Crimping Tension Value: The Core Evidence Of The Quality Of Terminal Blocks

In the field of electrical connections, the quality of terminal blocks is directly related to circuit safety and operational stability, and the tension value after crimping is the most intuitive and core proof to measure its quality. The so-called crimping tension value refers to the maximum withstand force that a terminal can withstand against external pulling after crimping with a wire. It not only reflects the accuracy of the crimping process, but also directly determines the reliability and durability of the connection.

High quality wiring terminals need to have stable conductive connections and resistance to external forces, and the tension value can fully confirm these two points. If the crimping process is standardized and the terminal material is excellent, the crimping surface between the metal conductor and the terminal will form a tight metal bond, and the tensile value will naturally meet the standard; On the contrary, if there are too many impurities in the terminal material, insufficient crimping depth, or deformation of the crimping surface, it will lead to low tension values, which can easily cause safety hazards such as poor contact, heating, and even detachment during use. Especially in scenarios with severe vibrations such as automobiles and aerospace, sufficient tensile strength is the key defense line to avoid connection failure.

Tensile testing has become the core quality inspection standard in the terminal industry. Legitimate manufacturers will use professional equipment to sample and test each batch of products to ensure that the tensile strength values comply with national or industry standards. For users, paying attention to the tension value indicator is the first hurdle in controlling the safety of the connection. Whether in the fields of industrial control, smart home, or new energy, only wiring terminals that meet the required tensile strength can ensure long-term stable operation of circuits, reduce maintenance costs, and mitigate safety risks. Therefore, the tension value after crimping is the most direct and reliable touchstone for testing the quality of terminal blocks.
