Quick-Connection Electrical Connector with Bayonet Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for ceiling or wall installations are complex to install and do not ensure a reliable electrical connection over time, particularly for devices like lighting fixtures.
Innovation Solution
A quick connection device featuring a female socket installed in a wall support with a male plug that engages removably, using a bayonet fixing system and an electrical conductor to securely connect an electrical device, where the male plug and conductor are separate elements, and the second electrical connector presses on a shoulder to take up the device's weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet fitting connector is used to attach electrical devices to the ceiling, then the connection can be securely fixed, but the installation becomes complicated requiring multiple components and steps
Solution Approach 1:
The patent combines the electrical conductor and the male plug into a single integrated unit. The conductor is embedded within the male plug body, eliminating the need for separate connection of these components. This merging reduces the number of installation steps while maintaining the secure bayonet fitting connection, thereby resolving the contradiction between connection reliability and installation complexity.
2Reliability
If plugs are secured with screws to guarantee reliable electrical connection, then the electrical connection can be secured, but the installation and removal process becomes time-consuming and complex
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with a bayonet fitting system. The bayonet fitting uses a rotational locking mechanism instead of threaded screws, allowing for quick insertion and secure locking without requiring threading or tightening operations. This substitution maintains electrical connection reliability while dramatically reducing installation and removal time.
3Ease of manufacture
If the male plug and electrical conductor are separate elements, then the components can be manufactured independently, but the installation process becomes more complex requiring multiple connection steps
Solution Approach 1:
The patent merges the male plug and electrical conductor into a single integrated component. The conductor is embedded within the male plug body during manufacturing, creating a pre-assembled unit. This integration maintains the manufacturing flexibility advantage while eliminating the need for separate connection steps during installation, thereby reducing installation complexity.

AI summary
The invention relates to a quick-connection device comprising: - a female jack forming an electrical socket, the female jack comprising a cavity receiving a first electrical connector connected to an electrical grid; - a male plug comprising a second electrical connector and having a shape matching that of the cavity of the female jack, it being possible for the male plug to go from an unlocked position in which the male plug can be inserted into the female jack to a locked position in which the male plug is firmly attached to the female plug and the second electrical connector cooperates with the first electrical connector; - an electrical conductor extending inside the male plug. According to the invention, the second electrical connector comprises means arranged to carry the weight of the electrical device.
