Metalmade pins 20a- 20d are provided to the case 17 and are in contact respectively with contact parts 8a, 9a, 13b, 14b of the battery case 1 to attain electric continuity. Further, a earphone plug 24a of an earphone 24 is inserted to an earphone jack 10 provided to the battery case 1. Then the battery is replaced easily and defective waterproofness of the earphone 24 is avoided.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a battery case that supplies energy to the radio receiver in a radio wristwatch in which a radio receiver and a clock are housed in one wristwatch case. is provided separately, an earphone is attached to the battery case side, and via the electrical connection part,
It relates to a structure that is coupled to the wristwatch body.

[Background of the invention]

In recent years, radio-equipped wristwatches have been sold that have functions other than a clock, such as a radio receiver, integrated into the clock. The problem with this watch with a radio is that the radio consumes a lot of energy, so the user needs to be able to easily replace the battery. There is a problem that sweat and dirt get into the earphone jack and corrode the elastic metal material that provides electrical continuity to the earphone jack. Solving these problems is
This is an issue in the commercialization of radio wristwatches.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a wristwatch with a radio that allows the user to easily replace the battery and does not cause waterproofing failure of the earphone jack.

[Structure of the invention]

In the present invention, the power source for the radio is provided as a separate battery case, and the battery case is provided with an earphone jack for attaching an earphone. When you want to listen to the radio, you attach the battery case to the main body of the radio wristwatch, and electrical continuity is established by connecting The feature is that it is carried out through the section.
