The basic properties of connectors can be categorized into several types?

The basic properties of connectors can be categorized into three main groups: namely, mechanical properties, electrical properties and environmental properties. Another important mechanical properties is the mechanical life of the connector. Mechanical life is actually a durability (durability) indicators. It is an engagement, separation for a cycle, in order to specify the engagement, separation cycle after the connector can normally complete its connection function (such as contact resistance value) as the basis for judgment.

First, the mechanical properties of the connection function, insertion and extraction force is an important mechanical properties of insertion and extraction force is divided into the insertion force and pull-out force (pull-out force is also known as separation force), the two requirements are different. In the relevant standards have a greater insertion force and minimum separation force provisions, which indicates that, from the point of view of the use, the insertion force should be small (thus having a low insertion force LIF and no insertion force ZIF structure), while the separation force is too small, it will affect the reliability of the contact. The insertion and extraction force and the mechanical life of the connector are related to the structure of the contacts (magnitude of the positive pressure) the quality of the plating on the contact area (coefficient of sliding friction) as well as the dimensional accuracy of the arrangement of the contacts (degree of alignment).

Second, the electrical properties of the connector's main electrical properties, including contact resistance, insulation resistance and electrical strength. 1. contact resistance of high-quality electrical connectors should have a low and stable contact resistance. 2. insulation resistance measures the insulation between the electrical connector contacts and between the contacts and the shell. Connector contact resistance from a few milliohms to tens of milliohms. 2. insulation resistance measure of electrical connectors between the contact and contact and shell insulation performance indicators, the order of magnitude of hundreds of megohms to thousands of megohms ranging. 3. resistance or voltage, dielectric withstand voltage, is to characterize the connector between the contact or between the contact and the shell to withstand the ability to withstand the rated test voltage. 4. other electrical properties.

Third, the environmental performance of common environmental performance, including temperature resistance, moisture resistance, salt spray resistance, etc. 1. Temperature resistance of the current connector higher operating temperature of 200 ℃ (except for a few high-temperature special connectors), and lower temperatures for -65 ℃. As the connector works, the current at the point of contact to generate heat, resulting in temperature rise, so it is generally believed that the operating temperature should be equal to the ambient temperature and the temperature rise of the contact point and the sum. In some specifications, it is specified that the connector in the rated operating current under the allowable higher temperature rise. 2. Resistant to moisture moisture intrusion will affect the connection h insulation properties, and corrosion of metal parts. Constant humidity and heat test conditions for the relative humidity of 90% to 95% (according to product specifications, up to 98%), temperature +40 ± 20 ℃, the test time according to product regulations, at least 96 hours. Alternating humidity and heat test is more stringent. 3. Salt spray connectors in the environment containing moisture and salt work, its metal structural components, contact parts of the surface treatment layer may produce galvanic corrosion, affecting the connector's physical and electrical properties. In order to evaluate the ability of electrical connectors to withstand this environment, the salt spray test is provided.-4、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products}; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable products we can provide solutions, please contact the following Division Division I business personnel!
