Compact Connector Shield Overlap Guide Face
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with shield members face challenges in guiding connections while maintaining a compact size, as the placement of reinforcing metal fittings and shield plates often necessitate increased housing length to accommodate these components.
Innovation Solution
The connector design incorporates a shield member with overlapping coupling and guide faces, and an auxiliary shield portion that suppresses electromagnetic wave propagation, allowing for efficient connection guidance without increasing the housing size by eliminating the need for offsetting the coupling portion and integrating the auxiliary shield within the existing structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the coupling portion is disposed to overlap the guide face, then the housing length is reduced, but the guiding function and electromagnetic wave suppression may be compromised
Solution Approach 1:
The coupling portion and guide face are merged in the longitudinal direction, allowing the coupling portion to overlap the guide face. This integration eliminates the need for separate offset spaces, reducing housing length while maintaining both the guiding function and electromagnetic wave suppression capability through coordinated design of these components.
Solution Approach 2:
The shield portions extend in the width direction (transverse to the longitudinal axis) to provide electromagnetic wave suppression, while the coupling portion overlaps the guide face in the longitudinal direction. This multi-dimensional arrangement allows functional components to coexist without increasing housing length in the primary direction.
2Reliability
If the outer side connection portions are disposed further toward outer sides from the guide face, then the guide face is not covered, but the housing size increases
Solution Approach 1:
The coupling portion is merged with the guide face in the longitudinal direction, allowing both components to occupy the same longitudinal space. This eliminates the need to offset the coupling portion outward, preventing housing length increase while maintaining the guide face's guiding function through proper structural design.

Function Achieved in This Case
This design effectively guides connections while preventing an increase in housing size, enhances electromagnetic wave suppression, and restricts auxiliary shield displacement, ensuring secure and compact connector configurations.
Implementation Method 1
The pair of shield portions are disposed on both sides of the housing in a first direction intersecting the insertion-removal direction so as to suppress propagation of electromagnetic waves

AI summary
A connector includes a housing and a shield member. The housing includes an insertion-removal section and a guide face, a connection target is inserted into or removed from the insertion-removal section through an insertion-removal port in an insertion-removal direction, and the guide face is formed at a peripheral portion of the insertion-removal section so as to guide the connection target toward the insertion-removal section. The shield member includes a pair of shield portions and a coupling portion. The pair of shield portions are disposed on both sides of the housing in a first direction intersecting the insertion-removal direction, the coupling portion couples the pair of shield portions together in the first direction, the coupling portion contacts a location of the housing on an opposite side to the insertion-removal port in the insertion-removal direction, and the coupling portion at least partially overlaps the guide face as viewed in the insertion-removal direction.
