Bayonet Connector Assembly with Axial Locking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector arrangements for high-frequency applications are either cost-intensive due to the number of parts required or require excessive space, making them unsuitable for modern miniaturization needs, and they often suffer from intermodulation issues and complex assembly processes.
Innovation Solution
A connector assembly utilizing a bayonet-type connection combined with a locking element arranged in the plug-in direction, eliminating the need for additional fixing elements and allowing for minimal dimensioning of connectors, enabling close arrangement and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple auxiliary elements (pins, snap connections, spring elements) are used to secure connectors, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The locking element is integrated directly into the connector body, merging the locking function with the connector structure itself. This eliminates the need for separate auxiliary locking components while maintaining secure connection reliability through the bayonet-type engagement mechanism.
Solution Approach 2:
The connector body serves multiple functions: it provides structural support, electrical connection, and integrated locking capability. The locking element arranged in the plugging direction performs both guidance during insertion and securing in the locked position, combining multiple functions into a single component system.
2Reliability
If a rotating ring is used for securing connectors, then connection reliability is improved, but the space required increases preventing close placement of multiple connectors
Solution Approach 1:
Instead of using a rotating ring that occupies radial space, the locking element is arranged in the plugging direction (axial dimension). This dimensional change allows the locking mechanism to function within the length of the connector rather than requiring additional radial clearance, enabling closer placement of multiple connectors.
Solution Approach 2:
The external rotating ring structure is removed and replaced with an integrated locking element within the connector body. This extraction of the bulky rotating ring component eliminates the space requirement while maintaining the securing function through the bayonet-type connection mechanism.
3Reliability
If locking elements are arranged perpendicular to the plugging direction, then connection reliability is improved, but assembly complexity increases
Solution Approach 1:
Instead of arranging locking elements perpendicular to the plugging direction as in conventional designs, the locking element is inverted to extend in the plugging direction itself. This inversion simplifies the assembly process by aligning the locking action with the insertion motion, allowing automatic engagement during the plugging operation without requiring separate perpendicular alignment steps.
