The Chain Reaction Triggered By The Shrinking Size Of Copper Terminal Blocks In The Market

After continuous tracking of the copper terminal block market, it was found that the thickness and width of some supply chains frequently deviate from the standard. Such dimensional shrinkage is often difficult to detect visually during the factory inspection process, but it has a related impact on the overall assembly gap and electrical contact status. Industry standards specify basic ranges for width and thickness; specific dimensions should be set according to application and current-carrying requirements. Excessive thinning or narrowing alters the original physical current-carrying path and thermal management conditions.

During the production process, the machining accuracy of copper distribution block is directly related to the fit of subsequent equipment assembly. Many manufacturers have strict internal regulations for dimensional control during procurement, manufacturing, and processing. However, some small-batch or cost-oriented suppliers often reduce the amount of copper used in actual production, leading to deviations in batch product dimensions from the set standards. External inspection revealed that the cross-sectional dimensions of the copper terminal strip that were not manufactured according to the design specifications were often smaller than those required by the contract. This change in physical parameters would positively affect the current distribution and mechanical connection fit.
