Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors fail to establish a secure connection between the CPU and the printed circuit board due to insufficient loading force, leading to ineffective electromagnetic interference shielding and poor electrical connectivity.
Innovation Solution
An electrical connector assembly featuring an insulative housing with a load plate and a metallic shielding device that provides additional loading force, comprising a shield device with an upper section and side sections forming a closed space to house the connector and mitigate EMI, along with a thermal pad for heat dissipation and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a traditional latch mechanism is used to engage the electrical connector, then the structure is simple, but the loading force provided to the CPU is insufficient
Solution Approach 1:
The patent combines the shielding device with the loading force application mechanism. The shielding device includes a load plate that directly contacts and applies loading force to the CPU, merging the shielding function with the mechanical engagement function into a single integrated component structure.
Solution Approach 2:
The shielding device serves multiple functions: it provides electromagnetic shielding, applies loading force to the CPU, and maintains electrical connection stability. This multi-functional design eliminates the need for separate latch mechanisms, resolving the contradiction between simplicity and sufficient loading force.
2Object-affected harmful factors
If the electrical connector is exposed without shielding, then the structure is simple, but electromagnetic interference affects signal quality
Solution Approach 1:
The patent merges the shielding function with the mechanical support function by integrating the shielding walls into the connector housing structure. The shielding device forms an enclosed space that simultaneously provides EMI protection and structural support for the electrical connections.
Solution Approach 2:
The electrical connector is nested within the shielding device, which includes side sections and a load plate forming an enclosed space. This nested configuration provides EMI shielding while maintaining a compact overall structure, resolving the contradiction between shielding effectiveness and structural simplicity.
3Reliability
If insufficient loading force is applied to the CPU, then the connector structure is simple, but poor electrical connection results
Solution Approach 1:
The load plate of the shielding device is directly engaged with the CPU to apply loading force, merging the shielding structure with the mechanical engagement mechanism. This ensures reliable electrical connection through sufficient loading force while maintaining structural integration.
Solution Approach 2:
The shielding device simultaneously provides EMI shielding, structural support, and mechanical engagement with adequate loading force. This multi-functional approach ensures reliable electrical connection without requiring additional complex latch mechanisms.
