Description

Technical Field

[0002] The mushroom head antenna is a conical antenna commonly used in Wi-Fi routers, mobile phones and other communication devices. The mushroom head antenna looks like a mushroom, hence the name. The mushroom head antenna is generally composed of three parts: an RF connector, a radiating antenna vibrator and a shell. The RF connector is the part that connects the mushroom head antenna to the device. The radiating antenna vibrator is the core part of the mushroom head antenna. It can convert electrical signals into electromagnetic waves and transmit them into the air. The shell wraps and fixes the RF connector and the radiating antenna vibrator together to play a protective role. Compared with other antennas, the mushroom head antenna has a compact structure and convenient installation characteristics, which is suitable for narrowband communications and other fields.

[0003] However, the RF connector, radiating antenna vibrator and shell of the existing mushroom head antennas on the market mostly adopt a split structural design, and then are assembled together to form a whole. Since the outer shell cannot completely wrap the radiating antenna vibrator, the anti-fall performance is not ideal, resulting in the radiating antenna vibrator easily loosening during the collision, causing the solder joint between the radiating antenna vibrator and the RF connector to fall off, resulting in the mushroom head antenna having no signal, thereby affecting the radiation performance and service life of the mushroom head antenna. Utility Model Content

An open groove is recessed in the middle of the lower end wall of the injection molded shell. The lower end of the radio frequency connector is located in the open groove. The injection molded sleeve is wrapped around the outer peripheral wall of the injection molded shell, and the injection molded shell and the injection molded sleeve are both integrally formed by injection molding.

[0010] Optionally, a waterproof rubber ring is further included, which is detachably embedded in the waterproof groove, and the width of the waterproof rubber ring is greater than the width of the waterproof groove.

[0011] Optionally, the waterproof rubber ring is an O-shaped rubber sealing ring.

[0012] Optionally, the width of the waterproof groove ranges from 4.1 mm to 4.4 mm.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] The utility model provides a drop-resistant and waterproof mushroom-head antenna.

[0028] like Figures 1 to 6As shown, in one embodiment of the utility model, the anti-fall and waterproof mushroom head antenna includes a radio frequency connector 100, a radiating antenna vibrator 200, an injection molded shell 300 and an injection molded sheath 400, wherein the radiating antenna vibrator 200 is arranged at the upper end of the radio frequency connector 100, a first welding pin 201 is protrudingly provided at the lower end of the radiating antenna vibrator 200, and a second welding pin 101 is protrudingly provided at the upper end of the radio frequency connector 100, and the first welding pin 201 and the second welding pin 101 are connected to each other. The injection molded housing 300 is fixedly connected by welding, the shape of the injection molded housing 300 is a cone structure, the RF connector 100 and the radiating antenna vibrator 200 are both embedded in the injection molded housing 300, an opening groove 301 is recessed in the middle of the lower end wall of the injection molded housing 300, the lower end of the RF connector 100 is located in the opening groove 301, the injection molded jacket 400 is wrapped around the outer peripheral wall of the injection molded housing 300, and the injection molded housing 300 and the injection molded jacket 400 are both integrally formed by injection molding.

[0029] Specifically, the radiating antenna vibrator 200 is a cylindrical spiral coil. When a wireless signal enters the mushroom head, the metal coil converts the signal into an electromagnetic wave and radiates it outward. Since the metal coil is conical, it bends the signal downward so that it radiates at a wider angle. This angle can usually reach about 180 degrees in the horizontal direction and is relatively small in the vertical direction.

[0030] Specifically, the injection molded shell 300 is made of PP material, PP plastic, chemical name: polypropylene, English name: Polypropylene (abbreviated as PP), specific gravity: 0.9-0.91 g / cm3, molding shrinkage: 1.0-2.5%, molding temperature: 160-220°C, PP is a crystalline polymer, and the comprehensive performance of PP is better than that of PE material. PP products are light, tough and chemically resistant. It has good mechanical properties and good toughness, and is integrally molded with the RF connector and the radiating antenna vibrator by injection molding. The internal space of the radiating antenna vibrator is completely filled with the injection molded shell, and the outside of the RF connector and the radiating antenna vibrator is completely wrapped by the injection molded shell. In this way, the RF connector and the radiating antenna vibrator will not loosen easily, and the mushroom head antenna can be effectively protected from damage, which greatly improves the anti-fall performance of the mushroom head antenna and extends its service life.

[0031] Specifically, the injection-molded sheath 400 is formed by one-piece injection molding of PVC material, polyvinyl chloride (PVC in English). The weight of PVC material is relatively light, and PVC has excellent mechanical properties, and can maintain strength and toughness at low temperatures. The water pressure resistance, external pressure resistance, and impact resistance of PVC material are very high, and can maintain stable performance under various complex environmental conditions. It is not easy to deform, crack or break, has a long service life, and reduces maintenance costs. The PVC material has good stability during long-term use, has good anti-corrosion and wear resistance, and can maintain stable performance in various environments, further improving the anti-fall performance of the mushroom head antenna, avoiding the welding point between the first welding pin and the second welding pin from falling off, and can effectively protect the mushroom head antenna from damage, and the outer surface is smooth and beautiful.

[0032] Specifically, a waterproof groove 302 is recessed along the circumferential direction on the lower end wall of the injection-molded shell 300. When a small amount of water enters the mushroom head antenna from the bottom, the waterproof groove plays a role of storing water and waterproofing. The incoming water is stored in the waterproof groove, thereby effectively preventing the incoming water from further entering the RF connector and damaging the mushroom head antenna, thereby effectively improving the waterproof performance of the mushroom head antenna.

[0033] Specifically, it also includes a waterproof rubber ring 500, which is detachably embedded in the waterproof groove 302, and the width of the waterproof rubber ring 500 is greater than the width of the waterproof groove 302. The waterproof rubber ring is used to further improve the waterproof performance of the mushroom head and extend its service life.

[0034] Specifically, the waterproof rubber ring 500 is an O-shaped rubber sealing ring.

[0035] Specifically, the width of the waterproof groove 302 ranges from 4.1 mm to 4.4 mm.

[0036] Specifically, the outer diameter of the lower end of the injection-molded sheath 400 ranges from 27.4 mm to 27.8 mm, and the height of the injection-molded sheath 400 ranges from 30.2 mm to 30.4 mm.

[0037] Specifically, the upper end of the injection-molded sheath 400 is arranged in a circular arc curved surface structure, and the radius of the circular arc curved surface is 6.9 mm.

[0038] Specifically, the working principle of the mushroom head antenna is:

[0039] The main part of the mushroom head antenna is the metal coil built into the mushroom head. When the wireless signal enters the mushroom head, the metal coil converts the signal into electromagnetic waves and radiates it outward. Since the metal coil is conical, it bends the signal downward so that it radiates at a wider angle. This angle can usually reach about 180 degrees in the horizontal direction and is relatively small in the vertical direction. The mushroom head antenna has advantages in some specific application scenarios, such as indoor Wi-Fi networks, where it can provide better omnidirectional performance.

[0040] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
