Electrical Connector Assembly With Extracted Solder Pegs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies with solder pegs face challenges in downsizing due to the space required for accommodating solder pegs, especially when both connectors have them, which complicates secure bonding and conductive functions.
Innovation Solution
The design incorporates a plug connector with conductive terminals arranged in rows and a receptacle connector with solder pegs positioned at an equidistant pitch matching the terminal pitch, allowing for reduced connector size and enhanced bonding strength without the need for additional solder pegs in the plug connector, utilizing synthetic resin housings and copper alloy terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solder pegs are provided in both electrical connectors, then bonding strength is improved, but connector size increases and downsizing becomes difficult
Solution Approach 1:
The invention extracts the solder peg function from one of the connectors (specifically, the plug connector is designed without solder pegs while the receptacle connector includes them). This selective extraction maintains the necessary bonding strength through soldering while removing the space-consuming components from one connector, thereby enabling downsizing of the overall connector assembly.
2Reliability
If solder pegs are provided in both electrical connectors, then mounting reliability is improved, but board occupancy area increases
Solution Approach 1:
The invention removes solder pegs from the plug connector while retaining them in the receptacle connector. This extraction approach maintains mounting reliability because the receptacle connector's solder pegs provide sufficient bonding strength, while simultaneously reducing the board occupancy area by eliminating redundant solder peg structures from one connector.
3Stability of the object's composition
If solder pegs are provided in both electrical connectors, then structural stability is improved, but device complexity increases
Solution Approach 1:
The invention simplifies the connector structure by extracting solder pegs from the plug connector. This reduces device complexity by eliminating unnecessary components and assembly steps while maintaining structural stability through the presence of solder pegs in the receptacle connector, which provides the necessary mechanical support and electrical connection.
