[0033] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] like Figures 1 to 5 As shown, an embodiment of the present invention provides a quick-connect antenna structure, including an antenna component 1 and a female connector component 2;

[0035] The antenna component 1 includes an antenna plate 11, a female pin assembly 12, a plug socket 13 with a first through hole 131, and a housing 14 with an internal space 141. The antenna plate 11 is installed in the internal space 141, the female pin assembly 12 is installed in the first through hole 131 and the internal space 141, the plug socket 13 is inserted into the internal space 141, the antenna plate 11 is electrically connected to the female pin assembly 12, and the plug socket 13 is used to seal the internal space 141.

[0036] The female connector component includes an elastic element 21, an RF head 22, and a support 23 with a slot 231. The RF head 22 is mounted on the support 23 and extends into the slot 231, and the elastic element 21 is mounted on the support 23 and extends into the slot 231.

[0037] When the antenna component 1 is installed on the female connector component 2, the plug 13 is inserted into the slot 231, the elastic element 21 is inserted into the limiting side groove 132, and the radio frequency head 22 is electrically connected to the female pin assembly 12.

[0038] The antenna board 11 is a circuit board; the plug 13 is inserted into the bottom of the internal space 141 and is used to seal the opening at the bottom of the internal space 141; multiple limiting side grooves 132 and elastic elements 21 can be provided according to actual needs, and the elastic elements 21 are used to be inserted into the limiting side grooves 132 one by one; the elastic elements 21 include, but are not limited to, elastic glass beads, elastic pins, etc.

[0039] Specifically, when the antenna component 1 is installed on the female connector component 2, the plug 13 is inserted into the slot 231 and presses against the elastic element 21. The elastic element 21 is inserted into the limiting side groove 132, and the RF head 22 extends into the first through hole 131 and is electrically connected to the female pin assembly 12, thereby electrically connecting the RF head 22 to the antenna plate 11 through the female pin assembly 12. When the antenna component 1 is removed from the female connector component 2, the plug 13 can press against the elastic element 21 to make the elastic element 21 exit the limiting side groove 132, and the plug 13 is pulled out of the slot 231, separating the female pin assembly 12 from the RF head 22. In this utility model, the disassembly and assembly operations between the antenna component 1 and the female connector component 2 are convenient; furthermore, the quick-connect antenna structure is compact and occupies little space.

[0040] In one embodiment, such as Figure 1 As shown, the elastic element 21 is an elastic glass bead, and the support 23 is also provided with a side hole 232, in which the elastic glass bead is installed.

[0041] The side hole 232 penetrates the side wall of the support 23, and the rounded end of the elastic glass bead is located in the slot 231.

[0042] In this embodiment, the elastic glass bead is a standard part, which does not require separate design and manufacturing, further reducing the manufacturing cost of the quick-connect antenna structure.

[0046] Specifically, when the antenna component 1 is installed on the female connector component 2, the RF head 22 extends into the inner hole of the elastic sleeve and presses against the intermediate cylinder 152. The rebound force of the elastic part in the middle of the intermediate cylinder 152 causes it to make close contact with the external thread 221 of the RF head 22. Thus, the contact between the external thread 221 and the elastic sleeve 152 completes the electrical connection of the negative terminal or ground terminal of the quick-connect antenna structure, and the contact between the RF head 22 and the female pin assembly 12 completes the electrical connection of the positive terminal of the quick-connect antenna structure. In addition, the elastic force of the elastic sleeve ensures that it makes close contact with the external thread 221, guaranteeing the stability of the antenna component 1 installed on the female connector component 2.

[0050] Specifically, when the top of the radio frequency head 22 is inserted into the elastic sleeve 15, the protruding male pin 222 is inserted into the second through hole 1231 and contacts the conductive female pin 122, thereby completing the electrical connection between the protruding male pin 222 and the conductive female pin 122, and ensuring the stability of the electrical connection between the protruding male pin 222 and the conductive female pin 122.

[0051] In one embodiment, such as Figures 1 to 4 As shown, the female needle assembly 12 also includes a female needle sleeve 124, which has an insertion through hole 1241 and a receiving groove 1242 communicating with the insertion through hole 1241.

The radio frequency cable 121 and the insertion through hole 1241 are interference-fitted, and the insulating cylinder 123 and the receiving groove 1242 are interference-fitted.

[0054] In this embodiment, the design of the female needle sleeve 124 ensures the stability of the connection between the radio frequency cable 121 and the antenna plate 11 and the conductive female needle 122.
