Therefore, it is possible to achieve an effect of simplifying the manufacturing process and reducing the production costs.

(30) FIG. 7 is an enlarged view of the main body part of the charging device according to the exemplary embodiment of the present invention. FIG. 8 is a view schematically illustrating a state in which a seating part is coupled to the housing in the main body part of the charging device according to the exemplary embodiment of the present invention.

(31) Referring to FIGS. 7 and 8, the main body part 110 of the charging device according to the exemplary embodiment of the present invention may further include a seating part 120 positioned on the extension portion 112b of the housing 112.

(32) More specifically, the seating part 120 is positioned on the extension portion 112b so as to surround the receiving portion 112a of the housing 112. The seating part 120 has a through portion, such that a part of the receiving portion 112a protrudes to the outside through the through portion.

(33) In addition, a magnet M is provided in the seating part 120. The magnet M enables the main body part 100 to be detachably coupled to the connection part 200 (see FIG. 9) to be described below.

(34) FIG. 9 is a view schematically illustrating the connection part of the charging device according to the exemplary embodiment of the present invention.

(35) Referring to FIG. 9, the connection part 200 of the charging device according to the exemplary embodiment of the present invention includes the second terminal part 210 and a third terminal part 220.

(36) The second terminal part 210 is provided at one end of the connection part 200 and connected to the first terminal part 110 (see FIG. 3) during the charging operation.

(37) The third terminal part 220 is provided at the other end of the connection part 200 and connected to an electronic device required to be charged.

(38) The connection part 200 may further include a fitting part 230.

(39) The fitting part 230 is spaced apart from the second terminal part 210 and provided in a circumferential direction of the second terminal part 210.

(40) A magnet M is provided in the fitting part 230. The magnet M enables the second terminal part 210 to be detachably coupled to the first terminal part 110 (see FIG. 3) of the main body part 100 as described above.

(41) In the present exemplary embodiment, the magnets M are provided in both the seating part 120 of the main body part 100 and the fitting part 230 of the connection part 200. However, in another exemplary embodiment, the magnet may be provided in any one of the main body part 100 and the connection part 200.

(42) Since the magnets are provided in the charging device according to the present invention as described above, the main body part and the connection part may be detachably coupled to each other, and as a result, it is possible to achieve an effect of improving convenience of use.

(43) An operation of the charging device according to the present invention will be described below.

(44) The main body part 100 and the connection part 200 of the charging device according to the present invention are coupled to each other by magnetic force during the operation of charging the electronic device.

(45) More specifically, the fitting part 230 of the connection part 200 is inserted into a space S (see FIG. 7) of the main body part 100 and coupled to the seating part 120 of the main body part 100 in a state in which the fitting part 230 is in contact with the seating part 120.

(46) In this case, the second terminal part 210 of the connection part 200 is connected to the first terminal part 110 of the main body part 100, and more specifically, the second terminal part 210 is fitted between the first gripping portions 114aa and the second gripping portions 114bb of the plurality of pairs of terminals 114, thereby implementing electrical connection.

(47) When the electronic device is not charged, for example, when a user needs to stop the charging operation to answer a phone call from the outside, the user may separate the main body part 100 from the connection part 200 with force stronger than the magnetic force. In this case, the strong force may be applied to the main body part 100 in various directions. Even though the strong force is applied in any direction, the elastic force made by the curved shape of the first gripping portion 114aa and the curved shape of the second gripping portion 114bb makes it easy to separate the main body part 100 and advantageously reduces the likelihood of damage to connected portions even in case of frequent separation.

(48) While the specific exemplary embodiments of the present invention have been described above, the present invention is not limited to the specific exemplary embodiments described above, various modifications can of course be made by any person skilled in the art to which the present invention pertains without departing from the subject matter of the present invention as claimed in the claims, and the modifications are within the scope defined by the claims. 100: Main body part 110: First terminal part 112: Housing 112a: Receiving portion 112aa: First region 112ab: Second region 112ac: Third region 112ad: Fourth region 112b: Extension portion 114: Terminal 114a: First terminal 114aa: First gripping portion 114b: Second terminal 114bb: Second gripping portion 120: Seating part 122: Opening portion 200: Connection part 210: Second terminal part 220: Third terminal part 230: Fitting part M: Magnet
