Description

  The present invention relates to a counter case, in particular, a display device that is provided on an upper portion of a reel body of an electric reel having a handle and an electric element on the first side and having a motor connection portion on the second side, and displays the water depth of the device. The present invention relates to an electric reel counter case in which a motor and a reel control device for controlling the display device are housed at least inside.

  The electric reel that rotates the spool at the time of winding with a motor has a counter case for displaying the water depth of the device provided at the upper part of the reel body. The counter case is normally sealed in a watertight manner to prevent a short circuit of the internal electric circuit. In the counter case, a reel control circuit for displaying the water depth of the device and controlling the electric motor is housed. The reel control circuit is equipped with a microcomputer including a CPU, a memory, an I / O interface, and the like. The reel control circuit is connected with various electric elements such as a liquid crystal display and its driving circuit, a water depth detection sensor, and a notification buzzer. Each of these connecting portions connected to the reel control circuit is also housed in a watertight sealed counter case.

On the other hand, a spool driving motor and various electric elements are also arranged outside the counter case. For example, connection terminals and drive circuits of conventional motors are arranged on the side opposite to the handle mounting side (second side). Further, a solenoid is disposed on the handle mounting side (first side) as an electric element for operating the clutch mechanism (see Patent Document 1). These motors and electric elements outside the counter case and the reel control circuit in the counter case are connected by wiring. Such wiring to the motor and the electric element is led out through an opening provided in the counter case. Since the amount of wiring to the motor is large, the opening is formed on the reverse side of the handle mounting side and downward on the back surface of the counter case. An electrical wiring extends through the opening to the solenoid disposed on the handle mounting side and the motor disposed on the opposite side of the handle mounting side. A cylindrical space that can be filled with a sealant having viscosity and fluidity, such as silicone rubber, is formed below the opening, and the opening is sealed by filling the space after the wiring is inserted.

  In the counter case of the electric reel, when the wiring is taken out from one opening toward the handle mounting side, the wiring to the electric element provided on the handle mounting side has to be detoured and the electric wiring becomes long. Therefore, it is conceivable to connect the electric wiring to the motor and the electric element from the two openings on the handle mounting side and the opposite side. In this case, if an opening is provided on the back surface of the counter case, a space for filling the sealant is required below the opening, so that the thickness of the counter case is increased. In order to prevent this, if an opening is provided on the side surface of the counter case, a filling space for the sealant is disposed on the side surface. When the sealing agent filling space is provided on the side surface and the bottom surface in this way, the sealing agent has fluidity before curing. There is a possibility that the sealant flows out of the space and cannot be sealed well. For example, if the two filling spaces are filled with the bottom surface facing upward, the sealing agent may flow out from the filling spaces provided on the side surfaces. For this reason, it is necessary to fill the sealing agent in one filling space and then cure with warm air, and then fill the other filling space with the sealing agent and cure. If openings are provided on separate surfaces in order to reduce the thickness as described above, the filling step and the curing acceleration step using hot air must be performed in two stages, and the sealing step becomes complicated.
