It should be understood that the invention is not limited in its application to the precise form disclosed, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

1 to 4 relate to a magnet connector according to a first embodiment of the present invention.

The magnetic connector 100 is a member that is coupled to the end portion of the receiving can and is connected to a magnetic connector or the like coupled to another receiving can using a magnetic force. The magnetic connector 100 may be connected to another magnetic connector or may be connected to another receptacle 500 through another connector member such as an intermediate connecting member 200 having an iron core or a magnet inside as shown in FIG. .

1 to 3 show the construction of the magnet connector according to the first embodiment.

The magnetic connector 100 according to the first embodiment includes a magnet 10, a main body portion 20, and a metallic body 30.

Here, the magnet 10 is shown as a spherical shape, but it may be a cylindrical shape, a disk shape, or the like.

The main body portion 20 is a portion that surrounds the magnet 10 so as not to be exposed to the outside, and an internal space 21a in which the magnet 10 is placed is formed therein. The body portion 20 is provided with a connection portion 24 to be coupled with the receptacle 500.

The internal space 21a of the main body 20 is formed to have a slightly larger size than the external shape of the magnet 10. Therefore, the magnet 10 is rotatable in the inner space 21a. The magnet 10 in the magnetic connector 100 is appropriately rotated and aligned in the magnetic force direction in accordance with the magnetic force forming direction, To the connector member or the intermediate connecting member.

The main body portion 20 is divided into a housing portion 21 for mounting the magnet 10 therein and a connecting portion 24 for coupling with a receiving cork or other connector member. The housing part 21 is divided into a first main body 22 and a second main body 23 in order to insert and seal the magnets 10 therein.

In the illustrated embodiment, the first body 22 is hemispherical in shape and a hemispherical groove is formed on the inner side of the first body 22 to form a part of the inner space 21a. The outer surface of the first main body 22 is formed as a curved surface at a portion contacting the other connector member or the intermediate connecting member.

The second body 23 is formed with hemispherical grooves which are the remaining portions of the inner space. Accordingly, when the first body 22 and the second body 23 are coupled, an internal space 21a having an airtight interior is formed. The second body 23 has a connecting portion 24 formed thereon. As shown in the figure, the second body and the connecting portion may be integrally manufactured or separately manufactured and assembled.

The metallic body 30 is brought into contact with the inside of the first main body 22. The metallic body 30 is made of a thin ferromagnetic metal, for example, an iron material is used. The metal body 30 is fixed to the inner wall surface of the first main body 22 in the form of a thin metal film formed on the inner wall of the first main body 22. Here, an adhesive may be used between the first body and the metallic body.

The concave inner curvature of the metal body 30 is equal to the curvature of the concave groove in the second body 23. Therefore, when the first main body 22 and the second main body 23, in which the metal body 30 is mounted, are assembled, a substantially perfect spherical space is formed. As the spherical magnet 10, which is slightly smaller than the inner diameter of the spherical space, enters the magnet 10, the magnet 10 can be freely rotated without interference in any direction.

The magnet 10 inside the magnet connector can be held in the state of being held by the metal body 30 even when the magnet connector 100 is not engaged with another magnet connector or the intermediate connecting member. As a result, it is prevented from bumping into the inner space, thereby preventing breakage due to noise or impact.

The first main body 22 and the second main body 23 are assembled by fitting the fitting groove 221 formed in the first main body 22, the fitting groove 31 of the metal body 30, The fitting protrusion 231 is involved.

First, a fitting protrusion 231 protrudes from the upper end of the second body 23. Although the pair of fitting projections 231 are radially arranged at the center of the cross section of the second main body 23 in the figure, the number of fitting projections can be variously changed.

At the lower end of the first main body 22, a fitting groove 221 is formed corresponding to the position of the fitting projection 231. The cross-sectional area of the fitting groove 221 is formed corresponding to the area of a part of the fitting projection 231 having a circular cross-section rather than the entire cross-sectional area.

On the other hand, at the lower end of the metal body 30 fixed to the inner wall surface of the first main body 22, a coupling groove 31 is formed corresponding to the fitting projection 231. At this time, the width of the width 311 of the engaging groove 31 is formed to be narrower than the width of the end face of the engaging protrusion 231 fitted in the engaging groove 31.

The fitting groove 221 of the first main body 22 and the fitting groove 31 of the metal body 30 are combined to form a groove into which the fitting protrusion 231 is engaged. The metal body 30 is made of a material stronger than the second body 23 made of synthetic resin. A part of the fitting protrusion 231 is inserted into the narrow engaging groove 31 so that the fitting protrusion 231 is firmly engaged while being deformed by the engaging groove 244 of a stronger material. As a result, the first body 22 and the second body 23 can be firmly assembled.

The method of forming the groove into which the fitting protrusion 231 is inserted by combining the fitting groove 31 of the metal body 30 and the fitting groove 221 of the first main body 22 is a method of making the thickness of the first body thin Lt; / RTI > In other words, in forming the groove into which the fitting protrusion having an appropriate thickness is inserted, the fitting protrusion, which is formed by forming the groove to be somewhat small, can be firmly fixed by using the rigidity of the material of the metal body.

This makes it possible to obtain a strong coupling force as compared with a method of forming a single groove in the first body, so that the thickness of the fitting protrusion and the thickness of the first body can be made thin. Since the thickness of the thin first main body 22 can utilize the magnetic force of the magnet 10 provided in the inner space to a great extent, the bonding force can be increased and the satisfaction of the user can be increased.

The connecting portion 24 connected to the lower portion of the first main body 22 is formed with a cylindrical mounting groove 241 through which the end of the receiving can is inserted. Further, a mounting protrusion 242 protruding from the bottom surface of the mounting groove 241 is formed at the end of the receiving can.

The length of the mounting projection 242 is formed to be shorter than the depth of the mounting groove 241 to prevent a safety accident that a user or the like sticks a finger or the like to the sharp end of the mounting projection 242.

When the receiving cans 500 are inserted into the mounting grooves 241, the mounting protrusions 242 pierce the center of the ends of the receiving cans 500. The end portions of the receiving cans 500 are pushed and compressed in the direction of the outer peripheral surface by the cross-sectional area occupied by the mounting projections 242, so that the receiving cans 500 inserted into the mounting grooves 241 are firmly coupled. Thereby, it is possible to prevent the pick-and-place from detaching from the magnetic connector when the user does not intend.

4 shows the connection of the intermediate connector and the magnet connector.

The intermediate connecting member 200 may have various shapes such as a hexahedron or a spherical shape. On the outer surface of the intermediate connecting member 200, a concave guide groove 210 is formed in accordance with the circular curved surface of the magnet connector. Also, although not shown in the figure, iron or spherical magnets are embedded in the intermediate connecting member 200.

The curvature of the guide groove 210 is substantially the same as the curvature of the hemispherical shape formed at the front end of the magnet connector 100. When the front end portion of the magnetic connector 100 is brought into contact with the guide groove 210, the spherical magnet inside the magnetic connector 100 rotates appropriately corresponding to the magnet inside the intermediate connecting member, and the magnets are pulled together with each other. In this state, the extending direction of the magnetic connector 100 can be adjusted. When the spherical magnet moves in a state of being in contact with the inner surface of the metal body, the magnetic connector 100 and the receptacle 500 are moved .

Figure 5 relates to a second embodiment of the present invention.

The magnetic connector 100 for a can type according to the second embodiment includes a magnet 10, a main body portion 20, and a connecting portion 24. The magnets and the main body portion may include the technical features of the first embodiment as they are, as long as they do not conflict with those described below.

In the second embodiment, the connecting portion 24 is a member connected to another connector member coupled to the receiving can.

The other connector member 300 shown has a hook 310 in a configuration for being connected to the middle of the pick-and-place. The hooks 310 are elastically opened and the intermediate portion of the can is interlocked and fixed therein. The illustrated hooks may have various other forms for securing the can. For example, in the form of a pin flanking the side of the can, or in the form of a connection of the above-described first embodiment to which the end is coupled.

The other connector member 300 is provided with a coupling portion 320 to which the coupling portion of the magnetic connector 100 according to the second embodiment is detachably coupled. Specifically, the engaging portion 320 includes an insertion groove 321 having a circular cross section with an open end. A pair of opposing locking projections 322 protrude from the inner circumferential surface of the insertion groove 321. Although not shown, a slit may be formed in the periphery of the locking protrusion 322 to facilitate elastic deformation of the locking protrusion.

The cylindrical body 243 is elongated so as to be insertable into the insertion groove 321. The cylindrical body 243 has an engagement protrusion 322 Which is recessed along the circumferential direction.

When the connecting portion 24 is pushed into the insertion groove 321, the locking protrusion 322 is elastically opened and separated in a direction away from each other, and the locking protrusion 322 enters the locking groove 244. Thus, the other connector member 300 and the magnetic connector 100 can be combined. Conversely, if you want to remove it, pull out the magnetic connector and detach the locking pin from the locking groove.

Fig. 6 relates to a magnetic connector for a can type model according to a third embodiment of the present invention.

The magnetic connector 100 according to the third embodiment includes the magnet 10, the main body 20, and the metal body 30, and within the range not conflicted with the following description, It may be the same as the magnet, the main body and the metal body of the embodiment.

The connecting portion 24 of the main body portion 20 is cylindrical in which the end portion thereof is opened, and the suction rubber 330 is mounted on the connecting portion 24.

Here, as is well known, the absorbent rubber 330 is made of a rubber material which is easily deformed by elasticity, and is adhered to a flat surface on a concave depressed surface to be firmly fixed.

The magnetic connector 100 according to the third embodiment can be used for firmly fixing a model manufactured by a pick-and-place machine to the floor of a mounting space such as a desk. Particularly, when the absorbent rubber 330 is used for fixing, there is no slip. It can also be used to fix a model to a wall or ceiling scene with a flat surface, such as a mirror or glass door.

Fig. 7 relates to a magnetic connector for a can type model according to a fourth embodiment of the present invention.

The magnetic connector 100 according to the fourth embodiment includes the magnet 10, the main body 20, and the metal body 30, and the above-described embodiment The technical characteristics of the examples can be provided as they are.

The outer surface of the housing portion 21 of the magnetic connector 100 according to the fourth embodiment has roughened concave and convex portions 211 formed on its surface. The shape of the concavities and the convexities is a quadrangular pyramid or a cylindrical pyramid having a pointed end, and the concavity and convexity is formed to be denser along the outer curved surface of the housing part.

The protrusions 211 increase the roughness of the outer surface of the housing portion 21, so that when the magnet connectors are attached to the housing portions 21 so as to come into contact with each other, sliding is prevented on the surfaces contacting each other, It is possible to maintain the connection angle between the two. Therefore, it is possible to precisely implement the connection part of the receptacle by using the magnetic connector 100. FIG.
