2. The main electrical properties of electrical performance connectors include contact resistance, insulation resistance and anti -electricity strength.

① Electric connectors with high -quality contact resistance should have a low and stable contact resistance. The contact resistance of the connector ranges from several millions to dozens of dollars.

② Insulation resistance measured the indicator of the insulation performance between the contact parts and the contact of the contact part and the shell.

③ Anti -electricity strength or resistance voltage, media resistance, is the ability to characterize the rated test voltage between the contact parts between the connector contact or the shell and the shell.

④ Other electrical performance.

The attenuation of electromagnetic interference leakage is the electromagnetic interference shielding effect of the evaluation of the connector. The electromagnetic interference leak attenuation is the electromagnetic interference shielding effect of the evaluation of the connector. Generally, it is tested within the frequency range of 100MHz ~ 10GHz.

For radio frequency coaxial connector, there are electrical indicators such as characteristic impedance, insertion loss, reflex coefficient, and voltage bidding (VSWR). Due to the development of digital technology, in order to connect and transmit high -speed digital pulse signals, a new type of connector, namely high -speed signal connector, has appeared. In terms of electrical performance, in addition to characteristic impedance, some new electrical indicators also appeared. , Such as crosstalk, transmission delay (delay), SKEW, and so on.

3. Common environmental performance of environmental performance includes temperature resistance, humidity resistance, salt resistance, vibration and impact.

① The current operating temperature of the temperature-resistant connector is 200 ° C (except a few high-temperature special connectors), and the temperature is -65 ° C. Due to the connection device, the current generates heat at the contact point, resulting in temperature rise. Therefore, it is generally believed that the working temperature should be equal to the peaceful sum of the environmental temperature and the connection. In some specifications, the temperature rise that the connector is allowed to allow the connector at the rated working current.

② The invasion of wet moisture will affect the insulation performance of the connection H and rust metal parts. The constant humidity test conditions are relative humidity 90%~ 95%(according to product specifications, up to 98%), temperature+40 ± 20 ° C, the test time is according to product regulations, at least 96 hours. The intercourse damp and heat test is more stringent.

③ When the salt -resistant mog connector works in an environment containing a tide and salt, its metal structure parts and contact parts surface treatment layers may produce electrified corrosion, affecting the physical and electrical properties of the connector. In order to evaluate the ability of the electrical connector to tolerate this environment, salt fog tests are specified. It is to hang the connector in a test box where the temperature is controlled. The sodium chloride solution with a specified concentration is sprayed out with a compressed air to form a salt mist atmosphere. The exposure time is specified by the product specification, at least 48 hours.

④ Vibration and impact vibration resistance and impact are the important performance of electrical connectors. It is particularly important in special application environments such as aviation and aerospace, railway and highway transportation. Important indicators of sex. There are clear regulations in the relevant test methods. In the impact test, peak acceleration, duration and shock pulse wave shape, and electrical continuity interruption should be specified.

⑤ According to the requirements of the use of other environmental performance, other environmental performance of the electric connector also has sealing (air leakage, liquid pressure), liquid immersion (the ability to resist the ability to eliminate specific liquids), low air pressure, etc.
