[0038] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0039] like Figures 1 to 14 As shown, an embodiment of the present application provides a contactor, which includes: a housing 10; a contact structure 20, including a contact assembly 21, a first electromagnetic assembly 22 and a drive shaft 23 extending along a first direction X, the contact assembly 21 includes a static contact assembly 211 and a moving contact 212 arranged in sequence along the first direction X, the static contact assembly 211 is spaced apart from the drive shaft 23, the static contact assembly 211 includes a first static contact 213 and a second static contact 214 arranged at intervals along the circumference of the drive shaft 23, the moving contact 212 and the first electromagnetic assembly 22 are connected to the drive shaft 23 in sequence, and the first electromagnetic assembly 22 can drive the drive shaft 23 to move along the first direction X; a rotating structure 30, which is separated from the contact structure 20 and is arranged in the housing 10, including a second electromagnetic assembly 31 connected to the drive shaft 23, and the second electromagnetic assembly 31 can drive the drive shaft 23 to rotate.

[0040] In a specific implementation, the contactor of the embodiment of the present application includes a housing 10, a contact structure 20 and a rotating structure 30. The contact structure 20 and the rotating structure 30 are separated and arranged in the housing 10. The contact structure 20 includes a contact assembly 21, a first electromagnetic assembly 22 and a drive shaft 23. The static contact assembly 211 of the contact assembly 21 includes a first static contact 213 and a second static contact 214 spaced apart in the circumferential direction. The first static contact 213 and the second static contact 214 can be connected to different circuits outside the contactor respectively. The moving contact 212 is connected to the first electromagnetic assembly 22 through the drive shaft 23. The components 22 are connected, the first electromagnetic component 22 can drive the driving shaft 23 to move along the first direction X, thereby driving the moving contact 212 to contact or disconnect with the first static contact 213 or the second static contact 214, and the second electromagnetic component 31 of the rotating structure 30 can drive the driving shaft 23 to rotate, thereby driving the moving contact 212 to rotate circumferentially, so that the moving contact 212 rotates to the position of the first static contact 213 or the second static contact 214 respectively. Therefore, the contactor of the present application can be used in multi-line switching working scenarios to realize switching between different circuits.

[0041] Specifically, Figure 1 As shown, the moving contact 212 is a moving contact bridge structure, one end of the driving shaft 23 is fixed to the middle of the moving contact 212, and the two ends of the moving contact 212 are two moving contacts. The first static contact 213 and the second static contact 214 each include two static contact connection structures, which extend along the first direction X, one end of which is arranged inside the housing 10, and the other end of which passes through the housing 10 for connection with an external load. The two static contact connection structures of each static contact are arranged at intervals and can be opposite to the two moving contact points of the moving contact 212, so that when the moving contact 212 moves along the first direction X, the two moving contacts can contact the two static contact connection structures to achieve circuit connection. The cooperation between the moving contact bridge structure and the two static contact connection structures makes the contact structure 20 more stable when connecting the circuit, and avoids the situation where the moving contact 212 and the static contact assembly 211 have poor contact when connected.

[0042] Along the circumference of the drive shaft 23, the two static contact connecting structures of the first static contact 213 and the two static contact connecting structures of the second static contact 214 are arranged in sequence and spaced apart, and the connecting line between the two static contact connecting structures of the first static contact 213 is perpendicular to the connecting line between the two static contact connecting structures of the second static contact 214, so that when the moving contact 212 is rotated 90°, it can be switched to connect with different static contacts.

[0043] Optionally, the static contact assembly 211 may include more than two static contacts, and the multiple static contacts may be arranged in sequence and spaced apart along the circumference of the drive shaft 23. Such an arrangement enables the moving contact 212 to be connected to the multiple static contacts respectively, thereby connecting multiple external circuits and realizing switching of more circuits.

[0044] like Figure 7 As shown, the contactor of the embodiment of the present application has two positioning structures 11 arranged at intervals along the circumference of the driving shaft 23 in the shell 10, and the two positioning structures 11 are arranged opposite to the first static contact 213 and the second static contact 214 in the circumferential direction of the driving shaft 23; the rotating structure 30 includes a positioning portion 32 connected to the driving shaft 23, the positioning portion 32 and the two positioning structures 11 are in the same plane, and the positioning portion 32 is rotatably arranged between the two positioning structures 11.

[0045] In a specific implementation, the positioning portion 32 is connected to the drive shaft 23. When the drive shaft 23 rotates, the positioning portion 32 rotates between the two positioning structures 11 at the same time. Since the two positioning structures 11 are respectively arranged relative to the first static contact 213 and the second static contact 214, when the positioning portion 32 rotates to the positions of the two positioning structures 11, the moving contact 212 can be positioned at the positions of the first static contact 213 and the second static contact 214, so that the moving contact 212 is precisely in contact with the first static contact 213 or the second static contact 214, thereby ensuring the connectivity of the circuit.

[0046] like Figure 1 and Figure 6 As shown, the contactor of the embodiment of the present application, wherein the first electromagnetic component 22 includes a first coil structure 221, a moving iron core 222, and a fixed magnetic yoke 223 and a guide sleeve 224 arranged at intervals along the first direction X, the first coil structure 221 surrounds the drive shaft 23 and is arranged at intervals from the outer circumferential surface of the drive shaft 23, the moving iron core 222 is arranged between the first coil structure 221 and the drive shaft 23, and the moving iron core 222 is fixedly connected to the outer circumferential surface of the drive shaft 23, the fixed magnetic yoke 223 and the guide sleeve 224 are respectively in contact with different parts of the shell 10, the guide sleeve 224 has a sliding space arranged through the first direction X, the moving iron core 222 is slidably arranged in the sliding space, and the moving iron core 222 can slide along the first direction X until it contacts the fixed magnetic yoke 223.

[0047] In specific implementation, the first coil structure 221 is arranged to surround the drive shaft 23 and be spaced apart from the outer peripheral surface of the drive shaft 23. After the first coil structure 221 is energized, a magnetic field along the first direction X will be generated in the space surrounded by it. The direction of the magnetic field is determined according to the direction of the current in the first coil structure 221. The moving iron core 222 is arranged between the first coil structure 221 and the drive shaft 23. Under the action of the magnetic field force of the first coil structure 221, it will move along the first direction X, thereby driving the drive shaft 23 and the moving contact 212 connected to the drive shaft 23 to move along the first direction X, thereby realizing the connection and disconnection between the moving contact 212 and the static contact assembly 211.

[0048] The guide sleeve 224 extends along the first direction X and is sleeved on the outer peripheral surface of the moving iron core 222. When the moving iron core 222 is subjected to the magnetic field force of the first coil structure 221, the moving iron core 222 can slide along the inner surface of the guide sleeve 224, thereby ensuring the moving direction of the moving iron core 222 and preventing the moving iron core 222 from deviating from the first direction X during movement, causing the contact assembly 21 to fail to be normally connected.

[0049] The fixed magnetic yoke 223 and the guide sleeve 224 are in contact with different parts of the housing 10 respectively, so the fixed magnetic yoke 223, the guide sleeve 224 and the housing 10 together enclose the first coil structure 221. Figure 6 As shown, after the first coil structure 221 is energized, the fixed magnetic yoke 223, the shell 10, the guide sleeve 224 and a small amount of air together form a closed magnetic circuit, and the moving iron core 222 can move up and down along the first direction X under the action of the closed magnetic circuit. In addition, the setting of the fixed magnetic yoke 223 can strengthen the magnetic field, so that the first coil structure 221 can more easily drive the moving iron core 222 to move.

[0050] Specifically, the first electromagnetic component 22 also includes a skeleton structure 227, which together with the shell 10 encloses the first coil structure 221. The setting of the skeleton structure 227 enables the first coil structure 221 to have a support base, so that it can be fixed on the inner surface of the shell 10 and set around the moving iron core 222; the skeleton structure 227 also includes a protruding support structure 228, which protrudes toward the drive shaft 23, and in the first direction X, there is a spacing distance between the support structure 228 and the fixed magnetic yoke 223. Similarly, the outer peripheral surface of the moving iron core 222 also has a protruding structure matching the support structure 228. When the moving iron core 222 is subjected to the magnetic field force and moves along the first direction X, the protruding structure of the moving iron core 222 can only move within the spacing distance between the support structure 228 and the fixed magnetic yoke 223. The support structure 228 limits the protruding structure and prevents the moving iron core 222 from continuing to move downward.

[0051] like Figure 1As shown, the contactor of the embodiment of the present application, wherein the moving contact 212 is slidably connected to the drive shaft 23 along the first direction X, the contact structure 20 further includes an elastic component 24, the elastic component 24 includes a first elastic member 241 and a second elastic member 242, the first elastic member 241 and the second elastic member 242 are both retractably arranged along the first direction X, one end of the first elastic member 241 is fixed to the moving contact 212, and the other end is fixed to the surface of the drive shaft 23 below the moving contact 212, one end of the second elastic member 242 is connected to the fixed yoke 223, and the other end is connected to the moving iron Core 222; the moving iron core 222 includes a first accommodating cavity 225 and a second accommodating cavity 226 that are connected to each other. The first accommodating cavity 225 and the second accommodating cavity 226 penetrate the moving iron core 222 along the first direction X. The diameter of the first accommodating cavity 225 is smaller than the diameter of the second accommodating cavity 226, and the second accommodating cavity 226 is arranged close to the moving contact 212. The driving shaft 23 is penetrated by the first accommodating cavity 225 and the second accommodating cavity 226 and is connected to the inner surface of the second accommodating cavity 226. The second elastic member 242 is sleeved on the outer peripheral surface of the driving shaft 23 and is arranged in the first accommodating cavity 225.

[0052] During specific implementation, when the moving contact 212 contacts the static contact assembly 211, the static contact assembly 211 applies a downward force along the first direction X to the moving contact 212. Since the bottom of the moving contact 212 is connected to the first elastic member 241, the first elastic member 241 is compressed by the force of the static contact assembly 211, thereby generating an upward elastic force along the first direction X on the moving contact 212, so that the moving contact 212 can always maintain contact with the static contact assembly 211, thereby ensuring the connectivity of the contact assembly 21.

[0053] One end of the second elastic member 242 is connected to the fixed magnetic yoke 223, and the other end is connected to the moving iron core 222. When the moving iron core 222 moves upward due to the magnetic field force, the second elastic member 242 will be compressed. When the power is removed from the first coil structure 221, the moving iron core 222 will not be driven by the magnetic field force. The second elastic member 242 can then return to its natural state and drive the moving iron core 222 to move downward, thereby disconnecting the contact assembly 21. The second elastic member 242 is provided so that the moving iron core 222 does not need to be driven by the magnetic field force when moving downward, so that the first coil structure 221 does not need to be powered, which has an energy-saving effect.

[0054] A first accommodating cavity 225 and a second accommodating cavity 226 are provided in communication inside the moving iron core 222, so that the driving shaft 23 can pass through the first accommodating cavity 225 and the second accommodating cavity 226 respectively, and be connected to the rotating structure 30, so that the driving shaft 23 realizes the overall drive for rotation and up and down movement along the first direction X; the second elastic member 242 is sleeved on the outer circumferential surface of the driving shaft 23 and is arranged in the first accommodating cavity 225. Since the diameter of the first accommodating cavity 225 is smaller than the diameter of the second accommodating cavity 226, the bottom of the second elastic member 242 can be fixed on the step surface formed between the first accommodating cavity 225 and the second accommodating cavity 226, so that the second elastic member 242 can be fixed in the first direction X, and when the moving iron core 222 moves, the second elastic member 242 can be compressed.

[0055] like Figure 3 and Figure 4 As shown, the contactor of the embodiment of the present application, wherein the second electromagnetic component 31 includes a second coil structure 311 and a rotor 312, the rotor 312 is made of magnetic material, the rotor 312 is sleeved on the drive shaft 23 and fixedly connected to the drive shaft 23, the second coil structure 311 is distributed along the circumference of the rotor 312, and the second coil structure 311 is used to drive the rotor 312 to rotate.

[0056] In specific implementation, the second coil structure 311 is distributed along the circumference of the rotor 312, that is, it surrounds the rotor 312, and the rotor 312 is sleeved on the outer circumferential surface of the drive shaft 23 and fixedly connected to the drive shaft 23. After power is applied to the second coil structure 311, the magnetic field generated by it can generate a magnetic field force on the rotor 312 of the magnetic material. Under the driving action of the magnetic field force, the rotor 312 drives the drive shaft 23 to rotate together, so that the drive shaft 23 can drive the moving contact 212 to rotate, so as to realize the connection between the moving contact 212 and different static contacts, thereby completing the switching of the circuit.

[0057] like Figure 3 and Figure 4 As shown, the contactor of the embodiment of the present application, wherein the second coil structure 311 includes a first auxiliary coil 313 and a second auxiliary coil 314 with opposite current directions, the first auxiliary coil 313 and the second auxiliary coil 314 are symmetrically arranged on both sides of the rotor 312 along the rotation center of the rotor 312, the rotor 312 includes a first magnetic pole 315 and a second magnetic pole 316 with opposite polarities, the first magnetic pole 315 is arranged close to the first auxiliary coil 313, and the second magnetic pole 316 is arranged close to the second auxiliary coil 314, the first magnetic pole 315 and the second magnetic pole 316 are semicircular ring structures of the same shape, and at the limiting position of the two positioning structures 11, the boundary line of the first magnetic pole 315 and the second magnetic pole 316 is arranged to intersect with the direction from the first auxiliary coil 313 to the second auxiliary coil 314.

[0058] In a specific implementation, the first auxiliary coil 313 and the second auxiliary coil 314 are symmetrically arranged on both sides of the rotor 312 along the rotation center of the rotor 312, and the polarities of the first magnetic pole 315 and the second magnetic pole 316 are opposite. Therefore, the currents in the first auxiliary coil 313 and the second auxiliary coil 314 are opposite in direction, and the polarities of the first auxiliary coil 313 and the first magnetic pole 315 are the same, and the polarities of the second auxiliary coil 314 and the second magnetic pole 316 are the same. In this way, the first auxiliary coil 313 can generate a repulsive magnetic field force with the first magnetic pole 315, and the second auxiliary coil 314 can generate a repulsive magnetic field force with the second magnetic pole 316, so that the rotor 312 can rotate as a whole.

[0059] Moreover, since the boundary line between the first magnetic pole 315 and the second magnetic pole 316 is arranged to intersect with the direction from the first auxiliary coil 313 to the second auxiliary coil 314, the two auxiliary coils respectively generate repulsive forces on the two magnetic poles along the circumference of the rotor 312, and the directions of the repulsive forces are all clockwise, generating a combined force that enables the rotor 312 to rotate, thereby avoiding the repulsive force on the first magnetic pole 315 and the repulsive force on the second magnetic pole 316 to cancel each other out in the opposite horizontal direction, thereby avoiding the situation where the rotor 312 cannot rotate.

[0060] like Figure 3 and Figure 4 As shown, the contactor of the embodiment of the present application, wherein the second electromagnetic component 31 also includes an auxiliary magnetic conductive structure 317, a first stator 318 and a second stator 319, the auxiliary magnetic conductive structure 317 is an annular structure arranged on the outer peripheral side of the rotor 312, the first stator 318 and the second stator 319 are arranged to protrude from the inner surface of the auxiliary magnetic conductive structure 317, the first auxiliary coil 313 is installed on the first stator 318, and the second auxiliary coil 314 is installed on the second stator 319.

[0061] In specific implementation, the auxiliary magnetic conductive structure 317 is an annular structure, which is arranged on the outer peripheral side of the rotor 312. The first stator 318 and the second stator 319 are arranged to protrude from the inner surface of the auxiliary magnetic conductive structure 317, and the first auxiliary coil 313 is installed on the first stator 318, and the second auxiliary coil 314 is installed on the second stator 319. The magnetic field will extend along the overall shape formed by the auxiliary magnetic conductive structure 317, the first stator 318 and the second stator 319, so as to achieve the effect of magnetic conductivity, so that a complete magnetic field is formed in the second electromagnetic component 31, and the rotation and positioning of the rotor 312 can be better realized in the overall magnetic field.

[0062] Under the action of the magnetic field of the second coil structure 311, the rotor 312 has three different states:

[0063] Figure 8The figure shows the first state. In the first state, the second coil structure 311 is not energized, the rotor 312 does not rotate, and the positioning portion 32 connected to the rotor 312 is located at the position of the first positioning structure 11, that is, the limit position of the positioning structure 11 close to the second stator 319 on the right side in the figure. At this time, the magnetic field is only provided by the rotor 312 of the magnetic material, so the direction of the magnetic field is the first magnetic pole 315, the first stator 318, the auxiliary magnetic conductive structure 317, the second stator 319 to the second magnetic pole 316. In this complete magnetic circuit, the rotor 312 will be subjected to a weaker magnetic force in the counterclockwise direction, so that it can be maintained at the limit position of the right positioning structure 11. In this position, the moving contact 212 is opposite to the first static contact 213.

[0064] Fig. 9 The figure shows the second state. In the second state, the second coil structure 311 is energized, the magnetic field generated by the first auxiliary coil 313 has the same polarity as the first magnetic pole 315, the magnetic field generated by the second auxiliary coil 314 has the same polarity as the second magnetic pole 316, and the direction of the magnetic field is affected by the first auxiliary coil 313 and the second auxiliary coil 314. The overall magnetic field direction is from the second stator 319 and the auxiliary magnetic conductive structure 317 to the first stator 318, so that the first stator 318 has the same polarity as the first magnetic pole 315, and the second stator 319 has the same polarity as the second magnetic pole 316. The two stators can respectively generate clockwise repulsive forces on the two magnetic poles, causing the rotor 312 to move clockwise until the positioning portion 32 abuts against the second positioning structure 11, completing the rotation process of the drive shaft 23.

[0065] Fig.10 The third state is shown. In the third state, the power is canceled in the second coil structure 311, the rotor 312 stops rotating, and the positioning portion 32 connected to the rotor 312 is located at the position of the second positioning structure 11, that is, the limit position of the positioning structure 11 close to the first stator 318 on the left side in the figure, and the first magnetic pole 315 is close to the second stator 319, and the second magnetic pole 316 is close to the first stator 318. At this time, only the rotor 312 of magnetic material provides a magnetic field, and the direction of the magnetic field is the second magnetic pole 316, the second stator 319, the auxiliary magnetic conductive structure 317, the first stator 318 to the first magnetic pole 315. In this complete magnetic circuit, the rotor 312 will be subjected to a weaker magnetic force in the clockwise direction, so that it can be maintained at the limit position of the left positioning structure 11. In this position, the moving contact 212 and the second static contact 214 are opposite to each other.

[0066] Specifically, the first stator 318 and the second stator 319 each include a connecting portion and a magnetic conductive portion. The connecting portion is a rod-shaped structure, one end of which is connected to the auxiliary magnetic conductive structure 317, and the other end is connected to the magnetic conductive portion. The magnetic conductive portion is an arc-shaped structure, which can surround a portion of the outer circumference of the first magnetic pole 315 or the second magnetic pole 316. Such a setting can expand the corresponding area between the stator and the magnetic pole. When the stator is magnetic, the interaction force between the stator and the corresponding magnetic pole is large, which can drive the rotor 312 to rotate.

[0067] like Figure 5 As shown, a contactor of an embodiment of the present application, wherein a partition 12 is further provided inside the shell 10, the partition 12 has a connecting hole 121 penetrating along the first direction X, the shell 10 includes a first installation space 13 and a second installation space 14 sequentially arranged along the first direction X, the first installation space 13 and the second installation space 14 are respectively arranged on both sides of the partition 12, at least a portion of the contact structure 20 is arranged in the first installation space 13, at least a portion of the rotating structure 30 is arranged in the second installation space 14, the drive shaft 23 is rotatably arranged in the connecting hole 121, and two positioning structures 11 are connected to the side of the partition 12 facing the second installation space 14 at intervals along the circumference of the connecting hole 121, and along the circumference of the connecting hole 121, the angle between the two positioning structures 11 is 90°.

[0068] In a specific implementation, the partition 12 can separate the space inside the shell 10 into a first installation space 13 and a second installation space 14, thereby separating the contact structure 20 and the rotating structure 30, avoiding the mutual influence between the magnetic field generated by the first electromagnetic component 22 of the contact structure 20 and the magnetic field generated by the second electromagnetic component 31 of the rotating structure 30, causing the contact component 21 to be unable to connect normally.

[0069] The angle between the two positioning structures 11 is set to 90°, so that the positioning part 32 can only rotate within a range of 90°. This setting matches the setting method of the first static contact 213 and the second static contact 214. When the positioning part 32 abuts against the two positioning structures 11, the moving contact 212 can reach the positions opposite to the first static contact 213 and the second static contact 214 respectively, thereby completing the connection of the circuit.

[0070] like Figure 1 and Figure 4As shown, the contactor of an embodiment of the present application, wherein the drive shaft 23 includes a drive shaft body 231 and a connecting sleeve 232, the drive shaft body 231 has a fixing pin 233 protruding radially, the drive shaft body 231 is detachably connected to the connecting sleeve 232 via the fixing pin 233, the connecting sleeve 232 is arranged in the second installation space 14 and is connected to the second electromagnetic assembly 31, the drive shaft body 231 is passed through the connecting hole 121 and is connected to the contact assembly 21 and the first electromagnetic assembly 22.

[0071] During specific implementation, the drive shaft body 231 passes through the connecting hole 121, one end of which is arranged in the first installation space 13, and the other end of which is arranged in the second installation space 14, and the connecting sleeve 232 is arranged in the second installation space 14 and connected to the second electromagnetic component 31. Through the cooperation between the connecting sleeve 232 and the drive shaft body 231, the drive shaft 23 can be installed and cooperated with the contact structure 20 and the rotating structure 30 in the first installation space 13 and the second installation space 14 respectively, and the detachable setting of the connecting sleeve 232 and the drive shaft body 231 facilitates the installation and disassembly of the drive shaft 23 as a whole in the shell 10.

[0072] like Figures 11 to 14 As shown, the contactor of the embodiment of the present application, wherein the contactor also includes: an upper end cover 40, the upper end cover 40 is covered on the top of the shell 10 along the first direction X, the upper end cover 40 has two isolation plates 41 protruding along the first direction X, the two isolation plates 41 are intersected and formed to form a plurality of isolation areas 42, and the plurality of isolation areas 42 are arranged opposite to the two ends of the first static contact 213 and the two ends of the second static contact 214; a lower end cover 50, the lower end cover 50 is covered on the bottom of the shell 10 along the first direction X, a bearing groove 51 is arranged at the center of the lower end cover 50, the bearing groove 51 is used to install a bearing 52, and the end of the drive shaft 23 is rotatably installed in the bearing groove 51 through the bearing 52.

[0073] In a specific implementation, the two isolation plates 41 of the upper end cover 40 are arranged to intersect and form a plurality of isolation areas. The first static contact 213 and the second static contact 214 are separated by the isolation plate 41, and the plurality of isolation areas 42 are arranged relative to the two ends of the first static contact 213 and the two ends of the second static contact 214. When the moving contact 212 is separated from the two ends of the first static contact 213 or the two ends of the second static contact 214, an arc is generated. The isolation plate 41 can separate the arcs in different isolation areas 42 to avoid phase breakdown.

[0074] The bearing groove 51 is opened at the center of the lower end cover 50 for installing the bearing 52. When the drive shaft 23 is installed inside the housing 10, its end can be stably installed in the bearing groove 51 through the bearing 52 and can rotate stably to avoid the moving contact 212 being unable to align with the first static contact 213 or the second static contact 214, resulting in the circuit being unable to connect.

[0075] Specifically, the lower end cover 50 further includes two installation grooves 53 arranged at intervals for installing the first auxiliary coil 313 and the second auxiliary coil 314 to avoid positional conflict between the first auxiliary coil 313 and the second auxiliary coil 314 and the lower end cover 50 during installation.

[0076] Specifically, the upper end cover 40 and the lower end cover 50 each include a plurality of screw holes for inserting screws or bolt structures, so as to fix the upper end cover 40 and the lower end cover 50 to the housing 10 to achieve the overall packaging of the contactor.
