Abstract

PROBLEM TO BE SOLVED: To facilitate the fixing of a control terminal connecting to a control board by using a machine screw A to tighten a connection metallic fixture via a battery terminal connecting to a battery and using a machine screw B to tighten the metallic fixture via the connection terminal connecting to the control board. SOLUTION: A connection metallic fixture 15 has a through-thread to an inner cylinder formed by outsert or insert forming and whose both end faces are faced to a control board 6 and a battery chamber 8 while being penetrated through a wall 9. A machine screw A16 is tightened to the metallic fixture 15 via a battery terminal 17 connecting to the battery 14. A machine screw B18 is tightened to the metallic fixture 15 via a connection terminal 19 connecting to the control board 6 together with a seal agent 20. Thus, while the machine screw A16 is tightened to the metallic fixture 15 via the battery terminal 17 connecting to the battery 14, the machine screw B18 is fixed to the metallic fixture 15 without soldering the terminal 19 connecting to the board 6. As a result, the locking of the terminal 19 to the metallic fixture 15 is facilitated and a danger that a wall 9 around the metallic fixture 15 is not thermally molten in mistake during soldering is avoided.

BEST MODE FOR CARRYING OUT THE INVENTION A first means of the present invention is to provide a control board chamber in which a control board is provided inside a remote control case, and a battery inside a control board chamber, which is separated from the control board chamber by a wall and covered with a battery lid. Battery chamber, and a connection fitting with a through screw in the inner cylinder formed by outsert or insert molding so that both end surfaces can be seen through the wall into the control board room and the battery room, and the battery connected to the connection fitting to the battery A screw A tightened via a terminal and a screw B tightened with a screw via a connection terminal connected to the control board are similarly provided to the connection fitting.

The second means is that the connecting fitting is screwed through a battery terminal connected to a battery, and a screw C is screwed through the connecting terminal connected to the control board. The metal fitting is provided in surface contact with the other surface.

According to the first means, the cordless bath remote control device of the present invention is fixed to the connection fitting by fixing the locking of the connection terminal connected to the control board with the screw B instead of fixing with the solder. It facilitates the work of locking the connection terminals and eliminates the risk of water accidentally melting the walls near the connection fittings by heat during soldering and invading the control board from the outside.

According to the second means, the cordless bath remote control device of the present invention is such that the metal fitting is press-fitted into the screw C which is screwed to the connecting metal fitting through the battery terminal, through the connecting terminal connected to the control board. This prevents the screw C from loosening with the connection fitting and facilitates the work of locking the connection terminal to the connection fitting.
