Jousiliittimet

Jousiliittimet, often referred to as spring connectors or wire connectors, are mechanical devices designed to securely join two or more electrical wires. They are a common alternative to traditional wire nuts, particularly in certain electrical installations. The primary mechanism of a jousiliitin involves a metal spring or cage that grips the stripped ends of wires when they are inserted. This spring action creates a constant tension, maintaining electrical contact and preventing the wires from becoming loose.

These connectors typically consist of a plastic housing that encloses the spring mechanism. The housing is often color-coded to indicate the maximum wire gauge or the number of wires the connector is designed to accommodate. The insertion of wires is usually straightforward, requiring a simple push or twist motion. Some types may have ports for testing voltage without disconnecting the wires.

Jousiliittimet are valued for their ease of use and speed of installation, which can reduce labor time. They also offer a compact and sometimes more aesthetically pleasing connection compared to bulky wire nuts. Common applications include residential wiring, such as connecting light fixtures, switches, and outlets, as well as in appliance manufacturing and other areas where quick and reliable wire termination is needed. Safety standards and electrical codes often specify the types of connectors permitted for different applications.
