Surge Protector Anti-Off Structure for Stable Pluggable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surge protectors with pluggable mechanisms suffer from unstable assembly due to low deformation resistance, leading to easy separation of components once the clamping fails.
Innovation Solution
A surge protector with an anti-off structure featuring a sliding limit device and fixing limit device, including hole covers, elastic components, and limit protruding blocks, which ensure a stable and reliable clamping mechanism by preventing the pluggable module from being detached from the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the deformation resistance of the housing is made small to facilitate insertion and removal, then the ease of operation is improved, but the stability of the assembly deteriorates
Solution Approach 1:
The anti-off structure segments the clamping function into two independent parts: the original clamping mechanism for insertion/removal and the new anti-off structure for stability. The anti-off structure includes a hole cover with a positioning rib that engages with a limiting protrusion, creating a separate stabilization system that does not interfere with the clamping mechanism's deformation-based operation.
Solution Approach 2:
The anti-off structure is preliminarily configured to engage automatically when the pluggable module is inserted. The hole cover is pre-positioned with the positioning rib that will engage with the limiting protrusion on the pluggable module, providing stability before any potential clamping failure occurs.
2Ease of manufacture
If the clamping resistance is reduced for easy assembly, then the ease of manufacture is improved, but the reliability of the connection deteriorates
Solution Approach 1:
The anti-off structure acts as an intermediary mechanism between the clamping system and the pluggable module. It provides an additional layer of connection reliability through the positioning rib and limiting protrusion engagement, independent of the clamping resistance level. This intermediary structure ensures that even if clamping fails, the connection remains reliable.
3Ease of operation
If the housing deformation resistance is made small to facilitate pluggable module removal, then the ease of operation is improved, but the strength of the connection deteriorates
Solution Approach 1:
The connection strength is segmented into two functional components: the clamping mechanism providing initial connection strength through deformation, and the anti-off structure providing secondary strength through mechanical engagement. The positioning rib engaging with the limiting protrusion creates a distinct load-bearing path that does not depend on housing deformation resistance.
Solution Approach 2:
The anti-off structure provides beforehand cushioning against connection failure. The positioning rib and limiting protrusion are pre-configured to engage and provide backup support, cushioning the system against the weakness of low deformation resistance housing by preventing complete separation even if clamping fails.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-off structure provides a stable and reliable connection, preventing the pluggable module from being pulled out unless the anti-off state is unbuckled, ensuring a secure assembly and easy removal when needed.
Implementation Method 1
Both ends of the elastic component abut the hole cover and the top of the external terminal connection part, respectively, such that the elastic component has an acting force to constantly drive the hole cover to slide horizontally toward the pluggable module installation slot
Implementation Method 2
When the pluggable module is inserted, the hole cover is slid to form a clamping between the first positioning rib of the hole cover and the protrusion to prevent the hole cover from returning
Implementation Method 3
a part of the hole cover protrudes into the pluggable module installation slot and is clamped with the fixing limit device of the pluggable module to limit the pluggable module from being detached from the base

AI summary
A surge protector with an anti-off structure includes a pluggable module and a base. The base includes external terminal connection parts on both sides. The top of the external terminal connection part of the base is provided with a sliding limit device. Both sides of the pluggable module are provided with limit protruding blocks. The sliding limit device includes a hole cover, and the hole cover is slidably connected to the top of the external terminal connection part. When the pluggable module is completely inserted, a part of the hole cover protrudes into the pluggable module installation slot and is clamped with a fixing limit device of the pluggable module to limit the pluggable module from being detached from the base. When the pluggable module is removed, the hole cover is moved toward both sides, such that the hole cover is separated from the fixing limit device.
