PCB Connector Identification Layer for Misinsertion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PCB connectors lack distinct identification features, leading to confusion and increased assembly time, especially for users unfamiliar with computer installation, as similar connectors can be easily misinserted due to lack of clear differentiation.
Innovation Solution
A PCB connector with an identification layer featuring distinct characters and a contrasting background color, along with a distinguishable mark surrounding specific contact pins, to facilitate easy recognition and prevent misinsertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional PCB connectors without distinct identification features are used, then the device complexity is reduced, but the ease of operation deteriorates due to confusion and difficulty in distinguishing connector types
Solution Approach 1:
The patent applies color changes by providing an identification layer with a background color different from the character color. This allows users to easily distinguish different connector types through color-coded identification, improving ease of operation without significantly increasing device complexity
Solution Approach 2:
The identification layer acts as an intermediary element between the connector body and the user. It provides visual information (characters and color contrast) that mediates the interaction between the user and the connector, making identification easier without modifying the core connector structure
2Productivity
If traditional PCB connectors without distinct identification features are used, then the manufacturing process remains simple, but the loss of time increases due to longer assembly times required for connector identification and installation
Solution Approach 1:
The identification layer with pre-printed characters and color contrast is prepared in advance during manufacturing. This preliminary action of providing visual identification features allows users to quickly identify connector types during assembly, reducing the time needed for identification and installation
Solution Approach 2:
The use of color contrast between the background and characters provides immediate visual differentiation, enabling faster identification of connector types and functions, thereby increasing assembly speed and reducing time loss during installation
3Reliability
If similar connectors without distinct identification are used, then the device complexity is minimized, but the reliability deteriorates due to risk of misinsertion of wrong connector types
Solution Approach 1:
The identification layer uses color contrast to provide clear visual distinction between different connector types. This allows users to reliably identify the correct connector type and function, preventing misinsertion errors without requiring complex structural modifications to the connectors themselves
Solution Approach 2:
The identification layer introduces asymmetry through the placement and design of characters and color patterns on specific sides of the connector body. This asymmetric identification system provides reliable visual cues for correct orientation and type identification, enhancing reliability while maintaining simple connector structures

AI summary
A connector for connection to a printed circuit board includes a body, a plurality of contact pins on both side of the body, and an identification layer joined to one side of the body. In particular, the identification layer defines a plurality of holes for insertion of the contact pins. Further, the identification includes at least one character thereon for identifying function or use of the connector and a background in a color different from that of the character.
