Central Latching Mechanism for Compact Card Edge Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card edge connectors occupy valuable space on motherboards due to the design of their latching mechanisms, which can increase the size and cost of electronic systems.
Innovation Solution
A latching system where a projection/protrusion of a latching member enters an opening on the card with contact pads, allowing the latching member to be mounted centrally within the connector slot, reducing the space required for latching components and integrating the latching mechanism into areas not conventionally used for electrical components, with a pivotally mounted latching member that secures the card by pivoting into a locked position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional latching mechanisms are used in card edge connectors, then the card can be securely retained in the connector slot, but the connector occupies valuable space on the motherboard due to the design of the latching mechanisms
Solution Approach 1:
The patent combines the latching function with the alignment rib structure. The alignment rib serves dual purposes: guiding the card into proper alignment and providing the latching mechanism through protrusions that engage with openings in the card. This integration eliminates the need for separate latching components, reducing the overall space occupied by the connector on the motherboard while maintaining secure card retention
Solution Approach 2:
The alignment rib is designed to perform multiple functions simultaneously: it provides mechanical alignment for the card, serves as a guide during insertion, and acts as the latching mechanism through its protrusions that engage with card openings. This multi-functionality reduces the number of separate components needed, thereby reducing the space required for the connector assembly
2Adaptability or versatility
If separate latching components are used, then the latching mechanism can be designed independently, but this increases the device complexity and manufacturing cost
Solution Approach 1:
The latching function is merged into the alignment rib structure itself. The protrusions on the alignment rib serve as latching elements that engage with openings in the card, eliminating the need for separate latching components. This integration simplifies the overall device structure while maintaining the necessary latching functionality
Solution Approach 2:
The alignment rib is designed to perform multiple functions: mechanical alignment, insertion guidance, and latching. By making the alignment rib multi-functional, the patent reduces the total number of components needed in the connector assembly, thereby reducing device complexity and manufacturing cost

AI summary
A card edge connector with latching that enables a compact connector. The connector includes a latch, centrally located along the connector. The latch may be aligned with an alignment rib of the connector housing, reducing the space required for the latch. In some embodiments, portions of the latch may be bifurcated so that the latch may straddle the rib. In this way, space for a latch in a circuit assembly using the connector may be less than in conventional connector with latches on each end.
