What is a cold-pressed terminal?

Insulated terminals, also known as cold-pressed terminals, electronic connectors, and in-line splices, all fall under the category of cold-pressed terminals. They are accessory products used for achieving electrical connections and are classified within the realm of connectors in industry. With the increasing degree of industrial automation and the ever-stricter and more precise requirements for industrial control, the usage of wiring terminals has gradually risen. Along with the development of the electronics industry, the application scope of wiring terminals has expanded, and so has the variety of types available.

Definitions and Nomenclature of Cold-Pressed Terminals:

Round pre-insulated terminals, cold-pressed wiring terminals, power fittings, fork-shaped pre-insulated terminals, pin-shaped pre-insulated terminals, blade-shaped pre-insulated terminals, bullet-shaped fully insulated terminals, long intermediate splices, short intermediate splices, round bare lugs, fork-shaped bare lugs, male and female pre-insulated terminals, tubular pre-insulated terminals, tubular bare lugs, pin-shaped bare lugs,窥口系列SC (peep-hole series SC), DTG copper wiring terminals, and C45 dedicated terminals.

In the field of electronic technology, the most effective use of cold-pressed terminals involves handling track-type copper conductors at different terminal wiring positions. Initially, insulating sleeves were not used, but since the 1970s, their application has become widespread. In 1991, the invention of double-splice cold-pressed terminals with the same wire diameter sparked a revolution in the cold-pressed terminal market.

The issuance of the DIN 46228 standard in 1990 marked another milestone in the history of cold-pressed terminals. This standard primarily focuses on the unified color coding of insulating sleeve rings.
