Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors face issues with looseness over time due to reduced joining stress, leading to ineffective electrical connections and safety hazards, and are not adaptable to multiple socket types, making them inefficient and difficult to maintain.
Innovation Solution
A switch assembly for cable connectors that incorporates a plug holder with a switching unit and an elastic element, allowing for rotational switching and secure locking with different socket types, facilitating easy assembly, maintenance, and detachment prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If inner threads and outer threads are used for switching and caulking structures, then the connector can be applicable to two types of sockets, but the joining stress is reduced after long term use, resulting in failure or displacement and loss of switching and caulking functions
Solution Approach 1:
The patent employs a dynamic switching mechanism where a switching component can rotate between different positions to engage with either inner threads or outer threads. This dynamic adjustment allows the connector to adapt to different socket types while maintaining reliable joining stress through the elastic thrust of coil springs that continuously apply force to keep the switching component engaged with the selected thread type.
Solution Approach 2:
The connector integrates multiple functions into a single device: it can connect to both inner-threaded and outer-threaded sockets by rotating the switching component to different positions. The same engagement nail and coil spring assembly serve both switching and caulking functions, eliminating the need for separate structures for each function and maintaining reliability across both application modes.
2Reliability
If the connector is designed for firm locking, then cable connecting plugs can be locked firmly, but assembly and mounting, retreat and maintenance become inconvenient
Solution Approach 1:
The switching component can be easily rotated between locked and unlocked positions, allowing convenient assembly and disassembly. The elastic coil springs automatically engage the switching component with the selected thread type when rotation is performed, providing firm locking without requiring complex manual operations. The dynamic nature of the switching mechanism enables simple retreat and maintenance operations.
3Reliability
If engagement nail compresses coil spring to snap firmly, then elastic thrust is applied for plug holder and socket holder to snap firmly, but power transmission interrupt occurs easily and safety problem arises when connector joint is loosened
Solution Approach 1:
The coil springs are pre-compressed to store elastic energy before engagement, creating a cushioning effect that ensures firm snapping when the connector joints engage. This beforehand cushioning maintains consistent joining stress over time, preventing loosening and the resulting power transmission interruptions or safety problems that would occur with rigid, non-compliant connection structures.

AI summary
The present invention is a switch assembly of cable connector, which comprises a plug having a plug rubber core, a housing, a plurality of pin terminals, a protruding rib and a wire; a plug holder harnessed on the outer edge of the plug rubber core movably; a switching unit joining with the plug holder movably, which is harnessed on the outer edge of the plug rubber core movably, and provided between the housing and the plug holder; and an elastic element harnessed on two ends of the plug rubber core and caught at the housing and the switching unit. Thereby, rotational switching is possible by using the switching unit in conjunction with the elastic element, such that the plug holder may be bonded to different types of sockets, in order to achieve the effects of close locking, detachment prevention, easy assembly, ease to retreat, convenient replacement and maintenance, facile to operate and applicability to at least two different kinds of sockets as the cable connector and a socket are bonded.
