Electrical Connector Housing Segmentation for Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for circuit boards face challenges in achieving different heights and withstanding external forces, as dividing the housing into sections for varying heights compromises holding power and structural integrity.
Innovation Solution
The electrical connector design features a housing divided into a receiving-side housing for contact portions and a board-side housing for terminal securing, where both are molded as a single unit, allowing for adjustable height settings in the simpler board-side housing without compromising holding power, and enabling the use of a single stock material for various connector types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the housing is divided into two sections (stationary housing and movable housing) to achieve different connector heights, then adaptability is improved, but holding power and structural integrity deteriorate
Solution Approach 1:
The housing is divided into two functional sections: a stationary housing that secures one end of the terminals to the circuit board, and a movable housing that contains the other end of the terminals and can move relative to the stationary housing. This segmentation allows different connector heights by adjusting the length of resilient portions while maintaining structural integrity through the integrated molding process
Solution Approach 2:
The stationary housing and movable housing are molded as a single integrated unit, combining both sections into one piece. This merging approach maintains holding power and structural integrity while allowing the resilient portions to provide the necessary movement and height adjustment capability
2Adaptability or versatility
If the stationary and movable housings are spaced apart to absorb offset, then adaptability is improved, but structural integrity deteriorates
Solution Approach 1:
The movable housing is designed to move relative to the stationary housing, creating a dynamic structure that can absorb offset. The resilient portions of the terminals enable this movement while the integrated molding maintains overall structural integrity and stability
3Adaptability or versatility
If the housing sections are spaced apart to achieve different heights, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is segmented into stationary and movable sections with distinct functions, allowing height adjustment through the length of resilient portions while maintaining a relatively simple overall structure through integrated molding

AI summary
Electrical connector for circuit boards provided with terminals having connecting portions configured to be connected to a circuit board at one end in the longitudinal direction of said terminals and contact portions configured to be placed in contact with a counterpart connector component at the other end, and a housing holding a plurality of said terminals in place in array form. Said housing having disposed therein the contact portions of the terminals, and formed such that it is divided into a receiving-side housing, which accommodates the contact portions and receives a counterpart connector component such that it is placed in contact with the contact portions, and a board-side housing, which holds the terminals in place in sections more proximal to the connecting portions than to the contact portions and which is mounted to a circuit board, and the receiving-side housing and the board-side housing are molded as a single unit.
