MiniPCI Connector Two-Piece Design for Angular Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MiniPCI connectors require the internet card to be pressed at a 20° angle for connection, making the process inconvenient and complicated, and involve a cumbersome buckling procedure for antenna connections.
Innovation Solution
A two-piece MiniPCI connector design with an upper and lower unit that allows the internet card to be easily fitted in either direction, featuring buckling portions and grooves for secure alignment and a foolproof mechanism to facilitate direct connections between the internet card and antenna connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the MiniPCI connector is formed in one-piece structure, then the connector structure is simple and manufacturing is easier, but the internet card has to be pressed at a 20° angle for connection which makes the connection process inconvenient and complicated
Solution Approach 1:
The MiniPCI connector is divided into two separate pieces: an upper connector body and a lower connector body. This segmentation allows the internet card to be inserted horizontally without requiring angular pressing, thereby improving connection convenience while maintaining manufacturing feasibility through modular assembly
2Volume of moving object
If the conventional one-piece MiniPCI connector is used, then the structure is compact, but the connection between internet card and antenna requires a cumbersome buckling procedure
Solution Approach 1:
The upper and lower connector bodies are combined through a buckling connection mechanism that integrates the antenna connector functionality. This merging allows the antenna connection to be accomplished simultaneously with the main connector assembly, eliminating the need for separate buckling procedures and reducing overall connection complexity
3Manufacturing precision
If the internet card is pressed at a 20° angle for connection, then the contacting terminals can be positioned correctly, but the connection process becomes inconvenient and time-consuming
Solution Approach 1:
The upper and lower connector bodies are pre-positioned with aligned contacting terminals and guiding structures. This preliminary arrangement ensures that when the internet card is inserted horizontally, the terminals automatically engage at the correct positions without requiring angular pressing, thereby reducing connection time while maintaining positioning accuracy

AI summary
An improved MiniPCI connector structure includes a mini area bus connector and a set of plate type antenna connector. The bus connector comprises an upper unit and a lower unit buckling to each other. The upper unit has a plurality of contacting terminals within, and the adjacent sides of contacting terminals protrude out of the opening of the upper unit to form adapting slot and plug; the flange of the upper unit has two buckling portions, and the lower unit has corresponding adapting slot and corresponding buckling portion corresponding to the contacting terminals and the buckling portions at the flange of the upper unit. Thus, the interne card can be adapted into the adapting slot of the upper unit and the buckling of the buckling portion and the corresponding buckling portion enables the upper unit joining with the lower unit as a mini area bus connector and a set of plate type antenna connector positioning on the circuit board.
