Rectangular Cable Assemblies

1. Overview

Rectangular cable assemblies are engineered interconnect solutions featuring rectangular-shaped connectors and integrated cables. They enable reliable signal, data, and power transmission in electronic systems. These assemblies are critical in modern technology for their compact design, high-density connectivity, and robust performance in demanding environments.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
D-Subminiature	Metal-shielded, screw-locking design	Industrial computers, military equipment
IDC (Insulation Displacement)	Tool-less termination, flat cable compatibility	Telecom switches, HVAC systems
Board-to-Board	Low-profile, high-pin-count options	Servers, medical imaging devices
Ribbon Cable	Parallel signal routing, flexible dielectric	Computer peripherals, test equipment

3. Structure and Components

Typical construction includes:

Contact elements: Phosphor bronze or beryllium copper with gold/silver plating
Insulation: High-temperature thermoplastic (e.g., LCP, PBT)
Shielding: Braided copper or conductive polymer layers
Strain relief: Molded thermoplastic overbraiding
Connector housing: Glass-filled nylon for mechanical stability

4. Key Technical Parameters

Parameter	Typical Range	Importance
Rated Voltage	50V - 600V	Ensures dielectric safety
Current Capacity	1A - 15A per contact	Determines power handling
Contact Resistance	5-20m	Impacts signal integrity
Insulation Resistance	100M - 10G	Prevents leakage currents
Operating Temperature	-55 C to +125 C	Environmental reliability
Mating Cycles	500 - 5000 cycles	Durability indicator

5. Application Fields

Primary sectors include:

Computer & Peripherals: Server backplanes, GPU interconnects
Telecommunications: 5G base stations, optical network terminals
Industrial Automation: PLC interfaces, robotic controllers
Medical Equipment: MRI scanners, diagnostic devices
Transportation: EV battery management systems, avionics

6. Leading Manufacturers

Manufacturer	Key Products
Amphenol Corporation	D-Sub 90 PCB Mount Series
TE Connectivity	MATE-AX High-Speed Backplane Cables
Molex LLC	PicoBlade 0.8mm Wire-to-Board Cables
