Grounding Collar Integrated with Shielding Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face difficulties in achieving reliable mechanical and electrical connections between the grounding collar and the shielding plate, particularly during the insert-molding process, as seen in prior art such as Chinese patent applications CN205355339 and CN204835065.
Innovation Solution
The electrical connector design includes an insulative housing with a tongue portion and a rear step section, featuring terminals with exposed contacting sections, retaining sections, and soldering sections, along with a metallic shielding plate and a grounding plate that is mechanically and electrically connected to the grounding terminals and shielding plate through coupling parts and lateral extensions, ensuring secure assembly via insert-molding and overmolding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grounding collar is soldered to the shielding plate, then the electrical connection is achieved, but the assembly process becomes complex and difficult to manufacture
Solution Approach 1:
The grounding collar is integrated with the shielding plate to form a unitary structure, combining two separate components into one. This eliminates the need for separate soldering operations and simplifies the assembly process while maintaining reliable electrical connection between the grounding collar and shielding plate.
Solution Approach 2:
The grounding collar and shielding plate are pre-assembled into a unified structure before the final connector assembly process. This preliminary integration ensures the electrical connection is established in advance, reducing manufacturing steps and improving ease of assembly.
2Ease of manufacture
If the grounding collar is unitarily formed with the shielding plate, then the manufacturing process is simplified, but the mechanical connection strength may be compromised
Solution Approach 1:
The grounding collar and shielding plate are formed as a single unitary structure, merging two components into one integrated piece. This approach simplifies manufacturing by eliminating separate assembly steps while the integrated design ensures adequate mechanical strength through the unified structure.
3Adaptability or versatility
If separate grounding terminals are used, then the connector design is flexible, but the assembly process becomes more difficult
Solution Approach 1:
Multiple grounding terminals are integrated into the shielding plate structure, combining several functional elements into one component. This maintains design flexibility for multiple grounding points while simplifying assembly by reducing the number of separate parts that need to be handled and positioned.

AI summary
An electrical connector assembly includes an insulative housing, a plurality of terminals retained in the housing, and a metallic shielding plate embedded within the housing. The insulative housing includes a base and a tongue portion extending forwardly from the base. The tongue portion includes a mating section and a rear step section. There are two rows of terminals. The shielding plate is disposed between the two rows of terminals. The terminals include a pair of outermost grounding terminals in a transverse direction. A grounding plate positioned upon the rear step section, is mechanically and electrically connected to at least one of the corresponding grounding terminal and the shielding plate wherein the corresponding grounding terminal and the shielding plate have corresponding extension soldered to the grounding plate.
