Bus Bar Holder Structure for Fixed Mount and Easy Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protector-equipped bus bars require disassembly and reassembly for maintenance, reducing ease of maintenance due to the need to detach and reattach bus bar protectors to the vehicle body.
Innovation Solution
A holder body and vehicle body fixing structure that allows the bus bar to be removed while the holder body remains fixed to the vehicle body, utilizing a holder main body, a sliding cover, and a hinge cover to facilitate easy removal and assembly of the bus bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bus bar protector is fixed to the vehicle body using a claw structure, then the bus bar protector can be securely fixed, but the entire protector-equipped bus bar must be disassembled and reassembled for maintenance, reducing maintenance ease
Solution Approach 1:
The invention divides the protector-equipped bus bar into separate components: the bus bar protector (with claw structure) remains fixed to the vehicle body, while only the bus bar needs to be removed for maintenance. This segmentation allows the protector to stay in place while the bus bar is independently accessible, resolving the contradiction between secure fixing and ease of maintenance.
Solution Approach 2:
The invention extracts the bus bar from the integrated protector-equipped bus bar assembly, allowing it to be independently removed while the protector remains fixed. This extraction enables maintenance workers to access and remove only the bus bar without disassembling the entire protector structure, improving maintenance ease while preserving fixing reliability.
2Reliability
If the bus bar protector covers the entire bus bar for insulation, then insulation performance is improved, but the connection portions cannot be accessed for maintenance without removing the entire protector
Solution Approach 1:
The invention segments the coverage function by allowing the bus bar protector to cover only the insulation-required portions of the bus bar, while leaving connection portions accessible. This selective coverage maintains insulation performance where needed while improving accessibility for maintenance operations.
Solution Approach 2:
The invention designs the protector structure in advance with predetermined openings or accessible regions at connection portions, so that maintenance workers can access connection portions without removing the entire protector. This preliminary design resolves the contradiction by pre-planning maintenance access paths.

AI summary
A holder body is configured to support a bus bar having a straight portion in a strip shape, and to be fixed to a fixing target of a vehicle body, and includes a holder main body in the shape of a gutter capable of accommodating the straight portion, a cover material in a plate shape assembled onto the holder main body to hold the straight portion, and a pressing portion provided on a side away from the straight portion to press and support the cover material, wherein the pressing portion includes a pressing portion main body in a plate shape provided to be able to engage with the holder main body so as to face the cover material, and a contact rib provided to protrude from the pressing portion main body toward the cover material so as to be able to come into contact with the cover material.
