Cable Connector Assembly Segmented Control Wires

Solution Overview

Problem

The manufacturing process of soldering crossed control wires in SAS connector assemblies is complicated and inefficient, requiring separate soldering of core wires which increases complexity and time.

Innovation Solution

A cable connector assembly design that uses a flat cable with signal and control wires, where the control wires are arranged independently to connect between printed circuit boards via a connecting member, eliminating the need for crossed soldering and simplifying the assembly process by using a flat cable instead of core wires.

1Reliability

If crossed control wires are used to connect between printed circuit boards, then electrical connection between boards is achieved, but the soldering process becomes complicated and manufacturing time increases

Engineering Contradiction:

Improveelectrical connectionVSAvoidsoldering process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The control wires are segmented into two independent groups: first control wires connecting the first PCB to the third PCB, and second control wires connecting the second PCB to the fourth PCB. This segmentation eliminates the need for crossed soldering connections, simplifying the manufacturing process while maintaining reliable electrical connections between corresponding circuit boards.
