Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable connectors in the related art suffer from misalignment of cable modules due to lack of positioning, which reduces manufacturing yield.
Innovation Solution
A cable connector design featuring a base portion with ribs and positioning blocks, a metal shielding piece, and conductive terminals, where a metal bar in the cable module abuts against positioning surfaces to limit its direction, ensuring proper alignment and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable module is mounted to the insulating body without positioning structures, then the device complexity is reduced, but the manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The positioning block is pre-formed as an integral part of the base portion, creating a positioning surface before the cable module is mounted. This preliminary positioning structure guides the cable module into correct alignment during installation, preventing misalignment without requiring complex adjustment mechanisms.
Solution Approach 2:
The positioning block acts as an intermediary element between the base portion and the cable module. It provides a positioning surface that mediates the alignment relationship, ensuring the cable module is correctly positioned relative to the conductive terminals without direct complex interfacing between the base and cable module.
2Manufacturing precision
If positioning structures are added to the base portion, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The positioning block is merged with the base portion as an integral structure, eliminating the need for separate positioning components. This combining approach provides precise positioning functionality while avoiding the complexity of additional independent parts and their associated assembly steps.
Solution Approach 2:
The base portion serves multiple functions: it provides structural support, electrical connection pathways, and precise positioning through the integrated positioning block. This multi-functionality reduces the need for separate specialized components, maintaining simplicity while achieving accurate alignment.
3Ease of manufacture
If the cable module lacks positioning, then the ease of manufacture is improved, but the productivity deteriorates due to reduced yield
Solution Approach 1:
The positioning surface is pre-formed on the positioning block before assembly. This preliminary preparation ensures that when the cable module is installed, alignment is automatically achieved without requiring post-assembly adjustments or rework, thereby maintaining ease of manufacture while improving yield.
Solution Approach 2:
The positioning block enables the cable module to self-align during installation. The positioning surface automatically guides the cable module into the correct position without requiring external positioning tools or complex alignment procedures, improving both ease of manufacture and manufacturing yield.

AI summary
A cable connector includes a base portion, a metal shielding piece, a number of first conductive terminals and a first cable module. The base portion includes a first surface, a first rib protruding beyond the first surface along a first direction and a first positioning block further protruding beyond the first rib along the first direction. The first positioning block is provided with a first positioning surface. The first cable module includes a first metal bar and a number of first cables. The first metal bar is provided with a first abutting surface. The first metal bar is supported on the first surface of the base portion. The first abutting surface of the first metal bar abuts against the first positioning surface of the first positioning block along a second direction to limit the first cable module in the second direction. The first metal bar is in contact with the metal shielding piece.
