携帯電話等の機器において、無接点方式電力伝送による充電が検討されている。携帯電話は、薄型化のニーズが特に強く、このニーズに答えつつ、無接点方式電力伝送による充電可能な構造を実現するには、携帯電話に内蔵される受電側コイルを極薄のものとする必要がある。また、受電側コイルには、他の部品に対し電磁波の影響を防止するために、防磁シートを貼り合わせて使用されるが、一般のコイルは巻始め端子が厚み方向に突出しているため、平坦なシート上にコイルを貼り合わせた場合、コイルの巻始め端子の突出分が余分な厚みとなって、防磁シート付きコイルを薄型化する上での障害となっている。   In devices such as mobile phones, charging by contactless power transmission is being studied. Mobile phones have particularly strong needs for thinning, and in order to realize a rechargeable structure by contactless power transmission while answering this need, the power-receiving coil built into the mobile phone must be extremely thin. There is a need. In addition, in order to prevent the influence of electromagnetic waves on other parts, the coil on the power receiving side is used by attaching a magnetic shielding sheet. However, a general coil is flat because the winding start terminal protrudes in the thickness direction. When a coil is pasted on a sheet, the protrusion of the coil winding start terminal becomes an excessive thickness, which is an obstacle to making the coil with the magnetic shielding sheet thinner.

本発明は、前記事情に鑑みてなされ、無接点方式電力伝送による充電を行うための携帯電話の受電コイルとして好適な極薄化を達成可能な防磁シート付きコイルの提供を目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coil with a magnetic shielding sheet capable of achieving ultrathinning suitable as a power receiving coil of a mobile phone for charging by contactless power transmission.

前記目的を達成するため、本発明は、防磁シートにコイルが接合された防磁シート付きコイルであって、前記防磁シートは、前記コイルの厚み方向に突出した端子が収容されるスリットを有し、前記コイルは、厚み方向に突出した端子を防磁シートのスリットに合致させた状態で防磁シートに接合されたことを特徴とする防磁シート付きコイルを提供する。   In order to achieve the above object, the present invention is a coil with a magnetic shielding sheet in which a coil is bonded to a magnetic shielding sheet, and the magnetic shielding sheet has a slit for accommodating a terminal protruding in the thickness direction of the coil, The coil provides a coil with a magnetic shielding sheet, wherein the terminal protruding in the thickness direction is joined to the magnetic shielding sheet in a state where the terminal is matched with the slit of the magnetic shielding sheet.

本発明の防磁シート付きコイルにおいて、前記コイルが、１列〜３列多層巻きのコイルであることが好ましい。   In the coil with a magnetic shielding sheet of the present invention, it is preferable that the coil is a one-row to three-row multilayer coil.

本発明の防磁シート付きコイルにおいて、前記防磁シートとコイルとが、両面テープ又は接着剤を介して接合されたことが好ましい。   In the coil with a magnetic shielding sheet of the present invention, it is preferable that the magnetic shielding sheet and the coil are bonded via a double-sided tape or an adhesive.

本発明の防磁シート付きコイルは、コイルの厚み方向に突出した端子が収容されるスリットを有する防磁シートを用い、コイルの厚み方向に突出した端子を防磁シートのスリットに合致させた状態で防磁シートにコイルを接合した構成としたので、無接点方式電力伝送による充電を行うための携帯電話の受電コイルとして好適な極薄化を達成可能な防磁シート付きコイルを提供することができる。   The coil with a magnetic shielding sheet of the present invention uses a magnetic shielding sheet having a slit in which a terminal protruding in the thickness direction of the coil is accommodated, and the magnetic shielding sheet in a state where the terminal protruding in the thickness direction of the coil is matched with the slit of the magnetic shielding sheet Since the coil is joined to the coil, it is possible to provide a coil with a magnetic shielding sheet capable of achieving ultrathinning suitable as a power receiving coil of a mobile phone for charging by contactless power transmission.

以下、本発明の実施形態について、図面を参照して説明する。
図１及び図２は、本発明の防磁シート付きコイルの第１実施形態を示し、図１は本実施形態の防磁シート付きコイル１の組立斜視図、図２は防磁シート付きコイル１の斜視図である。これらの図中、符号１は防磁シート付きコイル、２はコイル、３は防磁シート、４はスリット、５は巻始め端子、６は両面テープ（両面粘着フィルム）、７は外枠である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of a coil with a magnetic shielding sheet according to the present invention, FIG. 1 is an assembled perspective view of the coil 1 with a magnetic shielding sheet according to the present embodiment, and FIG. 2 is a perspective view of the coil 1 with a magnetic shielding sheet. It is. In these drawings, reference numeral 1 is a coil with a magnetic shielding sheet, 2 is a coil, 3 is a magnetic shielding sheet, 4 is a slit, 5 is a winding start terminal, 6 is a double-sided tape (double-sided adhesive film), and 7 is an outer frame.

本実施形態の防磁シート付きコイル１は、防磁シート３にコイル２が接合されてなり、防磁シート３は、コイル２の厚み方向に突出した巻始め端子５が収容されるスリット４を有し、またコイル２は、厚み方向に突出した巻始め端子５を防磁シート３のスリット４に合致させた状態で両面テープ６（両面粘着フィルム）を介して防磁シート３に接合されている。   The coil 1 with a magnetic shielding sheet of the present embodiment is formed by joining a coil 2 to a magnetic shielding sheet 3, and the magnetic shielding sheet 3 has a slit 4 that accommodates a winding start terminal 5 protruding in the thickness direction of the coil 2, The coil 2 is joined to the magnetic shielding sheet 3 via a double-sided tape 6 (double-sided adhesive film) in a state where the winding start terminal 5 protruding in the thickness direction is matched with the slit 4 of the magnetic shielding sheet 3.

このコイル２は、無接点方式電力伝送による充電を行うための携帯電話の受電コイルとして好適な極薄の１列〜３列多層巻きコイルである。
図３〜図５はコイル２の一例を示し、図３はコイル２の斜視図、図４は平面図、図５は側面図である。本例示において、コイル２はドーナツ状をなし、図５に示すようにコイルの厚み方向において、巻始め端子５がコイル本体から突出している。従って、このコイル２を平坦な防磁シート上に接合した場合には、巻始め端子５の厚さ分だけ、防磁シート付きコイルの厚みが厚くなってしまう問題を生じる。本発明では、この巻始め端子５を防磁シート３のスリット４に入れることで、防磁シート付きコイル１を薄くすることができ、無接点方式電力伝送による充電を行うための携帯電話の受電コイルとして好適な極薄化を達成する。 This coil 2 is an ultrathin 1-row to 3-row multi-layer coil suitable as a power receiving coil for a mobile phone for charging by contactless power transmission.

In this example, the coil 2 has a donut shape, and the winding start terminal 5 protrudes from the coil body in the thickness direction of the coil as shown in FIG. Therefore, when this coil 2 is joined on a flat magnetic shielding sheet, there arises a problem that the thickness of the coil with the magnetic shielding sheet is increased by the thickness of the winding start terminal 5. In the present invention, by inserting the winding start terminal 5 into the slit 4 of the magnetic shielding sheet 3, the coil 1 with the magnetic shielding sheet can be made thin, and as a power receiving coil of a mobile phone for charging by contactless power transmission.

For example, it is good also as shapes, such as L shape and S shape. As a method of forming the slit 4 in the thin magnetic-shielding sheet 3, it can be easily performed using a known processing method such as punching.

本実施形態では、防磁シート３とコイル２とを接合する手段として、図１に示すように、両面テープ６（両面粘着シート）を用いている。この場合、コイル２の巻始め端子５が当接する部分は、両面テープ６が撓んで巻始め端子５を包みながらスリット４に収容されるので、特に加工を施す必要はないが、両面テープ６の巻始め端子５が当接する部分に切れ目やスリットを設けておいても良い。   In this embodiment, double-sided tape 6 (double-sided pressure-sensitive adhesive sheet) is used as means for joining the magnetic-shielding sheet 3 and the coil 2 as shown in FIG. In this case, the portion of the coil 2 where the winding start terminal 5 abuts is accommodated in the slit 4 while the double-sided tape 6 is bent and wraps around the winding start terminal 5. A cut or a slit may be provided in a portion where the winding start terminal 5 abuts.

You may do it.

また、本実施形態では、図１に示すように、防磁シート３とコイル２とを両面テープ６を介して接合し、さらにコイル２の周囲に透明な合成樹脂製フィルムからなる外枠７を貼り付けているが、両面テープ６をコイル２の外寸法と合わせて用いる場合や前記接着剤を用いる場合には、外枠７を省いても良い。   In this embodiment, as shown in FIG. 1, the magnetic shielding sheet 3 and the coil 2 are joined via a double-sided tape 6, and an outer frame 7 made of a transparent synthetic resin film is attached around the coil 2. However, the outer frame 7 may be omitted when the double-sided tape 6 is used together with the outer dimension of the coil 2 or when the adhesive is used.

本実施形態の防磁シート付きコイル１は、コイル２の厚み方向に突出した巻始め端子５が収容されるスリット４を有する防磁シート３を用い、コイル２の巻始め端子５を防磁シート３のスリット４に合致させた状態で防磁シート３にコイル２を接合した構成としたので、無接点方式電力伝送による充電を行うための携帯電話の受電コイルとして好適な極薄化を達成可能な防磁シート付きコイル１を提供することができる。   The coil 1 with a magnetic shielding sheet of the present embodiment uses a magnetic shielding sheet 3 having a slit 4 in which a winding start terminal 5 protruding in the thickness direction of the coil 2 is accommodated, and the winding start terminal 5 of the coil 2 is a slit of the magnetic shielding sheet 3.
