The drive of the fuel pump is controlled. However, in a large displacement vehicle, the energization current is large and the control circuit becomes large, so that it is difficult to install on the upper surface of the mounting bracket, and it is necessary to mount it at a mounting location away from the mounting bracket. On the other hand, in a two-wheeled vehicle, for example, a vehicle with a small displacement of 125 cc or less, the mounting space is limited, and thus it is necessary to install the mounting bracket on the upper surface. Therefore, a control circuit must be prepared to be installed on the mounting bracket and installed on a place away from the mounting bracket, and a dedicated mounting bracket is required for each. There was a problem of becoming.

It is something that can be done.

A vehicle-side connector 300 for supplying power is further connected to the intermediate connector portion 200.

図２を参照して、燃料供給装置１０００は、燃料ポンプモジュール１００と、後述の制御回路１５が収納された中間コネクタ部２００で構成されており、例えば、二輪車において、燃料ポンプモジュール１００は、燃料１を貯蔵する燃料タンク２の開口部２ａに気密部材であるパッキン３を介して吊装され、中間コネクタ部２００を通して車両側コネクタ３００から電力が供給されている。   Referring to FIG. 2, the fuel supply apparatus 1000 includes a fuel pump module 100 and an intermediate connector portion 200 in which a control circuit 15 described later is accommodated. For example, in a motorcycle, the fuel pump module 100 is a fuel pump module 100. 1 is suspended from an opening 2 a of a fuel tank 2 that stores 1 via a packing 3 that is an airtight member, and electric power is supplied from a vehicle-side connector 300 through an intermediate connector portion 200.

先ず、燃料ポンプモジュール１００の構造を説明する。燃料ポンプモジュール１００は、例えば、ポリアセタール樹脂などの熱可塑性樹脂で形成され、燃料タンク２内の燃料１を吐出する吐出パイプ４、中間コネクタ部２００から供給された電力を後述のモータ部３０に供給するポンプコネクタ５が形成された取付ブラケット１０、ポンプベース６及びポンプカバー７にインペラ８を収容して構成されたポンプ部２０、ポンプ部２０を駆動する、ステータ部９とローター部１１で構成される、所謂、ブラシレスモータであるモータ部３０、吐出パイプ４から吐出される燃料を濾過する吐出フィルタ１２、ポンプ部２０に流入する燃料１を濾過する吸込フィルタ１３、燃料タンク２内の燃料１の液面レベルをフロートにより検出し、ポンプコネクタ５から中間コネクタ部２００、車両側コネクタ３００（図１参照）を介して、図示しない車両側の燃料レベル表示装置に燃料１の液面レベル信号を出力する液面検出装置１４とから構成されている。   First, the structure of the fuel pump module 100 will be described. The fuel pump module 100 is formed of, for example, a thermoplastic resin such as polyacetal resin, and supplies the electric power supplied from the discharge pipe 4 that discharges the fuel 1 in the fuel tank 2 and the intermediate connector part 200 to the motor part 30 described later. The mounting bracket 10 is formed with a pump connector 5, the pump base 6 and the pump cover 7 are configured by accommodating the impeller 8, the stator portion 9 that drives the pump portion 20, and the rotor portion 11. A so-called brushless motor 30, a discharge filter 12 that filters the fuel discharged from the discharge pipe 4, a suction filter 13 that filters the fuel 1 flowing into the pump unit 20, and the fuel 1 in the fuel tank 2. The liquid level is detected by a float, and from the pump connector 5 to the intermediate connector portion 200 and the vehicle side connector 30. Through (see FIG. 1), and a liquid level detection apparatus 14 for outputting the liquid level signal of the fuel 1 in a fuel level display device for a vehicle (not shown) side.

本実施の形態におけるポンプの形式はいわゆるタービンポンプである。円盤状に形成されたインペラ８は、ポンプベース６及びポンプカバー７によりその表裏両面側から挟むようにして収容され、ローター部１１に中心部が係合すると共に回転自在に形成されている。インペラ８の外周側およびポンプベース６及びポンプカバー７のインペラ８に対向する側には、それぞれＣ字状のポンプ流路が形成されており、燃料タンク２内の燃料１はポンプカバー７に結合された吸込フィルタ１３で濾過され、インペラ８の回転によりポンプ流路内を流れつつ昇圧され、モータ部３０側に圧送される。ポンプ部２０からモータ部３０側に圧送された燃料は、ステータ部９とローター部１１との間隙を通り、吐出パイプ４を介して図示しないエンジンに供給される。   The type of pump in the present embodiment is a so-called turbine pump. The impeller 8 formed in a disc shape is accommodated so as to be sandwiched from both the front and back sides by the pump base 6 and the pump cover 7, and is formed so as to be rotatable while the center portion is engaged with the rotor portion 11. C-shaped pump flow paths are respectively formed on the outer peripheral side of the impeller 8 and the side of the pump base 6 and the pump cover 7 facing the impeller 8, and the fuel 1 in the fuel tank 2 is coupled to the pump cover 7. The suction filter 13 is filtered, and the pressure is increased while flowing in the pump flow path by the rotation of the impeller 8, and the pressure is fed to the motor unit 30 side. The fuel pumped from the pump unit 20 to the motor unit 30 side passes through the gap between the stator unit 9 and the rotor unit 11 and is supplied to an engine (not shown) via the discharge pipe 4.

モータ部３０は、ブラシレスモータが採用されている。ステータ部９は、磁性体からなるステータコアにコイルが巻回されている。円筒状のローター部１１は、例えば、ＰＰＳ（ポリフェニレンスルフィド）等の熱可塑性樹脂材に磁性粉を練り込んで円筒状に形成されたプラスティックマグネットであり、ステータ部９のステータコアと向き合う外周面側に回転方向に交互に異なる磁極を形成するように着磁されている。   The motor unit 30 is a brushless motor. The stator unit 9 has a coil wound around a stator core made of a magnetic material. The cylindrical rotor portion 11 is a plastic magnet formed into a cylindrical shape by kneading magnetic powder into a thermoplastic resin material such as PPS (polyphenylene sulfide), and is formed on the outer peripheral surface of the stator portion 9 facing the stator core. It is magnetized so as to form different magnetic poles alternately in the rotation direction.

また、ステータ部９のコイルには車両側コネクタ３００から、中間コネクタ部２００、及びポンプコネクタ５を介して三相交流電流が供給され、周方向に回転磁界を発生するように例えばスター結線されている。   Further, a three-phase alternating current is supplied to the coil of the stator portion 9 from the vehicle-side connector 300 via the intermediate connector portion 200 and the pump connector 5, and is star-connected, for example, so as to generate a rotating magnetic field in the circumferential direction. Yes.

燃料ポンプモジュール１００の上部を覆うブラケット１０には、図で水平方向に着脱口を有するポンプコネクタ５が設置されている。ポンプコネクタ５には後で詳述する中間コネクタ部２００がコネクタ接続される。さらに、図２には示していないが、中間コネクタ部２００には、後方から車両側コネクタ３００がコネクタ接続されようになっている。   The bracket 10 that covers the upper portion of the fuel pump module 100 is provided with a pump connector 5 that has a detachable opening in the horizontal direction in the figure. The pump connector 5 is connected to an intermediate connector portion 200 which will be described in detail later. Further, although not shown in FIG. 2, a vehicle-side connector 300 is connected to the intermediate connector portion 200 from behind.

次に、図１を参照して、燃料ポンプモジュール１００と中間コネクタ部２００と車両側コネクタ３００とについて説明する。燃料ポンプモジュール１００のポンプコネクタ５は、ブラケット１０に一体に形成された筺体からなり、図２における水平方向の一方向に開口している。筺体内部にはモータ部３０に接続されたピン５ａと液面検出装置１４に接続されたピン５ｂが植設されている。   Next, the fuel pump module 100, the intermediate connector part 200, and the vehicle side connector 300 will be described with reference to FIG. The pump connector 5 of the fuel pump module 100 is formed of a housing integrally formed with the bracket 10 and opens in one horizontal direction in FIG. A pin 5 a connected to the motor unit 30 and a pin 5 b connected to the liquid level detection device 14 are implanted in the housing.

中間接続部２００は、燃料ポンプモジュール１００のモータ部３０への駆動電流を制御する制御回路１５を備えている。制御回路１５は、図３、図４に示すように、筺体に収納されたプリント板１５ａの表面に制御信号を発生する集積回路１５ｂ、電解コンデンサ１５ｃ、スイッチング素子１５ｄ、接続端子１６ａの一端が嵌挿されて半田付けにより電気的に固着される接続孔１５ｅ、接続端子１７ａの一端が嵌挿されて半田付けにより電気的に固着される接続孔１５ｆ及びスイッチング素子１５ｄとの間を接続する接続導体１５ｇが配設された制御信号部を形成している。制御信号部は所定の動作により燃料ポンプモジュール１００のモータ部３０の駆動電流を制御する。さらに、プリント基板１５ａ上には、液面検出装置１４の液面レベル信号を燃料ポンプモジュール１００から車両側コネクタ３００へパススルーするパススルー導体１５ｊとその接続孔１５ｈ、１５ｉが設けられている。なお、接続端子１６ａ、１６ｂの一端及び接続端子１７ａ、１７ｂの一端はそれぞれＬ形形状に形成されており、プリント板１５ａに対して同一方向から嵌挿されており、接続孔１５ｅ、１５ｆ、１５ｈ、１５ｉとの半田付けが容易である。   The intermediate connection unit 200 includes a control circuit 15 that controls a drive current to the motor unit 30 of the fuel pump module 100. As shown in FIGS. 3 and 4, the control circuit 15 has an integrated circuit 15b that generates a control signal on the surface of the printed board 15a accommodated in the housing, an electrolytic capacitor 15c, a switching element 15d, and one end of a connection terminal 16a. The connection conductor 15e that is inserted and fixed electrically by soldering, the connection hole 15f that is inserted into one end of the connection terminal 17a and electrically fixed by soldering, and the switching element 15d. 15g is formed as a control signal portion. The control signal unit controls the drive current of the motor unit 30 of the fuel pump module 100 by a predetermined operation. Further, on the printed circuit board 15a, there are provided pass-through conductors 15j for passing through the liquid level signal of the liquid level detection device 14 from the fuel pump module 100 to the vehicle-side connector 300, and connection holes 15h and 15i thereof. Note that one end of each of the connection terminals 16a and 16b and one end of each of the connection terminals 17a and 17b are formed in an L shape and are inserted into the printed board 15a from the same direction, and are connected to the connection holes 15e, 15f, and 15h. , 15i is easy to solder.

以上のように構成された中間コネクタ部２００は、制御回路１５が第一結合部１６と第二結合部１７を有した筐体内に収納された状態で、例えば、シリコン樹脂などのポッティング剤１９を充填され、外部からの水、塵の侵入に対して保護される。   The intermediate connector section 200 configured as described above is configured such that the potting agent 19 such as silicon resin is applied in a state where the control circuit 15 is housed in a housing having the first coupling section 16 and the second coupling section 17. Filled and protected against ingress of water and dust from outside.

中間接続部２００は、制御回路１５の筺体の一端に第一結合部１６を、反対端に第二結合部１７を、それぞれ制御回路１５と一体に設けている。第一結合部１６は前方に開放口を有し、内部には制御回路１５の端子１５ｅ、１５ｈに接続された雌形の接続端子１６ａ、１６ｂが設けられていて、第一接続部１６をポンプコネクタ５に着装するとき、ピン５ａ、５ｂにコネクタ接続するようになされている。第二結合部１７は後方に開放口を有し、内部には制御回路１５の端子１５ｆ、１５ｉに接続された雄形の接続端子１７ａ、１７ｂが設けられていて、車両側コネクタ３００に着装されるとき、ピン雌形接続端子１８ａ、１８ｂにコネクタ接続するようになされている。第一結合部１６の接続端子１６ａ、１６ｂと第二結合部１７の接続端子１７ａ、１７ｂは雌雄の関係にある番形状に形成されている。   The intermediate connection part 200 is provided integrally with the control circuit 15 with the first coupling part 16 at one end of the housing of the control circuit 15 and the second coupling part 17 at the opposite end. The first coupling portion 16 has an opening at the front, and female connection terminals 16a and 16b connected to the terminals 15e and 15h of the control circuit 15 are provided therein, and the first connection portion 16 is pumped. When the connector 5 is worn, the connector is connected to the pins 5a and 5b. The second connecting portion 17 has an open port on the rear side, and male connection terminals 17 a and 17 b connected to the terminals 15 f and 15 i of the control circuit 15 are provided inside the second connecting portion 17 and is attached to the vehicle-side connector 300. In this case, a connector is connected to the female female connection terminals 18a and 18b. The connection terminals 16a and 16b of the first coupling part 16 and the connection terminals 17a and 17b of the second coupling part 17 are formed in a number shape having a male-female relationship.

さらにまた、第一結合部１６と第二結合部１７とは、制御回路１５を挟んで反対向きで、同一線上に配置されている。従って、中間接続部２００をポンプコネクタ５及び車両側コネクタ３００に着脱する際には、着脱を同一の方向で行なうことができる。   Furthermore, the first coupling portion 16 and the second coupling portion 17 are arranged on the same line in opposite directions with the control circuit 15 in between. Therefore, when the intermediate connection part 200 is attached to and detached from the pump connector 5 and the vehicle-side connector 300, the attachment and detachment can be performed in the same direction.

以上のように構成された燃料供給装置１０００の動作を説明する。まず、例えば、１２５ｃｃ以下の小排気量の車両において、取付けスペースの制限から、制御回路を取付ブラケットの上面へ設置する必要がある場合について説明する。この場合、燃料ポンプモジュール１００のポンプコネクタ５と中間コネクタ２００の第一結合部１６を嵌合させ、中間コネクタ２００の第二結合部１７と車両側コネクタ３００の結合部１８を嵌合させる。この場合、制御回路１５と第一結合部１６と第二結合部１７とは着脱方向が同じになるようほぼ同一直線上に形成されているので、接続作業が容易であるとともに、中間コネクタ部設置による燃料供給装置全体のスペースを低減できる。   The operation of the fuel supply apparatus 1000 configured as described above will be described. First, for example, in a vehicle with a small displacement of 125 cc or less, a case will be described in which the control circuit needs to be installed on the upper surface of the mounting bracket due to the limitation of the mounting space. In this case, the pump connector 5 of the fuel pump module 100 and the first coupling portion 16 of the intermediate connector 200 are fitted, and the second coupling portion 17 of the intermediate connector 200 and the coupling portion 18 of the vehicle-side connector 300 are fitted. In this case, since the control circuit 15, the first coupling portion 16, and the second coupling portion 17 are formed on substantially the same straight line so that the attaching / detaching directions are the same, the connection work is easy and the intermediate connector portion is installed. The space of the whole fuel supply device can be reduced.

車両側コネクタ３００から中間コネクタ２００に直流電力が供給されると、中間コネクタ部２００に収納された制御回路１５は、周知の動作により三相交流電流を生成し、燃料ポンプモジュール１００のステータ部９のコイルに三相交流電流が供給され周方向に回転磁界を発生し、ステータ部９のステータコアと向き合う外周面側に回転方向に交互に異なる磁極が形成されたローター部１１は回転磁界に追従して回転する。   When DC power is supplied from the vehicle-side connector 300 to the intermediate connector 200, the control circuit 15 housed in the intermediate connector unit 200 generates a three-phase AC current by a known operation, and the stator unit 9 of the fuel pump module 100. A three-phase alternating current is supplied to the coil of this coil to generate a rotating magnetic field in the circumferential direction. Rotate.

ローター部１１が回転すると、ポンプ部２０のインペラ８の回転により燃料がポンプ流路内を流れつつ昇圧され、モータ部３０側に圧送される。ポンプ部２０からモータ部３０側に圧送された燃料は、ステータ部９とローター部１１との間隙を通り、吐出パイプ４を介して図示しないエンジンに供給される。一方、燃料タンク２内の燃料１の液面レベルは、液面検出装置１４によって、燃料タンク２内の燃料１の高さ位置を浮力により上下するフロートにより位置検出し、ポンプコネクタ５から中間コネクタ部２００のプリント板１５ａに配設されたパススルー導体１５ｊを通り、車両側コネクタ３００を介して、図示しない燃料レベル表示装置に燃料１の液面レベル信号が出力される。パススルー導体１５ｊを制御回路１５に付加したことにより、燃料レベルの検出に専用の導体を設ける必要がなくなる。   When the rotor unit 11 rotates, the fuel is pressurized while flowing in the pump flow path by the rotation of the impeller 8 of the pump unit 20 and is pumped to the motor unit 30 side. The fuel pumped from the pump unit 20 to the motor unit 30 side passes through the gap between the stator unit 9 and the rotor unit 11 and is supplied to an engine (not shown) via the discharge pipe 4. On the other hand, the liquid level of the fuel 1 in the fuel tank 2 is detected by the liquid level detection device 14 by the float that moves the height of the fuel 1 in the fuel tank 2 up and down by buoyancy. A level signal of the fuel 1 is output to a fuel level display device (not shown) through the vehicle-side connector 300 through the pass-through conductor 15j disposed on the printed board 15a of the unit 200. By adding the pass-through conductor 15j to the control circuit 15, it is not necessary to provide a dedicated conductor for detecting the fuel level.

次に、大排気量の車両においては、燃料ポンプモジュールが吐出する燃料が大容量であることから通電電流が大きく制御回路が大形化するため、制御回路を取付ブラケット上面へ設置することは困難で、取付ブラケットから離れた取付場所に取り付ける必要がある。以下、大形化された制御回路１５０を備える燃料供給装置１００１について図５を用いて説明する。   Next, in a large displacement vehicle, since the fuel discharged from the fuel pump module has a large capacity, the energizing current is large and the control circuit becomes large, so it is difficult to install the control circuit on the top surface of the mounting bracket. Therefore, it is necessary to install it at a mounting location away from the mounting bracket. Hereinafter, the fuel supply apparatus 1001 including the control circuit 150 that has been enlarged will be described with reference to FIG.

図５において、中間コネクタ部２０１は、燃料ポンプモジュール１０１のモータ部の駆動電流を制御する制御回路１５０、この制御回路１５０にリードワイヤー２１を介して接続され、ポンプコネクタ５０に結合される第一結合部１６０、車両側コネクタ３００に結合される第二結合部１７０を有している。   In FIG. 5, the intermediate connector unit 201 is connected to the control circuit 150 that controls the drive current of the motor unit of the fuel pump module 101, the control circuit 150 via the lead wire 21, and is coupled to the pump connector 50. It has the coupling | bond part 160 and the 2nd coupling | bond part 170 couple | bonded with the vehicle side connector 300. FIG.

なお、リードワイヤー２１は車両により中間コネクタ２０１の装着場所が異なってくるため、装着場所に対応して長さを変えられるように形成されている。また、制御回路１５０は、上述した制御回路１５の構成とほぼ同様であるが、大電流に対応するためにスイッチング素子にヒートシンクなどの図示しない放熱部材が装着され、大形化されている。ポンプコネクタ５０、第一結合部１６０、及び第二結合部１７０は、それぞれ図１に示すポンプコネクタ５、第一結合部１６、及び第二結合部１７と同様に構成されているので、詳細は省略する。なお、燃料供給装置１００１の動作については、前述した動作と同様である。   In addition, since the mounting location of the intermediate connector 201 differs depending on the vehicle, the lead wire 21 is formed so that the length can be changed according to the mounting location. The control circuit 150 is substantially the same as the configuration of the control circuit 15 described above, but is enlarged by mounting a heat dissipation member (not shown) such as a heat sink on the switching element in order to cope with a large current. The pump connector 50, the first coupling portion 160, and the second coupling portion 170 are configured in the same manner as the pump connector 5, the first coupling portion 16, and the second coupling portion 17 shown in FIG. 1, respectively. Omitted. The operation of the fuel supply device 1001 is the same as the operation described above.

以上のように、この発明の燃料供給装置によれば、中間コネクタ部はポンプコネクタに電気的結合される第一結合部と車両側コネクタに電気的結合される第二結合部を有し、第一結合部と第二結合部は番形状に形成され、また、結合部の着脱が同一の平面で行なえるので、組み立てが容易であるとともに、制御回路を有する中間接続部を車両の種類に応じて、取付ブラケットの上面部、または取付ブラケット以外の取付場所に取り付けることができ、複数の車両の種類に対して、取付ブラケットを複数種類を用意することがないため、金型費用が安価で対応できる燃料供給装置を提供することができる。また、制御回路にパススルー導体を付加しているので、別の導体を用いることなく、制御以外の電気情報を燃料ポンプモジュールから取り出すことができる。なお、上記の説明はモータ部がブラシレスモータの例を説明したが、ブラシ付モータでもよい。   As described above, according to the fuel supply device of the present invention, the intermediate connector portion has the first coupling portion electrically coupled to the pump connector and the second coupling portion electrically coupled to the vehicle-side connector, The one connecting part and the second connecting part are formed in a numbered shape, and the connecting part can be attached and detached on the same plane, so that the assembly is easy and the intermediate connecting part having a control circuit is provided according to the type of vehicle. It can be mounted on the top surface of the mounting bracket or at a mounting location other than the mounting bracket, and there is no need to prepare multiple types of mounting brackets for multiple types of vehicles. A fuel supply device that can be provided can be provided. Moreover, since the pass-through conductor is added to the control circuit, electrical information other than control can be taken out from the fuel pump module without using another conductor. In the above description, an example in which the motor unit is a brushless motor has been described. However, a motor with a brush may be used.
