Circular Connector Shell Locking for Vibration-Stable Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Relative displacement between the inner and outer shells of a male plug mechanism in circular connectors leads to difficult alignment and detachment in vibration environments, causing interrupted power, signal, and data transmission.
Innovation Solution
A male plug mechanism with a clamping member and spring leaves to limit the outer shell's deviation, combined with positioning bulges and clamping parts in both mechanisms for stable connection, and a quick lock assembly for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional male plug mechanism without a clamping member is used, then the structure is simple, but relative displacement occurs between the inner shell and outer shell, causing alignment difficulty and detachment in vibration environments
Solution Approach 1:
The male plug mechanism is divided into functional segments: the clamping member as an independent limiting component, the inner shell containing terminal assembly, and the outer shell providing protection. This segmentation allows each part to perform its specific function while maintaining overall simplicity
Solution Approach 2:
The clamping member is pre-installed between the inner and outer shells to establish the limiting relationship before assembly is complete. This preliminary positioning prevents relative displacement from occurring in the first place, rather than attempting to correct it afterward
2Manufacturing precision
If no clamping member is used to limit the outer shell, then the manufacturing process is simple, but alignment between male plug and female socket becomes difficult
Solution Approach 1:
The clamping member automatically performs the alignment function through its geometric constraint between the inner and outer shells. When the shells are assembled, the clamping member self-adjusts to the correct position, eliminating the need for complex external alignment tools or procedures
3Reliability
If the male plug mechanism lacks a clamping structure, then the device is simple, but it detaches easily in vibration environments causing transmission interruption
Solution Approach 1:
The clamping member applies a preliminary constraining force in the opposite direction of potential vibration-induced displacement. By pre-establishing this counteracting force, the connection is protected against detachment before vibration occurs
Solution Approach 2:
The connector employs a circular cylindrical structure with the clamping member positioned to provide radial constraint. This curved geometry distributes vibrational forces evenly around the connection, preventing localized stress concentration that would lead to detachment

Function Achieved in This Case
Ensures stable connection and prevents detachment in vibration environments, maintaining consistent power, signal, and data transmission quality.
Implementation Method 1
spring leaves are arranged circumferentially on one side of the clamping member close to the outer shell, and the spring leaves are butted with an inner wall of the outer shell

AI summary
The present invention discloses a male plug mechanism, a female socket mechanism and a circular connector using same. In the present invention, the male plug shell assembly is arranged to protect the male plug terminal assembly and prevent damage to the male plug terminal assembly, and the outer shell is connected with an outer side of the inner shell through the clamping member to prevent circumferential deviation of the outer shell relative to the inner shell, so that the male plug mechanism is easy to align with the female socket mechanism during use, and the outer shell will not be moved axially in vibration and other environments, having a good stability of connection with the inner shell and the female socket mechanism.
