Detachable Charging End Assembly Signal Terminal Guide Leg
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging base terminals are not easily replaceable, making them unsuitable for applications subject to high wear due to frequent use with charging guns, leading to wear issues affecting electrical contact.
Innovation Solution
A detachable charging end assembly for a charging base, comprising a charging end housing with signal terminals and power terminals, where each terminal is divided into two parts for easy replacement, allowing the charging end assembly to be connected and disconnected from a connecting end assembly, facilitating the replacement of worn terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If terminals are made fixed and integrated into the charging base, then structural stability is improved, but replaceability deteriorates
Solution Approach 1:
The terminal is divided into two separate parts: a first terminal portion fixed in the charging base and a second terminal portion attached to the charging gun. This segmentation allows the first portion to remain stable and fixed while enabling the second portion to be easily attached and detached, thereby maintaining both structural stability and replaceability.
2Ease of repair
If terminals are made detachable for easy replacement, then ease of repair is improved, but connection reliability deteriorates
Solution Approach 1:
The terminal components are pre-designed with complementary connection structures (contact portions and corresponding receptacles) that ensure proper alignment and secure connection before use. This preliminary design of the connection interface guarantees reliable electrical contact while maintaining ease of replacement.
3Ease of manufacture
If the charging base is made as a single integrated unit, then manufacturing simplicity is improved, but maintenance complexity deteriorates
Solution Approach 1:
The charging base is designed with a modular terminal structure where the first terminal portion is separately manufacturable and then fixed into the base. This segmentation simplifies manufacturing by allowing specialized production of terminal components while reducing maintenance complexity, as only the terminal portion needs to be accessed or replaced rather than the entire charging base.

AI summary
A charging assembly for a charging base comprises a charging end assembly detachably connectable to a connecting end assembly to form the charging base. The charging end assembly includes a charging end housing defining a plurality of first openings, and a plurality of signal terminals received in a corresponding one of the plurality of first openings. Each signal terminal includes a main body and a guide leg extending from an end thereof. Each guide leg contracting radially inward relative to an outer wall of the main body and adapted to bias a spring sheet of a lead frame and guide the outer wall of the main body to be inserted into contact with the spring sheet.
