Abstract

A connection structure includes: a first connection part provided on a surface of a first member, the first member including at least one conductor pattern; and a second connection part provided on a surface of a second member, the second member having at least one conductive pad formed on a surface thereof and configured to be coupled to a surface of the first connection part by a magnetic force so that at least one conductor pattern and at least one conductive pad are electrically connected to each other.

First claim

The invention claimed is:

1 . A connection structure comprising:
a first connection part provided on a first surface of a first member, the first member including at least one conductor pattern on a second surface thereof; and a second connection part provided on a first surface of a second member, the second member having at least one conductive pad formed on a second surface thereof opposite the first surface of the second member and configured to be coupled to the second surface of the first connection part by a magnetic force so that the at least one conductor pattern and the at least one conductive pad are electrically connected to each other, wherein the first connection part and the second connection part are separated by the first member when the at least one conductor pattern is electrically connected to the at least one conductive pad,
wherein the first member comprises a first guide part on the second surface of the first member and the second member comprises a second guide part on the second surface of the second member, the first guide part positioned to align with the second guide part when the at least one conductor pattern is electrically connected to the at least one conductive pad,
wherein the first guide part is a single protrusion protruding from the second surface of the first member, and wherein the second guide part is a single recess defined in the second surface of the second member.

2 . The connection structure of claim 1 , wherein the first connection part comprises a ferromagnetic element, and the second connection part comprises a steel plate.

3 . The connection structure of claim 1 , wherein the single protrusion is a guide block, the single recess is a guide groove, and the first and second members are aligned with each other as the first and second guide parts are coupled to each other.

4 . The connection structure of claim 1 , wherein the first and second connection parts have a plurality of blocks configured to correspond to one another in a one-to-one manner.

5 . The connection structure of claim 4 , wherein when at least one of the first and second connection parts comprises a magnet, the plurality of blocks is disposed such that polarities of adjacent blocks are opposite to each other.

6 . The connection structure of claim 1 , wherein the first member comprises a film configured to protect the at least one conductor pattern.

7 . The connection structure of claim 6 , wherein a portion of the film is partially removed where the first member comes into contact with the second member.

8 . A system comprising the connection structure of claim 1 , wherein when the magnetic force between the first and second connection parts is equal to or higher than a reference value, at least one of the first and second connection parts is attachable or detachable by a jig detached from the first member and the second member, the jig having a polarity opposite to a polarity of at least one of the first and second connection parts.

9 . The connection structure of claim 1 , wherein the second member has a structure in which the at least one conductive pad and an IC circuit are provided on a printed circuit board (PCB).

10 . The connection structure of claim 1 , wherein the first surface of the first member faces away from the second member when the at least one conductive member is electrically connected to the at least one conductive pad.

11 . The connection structure of claim 1 , wherein the second surface of the first member is opposite the first surface of the first member.

12 . The connection structure of claim 11 , wherein, when the at least one conductor pattern is electrically connected to the at least one conductive pad, the second surface of the first member contacts the second surface of the second member, and the first surface of the first member opposes the first surface of the second member.

13 . The connection structure of claim 11 , wherein the first guide part is elongate, and wherein the second guide part is elongate.

14 . The connection structure of claim 13 , wherein, when the at least one conductor pattern is electrically connected to the at least one conductive pad, the first connection part is aligned with the second connection part, and the first and second guide parts are offset from the first and second connection parts.
