1 to 8 are perspective views showing various embodiments of a magnetic member having an asymmetric structure according to the present invention. The magnetic member 100 includes a polarity display unit 110 having a predetermined shape that indicates a specific polarity of the N and S poles. The magnetic member 100 is a part that can attach and detach the body of the portable electronic device (e.g., tablet PC, mobile phone, etc.) and the keyboard or the case body of the protective case of the portable electronic device and the keyboard by magnetic force, It has an asymmetrical structure by the display part and has an assembling directionality. Therefore, since the magnetic member 100 of the present invention is provided with the direction of assembly by the polarity display portion, it can be inserted and aligned in one polarity direction when inserted (assembled) into various frames, It is possible to reduce the defective rate of the product itself.

According to one example, the magnetic member 100 may be a permanent magnet. In this case, as shown in FIGS. 1 to 4, a polarity display unit 110 having a predetermined shape for displaying the polarity of the N-pole and the S-pole is formed at one end of the permanent magnet 100 have.

Wherein the permanent magnet comprises a single pole; Or a multipolar magnet in which at least two poles and at least two poles are formed through multipolar magnetization.

A polarity indicating portion 110 having a predetermined shape is formed at one end of the permanent magnet. The shape of the polarity display part 110 is not particularly limited because it is formed only on the polarity side of either of the N-polarity and S-polarity and only shows a specific polarity. For example, the shape of the polarity display portion 110 may be a notch shape (specifically, V-shaped notch, U-shaped notch, etc.) shown in FIG. 1, a projection shape shown in FIGS. 2 and 3, A shape of a depressed pattern shown in FIG. 6A, a groove shape, and the like, but is not limited thereto.

According to another example, the magnetic member 100 may be a shielding magnet. The shielding magnet includes a permanent magnet (120); And a polar display portion 110 having a predetermined shape for displaying the polarity of one of an N-pole and an S-pole at one end thereof, and a permanent magnet inserting portion 131 for inserting the yoke (yoke) 130). ≪ / RTI > At this time, the permanent magnet 120 and the yoke 130 may be integrated or separated.

Specifically, in the shielding magnet, the permanent magnet 120 may be a single pole; Or a multipolar magnet in which at least two poles and at least two poles are formed through multipolar magnetization.

The yoke 130 shields the magnetic force of at least one of the magnetic forces of the permanent magnets to strengthen the magnetic force in the unshielded direction. The material, shape, and size of the yoke 130 can be designed according to the type, shape, size, magnetic force, shielding direction, and the like of the magnetic body. For example, the material of the yoke may be a magnetic material having a high magnetic permeability, and may be steel or the like. The shape of the yoke may be a plate shape, a tube shape, a columnar shape in which an upper portion is opened and a lower portion is closed (for example, a U-shaped vertical section), or the like. At this time, the yoke may have a shape in which at least one of a plate shape, a tube shape, and a column shape is combined.

However, the polarity indication part 110 having a predetermined shape is formed at one end of the yoke 130 used in the present invention. As a result, the yoke 130 itself is provided with an assembling direction so that the direction of assembly is given to the magnetic member 100, so that misassembly of the magnetic member can be prevented when the magnetic member 100 is assembled to the frame body.

Since the polarity display unit 110 formed on the yoke 130 is formed only on one polarity side of the N and S poles as in the polarity display unit of the permanent magnets shown in Figs. 1 to 4, The shape thereof is not particularly limited. For example, the shape of the polarity display portion 110 may be a notch shape (specifically, V-shaped notch, U-shaped notch, etc.) shown in Fig. 5, a projection shape shown in Figs. 6 and 7, A shape of a depressed pattern shown in FIG. 6A, a groove shape, and the like, but is not limited thereto.

The magnetic member 100 of the above-described asymmetric structure can be manufactured by various methods known in the art. However, in the present invention, a magnetic member having an assembling direction can be manufactured by forming the polarity display portion that displays the polarity of either the N pole or the S pole at one end of the magnetic member by processing the outer shape of the magnetic member. As a result, when the magnetic member is inserted (assembled) into various frames, the magnetic member can be aligned and inserted in one polarity direction, thereby reducing the defective rate due to misassembly of the magnetic member, thereby lowering the defective rate of the product itself .

According to one example, when the magnetic member is a permanent magnet, the manufacturing method of the permanent magnet having the asymmetric structure is characterized in that the outer shape of one end of the permanent magnet is machined so that one polarity of the N pole and the S pole And forming a polarity display portion having a predetermined shape to display the polarity display portion. However, the present invention is not limited to the above-described manufacturing method, and the steps of each process may be modified or selectively mixed as necessary.

Examples of the method of forming the outer shape of the permanent magnet usable in the present invention include, but are not limited to, cutting, polishing, and the like.

According to another example, in the case where the magnetic member is a shielding magnet, the method of manufacturing a shielding magnet having an asymmetric structure may include the step of machining the outer shape of the one end of the yoke so that one pole of the N pole and the S pole Forming a polarity display portion of a predetermined shape to be displayed; Forming a permanent magnet inserting portion for inserting a permanent magnet on the yoke; And forming a magnetic member by inserting a permanent magnet into the permanent magnet inserting portion. However, the present invention is not limited to the above-described manufacturing method, and the steps of each process may be modified or selectively mixed as necessary.

In the present invention, the outer shape processing of the yoke includes cutting, bending, pressing, drawing, and the like, but is not limited thereto.

The method of forming the permanent magnet inserting portion is not particularly limited as long as it is a method commonly known in the art. For example, there are cutting, bending, pressing, drawing, and the like. At this time, the shape of the permanent magnet inserting portion is designed according to the shape of the inserted permanent magnet.
