Sliding Locking Structure for Server Expansion Card Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Locking components in electronic devices, such as servers, often have complex and inconvenient locking structures that are costly to implement and operate.
Innovation Solution
A locking structure comprising first and second connectors, locking members, a sliding member, and a holding member, which uses protrusions and fastening grooves to securely fix expansion cards and housing components, allowing for easy locking and unlocking through a sliding mechanism with resilient members and latching slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking structure is used to secure expansion cards in server cabinets, then the locking function is achieved, but the structure becomes complicated and operation becomes inconvenient
Solution Approach 1:
The locking structure is divided into independent functional modules: locking members with fastening grooves, a sliding member for actuation, resilient members for force application, and latching slots for position fixation. Each module performs a specific function, allowing the overall system to achieve reliable locking while maintaining structural simplicity through functional decomposition.
2Reliability
If a traditional locking structure is used to secure expansion cards in server cabinets, then the locking function is achieved, but operation becomes inconvenient and cost increases
Solution Approach 1:
The locking mechanism transitions from static to dynamic operation through the sliding member that moves along the sliding direction. The resilient members dynamically apply locking force as the sliding member moves, and the latching slots provide dynamic position fixation. This dynamic design allows convenient single-handed operation while maintaining secure locking function.
3Ease of operation
If a simple locking mechanism is used, then operation is convenient and cost is reduced, but the locking function may be insufficient
Solution Approach 1:
Multiple locking functions are merged into a single integrated structure. The locking members with fastening grooves, sliding member, resilient members, and latching slots work together as one unified mechanism. This merging achieves reliable locking function through coordinated action of all components while maintaining simplicity and ease of operation as a single integrated unit.

AI summary
Locking structure includes a first connector, a second connector, a locking member, a sliding member, and a holding member. The first connector includes a first cavity and a first protrusion in the first cavity. The second connector includes a second cavity and a second protrusion in the second cavity. The locking member is slidably received in the second cavity and extends into the first cavity. A peripheral wall of the locking member defines a fastening groove. The sliding member extends into the second cavity and abuts the locking member to drive the locking member to move toward the first protrusion and the second protrusion so that two opposite side walls of the fastening groove press against opposite sides of the first protrusion and the second protrusion. The sliding member defines a latching slot. The holding member includes a latching member for latching in or disengaging from the latching slot.
