Shielding Plate Side Hooks Stabilize Grounding Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in reliably securing and positioning the grounding legs of the shielding shell, which affects the stability and accuracy of subsequent soldering operations on printed circuit boards.
Innovation Solution
The use of a shielding plate with side hooks that securely engage and latch the grounding legs of the shielding shell, preventing displacement and ensuring proper positioning for soldering, involves an insulative housing with a base and tongue structure, and a shielding shell with specific recesses and protrusions for stable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grounding legs are secured by the insulative housing alone, then the structure is simple, but the positioning stability and reliability of grounding legs are insufficient
Solution Approach 1:
The shielding plate serves as an intermediary component between the insulative housing and the grounding legs. The side hooks on the shielding plate engage with the grounding legs to provide additional positioning stability, while the insulative housing provides overall support. This intermediary structure resolves the contradiction by enhancing reliability without requiring complete redesign of the housing structure.
Solution Approach 2:
The positioning function is segmented between two components: the insulative housing provides basic support and enclosure, while the shielding plate with side hooks provides precise positioning and stabilization of the grounding legs. This segmentation allows each component to specialize in its function, improving overall reliability without significantly increasing complexity.
2Manufacturing precision
If grounding legs are not properly positioned, then assembly is simple, but soldering accuracy and operational reliability deteriorate
Solution Approach 1:
The shielding plate with side hooks is designed to preliminarily position and stabilize the grounding legs before the soldering process. This preliminary positioning action ensures that the grounding legs are correctly aligned and secured, improving soldering accuracy without complicating the overall assembly process.
Solution Approach 2:
The shielding plate acts as a mediator that translates the simple assembly structure into precise positioning. The side hooks engage with the grounding legs to provide the necessary alignment and stability, enabling accurate soldering while maintaining ease of assembly through the modular design.

AI summary
An electrical connector includes: an insulative housing having a base and a tongue; an upper and a lower rows of contacts secured to the insulative housing and exposed, respectively, to an upper and a lower faces of the tongue; a shielding plate arranged between the upper row of contacts and the lower row of contacts; and a shielding shell enclosing the insulative housing, wherein the shielding plate has a pair of side hooks exposed to an outside of the insulative housing, and the shielding shell has a pair of grounding legs kept in position by the pair of side hooks of the shielding plate.
