Compact Electrical Connector Design for Stable Circuit Board Mounting
Here’s PatSnap Eureka !
Summary
Problems
Existing electrical connectors in expansion interface cards for host devices suffer from positional shifts during assembly and long-term use due to inadequate fixing support, and solutions like extending the bracket to prevent shifts result in excessively large dimensions incompatible with regular enclosures.
Innovation solutions
A structural design featuring a mounting frame with position constraining plates and a connector with retention sections of elastic stiffness, allowing for engagement and secure positioning without altering the original size, providing stability in both longitudinal and lateral directions.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the bracket is extended to form a wing that holds the connector, then the connector stability is improved, but the overall width becomes excessively large and incompatible with regular enclosures
Why choose this principle:
The patent transitions from a two-dimensional planar bracket structure to a three-dimensional structure by adding retention sections with bearing surfaces that extend vertically from the mounting frame. This vertical dimension allows the connector to be held securely without increasing the horizontal width, resolving the contradiction between stability and compact dimensions.
Principle concept:
If the bracket is extended to form a wing that holds the connector, then the connector stability is improved, but the overall width becomes excessively large and incompatible with regular enclosures
Why choose this principle:
The retention sections are integrated into the mounting frame structure, with the bearing sections nested within the space defined by the position constraining plates. This nesting approach allows the connector-holding function to be embedded within the existing frame geometry without adding external width.

Abstract
An electrical connector includes a mounting frame and a connector mounted on a circuit substrate. The mounting frame includes at least one position constraining plate, which includes at least one fixing section. The fixing section includes two spaced bending portions and an engagement section therebetween. The engagement section is engageable with a retention section of the connector. The retention section includes a bearing section engaging and bearing the engagement section and a limiting section formed on at least one side of the bearing section to limit the position of the mounting frame in a lateral direction. To assemble, the retention section of the connector is first set in alignment with the engagement section of the mounting frame and a force is applied to have them engage with each other. The bearing section provides position constraining in a longitudinal direction, while the limiting section provides position limiting in a lateral direction.
