Description

[0002] In industrial equipment, contactors are an indispensable part of the entire circuit. Contactors usually use the method of controlling coil current to generate a magnetic field, which drives the electromagnetic mechanism to move, and the movement of the electromagnetic mechanism drives the contact to close, thereby controlling the on and off of the entire circuit.

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figures 1 to 4 As shown, an embodiment of the present application provides a contactor, which includes: a shell 10, including a shell body 11 and an arc-extinguishing sleeve 12 arranged inside the shell body 11, and an inert gas or hydrogen is arranged inside the arc-extinguishing sleeve 12; a contact structure 20, at least partially arranged inside the arc-extinguishing sleeve 12, including a contact assembly 21, the contact assembly 21 includes a coaxially arranged static contact assembly 211 and a moving contact 212, the moving contact 212 is movably arranged in the arc-extinguishing sleeve 12, and the static contact assembly 211 includes a first static contact 213 and a second static contact 214 arranged along its own circumferential interval; a rotating structure 30, at least partially arranged inside the arc-extinguishing sleeve 12, the rotating structure 30 is drivingly connected to the moving contact 212, and is used to drive the moving contact 212 to rotate to the position of the first static contact 213 or the second static contact 214.

[0025] In 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 at least partially arranged inside a closed arc-extinguishing sleeve 12. The contact structure 20 includes a coaxially arranged static contact assembly 211 and a moving contact 212. The static contact assembly 211 includes a first static contact 213 and a second static contact 214 arranged at intervals along its own circumference. The rotating structure 30 can drive the moving contact 212 to rotate to the position of the first static contact 213 or the second static contact 214 to realize the contactor line switching. Function: Since the moving contact 212 is movably arranged in the arc extinguishing sleeve 12, an arc will be generated in the arc extinguishing sleeve 12 when it contacts or separates from the first static contact 213 and the second static contact 214. The inert gas or hydrogen arranged inside the arc extinguishing sleeve 12 is beneficial to the rapid cooling and extinguishing of the arc, which can ensure the arc extinguishing effect on the contact assembly 21, and the arc extinguishing sleeve 12 accommodates the rotatable moving contact 212 and the rotating structure 30 that drives the moving contact 212 to rotate, which will not interfere with the rotation of the moving contact 212, thereby ensuring the breaking performance of the contactor.

[0026] Specifically, the moving contact 212 is a moving contact bridge structure, with two moving contacts at both ends, and the first static contact 213 and the second static contact 214 each include two static contact connection structures, the static contact connection structure extends along the first direction X, one end is arranged inside the arc extinguishing sleeve 12, and the other end passes through the arc extinguishing sleeve 12, and is used to connect with an external load, and the two static contact connection structures of each static contact are arranged at intervals, and can be opposite to the two moving contacts 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 poor contact between the moving contact 212 and the static contact assembly 211 when connected.

[0027] 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.

[0028] 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.

[0029] like Figure 1 and Figure 2 As shown, the contactor of the embodiment of the present application, wherein the contact structure 20 also includes a driving shaft 23 extending along the first direction X, the driving shaft 23 is respectively connected to the moving contact 212 and the rotating structure 30, and a positioning portion 231 is arranged on the outer circumferential surface of the driving shaft 23; a limiting structure 121 is arranged inside the arc extinguishing sleeve 12, the limiting structure 121 includes two limiting portions 122 arranged at intervals along the circumferential direction of the arc extinguishing sleeve 12, the two limiting portions 122 are respectively arranged opposite to the first static contact 213 and the second static contact 214, the positioning portion 231 is arranged opposite to the limiting structure 121, and the positioning portion 231 is rotatably arranged between the two limiting portions 122.

[0030] In a specific implementation, the drive shaft 23 is extended along the first direction X, and is respectively connected to the moving contact 212 and the rotating structure 30. The rotating structure 30 can drive the drive shaft 23 to rotate, so that the drive shaft 23 drives the moving contact 212 to rotate, so that the moving contact 212 can reach the position of the first static contact 213 or the second static contact 214, respectively, and can contact the first static contact 213 or the second static contact 214, respectively; a positioning portion 231 is provided on the outer circumferential surface of the drive shaft 23, and a limiting structure 121 having two limiting portions 122 is provided inside the arc extinguishing sleeve 12. When the positioning portion 231 rotates to a certain position in the limiting structure 121, it will contact the limiting portion 122. The limiting portion 122 will restrict the positioning portion 231 from continuing to rotate, thereby stopping the rotation of the drive shaft 23 and the moving contact 212 connected to the drive shaft 23, so that the moving contact 212 can be fixed in a position in contact with the first static contact 213 or the second static contact 214, thereby preventing the moving contact 212 from rotating when connected to the first static contact 213 or the second static contact 214, resulting in a circuit disconnection, thereby ensuring the connection stability of the contactor.

[0031] like Figure 3 As shown, the contactor of the embodiment of the present application, wherein the limiting structure 121 is a recessed structure arranged in the side wall of the arc-extinguishing sleeve 12, the limiting structure 121 is arranged along the radial recess away from the driving shaft 23, and the limiting structure 121 extends along the circumference of the arc-extinguishing sleeve 12, and the angle covered by the limiting structure 121 along the circumference of the arc-extinguishing sleeve 12 is 90°.

[0032] During specific implementation, the limiting structure 121 is arranged on the side wall of the arc extinguishing sleeve 12 along a radial recess away from the driving shaft 23. In this way, when designing the arc extinguishing sleeve 12, there is no need to reserve space for the limiting structure 121, and there is no need to design a larger diameter for the arc extinguishing sleeve 12, thereby reducing the overall volume of the arc extinguishing sleeve 12; the limiting structure 121 extends along the circumference of the arc extinguishing sleeve 12, and the angle covered by the limiting structure 121 along the circumference of the arc extinguishing sleeve 12 is 90°, so that the positioning portion 231 can only rotate 90° in the limiting structure 121, so that the moving contact 212 can only rotate 90°, that is, switch between the first static contact 213 and the second static contact 214, to avoid the phenomenon of overtravel of the moving contact 212.

[0033] like Figure 1 and Figure 4 As shown, a contactor of an embodiment of the present application, wherein the arc-extinguishing sleeve 12 includes a first cylinder 123 and a second cylinder 124 connected along a first direction X, the contact assembly 21 is disposed in the first cylinder 123, at least a portion of the rotating structure 30 is disposed in the second cylinder 124, the diameter of the first cylinder 123 is greater than the diameter of the second cylinder 124, and the limiting structure 121 is disposed at the connection between the first cylinder 123 and the second cylinder 124.

[0034] During specific implementation, the first cylinder 123 and the second cylinder 124 of the arc extinguishing sleeve 12 are respectively used to install the contact assembly 21 and the rotating structure 30, so that the contact assembly 21 and the rotating structure 30 have independent installation space and will not interfere with each other; and the diameter of the first cylinder 123 is larger than the diameter of the second cylinder 124, and the limiting structure 121 is arranged at the connection between the first cylinder 123 and the second cylinder 124, so that the diameter of the arc extinguishing sleeve 12 gradually decreases along the direction from the second cylinder 124, the limiting structure 121 to the first cylinder 123, and the outer shell body 11 can also be set to a shell structure that is compatible with the shape of the arc extinguishing sleeve 12. In the process of installing the arc extinguishing sleeve 12, the second cylinder 124 with a smaller diameter of the arc extinguishing sleeve 12 can be installed first, and then the limiting structure 121 and the first cylinder 123 can be installed in the outer shell body 11 in turn. Such a structural setting facilitates the installation of the arc extinguishing sleeve 12.

[0035] like Figure 1 As shown, in the contactor of the embodiment of the present application, the first cylinder 123 includes a cylinder portion 125 and a sealing cover 126, the two ends of the cylinder portion 125 respectively have a first opening and a second opening, the first cylinder 123 is connected to the second cylinder 124 through the second opening, the sealing cover 126 is covered on the first opening, and the sealing cover 126 and the cylinder portion 125 are sealed and connected by a sealant.

[0036] During specific implementation, a sealing cover 126 is provided at the first opening of the first cylinder 123, and the sealing cover 126 is sealed to the cylinder portion 125 by means of a sealant. The setting of the sealing cover 126 enables the gas in the first cylinder 123 and the gas in the second cylinder 124 to be sealed inside without leakage, which would affect the overall arc extinguishing effect of the contactor.

[0037] Specifically, the first cylinder 123, the limiting structure 121 and the second cylinder 124 are in a fully connected state. The first cylinder 123 has an inner cylinder structure 127 inside. The inner cylinder structure 127 includes an inner cylinder side wall 128 that fits with the side wall portion of the cylinder portion 125 of the first cylinder 123, and also includes a retaining structure 129 connected to the end of the inner cylinder side wall 128. The retaining structure 129 is arranged at the second opening. A connecting hole is opened in the center of the retaining structure 129 for passing the drive shaft 23. The setting of the retaining structure 129 can separate the contact structure 20 and the rotating structure 30 to avoid the influence between the two. The retaining structure 129 can also provide an installation basis for the contact structure 20, so that the contact structure 20 can be stably installed in the first cylinder 123.

[0038] like Figure 1 As shown, the contactor of an embodiment of the present application, wherein the rotating structure 30 includes a second electromagnetic component 31, the second electromagnetic component 31 includes a second coil structure 311 and a rotor 312, the rotor 312 is made of magnetic material, and is arranged between the drive shaft 23 and the arc extinguishing sleeve 12, the rotor 312 is fixedly connected to the drive shaft 23, and the second coil structure 311 is arranged between the arc extinguishing sleeve 12 and the shell body 11.

[0039] In a specific implementation, since the second coil structure 311 is arranged around the rotor 312 of magnetic material, when power is supplied to the inside of the second coil structure 311, a magnetic field can be generated to drive the rotor 312 to rotate. Under the action of the magnetic field force, the rotor 312 drives the drive shaft 23 fixedly connected thereto to rotate together, so that the drive shaft 23 can drive the moving contact 212 to rotate, thereby completing the switching of different circuits.

[0040] Moreover, the second coil structure 311 is arranged between the arc extinguishing sleeve 12 and the shell body 11, and the internal rotor 312 is driven outside the arc extinguishing sleeve 12. Such an arrangement can reduce the volume of the arc extinguishing sleeve 12. There is no need to reserve space inside the arc extinguishing sleeve 12 for the larger second coil structure 311, so that the diameter of the second cylinder 124 can be smaller than the first cylinder 123, thereby facilitating the installation of the arc extinguishing sleeve 12.

[0041] In the contactor of the embodiment of the present application, the arc-extinguishing sleeve 12 is made of brass material.

[0042] In a specific implementation, the arc extinguishing sleeve 12 is made of brass, which can prevent the arc extinguishing sleeve 12 from being magnetized when the second coil structure 311 is energized, thereby affecting the overall magnetic field and affecting the use of the contactor. In addition, the arc extinguishing sleeve 12 made of brass will not have an isolation effect on the magnetic field, and the second coil structure 311 disposed outside the arc extinguishing sleeve 12 can still drive the rotor 312, thereby deflecting the moving contact 212.

[0043] like Figure 1 As shown, the contactor of the embodiment of the present application, wherein the sealing cover 126 has a plurality of mounting holes, the first static contact 213 and the second static contact 214 are both penetrated through the sealing cover 126 through the mounting holes, the first static contact 213 and the second static contact 214 are both sealed and connected to their respective corresponding mounting holes, and the sealing connection setting can avoid gas leakage inside the arc extinguishing sleeve 12 to ensure the arc extinguishing effect of the contactor.

[0044] In a specific implementation, the first static contact 213 and the second static contact 214 need to pass through the sealing cover 126 through the mounting hole, so that the first ends of the first static contact 213 and the second static contact 214 are arranged inside the arc extinguishing sleeve 12 for contacting the moving contact 212, and the second ends are arranged outside to be connected to the external load, so that when the moving contact 212 contacts the first end of the first static contact 213 or the first end of the second static contact 214, the entire circuit can be connected.

[0045] like Figure 1 and Figure 2 As shown, the contactor of the embodiment of the present application, wherein the contact structure 20 also includes a first electromagnetic component 22, the first electromagnetic component 22 is arranged in the first cylinder 123, the moving contact 212 and the first electromagnetic component 22 are connected to the drive shaft 23 in sequence, and the first electromagnetic component 22 can drive the drive shaft 23 to move along the first direction X.

[0046] In specific implementation, the first electromagnetic assembly 22 generates a magnetic field after being energized, and the magnetic field force can drive the driving shaft 23 to move along the first direction X as a whole, thereby driving the moving contact 212 to move along the first direction X to achieve connection and disconnection with the static contact assembly 211.

[0047] like Figure 1 and Figure 2 As shown, the contactor of an embodiment of the present application, wherein the first electromagnetic component 22 includes a first coil structure 221 and a moving iron core 222, the first coil structure 221 surrounds the drive shaft 23 and is spaced apart from the outer circumference 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 circumference of the drive shaft 23.

[0048] In specific implementation, the first coil structure 221 surrounds the drive shaft 23 and is spaced apart from the outer circumference of the drive shaft 23. The moving iron core 222 is disposed between the first coil structure 221 and the drive shaft 23. After the first coil structure 221 is energized, a magnetic field is generated to drive the moving iron core 222 to move in the first direction X. Since the moving iron core 222 is fixedly connected to the outer circumference of the drive shaft 23, the moving iron core 222 drives the drive shaft 23 to move in the first direction X when moving, thereby driving the moving contact 212 to move in the first direction X, thereby achieving connection and disconnection with the static contact assembly 211.

[0049] Specifically, the first electromagnetic component 22 also includes a fixed yoke 223 and a guide sleeve 224 arranged at intervals along the first direction X. The fixed yoke 223 and the guide sleeve 224 are respectively in contact with different parts of the inner cylinder structure 127. Therefore, the fixed yoke 223, the guide sleeve 224 and the inner cylinder structure 127 jointly enclose the first coil structure 221. After the first coil structure 221 is energized, the fixed yoke 223, the inner cylinder structure 127, the guide sleeve 224 and a small part of the air jointly form a closed magnetic circuit. The moving iron core 222 can move along the first direction under the action of the closed magnetic circuit. X moves up and down, and the setting of the fixed 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; the guide sliding sleeve 224 has a sliding space set along the first direction X, and the moving iron core 222 can be slidably set in the sliding space. The moving iron core 222 can slide along the first direction X until it contacts with the fixed yoke 223. The setting of the guide sliding sleeve 224 ensures the moving direction of the moving iron core 222, thereby preventing the moving iron core 222 from deviating from the first direction X during the movement, resulting in the contact assembly 21 being unable to be normally connected.

[0050] Specifically, the moving contact 212 is slidably connected to the drive shaft 23 along the first direction X, and the contact structure 20 also includes an elastic component 24, which 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 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.

[0051] 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.

[0052] 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.

[0053] Specifically, the first electromagnetic component 22 also includes a skeleton structure 227, which together with the inner cylinder structure 127 encloses the first coil structure 221. The setting of the skeleton structure 227 enables the first coil structure 221 to have a support base, and can be fixed on the inner surface of the inner cylinder structure 127 and arranged 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.
