The supporting portion 230 contacts with the upper surface of the mounted body 400, so that the position of the entire elastic contact portion 210 is raised, the deformation of the elastic contact portion 210 is increased, the pressure applied to the lower surface of the mounted body 400 by the rising section 212 is further increased, and the connection between the end of the mounting unit 200 and the mounted body 400 is more stable and reliable.

Preferably, the supporting portion 230 may be a supporting point, which forms a point contact with the upper surface of the mounted body 400, so that a stable connection between the mounting unit 200 and the mounted body 400 can be ensured through the point contact even if there is undulation of the upper surface of the mounted body 400.

More preferably, the number of the support points is two, and three-point support can be formed with the elastic contact portion 210, so that the connection stability between the attachment unit 200 and the attached body 400 can be maintained.

According to another embodiment of the present invention, as shown in fig. 1 to fig. 6, one end of the mounting unit 200 is provided with a first through hole 220, the fastening member is a fastening screw 300, the buckle 100 is provided with a threaded hole 111 corresponding to the fastening screw 300, and the fastening screw 300 sequentially passes through the first through hole 220 and the threaded hole 111 to fixedly connect the mounting unit 200 and the buckle 100. The screw hole 111 corresponding to the fastening screw 300 is directly formed in the buckle 100, so that a nut is not required to be additionally arranged, and the installation cost can be further reduced.

In accordance with another embodiment of the present invention, as shown in fig. 4 to 6, the buckle 100 includes a base plate 110 and two guide portions 120,

the base plate 110 is provided with a threaded hole 111, the base plate 110 further comprises at least two extending portions 112 formed by extending outwards in opposite directions,

the two guide portions 120 are symmetrically disposed with respect to a plane on which a central axis of the fastening screw 300 is located (i.e., a plane passing through the central axis of the fastening screw and perpendicular to the paper surface in fig. 3 and 4), the guide portions 120 include a connection portion 121, a positioning portion 122, and an elastic deformation portion 123, one end of the connection portion 121 is connected to the base plate 110, the other end thereof extends downward, the positioning portion 122 is connected to the connection portion 121 and abuts against the fastening screw 300,

the elastic deformation part 123 is connected with the connection part 121, can deform in the direction of the fastening screw 300, and is provided with a clamping part for clamping with the first mounting hole 410;

the elastic deformation portion 123 deforms in the direction of the fastening screw 300, so that the buckle 100 can be inserted into the first mounting hole 410 until the engaging portion of the elastic deformation portion 123 engages with the first mounting hole 410, and at this time, the extending portion 112 engages with the upper surface of the mounted body 400, thereby achieving the fixed connection between the end of the mounting unit 200 where the buckle 100 is disposed and the mounted body 400. Since the positioning portion 122 abuts against the fastening screw 300, the connection portion 121 and the elastic deformation portion 123 are restricted from being deformed in the direction of the fastening screw 300, and the difficulty of the clip 100 being pulled out from above is increased.

The elastic deformation portion 123 may be deformed by directly receiving a manual force, or may be inwardly deformed by a force applied to a sidewall of the first mounting hole 410 during the insertion of the clip 100 into the first mounting hole 410.

With such a structure, as shown in fig. 3, the relative distance between the two elastic deformation portions 123 in the horizontal direction (i.e., the X-X direction shown in fig. 4) gradually increases from bottom to top, so that only a downward force needs to be applied to the buckle 100, and with the insertion of the buckle 100, the side wall of the first mounting hole 410 applies a pressure to the elastic deformation portion 123 toward the fastening screw 300, and the elastic deformation portion 123 gradually contracts inward until the concave portion 1231 abuts against the first mounting hole 410, thereby achieving the snap fit between the mounted body 400 and the buckle 100.

Further, the concave part 1231 further comprises an abutting surface 1231 'and an anti-falling surface 1231 ", the lower end of the abutting surface 1231' is connected with the upper end of the anti-falling surface 1231", an included angle between the anti-falling surface 1231 "and the horizontal direction is smaller than 45 °, and the buckle 100 is effectively prevented from being pulled out from the upper side.

Further, the number of the extending portions 112 may be 4, 6, 8, etc., as long as two extending portions are symmetrically disposed, the upper limit of the number of the extending portions 112 is not particularly limited, and as long as there are two extending portions 112 extending outward in opposite directions, the buckle 100 can be ensured to be stably contacted with the upper surface of the mounted body 400, and will not be separated from the lower portion of the first mounting hole 410. Preferably, the extensions 112 need to be symmetrically disposed.

According to another embodiment of the present invention, the elastic deformation portion 123 includes a guiding surface 1232 for guiding, and the cross section of the guiding surface 1232 perpendicular to the axial direction of the fastening screw 300 is a convex arc surface facing away from the fastening screw 300. Therefore, the clip 100 is always in point contact with the first mounting hole 410 during the insertion process into the first mounting hole 410, which can reduce the friction force during the insertion process and facilitate the insertion of the clip 100.

According to another embodiment of the present invention, the connecting portion 121 is provided with an opening 1211, which can reduce the weight of the buckle 100 and further reduce the weight of the product to be mounted.

Further, there is no particular limitation on the structure of the positioning portion 122, as long as one end is connected to the connecting portion 121 and abuts against the screw rod of the fastening screw 300, so as to limit the deformation of the connecting portion 121 in the direction of the screw rod, according to another embodiment of the present invention, one end of the positioning portion 122 is connected to the connecting portion 121, and the other end extends in the direction of the fastening screw 300 and abuts against the fastening screw 300.

According to another embodiment of the present invention, the present invention further provides an antenna module, which includes an antenna unit 500 and any one of the aforementioned fixing components, wherein the antenna unit 500 is used for sending and/or receiving signals, and the antenna unit 500 is fixedly connected to the mounting unit 200.
