Description

  The present invention relates to a non-contact adapter and a power receiving cassette.

  Conventionally, various non-contact power feeding systems that perform non-contact power feeding from a power feeding device to a power receiving device have been proposed. In particular, in a non-contact power supply system, the practical use of charging has been widespread in recent years (for example, Patent Document 1) by placing a cordless mainly on a mobile device such as a mobile phone.

In these non-contact power supply systems that have been put into practical use, a high-frequency current is supplied to a primary coil, and electric power is supplied to an electrical device in a non-contact manner through a secondary coil using electromagnetic induction.
Because of this principle, the secondary coil cannot be stably fed unless it is installed in a location where the magnetic flux of the primary coil in the power supply area is sufficiently received. Therefore, the secondary coil must be placed almost directly above the primary coil. I must.

  By the way, since mobile devices such as notebook computers need to be charged and operated at the same time, the mobile devices must be placed in a position where the user can easily use them. However, in the form in which the secondary coil is built in the mobile device, there is a problem that the device itself is placed in the power supply area and the work is forced in an inconvenient posture.

  As a method for solving this, there is a method using a non-contact adapter with a built-in secondary coil (for example, Patent Document 1 and Patent Document 2). In this method, a non-contact adapter with a built-in secondary coil is installed in the primary coil and connected to an electrical device using a connecting wire.

As shown in FIG. 1, a non-contact power feeding device (hereinafter referred to as a power feeding device) 10 is housed and fixed in a central position on the right side of the top plate 2 in the top plate 2 of the desk 1. A power supply coil 11 and a high frequency inverter 13 (see FIG. 6) that generates a high frequency current and supplies the high frequency current to the power supply coil 11 are provided in the housing of the power supply apparatus 10.

  The power feeding coil 11 provided in the housing of the power feeding device 10 is disposed on the upper side of the housing, and the coil surface thereof is disposed in parallel with the surface 2 a of the top plate 2. When the high-frequency current from the high-frequency inverter 13 is energized, the feeding coil 11 generates an alternating magnetic flux. The alternating magnetic flux is radiated upward from the surface 2 a of the top plate 2 and located immediately above the feeding coil 11.

  Further, an arrangement position display lamp 3 made of a light emitting element such as an LED indicating the arrangement position of the power supply coil 11 is provided at the position where the power supply coil 11 of the top plate 2 is installed so as to be flush with the surface 2a. ing. The arrangement position display lamp 3 is arranged at the center position of the coil surface of the power supply coil 11 and indicates the center of the power supply coil 11 by lighting.

  A non-contact adapter 20 is placed on the top plate 2. The non-contact adapter 20 has a rectangular box-shaped housing 21, and a power receiving coil 22 that generates an induced voltage by being linked with an alternating magnetic flux generated by the power feeding coil 11 of the power feeding device 10 in the housing 21. Have.

  The power receiving coil 22 is accommodated in the cassette 23 as shown in FIGS. 3 and 5A and 5B. The cassette 23 is loaded into the cassette housing recess 24 so that it can be pulled out from the opening of the cassette housing recess 24 formed on the lower side of the front surface 21a of the housing 21. The power receiving coil 22 housed in the cassette 23 is connected to a power receiving circuit 29 (see FIG. 6) provided in the housing 21 via a lead wiring cord 25 as shown in FIGS. Yes. Based on the length of the lead wiring cord 25, the distance of the cassette 23 (the power receiving coil 22) to be pulled out from the housing 21 is determined.

On the contrary, when the cassette 23 is pulled out, the lead-out wiring cord 25 wound in the housing 21 is drawn out from the cassette housing recess 24. Further, the drawn-out wiring cord 25 that has been fed out is wound up by being pulled a little by a winding and feeding mechanism and then loosened later.

  The power receiving coil 22 housed in the cassette 23 is disposed so that its coil surface is parallel to the flat surfaces 23 b on both the upper and lower sides of the cassette 23. Therefore, when the cassette 23 is disposed on the surface 2 a on the power feeding coil 11 of the top plate 2, the coil surface of the power receiving coil 22 faces the coil surface of the power feeding coil 11 in parallel.

  When the cassette 23 is loaded in the cassette housing recess 24, the flat surface 23 b of the cassette 23 is stored so as to be parallel to the bottom surface 21 b of the housing 21. Accordingly, when the casing 21 is placed on the surface 2 a on the power feeding coil 11 of the top plate 2 with the cassette 23 loaded in the cassette housing recess 24, the coil surface of the power receiving coil 22 is the coil of the power feeding coil 11.
