Description

[Detailed description of the invention] (1) Purpose of the invention (industrial application field) This invention relates to a radio-controlled lock card used to operate a radio-controlled lock.

(Prior art and issues to be solved) Radio-controlled locks, which have a built-in power supply and transmitter circuit and operate the lock using radio waves emitted, have recently become more popular as small, thin button-shaped batteries become more popular. A member for operating a lock (called a card) is also becoming widely used because it can be formed into a thin card shape.

Such small batteries are usually formed into a thin button shape, with one side having a negative pole and the other side usually having a positive pole that covers the surrounding area. When this is installed in a card, the terminals on the card body side usually come into contact with each pole from the top and bottom of the battery.

However, it is preferable for the card itself to be made as thin as possible to make it convenient to carry, so if the terminals are configured to contact the battery from above and below, as described above, the overall thickness will increase accordingly. Portability will be a problem.

The present invention has been made in order to cope with such a situation, and an object of the present invention is to provide a radio-controlled lock card that has a built-in thin battery and can reduce the overall thickness of the card as much as possible. The purpose is to

(2) Structure of the invention (technical means for solving the problem and its function) In order to achieve the above purpose, the invention houses a circuit for operating a radio-controlled lock inside and has a removable lid on one side. In the radio-controlled lock card having a battery storage recess formed therein, a conductive contact plate is disposed on the inner surface of the lid body and contacts one pole of the battery, and the contact plate is provided with a conductive contact plate that contacts the circuit side terminal. When a contacting protrusion is provided, at least two circuit-side terminals are exposed in the battery housing recess, and a battery is stored in the recess, at least one circuit-side terminal contacts the protrusion, and at least one other circuit-side terminal contacts the protrusion. The circuit-side terminals are arranged at positions that abut the peripheral hanging portions of the other pole of the battery.

With this configuration, it is possible to reduce the thickness of this type of radio-controlled lock card.

(Explanation of the embodiment) Fig. 1 is an exploded perspective view of a radio-controlled lock card showing an embodiment of the present invention, and the reference numeral 1 is a main body containing a radio wave emitting/receiving circuit. Although push buttons and the like are provided, these are omitted because they are not directly related to the present invention.

One end of the main body 1 is formed with a recess 1b into which a battery serving as a power source is installed, and a plurality of (four in the illustrated case) a recess 1b is formed between the recess and the part having the circuit.
A groove 1a is formed.

These grooves have terminals 4a, 4b, 4c, 4, respectively.
d is attached. Each terminal has the same structure, and as shown in Fig. 3, the circuit side end 4e, etc. is fixed to the case 4', and the terminal piece 4a, etc. is attached to the end by means of a spring 3, so that it can freely protrude and retract from the case 4'. It has been installed and configured.

The recess 1b into which the battery is installed has a lid 7 that can be slid on and removed from the main body, and conductive elastic contact plates 5, 5 made of stainless steel or the like are integrally attached to the inner surface of the lid 7. . Further, each contact plate 5 has a notch formed therein with a roughly U-shaped elastic piece 5b, and this part can be elastically displaced separately from the main body of the contact plate 5, so that the contact plate is always It is maintained so that it protrudes beyond the main body.

Further, each contact plate 5 has a protrusion 5a at a position facing the two terminals 4c and 4d arranged in the center of the groove 1a, as shown in the figure, when the contact plate 5 is attached to the main body. 5a is provided.

As already mentioned, the battery 2 is formed in a disk shape as a whole, as shown in FIG.
A negative electrode 2b is disposed on one side of the electrode, and a positive electrode 2a is disposed so as to cover the periphery of the negative electrode 2b on the other side.

With such a configuration, the recess 1
When the battery 2 is placed on the battery 2 with the negative pole facing upward as shown in the figure, and the lid 7 is attached to the main body side with the contact plate 5 facing inside, as shown in FIG. The negative electrode 2b of the battery contacts the terminals 4c and 4d via the elastic piece 5b and the protrusion 5a of the contact plate 5, and the terminals 4a and 4b contact the positive electrode 2 of each battery 2.
It comes into contact with the peripheral hanging part of a.

Therefore, these terminals 4a to 4d are connected to the wiring member 6.
The card can be activated by connecting it accordingly.

(3) Effects of the invention As explained above, according to the invention, in a radio-controlled lock card equipped with a button-shaped battery, when the terminal on the circuit side is brought into contact with both poles of the battery, one pole is connected to the battery. The other pole of the conductive member provided on the lid of the storage compartment was configured to complete an electrical connection using the surrounding area of the battery, so in order to connect the battery and the operating circuit, the card was connected to the conductive member. Since no special member that increases the thickness is required, the overall thickness of the card can be made thin, which has a significant effect on improving portability.
