Description

Technical Field

[0001] The present application relates to the field of built-in router antennas, and in particular to an integrated sheet metal formed built-in router antenna. Background Art

[0002] With the continuous advancement and development of network technology, the use and coverage of wireless networks have also been rapidly promoted and popularized. Clothing, food, housing, transportation, factory processing and production, and daily communications all require the use of the Internet. With the widespread use of smart phones, wireless networks have become particularly important. Whether it is home, shops or some public activity areas, there are wireless networks. In wireless network systems, routers are a very important electronic device. Its main function is to convert wired network signals into wireless signals for people to use.

[0003] A wireless router is a router with wireless coverage function, which is like an extended product that combines a simple wireless AP and a broadband router. It not only has all the functions of a simple wireless AP, such as supporting DHCP client, VPN, firewall, WEP encryption, etc., but also includes the network address translation (NAT) function, which can support network connection sharing for LAN users. It can realize Internet connection sharing in home wireless networks and realize wireless shared access of ADSL and community broadband.

[0004] In order to transmit and receive transmitted signals, the antenna is one of the necessary components of the wireless router. Existing antennas generally include internal antennas and external antennas. For external antennas, there are usually two antenna installation methods for fixing it to the main body of the electronic product: one is to directly fix the antenna to the main body of the electronic product with screws, and the other is to open a through hole on the main body of the electronic product and pass the antenna through the through hole. Both installation methods are not very good and have poor stability. In addition, wireless routers equipped with external antennas are gradually eliminated due to their large size. Internal antennas are gradually replacing external antennas because they are smaller in size than external antennas.

[0005] In the prior art, built-in antennas mainly include the following forms: FPC (flexible circuit) antennas, PCB antennas, stamped shrapnel antennas, and LDS (laser direct structuring) antennas. FPC antennas generally need to be pasted to internal structural parts, and generally require multiple antennas, making the assembly structure design complex; PCB antennas generally require welding of coaxial lines and then assembling them in different directions inside, so there are high requirements for structural design and internal wiring; traditional stamped shrapnel antennas generally require plastic brackets for support and are assembled by hot melting, with many processes; LDS antennas require special plastic particles, so the cost is relatively high.

[0035] In order to provide signals of multiple frequency bands and simplify the installation steps and reduce the cost during the installation process, the present application embodiment provides an integrated sheet metal formed internal router antenna, comprising: at least two antenna radiation units 1, wherein the plurality of antenna radiation units 1 are integrally formed of sheet metal.

[0036] The antenna radiation unit includes: a radiation base surface 11 and an antenna vibrator 12, the antenna vibrator 12 is arranged on the radiation base surface 11, the antenna vibrator 12 is bent into an inverted L-shaped structure to ensure that the antenna vibrator 12 is clear, the antenna vibrator 12 includes a vibrator horizontal portion 121 and a vibrator vertical portion 122, the vibrator horizontal portion 121 is connected to the radiation base surface 11 through the vibrator vertical portion 122.

[0037] A coaxial line routing area 111 and a coaxial line grounding wire clamp 112 are provided on the radiation base surface 11. The coaxial line routing area 111 is staggered with the horizontal portion 121 of the vibrator. One end of the coaxial line routing area 111 is in close contact with the vertical portion 122 of the vibrator. The coaxial line grounding wire clamp 112 is welded on the coaxial line, and the coaxial line grounding wire clamp 112 covers one end close to the coaxial line routing area 111.

[0038] The antenna vibrator 12 is provided with a coaxial line core wire welding point 123 and a coaxial line braided layer welding point 124, the coaxial line core wire welding point 123 includes a long groove 1231 arranged on the outside of the vertical part 122 of the vibrator, and a short groove 1232 arranged on the edge of the horizontal part 121 of the vibrator, the long groove 1231 and the short groove 1232 form an inverted L shape, the coaxial line braided layer welding point 124 is an arc-shaped groove, and is parallel to the short groove 1232, and a gap is formed between the coaxial line braided layer welding point 124 and the short groove 1232.

[0039] It should be noted that, in order to meet the requirements of multi-band signals and provide stronger signal strength, the number of antenna radiating units 1 provided in the embodiment of the present application is not limited to 2, and can also be 3, 4, 5, 6, 7, 8 or 9 antenna radiating units 1, as long as the number can meet the conditions for being installed in the router.

[0040] The antenna vibrator 12 is bent into an inverted L-shaped structure. The antenna vibrator 12 includes a horizontal vibrator portion 121 and a vertical vibrator portion 122. The horizontal vibrator portion 121 and the vertical vibrator portion 122 are perpendicular to each other, ensuring that the horizontal vibrator portion 121 is at a certain height from the radiation base surface 11 to ensure that the antenna vibrator 12 is clear.

[0041] The antenna radiation unit 1 provided in the embodiment of the present application is connected to the PCB board of the router through a coaxial line. The structure of the coaxial line is composed of four parts from the outside to the inside, namely, a sheath, an outer conductor layer, an insulating dielectric layer and an inner conductor. The coaxial line is a shielded and non-dispersive structure, and the main mode of the waveguide in the coaxial line is TEM wave, but TE mode and TM mode can also be transmitted at the same time, and its cut-off frequency is zero, and the corresponding cut-off wavelength tends to infinity. It is a dual-conductor transmission line composed of two coaxial inner and outer conductors and a dielectric in the middle. Generally, the outer conductor of the coaxial line is grounded, and the electromagnetic field is confined between the inner and outer conductors, so the coaxial line has basically no radiation loss and is almost not affected by external signals.

[0043] In addition, the radiation base surface 11 is provided with a coaxial line routing area 111 and a coaxial line grounding wire clamp 112. The coaxial line routing area 111 can facilitate the coaxial line after welding to pass through the coaxial line routing area 111, which can shorten the routing length as much as possible, avoid messy routing, and facilitate the layout of PBC components. The coaxial line grounding wire clamp 112 is welded on the coaxial line, and when routing, the coaxial line grounding wire clamp 112 is covered on the corresponding hole of the radiation base surface 11. The grounding wire clamp 112 can play a grounding function and shield the interference of external signals.

[0046] To facilitate routing, the coaxial cable routing area 111 is in the shape of a long hole, the area of ​​the hole close to the vertical portion 122 of the vibrator is smaller than the area of ​​the hole away from the vertical portion 122 of the vibrator, and the antenna terminal 13 is located directly below the hole away from the vertical portion 122 of the vibrator.

[0047] In addition, an assembly positioning hole 113 is also provided on the radiation base surface 11, and the assembly positioning hole 113 is staggered with the vibrator horizontal portion 121, and the assembly positioning hole 113 is circular or hexagonal in shape. The assembly positioning hole 113 can play a good fool-proof role.

[0048] In order to meet the needs of multi-band signals, the number of the antenna radiating units 1 is six, and the working frequency band of two adjacent antenna radiating units 1 among the six antenna radiating units 1 is in the WIFI 2.4GHz frequency band, and the working frequency band of four adjacent antenna radiating units 1 among the six antenna radiating units 1 is in the WIFI 5GHz frequency band. The six antenna radiating units 1 are connected end to end to form a regular hexagon.
