Reinforced Connector Housing for Stable Contact Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deformation of the housing in connectors due to outward force from movable pieces reduces contact load of contact pins, leading to suboptimal performance.
Innovation Solution
A connector with a reinforcing member having a plate-like frame part surrounding the protruding part of the housing, attached orthogonal to the insertion-extraction direction, to reduce deformation and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the housing walls are not connected to each other to form a space for accommodating another component, then the housing can accommodate additional components, but the walls are more likely to be deformed by force from movable pieces
Solution Approach 1:
A reinforcing member is introduced as an intermediary element between the movable pieces and the housing walls. This reinforcing member absorbs and distributes the outward force from the movable pieces, preventing direct transmission to the housing walls and thus preventing deformation while maintaining the open structure needed for component accommodation.
Solution Approach 2:
The housing structure is segmented by dividing it into functional zones: the main housing body and the reinforcing member. The reinforcing member acts as a separate structural element that can be independently optimized for strength while the housing maintains its open configuration for component accommodation.
2Volume of stationary object
If the housing walls are not connected to each other, then space for components can be formed, but contact load of contact pins is reduced
Solution Approach 1:
The reinforcing member serves as a mediator that maintains housing structural integrity. By distributing the forces from movable pieces, it prevents housing deformation that would otherwise reduce contact load, thereby ensuring reliable contact performance while preserving the internal space configuration.
3Stability of the object's composition
If a reinforcing member with frame part surrounding the protruding part is added, then housing deformation is reduced, but device complexity increases
Solution Approach 1:
The reinforcing member employs a thin plate-like frame structure that provides significant structural reinforcement through its geometric configuration rather than through massive material addition. This plate-like design maintains housing stability while adding minimal structural complexity.
Solution Approach 2:
The reinforcing member utilizes a two-dimensional plate-like frame structure that surrounds the protruding part in plan view. This dimensional approach provides comprehensive structural support through a relatively simple geometric form, avoiding the need for complex three-dimensional structures.
4Stability of the object's composition
If the frame part is installed on the surface orthogonal to insertion-extraction direction, then deformation is reduced, but connector size increases
Solution Approach 1:
The plate-like frame structure of the reinforcing member provides effective structural reinforcement through a thin profile. This thin-film approach reduces housing deformation while minimizing the increase in connector thickness, as the reinforcement is achieved through geometric configuration rather than substantial material addition.

AI summary
A connector that is mounted on an external mount substrate and in or from which an external pluggable substrate is inserted or extracted in an insertion-extraction direction Die includes: pin groups each including a plurality of aligned contact pins; an outer housing holding the pin groups and a frame attached to the outer housing. The outer housing has a main body and a protruding part which protrudes in the insertion-extraction direction Die from the main body and in which a slot opening in or from which the pluggable substrate is inserted or extracted is formed. The frame surrounds the whole circumference of the protruding part and is installed on an installation surface of the main body substantially orthogonal to the insertion-extraction direction Die.
