Straightforward termination of solid and stranded wires spanning from 26 to 6 AWG

PCB spring clamp terminal blocks for vibration-heavy electronics

Xucheng spring terminal blocks with push-in clamping mechanisms are designed for vibration-prone industrial electronics. The tempered alloy spring applies continuous contact pressure against the conductor, compensating for wire relaxation and thermal expansion.

Push-in direct insertion technology speeding up panel wiring without handheld screwdrivers
Continuous spring clamping pressure maintaining contact during heavy shock and vibration
Convenient push-button actuator allowing quick wire extraction during test adjustments
Compact housing profile supporting dense component layout on multi-layer controller boards

Pluggable terminal block headers and mating plug connectors

Xucheng two-piece pluggable terminal blocks comprise PCB solder pin headers and detachable wire plug connectors. The configuration allows swift disconnection of electronic controller modules and field sensor harnesses without disassembling field wiring bundles.

Pitch dimensions of 3.81 mm, 5.0 mm, 5.08 mm, and 7.62 mm spanning 2 to 24 pole counts
Mechanical polarization keys preventing incorrect mating during field assembly operations
Optional screw flange locks delivering firm mechanical retention against pulling forces
Tin-plated and gold-flashed contact terminals preserving low interface contact resistance

XCDS series knife disconnect terminal blocks for control panels

Xucheng disconnect terminal blocks in XCDS-2.5 and XCDS-25 series feature hinged knife switches for safe circuit isolation. The mechanism enables technician inspection across measurement loops and secondary relays without detaching connected industrial wiring.

Hinged disconnect knife offering clear visual confirmation of open circuit electrical state
Integrated test sockets accommodating multimeter probe tips for uninterrupted circuit checks
XCDS-2.5 and XCDS-25 models built for standard instrument signal and control wiring sizes
Protection for current transformer secondary loops and sensor inputs during maintenance

Heavy-duty barrier terminal blocks with protective covers

Xucheng barrier terminal blocks are engineered for high-current power distribution inside electrical enclosures and motor control centers. Robust insulating barriers prevent inter-terminal bridging and electrical flashover when connecting heavy lug cables.

Rigid dielectric base molded with high insulating partitions between terminal poles
Transparent snap-on polycarbonate covers protecting personnel from accidental contact
Heavy screw terminals accommodating ring and spade wire lugs handling currents up to 100 A
Resilience against elevated ambient temperatures and airborne industrial contaminants

DIN rail modular connection architecture across TS 35 profiles

Xucheng XCDT series modular terminal blocks are engineered for compact installation within power distribution enclosures, relay protection cubicles, and process automation stations.

The components mount directly onto standard TS 35 top-hat metallic rails conforming to EN 60715 guidelines, maintaining secure retention under heavy mechanical vibration.

Molded from flame-retardant PA66 polyamide featuring elevated dielectric insulation breakdown voltage and thermal endurance, the housing prevents phase-to-phase flashover.

Copper alloy current bars with electrolytic tin or nickel plating ensure minimal contact resistance and reduce heat accumulation under continuous full-load operating currents.

PCB screw terminal technology across XC1016 and 128V model ranges

Xucheng PCB screw terminal connectors spanning XC1016, 128V, 128R, 300R, and 300V series solder directly onto printed circuit boards for industrial controllers, power supplies, and automation modules.

The clamping architecture utilizes an engineered brass elevator cage that exerts balanced force onto wire ends when tightened, eliminating strand shearing.

Contact pitch options range from 2.54 mm for compact monitoring assemblies up to 10.16 mm on high-power XC1016 units capable of handling continuous electrical currents up to 65 A.

Zinc-plated steel screws with combination drive heads deliver dependable torque retention without loosening during cyclic vibration.

Push-in spring clamp mechanisms for toolless electronic wiring

For accelerated wiring productivity and maintenance-free wire termination, Xucheng produces push-in spring clamp terminal blocks for printed circuit boards.

The retention mechanism incorporates a resilient spring fashioned from chromium-nickel spring alloy that presses the conductor against the copper busbar with controlled contact force. Direct push-in technology allows insertion of solid conductors or ferruled stranded wires without screwdrivers.

Continuous spring tension accommodates conductor relaxation and prevents joint loosening, proving vital in railway rolling stock, vibrating bulk sorters, and severe machine tool installations.

Two-piece pluggable terminal headers and detachable wire connectors

Xucheng two-piece pluggable terminal blocks comprise solder pin headers mounted on circuit boards and separable plug connectors equipped with screw or spring wire clamps.

This modular arrangement allows technicians to decouple electronic control modules, drive boards, and measurement nodes for routine servicing without disturbing field cable harnesses. Units are available in 3.81, 5.0, 5.08, and 7.62 mm contact pitches with 2 to 24 pole positions.

Polarized housing profiles eliminate reversed mating errors, while optional lateral threaded flange fasteners provide mechanical retention against pulling forces.

XCDS knife disconnect terminal modules for secondary measurement loops

For secondary current transformer circuits, relay protection panels, and instrumentation wiring, Xucheng manufactures XCDS-2.5 and XCDS-25 knife disconnect terminal blocks.

A hinged insulating lever equipped with an internal metallic contact blade allows technicians to open circuits for maintenance checks without undoing screw terminations or detaching wires. Integrated test sockets accommodate multimeter probe tips for diagnostic monitoring.

Visual indication of disconnect switch position prevents operator confusion and avoids hazardous open-circuit overvoltage on current transformer secondary windings.

Heavy-duty barrier terminal blocks with protective shield covers

Xucheng barrier terminal blocks are monolithic dielectric strips engineered with tall insulating ribs between terminal poles, designed for terminating power cables fitted with ring or spade compression lugs.

The design provides extended creepage paths and broad electrical clearances, preventing flashover when connecting power conductors handling up to 600 V and currents up to 100 A.

Each terminal strip is supplied with a transparent snap-on polycarbonate cover that protects operators from contact with energized busbars while keeping out metallic debris, moisture, and conductive dust within industrial switchboards.
