What are the connections of cold-pressed terminals?
The connection of cold crimping terminals includes screw connection: Although screw connection also uses screw terminal connection, the connection method of this cold crimping terminal actually needs to pay attention to the allowable connection line. Screws of different specifications and the maximum and minimum cross-sectional areas allow greater tightening torque.
The connection of the cold-pressed terminal involves welding. If the incoming material is welded, it should be noted that gas death is more common, but there are also welded ones. The more important thing in the solder connection is the continuity of the metal between the solder and the surface to be soldered. This is why, for cold-pressed terminals on wire terminals, solderability is actually more important.
The more common plating on the soldering end of the terminal ring is tin alloy, silver or gold. Lead contacts actually include welding head type and punch type, notch type and pinhole type contacts, and there are also circles drilled from the arc gap type.
The connection method of the cold-pressed terminal also includes crimping. In the case of crimping, in most cases, the metal is actually compressed and moved within the specified range, and the wires are also directly connected. Contact right. In practical applications, we will find that a good crimping method will produce metal intermetallic flow, resulting in symmetrical deformation of the wire and contact with the material.
The connection of the cold-pressed terminal is actually more similar to the cold-welded connection, which can directly achieve better mechanical strength and electrical continuity, so be careful to withstand the harsher environment. Conditions within a certain range. For current cold crimping terminal connections, it is generally believed that correct crimping is better than soldering.
