Bayonet Circular Connector Locking With Audible Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bayonet-type locking and unlocking systems for circular connectors face challenges such as displacement under vibrations, lack of perceptible locking indication, and movement during locking or traction, especially in harsh environments and applications with short contact strokes.
Innovation Solution
A bayonet-type locking and unlocking system with an audible indicator, featuring a socket, plug body, external ring, locking ring, and locking piece, utilizing an intermediate washer and return spring to ensure secure locking without connector displacement, and an unblocking ramp for easy unlocking via simple rotation, with audible feedback confirming complete locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet-type locking system is used to prevent connector displacement under vibrations, then connection reliability is improved, but the system requires an operating set and elastic system that complicates the device structure
Solution Approach 1:
The patent extracts the elastic system from the traditional bayonet locking mechanism. The locking system uses a rigid locking ramp with a hollow machining that imprisons the lug, eliminating the need for elastic components while maintaining vibration resistance and connection reliability.
Solution Approach 2:
The locking ramp is divided into distinct functional zones: an approach ramp for initial engagement, a locking ramp with hollow machining for secure locking, and an unblocking ramp for release. This segmentation allows each zone to perform its specific function without requiring complex elastic mechanisms.
2Reliability
If a traditional bayonet locking system is used, then connectors can be locked together, but recoil occurs during lug passage through the locking ramp hollow or displacement occurs under cabling traction
Solution Approach 1:
The locking ramp is segmented into three distinct parts: an approach ramp with gradual slope for smooth initial engagement, a locking ramp with hollow machining for secure imprisonment of the lug, and an unblocking ramp for controlled release. This segmentation eliminates recoil by providing a gradual engagement path and dedicated zones for each phase of the locking operation.
Solution Approach 2:
The approach ramp performs preliminary action by gradually guiding the lug into the locking position before it engages the hollow machining. This preliminary engagement prevents sudden impacts and recoil during the locking process.
3Reliability
If strong locking torque is required for secure locking, then connection reliability is improved, but the locking indication becomes imperceptible to the operator
Solution Approach 1:
The patent uses visual indication through color changes or visual features on the connector housing. The housing includes visual indicators that change appearance or position when the locking ramp engages the hollow machining, providing clear feedback to the operator that secure locking has been achieved, even when high torque is applied.
4Adaptability or versatility
If connectors are designed for dark or difficult-to-access environments, then adaptability is improved, but visual confirmation of complete locking becomes inconvenient
Solution Approach 1:
The connector housing includes visual indicators that provide clear feedback without requiring the operator to view the complete locking mechanism. These indicators may change color, position, or appearance to signal that secure locking has been achieved, making operation feasible in dark or difficult-to-access environments.
Solution Approach 2:
The system incorporates feedback mechanisms through visual indicators on the housing that immediately inform the operator of the locking state. This feedback allows operators to confirm secure connection without needing to visually inspect the internal locking components, enabling reliable operation in environments with limited visibility.
