PCB Voltage Protection Cover with Segmented Chamber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voltage protection solutions for transmission controls in the automotive field are expensive and prone to detachment, leading to potential short circuits due to conductive deposits, and are not specifically designed for printed circuit boards, which require a compact and cost-effective solution to prevent short circuits while allowing fluid penetration and drainage.
Innovation Solution
A voltage protection system for printed circuit boards featuring a slotted design with a mount and a voltage protection cover forming a chamber system, where each printed circuit board strip is housed in a chamber, preventing conductive connections and allowing fluid penetration and drainage, with the option of attaching the cover using various methods and materials, including insulating separating strips and wire guides for secure electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fully sealed connection is used to protect the printed circuit board, then protection against conductive particles is improved, but the risk of detachment and fluid penetration increases
Solution Approach 1:
The printed circuit board is divided into multiple strips that are arranged parallel to each other within a common housing. This segmentation allows the board to be protected as a whole while avoiding the need for a fully sealed connection, as fluid can drain through the gaps between strips without causing detachment or short circuits.
2Object-affected harmful factors
If a grouted adhesive connection is used to seal the interface, then protection against particle impact is improved, but the cost increases and detachment risk increases
Solution Approach 1:
The adhesive grouting step is completely removed from the manufacturing process. Instead of using adhesive to seal the interface, the design relies on the mechanical arrangement of printed circuit board strips within the housing, which naturally provides protection without requiring additional sealing materials or complex assembly steps.
3Reliability
If a larger voltage protection cover is used to accommodate pre-safeguarding and final safeguarding, then protection against fluid penetration is improved, but the installation space and cost increase
Solution Approach 1:
The printed circuit board is segmented into multiple strips that can be arranged compactly within a smaller housing. This segmentation allows the same level of protection to be achieved in a more space-efficient manner compared to using a single large board requiring a larger protective cover.
Solution Approach 2:
Instead of protecting a single large printed circuit board in the plane, the invention transitions to a three-dimensional arrangement where multiple strips are stacked or arranged vertically within the housing. This dimensional change allows for more efficient use of space while maintaining protection effectiveness.

AI summary
A voltage protection for printed circuit boards is provided, which is slotted on one end, such that it has printed circuit board strips, a mount, which is configured to at least partially receive the printed circuit board, and a voltage protection cover, which is configured to be connected to the mount and the printed circuit board, such that a chamber system is formed, in which each printed circuit board strip is disposed inside a chamber, which is formed by the connection between the mount and the voltage protection cover.
