Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency adapter boards, in particular to a micro-assembled high-frequency adapter board. Background Art

[0002] The welding of RF connectors is one of the key factors affecting the performance of RF boards. RF signals need to be transmitted externally through RF connectors. The general design is to weld the RF connectors to the interface pads on the edge of the RF board, so that the RF board can communicate with the outside through connectors (such as SMA, 2_4-K, etc.).

[0003] Traditional RF connectors are directly connected to RF boards through welding. Since the RF connectors are removed during debugging and installation of the RF boards, the pads where the connectors are welded to the boards will be stressed. In addition, some RF connector interfaces are externally connected to heavy isolators, which can easily cause the pads at the RF connector interfaces to fall off. The only way to do this is to solder with tin, which is time-consuming and labor-intensive and can easily cause other changes in functions, affecting the reliability of product design.

[0006] Preferably, the RF copper sheet shrinks toward one end of the RF connector.

[0008] Preferably, a welding pin is provided at one end of the RF connector, and the welding pin is welded to the RF copper sheet.

[0009] Preferably, one end of the RF board is soldered to the ground copper sheet and one end of the RF copper sheet by tinning.

[0014] (1) The utility model is welded to the RF connector and the RF board at both ends of the adapter board body, and the adapter board body includes a substrate, a ground copper sheet, a ground network through-hole, a RF copper sheet and a recessed portion.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figures 1 to 4 As shown, a micro-assembled high-frequency adapter board includes a radio frequency connector 1, a radio frequency board 2, an adapter board body 3, a substrate 4, a ground copper sheet 5, a ground network through hole 6, a radio frequency copper sheet 7, a recessed portion 8 and a welding pin 9.

[0021] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the two ends of the adapter board body 3 are respectively welded to the RF connector 1 and the RF board 2. Specifically, the adapter board body 3 includes a substrate 4, a ground copper sheet 5, a ground network through hole 6, a RF copper sheet 7 and a recessed portion 8. A soldering pin 9 is provided on one end of the RF connector 1, and the soldering pin 9 is welded to the RF copper sheet 7; one end of the RF board 2 is soldered to the ground copper sheet 5 and one end of the RF copper sheet 7 by dragging tin. Through the split-board design, the interface of the RF board 2 is separated from the interface of the RF connector 1, and the adapter board body 3 is added. When debugging and installing, to remove the RF board 2, it is only necessary to remove the solder at the welding point between the adapter board body 3 and the RF board 2, without removing the RF connector 1, which reduces the time and cost of modification and production, is conducive to the stability of the technical status, improves efficiency, and improves the reliability of product design.

[0024] During use, when the RF board 2 to be installed is inconsistent, the adapter board body 3 does not need to be changed, and can adapt to RF boards of different specifications 2. If the adapter board needs to modify the circuit or replace the RF connector 1, since the adapter board body 3 does not contain components, the modification workload is small and does not affect the functional realization of the RF board 2. The adapter board body 1 can be prepared in advance as an unchanged part, reducing production and control costs and reducing production cycles.

[0025] The outer periphery of the substrate 4 is covered with a ground copper sheet 5 , and a plurality of ground network through holes 6 are provided on opposite sides of the ground copper sheet 5 , which facilitates soldering and effectively strengthens the ground signal connection.

[0026] A radio frequency copper sheet 7 is fixedly provided in the middle of the substrate 4 , and the radio frequency copper sheet 7 shrinks toward one end of the radio frequency connector 1 , so as to optimize the impedance change at the welding point and make the impedance change smoother.

[0027] Recesses 8 are formed between the two sides of the RF copper sheet 7 and the ground copper sheet 5 , respectively. The recesses 8 are filled with green oil to prevent solder from overflowing when installing and removing the adapter board body 3 and the RF board 2 , causing a short circuit between the ground copper sheet 5 and the RF copper sheet 7 .

[0028] The maximum width of the RF copper sheet 7 is smaller than the width of the recessed portion 8 .

[0029] The substrate 4 is Rogers 5880. The length L1 of the adapter board body 3 is less than or equal to 4 mm, and the width L2 is less than or equal to 5.9 mm, so as to better match the connection between the RF connector 1 and the RF board 2 .

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
