Solution Overview
Problem
Existing connector devices face issues with easy disconnection due to imprecise alignment, low mating strength, and high noise interference, while occupying excessive space on circuit boards, which limits their efficiency and durability.
Innovation Solution
A connector assembly design featuring a receptacle connector with a shield and insulation body, and a plug connector with a paddle board and insulation body, incorporating adapting structures and elements for improved alignment and electromagnetic shielding, reducing space utilization and enhancing mating strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the metal shield and insulation body are disposed separately on the circuit board, then the connector can provide electromagnetic shielding, but the space utilization on the circuit board increases and mating strength decreases
Solution Approach 1:
The patent combines the metal shield and insulation body into an integrated structure where the metal shield is formed as a unified component with the insulation body, rather than disposing them separately. This merging reduces the total space occupied on the circuit board while maintaining electromagnetic shielding effectiveness through the integrated design.
Solution Approach 2:
The metal shield is nested within or around the insulation body structure, with the shield forming a cage-like structure that encloses the insulation body. This nesting arrangement allows the shield to provide electromagnetic shielding while occupying minimal additional space, as the shield utilizes the same vertical space as the insulation body.
2Ease of manufacture
If the metal shield and insulation body are disposed separately, then manufacturing is simpler, but mating strength and alignment precision deteriorate
Solution Approach 1:
The metal shield and insulation body are merged into a single integrated component that is molded as one piece. This eliminates the need for separate assembly of the shield and insulation body, maintaining manufacturing simplicity while ensuring precise alignment between the shield and insulation body structures, thereby improving mating strength.
3Ease of manufacture
If the insulation body has no shielding structures, then manufacturing is easier, but noise interference increases during high band signal transmission
Solution Approach 1:
The shielding structures are merged into the insulation body as an integrated feature rather than separate components. The metal shield is formed as part of the insulation body assembly, providing electromagnetic shielding during high band signal transmission while requiring only a single molding process, thus maintaining ease of manufacture.
4Object-affected harmful factors
If the connector occupies larger space on the circuit board, then more shielding structures can be included, but the space for other devices is limited
Solution Approach 1:
The metal shield is nested within the vertical space of the insulation body, forming a cage structure that encloses the insulation body. This nesting allows the shield to provide comprehensive electromagnetic shielding while occupying the same horizontal footprint as the insulation body, thereby minimizing the space required on the circuit board and leaving more room for other devices.

AI summary
A connector assembly includes a receptacle connector and a plug connector. The receptacle connector includes a shield having a receiving slot and a first insulation body disposed in the receiving slot. The first insulation body includes at least one mating cavity and at least one terminal group disposed in the mating cavity. The first insulation body and the shield collectively define at least one adapting structure. The at least one terminal group has a plurality of elastic terminals arranged as at least one row along a first direction. The plug connector includes a paddle board electrically connected to a cable and a second insulation body secured with the paddle board and the cable. At least one adapting element extends from the second insulation body and is adjacently disposed to the paddle board. The adapting element and the adapting structure are mated to each other.
