In the event of a fault, it is not necessary to pinch off the cable, the plastic sleeve, etc., only need to unscrew the two ends of the waterproof connector, which is very convenient for product maintenance.
Basic performance of the connector
The basic performance of connectors can be divided into three categories: mechanical, electrical, and environmental. ,
1. Mechanical properties: In terms of connection function, the insertion and extraction force is an important mechanical property. The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different. There are maximum insertion force and minimum separation force regulations in the relevant standards, which indicates that the insertion force is small from the point of view of use (thereby having a low insertion force LIF and a structure without ZIF insertion), and if the separation force is too small, It will affect the reliability of the contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a measure of durability. It is judged by whether the connector can normally complete its connection function (such as contact resistance value) after one insertion and one extraction.
2. Electrical performance: The main electrical properties of the connector include contact resistance, insulation resistance and electrical strength.
1 Contact resistance High quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms.
2 Insulation resistance is a measure of the insulation properties between electrical connections and between the contacts and the enclosure, in the order of hundreds of megaohms to several gigaohms.
3 Electric strength or withstand voltage, dielectric withstand voltage is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the casing.
4 Other electrical properties Electromagnetic interference Leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector. The electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, and is generally tested in the frequency range of 100MHz~10GHz.
For RF coaxial connectors, there are electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR). Due to the development of digital technology, in order to connect and transmit high-speed digital pulse-balance signals, a new type of connector, high-speed signal connector, has emerged. Accordingly, in terms of electrical performance, in addition to the characteristic impedance, some new electrical products have appeared. Indicators, such as crosstalk. Transmission delay (delay), skew (skew), etc.
Common environmental properties include temperature resistance, moisture resistance, salt spray resistance, vibration and balance.
1 Temperature resistance The current maximum operating temperature of the connector is 200 ° C (except for a few high temperature special connectors), the lowest temperature is -65 ° C. Since the current generates heat at the contact point when the connector is in operation, resulting in a temperature rise, it is generally considered that the operating temperature should be equal to the sum of the ambient temperature and the junction temperature rise. In some specifications, the maximum temperature rise allowed by the connector at rated operating current is specified.
2 Intrusion of moisture and moisture can affect the insulation performance of the connector and etch metal parts. Constant damp heat test conditions are relative humidity of 90% to 95% (according to product specifications, up to 98%), temperature +40 ± 20 ° C, test time according to product regulations, at least 96 hours. The alternating heat and humidity test is more stringent.
3 When the salt spray resistant connector is operated in an environment containing moisture and salt, the metal structural parts and the contact surface treatment layer may cause galvanic corrosion and affect the physical and electrical properties of the connector. In order to evaluate the ability of electrical connectors to withstand this environment, a salt spray test is specified. It suspends the connector in a temperature-controlled test chamber and sprays it with compressed air at a specified concentration of sodium chloride solution to form a salt spray atmosphere. The exposure time is specified by the product specification for at least 48 hours.
4 Vibration and Weighing Vibration and balance are important properties of electrical connectors. They are especially important in special applications such as aerospace and aerospace, railway and road transportation. They are to verify the robustness and electricality of the mechanical structure of electrical connectors. An important indicator of contact reliability. There are clear regulations in the relevant test methods. Peak acceleration, duration, and balance pulse-balance waveforms, as well as the time of electrical continuity interruption, should be specified in the balance test.
Other environmental performance According to the use requirements, other environmental properties of the electrical connector are also sealed (air leakage, liquid pressure), liquid impregnation (resistance to specific liquids), low air pressure, and the like.
