Solution Overview
Problem
Conventional connectors for circuit boards in unit wiring racks are inefficient in using space and have complex mounting structures, limiting the number of electrical terminals that can be supported in miniaturized systems.
Innovation Solution
A connector design featuring a connector body with a housing portion and a base portion, a panel with aperture portions, a turn axis member, and a connecting member that integrates with the panel and frame, allowing for reduced component count and simplified assembly, enabling more efficient use of space and supporting a higher number of electrical terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional connector structures with separate attachment portions are used, then the connector can be assembled with the circuit board, but the space utilization on the circuit board edge is inefficient and the mounting structure becomes complicated
Solution Approach 1:
The patent combines the connector body and base portion into a single integrated structure, eliminating the need for separate attachment portions. The connector body (53) and base portion (514) are formed as one piece, which simplifies the mounting structure and reduces the number of components required for assembly with the circuit board.
Solution Approach 2:
The base portion (514) serves multiple functions: it provides structural support for the connector body, acts as a mounting platform for attaching the connector to the circuit board, and extends to facilitate alignment and connection. This multi-functional design reduces the need for additional separate components.
2Quantity of substance
If conventional connector terminal sizes and inter-terminal distances are used, then the connector can be assembled on the circuit board, but the number of electrical terminals that can be supported is limited due to miniaturization requirements
Solution Approach 1:
The patent optimizes the spatial arrangement of electrical terminals by utilizing the vertical dimension and angular orientation. The connector body is positioned at an angle relative to the circuit board edge, allowing terminals to be arranged in a configuration that maximizes the number of terminals within the limited edge space without increasing the inter-terminal distance horizontally.
Solution Approach 2:
The patent changes the geometric parameters of the connector arrangement, specifically the angle of insertion and the orientation of the connector body relative to the circuit board. This allows for more efficient packing of electrical terminals along the circuit board edge, increasing the terminal density without compromising signal integrity or assembly feasibility.
3Productivity
If separate attachment portions are used for the connector and ejector, then each component can be assembled independently, but the overall assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent integrates the connector body and base portion into a single component that can be attached to the circuit board as one unit. This eliminates the need for separate attachment operations for the connector and its mounting structure, thereby simplifying the assembly process and improving productivity.
