juhtplokid

Juhtplokid are electrical components used to connect and organize multiple electrical conductors within a device or installation. They serve as junction points that distribute electrical power or signals from a supply to several outgoing conductors, while providing mechanical support and electrical insulation.

A typical juhttplokk consists of a conductive core, most often copper or brass, forming a bus or terminal contact, housed in an insulating body. Terminals or clamps are provided for attaching wires, commonly by screws, spring clamps, or push-in connections. Juhtplokid can be single-row or multi-pole and may be designed for through-hole mounting on panels or for surface mounting. Materials for the insulating body include phenolic, nylon, or polycarbonate, chosen for electrical insulation, heat resistance, and mechanical durability.

Applications include electrical control cabinets, distribution boards, industrial equipment, and automotive or consumer electronics where reliable, multi-wire connections are needed. They are used to organize wiring, simplify disconnection and maintenance, and improve safety by keeping conductors securely in place and properly separated.

Key specifications cover current rating, voltage rating, insulation resistance, and temperature range, along with environmental and mounting requirements. Compliance with relevant standards and marking (for example CE in the European market) is common in modern products. Proper installation involves correct stripping length, torque on screws, secure labeling, and attention to insulation integrity. Regular inspection helps prevent loose connections or corrosion, which can compromise safety and performance.
