Compared with the prior art, the antenna assembly of the present invention can be firmly assembled with the assembly, and at the same time, the antenna can be easily detached from the assembly as needed, without affecting the radiation performance of the antenna.

The first to fourth figures show an antenna assembly 1 provided in accordance with a preferred embodiment of the present invention.

The antenna assembly 1 includes an antenna 100 and an insulating assembly 200 assembled with the antenna 100.

The antenna 100 is integrally stamped from a metal sheet, and includes a first metal piece 110 in a first plane, an L-shaped second metal piece 120 extending upward from a side of the first metal piece 110, and a second metal piece. 120 extends upwardly from the third metal sheet 130 that is substantially perpendicular to the first plane in which the first metal sheet 110 is located. The second metal sheet 120 includes a first segment 121 that is perpendicular to the first plane and a second segment 122 that extends from the first segment 121 and that is parallel to the first plane. Therefore, the second metal piece 120 and the third metal piece 130 form a step shape. The first metal piece 110 serves as a grounding portion of the antenna 100, and a middle portion thereof is cut to form a metal piece, and the metal piece is bent upward to form an L-shaped protrusion 112. The tab 112 includes a support portion 1121 that is perpendicular to the first plane and a catch portion 1122 that is parallel to the first plane. The first metal piece 110 further includes a rectangular through hole 114 on one side of the tab 112. The second metal piece 120 serves as a connection portion of the antenna 100, and the third metal piece 130 serves as a radiation portion of the antenna 100.

The assembly 200 is made of a plastic material and has a shape that cooperates with the antenna 100 and the internal environment of the electronic device, and includes a slot 201 having an open end and a stop end, a bump 202 at the bottom, and a pair for the assembly. 200 is mounted in the mounting hole 203 in the electronic device and a strip-shaped filling block 204. To match the antenna, the assembly 200 also has a stepped surface 205 for attaching the second and third metal sheets 120, 130. The slot 201 corresponds to the tab 112 of the antenna 100, and the bump 202 corresponds to the through hole 114. The width of the filling block 204 is slightly The distance between the support portion 1121 of the tab 112 and the first segment 121 of the second metal piece 120 is greater than the distance between the end of the catch portion 1122 and the first segment 121.

When assembled, the assembly 200 is located between the tab 112 of the antenna 100 and the second metal sheet 120. The catching portion 1122 of the tab 112 slides into the slot 201 from the open end of the slot 201 until it slides to the end of the slot. When the catch portion 1122 slides to the end of the slot 201, the bump 202 snaps into the through hole 114 of the first metal piece 110. At this time, the first, second, and third metal pieces 110, 120, and 130 of the antenna 100 surround the two side walls and the bottom of the assembly 200. The filling block 204 is located on the protrusion 112 and the second metal piece 120. Between the tabs 112 and the first, second, and third metal sheets 110, 120, 130, the portions that are in close contact with the assembly 200 are provided. The latching portion 1122 of the tab 112 protrudes into the slot 201 of the assembly 200, so that the antenna 100 is well fixed on the assembly 200 and is difficult to disengage. The bump 202 is then snapped into the through hole 114 to limit the antenna 100 so that it does not shift. When the antenna 100 needs to be detached from the assembly 200, the first metal piece 110 is pressed down, the bump 202 is removed from the through hole 114, and then the antenna 100 is slid so that the holding portion 1122 of the tab 112 is narrowed. The slot 201 moves toward the open end of the slot 201 until it slides out of the slot, further away from the assembly 200. At the same time, the third metal piece 130 serving as the radiation portion of the antenna 100 is located outside the assembly 200 without affecting the radiation performance of the antenna 100.

In other embodiments, the shape of the antenna may be changed, which may be any configuration in which the antenna ground portion is perpendicular to the radiating portion, and a tab is bent and bent on the antenna ground portion, and a through hole is opened. The shape of the assembly is matched with the antenna so that the assembly having the slot and the bump has at least two sides and the day The wires fit and support the antenna. The configuration of the tab cooperates with the slot to enable the tab to slide into the slot, and the position of the bump and the through hole cooperate with each other, so that the tab is inserted into the through hole when the tab is slid to the end of the slot, thereby The way the antenna and the assembly are firmly assembled.
