Japanese Patent Laid-Open No. 11-243822

  In the fishing electric reel of Patent Document 1, a lead wire is drawn out from the side surface of the protective cover in the axial direction of the electric motor using the space on the side of the reel body. However, considering the downsizing of the reel, in such a lead wire drawing structure, the dimension of the reel body is increased in the axial direction of the electric motor. This tendency becomes more conspicuous when an electric motor having a large output is mounted, and there is a demand for improvement.

  The present invention has been made to solve the above-described problems, and has an object to provide an electric fishing reel capable of mounting an electric motor with a large output while reducing the size of a reel body. To do.

  An electric reel for fishing according to the present invention that solves such a problem includes an electric motor that is disposed between side plates of a reel body and that rotationally drives a spool, and a cylindrical motor case that houses the electric motor. An electric reel for fishing, wherein a lead wire outlet of the electric motor is formed on an outer peripheral surface of an end portion of the motor case.

  In this fishing electric reel, the lead wire can be pulled out, for example, in a direction orthogonal to the axis of the motor case through the outlet of the motor case. Thereby, it can avoid that a lead wire extends in the axial direction of an electric motor.

  In the electric fishing reel, a waterproof packing may be secured to the pull-out port. With such a configuration, the sealing performance of the outlet can be ensured even when the internal pressure in the case increases due to the heat generated by the electric motor while preventing water from entering the motor case.

  In the fishing electric reel, when the waterproof packing is attached to the doorway from the outside of the outer peripheral surface, the waterproof packing prevents the outer side of the waterproof packing from coming out of the outlet. A holding member may be provided. By comprising in this way, since waterproof packing can be attached to an extraction outlet from the outer side of an outer peripheral surface, it is excellent in attachment property. In addition, the packing body can be reliably prevented from being detached by the holding member.

  In the electric fishing reel, the lead wire may be led out radially outward from the outer peripheral surface of the end of the electric motor. By comprising in this way, the lead wire led out to the radial direction outer side from the outer peripheral surface of the edge part of an electric motor can be pulled out to the exterior from the outlet of a motor case as it is.

  In this fishing electric reel, the bottom of the motor case can be disposed adjacent to the end of the electric motor. Therefore, it is possible to effectively prevent the reel body from becoming larger in the axial direction of the electric motor, and to reduce the size.

  According to the electric reel for fishing of the present invention, the lead wire can be pulled out, for example, in a direction perpendicular to the axis of the motor case through the outlet of the motor case, and the lead wire extends in the axial direction of the electric motor. Can be avoided. Therefore, the dimension of the reel body can be reduced in the axial direction of the electric motor as compared with the conventional case. As a result, an electric motor with a large output can be mounted while reducing the size of the reel body.

  In addition, the waterproof packing prevents water from entering the motor case, and even when the internal pressure in the electric motor increases due to the heat generated by the electric motor, the sealing performance of the outlet can be secured. The water tightness in the case can be reliably maintained. Therefore, the performance of the electric motor can be stably maintained over a long period.

  Moreover, since the waterproof packing can be attached to the outlet from the outside of the outer peripheral surface of the motor case, the attachment is excellent. In addition, the packing body can be reliably prevented from being detached by the holding member. Therefore, an electric fishing reel excellent in assembling property and productivity can be obtained.

  Further, since the lead wire is led out radially outward from the outer peripheral surface of the end portion of the electric motor and is directly pulled out from the outlet of the motor case, the electric motor and the motor case can be reduced in the axial direction. . Therefore, the dimension of the reel body can be reduced in the axial direction of the electric motor as compared with the conventional case. As a result, a fishing electric reel capable of mounting an electric motor with a large output while reducing the size of the reel body is obtained.

As shown in FIG. 6, the outlet 604 passes through the lid 62 and includes a cylindrical portion 604b and a stepped portion 604a formed at the opening edge of the cylindrical portion 604b. As shown in FIG. 5, a pair of screw attachment portions 605 and 605 are formed on the opening edge of the outlet 604 (opening edge of the stepped portion 604a) at positions symmetrical with respect to the outlet 604. Yes. Each screw mounting portion 605 is formed with a screw hole 605b. A screw 615 can be screwed into each screw hole 605b.

  The waterproof packing 610 is, for example, a synthetic rubber packing, and is attached to the outlet 604 from the outside of the outer peripheral surface 601. The waterproof packing 610 seals the outlet 604 in a liquid-tight manner. The waterproof packing 610 includes a barrel portion 611 that is fitted into the cylindrical portion 604b of the outlet 604, and a flange portion 612 that is continuous with the barrel portion 611 and is disposed at the stepped portion 604a of the outlet 604. The waterproof packing 610 has two through holes 613 and 613 through which the lead wires 54 and 54 are inserted. Each through hole 613 holds the lead wire 54 in a liquid-tight manner. The opening edge part of each through-hole 613 protrudes outside annularly. Thereby, the opening edge part of the through-hole 613 is reinforced.

  A washer 614 as a holding member is disposed on the upper surface of the flange portion 612 of the waterproof packing 610. The washer 614 enters the stepped portion 604a of the outlet 604 by tightening the screw 615 screwed into the screw hole 605b of each screw mounting portion 605, and the waterproof packing 610 (flange portion 612) is placed outside the outlet 604. The removal is suppressed by the lower surface of the head of the screw 615 (the movement of the waterproof packing 610 is restricted).

  In the present embodiment, the lead wires 54 are pulled out obliquely upward to the rear, which is the radial direction of the electric motor M (the radial direction of the motor case 60) through the outlet 604. The two lead wires 54 and 54 drawn out are from a control board or the like provided in the counter case 14 by using a space formed between the lid 62 inside the right side plate 30B and the support portion 31. Are electrically connected to an electric wire (not shown).

  As shown in FIG. 8, an engagement portion 602 a that protrudes to the right is formed on the bottom portion 602 of the lid 62. The engaging portion 602 a is engaged with a round recess 37 c (see FIG. 5) formed on the opposing surface of the side heat radiating member 37. An insertion hole 602b into which the shaft portion 56 of the electric motor M is inserted is formed inside the engaging portion 602a. On the inner surface (left side surface) of the bottom portion 602, an engagement protrusion 602e that protrudes toward the electric motor M is formed. The engaging protrusion 602e can be engaged with a recess 55 provided on the right side of the electric motor M. By this engagement, the right side portion of the electric motor M is positioned on the lid 62.

  The heat generated from the electric motor M is transmitted to the side heat radiating member 37 through the lid 62 which is a part of the motor case 60, and the reel main body 1 passes from the side heat radiating member 37 through the opening 34a of the right side plate 30B. It is radiated to the outside air on the right side.

  As shown in FIG. 4 (b), the right side plate 30B is inserted into a screw hole 36a provided at a peripheral edge thereof with a space therebetween, and fixing screws 36b are inserted into the right frame 2b. It is fixed to the frame 2b.

  According to the electric reel for fishing of the present embodiment described above, each lead wire 54 can be pulled out in a direction perpendicular to the axis of the motor case 60 through the outlet 604 of the motor case 60. Thereby, it is possible to avoid the extension of each lead wire 54 in the axial direction of the electric motor M. Therefore, the dimension of the reel body 1 can be made smaller in the axial direction of the electric motor M than in the prior art. Thereby, the electric motor M with a large output can be mounted while reducing the size of the reel body 1.

  Further, the waterproof packing 610 can prevent water from entering the motor case 60. Further, even when the internal pressure in the electric motor M increases due to the heat generated by the electric motor M, the sealing performance of the outlet 604 can be ensured. Thereby, the water tightness in the motor case 60 can be suitably secured. Therefore, the performance of the electric motor M can be stably maintained over a long period.

  Moreover, since the waterproof packing 610 can be attached to the outlet 604 from the outer side of the outer peripheral surface 601 of the lid 62, the attachment is excellent. In addition, the waterproof packing 610 can be reliably prevented from being detached by the holding member 614. Therefore, an electric fishing reel excellent in assembling property and productivity can be obtained.

  In addition, each lead wire 54 is led out radially outward from the outer peripheral surface 50 of the end portion of the electric motor M, and is pulled out from the outlet 604 of the motor case 60 as it is, so that the electric motor M and the motor case 60 are pivoted. It can be downsized in the direction. Therefore, the dimension of the reel body 1 can be made smaller in the axial direction of the electric motor M than in the prior art. As a result, an electric fishing reel capable of mounting the electric motor M having a large output while reducing the size of the reel body 1 is obtained.

As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.
For example, as shown in FIG. 9, a gap 58 is provided inside the lid 62 </ b> A of the motor case 60, and each lead wire 54 is led out from the side surface 57 of the electric motor M <b> 1 using this gap 58, and thereafter The motor case 60 may be configured to be led out in the radial direction from each of the outlets 604 formed in the outer peripheral surface 601A of the lid 62A of the motor case 60.

  Also in this case, each lead wire 54 can be pulled out radially outwardly perpendicular to the axis of the motor case 60. Thereby, it is possible to avoid the extension of each lead wire 54 in the axial direction of the electric motor M1. Therefore, the dimension of the reel body can be reduced in the axial direction of the electric motor M1 as compared with the conventional case. Thus, the electric motor M1 having a large output can be mounted while reducing the size of the reel body.

In the above-described embodiment, each lead wire 54 is drawn obliquely upward and rearward through the outlet 604. However, the present invention is not limited to this, and each lead wire 54 can be drawn backward, upward, or in other directions according to the layout. it can.
Two outlets 604 may be provided adjacent to each other in the circumferential direction, and the lead wire 54 may be drawn out from each outlet 604, or two outlets 604 may be provided at intervals in the circumferential direction.
Although the outlet 604 is formed in the lid 62 constituting the motor case 60, the front frame 2c constituting the motor case 60 is extended in the axial direction from the end of the electric motor M, and this extended front frame is provided. The lead wire 54 may be drawn out radially outward from the outlet formed in the outer peripheral portion of 2c.

Further, other electric wires may be routed through the outlet 604.
Further, the side heat radiating member 37 is not necessarily provided. In this case, a configuration in which the motor case 60 directly faces the opening 34a of the right side plate 30B can be employed. By configuring in this way, the reel body 1 can be downsized by the amount that the side heat radiating member 37 is not disposed.
