Description

    The present invention relates to a charging stand that charges a built-in secondary battery of a small communication terminal device through a relay adapter.

    In charging a small communication terminal device, a power supply adapter output is conventionally supplied by attaching a cable with a connector directly to the micro USB connector of the terminal device body, or a model called a cradle paired with a small communication terminal device By placing the small communication terminal device main body on the dedicated charging stand, charging is performed by contacting and supplying power to the charging dedicated electrode provided on the end surface of the small communication terminal device main body and the electrode on the charging stand side that is paired with the electrode. Devices that make it possible are known.

    However, the task of directly attaching a cable with a small connector to a small communication terminal device is a difficult operation unless it gets used to positioning accuracy and front / back judgment, and is an obstacle to the expansion of the user base. The terminal position must be accurately positioned, and the cradle must have a receiving shape that follows the external shape of the small communication terminal device. If the small communication device is changed, it cannot be used if the external shape or terminal position is different. There was an economic and environmental problem saying that a cradle had to be obtained.

    In recent years, small-sized portable communication terminals, in particular, tend to be more compact with an emphasis on portability. For this reason, for charging wired data communication with external information devices such as personal computers without placing / equipping dedicated charging electrodes on the end face of the main body. There is a tendency that a small connector called a micro USB connector or a Lightning connector is also used for charging. (Hereinafter, small data communication connectors called micro USB connectors and Lightning connectors are generically referred to as small communication connectors in this specification.)

    However, these small communication connectors used in portable communication terminals, in particular, have very small fitting holes themselves, so precise positioning is required for fitting and insertion. It is difficult to fit the connector with a rough operation such as just placing it, so it is necessary to fit the connector directly by a human hand. There are many users who are unfamiliar with weak visual acuity, and it is very difficult for such users to install small connectors for communication that are necessary almost every day, and it is difficult to distinguish between front and back, it is very difficult, puzzled and psychological burden It is a hindrance to market expansion.

In addition, many portable communication terminal devices are equipped with a precise small connector for communication so that the fitting hole is exposed on the side of the main body, making it easy for dust to enter and for charging almost every day. There are also problems that contact failure due to contact wear or the like occurs by repeatedly attaching and detaching, and that inadvertent force may be directly applied to precision parts during insertion and removal.

Furthermore, the external appearances of these portable communication terminal devices differ in shape and size from model to model, and the mounting position of the small communication connector differs from model to model with respect to the portable communication terminal device body. Even if a cradle device for charging that can be precisely positioned by holding the external shape as shown in some of the mobile phones shown is required, a dedicated cradle device that differs for each model is required, and the model is changed. There are also environmental and economic challenges that sometimes require an old cradle device and additional expense for another new cradle device.

The present invention addresses such many problems by attaching a small relay adapter that can be fitted to the small communication connector of the communication terminal device body without any modification to the communication terminal device body. The charging electrode is exposed on the opposite side of the relay adapter from the small communication connector, and the cradle that receives the communication terminal device body is fitted with a relatively long length in the length direction substantially equal to the width of the relay adapter. A hole is provided so that the relay adapter can be fitted with a degree of freedom in the length direction, and positive and negative electrodes that are long in the length direction of the fitting hole are provided in parallel to provide an electrode on the relay adapter side. By enabling contact power supply to the user, the user can place the mobile terminal device body in the approximate hole position on the cradle with the small communication connector on the bottom, and contact power can be supplied by simply placing it. Do not depend on the model of It is intended to provide a charging system of the mobile terminal device that can be used with confidence in a simple.

The relay adapter and cradle device related to the present invention are small and simple relay adapters in the small communication terminal device main body without any modification to the small communication terminal device main body mass-produced by many manufacturers and communication companies. Once attached, the power supply electrode can be connected by placing the main body of the small communication terminal device on the cradle in the approximate position with the top and bottom and front and back together when charging without worrying about the front and back sides and position of the connector. Therefore, it is easy to understand and can be used with peace of mind even for users who are unfamiliar with the handling of communication terminal devices.

In addition, the relay adapter does not require a data terminal and the number of terminals is only two poles of positive and negative power supply compared to a small connector for communication, so the electrode area can be widened, and it is easy to take a structure that is advantageous for problems such as poor contact and fitting. Since it is too loose, no charging force is applied between the small communication terminal device and the cradle, and reliability is ensured.

Furthermore, by extending the fitting hole on the cradle side, it becomes possible to fit regardless of the left and right mounting positions of the small communication connector with respect to the main body of the portable communication terminal device. It can be shared by a wide range of devices, including terminals.

In addition, even if the small communication connector equipped in the portable communication terminal device is a different type of connector such as a micro USB connector or a lightning connector, the connector side of the small and simple relay adapter has a connector shape of the corresponding standard. Even if the micro USB connector is mounted on the main body only when it is replaced, the positive / negative polarity is correct if a relay adapter that reverses the connection between the USB connector of the relay adapter and the opposite electrode is used. Since power is supplied, the cradle side has both extremely high economic efficiency and environmental friendliness that it can be used in common with many small communication terminal devices.

It is a system diagram which shows the Example of the portable communication terminal device main body, the adapter for relay based on this invention, and a cradle apparatus. It is an enlarged view of the adapter for relays concerning the present invention. It is sectional drawing of the fitting state of the portable communication terminal device main body, the adapter for relay, and the cradle device according to the present invention. It is a cross-sectional perspective view by the side of the cradle apparatus which concerns on this invention. It is sectional drawing of another fitting state of the portable communication terminal device main body, the relay adapter, and the cradle device according to the present invention.

As shown in FIGS. 1 and 2, the relay adapter 10 that can be attached to a small communication connector (receptacle) (not shown) of the mobile communication terminal device 1 has an end surface opposite to the connector portion (plug) 13. It has exposed terminals 11 and 12 of conductive material.

On the other hand, a slit 50 is provided in the lateral direction on the top surface of the cradle device 20 that holds the portable communication terminal device so that the relay adapter is on the bottom surface with the relay adapter attached. As shown in FIGS. 3 and 4, elongated electrodes 21 and 22 are attached to the inside of the slit so as to be independently biased upward by spring members 25 and 26 in parallel to the slit direction.

The electrodes 21 and 22 are connected to a connector 28 that can receive power from an external AC adapter or the like by a conductive member (not shown).

When the relay adapter 10 is inserted into the mobile communication terminal device 1 at the position of the slit 50 of the cradle device 20 configured as described above, the electrode 11 of the relay adapter is connected to the cradle side electrode 21 as shown in FIG. Then, the electrode 12 can contact the electrode 22 with the weight of the mobile communication terminal device, respectively, and can supply the charging power received by the connector 28 to the mobile communication terminal device.

In the system configured as described above, the portion to be fitted for charging has a larger outer shape on the electrode side of the relay adapter as compared with the small connector fitting portion for communication, and the contact portions are those of 11 and 12 in FIG. Since it can be removed as widely as an electrode, rotation and displacement in the plane XY direction are relatively allowed, so the gap between the fitting members can be increased, so there is almost no friction between the outer shape of the relay adapter and the slit hole 50. Even with its own weight, it can be sufficiently fitted and the electrodes can be contacted. In addition, the cradle-side slit that receives the outer shape of the bottom surface of the relay adapter is oblong and has a sufficient degree of freedom in the horizontal direction. If it is slid rearward at that position, the relay adapter falls into the cradle-side slit, making it possible to fit and make charging much easier.

In addition, it is not necessary to hold and regulate the side surface of the mobile communication terminal device, and even if the small communication connector is located on either the left or right side of the main body, it can be fitted as long as the relay adapter comes within the slit range. Therefore, the cradle device does not need to be replaced even if the model of the mobile communication terminal device changes.

Further, as shown in FIGS. 3 and 5, by changing the height of the two contacts on the bottom surface of the relay adapter and changing the corresponding two contact heights on the cradle side to be opposite to each other, the user can When the mobile communication terminal device is set upside down on the cradle, the contacts on one side do not come into contact and can not be energized, so it is possible to prevent damage to the device without providing a protection circuit for the device. Such a reverse misconnection prevention function is not limited to a method in which the height direction is different. For example, a known method may be used in which one electrode cross section has a convex shape and the other has a concave shape.
