Description

Connection structure Technical Field Cross Reference to Related Applications This application claims priority and benefit from korean patent application No. 10-2021-0001128 filed in the korean intellectual property office on day 1 and 5 of 2021, the entire contents of which are incorporated herein by reference. Technical Field Embodiments disclosed in the present disclosure relate to a connection structure of a connector. Background Typically, a component called a connector is used to connect a plurality of wires or a plurality of devices through which current flows. In the connector, factors associated with connection and disconnection between two connection terminals are considered to be important. In particular, one of the important factors is to reduce the cost by simplifying the connection structure. Examples of the connector typically include a line connector, an FFC (flexible flat cable) connector, and the like. In general, a connector includes therein an injection molded product configured to constitute a housing, and a mounting structure on which connector terminals and a PCB (printed circuit board) are mounted. Since the connector has several complicated parts as described above to reliably couple two connection terminals, it is necessary to minimize these parts.

According to an embodiment, the first connection portion may comprise a ferromagnetic element, and the second connection portion may comprise a steel plate. According to an embodiment, the first member may include a first guide portion and the second member may include a second guide portion, and the first guide portion and the second guide portion may be aligned with each other when the first member and the second member are coupled to each other. According to an embodiment, the first guide portion may include a guide block, and the second guide portion may include a guide groove, and the first member and the second member may be aligned with each other when the first guide portion and the second guide portion are coupled with each other. According to an embodiment, the first connection portion and the second connection portion may have a plurality of blocks configured to correspond to each other in a one-to-one manner. According to an embodiment, when at least one of the first connection portion and the second connection portion includes a magnet, the plurality of blocks may be disposed such that polarities of adjacent blocks are opposite to each other. According to an embodiment, the first member may comprise a film configured to protect the conductor pattern. According to an embodiment, a portion of the membrane where the first member is brought into contact with the second member may be partially removed. According to an embodiment, when the magnetic force between the first connection portion and the second connection portion is equal to or higher than a reference value, at least one of the first connection portion and the second connection portion may be attachable or detachable by a jig having a polarity opposite to that of the at least one of the first connection portion and the second connection portion. According to an embodiment, the second member may have a structure in which the conductive pad and the IC circuit are disposed on a Printed Circuit Board (PCB). Advantageous effects The connection structure according to the embodiments disclosed in the present disclosure is constructed by using a member having magnetism such as a ferromagnetic element to reduce the cost required for manufacturing the connector and to make it easy to connect or disconnect two connection terminals of the connector.
