Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the terminals are exposed in air with elastic arms extending forward, then the connector structure is simple and easy to manufacture, but the electric field is easily dissipated resulting in poor capacitive resistance characteristics and high frequency loss
Solution Approach 1:
The patent applies nesting by placing the signal terminal inside a cavity formed by the insulating body, which is further nested within the housing structure. This nested configuration contains the electric field within the cavity, preventing field dissipation into air and improving capacitive resistance characteristics while maintaining manufacturing simplicity
Solution Approach 2:
The patent introduces dielectric material as an intermediary substance filling the cavity surrounding the signal terminal. This intermediary material mediates between the exposed terminal structure and the external environment, providing electrical insulation and containing the electric field to reduce high frequency signal loss
2Device complexity
If the terminals are exposed in air, then the connector structure is simple, but the signal transmission speed is slow and crosstalk interference occurs
Solution Approach 1:
The signal terminal is nested within a cavity formed by the insulating body, which is itself nested within the housing. This nested arrangement provides electromagnetic shielding that reduces crosstalk interference between adjacent terminals, enabling faster and more reliable signal transmission without significantly increasing structural complexity
Solution Approach 2:
The patent applies local quality by providing different structural characteristics to different parts of the connector. The cavity structure and dielectric material are specifically positioned around the signal terminal to optimize local electromagnetic properties, improving signal transmission speed and reducing crosstalk in critical areas while maintaining overall structural simplicity
3Ease of manufacture
If the terminals are exposed in air, then the manufacturing process is simple, but the capacitive resistance characteristics are poor affecting signal quality
Solution Approach 1:
The signal terminal is nested within a cavity formed by the insulating body, which is further nested within the housing structure. This nested configuration naturally contains the electric field and improves capacitive resistance characteristics without requiring complex manufacturing processes, as the cavity is formed during the injection molding of the insulating body
Solution Approach 2:
The patent changes the physical parameters of the terminal environment by introducing a cavity structure and dielectric material, which alter the electrical characteristics (capacitive resistance) of the terminal. This parameter change improves signal quality and transmission reliability while maintaining manufacturing simplicity through integrated mold design

This design reduces high-frequency signal loss and improves crosstalk, providing a stable environment for high-frequency signal transmission by increasing capacitive resistance and matching impedance requirements.
Implementation Method 1
The first main body and the second main body altogether limit the channel used to receive the signal terminals, thereby enhancing the dielectric coefficient of the surrounding environment of the signal terminal, adjusting the impedance of the signal terminal
Implementation Method 2
the electric field to be be easily dissipated when the electrical connector is used to transmit high frequency signals, thus having ill capacitive resistance characteristics

AI summary
An electrical connector includes: a first main body, having a first wall surface and a second wall surface; a second main body, mounted on the first main body, and having a third wall surface and a fourth wall surface. A first channel is formed between the first wall surface and the third wall surface. A second channel is formed between the second wall surface and the fourth wall surface and is communicated with the first channel. A signal terminal has a fixing portion accommodated in the first channel and fixed by at least one of the first main body and the second main body, and an elastic arm formed by extending from the fixing portion and accommodated in the second channel. A contact portion is provided on the elastic arm and is exposed to the first main body in a left-right direction to be in contact with the mating member.
