Black 4-Pin Dual-Row Connector to Insulated Fork Spade Terminal Power Harness for Electronic Control Modules

• This product is an optimized B2B industrial Power Feed Sub-Assembly Wire Harness, bridging a dual-row black 4-pin (2x2 grid) locking friction receptacle housing over to highly reliable vinyl-insulated fork spade (U-type) terminals. It is built using heavy-gauge UL1007/UL1015 18AWG stranded power leads in standard contrasting red and black insulation, bundled neatly with a central nylon zip-tie constraint.

• Target Application Scenarios: This power harness is commonly engineered for Industrial Switching Power Supplies (SMPS) to route DC rail power over to internal electronic control boards. It is widely used in Solar Inverter Modules, Server Rack Power Distribution Units (PDUs), and Industrial Automation Equipment Terminal Blocks where incoming electrical lines transition from a screw-down barrier rail to a standard multi-pin PCB socket header.

• Technical Pain Points Solved: Directly wrapping raw stripped wire ends around screw blocks is highly inefficient and causes wire strand fraying, strands shorting across terminals, and loose connections. The insulated fork spade terminals slip effortlessly beneath barrier screws for a gas-tight, rugged termination. It also completely addresses accidental polarity inversion (which instantly ruins sensitive downstream microcontroller chips) through stark red/black color-coding paired with a custom printed heat-shrink tracking marker tube that marks the exact circuit termination point.

Key Features

• Insulated barrels protect against accidental shorting across tightly packed barrier strips.
• High-retention connector shell resists heavy pulling and operational shocks.
• Distinct color separation simplifies installation diagnostics.
• Gas-tight industrial crimps prevent internal contact resistance and heat build-up.
• Pre-labeled for fast component sorting during warehouse pick-and-pack.
