XCD series-Circular Electrical Connector Manufacturers

XCD series-circular electrical connectors provide a variety of tail termination forms. How are these termination forms designed and manufactured? What are the special process requirements?
In order to meet the needs of different application scenarios, XCD series-circular electrical connectors are designed with a variety of tail termination forms, including but not limited to crimping, welding, threading, and PCB board mounting. These termination forms are designed to ensure a stable connection between the electrical connector and the cable or circuit board, while improving the reliability and durability of the connection.
Crimping termination: The conductor of the cable is tightly pressed with the crimping terminal of the connector through a special crimping tool to form a reliable electrical connection. Crimping termination has the advantages of simple operation, firm connection, and easy maintenance. It is widely used in connections that require frequent plugging and unplugging or vibration environments.
Welding termination: The conductor of the cable is directly welded to the welding terminal of the connector, and the high temperature of welding causes the two to melt and combine to form a dual connection in electrical and mechanical aspects. Welding termination is suitable for occasions with extremely high connection strength requirements or limited space.
Threaded termination: The conductor of the cable is tightly locked with the terminal of the connector through a threaded structure to achieve electrical connection. Threaded terminations are anti-loosening, vibration-resistant, and suitable for high current transmission. They are often used for electrical connections outdoors or in harsh environments.
PCB board mounted terminations: The connector is directly mounted on the PCB board through SMT (surface mount technology) or THT (through-hole mounting technology) to achieve electrical connection with the circuit board. This termination form is suitable for high-density, high-integration circuit board designs.
During the manufacturing process, the tail termination form of the XCD series-circular electrical connector follows a series of strict quality control processes and special process requirements to ensure the quality and performance of the product.
Material selection and processing: The materials of the connector terminals, shells, and insulators are all made of high-performance, corrosion-resistant, and high-temperature resistant high-quality materials. For example, the terminals are made of copper alloy gold-plated to improve conductivity and corrosion resistance; the shell is made of high-strength aluminum alloy or stainless steel to enhance mechanical strength and environmental resistance; the insulator is made of thermosetting materials to ensure electrical insulation performance in harsh environments such as high temperature and high humidity.
Precision machining and assembly: The terminals are processed by high-precision CNC machine tools to ensure that the dimensional accuracy and shape tolerance of the terminals meet the design requirements. During the assembly process, automated assembly lines and special fixtures are used to ensure accurate matching and stable connection between the components.
Special process treatment:
Plating treatment: Gold plating is performed on the surface of the terminals to improve conductivity and corrosion resistance. The thickness and uniformity of the plating must be strictly tested to ensure that it meets the design requirements.
Anti-loosening treatment: For threaded terminations, a special anti-loosening structure or anti-loosening agent is used to prevent loosening caused by vibration or external force during use.
Welding quality control: The welding process of the welding termination requires strict control of parameters such as welding temperature, welding time and welding pressure to ensure welding quality and connection strength. Welding quality inspection and reliability testing are required after welding to verify its electrical and mechanical properties.
Nondestructive testing and high-precision geometric shape testing: During the manufacturing process, advanced testing equipment such as spectrometers, metallographic microscopes, universal tensile testing machines, low-temperature impact testing machines, salt spray testers, insulation resistance testers, and voltage testers are used to perform nondestructive testing and high-precision geometric shape testing on connectors. These testing methods can ensure that there are no defects or damage to the connectors during the manufacturing process, while ensuring that their geometric shape and dimensional accuracy meet the design requirements.
Quality certification and system guarantee: Henglian has passed a number of military qualifications such as the GJB9001C-2017 National Military Standard Quality Management System Certification, and has obtained ISO 9001, ISO/TS16949 and other quality management system certifications. These certifications not only prove the company's outstanding performance in quality management, but also provide customers with trust and guarantee of product quality.
