[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] Please refer to Figures 1 to 4 A radiation unit component comprises a mounting base 1, a feeding base plate 2, two radiation arms 3 and two feeding plates 4; the two radiation arms 3 are orthogonally arranged on the top of the mounting base 1, a protruding plug-in column 11 is provided on the top of the mounting base 1, at least one elastic clamping arm 12 is provided on the side of the plug-in column 11, and a socket 31 matching with the plug-in column 11 is provided on the radiation arm 3; the two feeding plates 4 are orthogonally arranged inside the mounting base 1; the feeding base plate 2 is arranged at the bottom of the mounting base 1; one end of the two feeding plates 4 is respectively connected to the radiation panel for feeding, and the other end of the two feeding plates 4 is respectively connected to the feeding base plate 2 for feeding.

[0027] From the above description, it can be seen that the beneficial effect of the utility model is that when the radiation arm 3 of the radiation unit assembly is assembled with the mounting base 1, the socket 31 of the radiation arm 3 is aligned with the plug-in column 11 of the mounting base 1, and then the plug-in column 11 is inserted into the socket 31 until the elastic clamping arm 12 passes through the socket 31 and contacts the upper surface of the radiation arm 3 to complete the assembly. There is no need to use additional fasteners, the assembly process is simple and convenient, and there is no need to make the radiation arm 3 bend significantly, which is not easy to cause deformation of the radiation arm 3.

[0028] Furthermore, the mounting seat 1 is provided with a protruding fool-proofing block 13 , and the radiating arm 3 is provided with a fool-proofing hole 32 matched with the fool-proofing block 13 .

[0029] It can be seen from the above description that the cooperation between the fool-proofing protrusion 13 and the fool-proofing hole 32 can limit the relative angle between the radiation arm 3 and the mounting seat 1 , which is conducive to accurate assembly of the radiation arm 3 and improved assembly efficiency.

[0030] Furthermore, a baffle 14 protruding upward is provided on the top of the mounting base 1 .

[0031] It can be seen from the above description that the baffle 14 is used to resist foreign objects to prevent the foreign objects from squeezing or colliding the connection between the feeding plate 4 and the radiation arm 3 and causing poor contact.

[0032] Furthermore, a plurality of clamping portions 15 are provided at the bottom of the mounting seat 1 , and the plurality of clamping portions 15 extend downward to form an insertion end 151 , and a protruding clamping block 152 is provided on the outer side surface of the insertion end 151 .

[0033] As can be seen from the above description, the clamping portion 15 is used to be inserted into the assembly hole of the reflector until the clamping block 152 contacts the back of the reflector, so that the radiation unit assembly is plugged into the reflector to fix the radiation unit assembly on the reflector.

[0034] Furthermore, the width of the insertion end 151 gradually decreases from one end close to the mounting seat 1 to the other end.

[0035] It can be seen from the above description that the structure of the insertion end 151 is more convenient for plugging and matching with the assembly hole of the reflector.

[0036] Furthermore, a window 153 is provided on the outer side surface of the insertion end 151 , and a protruding elastic arm 154 is provided on the inner circumference surface of the window 153 . The elastic arm 154 extends upward, and the block 152 is provided on the outer side surface of the elastic arm 154 .

[0037] It can be known from the above description that when the insertion end 151 is plugged into the reflective plate, the elastic arm 154 will be elastically deformed so that the clamping block 152 can pass through the assembly hole on the reflective plate.

[0038] Furthermore, the top end of the elastic arm 154 extends upward to form a pressing portion 155 .

[0039] From the above description, it can be seen that the pressing part 155 is exposed at the assembly hole of the reflective plate. By applying force to the pressing part 155, the elastic arm 154 is bent and deformed inward, so that the block 152 can pass through the assembly hole of the reflective plate, thereby facilitating the disassembly and assembly process of the radiation unit assembly on the reflective plate.

[0040] Furthermore, the feeding bottom plate 2 is provided with an avoidance hole 21 for the clamping portion 15 to pass through.

[0041] As can be seen from the above description, providing the avoidance hole 21 to allow the clamping portion 15 to pass through the feeding base plate 2 is conducive to making the structure of the radiation unit assembly more compact and meeting the development trend of product miniaturization.

[0042] Furthermore, a plurality of slots 16 are provided on the inner circumferential surface of the mounting seat 1 , and the two side edges of the feeding plate 4 are respectively disposed in the slots 16 .

[0043] It can be seen from the above description that the assembly method of the feeding plate 4 and the mounting base 1 is simple, which is conducive to improving the assembly efficiency.

[0044] Furthermore, the feed base plate 2 is provided with a plurality of mounting holes 22 .

[0045] It can be seen from the above description that the multiple mounting holes 22 can facilitate the fixed connection between the feeding base plate 2 and the external components.

[0046] Please refer to Figures 1 to 4, Embodiment 1 of the utility model is: a radiation unit assembly, including a mounting seat 1, a feeding base plate 2, two radiation arms 3 and two feeding sheets 4; the two radiation arms 3 are orthogonally arranged on the top of the mounting seat 1, a protruding plug-in column 11 is provided on the top of the mounting seat 1, at least one elastic clamping arm 12 is provided on the side of the plug-in column 11, and a socket 31 matching with the plug-in column 11 is provided on the radiation arm 3; the two feeding sheets 4 are orthogonally arranged inside the mounting seat 1; the feeding base plate 2 is arranged at the bottom of the mounting seat 1; one end of the two feeding sheets 4 is respectively connected to the radiation panel for feeding, and the other end of the two feeding sheets 4 is respectively connected to the feeding base plate 2 for feeding. Specifically, the mounting seat 1 includes a cylindrical base and a support platform connected to the top of the base, the support platform includes four support arms extending radially outward, the angle between two adjacent support arms is 90°, each support arm is respectively provided with a plurality of plug-in columns 11, and two elastic clamping arms 12 are provided on the side of each plug-in column 11, and the top of the elastic clamping arm 12 is connected to the top of the plug-in column 11. Each radiation arm 3 is respectively plugged with two support arms through plug-in columns 11 and elastic clamping arms 12. Four clamping grooves 16 are provided on the inner circumference of the base of the mounting seat 1, and the two side edges of the two feeding plates 4 are respectively arranged in a clamping groove 16. In this embodiment, the mounting seat 1 is preferably made of plastic.

[0047] The mounting base 1 is provided with a protruding fool-proofing protrusion 13, and the radiating arm 3 is provided with a fool-proofing hole 32 that matches the fool-proofing protrusion 13. Specifically, at least two adjacent support arms are provided with at least one fool-proofing protrusion 13 on their top surfaces. The number of fool-proofing protrusions 13 and fool-proofing holes 32 is set one by one.

[0048] A baffle 14 protruding upward is provided on the top of the mounting base 1. Specifically, a baffle 14 is provided between any two adjacent support arms, and the two ends of the baffle 14 are respectively connected to the two support arms. A protruding welding portion is provided on the top of the feed sheet 4, and a contact hole for plugging and matching with the welding portion is provided on the radiation arm 3. The maximum height of the baffle 14 is greater than the maximum height of the plug-in column 11 and the welding portion. The baffle 14 is used to resist foreign objects to prevent foreign objects from squeezing or colliding with the connection between the feed sheet 4 and the radiation arm 3, resulting in poor contact.

[0049] The bottom of the mounting seat 1 is provided with a plurality of clamping parts 15, which extend downward to form an insertion end 151, and the outer side of the insertion end 151 is provided with a protruding clamping block 152. Specifically, the clamping parts 15 are formed by extending downward from the bottom end of the base of the mounting seat 1, and there are four clamping parts 15. The mounting seat 1 and the clamping parts 15 are an integrated structure formed in one piece.

[0050] In order to facilitate the insertion end 151 to pass through the assembly hole on the reflector, the width of the insertion end 151 gradually decreases from one end close to the mounting seat 1 to the other end.

[0051] A window 153 is provided on the outer side of the insertion end 151, and a protruding elastic arm 154 is provided on the inner circumference of the window 153. The elastic arm 154 extends upward, and a block 152 is provided on the outer side of the elastic arm 154. Specifically, the window 153 communicates with the inner side and the outer side of the insertion end 151. The elastic arm 154 is vertically arranged, and the elastic arm 154 is formed by protruding upward from the bottom surface of the window 153. The bottom surface of the block 152 is set as an inclined surface to facilitate passing through the assembly hole of the reflector.

[0052] The top of the elastic arm 154 extends upward to form a pressing portion 155. After the insertion end 151 passes through the assembly hole of the reflector, the block 152 will abut against the inner side of the assembly hole of the reflector to prevent the insertion end 151 from exiting the assembly hole of the reflector, and the pressing portion 155 is exposed from the assembly hole. It is easy to understand that when the radiation unit assembly needs to be removed from the reflector, it is only necessary to apply pressure to the pressing portion 155 to bend the elastic arm 154 inwardly, and the block 152 no longer abuts against the inner side of the assembly hole, and the insertion end 151 can exit the assembly hole, thereby allowing the radiation unit assembly to be removed from the reflector.

[0053] The feed bottom plate 2 is provided with an avoidance hole 21 for the clamping part 15 to pass through. Specifically, the feed bottom plate 2 is arranged between two clamping parts 15, and the feed bottom plate 2 is provided with an avoidance hole 21 for the other two clamping parts 15 to pass through.

[0054] In order to facilitate the fixed connection between the feed base plate 2 and the external components, a plurality of mounting holes 22 are provided on the feed base plate 2 .

[0055] To sum up, when the radiating arm of the radiating unit assembly provided by the utility model is assembled with the mounting seat, the socket of the radiating arm is aligned with the plug-in post of the mounting seat, and then the plug-in post is inserted into the socket until the elastic clamping arm passes through the socket and contacts the upper surface of the radiating arm to complete the assembly. There is no need to use additional fasteners, the assembly process is simple and convenient, and there is no need to bend the radiating arm significantly, which is not easy to cause deformation of the radiating arm.
