Electric Compressor Terminal Assembly with Integrated Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric compressors experience unstable electrical connections between the driver and controller, leading to operational abnormalities and increased assembly complexity due to the number of parts required for terminal fixation.
Innovation Solution
A terminal assembly with a housing divided into multiple spaces, featuring magnet wire-connected terminal parts and a cover part that constrains movement, reducing the number of parts and stabilizing electrical connections through welding and a single-body design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple parts are used to fix terminals, then terminal fixation is achieved, but number of assembling processes increases and productivity decreases
Solution Approach 1:
The cover part integrates multiple fixation functions into a single component that simultaneously secures multiple terminal parts within the housing. This eliminates the need for separate fixing operations for each terminal, reducing the number of assembling processes and improving productivity.
Solution Approach 2:
The cover part serves multiple functions: it covers the terminal housing, fixes the terminal parts in position, and provides structural support. This multi-functionality reduces the total number of parts needed and simplifies the assembly process, directly improving productivity.
2Ease of operation
If terminal parts are not constrained, then assembly is simple, but terminal movement occurs and connection stability deteriorates
Solution Approach 1:
The terminal parts are pre-positioned within the terminal housing before the cover part is installed. The housing structure with its partition walls preliminarily constrains the terminal parts, and the subsequent cover part installation finalizes the fixation without requiring complex adjustment or repositioning operations.

AI summary
A terminal assembly for an electrical compressor may include: a terminal housing having an internal space divided into a plurality of spaces, and fixed to a driver; a plurality of terminal parts positioned in the terminal housing, and each having one side connected to a magnet wire and the other side to form a hole into which an electric conduction pin is inserted; and a cover part coupled to the terminal housing, and constraining the movement of the terminal part. The magnet wire may be connected to the terminal part by welding.
