Coaxial Cable Connector Spring Mechanism for Partial Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coaxial cable connector structures are labor-intensive to fasten due to a small outer contact area of the annular nut, making it difficult to rotate manually, and are inconvenient for use in narrow spaces where the connection base is often located.
Innovation Solution
A coaxial cable connector structure with a spring disposed on the bottom of the annular nut that contacts the connection base to establish an electrical connection with the inner tube when the connection base is not completely screwed in, allowing for easier signal transmission and vibration suppression, and incorporating an O-ring for sealing to prevent water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the annular nut is used for fastening the coaxial cable connector, then the connector can be secured to the connection base, but the small outer contact area makes it difficult to rotate manually and requires repeated rotations
Solution Approach 1:
A spring mechanism is introduced as an intermediary between the connection base and the annular nut. The spring makes contact with the inner tube when the connector is loosened or not completely screwed onto the connection base, providing electrical connectivity without requiring complete fastening. This mediator allows the system to achieve functional electrical connection with reduced mechanical engagement, saving time and effort.
2Reliability
If the connection base is disposed on the back side of equipment, then the connector can be fastened securely, but users must move equipment to access it in narrow spaces
Solution Approach 1:
The spring mechanism enables partial threading action to achieve functional electrical connection. The spring contacts the inner tube when the connector is loosened or not completely screwed onto the connection base, allowing the system to achieve sufficient electrical connectivity with partial engagement. This partial action approach maintains connection reliability while improving accessibility in narrow spaces.
3Reliability
If the spring is disposed inside the annular nut, then electrical connection is maintained when not fully fastened, but the spring occupies space within the nut structure
Solution Approach 1:
The spring is nested inside the annular nut structure, with the spring disposed within the internal cavity of the nut. The spring's outer diameter is designed to be smaller than or equal to the inner diameter of the annular nut, allowing it to fit within the existing nut geometry. This nesting approach maintains electrical connection continuity while minimizing additional structural complexity.

Implementation Method 1
a spring is disposed on the bottom of the annular nut for the end surface of the connection base towards the annular nut to contact the spring and electrically connect the inner tube
Implementation Method 2
provides vibration suppression, and incorporating an O-ring for sealing to prevent water ingress

AI summary
A coaxial cable connector structure including a sleeve and an annular nut on the front end of the sleeve is disclosed, wherein an inner tube is disposed inside the sleeve for connecting the coaxial cable, and a spring is disposed on the bottom of the annular nut for the end surface of the connection base towards the annular nut to contact the spring and electrically connect the inner tube when the connection base is screwed into the annular nut, so that the coaxial cable connector structure can transmit signals when it is not completely screwed onto the connection base, and provide the effect of vibration suppression from the compressed spring having its two ends abutted against the bottom of the annular nut and the end surface of the connection base by the elastic restoring force when the connection base is completely screwed onto the connection base.
