Plug Connector Two-Row Terminal Arrangement Width Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RJ45 and RJ11 connectors have a large width due to their straight terminal arrangements, which does not meet the demand for high-density installations in multifunctional electronic appliances.
Innovation Solution
The connectors are redesigned with plug terminals arranged in two rows along the width direction, with each terminal extending in the front-and-back direction, and a cable with core wires electrically connected to these terminals, allowing for a symmetric and space-saving configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If terminals are arranged in a straight row along the left-and-right direction, then the connector structure is simple and easy to manufacture, but the width of the connector becomes large
Solution Approach 1:
The patent applies dimensionality change by transitioning from a one-dimensional straight-row arrangement to a two-dimensional arrangement where terminals are distributed in both the left-and-right direction and the upper-and-lower direction. This allows the same number of terminals to be packed into a smaller width while maintaining manufacturing simplicity through standardized positioning structures.
2Adaptability or versatility
If multiple interfaces are distributed in the left-and-right direction to meet multifunctional needs, then each interface can be accessed, but the overall width required increases
Solution Approach 1:
The patent enables multiple interfaces (RJ45 and RJ11) to coexist by utilizing two-dimensional space distribution. The terminals are arranged in two rows in the width direction, allowing multiple communication interfaces to be integrated within a compact width of 5.8mm, thereby achieving multifunctionality without proportionally increasing the connector width.

AI summary
The present disclosure discloses a plug connector including an insulating housing, a number of plug terminals and a cable. The insulating housing includes a width direction extending along a left-and-right direction. The plug terminals are retained by the insulating housing and arranged in two rows in the width direction of the insulative housing. The plug terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each plug terminal extends along a front-and-back direction. The cable includes a number of core wires correspondingly and electrically connected with the plug terminals. A connector assembly including the plug connector and the mated socket connector is also disclosed in the present disclosure.
