PCB Connector With Movable Lock for Detachable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PCB connectors are either permanently attached, complicating recycling and causing manufacturing issues, or detachable connectors risk accidental detachment and alignment problems.
Innovation Solution
A connector design with a securing unit that moves between locking and release positions, using fastening arms and guide elements to ensure a secure, detachable connection to the PCB, allowing easy assembly and disassembly without damaging components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the PCB connector is permanently attached to the semiconductor board, then assembly is easy and alignment is precise, but recycling is complicated and component separation is difficult
Solution Approach 1:
The connector employs a dynamic locking mechanism with a securing unit that can transition between locked and unlocked states. The fastening arm with latching hook provides permanent-like stability when locked, while allowing complete separation when unlocked, thus enabling both easy assembly and recyclability.
Solution Approach 2:
The connector is designed as a separable component that can be completely detached from the semiconductor board. The locking mechanism divides the connection state into distinct locked and unlocked positions, allowing the connector to function as either a permanent or removable attachment depending on the application.
2Manufacturing precision
If the PCB connector is permanently attached to the semiconductor board, then alignment is precise, but component replacement is difficult
Solution Approach 1:
The dynamic locking mechanism allows the connector to maintain precise alignment when locked during operation, while enabling easy removal and replacement when unlocked. The fastening arm can be deflected to release the latching hook, facilitating component replacement without damaging the semiconductor board.
3Adaptability or versatility
If the PCB connector is detachably connected to the semiconductor board, then recycling is easy and component separation is simple, but accidental detachment can occur and alignment may be imprecise
Solution Approach 1:
The securing unit with movable locking mechanism provides a reliable locked position that prevents accidental detachment during normal operation. The latching hook engages with the semiconductor board to maintain stable connection, while still allowing intentional release when needed for recycling or replacement.
4Ease of repair
If the PCB connector is detachably connected to the semiconductor board, then component replacement is easy, but manufacturing tolerances cause movement and alignment problems
Solution Approach 1:
The connector incorporates preliminary alignment features that guide the connector into the correct position during attachment. The fastening arm and latching mechanism are designed to engage at predetermined positions that compensate for manufacturing tolerances, ensuring precise alignment even with detachable connection.
