[0002] In the RF industry, signal matrix switching is primarily accomplished through an RF switching matrix. Its core function is to dynamically allocate signal paths between multiple RF signal sources and target devices, improving system flexibility, automation, and signal transmission efficiency. The essence of RF matrix switching is to achieve multiple-input, multiple-output (M×N) signal routing through a matrix topology.

[0003] In order to realize multi-input and multi-output routing, several RF modules are connected vertically and horizontally. In order to ensure fast connection between RF modules, a blind-plug structure is configured for the RF modules. For example, the application with publication number CN118174059A discloses a two-dimensional bidirectional RF blind-plug chassis structure, which includes: a box body, forming a cavity for installing RF components, an adapter plate is provided in the cavity, and both sides of the adapter plate are used to connect RF components; at least two groups of RF components, including a first RF component and a second RF component respectively connected to the two sides of the adapter plate; an alignment structure is provided between the first RF component and the second RF component and the adapter plate, and the first RF component and the second RF component are connected to each other by an adapter connector passing through the adapter plate. The alignment structure realizes precise guidance and positioning of the first RF component and the second RF component, realizes blind-plug connection of the RF channel, simplifies the layout and connection structure of the RF components, and realizes more accurate and fast connection. It can not only form a stable and reliable connection structure between multiple RF components, but also control the overall structure and size.
