Plug Contact With Oblique Sealing Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug-in contacts are limited in their ability to securely connect in both axial and transverse directions, particularly at right angles, and often require different constructions for each orientation, lacking adequate tightness in both configurations.
Innovation Solution
The design features a first contact part with a tongue-shaped profile and a second contact part that can be attached transversely or at an angle, with both contact parts surrounded by housings having obliquely arranged sealing surfaces and lead-in surfaces to ensure secure engagement and sealing, allowing for axial and perpendicular connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the contact parts are designed for axial connection only, then the connection is simple and secure, but the device cannot be used for transverse or angled connections requiring different constructions
Solution Approach 1:
The contact part design incorporates a universal housing structure with sealing surfaces and lead-in surfaces that enable the same component to be used for axial, transverse, and angled connections. The housing with oblique sealing surfaces and integrated seal allows a single construction to fulfill multiple connection orientations, eliminating the need for different constructions for different applications.
2Adaptability or versatility
If the contact parts are designed for transverse connection, then versatile positioning is achieved, but adequate tightness and sealing are difficult to ensure
Solution Approach 1:
The housing is designed with localized sealing features including oblique sealing surfaces arranged at specific angles and integrated seals positioned at critical interfaces. These localized quality enhancements ensure adequate tightness and sealing specifically at the connection interfaces where it is most needed, while maintaining the overall versatility of the contact part design.
3Reliability
If sealing surfaces are arranged obliquely at 45 degrees, then tightness and sealing are significantly improved, but the manufacturing complexity increases
Solution Approach 1:
The sealing surfaces are arranged obliquely at a specific angle parameter (45 degrees) to optimize sealing performance. This parameter change improves tightness by creating optimal contact geometry, while the angle is chosen as a standard value that balances manufacturing feasibility with sealing effectiveness.
4Ease of operation
If lead-in surfaces are added to facilitate attachment, then ease of connection is improved, but the device complexity increases
Solution Approach 1:
Lead-in surfaces are incorporated into the housing design to guide and facilitate the attachment process. These pre-formed surfaces perform the preliminary action of guiding the mating contact part into proper alignment and position, making the connection process easier while the features are integrated into the overall housing structure.

AI summary
The invention relates to a plug contact having at least one first contact part and at least one second, wherein one contact part may be overlapped by the other contact part and, in a plugged-together position, the two contact parts are aligned with one another, and wherein, in a second plugged-together position, the second contact part may be plugged into, particularly is plugged into, the first contact part transversely or obliquely to the insertion direction of the first position.
