Pick Up Cap Attachment to Stiffener for Connector Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies with pick up caps risk incorrect operation and contact damage during CPU insertion due to the pick up cap being attached to the metal clip, leading to potential misalignment and improper attachment.
Innovation Solution
The pick up cap is attached to a stiffener that covers the metal clip, requiring it to be removed before CPU insertion to prevent such issues, ensuring accurate alignment and secure attachment without damaging contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pick up cap is attached to the metal clip, then the pick up cap can be easily manipulated by vacuum suction device, but it may be forgotten to be removed before CPU insertion causing wrong operation
Solution Approach 1:
The pick up cap is segmented from the metal clip attachment system. Instead of being directly attached to the clip, the cap is attached to the stiffener, creating a separate attachment system that can be independently removed without affecting the clip or CPU insertion process.
Solution Approach 2:
The stiffener serves as an intermediary component between the pick up cap and the connector assembly. The cap attaches to the stiffener rather than directly to the clip, allowing the cap to be removed before CPU insertion while maintaining its manipulative function during assembly.
2Object-affected harmful factors
If the pick up cap covers the metal clip, then the clip is protected, but it may interfere with CPU alignment and insertion
Solution Approach 1:
The coverage function is segmented from the clip itself. The stiffener provides the structural framework that supports the pick up cap, allowing the cap to cover and protect the clip area without the clip being directly involved in the coverage mechanism, thus avoiding interference with CPU alignment.
Solution Approach 2:
The pick up cap is removed as a preliminary action before CPU insertion. By attaching the cap to the stiffener rather than the clip, the system ensures the cap must be removed first, preventing any potential interference with CPU alignment and insertion while maintaining protection during assembly.
3Reliability
If the pick up cap is attached to the stiffener, then it must be removed before CPU insertion preventing wrong operation, but it adds an additional attachment point
Solution Approach 1:
The stiffener serves multiple functions: it provides structural support to the connector housing, serves as an attachment point for the pick up cap, and maintains the overall integrity of the connector assembly. This multi-functionality avoids adding extra components while ensuring the cap must be removed before CPU insertion.
4Manufacturing precision
If the pick up cap attaches to the stiffener instead of the clip, then CPU insertion is not interfered with, but the cap may not be as securely positioned
Solution Approach 1:
The attachment system is segmented to attach the cap to the stiffener rather than the clip. The stiffener provides a stable, rigid structure with sufficient surface area and structural integrity to securely position the pick up cap while maintaining proper spacing from the CPU insertion path.

Function Achieved in This Case
This design prevents incorrect operations and contact damage by ensuring the pick up cap is securely detached before CPU insertion, facilitating precise alignment and attachment, thus enhancing the reliability of the electrical connector assembly.
Implementation Method 1
The pick up cap provides a smooth flat portion facilitating to be sucked by a vacuum suction device, thereby manipulating the electrical connector assembly on a desire location of a substrate circuit such as a printed circuit board (PCB).

AI summary
An electrical connector assembly includes an electrical connector and a pick up cap. The connector includes an insulative housing, a plurality of contacts received in the housing, a stiffener being able to support and secure the housing, and a metal clip. The housing defines a conduction region for supporting a central processing unit (CPU). The clip is disposed on the housing to press the CPU upon the contacts. The pick up cap provides a smooth flat portion facilitating to be sucked by a vacuum suction device, thereby manipulating the electrical connector assembly on a desire location of a substrate circuit such as a printed circuit board (PCB). The pick up cap attaches to the stiffener, and the pick up cap covers at least a portion of the clip. Thus, user must take away the pick up cap before mounted the CPU to the connector.
