[0059] Thus, the substrate can be grounded to the shell.

[0060] Moreover, the substrate can be protected from external static electricity.

[0061] In addition, the durability of the aerosol generating device can be improved.

[0062] The screw 60 can penetrate the board 50 and be fixed to the bracket 30. The screw 60 can fix the board 50 so that the board 50 maintains contact with the second clip 44.

For example, the second clip 44 contacts the rear surface of the board 50, and the screw 60 can be inserted from the front to the rear to apply pressure so that the board 50 contacts the second clip 44.

[0063] FIG. 6 is a cross-sectional view taken along line B1-B2 in FIG.

[0064] 6, the ground terminal 40 can contact the shell 20. The first clip 46 of the ground terminal 40 can contact the shell 20. The first clip 46 can be broken off from the terminal frame 42 of the ground terminal 40.

[0065] The terminal frame 42 may be fixed to the bracket 30. The terminal frame 42 may be inserted into the bracket 30. The terminal frame 42 may be inserted into a coupling groove 32 formed in the bracket 30. The coupling groove 32 may fix the ground terminal 40 so as to maintain a distance t2 between the terminal frame 42 and the inner surface of the shell 20.

[0066] 7, the ground terminal 40 and the substrate 50 may be coupled to the bracket 30. The ground terminal 40 may be coupled to the bracket 30 prior to the substrate 50. For example, the ground terminal 40 may be inserted into the coupling groove 32 of the bracket 30, and then the substrate 50 may be coupled to the bracket 30.

[0067] The ground terminal 40 may be inserted into the coupling groove 32 of the bracket 30 in a direction perpendicular to the longitudinal direction of the body 10. The board 50 may be coupled to the bracket 30 in the longitudinal direction of the body 10. When the board 50 is coupled to the bracket 30, the board 50 may contact the second clip 44 of the ground terminal 40 coupled to the bracket 30. For example, the ground terminal 40 may be inserted rearward into the coupling groove of the bracket, and the board 50 may be inserted downward W1 and coupled to the bracket 30 to which the ground terminal 40 is coupled, so that the second clip 44 of the ground terminal 40 may contact the board 50.

[0068] The second clip 44 can be compressed toward the second terminal frame so as to correspond to the gap between the board 50 and the bracket 30 .

[0069] The second clip 44 of the ground terminal 40 may be bent to protrude in a direction in which the substrate 50 is positioned on the bracket 30. The second clip 44 may be bent to form an inclined surface 444 in a direction in which the substrate 50 approaches the second clip 44. When the substrate 50 is inserted into the bracket 30, the substrate 50 may contact the second inclined surface 444 of the second clip 44. The second clip 44 may have elasticity. For example, the substrate 50 may be coupled to the bracket 30 downward W1, and the substrate 50 may be inserted into the bracket 30 in a state in which the substrate 50 contacts the second inclined surface 444 of the second clip 44. The second clip 44 may be pressed in a direction opposite to the bending direction in a state in which the substrate 50 contacts the second clip 44. When the substrate 50 is removed, the ground terminal 40 may be restored to its original state.

[0070] The second clip 44 can be folded so as to expand in the opposite direction to the direction in which the substrate 50 approaches. For example, the substrate 50 approaches the ground terminal 40 from above, and the second clip 44 can be folded so as to expand downward.

[0071] The second clip 44 of the ground terminal 40 may be bent such that the inclined surface 444 is inclined in a direction opposite to the direction in which the substrate 50 is coupled to the bracket 30. For example, the substrate 50 may be coupled downward to the bracket 30, and the second clip 44 may be bent such that the inclined surface 444 is inclined upward.

[0072] Therefore, the ground terminal can stably maintain contact with the shell.

[0073] In addition, the assembly of the aerosol generating device can be improved.

[0074] After the ground terminal 40 and the board 50 are coupled to the bracket 30, the bracket 30 may be inserted into the shell 20. The bracket 30 may be inserted into the inside of the shell 20 through an open end of the shell 20. The bracket 30 may be inserted into the shell 20 in a direction W2 corresponding to a direction W1 in which the board 50 is coupled to the bracket. That is, the direction W1 in which the board 50 is inserted into the bracket 30 and the direction W2 in which the bracket 30 is inserted into the shell 20 may correspond to each other. For example, the board 50 may be coupled to the bracket in a downward direction W1, and the bracket 30 may be inserted into the shell 20 in a downward direction W2.

[0075] When the bracket 30 is inserted into the shell 20, the first clip 46 of the ground terminal 40 may come into contact with the shell 20. The first clip 46 may be bent so as to be raised to one side from the terminal frame 42. The first clip 46 may be bent so that the inclined surface 464 is inclined in the direction in which the shell 20 approaches. For example, the shell 20 approaches the ground terminal 40 from below, and the first clip 46 may be bent so that the inclined surface 464 is inclined downward.

[0076] The first clip 46 can be compressed toward the first terminal frame so as to correspond to the gap between the bracket 30 and the shell 20 .

[0077] Therefore, the ground terminal can stably maintain contact with the shell.

[0078] In addition, the assembly of the aerosol generating device can be improved.

[0079] 8 and 11, the terminal frame 42 may include a second terminal frame 422 to which the second clip 44 is connected. The second clip 44 may be folded from the second terminal frame 422. For example, the second clip 44 may be folded from the second terminal frame 422 toward the board 50.

[0080] The second clips 44 can extend from the terminal frame 42. The second clips 44 can extend from the second terminal frame 422. For example, the second clips 44 can extend from the terminal frame 42 toward the other side of the shell 20 opposite the open side of the shell 20 relative to the terminal frame 42.

[0081] The second clip 44 can protrude from the terminal frame 42 toward the substrate 50. For example, the second clip 44 can protrude from the terminal frame 42 toward the substrate 50 and bend to contact the substrate 50.

[0083] The terminal frame 42 may include a first terminal frame 424 to which a first clip 46 is connected. The first terminal frame 424 may be inserted into the coupling groove 32 of the bracket 30.

[0084] The first clip 46 may be connected to an inner peripheral end of the first terminal frame 424. The first clip 46 may be folded from the first terminal frame 424. For example, the first clip 46 may be folded from the first terminal frame 424 toward the shell 20.

[0085] A first bending portion 462 may be located at a connection portion between the first clip 46 and the first terminal frame 424. The first bending portion 462 may connect the first clip 46 and the first terminal frame 424.

[0086] The first terminal frame 424 may include a terminal groove 426 formed at an outer circumferential end thereof. The terminal groove 426 may be formed from the outer circumferential end of the first terminal frame 424 to the inside of the first terminal frame 424.

[0087] The second terminal frame 422 may be folded from the first terminal frame 424. The second terminal frame 422 and the first terminal frame 424 may be connected at a predetermined angle θ3. The predetermined angle θ3 may be an angle between the substrate 50 and an inner surface of the shell 20 adjacent to the substrate 50. The ground terminal 40 may contact one side of the substrate 50 and contact the inner surface of the adjacent shell 20. For example, the ground terminal 40 may contact the rear surface of the substrate 50 and the inner surface of the shell 20.

[0088] The second clip 44 may include a second inclined surface 444. The second clip 44 may have the second inclined surface 444 that forms an incline with respect to the terminal frame 42. The second clip 44 may be bent such that the second inclined surface 444 is formed from the second terminal frame 422. The second inclined surface 444 may form a predetermined angle with respect to the second terminal frame 422. For example, the second inclined surface 444 may extend from the terminal frame 42 and be inclined with respect to the terminal frame 42.

[0089] The second clip 44 may include a second contact portion 446 that contacts the substrate 50. The second contact portion 446 may extend from the second inclined surface 444.
