F-Type Connector Locking Mechanism for Secure Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional F-type connectors often experience signal loss or degradation due to loose connections and risk of damage from over-tightening, as users may apply insufficient or excessive torque, and are prone to loosening from vibration and thermal cycling.
Innovation Solution
A connector with a locking mechanism that compresses a male connector over a female connector, using a collet with optional threading and a latch system to securely engage and prevent unwanted loosening, thereby maintaining electrical performance without requiring excessive torque.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a person uses a wrench to tighten the F-connector fastener, then sufficient torque (10-25 in-lbs) can be applied to secure the connection, but the wrench is bulky and inconvenient and there is a risk of over-tightening and damaging the attachment structure
Solution Approach 1:
The connector incorporates a self-tightening mechanism with a collet that automatically engages and secures the attachment structure when the connector is assembled. The collet's spring-loaded design allows it to self-adjust and apply appropriate clamping force without requiring external tools or manual torque application, thereby eliminating the need for wrenches while ensuring reliable connection security.
Solution Approach 2:
The patent replaces the traditional mechanical threaded fastening system (which requires wrenches for torque application) with a collet-based clamping mechanism. This new mechanism uses spring force and friction engagement instead of threaded mechanical advantage, substituting the complex torque-controlled mechanical system with a simpler spring-loaded clamping system that is both tool-free and damage-free.
2Ease of operation
If a person tightens the F-connector fastener by hand, then the operation is simple and convenient, but only 4-5 in-lbs of torque can be applied which is insufficient to properly secure the connection
Solution Approach 1:
The connector incorporates a self-tightening mechanism with a collet that automatically engages and secures the attachment structure when the connector is assembled. The collet's spring-loaded design allows it to self-adjust and apply appropriate clamping force without requiring external tools or manual torque application, thereby eliminating the need for wrenches while ensuring reliable connection security.
Solution Approach 2:
The collet is designed as a dynamic, spring-loaded component that can automatically adjust its clamping force based on the engagement conditions. Unlike a static threaded fastener that requires precise torque control, the spring mechanism dynamically adapts to ensure sufficient connection security while remaining easy to operate.
3Reliability
If a threaded connection is used between male and female connectors, then the connection can be secured with adequate torque, but vibration and thermal cycling can cause the connection to loosen and separate
Solution Approach 1:
The patent replaces the traditional mechanical threaded fastening system (which requires torque application and is susceptible to loosening) with a collet-based clamping mechanism. This new mechanism uses spring force and friction engagement instead of threaded mechanical advantage, substituting the complex torque-controlled mechanical system with a simpler spring-loaded clamping system that is both tool-free and damage-free.
Solution Approach 2:
The collet is designed as a dynamic, spring-loaded component that can automatically adjust its clamping force based on the engagement conditions. Unlike a static threaded fastener that requires precise torque control, the spring mechanism dynamically adapts to ensure sufficient connection security while remaining easy to operate.
4Reliability
If excessive torque is applied to tighten the F-connector fastener, then the connection can be securely secured, but the attachment structure may be damaged
Solution Approach 1:
The connector incorporates a self-tightening mechanism with a collet that automatically engages and secures the attachment structure when the connector is assembled. The collet's spring-loaded design allows it to self-adjust and apply appropriate clamping force without requiring external tools or manual torque application, thereby eliminating the need for wrenches while ensuring reliable connection security.
Solution Approach 2:
The patent changes the fundamental parameter of force application from high-magnitude torque (which risks damage) to moderate spring force (which is safe and sufficient). The spring-loaded collet operates within elastic deformation limits, applying continuous gentle pressure that secures the connection without risking damage to the attachment structure.
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 locking mechanism effectively reduces signal loss, prevents damage from over-tightening, and maintains a secure connection under various environmental conditions, such as vibration and thermal cycling.
Implementation Method 1
A connector with a locking mechanism that compresses a male connector inwardly over a female connector, and thereby locks the male and female connectors together
Implementation Method 2
In order to maintain a tight electrical connection, and to achieve the intended electrical performance, manufacturers and industry standards often require an F-type connector to be tightened to an attachment structure

AI summary
Connectors with locking mechanisms and associated systems and methods are disclosed herein. A connector in accordance with an embodiment of the present technology, for example, can include a connector body having an inner surface defining a first bore and a collet movably received in the first bore. The collet can have an inner surface defining a second bore that is configured to receive a mating second connector. The connector can further include a locking mechanism that is operably coupled to the connector body and has an open position and a closed position. The collet is configured to operably engage the second connector when the locking mechanism is in the closed position and release the second connector when the locking mechanism in the open position.
