Board-to-Board Connector Assembly With Through-PCB Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional board-to-board connector assemblies require a large assembly space due to the overall height of the plug and socket, limiting the ability to reduce the thickness of electronic devices.
Innovation Solution
The board-to-board connector assembly incorporates a plug connector with a first insulating housing and fastening elements, and a socket connector with a second insulating housing and fastening elements, designed to penetrate through the printed circuit boards, allowing for a reduced assembly distance and stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plug and socket are mounted to two facing surfaces of printed circuit boards, then electrical connection is achieved, but assembly distance between boards increases
Solution Approach 1:
The insulating housing is inserted through a penetrating groove in the printed circuit board, with the socket mounted on the housing. This nesting arrangement allows the connector components to be integrated within the board thickness rather than extending outward, reducing the assembly distance between boards while maintaining reliable electrical connection through the terminals.
2Reliability
If plug and socket are mounted on facing surfaces, then electrical connection is established, but overall height of connector assembly increases
Solution Approach 1:
The connector design transitions from a surface-mounted configuration to a through-board configuration. The insulating housing passes through the penetrating groove from one surface to the other, positioning the socket on the opposite side. This dimensional change allows the connector to utilize the board thickness space, reducing the overall height of the assembly while maintaining electrical connectivity.
3Reliability
If conventional board-to-board connector is used, then electrical circuits are connected, but assembly space is occupied
Solution Approach 1:
The insulating housing is inserted through a penetrating groove in the printed circuit board, with the socket mounted on the housing. This nesting arrangement allows the connector components to be integrated within the board thickness rather than extending outward, reducing the assembly distance between boards while maintaining reliable electrical connection through the terminals.
4Reliability
If plug and socket are mounted on facing surfaces, then electrical connection is achieved, but device thickness cannot be reduced
Solution Approach 1:
The connector design transitions from a surface-mounted configuration to a through-board configuration. The insulating housing passes through the penetrating groove from one surface to the other, positioning the socket on the opposite side. This dimensional change allows the connector to utilize the board thickness space, reducing the overall height of the assembly while maintaining electrical connectivity.
