Power Feed Connector Terminal Integration for Actuator Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power feed connectors for motors in actuators require a large number of components and complex fitting processes, leading to increased costs and reduced work efficiency due to the need for separate fitting of motor and capacitor terminals.
Innovation Solution
A power feed connector design that integrates motor current application terminals with extension portions and capacitor contact portions, allowing for simplified fitting and reduced component count, where the capacitor is sandwiched between the capacitor contact portions, and auxiliary contact portions are used to maintain the capacitor's position, all formed using the same device and process to standardize machined parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capacitor contact portions are fitted separately to the housing, then reliable electrical connection to capacitor is achieved, but the number of components increases and fitting work becomes complicated
Solution Approach 1:
The capacitor contact portions are integrated into the motor current application terminals, forming a single unified component. This merging eliminates the need for separate fitting operations while maintaining reliable electrical connection to the capacitor, directly resolving the contradiction between connection reliability and component complexity
2Reliability
If capacitor contact portions are fitted separately to the housing, then reliable electrical connection to capacitor is achieved, but fitting work becomes complicated and time-consuming
Solution Approach 1:
By integrating capacitor contact portions into the motor current application terminals, the fitting process is simplified from multiple separate operations to a single unified fitting action, significantly improving productivity while maintaining connection reliability
3Adaptability or versatility
If multiple separate components are used for motor terminals and capacitor contacts, then functional requirements are met, but manufacturing cost increases
Solution Approach 1:
The integration of capacitor contact portions into motor current application terminals reduces the total component count, simplifying manufacturing processes and lowering costs while maintaining all necessary functional adaptabilities through the unified design
4Ease of operation
If capacitor contact portions protrude from extension portions, then capacitor positioning is simplified, but the structure becomes more complex
Solution Approach 1:
The terminal is divided into functional segments (extension portion and capacitor contact portion), where the protruding contact portion naturally guides and positions the capacitor during assembly, achieving ease of operation while the integrated design prevents excessive complexity

AI summary
The number of components can be reduced and the fittability can be improved so that reduction in the cost can be realized. A power feed connector for feeding power to a motor provided in an actuator includes: two motor current application terminals for applying a current to the motor; two capacitor contact portions; a capacitor for applying a current to the capacitor contact portions respectively; and a housing to which the two motor current application terminals, the two capacitor contact portions, and the capacitor are fitted, wherein each of the motor current application terminals includes an extension portion and a connection portion for applying a current to the motor, and wherein each of the capacitor contact portions protrudes from the extension portion.
