Description

Technical Field

[0001] The utility model relates to the technical field of antenna devices, in particular to an antenna structure. Background Art

[0002] An antenna is a device used to send or receive radio frequency electromagnetic waves. Its function is to convert electrical energy into radio waves or convert radio waves into electrical energy. Antennas are usually composed of one or more metal conductors, which can be straight, curved, circular or other shapes. There are various types of antennas according to their design and purpose. Antennas can be divided into transmitting antennas and receiving antennas according to their purpose. Transmitting antennas are used to convert electrical signals into radio waves and send them out, while receiving antennas are used to receive radio waves and convert them into electrical signals. According to the operating frequency and directionality, antennas can also be divided into omnidirectional antennas and directional antennas.

[0003] In the current antenna structure, the conductor of the shielding layer and the conductor of the center electrode face in the same direction. This structure makes it inconvenient to electrically connect the conductor of the shielding layer to the circuit board when the antenna structure is welded to the circuit board. Moreover, the physical positions of the conductor of the shielding layer and the conductor of the center electrode are relatively close, and it is easy to short-circuit the two when they are welded separately. In addition, the electrical connection between the conductor of the shielding layer and other parts is a rigid connection, and long-term use may cause the electrical connection of the conductor of the shielding layer to fall off, resulting in poor contact with the circuit board, etc. Therefore, the utility model proposes an antenna structure to at least partially solve the problems that may exist in the prior art.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the adsorption diagram in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the adsorption diagram here can be arranged and designed in various different configurations.

[0044] In the following, some embodiments of the present application are described in detail in conjunction with the adsorption diagram. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0045] Please refer to Figure 1 to Figure 2 As shown, an embodiment of the utility model provides an antenna structure, including: a center pole 1, a shielding pole 2, and a tilted pole 3 are successively shortened from the inside to the outside, and are nested; a threaded sleeve assembly 4 is sleeved on the outside of the tilted pole 3; insulators are provided at the positions where the center pole 1, the shielding pole 2 and the tilted pole 3 contact each other, so that the conductors between the center pole 1 and the shielding pole 2 and between the shielding pole 2 and the tilted pole 3 are independent and will not be electrically connected, that is, the metal of the center pole 1 is not electrically connected to the conductor of the shielding pole 2, and similarly, the conductor of the tilted pole 3 is electrically connected to the conductor that is not electrically connected to the shielding pole 2; the threaded sleeve assembly 4 has an end portion provided with a mounting thread 402, and a side surface of the other end thereof is provided with a through hole 403; the through hole 403 is provided with a needle tube 5; a spring 6 is sleeved in the needle tube 5; wherein the needle tube 5 and the spring 6 are both conductors, and the other end of the spring 6 abuts against the conductor of the shielding pole 2.

[0046] In the present application, by setting a through hole 403 on the side of the threaded sleeve assembly 4, and setting a needle tube 5 and a spring 6 in the through hole 403, the spring 6 can be electrically connected to the conductor of the shielding electrode 2, and the spring 6 is set in the needle tube 5, and the outer tube tail plug is also a conductor, so that the needle tube 5 is electrically connected to the conductor of the shielding electrode 2, so that the direction angle between the center electrode 1 and the needle tube 5 is at a right angle.

[0047] The threaded sleeve assembly 4 and the related needle tube 4 and spring 6 combination introduced solve the problem of connection falling off that may occur when the conductor of the shielding layer and other parts are electrically connected in a rigid manner. The electrical connection structure realized by the spring 6 makes the electrical connection of the shielding layer have a certain elasticity (i.e., a flexible connection), which can alleviate the problem caused by loose connection to a certain extent. Specifically, the shielding pole 2 is connected to the needle tube 5 at the tail position of the outer tube of the threaded sleeve assembly 4 by using the flexible contact mode of the spring 6 and the needle tube 5 to form electrical conduction. The needle tube 5 is tightly fitted with the threaded sleeve assembly 4, and the spring 6 is in a compressed state in the needle tube 5. The two ends of the spring 6 are flexibly in contact with the conductor of the shielding pole 2 and the needle tube 5, respectively, and can be in permanent close contact to ensure stable signal transmission.

[0048] Next, an antenna structure in this exemplary embodiment will be further described.

[0049] In the embodiment of the present application, in the above antenna structure, refer to Figure 3 As shown, the center pole 1 includes a copper center needle 101, one end of which has at least one step; an insulating first sleeve, which is adapted to the shape of the center needle 101 and is sleeved on the outside of the center needle 101, and the other end of the center needle 101 protrudes from the end of the first sleeve. The center needle 101 is a conductor, serving as the main signal transmission part of the antenna structure, and is isolated from the outside by the insulating first sleeve, wherein the center needle is preferably made of copper material, so that it has good conductivity to ensure better signal transmission.

[0050] Further, see Figure 3 and Figure 4As shown, the first sleeve includes a needle sleeve 103 and a needle body sleeve 102, the needle sleeve 103 is sleeved on one end of the center needle 101, the needle body sleeve 102 is sleeved on the middle part of the center needle 101, and one end of the needle body sleeve 102 is connected to the needle sleeve 103, and the other end of the center needle 101 protrudes from the other end of the needle body sleeve 102, wherein the needle sleeve 103 is made of ABS plastic, wherein ABS (acrylonitrile-butadiene-styrene copolymer) has high strength and rigidity, and can be manufactured into parts of various shapes and sizes by injection molding and the like, and is suitable for large-scale production, and the ABS material has a smooth surface and high gloss, and is easy to be surface treated, such as painting, chrome plating, etc., and has good aesthetics, and also has good impact resistance, is not easy to break or deform, and has good tolerance, is not easily susceptible to chemical corrosion, and is suitable for use under a variety of environmental conditions.

[0051] In order to further improve its performance, a combination of ABS+PC+30%GF can also be used to replace the above-mentioned ABS parts. For example, multiple insulating parts in the above-mentioned antenna structure can be made of the above-mentioned ABS+PC+30%G three materials. Among them, the ABS+PC+30%GF material combination is a composite material composed of ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate) and 30% glass fiber reinforcement, which has higher strength and rigidity. Compared with pure ABS or PC materials, it is more impact-resistant and tensile-resistant. It is not easy to soften or deform in a high temperature environment and maintains stability, thereby ensuring that when the antenna works at a high frequency signal, a large amount of heat is generated and the insulating part will not soften or deform. In addition, the composite material also has a lighter weight, which is beneficial to reduce the overall weight of the product and reduce costs and transportation costs. The above-mentioned needle body sleeve 102 is made of Teflon. The above-mentioned Teflon has excellent high temperature resistance, can work in a high temperature environment for a long time, is not easy to melt or deform, has an extremely low friction coefficient, a smooth surface, good inertness, is not easily chemically corroded, and is suitable for use in various chemical environments. It is also an excellent electrical insulating material with good electrical insulating properties.

Figure 5 and Figure 6 The shielding plastic tube body 203 shown can be set as two sections, one of which is connected to the shielding plastic tube head 202, and the other section is aligned with the end of the shielding copper tube 201. The two sections of the shielding plastic tube body 203 are not connected in the middle, so that the shielding copper tube 201 is partially exposed from the shielding plastic tube body 203, and the inclined pole 3 covers at most the end of the shielding plastic tube body 203 connected to the shielding plastic tube head 202. The uncovered shielding copper tube 201 corresponds to the through hole 403 on the threaded sleeve assembly 4, so that the shielding copper tube 201 can be electrically connected to the above-mentioned needle tube 5 through the above-mentioned spring; the stability of the electrical connection between the shielding copper tube 201 and the needle tube 5 can be guaranteed by the spring.

[0054] In the embodiments of this application, refer to Figures 9 to 13As shown, the threaded sleeve assembly 4 includes: a threaded outer sleeve 401, an outer groove 412 is provided between the first end 411 and the second end 413; the end of the first end 411 is provided with the mounting thread 402, the second end is provided with a first hole 431 constituting the through hole 403, and an opening 414 is radially provided; a thimble plastic tube 404, a second hole 441 constituting the through hole 403, and a protrusion 442 corresponding to the opening 414; an outer tube tail plug, It includes a first tail plug tube 443, an inner groove 446 and a second tail plug tube 445 that are integrally arranged; a third hole 447 is provided on the first tail plug tube 443; the ejector plastic tube 404 is sleeved in the threaded outer sleeve 401, and the protrusion 442 is located in the opening 414, and the first tail plug tube 443 and the inner groove 446 are sleeved in the ejector plastic tube 404; the first hole 431, the second hole 441 and the third hole 447 constitute the through hole 403.

[0055] In the present application, a flexible contact method of a stainless steel spring 6 and a needle tube 5 is used to connect the shielded copper tube 201 and the threaded outer sleeve 401 through an outer tube tail plug, so that the shielded copper tube 201 and the threaded outer sleeve 401 are electrically connected through the spring 6 and the needle tube 5; the needle tube 5 is in close contact with the threaded outer sleeve 401, and the spring 6 is in a compressed state in the needle tube 5. The two ends of the spring 6 are in flexible contact with the shielded copper tube 201 and the needle tube 5 respectively, which can be permanently in close contact and the signal transmission is stable; a rigid connection method of the outer tube tail plug and the outer copper tube 302 of the inclined pole 3 is used to facilitate the circuit on the outer copper tube 302 to be led to the circuit board; the third hole 447 opened on the side of the outer tube tail plug allows the shielded copper tube 201 and the threaded outer sleeve 401 to be connected through the spring 5 and the needle tube 5 through the outer tube tail plug to form a loop, while shielding the signal transmission of the center needle and the outer copper tube 302 from signal interference; wherein, the outer copper tube 302 and the outer tube tail plug are rigidly connected, so that the outer tube is firmly assembled and does not fall off.
