Backplane Connectors - Accessories

1. Overview

Backplane connectors are critical components in electronic systems, providing modular interconnection between printed circuit boards (PCBs) and supporting high-density signal/power transmission. Accessories enhance their functionality through mechanical support, environmental protection, and performance optimization. These components are essential in telecommunications, data centers, and industrial equipment for ensuring reliable system architecture.

2. Major Types & Functional Classification

Type	Functional Features	Application Examples
Alignment Pins	Precision-guided insertion, anti-misalignment design	Telecom backplanes
Grounding Clips	EMI shielding, 360 contact	Military radar systems
Dust Covers	IP67-rated contamination protection	Outdoor base stations
Mounting Brackets	Vibration damping, load distribution	Industrial control cabinets
Test Adapters	Hot-swappable diagnostics interface	Data center maintenance

3. Structural Composition

Typical construction includes:

Mechanical components: Precision-machined alignment guides and stress-relief brackets
Electrical elements: Gold-plated contact points and EMI gaskets
Material composition: LCP (Liquid Crystal Polymer) insulation with UL94 V-0 rating

4. Key Technical Specifications

Parameter	Typical Range	Importance
Current Rating	1-5A per contact	Power transmission capability
Dielectric Strength	1,000-2,500VAC	Electrical safety margin
Contact Resistance	<10m	Signal integrity maintenance
Insertion Force	20-80N	Usability and durability
Operating Temp	-55 C to +125 C	Environmental reliability

5. Application Fields

Primary industries:

Telecommunications: 5G base stations, optical switches
Data Centers: Server racks, storage arrays
Industrial Automation: PLC backplanes
