This utility model relates to the field of radio frequency connector technology and discloses a quick-plug radio frequency connector, including a male terminal and a female terminal. The outer wall of the male terminal connection is provided with an external thread, and the inner wall of the female terminal connection is provided with an internal thread. A limit block is provided inside the male terminal, and a male wire core is provided at the center of the limit block. A support block is provided inside the female terminal, and a female wire core is provided at the center of the support block. A plug-in port is provided on the side of the male terminal away from the female terminal, and a gap is provided between the male wire core and the plug-in port. A wiring port is provided on the side of the female terminal away from the male terminal, and a gap is provided between the female wire core and the wiring port. A wiring groove is provided on the side of the male wire core close to the female wire core, and the male wire core and the female wire core are connected through the wiring groove. A connecting component is provided between the male terminal and the female terminal for aligning and connecting the male wire core and the female wire core and for heat dissipation, which solves the problem that existing equipment cannot cool down in time.

This utility model relates to a heat-dissipating receiver housing in the field of receivers. It includes a middle housing with a shelf inside. Compression springs are installed on both the left and right sides of the inner wall of the shelf, and clamping plates are attached to the ends of the compression springs. Thermally conductive silicone blocks are installed around the top surface of the shelf. After a circuit board is placed in the inner cavity of the shelf, the compression springs on the shelf drive the clamping plates closer to the circuit board, causing the clamping plates to engage with the outer side of the circuit board. Compared to traditional screw fixing methods, this mechanism allows for quick tool-free assembly and disassembly. The thermally conductive silicone blocks attract and dissipate the heat generated by the circuit board during operation, thus achieving efficient heat dissipation and preventing heat accumulation that accelerates component aging.
