Recently, Some users gradually choose SMB connectors because SMB series connectors can improve the consistency of the connector installation and their excellent performance, The SMB series can also be used in commercial and military.     In fact, The same application be selected through have many schemes, The user can choose the suitable connectors based on their demand.     Connection mechanism selection: Coupling mechanism make it possible to connect the two connector, It depends on the required mass and impedance characteristics of the two interfaces coupled together and the operation frequency. The connection mechanism has a great influence on the performance of the connector. Here are five common connection mechanisms.     Screwed Coupling Mechanism, This type of connect use a coupling nut to connect, It should be noted that the limitation of the maximum torque in case the nut slides, Connector with threaded connection mechanism have the series as below: SMC、SMA、N、7/16、SSMA、CC4、L9, TNC connector They mainly use in test equipment, military and telecommunication equipment.     Snap-on Coupling Mechanism: They are mainly used in connectors for small interfaces and their installation density is relatively high. Because this kind of connection mechanism is more convenient and easy to use, they’re usually used in the PCB panel.     The push-in connection has a locking reed: The advantages of them are the dialing is very quick and convenient, This type of bindiny mechanism is mainly used in miniature connector series, For example: SMB、SSMB、SMZ、MMCX、MCX connector.     Slide-on Coupling Mechanism usually used high density installation occasions: It’s very easy to plug and dial,This type of connector is mainly used in board – to – board coaxial connection systems. The connection mechanism is mainly used in small DIN multi-end connectors, For example: BMA、C4、C5、C6、ERI, They are usually modular installations.     Bayonet Coupling Mechanism, There are a pair of lock slots, this kind of locking mechanism is the unique feature for BNC connectors; Bayonet connection mechanism is usually used in applications where reliable connections are required and can be inserted quickly, For example: testing and measuring equipment and military equipment.     Push-Pull Self-Latching, This connection mechanism has a unique way of self-locking: It is as quick and convenient as a slip-in connection when plugged, but it is very reliable. When it locks itself, even a pull cable will not unlock.Push-in self-locks are typically used on small connectors in high-density installations such as: 1.0/2. 3,1.6/5.6 series. It is fast and reliable.

    Imagine what would happen if there were no connectors,At that time, We must use the continuous conductor to connect the electronic circuit. For example, If the electronic equipment need to be fixed on the power supply, We must use the sides of the connecting wire to be soldered between the electronic equipment and power supply which will bring many inconvenient for both the production and usage.     Take the LED landscape lamp as an example. It’s a long distance between the power supply and the lamp holder, If it’s the wire connected between each power supply and the lamp holder. It’ll bring many unnecessary trouble for the road work,and also can cause the waste of the wire. Some people may doubt that why not directly open a gap from the firing line, then connect the electric part together,and wrap several layers of insulating glue around it. There is no need to use the connector at all.     First, The insulating tape mostly easy to age, then exist safety risk, Secondly, The connector that directly combined with electric wire have terrible mechanical property, If the circuit slightly stretching vibration, It’ll be very easy to cause disconnection, and the heat. Then it’ll possible to cause the fire hazard, Besides, the outdoor environment is bad, waterproof and anti-salt anti-aging requirements will be relatively strict. Insulation adhesive is far from meeting the requirements, But if you use high performance waterproof connectors for outdoor lighting, It not only simplifies the installation of power grids and all these safety risks will be reduced to a very low level.     Take a sample example to explain the benefits of RF connectors, They make the design and production process more convenient, flexible, and safer, also reduce the production and maintain cost. The connectors improve the production, simplify the the assembly process of electronic products and the mass production, easy to maintain, If An electronic RF component fails to work, Failure element components can be replaced quickly when connectors are installed, it’s convenient for us to upgrade, With the development of technology, Meta data can be updated when connectors are installed, Replace the old with new more complete components to improve the flexibility of design, Using connectors enables engineers to design and integrate new products and when a system is composed of components it will be more convenient.     Especially for industrial connectors, Sometimes used in harsh environments where plugging is required, then flexibility and security are more important, a simple plug and pull connector with a buckle is a wise choice at this point.

    An important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability index. It is called "mechanical operation" in the national standard GB5095. It uses a single insert and a pull out as a cycle to judge whether the RF connector can normally complete its connection function after the specified plug and play cycle.     The insertion force and mechanical life of the connector are related to the contact structure of the contact, the quality of the coating, and the accuracy of the arrangement and dimension of the contact, The main electrical properties of electrical connectors include contact resistance, insulation resistance, and dielectric strength.     Contact resistance high quality electrical coaxial connectors should have low and stable contact resistance. The contact resistance of the connector varies from a few tens of tens to tens of ten cents.     The insulation resistance of the insulation performance indicators measure between the electrical connector contacts and contact with the shell, the order of the number of megabytes to several begohm ranging from europe.     Electrical resistance, or resistance to voltage, dielectric withstand voltage, is to describe the ability to withstand test voltage between connector contacts or between contacts and housings.     Electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of connectors, electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of connectors, and is generally tested in the frequency range of 100MHz~10GHz.     For RF coaxial connectors, there are also electrical characteristics such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing in Bobbi. Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signal, a new type of connector is high speed signal connector, the corresponding, in terms of electrical performance, in addition to the characteristic impedance, there are some new electrical indicators, such as crosstalk delay, Environmental performance, common environmental performance, including temperature, humidity, vibration and impact, etc.     The maximum working temperature of the connector is 200 DEG C, and the minimum temperature is -65 centigrade. The operation of the connector, the current heat generated in the contact point, resulting in a temperature rise, so that the working temperature should be equal to the ambient temperature and the temperature rise and contact. In some specifications, the maximum temperature rise permitted by the connector under rated operating current is specified.     The invasion of moisture resistance will affect the insulation performance of H and rust the metal parts. Constant humidity test conditions are rel...

    The connector and the binding head, also named as a receptacle, plug, or socket, English name is connector. specifically speaking, The connector is a device used to connect between the circuit conductors, transmission elements,In the two circuit subsystem, The rf connector provide a detachable interface, The interface should not have an unacceptable impact on the performance of the system, The connector here is normally mentioned as electric coupler, A device that connects two active devices. Which is used to transmit current or signals, normally fixed on the Cable (wire)or devices, A detachable device for electrical connection to a transmission system.     Electrical connector is a kind of component frequently contacted by electronic engineers, Their function os very simple, In the circuit is blocked or isolated between the circuit, they work as the bridge of communication, so as to make the current flow, the circuit to achieve the intended function. Electrical connectors perform electrical connections and signal transfer between devices and devices, components and systems, It is the basic element necessary to form a complete system, Connector is an indispensable part of electronic equipment. Looking down the current path, you can always find one or more connectors.     Connectors vary a lot in forms and structures, With the differences of application object, frequency, power, application environment and other factors, There will be various forms of coaxial connectors, For example: A connector for home wiring, Connectors for lighting on the court, Hard drive connectors, communication networks connectors, Fire the rocket’s connector, Connectors with different requirements and occasions differ greatly in appearance, structure, performance, indexes, etc, But no matter what kind of connector, it is necessary to ensure that the current or signal flowing through it smoothly, continuously and reliably,With the development of science and technology, especially in the rapid development of electronic technology today, Connectors connect to more than just current or simple signals,In optical fiber systems, the carrier of signals is light, and glass and plastic replace the wires in ordinary circuits, It can be transmitted over long distances, optical signal connectors play an important role in long-distance transmission,     In China, In the industry management, connectors, switches, keyboards and other components are collectively referred to as electrical connectors, At the same time, electrical connector and relay are collectively referred to as electromechanical components. With the development of consumer electronics, automotive electronics, communication terminal market, China has become the world’s fastest growing connector and the largest capacity market,they are mainly used in transportation, communication, network, IT, medical treatment, home appliances, instruments and meters and other fields...

    The effect of the connector terminals is the tool when connecting low-tension cable, wires with electrical equipment(normallytransformer, box, Cabinets ).     The connector terminal is used to connect the wire. In fact,It’s a metal scrapes which is sewn into insulating plastic, Both sides have the holes which can be connected with cables. The screw is used to tighten or loosen,Like the two cables, Sometimes they connect, sometimes they disconnect, The connector terminal is used to connect them together, can they cab be disconnected anytime, You don’t have to weld them together or wrap them together, It’s very convenient and fast.and very suitable for many cables connect together. In the electric power industry,There are Special connector terminal row,connector terminal box, It’s full of fakra connector terminals on them, Single or double,Current, common type, A certain area of compression is required to ensure reliable contact, And to be able to get enough current through.     The connector terminals is a kind of accessories to realize electrical connection.It’s divided into the connectors in the industrial engineering, With the increasing degree of industrial automation Industrial controls standards are becoming more stringent, precise, The amount of connector terminal is increasing gradually.     ①What is the condition to use connector terminal board?     Electrical connections between different devices need to use connector terminal board, Some plug-ins (modules) also require a connector terminal row.     ②When the wiring connector terminal board is used in the middle of the gas cabinet?     Take a installation unit as the boundary, ipex connector terminal rows are required to access and exit the unit.     ③What is the effect of the connector terminal board in the power distribution box?     connector terminals is the special for the ground electrode, At present, China’s electricity is three-phase four-wire system, The zero line is separated from the ground line,Ground wire is generally connected to the ground wire socket, in order to protect the safety of electricity!

    In today’s society, the development of science and technology is faster and faster, people also gradually to electronic, technology development, and electronic connector is such a new thing. At both ends of a loop, there are two conductors, and there may be no connection between the two conductors. The role of electronic connector is to make the two conductors well connected, so that different currents or communication signals can effectively flow between the two conductors.     It is widely used in all kinds of electrical engineering. And it is simple and convenient that we can make a temporary connection through electronic rf connector adaptor, which can be inserted and pulled at will to solve the problem for a while. It can also be a permanent connection in the middle of many electrical devices, or a permanent node can be established between different wires.     The material sort of electronic connector is very much, the connector of different sort, having different effect, the degree of difficulty of machining, also can affect the effect that USES greatly. The materials we use to make electronic coaxial connectors generally include materials that can be insulated such as plastic, and some materials that can conduct electricity, such as phosphorous copper or brass. When we choose electronic connectors with different functions, we should pay attention to the choice of appropriate products according to the specific situation.

    With the use of more and more electronic products, mobile phones, computers, cameras and so on, the demand for RF coaxial connectors is also increasingly high. At present, the top five application fields in global connector sales are automobile, computer and its peripherals, communication, industrial equipment, aerospace and military, while the top five applications in growth are consumer electronics, transportation electronics, medical electronics, communication electronics, computer and so on.     RF connector adaptor, as an indispensable part of electronic products, plays an increasingly important role in the diversified functions and modular design of electronic products.     The CAGR (annual compound growth rate) of China’s coaxial connector adaptor market in the past five years was 27.2%, and the CAGR in the past 10 years was as high as 42.7%, far higher than the world’s growth level in the same period, and the country is the fourth largest connector market leading the global rapid growth. China’s connectors are mainly low-end, high-end connectors accounted for a relatively low, but the demand growth is fast.     Facing the market and technological changes of connectors, enterprises should keep track of cutting-edge connector technologies, learn new connector technologies, gradually get rid of the competition of low-end products and develop high-end product lines.
