[0002] The full name of power divider is power distributor. It is a device that divides one input signal energy into two or more outputs with equal or unequal energy. It can also combine the energy of multiple signals into one output, which is also called a combiner.

[0003] The existing power splitter / combiner can only be used as a single device. When it is necessary to perform splitting and combining at the same time during use, multiple devices need to be installed to meet the use requirements.

[0004] In addition, the existing power divider / combiner is installed outdoors and is affected by the ambient temperature, which may cause the internal temperature of the power divider / combiner to change. When the power divider / combiner works in a high temperature environment for a long time, the electronic components may be damaged. Summary of the invention

[0005] The object of the present invention is to provide a microstrip radio frequency power divider / combiner to solve the problems raised in the above background technology.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a power divider / combiner with microstrip radio frequency function, comprising a power divider / combiner body, wherein the power divider / combiner body comprises an upper shell and a lower shell;

[0008] The upper shell and the lower shell are both U-shaped plates, and the upper shell and the lower shell are spliced ​​to form a closed cavity;

[0011] The power divider / combiner body is installed on the wall, and the lower shell is close to one side of the wall. Since the wall is affected by the outside, the temperature changes greatly. Compared with aluminum alloy, plastic is less affected by the outside and the temperature changes less, thereby reducing the heat transfer from the lower shell to the cavity formed by the upper shell and the lower shell;

[0012] A PCB board is installed between the relatively distributed connection ports, the PCB board includes a board body 1 and a board body 2, a power divider circuit and a combiner circuit are respectively arranged on the board body 1 and the board body 2, and a radio frequency circuit is arranged between the power divider circuit and the combiner circuit;

[0018] Furthermore, both ends of the fixing member are provided with a base and an extension block, the extension block is located on the upper side of the base, and the extension block is inserted into the card slot;

[0019] During installation, the extension block is inserted into the slot and fixed to the wall through screws passing through the base.

[0020] Furthermore, a power divider / combiner body is installed outside the power divider / combiner body, and end covers are installed in both end ports formed by the power divider / combiner body and the outer shell;

[0021] The outer shell is installed on the outside of the power divider / combiner body to protect the power divider / combiner body;

[0022] At the same time, a chamber is formed between the power divider / combiner body and the outer shell, and both ends of the chamber are closed by end covers. In hot weather, the sun shines on the outer side of the outer shell, and the heat transfer to the power divider / combiner body is reduced through the isolated air, thereby solving the problem that the existing power divider / combiner body is installed outdoors and is easily prone to rapid increase in internal temperature under direct sunlight.

[0023] Further, a circular hole is provided on the extension block, and internal threads are provided at both ends of the circular hole. Retaining rings are installed in both ends of the circular hole, and hemispheres are installed in the retaining rings. A spring is installed between the two hemispheres.

The extension block is inserted in the gap between the edge body and the upper bottom surface of the slot, and the hemisphere on the upper side is matched in the deep hole, and the hemisphere on the lower side is matched in the through hole of the edge body.

[0024] During installation, the extension block is inserted into the card slot, and the hemisphere is used to realize the limited installation between the extension block and the lower shell, thereby realizing the rapid splicing of the components.

[0030] When the power divider / combiner body needs to dissipate heat, the motor drives the rotating part to rotate through the transmission assembly, and the rotating part pushes the air inside the arc groove to flow to one side of the fan-shaped hole and is discharged through the cylinder installed on the outside;

[0031] As the air flow speed inside the arc-shaped slot increases, the air inside the chamber formed between the power divider / combiner body and the outer shell enters the arc-shaped slot through the strip slot and is discharged;

[0032] The external air enters the chamber through the air inlet groove and the through groove in turn, and the incoming air flows along the second guide groove and the first guide groove, increasing the contact area with the outer shell of the power divider / combiner body, thereby improving the heat exchange effect.

[0033] The present invention has the following beneficial effects:

[0034] (1) The present invention protects the power divider / combiner body by installing the outer shell on the outside of the power divider / combiner body. At the same time, a chamber is formed between the power divider / combiner body and the outer shell. Both ends of the chamber are closed by end covers. In hot weather, the sun shines on the outer side of the outer shell. The heat transferred to the power divider / combiner body is reduced through the isolated air, thereby solving the problem that the existing power divider / combiner body is installed outdoors and is easily exposed to the direct sunlight, which causes the internal temperature to rise rapidly.

[0035] (2) When the power divider / combiner body of the present invention needs to dissipate heat, the motor drives the rotating part to rotate through the transmission assembly. The rotating part pushes the air inside the arc groove to flow to one side of the fan-shaped hole and is discharged through the cylinder installed on the outside. As the air flow speed inside the arc groove increases, the air inside the chamber formed between the power divider / combiner body and the outer shell enters the arc groove through the strip groove and is discharged. The external air enters the chamber through the air inlet groove and the through groove in turn. The incoming air flows along the second guide groove and the first guide groove, increasing the contact area with the outer shell of the power divider / combiner body, thereby improving the heat exchange effect.

[0036] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
