Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire to board connectors with horizontal connection structures require a large mounting area, making them unsuitable for substrates with small sizes.
Innovation Solution
A vertical connection type electrical contact terminal with a horseshoe-shaped design, featuring support and connection plates that allow for a reduced mounting area, enabling easy application to small substrates by bending both ends of a back plate and forming a wire insertion space with locking and elastic portions for secure wire connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a horizontal connection structure is used, then the wire can be easily inserted and connected, but the mounting area becomes large
Solution Approach 1:
The patent transitions from a horizontal connection structure to a vertical connection structure by changing the orientation of the contact terminal. The terminal is designed to stand upright on the substrate with the wire insertion port facing upward, allowing wire insertion in the vertical direction. This dimensional change reduces the mounting area footprint while maintaining ease of wire insertion and connection.
2Area of stationary object
If the mounting area is reduced for small substrates, then the connector becomes suitable for compact devices, but the wire connection stability may be compromised
Solution Approach 1:
The patent employs parameter changes in the connection plate design, specifically the locking portion geometry with interior angles between 65° and 80°, and the two-step bending structure. These parameter optimizations ensure that the wire is securely locked with sufficient retention force while maintaining a compact mounting area suitable for small substrates.
Solution Approach 2:
The contact terminal features a horseshoe shape formed by bending both ends of the back plate toward the front surface. This curved geometry allows the terminal to achieve a compact form factor while maintaining structural integrity and secure wire locking capability, resolving the contradiction between small mounting area and connection stability.
3Area of stationary object
If a vertical connection structure is adopted, then the mounting area is reduced, but the structural complexity increases
Solution Approach 1:
The contact terminal is segmented into distinct functional portions: support plates for mounting on the substrate, connection plates for wire locking, and specific bending portions for structural integrity. This segmentation allows each component to perform its function efficiently while maintaining overall structural simplicity despite the vertical configuration.
Solution Approach 2:
The patent merges multiple functions into the single contact terminal structure: the back plate provides support and forms the horseshoe shape, the support plates enable substrate mounting, and the connection plates perform wire locking. This integration reduces the number of separate components needed, offsetting the increased structural complexity with functional consolidation.
