Rotatable Mating Connector Assembly for Low-Height Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connector assemblies face challenges with increased installation requirements, leading to higher mating heights and potential cable damage due to the need for 180-degree rotation, which results in reversed cable folding.
Innovation Solution
A mating connector design with a rotating mechanism that maintains the same cable orientation when transitioning between two circuit boards, utilizing elastic mating arms and locking protrusions to secure the connector without folding the cables, thus reducing the overall height and enhancing mating reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mating connector is rotated by 180 degrees to meet installation requirements, then the connector can be installed on different circuit boards, but the cable outlet direction becomes opposite and requires reverse folding
Solution Approach 1:
The mating connector incorporates a rotatable structure that allows dynamic adjustment of its installation angle. The connector can be rotated to different positions (e.g., 0 degrees, 90 degrees, 180 degrees) to adapt to various installation requirements on circuit boards, while the cable outlet direction remains consistent throughout the rotation, eliminating the need for cable folding or rearrangement.
2Adaptability or versatility
If the cables are reverse folded to accommodate 180-degree rotation, then the outlet directions of cables from two connectors can be arranged together, but the overall height of the electrical connector assembly increases
Solution Approach 1:
The rotatable mating connector maintains a consistent cable outlet direction regardless of its installation orientation. This dynamic adaptability allows two connectors to be installed at different positions without requiring cable folding, thereby maintaining a low and compact mating height for the electrical connector assembly.
3Adaptability or versatility
If the cables are reverse folded to accommodate rotation, then installation requirements can be met, but the cables are prone to damage
Solution Approach 1:
The rotatable mating connector allows the connector body to rotate while the cables remain in their original orientation without folding or bending. This eliminates stress concentrations and potential damage points on the cables, thereby improving cable reliability and reducing the risk of cable failure during installation and operation.

AI summary
A mating connector includes a mating insulating body and a number of mating terminals. The mating connector is configured to be installed on a first circuit board in a first position for mating with a first electrical connector. The first electrical connector includes a first cable. The mating connector is also configured to be installed on a second circuit board in a second position for mating with a second electrical connector. The second electrical connector includes a second cable. The mating connector in the second position is formed by rotating the mating connector in the first position by 180 degrees in a plane where the first circuit board is located. Neither the first cable nor the second cable is folded, and outlet directions of the first cable and the second cable are the same. An electrical connector assembly including the mating connector is also disclosed.
