USB Type-C high-speed connector with terminal local air exposure path

Abstract

This invention discloses a USB Type-C high-speed connector with a partial air exposure path at the terminals, comprising an insulating body and at least one pair of high-speed differential terminals disposed within the insulating body. The high-speed differential terminals sequentially include a contact mating section, a path compensation section, and a solder joint section along the signal transmission direction. The path compensation section is configured as a compensated transmission path that extends relative to a straight path. The insulating body has an air-proof structure in at least a portion of the area corresponding to the path compensation section, so that at least a portion of the outer periphery of the path compensation section directly faces the air medium to form an air medium transmission area, thereby reducing the effective dielectric constant around the path compensation section, reducing high-frequency dielectric loss, and improving insertion loss performance and signal integrity. This invention addresses both the terminal path compensation requirements and low-loss transmission requirements, and is suitable for USB Type-C high-speed connectors.

Claims

1. A USB Type-C high-speed connector with a terminal local air exposure path, comprising: An insulating body and at least one pair of high-speed differential terminals disposed within the insulating body, wherein the high-speed differential terminals sequentially include a contact mating section, a path compensation section, and a solder connection section along the signal transmission direction, wherein the path compensation section is configured as a compensation transmission path that extends relative to a straight path, and the insulating body has an air-avoiding structure in at least a portion of the area corresponding to the path compensation section, so that at least a portion of the outer periphery of the path compensation section directly faces the air medium to form an air medium transmission area, thereby reducing the effective dielectric constant around the path compensation section.

2. The USB Type-C high-speed connector with a terminal partial air exposure path as described in claim 1, wherein the air-exposure structure is one or more of a window slot, clearance slot, through hole or notch structure provided on the insulating body.

3. The USB Type-C high-speed connector with a terminal partial air exposure path as claimed in claim 1, wherein the path compensation segment is disposed on the longer portion of the high-speed differential terminal, and the air medium transmission area is located outside the longer portion.

4. The USB Type-C high-speed connector with a terminal partial air exposure path as described in claim 1, wherein the path compensation segment is a multi-segment bending path structure, the multi-segment bending path structure being any one of a zig-zag shape or a stepped shape.

5. The USB Type-C high-speed connector with a terminal partial air exposure path as claimed in claim 1, wherein the path compensation segment includes at least two bent sub-segments connected sequentially in different directions to increase the effective transmission length of the high-speed differential terminals within a limited installation space.

6. The USB Type-C high-speed connector with a terminal local air exposure path as claimed in claim 1, wherein the air medium transmission area is configured as a continuous or spaced distribution structure along the extension direction of the path compensation segment.
