PCB Through-Hole Connector Layout for Faster Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of mounting connectors on printed circuit boards is time-consuming and costly due to the need for double processes, where connectors are mounted on the lower surface after components are mounted on the upper surface, increasing the complexity and cost of electrical connections.
Innovation Solution
A connector is mounted on the upper surface of a printed circuit board with through-holes, allowing it to provide electrical connections between the upper and lower surfaces, and includes terminals to connect adjacent portions of the board, simplifying the connection configuration and reducing the need for complex vias.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is mounted on the lower surface of the printed circuit board after components are mounted on the upper surface, then the electrical connection between upper and lower surfaces is achieved, but the process time and manufacturing cost increase due to double mounting processes
Solution Approach 1:
The patent combines the connector mounting process with the component mounting process by mounting both on the upper surface of the printed circuit board simultaneously. The connector includes terminals that extend through the board to provide electrical connections, eliminating the need for separate upper and lower surface mounting operations. This merging of operations reduces process time while maintaining reliable electrical connectivity.
2Reliability
If the connector is mounted on the lower surface of the printed circuit board, then the electrical connection is established, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent inverts the conventional mounting approach by mounting the connector on the upper surface of the printed circuit board instead of the lower surface. The connector terminals extend through the board to establish electrical connections, simplifying the overall connection configuration and reducing manufacturing complexity while maintaining reliable electrical connectivity between components.

AI summary
A display apparatus includes a display panel, a printed circuit board defining an upper surface, a lower surface opposite the upper surface, and a through-hole, a plurality of light sources mounted on the upper surface of the printed circuit board and configured to emit light to the display panel, and a connector inserted into the through-hole on the upper surface of the printed circuit board. The connector includes a connector body inserted into the through-hole, and a plurality of connector terminals disposed in proximity to the upper surface of the printed circuit board. The connector terminals are configured to electrically connect the connector body to a portion of the printed circuit board, and may in certain embodiments connect a first portion of the printed circuit board on one side of the connector body to a second portion of the printed circuit board on an opposite of the connector body.
