Analysis of domestic connector quality accidents: Taking Smiths Interconnect as an example

In the application of high-reliability connectors, quality accidents not only affect system performance but may also lead to significant economic losses and reputation crises. This article will combine the product characteristics of Smiths Interconnect to analyze typical quality management issues of domestic connectors and put forward corresponding improvement suggestions.

One, quality control advantages of Smiths Interconnect
Smiths Interconnect is a leading global supplier of high-reliability connectors, with products widely used in aerospace, defense, medical fields and more. Its quality control system includes:
● Hypertac® supercoiling contact technology: providing excellent electrical performance and mechanical stability, suitable for high vibration and impact environments.
● Strict production process: Using high-precision manufacturing equipment and technology to ensure product consistency and reliability.

●Comprehensive test verification: Conduct environmental tests such as high temperature, high humidity, vibration, and impact on the product to ensure its stability under harsh conditions.

Second, case analysis of domestic connector quality accidents
Although domestic connectors have an advantage in cost, there are still some issues in quality control, which have led to multiple quality accidents:
Contact corrosion leads to signal interruption
In some domestic connectors, low-cost contact materials are used, which lead to corrosion of the contact points during use, increase contact resistance, and ultimately cause signal transmission interruption.
Insufficient insertion and extraction times lead to poor contact.
The design of some domestic connectors does not fully consider the requirements of insertion and extraction times, leading to a decrease in contact performance under frequent insertion and extraction, and the occurrence of poor contact.
Poor sealing performance leads to poor environmental adaptability.

Some domestic connectors have defects in their sealing design, which leads to internal components becoming damp or oxidized in harsh environments such as humidity and high temperature, affecting the normal operation of the connector.

Lesson and Improvement Suggestions
Through the above case analysis, the following lessons can be drawn:
Material selection should be cautious: materials with good conductivity and corrosion resistance should be chosen to ensure the long-term stability of the connector.
The design must meet the actual application requirements: when designing, the usage environment and frequent insertion and removal of the connector should be fully considered to ensure that its performance meets the actual application requirements.
Strengthen quality control: Strict control should be exercised over each link in the production process to ensure the consistency and reliability of the product.

Comprehensive test verification should be conducted: Before the product is put into use, it should undergo high temperature, high humidity, vibration, impact, and other environmental tests to ensure its stability under harsh conditions.

Domestic connectors have an advantage in cost, but they still need to strengthen quality control. By learning from Smiths Interconnect's quality control experience, the quality level of domestic connectors can be improved to better meet the needs of high-reliability applications.
