Plate-like Cable Connector for LED Light Path Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors interrupt light beams emitted by LEDs on a board, reducing the amount of outgoing light due to their design, which obstructs both horizontal and obliquely upward optical paths.
Innovation Solution
A connector with a plate-like mounting portion and a cable fitting portion that protrudes from the board, allowing the cable to pass through a through hole, minimizing the connector's height and avoiding obstruction of light paths, while ensuring secure electrical connection and easy insertion of coated conductors using bending and projecting portions to prevent deformation and facilitate insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector is mounted on the board, then electrical connection is achieved, but light beams emitted by LEDs are interrupted and the amount of outgoing light is reduced
Solution Approach 1:
The connector body is designed with a plate-like shape that protrudes in the thickness direction (vertical dimension) rather than extending in the horizontal plane. This dimensional change allows the connector to occupy vertical space without blocking horizontal light paths from LEDs, resolving the contradiction between maintaining electrical connection reliability and preserving illumination intensity.
2Illumination intensity
If the connector height is reduced to minimize light obstruction, then light paths are preserved, but structural stability and electrical connection reliability may be compromised
Solution Approach 1:
The connector is segmented into distinct functional portions: a plate-like body for mounting stability, a cable receiving portion for cable management, and contact portions for electrical connection. This segmentation allows each portion to be optimized independently - the plate-like body provides structural stability with minimal height, while the cable receiving portion ensures reliable electrical connection without compromising overall stability.
3Ease of manufacture
If the connector structure is simplified to reduce manufacturing cost, then production efficiency increases, but resistance to external forces and deformation may decrease
Solution Approach 1:
The connector integrates multiple functions into a single unified structure: the plate-like body serves as both the mounting base and structural support, while incorporating the cable receiving portion and electrical contacts. This merging of functions reduces the number of separate components needed, simplifying manufacturing and reducing costs, while the integrated design maintains structural integrity and resistance to external forces.

AI summary
A connector has a mounting portion of a plate-like shape and a cable fitting portion protruding from the mounting portion in a first direction. The mounting portion has a fixing portion disposed on a first flat surface faced to the first direction and adapted to be fixed to a board, and a flat portion disposed on a second flat surface faced to a second direction opposite to the first direction. The cable fitting portion has a receiving portion adapted to receive a cable, an opening portion formed at one end of the receiving portion and allowing the cable to be inserted therethrough, and a cable contact portion to be electrically connected to the cable.
