Metal Wire-Holding Bracket for High-Temperature Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with resin rear holders deform under high-temperature environments, allowing clearance formation and ineffective suppression of wire swing, leading to connection failures.
Innovation Solution
A connector design featuring a metal bracket with first and second holding portions that sandwich and fix the wire perpendicularly, including a fixing portion to the connector housing, to suppress wire swing and distribute external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin rear holder is used to hold the wire, then the wire swing can be suppressed under normal conditions, but the rear holder deforms by creep under high-temperature environments, forming clearance and failing to suppress wire swing
Solution Approach 1:
The material of the rear holder is changed from resin to metal, fundamentally altering the physical and mechanical parameters of the component. This material substitution eliminates creep deformation under high-temperature conditions while maintaining the wire swing suppression function, directly resolving the contradiction between reliability and structural stability.
2Stability of the object's composition
If the rear holder is made of metal to prevent deformation, then structural stability is improved, but the complexity of the connector structure increases
Solution Approach 1:
The metal rear holder is designed to perform multiple functions: it suppresses wire swing, resists high-temperature deformation, and provides structural support for the terminal. By integrating these functions into a single component, the design avoids additional parts while achieving the desired structural stability, thus resolving the contradiction between stability and complexity.
3Ease of manufacture
If the bracket structure is simplified to reduce manufacturing complexity, then ease of manufacture is improved, but the ability to suppress wire swing and distribute external forces is reduced
Solution Approach 1:
The rear holder is segmented into distinct functional regions: a wire holding portion with specific geometry to suppress wire swing, a terminal holding portion to support the terminal, and an integration portion to connect with the connector housing. This segmentation allows each region to be optimized for its specific function while maintaining overall structural simplicity and ease of manufacture.

AI summary
A connector 10 is provided with a connector housing 15 including a wire draw-out opening 20, a terminal 14 accommodated in the connector housing 15, a wire 12 connected to the terminal 14 and pulled out to outside of the connector housing 15 through the wire draw-out opening 20, and a bracket 22 made of metal for holding the wire 12 pulled out through the wire draw-out opening 20. The bracket 22 includes a first holding portion 24 and a second holding portion 26 to be fixed to each other while sandwiching and holding the wire 12 from both sides in a direction perpendicular to an axis of the wire 12, and a fixing portion 139 to the connector housing 15.
