Electrical Connector Asymmetry for 90-Degree Module Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face difficulties in arranging and connecting multiple modules due to differences in the direction of connector orientation relative to the board and between modules, especially when the angles are approximately 90 degrees, making it challenging to establish efficient electrical connections.
Innovation Solution
A connector design featuring a housing with parallel grooves and terminals that allow for easy alignment and connection of multiple modules, including a guide groove for board fixation and plate spring terminals that facilitate secure electrical contacts, enabling easy stacking and secure connections between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are connected via sockets with different directions for board connection and connector-to-connector connection, then electrical connection is achieved, but the arrangement of connectors becomes difficult especially when directions differ by approximately 90 degrees
Solution Approach 1:
The connector housing features an asymmetric design with a first contact surface and a second contact surface positioned at different locations and orientations. The first contact surface is configured for connection with a first neighboring connector while the second contact surface is configured for connection with a second neighboring connector, allowing connectors to be arranged in different spatial directions without requiring separate socket mechanisms for each connection direction.
2Adaptability or versatility
If multiple connectors are arranged on a board, then electrical connections between modules are established, but the complexity of arrangement increases when connectors must connect in different directions
Solution Approach 1:
Each connector is designed with multiple contact surfaces (first contact surface and second contact surface) that can connect to neighboring connectors in different directions. This multi-functional design allows a single connector type to serve multiple connection purposes, enabling versatile arrangement patterns on the board without requiring different connector variants for different connection directions.
3Reliability
If connectors use traditional socket-based connections, then electrical connection is achieved, but the ease of assembly and installation is reduced
Solution Approach 1:
The connector integrates multiple connection functions into a single unified structure. The housing combines the first contact surface, second contact surface, and mounting features (such as the mounting hole and engagement protrusions) into one integrated component, eliminating the need for separate socket assemblies and simplifying the assembly process while maintaining reliable electrical connections.
