[0054] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as limiting the present application.

[0055] Reference is made below to Figures 1-14 The contactor 100 according to the embodiments of the present application is described.

[0056] As Figure 3 shown, the contactor 100 of the embodiments of the present application comprises a first wiring terminal 1, a second wiring terminal 2, a joint conductor 3, a transmission assembly 4, and a driving coil 5.

[0057] Among them, as Figure 1 shown, the first wiring terminal 1 and the second wiring terminal 2 are arranged at one end of the contactor 100, as Figure 3 shown, the first wiring terminal 1 and the second wiring terminal 2 can be both designed as a terminal post in the specific design, and a high-voltage wire can be connected to the terminal post to achieve electrical connection with the contactor 100.

[0058] The joint conductor 3 is connected with the first terminal 1, that is, the first terminal 1 is fixedly connected with the joint conductor 3, and the joint conductor 3 is selectively attached with the second terminal 2, so that the first terminal 1 and the second terminal 2 are turned on or off by adjusting the joint conductor 3 of the contactor 100, thereby ensuring the convenience of switching the on-off state of the contactor 100. It should be noted that the first terminal 1 can be set as an input terminal, and the second terminal 2 can be set as an output terminal, so that high-voltage electricity can flow into the contactor 100 through the first terminal 1 and flow out of the contactor 100 through the second terminal 2, or the first terminal 1 can be set as an output terminal, and the second terminal 2 can be set as an input terminal, so that high-voltage electricity can flow into the contactor 100 through the second terminal 2 and flow out of the contactor 100 through the first terminal 1.

[0059] As shown in Figure 9 , the transmission assembly 4 includes a micro switch 41, a driven member 42 and a transmission member 43, the micro switch 41, the driven member 42 and the transmission member 43 are all provided with tooth structures, the tooth structure of the micro switch 41 is used to mesh with the tooth structure of the transmission member 43, when the micro switch 41 moves, the micro switch 41 can drive the driven member 42 to move through the tooth structure; the driven member 42 is arranged apart from the micro switch 41, and the tooth structure of the transmission member 43 meshes with the tooth structure of the driven member 42, when the micro switch 41 drives the transmission member 43 to move, the transmission member 43 can drive the driven member 42 to move through the tooth structure; the driven member 42 is fixedly connected with the movable end of the joint conductor 3, when the driven member 42 moves, the movable end of the joint conductor 3 can move together with the driven member 42.

[0060] It can be understood that by arranging multiple gear transmissions in the transmission assembly 4, the movement of the micro switch 41 transmitted to the joint conductor 3 can be changed in direction during transmission, and the movement of the micro switch 41 can be amplified or reduced, so that the micro switch 41 has a larger stroke range, and the arrangement relationship of the transmission assembly 4 and the joint conductor 3 is more flexible and diverse, thereby realizing the diversification of the overall layout of the contactor 100.

[0061] As shown in Figure 3 , the contactor 100 includes a drive coil 5, the drive coil 5 has a columnar body, a wire is wound around the outer peripheral wall of the columnar body in the circumferential direction, and the wire extends in the axial direction as a whole, when the wire is connected with low-voltage current, the drive coil 5 can generate a magnetic field, the micro switch 41 is configured to have a magnetic part, the magnetic field generated by the drive coil 5 can act on the micro switch 41, so that the drive coil 5 can drive the micro switch 41 to move.

[0062] The micro switch 41 can drive the driven part 42 to move through the transmission part 43 when moving, so as to make the contact conductor 3 contact with the other one of the first terminal 1 and the second terminal 2. It should be noted that the micro switch 41 can be arranged to contact with the second terminal 2 when moving in the first direction, and contact with the other one when moving in the second direction.

[0063] Specifically, the driving coil 5 can be connected with a low-voltage current, so that the driving coil 5 generates a magnetic field, and the micro switch 41 is forced to move in the first direction. At this time, the micro switch 41 drives the contact conductor 3 to move through the driven part 42, so that the first terminal 1 and the second terminal 2 are electrically connected, so that the contactor 100 can conduct the high-voltage circuit; or the driving coil 5 can be connected with a reverse low-voltage current, so that the driving coil 5 generates a reverse magnetic field, and the micro switch 41 is forced to move in the second direction. At this time, the micro switch 41 drives the contact conductor 3 to move reversely through the driven part 42, so that the first terminal 1 and the second terminal 2 are electrically disconnected, so that the contactor 100 can disconnect the high-voltage circuit. Thus, the convenient switching of the high-voltage circuit on-off state is realized.

[0064] It can be understood that when the driving coil 5 is connected with a low-voltage current, the micro switch 41 is forced to start moving, the micro switch 41 drives the transmission part 43 to move through the tooth structure, and the transmission part 43 can drive the driven part 42 through the tooth structure, and the movement of the driven part 42 is relatively stable through the multi-stage gear transmission, so that the movement of the contact conductor 3 is stable, thereby avoiding that the acceleration of the contact conductor 3 is too large, and reducing the impact force of the contact conductor 3 in the process of contact.

[0065] According to the contactor 100 of the embodiment of the application, the multi-stage gear transmission is arranged between the micro switch 41 and the contact conductor 3, so as to amplify or reduce the movement of the micro switch 41, so that the micro switch 41 has a larger stroke range, and when the driving coil 5 drives the micro switch 41, the movement of the contact conductor 3 is stable, and the impact force of the contact conductor 3 when contacting is reduced, so as to reduce the closing noise and improve the stability of the contactor 100.

[0066] In some embodiments, as shown in Figure 3 The micro switch 41 is arranged to be rotatable around a first axis, and the transmission part 43 is arranged to be rotatable around a second axis, and the first axis and the second axis are vertically distributed. The driving coil 5 can drive the micro switch 41 to rotate around the first axis in the first direction, or drive the micro switch 41 to rotate around the first axis in the second direction. The first direction can be taken as the clockwise direction, and the second direction can be taken as the counterclockwise direction, or the first direction can be taken as the counterclockwise direction, and the second direction can be taken as the clockwise direction, so that the specific structure of the contactor 100 can be flexibly arranged according to actual needs.

[0067] Through the above arrangement, the driving coil 5 can drive the microswitch 41 to rotate around the first axis, when the microswitch 41 rotates around the first axis, the transmission member 43 can be driven to rotate around the second axis perpendicular to the first axis, and when the movement of the microswitch 41 is transmitted to the driven member 42, the stroke range of the driven member 42 can be arranged to be staggered in space with the stroke range of the microswitch 41, so as to efficiently utilize the space of the contactor 100, avoid the unilateral dimension of the contactor 100 being too large, and make the overall layout of the contactor 100 more reasonable.

[0068] In some embodiments, as shown in Figure 9 The microswitch 41 includes an arc-shaped tooth portion 411 rotating around the first axis, the arc-shaped tooth portion 411 is configured as a sector structure, and the side away from the first axis of the arc-shaped tooth portion 411 is provided with a tooth structure. The transmission member 43 includes a first gear portion 431 rotating around the second axis, the first gear portion 431 can be configured as a bevel gear portion or a straight gear portion, the tooth structure of the first gear portion 431 corresponds to the tooth structure of the arc-shaped tooth portion 411, so that the arc-shaped tooth portion 411 can be engaged with the first gear portion 431 for transmission.

[0069] That is, as shown in Figure 5 When the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the first direction, the arc-shaped tooth portion 411 can drive the first gear portion 431 to rotate around the second axis through the tooth structure, so as to drive the joint conductor 3 to move, so that the first connecting terminal 1 and the second connecting terminal 2 are connected; as shown in Figure 7 When the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the second direction, the arc-shaped tooth portion 411 can drive the first gear portion 431 to rotate around the second axis through the tooth structure, so as to drive the joint conductor 3 to move reversely, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected.

[0070] In some embodiments, as shown in Figure 9 The transmission member 43 further includes a second gear portion 432 rotating around the second axis, the second gear portion 432 is configured as a straight gear portion, the first gear portion 431 is connected to the end of the second gear portion 432 in opposition, and the axis of the first gear portion 431 coincides with the axis of the second gear portion 432, the first gear portion 431 is used to drive the second gear portion 432 to rotate around the second axis, and the driven member 42 includes a rack portion, the second gear portion 432 is engaged with the rack portion through the tooth structure for transmission.

[0071] That is, as shown in Figure 4 and Figure 5As shown, when the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the first direction, the first gear portion 431 rotates around the second axis to drive the second gear portion 432 to rotate in the same direction, and the second gear portion 432 drives the rack portion to move in the fixed direction to drive the joint conductor 3 to move, so that the first connecting terminal 1 and the second connecting terminal 2 are connected; as shown, Figure 6 and Figure 7 As shown, when the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the second direction, the first gear portion 431 rotates around the second axis to drive the second gear portion 432 to rotate in the same direction, and the second gear portion 432 drives the rack portion to move in the opposite direction to drive the joint conductor 3 to move in the opposite direction, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected.

[0072] Through the above arrangement, the rotation of the driving portion 412 around the first axis is converted into the sliding of the rack portion in the fixed direction to drive the joint conductor 3 to move, so as to realize the on-off of the first connecting terminal 1 and the second connecting terminal 2, and at the same time, the sliding process is smooth and stable, the impact force when the joint conductor 3 is connected with the second connecting terminal 2 is reduced, so as to reduce the contact closing noise and improve the stability of the contactor 100.

[0073] In some embodiments, the diameter of the second gear portion 432 is greater than the diameter of the first gear portion 431. That is, when the first gear portion 431 drives the second gear portion 432 to rotate, the rotation stroke of the second gear portion 432 is greater than the rotation stroke of the first gear portion 431, so that the stroke of the microswitch 41 can be amplified through the transmission member 43, the stroke requirement of the microswitch 41 in the on-off process is reduced, the diversity layout of the whole contactor 100 is facilitated, and the electrical gap requirement of high-voltage electricity is met.

[0074] In some embodiments, the rack portion is configured to extend vertically, and the upper end of the rack portion is used to be connected with the joint conductor 3, and the side wall of the lower end of the rack portion is provided with a tooth structure engaged with the second gear portion 432. That is, as shown, Figure 3 the rack portion is installed on one side of the second gear portion 432, the lower end of the rack portion is configured as a columnar structure extending vertically, and the side of the lower end of the rack portion close to the second gear portion 432 is provided with a tooth structure extending vertically, so that the rack portion can be engaged with the second gear portion 432 for transmission.

[0075] Further, as shown, Figure 3 the upper end of the rack portion is configured as a columnar structure extending horizontally, so that the whole rack portion is configured as a T-shaped structure, and the upper end of the rack portion has a clamping groove open to the joint conductor 3, and the end of the joint conductor 3 can extend into the clamping groove.

[0076] Thus, when the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the first direction, the second gear portion 432 drives the rack portion to move through the tooth structure, so as to drive the joint conductor 3 to move in the same direction, so that the first connecting terminal 1 and the second connecting terminal 2 are connected; and when the driving coil 5 drives the arc-shaped tooth portion 411 to move around the first axis in the second direction, the second gear portion 432 drives the rack portion to move reversely through the tooth structure, so as to drive the joint conductor 3 to move reversely, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected.

[0077] In the specific processing process, the upper end and the lower end of the rack portion can be processed separately, and after the processing is completed, the upper end and the lower end of the rack portion are connected and fixed together, so as to reduce the processing difficulty of the rack portion.

[0078] Specifically, the first connecting terminal 1 and the second connecting terminal 2 can be located at the same height position, and the end of the joint conductor 3 away from the rack portion can extend to the lower side of the first connecting terminal 1, so that the upper side of the joint conductor 3 is connected with the lower side of the first connecting terminal 1, and the end of the joint conductor 3 close to the rack portion can extend into the clamping port, so that the rack portion can limit the joint conductor 3, and when the rack portion moves, the rack portion can drive the joint conductor 3 to move in the same direction, and the second connecting terminal 2 is arranged above the side of the joint conductor 3 close to the rack portion, as shown in Figure 4 , when the joint conductor 3 moves to the upper limit position (i.e. the maximum vertical position), the joint conductor 3 is connected with the second connecting terminal 2, as shown in Figure 6 , and when the rack portion drives the joint conductor 3 to move downward, the joint conductor 3 is disconnected with the second connecting terminal 2, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected.

[0079] Thus, the side surface of the joint conductor 3 can be used to be connected with the side surface of the first connecting terminal 1 and the second connecting terminal 2 as a movable contact, which reduces the number of movable contacts, and makes the movable contact have sufficient joint area, so as to reduce the contact resistance of the movable contact, thereby reducing the heating of the contactor 100, reducing the energy loss, and reducing the possibility of adhesion of the movable contact.

[0080] Further, as shown in Figure 3 , the joint conductor 3 and the driving coil 5 are arranged in sequence in the up-down direction, and the driving coil 5 and the micro switch 41 are arranged in the horizontal direction (i.e. the left-right direction in Figure 3 ), so that the overall layout of the contactor 100 is uniform, which is beneficial to the overall heat dissipation.

[0081] In another embodiment, the rack portion is configured to extend in the lateral direction, and one end of the rack portion is configured to be connected to the engagement conductor 3, and the side wall of the other end of the rack portion is provided with a tooth structure engaged with the second gear portion 432, the first terminal 1 and the second terminal 2 are respectively arranged opposite to the engagement conductor 3 in a first direction, the drive coil 5 and the micro switch 41 are arranged opposite to each other in the first direction, the first terminal 1 and the second terminal 2 are respectively arranged opposite to the drive coil 5 in a second direction, and the engagement conductor 3 and the micro switch 41 are arranged opposite to each other in the second direction, wherein the first direction and the second direction are orthogonal.

[0082] That is, as shown in Figure 11 , the rack portion is mounted on the upper side of the second gear portion 432, and the rack portion is configured to extend in the lateral direction in a columnar structure, and the lower side of the rack portion is provided with a tooth structure arranged in the length direction, and the rack portion can be engaged with the second gear portion 432 to drive. Further, the engagement conductor 3 is arranged at one end of the rack portion in the vertical direction, and the end of the rack portion is pressed against the side wall of the engagement conductor 3.

[0083] Further, when the drive coil 5 drives the micro switch 41 to move around the first axis in the first direction, the rack portion pushes the engagement conductor 3 to move towards the direction close to the output end (the right side of Figure 11 ), and when the engagement conductor 3 extends in the axial direction of the drive coil, the engagement conductor 3 is connected to the output end 2 to connect the input end 1 and the output end 2; and when the drive coil 5 drives the micro switch 41 to move around the first axis in the second direction, the rack portion pushes the engagement conductor 3 to move towards the direction away from the output end (the left side of Figure 11 ), so that the engagement conductor 3 is separated from the output end 2, so that the input end 1 and the output end 2 are disconnected, thereby realizing the switching of the on-off state of the high-voltage line.

[0084] In some embodiments, as shown in Figure 9 , the engagement conductor 3 includes a fixed portion 31 and an engagement portion 33, the fixed portion 31 is fixedly connected to the first terminal 1, and the follower 42 is connected to the engagement portion 33 to drive the engagement portion 33 to engage with the second terminal 2. It should be noted that the material of the engagement conductor 3 can be selected from a composite material such as soft copper (silver), so that the engagement conductor 3 has a larger carrying capacity, further reduces the resistance of the engagement conductor 3, and at the same time, the hardness of the engagement conductor 3 is smaller, which reduces the noise in the engagement process of the second terminal 2 and the engagement conductor 3.

[0085] It can be understood that when the micro switch 41 rotates around the first axis towards the first direction, the rack portion moves downward, the rack portion exerts a downward force on the joint portion 33, so that the joint portion 33 moves downward to disconnect the joint conductor 3 from the second terminal 2; and when the micro switch 41 rotates around the first axis towards the second direction, the rack portion moves upward to drive the joint portion 33 to move upward, so that the second terminal 2 and the joint portion 33 are connected. Thus, the convenient switching of the high-voltage line on-off state is realized.

[0086] In some embodiments, a weakened portion 32 is connected between the fixed portion 31 and the joint portion 33. That is, when the rack portion moves downward, the rack portion exerts a downward force on the joint portion 33, so that the weakened portion 32 elastically deforms, the fixed portion 31 and the joint portion 33 move relative to each other, and the joint conductor 3 is disconnected from the output terminal second terminal 2; and when the micro switch 41 rotates around the first axis towards the second direction, the rack portion moves upward, the elastic deformation of the weakened portion 32 recovers, and the output terminal second terminal 2 and the joint portion 33 are connected.

[0087] Thus, by providing the weakened portion 32, the relative movement of the fixed portion 31 and the joint portion 33 is realized, and plastic deformation of the joint portion 33 is avoided, so that the joint portion 33 can be repeatedly attached to the side of the second terminal 2, thereby improving the stability and reliability of the contactor 100.

[0088] In some embodiments, the weakened portion 32 is configured as an arc-shaped segment, one end of the arc-shaped segment is connected to the fixed portion 31 and the other end is connected to the joint portion 33, and the weakened portion 32 has a weakened cavity 321 therein. That is, as shown in Figure 3 the weakened portion 32 can be configured as a semicircular arc-shaped segment protruding downward, the left end of the weakened portion 32 is connected to the fixed portion 31, and the right end of the weakened portion 32 is connected to the joint portion 33 to jointly configure the joint conductor 3.

[0089] Further, when the driven part 42 exerts a downward force on the joint portion 33, the weakened portion 32 compressively deforms, the fixed portion 31 and the joint portion 33 move relative to each other, and the joint conductor 3 is disconnected from the second terminal 2; and when the driven part 42 moves upward, the elastic deformation of the weakened portion 32 recovers, and the second terminal 2 and the joint portion 33 are connected. Among them, by providing the arc-shaped weakened cavity 321 in the weakened portion 32, the rigidity of the weakened portion 32 as a whole is further reduced, so that the weakened portion 32 is easy to elastically deform when subjected to the force transmitted by the joint portion 33, thereby reducing the size requirement of the driving coil 5.

[0090] In some embodiments, as shown in Figure 3 and Figure 5As shown, the microswitch 41 includes a driving part 412 rotating around a first axis, four corners of the driving part 412 are respectively provided with permanent magnets, two ends of the driving coil 5 are respectively provided with magnetic conductive sheets, the magnetic conductive sheet at one end of the driving coil 5 is adapted to be attracted to the two permanent magnets at one end of the driving part 412, and the magnetic conductive sheet at the other end of the driving coil 5 is adapted to be attracted to the two permanent magnets at the other end of the driving part 412, the polarities of the two permanent magnets at the same end of the driving part 412 are opposite.

[0091] It can be understood that, after the driving coil 5 is powered on, the polarities of the two magnetic conductive sheets at the two ends are opposite, the polarities of the two permanent magnets at the same end of the driving coil 5 are opposite, so that one end of the driving part 412 can move towards the driving coil 5, and the other end moves away from the driving coil 5.

[0092] Of course, the structure of the present application is not limited to this, two permanent magnets can also be arranged at one end of the driving part 412, or one permanent magnet is arranged at each end, so that the permanent magnets are arranged at the corner regions, and the microswitch 41 can be driven to rotate under the action of polar attraction or polar repulsion.

[0093] In this way, by arranging the permanent magnets, the working state of the contactor 100 can be maintained by the magnetic attraction of the permanent magnets, that is, the contactor 100 is kept in the first position or the second position, and the driving coil 5 of the low-voltage control part does not need to be continuously powered on, so as to reduce the low-voltage loss and improve the energy consumption ratio of the contactor 100.

[0094] In some embodiments, the permanent magnet includes a first magnetic pole 413, a second magnetic pole 414, a third magnetic pole 415 and a fourth magnetic pole 416, the first magnetic pole 413 and the second magnetic pole 414 are oppositely arranged at one end of the driving part 412, and the inner side of the first magnetic pole 413 and the inner side of the second magnetic pole 414 are oppositely polarized, the third magnetic pole 415 and the fourth magnetic pole 416 are oppositely arranged at the other end of the driving part 412, and the inner side of the third magnetic pole 415 and the inner side of the second magnetic pole 414 are oppositely polarized, the inner side of the first magnetic pole 413 and the inner side of the third magnetic pole 415 are the same in polarity and close to the driving coil 5, and the inner side of the second magnetic pole 414 and the inner side of the fourth magnetic pole 416 are the same in polarity and away from the driving coil 5; the magnetic conductive sheet includes a first magnetic conductive sheet 51 and a second magnetic conductive sheet 52, one end of the first magnetic conductive sheet 51 is connected to one end of the driving coil 5, the other end of the first magnetic conductive sheet 51 is arranged between the first magnetic pole 413 and the second magnetic pole 414, one end of the second magnetic conductive sheet 52 is connected to the other end of the driving coil 5, and the other end of the second magnetic conductive sheet 52 is arranged between the third magnetic pole 415 and the fourth magnetic pole 416.

[0095] For example, the inner sides of the first magnetic pole 413 and the third magnetic pole 415 can be set as N poles, and the inner sides of the second magnetic pole 414 and the fourth magnetic pole 416 can be set as S poles. When the driving coil 5 is supplied with a positive low-voltage current, the first magnetic conductive sheet 51 is the N pole and the second magnetic conductive sheet 52 is the S pole. At this time, Figure 5 As shown, the first magnetic pole 413 and the second magnetic pole 414 act together to make the first magnetic conductive sheet 51 fit on the inner wall of the second magnetic pole 414, and at the same time, the third magnetic pole 415 and the fourth magnetic pole 416 act together to make the second magnetic conductive sheet 52 fit on the inner wall of the third magnetic pole 415, so as to drive the rack portion to move upward, thereby realizing the connection between the first terminal 1 and the second terminal 2; and when the reverse low-voltage current is passed through the driving coil 5, the first magnetic conductive sheet 51 is the S pole and the second magnetic conductive sheet 52 is the N pole. At this time, as shown in FIG. Figure 7 As shown, the first magnetic pole 413 and the second magnetic pole 414 act together to make the first magnetic conductive sheet 51 adhere to the inner wall of the first magnetic pole 413, and at the same time the third magnetic pole 415 and the fourth magnetic pole 416 act together to make the second magnetic conductive sheet 52 adhere to the inner wall of the fourth magnetic pole 416, so as to drive the follower 42 to move downward, thereby disconnecting the first terminal 1 and the second terminal 2.

[0096] It can be understood that the inner side of the first magnetic pole 413 and the third magnetic pole 415 refers to the opposite side of the first magnetic pole 413 and the third magnetic pole 415; the inner side of the second magnetic pole 414 and the fourth magnetic pole 416 refers to the opposite side of the second magnetic pole 414 and the fourth magnetic pole 416; Figure 13 In the embodiment shown, the permanent magnet is constructed as a plate magnet with polarity distributed as described above. Figure 14 In the embodiment shown, the permanent magnet is configured as a U-shaped magnet, and the open end is formed into two magnetic poles, and the polarity is distributed as described above.

[0097] In some embodiments, as Figure 1 As shown, the contactor 100 according to the embodiment of the present invention further includes a housing 6. The first terminal 1 and the second terminal 2 are mounted on the housing 6. The engaging conductor 3, the transmission assembly 4, the first drive coil 5 and the second drive coil 5 are all mounted within the housing 6. The driven member 42 is in sliding engagement with the inner circumferential wall of the housing 6.

[0098] That is to say, if Figure 1As shown, the shell 6 is integrally configured as a rectangular structure, and the shell 6 is provided with outwardly protruding feet 61 at opposite diagonal positions, the feet 61 are provided with mounting holes 62 penetrating in the thickness direction, and the connecting member can pass through the mounting holes 62 to fix the contactor 100, and the external structure of the shell 6 is consistent with the conventional contactor 100, which is convenient for structural design and material switching. It should be noted that the side wall of the shell 6 is provided with an opening, and the low-voltage signal line can pass out of the shell 6 to be electrically connected with the external power supply, and the operator can control the on-off of the contactor 100 through the external switch. Among them, the low-voltage signal line can also be designed as a connector.

[0099] Further, as shown in the drawings, Figure 2 The shell 6 has an outwardly open cavity structure, and the open end is provided with a cover structure 63, the cover structure 63 is provided with through holes corresponding to the first wiring end 1 and the second wiring end 2, and the upper parts of the first wiring end 1 and the second wiring end 2 can be inserted into the through holes to be mounted on the cover structure 63, so as to be relatively stable with the shell 6, so that the engaging conductor 3 can move relative to the second wiring end 2, and the remaining parts of the first wiring end 1 and the second wiring end 2, as well as the engaging conductor 3, the transmission assembly 4 and the drive coil 5 are sealed in the shell 6 through the cover structure 63, so as to be isolated from the outside, so as to avoid the entry of foreign matter into the shell 6, and at the same time, the function of insulation protection is realized. At the same time, the inner circumferential wall of the shell 6 can limit the driven part 42, so that the driven part 42 can slide along the same direction relative to the inner circumferential wall, so as to ensure the stability of the movement path of the engaging conductor 3, and the reliability of the working process of the contactor 100 is improved.

[0100] In some embodiments, the inner circumferential wall of the shell 6 is provided with a sliding guide groove 64, and the rack part of the driven part 42 is in sliding cooperation with the sliding guide groove 64. As shown in the drawings, Figure 8 The sliding guide groove 64 is arranged along the height direction, and the opening size of the sliding guide groove 64 is equal to the width size of the lower end of the rack part, when the rack part is installed in the sliding guide groove 64, the sliding guide groove 64 can limit the rack part, so that the rack part can move vertically and reciprocally, so as to ensure the reliability of the contact and disengagement process of the engaging conductor 3 and the first wiring end 1, and the stability of the contactor 100 is improved.

[0101] In some embodiments, the contactor of the present application further comprises a sensor configured to detect the circuit signal of the first terminal 1 or the second terminal 2 or the joint conductor 3 in real time; and a controller electrically connected to the sensor and adapted to control the first drive coil 5 and the second drive coil 6 to open or close the electrical connection between the joint conductor 3 and the second terminal 2 according to the circuit signal. That is, the sensor can be configured to monitor the joint conductor 3, or the sensor can be configured to detect the first terminal 1, or the sensor can be configured to detect the second terminal 2, so as to obtain the corresponding circuit signal. It can be understood that, as the first terminal 1 and the second terminal 2 are conducted through the joint conductor 3, the current and heat of the high-voltage circuit will change, and the temperature will change accordingly. The temperature sensor can obtain the change information (including temperature change, voltage change and current change) of the high-voltage circuit during the working process, and transmit the change information to the controller in the form of a circuit signal. The controller determines whether the high-voltage circuit reaches the cut-off threshold according to the circuit signal, and controls the drive assembly to open the electrical connection between the second terminal 2 and the joint conductor 3 when it is necessary to disconnect the high-voltage circuit. In this way, the need for a fuse is eliminated, thereby reducing the loss of high-voltage and reducing the cost.

[0102] Moreover, after the contactor 100 is controlled to be opened, if the electrical equipment using the contactor 100 of the present application needs to continue to work, the controller can control the drive assembly to realize the joint of the second terminal 2 and the joint conductor 3, so as to ensure that the electrical equipment can be supplied with high voltage, thereby improving the safety. For example, when the contactor 100 of the present application is applied to an electric vehicle, if the circuit information indicates that the contactor 100 needs to be disconnected but the vehicle needs to maintain the working condition due to a dangerous situation, the high-voltage supply state can be maintained, and the electrical connection between the second terminal 2 and the joint conductor 3 can be disconnected after the vehicle is driven to a safe position or the dangerous situation is removed.

[0103] In some embodiments, the controller is configured to obtain the temperature or voltage or current of the first terminal 1 or the second terminal 2 or the joint conductor 3 according to the circuit signal; and the controller is configured to disconnect the electrical connection between the joint conductor 3 and the second terminal 2 when the temperature of the first terminal 1 or the second terminal 2 or the joint conductor 3 is greater than a first temperature threshold; and / or the voltage is greater than a first voltage threshold; and / or the current is greater than a first current threshold.

[0104] Specifically, when the sensor is configured as a temperature sensor, the circuit breaking mechanism is triggered when the high-voltage circuit is greater than the first temperature threshold; when the sensor is configured as a current sensor, the circuit breaking mechanism is triggered when the high-voltage circuit is greater than the first current threshold; and when the sensor is configured as a voltage sensor, the circuit breaking mechanism is triggered when the high-voltage circuit is greater than the first voltage threshold.

[0105] In some embodiments, the controller is configured to close the electrical connection between the junction conductor 3 and the second terminal 2 when the temperature of the first terminal 1 or the second terminal 2 or the junction conductor 3 is less than a second temperature threshold; and / or the voltage is less than a second voltage threshold; and / or the current is less than a second current threshold, wherein the second temperature threshold is less than or equal to the first temperature threshold, the second voltage threshold is less than or equal to the first voltage threshold, and the second current threshold is less than or equal to the first current threshold.
