    Connector performance analysis
        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...

    Standard definition and foundation of connectors
        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...

    What is the effect connector terminals?
        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!
