Power Converter Connector Layout for Compact Installation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power conversion devices require large installation spaces due to connectors protruding horizontally, necessitating significant space for installation.
Innovation Solution
The power conversion device is designed with connectors that protrude from the outer wall surface of a surrounding wall portion in an inclined direction relative to the partition wall, reducing the horizontal protrusion and allowing for a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors are arranged horizontally on the side surface of the case, then external connectors can be easily connected, but the installation space becomes large
Solution Approach 1:
The patent changes the arrangement dimension of connectors from horizontal (side surface) to vertical (front surface), allowing connectors to be mounted in the vertical direction rather than protruding horizontally. This dimensional change enables compact installation while maintaining connection functionality.
2Ease of manufacture
If connectors protrude horizontally from the case, then cable connection is simplified, but the device requires larger installation space
Solution Approach 1:
The connector mounting orientation is changed from horizontal protrusion to vertical mounting on the front surface. Cables can still be easily mounted in the vertical direction, which simplifies connection while reducing the horizontal footprint and overall installation space requirement.
3Reliability
If connectors are arranged on the side surface, then connection functionality is achieved, but additional shielding is required increasing weight and cost
Solution Approach 1:
The patent extracts the connectors from the side surface arrangement and relocates them to the front surface. This repositioning eliminates the need for additional shielding that would be required for side-mounted connectors, thereby reducing weight and cost while maintaining full connection functionality.

AI summary
A power conversion device includes: a first connector held by a support plate; a second connector held by the support plate to be adjacent to the first connector; and a bus bar connecting the first connector and the second connector to at least a capacitor unit and a DC/DC converter unit, in which the support plate includes a surrounding wall portion surrounding a partition wall portion from a side thereof, and the first connector and the second connector are provided to protrude from an outer wall surface of the surrounding wall portion and are formed such that cables are mountable thereon in a direction inclined relative to a wall surface of the partition wall portion.
