Bulkhead Connector Self-Locking Thread for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulkhead connectors face issues with loosening in vibrating environments and difficulty in adapting to different plate thicknesses, particularly in threaded and fixed ring buckle connections.
Innovation Solution
A self-locking structure for bulkhead connectors featuring a connector housing with an outer thread and a nut member with an inner thread, incorporating an elastic locker that engages with a groove for secure fitting, allowing adaptation to varying plate thicknesses while preventing loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded connection is used for fixation, then it can be adapted to cylinder body plates with different thicknesses and is simple to operate, but it is easy to loosen in a vibration environment for a long time
Solution Approach 1:
The fixation system is segmented into multiple independent locking elements (elastic locking elements with corresponding grooves) distributed around the threaded connection, allowing each element to independently prevent loosening while the threaded connection maintains adaptability to different plate thicknesses
Solution Approach 2:
The elastic locking elements automatically engage with the grooves during the tightening process and self-lock without requiring additional operations or components, providing anti-loosening functionality that activates itself in response to vibration or loosening forces
2Reliability
If a fixed ring buckle connection is used, then it can maintain good fixation effect in a vibration environment for a long time, but it can only be adapted to cylinder body plates with a specific thickness and is difficult to disassemble
Solution Approach 1:
The nut member is designed to perform multiple functions: it provides the threaded connection for adaptability to different plate thicknesses, incorporates elastic locking elements for vibration resistance, and maintains ease of disassembly through the removable nut structure, combining features of both previous connection methods
3Reliability
If a fixed ring buckle connection is used, then it can maintain good fixation effect in a vibration environment for a long time, but it is difficult to disassemble
Solution Approach 1:
The locking mechanism transitions from a static fixed ring buckle structure to a dynamic elastic locking system where the elastic locking elements can be easily engaged during assembly and disengaged during disassembly, providing both vibration resistance and operational ease
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 self-locking structure provides secure fixation and sealing in vibrating environments and accommodates different plate thicknesses, with easy unlocking and disassembly.
Implementation Method 1
an elastic locking element arranged on the nut member. Upon a thread fit between the inner thread of the nut member and the outer thread of the connector housing, at least a portion of the elastic locking element engages with the groove to form a self-locking of the thread fit

AI summary
A bulkhead connector comprises a connector housing, a nut member and a self-locking structure. The nut member is removably fitted to the connector housing to secure the bulkhead connector to a target plate body. An outer surface of the connector housing is formed with an outer thread, and an inner surface of the nut member is formed with an inner thread. The self-locking structure includes a groove formed in the outer surface of the connector housing, and an elastic locking element arranged on the nut member. Upon a thread fit between the inner thread of the nut member and the outer thread of the connector housing, at least a portion of the elastic locking element engages with the groove to form a self-locking of the thread fit.
