Burn-in Socket Protecting Device with Spring Arm Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burn-in sockets face instability issues due to the protecting device easily moving downward from the base during assembly, which can damage electrical contacts and affect the socket's reliability.
Innovation Solution
A burn-in socket design featuring a protecting device with spring arms and stoppers that move from a first position spaced apart from the base to a second position close to the base, utilizing first and second stoppers to engage with projections on the base, ensuring stable movement and protection of contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the protecting device is positioned at the first position spaced apart from the base, then the contacts are protected from damage, but the socket becomes unstable during assembly
Solution Approach 1:
The protecting device is designed to be movable between two positions: a first position spaced apart from the base for protecting contacts during transportation, and a second position close to the base for providing stability during assembly. The device includes spring arms with stoppers that can engage with corresponding projections on the base to secure the protecting device at either position, allowing it to dynamically adapt to different operational requirements.
2Ease of operation
If the protecting device moves easily from the first position to the second position, then the assembly process is simplified, but the contacts become vulnerable to damage
Solution Approach 1:
Spring arms with stoppers act as intermediary elements between the protecting device and the base. These spring arms can engage with corresponding projections on the base to secure the protecting device at the first position during transportation, preventing accidental movement that could damage contacts. During assembly, the spring arms allow controlled movement to the second position while maintaining stability once positioned.

Function Achieved in This Case
The design enhances the stability and protection of electrical contacts during assembly and use, preventing damage and ensuring reliable operation by allowing controlled movement of the protecting device between positions.
Implementation Method 1
a pair of spring arms extending upwardly from opposite sides of the bottom plate. Each spring arm has a first stopper for engaging with the first projection at the first position, and a second stopper for engaging with the second projection at the second position
