Sliding Electrical Connector for Drawer Power Supply Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrical equipment with a drawer that is designed to be slid out for service or testing, existing solutions fail to maintain a stable power supply to the circuit board within the drawer due to the need for extended power wires that can accommodate the drawer's movement.
Innovation Solution
An electrical connector system comprising a support bracket and connection terminals that maintain sliding electrical contact with a bus bar mounted on the cabinet's inner sidewall, ensuring continuous power supply to the circuit board as the drawer is drawn out, utilizing a sliding channel design and elastic contact portions to maintain contact during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power wires are extended to accommodate drawer movement, then the drawer can be drawn out for service and testing, but the power supply stability deteriorates and power delivery becomes interrupted
Solution Approach 1:
The patent applies the dynamics principle by transforming the static power connection into a dynamic sliding contact system. The connection terminal with sliding contact portion moves together with the drawer, maintaining continuous sliding electrical contact with the bus bar during drawer movement. This dynamic adaptation allows the power supply to remain stable while accommodating the full range of drawer motion, resolving the contradiction between drawer accessibility and power supply stability.
2Ease of operation
If power wires are extended to accommodate drawer movement, then the drawer can be drawn out for service and testing, but the power delivery becomes interrupted
Solution Approach 1:
The dynamic sliding contact mechanism ensures continuous power delivery throughout the drawer's movement range. The connection terminal maintains electrical contact with the bus bar via sliding contact, eliminating interruptions in power supply that would otherwise occur during drawer extension and retraction, thus maintaining full productivity during service and testing operations.
Solution Approach 2:
The patent implements continuity of useful action by ensuring uninterrupted electrical contact between the connection terminal and bus bar throughout the entire drawer movement cycle. The sliding contact design maintains constant electrical connection, allowing power delivery to continue without interruption during drawer extension, service operations, and retraction, thereby sustaining continuous productive operation.
