Low-loss coupler

[0023] Example 1:

[0024] Such as Figure 1 to Figure 5 The shown low-loss coupler includes a coupler body 4 with three plugs, the coupler body 4 is square, and the three plugs are a first plug 1, a second plug 2, and a third plug. The plug 3, the first plug 1, the second plug 2, and the third plug 3 are respectively located on one side surface of the coupler body 4, and the first plug 1 and the third plug 3 are respectively located on opposite sides of the coupler body 1. The distance between the second plug 2 and the first plug 1 is smaller than the distance between the second plug 2 and the third plug 3; further comprising a first end cover 5, a second end cover 6, the first end The cover 5 is composed of a first connecting block 51 and a second connecting block 52 that are at right angles to each other. The first connecting block 51 is provided with a first through hole 7, and the inner diameter of the first through hole 7 is larger than the The outer diameter of the first pl

[0025] Example 2:

[0026] Such as Figure 1 to Figure 5 In the low-loss coupler shown in Embodiment 1, the thickness of the first connecting block 51 is greater than the length of the first plug 1; the thickness of the second connecting block 52 is greater than that of the second plug 2. length. The linear protrusion 11 is located on the first connecting block 51, and the long axis of the linear protrusion 11 is perpendicular to the axis of the first through hole 7. It also includes a rubber band 10. The first end cover 5 and the second end cover 6 are both connected to the coupler body 4 through the rubber band 10. A layer of sponge is laid on the inner walls of the first through hole 7, the second through hole 9, and the U-shaped groove 8.
