jakkoliitännät

Jakkoliitännät, commonly known as jack connectors or phone connectors, are a type of electrical connector used for both analog and digital signals. They are widely employed in audio and telecommunications applications. The most common types are 6.35 mm (1/4-inch) and 3.5 mm (1/8-inch) diameter jacks.

These connectors typically consist of a plug and a socket. The plug has a cylindrical shaft divided into sections by insulating rings. These sections correspond to different signal paths. The most basic jack has two sections: a tip and a sleeve (TS), used for mono audio signals. A three-section plug, with a tip, ring, and sleeve (TRS), can carry stereo audio or balanced mono signals. Four-section plugs (TRRS) are used for applications like headsets with microphones or video signals.

The smaller 3.5 mm jack is prevalent in consumer electronics, such as headphones for smartphones, laptops, and portable music players. The larger 6.35 mm jack is a standard in the professional audio industry, found on musical instruments, amplifiers, and studio equipment. Jakkoliitännät are designed for easy and quick connection and disconnection. They are generally robust and capable of handling moderate current and voltage levels, although their primary use is signal transmission.
