1. Overview

Power Entry Connectors - Accessories are complementary components that enhance the functionality, safety, and performance of power entry systems. These accessories include filters, fuse holders, mounting brackets, and cable management solutions. They play a critical role in ensuring safe electrical connections, electromagnetic interference (EMI) suppression, and compliance with international safety standards in devices ranging from consumer electronics to industrial machinery.

2. Major Types and Functional Classification

3. Structure and Composition

Typical components include: - Housing: Flame-retardant thermoplastics (e.g., PA66, PBT) or metal alloys - Contact Elements: Phosphor bronze or beryllium copper with gold/silver plating - Insulation: High-temperature resistant materials (up to 150 C) - Mounting Features: Threaded bushings, snap-in tabs, or PCB terminals - Protection Components: Built-in ferrite cores (for filters), fuse clips
