Panel-Mounted Connector Assembly for Precise PCB Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors in laser radar systems lack positioning structures, leading to inaccurate relative positioning between the connector and the circuit board, which can affect electrical connections and potentially cause failures.
Innovation Solution
A connector assembly with a housing mounted on a mounting panel, featuring a base with a first positioning post for alignment with a panel hole and a tongue extending through the panel to connect to a circuit board, along with a second positioning post on the panel for circuit board alignment, ensuring precise positioning and secure electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector is mounted on a mounting panel without positioning structures, then the installation flexibility is improved, but the positioning accuracy between the connector and circuit board deteriorates
Solution Approach 1:
The positioning function is segmented from the mounting panel and implemented through separate positioning posts and positioning holes. The positioning posts protrude from the mounting panel surface and engage with corresponding positioning holes in the circuit board, creating a dedicated positioning mechanism that operates independently from the mounting structure.
Solution Approach 2:
Positioning posts and positioning holes serve as intermediary elements between the mounting panel and the circuit board. These intermediaries transmit and maintain the precise relative position between the connector and circuit board, ensuring accurate alignment without requiring direct integration into the mounting panel structure.
2Device complexity
If no positioning structure is provided between the connector and circuit board, then the device complexity is reduced, but the electrical connection reliability deteriorates
Solution Approach 1:
The positioning function is divided into separate components (positioning posts and positioning holes) rather than integrating a complex positioning mechanism into the connector housing. This segmentation maintains simplicity while ensuring reliable positioning and electrical connection.
Solution Approach 2:
The positioning posts and holes automatically align the connector with the circuit board during installation. The mechanical engagement of these simple features self-regulates the positioning without requiring additional adjustment mechanisms or complex alignment procedures.

AI summary
A connector comprises a housing adapted to be mounted on a mounting panel and a terminal fixed within the housing. The housing includes a body, a base formed on a bottom of the body and a tongue protruding from the bottom of the base. The base is adapted to be fixed on one side of the mounting panel. A first positioning post is formed on the base for mating with a first positioning hole formed in the mounting panel to locate the housing at a predetermined position with respect to the mounting panel. The tongue is adapted to pass through an installation opening formed in the mounting panel to connect a circuit board.
