Conductive Terminal Assembly With Tenon Locking for Fast Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive terminals in existing connector assemblies suffer from insufficient bonding strength with the casing, leading to separation issues, and the assembly process is time-consuming due to the need for multiple steps to insert each terminal individually.
Innovation Solution
The conductive terminal design includes a contact arm, contact pin, extension part, and tenon structure, allowing for multiple terminals to be positioned and secured within accommodating grooves in the casing through a tenon structure that interlocks with mortise structures, enhancing bonding strength and enabling simultaneous insertion of multiple terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conductive terminals are assembled to the casing by conventional assembly methods, then the bonding strength between conductive terminals and casing is insufficient, but the assembly process is simple
Solution Approach 1:
The conductive terminal is segmented into distinct functional parts: contact arm, contact pin, extension part, and tenon structure. The tenon structure specifically segments the connection interface to provide enhanced bonding through a dedicated interlocking mechanism rather than relying on general assembly methods.
Solution Approach 2:
The tenon structure of the conductive terminal is nested within the mortise structure of the casing, creating a nested interlocking relationship. This nested configuration provides strong bonding strength while maintaining a compact overall structure.
2Manufacturing precision
If multiple conductive terminals are inserted into the casing individually through multiple assembling steps, then each terminal can be properly positioned, but the assembly process is time-consuming
Solution Approach 1:
Multiple conductive terminals are merged into a single integrated assembly unit with a common base structure. This merged assembly is inserted into the casing as one unit, combining multiple insertion operations into a single step while maintaining proper positioning of each terminal through the integrated structure.
Solution Approach 2:
The conductive terminals are preliminarily positioned and fixed to the common base structure before the final assembly insertion. This preliminary action ensures proper positioning is achieved during manufacturing, and the pre-assembled unit is then quickly inserted into the casing in a single operation.
3Productivity
If conductive terminals are assembled without a tenon structure, then the assembly process is faster, but the bonding strength between terminals and casing is insufficient
Solution Approach 1:
The tenon structure provides self-aligning and self-locking functionality during assembly. The geometric shape of the tenon and mortise structures guide the conductive terminals into proper positions and automatically secure them, reducing the need for additional assembly operations while ensuring strong bonding.
