Power Distribution Box Bracket for Impact-Absorbing Connector Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power distribution box assemblies are prone to deformation upon impact, which can damage the electronic components housed within.
Innovation Solution
A power distribution box assembly featuring a lower cover with a support wall and a bracket that includes a weakening portion and a support arm, allowing the bracket to deform inwardly upon impact, thereby protecting the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wall of the lower cover is used to attach the connector directly, then the structure is simple, but the electronic components are vulnerable to impact damage
Solution Approach 1:
A bracket is introduced as an intermediary component between the lower cover and the connector. The bracket includes an attachment portion that connects to the lower cover and a support portion that supports the connector, thereby protecting electronic components from impact damage while maintaining structural simplicity
Solution Approach 2:
The bracket is divided into distinct functional portions: an attachment portion for connecting to the lower cover and a support portion for supporting the connector. This segmentation allows each portion to be optimized for its specific function while working together as a unified protective structure
2Strength
If a rigid bracket is used to support the connector, then the connector is securely held, but the bracket cannot absorb impact forces
Solution Approach 1:
The bracket includes a weakening portion that changes the structural parameters of the bracket, creating a designated deformation zone. This allows the bracket to maintain strength for supporting the connector while enabling controlled deformation to absorb impact forces during collisions
Solution Approach 2:
The weakening portion is pre-designed in the bracket to create a controlled deformation zone that will absorb impact energy before it reaches the electronic components. This beforehand cushioning mechanism ensures that impact forces are mitigated while the bracket still provides secure support for the connector during normal operation

AI summary
A power distribution box assembly for supporting a wire harness assembly having a connector includes a lower cover, a bracket and a clip. The lower cover includes a mounting portion having a first hole. The bracket is attached to the mounting portion and includes a second hole, a portion of the bracket is spaced apart from an outer surface of the lower cover. The clip engages the second hole of the bracket so as to attach to the connector to the bracket. The power distribution box assembly is configured to distribute power to the vehicle and provide a structure for mounting a component and mitigating the damage to the electric components housed therein due to an impact.
