Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in achieving reliable grounding and secure mounting of contacts to a printed circuit board due to the limitations in the design of the soldering legs and grounding tails, which can lead to instability and inefficiency in electrical connections.
Innovation Solution
The electrical connector design features a grounding plate with side tails exposed outside the insulative housing and soldering legs that upwardly abut these tails, creating a positive retention and reliable contact mechanism, ensuring effective grounding without hindering the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the soldering legs and grounding tails are designed with conventional configurations, then the assembly process is simple, but the electrical connection stability and grounding reliability are insufficient
Solution Approach 1:
The soldering legs are extended upward from the shielding shell to abut against the grounding plate, adding a vertical dimension to the connection. This upward extension creates a three-dimensional abutment structure that enhances contact stability and grounding reliability without significantly complicating the overall design.
Solution Approach 2:
The abutment structure serves as an intermediary mechanism between the shielding shell and the grounding plate. By introducing this intermediate abutment feature, the patent achieves more reliable electrical connection and grounding without requiring direct complex integration between the shell and plate.
2Reliability
If the soldering legs are extended upward to abut the grounding plate, then the grounding reliability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The soldering legs are integrated directly into the shielding shell structure, merging two components into one. This integration eliminates the need for separate fabrication and assembly of the soldering legs, simplifying the manufacturing process while maintaining the upward abutment function for reliable grounding.
3Reliability
If the side tails of the grounding plate are exposed outside the insulative housing, then the contact with soldering legs is improved, but the structural complexity increases
Solution Approach 1:
The grounding plate is segmented into distinct functional zones: the main grounding area between the contact rows and the exposed side tails that extend outward. This segmentation allows the side tails to be specifically optimized for contacting the soldering legs while the main plate provides grounding, creating a clear functional division that improves contact reliability without excessive complexity.

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 two opposite faces of the tongue; a grounding plate arranged between the upper row of contacts and the lower row of contacts; and a shielding shell enclosing the insulative housing, wherein the grounding plate has a pair of side tails exposed to an outside of the insulative housing, and the shielding shell has a pair of soldering legs upwardly abutting the pair of side tails of the grounding plate.
