Power Interface Antenna Interference via Intermediate Patch Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power interfaces in mobile devices often interfere with antenna signals, leading to reduced signal quality and transmission speed, and lack reliability in connections between components.
Innovation Solution
The power interface design includes spacing the tail end of the intermediate patch from the connection housing and connecting it to the connection body, ensuring reliable connections among the intermediate patch, connection housing, and connection body, thus avoiding interference with antenna signals and improving signal transmission quality and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power interface components are closely integrated to improve connection reliability, then the connection reliability is improved, but the antenna signal interference increases
Solution Approach 1:
The power interface structure is divided into separate functional components: connection housing, connection body, and intermediate patch. The intermediate patch acts as a spatial separator that divides the signal transmission path, allowing power signals to be transmitted through the connection body while antenna signals pass through the intermediate patch region, thereby preventing interference between the two signal types while maintaining reliable connections.
2Object-affected harmful factors
If the intermediate patch is spaced from the connection housing to reduce signal interference, then the antenna signal quality is improved, but the connection reliability may be compromised
Solution Approach 1:
The intermediate patch serves as an intermediary element between the connection housing and the connection body. It provides both electrical connection and physical spacing, acting as a mediator that maintains reliable electrical connectivity while creating the necessary spatial separation to prevent antenna signal interference. The intermediate patch thus resolves the contradiction by being both a connector and a separator simultaneously.

AI summary
A power interface (100), a mobile terminal, and a power adapter are disclosed. The power interface (100) includes a connection housing (1), a connection body (2), and an intermediate patch (23). The connection body (2) is arranged in the connection housing (1), configured to be connected to a circuit board (25), and includes at least a pair of power pins (21). Each pair of power pins (21) includes a pair of sub-pins (211) spaced apart from each other in an up-down direction. The intermediate patch (23) is sandwiched between the pair of sub-pins (211), and includes a head end close to a front end of each power pin (21) and a tail end close to a rear end of each power pin (211). The tail end is spaced apart from the connection housing (1) and connected to the connection body (2).
