Connector Alignment Pin With Slot For ZIF Misalignment Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with zero insertion force (ZIF) and low insertion force (LIF) mechanisms do not prevent the cover from being moved to the closed position before the electrical component is properly aligned, leading to potential misalignment and damage during engagement, and require overcoming significant resistance for proper connection.
Innovation Solution
Incorporating alignment pins with slots that receive an edge portion of the electrical component, ensuring proper alignment and preventing engagement until the component is fully positioned, thereby reducing the risk of damage and simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cover is used in ZIF/LIF connectors to facilitate easier connection, then insertion force is reduced, but the cover can be moved to closed position before proper alignment, causing misalignment and potential damage
Solution Approach 1:
The alignment pin performs preliminary alignment action before the cover can be closed. The pin protrudes from the connector body and must be received within an alignment opening on the component assembly before the electrical contacts can engage, ensuring proper alignment is established prior to the potential harmful engagement state
Solution Approach 2:
The alignment pin acts as an intermediary element between the connector body and the component assembly. It mediates the alignment process by providing a physical reference that must be properly positioned before the electrical contacts engage, preventing direct engagement before alignment is complete
2Productivity
If the cover is moved to closed position before proper alignment, then engagement is attempted, but the electrical contacts become damaged due to misalignment
Solution Approach 1:
The alignment pin provides preliminary anti-action by preventing the cover from being closed before proper alignment is achieved. The pin physically blocks the closing motion unless the component assembly is properly aligned, counteracting the potential harmful engagement that would occur without the pin
3Reliability
If alignment pins with slots are added to ensure proper alignment, then damage is prevented, but the number of components in the connector assembly increases
Solution Approach 1:
The alignment pin merges multiple functions into a single component: it provides alignment reference, physical blocking of premature closure, and mechanical guidance for proper engagement. This consolidation reduces the need for separate alignment mechanisms, brackets, or positioning features that would otherwise be required

AI summary
An electrical connector for connection to an electrical component assembly along a connection axis is provided. The electrical connector includes a body holding a first array of electrical contacts. The first array of electrical contacts are configured to electrically connect to a second array of electrical contacts of the electrical component assembly. An alignment pin extends outwardly from the body. The alignment pin is configured to be received within an alignment opening of the electrical component assembly for aligning the electrical component assembly with the body. The alignment pin includes at least one slot configured to receive an edge portion of the electrical component assembly that at least partially defines the alignment opening thereof.
