Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to an electrical component storage case, and more particularly to an electrical component storage case for a fishing reel in which an electrical component including a switch for operating a fishing reel and a circuit board for connecting the electrical component are stored.
[0002]
[Prior art]
  Some ship fishing reels developed for boat fishing are equipped with a case for displaying a water depth called a counter case (an example of an electrical component storage case). The counter case contains electrical components including switches and liquid crystal display devices for power on / off and various settings, and a circuit board for connecting the electrical components. An opening for exposing the operation member of the switch to the surface is formed. Corrosive liquids such as seawater tend to adhere to the counter case of such fishing reels, so it is necessary to make the case waterproof to prevent the liquid from entering the internal electrical circuit from the opening. There is.
[0003]
  A conventional counter case having a waterproof structure generally includes a case body mounted on a reel body and having a space formed therein, and a switch operation member having an operation unit for operating a switch. The inside of the case is sealed with an operation member.
[0004]
  The switch operation member includes an operation unit and a seal unit that is integrally formed with the operation unit and extends around the operation unit to urge the operation unit toward the side away from the circuit board. The case body has a lower case attached to the reel body and an upper case attached to the lower case. The upper case is formed with an opening through which an operation portion of the switch operation member is exposed, and is opened inside. A storage space for storing a switch operating member having a wall surface surrounding the switch is formed.
[0005]
  In the fishing reel counter case having such a configuration, the inside of the case is sealed by sandwiching the seal portion of the switch operating member between the tip of the wall surface and the circuit board, thereby preventing liquid from entering the circuit board from the opening. is doing. And in order to pinch | interpose a seal | sticker part reliably between a wall surface and a circuit board, the circuit board is screwed by the upper case at several places around the storage space.
[0006]
[Problems to be solved by the invention]
  In the conventional configuration, since the circuit board is screwed to the upper case to seal the seal portion, the force to pinch the seal portion is weak when the screw stop portion is located far from the storage space. Thus, a sealing failure between the circuit board and the end of the wall surface may occur. For this reason, in the conventional configuration, in order to prevent defective sealing, many screws are required around the storage space, and the number of screws increases.
[0007]
  On the other hand, since the circuit board is made of a relatively thin synthetic resin, the circuit board may be deformed when an external force is applied during screwing or the like. When the circuit board is deformed, there is a possibility that electrical defects such as short circuit or disconnection of wiring formed on the circuit board and destruction of the soldered element may occur. If the number of screws is increased to prevent a sealing failure, the circuit board is likely to be deformed, which may cause an electrical failure or destruction of the element.
[0008]
  An object of the present invention is to reliably seal an electrical component storage case by suppressing deformation of a circuit board.
[0009]
[Means for Solving the Problems]
  An electrical component storage case for a fishing reel according to a first aspect of the present invention is a case in which an electrical component including a switch for reel operation and a circuit board for connecting the electrical component are stored in a reel body of the fishing reel.

The case main body is mounted on the reel main body, and has an opening formed on one surface and a storage space having a wall surface surrounding the opening. The switch operation member is disposed inside the storage space, and is provided with an operation part exposed from the opening for performing the operation of the switch, a flexible enlargement part extending around the operation part, and an edge part of the enlargement part It is a member which has a seal part which extends in a cylindrical shape and contacts the wall surface. The adhesion memberAdheres to the inside of the sealFor pressing the seal part to the wall surface sideMetal tubular partIt is a material.
[0010]
  In this electrical component storage case, when the operation portion exposed from the opening of the switch operation member is pressed, the operation portion bends at the enlarged portion and moves to the circuit board side, and the switch connected to the circuit board is turned on. Even if liquid enters from the opening, the seal portion that extends in a cylindrical shape from the edge of the enlarged portion and contacts the wall surface is pressed by the contact member and is in close contact with the wall surface of the case body. The liquid is less likely to enter the circuit board side from the gap. Here, since the cylindrical seal portion is tightly adhered to the wall surface by the contact member, it is not necessary to press the seal portion with a screw for fixing the circuit board. For this reason, it is possible to minimize the screws for mounting the circuit board, and it is possible to reliably seal the electrical component storage case by suppressing the deformation of the circuit board.
[0011]
  Moreover, since it adheres to the wall surface side by the hard metal cylindrical contact member, almost the entire seal portion can be pressed, and the sealing performance at the seal portion is improved.
[0012]
  An electrical component storage case for a fishing reel according to a second aspect of the present invention is the case according to the first aspect, wherein the enlarged portion biases the operating portion away from the circuit board. In this case, the operation unit can be moved away from the circuit board after the switch is turned on without providing a separate urging member.

In this case, since the plurality of operation portions are sealed together, the case sealing structure is simplified.
[0014]
  An electrical component storage case for a fishing reel according to a fourth aspect of the present invention is the case according to any one of the first to third aspects, wherein the switch operating member is made of a synthetic resin elastic body that is integrally molded and has insulation. In this case, since the switch operation member is made of a synthetic resin elastic body, the operation portion, the enlarged portion, and the seal portion can be easily integrally formed, and the gap between the portions is eliminated, thereby improving the sealing performance.
[0015]
  invention5An electrical component storage case for a fishing reel according to the invention 14In the case described in any one of the above, the case main body can store the circuit board between the first case member mounted on the reel main body and the first case member, and the storage space and the opening are formed.

These packings 25, 26a and 26b seal the bottom of the counter case 4 to prevent liquid from entering from the bottom.
[0035]
  Since the switch operation members 50 to 54 have basically the same configuration, the basic configuration of the switch operation members 50 to 54 will be described with reference to FIG. The switch operation member 53 is an integrally formed member made of a synthetic resin elastic body. The switch operation member 53 includes an operation portion 53a provided with a tip projecting from the switch opening 27d to operate the switch SW5, an enlargement portion 53b integrally formed with the operation portion 53a and extending around the operation portion 53a, and an enlargement The seal portion 53c extends in a cylindrical shape from the edge of the portion 53b and contacts the wall surface 29d. Synthetic resin elastic bodies used for the switch operating members 50 to 54 include styrene-butadiene-rubber (SBR), acrylonitrile-butadiene-rubber (NBR), butadiene-rubber, isoprene-rubber, chloroprene-rubber, silicone-rubber, urethane. -Insulating synthetic rubbers such as rubber are preferred.
[0036]
  The operation portion 53a is a rectangular parallelepiped portion, and a movable contact 60 constituting a switch element of the switch SW5 is fixed to the bottom surface thereof. A pair of fixed contacts 61 are formed on the circuit board 36 so as to face the movable contact 60. The enlarged portion 53b extends in a plate shape with a slight thickness from the periphery on the proximal end side of the operation portion 53a to a position in contact with the wall surface 29d. The enlarged portion 53b is provided to cover the gap from the operation portion 53a to the wall surface 29d and to urge the operation portion 53a in a direction away from the circuit board 36. Due to the action of the enlarged portion 53b, when the hand is released after the operation portion 53a is pressed, the operation portion 53a automatically returns in a direction away from the circuit board 36. The seal portion 53c is formed in a cylindrical shape so as to be in contact with the step portion of the wall surface 29d along the circuit board 36 side. An adhesion member 58 is in close contact with the inside of the seal portion 53c.
[0037]
  The adhesion member 58 is a metal cylindrical member such as a stainless alloy, and has a shape along the seal portion 53c. The contact member 58 presses the seal portion 53c toward the wall surface 29d, thereby bringing the seal portion 53c into close contact with the wall surface 29d. As a result, even if the switch opening 27d is provided in the first case member 20 in order to perform the switch operation, it is difficult for the liquid to enter the case main body 19 from the upper surface side. In addition, since the sealing portion 53c is pressed and sealed against the cylindrical wall surface 29d by the contact member 58, the number of screws for mounting the circuit board 36 can be reduced, and the circuit is mounted when the circuit board 36 is mounted. The substrate 36 becomes difficult to deform.

It is used for operation (for example, deceleration operation), and the right operation unit 51a is used for operation of the switch SW3 (for example, speed increase operation). The enlarged portion 51b connects the two operation portions 51a and 51b and extends around the two operation portions 51a and 51b. The enlarged portion 51b between the operation portions 51a and 51a is formed to be bent in a U shape, and when the one operation portion 51a is operated, the other operation portion does not move along with it. .
[0040]
  As shown in FIGS. 3 and 4, a switch element 62 having a push button 62 a is provided inside the switch operation member 50 instead of a switch element having a movable contact and a fixed contact. 50 a presses the push button 62 a of the switch element 62. Therefore, the movable contact is not fixed to the operation unit 50a.
[0041]
  Further, as shown in FIGS. 1 and 5, the switch operating member 54 for mode setting is housed in a circular switch opening 27e, the operation portion 54a is cylindrical, and the tip is from the switch opening 27e. Although it is exposed, it is disposed so as to be recessed from the switch opening 27e. This is to prevent an erroneous operation of the mode setting operation. When changing the mode, the operation unit 54a must be operated using a ballpoint pen or the like having a thin tip.
[0042]
  In the counter case 4 having such a configuration, when the switch operation members 50 to 54 are mounted on the first case member 20, first, the operation members 50 to 54 are connected to the switch storage spaces from the inside of the first case member 20. It attaches to 28a-28e. Then, the seal portions 50c to 54c are pushed into the wall surfaces 29a to 29e until they contact the step. In this state, by attaching the contact members 55 to 59 to the inner side surfaces of the seal portions 50c to 54c, the seal portions 50c to 54c are brought into close contact with the wall surfaces 29a to 29e, and the switch openings 27a to 27e are sealed. Here, since the wall surfaces 29a to 29e are provided with steps, the switch operation members 50 to 54 can be easily connected to the switch storage spaces 28a to 28a simply by bringing the seal portions 50c to 54c of the switch operation members 50 to 54 into contact with the steps. Can be attached to 28e.
[0043]
  As shown in FIG. 2, a water depth display unit 5 and a reel control unit 30 connected to the water depth display unit 5 and the operation key unit 6 are arranged in the upper part of the counter case 4. The reel control unit 30 includes a plurality of electrical components 35 including a microcomputer including a CPU, a RAM, a ROM, an I / O interface, and the like disposed in the counter case 4 and a circuit board 36 for connecting the plurality of electrical components 35. Including. The reel control unit 30 executes various control operations such as display control of the water depth display unit 5 and motor drive control according to the control program.
[0044]
  A PWM drive circuit 31 that performs PWM drive of the motor 12 is disposed in the lower part of the counter case 4. The PWM drive circuit 31 is disposed in the protruding portion 21 c of the second case member 21. The PWM drive circuit 31 includes a plurality of electrical components 33 including FETs 32 as drive elements for driving the motor 12 and a circuit board 34 for connecting the plurality of electrical components 33. The PWM drive circuit 31 is connected to the reel control unit 30 by wiring. The FET 32 is screwed to the protruding portion 21 c of the second case member 21 and is cooled by the second case member 21. The PWM drive circuit 31 variably drives the motor 12 with the duty ratio controlled by the reel control unit 30.
[0045]
  The circuit board 36 of the reel control unit 30 is fixed to the second case member 21 with screws, and the circuit board 34 of the PWM drive circuit 31 is fixed to the second case member 21 together with the lid member 24 with screws. Yes. In this case, since all the circuit boards 34 and 36 accommodated in the counter case 4 are mounted on the second case member 21, various types of circuit boards 34 and 36 are mounted on the second case member 21. Can be tested. Only the second case member 21 on which the circuit board that has passed the test is attached can be attached to the first case member 20. For this reason, the number of assembling steps can be reduced, and the test failure product can be easily corrected, thereby reducing the cost.
[0046]
  Further, as shown in FIG. 3, a buzzer 40 for outputting various alarm sounds and a spool sensor 41 for detecting the rotation direction and speed of the spool are also arranged in the lower part of the counter case 4.
[0047]
  As shown in FIGS. 3 and 4, the buzzer 40 is composed of a piezoelectric element 40 a mounted on the top surface of the lid member 23, and a slight gap is formed between the buzzer 40 and the lid member 23 having a concave top surface. The buzzer 40 is connected to the reel control unit 30, and vibrates the lid member 23 through the space formed in the gap by vibrating the piezoelectric element 40a, and transmits sound to the outside. Here, since the thin cover member 23 made of a synthetic resin is provided on the second case member 21 and the piezoelectric element 40a is disposed there, the buzzer 40 can be used even if the counter case 4 is closed with the second case member 21 made of conductive metal. Works reliably.
[0048]
  The spool sensor 41 is composed of two reed switches 41a and 41b arranged side by side in the front-rear direction. The reed switches 41 a and 41 b are connected to the reel control unit 30 and are disposed facing the lid member 24. The reed switches 41a and 41b detect the two magnets 14c attached to the magnet wheel 14. The number of rotations of the spool 10 can be detected by counting the detection pulses by the reel control unit 30. Further, the rotation direction of the spool 10 can be detected depending on which of the reed switches 41a and 41b has issued the detection pulse first. Here, since the reed switches 41a and 41b are disposed on the synthetic resin lid member 24, the magnet 14c of the magnet wheel 14 can be reliably detected without being affected by the second case member 21 made of conductive metal.
[0049]
  In the electric reel having such a configuration, when the fishing line is fed out, the clutch is turned off by the operation lever 11, the spool 10 is freely rotated, and the fishing line is fed out by the weight of the weight attached to the fishing line. When the fishing line is fed out, the spool 10 is rotated, and the water depth display of the water depth display unit 5 is changed according to the feeding amount by the detection pulse of the spool sensor 41. When the device reaches the shelf, the clutch is turned on by the operation lever 11 to stop feeding the fishing line.
[0050]
  When the fish hits, the switch SW1 and the switches SW2 and SW3 arranged on the operation key unit 6 are operated to wind up the fishing line. When the switch SW1 is operated, the duty ratio of the PWM drive circuit 31 is controlled until the reel control unit 30 reaches a desired rotation speed according to the operation, and the PWM drive circuit 31 makes the motor 12 variable at the controlled duty ratio. To drive. Further, when the switches SW2 and SW3 are operated, the motor 12 can be increased or decreased.
[0051]
  As a result, the motor 12 rises to a desired rotation speed and maintains that rotation speed. Further, the FET 32 generates heat in accordance with the load acting at the time of winding, but the air flow generated by the rotation of the spool 10 hits the second case member 21 to cool the second case member 21. As a result, the FET 32 attached to the second case member 21 is easily and reliably cooled.
[0052]
  Further, since the cylindrical seal portions 50c to 54c of the switch operating members 50 to 54 are pressed by the contact members 55 to 59 to prevent the liquid from entering from the switch openings 27a to 27e, the circuit board and the first case The counter case 4 can be reliably sealed by suppressing the deformation of the circuit board 36 as compared with the conventional technique in which the seal portion is sealed with the member.
