Problems solved by technology

[0003] At present, SMA coaxial connectors are mostly used in radio frequency connectors, but the connection method of this coaxial connector is threaded connection. The threaded connection method is not suitable for vehicle applications, because the road conditions of the car are very complicated during driving. The vibration is very severe. During the vibration process, the threaded connection is easy to loosen and fall off, resulting in poor contact, unstable or no signal, and unreliable mechanical properties.
The threaded connection still needs to be tightened, which is a waste of time and does not have the characteristics of quick connection; the specific structure is as follows: Image 6
[0004] The FAKRA coaxial connector is mostly used in the vehicle coaxial connector. Although the FAKRA coaxial connector has a buckle to prevent loosening or falling off due to vibration, the connector uses hardware placed inside the mold. The production process of internal injection molding has many parts, complex production process, high defect rate, high production cost, and the buckle structure is a plastic part, the plastic part is easy to age during use, and there is still the possibility of mechanical failure during long-term use; The specific structure is as Figure 7

Embodiment 1

[0036] This embodiment provides a radio frequency coaxial connector, including: a female connector 1 and a male connector 2; the female connector 1 includes:

[0037] The shell has a snake-shaped buckle 101 on it, which is locked with the pin 201 of the male connector 2 under the action of the spring 102, and locks the pin 201 on the male connector 2;

[0038] The female pin 105 is connected to the male pin 205 of the male connector 2 at one end, and connected to the antenna at the other end;

[0039] The insulator I 107 is wrapped around the female pin 105 to prevent the shell from short-circuiting with the female pin 105, and cooperates with the female pin 105 and the shell to ensure that the RF coaxial connector reaches 50 ohm electrical performance;

[0040] The spring 102 acts as a lock to keep the serpentine buckle 101 and the pin 201 in a tensioned state;

[0041] There is a circle of embossing 106 on the periphery of the female connector 1, and the embossing 106 plays...

Embodiment 2

[0051] This embodiment provides another radio frequency coaxial connector, including: a female connector 1 and a male connector 2; the female connector 1 includes:

[0052] The shell has two snake-shaped buckles on it, and the two snake-shaped buckles are processed integrally with the shell, and the two snake-shaped buckles clamp the two pins on the male connector 2;

[0053] The female pin 105 is connected to the male pin 205 of the male connector 2 at one end, and connected to the antenna at the other end;

[0054] The insulator I 107 is wrapped around the female pin 105 to prevent the shell from short-circuiting with the female pin 105, and cooperates with the female pin 105 and the shell to ensure that the RF coaxial connector reaches 50 ohm electrical performance;

[0055] The spring 102 plays the role of locking, keeping the two serpentine buckles and the two pins in a tensioned state;

[0056] There is a circle of embossing 106 on the periphery of the female connector 1,...

Embodiment 3

[0066] A vehicle-mounted antenna includes the radio frequency coaxial connector described in Embodiment 1 or Embodiment 2.

[0067] The SMA coaxial connector in the prior art adopts the thread A connection; the FAKRA coaxial connector adopts the plastic buckle B connection, both of which have certain disadvantages; , Poor contact of the coaxial connector due to vibration. The invention not only provides stable and reliable electrical connection, but also has simple structure, small volume and few parts, thereby reducing cost.

[0068] In this application, the male connector can be at an angle of 90 degrees or 180 degrees, and can be welded to the main board by SMT, or can be welded to the main board by other methods. There is also a cable behind the female connector, and the cable is coax. The male connector can have male pins inside, or it can be made into a reverse polarity connector with female pins inside; if the male connector has female pins inside, the matching female...

Abstract

The invention provides a radio frequency coaxial connector and a vehicle-mounted antenna. The radio frequency coaxial connector comprises a female connector and a male connector. The female connectorcomprises a housing, a spring, a female pin and an insulator (I). The housing is provided with a serpentine buckle. The spring, the female pin and the insulator (I) are arranged in the housing. The insulator (I) wraps around the outer periphery of the female pin. The male connector comprises a body, a pin, a male pin and an insulator II. The insulator II wraps around the outer periphery of the male pin. The male pin is electrically connected with the female pin, and the pin is arranged on the body; The pin fits the serpentine buckle of the female connector and is locked with the female connector under the action of the spring. The radio frequency coaxial connector has the advantages of simple structure, stable connection, reduced size and reduced number of parts so that the manufacturing cost can be saved and mass production can be realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted antennas and vehicle-mounted electronic equipment, and specifically relates to a radio frequency coaxial connector and a vehicle-mounted antenna. Background technique [0002] RF radio frequency coaxial connector assemblies have been used in many applications, including routers, televisions, mobile phones, tablet computers and many other devices that have RF radio frequency coaxial connector assemblies. With the development of information technology, the automobile industry is also equipped with more and more information equipment, and more and more RF radio frequency coaxial connector components are needed. Due to the complex environment and severe vibration of automobiles, it is very important for stability. Therefore, many RF coaxial connectors widely used in other fields are not suitable for direct use on automobiles. At present, only FAKRA RF coaxial connectors are widely used in auto...
