XCE series-Circular Electrical Connector Manufacturers

How to control the quality of XCE series circular electrical connectors during production? Is a combination of online inspection and final inspection adopted?
1. Quality control preparation before production
Before the production process of XCE series circular electrical connectors was started, HENGLIAN had implemented a strict preliminary preparation and material screening mechanism. All raw materials, including high-strength aluminum alloy housings, thermosetting insulators, silicone rubber seals, and copper alloy contacts, must pass the strict review of suppliers and the company's secondary inspection to ensure that they meet the enterprise standard Q/321202HL003-2009 and relevant military and national standards. The company's technical center will also conduct performance tests on raw materials, such as mechanical strength, corrosion resistance, insulation resistance, etc., to ensure that each batch of materials can meet the high standards of product design.
2. Online inspection: real-time monitoring and instant adjustment
On the production line, HENGLIAN uses an advanced online inspection system to achieve real-time monitoring and instant adjustment of the production process. This system covers the entire process from raw material processing, component assembly to finished product initial inspection, ensuring that every step of the operation is accurate and correct.
Raw material processing monitoring: In the key processes such as cutting, drilling, and plating of aluminum alloy shells, high-precision sensors and machine vision technology are used to monitor the processing accuracy and plating quality in real time. Once deviations are found, equipment parameters are adjusted immediately to avoid the production of defective products.
Component assembly precision control: In the assembly process of contacts and insulators, automated assembly lines and precision measuring instruments are used to ensure that the insertion depth, position accuracy, and matching clearance between the jack and the pin of each contact meet the design requirements. The vibration test bench simulates the vibration conditions in the transportation and working environment to verify the stability of the assembly.
Preliminary inspection: After the initial assembly is completed, each product will undergo preliminary electrical performance tests, including contact resistance, insulation resistance, and withstand voltage tests to ensure that the electrical performance meets the standards. Automated testing equipment is used in this stage to greatly improve the efficiency and accuracy of inspection.
3. Final inspection: comprehensive verification and strict screening
The semi-finished products that have passed the online inspection will enter the final inspection stage, which is more comprehensive and strict, aiming to ensure that every XCE series circular electrical connector shipped from the factory can meet the highest standards.
Mechanical performance verification: The mechanical strength and durability of the connector housing, insulator and contact parts are verified by simulating vibration, impact and constant acceleration tests in actual use. The test basis strictly follows the requirements of enterprise standards and military standards to ensure that the connector can maintain a stable connection under extreme conditions.
Comprehensive electrical performance test: In the final inspection, each product will undergo a comprehensive electrical performance test, including but not limited to continuous current load, plug-in life test, high-frequency signal transmission characteristics, etc., to ensure that the electrical performance of the connector is stable and reliable in long-term use.
Appearance and dimension inspection: Using high-precision measuring tools and visual inspection systems, the appearance, size and key configuration of the connector are checked one by one to ensure that they are completely consistent with the design drawings and avoid the risk of blind insertion and misinsertion.
Environmental and reliability testing: Some products also need to undergo reliability tests in special environments, such as high temperature and humidity, salt spray corrosion, etc., to verify their adaptability and stability under harsh conditions.
IV. Support of the quality management system
HENGLIAN's quality control system not only relies on advanced testing technology and equipment, but also benefits from its perfect quality management system. As a qualified supplier of military electronic components in the fields of the Communications Department of the General Staff and the Ministry of Information Industry, the company has passed the GJB9001C-2017 weapons and equipment quality management system certification and the second-level secret certification for weapons and equipment production and scientific research units, ensuring that every link from product design, raw material procurement, production and manufacturing to finished product delivery meets the strict standards of the state and the military.
