Connector Antenna Terminal Length Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector designs for wireless communication devices often result in overly strong radio wave transmission when using a terminal as an antenna, violating regulatory limits, and require complex assembly processes with separate antennas.
Innovation Solution
A connector design featuring a housing with L-shaped terminals, where one terminal is used for power and another serves as a shorter antenna, integrated into the same terminal insertion holes, preventing excessive radio wave strength and simplifying assembly by using common manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal is used as an antenna for transmission, then wireless communication functionality is achieved, but the transmitted radio wave strength may become excessively strong and violate regulations
Solution Approach 1:
The patent changes the physical parameter of the antenna terminal by shortening its length. The antenna terminal has a shorter connection portion compared to other terminals, which directly controls the radiation strength to comply with regulations while maintaining wireless communication functionality
2Adaptability or versatility
If a dedicated antenna is separately provided, then antenna functionality is achieved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent merges the antenna function with the existing terminal structure. The antenna terminal is integrated into the connector housing alongside other terminals, eliminating the need for a separate dedicated antenna component and simplifying assembly
Solution Approach 2:
The connector housing and terminal structure serve multiple functions: electrical connection through terminals and wireless communication through the antenna terminal. This multi-functionality reduces the overall component count and assembly complexity
3Power
If external electric wire is connected to terminal to increase transmitted radio wave strength, then transmission strength is improved, but radio wave regulations are violated
Solution Approach 1:
The patent controls the transmitted radio wave strength by changing the physical parameter of the antenna terminal - specifically its length. The shortened connection portion of the antenna terminal inherently limits the radiation strength to comply with regulations, eliminating the need for external wires that would increase strength

AI summary
A connector is to be mounted on a printed circuit board connected to a mating connector. The connector includes a housing to be fixed to the printed circuit board, the housing including a plurality of terminal insertion holes extending parallel to the printed circuit board and a plurality of terminals, each of the plurality of terminals including a connection portion and a leg portion forming an L-shape, the connection portion being inserted into one of the terminal insertion holes toward the mating connector such that the connection portion is supported by the housing and such that the leg portion is electrically connectable to the printed circuit board. The plurality of terminals includes a first terminal to be connected to the mating connector, and a second terminal to serve as an antenna. The connection portion of the second terminal is shorter than the connection portion of the first terminal.
