Light Source Connector Eliminates Wiring in Backlight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector structures for light source modules in liquid crystal display backlight assemblies are complex, leading to increased manufacturing costs and reduced reliability due to electrical interference and peeling of connecting wiring sheaths.
Innovation Solution
A connector design that directly receives portions of both the light source module and the light source driver, eliminating the need for connecting wirings, with a body portion featuring first and second opening portions for receiving these components and terminal portions for electrical connection, thereby simplifying the connecting structure and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting wirings are used to connect the light source module to the driving circuit part, then electrical connection can be established, but the assembly process becomes complicated and manufacturing cost increases
Solution Approach 1:
The connector integrates multiple functions into a single component: the light source module is directly coupled to the connector body, eliminating separate connecting wirings and fixing structures. The terminal portion of the connector directly contacts both the light source module and driving circuit part, merging the connection function into one integrated structure that simplifies assembly while maintaining reliable electrical connection.
2Reliability
If fixing elements such as tape and fixing structure are used to fix the connecting wirings, then the wirings can be secured, but manufacturing cost increases
Solution Approach 1:
The invention extracts and eliminates the need for separate fixing elements (tape, fixing structures) by integrating the fixation function directly into the connector body. The light source module is fixed to the connector body through the integrated structure itself, removing the need for additional fixing components and reducing manufacturing cost while maintaining secure fixation.
3Reliability
If connecting wirings are used, then electrical connection can be established, but electrical interference may be caused between the wirings
Solution Approach 1:
The connector acts as an intermediary structure that provides direct contact between the light source module and driving circuit part. This intermediary design eliminates the need for exposed connecting wirings that could cause electrical interference, while the terminal portion ensures stable electrical connection through direct contact surfaces within the protected connector structure.

AI summary
A connector for a light source module includes a body portion and a terminal portion. The body portion includes a first opening portion and a second opening portion. The first opening portion receives a portion of the light source module. The second opening portion receives a portion of a light source driver which drives the light source module. The terminal portion includes a first terminal and a second terminal. The first terminal is in the first opening portion of the body portion. The second terminal is connected to the first terminal. The second terminal is in the second opening portion of the body portion.
