Electrical Connector Integrating Cable and PCB Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors occupy significant space and have complex assembly processes due to the need for multiple cables and additional circuit boards, especially when connecting high-speed signals and power supplies.
Innovation Solution
An electrical connector design featuring a first insulating housing with conductive terminals connected to wires for high-frequency signal transmission and second conductive terminals directly connected to a circuit board for low-speed signals or power supply, reducing the need for additional cables and simplifying assembly by using a second insulating housing that inserts into the first housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If all connector terminals are connected to other electronic apparatus by means of cables with the riser card serving only as a fixed connector, then the connector can be assembled, but it occupies a large space and requires complex assembly and cable sorting work
Solution Approach 1:
The patent merges the functions of cable connections and circuit board connections into a single connector structure. The connector includes both cable terminals and circuit board terminals integrated in one housing, eliminating the need for separate riser cards and reducing assembly complexity while conserving space.
Solution Approach 2:
The connector is designed with multi-functionality to serve both cable connections and circuit board connections simultaneously. By incorporating different terminal types (cable terminals and circuit board terminals) in one connector, it replaces the need for separate connectors and reduces the overall system complexity.
2Adaptability or versatility
If additional circuit boards are used to connect power supply or low-speed control signal terminals, then all connection types can be accommodated, but the assembly becomes more complex
Solution Approach 1:
The patent combines power supply terminals, low-speed control signal terminals, and high-speed signal terminals into a single connector housing. This integration eliminates the need for additional circuit boards and reduces assembly complexity while maintaining the ability to accommodate multiple connection types.
Solution Approach 2:
The connector is designed as a universal interface that can handle different types of connections (power, low-speed signals, high-speed signals) through different terminal configurations within the same connector, thereby accommodating all connection types without requiring separate components.
3Adaptability or versatility
If more cables are used to connect all terminals, then complete functionality is achieved, but cable sorting work becomes complex
Solution Approach 1:
The patent merges cable connections and circuit board connections into a single integrated connector structure. By providing both cable terminals and circuit board terminals in one connector, it reduces the number of separate cables needed and simplifies cable sorting work while maintaining complete functionality.
