Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power connector assemblies face challenges in ensuring a firm and stable connection between male and female connectors, as well as reliable wire coupling, especially under vibrations, which can lead to temporary or permanent disconnection.
Innovation Solution
A securely latched power connector assembly design featuring a male and female connector with conductive terminals and insulating casings, where the conductive terminals have inclined portions and pins to securely retain the wire cores and facilitate electrical connection through coupling structures, preventing misalignment and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connector assemblies are used, then the structure is simple, but the connection stability under vibration is poor and disconnection risk increases
Solution Approach 1:
The connector is divided into multiple functional components: a first coupling structure for initial connection, a second coupling structure for reinforcement, and a latch mechanism for final securing. This segmentation allows each component to perform a specific function, collectively achieving high connection stability without excessive overall complexity.
Solution Approach 2:
The connector employs preliminary actions through its multi-stage coupling mechanism. The first coupling structure establishes initial contact, the second coupling structure reinforces the connection, and the latch mechanism pre-positions itself to engage and secure the connection before vibration occurs, preventing disconnection proactively.
2Reliability
If simple connector design is used, then manufacturing is easy, but wire retention under vibration is insufficient
Solution Approach 1:
The connector features nested coupling structures where the second coupling structure is positioned within or around the first coupling structure, and the latch mechanism nests within the housing. This nesting arrangement provides multiple retention stages without significantly increasing manufacturing complexity, as components can be molded or formed in integrated assemblies.
3Strength
If multi-structure coupling is implemented, then connection firmness improves, but device complexity increases
Solution Approach 1:
The patent merges multiple coupling functions into an integrated connector assembly. The first and second coupling structures, along with the latch mechanism, are combined into a single connector unit that engages with a corresponding receptacle. This merging provides strong, multi-stage connection firmness while avoiding the complexity of separate discrete components.

AI summary
A securely latched power connector assembly includes a male connector and a female connector connected with a first leading wire and a second leading wire, respectively. A first conductive terminal of the male connector has a first buckle portion for retaining a core of the first leading wire. A second conductive terminal of the female connector has a second buckle portion for retaining a core of the second leading wire. When the connectors are combined, a hollow plug of the male connector is inserted into a hollow socket of the female connector, and the first coupling structures of the male connector and the second coupling structures of the female connector are firmly coupled, while the second pin of the second conductive terminal being inserted into the hollow plug to contact with the first pin of the first conductive terminal, thereby achieving electrical connection.
