2 contacts the charging terminals 15 and 16 of the charger 13, and the electronic device 10
The charging terminals 15 and 16 of the charger 13 sink due to their own weight, and the structure is such that a reliable contact state is maintained.

[Problems to be Solved by the Invention] In the above-described conventional connection structure between the electronic device and the charger, the fitting recess provided on the charger side is formed to correspond to the end surface shape of the electronic device. Since the structure is such that the end face of the device is matched with the fitting recess on the charger side for connection, the user must pay attention to the directionality between the electronic device and the charger when connecting, It had a problem of poor sex.

In addition, in order to have multiple directions of fitting between the electronic device and the charger, the bottom shape of the electronic device needs to be line-symmetrical or point-symmetrical, which is a drawback due to design restrictions. It was

The present invention has been made in order to solve the above-mentioned problems, and it is possible to connect an electronic device to a charger in an arbitrary direction, and to connect the electronic device no matter how the end face shape is designed. The purpose of the present invention is to provide a connection structure for a portable electronic device and a charger.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a connection structure formed on an end surface of an electronic device and an output part of a charger,
A circular fitting recess is formed on the end surface of the electronic device, and a planar first contact terminal is provided at the center of the fitting recess, and the fitting recess is concentric with the first contact terminal as the center. A ring-plate-shaped second contact terminal having a predetermined width is provided on the one hand, while a circular recess having a diameter larger than the maximum outer diameter of the end face of the electronic device is formed on the output part of the charger. , A fitting convex portion corresponding to the fitting concave portion of the electronic device is formed in the concave portion, and a first charging terminal is provided at the center of the fitting convex portion, and the electronic device is centered around the terminal. The second charging terminal is provided at the same distance as the radius of the second contact terminal.

[Operation] In the connection structure of the electronic device and the charger of the present invention described above,
The fitting recess provided on the electronic device and the fitting projection of the charger fitted to the electronic device are circular, and the electronic device is placed in the circular recess of the charger, so that the electronic device can be installed in any direction. The connected state can be realized, and there is no restriction on the design of the end shape of the electronic device.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a connection structure between an electronic device and a charger according to an embodiment of the present invention.

In the drawings, reference numeral 1 denotes an electronic device, in which a circular fitting recess 2 is formed in the center of the bottom surface, and a flat first contact terminal 3 is provided in the center thereof. In addition, the first contact terminal 3
A ring plate-shaped second contact terminal 4 having a predetermined width is provided concentrically with the fitting recess 2 around the center. Of these first and second contact terminals 3 and 4, one has the polarity of an anode and the other has a polarity of a cathode.

Further, in the drawing, 5 is a charger, and a concave portion 6 having a diameter slightly larger than the maximum outer diameter of the bottom surface of the electronic device 1 is provided on the upper surface.
And a fitting convex portion 7 is concentrically provided in the concave portion 6. Here, the fitting convex portion 7 has a size and shape corresponding to the fitting concave portion 2 in the electronic device 1.

A first charging terminal 8 corresponding to the first contact terminal 3 of the electronic device 1 is provided at the center of the fitting convex portion 7,
Further, a first charging terminal 9 is provided at the same distance as the radius of the second contact terminal 4 of the electronic device 1 with the terminal 8 as the center. These charging terminals 8 and 9 have a structure that can be slid up and down by a coil spring or the like, and when the electronic device 1 is placed on the charger 5, the contact terminals 3 and 4 of the electronic device 1 are charged. The electronic device 1 is contacted with the charging terminals 8 and 9 of the container 5.
Due to its own weight, the charging terminals 8 and 9 of the charger 5 sink and the structure is such that a reliable connection state is maintained.

According to the connection structure of the electronic device and the charger described above, the electronic device 1 is placed in the recess 6 of the charger 5 so that the contact terminals 3 and 4 come into contact with the charging terminals 8 and 9 of the charger 5. The connection state can be realized simply by arranging it without considering the directionality. The bottom shape of the electronic device 1 can be designed without any restrictions.

It should be noted that the present invention is not limited to the above-described embodiments, and for example, the structure on the electronic device side described above may be provided on the end surface other than the bottom surface of the electronic device.

[Effects of the Invention] As described above, according to the present invention, by providing the contact terminals of the electronic device in the center of the bottom surface and the concentric circles, and further by making the fitting concave and convex portions of the electronic device and the charger circular, Remove the orientation of placing the device on the charger,
° It can be charged in any direction by placing it on the charger,
This has the effect of improving the operability for the user.

Further, since the concave portion for arranging the electronic device in the charger is circular, the end face shape of the electronic device can be supported, and there is an effect that the degree of freedom in design is increased.
