Simplified Central Contact for Power Connector Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power connectors have complex central contact configurations that complicate assembly, making them inconvenient to assemble.
Innovation Solution
A simplified central contact design with a unified columnar configuration, featuring an engaging portion, retaining portion, and connecting portion, which is easily rotated into place within the insulative housing, utilizing a projection with a retaining slot and supporting portion for secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the central contact has a rectangular retaining portion with columnar mating and soldering portions, then the central contact can be retained in the housing, but the configuration becomes complex and assembly becomes inconvenient
Solution Approach 1:
The central contact is designed with a uniform columnar configuration throughout its entire length, including the retaining portion, mating portion, and soldering portion. This homogeneous design eliminates the complexity of transitioning between different cross-sectional shapes (rectangular to columnar) while maintaining effective retention through the columnar retaining portion that fits into the receiving hole.
2Adaptability or versatility
If the central contact has a complex configuration with different contours, then it can fulfill multiple functions, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The central contact is divided into distinct functional segments (retaining portion, mating portion, soldering portion) that are all unified under a consistent columnar geometry. This segmentation allows each portion to perform its specific function while maintaining overall simplicity for assembly.
3Reliability
If the central contact uses a rectangular retaining portion, then it can be retained in the housing, but the assemblage process becomes inconvenient
Solution Approach 1:
The central contact maintains a consistent columnar cross-section throughout, eliminating the need to manufacture and assemble different-shaped portions. This homogeneous design simplifies the manufacturing process and makes assembly more convenient while still providing reliable retention through the columnar retaining portion.

AI summary
An electrical connector includes an insulative housing, a first contact and a central contact being of a uni-configuration respectively retained in the housing. The housing has a mating cavity extending through a front face thereof, a receiving hole extending through a rear face thereof, and a projection rearwards projecting from the rear face. The projection defines a retaining slot opened sideward and a supporting portion disposed between the retaining slot and the rear face of the housing, a connecting portion of the central contact climbs over the supporting portion and runs through the retaining slot.
