[0032] like Figure 1 and Figure 2 As shown, a floating terminal 300 of an embodiment is used to be installed in a connector 10 of a floating connector. Further, the floating terminal 300 includes a welding portion 310, a floating portion 320 and an elastic portion 330, wherein a first end of the floating portion 320 is connected to the welding portion 310, and the floating portion 320 is located between the welding portion 310 and the elastic portion 330. Further, the floating terminal 300 also includes a first fixing portion 340, wherein a second end of the floating portion 320 is connected to the elastic portion 330 through the first fixing portion 340; an opening groove 342 is provided at the bottom of the first fixing portion 340.

[0033] In this embodiment, the floating portion 320 is located in the floating gap 150, the welding portion 310 is connected to the fixed base 100, the floating portion 320 is supported by the floating base 200, and the elastic portion 330 is located in the plug slot 202 to elastically abut against the elastic terminal of the male connector when the plug slot 202 is plugged with the male connector. Specifically, the elastic portion 330 is provided with a contact point 332 and a guide portion 334.

[0034] In the above-mentioned floating connector, connector 10 and floating terminal 300, the welding portion 310 is connected to the first end of the floating portion 320, and the second end of the floating portion 320 is connected to the elastic portion 330 through the first fixing portion 340, so that the elastic portion 330 and the first fixing portion 340 can float with the floating portion 320. In addition, an opening groove 342 is provided at the bottom of the first fixing portion 340. When the connector 10 is plugged into the male connector, the elastic portion 330 undergoes elastic deformation. The first fixing portion 340 is added to the design, so that the floating terminal 300 has a better elastic deformation effect. Under limited space conditions, the length of the elastic arm of the floating terminal 300 is structurally extended, so that the floating terminal 300 has a larger elastic deformation amount and better elastic performance, even if the floating terminal 300 has a larger compression amount without fatigue; the opening groove 342 is provided at the bottom of the first fixing portion 340, which effectively reduces the antenna effect and adjusts the impedance, thereby improving the high-frequency performance of the connector.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the floating portion 320 includes a first connecting portion 322, a first elastic arm 323, a deformation portion 324, a second elastic arm 325 and a second connecting portion 326 which are connected in sequence, the first connecting portion 322 and the second connecting portion 326 are arranged opposite to each other and there is a first gap 3222, the first elastic arm 323 and the second elastic arm 325 are arranged opposite to each other and there is a second gap 3224, the deformation portion 324 has a floating groove 102, the first gap 3222 is connected to the floating groove 102 through the second gap 3224, so that the floating portion 320 has better floating performance.

[0036] In this embodiment, the floating portion 320 is R-shaped. Further, the first connecting portion 322, the first elastic arm 323, the deformable portion 324, the second elastic arm 325 and the second connecting portion 326 are an integrally formed structure. In other embodiments, the first connecting portion 322, the first elastic arm 323, the deformable portion 324, the second elastic arm 325 and the second connecting portion 326 can also be formed separately and fixedly connected together by welding.

[0037] like Figure 2 and Figure 3As shown, in one embodiment, the width of the first gap 3222 is greater than the width of the second gap 3224, so that the floating portion 320 has a better floating performance. In this embodiment, the width of the first gap 3222 is the dimension parallel to the V direction; the width of the second gap 3224 is the dimension parallel to the W direction.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the width of the first gap 3222 decreases toward the second gap 3224, so that the width of the first gap 3222 adjacent to the second gap 3224 is smaller than the width away from the second gap 3224, thereby allowing the floating portion 320 to have better floating performance.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the end of the first fixed portion 340 connected to the floating portion 320 is the first connection stop end 341, and the end of the first fixed portion 340 connected to the elastic portion 330 is the second connection stop end 343.

The end surface of the first connection stop end 341 and the end surface of the second connection stop end 343 are parallel to the extension direction of the opening slot 342, so that the first fixed portion 340 has better elastic deformation performance when deforming with the elastic portion 330, thereby making the floating portion 320 have better floating performance, and at the same time, the length of the elastic arm of the floating terminal 300 is extended under limited space conditions, thereby making the elastic performance of the elastic portion 330 better under greater elastic action. In this embodiment, the extension direction of the opening slot 342 is the X direction. Furthermore, the width X1 of the first connection stop end 341 and the width X2 of the second connection stop end 343 are both smaller than the extension length X3 of the opening groove 342 , so that the first fixing portion 340 has better elastic deformation performance.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the first fixing portion 340 is further provided with a hollow hole 345 to adjust the impedance of the floating terminal.

The first interdigital protrusion 320a and the second interdigital protrusion 340a are arranged opposite to each other, thereby reducing the inductance and impedance of the floating terminal 300.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the floating terminal 300 further includes a second fixing portion 350 , and the second fixing portion 350 is connected to the welding portion 310 .

[0044] Compared with the prior art, the present invention has at least the following advantages:

[0045] 1. The above-mentioned floating terminal 300 has a welding portion 310 connected to a first end of the floating portion 320, and a second end of the floating portion 320 is connected to the elastic portion 330 through a first fixing portion 340, so that the elastic portion 330 and the first fixing portion 340 can float with the floating portion 320. In addition, an opening groove 342 is provided at the bottom of the first fixing portion 340. When the connector 10 is plugged into the male connector, the elastic portion 330 undergoes elastic deformation. The first fixing portion 340 is added to the design, so that the floating terminal 300 has a better elastic deformation effect. Under limited space conditions, the length of the elastic arm of the floating terminal 300 is structurally extended, so that the floating terminal 300 has a larger elastic deformation amount and better elastic performance, so that the floating terminal 300 does not fatigue even if it has a larger compression amount.

[0046] 2. An opening slot 342 is provided at the bottom of the first fixing portion 340 to effectively reduce the antenna effect and adjust the impedance, thereby improving the high-frequency performance of the connector.
