[0026] In order to make the technical personnel in the art better understand the technical scheme of the present application, the following will be further described in detail with reference to the drawings.

[0027] The utility model provides a kind of high-efficiency heat-dissipation radio frequency connector as Figs. 1-3 As shown in the figure, including the plug 2 and socket 3 of radio frequency connector 1, inner conductor 21 is arranged in plug 2, and matching jack 31 is arranged in socket 3;

[0028] Specifically, a plurality of uniformly spaced heat dissipation grooves 22 are formed on the inner wall of the plug 2, and a plurality of heat dissipation fins 23 are fixed in the heat dissipation grooves 22, a threaded hole 24 is formed on the outer wall of the plug 2, and a threaded groove is formed on the heat dissipation fin 23, which is matched with the threaded hole 24.

[0029] Specifically, a plurality of uniformly spaced installation grooves 32 are formed on the inner wall of the socket 3, and a plurality of heat dissipation blocks 33 are fixed in the installation grooves 32, a threaded hole 34 is formed on the inner wall of the socket 3, and a threaded groove is formed on the inner side of the heat dissipation block 33, which is matched with the threaded hole 34.

[0030] Specifically, the heat dissipation block 33 is T-shaped, and the heat dissipation plate 35 extends to both sides on the outer side of the heat dissipation block 33, and the heat dissipation plate 35 on the outer side of the heat dissipation block 33 is enclosed on the outer wall of the socket 3.

[0031] Specifically, the adjacent heat dissipation plates 35 are in contact, that is, the plurality of heat dissipation plates 35 enclose a ring shape.

[0032] Specifically, the heat dissipation fins 23 and the inner side of the heat dissipation blocks 33 are smaller in size than the outer side, and the overall length of the heat dissipation fins 23 and the heat dissipation blocks 33 matches.

[0033] Specifically, the threaded hole one 24 is matched and connected with the threaded hole two 34, and the heat dissipation fins 23 and the heat dissipation blocks 33 are both welded and fixed in the corresponding heat dissipation grooves 22 and mounting grooves 32.

[0034] Specifically, the heat dissipation fins 23 and the heat dissipation blocks 33 are both made of copper alloy.

[0035] In this embodiment, the plug 2 is made of appropriate material to ensure good mechanical properties and electrical properties. A plurality of evenly spaced heat dissipation grooves 22 are accurately machined on the inner wall of the plug 2. The size and spacing of the heat dissipation grooves 22 need to be designed according to the specific heat dissipation requirements and overall structure of the radio frequency connector.

[0036] Specifically, the heat dissipation fins 23 are prepared, and the heat dissipation fins 23 are made of copper alloy material and utilize its good heat conductivity. The heat dissipation fins 23 are processed into a shape and size matching the heat dissipation grooves 22, and a threaded groove is machined on the heat dissipation fins 23 to match the threaded hole one 24 on the outer wall of the plug 2.

[0037] Specifically, the heat dissipation fins 23 are fixed in the heat dissipation grooves 22 by welding. The welding temperature and time need to be strictly controlled during the welding process to ensure that the connection between the heat dissipation fins 23 and the heat dissipation grooves 22 is firm, and the heat conductivity and threaded groove of the heat dissipation fins 23 are not damaged.

[0038] In this embodiment, the socket 3 is made, and a plurality of evenly spaced mounting grooves 32 are machined on the inner wall of the socket 3. The mounting grooves 32 require high machining precision to ensure the installation precision and stability of the heat dissipation blocks 33.

[0039] Specifically, the heat dissipation blocks 33 are made, and copper alloy material is also selected. The heat dissipation blocks 33 are processed into a T-shaped shape, and the outer side extends to both sides to form heat dissipation plates 35. A threaded groove is machined on the inner side of the heat dissipation blocks 33 to match the threaded hole two 34 on the inner wall of the socket 3.

[0040] Specifically, the heat dissipation blocks 33 are fixed in the mounting grooves 32 by welding. After welding is completed, the heat dissipation plates 35 on the outer side of the plurality of heat dissipation blocks 33 enclose the outer wall of the socket 3, and the adjacent heat dissipation plates 35 are in close contact, forming a ring structure.

[0041] In this embodiment, after the components of the plug 2 and the socket 3 are prepared, the assembly and connection operations are performed. The inner conductor 21 of the plug 2 is aligned with the socket 3, and then the threads one 24 on the outer wall of the plug 2 are connected to the threads two 34 on the inner wall of the socket 3 by rotating the plug 2 and the socket 3. During the connection process, one end of the heat sink 23 in the plug 2 gradually approaches and finally matches the connection with one end of the heat sink block 33 in the socket 3.

[0042] In this embodiment, the heat dissipation area is increased: the arrangement of the heat sink 23 and the heat sink block 33 greatly increases the heat dissipation area of the radio frequency connector. When the radio frequency connector generates heat during operation, the heat can be conducted through the inner conductor 21 to the plug 2 and the socket 3, and then quickly dissipated to the surrounding environment through the heat sink 23 and the heat sink block 33. For example, when high-power radio frequency signals are transmitted, a large amount of heat will be generated in a short time, and at this time the heat sink 23 and the heat sink block 33 can quickly conduct heat out, avoiding the accumulation of heat inside the connector, thereby ensuring the normal working temperature of the radio frequency connector.

[0043] Specifically, the heat sink 23 and the heat sink block 33 are matched and connected when the plug 2 and the socket 3 are connected, forming a continuous heat dissipation channel. This design optimizes the heat conduction path, reduces thermal resistance, and enables heat to be more efficiently conducted from the inside to the outside. At the same time, the heat dissipation plate 35 on the outside of the heat sink block 33 forms a ring, further enhancing the heat dissipation effect and enabling faster heat dissipation to the surrounding air.

[0044] In this embodiment, the matching connection of the threads one 24 and the threads two 34 makes the connection between the plug 2 and the socket 3 more secure and stable. Even if subjected to external forces during use of the radio frequency connector, it is not easy to loosen or fall off, ensuring the stability and reliability of signal transmission.

[0045] Specifically, the heat sink 23 and the heat sink block 33 are fixed in the heat dissipation groove 22 and the mounting groove 32 respectively by welding, which ensures the secure and reliable connection between the heat dissipation components and the plug 2 and the socket 3. During long-term use, the heat sink 23 and the heat sink block 33 will not loosen or fall off due to factors such as vibration or temperature changes, thereby ensuring the stability of the heat dissipation effect.

[0046] In this embodiment, the heat sink 23 and the heat sink block 33 are made of copper alloy material, which has excellent heat conduction performance and can quickly conduct heat away. This enables the radio frequency connector to maintain a lower temperature under high-power working conditions, prolonging the service life of the connector and improving its working efficiency and reliability.

[0047] Specifically, the copper alloy also has good mechanical properties, and can withstand certain external force and pressure. In the assembly and use of the radio frequency connector, the heat dissipation fin 23 and the heat dissipation block 33 will not be deformed or damaged due to external force, ensuring the overall structural stability of the radio frequency connector.

[0048] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
