Insulating Bus Bar Bracket With Elastic Fixing for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating brackets in motor vehicle cell modules allow bus bars to move due to manufacturing errors, leading to scratching and instability during vibration, which affects reliability and durability.
Innovation Solution
An insulating bracket design with mounting holes and elastic members that secure bus bars by abutting against opposite sides, allowing for adjustable fit and preventing movement, using securing members and elastic contacts to stabilize the bus bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mounting space of the insulating bracket has margin to accommodate manufacturing errors, then the adaptability is improved, but the bus bar has movement space which leads to scratching and reduced reliability
Solution Approach 1:
The patent introduces elastic members (springs) that change their physical state from rigid to flexible, allowing the mounting structure to adapt to manufacturing variations while maintaining firm contact with the bus bar. The elastic member compresses within a predetermined range to accommodate dimensional deviations without creating movement space that causes scratching.
Solution Approach 2:
The patent transforms the static rigid mounting structure into a dynamic system where the elastic member can deform and recover. This dynamic characteristic allows the structure to absorb manufacturing errors through elastic deformation while maintaining stable contact with the bus bar, preventing relative movement that would cause scratching.
2Ease of manufacture
If the mounting space has margin for manufacturing error, then the ease of manufacture is improved, but the stability during vibration is reduced causing bus bar surface damage
Solution Approach 1:
The patent incorporates elastic members that act as cushioning elements before vibration or movement occurs. These elastic members are pre-installed in the mounting structure to absorb and dampen vibrations, preventing direct contact and potential scratching between the insulating bracket and bus bar during operational vibrations.
3Reliability
If the bus bar is securely fixed to prevent movement, then the reliability is improved, but the adaptability to manufacturing errors is reduced
Solution Approach 1:
The patent uses elastic members that can change their compression state to accommodate manufacturing variations. When the bus bar is installed with dimensional deviations, the elastic member compresses within its elastic limit to maintain firm contact, ensuring reliable fixation without requiring precise manufacturing tolerances.

AI summary
Provided are an insulating bracket and a cell module. The insulating bracket includes a main body, a securing member, and an elastic member. The main body is formed with at least one mounting hole extending through the main body in a first direction and configured for a bus bar to be mounted on. The securing member and the elastic member are disposed on the hole wall of each mounting hole at intervals. The securing member is configured to abut against a first side surface of the bus bar. The elastic member is configured to abut against a second side surface of the bus bar. The elastic member always has a tendency to urge the bus bar to move toward and press against the securing member.
