Electrical Plug Connector With Elastic Spring Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector parts fail to securely fasten connecting lines with varying cross-sectional widths, leading to mechanical stress from vibrations, such as in motor vehicles, resulting in deteriorated or failed connections.
Innovation Solution
A clamping bracket with molded-on elastic spring arms that can be positioned in two latching modes, allowing easy assembly and secure fixation of connecting lines with different cross-sectional widths by pressing them against the inner walls of the protective housing, ensuring vibration-resistant attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with fixed receiving recesses is used to fasten connecting lines, then the connecting lines are securely fastened against vibrations, but the connector only accepts connecting lines with a specific cross-sectional width and cannot accommodate varying line sizes
Solution Approach 1:
The patent applies the dynamics principle by making the receiving recesses dynamically adjustable through elastic deformation. The housing material is designed to be elastically deformable, allowing the receiving recesses to adapt their shape and size to different connecting line cross-sections. When a connecting line is inserted, the housing deforms elastically to surround the line, and the locking mechanism engages with the deformed housing to secure it. This dynamic adaptation enables the connector to reliably fasten connecting lines of various cross-sectional widths while maintaining vibration resistance.
2Adaptability or versatility
If the receiving recesses are made elastic to accommodate different line sizes, then adaptability to different cross-sections is improved, but the mechanical strength and precision of the locking mechanism deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the connector into distinct functional components: the housing that provides elastic adaptation, and the separate locking mechanism that provides secure fastening. The locking mechanism includes independent locking elements that can engage with the deformed housing at specific locking positions. This segmentation allows the elastic housing to adapt to different line sizes while the rigid locking mechanism maintains its strength and precision for reliable securing, resolving the contradiction between adaptability and mechanical strength.
3Reliability
If a precise shape adjustment mechanism is used to enclose connecting lines, then vibration resistance is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies parameter changes by utilizing the material property parameter of the housing - specifically its elastic modulus and deformability. Instead of complex mechanical shape adjustment mechanisms, the housing material is selected and designed to naturally deform elastically when a connecting line is inserted. This change in material parameter allows the housing to automatically adapt its shape to surround different line cross-sections, and the locking mechanism simply needs to engage at predetermined locking positions. This approach significantly reduces device complexity while maintaining vibration resistance through the elastic怀抱 of the housing.
