Capacitor Holding Carrier With Insulating Bearing Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for holding electrical capacitor assemblies with potential housings are costly due to the need for insulating materials and complex attachment processes, which complicates the efficient storage and connection of multiple assemblies.
Innovation Solution
A carrier system with through-openings and bearing rings that allow capacitor assemblies to be securely held without direct contact, using either insulating or conductive materials, and a clamping mechanism to create a reliable holding connection, enabling easy assembly and preventing mechanical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating plates are used to hold capacitor assemblies with potential housings, then electrical isolation is achieved, but production cost and assembly complexity increase
Solution Approach 1:
The patent extracts the insulating function from the structural holding function by introducing a separate bearing ring made of insulating material. The bearing ring is placed between the capacitor assembly housing and the carrier, so that the carrier itself does not need to be insulating. This separation allows the carrier to be made from simple, inexpensive material while maintaining electrical isolation through the bearing ring alone.
Solution Approach 2:
The bearing ring acts as an intermediary element between the capacitor assembly and the carrier. It provides both mechanical support (holding the assembly in place) and electrical isolation (preventing contact between the potential housing and the carrier). This intermediary component resolves the contradiction by enabling simple carrier construction while ensuring reliable electrical isolation.
2Reliability
If insulating plates are used to attach capacitor assemblies, then electrical isolation is ensured, but production cost increases
Solution Approach 1:
The insulating function is extracted from the carrier and concentrated in the bearing ring. This allows the majority of the structure (the carrier) to be made from inexpensive, simple material, while only the small bearing ring needs to be made from insulating material. This significantly reduces the overall production cost compared to making the entire carrier from insulating material.
Solution Approach 2:
Instead of making the entire carrier from expensive insulating material, the patent applies insulating material locally only where it is needed - in the bearing ring that contacts the capacitor assembly housing. This localized application of insulating material maintains electrical isolation while minimizing production costs.
3Device complexity
If direct mechanical contact is made between carrier and capacitor housing, then simple structure is achieved, but electrical isolation is compromised
Solution Approach 1:
The bearing ring serves as an intermediary element that maintains electrical isolation while preserving structural simplicity. It is a simple ring-shaped component that fits between the capacitor housing and carrier, providing both mechanical support and electrical insulation without complicating the overall structure.
Solution Approach 2:
The holding function is segmented into two separate functions: mechanical support (provided by the carrier and clamping mechanism) and electrical isolation (provided by the bearing ring). This segmentation allows each component to be optimized for its specific function while keeping the overall structure simple.
4Reliability
If complex attachment processes are used, then secure holding is achieved, but assembly time and cost increase
Solution Approach 1:
The bearing ring is designed to be self-positioning and self-retaining. It features an interference fit with the capacitor housing that automatically centers and secures the ring during assembly, eliminating the need for complex alignment procedures or additional fastening operations. The clamping mechanism simply needs to apply radial force, and the bearing ring automatically performs the holding function.

AI summary
The invention relates to an arrangement for holding a plurality of electric capacitor assemblies (3), particularly assemblies having live housings. The arrangement comprises a carrier (31) having a through-passage (4) for introducing one of the assemblies (3) and further comprises at least one bearing ring (45) for supporting an assembly (3). The bearing ring (45) is adjusted to the dimensions of the through-passage (4) and the assembly (3) such that the assembly (3), when extending through the through-passage (4), is in contact with the inner edge of the through-passage (4) via the bearing ring (45), but not in direct contact to the inner edge of the through-passage (4).
