On April 15th, National Security Education Day arrived as scheduled, which is an important day to remind us to always pay attention to national security and enhance our awareness of security prevention. Connectors, as a key bridge between information technology and physical devices, play a crucial role in ensuring national information security and physical security. So, how is the security performance of Jointlean connectors guaranteed?

一、Structural design: Enhance the stability and reliability of electrical connections

R&D design has a decisive impact on the safety performance of connectors. Zhiheng has many years of experience in R&D and manufacturing, and insists on making "designing a reasonable structure" a key goal in new product development, such as optimizing contact points, increasing fixing devices, and reserving sufficient safe electrical distance, to ensure a tight connection between connectors and systems, and to improve the stability and safety of connectors.

二、 Preferred materials and process control: an important link in ensuring the safety performance of connectors

1. Jointlean connectors meet the UL94-V0 flame retardant rating, which can to some extent prevent the spread of flames and reduce the risk of fire when exposed to external sources of fire. Achieving this requirement requires strict selection of plastic raw materials. Zhiheng selects internationally famous brands and high-quality imported raw materials. The high-quality raw materials have more stable physical and chemical properties, which can improve the heat resistance, cold resistance, aging resistance and flame retardancy of connectors.

2. As an important component of connectors, the quality and performance of metal parts have a significant impact on the safety performance of connectors. In the selection of metal parts, Zhiheng always insists on using high-quality copper alloys, which not only provide good conductivity, fatigue resistance, strength and toughness, but also maintain the structural integrity of copper alloy connectors in high temperature environments, without stress relaxation and creep, thus ensuring the stability and reliability of electrical connections.

3. Zhiheng adopts precision processing equipment and fine processing technology in the manufacturing process to control the processing accuracy and tolerance of connectors, improve the contact reliability of connectors, ensure that connectors meet design requirements in terms of electrical performance, mechanical performance, and environmental adaptability, and thus enhance the overall performance and safety of connectors.

三、 Performance testing: a key indicator of connector safety performance

1. Electrical performance: Electrical performance is a core consideration in the design and use of connectors, directly related to the functionality and safety of connectors. According to the national/industry standard testing requirements, Zhiheng conducts tests on electrical performance including contact resistance, insulation resistance, withstand voltage, impulse current, temperature rise, resistance to electric traces, surge, etc., and requires that the test results meet the more stringent enterprise standard requirements in order to evaluate the electrical performance of the connector and pass the inspection.

2. Mechanical performance: Mechanical performance is an important component of connector safety performance, determining the reliability and durability of connectors in complex environments. According to the national/industry standard testing requirements, Zhiheng conducts tests on mechanical properties including insertion and extraction force, vibration resistance, pendulum impact, wire pull-out, and coating film thickness detection. The test results must meet the more stringent enterprise standard requirements in order to evaluate the mechanical performance of the connector and pass the inspection.

3. Environmental performance: Good environmental adaptability is an important factor in ensuring the safety of connectors, which can ensure that connectors can work stably and reliably in specific environments. According to the national/industry standard testing requirements, Zhiheng conducts environmental performance tests on connectors, including salt spray, high and low temperature, alternating humidity and heat, welding heat resistance, flame retardancy, etc., and requires them to meet more stringent enterprise standard requirements in order to evaluate the environmental performance of connectors.

四、 Quality system certification and IP20 protection level: an important defense line for safeguarding electrical safety

Since its establishment, Zhiheng Electric has always adhered to a high pursuit of quality, built a quality control system that strives for excellence, and won multiple authoritative quality system certifications at home and abroad. Its main products have passed UL, TUV, CE, CQC and other domestic and international certifications, meeting the RoHS directive (environmental protection), and some products have been tested by the Cape Testing Center.

2. The entire range of Jointlean connectors complies with the IP20 protection level, which is the basic protection requirement for connectors. It ensures that the connector can effectively prevent solid foreign objects larger than 12.5mm from entering the interior of the connector and the harm caused by finger accidental contact under normal working conditions, avoiding possible electrical faults or short circuits. This protection level provides a basic guarantee for the stable operation of connectors in electrical systems.

The safety performance of connectors involves multiple aspects. In practical applications, we conduct comprehensive and detailed testing and evaluation from multiple perspectives such as design structure, material selection, manufacturing process, and experimental testing, continuously optimizing and improving to ensure the stability and reliability of Jointlean connectors in practical applications. We also pay attention to cutting-edge technological innovation and application, committed to improving the excellent quality and safety performance of Jointlean connectors, providing professional electrical connection solutions for Chinese enterprises to create world leading products, and contributing to the construction of a safe and stable social environment.
