TECHNICAL FIELD

The present invention relates to a charging device, and more particularly, to a charging device in which a plurality of pairs of terminals in a main body part is manufactured in a state of being disposed in a housing and then installed in the charging device together with the housing, such that a manufacturing process may be simplified, production costs may be reduced, elastic force made by curved shapes of a first gripping portion and a second gripping portion of a terminal may reduce a likelihood of damage even in case of frequent separation, and the main body part and a connection part may be easily separated and coupled by means of a magnet.

BACKGROUND ART

A charging device in the related art is provided with a plurality of pogo pin-type terminals. There is inconvenience in assembling the charging device having the pogo pin-type terminals because the pogo pin-type terminals need to be separately manufactured and then arranged in the charging device, and this complicated process causes a problem of an increase in production costs.

In addition, even though only one of the plurality of pogo pin-type terminals installed in the charging device is defective, only the defective terminal cannot be replaced, and all the plurality of pogo pin-type terminals need to be replaced, which causes inconvenience.

In addition, because the pogo pin-type terminal has a straight shape, there is a problem in that a damage rate of the pogo pin-type terminal is high and durability of the pogo pin-type terminal deteriorates when the pogo pin-type terminal is frequently separated.

In addition, there are problems in that sparks may occur when dust is accumulated in a contact area between the pogo pin-type terminal and a connection terminal, the pogo pin-type terminal may be rusted when moisture is attached to the pogo pin-type terminal, and the charging device may be burnt out due to heat generated by the pogo pin-type terminal.

The receiving portion 112a is divided into a plurality of regions 112aa, 112ab, 112ac, and 112ad to receive the plurality of pairs of terminals 114. The first terminal 114a and the second terminal 114b, which are each pair of terminals, are received in each of the regions 112aa, 112ab, 112ac, and 112ad.

The extension portion 112b is stepped downward from the receiving portion 112a and extends outward from the receiving portion 112a.

According to the present invention, the plurality of pairs of terminals 114 is not assembled after being individually disposed in the charging device. However, the plurality of pairs of terminals 114 is manufactured in a state of being disposed in the housing 112 and then installed in the charging device together with the housing 112. Therefore, it is possible to achieve an effect of simplifying the manufacturing process and reducing the production costs.

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.

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.

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.

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.

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

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.

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.

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.

The connection part 200 may further include a fitting part 230.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
