Abstract

(57) [Summary] [Purpose] The present invention is intended to protect a sensor disposed in a watch case from external shocks. [Structure] A sensor protection pipe 13 having a sensor 14 disposed thereon is fixed to a through hole 11 formed in the side wall of a watch case 10 made of resin, and the outer surface of the sensor protection pipe 13 is covered with a decorative nameplate 19. . [Effect] The sensor can be protected even if strong impact or pressure is applied to the watch case.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention incorporates a sensor for measuring pressure, temperature, etc. into a watch case made of resin. This concerns the mounting structure of the

0002

[Conventional technology]

As a prior art, there is Japanese Utility Model Application No. 63-98583, which is shown in a cross section of the main part in FIG. child In this structure, a through hole 3 is formed on the side surface of the watch case 2, and a packing 4 is inserted into the through hole 3. The sensor 1 is fixed therethrough. In addition, 5 is arranged on the top surface of the watch case 2. 6 is a back cover disposed on the bottom surface of the watch case 2.

0003

[Problem that the idea aims to solve]

However, in this conventional structure, the sensor is placed in the through hole of the watch case. Because it is fixed through the packing, strong force is applied to the watch case from the outside. In such cases, force may be applied to the sensor, causing measurement errors or even causing it to break. Ta. As a result, the sensor that measures water depth has the potential to cause damage to the diver's life. There it was.

0004 In addition, with the diversification of designs in recent years, many watch cases are made of resin. A sensor for measuring water depth is installed in a watch case made of this resin. However, especially for hyperbaric diver watches, the watch case is exposed to high pressure. When the watch case is slightly deformed, the sensor is also deformed by , similar to the above, measurement errors and failures of the sensor may occur.

[0005] The purpose of this invention is to solve the above problems and to strengthen the watch case made of resin from the outside. Provides a sensor mounting structure that protects the sensor even when strong forces are applied. It's there.

[0006]

[Means to solve the problem]

The configuration of this invention is that a sensor is installed on the side of the watch case to measure pressure, temperature, etc. In the structure of the watch that incorporates the sensor, the sensor is housed on the side wall of the watch case made of resin. A through hole is provided for installing a protection pipe, and a sensor is installed in the through hole. Insert and fix the metal sensor protection pipe to be installed into the sensor protection pipe. In addition to arranging the sensor, the outer surface of the sensor protection pipe is covered with a decorative name plate. It is characterized by this.

[0007]

【Example】

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Figure 1 shows how the sensors are arranged. FIG. 3 is a sectional view of a main part of the installed watch case.

[0008] The watch case 10 made of resin has a through hole 11 that penetrates inside from the side wall. , the through hole 11 has a stepped portion 12 approximately in the middle thereof. Two stages in the through hole 11? The sensor protection pipe 13 made of metal is fixed by means of press-fitting, welding, etc. Ru. At this time, the large-diameter lower surface of the sensor protection pipe 13 is attached to the stepped portion 12 of the watch case 10. are fixed in contact with each other, and waterproofness is also ensured.

[0009] Next, a packing 17 is placed on the stepped portion 16 on the inner and lower surface of the large diameter portion of the sensor protection pipe 13. The sensor has a packing 18 attached to the circumferential groove 15 formed on the outer periphery of the sensor 14. The sensor 14 is installed inside the sensor protection pipe 13. The packing 17 and The packing 18 is used to waterproof the area around the sensor 14 and to protect the watch case 10 from the outside. It has a function to protect the sensor 14 in case of impact. Also, the sensor - The protective pipe 13 also protects the sensor 14 from impact, pressure, etc. applied to the watch case 10. It has the function of protecting.

0010 Next, a decorative name plate is placed on the outer surface of the sensor 14 and the sensor protection pipe 13. 19 is fixed to the sensor protection pipe 13 by means such as screws or welding. This outfit A plurality of through holes 20 are formed in the decorative nameplate 19 at positions corresponding to the measurement parts of the sensor 14. has been completed. 21 is a flexible printed circuit board with sensor 14 and module A circuit board (not shown) is connected to the circuit board (not shown).

[0011] In the above embodiment, the sensor protection pipe 13 is press-fitted into the watch case 10. Although the sensor was fixed by adhesive, welding, etc., when molding the watch case 10, the sensor was kept in the mold. Needless to say, it is also possible to perform insert molding by fixing the protective pipe 13. .

0012

[Effect of the idea]

As explained above, according to the present invention, in the through hole in the side wall of the watch case made of resin, A sensor protection pipe with a sensor installed is attached, so the watch case cannot be accessed from the outside. Even if a strong force, shock, or pressure is applied to the It is possible to reliably protect the equipment without causing any damage to the equipment. Also, place 2 around the sensor. Waterproofing is ensured as it is equipped with two gaskets.
