Shield Connector With Deformable Locking Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of two types of shield connectors, one for collective shielding and one for individual shielding, requires managing two sets of connector housings and shield shells, leading to inefficiencies in component management.
Innovation Solution
A common connector housing is used for both collective and individual core shield shells, with resilient locking pieces that can deform intersectingly with the bolt tightening direction, allowing for tolerance absorption and maintaining engagement margins, thus reducing the number of components and improving locking force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two types of shield connectors (collective and individual core) are used separately, then each connector can be optimized for its specific shielding function, but the number of components increases and parts management becomes inefficient
Solution Approach 1:
The connector housing is designed with a universal structure that can accommodate both collective shield shells and individual core shield shells. The housing includes a through hole and resilient locking pieces that work with both types of shield shells through different engaging portions, allowing one housing design to serve multiple shielding configurations.
2Device complexity
If the resilient locking piece deforms in the same direction as bolt tightening, then the locking mechanism is simple, but manufacturing and assembly tolerances reduce the engagement margin and locking force
Solution Approach 1:
The resilient locking piece is designed to deform in a direction perpendicular to the bolt tightening direction. The locking piece extends in the width direction and deforms in the width direction, while the bolt tightens in the front-back direction. This dimensional separation ensures that tolerances in one direction do not affect the engagement margin in another direction, maintaining reliable locking 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
This configuration reduces the number of components needed, enhances parts management, and maintains effective locking force even with manufacturing and assembly tolerances, by allowing the resilient locking pieces to deform in a direction different from the bolt tightening, thereby absorbing stress and maintaining engagement.
Implementation Method 1
a resilient locking piece which is resiliently deformable in a direction intersecting with the tightening direction of the bolt

AI summary
A shield connector (10) includes a connector housing (20) with resiliently deformably provided resilient locking pieces (25), a collective shield shell (50) formed with collective side engaging portions (56) engageable with the resilient locking pieces (25), and an individual core shield shell (30) formed with individual-core side engaging portions (38) engageable with the resilient locking pieces (25). Either one of the collective and individual core shield shells (50, 30) is selectively fixed to the connector housing (20) by engaging the resilient locking pieces (25) and the collective side engaging portions (56) when the collective shield shell (50) is mounted onto the connector housing (20) or engaging the resilient locking pieces (25) and the individual-core side engaging portions (38) when the individual core shield shell (3) is mounted onto the connector housing (20).
