When DC power is supplied from the vehicle-side connector 200 to the control circuit 15 via the connection terminals 16a and 16b and the connector terminals 5a and 5b, the control circuit 15 generates a three-phase AC current by a known operation, and the motor terminal A three-phase alternating current is supplied to the coil of the stator unit 9 through 19a, 19b, and 19c. The stator section 9 generates a rotating magnetic field in the circumferential direction by the three-phase alternating current, and the rotor section 11 in which different magnetic poles are alternately formed in the rotating direction on the outer peripheral surface facing the stator core of the stator section 9 follows the rotating magnetic field. Then 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。 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.

なお、制御回路１５には、接続端子１６ｃからエンジンの消費量に基づく電気信号が供給されているため、ステータ部９のコイルに発生する回転磁界はエンジンの消費量に基づく電気信号に比例して回転する。
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され、ポンプコネクタ５からブリント基板１５ａに配設されたパススルー導体１５ｈを通り、車両側コネクタ２００を介して、図示しない燃料メーターに燃料１の液面レベル信号が出力される。 Since the control circuit 15 is supplied with an electrical signal based on the consumption of the engine from the connection terminal 16c, the rotating magnetic field generated in the coil of the stator portion 9 is proportional to the electrical signal based on the consumption of the engine. Rotate.
On the other hand, the level of the fuel 1 in the fuel tank 2 is detected by a float that moves the height of the fuel 1 in the fuel tank 2 up and down by buoyancy by the liquid level detector 14, A liquid level signal of the fuel 1 is output to a fuel meter (not shown) via the vehicle-side connector 200 through the pass-through conductor 15h disposed in 15a.

図４、図５は、実施の形態１の制御回路部の変形例を示すもので、プリント基板１５ａの第２の接続孔１５ｆの配設位置を変更したものである。
即ち、図４、図５に示すように、第２の接続孔１５ｆが、円板状に形成された取付ブラケット１０の外形に対して同心円状に形成されており、第１の接続孔１５ｅと略Ｌ字形状になるように配設したものである。これによって、取付ブラケット１０に所定の間隔で一体的にモールド成形されたコネクタ端子５ａ〜５ｅと、モータ部３０に接続されるモータ端子１９ａ、１９ｂ、１９ｃ及び液面レベル信号端子２１ａ、２１ｂとの接続を容易にすると共に、第１の接続孔１５ｅと第２の接続孔１５ｆとの配設位置を近くすることにより、パススルー導体１５ｈが短かくなるようにしている。 4 and 5 show a modification of the control circuit unit according to the first embodiment, in which the arrangement position of the second connection hole 15f of the printed circuit board 15a is changed.
That is, as shown in FIGS. 4 and 5, the second connection hole 15f is concentrically formed with respect to the outer shape of the mounting bracket 10 formed in a disk shape, and the first connection hole 15e and It is arranged so as to be substantially L-shaped. Thus, the connector terminals 5a to 5e integrally molded with the mounting bracket 10 at a predetermined interval, and the motor terminals 19a, 19b and 19c and the liquid level signal terminals 21a and 21b connected to the motor unit 30 are provided. In addition to facilitating connection, the pass-through conductor 15h is shortened by making the arrangement positions of the first connection hole 15e and the second connection hole 15f closer.

While being molded integrally with the bracket 10, the connector terminals 5a to 5e, the motor terminals 19a to 19c, and the liquid level signal terminals 21a and 21b are connected to the first connection hole 15e and the second connection hole of the printed circuit board 15a. Since it is erected from the same direction (same surface side) with respect to 15f, connector terminals 5a-5e and motor terminals 19a-19 And the first connecting hole 15e of the liquid level signal terminal 21a, and 21b printed board 15a, it is possible easily and reliably fitted interpolating the second connection hole 15f. Accordingly, the connector terminals 5a to 5e, the motor terminals 19a to 19c, the liquid level signal terminals 21a and 21b, and the control circuit 15 are surely connected, and the operation is facilitated.

さらにまた、第２の接続孔１５ｆが取付ブラケット１０に対して同心円状に形成されたものでは、ステータ部９のコイルに接続されるモータ端子１９ａ〜１９ｃの導出が容易になるという効果がある。
なお、上記の説明はモータ部３０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良い。 Further, the wiring positions of the first connection hole 15e and the second connection hole 15f shown in FIGS. 4 and 5 are formed close to the connector terminals 5a to 5e, the motor terminals 19a to 19c, and the liquid level.

In addition, although the said description demonstrated the example in which the motor part 30 was a brushless motor, a motor with a brush may be sufficient.

実施の形態２．
図６はこの発明の実施の形態２の燃料供給装置と、車両側コネクタを示す概略平面図、図７は図６の短絡部材の平面図である。
大排気量の車両においては、燃料供給装置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取付ブラケット上面への設置が困難で、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。
実施の形態２の燃料供給装置はこのような要求に応じたものであり、以下に大形化された制御回路１５０により制御される燃料供給装置１０１について、図６、図７を用いて説明する。 Embodiment 2. FIG.
6 is a schematic plan view showing a fuel supply device and a vehicle-side connector according to Embodiment 2 of the present invention, and FIG. 7 is a plan view of a short-circuit member of FIG.
In a large displacement vehicle, the fuel supplied from the fuel supply device has a large capacity, so the energizing current is large and the control circuit becomes large. It is necessary to install at the installation location.
The fuel supply apparatus according to the second embodiment meets such a requirement, and the fuel supply apparatus 101 controlled by the control circuit 150 which has been enlarged will be described below with reference to FIGS. .

図６、図７において、中間コネクタ部３００は、燃料供給装置１０１のモータ部の駆動電流を制御する制御回路１５０、制御回路１５０にリードワイヤー２２を介して接続されポンプコネクタ５に結合される結合部１６０、車両側コネクタ２００に結合される車両側結合部１７０を有している。   6 and 7, the intermediate connector unit 300 is connected to the control circuit 150 that controls the drive current of the motor unit of the fuel supply device 101, and the control circuit 150 via the lead wire 22 and coupled to the pump connector 5. Part 160 and a vehicle side coupling part 170 coupled to the vehicle side connector 200.

取付ブラケット１０には短絡部材２３が収納されており、この短絡部材２３はプリント基板２３ａで形成されており、プリント基板２３ａには、ポンプコネクタ５のコネクタ端子５ａ〜５ｅが嵌挿されて半田付けにより電気的に固着される第１の接続孔２３ｂ、モータ端子１９ａ〜１９ｃと液面レベル信号端子２１ａ、２１ｂが嵌挿されて半田付けにより電気的に固着される第２の接続孔２３ｃ、第１の接続孔２３ｂと第２の接続孔２３ｃとの間を短絡接続し、モータ部３０へ供給する駆動電流及び液面検出装置１４からの液面レベル信号を、燃料供給装置１０１から車両側コネクタ２００へパススルーするプリント配線であるパススルー導体２３ｄが配設されている。   A short-circuit member 23 is accommodated in the mounting bracket 10, and this short-circuit member 23 is formed of a printed board 23a. The connector terminals 5a to 5e of the pump connector 5 are inserted into the printed board 23a and soldered. The first connection hole 23b, which is electrically fixed by the motor terminal 19a-19c, and the liquid level signal terminals 21a, 21b are inserted and the second connection hole 23c, which is electrically fixed by soldering, The first connection hole 23b and the second connection hole 23c are short-circuited to connect the drive current supplied to the motor unit 30 and the liquid level signal from the liquid level detection device 14 to the vehicle side connector from the fuel supply device 101. A pass-through conductor 23 d which is a printed wiring passing through to 200 is provided.

なお、リードワイヤー２２は車両により中間コネクタ３００部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、上述した実施の携帯１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。
上記以外は実施の形態１の燃料供給装置１００と同様である。 The lead wire 22 is formed so that the length of the lead wire 22 can be changed according to the mounting location because the mounting location of the intermediate connector 300 varies depending on the vehicle.
The control circuit 150 is substantially the same as the configuration of the mobile phone 1 described above, but is made larger 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.
Other than the above, the fuel supply device 100 is the same as that of the first embodiment.

次に、以上のように構成された実施の形態２の燃料供給装置１０１の動作について、図６、図７を参照して説明する。
まず、燃料供給装置１０１のポンプコネクタ５と、中間コネクタ部３００の結合部１６０、中間コネクタ部３００の車両側結合部１７０と車両側コネクタ２００の結合部１６を嵌合させる。
車両側コネクタ２００から、接続端子１６ａ、１６ｂ、コネクタ端子５ａ、５ｂを通して制御回路１５０に直流電力が供給されると、制御回路１５０は、周知の動作により三相交流電流を生成する。
三相交流電流は、リードワイヤー２２、結合部１６０、ポンプコネクタ５、短絡部材２３のパススルー導体２３ｄ、モータ端子１９ａ、１９ｂ、１９ｃを介して、ステータ部９のコイルに三相交流電流が供給され、ステータ部９の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。 Next, the operation of the fuel supply apparatus 101 of the second embodiment configured as described above will be described with reference to FIGS.
First, the pump connector 5 of the fuel supply apparatus 101, the coupling portion 160 of the intermediate connector portion 300, the vehicle side coupling portion 170 of the intermediate connector portion 300, and the coupling portion 16 of the vehicle side connector 200 are fitted.
When DC power is supplied from the vehicle-side connector 200 to the control circuit 150 through the connection terminals 16a and 16b and the connector terminals 5a and 5b, the control circuit 150 generates a three-phase AC current by a known operation.
The three-phase alternating current is supplied to the coil of the stator portion 9 through the lead wire 22, the coupling portion 160, the pump connector 5, the pass-through conductor 23d of the short-circuit member 23, and the motor terminals 19a, 19b, and 19c. The rotor portion 11 that generates a rotating magnetic field in the circumferential direction of the stator portion 9 and has magnetic poles that are alternately different in the rotating direction on the outer peripheral surface facing the stator core of the stator portion 9 rotates following the rotating magnetic field.

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。
なお、制御回路１５０には接続端子１６ｃからエンジンの消費量信号が供給されているため、ステータ部９のコイルに発生する回転磁界は消費量信号に比例して回転する。
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され、ポンプコネクタ５からブリント基板２３ａに配設されたパススルー導体２３ｄを通り、車両側コネクタ２００を介して、図示しない燃料メーターに燃料１の液面レベル信号が出力される。 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.
Since the control circuit 150 is supplied with the engine consumption signal from the connection terminal 16c, the rotating magnetic field generated in the coil of the stator portion 9 rotates in proportion to the consumption signal.
On the other hand, the liquid level of the fuel 1 in the fuel tank 2 is detected by a float that moves the height of the fuel 1 in the fuel tank 2 up and down by buoyancy by the liquid level detection device 14, and from the pump connector 5 to the blind substrate. A liquid level signal of the fuel 1 is output to a fuel meter (not shown) through the vehicle-side connector 200 through the pass-through conductor 23d disposed in the terminal 23a.

以上のように、この発明の実施の形態２の燃料供給装置１０１によれば、コネクタ端子、モータ端子と、制御回路との接続が確実で、作業が容易に行えるという実施の形態１と同様の効果に加え、車両の種類に係らず、小排気量から大排気量の車両に対応できる燃料供給装置を得ることができる。   As described above, according to the fuel supply device 101 of the second embodiment of the present invention, the connection between the connector terminal, the motor terminal, and the control circuit is reliable, and the operation can be performed easily. In addition to the effects, it is possible to obtain a fuel supply device that can handle a vehicle with a small displacement to a large displacement regardless of the type of vehicle.
