Angled Connector Housing Ring Seal Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assembling angled electrical connector housings can be cumbersome and may damage the seal due to the angled arrangement of the electrical contact and cable, leading to ineffective sealing.
Innovation Solution
A connector housing design featuring a contact housing member and a cable housing member with a ring seal that has inclined second portions and perpendicular first sealing surfaces, allowing for easy assembly and even pressure distribution to achieve effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the contact housing member and cable housing member are assembled along an assembly direction with an angled arrangement, then the electrical connector achieves its angled functionality, but the seal may become damaged during assembly
Solution Approach 1:
The ring seal is divided into two first portions and two second portions, with the second portions being inclined at an angle between 10° and 45° relative to the assembly direction. This segmentation allows different parts of the seal to serve different functions: the first portions provide sealing surfaces perpendicular to the mating direction, while the inclined second portions guide the housing members past each other during assembly, reducing seal damage risk.
Solution Approach 2:
The seal transitions from a simple linear configuration to a three-dimensional structure with inclined portions. The second portions are inclined both in the assembly direction and in a direction perpendicular to the assembly direction, creating a diagonal path that guides the housing members past each other while maintaining sealing effectiveness.
2Device complexity
If the ring seal has second portions extending parallel to the cable direction or assembly direction, then the seal structure is simpler, but the housing members must pass along each other over a longer distance during assembly
Solution Approach 1:
The second portions of the ring seal are inclined not only in the assembly direction but also in a direction perpendicular to the assembly direction. This diagonal arrangement allows the housing members to pass along each other more quickly during assembly, reducing the assembly distance and time while maintaining structural effectiveness.
3Device complexity
If the first sealing surfaces are not perpendicular to the mating direction, then the seal geometry may be simpler, but uniform pressure distribution on the seal during mating is not achieved
Solution Approach 1:
The first portions of the ring seal are specifically configured with first sealing surfaces that extend perpendicular to the mating direction. This local geometric feature ensures that when the connector housing is mated with the mating connector, the force exerted on the housing is distributed evenly across the first portions of the ring seal, achieving uniform pressure distribution at the critical sealing interface.
