Plug Connector Fixing Bracket Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector design is prone to breakage due to the thin and small annular wall of the plug insulator, which increases the risk of collapse when trying to reduce the size of the connector for substrate coupling.
Innovation Solution
A plug connector with a reinforced fixing bracket design, featuring a plug insulator with a rod-like structure made of synthetic resin and a plug connector fixing bracket that includes a receiving surface, transverse and longitudinal outer walls, and a transverse inner wall, which disperses force and prevents deformation or collapse.

Engineering Contradiction Analysis
1Volume of moving object
If the size of the plug connector is reduced by making the annular wall thin and small, then the connector size is reduced, but the risk of breakage and collapse of the plug connector fixing bracket and annular wall increases
Solution Approach 1:
The fixing bracket extends in the thickness direction (third dimension) of the plug insulator with protruding portions that engage with recesses in the circuit board. This dimensional extension provides additional structural support and mounting stability without increasing the planar footprint of the connector, thus reducing size while maintaining strength.
Solution Approach 2:
The fixing bracket is formed by integrating multiple functional portions (mounting portion, protruding portions, reinforcing structures) into a single composite structure that combines rigid support elements with engagement features. This composite design distributes mechanical loads effectively and prevents collapse without requiring thicker annular walls.
2Volume of moving object
If the annular wall is made thin to reduce connector size, then the connector becomes more compact, but the reliability of the plug connector structure decreases due to high breakage risk
Solution Approach 1:
The fixing bracket utilizes the thickness direction of the plug insulator to create protruding portions that extend beyond the main body. These protrusions engage with corresponding recesses in the circuit board, providing reliable mechanical attachment and structural reinforcement without requiring increased planar dimensions, thus maintaining compactness while improving reliability.
Solution Approach 2:
The fixing bracket is divided into functionally distinct portions: a mounting portion that attaches to the plug insulator and protruding portions that engage with the circuit board. This segmentation allows each portion to be optimized for its specific function, with the protruding portions providing reliable engagement while the mounting portion maintains a thin profile for compactness.

AI summary
Provided is a plug connector having an insulator and a plug connector fixing bracket that is hard to collapse (break). A plug connector (15) is attachable to and detachable from a receptacle connector (35) and includes: a plug insulator having an outer wall that includes a pair of longitudinal walls and a pair of transverse walls together constituting an annular projection engageable with an engagement recess of the receptacle connector (35); a plug contact group arranged in a row and supported by the longitudinal wall of the outer peripheral wall, contacts a receptacle contact group when the annular projection is fit into the engagement recess, and is connected to a circuit pattern of a plug side circuit board; and a plug connector fixing bracket mounted on the transverse walls. The plug connector fixing bracket includes a receiving surface facing a bottom surface of the transverse walls, a transverse outer wall and a transverse inner wall that bend from the receiving surface and respectively extend along an inner surface and an outer surface of the transverse walls, and a pair of longitudinal outer walls that bends from the receiving surface and extends along outer surfaces of the longitudinal walls.
