However, the partition wall provided in the pump module described in Patent Document 1 surrounds the periphery of the wiring terminal. For this reason, when moisture contained in the fuel accumulates inside the partition wall, there arises a problem that the connector terminal, the wiring terminal, or the wiring corrodes or galvanizes. In addition, there is a problem that the partition wall becomes a barrier when the wiring terminal and the connector terminal are connected. If the partition wall is abolished in order to solve these problems, there is a concern that a plurality of wiring terminals contact each other and the wirings are short-circuited.
The present invention has been made in view of the above points, and an object of the present invention is to provide a pump module capable of suppressing wiring corrosion or electrolytic corrosion and preventing a short circuit between the wirings.

  The pump module of the present invention includes a fuel pump, a flange, a plurality of connector terminals, a plurality of wires, a clamp, and a protective tube. The fuel pump is housed inside the flange. The plurality of connector terminals are incorporated in the flange and have an external terminal protruding from the outer wall of the flange and an internal terminal protruding from the inner wall of the flange. A plurality of wirings electrically connect the plurality of internal terminals and the drive part of the fuel pump. The clamp is provided on the outer wall of the fuel pump and locks a plurality of wires or one wire. The protective tube covers the outside of at least one of the plurality of wires, and is provided between the inner wall of the flange where the internal terminal protrudes and the clamp.

The filter portion 30 is formed in a bag shape whose outer shape is substantially L-shaped, and is provided in the gap between the fuel pump 20 and the flange 10. The fuel pipe 32 included in the cap portion 31 is liquid-tightly connected to the suction port 23 of the fuel pump 20. The fuel in the fuel tank 2 passes through the filter part 30 and is sucked into the suction port 23 of the fuel pump 20 from the fuel pipe 32 of the cap part 31.

  A mounting plate 33 is provided on the housing 21 of the fuel pump 20. A liquid level detector 34 can be attached to the attachment plate 33. The liquid level detector 34 changes the electric resistance value of the current flowing through the liquid level detector 34 in accordance with the height of the liquid level of the fuel in the fuel tank 2.

  A connector portion 40 is provided on the bottom 11 of the flange 10. As shown in FIGS. 3 to 5, a plurality of connector terminals 41 are resin-molded in the connector portion 40. Thus, the plurality of connector terminals 41 are incorporated in the flange 10. Of the connector terminal 41, a portion protruding from the outer wall of the flange 10 is referred to as an external terminal 42 (see FIG. 5), and a portion protruding from the inner wall of the flange 10 is referred to as an internal terminal 43.

The flange 10 is provided with a pedestal 44 protruding from the inner wall of the bottom 11 at a position where the internal terminal 43 protrudes. In the present embodiment, the upper surface 45 of the pedestal portion 44 corresponds to an example of “an inner wall of the flange 10 where the internal terminal 43 protrudes”. The pedestal portion 44 can suppress the moisture from touching the internal terminal 43 even when moisture contained in the fuel accumulates at the bottom 11 of the flange 10.
On the upper surface 45 of the pedestal portion 44, a partition wall 46 is provided between the plurality of internal terminals 43 and the internal terminals 43. A plurality of partition walls 46 are provided in the direction in which the plurality of internal terminals 43 are arranged. A space 47 formed between the plurality of partition walls 46 and the partition wall 46 is opened in a direction different from the direction in which the plurality of internal terminals 43 are arranged, that is, in the radial direction of the cylindrical portion 12 in this embodiment. ing. This prevents water contained in the fuel from accumulating in the space 47.

A wiring terminal 51 is connected to the end of the plurality of wirings 50 on the internal terminal 43 side by crimping or the like. Each of the plurality of wiring terminals 51 is inserted outside the corresponding plurality of internal terminals 43. Thereby, the plurality of wirings 50 and the plurality of internal terminals 43 corresponding thereto are electrically connected.
Here, let A be the distance between the end 511 of the wiring terminal 51 opposite to the pedestal 44 and the upper surface 45 of the pedestal 44. Further, the distance between the end 461 of the partition wall 46 opposite to the pedestal 44 and the upper surface 45 of the pedestal 44 is B. At this time, the two distances have a relationship of A> B. Thus, by lowering the partition wall 46 than the wiring terminal 51, when the wiring terminal 51 is held with a jig or the like and connected to the internal terminal 43, the jig and the partition wall 46 interfere with each other. This prevents the work from becoming difficult. Therefore, the wiring terminal 51 and the internal terminal 43 can be easily connected.

  Of the plurality of wirings 50, the two wirings 50 that electrically connect the two internal terminals 43 and the drive unit of the fuel pump 20 are referred to as power wirings 501 and 502. In addition, among the plurality of wirings 50, two wirings 50 that electrically connect two internal terminals 43 different from the internal terminals 43 connected to the power wirings 501 and 502 and the liquid level detector 34 are detected. These are referred to as wirings 503 and 504. In this embodiment, in FIG. 3 or FIG. 4, the ground power wiring 501, the power wiring 502 for power supply, the detection wiring 503 for ground, and the detection wiring 504 for power supply are arranged in this order from the right side. Note that the arrangement of the plurality of wirings 50 is not limited to that shown in FIG. 3 or FIG.

A protective tube 60 is placed outside the power wiring 502 for power supply and the detection wiring 504 for power supply. The protective tube 60 is made of an insulating material such as resin and covers the wiring terminal 51 together with the wiring 50. By providing the protective tube 60 for every other four wirings 50, when the wiring terminal 51 tilts, the protective tube 60 can prevent the plurality of wiring terminals 51 from contacting each other.
Further, in the power wirings 501 and 502 and the detection wirings 503 and 504, the protective tube 60 is provided on at least one of the ground wirings 501 and 503 and the power wirings 502 and 504, so that the internal terminal 43 and the wiring It is possible to suppress the electrolytic corrosion of the terminal 51 or the wiring 50.

As shown in FIG. 1, a first clamp 71, a second clamp 72, and a third clamp 73 are provided on the outer wall of the housing 21 of the fuel pump 20.
The first clamp 71 is provided between the plurality of extending portions 13 and the extending portions 13. Further, the first clamp 71 is provided at a position shifted in the circumferential direction of the fuel pump 20 with respect to the pedestal portion 44. The first clamp 71 locks the four wires 50 at positions where the four wires 50 are exposed from the cylindrical portion 12 of the flange 10. In addition, the 1st clamp 71 is good also as what latches the at least 1 wiring 50 in which the protection tube 60 was provided.
The second clamp 72 is provided between the first clamp 71 and the terminal of the drive unit, and locks the two power wirings 501 and 502.
The third clamp 73 is provided between the first clamp 71 and the liquid level detector 34 and locks the two detection wires 503 and 504.

  As shown in FIG. 6, the first clamp 71 has a clamp base 74, a first arm portion 75, a second arm portion 76, and a claw portion 77. The clamp table 74 is provided on the outer wall of the housing 21 of the fuel pump 20 and has a radially outward surface formed flat. The first arm portion 75 extends from the clamp base 74 in the radially outward direction of the fuel pump 20. The second arm portion 76 extends in parallel with the clamp table 74 from the end of the first arm portion 75 opposite to the clamp table 74. The claw portion 77 protrudes from the end of the second arm portion 76 opposite to the first arm portion 75 toward the clamp base 74. The first clamp 71 has a gap portion 78 through which the wiring 50 is inserted between the clamp base 74 and the second arm portion 76. The gap 78 is set to a size that is smaller than the outer diameter of the protective tube 60 and does not pass through the protective tube 60. Thereby, the first clamp 71 can limit the range in which the protective tube 60 moves along the wiring 50 between the upper surface 45 of the base portion 44 and the second arm portion 76 of the first clamp 71. is there.

FIG. 5 shows a state in which the end portion 62 of the protective tube 60 on the first clamp 71 side and the second arm portion 76 of the first clamp 71 are in contact with each other. The distance between the end 61 on the pedestal 44 side of the protective tube 60 and the upper surface 45 of the pedestal 44 in this state is C. Further, as described above, the distance between the end portion 461 of the partition wall 46 opposite to the pedestal portion 44 and the upper surface 45 of the pedestal portion 44 is B. At this time, the two distances have a relationship of B> C. As a result, the protective tube 60 extends to the pedestal 44 side from the end 461 opposite to the pedestal 44 of the partition wall 46 and covers the wiring terminal 51. Therefore, the protective tube 60 can prevent a short circuit between the adjacent wiring terminals 51 even when the wiring terminals 51 are inclined.
Further, the protective tube 60 can suppress corrosion or electrolytic corrosion of the internal terminal 43, the wiring terminal 51, or the wiring 50 by covering the wiring terminal 51 to a position close to the upper surface 45 of the pedestal portion 44.

Next, a method for assembling the flange 10 and the fuel pump 20 will be described.
This assembly method is performed in the order of a wiring connection process, a temporary placement process, a fitting process, and a clamping process.
First, in the wiring connection process, as shown in FIG. 3, the wiring terminal 51 is connected to the internal terminal 43 protruding inside the flange 10. Next, the protective tube 60 is attached to the predetermined wirings 502 and 504 and the wiring terminal 51 crimped to the wiring 50. At this time, it is preferable that the end portion 61 on the side of the pedestal portion 44 is in contact with the upper surface 45 of the pedestal portion 44 or the protective tube 60 is located close to the upper surface 45 of the pedestal portion 44. Subsequently, the four wires 50 are drawn out from between the extending portion 13 and the extending portion 13 to the outside of the diameter of the flange 10.

Next, in the temporary placement step, as shown in FIGS. 7 and 8, the flange 10 and the fuel pump 20 are positioned in the circumferential direction, and the fitting pawl 28 of the fuel pump 20 is placed on the extending portion 13 of the flange 10. Put on. 7 and 8, most of the portions where the four wires 50 are exposed from the protective tube 60 are omitted.
7 and 8, it is assumed that the end portion 61 of the protective tube 60 on the pedestal portion 44 side and the upper surface 45 of the pedestal portion 44 are in contact with each other. In this state, the end 62 on the opposite side of the pedestal 44 is positioned closer to the first clamp 71 than the end 11 on the bottom 11 side of the fuel pump 20.

As shown in FIG. 7, let D be the distance between the end 62 of the protective tube 60 opposite to the pedestal 44 and the end surface 35 of the fuel pump 20 on the bottom 11 side. Further, E is the distance between the end surface 35 on the bottom 11 side of the fuel pump 20 and the upper surface 45 of the pedestal 44. At this time, the length of the protective tube 60 is set longer than D + E. Thereby, when the fuel pump 20 is inserted inside the flange 10 in the fitting step subsequent to the temporary placement step, the end 62 of the protective tube 60 opposite to the base portion 44 is on the bottom 11 side of the fuel pump 20. It is possible to prevent the protective tube 60 from being deformed by being pushed by the end face 35.
As shown in FIG. 8, the protective tube 60 has a length that allows the end 62 on the side opposite to the pedestal portion 44 to be exposed in the recesses 17 between the plurality of extending portions 13 and the extending portions 13. It is preferable to set this. Thereby, it is possible to fix the protective tube 60 between the plurality of extending portions 13 and the extending portions 13 with a jig or the like.

  Subsequently, in the fitting process, the fuel pump 20 is inserted inside the flange 10. At this time, the plurality of extending portions 13 are pressed radially outward by the fitting claws 28 of the fuel pump 20 and elastically deformed in that direction. When the fitting claw 28 of the fuel pump 20 is inserted to the position of the fitting hole 16 of the flange 10, the plurality of extending portions 13 are returned in the radial direction by elastic force. Thereby, the fitting claw 28 of the fuel pump 20 and the fitting hole 16 of the flange 10 are fitted by a snap fit.

  Finally, in the clamping process, the two power wires 501 and 502 and the two detection wires 503 and 504 are locked to the first clamp 71, and the two power wires 501 and 502 are locked to the second clamp 72. Then, the two detection wires 503 and 504 are locked to the third clamp 73. As described above, the gap 78 included in the first clamp 71 is set to a size that does not allow the protective tube 60 to be inserted. Therefore, when the four wires 50 are locked to the first clamp 71, the protective tube 60 placed on the predetermined wire 50 is not locked to the first clamp 71, and the upper surface 45 of the base portion 44. It is provided between the first clamp 71.
