[0033] Embodiment 1

[0034] like Figure 1 As shown, a new type of connector includes a connecting wire 3 and a plug connector 5. One end of the connecting wire 3 is connected to the connecting member 2. One end of the plug connector 5 is provided with a dustproof mechanism 1. The dustproof mechanism 1 and the connecting member 2 are connected by a

[0035] The magnetic attraction component 4 magnetically attracts the card and realizes electrical connection at the same time.

[0036] Furthermore, the connector 5 includes but is not limited to various interface forms such as type-a and type-c. A flexible layer may be provided on one side of the dustproof mechanism 1 that is in contact with the connector 5. The flexible layer may be made of a material such as sponge or silicone.

[0037] When in use, the connector 5 is pre-inserted into the device to be connected, and the connecting line 3 is pre-connected to the power supply. When connection is needed, the connecting piece 2 and the dustproof mechanism 1 only need to be brought close to each other to connect the connecting line 3 and the connector 5. The operation is simple and convenient, and it can effectively prevent the interface from being damaged due to repeated plugging and unplugging of the connector 5. At the same time, the connector 5 is connected to the dustproof mechanism 1, which can seal the plug-in gap between the connector 5 and the connected device to prevent dust and the like from entering the interface through the gap and affecting the stability of the connection.

[0038] Embodiment 2

[0039] Based on the first embodiment, Figure 1-5 As shown, the magnetic attraction component 4 includes a magnetic attraction plate 9 and an electromagnetic sheet 18. A positioning rod 19 is fixedly connected to the center of one side of the connecting member 2 that is in contact with the dustproof mechanism 1. The electromagnetic sheet 18 is fixedly connected to the end of the positioning rod 19 that is away from the connecting member 2. The dustproof mechanism 1 is provided with a positioning hole 11 that is compatible with the positioning rod 19. The magnetic attraction plate 9 is embedded in the bottom of the positioning hole 11, and the electromagnetic sheet 18 is electrically connected to the connecting line 3.

[0040] Furthermore, the edge of one end of the positioning rod 19 away from the connecting member 2 may be provided with a certain curvature, so as to facilitate the insertion between the positioning rod 19 and the positioning hole 11 .

[0041] When in use, by electrically connecting the electromagnetic sheet 18 to the connecting wire 3, the electromagnetic sheet 18 will become magnetic when there is current inside the connecting wire 3, so that the magnetic sheet 18 can attract the magnetic plate 9, so that the magnetic component 4 can insert the positioning rod 19 into the positioning hole 11 through the suction force between the electromagnetic sheet 18 and the magnetic plate 9 when the connecting part 2 and the dustproof mechanism 1 are close to each other, thereby realizing the active approach and attraction between the connecting part 2 and the dustproof mechanism 1, and the insertion of the positioning rod 19 can effectively avoid the situation in which a gap appears on the attraction surface of the connecting part 2 and the dustproof mechanism 1 due to the tilt of the connecting part 2 during the magnetic attraction process, thereby affecting the connection quality.

[0042] like Figure 1-5 As shown, a contact electrode 14 is provided on the side end surface of the connecting member 2 , and the contact electrode 14 is electrically connected to the electromagnetic sheet 18 .

[0043] Furthermore, the contact electrodes 14 may be provided in multiple groups and arranged symmetrically around the side end surface of the connecting member 2 .

[0044] During use, in order to facilitate the separation of the dustproof mechanism 1 and the connector 2, a contact electrode 14 is provided on the side end face of the connector 2. Since the dustproof mechanism 1 is relatively thin, the connector 2 needs to be held when the device is disconnected. In order to prevent the magnetic suction component 4 from having excessive suction force, which may cause the connector 5 to be separated from the connecting device, a contact electrode 14 is provided. When the connector 2 is held, the contact electrode 14 receives a contact signal, thereby disconnecting the electromagnetic sheet 18 from the connecting line 3, so that the magnetism of the electromagnetic sheet 18 disappears, and the dustproof mechanism 1 and the connector 2 can be conveniently separated, and the same as the user's usage habits. At the same time, the contact electrodes 14 can be provided with multiple groups of symmetrical settings, such as two groups symmetrically provided, which can be triggered only when multiple groups of contact electrodes 14 receive contact signals, thereby avoiding disconnection caused by accidental touching of the contact electrodes 14.

[0045] like Figure 1-4 As shown, a dustproof guard plate 27 is rotatably embedded on the side of the dustproof mechanism 1 that contacts the connector 2 through a rotating ring 7, and a plurality of groups of plug-in ring grooves 8 are provided in the middle of the dustproof guard plate 27 around the positioning hole 11, and an annular pole piece 12 is provided at the bottom of the plug-in ring groove 8, and the annular pole pieces 12 are separated by a partition plate 13.

[0046] like Figure 1-7 As shown, one end of the connector 2 that fits with the dustproof mechanism 1 is elastically connected to an anti-magnetic attraction plate 16 through a rubber ring 15, and an elastic contact 21 is embedded on one side of the connector 2 that fits with the dustproof mechanism 1. The elastic contact 21 is electrically connected to the connecting line 3, and the anti-magnetic attraction plate 16 has plug-in slots 17 that are compatible with the elastic contact 21 around both sides of the positioning rod 19.

[0047] Furthermore, a power supply pin 6 is provided inside the connector 5 , and the power supply pin 6 is electrically connected to the annular pole piece 12 . The anti-magnetic attraction shield 16 is provided with a hole adapted to the positioning rod 19 .

[0048] During use, when the dustproof mechanism 1 and the connector 2 are attracted, the dustproof guard plate 27 presses the anti-magnetic attraction guard plate 16, so that the rubber ring 15 is compressed, and the elastic contact 21 is extended out of the surface of the plug-in slot 17, and the elastic contact 21 is inserted into the inside of the plug-in ring slot 8 and fits with the annular pole piece 12, so that the connector 2 and the dustproof mechanism 1 are electrically connected, so that the connecting line 3 and the plug-in connector 5 are electrically connected, so that the electrical connection between the plug-in connector 5 and the connecting line 3 is realized through the magnetic attraction component 4, and the dustproof guard plate 27 is rotatably connected to the dustproof mechanism 1, and the annular pole piece 12 is arranged in a ring shape, so that when the connector 2 is used, even if the connector 2 rotates, the elastic contact 21 and the annular pole piece 12 can maintain a stable electrical connection state, thereby effectively avoiding the situation in which the cable connection of the traditional connection device is damaged or the connection is unstable due to the rotation of the connecting line 3.

[0049] like Figure 1-9 As shown, a protective airbag 20 is provided on the side wall of the partition plate 13 , and the protective airbag 20 covers and extends to the interior of the plug-in ring groove 8 .

[0050] When in use, the plug-in ring groove 8 is not in use, and the internal space of the plug-in ring groove 8 is sealed by the protective airbag 20, thereby effectively preventing dust and other impurities from entering the plug-in ring groove 8 and affecting the connection effect between the elastic contact 21 and the annular pole piece 12. When the elastic contact 21 is inserted into the plug-in ring groove 8, the protective airbag 20 is pressed to separate toward both sides and wrap the elastic contact 21, which can also prevent dust and the like from entering the plug-in ring groove 8. The annular pole pieces 12 are separated by a partition plate 13 to prevent liquid from entering the plug-in ring groove 8 and causing a short circuit between the annular pole pieces 12.

[0051] Embodiment 3

[0052] Based on the first and second embodiments, Figure 1-7 As shown in FIG. 10 , a magnetic locking mechanism is provided inside the positioning rod 19, and the magnetic locking mechanism includes a second limit slot 22, a clamping block 25 and a first limit slot 10. The first limit slot 10 is provided on the inner wall of the positioning hole 11, and the second limit slot 22 is provided on the side end surface of the positioning rod 19. The clamping block 25 is elastically embedded in the second limit slot 22, and the clamping block 25 is clamped with the first limit slot 10.

[0053] like Figure 1-7 As shown in FIG. 10 , a sliding groove 23 is provided inside the positioning rod 19 , and a magnetic rod 26 is slidably connected inside the sliding groove 23 . A conical surface 24 is provided on the top of the magnetic rod 26 , and the conical surface 24 fits with an inclined surface of one end of the clamping block 25 .

[0054] Furthermore, the cross-section of the clamping block 25 is a parallelogram, and the cross-section of the first limiting slot 10 is a triangle, so that when the clamping block 25 extends from the inside of the second limiting slot 22, the positioning rod 19 can be inserted into the inside of the first limiting slot 10 and engage with the first limiting slot 10 and cannot be pulled out after engagement.

[0055] When in use, after the magnetic attraction plate 9 at the end of the positioning rod 19 is electrically connected to the connecting line 3, the magnetic attraction rod 26 slides inside the sliding groove 23 under the action of magnetic traction, and the clamping block 25 can be extended from the inside of the second limiting clamping groove 22 under the action of the conical surface 24. After the clamping block 25 is extended, the positioning rod 19 is plugged into the positioning hole 11, so that the clamping block 25 is clamped and locked with the first limiting clamping groove 10, thereby avoiding accidental disconnection of the connecting member 2 and the dustproof mechanism 1 after the connection is completed. When the magnetic attraction plate 9 is electrically disconnected from the connecting line 3, the magnetic force of the magnetic attraction plate 9 disappears, and the second limiting clamping groove 22 is retracted into the inside of the clamping block 25 under the action of elastic force, and the magnetic attraction rod 26 is pressed to the initial position, so that the clamping block 25 and the first limiting clamping groove 10 are clamped and detached, thereby facilitating the release of the clamping state between the connecting member 2 and the dustproof mechanism 1.

[0056] Working principle: by pre-inserting the connector 5 into the device to be connected, and pre-connecting the connecting wire 3 to the power supply, when connection is needed, only the connector 2 and the dustproof mechanism 1 need to be brought close to each other to connect the connecting wire 3 and the connector 5. The operation is simple and convenient, and it can effectively prevent the connector 5 from being damaged due to multiple plugging and unplugging. At the same time, the connector 5 is connected to the dustproof mechanism 1, and the dustproof mechanism 1 can block the plug-in gap between the connector 5 and the connected device to prevent dust from entering the interface through the gap and affecting the stability of the connection. By electrically connecting the electromagnetic sheet 18 to the connecting wire 3, the electromagnetic sheet 18 can be magnetic when there is current in the connecting wire 3, so that the magnetic sheet 18 can attract the magnetic plate 9 through the magnetic attraction of the magnetic sheet 18, so that the magnetic attraction component 4 can be connected. When the connector 2 and the dustproof mechanism 1 are close to each other, the positioning rod 19 is inserted into the positioning hole 11 through the suction force between the electromagnetic sheet 18 and the magnetic suction plate 9, so that the connector 2 and the dustproof mechanism 1 are actively close to and attracted to each other, and the insertion of the positioning rod 19 can effectively avoid the situation in which the connector 2 and the dustproof mechanism 1 have a gap between the suction surfaces due to the tilt of the connector 2 during the magnetic attraction process, thereby affecting the connection quality. In order to facilitate the separation of the dustproof mechanism 1 and the connector 2, a contact electrode 14 is provided on the side end face of the connector 2. Since the dustproof mechanism 1 is relatively thin, the connector 2 needs to be held when the device is disconnected. In order to avoid the connector 5 from being separated from the connection device due to excessive suction of the magnetic suction component 4, a contact electrode 14 is provided. When the connector 2 is held When the contact electrode 14 receives the contact signal, the electromagnetic sheet 18 is disconnected from the connecting line 3, so that the magnetism of the electromagnetic sheet 18 disappears, and then the dustproof mechanism 1 and the connecting piece 2 can be easily separated, and it is the same as the user's usage habits. At the same time, the contact electrode 14 can be provided with multiple groups of symmetrical settings, such as symmetrically provided with two groups, and can be triggered only when multiple groups of contact electrodes 14 receive the contact signal, thereby avoiding the disconnection caused by the accidental touch of the contact electrode 14. When the dustproof mechanism 1 and the connecting piece 2 are attracted, the dustproof guard plate 27 presses the anti-magnetic suction guard plate 16, so that the rubber ring 15 is compressed, and then the elastic contact 21 is extended out of the surface of the plug-in slot 17, and the elastic contact 21 is inserted into the inside of the plug-in ring slot 8 to fit with the annular pole piece 12, so that the connecting piece 2 and the dustproof mechanism 1 is electrically connected, so that the connecting wire 3 is electrically connected to the plug connector 5, so that the electrical connection between the plug connector 5 and the connecting wire 3 is realized through the magnetic attraction component 4, and the dustproof guard plate 27 is rotatably connected to the dustproof mechanism 1, and the annular pole piece 12 is arranged in an annular shape, so that even if the connecting member 2 rotates when the connecting member 2 is in use, the elastic contact 21 and the annular pole piece 12 can maintain a stable electrical connection state, thereby effectively avoiding the situation where the cable connection of the traditional connection device is damaged or the connection is unstable due to the rotation of the connecting wire 3. When the plug-in ring groove 8 is not in use, the protective airbag 20 is used to seal the internal space of the plug-in ring groove 8, thereby effectively preventing dust and other impurities from entering the plug-in ring groove 8 and affecting the connection effect between the elastic contact 21 and the annular pole piece 12.When the elastic contact 21 is inserted into the plug-in ring groove 8, the protective airbag 20 is pressed to separate toward both sides and wrap the elastic contact 21, which can also prevent dust from entering the plug-in ring groove 8, and the annular pole pieces 12 are separated by the partition plate 13 to prevent liquid from entering the plug-in ring groove 8 and causing a short circuit between the annular pole pieces 12. When the magnetic plate 9 at the end of the positioning rod 19 is electrically connected to the connecting line 3, the magnetic rod 26 slides inside the sliding groove 23 under the action of magnetic traction, and the card block 25 can be extended inside the second limit card groove 22 under the action of the conical surface 24. After the card block 25 is extended, the positioning rod 19 is inserted into the positioning hole 11, so that the card block 25 is locked with the first limit card slot 10, thereby preventing the connector 2 from accidentally disconnecting with the dustproof mechanism 1 after the connection is completed. When the magnetic plate 9 is electrically disconnected from the connecting line 3, the magnetic force of the magnetic plate 9 disappears, and the second limit card slot 22 is retracted into the card block 25 under the action of elastic force, and the magnetic rod 26 is pressed to the initial position, so that the card block 25 and the first limit card slot 10 are locked and detached, thereby facilitating the release of the locking state between the connector 2 and the dustproof mechanism 1.
