The second ring piece 200 includes a third cross-section 210 and a fourth cross-section 220, which are respectively located at the two free ends of the second ring piece 200 opposite the first ring piece 100. The first cross-section 110 and the third cross-section 210 are connected by a snap-fit ​​connection, while the second cross-section 120 and the fourth cross-section 220 are connected by a snap-fit ​​connection. The connection position is set at a position opposite the first ring piece 100 and the second ring piece, saving space. The first cross-section 110 and the third cross-section 210, and the second cross-section 120 and the fourth cross-section 220 are in close contact, ensuring good sealing of the grounding connector.

[0036] Furthermore, one of the first section 110 and the third section 210 is provided with a first protrusion 130, and the other is provided with a first locking groove 230; one of the second section 120 and the fourth section 220 is provided with a second protrusion 140, and the other is provided with a second locking groove 240, the first protrusion 130 is adapted to the shape of the first locking groove 230, the second protrusion 140 is adapted to the shape of the second locking groove 240, the first protrusion 130 and the first locking groove 230 are connected by a snap-fit ​​connection, and the second protrusion 140 and the second locking groove 240 are connected by a snap-fit ​​connection to connect the first ring piece 100 and the second ring piece 200.

[0037] For example, in one embodiment, the first cross-section 110 is provided with a first protrusion 130, and the third cross-section 210 is provided with a first engaging groove 230; the second cross-section 120 is provided with a second protrusion 140, and the fourth cross-section 220 is provided with a second engaging groove 240. In another embodiment, the first cross-section 110 is provided with a first protrusion 130, and the third cross-section 210 is provided with a first engaging groove 230; the second cross-section 120 is provided with a second engaging groove 240, and the fourth cross-section 220 is provided with a second protrusion 140. In yet another embodiment, the first cross-section 110 is provided with a first engaging groove 230, and the third cross-section 210 is provided with a first protrusion 130; the second cross-section 120 is provided with a second protrusion 140, and the fourth cross-section 220 is provided with a second engaging groove 240. In yet another embodiment, the first cross-section 110 is provided with a first engaging groove 230, and the third cross-section 210 is provided with a first protrusion 130; the second cross-section 120 is provided with a second engaging groove 240, and the fourth cross-section 220 is provided with a second protrusion 140.

[0038] Optionally, the first protrusion 130, the first engaging groove 230, the second protrusion 140, and the second engaging groove 240 are all isosceles trapezoidal. The isosceles trapezoidal shapes of the first protrusion 130, the first engaging groove 230, the second protrusion 140, and the second engaging groove 240 are simple to set up; the hypotenuse of the isosceles trapezoid facilitates the assembly of the first protrusion 130 with the first engaging groove 230, and the second protrusion 140 with the second engaging groove 240; and the top and bottom sides of the isosceles trapezoid ensure good sealing between the first protrusion 130 and the first engaging groove 230, and the second protrusion 140 and the second engaging groove 240.

[0039] It should be noted that the length of the top side of the isosceles trapezoid is smaller than the length of the bottom side. If the first protrusion 130 is located on the first ring piece 100 and the first locking groove 230 is located on the second ring piece 200, the top side of the isosceles trapezoid of the first protrusion 130 is connected to the first ring piece 100; the bottom side of the isosceles trapezoid of the first locking groove 230 is located at the bottom of the first locking groove 230 on the second ring piece 200; if the second protrusion 140 is located on the first ring piece 100 and the second locking groove 240 is located on the second ring piece 200, the top side of the isosceles trapezoid of the second protrusion 140 is connected to the first ring piece 100; the bottom side of the isosceles trapezoid of the second locking groove 240 is located at the bottom of the second locking groove 240 on the second ring piece 200. The length of the top side of the isosceles trapezoid is smaller than the length of the bottom side. If the first protrusion 130 is located on the second ring piece 200, the first locking groove 230 is located on the first ring piece 100, and the top side of the isosceles trapezoid of the first protrusion 130 is connected to the second ring piece 200; the bottom side of the isosceles trapezoid of the first locking groove 230 is located at the bottom of the first locking groove 230 on the first ring piece 100; if the second protrusion 140 is located on the second ring piece 200, the second locking groove 240 is located on the first ring piece 100, and the top side of the isosceles trapezoid of the second protrusion 140 is connected to the second ring piece 200; the bottom side of the isosceles trapezoid of the second locking groove 240 is located at the bottom of the second locking groove 240 on the first ring piece 100.

[0040] In order to adapt to the shape of the shielded cable, the first ring piece 100 and the second ring piece 200 are ring pieces with the same appearance.

[0041] Furthermore, the ground connection piece further includes an extension piece 300 , which is connected to the side of the second ring piece 200 facing away from the first ring piece 100 , so as to facilitate the installation and fixation of the second ring edge.

[0042] Furthermore, the first ring piece 100 , the second ring piece 200 and the extension piece 300 are all symmetrical shapes, and have the same central axis of symmetry.

[0043] Optionally, the second ring piece 200 and the extension piece 300 are integrally formed. Integral forming is simple to process.
