[embodiment]

Fig. 1 is to the antenna module 1 that provides according to preferred embodiments of the present invention is provided.

Antenna module 1 comprises antenna 100 and the insulation connecting piece 200 of assembling with antenna 100.

Antenna 100 is made by a sheet metal integrated punching, and L shaped the second sheet metal 120 that it comprises the first sheet metal 110 of being positioned at the first plane, extend upward from the first sheet metal 110 1 sides and the cardinal principle that extends upward from the second sheet metal 120 are perpendicular to the 3rd sheet metal 130 on first plane at the first sheet metal 110 places.The second sheet metal 120 comprises perpendicular to the first paragraph 121 on the first plane and from the first paragraph 121 extended second segments 122 that are parallel to the first plane.Therefore the second sheet metal 120 and the 3rd sheet metal 130 form stepped.The first sheet metal 110 is as the grounding parts of antenna 100, and the intermediate position cutting forms a sheet metal, and sheet metal upwards is bent to form a L shaped lug 112.Lug 112 comprises perpendicular to the support portion 1121 on the first plane and the holding section 1122 that is parallel to the first plane.The first sheet metal 110 also comprises a rectangular through-hole 114, is positioned at a side of lug 112.The second sheet metal 120 is as the connecting portion of antenna 100, and the 3rd sheet metal 130 is as the Department of Radiation of antenna 100.

Connecting piece 200 is plastic cement material, its shape cooperates with antenna 100 and electronic equipment internal environment, comprise that one has the slit 201 of openend and backstop end, one is positioned at the projection 202 of bottom, and a pair of installing hole 203 is used for connecting piece 200 is fixed in the filling block 204 of electronic equipment and a strip.For cooperating antenna, connecting piece 200 also has a cascaded surface 205, with second, third sheet metal 120,130 of fitting.Wherein slit 201 is corresponding with the lug 112 of antenna 100, and projection 202 is corresponding with through hole 114.The width of filling block 204 is slightly less than the distance of the first paragraph 121 of the support portion 1121 of lug 112 and the second sheet metal 120, and distance terminal greater than holding section 1122 and first paragraph 121.

During installation, connecting piece 200 is between the lug 112 and the second sheet metal 120 of antenna 100.The holding section 1122 of lug 112 slides into slit 201 from the openend of slit 201, until slide to the end of slit.Projection 202 snaps in the through hole 114 of the first sheet metal 110 when holding section 1122 slides to slit 201 end.At this moment, first, second, third sheet metal 110 of antenna 100,120,130 and lug 112 with the two side of connecting piece 200 and bottom part ring around, filling block 204 is between lug 112 and the second sheet metal 120, so that lug 112 and first, second, third sheet metal 110,120,130 all have the part of being close to connecting piece 200.The holding section 1122 of lug 112 protrudes in the slit 201 of connecting piece 200, so that antenna 100 well is fixed on the connecting piece 200, is difficult to break away from.Projection 202 snaps in the through hole 114 again, and antenna 100 is spacing, and it can be subjected to displacement.When needs are dismantled antenna 100 from connecting piece 200, press the first sheet metal 110 downwards, projection 202 is shifted out from through hole 114, then antenna 100 slides, 201 openend moves along slit 201 to slit in the holding section 1122 that makes lug 112, until skid off slit, further break away from connecting piece 200.Simultaneously, the 3rd sheet metal 130 that is used as antenna 100 Departments of Radiation is positioned at connecting piece 200 outsides, can not affect the radiance of antenna 100.

Among other embodiment, the shape of antenna can change, and it can be antenna grounding portion any one configuration vertical with Department of Radiation, and cutting bends out a L shaped lug perpendicular to grounding parts on the antenna grounding portion, and offers a through hole.The shape of connecting piece cooperates with antenna, can at least three be posted by antenna loop and closes so that have the connecting piece of slit and projection, by lug is slipped into slit, thereby projection embeds through hole antenna and connecting piece is firmly assembled.
