[Product Overview] DC-022C Cylindrical Pin Threaded Nut Fixed Panel-Mount DC Power Socket

DC-021C / DC-022C is a DC power socket (female connector) designed for high-reliability wiring requirements with cylindrical solid pin threaded panel-locking design5.5×2.1mm and and 5.5×2.5mm Standard adapter power plug, fully aligned with international general-purpose Panel Mount high-performance industrial-grade connector standards.

The core advantage of DC-022C lies in its tail, which adoptsa robust solid cylindrical/pin terminal (Solid Pin Terminal), completely solving the pain point of traditional thin solder tabs being prone to bending or breaking under strong tension or high-frequency vibration. The body is equipped withFine thread and hexagonal metal nutSimply make a round hole in the equipment panel for a tight and secure locking installation.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. Sturdy solid post terminals, resistant to bending with strong overload capacity

The tail pins feature a high-conductivity copper alloy solid post design, offering high mechanical strength. They do not bend or break under assembly tension or external vibration, and can withstand greater transient overload currents.

2. Circular threaded panel locking, reliable fastening and anti-loosening

The housing is equipped with precision-pitch threads and a hexagonal metal nut. The hole is easy to create, the locking force is evenly distributed, and with a washer it can withstand strong mechanical vibration, ensuring the connector remains firmly attached to the panel during repeated insertion and extraction.

3. Front metal collar protection, wear-resistant and impact-resistant

The socket interior and front edge feature a metal bushing that effectively absorbs lateral stress during power plug insertion and extraction, preventing angled insertion from wearing the plastic housing and greatly extending the connector's service life.

4. High-impact, flame-retardant engineering plastic base

Injection-molded from high heat-resistant engineering plastic that meets UL94V-0 flame retardant rating, with a high heat deflection temperature. During soldering or high-load operation, the housing base remains stable, does not melt or deform, and offers excellent insulation performance.
