XCM series-Circular Electrical Connector Manufacturers

What specific measures have been taken by the XCM series-circular electrical connector to achieve moisture-proof, salt spray-proof, mildew-proof and rain-proof properties? In which production link are these treatment measures carried out? How to ensure the treatment effect?
1. Specific content of moisture-proof, salt spray-proof, mildew-proof and rain-proof measures
Material selection and surface treatment
High-strength high-quality aluminum alloy shell: The XCM series circular electrical connector uses high-strength high-quality aluminum alloy as the shell material. This material itself has good corrosion resistance and can effectively resist salt spray erosion. In addition, the aluminum alloy shell is precisely processed and anodized to form a dense oxide film, which further enhances the ability to prevent moisture and salt spray.
Wire spring jack design: The jack of the plug-in connector adopts a wire spring hole design. This structure is not only soft to plug and unplug and has low contact resistance, but also the elasticity of the wire spring can fit the pin tightly, effectively preventing the infiltration of water vapor and salt spray.
Contact welding and plating treatment: The contact is made of high-quality copper alloy material, and the connection is firm through precision welding technology. The contact surface is plated with precious metals (such as gold, silver or nickel-palladium alloy). These coatings can not only effectively prevent oxidation and corrosion, but also provide excellent electrical conductivity, further enhancing the ability to resist moisture and salt spray.
Sealing structure design
O-ring: O-rings are designed in key parts of the connector, such as between the shell and the socket, and between the plug and the socket. This design can effectively isolate the intrusion of external moisture, dust and salt spray, and ensure the dryness and cleanliness of the inside of the connector.
Potting technology: For some models with special requirements, HENGLIAN also uses potting technology, that is, filling the inside of the connector with moisture-proof and mildew-proof potting glue. This glue can not only effectively prevent the intrusion of water vapor and mildew, but also provide a certain buffering effect, enhancing the vibration and impact resistance of the connector.
Special coating treatment
Triple-proof coating: A layer of triple-proof coating (moisture-proof, salt spray-proof, and mildew-proof) is applied on the surface of the connector shell and some internal parts. This coating has good permeability and adhesion, and can form a dense protective film to effectively block the impact of the harsh external environment on the connector.
2. Implementation of treatment measures
The above treatment measures are mainly carried out in the following key links in the production process:
Material preparation and pretreatment: After the raw materials are purchased, strict inspection is first carried out to ensure that the materials meet the design requirements. Then necessary pretreatment is carried out, such as cleaning, degreasing, pickling, etc., to prepare for subsequent surface treatment and processing.
Processing and assembly: During the processing, the processing accuracy and surface roughness are strictly controlled to ensure the close fit of each component. During assembly, special attention is paid to the installation position and tightness of the O-ring, as well as the welding quality and plating uniformity of the contact parts.
Surface treatment and coating: After the processing and assembly are completed, the connector is surface treated, such as anodizing, plating, etc. Subsequently, the three-proof coating is applied as needed to ensure that the coating is uniform and without omissions.
Detection and testing: After each production link is completed, strict quality inspection and performance testing will be carried out, including simulation tests for moisture, salt spray, mildew and rain, to ensure that the connector meets the design requirements.
3. Methods to ensure the treatment effect
In order to ensure the effectiveness of the above treatment measures, HENGLIAN has taken the following measures:
Advanced production equipment and technology: The company has introduced advanced production equipment and production lines at home and abroad, and adopted automated and intelligent production processes to ensure precise control and stable quality of each production link.
Strict quality control system: The company has established a complete quality management system. From raw material procurement to finished product delivery, each link is strictly inspected and tested to ensure that product quality meets national and industry standards.
Technology research and development and innovation capabilities: The company has a technology center and a high-quality R&D team dedicated to the research and development of new products and technological innovation. Through continuous technological improvement and optimization, the performance and reliability of products are improved.
Customer feedback and continuous improvement: The company attaches great importance to customer feedback and regularly tracks product quality and conducts satisfaction surveys. According to customer feedback, timely adjust production processes and product designs to meet changing market needs.
