Side-Mounted Connector With Pivoting Member For Reduced Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for mobile devices and electronic appliances face challenges in achieving a reduced overall height and stable electrical connection when mounted on a substrate's side surface, with poor holding forces leading to dislodgement under external forces.
Innovation Solution
A connector design featuring a housing with a ceiling portion and extension walls, a pivoting member with urging portions and anchoring holes, and contacts arranged in a crank shape, allowing for compact rotation and secure engagement with the substrate, ensuring the connector remains attached even under accidental external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the connector is mounted on the side surface of a substrate, then the overall height is reduced, but the holding force becomes insufficient and the connector may be dislodged under external forces
Solution Approach 1:
The connector is mounted on the side surface of the substrate rather than the top surface, utilizing the lateral dimension to reduce the overall height profile while maintaining functional integrity. This dimensional repositioning allows the connector to achieve a lower height without compromising its structural capabilities.
Solution Approach 2:
The housing is divided into distinct functional segments: a ceiling portion for covering contacts, extension walls for mounting attachment, and urging portions for contact pressure. This segmentation allows each part to optimize its specific function while contributing to the overall holding force and stability of the side-mounted connector.
2Length of stationary object
If the pivoting member is made compact to reduce height, then the overall height is reduced, but the operationality and ease of actuation deteriorate
Solution Approach 1:
The pivoting member is designed with dynamic characteristics that allow it to rotate smoothly between contact and non-contact positions. The urging portions are configured to provide appropriate mechanical advantage, enabling easy actuation despite the compact height. The pivoting motion is optimized to achieve full contact pressure within a limited angular range, maintaining operational ease while minimizing height.
3Strength
If the protection wall is added to prevent dislodgement, then the holding force is improved, but the device complexity increases
Solution Approach 1:
The protection wall is merged with the extension walls of the housing, forming an integrated structural element that serves dual purposes: providing mechanical strength to prevent dislodgement and maintaining the compact side-mounted profile. This integration avoids adding separate protective components, thereby reducing overall complexity while enhancing holding force.
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 connector achieves a reduced overall height and enhanced operationality by maintaining secure attachment to the substrate, preventing dislodgement and ensuring reliable electrical contact despite external forces.
Implementation Method 1
an elastic portion (46) for connecting the first piece (34) and the fulcrum portion (44), the contact portion (38), elastic portion (46), fulcrum portion (44) and connection portion (48) being arranged in the form of a crank
Implementation Method 2
a pivoting member (16) causing the contacts (14) to be elastically deformed and pressed against the connecting object

AI summary
A connector includes substantially H-shaped contacts; fixtures fixing the connector to a substrate on longitudinal ends; a housing having a ceiling portion covering contact portions of the contacts, a protection wall at the end of the ceiling portion on the fitting opening side for preventing raising of the ceiling portion on being accidentally forced upward, extension walls at the longitudinal ends for holding the fixtures, and slits each between the extension wall and a bearing for a pivoting member; and the pivoting member having an actuating portion, urging portions, and anchoring holes and mounted on the housing such that between the connection portions and the pressure receiving portions of the contacts the urging portions perform a compact pivotal movement with rotation axis moving. The connector is mounted on one side surface of the substrate to achieve more reduced overall height and superior operationality of the pivoting member.
