲させて、前記ケースの外周壁の内面に沿って配置していることを特徴とする車載用の電気接続箱を提供している。 In order to solve the above-described problems, the present invention provides a board provided with a radio reception circuit inside a case of an in-vehicle electrical junction box, and an antenna projecting into the case by connecting one end of the board to the radio reception circuit of the board. Prepared,
The antenna is composed of a metal bar connecting one end to the wireless receiving circuit or a bus bar fixed on an insulating plate disposed at the lower or upper part of the substrate, and the one end of the bus bar is bent toward the printed circuit board. , The tip is directly connected to the wireless reception circuit, or a relay metal rod is connected to one end of the bus bar, and the relay metal rod is connected to the wireless reception circuit,
An in-vehicle electrical junction box is provided, wherein an antenna made of the metal bar or bus bar is bent and arranged along the inner surface of the outer peripheral wall of the case.
　前記アンテナは前記無線受信回路と接続する部分は前記ケースの隅部に垂直方向に配置し、該垂直方向の下端を屈曲して水平方向に延在している。
　前記のように、無線受信回路と接続させて垂直方向に配置するアンテナ部分をケースの隅部に位置させると水平方向の延在部の長さを長くでき、アンテナの屈曲部分を減少することができる。 A portion of the antenna connected to the radio receiving circuit is arranged in a vertical direction at a corner of the case, and a lower end in the vertical direction is bent to extend in the horizontal direction.
As described above, when the antenna portion that is connected to the radio receiving circuit and is arranged in the vertical direction is positioned at the corner of the case, the length of the horizontal extension portion can be increased, and the bent portion of the antenna can be reduced. it can.
　本発明では、電気接続箱に収容する電子制御用の基板の側縁の一部にアンテナを配置するのではなく、該基板の無線受信回路に一端を接続した金属棒またはバスバーでアンテナを形成し、電気接続箱のケース外周壁の内面に沿って設けてアンテナを配置し、アンテナ長さをアンテナ利得が得られる長さとしている。
　かつ、ケースの外周壁の内面に沿って位置はデッドスペースとなっている場合が多く、かつ、ケースの外周壁の内面に沿ってアンテナを配置できるスペースを設けるだけであるため、電気接続箱の外形は殆ど増加せず、電気接続箱が大型化しない。
　さらに、アンテナをケースの外周壁の内面に沿って配置すると、性能設計上、リレー、ヒューズ、バスバー等の搭載部品と距離をあけることが必要となった時、ケースのサイズの増大を押さえ、より小型に設計することができる。 In the present invention, the antenna is not formed on a part of the side edge of the electronic control board accommodated in the electrical junction box, but is formed by a metal rod or bus bar having one end connected to the radio reception circuit of the board. The antenna is arranged along the inner surface of the outer peripheral wall of the case of the electrical junction box, and the antenna length is set to a length that can provide the antenna gain.
In addition, the position along the inner surface of the outer peripheral wall of the case is often a dead space, and only the space for placing the antenna along the inner surface of the outer peripheral wall of the case is provided. The outer shape hardly increases and the electric junction box does not increase in size.
Furthermore, if the antenna is placed along the inner surface of the outer peripheral wall of the case, when it is necessary to keep a distance from the mounted components such as relays, fuses, busbars, etc. in terms of performance design, the increase in the size of the case is suppressed. It can be designed to be small.
　本発明の無線受信回路を設けた基板およびアンテナを備えた電気接続箱は、自動車に搭載されるジャンクションボックスとしていることが好ましい。
　ジャンクションボックスは、自動車に搭載される電装品に対する電源分配を行い、各電装品に接続する分岐回路を設けているものであり、自動車に搭載される電気接続箱の中で最も大型の電気接続箱となっている。
　よって、この大型の電気接続箱からなるジャンクションボックスのケースの外周縁の長さも大きく、ジャンクションボックスのケース外周縁に沿ってアンテナを収容すると、アンテナを十分な長さとすることができると共に、該アンテナの直線部の長さを大とでき、アンテナ利得を改善することができる。 The electrical connection box provided with the substrate and the antenna provided with the wireless reception circuit of the present invention is preferably a junction box mounted on an automobile.
The junction box distributes power to the electrical components mounted on the automobile and has a branch circuit that connects to each electrical component. The junction box is the largest electrical junction box installed on the automobile. It has become.
Therefore, the length of the outer peripheral edge of the case of the junction box made of this large electric junction box is also large, and when the antenna is accommodated along the outer peripheral edge of the junction box, the antenna can be made sufficiently long. The length of the linear portion can be increased, and the antenna gain can be improved.
　前記金属棒からなるアンテナの水平方向部は、前記ケースの外周壁の内面に沿って設けた溝状のアンテナ載置部に載置して配置し、または前記外周壁の内面から突設したアンテナ把持部で把持して配置している
　このように、電気接続箱のケースの外周縁を利用して金属棒からなるアンテナを保持することができる。 The antenna formed of the metal rod has a horizontal portion placed on a groove-like antenna placement portion provided along the inner surface of the outer peripheral wall of the case, or an antenna projecting from the inner surface of the outer peripheral wall. As described above, the antenna made of a metal rod can be held by using the outer peripheral edge of the case of the electrical junction box.
　アンテナを前記バスバーで形成する場合は、絶縁板上で外周部に延在させて前記ケースの外周壁の内面に沿って配置している。この絶縁板上には車載電装品に給電する分岐接続回路用のバスバーも固定している。 When the antenna is formed of the bus bar, the antenna extends on the outer peripheral portion on the insulating plate and is arranged along the inner surface of the outer peripheral wall of the case. On this insulating plate, a bus bar for a branch connection circuit that supplies power to the on-vehicle electrical components is also fixed.
　電気接続箱内に収容するバスバーは、銅合金等の導電性金属板を所要パターンで打ち抜くと共に加締め孔も打ち抜き加工しており、その後、タブを折り曲げ加工して形成している。該バスバーは、絶縁樹脂板からなる絶縁板の上面に設けたリブを前記加締め孔に挿入し、加締め加工して絶縁板上にバスバーを固定している。
　板状アンテナとして利用するバスバーは、導電性金属板をパターンで打ち抜く際に、同時に打ち抜いて設け、その後、回路部と切断してもよい。あるいは、回路パターン部分とは別に、他の導電性金属板で板状アンテナとするバスバーを設けておき、該バスバーに加締め孔をあけて、絶縁板上に加締め固定してもよい。
　このように、絶縁板上に固定しているバスバーをアンテナとして用いると、電気接続箱内にアンテナ配置用の特別のスペースを設ける必要はなく、電気接続箱が大型化しない。また、バスバーは絶縁板上に加締め固定されているため、該アンテナとするバスバーを固定するための止め具も不要となる。 The bus bar accommodated in the electrical junction box is formed by punching a conductive metal plate such as a copper alloy in a required pattern and punching a crimping hole, and then bending the tab. In the bus bar, a rib provided on the upper surface of an insulating plate made of an insulating resin plate is inserted into the caulking hole, and caulking is performed to fix the bus bar on the insulating plate.
The bus bar used as the plate antenna may be provided by being punched at the same time when the conductive metal plate is punched with a pattern, and then cut off from the circuit portion. Alternatively, in addition to the circuit pattern portion, a bus bar serving as a plate-like antenna may be provided using another conductive metal plate, and a caulking hole may be formed in the bus bar so as to be caulked and fixed on the insulating plate.
As described above, when the bus bar fixed on the insulating plate is used as an antenna, it is not necessary to provide a special space for antenna arrangement in the electrical connection box, and the electrical connection box does not increase in size. Further, since the bus bar is fixed by crimping on the insulating plate, a stopper for fixing the bus bar serving as the antenna is not required.
　前記バスバーと接続した中継用金属棒または前記金属棒の一端と前記基板の無線受信回路の一端とを、半田付けで接続している。
　即ち、基板には前記無線樹脂回路に先端部にスルーホールを設け、該スルーホールにアンテナとなる金属棒、または、バスバーと半田または溶接で接続する中継用金属棒の先端を挿入して半田接続している。 The relay metal bar connected to the bus bar or one end of the metal bar and one end of the wireless reception circuit of the substrate are connected by soldering.
That is, a through-hole is provided at the tip of the wireless resin circuit on the substrate, and the tip of a metal rod serving as an antenna or a relay metal rod connected to the bus bar by soldering or welding is inserted into the through-hole for solder connection. is doing.
　バスバーを加締め固定した絶縁板を複数組積層した積層体を前記基板と隙間を空けて配置し、前記積層体のうち前記基板と対向する絶縁板上のバスバーを前記アンテナとし、該アンテナとするバスバーの屈曲させた一端をタブ状端子とする一方、前記無線受信回路に接続した端子を前記プリント基板に実装したコネクタ内に挿入し、該コネクタに前記バスバーのタブ状端子を挿入して嵌合接続している。 A laminated body in which a plurality of sets of insulating plates with caulking and fixing a bus bar are stacked is arranged with a gap from the substrate, and the bus bar on the insulating plate facing the substrate in the laminated body is used as the antenna, and the antenna is used. While the bent end of the bus bar is used as a tab-shaped terminal, the terminal connected to the wireless receiving circuit is inserted into the connector mounted on the printed circuit board, and the tab-shaped terminal of the bus bar is inserted into the connector and fitted. Connected.
　前記無線受信回路を備えた基板は、ライト、ドアロック、ワイパ、室内灯、パワーウインドのうち少なくとも１つの車両搭載機器を制御するボディ用電子制御ユニットのプリント基板と共用していることが好ましい。
　即ち、電気接続箱の内部に収容するプリント基板は、ドアロック制御部に限らず、他のライト、ワイパ等のボディ系電子制御部を備えたものとすると、前記特許文献１と同様に、多数の電子制御ユニットを車両内部に分散配置する必要がなくなる。かつ、前記ジャンクションボックスからなる電気接続箱では、前記ドアロック、ライト、ワイパ等のボディ系電子制御部で制御する各機器への駆動電源の分配を行っているため、これらの駆動電源の供給制御を前記プリント基板に設けた各制御部からの信号により直接行うことができる。 It is preferable that the board provided with the wireless receiving circuit is shared with the printed board of the body electronic control unit that controls at least one vehicle-mounted device among the light, the door lock, the wiper, the room light, and the power window.
That is, the printed circuit board accommodated in the electric junction box is not limited to the door lock control unit, and is assumed to have other body system electronic control units such as lights and wipers. It is no longer necessary to distribute the electronic control units in the vehicle. In addition, in the electrical junction box comprising the junction box, the drive power supply is distributed to each device controlled by the body system electronic control unit such as the door lock, the light, and the wiper. Can be directly performed by a signal from each control unit provided on the printed circuit board.
　前記アンテナは、断面四角枠形状の前記ケースの少なくとも二辺の周壁内面に沿って延在させ、該アンテナの屈曲角度を９０度以下とし、かつ、
　前記アンテナの全長は、受信する電波の波長λに対して０．９×λ／４以上としていることが好ましい。 The antenna extends along the inner surface of the peripheral wall of at least two sides of the case having a square frame shape in cross section, the bending angle of the antenna is 90 degrees or less, and
The overall length of the antenna is preferably 0.9 × λ / 4 or more with respect to the wavelength λ of the received radio wave.
　アンテナは曲げが少ない程、アンテナ利得が低下しないため、前記のように、アンテナを屈曲させる必要がある場合には屈曲角度を９０度以下としている。
　また、アンテナは受信する電波の波長λに対して０．９×λ／４以上の全長を有するようにして、アンテナ利得を高めている。
　アンテナは樹脂成形品からなるケースの外周壁の内面に沿って配置しているため、樹脂製のケース外周壁が誘電体として機能し、アンテナをケース外周壁に近づけると共振周波数（ｆｎ）が減少し、それに伴いアンテナが受信する電波の波長λに対する全長を短縮でき、従来必要とされていたλ／４以上より若干短い前記０．９×λ／４以上とすることができる。かつ、ケース成形材料となる樹脂の種類に応じて共振周波数が更に減少してアンテナ全長を短くできる。 Since the antenna gain does not decrease as the antenna is bent, the bending angle is set to 90 degrees or less when the antenna needs to be bent as described above.
Further, the antenna gain is increased by having an overall length of 0.9 × λ / 4 or more with respect to the wavelength λ of the received radio wave.
Since the antenna is disposed along the inner surface of the outer peripheral wall of the resin molded product, the resin outer peripheral wall functions as a dielectric, and the resonance frequency (fn) decreases when the antenna is brought closer to the outer peripheral wall of the case. As a result, the total length of the radio wave received by the antenna with respect to the wavelength λ can be shortened to 0.9 × λ / 4 or more, which is slightly shorter than λ / 4 that has been required conventionally. In addition, the resonance frequency is further reduced according to the type of resin used as the case molding material, and the overall length of the antenna can be shortened.
　電気接続箱内への収容する電気部品が多いため電気接続箱が大型となり、その一辺の長さが前記０．９×λ／４以上であれば、板状アンテナとするバスバーあるいは前記金属棒はケースの一辺に沿わせた直線状としている。
　しかしながら、電気接続箱の一辺の長さが前記０．９×λ／４未満であれば、アンテナとするバスバーあるいは前記金属棒は、ケースの周壁内面に沿った位置で絶縁板上に二辺～四辺に沿うように屈曲して設け、アンテナ利得が得られる長さとしている。
　前記絶縁板の周縁に配置するアンテナとなるバスバーに囲まれた絶縁板上の内部には、前記のように、電装品への給電用の分岐接続回路用のバスバーを固定し、絶縁板上のスペースを有効利用している。その際、分岐接続回路用のバスバーとアンテナとするバスバーとの間で電波の干渉が発生しないように、１０～３０ｍｍ程度離して配置し、空気絶縁部を設けておくことが好ましい。 Since there are many electrical parts to be accommodated in the electrical junction box, the electrical junction box becomes large, and if the length of one side is not less than 0.9 × λ / 4, the bus bar or the metal rod used as the plate antenna is It is a straight line along one side of the case.
However, if the length of one side of the electrical junction box is less than 0.9 × λ / 4, the bus bar or the metal rod serving as the antenna is located on the insulating plate at a position along the inner surface of the peripheral wall of the case. It is bent along the four sides, and the antenna gain is obtained.
As described above, the bus bar for the branch connection circuit for feeding power to the electrical components is fixed inside the insulating plate surrounded by the bus bar serving as an antenna disposed at the periphery of the insulating plate, and the insulating plate is mounted on the insulating plate. Make effective use of space. At this time, it is preferable that the air insulation portion is provided by separating the bus bar for the branch connection circuit and the bus bar serving as the antenna by 10 to 30 mm apart so as not to cause radio wave interference.
　前記アンテナは、乗員が携帯するリモートキーまたはスマートキーからの送信信号の受信用として最適であるが、タイヤに装着したタイヤセンサから検出信号の受信用として好適に用いられる。 The antenna is optimal for receiving a transmission signal from a remote key or smart key carried by a passenger, but is preferably used for receiving a detection signal from a tire sensor attached to the tire.
　本発明は、さらに、前記車載用の電気接続箱に収容したアンテナを提供している。
　即ち、本発明のアンテナは、電気接続箱のケース内部において、該ケースの外周壁の内面に沿って配置される金属棒からなるアンテナであり、該アンテナは該ケース内部に収容したプリント基板の無線受信回路と接続されるものである。 The present invention further provides an antenna housed in the in-vehicle electrical junction box.
That is, the antenna of the present invention is an antenna made of a metal rod disposed along the inner surface of the outer peripheral wall of the case inside the case of the electrical junction box, and the antenna is a radio of a printed circuit board housed in the case. It is connected to the receiving circuit.
　上述したように、本発明では、電気接続箱の内部にアンテナを収容し、該アンテナを電気接続箱のケースの外周壁の内面に沿って配置しているため、ケースを大型化することなくアンテナの長さをアンテナ利得が得られるのに十分な長さとすることができる。このように、アンテナ設置スペースを配慮することなく電気接続箱に利得の大きいアンテナを収容することができる。
　また、電気接続箱内に収容する絶縁板上に固定したバスバーをアンテナとして利用すると、アンテナをケース外周壁に保持する必要はなく、アンテナとして用いるバスバーの長さを絶縁板上で所要の長さとすることが簡単にできる。 As described above, in the present invention, the antenna is accommodated inside the electrical connection box, and the antenna is disposed along the inner surface of the outer peripheral wall of the case of the electrical connection box. Therefore, the antenna is not enlarged. Can be long enough to obtain the antenna gain. Thus, an antenna having a large gain can be accommodated in the electrical junction box without considering the antenna installation space.
In addition, when a bus bar fixed on an insulating plate housed in an electric junction box is used as an antenna, it is not necessary to hold the antenna on the outer peripheral wall of the case, and the length of the bus bar used as the antenna is set to the required length on the insulating plate. Easy to do.

Therefore, the printed circuit board 10 protrudes from the upper wall 2b of the case 2 at a height L3 (5 to 50 mm).
　プリント基板１０にドアロック制御部１１となる回路を設けると共にＩＣチップ１３を実装している。該ドアロック制御部１１として、リモートキーからの受信回路１２を備え、該受信回路１２一端をプリント基板１０の一辺縁の外側隅部に設けて、アンテナ２０と接続する給電部１２ａとしている。該受信回路１２と接続したＩＣチップ１３に送信回路１４を接続し、該送信回路１４をプリント基板１０の他辺の下面に実装したコネクタ１５と接続している。 A circuit serving as a door lock control unit 11 is provided on the printed circuit board 10 and an IC chip 13 is mounted. As the door lock control unit 11, a receiving circuit 12 from a remote key is provided, and one end of the receiving circuit 12 is provided at the outer corner of one edge of the printed circuit board 10 to serve as a power feeding unit 12 a connected to the antenna 20. A transmission circuit 14 is connected to the IC chip 13 connected to the reception circuit 12, and the transmission circuit 14 is connected to a connector 15 mounted on the lower surface of the other side of the printed board 10.
　前記コネクタ１５は、ケース２の内部に収容したリレー基板６の回路および積層体５のバスバー３と接続した端子を収容しているコネクタ（図示せず）と嵌合している。これにより、前記送信回路１４もリレー基板６の回路およびバスバー３と接続している。バスバー３は前記のようにケース２の他側に配置したコネクタと接続し、該コネクタをワイヤハーネス端末のコネクタと接続し、該ワイヤハーネスをドアロック駆動部と接続している。該構成とすることで、ドアロック駆動部をドアロック制御部１１により制御することができる。 The connector 15 is fitted with a connector (not shown) that accommodates the circuit of the relay board 6 accommodated in the case 2 and the terminal connected to the bus bar 3 of the laminate 5. Thereby, the transmission circuit 14 is also connected to the circuit of the relay board 6 and the bus bar 3. The bus bar 3 is connected to the connector disposed on the other side of the case 2 as described above, the connector is connected to the connector of the wire harness terminal, and the wire harness is connected to the door lock driving unit. With this configuration, the door lock driving unit can be controlled by the door lock control unit 11.
　前記プリント基板１０には、前記ドアロック制御部１１と共に、ライト、ワイパ、室内灯、パワーウインド等のボディ系機器の制御部も設け、リレー基板６およびバスバー３と接続している。 The printed circuit board 10 is provided with a control unit for body equipment such as a light, a wiper, a room light, and a power window in addition to the door lock control unit 11, and is connected to the relay substrate 6 and the bus bar 3.
　前記プリント基板１０の受信回路１２の給電部１２ａにはスルーホールを設け、該スルーホールに金属棒からなるアンテナ２０の一端を挿入して半田付けで接続している。なお、半田付けに代えて溶接もしくはコネクタ接続でもよい。
　該アンテナ２０は、図１および図２に示すように、給電部１２ａと接続した上端から下向きに高さＬ３だけ下降させ、ケース２の外周壁２ａの上端側内面に沿って形成した図３に示すアンテナ配置部２ｄに到達させ、該到達位置で９０度以下の角度で傾斜させて水平方向に屈曲している。該アンテナ２０の下向き垂直部２０ａの下端の屈曲部２０ｂは、ケース２の長尺方向の外周壁２ａの一端側に近接した箇所に位置する。 A through hole is provided in the power feeding portion 12a of the receiving circuit 12 of the printed circuit board 10, and one end of the antenna 20 made of a metal rod is inserted into the through hole and connected by soldering. In place of soldering, welding or connector connection may be used.
As shown in FIGS. 1 and 2, the antenna 20 is lowered by a height L3 downward from the upper end connected to the power feeding portion 12a and is formed along the inner surface on the upper end side of the outer peripheral wall 2a of the case 2. The antenna arrangement portion 2d shown in FIG. 1 is reached, and is inclined at an angle of 90 degrees or less at the arrival position and bent in the horizontal direction. A bent portion 20 b at the lower end of the downward vertical portion 20 a of the antenna 20 is located at a location close to one end side of the outer peripheral wall 2 a in the longitudinal direction of the case 2.
　前記アンテナ配置部２ｄは、アンテナ２０の屈曲部２０ｂから水平方向に延在する水平部２０ｃを上方から挿入できる溝としている。該溝からなるアンテナ配置部２ｄにアンテナ２０を挿入すると、アンテナ２０は溝内に位置決め保持できるようにしている。
　アンテナ配置部２ｄはケース２の長尺方向の外周壁２ａの内面に沿って形成しているため、その長さは約２００ｍｍであり、該アンテナ配置部２ｄに配置するアンテナ２０の水平部２０ｃの長さをＬ４とし、該水平部を含むアンテナ長さＬ４＋Ｌ３を、受信する電波の波長λに対して、０．９×λ／４以上とすることができる。 The antenna placement portion 2d is a groove into which a horizontal portion 20c extending in the horizontal direction from the bent portion 20b of the antenna 20 can be inserted from above. When the antenna 20 is inserted into the antenna placement portion 2d made of the groove, the antenna 20 can be positioned and held in the groove.
Since the antenna placement portion 2d is formed along the inner surface of the outer peripheral wall 2a in the longitudinal direction of the case 2, the length is about 200 mm, and the horizontal portion 20c of the antenna 20 placed in the antenna placement portion 2d The length is L4, and the antenna length L4 + L3 including the horizontal portion can be set to 0.9 × λ / 4 or more with respect to the wavelength λ of the received radio wave.
　前記電気接続箱１におけるアンテナ２０の組み付けは、プリント基板１０の受信回路１２の給電部１２ａにアンテナ２０の垂直部２０ａの上端を接続した状態でケース２の内部に組みつける。其の際、アンテナ２０は予め垂直部２０ａの下端を屈曲して水平部２０ｃを水平方向に延在させる。
　プリント基板１０をケース２の支柱部２ｃの上端に固定すると、アンテナ２０の垂直部２０ａはケース２の外周壁２ａの長尺側の一端側に近接した位置に垂下し、下端の屈曲部２０ｂはケースの外周壁２ａの内面に沿って形成したアンテナ配置部２ｄに嵌まり込む。この状態で水平部２０ｃをアンテナ配置部２ｄ内に挿入するだけで、ケース２に簡単に取り付けることができる。 The antenna 20 in the electrical junction box 1 is assembled in the case 2 in a state where the upper end of the vertical portion 20a of the antenna 20 is connected to the power feeding portion 12a of the receiving circuit 12 of the printed circuit board 10. At that time, the antenna 20 bends the lower end of the vertical portion 20a in advance to extend the horizontal portion 20c in the horizontal direction.
When the printed circuit board 10 is fixed to the upper end of the support column 2c of the case 2, the vertical portion 20a of the antenna 20 hangs at a position close to one end on the long side of the outer peripheral wall 2a of the case 2, and the bent portion 20b at the lower end is It fits in the antenna arrangement | positioning part 2d formed along the inner surface of the outer peripheral wall 2a of a case. In this state, the horizontal portion 20c can be easily attached to the case 2 simply by being inserted into the antenna placement portion 2d.
　前記のように、本発明の電気接続箱１では、ケース２の外周壁２ａの内面に沿って形成したアンテナ配置部２ｄにアンテナ２０を嵌合して配置しているため、アンテナ２０の長さをλ／４以上とすることができ、アンテナ２０の利得を低減することなく、ケース２の内部に収容することができる。
　また、プリント基板１０に設けた受信回路１２の給電部１２ａに接続するアンテナ２０の垂直部２０ａはケース２の外周壁２ａの隅部に位置し、水平部２０ｃも外周壁２ａの内面に沿って配置される。よって、ケース２の内部に収容するリレー基板６やバスバー３と離れた位置になり、これらから発生するノイズの影響を最小限とすることができる。
　かつ、ケース２の外周壁２ａの内面に沿ってアンテナ２０を配置するため、ケース内部にアンテナ配置用のスペースを設ける必要はなく、ケース２の全体容積をアンテナ配置用に増大する必要はない。 As described above, in the electrical junction box 1 of the present invention, since the antenna 20 is fitted and arranged on the antenna arrangement portion 2d formed along the inner surface of the outer peripheral wall 2a of the case 2, the length of the antenna 20 is increased. Λ / 4 or more, and can be accommodated in the case 2 without reducing the gain of the antenna 20.
Further, the vertical portion 20a of the antenna 20 connected to the power feeding portion 12a of the receiving circuit 12 provided on the printed circuit board 10 is located at the corner of the outer peripheral wall 2a of the case 2, and the horizontal portion 20c is also along the inner surface of the outer peripheral wall 2a. Be placed. Therefore, it becomes the position away from the relay board | substrate 6 accommodated in the inside of the case 2, and the bus-bar 3, and the influence of the noise which generate | occur | produces from these can be minimized.
In addition, since the antenna 20 is arranged along the inner surface of the outer peripheral wall 2a of the case 2, it is not necessary to provide a space for antenna arrangement inside the case, and it is not necessary to increase the entire volume of the case 2 for antenna arrangement.
　前記金属棒からなる長さＬのアンテナ２０と樹脂成形品からなるケースの外周壁内面との距離に応じて発生する共振周波数（ｆｎ）について測定し、共振周波数の波長λｎを算出し、かつ、アンテナとして必要な長さとされている４Ｌ／λｎに対する短縮率を求めた。
　前記ケースはポリプロピレンからなる。
　前記アンテナ２０とケース外周壁内面との距離、共振周波数ｆｎ、共振周波数における電波の自由空間波長λｎから計算したアンテナ長さλｎ／４、およびアンテナ長さＬの前記共振時のアンテナ長さλｎ／４に対する比率４Ｌ／λｎをアンテナの短縮率として下記の表１および図４に示す。 Measure the resonance frequency (fn) generated according to the distance between the antenna L of length L made of the metal rod and the inner surface of the outer peripheral wall of the case made of a resin molded product, calculate the wavelength λn of the resonance frequency, and The shortening rate for 4L / λn, which is considered to be a length necessary for the antenna, was obtained.
The case is made of polypropylene.
The distance between the antenna 20 and the inner surface of the outer peripheral wall of the case, the resonance frequency fn, the antenna length λn / 4 calculated from the free space wavelength λn of the radio wave at the resonance frequency, and the antenna length λn / The ratio 4L / λn to 4 is shown in Table 1 and FIG.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　表１に示すように、アンテナ２０とケース外周壁内面との距離が短い程、共振周波数（ｆｎ）は下がり、波長（λｎ）は長くなり、アンテナ長さＬのλｎ／４に対する比率は減少する。よって、従来はアンテナ長さはλ／４が必要とされていたが、０．９×λ／４以上であればよく、周波数を３１５ＭＨｚにした場合には、従来の必要長さとされるアンテナ長さ２２～２５ｃｍを２１～２４ｃｍと短くできることが確認できた。 As shown in Table 1, the shorter the distance between the antenna 20 and the inner surface of the outer peripheral wall of the case, the lower the resonance frequency (fn), the longer the wavelength (λn), and the ratio of the antenna length L to λn / 4 decreases. . Therefore, in the past, the antenna length was required to be λ / 4, but it may be 0.9 × λ / 4 or more, and when the frequency is set to 315 MHz, the antenna length assumed to be the conventional required length is required. It was confirmed that 22 to 25 cm can be shortened to 21 to 24 cm.
　前記のように、アンテナの長さを短くできるのは、樹脂製のケース外周壁が誘電体として作用し、該誘電体からなる外周壁にアンテナを近づけると共振周波数が下がり、それに伴い、アンテナ長さを短縮できると認められる。よって、ケースを成形する樹脂の種類に応じて、アンテナ長さの最短長さを、０．９×λ／４より更に短い（０．５～０．８）×λ／４とすることも可能であると認められる。
　このように、電気接続箱内でケース外周壁に沿ってアンテナを配置することにより、アンテナ長さを従来より短くしてもアンテナ利得を得ることができる利点も有する。 As described above, the length of the antenna can be shortened because the outer peripheral wall made of resin acts as a dielectric, and when the antenna is moved closer to the outer peripheral wall made of the dielectric, the resonance frequency is lowered. It is recognized that this can be shortened. Therefore, depending on the type of resin for molding the case, the shortest antenna length can be made shorter than 0.9 × λ / 4 (0.5 to 0.8) × λ / 4. It is recognized that
As described above, by arranging the antenna along the outer peripheral wall of the case in the electrical junction box, there is an advantage that the antenna gain can be obtained even if the antenna length is shorter than the conventional one.

　一方、アンテナ２０も前記水平部２０ｃの先端よりさらに９０度以下の角度で傾斜させて水平方向に屈折した延長部２０ｄを設け、アンテナ２０をＸ、Ｙ、Ｚ方向に屈曲した三次元形状としている。該アンテナ２０の延長部２０ｄはアンテナ配置部２ｄ－１にはめ込んで配置している。
　このように、アンテナ２０の長さをさらに長くすると、アンテナ２０の指向性および利得を高めることができる。 5A, 5B, and 5C show a modification of the first embodiment.
In the first modification shown in FIG. 5A, an antenna arrangement portion 2d-1 is provided along the inner surface on the short side of the outer peripheral wall 2a of the case 1, and is continuous with the antenna arrangement portion 2d on the long side.

The extension portion 20d of the antenna 20 is disposed so as to be fitted into the antenna arrangement portion 2d-1.
Thus, if the length of the antenna 20 is further increased, the directivity and gain of the antenna 20 can be increased.
　図５（Ｂ）に示す第２変形例では、第１変形例と同様にアンテナ２０に延長部２０ｄを設けている。該第２変形例では、ケース２の外周壁２ａの短尺側の内面に沿ってコネクタ収容部を設け、アンテナ配置部を設けることが難しいため、ケース２の内部に配置している。このケース内部に配置するアンテナ２０の延長部２０ｄの下方には、空間をあけてヒューズ、リレー等の収容部が位置するが、これら収容部にプラグイン接続するヒューズおよびリレーと干渉しないようにしている。 In the second modification shown in FIG. 5 (B), the antenna 20 is provided with an extension 20d as in the first modification. In the second modified example, the connector housing portion is provided along the short inner surface of the outer peripheral wall 2 a of the case 2, and it is difficult to provide the antenna placement portion. Under the extension portion 20d of the antenna 20 disposed inside the case, there is a space for housing portions such as fuses and relays. However, do not interfere with fuses and relays that are plugged into the housing portions. Yes.
　図５（Ｃ）に示す第３変形例では、アンテナ２０の水平部２０ｃの先端を上向きに屈曲させて第１延長部２０ｄを設け、該第１延長部２０ｄの上端を水平方向に屈曲させて第２延長部２０ｅを設けている。
　アンテナ２０の第２延長部２０ｅは、ケース２に被せるアッパーカバー３０の外周壁３０ａの内面に沿って配置し、第２延長部２０ｅをアッパーカバー３０の上壁の内面に設けたアンテナ配置部３０ｂに嵌合している。 In the third modification shown in FIG. 5C, the tip of the horizontal portion 20c of the antenna 20 is bent upward to provide a first extension portion 20d, and the upper end of the first extension portion 20d is bent in the horizontal direction. A second extension 20e is provided.

Is fitted.
　前記図５（Ａ）（Ｂ）（Ｃ）の変形例は、電気接続箱のケースの外周壁の一辺の長さが短い場合、即ち、電気接続箱が小型である場合に適した構成となり、アンテナの設置スペースを設けるために、電気接続箱を大型化する必要はない。 5 (A), (B), and (C) have a configuration suitable when the length of one side of the outer peripheral wall of the case of the electrical junction box is short, that is, when the electrical junction box is small, There is no need to increase the size of the electric junction box in order to provide an antenna installation space.
　図６（Ａ）（Ｂ）に第１実施形態の第４変形例を示す。
　第４変形例では、ケースの外周壁３０ａの内面に沿って配置するアンテナ２０を、ケース３０の外周壁３０ａに溝状のアンテナ配置部を設ける代わりに、外周壁３０ａの内面から間隔をあけてＬ形状の保持部３０ｘを突設し、該保持部３０ｘと外周壁３０ａの内面との間にアンテナ２０を挿入して挟持している。保持部３０ｘの上端は外周側３０ａへ突出させてアンテナ２０が抜け出せないようにしている。 6A and 6B show a fourth modification of the first embodiment.
In the fourth modification, the antenna 20 arranged along the inner surface of the outer peripheral wall 30a of the case is spaced from the inner surface of the outer peripheral wall 30a instead of providing the groove-shaped antenna arrangement portion on the outer peripheral wall 30a of the case 30. An L-shaped holding part 30x is projected, and the antenna 20 is inserted and sandwiched between the holding part 30x and the inner surface of the outer peripheral wall 30a. The upper end of the holding portion 30x protrudes toward the outer peripheral side 30a so that the antenna 20 cannot be pulled out.
　図７乃至図９に第２実施形態を示す。
　第２実施形態では、アンテナ専用の金属棒を用いず、電気接続箱１内に収容するバスバーの１つを板状アンテナとして利用し、該板状アンテナとするバスバー４０の一端を中継用金属棒２０－Ａと接続し、該中継用金属棒２０－Ａを前記プリント基板１０の受信回路１２の給電部１２ａと接続している。
　第１実施形態と同一部材は同一符号を付して説明を省略する。 7 to 9 show a second embodiment.
In the second embodiment, without using a metal rod dedicated to the antenna, one of the bus bars accommodated in the electrical connection box 1 is used as a plate antenna, and one end of the bus bar 40 serving as the plate antenna is used as a relay metal rod. The relay metal rod 20-A is connected to the power feeding portion 12a of the receiving circuit 12 of the printed circuit board 10.
The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　ケース２の内部には、図７に概略的に示すように、ワイヤハーネス（図示せず）の端末のコネクタとコネクタ接続されるバスバー３を絶縁板４上に加締め固定したものを複数組積層した積層体５をケースの下層部に収容している。最上層のバスバー３Ａの上方の一方側に、統合ボディ用ＥＣＵのプリント基板１０を配置している。該プリント基板１０は第１実施形態と同様に、ケース２の上壁２ｂの上部内面から突設した支持枠で支持して搭載し、プリント基板１０はケース２の上壁２ｂより高さＬ３（５～５０ｍｍ）で突出している。 As shown schematically in FIG. 7, a plurality of sets of a plurality of sets in which a bus bar 3 connected to a connector of a terminal of a wire harness (not shown) and a connector are crimped and fixed on an insulating plate 4 are laminated inside the case 2. The laminated body 5 is accommodated in the lower layer portion of the case. An integrated body ECU printed circuit board 10 is arranged on one side above the uppermost bus bar 3A. As in the first embodiment, the printed circuit board 10 is supported and mounted by a support frame protruding from the upper inner surface of the upper wall 2b of the case 2, and the printed circuit board 10 is higher than the upper wall 2b of the case 2 by a height L3 ( 5 to 50 mm).
　前記プリント基板１０の受信回路１２の給電部１２ａに設けたスルーホールにアンテナとする中継用金属棒２０－Ａの上端を挿入して半田付けで接続している。
　該アンテナとする中継用金属棒２０－Ａは、図７に示すように、給電部１２ａと接続した上端から下向きに高さＬ３だけ突出させている。
　前記中継用金属棒２０－Ａの下端は、前記積層体５の最上層のバスバー３Ａのうち、絶縁板４の外周縁に沿って配置し、ケース２内の隅部まで延在させたバスバー４０の先端部と半田付けで接続し、該バスバー４０を板状アンテナとして用いている。 The upper end of the relay metal rod 20-A serving as an antenna is inserted into a through hole provided in the power feeding portion 12a of the receiving circuit 12 of the printed circuit board 10 and connected by soldering.
As shown in FIG. 7, the relay metal rod 20-A serving as the antenna protrudes downward by a height L3 from the upper end connected to the feeding portion 12a.
The lower end of the relay metal bar 20-A is disposed along the outer peripheral edge of the insulating plate 4 in the uppermost bus bar 3A of the laminate 5 and extends to the corner in the case 2. The bus bar 40 is used as a plate antenna.
　前記積層体５を構成する各組のバスバー３と絶縁板４とは、図９（Ａ）に示すように、導電性金属板を回路パターンに沿って打ち抜き加工すると共に加締め孔３ｈを設けた後に、タブを折り曲げ加工したものであり、絶縁板４に設けた加締めリブ４ｒを加締め孔３ｈに挿入して加締め、これにより、バスバー３を絶縁板４上に固定している。
　前記絶縁板４はケース２の内部の水平断面と略同等な形状とし、ケース２の内部で水平方向全面にわたって配置される。 As shown in FIG. 9A, each set of bus bar 3 and insulating plate 4 constituting the laminate 5 is formed by punching a conductive metal plate along a circuit pattern and providing a caulking hole 3h. After that, the tab is bent, and the caulking rib 4r provided on the insulating plate 4 is inserted into the caulking hole 3h and caulked, thereby fixing the bus bar 3 on the insulating plate 4.
The insulating plate 4 has a shape substantially equivalent to the horizontal cross section inside the case 2 and is disposed over the entire surface in the horizontal direction inside the case 2.
　前記最上層のバスバー３Ａも絶縁板４上に加締め固定している。該バスバー３Ａのうち、前記板状アンテナとして用いるバスバー４０は絶縁板４の二辺の外周縁の全長に沿った位置に、水平方向でＬ形状に屈曲させて配置している。よって、該板状アンテナとするバスバー４０の全長は３００ｍｍ程度となる。さらに、該バスバー４０と接続する前記中継用金属棒２０－Ａの長さが５～５０ｍｍとしているため、板状アンテナとなるバスバー４０と中継用金属棒２０－Ａを含めたアンテナ部分の長さは３０５～３５０ｍｍとなる。よって、アンテナの長さを０．９×λ／４以上とすることができる。 The uppermost bus bar 3A is also crimped and fixed on the insulating plate 4. Of the bus bar 3A, the bus bar 40 used as the plate-like antenna is arranged at a position along the entire length of the outer peripheral edge of the two sides of the insulating plate 4 and bent in an L shape in the horizontal direction. Therefore, the overall length of the bus bar 40 as the plate antenna is about 300 mm. Further, since the length of the relay metal rod 20-A connected to the bus bar 40 is set to 5 to 50 mm, the length of the antenna portion including the bus bar 40 and the relay metal rod 20-A serving as a plate antenna is increased. Is 305 to 350 mm. Therefore, the length of the antenna can be 0.9 × λ / 4 or more.
　該絶縁板４上に固定したバスバー３Ａは、前記外周に沿って配置する板状アンテナとするバスバー４０以外に、車載電装品への給電用の分岐接続回路部３１も絶縁板４の中央領域から他方の二辺に沿った位置に設けている。前記板状アンテナとするバスバー４０と隣接する前記分岐接続回路部３１のバスバーとの間には１０～３０ｍｍの隙間Ｓを空けている。 The bus bar 3A fixed on the insulating plate 4 has a branch connection circuit part 31 for feeding power to the vehicle-mounted electrical components from the central region of the insulating plate 4 in addition to the bus bar 40 that is a plate-like antenna disposed along the outer periphery. It is provided at a position along the other two sides. A gap S of 10 to 30 mm is provided between the bus bar 40 serving as the plate antenna and the bus bar of the branch connection circuit portion 31 adjacent thereto.
　前記のように、第２実施形態では、ケース２の外周壁２ａの内面に沿って配置する絶縁板４上のバスバー４０を板状アンテナとして用いているため、アンテナの長さを０．９×λ／４以上とすることができ、アンテナの利得を低減することなく、ケース２の内部に収容することができる。
　また、プリント基板１０に設けた受信回路１２の給電部１２ａに接続する中継用金属棒２０－Ａの垂直部２０ａをケース２の外周壁２ａの隅部に位置して前記板状アンテナとなるバスバー４０の一端と接続している。よって、ケース２の内部に収容するリレーや他のバスバーと離れた位置になり、これらから発生するノイズの影響を最小限とすることができる。
　かつ、ケース２の外周壁２ａの内面に沿って配置するバスバー４０を板状アンテナとして利用しているだけであるため、ケース内部にアンテナ配置用のスペースを設ける必要はなく、ケース２の全体容積をアンテナ配置用に増大する必要はない。さらに、板状アンテナとするバスバー４０は絶縁板４に他のバスバー３と同様に加締め固定されるため、アンテナを固定する止め具も不要となる。 As described above, in the second embodiment, since the bus bar 40 on the insulating plate 4 arranged along the inner surface of the outer peripheral wall 2a of the case 2 is used as a plate antenna, the length of the antenna is 0.9 ×. It can be set to λ / 4 or more, and can be accommodated in the case 2 without reducing the gain of the antenna.
In addition, the vertical portion 20a of the relay metal rod 20-A connected to the power feeding portion 12a of the receiving circuit 12 provided on the printed circuit board 10 is positioned at the corner of the outer peripheral wall 2a of the case 2 and serves as the plate antenna. 40 is connected to one end. Therefore, it becomes a position away from the relays and other bus bars housed in the case 2, and the influence of noise generated therefrom can be minimized.
In addition, since the bus bar 40 arranged along the inner surface of the outer peripheral wall 2a of the case 2 is only used as a plate-like antenna, it is not necessary to provide a space for antenna arrangement inside the case, and the entire volume of the case 2 Need not be increased for antenna placement. Further, since the bus bar 40 serving as a plate-like antenna is caulked and fixed to the insulating plate 4 in the same manner as the other bus bars 3, a fastener for fixing the antenna is also unnecessary.
