Bayonet Electrical Connector Flush Vehicle Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection systems in vehicle construction, particularly in the luggage area, are inconvenient due to their design and protruding parts, which can cause disruptions and damage when not in use.
Innovation Solution
A bayonet-type connection system with an axial insertion channel and offset locking position, featuring a cover that can be displaced to release the opening for connection, allowing for a secure and low-depth installation that is flush with the surrounding surface, preventing damage and oxidation of electrical contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional electrical connection system is installed in the vehicle trunk, then electrical connection is provided, but the system protrudes and becomes disruptive in the loading area
Solution Approach 1:
The socket is nested into the vehicle body panel, with the cover providing the external interface. The electrical contacts are housed within the socket body, creating a compact nested structure that minimizes protrusion while maintaining full connection functionality.
Solution Approach 2:
The connection system transitions from a protruding three-dimensional structure to a flush-mounted configuration by utilizing the panel thickness dimension. The socket is recessed into the panel, and the cover provides the external interface, effectively moving the bulk of the structure into the panel depth rather than having it protrude outward.
2Productivity
If the socket is left open for easy connection, then connection speed is improved, but electrical contacts are exposed to contamination and oxidation
Solution Approach 1:
The cover is pre-positioned in the closed state, protecting the electrical contacts from contamination and oxidation before connection is needed. The spring mechanism is pre-loaded to automatically push the cover open upon plug insertion, providing immediate protection while enabling rapid connection when required.
Solution Approach 2:
The cover transitions from a static protective barrier to a dynamic element that automatically responds to connection attempts. The spring mechanism enables the cover to move between closed (protective) and open (connection-enabled) states, providing both protection and rapid access without manual intervention.
3Object-affected harmful factors
If a cover is added to protect the socket, then contamination protection is improved, but device complexity increases
Solution Approach 1:
The spring mechanism enables the cover to automatically open when the plug is inserted and automatically close when the plug is removed, without requiring manual operation or additional control systems. The system serves itself by using the connection action to trigger the cover opening and the disconnection action to trigger the cover closing.
4Length of stationary object
If the socket is installed flush with the surface, then aesthetic appearance and space utilization are improved, but the connection mechanism becomes more difficult to implement
Solution Approach 1:
The connection system is segmented into distinct functional components: the cover providing the external interface, the socket body housing the electrical contacts and bayonet mechanism, and the spring mechanism providing automatic cover operation. This segmentation allows each component to be optimized and assembled to achieve the flush-mounted configuration.

AI summary
A connection system, in particular an electrical connection system, having a male connector and having a female connector has a bayonet-type connection for connecting the male connector and the female connector. The bayonet-type connection has at least one axially extending insertion channel and at least one adjoining latching position, which is offset in the circumferential direction with respect thereto, in the female connector, the end side of the female connector, which end side is provided for connection to the male connector, being covered by a cover, which is arranged adjustably in the female connector such that, when the male connector is positioned on it, the opening is released by this male connector in order to produce the connection.
