Integrated Wire Holder Connector for Compact Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors, such as U-shaped connectors, face challenges in miniaturization while maintaining vibration resistance, as the inclusion of an electric wire holder to manage wires orthogonal to the terminal direction can increase the connector's size.
Innovation Solution
A connector design that incorporates an electric wire lead-out portion with an integrated electric wire holder, allowing the electric wires to be led out in the same direction as the connector's connection to an external connector, thereby avoiding the need for an additional wire holder that would increase the connector's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electric wire holder for holding a part of an electric wire extending in the orthogonal direction is provided inside a U-shaped connector, then vibration resistance is improved, but the connector size increases
Solution Approach 1:
The electric wire holder is integrated into the terminal structure, merging two previously separate components (terminal and wire holder) into a single unified structure. This integration eliminates the need for additional space for a separate wire holder while still providing the necessary wire holding function, thus improving vibration resistance without increasing connector size
Solution Approach 2:
The invention changes the orientation of the electric wire lead-out direction from orthogonal to parallel with the terminal direction. This dimensional change allows the wire holder to be incorporated within the existing terminal structure rather than requiring additional external space, resolving the contradiction between vibration resistance and compact size
2Reliability
If the electric wire lead-out direction is made orthogonal to the terminal direction (L-shaped connector), then vibration resistance is improved, but the connector complexity increases
Solution Approach 1:
The terminal structure is designed to serve multiple functions: it provides electrical connection and simultaneously acts as the electric wire holder. This multi-functionality eliminates the need for separate wire holding components, reducing structural complexity while maintaining vibration resistance
Solution Approach 2:
Instead of making the wire lead-out direction orthogonal to the terminal direction (L-shaped), the invention inverts this approach by making the wire lead-out direction parallel to the terminal direction (U-shaped), which simplifies the overall connector structure while still achieving vibration resistance through the integrated wire holder design

AI summary
A connector connected to an external connector has a plurality of terminals and an electric wire lead-out portion for leading out a plurality of electric wires connected to each of the terminals to the outside in a first direction of connection to the external connector, and the electric wire lead-out portion has an electric wire holder which holds each of the electric wires by clamping.
