Cable Connector Coupling Structure with Quick-Release Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors face challenges in achieving secure fastening while allowing for quick detachment, especially under external forces or vibrations, as existing methods either ensure security at the cost of quick release or vice versa.
Innovation Solution
A coupling structure for cable connectors featuring a first connection head with an external threaded portion and a second connection head with insertion holes, a fastening sleeve, positioning ring, and a quick-release fastening ring that securely fastens through rotational engagement and rapidly detaches by reversing the rotation or horizontal movement, utilizing internal and external threaded elements and resilient elements for secure and efficient connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If insertion connection method is used, then quick detachment is enabled, but secure connection under external pulling force or vibrations cannot be ensured
Solution Approach 1:
The patent combines two connection methods into a single coupling structure: the first connection head and second connection head are inserted into each other (insertion connection) while simultaneously being secured by threaded fastening elements that engage with threaded portions (threaded fastening). This merging allows the connector to achieve both quick detachment capability and secure connection under external forces.
Solution Approach 2:
The coupling structure transitions from a static connection state to a dynamic one: the fastening elements can be rotated to engage or disengage from the threaded portions, allowing the connector to switch between a locked secure state and an unlocked detachable state. This dynamic mechanism enables both secure fastening and quick release operations.
2Reliability
If rotational coupling method or threaded fastening method is used, then reliable connection is ensured, but quick detachment cannot be allowed
Solution Approach 1:
The coupling structure is segmented into distinct functional components: the insertion connection provides the basic coupling framework, while multiple distributed fastening elements provide secure fastening. This segmentation allows the secure fastening function to be independently controlled through rotation of the fastening elements, enabling reliable connection during operation while permitting quick detachment when needed by simply rotating the fastening elements to disengage.
3Reliability
If multiple fastening elements are distributed around the coupling structure, then secure fastening is improved, but device complexity increases
Solution Approach 1:
The fastening elements serve multiple functions simultaneously: they provide secure fastening through threaded engagement, distribute mechanical loads around the coupling structure, and can be collectively controlled through a single rotational operation for both locking and unlocking. This multi-functionality reduces the need for separate mechanisms, thereby limiting the increase in device complexity despite the distribution of multiple fastening elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable fastening effect while enabling rapid detachment, ensuring secure power delivery and signal transmission by allowing for secure engagement and quick release through rotational or horizontal movement of the quick-release fastening ring.
Implementation Method 1
a resilient element received in the accommodating space. The quick-release fastening ring is movable toward a second rod with respect to the fastening sleeve. When the quick-release fastening ring is moved toward the flange to compress the resilient element, each pressing portion of the quick-release fastening ring is rapidly separated from the protruding portion of each fastening element
Implementation Method 2
an internal threaded portion of each fastening element is engaged with the external threaded portion of the first joint part

AI summary
A coupling structure of a cable connector includes a first connection head (1) and a second connection head (2). The first connection head (1) includes a first joint part (11), multiple insertion terminals (12), and an external threaded portion (13) disposed on the first joint part (11). The second connection head (2) includes a second joint part (21), multiple insertion holes (22), a fastening sleeve (23), a socket (24) formed between the fastening sleeve (23) and the second joint part (21), a positioning ring (25) receiving the fastening sleeve (23), a plurality of fastening elements (26) arranged between the positioning ring (25) and the fastening sleeve (23), and a quick-release fastening ring (27). The quick-release fastening ring (27) rotatably presses on the fastening elements (26). An internal threaded portion (261) of each fastening element (26) is engaged with the external threaded portion (13). Therefore, the first connection head (1) and the second connection head (2) can be securely fastened to each other and can be quickly detached from each other.
