Description

[Detailed description of the invention] This invention was devised for the purpose of making it easier to change the lamp position depending on the design of the case and dial in a watch with a lamp provided with a lamp on the dial. It is something.

The conventional structure is as shown in FIG.

The lamp 2 is fixed to the inner frame 4 via a lamp fixing member 3, and its head, which is a light source, is exposed above the dial 1 through a notch in the dial 1, so that the time display section is illuminated. It is configured.

The lead terminals that make up the lamp circuit are connected to movement 10.
, passing through the middle frame 4 and connected to the lamp 2.

With this conventional structure, it is difficult to change the lamp mounting position due to a change in the model of the wristwatch.

In other words, in addition to the dial, which naturally has to be changed,
It is also necessary to change the shapes and dimensions of the middle frame 4 and the lamp mounting member 3.

Furthermore, if it becomes necessary to change the mounting position of the lamp 2 to be inward from the outer diameter of the movement 10, it is necessary to change not only the above two parts but also the shape of the movement 10.

In the conventional structure, changing the model of a wristwatch requires changing the shape and dimensions of many parts, which also increases manufacturing costs, lengthens production schedules, and complicates management. , which has significant drawbacks.

The present invention eliminates the limitations associated with changing wristwatch models, which is a disadvantage of the conventional structure, and makes it possible to supply a large number of wristwatch models that meet diverse market needs by taking advantage of this freedom. It is something.

The details of the present invention will be explained below.

FIG. 2 is a longitudinal sectional view of an embodiment of the present invention.

The lamp 13 has a lamp cover 1 fixed to the dial 11.
4 to the dial plate 11.

The lamp cover 14 and the dial plate 11 are fixed by adhesion, press-fitting, biting, etc., and the lamp 13 and cover 14 are fixed by press-fitting, screwing, gluing, etc.

The lamp electrode terminal 17 protrudes from the lower surface of the dial and is bent outward from the center of the lamp as shown in FIG.

On the other hand, an insulating member 18 is placed on the upper surface of the movement 15, and two lead terminals 12 are arranged on the upper surface in parallel in the radial direction from the center of the movement. It is constructed so that it can be elastically deformed.

FIG. 4 is a plan view showing the lead portion, showing two lead terminals 12a.

12b is arranged radially parallel to the movement center.

L indicates the distance from the center of the movement to the center of the lamp.

Two electrode terminals 1 of the lamp 13 fixed to the dial 11
7 has exactly the two IJs mentioned above by incorporating the dial plate.
- is disposed between the lead terminals 12a and 12b, each of which contacts and conducts with the lead terminals 12a and 12b to form a dump circuit.

At this time, the lead terminal 12 can be elastically deformed in the vertical direction, and has the effect of ensuring contact with the lamp electrode terminal 17.

Also, if you want the lamp mounting position to be outside the outer diameter of the movement 15, you can freely select the position by setting the insulating member 18 larger than the movement outer diameter, and unlike the conventional example, there are no restrictions on the lamp mounting position. It can be freely selected depending on the watch model.

In addition to the case where the lamp is attached to the dial, the present invention can also be implemented when the lamp is attached to a display board such as a parting board or a facing board.

Furthermore, the present invention can also be implemented by attaching electrical parts such as a buzzer, a display body, etc. to the dial plate instead of the lamp.

Furthermore, when the lamp mounting position changes due to a change in the model of the wristwatch, it can be freely selected between the elastically deformable distance l of the lead terminals 12a and 12b, and as in the conventional example, a large number of parts are required. There is no need to change anything.

As described above, the present invention provides two parallel lead terminals on the module and connects the lamp to these terminals, which reduces manufacturing costs, shortens manufacturing steps and schedules, and improves management when changing watch models. This contributes to the realization of simplification, etc., and its merits are very large.
