Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-on RF connectors fail to maintain signal integrity under harsh environments and vibrations, leading to unintentional de-mating and signal loss, particularly in high-frequency applications.
Innovation Solution
A push-on electrical connector system with a bayonet pin and blind latch track configuration, utilizing a resilient member to ensure positive locking and constant alignment of connector halves, maintaining signal integrity even under tensile forces and vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional push-on RF connectors are used, then the connector size is small and installation is easy, but the connector becomes loose or de-mates under vibration and harsh environments
Solution Approach 1:
The connector is divided into two functional segments: the push-on electrical connection segment for signal transmission and the bayonet locking segment for mechanical retention. This segmentation allows each segment to optimize its specific function while working together as a unified connector system.
Solution Approach 2:
The invention merges two previously separate connection methods (push-on friction fit and bayonet locking) into a single integrated connector system. The bayonet locking mechanism is combined with the push-on electrical interface, allowing both easy installation and secure retention under vibration.
2Ease of manufacture
If friction-fit or snap-on mating is used, then the connector can be easily assembled, but signal integrity is compromised under tensile strain and vibration
Solution Approach 1:
The bayonet locking mechanism performs a preliminary mechanical securing action before the push-on electrical connection is fully engaged. This preliminary locking action pre-establishes mechanical retention, preventing de-mating under subsequent tensile strain or vibration that might otherwise compromise signal integrity.
Solution Approach 2:
The resilient member provides beforehand cushioning by maintaining constant contact pressure between the push-on components. This continuous cushioning force compensates for dimensional variations and prevents loss of electrical contact under vibration, thereby maintaining signal integrity.
3Reliability
If a locking mechanism is added to push-on connectors, then connection stability under vibration improves, but the device complexity increases
Solution Approach 1:
The locking function is extracted as a separate bayonet mechanism distinct from the push-on electrical connection. This extraction allows the locking mechanism to be optimized for reliability while the push-on portion remains simple for easy assembly, with both functions integrated in the final connector design.
Solution Approach 2:
The bayonet locking mechanism serves multiple functions: it provides mechanical retention under vibration, guides alignment during assembly, and works in conjunction with the resilient member to maintain constant contact. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in overall device complexity.

AI summary
A push-on connector system includes a male push-on bore with conductor pin and a female push-on core with socket. A second bore is configured forwardly of the male push-on bore, and a latch track is positioned in the second bore and forms at least one, and preferably a plurality of, inclined latch surfaces. A movable collar mounted rearwardly of the female push-on core includes at least one, and preferably a plurality of pins. The movable collar is configured for engaging the second bore, and is rotatable and axially slidable. The pins slide along the inclined latch surfaces to axially drive the movable collar into the second bore. A resilient member is coupled between the movable collar and female push-on core to bias the female push-on core into the male push-on bore.
