Solution Overview
Problem
Current grounding connectors require special tools for installation and are costly due to their complex design with multiple metal components, which increases production costs and material usage.
Innovation Solution
A direct burial metal ground lug made of phosphor bronze with a simplified design featuring two portions with through and threaded holes, connected by a joint portion and secured with threaded screws, allowing for easy installation without special tools and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional grounding connectors with multiple metal components are used, then structural integrity is maintained, but manufacturing cost and material usage increase
Solution Approach 1:
The patent combines multiple separate metal components (connector body, grounding elements, fastening mechanisms) into a single integrated ground lug structure. This merging reduces the total quantity of metal materials required while maintaining the structural integrity and electrical conductivity needed for grounding applications.
Solution Approach 2:
The ground lug is designed as a multi-functional component that simultaneously provides mechanical connection, electrical conductivity, and grounding functionality. This universal design eliminates the need for separate specialized components, reducing overall material usage and manufacturing complexity.
2Reliability
If traditional grounding connectors with complex designs are used, then durability is ensured, but installation complexity increases
Solution Approach 1:
The ground lug incorporates pre-configured segmented elements (threaded holes, attachment points, grounding terminals) that are integrated into a single piece. This segmentation allows for simplified installation where components can be directly assembled without complex alignment procedures, while the integrated design ensures durability through reduced connection points.
3Manufacturing precision
If traditional grounding connectors requiring special tools are used, then precise installation is achieved, but ease of operation decreases
Solution Approach 1:
The ground lug is designed with self-aligning features and standard threaded holes that allow installers to use common tools rather than specialized equipment. The integrated design with pre-positioned attachment points enables precise installation through simple fastening operations, eliminating the need for complex tooling while maintaining installation accuracy.

AI summary
The invention relates to a direct burial ground lug. The lug is preferably constructed of a phosphor bronze material. The block may have two through holes to install two conductors, rods, cables, and the like. Stainless steel threaded screws are used to hold the rod and ground conductor in a stable condition. The threaded screws insert into threaded holes positioned perpendicular to the through holes. The direct burial ground lug allows the ground rod and ground conductor to be connected for a continuous grounding system.
