Direct PCB Cable Plug Contact to Reduce Signal Attenuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting cables to circuit boards result in signal strength loss due to attenuation, which worsens with increasing signal frequency and transmission volume, especially in applications like 5G communications, artificial intelligence, and Internet of things devices.
Innovation Solution
An anti-attenuation apparatus that secures a male connector directly onto a circuit board using a securing assembly with elastic terminals, eliminating the need for a pre-soldered board end connector, thereby reducing the number of junctions and minimizing signal attenuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a board end connector is used to connect the cable to the circuit board, then the connection is established, but signal attenuation increases due to multiple junctions
Solution Approach 1:
The patent extracts and removes the board end connector from the connection system, allowing the male connector to contact the circuit board directly. This eliminates the intermediate connector that causes signal attenuation, reducing the number of junctions from multiple to minimal while maintaining reliable electrical connection.
2Stability of the object's composition
If a board end connector is used to secure the cable, then the connection is stable, but the device complexity increases
Solution Approach 1:
The patent merges the functions of the board end connector and the male connector into a single direct contact interface. The male connector's elastic terminals directly engage with the circuit board's connecting pads, combining what were previously separate components (board end connector and cable connector) into a simplified unified connection structure.
3Adaptability or versatility
If multiple junctions are used between cable and circuit board, then connection flexibility is maintained, but manufacturing precision requirements increase
Solution Approach 1:
The patent removes the board end connector that created multiple junctions requiring precise alignment. The direct contact between the male connector's elastic terminals and the circuit board's connecting pads reduces alignment complexity while maintaining connection flexibility through the elastic deformation capability of the terminals.

Function Achieved in This Case
This approach enhances signal transmission stability by decreasing the number of junctions between the cable and the circuit board, improving high-frequency signal quality and reducing signal loss.
Implementation Method 1
the elastic terminal will be bent and be pressed onto the connecting pad of the circuit board

AI summary
An anti-attenuation apparatus has an electronic device and a cable assembly. The electronic device has a circuit board and a plurality of metal pads mounted on the circuit board as female connecting spots. The cable assembly has a cable main body and an inserting connector. The inserting connector is mounted at an end of the cable main body and has multiple elastic components as male connecting spots. The female connecting spots and the male connecting spots selectively contact each other and thus the electric connection is formed. Therefore, the electronic device needs no additional socket and no additional connector as female connecting spots. Similarly, the cable assembly needs no additional connector for connecting the elastic component and the cable main body. In other words, twice attenuations are skipped in a set that has the electronic device and the cable assembly.
