Electrical Connector Support Ring Double Seal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors lack a robust connection between the housing and the electrical connector, leading to oil leakage due to O-ring displacement and deformation under stress, especially when the connector is used as a handle for transporting equipment.
Innovation Solution
A support ring with a baseplate and sidewall that includes recessed portions for O-rings and gaskets, providing a double seal between the electrical connector and the housing, and preventing O-ring movement into the inner cavity, made from anti-corrosive materials to enhance connection strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional electrical connector is used without a support ring, then the device complexity is reduced, but the connection strength and reliability deteriorate due to O-ring displacement and deformation under stress
Solution Approach 1:
A support ring is introduced as an intermediary component between the electrical connector and the housing. This support ring includes a baseplate with a first side and a second side, a recessed portion on the first side for receiving a primary O-ring, and a sidewall extending from the second side. The support ring mediates the connection by providing a stable mounting structure that prevents O-ring displacement and deformation, thereby enhancing connection strength and reliability without requiring fundamental changes to the existing electrical connector design.
2Ease of operation
If the connector is used as a handle for transporting equipment, then the ease of operation is improved, but the reliability deteriorates due to stress-induced O-ring deformation and leakage
Solution Approach 1:
The support ring provides beforehand cushioning by creating a double seal arrangement with primary and secondary O-rings. The primary O-ring is received in a recessed portion on the first side of the baseplate, while the sidewall extending from the second side provides additional support and prevents O-ring displacement. This preemptive structural support cushions against stress-induced deformation during transportation when the connector is used as a handle, maintaining reliability despite the operational convenience of using the connector as a transport handle.
3Reliability
If a double seal arrangement with primary and secondary O-rings is implemented, then the reliability is improved by reducing leakage, but the device complexity increases
Solution Approach 1:
The support ring merges multiple functions into a single integrated component. It combines the baseplate with the recessed portion for the primary O-ring and the sidewall for secondary O-ring support into one unified structure. This merging approach allows the double seal arrangement to be implemented without proportionally increasing device complexity, as the primary and secondary sealing functions are integrated into a single support ring component rather than requiring separate assemblies.
