Pluggable Charging Terminal Structure for Low-Cost Socket Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of charging terminals in charging sockets is difficult and costly due to their design, requiring disconnection of the entire socket for repairs, which complicates the process and increases maintenance expenses.
Innovation Solution
A charging terminal design featuring a main body with a first engagement part for pluggable connection to a mating terminal and a second engagement part for external device connection, allowing for easy detachment and replacement of damaged parts, including a flat conductive sheet with anti-skid surfaces and a tubular second engagement part with a sealing member, facilitating simple maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the charging terminal is designed as a pluggable structure with riveted cable, then the charging socket can be reused multiple times, but the entire charging socket needs to be disconnected for repair when the charging terminal is damaged
Solution Approach 1:
The charging terminal is divided into separable components: the main body with engagement parts and the cable assembly. The cable can be detached and replaced independently from the main body, allowing repair of the cable without affecting the main body or the charging socket. This segmentation enables selective replacement of damaged components.
Solution Approach 2:
The cable assembly is extracted as a separate replaceable component from the charging terminal main body. When the cable is damaged, only the cable needs to be removed and replaced, while the main body remains in place and functional. This extraction principle eliminates the need to disconnect the entire charging socket for cable repairs.
2Duration of action of stationary object
If the charging terminal is designed as a pluggable structure with riveted cable, then the charging socket can be reused multiple times, but the maintenance cost is relatively high
Solution Approach 1:
The cable assembly is designed as a lower-cost, easily replaceable component with a shorter service life compared to the main body. When the cable wears out or gets damaged, it can be replaced with a new, inexpensive cable rather than replacing the entire expensive charging terminal or socket assembly. This reduces overall maintenance costs.
Solution Approach 2:
By segmenting the charging terminal into the main body and cable assembly, the system allows replacement of only the inexpensive cable component rather than the entire expensive assembly. This segmentation strategy significantly reduces maintenance costs while preserving the service life of the main body and charging socket.
3Ease of operation
If the first engagement part uses a flat conductive sheet, then the pluggable connection with the first mating terminal is achieved, but the connection requires precise alignment
Solution Approach 1:
The guide structure is designed to preliminarily align the first engagement part with the first mating terminal before the actual electrical contact is made. The guide structure includes alignment features such as guide rails or positioning edges that automatically orient the conductive sheet correctly as it approaches the mating terminal, reducing the precision requirement for manual alignment.
Solution Approach 2:
The guide structure acts as an intermediary mechanism between the first engagement part and the first mating terminal. It provides a path or channel that guides the conductive sheet into the correct position, mediating the alignment process and ensuring precise connection without requiring high precision in the final positioning action.
