Why Are Our Terminal Blocks More Resistant To Plugging And Unplugging?
The resistance to plugging and unplugging of terminal blocks directly determines the stability and service life of electrical connections, especially in scenarios such as frequent maintenance and equipment debugging, where this characteristic is a core requirement. Our terminal blocks have better resistance to plugging and unplugging due to the comprehensive optimization of material selection, structural design, and process upgrades, which fundamentally solve pain points such as wear and poor contact during the plugging and unplugging process.
High quality core materials are the fundamental guarantee for resistance to plugging and unplugging. We choose high-purity copper as the conductor substrate. Copper not only has excellent conductivity, but also has excellent ductility and wear resistance, which can effectively reduce mechanical losses during insertion and extraction. At the same time, the contact area of the terminal is treated with gold or silver plating technology, with a uniform and dense coating and much higher hardness than ordinary copper materials. This can significantly reduce the friction coefficient during the insertion and removal process, avoid contact point wear and oxidation caused by repeated insertion and removal, and ensure stable contact performance even after long-term insertion and removal.
Scientific structural design further enhances the reliability of plug and play resistance. The terminal adopts a buckle type precise positioning structure, which has strong guidance during the insertion and removal process, avoiding additional damage caused by misalignment insertion and removal; At the same time, the contact pressure design has been optimized, and through the reasonable proportion of elastic elements, the terminal and wire are in close contact without increasing the insertion and removal resistance due to excessive pressure, reducing mechanical wear. In addition, the terminal housing is made of high-strength flame-retardant engineering plastic, which has good impact resistance and dimensional stability, and can provide reliable protection for the internal conductive structure, avoiding deformation of the housing during insertion and removal and affecting the connection accuracy.
Strict process control and testing verification ensure consistency in plug and unplug performance. We strictly control key indicators such as coating thickness and deformation accuracy of elastic components during the production process. Each batch of products must pass over 5000 insertion and extraction cycles, and the testing standards far exceed the industry's conventional requirements. After repeated verification in extreme environments, our terminal blocks can maintain stable electrical connections and mechanical performance even in high-frequency plugging and unplugging scenarios, with a service life that is more than 30% longer than ordinary terminals, providing solid guarantees for the safe and stable operation of various electrical equipment.
