[0002] This application claims priority to Korean Patent Application No. 10-2020-0091281, filed with the Korean Intellectual Property Office on July 22, 2020, the disclosure of which is incorporated herein by reference.

[0003] The present invention relates to a connector structure, and more particularly, to a connector structure including a magnet. Background Technology

[0004] Recently, due to the rapid increase in demand for portable electronic products such as laptops, cameras and mobile phones, and the formalization of the development of electric vehicles, energy storage batteries, robots, satellites, etc., research on high-performance rechargeable and rechargeable batteries is being actively carried out.

[0005] Currently commercially available rechargeable batteries include nickel-cadmium (NiCd), nickel-metal hydride (NiMH), nickel-zinc (NiZn), and lithium-ion batteries. Among these, lithium-ion batteries are gaining attention compared to nickel-based batteries due to their advantages such as free charging and discharging, very low self-discharge rate, and high energy density due to virtually no memory effect. Because various flammable materials are embedded in the rechargeable battery, there is a risk of heat generation and explosion due to overcharging, overcurrent, and other external physical impacts. Accordingly, battery packs can be connected using connectors to detach them from external devices as needed. However, a problem exists that a relatively strong force is required to connect or disconnect the battery pack from external devices, and therefore, the connectors are susceptible to damage from this strong force. Summary of the Invention

[0006] Technical issues

[0007] The present invention was invented to solve the above-mentioned technical problems, and the object of the present invention is to provide a connector structure in which a male connector and a female connector can be easily connected to each other by using a magnet.

[0008] Technical solution

[0009] The connector structure according to an embodiment of the present invention may include a connecting portion, an outer casing, and a first removal tool. In a connected mode, the connecting portion may be connected to a female connector, and in a disconnected mode, the connecting portion may be disconnected from the female connector. The outer casing may include a first magnet on a first surface surrounding the connecting portion, and the outer casing is configured to attract the female connector using the magnetic force of the first magnet. The first removal tool may be configured to rotate a second magnet in the disconnected mode, thereby weakening the magnetic force.

[0010] A connector structure according to another embodiment of the present invention may include a coupling portion, a housing, and a removal tool. In a coupling mode, the coupling portion may be coupled to a female connector, and in a separation mode, the coupling portion may be detached from the female connector. The housing may include a first magnet on a first surface surrounding the coupling portion, and the housing is configured to attract the female connector using the magnetic force of the first magnet. In the separation mode, the removal tool may be moved closer to the housing and is configured to weaken the magnetic force using a second magnet. In the separation mode, a portion of the second magnet facing a portion of the first magnet may have a polarity different from that of the portion of the first magnet.

[0011] Beneficial effects

[0012] According to embodiments of the present invention, a connector structure (e.g., a male connector) coupled to a female connector may include a magnet. In a coupled mode, the connector structure can be more easily coupled to the female connector by using the magnetic force of the internal magnet. In a disengaged mode, the connector structure can use the magnet of a removal tool to counteract the magnetic force. Therefore, the female connector can be disengaged from the connector structure without being affected by the magnetic force acting in the coupled mode. Attached Figure Description

Figure 2 This is a conceptual view used to explain a method for separating a connector from a connector structure according to an embodiment of the present invention. To aid in understanding the invention, it will be described together. Figure 1 and Figure 2 .

[0028] Connector structure 100 may include a housing 110, removal tools 120 and 130, and a connecting portion 140. Connector 200 may include a housing 210 and a connecting portion 220. For example, connector structure 100 may be a male connector, and connector 200 may be a female connector. Connector structure 100 may be connected to or disconnected from connector 200 depending on its operating mode.

[0029] Connector structure 100 can be connected to a battery pack. In this case, connector 200 can be connected to the internal circuitry of various devices such as vehicles, portable cameras, and mobile phones. However, the invention is not limited thereto, and connector structure 100 can be connected to the internal circuitry of various devices, and connector 200 can be connected to a battery pack. When connector structure 100 and connector 200 are connected to each other, connector structure 100 or the device connected to connector 200 can receive power from connector 200 or the battery pack connected to connector structure 100. In the following description, "connection mode" means the operating mode of connector structure 100 when connector 200 is connected to connector structure 100. "Disconnection mode" means the operating mode of connector structure 100 when connector 200 is disconnected from connector structure 100.

[0030] The connecting part 140 may include multiple terminals. Figure 1 The diagram shows a structure in which four terminals are disposed in the connecting part 140, but the present invention is not limited thereto.

[0031] The connecting portion 220 may include multiple terminals. The number of terminals included in the connecting portion 220 may be the same as the number of terminals included in the connecting portion 140. Figure 1 The diagram shows a structure in which four terminals are disposed in the connecting part 220, but the present invention is not limited thereto.

[0032] When connector structure 100 is connected to connector 200, the plurality of terminals of connector 140 can be inserted into the plurality of terminals of connector 220. When connector structure 100 is connected to connector 200, current can flow through the plurality of terminals of connector 140 and connector 220.

[0033] The outer cover 110 may be a structure that surrounds the connecting portion 140. The connecting portion 140 may be included within the outer cover 110. The outer cover 210 may be a structure that surrounds the connecting portion 220. The connecting portion 220 may be included within the outer cover 210. When the connector structure 100 is connected to the connector 200, the outer cover 210 may be inserted into the outer cover 110. Each of the outer covers 110 and 210 may be made of an insulating material.

[0034] In this specification, it is assumed that the outer cover 110 includes four surfaces. Of these four surfaces, the surface facing the removal tool 120 is referred to as the first surface. Of the remaining three surfaces, the surface facing the removal tool 130 is referred to as the second surface. Of the remaining two surfaces, the surface in contact with the bottom is referred to as the third surface. The remaining surfaces are referred to as the fourth side.

[0035] The outer casing 110 may include circular magnets 111 and 112. Figure 1 In this embodiment, it is assumed that the outer cover 110 includes a first circular magnet 111 and a second circular magnet 112 on the first and second surfaces, respectively, but the invention is not limited thereto. The outer cover 110 may include only one circular magnet, or it may include two or more circular magnets. Moreover, when the outer cover 110 includes one circular magnet, the circular magnet may be placed on any of the four surfaces of the outer cover 110.

[0036] Since the circular magnet 112 has a structure that is substantially the same as that of the circular magnet 111, the circular magnet 111 will be mainly described in the following description.

[0037] The circular magnet 111 may include a first pole and a second pole. When the first pole is the N pole, the second pole is the S pole, and when the first pole is the S pole, the second pole is the N pole.

[0038] The circular magnet 111 can have a cylindrical shape. The height of the cylinder can be less than or equal to the thickness of the first surface of the outer casing 110.

[0039] The circular magnet 111 can be divided into four quadrants. In the following description, dividing the circular magnet into specific shapes means that the circular magnet is divided into pillars, each pillar having a specific shape. A pillar having a specific shape means that the top surface of the pillar has a specific shape. That is, dividing the circular magnet 111 into four quadrants means that the circular magnet 111 is divided into four pillars. Each quadrant can be a first pole or a second pole. Two quadrants in the quadrant can be the first pole, and the other two quadrants can be the second pole. Adjacent quadrants can have different polarities. In the accompanying drawings of this specification, portions filled with different patterns indicate different polarities. For example, in the circular magnet 111, portions filled with diagonal lines can represent the first pole, and portions filled with dots can represent the second pole. However, the invention is not limited to this, and the circular magnet 111 can be divided into 2n circles or various shapes. Here, "n" can be a positive number. (See reference...) Figures 4a to 4c Various embodiments of the circular magnet 111 are described.

[0040] The boundary line dividing the circular magnet 111 may not be parallel to the plane on which the connector structure 100 is placed (or the direction in which the connector 200 is close to the connector structure 100). Because the boundary line is not placed parallel to the plane on which the connector structure 100 is placed, a larger magnetic force can be applied to the connector 200. However, the invention is not limited thereto, and the boundary line dividing the circular magnet 111 may be parallel to the plane on which the connector structure 100 is placed.

[0041] Because removal tool 130 has a substantially the same structure as removal tool 120, removal tool 120 will be described primarily in the following description.

[0042] The removal tool 120 may include a circular magnet 121 and a support wheel 122. The circular magnet 121 may have a structure substantially the same as that of the circular magnet 111. The circular magnet 121 may be positioned to face the circular magnet 111.

[0043] The removal tool 120 can use the support wheel 122 to rotate the circular magnet 121. In the coupled mode, the removal tool 120 can rotate the circular magnet 121 such that any part of the circular magnet 121 has the same polarity as a portion of the circular magnet 111 facing that portion. In the separated mode, the removal tool 120 can rotate the circular magnet 121 such that any part of the circular magnet 121 has a polarity different from that of a portion of the circular magnet 111 facing that portion. In the following description, having different polarities means that if one side is the first pole, the other side is the second pole. However, the invention is not limited thereto, and a rectangular magnet with a cuboid shape can be used instead of a circular magnet 121 with a cylindrical shape. When the circular magnet 121 is replaced by a rectangular magnet, the remaining circular magnets 111, 112, and 131 can also be replaced by rectangular magnets. As an example, the rectangular magnet can be... Figure 9a and Figure 9b The magnet 311b or magnet 311c. The boundary line dividing the rectangular magnet into the first and second poles can be perpendicular to the plane on which the connector structure 100 is placed. Furthermore, the rectangular magnet is fixed to the support wheel 122 and can rotate with the rotation of the support wheel 122. (Refer to...) Figure 5 Describe the structure.

[0044] The removal tool 130 can use the support wheel 132 to rotate the circular magnet 131. In the connection mode, the removal tool 130 can rotate the circular magnet 131 such that any part of the circular magnet 131 has the same polarity as the portion of the circular magnet 112 facing that part. In the separation mode, the removal tool 130 can rotate the circular magnet 131 such that any part of the circular magnet 131 has a polarity different from the polarity of the portion of the circular magnet 112 facing that part.

[0045] In this configuration, during the connection process, the magnetic force (specifically, the attractive force) generated by the circular magnets 111, 112, 121, and 131 acts on the connection portion 220. The connection portion 220 can be made of paramagnetic or ferromagnetic material. Therefore, the magnetic force can attract the connection portion 220 to the connector structure 100, specifically to the circular magnets 111, 112, 121, and 131. Due to this magnetic force, the device or user can connect the connector 200 to the connector structure 100 with only a relatively weak force.

[0046] In the separation mode, circular magnets 121 and 131 can respectively weaken and / or cancel the magnetic force generated by circular magnets 111 and 112. In the separation mode, the magnetic force caused by circular magnets 111 and 112 may not act on the connection portion 220. Therefore, the device or user can separate the connector 200 from the connector structure 100 without applying a force greater than that under normal circumstances. Therefore, damage to the connector structure 100 and the connector 200 caused by the connection and separation operations can be minimized.

[0047] Figure 1 This illustrates the operation of connector structure 100 in a connection mode. (Reference) Figure 1 In the connection mode, the polarity of a portion of circular magnet 111 is the same as the polarity of a portion of circular magnet 121 facing that portion. Although the polarity of circular magnet 112 is not... Figure 1 The instructions state that a portion of the circular magnet 112 has the same polarity as a portion of the circular magnet 131 facing that portion. Figure 2 This illustrates the operation of connector structure 100 in a separated mode. (Reference) Figure 2 In the separated mode, the polarity of a portion of circular magnet 111 differs from the polarity of a portion of circular magnet 121 facing that portion. Although the polarity of circular magnet 112 is not... Figure 2 The instructions state that the polarity of a portion of the circular magnet 112 is different from the polarity of a portion of the circular magnet 131 facing that portion.

[0048] In the foregoing, connector structure 100 has been described as rotating circular magnets 121 and 131 in both connection and separation modes; however, the invention is not limited thereto. Connector structure 100 may rotate circular magnets 111 and 112 instead of circular magnets 121 and 131 in both connection and separation modes to adjust the magnetic force acting on connector 200 as described above. Here, both circular magnets 121 and 131 and circular magnets 111 and 112 can be rotated. In this case, for the rotation of circular magnets 111 and 112, connector structure 100 may include support wheels surrounding each of the circular magnets 111 and 112.

[0049] Figure 3 It is used for explanation Figure 1 The flowchart shows the operation of the connector structure 100.

[0050] In operation S110, Figure 1 The connector structure 100 and connector 200 can operate in the connection mode.

[0051] In operation S120, the connector structure 100 can rotate the circular magnets 121, 131 of the removal tools 120, 130 and / or the circular magnets 111, 112 of the outer casing 110. (See reference...) Figure 1 Described, connector structure 100 can rotate circular magnets 121 and / or 111 such that any portion of circular magnet 121 has the same polarity as a portion of circular magnet 111 facing that portion. Connector structure 100 can rotate circular magnets 131 and / or 113 such that any portion of circular magnet 131 has the same polarity as a portion of circular magnet 112 facing that portion. Therefore, connector 200 can receive attractive forces on connector structure 100 by the magnetic forces generated by circular magnets 111, 112, 121, and 131.

[0052] In operation S130, connector 200 can be more easily connected to connector structure 100 by human intervention.

[0053] In operation S140, connector structure 100 and connector 200 can operate in a separate mode.

[0054] In operation S150, connector structure 100 can rotate the circular magnets 121, 131 of removal tools 120, 130 and / or the circular magnets 111, 112 of housing 110. (See reference...) Figure 1Described, connector structure 100 can rotate circular magnets 121 and / or 111 such that the polarity of any portion of circular magnet 121 is different from the polarity of a portion of circular magnet 111 facing that portion. Connector structure 100 can rotate circular magnets 131 and / or 113 such that the polarity of any portion of circular magnet 131 is different from the polarity of a portion of circular magnet 112 facing that portion. Therefore, in the connection mode, the magnetic force acting on connector 200 can be removed.

[0055] In operation S160, connector 200 can be removed from connector structure 100 without much force.

[0056] Figures 4a to 4c It is shown Figure 1 Conceptual views of various embodiments of the circular magnet 111.

[0057] Figure 1 The circular magnet 111 can be used Figures 4a to 4c One of the circular magnets 111a, 111b, and 111c can be used instead, and a circular magnet having the features of the invention disclosed in this specification can also be used instead. Accordingly, not only can the circular magnet 111 be replaced, but other circular magnets 112, 121, and 131 can also be replaced.

[0058] The circular magnet 111a can be divided into two semicircles. The boundary line between the semicircles can be a line perpendicular to the horizontal line or an oblique line. In the following description, a horizontal line means a line parallel to the horizontal line where the magnet is placed. Figure 1 The connector structure 100 has a planar line. One of the two semicircles can be the first pole, and the other semicircle can be the second pole.

[0059] The circular magnet 111b can be divided into 2m segments by 2m-1 lines. Here, "m" is a positive number. (Reference) Figure 4b "m" can be 4. The 2m-1 lines can be lines inclined at the same angle relative to the horizontal line. The 2m segments can be a first pole or a second pole. Specifically, adjacent segments among the 2m segments can have different polarities.

[0060] For reference Figure 1 Descriptively, a circular magnet 111c can be divided into 2n circles by n lines. Here, "n" is a positive number, and reference... Figure 4c "n" can be 3. The n lines can be lines passing through the origin. Each of the 2n-divided circles can be a first pole or a second pole. Specifically, 2n adjacent 2n-divided circles can have different polarities.

[0061] Figure 5 This is a conceptual view of a tool for removing rectangular magnets according to an embodiment of the present invention.

[0062] For reference Figure 5 Descriptively, Figure 5 The removal tool 120 may include a rectangular magnet 121' with a cuboid shape instead of a circular magnet 121 with a cylindrical shape. (As in...) Figure 5 As shown, the rectangular magnet 121' is fixed to the support wheel 122 and can rotate with the rotation of the support wheel 122. That is, the present invention can adjust the force acting on the object in the connection mode and the separation mode by rotating the rectangular magnet 121'. Figure 1 The magnetic force on connector 200.

[0063] Figure 6 This is a conceptual view for explaining a method of connecting a connector to a connector structure according to another embodiment of the present invention. Figure 7 This is a conceptual view used to explain a method for separating a connector from a connector structure according to another embodiment of the present invention. To aid in understanding the invention, it will be described together. Figure 6 and Figure 7 .

[0064] Figure 6 and Figure 7 The connector structures 300 shown, with configurations 310, 320, 330, and 340, can respectively provide with... Figure 1 and Figure 2 The connector structures 100 shown operate similarly to configurations 110, 120, 130, and 140. Therefore, refer to... Figure 6 and Figure 7 Repeated descriptions will be omitted, and the main focus will be on the differences between connector structure 300 and connector structure 100.

[0065] Connector structure 300 may include a housing 310, removal tools 320 and 330, and a coupling portion 340. Connector structure 300 may be coupled to or detached from connector 200 depending on the operating mode. For example, connector structure 300 may be a male connector, and connector 200 may be a female connector.

[0066] The connector structure 300 allows for the movement of removal tools 320 and 330 without rotating magnets 311, 312, 321, and 331 to adjust the magnetic force acting on the connector 200. In this configuration, magnets 321 and 331 can be positioned on removal tools 320 and 330 such that any portion of magnets 321 and 331 has a polarity different from the polarity of the portions of magnets 311 and 312 facing that portion. Furthermore, magnets 311, 312, 321, and 331 can be of various types. Each of magnets 311, 312, 321, and 331 can be a rectangular magnet with a cuboid shape, and reference... Figure 9b and Figure 9c Various embodiments of rectangular magnets are described.

[0067] However, the invention is not limited thereto, and the connector structure 300 can rotate magnets 311, 312, 321, and 331 and move removal tools 320 and 330 to adjust the magnetic force acting on the connector 200. In this case, it is not necessarily required that magnets 321 and 331 be placed on removal tools 320 and 330 such that any portion of magnets 321 and 331 has a different polarity than the portions of magnets 311 and 312 facing that portion.

[0068] In the connection mode, connector structure 300 allows removal tools 320 and 330 to move away from housing 310. Therefore, the magnetic force generated by magnets 311 and 312 on connector 200 can be stronger than the magnetic force generated by magnets 321 and 331. Connector 200 can receive an attractive force on connector structure 300 through the magnetic force generated by magnets 311 and 312. Due to this magnetic force, the device or user can connect connector 200 to connector structure 300 with only a weak force.

[0069] In the disengagement mode, connector structure 300 allows removal tools 320 and 330 to move closer to housing 310. The magnetic forces exerted on connector 200 by magnets 321 and 331 can be weakened and / or canceled by magnets 311 and 312. Therefore, the device or user can disengage connector 200 from connector structure 300 without applying a force greater than that under normal conditions. Thus, damage to connector structure 300 and connector 200 caused by engagement and disengagement operations can be minimized.

[0070] Figure 6 The operation of connector structure 300 in connection mode is shown. Figure 7 The operation of connector structure 300 in the split mode is shown. Comparison Figure 6 and Figure 7It was confirmed that in the separate mode, rather than the connected mode, the removal tools 320 and 330 were placed closer to the outer casing 310.

[0071] Figure 8 It is used for explanation Figure 6 The flowchart shows the operation of the connector structure 300.

[0072] In operation S210, Figure 6 The connector structure 300 and connector 200 can operate in the connection mode.

[0073] In operation S220, connector structure 300 allows removal tools 320 and 330 to move in a direction away from housing 310. Connector 200 can receive an attractive force on connector structure 300 by the magnetic force generated by magnets 112 and 121.

[0074] In operation S230, connector 200 can be more easily connected to connector structure 300 by human intervention.

[0075] In operation S240, connector structure 300 and connector 200 can operate in a separate mode.

[0076] In operation S250, connector structure 300 allows removal tools 320 and 330 to move closer to housing 310. The magnetic forces of magnets 112 and 121 can be counteracted by magnets 321 and 331 to remove the attractive force acting on connector 200.

[0077] In operation S260, connector 200 can be removed from connector structure 300 without much force.

[0078] Figures 9a to 9c It is shown Figure 6 Conceptual views of various embodiments of magnet 311.

[0079] Figure 6 Magnet 311 can be used Figures 9a to 9c The magnet 311 can be replaced by one of magnets 311a, 311b, and 311c, and can also be replaced by a magnet having the features of the invention disclosed in this specification. For example, magnet 311 can be replaced by... Figure 1 Magnet 111 and Figures 4a to 4c One of magnets 111a, 111b, and 111c may be substituted. Magnet 311 may also be substituted, as may other magnets 312, 321, and 331.

[0080] Magnet 311a can be a circular magnet. Magnet 311a can be divided into a single circle and a ring surrounding that circle. Correspondingly, magnet 321 can also be divided into a single circle and a ring surrounding that circle. In this case, when the circular portion and the ring portion of magnet 311a are the first pole and the second pole, respectively, the circular portion and the ring portion of magnet 321 can be the second pole and the first pole, respectively. Moreover, when the circular portion and the ring portion of magnet 311a are the second pole and the first pole, respectively, the circular portion and the ring portion of magnet 321 can be the first pole and the second pole, respectively.

[0081] Each of magnets 311b and 311c can be a rectangular magnet. A rectangular magnet can be divided into 2k rectangles by 2k-1 lines. Here, "k" is a positive number. (See reference) Figure 9b "k" can be 1, and refer to Figure 9c "k" can be 2. The 2k-1 lines can be lines perpendicular to the plane on which the connector structure 300 is placed. Each of the 2k rectangles can be a first pole or a second pole. Specifically, the rectangles among the 2k rectangles can have different polarities.

[0082] The foregoing description describes specific embodiments for implementing the present invention. The present invention will include not only the embodiments described above, but also embodiments with simple design variations or those that can be easily modified. Furthermore, the present invention will include techniques that can be easily modified and implemented using the embodiments. Therefore, the scope of the present invention is not limited by the detailed description of the inventive concept, but by the appended claims, and all differences within the scope will be interpreted as being included in the present invention.
