Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of multiple HF coaxial connectors on a printed circuit board is complex and expensive due to the need for precise alignment and positioning of soldering pins and surfaces, which complicates the electrical and mechanical contacting process.
Innovation Solution
A multiple printed circuit board connector design that decouples the plug-in function from the electrical contacting, using a mounting part with separate contact devices to establish electrical contact, allowing for easier alignment and assembly, and featuring a clamping contact with nickel-coated surfaces for high-frequency applications and solderable tin surfaces for reliable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple HF coaxial connectors are integrated into one component with a connector strip, then the quantity of connectors is increased, but the alignment precision requirement for soldering pins and surfaces increases
Solution Approach 1:
The connector is divided into separate contact parts that can be inserted into the mounting part individually. Each contact part contains contact elements that make electrical contact with conductors on the printed circuit board. This segmentation allows each contact part to be positioned independently, reducing the overall alignment precision requirements compared to integrating all connectors into a single rigid connector strip.
Solution Approach 2:
The mounting part serves as an intermediary component between the contact parts and the printed circuit board. It provides a structure with openings for inserting contact parts and establishes electrical connections between the contact elements and the circuit board conductors. This intermediary structure simplifies the assembly process by decoupling the alignment requirements of the contact parts from the circuit board mounting holes.
2Reliability
If soldering pins are precisely aligned to reach into mounting holes simultaneously, then reliable electrical contact is achieved, but the assembly complexity increases
Solution Approach 1:
The electrical contact function is segmented into two separate mechanisms: mechanical insertion of contact parts into the mounting part, and separate soldering of contact elements to circuit board conductors. This segmentation allows each contact element to be soldered independently to its corresponding conductor, eliminating the need for simultaneous alignment of multiple soldering pins with mounting holes, thus reducing assembly complexity while maintaining reliable electrical contacts.
3Reliability
If contact elements directly make electrical contact with conductors on the printed circuit board, then the electrical connection is established, but the positioning precision requirement increases
Solution Approach 1:
The mounting part acts as an intermediary that receives the contact parts and provides a structured interface for electrical connection. The contact elements make electrical contact with conductors on the printed circuit board through this intermediary structure, which compensates for positioning tolerances. This allows the contact elements to be positioned with lower precision while still achieving reliable electrical connections through the mounting part's design.
