Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for electric vehicle battery boxes are unstable, prone to disconnection, and difficult to install, failing to meet requirements for high voltage, high current, water resistance, and safety due to their design and material limitations.
Innovation Solution
A connector system featuring a rotating clamping structure with positioning pins and stoppers that allows the male and female connectors to be locked and separated securely at any position, combined with waterproof structures for stability and reliability, using thermoplastic engineering plastics to reduce weight and prevent electric leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing connectors use metal alloy housing, then strength and durability are improved, but weight increases and installation becomes difficult
Solution Approach 1:
The patent employs composite material construction by combining metal alloy components (for strength-critical elements like positioning pins and stoppers) with non-metallic housing materials. This allows the connector to achieve both high strength and reduced weight, resolving the contradiction between durability and weight.
2Manufacturing precision
If existing connectors require position adjustment before fixation, then connection precision is improved, but installation complexity increases
Solution Approach 1:
The connector incorporates pre-designed positioning structures (positioning slots and positioning pins) that automatically guide and align the male and female connectors during insertion. This preliminary positioning action eliminates the need for manual adjustment, achieving both high connection precision and easy installation.
Solution Approach 2:
The self-locking mechanism automatically engages the positioning pins with positioning slots and secures the connection without requiring external adjustment tools or manual intervention. The connector performs its own positioning and fixation functions, simplifying the installation process while maintaining precision.
3Device complexity
If existing connectors lack locking mechanism, then device complexity is reduced, but connection stability deteriorates
Solution Approach 1:
The connector employs a dynamic self-locking mechanism where the stoppers rotate or move automatically upon insertion to engage with corresponding features on the mating connector. This dynamic action provides reliable locking without requiring complex external locking devices, achieving both simplicity and stability.
4Reliability
If connector separation is difficult, then connection stability is improved, but operation ease deteriorates
Solution Approach 1:
The self-locking mechanism is designed to be reversible through a simple dynamic action. By applying a specific rotational or linear force to the stoppers, the connector can be easily unlocked and separated. This dynamic design maintains strong locked connection during normal use while enabling easy separation when needed.

AI summary
A connector includes a male connector, a female connector and a rotating clamping structure. The male connector includes a first housing with multiple channels, the female connector includes a second housing with at least one positioning slot. The rotating clamping structure includes a third housing, multiple first positioning pins, multiple stoppers and multiple second positioning pins. The rotating clamping structure can realize the locking or separation of the male connector and the female connector.
