Dual-PCB Electrical Connector Housing for Stable Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual board electrical connectors face challenges with poor component positioning and inconvenient assembly due to the need to align and install circuit boards relative to each other, which can lead to instability and easy dislodging during assembly.
Innovation Solution
The design includes a casing with protruded carrying platforms and holder blocks on both the inner bottom and top surfaces, along with positioning pins and notches on the circuit boards, allowing for independent alignment and secure clamping of each circuit board within the connector, facilitating easier assembly and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If circuit boards are installed into half shells separately and then combined, then assembly can be performed in steps, but the circuit boards cannot be positioned properly and may fall off easily
Solution Approach 1:
The patent applies preliminary action by pre-installing positioning pins on the first half shell before assembling the circuit boards. These positioning pins are prepared in advance to guide and secure the circuit boards during assembly, preventing them from falling off when the half shells are combined. This preliminary preparation ensures both ease of assembly and reliable component positioning.
2Ease of operation
If one half shell is installed upside down during assembly, then the two half shells can be combined, but the circuit board in that half shell may fall off easily
Solution Approach 1:
The patent applies asymmetry by making the two half shells non-identical in structure. The first half shell includes positioning pins while the second half shell does not, creating an asymmetric design. This allows the assembly to be performed with one half shell in a specific orientation (upright position with positioning pins), eliminating the need to install any half shell upside down and preventing circuit boards from falling off during assembly.
3Manufacturing precision
If precise alignment of circuit boards is required during assembly, then proper positioning can be achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent applies self-service through self-aligning features where the positioning pins on the first half shell automatically guide the circuit boards into correct positions during assembly. The circuit boards have corresponding positioning structures that mate with these pins, enabling automatic alignment without requiring manual precision or complex alignment procedures. This self-aligning mechanism achieves precise positioning while keeping the assembly process simple and efficient.

AI summary
An electrical connector includes a casing, and a first and a second circuit boards. The casing has a bottom shell and a cover. The bottom shell has an inner bottom surface and an open top. A first carrying platform and a second carrying platform protruded from the inner bottom surface. The cover has an inner top surface facing the inner bottom surface. A first and a second holder blocks are protruded from the inner top surface. The first circuit board is carried on the first carrying platform and clamped between the first carrying platform and the first holder block. The second circuit board is carried on the second carrying platform, stacked on the first circuit board, and clamped between the second carrying platform and the second holder block. The second circuit board has an opening for the first holder block to pass.
