Connector Socket Axial Spring Mounting for Vibration Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector sockets for outdoor applications, such as agricultural machines, face issues with secure sealing against dirt and moisture due to vibration and movement, leading to potential damage and failure of sealing systems, and they are not suitable for large cable cross-sections due to space constraints and rigidity.
Innovation Solution
A connector socket is designed with a rotatably mounted locking device and a socket housing that is axially movable via a compression spring, eliminating the need for a housing and ensuring a secure, space-saving, and resiliently mounted connection with IP-67 or IP-68 sealing, using a coding groove system to prevent rotation and featuring a semi-cylindrical cover plate for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection is used to lock the connector pairs, then the locking strength is improved, but the sealing reliability deteriorates due to vibration transmission
Solution Approach 1:
The connector socket is designed with a resilient mounting system using compression springs that allow dynamic movement and absorption of vibrations. The socket can move axially within the mounting device, converting the rigid connection into a dynamic one that adapts to vibrations while maintaining sealing contact through the resilient support.
2Object-affected harmful factors
If a box with housing wall is used to mount the device socket, then the protection against environment is improved, but the space for large cable cross-sections deteriorates
Solution Approach 1:
The invention extracts the sealing function from the housing wall interface and relocates it to sealing elements integrated directly into the connector socket. This eliminates the need for a separate protective box with housing walls, freeing up space while maintaining environmental protection through the socket's own sealing mechanism.
3Reliability
If a seal is arranged between the connector and housing wall with resilient support, then the sealing reliability is improved, but the vulnerability to dirt penetration deteriorates due to movement
Solution Approach 1:
The invention introduces sealing elements as intermediary components between the connector socket and the external environment. These sealing elements are integrated into the socket structure itself, creating a reliable barrier against dirt and moisture without requiring contact with the housing wall, thus eliminating the dirt penetration issue while maintaining sealing reliability.
