Push-In Connecting Terminal

-- Steady & Reliable Manufacturer --

Connecting Terminal Overview

A connecting terminal is a general-purpose electrical junction component that provides a safe, accessible, and re-connectable point for joining two or more conductors without soldering. Connecting terminals are the foundation of modern wiring practice — found in every control panel, distribution board, and equipment enclosure where wires must be terminated cleanly, identified individually, and serviced without cutting or rewiring the circuit.

Fenglan's connecting terminal range covers screw-clamp, spring-clamp, and push-in variants in ratings from 10 A to 125 A, for wire sizes 0.5 mm² to 95 mm², suitable for DIN 35 rail, panel, and PCB mounting. All current-carrying parts are tin-plated electrolytic copper housed in UL94 V-0 polyamide, and the full range is CE and RoHS compliant.

Application

Connecting terminals serve as the wiring backbone across virtually every electrical and electronic system:

  • Industrial control panels and PLC cabinets — terminating field-device wiring, power supplies, and I/O signals in a single organised wiring zone
  • Power distribution boards — distributing mains and sub-circuit feeds to downstream loads via a common terminal strip
  • Machine tool and automation systems — connecting sensors, actuators, servo drives, and safety relays in structured wiring compartments
  • Building and facility management systems — HVAC controllers, lighting panels, access control, and fire alarm field wiring junction points
  • Renewable energy systems — solar inverter, wind turbine controller, and battery management system wiring
  • Railway and transportation panels — vibration-rated connections for cab control, door systems, and traction equipment wiring
  • Marine and offshore enclosures — navigation, propulsion control, and alarm system wiring requiring corrosion-resistant terminals

Advantage

  • Three connection technologies in one range — screw clamp for permanent high-current circuits, spring clamp for rapid tool-free wiring, and lever-lock for reusable connections; all use the same housing footprint and accessory ecosystem
  • Modular and infinitely expandable — individual blocks snap together to form strips of any length and can be extended, regrouped, or relocated at any time without rewiring adjacent positions
  • Colour-coded for circuit identification — grey for general signals, blue for neutral, green/yellow for protective earth, and orange for hazardous live circuits, in line with IEC 60446 colour conventions
  • Full accessory ecosystem — end brackets, separators, shorting bridges, marker strips, test plugs, and end covers from the same product family simplify panel design and reduce sourcing complexity
  • 1,000 V rated for broad applicability — the 1,000 V AC/DC rating covers low-voltage power, control, and instrumentation circuits within a single product family, eliminating the need for separate high-voltage terminal types in most applications
  • CE and UL dual certification — third-party listed for both European and North American markets, allowing OEMs to use the same terminal in equipment shipped worldwide without product variants

A commercial invoice, packing list, and COA are provided with every shipment. For large OEM orders, customized packaging and private-label options are available upon request.

  • Q: What is the difference between a screw-clamp and a spring-clamp connecting terminal?
  • A: A screw-clamp terminal uses a captive screw to drive a pressure plate against the conductor. It requires a screwdriver to connect and disconnect, accepts the widest range of wire sizes including solid and stranded without ferrules, and allows the clamp force to be verified with a torque tool — making it preferred for permanent, high-current, or safety-critical circuits. A spring-clamp terminal uses a stainless-steel spring that clamps the wire automatically on insertion and releases with a push-button or screwdriver push-pin — it is significantly faster to wire and maintains constant contact pressure without periodic re-tightening, making it ideal for high-volume panel assembly and smaller signal wires.
  • Q: Do I need to use wire ferrules with connecting terminals?
  • A: Ferrules are strongly recommended for all stranded wire regardless of terminal type. They consolidate all strands into a single solid pin, prevent individual strand breakage under repeated screw tightening, and make re-termination clean and repeatable. Spring-clamp push-in terminals specifically designed for solid wire or ferrule-only insertion require ferrules; screw-clamp saddle-type terminals can accept un-ferrulated stranded wire, though ferrules still improve contact quality.
  • Q: How many wires can I connect to one terminal position?
  • A: Standard single-level terminals accept one wire per side (two wires total — one in, one out). For applications requiring multiple wires at one position, use a twin-entry terminal (two wire entries per clamping point) or a multi-level terminal block with two or three independent clamping levels in the same footprint. Alternatively, use a shorting bridge to electrically link adjacent single-level terminals, distributing the same potential to multiple output wires.
  • Q: Can connecting terminals be used for both AC and DC circuits in the same panel?
  • A: Yes, provided the voltage and current ratings are not exceeded. Our terminals rated to 1,000 V AC/DC are suitable for both AC power and DC control circuits. For safety and troubleshooting clarity, separate AC power terminals from DC signal terminals using colour-differentiated blocks or physical separators, and use dedicated green/yellow terminals for all protective earth connections.
