  • Necessary connectors
    Necessary connectors May 07, 2018
        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.

    Connector performance analysis Apr 02, 2018
        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.
