Position Fixer for Electrical Connector Terminal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in accurately inserting conductive terminals into printed circuit boards due to bending issues caused by the length of the terminals, which complicates the mounting process and increases the risk of damage.
Innovation Solution
An electrical connector design featuring a position fixer with through holes that retain the pin ends of conductive terminals, allowing for stable positional alignment and insertion into vias on the printed circuit board, with the position fixer moving up to the mounting surface during assembly to ensure secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the conductive terminals are made long to extend beyond the housing for connection, then the electrical connector can be mounted onto the printed circuit board, but the exposed terminals are prone to bending and difficult to insert accurately
Solution Approach 1:
The position fixer is used to preliminarily position the conductive terminals before insertion, maintaining their exact alignment with the vias. This preliminary positioning action ensures that even though the terminals extend beyond the housing, they remain accurately aligned and resistant to bending during the insertion process.
2Length of moving object
If the conductive terminals are made long to extend beyond the housing, then the electrical connector can be mounted onto the printed circuit board, but the terminals are prone to bending under external forces
Solution Approach 1:
The position fixer acts as an intermediary component between the conductive terminals and the housing. It provides additional support and constraint to the exposed terminals, preventing them from bending under external forces while still allowing them to extend beyond the housing for proper connection.
3Strength
If a shield substrate is used to provide mechanical support and positioning, then the conductive terminals are supported, but the exposed terminal length remains relatively long and still bends
Solution Approach 1:
The position fixer serves as an intermediary component that works in conjunction with the shield substrate. While the shield substrate provides general mechanical support, the position fixer specifically addresses the positioning of the exposed terminals, ensuring they maintain accurate alignment with the vias throughout the insertion process.
4Stability of the object's composition
If the conductive terminals are kept stationary relative to the housing, then the positional relationship is stable, but the exposed terminals remain long and subject to bending
Solution Approach 1:
The position fixer acts as an intermediary that enhances the stability of the positional relationship between the conductive terminals and the housing. It provides additional constraint and support to the exposed terminals, preventing bending while maintaining their stable positional alignment for accurate insertion.

AI summary
An electrical connector (10) adapted for being mounted onto a printed circuit board (PCB) including a number of vias. The electrical connector includes an insulative housing (200) having a board mounting surface (12), a contact module (400) assembled to the insulating housing (200) and including a number of conductive terminals (403), and a positioning fixer (300) mounting to the conductive terminals. Each of the conductive terminals includes a pin end extending beyond the mounting surface for being inserted into one of the PCB vias. The position fixer (300) has a plurality of through holes (301) each retaining to a corresponding pin end (405) prior to the position fixer (300) being moved up to the mounting surface when the electrical connector is mounted to the PCB.
