190003499855 24N 7-Pin Trailer Socket for HOWO Trucks

Optimized Performance for Heavy-Duty Applications

When connecting trailers to your 190003499855 equipped HOWO truck, the 24N Type 7-Pin Socket delivers uncompromised electrical conductivity. The corrosion-resistant brass terminals maintain stable voltage flow even during extended hauls. Engineered with a secure locking collar mechanism, this HOWO-specific connector prevents accidental disconnections from vibration and road impact. Each pin assignment corresponds to crucial trailer functions:

• Dedicated circuits for brake lights and indicators
• Reverse light control channel
• Electric brake controller interface
• Continuous 12V power supply
• Auxiliary charging line

This OEM 190003499855 socket meets strict voltage drop standards, ensuring your trailer lighting system remains fully operational during nighttime operations or low-visibility conditions. Truck operators report significantly reduced electrical issues after replacing worn connectors with genuine 24N Type parts.

Engineering Excellence for Harsh Environments

Developed for HOWO’s rugged truck platforms, the 7-Pin Trailer Socket 190003499855 features a composite housing with IP67 waterproof rating. This critical specification prevents moisture damage during rainy operations or truck washes. Unlike aftermarket alternatives, this 24N Type connector undergoes extreme thermal testing to maintain flexibility in sub-zero temperatures while preventing deformation in desert heat.

The integrated dust shield automatically closes when disconnected, keeping debris out of pin chambers. HOWO mechanics recommend the OEM 190003499855 socket for its precisely calibrated tension springs that ensure consistent pressure on trailer plugs through thousands of connection cycles. This 24N Type design consideration prevents the overheating issues common in inferior sockets.

At highway speeds, the aerodynamic socket shape reduces wind drag while preventing water pooling. For HOWO fleet managers, durability metrics show this 7-pin connector lasts 40% longer than competitors under equivalent hauling conditions.

Universal Compatibility with Modern Trailers

The 190003499855 24N Type connector supports all modern 7-pin trailer configurations including:

• LED-equipped flatbed trailers
• Refrigerated cargo units
• Hydraulic dump trailers
• Multi-axle heavy equipment haulers

Installation teams confirm the exact mounting bracket alignment with 190003499855 enables tool-free swap-outs on HOWO tractor units. The polarized socket keyway prevents incorrect plug insertion, a crucial safety feature during night operations.

This 24N Type solution incorporates integrated surge protection that safeguards truck electronics from trailer-side power spikes. For mixed fleets, it maintains compatibility with standard 7-way adapters while meeting ECE R55 European trailer coupling regulations.

Operational Benefits and Cost Savings

HOWO operators using the genuine 190003499855 7-Pin Socket report measurable performance improvements:

• Elimination of intermittent light failures
• 26% reduction in trailer connection time
• Extended service intervals exceeding 300,000 km

The connector’s vibration damping system absorbs chassis resonance that typically wears socket contacts in heavy trucks. Maintenance records prove this OEM 24N Type part requires fewer replacements, reducing long-term operational costs for HOWO fleets.

Independent testing shows the 190003499855 withstands current loads exceeding 30A per pin without degradation. This electrical margin prevents circuit issues when powering trailer-mounted equipment like liftgates or hydraulic pumps.

Optimized Design Features

Beyond electrical specifications, the HOWO 190003499855 socket incorporates user-centered design improvements. The color-coded wiring terminal block simplifies connections while resisting rotation from wiring torque. An inspection window allows technicians to verify correct pin alignment without disassembly.

Each component in this 24N Type system undergoes stringent validation:

• Thermal cycling (-40¡ãC to +125¡ãC)
• 1,000-hour salt spray resistance
• UV stability for sun-exposed installations
• Vibration testing matching HOWO chassis dynamics

Logistics companies using this OEM 190003499855 part report reduced roadside service calls related to trailer lighting failures. Its field-proven reliability makes it the preferred choice for cross-border shipping fleets operating HOWO trucks across varying climate zones.

Installation Considerations

Deploying the 190003499855 socket requires standard HOWO mounting locations without modification. Technicians should use weatherproof gaskets to maintain the housing’s protective ratings. This 24N Type connector provides color-matched wiring:

• Yellow: Left turn signal
• Green: Right turn signal
• Brown: Tail lights
• White: Ground connection
• Blue: Electric brakes
• Red: Battery charge line
• Black: 12V auxiliary

Proper harness routing prevents tension on the socket bracket during cab-trailer articulation. Routine maintenance includes dielectric grease application every service interval to maintain moisture protection.
