Integrated Partition Post for PCB Grounding and Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing printed circuit boards in electronic devices require separate components for positioning and grounding, leading to complex assembly procedures and increased costs due to the use of electric conductive elastic sheets, which are not efficient in reducing electromagnetic interference.
Innovation Solution
A partition post with an electric conductive spring integrated into its columnar body, featuring connection rings, through slots, and an arrow-shaped elastic buckle claw, allows for stable positioning and grounding of printed circuit boards by transmitting static electricity and noise signals to a metal housing, thereby simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components (engagement post and electric conductive elastic sheet) are used for positioning and grounding, then positioning and grounding functions are provided, but assembly procedure becomes complicated and cost increases
Solution Approach 1:
The patent combines the engagement post and electric conductive elastic sheet into a single integrated partition post. The partition post includes a columnar body with an elastic buckle claw for positioning and an electric conductive spring for grounding, both integrated into one component. This merging eliminates the need for separate components and simplifies the assembly procedure while maintaining both positioning and grounding functions.
Solution Approach 2:
The partition post is designed to perform multiple functions simultaneously: it provides positioning through the elastic buckle claw, grounding through the electric conductive spring, and structural support through the columnar body. This multi-functionality reduces the total number of components needed and simplifies the overall assembly process.
2Object-affected harmful factors
If electric conductive elastic sheet is used for grounding, then electromagnetic interference is reduced, but assembly complexity and cost increase
Solution Approach 1:
The electric conductive spring is integrated into the partition post structure, eliminating the need for a separate electric conductive elastic sheet. This integration reduces the total component count and simplifies manufacturing while maintaining the grounding effect that reduces electromagnetic interference.
Solution Approach 2:
The patent uses a spring structure that can be manufactured more economically than traditional elastic sheets. The spring design allows for simpler manufacturing processes and potentially lower material costs while achieving the same grounding function.
3Stability of the object's composition
If multiple separate components are used for positioning and grounding, then positioning stability is achieved, but assembly time increases
Solution Approach 1:
The partition post integrates the positioning function (elastic buckle claw) and grounding function (electric conductive spring) into a single component. This allows both functions to be installed simultaneously in one assembly operation, reducing assembly time while maintaining positioning stability through the buckle connection effect.

AI summary
The present invention relates to a partition post used on a printed circuit board, which comprises an insulation post member and an electric conductive spring. The top and the bottom of the insulation post member are respectively and protrudingly installed with an upper and a lower connection rings, and the bottom surface of the lower connection ring is longitudinally extended with an arrow-shaped elastic buckle claw; the electric conductive spring is sleeved on the insulation post member, the top and the bottom thereof are respectively installed with an upper and a lower guide parts composed of plural spiral rings and at the locations corresponding to the upper and the lower connection rings; so static electricity and/or noise signal generated by each electric component on the printed circuit board can be transmitted through the electric conductive spring to the electric conductive member and thereby providing a grounding effect.
