Description

Technical Field

[0001] This utility model relates to the field of satellite signal receiver technology, and in particular to a housing for a satellite downconverter. Background Technology

[0002] For LNBs (Low-Noise Block downconverters) in satellite signal receivers, the circuit board is typically housed within a casing, with a waveguide mounted on the casing and waveguide probes inside. Because the circuit board is often large in width or length, the casing itself needs to be quite long or wide. This significant expansion in one direction increases the difficulty of installing the LNB, making it challenging to improve its stability. This, in turn, limits the ability of manufacturers to improve product quality.

[0003] Therefore, Chinese patent CN 210670037 U discloses a housing for a satellite downconverter, which includes a rectangular base plate, a first rectangular frame integrally formed on the bottom surface of the rectangular base plate, a second rectangular frame integrally formed on the bottom surface of the rectangular base plate, two rows of cylinders, and a waveguide integrally formed on the bottom surface of the rectangular base plate; a hollow column connected to the waveguide is provided on the top surface of the rectangular base plate, and multiple through holes are provided on the rectangular base plate, with one end of the through hole located in the space enclosed by the first rectangular frame and the other end located in the space enclosed by the second rectangular frame. The LNB housing for the satellite signal receiver provided by this utility model is made into two parts separated by a rectangular base plate, so that circuit boards can be set in the rectangular frames on both the top and bottom surfaces of the rectangular base plate, thereby reducing the length and / or width of the housing, reducing the difficulty of installation, improving the stability of installation, and solving the conventional technical problems mentioned above.

[0004] However, the improved housing has brought about new technical problems. For example, circuit boards need to be installed on both sides of the rectangular base plate. Therefore, not only do two circuit boards need to be assembled, but each circuit board also needs to be equipped with corresponding screw holes, fixing plates and shielding covers. This results in higher overall production costs and more complicated assembly steps. Therefore, a housing for satellite frequency downconverters is proposed. Utility Model Content

[0005] Based on this, it is necessary to provide a housing for a satellite downconverter to address the above-mentioned technical problems. This housing can not only divide the F-connectors into two groups for arrangement, reducing the size of the circuit board in the width or length direction, but also guide one group of F-connectors onto the circuit board and connect them through the guide slot via PIN pins. In this way, multiple groups of F-connectors can be connected using only a single circuit board.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A housing for a satellite downconverter, comprising:

[0008] The housing has a small plate and a large plate on each side;

[0009] A circuit board is disposed on one side of the large board surface;

[0010] The F-connector has two sets, with the two sets of F-connectors respectively distributed on one side of the small plate and the large plate;

[0011] A guide groove, which is provided on the surface of the housing, is used to spatially connect the small plate surface and the large plate surface;

[0012] The F connector located on one side of the large board is directly connected to the circuit board, while the F connector located on one side of the small board is connected to the circuit board through the PIN pin in the guide slot.

[0013] Furthermore, the shell has an upper cavity formed around the small plate surface and a lower cavity formed around the large plate surface.

[0014] Furthermore, two sets of cylinders are distributed at the outer end of the housing corresponding to the position of the F connector;

[0015] One set of cylinders is connected to the upper cavity, and the other set of cylinders is connected to the lower cavity.

[0016] Furthermore, the upper cavity and the lower cavity are respectively used for the assembly of the corresponding F connectors inside them.

[0017] Furthermore, the guide groove has an inlet end and an outlet end on one side corresponding to the small plate surface and the large plate surface, respectively;

[0018] The PIN pin is connected to the F connector at the input end, and the PIN pin is connected to the circuit board at the output end.

[0019] Furthermore, adhesive is applied inside the inlet end to seal the connection between the PIN pin and the inlet end.

[0020] Furthermore, the circuit board is fixed to the large plate surface within the lower cavity by bolts.

[0021] Furthermore, a shielding cover is fixed to the surface of the circuit board by bolts.

[0022] Furthermore, an outer cover is fixed to the edge of the lower cavity to seal the lower cavity.

[0023] Furthermore, a waveguide is provided on the side of the housing away from the F connector.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The housing for satellite frequency downconverter provided by this utility model can not only divide the F connectors into two groups for arrangement, reducing the size of the circuit board in the width or length direction, but also guide one group of F connectors to the circuit board and connect them through the PIN pins via the guide groove, while the other group of F connectors can be directly connected to the circuit board. In this way, multiple groups of F connectors can be connected with only a single circuit board.

[0026] At the same time, using only a single circuit board, compared to the conventional setup of two circuit boards, eliminates the need for corresponding shielding covers, fixing boards, and screw structures, and also eliminates the need for assembly of these structures. This results in a reduction in overall cost and a simplified assembly process, making it more practical.

[0027] By applying adhesive within the guide groove, the shielding cover and outer cover on the small board surface can be omitted, while the connection between the PIN pins and the F connector can be sealed with adhesive, thus promoting a stable connection. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0041] As described in the background art, the aforementioned housing presents new technical problems. For example, circuit boards need to be installed on both sides of the rectangular base plate. Therefore, not only are two circuit boards required for corresponding assembly, but each circuit board also needs to be equipped with corresponding screw holes, fixing plates, and shielding covers. This results in higher overall production costs and more complicated assembly steps.

[0042] To solve this technical problem, this utility model provides a housing for a satellite downconverter, which is applied to a satellite signal receiver.

[0043] For details, please refer to Figures 1-7 As shown, the housing for the satellite downconverter specifically includes:

[0044] The housing 1 has a small plate 11 and a large plate 12 on its two sides respectively;

[0045] Circuit board 2 is disposed on one side of the large board surface 12;

[0046] F-connectors 3, which are in two sets, are respectively distributed on one side of the small plate surface 11 and the large plate surface 12;

[0047] A guide groove 4 is provided on the surface of the housing 1 to spatially connect the small plate surface 11 and the large plate surface 12.

[0048] The F connector 3 located on one side of the large board surface 12 is directly connected to the circuit board 2, and the F connector 3 located on one side of the small board surface 11 is connected to the circuit board 2 through the PIN pin 31 in the guide groove 4.

[0049] The housing for satellite frequency downconverter provided by this utility model can, while satisfying the requirement of arranging the F connectors 3 into two groups and reducing the size of the circuit board 2 in the width or length direction, also guide one group of F connectors 3 to the circuit board 2 and connect them through the guide groove 4 via the PIN pin 31, and the other group of F connectors 3 can be directly connected to the circuit board 2. In this way, multiple groups of F connectors 3 can be connected with only a single circuit board 2.

[0050] Meanwhile, using only a single circuit board 2, compared to the conventional setup of two circuit boards, eliminates the need for corresponding shielding covers, fixing boards, and screw structures, and also eliminates the need for assembly of these structures. This results in a reduction in overall cost and a simplified assembly process, making it more practical.

[0051] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0052] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0054] Example 1

[0055] Please refer to Figures 1-7 As shown, a housing for a satellite downconverter includes:

[0056] The housing 1 has a small plate 11 and a large plate 12 on each side, as shown below. Figure 1 As shown, the small plate 11 is located at the top of the housing 1, and the large plate 12 is located at the bottom of the housing 1;

[0057] Circuit board 2 is disposed on one side of the large board surface 12;

[0058] F-connectors 3, which are in two groups, are distributed on one side of the small plate surface 11 and the large plate surface 12 respectively, and the F-connectors 3 in each group are located on the same horizontal line.

[0059] By setting multiple F-connectors 3 in two groups and stacking the two groups of F-connectors 3 one on top of the other, the single-sided dimension of the required length or width of the circuit board 2 can be effectively reduced when connecting it to the circuit board 2.

[0060] A guide groove 4 is provided on the surface of the housing 1 to spatially connect the small plate surface 11 and the large plate surface 12.

[0061] The F connector 3 located on one side of the large board surface 12 is directly connected to the circuit board 2, and the F connector 3 located on one side of the small board surface 11 is connected to the circuit board 2 through the PIN pin 31 in the guide groove 4.

[0062] This embodiment incorporates a two-set design for the F-connector 3, which reduces the length or width dimensions of the conventional circuit board while allowing the simultaneous connection of the two sets of F-connectors 3 using only a single circuit board 2 and PIN pins 31. Furthermore, by reducing the number of circuit boards compared to conventional housings, the required screws, shielding covers, and fixing boards can be reduced accordingly. This lowers the overall production cost and simplifies the assembly process, making assembly easier.

[0063] Example 2

[0064] The housing for the satellite downconverter provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4 As shown, the shell 1 has an upper cavity 13 formed around the small plate 11, and the shell 1 has a lower cavity 14 formed around the large plate 12.

[0065] like Figure 5 As shown, two sets of cylinders 15 are distributed at the outer end of the housing 1 corresponding to the position of the F connector 3;

[0066] One set of the cylinders 15 is connected to the upper cavity 13, and the other set of cylinders 15 is connected to the lower cavity 14;

[0067] The upper cavity 13 and the lower cavity 14 are respectively used for the assembly of the corresponding F connector 3 inside them;

[0068] The circuit board 2 is fixed to the large plate surface 12 within the lower cavity 14 by bolts.

[0069] In this embodiment, there are eight F-connectors 3, which are divided into two groups of four, as follows: Figure 5The F-connectors 3 located at the bottom can be directly connected to the circuit board 2 through the input end, while the input end of the F-connectors 3 located at the top can be connected to the top of the PIN pin 3. The PIN pin 3 can be connected to the circuit board 2 through the bottom end. In this way, eight F-connectors 3 can be synchronously connected to the circuit board 2 through only four PIN pins 3.

[0070] In this embodiment, the thickness between the small plate 11 and the large plate 12 is 2.5 mm, which can reduce material consumption.

[0071] Example 3

[0072] The housing for the satellite downconverter provided in Embodiment 1 or 2 is further optimized, such as... Figure 6 As shown, the guide groove 4 has an inlet end 41 and an outlet end 42 on one side corresponding to the small plate surface 11 and the large plate surface 12, respectively;

[0073] The PIN pin 31 is connected to the F connector 3 at the input end 41, and the PIN pin 31 is connected to the circuit board 2 at the output end 42.

[0074] Adhesive 43 is applied inside the inlet end 41 to seal the connection between the PIN pin 31 and the inlet end 41;

[0075] The input end of the F connector 3 located on one side of the small board 11 can be connected to the top of the PIN pin 31. Conventionally, the connection point of the PIN pin needs to be sealed and shielded with a sealing cap. However, in this embodiment, since the PIN pin 31 is used for conduction, after connection, glue can be directly applied to the input end 41. This can seal the connection point between the PIN pin 31 and the input end of the F connector 3, which is simple and convenient. At the same time, the glue after fixing can also enhance the connection effect, ensure the stability of the connection, achieve waterproofing, and enhance the standing wave function.

[0076] Example 4

[0077] The housing for the satellite downconverter provided in Embodiment 3 has been further optimized, such as... Figure 5 The surface of the circuit board 2 shown is fixed with a shielding cover 16 by bolts. The shielding cover 16 can cover and protect the corresponding component area on the surface of the circuit board 2, thereby ensuring the stability of the application of the circuit board 2 itself.

[0078] An outer cover 17 is fixed to the edge of the lower cavity 14 to seal the inside of the lower cavity 14. The outer cover 17 can seal the inside of the lower cavity 14 relatively tightly, which can prevent dust particles and other particles from falling into the lower cavity 14, thereby ensuring the stable use of the internal circuit board 2. The upper cavity 13 can be sealed with glue alone. Since there is no need to set up a circuit board, the relevant structure can be omitted.

[0079] The housing 1 is also provided with a waveguide 18 on the side away from the F connector 3.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0081] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments.
