Coaxial Plug Axial Slots Pivoting Latching Fork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing BNC coaxial plug connections with bayonet fittings allow free rotation, making it difficult to establish additional electrical connections between probe heads and instruments, leading to compatibility issues between different manufacturers' devices.
Innovation Solution
A coaxial plug design featuring axial slots and a pivoting latching fork with inclined surfaces, ensuring a secure, non-rotating connection to a BNC socket by locking BNC pins between the slots and tines, allowing automatic latching and preventing twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a BNC coaxial plug with bayonet fitting is used, then the plug can be easily connected to the socket, but the plug can rotate freely relative to the socket, preventing reliable additional electrical connections
Solution Approach 1:
The invention transitions from a static bayonet fitting to a dynamic latching mechanism. The latching fork can pivot between a locking position (where latching tines cover axial slots to prevent rotation) and a release position (where axial slots are free for insertion). This dynamic element allows the connection to be easily made while preventing rotation once connected.
Solution Approach 2:
The latching fork acts as an intermediary element between the plug housing and the BNC pins. It mediates the connection by providing the locking function through its tines engaging with the axial slots, thereby preventing rotation while maintaining the ease of connection provided by the axial insertion path.
2Reliability
If an interlock is provided between housings to prevent rotation, then connection orientation is fixed, but the housing forms must be individually matched, increasing device complexity
Solution Approach 1:
The invention extracts the locking function from the housing structure and places it in the latching fork, which is part of the plug assembly. This allows the housing forms to remain simple and universal while the latching fork provides the orientation stability. The locking mechanism is taken out of the housing matching requirements and integrated into the plug's connection mechanism.

AI summary
The invention relates to a coaxial plug for connecting to a high-frequency transmission line. The housing of the coaxial plug has two slits arranged opposite each other, extending from the plug-side end in the axial direction, and both arranged and designed to form an axial abutment for receiving a BNC pin. A latching fork is arranged on the housing with two latching prongs tangentially overlapping an axial slit of the housing between the abutment and the plug-side end. Each BNC pin is held between a latching prong and an abutment of the axial slit, creating a locked connection between the coaxial plug and the BNC coaxial socket. The latching fork is pivotably arranged between a locking position in which the latching prongs tangentially overlap the axial slits, and a clearing position in which the latching prongs clear the axial slits over the entire length thereof.
