[0041] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0042] The contactor 100 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] like Figures 1 to 4 As shown, the contactor 100 according to an embodiment of the present invention includes a body 10, a conductive element 20, and a movable element 30.

[0044] Specifically, the main body 10 is provided with a mounting cavity, and a contact portion 11 is provided in the mounting cavity. A conductive element 20 is disposed in the mounting cavity. The conductive element 20 includes a first functional segment 21 and a second functional segment 22. The first functional segment 21 is movable between a first position and a second position. When the first functional segment 21 is in the first position, the first functional segment 21 is in contact with the contact portion 11. When the first functional segment 21 is in the second position, the first functional segment 21 is spaced apart from the contact portion 11. A movable element 30 is disposed in the mounting cavity. The movable element 30 is adapted to separate the first functional segment 21 and the second functional segment 22 under a set working condition so that the conductive element 20 is disconnected.

[0045] In other words, such as Figures 1 to 4As shown, the contactor 100 according to an embodiment of the present invention mainly includes a body 10, a conductive element 20, and a movable element 30. The body 10 has a sealed mounting cavity, within which a contact portion 11 adapted to the movable element 30 is provided. The contact portion 11 is used for electrical connection with an external circuit. The conductive element 20 is disposed within the mounting cavity and includes a first functional segment 21 and a second functional segment 22 connected to each other. Specifically, the first functional segment 21 is movable between a first position and a second position, allowing the first functional segment 21 to contact or be spaced from the contact portion 11, thereby enabling the contactor 100 to switch between an on state and an off state.

[0046] like Figure 1 and Figure 2 As shown, when the first functional segment 21 is in the first position, the first functional segment 21 contacts the contact portion 11 and forms an electrical connection, and the second functional segment 22 is electrically connected to the external circuit, so that the conductive element 20 is connected in series with the external circuit. At this time, the contactor 100 is in the conducting state. When the first functional segment 21 moves from the first position to the second position, the first functional segment 21 gradually moves away from the contact portion 11. When the first functional segment 21 is in the second position, the first functional segment 21 is separated from the contact portion 11 and the two are not conducting. The second functional segment 22 is electrically connected to or disconnected from the external circuit. At this time, the contactor 100 is in the disconnected state.

[0047] like Figures 1 to 3 As shown, the movable member 30 is located in the mounting cavity. The movable member 30 can move under the action of external force, so that under the set working conditions, the first functional segment 21 and the second functional segment 22 can be separated through the movable member 30, that is, the conductive member 20 is disconnected from the connection between the first functional segment 21 and the second functional segment 22. At this time, the contactor 100 is also in the open state, thereby disconnecting the loop of the external circuit connected to the contact part 11.

[0048] In other words, even if the first functional segment 21 and the contact portion 11 are in contact to form an electrical connection, as long as the first functional segment 21 and the second functional segment 22 are separated by the movable member 30, the contact portion 11 can be in an open state, thereby disconnecting the loop of the external circuit connected to the contact portion 11, which can effectively improve the reliability of the contactor 100.

[0049] It should be noted that the set operating conditions include, but are not limited to, the following situations: Situation 1: When an overload or short circuit occurs, that is, when the overload exceeds the preset current threshold; Situation 2: When an abnormal signal is received from the outside.

[0050] Therefore, according to the embodiment of the present invention, the contactor 100, by providing a movable member 30, can separate the first functional segment 21 and the second functional segment 22 under a set operating condition. This allows the contactor 100 to not only disconnect the circuit by moving the position of the first functional segment 21, but also to disconnect the circuit by separating the first functional segment 21 and the second functional segment 22 through the movable member 30. Even when the first functional segment 21 of the conductive member 20 is in contact with the contact portion 11, the contactor 100 can still disconnect the circuit, thus effectively improving the reliability and safety of the contactor 100.

[0051] In some examples of the present invention, the mounting cavity is filled with an arc-extinguishing gas, such as nitrogen or argon. The filling gas can extinguish the arc generated when the first functional segment 21 is disconnected from the contact portion 11, or the arc generated when the conductive element 20 is disconnected.

[0052] In some specific embodiments of the present invention, the first end of the second functional segment 22, that is, the end of the second functional segment 22 away from the first functional segment 21, is fixed in the mounting cavity, and the second functional segment 22 is electrically connected to the external circuit.

[0053] In this embodiment, the movable member 30 can be a spring-loaded structure. When the first functional segment 21 is active, the first end of the second functional segment 22 does not move with the first functional segment 21.

[0054] like Figures 1 to 4 As shown, in some examples of the present invention, the conductive element 20 is formed as an elongated sheet.

[0055] According to one embodiment of the present invention, the first functional segment 21 and the second functional segment 22 move synchronously along a first direction.

[0056] In other words, such as Figures 1 to 3 As shown, the conductive component 20 is movable along a first direction, which can be the thickness direction of the conductive component 20. This allows the first functional segment 21 and the second functional segment 22 of the conductive component 20 to move synchronously along the first direction, so that the second functional segment 22 can also be electrically connected or disconnected from the external circuit when it is in motion.

[0057] In some specific embodiments of the present invention, the mounting cavity is provided with two contact portions 11, and the conductive component 20 includes two first functional segments 21, which are disposed on the second functional segment 22, and the two first functional segments 21 are respectively adapted to the corresponding contact portions 11.

[0058] Specifically, such as Figures 1 to 3As shown, the mounting cavity is provided with two contact portions 11, and the two contact portions 11 are spaced apart along a second direction, which can be the length direction of the conductive element 20. The conductive element 20 mainly includes two first functional segments 21 and a second functional segment 22, wherein the two first functional segments 21 are spaced apart along the second direction, the second functional segment 22 is located between the two first functional segments 21, the first end of the second functional segment 22 is connected to one of the first functional segments 21, and the second end of the second functional segment 22 is connected to the other first functional segment 21.

[0059] In this embodiment, the second functional segment 22 is disposed in the mounting cavity in the following two ways, including but not limited to:

[0060] Scenario 1: The second functional segment 22 is movably disposed within the mounting cavity and can move synchronously with the two first functional segments 21. When the first functional segment 21 is in the first position, the two first functional segments 21 respectively contact the corresponding contact portion 11 to form an electrical connection. At this time, the second functional segment 22 is electrically connected to the external circuit through the first functional segment 21 and the contact portion 11. When the first functional segment 21 is in the second position, the two first functional segments 21 are spaced apart from the corresponding contact portion 11, and both the first functional segment 21 and the second functional segment 22 are disconnected from the external circuit.

[0061] Case 2: The second functional segment 22 is fixed inside the mounting cavity and is directly electrically connected to the external circuit. When the first functional segment 21 is in the first position, the two first functional segments 21 are in contact with the corresponding contact part 11 respectively, forming an electrical connection. When the first functional segment 21 is in the second position, the two first functional segments 21 are spaced apart from the corresponding contact part 11 respectively.

[0062] According to one embodiment of the present invention, the conductive element 20 is provided with a breakable portion 23 between the first functional segment 21 and the second functional segment 22.

[0063] In other words, such as Figure 2 and Figure 4 As shown, the mechanical strength of the connection position between the first functional segment 21 and the second functional segment 22 is relatively weak. The part with weak mechanical strength can serve as a breakable point 23. Thus, when the moving part 30 applies a force to the conductive part 20, the conductive part 20 can be disconnected from the breakable point 23. This makes it easier for the moving part 30 to separate the first functional segment 21 and the second functional segment 22. It can effectively ensure that the first functional segment 21 and the second functional segment 22 are separated under the set operating conditions, and can further improve the reliability and safety of the contactor 100.

[0064] In some specific embodiments of the present invention, the conductive element 20 has a first side and a second side disposed opposite to each other in a first direction, and the first side and / or the second side of the conductive element 20 is provided with a groove, and a breakable part 23 is formed at the location of the groove.

[0065] Specifically, such as Figure 2 and Figure 4 As shown, the conductive member 20 has a first side and a second side arranged opposite to each other in a first direction. The first side of the conductive member 20 is provided with a groove that can extend along the width direction of the conductive member 20 and penetrate through the conductive member 20 in the width direction. The groove separates the first functional segment 21 and the second functional segment 22 in the first direction. The second side of the conductive member 20 may also be provided with a groove that extends along the width direction of the conductive member 20. The position of the groove on the second side of the conductive member 20 corresponds to the position of the groove on the first side of the conductive member 20.

[0066] In this embodiment, the thickness of the conductive component 20 at the connection between the first functional segment 21 and the second functional segment 22 can be reduced by the groove, thereby reducing the mechanical strength at the connection between the first functional segment 21 and the second functional segment 22, so that the location of the groove forms a breakable part 23, and the structure is simple and easy to manufacture.

[0067] In some examples of the present invention, the conductive element 20 is provided with a plurality of through holes at the connection between the first functional segment 21 and the second functional segment 22. The plurality of through holes can be distributed along the width direction of the conductive element 20, thereby reducing the mechanical strength at the connection between the first functional segment 21 and the second functional segment 22, and making the area where the plurality of through holes are located form a breakable part 23.

[0068] According to one embodiment of the present invention, the body 10 includes a housing 12 and an electromagnetic device 13. The housing 12 defines a mounting cavity, and the electromagnetic device 13 is disposed in the housing 12 and connected to a conductive member 20 to drive the first functional segment 21 to move.

[0069] In other words, such as Figures 1 to 3 As shown, the main body 10 mainly includes a housing 12 and an electromagnetic device 13. The housing 12 has a mounting cavity and two conductive posts spaced apart along a second direction. The first end of each conductive post forms a contact portion 11 within the mounting cavity, and the second end extends along a first direction to the outside of the housing 12, forming a terminal block for connection to an external circuit. The electromagnetic device 13 is located within the housing 12, with at least a portion of it situated within the mounting cavity and connected to the conductive element 20. The electromagnetic device 13 can drive the first functional segment 21 to move between a first position and a second position. During use, the state of the contactor 100 can be switched using the electromagnetic device 13.

[0070] like Figures 1 to 3As shown, in some examples of the present invention, the housing 12 mainly includes an outer shell 122 and an inner shell 123. The outer shell 122 can be a non-metallic shell, such as an insulating material like plastic. The inner shell 123 can be a ceramic shell, and the inner shell 123 is located inside the outer shell 122. One end of the inner shell 123 in the first direction is an open end. The open end of the inner shell 123 is provided with a yoke plate 124. The inner wall of the inner shell 123 and the yoke plate 124 define an installation cavity. The outer peripheral surface of the conductive post is sintered with an insulating layer and then passes through the yoke plate 124.

[0071] According to one embodiment of the present invention, the outer shell 122 may be formed by connecting two insulating shells with openings, so as to install the inner shell 123 inside the outer shell 122.

[0072] In some specific embodiments of the present invention, the electromagnetic device 13 includes: a coil assembly 131, a push rod 132, and a magnetic core 133. The coil assembly 131 extends along a first direction and is disposed in the housing 12. A magnetic channel extending along the first direction is provided at one end of the coil assembly 131 near the housing 12. The first end of the push rod 132 is connected to the conductive member 20, and the second end of the push rod 132 is movably disposed in the magnetic channel along the first direction. The magnetic core 133 is disposed at the second end of the push rod 132. The coil assembly 131 cooperates with the magnetic core 133 to drive the push rod 132 to move along the first direction.

[0073] Specifically, such as Figures 1 to 3 As shown, the electromagnetic device 13 mainly includes a coil assembly 131, a push rod 132, and a magnetic core 133. The coil assembly 131 forms a columnar structure extending along a first direction. The coil assembly 131 is located on the side of the yoke plate 124 away from the inner shell 123, and a magnetic channel extending along the first direction is provided at the end of the coil assembly 131 near the yoke plate 124. An insulating seat 50 is provided at the first end of the push rod 132, and the conductive element 20 is fixedly connected to the insulating seat 50. The second end of the push rod 132 extends along the first direction and is movably located in the magnetic channel along the first direction. The magnetic core 133 is located at the second end of the push rod 132, and the coil assembly 131 can drive the magnetic core 133 to move along the first direction, thereby driving the push rod 132 to move along the first direction.

[0074] According to one embodiment of the present invention, such as Figures 1 to 3 As shown, the contactor 100 also includes an elastic element 60, which can be a spring. The elastic element 60 is located on the side of the conductive element 20 near the contact portion 11. Specifically, the elastic element 60 is sleeved on the first end of the push rod 132, and one end of the elastic element 60 can be connected to the insulating base 50.

[0075] like Figure 2As shown, when the first functional segment 21 is in the first position, the elastic member 60 is in a compressed state. When the coil 131b is not energized, the elastic member 60 can drive the conductive member 20 away from the contact portion 11, thereby separating the first functional segment 21 from the contact portion 11. This allows the conductive member 20 to move away from the contact portion 11 not only by gravity but also by the elastic force of the elastic member 60.

[0076] In addition, the elastic element 60 can also be disposed on the side of the conductive element 20 away from the contact portion 11. The first end of the elastic element 60 is connected to the insulating seat 50, and the second end of the elastic element 60 is connected to the inner wall of the mounting cavity. When the first functional segment 21 is in the first position, the elastic element 60 is in a stretched state.

[0077] like Figure 3 As shown, in some examples of the present invention, the coil assembly 131 mainly includes a metal shell 131a and a coil 131b. The metal shell 131a is formed as a cylindrical body extending along a first direction. The first end of the metal shell 131a is an open end and is welded to the yoke plate 124. An insulating sleeve is provided on the outer periphery of the metal shell 131a, and the coil 131b is sleeved on the outer periphery of the insulating sleeve. When the coil 131b conducts electricity, it can generate a magnetic force to drive the magnetic core 133. The magnetic core 133 can be driven to move by utilizing the principle of like poles repelling and unlike poles attracting.

[0078] According to one embodiment of the present invention, the first end of the push rod 132 is provided with an installation channel 132a extending in a first direction, and the movable member 30 is provided in the installation channel 132a.

[0079] In other words, such as Figures 1 to 3 As shown, the first end of the push rod 132 is provided with a mounting channel 132a extending in a first direction. The mounting channel 132a is adapted to the movable member 30, and the movable member 30 is disposed in the mounting channel 132a. The arrangement of the movable member 30 includes, but is not limited to, the following situations:

[0080] Scenario 1: The movable part 30 is snapped into the installation channel 132a. Under the set working conditions, the movable part 30 can break free from the constraint of the snapping structure and move toward the conductive part 20, and apply sufficient force to the conductive part 20 to separate the first functional segment 21 and the second functional segment 22. This can prevent the movable part 30 from colliding with the conductive part 20 due to the shaking of the contactor 100.

[0081] Case 2: The movable member 30 is movably disposed in the installation channel 132a along the first direction. Under the set working condition, the movable member 30 can apply sufficient force to the conductive member 20 to separate the first functional segment 21 from the second functional segment 22.

[0082] In some examples of the present invention, a limiting structure is provided in the mounting channel 132a. The limiting structure can constrain the movable part 30 to move in the first direction, so as to avoid the movable part 30 from colliding with the conductive part 20 due to the shaking of the contactor 100, which can effectively ensure the performance of the contactor 100.

[0083] like Figures 1 to 3 As shown, in some other examples of the present invention, the push rod 132 is formed as a tube extending in a first direction, with an installation channel 132a formed on the inner side of the tube, and the magnetic core 133 is fixedly connected to the second end of the push rod 132, thereby closing the second end of the push rod 132 through the magnetic core 133.

[0084] In some specific embodiments of the present invention, the contactor 100 further includes an excitation device 40, which is disposed on the body 10 and is adapted to drive the movable member 30 to move along a first direction under a set working condition, so as to separate the movable member 30 from the first functional segment 21 and the second functional segment 22.

[0085] Specifically, such as Figures 1 to 3 As shown, an excitation device 40 is provided in the installation channel 132a. The excitation device 40 can receive excitation signals from external devices. After receiving the excitation signal, the excitation device 40 can drive the movable part 30 to move in the first direction. Thus, under the set working conditions, sending an excitation signal to the excitation device 40 can cause the movable part 30 to separate the first functional segment 21 and the second functional segment 22, making it more convenient to separate the first functional segment 21 and the second functional segment 22.

[0086] According to one embodiment of the present invention, the excitation device 40 is configured as a gas generating device provided in the mounting channel 132a. The excitation device 40 is adapted to generate driving gas under a set operating condition to drive the movable member 30.

[0087] In other words, the excitation device 40 can be configured as a gas generating device. The following explanation will take the gas generating device as a miniature explosive device as an example.

[0088] like Figure 2 As shown, the gas generating device mainly includes a spark igniter 41 and an explosive charge 42. Both the spark igniter 41 and the explosive charge 42 are located on the side of the movable part 30 away from the conductive part 20. Specifically, the spark igniter 41 is fixedly connected to the inner wall of the installation channel 132a, and the explosive charge 42 is located on the spark igniter 41. After receiving an excitation signal, the spark igniter 41 can detonate the explosive charge 42. After the explosive charge 42 is detonated, it will generate high-pressure gas, i.e., driving gas. The high-pressure gas can drive the movable part 30 to move, so that the movable part 30 disconnects the conductive part 20 from the connection between the first functional section 21 and the second functional section 22, so that the contactor 100 is in the open state, which can effectively improve the reliability of the contactor 100.

[0089] In this embodiment, the mounting channel 132a serves as an air guide channel, and the outer peripheral surface of the movable part 30 can fit against the inner wall surface of the mounting channel 132a to ensure airtightness, so as to facilitate the driving gas to move the movable part 30.

[0090] It should be noted that the pressure of the driving gas is only required to drive the movable part 30 to disconnect the conductive part 20 from the connection between the first functional section 21 and the second functional section 22. The specific pressure can be determined according to actual needs. In other words, the size of the explosive charge 42 can be determined according to actual needs, which will not be elaborated in this embodiment.

[0091] In some examples of the present invention, the excitation device 40 is a telescopic cylinder, which can be a pneumatic cylinder or an electric cylinder. The output end of the telescopic cylinder is connected to the movable part 30. After the telescopic cylinder receives the excitation signal, the output end of the telescopic cylinder drives the movable part 30 to move, so as to disconnect the conductive part 20 from the connection between the first functional segment 21 and the second functional segment 22, so that the contactor 100 is in the disconnected state, which can effectively improve the reliability of the contactor 100.

[0092] In some specific embodiments of the present invention, the movable part 30 is fixed to the mounting channel 132a, and the excitation device 40 can disengage the movable part 30 from the fixed position under a set working condition and drive the movable part 30 to move along the first direction.

[0093] In other words, the movable part 30 can be fixed to the mounting channel 132a by means of interference fit or snap-fit, so as to avoid the movable part 30 colliding with the conductive part 20 due to the shaking of the contactor 100. This can effectively ensure the performance of the contactor 100. Furthermore, under the set working conditions, the excitation device 40 can cause the movable part 30 to disengage from the fixed position and drive the movable part 30 to move along the first direction, so as to disconnect the conductive part 20 from the connection between the first functional segment 21 and the second functional segment 22, so that the contactor 100 is in the disconnected state, which can effectively improve the reliability of the contactor 100.

[0094] According to one embodiment of the present invention, the movable member 30 and the conductive member 20 are spaced apart in a first direction.

[0095] Specifically, such as Figure 2 As shown, in the first direction, there is a certain distance between the movable member 30 and the conductive member 20, which facilitates the excitation device 40 to accelerate the movable member 30, so that the movable member 30 has greater kinetic energy when it contacts the conductive member 20, which makes it easier for the movable member 30 to break the conductive member 20 from the connection between the first functional segment 21 and the second functional segment 22.

[0096] In some specific embodiments of the present invention, the movable member 30 includes a piston part 31 and a punch part 32. The piston part 31 is disposed in the mounting channel 132a and is movable in a first direction under a set working condition. The punch part 32 is disposed at the first end of the piston part 31 and is used to separate the first functional segment 21 and the second functional segment 22.

[0097] In other words, such as Figure 3 As shown, the movable component 30 mainly includes a piston portion 31 and a punch portion 32. The piston portion 31 is adapted to the mounting channel 132a, and the outer peripheral surface of the piston portion 31 is in contact with the outer peripheral surface of the mounting channel 132a, so that the excitation device 40 can drive the piston portion 31 to move under the set working conditions. The punch portion 32 is connected to the end of the piston portion 31 near the conductive component 20, and the punch portion 32 can correspond to the position of the breakable part 23. When the punch portion 32 moves with the piston portion 31, it is convenient for the punch portion 32 to separate the first functional section 21 and the second functional section 22, that is, to disconnect the conductive component 20 from the breakable part 23.

[0098] like Figure 3 As shown, in some examples of the present invention, the punch portion 32 is formed as a thin-walled structure. When the punch portion 32 moves with the piston portion 31, the punch portion 32 with this structure facilitates the separation of the first functional section 21 and the second functional section 22, which can effectively improve the reliability of the contactor 100.

[0099] According to one embodiment of the present invention, a clearance groove 121 adapted to the movable member 30 is provided on the side of the mounting cavity away from the contact portion 11.

[0100] Specifically, such as Figures 1 to 3 As shown, a protrusion 125 extends along a first direction on the side of the mounting cavity away from the contact portion 11. A clearance groove 121 extending along the first direction is provided on the side of the protrusion 125 near the contact portion 11, and the clearance groove 121 is adapted to the punch portion 32 of the movable member 30. When the movable member 30 separates the first functional segment 21 and the second functional segment 22, the protrusion 125 can support the first functional segment 21. The clearance groove 121 corresponds to the position of the punch portion 32, and the second functional segment 22 is located directly above the clearance groove 121. This effectively ensures that the punch portion 32 breaks the conductive element 20. After the punch portion 32 breaks the conductive element 20, at least a portion of the punch portion 32 is located within the clearance groove 121. At this time, the clearance groove 121 effectively restricts the movement of the movable member 30.

[0101] In summary, the contactor 100 according to the embodiments of the present invention, by providing a movable member 30, can separate the first functional segment 21 and the second functional segment 22 under a set operating condition. This allows the contactor 100 to not only disconnect the circuit by moving the position of the first functional segment 21, but also to disconnect the circuit by separating the first functional segment 21 and the second functional segment 22 through the movable member 30. Even when the first functional segment 21 of the conductive member 20 is in contact with the contact portion 11, the contactor 100 can still disconnect the circuit, effectively improving the reliability and safety of the contactor 100.

[0102] Embodiments of the present invention also provide a vehicle including the contactor 100 described in any of the above embodiments, wherein the contactor 100 can be connected to the vehicle's main circuit. In this embodiment, the operating conditions under which the excitation device 40 receives the excitation signal include, but are not limited to, the situations shown in the table below:

[0103]

[0104] Since the contactor 100 according to the embodiment of the present invention can solve the technical problem of low reliability of existing contactors, the use of the contactor 100 in the vehicle according to the embodiment of the present invention can improve the reliability and safety of the vehicle by ensuring that the vehicle's circuit can be disconnected under the set operating conditions.
