Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a connection structure between an electronic device such as a cordless telephone and a charger for charging the electronic device by placing the electronic device on the top, particularly from the top of the charger of the electronic device. The present invention relates to a connection structure for an electronic device and a charger, which has a connection structure for the purpose of preventing falls due to slipping.

[Conventional technology]

Conventionally, this type of charger has a circular seat surface 9 and 14 on which electronic devices 7 and 12 are placed, as shown in FIGS.
And the seat surfaces 9 and 14 to be fitted inside the electronic devices 7 and 12, respectively.
It has a two-stage structure with circular protrusions 10 and 15 having a diameter slightly smaller than that of the circular protrusions. In this structure, the electronic devices 7 and 12 are placed with the electronic devices 7 and 12 placed on the chargers 8 and 13.
In order to prevent slipping and rolling down of the chargers 8 and 13 when they are impacted and tilted, the protrusion 10 of the charger 8 is increased in height as shown in FIG. We respond by increasing the depth of engagement. Further, as shown in FIG. 4, a magnet 17 and a metal plate 18 are built in each of the charger 13 and the electronic device 12 to prevent them from sliding down due to magnetic force.

[Problems to be solved by the invention]

In the conventional connection structure described above, in the case of FIG. 3, since the protrusion 10 which is the fitting portion is high, the recess 11 at the bottom of the electronic device into which the fitting portion 10 is fitted needs to be formed deeply, and the mounting space inside is controlled by this depth. It Further, the periphery of the recess 11 becomes a complete dead space, and the deeper the depth, the larger the dead space and the poorer the mounting efficiency. Further, when the electronic device 7 is attached to and detached from the charger 8 while being inclined, the protrusion 10 is high, so that it cannot be easily hooked to the inner surface of the recess 11 of the electronic device and easily connected. When the magnet 17 is used as shown in FIG. 4, the electronic device 12 is lifted. The charger 13
It is necessary to adjust the weight by inserting a weight etc. so that they will not be lifted together by the magnetic force. More electronics
In order to prevent the 12 from rolling down, a magnet 17 having a strong magnetic force is required to some extent.In today's popular magnetic cards, a magnetic card is placed on or near the charger 13. If it does, the magnetism may disappear, which is not preferable.

[Means for solving problems]

According to the present invention, in a connection structure between an electronic device and this charger, a seat surface on the charger having a shape substantially the same as the bottom surface of the electronic device and having a slightly larger area, and a rising portion provided at the edge of the seat surface. , Provided inside the rising portion, having a convex portion higher than the height of the rising portion, and a concave portion provided on the bottom surface of the electronic device fitted with the convex portion, the height of the rising portion, When the electronic device is tilted, the outer peripheral portion of the bottom surface of the electronic device is high enough to contact the rising portion, and the height of the convex portion is the inner surface of the concave portion even when the electronic device is tilted. It is possible to obtain a connection structure for an electronic device and a charger, which is characterized in that the height is so high that they do not contact each other.

〔Example〕

Next, the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of an embodiment of the present invention, and FIG. 2 is a side sectional view of FIG. The basic shape of the charger 2 has a two-step structure including a circular seat surface 3 on which the electronic device 1 is placed and a protrusion 4 that fits inside the electronic device 1, as in the conventional case. The electronic device 1 is charged by providing a charging terminal to the electronic device 1. In this case, the height of the protrusion 4 is set such that the inner surface of the recess 6 can be removed without being caught by the outer periphery of the tip of the protrusion 4 even when the electronic device 1 is tilted. Installation and removal to and from the charger 2 can be performed smoothly. Further, by providing a slight rising portion 5 on the outer periphery of the charger seat surface 3, even if the electronic device 1 is impacted and tilted, the outer peripheral portion of the bottom surface of the electronic device 1 catches on the rising portion and the charger 2 It is possible to prevent rolling caused by slipping from the electronic device 1, and to make the electronic device 1 have the same level as the falling angle when the electronic device 1 is placed on a desk or the like.

[Effect of device]

As described above, according to the present invention, the protrusion that fits into the electronic device is set to the minimum required height, and the rising portion is provided on the outer periphery of the seat surface, so that the electronic device is prevented from sliding on the charger. It is possible to prevent rolling. As a result, the depth of the recess inside the electronic device as in the conventional case can be suppressed to the necessary minimum, and the restriction of the internal mounting space can be reduced and the dead space can be reduced.

Also, since the purpose can be achieved only by the shape of the case of the charger, it is possible to reduce the number of parts without using separate parts such as conventional magnets, and there is a possibility of loss of magnetism such as magnetic cards. It can be lost.
