Connector With Rotating Shield Shell And Integrated Mounting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors require a large number of parts to secure waterproof and shield properties, leading to increased size and reduced assembling efficiency, with the need for multiple bolts complicating size reduction and assembly.
Innovation Solution
A connector design featuring a cylindrical housing with an integral shield shell and mounting member, utilizing a fixing mechanism that includes a rotatable movable portion and tubular portion to eliminate the need for separate seal members and bolt fastening, allowing for reduced part count and size while maintaining waterproof and shield properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple seal members and a rear holder are used to secure waterproof property, then waterproof property is improved, but the number of parts increases and assembling efficiency deteriorates
Solution Approach 1:
The patent combines multiple seal members into a single integrated seal structure that simultaneously seals between the housing and wire, and between the housing and terminal. The rear holder function is merged with the housing structure itself, eliminating the need for a separate rear holder component. This merging reduces the number of parts while maintaining waterproof sealing effectiveness.
2Reliability
If a shield shell is fixed to the mounting member through multiple bolts, then shield property is improved, but the number of parts increases, size increases, and assembling efficiency deteriorates
Solution Approach 1:
The shield shell is integrated with the housing structure, forming a unified component that provides both mechanical support and electromagnetic shielding. The mounting member is designed with built-in fixing features that eliminate the need for separate bolts, directly fixing the shield shell to the housing through the integrated structure.
Solution Approach 2:
The patent removes the bolts from the assembly, extracting the fastening function and integrating it directly into the housing and mounting member structures. This eliminates the need for separate fastening components while maintaining the shield shell's secure attachment.
3Strength
If multiple bolts are used to fix the shield shell, then fixing strength is improved, but size increases and assembling efficiency deteriorates
Solution Approach 1:
The patent removes bolts entirely from the design, extracting the fastening function and embedding it within the housing and mounting member structures. This eliminates the need for tool-based fastening operations while maintaining adequate fixing strength through the integrated structural design.
Solution Approach 2:
The housing and mounting member are designed with self-fixing features that automatically secure the shield shell during assembly without requiring external fastening tools or operations. The structure itself provides the fixing mechanism, enabling tool-free assembly.
4Strength
If multiple bolts and fastening tools are used, then fixing strength is improved, but assembling efficiency deteriorates
Solution Approach 1:
The mounting member and housing are designed with self-fixing features that automatically secure the shield shell during assembly without requiring external fastening tools or operations. The structure itself provides the fixing mechanism, enabling tool-free assembly while maintaining adequate fixing strength.

AI summary
A connector includes a cylindrical-shaped housing inserting therein a wire, a shield shell disposed on an outer side of the housing, and a mounting member assembled with the housing and the shield shell. The mounting member includes a tubular portion inserted into a gap between the housing and the shield shell in a diameter direction of the housing and contacted with an end face of the housing. The shield shell includes a fixing portion fixed to the housing and a movable portion rotatably connected to the fixing portion. A fixing mechanism is provided between the movable portion and the tubular portion, moves the end face toward the tubular portion when the movable portion is rotated, and fixes the housing and the shield shell to the mounting member when the tubular portion and the end face closely contacted with each other.
