Electrical Connector Protective Cover for PCB Terminal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a test circuit board onto a coaxial electrical connector can easily damage the mating terminal due to direct contact, which is a common issue in existing connectors.
Innovation Solution
An electrical connector design featuring a protective cover that is removably sleeved on the mount portions and fasteners, forming an installation slot between the cover and the clamp component, allowing the circuit board to be inserted without hitting the terminal, and incorporating a light permeable structure for accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the circuit board is directly installed onto the coaxial electrical connector, then the installation process is simple and quick, but the circuit board may hit and damage the mating terminal of the connector
Solution Approach 1:
The patent introduces a protective cover as an intermediary component between the circuit board and the mating terminal. This cover includes an installation slot that guides the circuit board during installation, allowing the board to be inserted without directly contacting the vulnerable terminal. The protective cover thus mediates the interaction between the circuit board and terminal, enabling fast installation while preventing damage.
Solution Approach 2:
The protective cover is pre-installed on the coaxial electrical connector before the circuit board installation. This preliminary action positions the installation slot in advance, creating a guided pathway that prevents the circuit board from hitting the terminal during the subsequent installation process. The protective cover is later removed after installation completes its protective function.
2Reliability
If a protective structure is added to prevent circuit board from hitting the terminal, then the terminal is protected from damage, but the device complexity increases
Solution Approach 1:
The protective cover is designed as a separate, removable component rather than an integrated part of the connector body. This segmentation allows the protective function to be added without permanently complicating the connector structure. The cover can be easily attached and removed, maintaining simplicity in the base connector design while providing protection when needed.
Solution Approach 2:
The protective cover is designed as a thin-walled structure with an installation slot, providing protection through its presence rather than through robust material properties. This thin-film approach minimizes the added complexity and material usage while still effectively preventing the circuit board from contacting the terminal.

AI summary
An electrical connector includes a seat body, a signal joint, a clamp component, a fastener and a protective cover. The seat body includes a main portion and a mount portion. The signal joint is fixed to the main portion and has a terminal. The clamp component is movably disposed on the main portion. The terminal is located at one side of the mount portion located closer to the clamp component. The fastener is disposed on the mount portion. The protective cover, has a recess. The protective cover is removably sleeved on the mount portion and the fastener, the protective cover is partially located between the mount portion and the clamp component, the terminal is located in the recess, an installation slot is formed between the protective cover and the clamp component for the circuit board to be inserted into for aligning the circuit board with the terminal.
