Many customers in the selection of electronic connector manufacturers, many only consider its price, but product quality, safety and reliability is the priority. So how do you understand the reliability factor of an electronic connector?
First, the reliability of the electronic connector can be based on these several factors:
1. Materials for product design and production
2. Operating environment
3, the functional requirements of the application of the environment, especially temperature, humidity, corrosion, determine what their failure mechanism will occur, and the connector functional requirements, determine what degree of failure is allowed.
Two, the connector reliability evaluation program includes these contents:
1. Determine acceptable standards for application, including terminal resistance and other failure modes. Identify and classify the failure mechanisms that occur according to the importance of the application.
2. Develop test procedures to deal with the failure mechanism in the application of prediction, ranking and grading.
3. Determine the acceleration factor and do special tests if possible.
4. Make appropriate data analysis and statistical processing according to the data obtained from the appraisal procedure.
5. Evaluating reliability The above steps depend on engineering judgment. The manufacturer and user of the connector shall agree on the content and methods of the qualification procedure.
Three. Connectors are defined in terms of function and structure:
Electronic connectors provide a detachable connection between two subsystems in an electronic system without unacceptable impact on system performance.
2. Separability is the reason why we want to use connectors to facilitate the maintenance and upgrading of subsystems or parts of a system. At the same time, this connection cannot have any unacceptable impact on the performance of the system. Such as signal absorption, attenuation, power loss. The requirements for detachable and unacceptable limits depend on the specific application requirements of the connector.
3, structurally defined, the connector has four structural elements, they are: A, terminal (between) contact interface B, terminal surface treatment C, terminal reed D, connector housing.
