Solution Overview
Problem
Existing solutions for connecting strip lamps, such as LED flextape, face issues with inconvenient assembly, poor electrical reliability, and inadequate waterproofing, particularly when soldering is required.
Innovation Solution
A connector for strip lamps using pins with a low thermal expansion coefficient and a fixing unit, along with a sealing part, facilitates easy assembly and ensures good electrical reliability and waterproofing by clamping to solder pads and sealing gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are welded with solder pads and wrapped with a casing, then electrical connection is achieved, but assembly convenience deteriorates and electrical reliability is insufficient
Solution Approach 1:
The patent extracts the soldering process from the connection assembly and replaces it with a mechanical pressing connection. The connector directly presses the conductive part against the solder pad through a pressing element, eliminating the need for soldering while maintaining electrical connection reliability and significantly improving assembly convenience.
Solution Approach 2:
The patent replaces the thermal-mechanical soldering system with a purely mechanical pressing system. The connector uses a pressing element that applies mechanical force to establish electrical contact between the conductive part and solder pad, substituting the soldering process with a mechanical connection method.
2Ease of operation
If wires and solder pads are pressed by external force, then assembly is simplified, but electrical reliability deteriorates and waterproof characteristics are lost
Solution Approach 1:
The patent employs a nested structure where the conductive part, pressing element, and sealing element are housed within the connector body. The sealing element is integrated into the connector and wraps around the pressing element and conductive part, creating a nested configuration that protects the electrical connection while maintaining assembly convenience.
Solution Approach 2:
The patent introduces a sealing element as an intermediary component between the electrical connection and the external environment. This sealing element fills the gap between the strip lamp and connector, preventing water ingress while allowing the mechanical pressing connection to function, thus simultaneously achieving both assembly convenience and electrical reliability with waterproofing.
3Ease of operation
If a connector without sealing is used, then assembly is simple, but waterproof characteristics are insufficient
Solution Approach 1:
The patent uses a flexible sealing element that can deform to fill the gap between the strip lamp and connector. This flexible sealing component provides waterproof protection while maintaining the simplicity of assembly, as the sealing element is integrated into the connector and automatically seals the gap when the connector is assembled.

AI summary
A connector for a strip lamp and a strip lamp assembly. At least two pins for connecting to solder pads of a strip lamp and at least one fixing unit with a coefficient of thermal expansion less than a predetermined threshold are used in the connector. Therefore, it is convenient for users to assemble different lengths of strip lamps according to actual requirements, and a good electrical reliability is achieved. In addition, a sealing part for sealing a gap between the strip lamp and the connector is applied in the strip lamp assembly, thus good waterproof characteristics are achieved.
