Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors face issues with reduced bonding stress due to ineffective elasticity and material fatigue, leading to detachment and safety concerns, especially when connecting multiple devices, and are inconvenient for assembly and maintenance.
Innovation Solution
A cable connector with a switchover structure featuring a plug holder with a screw harness portion and a switching unit, including a knob and switching ring, which allows for rotational switching to securely connect with different socket types, ensuring tight locking, easy assembly, and convenient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If springs are used as switching and caulking structures in conventional connectors, then the connector can achieve initial bonding stress and connection firmness, but after long term use the elasticity and displacement of springs deteriorate resulting in reduced bonding stress and loss of switching and caulking functions
Solution Approach 1:
The patent removes the spring component from the connector design. The switching and caulking functions previously performed by springs are replaced by a pure mechanical structure consisting of a plug holder, socket holder, and engagement nail, eliminating the material fatigue and elasticity loss issues inherent in spring-based designs.
Solution Approach 2:
The connector is divided into distinct functional components: a plug holder containing pin terminals, a socket holder containing socket terminals, and an engagement nail for mechanical coupling. This segmentation allows each component to perform its specific function without relying on the degradation-prone spring mechanism.
2Adaptability or versatility
If conventional socket connectors are designed with fixed specifications for locking, then each plug can only fit with a single kind of socket, but this results in material fatigue and structure wear from long term use causing the tight fitting function to deteriorate
Solution Approach 1:
The connector design incorporates a rotatable plug holder that can switch between different connection modes. This dynamic element allows the same plug to adapt to different socket types (with or without caulking portions) without requiring multiple specialized connectors, while the mechanical engagement nail maintains reliable tight fitting through rotational locking rather than repeated insertion/removal of spring-loaded components.
3Ease of operation
If springs are located in the inner chamber of the plug for switching and caulking functions, then the connector can achieve connection, but assembly and mounting, retreat and maintenance become inconvenient
Solution Approach 1:
By removing the spring from the inner chamber, the patent dramatically simplifies the internal structure. The plug holder becomes a straightforward mechanical component without hidden elastic elements, making assembly straightforward and maintenance accessible. The engagement nail provides the necessary mechanical coupling without requiring complex spring mechanisms inside the plug body.

AI summary
The invention is a cable connector with a switchover structure, comprising a plug connector having a plug rubber core, a housing, a pin terminal, a protruding rib and a wire; a plug holder harnessed on an outer edge of the plug rubber core movably; and a switching unit combined with the plug holder movably, furthermore, the said switching unit mentioned above is harnessed on the outer edge of the plug rubber core and is positioned between the housing and the plug holder. Therefore, by rotational switching of the switching unit may be utilized for the plug holder to be joined to different kinds of socket connectors, such that the effects and advantages of tight locking, detachment prevention, easy of assembly, easy of retreating, convenient replacement and maintenance, ease of operation and applicability to at least two different kinds of socket connectors are achieved as the cable connector and a socket connector are butted together.
