Integrated Female Connector Rear Cover for EMI Shielding Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing female connectors require multiple metal sheets for effective electromagnetic wave interference prevention and stabilization, leading to increased costs and redundant components, as well as potential shaking or retreat of internal components during connector docking.
Innovation Solution
A two-stage rear cover structure with a core body, terminals, and a one-piece shielding shell featuring a step-shaped stopper portion, positioning portion, and a rear cover portion with folded portions and Z-shaped buckle blocks, which integrates the shielding shell to prevent electromagnetic interference and stabilize the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple metal sheets are assembled to prevent electromagnetic wave interference and stabilize the connector, then the shielding effect and stability are improved, but the component quantity and assembly complexity increase
Solution Approach 1:
The patent combines multiple separate metal sheets into a single integrated shielding shell with a unified structure. The shielding shell includes a shell body, rear cover portion, and fixing portion that work together as one piece to provide electromagnetic shielding and stabilization, eliminating the need for multiple separate metal sheets and reducing assembly complexity.
Solution Approach 2:
The integrated shielding shell performs multiple functions simultaneously: it provides electromagnetic wave shielding through its conductive structure, stabilizes the connector through the fixing portion that prevents retreat and shaking, and serves as a structural housing. This multi-functional design replaces the need for separate shielding sheets and stabilization components.
2Reliability
If multiple metal sheets are assembled to prevent electromagnetic wave interference and stabilize the connector, then the shielding effect and stability are improved, but the assembly cost and time increase
Solution Approach 1:
By integrating the shielding shell as a single piece that incorporates both electromagnetic shielding functionality and mechanical stabilization features, the patent reduces the number of assembly steps. The fixing portion with its specific structure can be installed in one operation rather than requiring multiple separate metal sheets to be assembled and secured individually.
3Object-affected harmful factors
If multiple metal sheets are used to cover the connector, then electromagnetic wave interference is prevented, but redundant components and space waste occur
Solution Approach 1:
The patent merges multiple separate metal sheets into a single integrated shielding shell structure. This unified design provides complete electromagnetic shielding coverage while eliminating redundant components. The shielding shell is precisely shaped to fit the connector assembly, avoiding excess material and reducing component count.

AI summary
A two-stage rear cover structure of integrated female connector includes a core body, terminals and a shielding shell. The terminals each have a butt end extending in one respective slit of a tongue portion of the core body, and a soldering end extending out of a positioning portion of the core body. The shielding shell has a shell body covering the core body, a rear cover portion attached to a step-shaped stopper portion of the core body, and a fixing portion accommodating the positioning portion of the core body. The above-mentioned components are used to avoid the interference of the electromagnetic wave of the external parts to the connector and prevent the connector from retreating and shaking when it is docked. It saves additional assembly cost and time with the integrated shielding shell.
