Further, referring to fig. 1 to 9, as an embodiment of the shielded connector provided by the present invention, the conductive spring ring 5 has a shaft portion 51 for abutting against the inner wall of the fourth conductive cylinder 14. In this way, the rod portion 51 is not likely to slip when it abuts on the fourth cylindrical conductive member 14.

Specifically, in one embodiment, the extending direction of the rod portion 51 is the same as the extending direction of the conductive sleeve 4. Therefore, when the fourth conductive cylinder 14 is sleeved on the conductive spring ring 5 toward 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 fourth conductive cylinder 14.

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 9, as an embodiment of the shielded connector provided by the present invention, the shielded connector further includes a fifth conductive cylinder 15; the fifth conductive cylinder 15 is sleeved on the fourth conductive cylinder 14, the fifth conductive cylinder 15 is in threaded connection with the fourth conductive cylinder 14, the fifth conductive cylinder 15 and the fourth conductive cylinder 14 are sealed through a first sealing ring 71, and the fourth conductive cylinder 14 and the first conductive cylinder 11 are sealed through a second sealing ring 72. Thus, the fifth conductive cylinder 15 is sleeved on the fourth conductive cylinder 14, so that water is not easy to permeate into the space between the fifth conductive cylinder 15 and the fourth conductive cylinder 14; the fifth conductive cylinder 15 and the fourth conductive cylinder 14 are in threaded connection, so that the disassembly is very convenient, the fifth conductive cylinder 15 and the fourth conductive cylinder 14 are sealed through the first sealing ring 71, and the fifth conductive cylinder 15 and the fourth conductive cylinder 14 are prevented from being seeped; the fourth conductive cylinder 14 is sleeved on the first conductive cylinder 11, so that water is not easy to permeate into the space between the fourth conductive cylinder 14 and the first conductive cylinder 11; the fourth conductive cylinder 14 is in threaded connection with the first conductive cylinder 11, so that the disassembly is very convenient, and the fourth conductive cylinder 14 is sealed with the first conductive cylinder 11 through the second sealing ring 72, so that the fourth conductive cylinder 14 and the first conductive cylinder 11 are prevented from water seepage; the fifth conductive cylinder 15, the fourth conductive cylinder 14 and the first conductive cylinder 11 are sequentially communicated for the cable 6 to be arranged.

Specifically, in one embodiment, the device further comprises a base and a second conductive cylinder 12 arranged on the base; the first conductive cylinder 11 is sleeved with a third sealing ring 73; when the first conductive cylinder 11 is inserted into the second conductive cylinder 12, the third seal ring 73 seals a gap between the first conductive cylinder 11 and the second conductive cylinder 12. Thus, when the first conductive cylinder 11 is mounted on the seat body, only the first conductive cylinder 11 needs to be inserted into the second conductive cylinder 12; the third sealing ring 73 seals a gap between the first conductive cylinder 11 and the second conductive cylinder 12 to prevent water from permeating between the first conductive cylinder 11 and the second conductive cylinder 12.

Specifically, in one embodiment, the housing is provided with a fourth sealing ring 74 disposed outside the second conductive cylinder 12. In this manner, passing the second conductive cylinder 12 through the mounting hole in the equipment enclosure and abutting the fourth sealing ring 74 against the enclosure prevents moisture from penetrating into the interior of the equipment enclosure from the mounting hole.

Thus, when the third conductive cylinder 13 is connected to the second conductive cylinder 12, only the third conductive cylinder 13 is required to be sleeved on the second conductive cylinder 12, and then the sliding block 132 is required to slide into the sliding groove 121; because the chute 121 is the chute 121 that is spiral extension along the second conductive cylinder 12, when rotating the third conductive cylinder 13, the slider 132 slides along the chute 121 and can drive the third conductive cylinder 13 to move along the second conductive cylinder 12 so as to be taut each other, and the slider 132 and the third conductive cylinder 13 are fixed and separated very conveniently, and only the third conductive cylinder 13 needs to be rotated.

Specifically, in one embodiment, the number of the sliding grooves 121 is multiple, and multiple sliding grooves 121 are arranged in parallel; the number of the sliding blocks 132 is plural, and the plural sliding blocks 132 correspond to the plural sliding grooves 121 one by one. Thus, the plurality of sliding blocks 132 and the plurality of sliding grooves 121 are matched with each other, so that the third conductive cylinder 13 is more stable in the rotating process.

Further, referring to fig. 1 to fig. 9, as an embodiment of the shielded connector provided by the present invention, the sliding block 132 is detachably fixed on the third conductive cylinder 13. In this way, the slider 132 and the third conductive cylinder 13 can be independently processed.

Thus, the male conductive terminals 822 are inserted on the male rubber core 812, and the male rubber core 812 insulates the male conductive terminals 822; the female conductive terminals 821 are inserted on the female rubber core 811, and the female rubber core 811 insulates the female conductive terminals 821; the cable 9 supplies power to the female conductive terminal 821, and the cable 6 supplies power to the male conductive terminal 822; the conductive sleeve 4 binds the shielding wire in the cable 6 (binding: the conductive sleeve 4 is in conductive contact with the shielding wire, and the conductive sleeve 4 binds the shielding wire on the cable 6) on the cable 6, when the cable 6 needs to be grounded, only the external ground wire needs to be connected with the conductive sleeve 4, and the grounding is very convenient.

Therefore, the first limit boss is limited between the first annular boss 8221 and the second annular boss 8222, so that the firmness of the relative position between the male conductive terminal 822 and the male rubber core 812 is kept, and the electric leakage is reduced.

Specifically, in one embodiment, the first limit boss ring is disposed outside the male conductive terminal 822. Thus, no matter how the male conductive terminal 822 rotates, the first limit boss can always limit the male conductive terminal 822.

Specifically, in one embodiment, the female conductive terminal 821 is provided with a third annular boss 8211 and a fourth annular boss 8212 at intervals, and the female rubber core 811 has a second limit boss clamped between the third annular boss 8211 and the fourth annular boss 8212. Therefore, the third limiting boss is limited between the third annular boss 8211 and the fourth annular boss 8212, so that the firmness of the relative position between the female conductive terminal 821 and the female rubber core 811 is kept, and the electric leakage is reduced.

Specifically, in one embodiment, the second limit boss ring is disposed outside the female conductive terminal 821. Thus, no matter how the female conductive terminal 821 rotates, the first limit boss can always limit the female conductive terminal 821.

Specifically, in one embodiment, the male conductive terminal 822 has a first wire insertion cavity into which the wire core of the cable 6 is inserted.
