Solution Overview
Problem
Existing edge mount coaxial cable connectors often suffer from instability when assembled on circuit boards, leading to issues like skewing, detachment, and increased assembly time and costs due to the need for additional tools to secure the connector.
Innovation Solution
A connector design featuring a body with a mandrel and at least three supporting rods, where the supporting rods are arranged parallel to the circuit board and include an elastic part that deforms to securely attach the connector to the board, reducing the need for additional tools and ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector is assembled on a circuit board with tolerance gaps, then the connector body can be installed, but the connector becomes inclined and unstable
Solution Approach 1:
The connector body is divided into multiple supporting rods (at least three) that are distributed across the circuit board surface. Each supporting rod independently contacts the board, distributing the mounting stress and preventing inclination even when tolerance gaps exist between the connector and board.
Solution Approach 2:
The supporting rods extend from the connector body toward the circuit board, utilizing the vertical dimension to bridge the tolerance gap. By having rods contact the board at multiple points below the main connector body, the design compensates for horizontal misalignment and maintains stability.
2Stability of the object's composition
If additional tools are used to fix the connector to the circuit board, then the connector stability is improved, but the operating time and cost increase
Solution Approach 1:
The elastic parts on the supporting rods provide self-adjusting contact with the circuit board. When the connector is placed on the board, the elastic parts automatically deform to accommodate tolerance variations and secure the connector in position without requiring external fastening tools.
Solution Approach 2:
The elastic parts change their physical state (deformation) in response to contact with the circuit board. This parameter change allows the supporting rods to adapt to the board surface, maintaining stable contact and eliminating the need for additional fixation tools.
3Reliability
If the connector is secured with additional tools, then the detachment risk is reduced, but the manufacturing cost increases
Solution Approach 1:
The supporting rods and elastic parts are integrated into the connector body as a single component structure. This merging eliminates the need for separate fastening elements and additional assembly steps, reducing manufacturing complexity and cost while maintaining reliable attachment.
Solution Approach 2:
The elastic parts automatically secure the connector to the circuit board through their deformation capability, providing inherent fixation without requiring additional fasteners or complex assembly processes. This self-securing mechanism reduces both manufacturing cost and assembly complexity.
