Linear Lighting Connector with Pivoting Joint and Strain Relief Ramps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for linear lighting face issues such as strain induction and non-uniform light output due to raised slots, and lack the ability to connect strips at angles, with existing solderless connectors not providing adequate strain relief or allowing for pivoting connections.
Innovation Solution
The development of a connector with a pivoting joint and ramps for strain relief, featuring conductive contact members that can connect to both linear lighting strips and wires, allowing for angle adjustments and reducing strain through a sloped design that minimizes 'hot spots' in light output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If linear lighting is connected using traditional soldering, then reliable electrical connection is achieved, but the installation process becomes complex and requires skilled technicians
Solution Approach 1:
The patent replaces the mechanical soldering process with a spring-loaded contact system. The spring mechanism automatically applies pressure to maintain electrical contact without requiring soldering skills, thus maintaining reliability while greatly simplifying installation. The spring contactor engages with the PCB trace through simple insertion, eliminating the need for heated tools and skilled labor.
Solution Approach 2:
The connector design allows the linear lighting strip to insert itself into the connector housing, with the spring mechanism automatically engaging the PCB trace. This self-service insertion process eliminates the need for skilled technicians to perform complex soldering operations, while the spring ensures reliable electrical connection is achieved automatically.
2Reliability
If a raised slot is used to receive linear lighting in connectors, then electrical connection is achieved, but strain is induced in the lighting strip causing non-uniform light output
Solution Approach 1:
The patent introduces a ramp structure that creates a gradual transition from the connector housing level to the PCB level. This ramp extends in the horizontal dimension, allowing the linear lighting strip to slope down gradually rather than making an abrupt vertical transition. This dimensional change eliminates strain on the lighting strip while maintaining reliable electrical connection through the spring mechanism.
Solution Approach 2:
The ramp structure serves as a cushioning element that预先 (in advance) compensates for the height difference between the connector housing and the PCB. By providing this gradual transition beforehand, the design prevents strain from developing in the linear lighting strip, thus avoiding non-uniform light output while ensuring proper electrical connection.
3Device complexity
If connectors provide linear end-to-end connections, then simple connection structure is achieved, but flexibility in positioning is limited
Solution Approach 1:
The patent incorporates a pivoting mechanism that allows the connector to rotate relative to the PCB. This dynamic feature enables the linear lighting strip to be positioned at various angles while maintaining electrical connection through the spring contactor. The pivot joint provides mechanical flexibility without significantly increasing structural complexity, as it uses a simple hinge-like mechanism.
