CPU Connector Pick-Up Cap for Dual Half-Housing PCB Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for CPUs require a pair of half housings and additional clips for assembly on a PCB, which is inefficient and costly due to the need for multiple components.
Innovation Solution
A single pick-up cap with claws and positioning blocks is used to securely grasp and mount a pair of half housings, allowing simultaneous assembly and soldering to the PCB, eliminating the need for additional clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pair of pick-up caps and additional clips are used to mount the pair of half housings on the PCB, then the half housings can be securely mounted, but the assembly process becomes complex and costly due to multiple components
Solution Approach 1:
The patent combines the pick-up cap and additional clips into a single integrated pick-up cap structure. The new design incorporates clip-like securing features directly on the pick-up cap, eliminating the need for separate additional clips while maintaining the secure mounting function.
Solution Approach 2:
The pick-up cap is designed to perform multiple functions: it grasps the half housings during assembly, provides positioning alignment, and secures the half housings to the PCB simultaneously. This multi-functional design replaces what previously required multiple separate components.
2Reliability
If a pair of pick-up caps and additional clips are used for assembly, then the half housings can be securely held, but the assembly process becomes time-consuming and less efficient
Solution Approach 1:
By merging the grasping and securing functions into a single pick-up cap, the assembly process is streamlined. The operator can simultaneously grasp both half housings and secure them to the PCB in one operation, eliminating the need for separate steps with multiple components.
Solution Approach 2:
The pick-up cap is pre-designed with integrated securing features that enable both grasping and mounting to be accomplished in a single preliminary action, rather than requiring sequential operations with multiple components.
3Reliability
If additional clips are used to secure the pick-up caps to the half housings, then the connection is secure, but the component cost increases
Solution Approach 1:
The patent merges the additional clips into the pick-up cap structure itself, creating an integrated component. This eliminates the need for separate additional clips while maintaining the secure connection function, thereby reducing component quantity and cost.

AI summary
An electrical connector is essentially composed of a pair of half housings opposite to each other in a longitudinal direction to commonly form a receiving cavity for receiving a CPU. Each half housing is equipped with a plurality of contacts with corresponding contacting sections upwardly extending into the receiving cavity for mating with the CPU. A single pick-up cap includes a plate with a plurality of claws adapted to be engaged within locking recesses in exterior sides of the half housings, a plurality of positioning blocks adapted to extend into the receiving cavity so as to cooperate with the claws to sandwich the periphery wall of the housing therebetween in the longitudinal direction for securing the half housings to the pick-up cap. Therefore, both the pair of half housings may be grasped by the single pick-up cap for mounting and soldering to PCB at the same time.
