The three basic performance characteristics of the connector, read it and remember to bookmark it!

Electronic connectors are also known as circuit connectors, electrical connectors, as the name suggests, is to bridge the two conductors of a circuit, so that the current or signal can flow from one conductor to another conductor conductor equipment. Electronic connector belongs to a kind of motor system, it can provide a separable interface to make the connection between the two sub-electronic systems, in simple terms, that is, with the completed circuit or electronic machine and so on, the electrical connection between the components are called connector that is, the bridge between the two. The following are the three basic properties of the connector:

1, mechanical properties: for the connection function, insertion and extraction force is an important mechanical properties. Insertion and extraction force is insertion and extraction force (also known as pull-out force), the requirements between the two are different. In the relevant standards, there is a maximum insertion force and minimum separation force provisions, which indicates that, from the point of view of the use of the insertion force should be small, not separated if too small, the side will affect the reliability of the contact. 2, electrical properties: the main electrical properties of the connector, including the contact resistance, insulation resistance and resistance to electric strength. (1) contact resistance: high-quality electrical connectors have a bottom and stable contact resistance. However, the contact resistance of the connector is from a few ho ohms to several ho ohms. (2) Insulation resistance: we measure the electrical connector contact between the contact parts and the contact parts and the shell between the insulation performance indicators, the number of extremely hundreds of megohms to thousands of megohms ranging. (3) Resistance to electric strength or voltage, dielectric withstand voltage, is to indicate that the connector between the contact parts or between the contact parts and the shell to withstand the rated test voltage. (4) other electrical properties: electromagnetic interference leakage attenuation is to evaluate the connector's electromagnetic interference shielding effect, generally lies in the range of 100MHz-10GHz frequency test. 3, environmental performance: common environmental properties include: temperature resistance, salt spray resistance, resistance to moisture vibration and shock and so on. (1) temperature: the current maximum operating temperature of the connector 200 degrees Celsius (except for a few high-temperature special connectors), the lowest temperature is -65 degrees Celsius. As the connector works, the current in the contact point of heat generated at the point of contact and lead to temperature rise, so the general view is that the operating temperature is equal to the ambient temperature and pick up the temperature rise and. In some specifications, the connector is clearly identified in the rated operating current under the maximum allowable temperature rise. (2) temperature moisture intrusion will also affect the connector insulation, and will corrode metal parts. Constant wet test conditions for the relative temperature of 90% -95%, the test time according to the product, at least 96 hours, change the side of the hot and humid test will be more stringent. (3) salt spray: connectors in the environment containing moisture and salt work is one of the metal structural components, contact parts surface treatment layer may produce galvanic corrosion, but also affects the physical and electrical properties of the connector. So in order to evaluate the electrical connector to withstand the ability of this Hua Ning, deliberately specified salt spray test. (4) vibration and shock: vibration and shock resistance is an important performance of the electrical connector, is in special applications such as: aviation and aerospace, rail and road transportation is more important, it is to test the mechanical structure of the electrical connector and the robustness of the electrical contact reliability of the important indicators. (5) other environmental performance: according to the use of requirements, the connector's other environmental performance and sealing (air leakage, liquid pressure), liquid impregnation (on the specific liquid resistance to abusive chemical ability) and low air pressure and so on.
