Existing connectors used in MIMO technology for mobile communication repeaters face challenges in maintaining high-frequency signal transmission performance while being compactly formed to occupy minimal space.
Innovation Solution
A connector design featuring a connection pin partially inserted into a board, a dielectric body with a first opening for the connection pin, and a ground body with a second opening for the dielectric body, where the connection pin has a central portion and first and second connection portions with varying diameters, and the dielectric body includes dielectric holes or grooves for thermal expansion.

Engineering Contradiction Analysis
1Volume of moving object
If the connector is made compact to occupy small space, then the volume and dimensions are reduced, but the high-frequency signal transmission performance deteriorates
Solution Approach 1:
The connector is divided into distinct functional segments: a connection pin with varying diameter sections, a dielectric body with integrated grounding structures, and a ground body. This segmentation allows each component to be optimized independently - the connection pin can maintain appropriate dimensions for signal integrity while the overall connector remains compact through efficient spatial arrangement of segments.
Solution Approach 2:
The design implements nested structures where the connection pin is inserted into the dielectric body, which in turn is inserted into the ground body. The dielectric body contains grounding protrusions that extend into the ground body, creating multiple levels of nesting. This nesting approach maximizes functional density within a compact volume, maintaining signal transmission performance while minimizing overall connector dimensions.
2Reliability
If the connection pin diameter is increased to improve coupling, then the signal transmission performance is improved, but the connector volume increases
Solution Approach 1:
The connection pin features non-uniform diameter along its length, with larger diameter sections at the connection portions and smaller diameter in the central portion. This local quality variation allows the pin to provide strong coupling and mechanical support where needed while maintaining compact overall dimensions. The varying diameter profile optimizes both coupling performance and space efficiency without requiring a uniformly large pin throughout.
