Electrical Connector Shielding Shell Soldering Leg Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in securely fastening and grounding contacts within a shielding shell while maintaining waterproof integrity, as they often lack effective mechanisms to prevent soldering legs from moving outward and ensuring reliable contact with the printed circuit board.
Innovation Solution
The design incorporates a contact module with an insulative housing featuring side latching walls and a shielding shell with side arms that have soldering legs, where the inserting portions of the side arms engage the latching walls to prevent outward movement, combined with an insulative outer cover and brackets insert-molded with the outer cover for enhanced sealing and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the insulative housing has side latching walls, then the shielding shell is securely fastened, but the structure complexity increases
Solution Approach 1:
The side latching walls are integrated directly into the insulative housing structure, merging the fastening function with the housing itself. This eliminates the need for separate fastening components, achieving strong attachment between the shielding shell and housing while maintaining structural simplicity.
Solution Approach 2:
The side latching walls serve multiple functions: they provide structural support for the housing, enable secure fastening of the shielding shell, and maintain precise positioning of the soldering legs. This multi-functionality reduces the need for additional specialized components.

AI summary
An electrical connector includes: a contact module including an insulative housing and an upper and lower rows of contacts, the insulative housing having a rear base and a front tongue, the base having a pair of side latching walls; and a shielding shell enclosing the contact module, the shielding shell having a main part and a pair of side arms extending rearwardly from the main part, each side arm having an inserting portion and a soldering leg; wherein each inserting piece engages a corresponding side latching wall to prevent an associated soldering leg from moving outwardly.
