Cable Assemblies

Cable Assemblies play a key role in efficient connection and signal integrity in electronic systems.

1. Cable Assemblies Overview‌

‌Cable Assemblies‌ (cable assemblies) are pre-assembled integrated wiring harnesses composed of connectors, wires and insulation layers, which are used to achieve signal transmission or power connection between electronic devices.

Its core functions include: ensuring stable transmission of high-frequency/high-speed signals (such as RF coaxial cable assemblies), adapting to different interface standards (such as QSFP+ interfaces), and simplifying the complexity of internal wiring of equipment.

2. What are the Core Components of Cable Assemblies?‌

‌Connectors‌: Such as RF coaxial connectors, QSFP+ interfaces, etc., are responsible for docking with device ports.

‌Wire and insulation layer‌: The combination of conductor material (such as copper core) and insulation layer (such as PVC or Teflon) determines electrical performance and environmental resistance.

‌Protective structure‌: Some components need to add shielding layers or protective sleeves to resist electromagnetic interference or mechanical damage.

3. What are the Technical Process of Cable Assemblies？‌

1) ‌Manufacturing Process‌:

‌Crimp‌: The terminal and the conductor are fixed by a crimping tool, and the contact resistance between the conductor and the terminal must meet the standard.

‌Insulation Displacement Connection (IDC)‌: The terminal blade is used to pierce the insulation layer of the wire to directly contact the conductor, which is suitable for flat cable scenarios.

‌Solder‌: Including wave soldering, reflow soldering, etc., used for precision connection in high-density or high-frequency scenarios.

‌2) ‌Quality Inspection‌: Tensile test, appearance inspection (such as conductor length, terminal deformation) and electrical performance test (such as standing wave ratio) are required.

‌4. What are Cable Assemblies Used for？‌

‌Communication Equipment‌: RF coaxial cable assemblies are widely used in high-frequency signal transmission scenarios such as base stations and satellite communications.

‌Data Center‌: High-speed cables (such as 40G QSFP+ assemblies) are used for high-speed interconnection between servers and switches.

‌Industrial Equipment‌: Customized cable assemblies meet the requirements of high-temperature resistance and vibration resistance in complex environments. ‌
