Description

Technical Field

[0001] The utility model relates to the technical field of power dividers, and more specifically, to a cavity power divider. Background Art

[0002] A power divider, also known as a power splitter, is a device that divides the energy of an input signal into two or more equal or unequal output energies, and can also be used in reverse to combine the energies of multiple signals into one output, in which case it can also be called a combiner. A microstrip power divider has low insertion loss, low standing wave, high isolation, and excellent amplitude and phase consistency, and is widely used in test equipment and 5G systems. In daily life, a cavity power divider is needed.

[0003] Currently, when installing the plug head and the docking head of a power divider, the plug head is generally directly inserted into the interior of the docking head. Although this can effectively install the plug head and the docking head, after long-term installation, loosening may occur between the plug head and the docking head, which will affect the normal use effect of the power divider. Moreover, dust and other impurities in the external environment may enter the interior of the power divider through the gap between the plug head and the docking head, affecting the internal components of the power divider. In addition, when installing the power divider commonly used on subways, it is generally carried out by bolts. Although this method can effectively install the power divider, the installation process is time-consuming and laborious, not only reducing the disassembly and assembly efficiency of the power divider, but also increasing the workload of the staff and reducing the overall practicality of the power divider.

[0004] Therefore, those skilled in the art have provided a cavity power divider to solve the problems raised in the above background art. Summary of the Utility Model

[0027] Please refer to Figure 1 - Figure 6 As shown in the figure, this embodiment provides a cavity power divider, including a connection plate 1, and further including:

[0028] A power divider body 2, fixedly connected to the upper surface of the connection plate 1. A plurality of docking heads 5 are provided outside the power divider body 2, and plug wire heads 6 are inserted into the interiors of the plurality of docking heads 5;

[0029] A fixed ring 7, fixedly connected to the outside of the plurality of docking heads 5. Connection sleeves 8 are fixedly connected to the outside of the plurality of plug wire heads 6, and guiding grooves for the connection sleeves 8 to move are opened in the interiors of the plurality of fixed rings 7;

[0030] A fixing component, symmetrically arranged outside the plurality of fixed rings 7 and used for fixing between the fixed rings 7 and the connection sleeves 8;

[0031] A mounting plate 15, located below the connection plate 1. A mounting block 16 is fixedly connected to the upper surface of the mounting plate 15. A positioning frame 11 is fixedly connected to the bottom of the connection plate 1, and a guiding groove for the mounting block 16 to move is opened at the bottom of the positioning frame 11;

[0032] A mounting component, respectively arranged on the front surface and the rear surface of the positioning frame 11 and used for fixing between the mounting block 16 and the positioning frame 11.

[0033] The above working principle: When it is necessary to fix and install the power divider body 2, first fix the mounting plate 15 to the required position through bolts, then sleeved the positioning frame 11 outside the mounting block 16, and then fix the mounting block 16 and the positioning frame 11 through the mounting component. At this time, the power divider body 2 can be fixed and installed, and it is convenient for the staff to disassemble, repair and replace the power divider body 2 without the staff repeatedly using tools such as bolts, effectively improving the disassembly and assembly efficiency of the power divider body 2. When it is necessary to fix the plug head 6 and the docking head 5, first insert the plug head 6 into the docking head 5. At this time, the plug head 6 will drive the connecting sleeve 8 to be inserted into the fixing ring 7 synchronously, and then fix the connecting sleeve 8 and the fixing ring 7 through the fixing component. At this time, the plug head 6 and the docking head 5 can be fixed, and the problem of loosening between the plug head 6 and the docking head 5 can be avoided. Through the cooperation between the fixing ring 7 and the connecting sleeve 8, the sealing performance between the plug head 6 and the docking head 5 can be effectively improved, so as to prevent dust and other impurities from entering the power divider body 2, effectively extending the service life of the power divider body 2, saving time and effort.

[0034] In order to effectively fix the plug head 6 and the docking head 5, the fixing component includes fixing sleeves 10 symmetrically arranged outside the plurality of fixing rings 7. A fixing rod 21 is provided inside the fixing sleeve 10. One end of the fixing rod 21 is fixedly connected with a pull ring. A contact plate 22 is fixedly connected to the outside of the fixing rod 21. A return spring 23 is sleeved on the outside of the fixing rod 21. The return spring 23 abuts between the contact plate 22 and the fixing sleeve 10. Guide grooves for the fixing rod 21 to move are opened on the contact surfaces of the fixing sleeve 10 and the fixing ring 7. Guide grooves for the fixing rod 21 to move are equally spaced inside the connecting sleeve 8. When it is necessary to fix the plug head 6 and the docking head 5, first pull the pull ring. At this time, the pull ring will drive the fixing rod 21 to move synchronously. The fixing rod 21 will drive the contact plate 22 to move synchronously. During the movement of the contact plate 22, the return spring 23 will be compressed. Then insert the plug head 6 into the docking head 5. The plug head 6 will drive the connecting sleeve 8 to move synchronously. When the connecting sleeve 8 is completely inserted into the fixing ring 7, release the pull ring. At this time, the return spring 23 resets, driving the contact plate 22 and the fixing rod 21 to move synchronously. When the fixing rod 21 is inserted into the guide groove inside the connecting sleeve 8, the connecting sleeve 8 and the fixing ring 7 can be fixed. At this time, the plug head 6 and the docking head 5 can be fixed, and the situation of loosening between the plug head 6 and the docking head 5 can be avoided, and the sealing performance between the plug head 6 and the docking head 5 can be effectively improved.

[0035] Considering that after the connection sleeve 8 is fixed to the fixed ring 7, it is necessary to further improve the sealing performance between the connection sleeve 8 and the fixed ring 7. Therefore, sealing rings 9 are adhesively attached to the outsides of multiple connection sleeves 8. Through the arrangement of the sealing rings 9, the sealing performance between the connection sleeve 8 and the fixed ring 7 can be further improved, thereby effectively preventing dust and other impurities from entering the inside of the power divider body 2 and effectively extending the service life of the power divider body 2.

[0036] In order to conveniently and effectively fix and install the power divider body 2, the installation component includes fixing plates 14 respectively arranged on the front surface and the rear surface of the positioning frame 11. Slide bars 19 are symmetrically arranged inside the fixing plates 14. Both ends of multiple slide bars 19 are fixedly connected to the front and rear inner walls of the fixing plates 14. A moving plate 18 is arranged inside the fixing plates 14. A guiding groove for the movement of the slide bars 19 is formed inside the moving plate 18. A plurality of abutting springs 20 are sleeved on the outsides of multiple slide bars 19. A plurality of abutting springs 20 all abut between the moving plate 18 and the fixing plates 14. Connecting rods 17 are symmetrically arranged on the outside of the moving plate 18. The other ends of every two connecting rods 17 are fixedly connected to a pulling plate. Plug plates 13 are fixedly connected to the opposite sides of the two moving plates 18. Guiding grooves for the movement of the plug plates 13 are formed on the contact surfaces between the fixing plates 14 and the positioning frame 11. Guiding grooves for the movement of the plug plates 13 are formed on the front surface and the rear surface of the mounting block 16. When it is necessary to fix and install the power divider body 2, first fix the mounting plate 15 to the required position through bolts. At this time, pull the pulling plate. The pulling plate will drive the connecting rods 17 to move synchronously. The connecting rods 17 will drive the moving plate 18 to move synchronously on the outsides of the slide bars 19. During the movement of the moving plate 18, the abutting springs 20 will be compressed. The moving plate 18 will also drive the plug plates 13 to move synchronously. At this time, sleeved the positioning frame 11 on the outside of the mounting block 16 and then release the pulling plate. At this time, the abutting springs 20 reset and drive the moving plate 18 to move synchronously. The moving plate 18 drives the plug plates 13 to move synchronously. When the plug plates 13 are inserted into the guiding grooves on the front surface and the rear surface of the mounting block 16, the mounting block 16 and the positioning frame 11 can be fixed. At this time, the power divider body 2 can be fixed and installed, and at the same time, it is convenient for the staff to disassemble, inspect and replace the power divider body 2 without the staff repeatedly using tools such as bolts, effectively improving the disassembly and assembly efficiency of the power divider body 2.

[0037] In order to effectively improve the fixing effect between the positioning frame 11 and the mounting block 16, cross insertion plates 12 are symmetrically arranged at the bottom of the positioning frame 11, and a guiding groove for the activity of the cross insertion plates 12 is formed on the upper surface of the mounting block 16. Through the arrangement of the cross insertion plates 12, on the one hand, the fixing effect between the positioning frame 11 and the mounting block 16 can be effectively improved, and on the other hand, it is convenient for the staff to perform docking installation processing between the positioning frame 11 and the mounting block 16.

[0038] In addition, in order to effectively protect the power divider body 2 when it is not needed, a plurality of rubber connecting bands 3 are fixedly connected to the upper surface of the power divider body 2, and the other ends of the plurality of rubber connecting bands 3 are fixedly connected with rubber protection plugs 4. When the power divider body 2 does not need to be used, only need to insert the rubber protection plug 4 into the inside of the docking head 5, and then use the fixing component to fix the rubber protection plug 4. At this time, the power divider body 2 can be effectively protected by the rubber protection plug 4, so as to prevent dust and other impurities in the external environment from entering the inside of the power divider body 2.
