Sliding Locking Circuit Board Assembly for Easy Server Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and maintenance of servers are cumbersome due to the need for multiple fastening components, and the close engagement of circuit boards makes plugging or unplugging connectors difficult, especially in modularized cases.
Innovation Solution
A circuit board with a locking structure featuring a locking assembly that includes an operating portion and a locking rod, allowing the locking rod to slide between locked and released positions, reducing the need for additional locking components and facilitating easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastening components such as screws are used to fix expandable components on the chassis, then the fixing reliability is improved, but the assembling process becomes cumbersome and the number of components increases
Solution Approach 1:
The patent combines the fastening function and locking function into a single integrated locking component. This locking component has a locking body that can be inserted into a locking hole to secure the circuit board, eliminating the need for separate screws and fastening elements. The integration reduces the total number of components while maintaining reliable fixation.
Solution Approach 2:
The locking component serves multiple functions: it acts as both a fastening element to secure the circuit board to the chassis and a locking element to prevent accidental disconnection. The operating portion integrated into the locking body allows for easy engagement and disengagement, combining securing and releasing functions in a single component.
2Reliability
If close engagement configuration of BTB connectors is used to enhance server performance, then the computation operation stability is improved, but the plugging or unplugging of connectors becomes difficult
Solution Approach 1:
The locking component incorporates an operating portion that can be easily manipulated to transition between locked and unlocked states. The locking body is designed to engage with the locking hole securely during normal operation, providing stable connection. When the operating portion is actuated, the locking body disengages from the locking hole, allowing the circuit board to be removed. This dynamic design maintains stability during use while enabling easy maintenance.
3Ease of operation
If a locking assembly with sliding locking rod is used, then the ease of assembly and maintenance is improved, but the device complexity increases
Solution Approach 1:
The locking component is segmented into distinct functional portions: the locking body that engages with the locking hole, and the operating portion that facilitates engagement and disengagement. This segmentation allows each portion to be optimized for its specific function while working together as an integrated unit, improving ease of operation without excessive complexity.

AI summary
An electronic device includes a chassis, a first circuit board, and a second circuit board. The chassis includes a bottom plate. The first circuit board includes a first connector. The second circuit board includes a board body, a second connector, and a locking assembly. The board body is configured to be slid on the bottom plate. The locking assembly includes an operating portion and a locking rod. The operating portion is connected to the board body. The locking rod is configured to be slid between a locked position and a released position along the operating portion. A locking end of the locking rod is toward to the board body. When the second connector and the first connector are connected to each other, and the locking rod is at the locked position, the locking end of the locking rod is in a locating hole of the bottom plate.
