Shield Connector Structure for Continuous Receptacle Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shield connectors suffer from reduced shielding performance due to noise leakage at the boundary between the rear end edge of the receptacle and the front wall portion, caused by cuts formed during the bending process of the outer conductor.
Innovation Solution
A shield connector design featuring a dielectric with an outer conductor made of a metal plate material, including a box-shaped body portion and a receptacle projecting forward from the front wall, where the rear end part of the receptacle and the front wall are continually and electrically conductively connected, minimizing noise leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer conductor is formed by bending a metal plate material into L-shaped fitting and board mounting portions, then the manufacturing cost is reduced compared to die casting, but cuts are inevitably formed at the boundary between portions which reduces shielding performance
Solution Approach 1:
The outer conductor is divided into multiple plate portions (first side plate portion, second side plate portion, lower plate portion, front plate portion) that are bent and assembled together. This segmentation allows each portion to be formed separately and then joined, maintaining the low-cost bending process while enabling continuous conductive connection through overlapping joints that eliminate gaps at boundaries.
Solution Approach 2:
Multiple plate portions are merged through overlapping and joining to form a continuous conductive structure. The first side plate portion and second side plate portion overlap with the lower plate portion and front plate portion respectively, creating continuous conductive paths that eliminate gaps while maintaining the bent plate construction method.
2Shape
If cuts are formed at the boundary between the rear end edge of the lower plate portion and the upper end edge of the front plate portion during bending, then the L-shaped structure can be formed, but noise leakage occurs which reduces shielding performance
Solution Approach 1:
Overlapping joints are designed in advance at the boundaries between plate portions. The first side plate portion and second side plate portion are positioned to overlap with the lower plate portion and front plate portion respectively before final assembly, ensuring continuous conductive connection that prevents noise leakage at boundaries while maintaining the L-shaped configuration.
Solution Approach 2:
The overlapping portions of the metal plate structure act as intermediaries that bridge the boundaries between different plate sections. These overlapping regions provide continuous conductive paths that eliminate gaps and prevent noise leakage, while allowing the overall L-shaped structure to be maintained.

AI summary
It is aimed to realize an improvement in shielding performance. A shield connector is provided with a dielectric for accommodating an inner conductor and an outer conductor made of a metal plate material and surrounding the dielectric. The outer conductor includes a box-shaped body portion and a receptacle projecting forward from a front wall portion of the body portion, a mating outer conductor being fit into the receptacle. A rear end part of the receptacle and the front wall portion are continually and electrically conductively connected.
