Three-Housing Compression Connector Terminal Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors often cause terminals to break off the housing due to inadequate securing mechanisms.
Innovation Solution
A compression connector design featuring an insulative housing with a base and matching housing, where terminals with spring sections and contacting sections are retained between tubers and notches, preventing them from coming off by providing a secure and elastic fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals are secured by extending retaining portions from the base portion, then terminals can be retained in the housing, but terminals may break off the housing
Solution Approach 1:
The housing is divided into three separate housing portions (first, second, and third housing portions) that are assembled together. The retaining portions of the terminals are retained between these segmented housing portions, distributing the retention force across multiple components rather than relying on a single housing structure, thereby preventing terminal breakage while maintaining secure retention.
2Reliability
If terminals are securely retained in the housing, then connection reliability improves, but the complexity of the housing structure increases
Solution Approach 1:
The housing is segmented into three separate portions that can be manufactured independently and then assembled together. This segmentation allows each portion to be optimized for its specific function (e.g., first housing portion for retention, second for support, third for sealing) while maintaining overall structural integrity and connection reliability.
Solution Approach 2:
The three housing portions are nested or fitted together in a layered configuration, with each portion contributing to the overall retention mechanism. The first housing portion retains the retaining portions, the second housing portion provides additional support, and the third housing portion completes the enclosure, creating a nested structure that enhances reliability without excessive complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively secures terminals within the housing, preventing breakage and allowing for reliable connection and adjustment during PCB assembly, ensuring stable and durable connections between circuit boards.
Implementation Method 1
two spring sections formed at two opposite sides of the retaining section

AI summary
A compression connector for connecting two PCBs includes an insulative housing and a plurality of terminals received in the housing. Each terminal includes a retaining section and two spring contacting sections extending from opposite ends of the retaining section and exposing beyond mating surface of the housing. The insulative housing includes a base housing and a pair of matching housing sandwich the base housing from opposite directions to retain the retaining sections in said three housings such that the terminals can be well retained therein.
