Busbar Assembly Lead-Out Structure for Reliable Tab Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing busbar assemblies, the tabs of electrodes often fail to fully contact the conductive members, resulting in poor welding effects and unreliable electrical connections.
Innovation Solution
A busbar assembly design featuring a tab lead-out slit with lead-out walls, where at least one lead-out wall is formed on the conductive member, ensuring full contact between the tab and the conductive member, enhancing the reliability of the electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tabs are inserted into the busbar bracket for connection, then the electrical connection between tabs and conductive members is established, but the tabs often fail to fully contact the conductive members resulting in poor welding effect and unreliable electrical connection
Solution Approach 1:
The lead-out walls are pre-formed on the conductive members before tab insertion, creating a predetermined contact structure that guides the tab into proper alignment and ensures complete contact surface engagement during the welding process
Solution Approach 2:
The lead-out walls act as an intermediary structure between the tab and the conductive member, providing a transition zone that ensures proper contact alignment and enhances the reliability of the electrical connection through improved contact geometry

AI summary
The disclosure provides a busbar assembly and a cell module. The busbar assembly includes a busbar bracket, a conductive member, and a tab lead-out slit. The busbar bracket has a first side and a second side facing away from each other. The conductive member is arranged on the busbar bracket. The tab lead-out slit extends from the first side to the second side and passes through the busbar bracket. The tab lead-out slit has two opposite lead-out walls, and at least one of the lead-out walls is formed on the conductive member. In the disclosure, since at least one lead-out wall of the tab lead-out slit is formed on the conductive member, when the tab is inserted into the corresponding lead-out slit, the tab easily contacts the lead-out wall, so that the tab fully contacts the conductive member, and the reliability of the connection between the two is improved.
