Connector Contact Structure for Stable Header Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As electronic devices are miniaturized, traditional board-to-board connectors face challenges in maintaining contact stability and minimizing space between contact structures, leading to increased length or width, which hinders further miniaturization and can result in misalignment and plastic deformation.
Innovation Solution
A connector design featuring a one-contact point structure with a guide structure and bending portions that apply pressure to fix the header, ensuring contact stability and minimizing space between contact points, while preventing misalignment and plastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact structures are arranged in two rows to ensure contact stability, then contact stability is improved, but the overall width of the connector increases
Solution Approach 1:
The patent transitions from a two-row contact structure arrangement to a one-row arrangement by utilizing vertical stacking of contact points within the same horizontal position. This dimensional reorganization allows contact structures to be arranged in one row while maintaining stability through the first and second contact points positioned at different heights, thereby reducing connector width without sacrificing contact stability.
2Reliability
If the number of contact structures is increased to achieve contact stability, then contact stability is improved, but the overall length of the connector increases
Solution Approach 1:
The patent merges multiple contact structures into a single integrated contact structure that contains both a first contact point and a second contact point. This unified structure provides multiple contact points for stability while occupying the space of only one contact structure, thereby maintaining contact stability without increasing connector length.
3Reliability
If traditional two-contact point structure is used to ensure contact stability, then contact stability is improved, but the space between contact structures increases
Solution Approach 1:
The patent applies local quality by positioning the first contact point and second contact point at different vertical levels within the same horizontal footprint. This localized differentiation in contact point arrangement allows multiple contact points to be packed into minimal space, reducing the space between contact structures while maintaining contact stability through the multi-level contact configuration.
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 design achieves miniaturization of the connector, enhances contact stability, and prevents damage from misalignment by ensuring a short electrical path and secure fixation of the header, thereby maintaining reliable electrical connections.
Implementation Method 1
a first point of the first bending portion may come into contact with the first header, and, as the first bending portion is bended, the first bending portion may apply a pressure to the header in a first direction to fix the first header to the connector

AI summary
A connector according to various embodiments of the present disclosure comprises: a housing; an accommodation groove formed in one portion of the connector; a guide comprising a first guide firmed on the side surface of the accommodation groove and a second guide formed on the side surface of the accommodation groove to be spaced a certain distance from the first guide; and a first contact arranged between the first guide and the second guide, wherein the first contact comprises a first bending portion and a second bending portion. The guide is in contact with a header and guides the position of the header. A first point of the first bending portion is in contact with the header, and as the first bending portion is bent, the first bending portion applies the pressure to the header so that the header is fixed to the connector. A second point of the first bending portion may be in contact with a third point of the second bending portion. Other various embodiments are possible.
