Function and future development prospect of RF connector
RF connectors can be far and near in people's life, but they are inseparable from RF connectors in our daily life. They play an important role in our daily life, so we can master and understand RF connectors more.
In addition to realizing the requirements of general characteristics, RF connectors also have very key requirements, which are good touch, reliable work and convenient maintenance. Whether the RF connector works reliably or not will immediately endanger all the normal work of the airport power supply circuit, and even involve the misfortunes and blessings of all hosts. Therefore, the host power supply circuit has very strict requirements for the quality and stability of the RF connector.
Therefore, RF connector has the characteristics of high quality and high reliability, which makes it widely used in military system software such as airlines, aerospace, national defense and security.
There are three common categories of RF connectors: appearance design, structure and main purpose.
1. Appearance design
Ring RF connector
Mostly used for military equipment (e.g. airlines, aerospace)
(rectangular wave energy storage technology RF connector 200A, well-known brand: Shenglan)
Rectangular RF connector
Simple structure, mostly used for printed PCB circuit board of electronic products
2. Structure
Composition of fixed end RF connector (female contact - power socket) and free end RF connector (male contact - power plug). The power socket is fixed on the power consumption components according to its square (round) plate (some or welding methods are selected). The power plug is generally connected to the cable, and the butt joint of the power plug and power socket is completed according to the butt joint screw cap.
Structural features of RF connector: resistance to natural environment, interface type (rapid) docking, multi button (anti misinsertion), touch body
Three basic elements of RF connector: shell, conductor and insulator, and contact body riveted and butted with transmission line (single take-off and delivery is easy to solve common faults).
1) Shell
It refers to the casing, connecting screw cap and tail end accessories of socket plug.
The function of the casing is to maintain the internal components of RF connector such as conductor, insulator and touch body (collectively referred to as pin socket) from being damaged. The precise positioning key slot on the top ensures the accurate positioning of the power plug and power socket. The connecting screw cap is used for butt joint and separation of the power plug base. The tail end fittings are used to protect the connection between the transmission line and the contact body from damage and to fix the cable.
The shell has the function of magnetic shielding material, and the shielding ring can ensure the shielding ability of 360 ° interference signal.
The shell is generally made of aluminum alloy (machining, hot forging and aluminum die casting). Steel shell is mostly used for broken glass sealing welding and heat-resistant RF connector.
2) Conductors and insulators
The utility model is composed of a needle inserting conductor and an insulator, a socket inserting conductor and an insulator, an interface sealing body, a wire sealing body, etc.
Make the needle socket stable on the set position, and make each touch body and each touch body in the shell insulated from each other's electrical equipment.
The conductor and insulator plus interface sealing body and wire sealing body are used to obtain the sealing countermeasures, so as to improve the environmental resistance of RF connector.
Most conductors and insulators are made of thermosetting plastic, rubber and plastic products, and the interface sealing body and wire sealing body are made of silica gel die. It can be more integrated into the heat resistance, ultra-low temperature and flame retardancy of commodities, so as to ensure that the geometric dimensions of components are stable and reliable.
3) Touch body
The utility model is composed of a male touch body and a female touch body (also known as a needle and socket).
Welding, crimping, crimping and winding are common interface modes of touch body, and the key is to complete the docking of power circuit.
Pin socket is an important component of RF connector, which directly affects the stability of RF connector. Most of the needle sockets are made of alloy copper raw materials with excellent conductivity, and the surface is plated with gold to achieve the purpose of low contact resistance and corrosion resistance. Sockets generally include split slot type sockets, wire spring sockets, crown spring sockets and punching sockets, etc.
3. Main purpose
Radio frequency connector, sealed radio frequency connector (glass sealing welding), high temperature radio frequency connector, etc.
Future development trend
In the future, with the development of science and technology, the high quality and reliability of RF connectors will grow to perfection in the high, precision and sharp industry.
1. Technical characteristics of RF connectors with high speed and high frequency
With the prevalence of 5g network era, 5g high data information and high transmission requirements are doomed to require the upgrading of the characteristics of RF connectors. RF connector is responsible for the conversion of optical and electronic signals in 5g communication.
2. Develop RF connector technology with higher accuracy and lower cost
In the automobile trading market, automobile connector is a very large sales market, and vehicles have high requirements for safety factor. With the growth of pure electric vehicles, the requirements for precision and cost of RF connectors are becoming higher and higher, which makes RF connectors more popular.
3. Grow smaller, more convenient and fast RF connector technology
Previous RF connectors were used for many contacts and were mostly added to the expansion card slot. During the growth of 5g period, an optical fiber device is likely to have dozens of RF connectors, which makes the RF connectors more sophisticated and capable of docking with excellent performance.
RF connector In the period of rapid development here, we must follow the pace and update and upgrade in order to better solve the challenges in the future. The growth of RF connectors is also to better and stronger, so as to ensure the quality of people's life. For example, Shenglan equity keeps pace with the times on the road of making RF connectors, and produces a variety of high-quality RF connector commodities up to more than 500000 yuan, which is one of the key sources of RF connector production and manufacturing.
Shenglan Technology Co., Ltd_ It focuses on the production of electronic connectors and research and development of precision components. Its products are widely used in consumer electronics, new energy vehicles, USB, 5g and other fields. Its industrial lines cover the Pearl River Delta, Southeast Asia and other regions. It has established long-term strategic cooperation relations with well-known enterprises such as Foxconn, Lixun precision, Huawei, Xiaomi, TCL, Hitachi Group, BYD and Great Wall Motors, with IATF 16949, ISO9001 ISO14001, QC080000 and other system certification and product safety certification, and provide professional connection and manufacturing solutions for the industry http://jctc.com.cn/
