Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 8, the shielding system of the present invention will now be described. The shielding system comprises: a sleeve-shaped conductive sleeve 4 (tube: hollow tubular object), a conductive spring ring 5 annularly arranged on the conductive sleeve 4, and a first conductive cylinder 11; the conductive sleeve 4 has a wire passing hole 41 through which the cable 6 passes; the wire passing hole 41 has a conductive inner wall for contacting with the shield wire on the cable 6; the first conductive cylinder 11 is sleeved on the conductive spring ring 5, and the conductive spring ring 5 is conductively connected with the first conductive cylinder 11.

Thus, the conductive sleeve 4 is sleeved on the cable 6 through the wire passing hole 41, and the shielding wire on the cable 6 is in contact with the conductive inner wall of the wire passing hole 41 (for example, the conductive sleeve 4 is sleeved on the shielding wire); the conductive sleeve 4 is sleeved with a conductive spring ring 5, so that charges on a shielding wire on the cable 6 are transmitted to the conductive spring ring 5 through the conductive sleeve 4; the conductive spring ring 5 is in conductive connection with the first conductive cylinder body 11, the first conductive cylinder body 11 is grounded through the conductive spring ring 5, and the grounding is very convenient and only the first conductive cylinder body 11 is required to be sleeved on the conductive spring ring 5; and the first conductive cylinder 11 can protect the conductive spring ring 5.

Specifically, in one embodiment, the wire through hole 41 extends in a straight direction. Thus, the cable 6 can be easily inserted into the wire passing hole 41.

Specifically, in one embodiment, the cross-section of the wire through hole 41 is circular. Thus, the cable 6 is generally circular, and it is easy to pass the circular cable 6 through the circular wire passing hole 41.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, the conductive coil 5 is spirally wound around the conductive sleeve 4. Thus, the spiral conductive spring ring 5 can be conveniently unfolded and folded to adapt to the conductive sleeves 4 with different outer diameters.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, the conductive spring ring 5 has a shaft portion 51 for abutting against the inner wall of the first conductive cylinder 11. Thus, the rod portion 51 is abutted against the first conductive cylindrical body 11 and is not easily slipped.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system of the present invention, the extending direction of the rod portion 51 is the same as the extending direction of the conductive sleeve 4. Therefore, when the first conductive cylinder 11 is sleeved on the conductive spring ring 5 towards the extending direction of the conductive sleeve 4 and contacts with the rod portion 51, the rod portion 51 can guide the sliding of the first conductive cylinder 11.

In particular, in one embodiment, the number of conductive sleeves 4 is two. In this way, the two conductive sleeves 4 can shunt the cable 6; the wire through hole 41 of each conductive sleeve 4 can be respectively passed through the cable 6.

In particular, in one embodiment, two conductive sleeves 4 are arranged in parallel. In this way, mutual interference of the cables 6 in the two conductive sleeves 4 is reduced.

Specifically, in one embodiment, the conductive sleeve 4 is a unitary piece of copper/steel; or the conductive spring ring 5 is a copper/steel integral piece. Thus, the copper/steel has good conductivity and toughness.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, the shielding system further includes: a second conductive cylinder 12, a third conductive cylinder 13 detachably sleeved on the second conductive cylinder 12, and a fourth conductive cylinder 14 sleeved and slidably arranged on the second conductive cylinder 12; the first conductive cylinder 11 is sleeved on the second conductive cylinder 12, and the first conductive cylinder 11 is in threaded connection with the second conductive cylinder 12; the third conductive cylinder 13 is detachably fixed on the fourth conductive cylinder 14; the second conductive cylinder 12 is provided with a first conductive stopping portion 121, the fourth conductive cylinder 14 is provided with a second conductive stopping portion 141, and the conductive elastic sheet 2 is clamped between the first conductive stopping portion 121 and the second conductive stopping portion 141. Thus, after the third conductive cylinder 13 is sleeved on the second conductive cylinder 12, the cable 6 (or the power supply terminal) can pass through the second conductive cylinder 12 and the third conductive cylinder 13; when the fourth conductive cylinder 14 is fixed on the third conductive cylinder 13, the conductive elastic sheet 2 is clamped between the first conductive stopping portion 121 and the second conductive stopping portion 141; the first conductive stopper 121 is located on the second conductive cylinder 12, and the second conductive stopper 141 is located on the fourth conductive cylinder 14; the third conductive cylinder 13 is electrically connected with the second conductive cylinder 12 through the fourth conductive cylinder 14, the second conductive stop portion 141, the conductive elastic sheet 2 and the first conductive stop portion 121 in sequence; the conductive elastic sheet 2 can ensure the stability of the conductive connection between the first conductive stopping portion 121 and the second conductive stopping portion 141.

Specifically, in one embodiment, the first conductive cylinder 11, the second conductive cylinder 12, the third conductive cylinder 13, the fourth conductive cylinder 14, the first conductive stopper 121, the second conductive stopper 141, the annular gasket 3, and the conductive elastic sheet 2 are each a copper/steel integrated piece.

Specifically, in one embodiment, the first conductive stopper 121 is annular, and the first conductive stopper 121 is disposed on the outer wall of the second conductive cylinder 12. Thus, when the conductive elastic sheet 2 rotates relative to the second conductive cylinder 12, the conductive contact between the conductive elastic sheet 2 and the first conductive stopping portion 121 is not easily affected.

Specifically, in one embodiment, the second conductive stopper 141 is annular, and the second conductive stopper 141 is disposed on the inner wall of the fourth conductive cylinder 14. Thus, when the conductive elastic piece 2 rotates relative to the second conductive cylinder 12, the conductive contact between the conductive elastic piece 2 and the second conductive stopping portion 141 is not easily affected.

Specifically, in one embodiment, the second conductive cylinder 12 is sleeved with an annular gasket 3, and the annular gasket 3 is clamped between the conductive elastic sheet 2 and the first conductive stopper 121. So, annular gasket 3 can be effectively supported when electrically conductive shell fragment 2 deforms, be convenient for electrically conductive shell fragment 2 when taking place deformation and form stable electrically conductive connection between annular gasket 3.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, the conductive elastic sheet 2 is in an arc shape, and the conductive elastic sheet 2 is sleeved on the outer side of the second conductive cylinder 12. Thus, the relative position between the conductive elastic sheet 2 and the second conductive cylinder 12 is more stable.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system of the present invention, the conductive elastic sheet 2 is corrugated in the extending direction of the second conductive cylinder 12. Thus, when the fourth conductive cylinder 14 moves along the second conductive cylinder 12 and the first conductive stopping portion 121 and the second conductive stopping portion 141 extrude the conductive elastic sheet 2, the wavy conductive elastic sheet 2 and the first conductive stopping portion 121/the second conductive stopping portion 141 have a plurality of supporting points, which is beneficial to ensuring the contact stability between the conductive elastic sheet 2 and the first conductive stopping portion 121/the second conductive stopping portion 141.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, an annular gasket 3 is sleeved on the second conductive cylinder 12, and the annular gasket 3 is clamped between the conductive elastic sheet 2 and the first conductive stopping portion 121. So, annular gasket 3 can be effectively supported when electrically conductive shell fragment 2 deforms, be convenient for electrically conductive shell fragment 2 when taking place deformation and form stable electrically conductive connection between annular gasket 3.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, the shielding system further includes a fifth conductive cylinder 15; the fifth conductive cylinder 15 is sleeved on the first conductive cylinder 11, and the fifth conductive cylinder 15 is in threaded connection with the first conductive cylinder 11. Thus, the first conductive cylinder 11 and the fifth conductive cylinder 15 can be fixed/separated from each other with respect to the second conductive cylinder 12, so that the external component can be mounted in the first conductive cylinder 11/the fifth conductive cylinder 15 and then mounted on the second conductive cylinder 12 for matching.

Further, referring to fig. 1 to 8, as an embodiment of the shielding system provided by the present invention, a sliding groove 131 surrounding the third conductive cylinder 13 and extending in a spiral manner is formed on the arc-shaped side surface of the third conductive cylinder 13, and a sliding block 142 for sliding in the sliding groove 131 is disposed on the inner wall of the fourth conductive cylinder 14. Thus, when the fourth conductive cylinder 14 is connected to the third conductive cylinder 13, the fourth conductive cylinder 14 is only required to be sleeved on the third conductive cylinder 13, and then the sliding block 142 is slid into the sliding groove 131; because the chute 131 is the chute 131 which extends spirally along the third conductive cylinder 13, when the fourth conductive cylinder 14 is rotated, the sliding block 142 slides along the chute 131 to drive the fourth conductive cylinder 14 to move along the third conductive cylinder 13 so as to be mutually tensioned, the sliding block 142 and the fourth conductive cylinder 14 are very convenient to fix and separate, and only the fourth conductive cylinder 14 needs to be rotated.

Specifically, in one embodiment, the number of the sliding grooves 131 is multiple, and the multiple sliding grooves 131 are arranged in parallel; the number of the sliding blocks 142 is plural, and the plurality of sliding blocks 142 correspond to the plurality of sliding grooves 131 one to one. Thus, the plurality of sliding blocks 142 and the plurality of sliding grooves 131 are matched with each other, so that the fourth conductive cylinder 14 can be more stable in the rotating process.

Specifically, in one embodiment, the slide 142 is detachably fixed to the fourth conductive cylinder 14. In this way, the slider 142 and the fourth conductive cylinder 14 can be independently processed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
