Retractable Plug Pin Assembly for Protected Power Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power devices have conductive pins that are exposed and prone to rust, deformation, or cracking, leading to reduced electrical connection quality and service life.
Innovation Solution
A power device design featuring a retractable conductive pin, where the pin is stored in a pathway within the body and extends only when the plug is assembled, reducing exposure and enhancing protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive pins are exposed outside the body, then electrical connection is achieved, but the conductive pins are prone to rust, deformation, or cracking
Solution Approach 1:
The conductive pin is nested within a pathway in the body, with only the necessary portion exposed for electrical connection. This nesting structure protects the majority of the conductive pin from environmental factors while maintaining electrical functionality.
Solution Approach 2:
The conductive pin is designed to be movable between an extended position (for electrical connection) and a retracted position (for protection). This dynamic design allows the pin to transition between exposed and protected states, reducing susceptibility to rust, deformation, and cracking.
2Object-affected harmful factors
If conductive pins are retractable, then protection from rust and deformation is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional components: the body with pathway, the movable conductive pin, and the plug. This segmentation allows the retractable mechanism to be implemented in a localized area without complicating the entire device structure.
Solution Approach 2:
The conductive pin automatically extends and retracts based on the presence or absence of the plug, without requiring additional control mechanisms. The plug itself serves as the actuating element, simplifying the overall device complexity while achieving the protective function.

AI summary
A power device is provided. The power device includes a body and a plug rotatably assembled on the body. The body includes a lower housing and a connection element in the lower housing. The connection element includes a pathway and a conductive pin at least partially disposed in the pathway. The plug includes an upper housing and an upper pin rotatably and pivotally connected to the upper housing. The upper pin is used to electrically connect to an external power supply. The plug rotates relative to the body to move the conductive pin along the pathway from a storage position to an extending position to electrically connect to the upper pin.
