[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] Referring to Figure 1-7 As shown in the figure, a micro-loss power splitter includes an installation box body 1. The inner bottom surface of the installation box body 1 is fixedly connected with an installation plate 2. Four corner positions on the upper surface of the installation plate 2 are fixedly connected with fixed feet 3. This design of the fixed feet 3 ensures the stability and reliability of the power splitter board 4, preventing damage or performance degradation caused by vibration or impact. Above the installation plate 2, a power splitter board 4 is fixedly connected through the fixed feet 3. In the middle of the upper surface of the power splitter board 4, a power splitter rod 6 is provided. The power splitter rod 6 can evenly distribute the input signal to each output end 7, ensuring that each port receives the same intensity signal. This design helps to avoid signal distortion and attenuation. One side of the power splitter rod 6 is fixedly connected with an input end 5, and the other side of the power splitter rod 6 is fixedly connected with at least two groups of output ends 7. Four groups of insertion slots 8 are opened on the surface of the power splitter board 4 at the positions of the input end 5 and the two groups of output ends 7. Four groups of clamping slots 9 are opened inside the four groups of insertion slots 8. Connection terminals 10 are provided at the positions of the input end 5 and the two groups of output ends 7. Through the modular design of the installation box body 1 and the connection terminals 10, the power splitter can be easily installed in various systems, improving the installation efficiency and convenience.

[0024] Specifically, the connection terminal 10 includes a fixed plate 1001. A pin hole 1007 is penetrated through the middle of the fixed plate 1001. Four groups of insertion pins 1004 are fixedly connected to the side of the fixed plate 1001 close to the power splitter board 4.

[0025] Preferably, a clamping block 1005 is fixedly connected to one side of the four groups of insertion pins 1004 close to the pin hole 1007. The insertion pins 1004 are slidably connected inside the insertion slots 8, and the clamping block 1005 is clamped inside the clamping slot 9. The clamping design of the clamping block 1005 and the clamping slot 9 ensures the stability and reliability of the connection terminal 10, reducing performance problems caused by loosening or falling off.

[0026] Preferably, connection columns 1006 are fixedly connected to both the upper and lower sides of the pin holes 1007 on the side of the fixed plate 1001 close to the power splitter board 4. A sealing gasket 1003 is fixedly connected to the outer periphery of the pin 1004 on the side of the fixed plate 1001 close to the power splitter board 4. A threaded column 1002 is fixedly connected to the side of the fixed plate 1001 away from the mounting box body 1.

[0027] Specifically, jacks 13 are provided at the positions of the input end 5 and the two output ends 7 on the outer side of the mounting box body 1. A sealing groove 11 adapted to the sealing gasket 1003 is provided on the outer periphery of the jacks 13 on the outer side of the mounting box body 1. The design of the sealing gasket 1003 and the sealing groove 11 ensures the sealing between the connection terminal 10 and the mounting box body 1, prevents the intrusion of external factors such as dust and moisture, and improves the stability and reliability of the power splitter.

[0028] It is worth noting that pins 12 are fixedly connected to both the middle left and middle right of the power splitter board 4. Two pins are provided on the left side of the pins 12 and are respectively fixedly connected to the two output ends 7. One pin is provided on the right side of the pins 12 and is fixedly connected to the input end 5. Through the dual signal conduction method of the pins 12 and the connection columns 1006, it is possible to avoid the loose connection between the connection column 1006 and the output end 7 during multiple plugging and unplugging processes and prevent the occurrence of poor contact.

[0029] Optionally, the connection terminal 10 is a DIN interface or an SMA-K interface. The above interfaces have wide compatibility and universality and can be easily connected to various devices and systems.

[0030] Working principle: When in use, insert the connection terminal 10 into the jack 13. At this time, the pin 1004 will be inserted onto the power splitter board 4 along the insertion slot 8. After pushing the connection terminal 10 to the end until a "click" sound is heard, the clamping block 1005 will be clamped inside the clamping groove 9, indicating that the installation is completed at this time. At this time, the sealing gasket 1003 will be inserted into the sealing groove 11 to seal the connection position between the connection terminal 10 and the mounting box body 1. The connection columns 1006 on the upper and lower sides will be clamped on the power splitter board 4, and the pins 12 will extend through the jack 13 and into the threaded column 1002.
