[Detailed Description of the Invention] The invention relates to an external contact device (hereinafter referred to as a connector) provided on the watch case of a portable watch. It provides a connector for inputting and outputting electric power. As a usage example, external power supply connector? It can be used to supply audio and visual values to the mobile watch, or it can be transmitted from an external device to the mobile watch using the connector R, and can be emitted and displayed on the nozzle heater, liquid crystal panel, etc. inside the mobile watch. Possible ways to do this are to However, despite these possible useful uses, what about this type of connector? #A A design and size that fits the hour hand and watch are required, and miniaturization is generally considered to be safe, so there is no loss of operability, contact stability, durability, watertightness as a portable watch, load resistance, dust resistance,
It is difficult to satisfy the various qualities of wear-resistant parts, and no effective invention has been found today. The present invention was invented with the use in the above-mentioned field of use or its applied field in mind, and its aim is to satisfy the above-mentioned qualities without impairing the operation of a small connector for mobile watches. be. The present invention will be explained in detail below based on the above.

FIG. 1 is a perspective view showing the configuration of the present invention, and shows the state before the connector is connected. 1 is the mobile watch case, 2 is the jack, and 6 is the cord connected to part of the external tuner?
It is a plug that connects to the watch case, whether it is a TV signal, a radio signal, etc. On the ridged upper surface of the mobile watch case 1, an external electrical contact terminal 2 is held in a watertight manner with an insulating material 2b.
The jack 2 is fixed by adhesive, bra-straight, fitting plus contact, or the like. As the material for the insulating material 2b, plastic resins conventionally used for exterior parts of mobile watches, such as polyarylate, acetal, tetrafluoroethylene, and dioxydiphenylglopancarbonate, are excellent in quality and surface area. ing.

Abrasion resistance can be improved by adding glass fiber to bamboo. Alternatively, inorganic glass may also be considered. -1:
Furthermore, if the portable watch case 1 is made of a nonconductor such as plastic, the insulating material 2bi may be omitted. Gold and platinum, which have good electrical conductivity and excellent corrosion resistance, are used as materials for the external electrical contact terminals 2a, but generally brass, phosphor bronze, etc. are plated with gold, platinum, etc. Next, the guiding and fixing part of the plug will be explained. On the side of the gun of the portable watch case 1, three FF grooves 1a are formed by leaving 7 lunges 1br parallel to the upper surface of the scissors and the insulating material 2b. The plug 3 has a flange 1b for guiding in the left and right (horizontal) direction of the guide groove 1a7.
As guidance for both the upper and lower sides of the meeting, the jack portion 2 is connected and removed in the direction of the arrow in FIG.

FIG. 2 is a cross-sectional view of the bottom of the mobile watch case shown in FIG. The insulating material 2bμ formed on the upper surface of the ridges of the portable watch case 1 is constructed so that the protrusion or depression from the upper surface of the ridges is uniform. The outer S electrical contact terminal 2a is connected to the movement 4 through a conduction spring 4ai. In addition, in order to prevent a short circuit with the mobile watch case 1, the external electrical contact terminal 2a is fitted into the insulating material 2b as described above in the case of the Kinpo case.
Alternatively, it is fixed by fitting plus bonding, and the insulating material 2b
is firmly fixed to the stepped portion provided on the ridged upper surface of the mobile watch case 11 by a contacting method. The portable watch case and jack configured in this manner are guided and fixed by the guiding and fixing part of the portable watch case of the plug, as described above. FIG. 6 is a sectional view of a main part showing the viewing state r. The electrical contact member 3b of the plug and the external chamber/gas contact terminal 2a of the jack are connected. Similarly, the electrical contact member of the plug is inserted into the mobile watch case from the surface of the jack to the tip. In order to ensure continuity, it is preferable for the electrical contact member 2a of the plug to protrude slightly beyond the insulating material 2b so that they all ride in the same direction. Also, with this configuration, the electrical contacts of the plug and jack can be connected by rubbing together. It is also expected to have the effect of removing the oxidized liquid III produced on the surface every time the plug is removed, improving contact stability. In the case of a malfunction, the electric power or electric power input by the external cord 6C of the plug is connected to the electric contact member 3b.
The signal is transmitted to the external contact terminal 2a of the jack through the terminal.

It is further sent to the movement 4 via the quadratic spring Aak, and appears as a power supply or as an output to the display section 4b such as a liquid crystal panel. On the other hand, keyboards etc. installed on mobile watches (
(not shown), the devices connected to the external cord of the plug via the above-mentioned pick-up route, 1Ptl, t, and 1g are sent to the microcomputer, and the calculation results are sent to the movement via the above-mentioned signal transmission route. Naturally, it is also assumed that the sent information will be displayed on a display unit such as a liquid crystal panel.

Next, the plug portion of the connector for a portable watch according to the present invention will be explained. , FIG. 4, FIG. 5, and FIG. 6 show embodiments of the plug of the present invention. Figure 4 is a plan view of the main part, Figure 5 is a partial cross-sectional view of Figure 4, and Figure 6 is a cross-sectional view taken along line AA' in Figure 5. Case body 3

are arranged in the same number and at the same pitch as the external electrical contact terminals 2a of the jack. Further, elasticity is added to absorb the protruding variation from the insulating material of the external electrical contact terminal of the jack, and the structure is configured to improve the contact stability rSi. ! ! In order to exhibit the elasticity of the electrical contact member 3b, the case body 6a includes:
A cutout hole is set corresponding to the electrical contact member 3b.

An external cord 6C enters from one end of the case body 3a and is soldered to the pattern 3e on the board. The external cord 3C and the electrical contact member 3b are connected through the pattern on the board. The other end of the external cord is connected to a power source, 10H alarm, etc. , 5 and 6, 3g is a case fixing member. One end is fixed to the case body by driving a pin 31 or gluing, and the rounded portion for position regulation is further supported by the case body.

A spring is applied to the free end, and the repulsive force of the spring applies a pressing force to the flange portion 1b of the portable watch case, thereby fixing the plug to the jack portion.

Furthermore, in order to increase the fixing force and layering feeling (click feeling)', side pins sh2 and side pins 3 are installed on the guide surface 3j.
By dropping it into the engagement hole 1C provided in the guide groove 1a of the watch case at the complete mounting position, the fixing force and mounting feeling are increased. Also, is it a good feeling? In addition, when installing the device, the case near the clip pin 3h will be deformed,
Is the wall side 3ni thick to make it easier to deform? Possible measures include making it thinner or adding 7 to the notch 6. The side pin 3h is placed into the case body by driving an insert into the case body. In addition, 3j is the guide surface in the left and right direction (horizontal direction) when the plug is iron layered, and 3 is a certain same figure in the vertical direction. Slide. On the inner surface 3 of the mobile watch case, there is a musketeer surface of the mobile watch case and a tray plug on the top surface of the jack that slides when the plug is attached or removed. The aforementioned mobile watch case fixing member 6g comes into contact with the lower surface of the flange portion 1b of the mobile watch case,
While supine deformation occurs, the flange portion 1b slides in the downward concave t as the plug is attached and detached. At this time, the electrical contact member 3b undergoes elastic deformation in the vertical direction. Mobile watch case fixing member 3
The upper part of the deer is separated at the free end of g. Therefore, if the case is constantly provided with soil +31r, the above-mentioned force can be prevented. Top lid 3
