Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electrical connectors are mounted back to back on circuit boards, then space utilization is improved, but system structure complexity increases and mounting difficulty worsens
Solution Approach 1:
The press-fit portions are arranged in alternating rows with staggered positions, creating an asymmetric mounting pattern that reduces interference between adjacent connectors while maintaining compact space utilization
Solution Approach 2:
The press-fit portions are distributed across multiple rows (first row and second row) in parallel arrangements, utilizing the vertical dimension to reduce interference while maintaining compact footprint on the circuit board
2Ease of manufacture
If press-fit portions are arranged in a single row, then manufacturing is simplified, but interference between adjacent connectors increases
Solution Approach 1:
The press-fit portions are arranged in multiple parallel rows instead of a single row, utilizing the vertical dimension to separate adjacent press-fit portions and reduce interference while maintaining manufacturing simplicity
Solution Approach 2:
The mounting structure is segmented into multiple rows of press-fit portions, with each row containing alternating press-fit portions, reducing the density and interference in any single location
3Quantity of substance
If conventional mounting structures are used, then component count is maintained, but mounting convenience and time increase
Solution Approach 1:
The electrical connector integrates multiple functions into a single component: conductive terminals for electrical connection, press-fit portions for mechanical mounting, and positioning structures for alignment, all combined in one integrated assembly that simplifies mounting operations
Solution Approach 2:
The connector features self-aligning and self-mating capabilities through the positioning structures and mating slots, allowing the connector to automatically position itself during mounting without requiring additional alignment fixtures or procedures

AI summary
An electrical connector includes an insulating body, a number of first conductive terminals and a number of second conductive terminals. Each first conductive terminal includes a first mating arm. Each second conductive terminal includes a second mating arm and a second press-fit portion for being mounted to a circuit board. Among the second conductive terminals, the second press-fit portions corresponding to any two adjacent second mating arms are disposed alternately along a second arrangement direction of the second mating arms. Therefore, it effectively avoids the mutual influence between the second press-fit portions, and facilitates the realization of the installation with the circuit board. The present disclosure also discloses an electrical connector assembly having the electrical connector.
