[0032] Figure 1 This is a view illustrating components configured to implement a connection structure according to an embodiment disclosed in this disclosure.

[0033] Figure 1 The connector shown includes a connection structure according to an embodiment disclosed in this disclosure. Figure 1 The connector shown can have a structure in which the first component 100 and the second component 200 are connected to each other. That is, Figure 1 The connector shown can have the following structure: a first component 100 and a second component 200 are connected to each other such that the first component 100 is located at the upper end and the second component 200 is located at the lower end. For example, Figure 1 The connection structure shown can be applied to FFC type connectors.

[0034] In this configuration, the first component 100 may include a first connecting portion 110, a first guiding portion (guide block) 120, a connecting portion 130, a conductor pattern 140, and an insulating film 150. Additionally, the second component 200 may include a second connecting portion 210, a second guiding portion (guide groove) 220, a PCB 230, a conductive pad 240, and an IC circuit 250.

[0035] The first connecting portion 110 of the first component 100 can interact with the second connecting portion 210 of the second component 200 to connect the first component 100 and the second component 200. In this case, as in Figure 1 As illustrated in the diagram, the first connecting portion 110 may be disposed on one surface (e.g., the upper end) of the first member 100, and the second connecting portion 210 may be disposed on another surface (e.g., the lower end) of the second member 200. However, the positions of the first connecting portion 110 and the second connecting portion 210 are not limited to those shown in the diagram. Figure 1 The positions shown are as indicated. The first connecting portion 110 can be located at any point on the first member 100, and the second connecting portion 210 can be located at any point on the second member 200.

[0036] At least one of the first connecting portion 110 and the second connecting portion 210 may include a magnetic object. For example, the first connecting portion 110 may include a ferromagnetic element (e.g., neodymium), and the second connecting portion 210 may include a steel plate. Thus, the conductor pattern 140 of the first component 100 and the conductive pad 240 of the second component 200 can be electrically connected to each other by magnetic force between the first connecting portion 110 and the second connecting portion 210.

[0037] When the first component 100 and the second component 200 are connected, the first guide portion 120 of the first component 100 and the second guide portion 220 of the second component 200 can be aligned with each other. In this case, as in Figure 1 As illustrated in the figure, the first guide portion 120 may be a guide block protruding from another surface of the first member 100, and the second guide portion 220 may be a guide groove formed in one surface of the second member 200, such that the first guide portion 120 may be inserted into the guide groove.

[0038] As described above, since the first guide portion 120 provided on the first member 100 is connected to the second guide portion 220 provided on the second member 200, the first member 100 and the second member 200 can be aligned with each other. However, the shapes of the first guide portion 120 and the second guide portion 220 are not limited to those described above. Figure 1 The shape shown. Besides... Figure 1 The shapes shown are not limited to the first guide portion 120 and the second guide portion 220, which can also have various shapes.

[0039] The coupling 130 can attach the first connecting portion 110 to the first member 100. In this case, as described above, the coupling 130 can attach the first connecting portion 110 to the first member 100 such that the first member 100 and the first connecting portion 110 can be attached to and detached from each other, allowing the first connecting portion 110 to be removed by a clamp. For example, the coupling 130 is configured as a magnet. One surface of the coupling 130 can be attached to the first member 100 by an adhesive (not shown), and the other surface of the coupling 130 can be attached to the first connecting portion 110 by magnetic force.

[0040] The conductor pattern 140 can be made of a conductive material and performs the function of transmitting electrical signals from a device connected to the first member 100. For example, in Figure 1 As illustrated in the figure, the conductor pattern 140 may have a shape comprising a plurality of wires arranged side by side in the first member 100.

[0041] The insulating film 150 can be used to insulate the conductor pattern 140 included in the first member 100 and to provide external protection for the conductor pattern 140. In this case, the conductor pattern 140 may have a structure in which it is laminated between two insulating films 150 by an adhesive (not shown). In this case, the portion of the insulating film 150 in contact with the conductor pattern 140 and the second member 200 can be removed, such that the conductor pattern 140 is electrically connected to the conductive pad 240 of the second member 200.

[0042] The PCB 230 disposed on the second component 200 may include a conductive pad 240 and an IC circuit 250. The conductive pad 240 is made of a conductive material, such that the conductive pad 240 can receive electrical signals from the conductor pattern 140 of the first component 100 and transmit electrical signals from a device connected to the second component 200 to the conductor pattern 140. In addition, the electrical signals received through the conductive pad 240 can be transmitted to a device connected to the second component 200 through the IC circuit 250.

[0043] As described above, the connection structure according to the embodiments disclosed in this disclosure is constructed by using a magnetic component, such as a ferromagnetic element, to reduce the cost required to manufacture the connector and to make it easy to connect or disconnect the two connection terminals of the connector.

[0044] Figure 2 This is a view illustrating the structure of a component including a connecting portion for implementing a connection structure according to an embodiment disclosed in this disclosure.

[0045] Figure 2 (a) is along Figure 1 The cross-sectional view taken by line A-A' in the diagram. In this case, as in... Figure 1 As illustrated in the diagram, the conductor pattern 140 of the first component 100 may have a shape comprising multiple wires. Additionally, the conductor pattern 140 may be attached to the insulating film 150 via an adhesive 160. (As shown in...) Figure 2 As illustrated in (a), conductor pattern 140 may have a structure that is stacked between two insulating films 150.

[0046] Figure 2 (b) A portion 170 is illustrated, in which a portion of the insulating film 150 of the first member 100 is removed. The portion of the insulating film 150 in which the conductor pattern 140 of the first member 100 contacts the conductive pad 240 of the second member 200 is removed, such that the conductor pattern 140 of the first member 100 contacts the conductive pad 240 of the second member 200.

[0047] That is, reference Figure 1The portion of the insulating film 150 disposed on the other surface of the first component 100 corresponding to the area on one surface of the second component 200 where the conductive pad 240 is disposed is removed, so that the conductor pattern 140 of the first component 100 and the conductive pad 240 of the second component 200 can make physical / electrical contact with each other.

[0048] Figure 3 This is a view illustrating components configured to implement a connection structure according to another embodiment disclosed in this disclosure. Similar to... Figure 1 The connector shown Figure 3 The connector shown can also have a structure in which the first component 100 and the second component 200 are connected to each other. That is, the connector can have a structure in which the first component 100 and the second component 200 are connected to each other such that the first component 100 is located at the upper end and the second component 200 is located at the lower end.

[0049] Even in this case, the first component 100 may include a first connecting portion 110, a bonding portion 130, a conductor pattern 140, and an insulating film 150. Additionally, the second component 200 may include a second connecting portion 210, a PCB 230, a conductive pad 240, and an IC circuit 250. In this case, because the first connecting portion 110, bonding portion 130, conductor pattern 140, and insulating film 150 of the first component 100, and the second connecting portion 210, PCB 230, conductive pad 240, and IC circuit 250 of the second component 200 are connected to... Figure 1 Those shown are largely the same, so in Figure 3 The lieutenant general will omit its detailed description. Additionally, Figure 3 For convenience, the first guide portion 120 and the second guide portion 220 are not shown, but they may be included if necessary.

[0050] The difference is that, for example Figure 3 As shown, the first connecting portion 110 of the first component 100 and the second connecting portion 210 of the second component 200 are arranged in the form of multiple blocks, rather than as shown in the diagram. Figure 1 As shown, they are integrated. In this case, the blocks of the first connecting part 110 and the second connecting part 210 can be placed in a one-to-one correspondence with each other.

[0051] Additionally, when at least one of the first connecting portion 110 and the second connecting portion 210 includes a magnet, the plurality of blocks can be arranged such that the polarities of two adjacent blocks are opposite to each other. For example, as in Figure 3As illustrated in the diagram, when the first connecting portion 110 is a ferromagnetic element, the blocks can be repeatedly placed such that the polarities of adjacent blocks are opposite to each other. As described below, this is to facilitate the release of the magnet of the first connecting portion 110 using a clamp by forming a closed loop that blocks external magnetic forces through the magnetic field formed by the first connecting portion 110.

[0052] Figure 4 This is a view illustrating a clamp configured to attach or detach a connection portion of a connection structure according to another embodiment disclosed in this disclosure.

[0053] refer to Figure 4 The clamp 300 according to the embodiments disclosed in this disclosure may include a magnet portion 310, a handle 320, and a connecting portion 330. Specifically, when the magnetic force between the first connecting portion 110 and the second connecting portion 210 is equal to or higher than a reference value (e.g., when it is difficult to directly release the magnet using manual force), Figure 4 The clamp 300 shown can be used to attach or detach at least one of the first connection portion 110 and the second connection portion 210 by using a magnet portion 310 having a polarity opposite to that of at least one of the first connection portion 110 and the second connection portion 210.

[0054] Additionally, will refer to Figure 4 The first connecting portion 110 provided on the first member 100 is described as having a ferromagnetic element configuration. However, the connecting structures disclosed in this disclosure are not limited to this. The second connecting portion 210 may be a ferromagnetic element, or both the first connecting portion 110 and the second connecting portion 210 may be ferromagnetic elements.

[0055] The magnet portion 310 can be configured to correspond one-to-one with a plurality of magnet blocks of the first connecting portion 110, and is positioned such that each magnet portion 310 has a polarity opposite to that of each block of the first connecting portion 110. Therefore, the magnet portion 310 can be magnetically connected to the first connecting portion 110. When the magnet portions 310 and the first connecting portion 110 with opposite polarities are magnetically connected to each other, a closed loop of the magnetic field is formed, and external magnetic force is blocked, thereby eliminating the magnetic force between the first member 100 and the first connecting portion 110. Figure 4 (Magnetic disconnection area in the middle). Therefore, the first connecting part 110 can be easily removed from the first component 100 by means of the clamp 300.

[0056] The magnet portion 310 can be attached to the handle 320, and the handle 320 can be configured to be held by a user. Therefore, the user can grasp the handle 320 and bring the magnet portion 310 of the clamp 300 into contact with the first connecting portion 110 of the first member 100 of the connector. Thus, even if the user cannot directly release the first connecting portion 110 due to the strong magnetic force between the first connecting portion 110 and the second connecting portion 210, the user can easily remove the first connecting portion 110 from the first member 100.

[0057] The connecting portion 330 can attach the magnet portion 310 to the lower end of the handle 320 of the clamp 300. In this case, the connecting portion 330 can have sufficient connecting force to allow the first connecting portion 110 to be detached from the first member 100.

[0058] As described above, the connection structure according to the embodiments disclosed in this disclosure is constructed by using a magnetic component, such as a ferromagnetic element, to reduce the cost required to manufacture the connector and to make it easy to connect or disconnect the two connection terminals of the connector.

[0059] All the constituent elements constituting the embodiments disclosed in this disclosure may be combined and integrally connected or operated, but the embodiments disclosed in this disclosure are not necessarily limited to these embodiments. That is, one or more of the constituent elements may be selectively combined and operated within the purpose of the embodiments disclosed in this disclosure.

[0060] Furthermore, unless explicitly stated otherwise, the words “comprise,” “include,” or “have,” as well as variations such as “comprises,” “comprising,” “includes,” or “has,” should be understood to mean including the described elements but not excluding any other elements. Unless otherwise defined, all terms including technical or scientific terms may have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments disclosed in this disclosure pertain. Terms such as those defined in common dictionaries may be interpreted as having meanings consistent with their meanings in the relevant technical context and should not be interpreted as having ideal or overly formal meanings unless explicitly defined in this disclosure.
