Grounding Connector C-Shaped Spring Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial cable connectors often fail to achieve secure grounding, leading to interruptions in signal transmission due to incomplete contact between the nut and the inner sleeve.
Innovation Solution
A grounding electrical connector design featuring a C-shaped contact spring that is movably arranged around the inner sleeve, ensuring the nut remains in contact with the inner sleeve for secure grounding, even if not fully locked with the threaded interface connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nut is not fully locked with the threaded interface connector, then the device complexity is reduced and ease of operation is improved, but the grounding contact reliability deteriorates leading to signal transmission interruption
Solution Approach 1:
The C-shaped contact spring acts as an intermediary component between the nut and the inner sleeve. It provides continuous grounding contact through its elastic deformation, mediating the connection even when the nut is not fully locked, thus maintaining reliability while allowing ease of operation
Solution Approach 2:
The contact spring is designed to be movable and elastic rather than rigid. It can dynamically adjust its position and deformation state to maintain continuous contact between the nut and inner sleeve, ensuring reliable grounding contact while accommodating variations in locking state
2Reliability
If a rigid grounding structure is used to ensure reliable grounding contact, then the grounding contact reliability is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The contact spring serves as a simple intermediary element that provides reliable grounding contact without requiring complex mechanisms. Its C-shaped design with elastic properties achieves the grounding function through straightforward structural means
Solution Approach 2:
The contact spring utilizes changes in its physical state (elastic deformation) to maintain contact. By allowing the spring to deform within its elastic limit, the structure maintains reliable grounding contact through parameter changes rather than complex mechanical arrangements

Function Achieved in This Case
This design ensures reliable signal transmission and electrical performance by maintaining effective grounding contact between the nut and inner sleeve, preventing signal interruptions.
Implementation Method 1
a C-shaped contact spring back and forth movably arranged around the tapered section of the inner sleeve in contact with the nut. The C-shaped contact spring is back and forth movable to keep the nut in contact with the inner sleeve

AI summary
A grounding electrical connector includes: an inner sleeve and an outer sleeve coaxially positioned around the inner sleeve, the inner sleeve serving to receive the central conductor and the insulator of the cable, the outer sleeve serving to receive the external conductor and the skin of the cable, the inner sleeve having an outer flange, an interface section, a tapered section positioned between the outer flange and the interface section, and a rear end extension section; a nut having an inner flange positioned around the tapered section of the inner sleeve; and a C-shaped contact spring back and forth movably arranged around the tapered section of the inner sleeve in contact with the nut. The C-shaped contact spring is back and forth movable to keep the nut in contact with the inner sleeve so as to achieve good grounding effect.
