Flat Surge Protector Layout for Ultra-Thin Tripping Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surge protectors are too large to meet the requirements of compact, ultra-thin products, as they typically have a single-pole width of 18 mm and a corresponding low-temperature soldering spot tripping mechanism width of about 15 mm.
Innovation Solution
The surge protector design incorporates a flat-shaped surge protection component with a fuse component arranged on one side, utilizing a tripping assembly that includes a separation component with an elastic component to reduce the width of the tripping assembly, allowing for a compact ultra-thin design with a single-pole width of about 9 mm or 12 mm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional surge protector design is used, then the protection function is reliable, but the width is too large (18 mm) to meet compact product requirements
Solution Approach 1:
The patent repositions the tripping assembly from a horizontal arrangement to a vertical arrangement along the height direction. The fuse component is entirely located at one side of the surge protection component in the height direction, changing the spatial dimension of component layout. This dimensional change reduces the width from 18 mm to 9-12 mm while maintaining all protection functions through the vertical stacking of components.
2Length of moving object
If the tripping assembly width is reduced, then the overall surge protector width decreases, but the solder connection reliability may be compromised
Solution Approach 1:
The fuse component is divided into multiple segments: a first segment connected to the line pin, a second segment connected to the surge protection component via solder, and an intermediate segment connecting these two segments. This segmentation allows the solder connection to be positioned optimally within the compact structure, maintaining connection reliability while enabling reduced overall width. The intermediate segment provides mechanical and electrical continuity between the distributed connection points.

Function Achieved in This Case
This design effectively reduces the width of the surge protector to meet the demands of ultra-thin products while maintaining the necessary protection functions, facilitating the formation of compact surge protection apparatuses.
Implementation Method 1
a separation component coupled between the fuse component and the surge protection component via an elastic component, and adapted to be moved to a tripping position under an action of an elastic force of the elastic component when the solder is melted
Implementation Method 2
the solder is adapted to be melted in a case where a tripping condition is satisfied
