Antenna Connector Dynamic Connection for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication terminals, the frequent deformation of cables connecting antennas and printed circuit boards (PCBs) due to mechanical stress leads to damage and line loss, degrading antenna performance.
Innovation Solution
An antenna connector system that automatically connects and disconnects the antenna and PCB based on the movement of the terminal's members, using a mechanism with curved rails, connection members, and elastic projections to manage cable stress and maintain electrical connection only when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connects the antenna and PCB continuously, then electrical connection is maintained, but cable deformation and damage occur due to frequent movement
Solution Approach 1:
The patent implements a dynamic connection system where the cable connection between antenna and PCB is automatically established or disconnected based on the movement state of the terminal. When the terminal body moves relative to the antenna, the connection is disconnected to prevent cable deformation, while maintaining connection when stationary for normal operation.
Solution Approach 2:
The system automatically detects its own movement state and self-regulates the cable connection status without external intervention. The terminal body's movement triggers automatic disconnection, and returning to original position triggers automatic reconnection, eliminating the need for manual cable management.
2Adaptability or versatility
If the cable is frequently deformed due to movement, then connection flexibility is maintained, but line loss increases and antenna performance degrades
Solution Approach 1:
The system dynamically adjusts cable connection status based on movement detection. During terminal body movement, the cable connection is automatically disconnected to prevent deformation-induced signal loss. When the terminal returns to its original position, the connection is automatically reestablished, ensuring signal quality is maintained while preserving movement flexibility.
3Reliability
If the cable remains connected during movement, then continuous electrical connection is maintained, but mechanical stress damages the cable
Solution Approach 1:
The patent employs dynamic connection control where the electrical connection between antenna and PCB is automatically disconnected when the terminal body moves relative to the antenna, preventing mechanical stress accumulation. The connection is automatically reestablished when the terminal returns to its original position, maintaining both connection stability and cable strength.
Solution Approach 2:
The system proactively disconnects the cable connection before excessive mechanical stress can accumulate during terminal movement. By detecting movement in advance and disconnecting the cable, the system prevents damage before it occurs, then automatically reconnections when movement ceases.

Function Achieved in This Case
Reduces cable deformation and line losses by ensuring the antenna and PCB are only electrically connected during active use, enhancing antenna performance and durability.
Implementation Method 1
an elastic projection extending along the moving direction of the connection member at one end of the connection member, and a groove into which the elastic projection is inserted when the connection member is viewed from a side in the moving direction

AI summary
A mobile communication terminal includes a main member and a moving member movably joined to the main member. An antenna connector connects and disconnects an antenna to a PCB according to a movement of the moving member. The antenna connector includes: a rail provided in one of the second member and the first member; a connection member moveable along the rail, the connection member being electrically conductive; and a holder to support the connection member on the rail and to which a first cable extending from one of the antenna and the PCB is connected; and a terminal, disposed adjacent to the rail, of a second cable extending from the other of the antenna and the PCB.
