Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a simple fastening method for both unshielded and shielded plug connectors on printed circuit boards using the same arrangement of solder points, as existing solutions require separate solder points for strain relief brackets and shielding plates.
Innovation Solution
A plug connector design that includes a housing with a fastening mechanism and a shielding or retaining plate, where the retaining plate is connected to the same solder points as the shielding plate, allowing for secure fastening to the printed circuit board without the need for additional solder points, and can be used interchangeably with shielding plates to maintain electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate solder points are used for strain relief brackets and shielding plates, then unshielded and shielded plug connectors can be fastened securely, but the complexity of the solder point arrangement increases and manufacturing becomes more complicated
Solution Approach 1:
The patent applies universality by designing a retaining plate that serves multiple functions: it acts as both a strain relief bracket for unshielded connectors and a mounting structure for shielded connectors. The same retaining plate and solder point arrangement are used in both shielded and unshielded versions, eliminating the need for separate fastening mechanisms and simplifying the solder point layout while maintaining secure fastening for both connector types.
2Reliability
If strain relief brackets are used for unshielded plug connectors, then secure fastening is achieved, but additional solder points are required beyond those for the connector itself
Solution Approach 1:
The patent merges the function of the strain relief bracket with the shielding plate structure. The retaining plate is integrated into the connector assembly such that it uses the same solder points as the connector contacts. This combining of functions eliminates the need for separate solder points for strain relief, reducing the total quantity of solder points required while maintaining secure fastening.
3Object-affected harmful factors
If shielding plates are used for shielded plug connectors, then electromagnetic shielding is provided, but the fastening mechanism becomes more complex compared to unshielded connectors
Solution Approach 1:
The patent applies universality by creating a fastening mechanism that is identical for both shielded and unshielded connectors. The retaining plate and its connection method to the printed circuit board are the same regardless of whether a shielding plate is present. This universal fastening approach simplifies the overall mechanism while still providing secure mounting for shielded connectors that require electromagnetic shielding.
