AI Technical Summary

Technical Problem

The existing coaxial connector designs suffer from unstable communication performance due to shifts in the connection position, leading to the presence of a large air layer between the housing movable part and the insulator, deviating from the designed communication performance values.

Method used

A coaxial connector connection structure is designed where the first and second coaxial connectors are connected with overlapping portions defined, and the dielectrics are positioned to avoid these overlapping areas, ensuring an air layer is maintained, thereby stabilizing communication performance even with positional shifts.

Benefits of technology

This design ensures stable communication performance by maintaining a consistent coaxial state and minimizing the impact of positional deviations between connectors, even when an air layer is present.

Abstract

To make it possible to obtain stable communication performance even if the connection position of a second coaxial connector relative to a first coaxial connector is misaligned.SOLUTION: A coaxial connector connection structure 28 is a connection structure between a first coaxial connector 40 and a second coaxial connector 70. The first coaxial connector includes a first inner conductor 50, a first outer conductor 60, and a first dielectric 42, and the second coaxial connector includes a second inner conductor 80, a second outer conductor 90, and a second dielectric 72. When, in a connected state of both the coaxial connectors, a portion where the first inner conductor and the second inner conductor overlap in a connection direction is defined as an inner-side overlap portion E1, and a portion where the first outer conductor and the second outer conductor overlap in the connection direction is defined as an outer-side overlap portion E2, both the first dielectric 42 and the second dielectric 72 are positioned to avoid both the inner-side overlap portion and the outer-side overlap portion.SELECTED DRAWING: Figure 5
