Multi-Layer Connector With Angled Ports For Slim Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-layer connectors in electronic devices face interference issues due to external terminals being inserted in the same direction, leading to increased device thickness and usability challenges, while single-layer connectors require larger PCBs for multiple connections.
Innovation Solution
A multi-layer connector design where external terminals are inserted at different angles, specifically a first port parallel to the PCB and a second port layered at an angle, minimizing interference and optimizing usability without increasing device thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a multi-layer connector is used to connect multiple external terminals, then the PCB size can be kept small, but the electronic device becomes thicker and external terminals may interfere with each other during insertion
Solution Approach 1:
The patent applies dimensionality change by transitioning from a single-layer planar arrangement to a multi-layer stacked configuration. Multiple ports are arranged in different layers (first layer and second layer) with different insertion directions, allowing multiple external terminals to be connected without increasing PCB area while avoiding interference through spatial separation in the thickness direction
2Length of stationary object
If external terminals are inserted in the same direction in a multi-layer connector, then the device thickness can be minimized, but the external terminals interfere with each other during insertion and removal
Solution Approach 1:
The patent applies asymmetry by configuring different insertion directions for ports in different layers. The first port has a first insertion direction and the second port has a second insertion direction that is different from the first, creating an asymmetric arrangement that prevents external terminals from interfering with each other during insertion and removal operations
3Ease of operation
If a single-layer connector is used to connect multiple external terminals, then insertion interference is avoided, but the PCB size increases significantly
Solution Approach 1:
The patent applies the nesting principle by stacking multiple port layers within a compact vertical space. The first port and second port are nested in different layers, with the second port positioned above or below the first port, allowing multiple connections to be integrated in a small PCB area while maintaining ease of operation through different insertion directions

AI summary
A connector that is configured to be installed on a printed circuit board (PCB) and electrically connected to an external terminal is provided. The connector may include a first port that is disposed on the PCB and is configured to accept a first external terminal into the first port in a first direction, and a second port that is layered on top of the first port and is configured to accept a second external terminal into the second port in a second direction that is formed at an angle from the first direction.
