[0052] 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 and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0053] Reference is made below Figures 1-12 The contactor 100 according to the embodiments of the present application is described.

[0054] As Figure 3 shown, the contactor 100 of the embodiments of the present application comprises a terminal group, a joint conductor 3, a transmission assembly 4, a first driving coil 5 and a second driving coil 6.

[0055] As Figure 1 shown, one end of the contactor 100 is provided with a terminal group, and the terminal group comprises a first terminal 1 and a second terminal 2 arranged at intervals, as Figure 3 shown, the first terminal 1 and the second terminal 2 can be both designed as terminal posts in specific design, and a high-voltage line can be connected to the terminal posts to realize electrical connection with the contactor 100.

[0056] The terminal group is at least two groups, and the at least two groups of terminal groups are arranged side by side, the joint conductor 3 is connected with the first terminal 1, and the joint conductor 3 and the second terminal 2 are selectively attached. Thus, by adjusting multiple joint conductors 3 at the same time through the contactor 100, the synchronous on-off of multiple groups of first terminals 1 and second terminals 2 can be realized, and the convenience of switching the on-off state of the contactor 100 is ensured.

[0057] 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 be introduced 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 be introduced into the contactor 100 through the second terminal 2 and flow out of the contactor 100 through the first terminal 1.

[0058] That is to say, the terminal groups in the present invention can be set to two groups, three groups or more groups. For example, in a specific design, the terminal groups are set to two groups, and the first terminal 1 may include a positive input terminal and a negative input terminal, and the second terminal 2 may include a positive output terminal and a negative output terminal, wherein the positive input terminal and the positive output terminal can be electrically connected through a connecting conductor 3, and the negative input terminal and the negative output terminal can also be electrically connected through a connecting conductor 3. Therefore, the contactor 100 in the present invention can be constructed as an integrated on-off control structure with positive and negative poles, which has a higher degree of integration and is simpler to control and use.

[0059] The contactor 100 is provided with a transmission assembly 4, which includes a micro switch 41 and a follower 42. The micro switch 41 is in a power connection with the follower 42, which is connected to the bonding conductor 3. Therefore, when the user controls the movement of the micro switch 41, the micro switch 41 can drive the follower 42 to move, thereby driving the bonding conductor 3 to switch the contactor 100 between the on and off states.

[0060] Among them, Figure 3 As shown, the driving coil has a cylindrical body, the wire is circumferentially wound around the outer wall of the cylindrical body, and the wire as a whole extends axially. When a low-voltage current is passed through the wire, the driving coil can generate a magnetic field. The magnetic field generated by the driving coil can act on the micro switch 41. The micro switch 41 is constructed to have a magnetic part, so that the driving coil can drive the micro switch 41 to move.

[0061] The drive coil includes a first drive coil 5 and a second drive coil 6. Low-voltage current can be passed through the first drive coil 5 and the second drive coil 6, so that the first drive coil 5 and the second drive coil 6 can respectively construct a magnetic field. The first drive coil 5 and the second drive coil 6 are used to drive the micro switch 41 to move in the first direction to drive the bonding conductor 3 to engage with the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically connected, so that the contactor 100 can conduct the circuit; the first drive coil 5 and the second drive coil 6 can also be used to drive the micro switch 41 to move in the second direction to drive the bonding conductor 3 to disconnect from the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically disconnected, so that the contactor 100 can disconnect the circuit.

[0062] It can be understood that by providing the first drive coil 5 and the second drive coil 6, and making the first drive coil 5 and the second drive coil 6 drive the micro switch 41 at the same time, the volume of a single drive coil is reduced while being able to push the micro switch 41, so as to facilitate the overall arrangement of the contactor 100, and make the first drive coil 5 and the second drive coil 6 easy to dissipate heat, thereby improving the safety of the contactor 100.

[0063] The contactor 100 of the embodiment of the present invention can drive the micro switch 41 to move through the first drive coil 5 and the second drive coil 6, thereby driving the follower 42 to drive the joining conductor 3 to move, so as to achieve synchronous connection or disconnection of multiple groups of first terminal 1 and second terminal 2, and facilitate heat dissipation of the contactor 100, thereby improving the reliability and safety of the contactor 100.

[0064] In some embodiments, the first drive coil 5 and the second drive coil 6 are spaced apart and distributed, and the micro switch 41 is rotatably installed around the first axis between the first drive coil 5 and the second drive coil 6. Figure 3 As shown, the first drive coil 5 and the second drive coil 6 are arranged in parallel and spaced apart. The ends of the first drive coil 5 and the second drive coil 6 are provided with magnetic parts, and the magnetic parts are made of magnetic conductive material. When the first drive coil 5 and the second drive coil 6 are energized, the first drive coil 5 and the second drive coil 6 generate a magnetic field and construct an electromagnetic space between the first drive coil 5 and the second drive coil 6. The micro switch 41 is arranged in the electromagnetic space, so that the first drive coil 5 and the second drive coil 6 can jointly drive the micro switch 41 to move.

[0065] The first drive coil 5 and the second drive coil 6 are used to drive the micro switch 41 to rotate about the first axis in a first direction, or to drive the micro switch 41 to rotate about the first axis in a second direction. It should be noted that the first direction can be clockwise and the second direction can be counterclockwise, or the first direction can be counterclockwise and the second direction can be clockwise, so that the specific structure of the contactor 100 can be flexibly arranged according to actual needs, improving the rationality of the layout.

[0066] During the specific implementation process, a low-voltage current can be passed through the first drive coil 5 and the second drive coil 6 to generate a positive magnetic field between the first drive coil 5 and the second drive coil 6, so that the micro switch 41 is forced to rotate in the first direction around the first axis, 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 a reverse low-voltage current can be passed through the first drive coil 5 and the second drive coil 6 to generate an opposite magnetic field between the first drive coil 5 and the second drive coil 6, so that the micro switch 41 is forced to rotate in the second direction around the first axis, so that the first terminal 1 and the second terminal 2 are electrically disconnected.

[0067] Through the above arrangement, the first drive coil 5 and the second drive coil 6 can act together on the magnetic drive unit 411, so that the magnetic drive unit 411 has sufficient torque to drive the joining conductor 3 to move, thereby achieving stable switching of the on and off states of the high-voltage line.

[0068] In some embodiments, as shown in Figure 10 The first driving coil 5 includes a first magnetic conducting part 51 and a second magnetic conducting part 52, and the second driving coil 6 includes a third magnetic conducting part 61 and a fourth magnetic conducting part 62. When the first driving coil 5 and the second driving coil 6 are energized, the polarities of the first magnetic conducting part 51 and the second magnetic conducting part 61 are opposite, the polarities of the third magnetic conducting part 61 and the fourth magnetic conducting part 62 are opposite, the polarities of the first magnetic conducting part 51 and the third magnetic conducting part 61 are opposite, and the polarities of the second magnetic conducting part 52 and the fourth magnetic conducting part 62 are opposite.

[0069] That is, as shown in Figure 10 The main body parts of the first magnetic conducting part 51, the second magnetic conducting part 52, the third magnetic conducting part 61 and the fourth magnetic conducting part 62 are configured as plate-shaped structures. The main body part of the first magnetic conducting part 51 and the main body part of the second magnetic conducting part 52 are arranged in abutment at both ends of the first driving coil 5 and abut the end part of the first driving coil 5. The main body part of the third magnetic conducting part 61 and the main body part of the fourth magnetic conducting part 62 are arranged in abutment at both ends of the second driving coil 6 and abut the end part of the second driving coil 6. Thus, when the first driving coil 5 and the second driving coil 6 are energized with low-voltage current, the first magnetic conducting part 51 and the second magnetic conducting part 52 generate opposite polarities, and when the second driving coil 6 is energized with low-voltage current, the third magnetic conducting part 61 and the fourth magnetic conducting part 62 also generate opposite polarities.

[0070] As shown in Figure 10 The main body part of the magnetic conducting part is connected with a folded plate, the folded plate extends into the gap between the first driving coil 5 and the second driving coil 6, the folded plate of the first magnetic conducting part 51 and the folded plate of the third magnetic conducting part 61 are arranged in abutment, and the folded plate of the second magnetic conducting part 52 and the folded plate of the fourth magnetic conducting part 62 are arranged in abutment. By energizing the first driving coil 5 and the second driving coil 6 with low-voltage current, the polarities of the first magnetic conducting part 51 and the third magnetic conducting part 61 are opposite, and the polarities of the second magnetic conducting part 52 and the fourth magnetic conducting part 62 are opposite.

[0071] The microswitch 41 includes a magnetic driving part 411, wherein the first end of the magnetic driving part 411 is located between the first magnetic conducting part 51 and the third magnetic conducting part 61, the second end of the magnetic driving part 411 is located between the second magnetic conducting part 52 and the fourth magnetic conducting part 62, and the polarities of the first end and the second end of the magnetic driving part 411 are the same.

[0072] Specifically, the two ends of the magnetic driving part 411 can be N poles. When the first driving coil 5 and the second driving coil 6 are energized with low-voltage current, the second magnetic conducting part 52 and the third magnetic conducting part 61 can have N poles, and the first magnetic conducting part 51 and the fourth magnetic conducting part 62 can have S poles. Thus, as shown in Figure 4As shown, the first magnetic conducting part 51 and the first end of the magnetic driving part 411 attract each other, the third magnetic conducting part 61 and the first end of the magnetic driving part 411 repel each other, the second magnetic conducting part 52 and the second end of the magnetic driving part 411 repel each other, and the fourth magnetic conducting part 62 and the second end of the magnetic driving part 411 attract each other, so that the magnetic driving part 411 can rotate around the first axis in the first direction (i.e. the counterclockwise direction in Figure 3 ), the first end of the magnetic driving part 411 is adsorbed on the first magnetic conducting part 51, and the second end of the magnetic driving part 411 is adsorbed on the fourth magnetic conducting part 62, so as to connect the first terminal 1 and the second terminal 2.

[0073] Alternatively, as shown in Figure 6 , when the first driving coil 5 and the second driving coil 6 pass through the reverse low-voltage current, the second magnetic conducting part 52 and the third magnetic conducting part 61 can have S poles, and the first magnetic conducting part 51 and the fourth magnetic conducting part 62 can have N poles, so that the first magnetic conducting part 51 and the first end of the magnetic driving part 411 repel each other, the third magnetic conducting part 61 and the first end of the magnetic driving part 411 attract each other, the second magnetic conducting part 52 and the second end of the magnetic driving part 411 attract each other, and the fourth magnetic conducting part 62 and the second end of the magnetic driving part 411 repel each other, so that the magnetic driving part 411 can rotate around the first axis in the second direction (i.e. the clockwise direction in Figure 3 ), so that the first end of the magnetic driving part 411 is adsorbed on the third magnetic conducting part 61, and the second end of the magnetic driving part 411 is adsorbed on the second magnetic conducting part 52, so as to disconnect the first terminal 1 and the second terminal 2.

[0074] In some embodiments, as shown in Figure 11 , the first driving coil 5 includes the first magnetic conducting part 51 and the second magnetic conducting part 52, the second driving coil 6 includes the third magnetic conducting part 61 and the fourth magnetic conducting part 62, when the first driving coil 5 and the second driving coil 6 are energized, the polarity of the first magnetic conducting part 51 and the second magnetic conducting part 52 is opposite, the polarity of the third magnetic conducting part 61 and the fourth magnetic conducting part 62 is opposite, the polarity of the first magnetic conducting part 51 and the third magnetic conducting part 61 is same, and the polarity of the second magnetic conducting part 52 and the fourth magnetic conducting part 62 is same.

[0075] That is, as shown in Figure 11As shown, the main parts of the first magnetic conductive part 51, the second magnetic conductive part 52, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are constructed as a plate-like structure. The main part of the first magnetic conductive part 51 and the main part of the second magnetic conductive part 52 are fitted at both ends of the first drive coil 5 and are arranged opposite to the end of the first drive coil 5. The main parts of the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are fitted at both ends of the second drive coil 6 and are arranged opposite to the end of the second drive coil 6. Therefore, when a low-voltage current is passed through the first drive coil 5 and the second drive coil 6, the first magnetic conductive part 51 and the second magnetic conductive part 52 generate opposite polarities, and when a low-voltage current is passed through the second drive coil 6, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 also generate opposite polarities.

[0076] Among them, such as Figure 11 As shown, the main body of the magnetic conductive part is connected to a folding plate, which extends into the gap between the first drive coil 5 and the second drive coil 6. The folding plate of the first magnetic conductive part 51 and the folding plate of the third magnetic conductive part 61 are arranged opposite to each other, and the folding plate of the second magnetic conductive part 52 and the folding plate of the fourth magnetic conductive part 62 are arranged opposite to each other. By passing a low-voltage current through the first drive coil 5 and the second drive coil 6, the polarity of the first magnetic conductive part 51 and the third magnetic conductive part 61 are made the same, and the polarity of the second magnetic conductive part 52 and the fourth magnetic conductive part 62 are made the same.

[0077] The micro switch 41 includes a magnetic drive part 411, wherein the first end of the magnetic drive part 411 is located between the first magnetic conductive part 51 and the third magnetic conductive part 61, and the second end of the magnetic drive part 411 is located between the second magnetic conductive part 52 and the fourth magnetic conductive part 62. The polarity of the part close to the first drive coil 5 on the first end of the magnetic drive part 411 is opposite to that of the part close to the second drive coil 6, and the polarity of the part close to the first drive coil 5 on the second end of the magnetic drive part 411 is opposite to that of the part close to the second drive coil 6. The polarity of the parts close to the first drive coil 5 at the first end and the second end of the magnetic drive part 411 is the same, and the polarity of the parts close to the second drive coil 6 at the first end and the second end of the magnetic drive part 411 is the same.

[0078] Specifically, the end of the magnetic driving portion 411 facing the first driving coil 5 can be set as the N pole, and the end of the magnetic driving portion 411 facing the second driving coil 6 can be set as the S pole. Further, when the first driving coil 5 and the second driving coil 6 are supplied with a low voltage current, the first magnetic conductive portion 51 and the third magnetic conductive portion 61 can have an S pole, and the second magnetic conductive portion 52 and the fourth magnetic conductive portion 62 can have an N pole. Figure 4As shown, the first magnetic guide 51 and the first end of the magnetic driving part 411 attract each other, the third magnetic guide 61 and the first end of the magnetic driving part 411 repel each other, the second magnetic guide 52 and the second end of the magnetic driving part 411 repel each other, and the fourth magnetic guide 62 and the second end of the magnetic driving part 411 attract each other, so that the magnetic driving part 411 can rotate around the first axis in the first direction (i.e. the counterclockwise direction in Figure 3 ), the first end of the magnetic driving part 411 is adsorbed on the first magnetic guide 51, and the second end of the magnetic driving part 411 is adsorbed on the fourth magnetic guide 62, so as to connect the first terminal 1 and the second terminal 2.

[0079] Alternatively, as shown in Figure 6 , when the first driving coil 5 and the second driving coil 6 pass through the reverse low-voltage current, the first magnetic guide 51 and the third magnetic guide 61 have N poles, and the second magnetic guide 52 and the fourth magnetic guide 62 have S poles, so that the first magnetic guide 51 and the first end of the magnetic driving part 411 repel each other, the third magnetic guide 61 and the first end of the magnetic driving part 411 attract each other, the second magnetic guide 52 and the second end of the magnetic driving part 411 attract each other, and the fourth magnetic guide 62 and the second end of the magnetic driving part 411 repel each other, so that the magnetic driving part 411 can rotate around the first axis in the second direction (i.e. the clockwise direction in Figure 3 ), so that the first end of the magnetic driving part 411 is adsorbed on the third magnetic guide 61, and the second end of the magnetic driving part 411 is adsorbed on the second magnetic guide 52, so as to disconnect the first terminal 1 and the second terminal 2.

[0080] Through the above arrangement, the ends of the magnetic driving part 411 on both sides of the first axis are respectively subjected to opposite forces, so that the magnetic driving part 411 can stably rotate around the first axis, thereby driving the joint conductor 3 to move, thereby realizing stable switching of the high-voltage line on-off state, and the distance between the first driving coil 5 and the second driving coil 6 can be adjusted according to actual needs, so as to adjust the stroke size of the micro switch 41, so that the micro switch 41 has a larger stroke range, and the assembly mode between the micro switch 41 and the driving coil is more flexible and diverse.

[0081] In some embodiments, the first driving coil 5 and the second driving coil 6 are connected in series in the control circuit, so that the first driving coil 5 and the second driving coil 6 can be controlled synchronously by a single voltage signal, thereby improving the reliability of the contactor 100 as a whole.

[0082] In some embodiments, as shown in Figure 9As shown, the transmission assembly 4 further comprises a transmission member 43, the transmission member 43 comprises a first gear portion 431 rotating around the second axis, the first gear portion 431 can be taken as a bevel gear portion or a straight gear portion, the micro switch 41 comprises an arc-shaped tooth portion 412 rotating around the first axis, the first gear portion 431 and the arc-shaped tooth portion 412 are in mesh transmission through the tooth structure. Among them, the arc-shaped tooth portion 412 is fixedly connected with the magnetic driving portion 411, the arc-shaped tooth portion 412 can move together with the magnetic driving portion 411, the arc-shaped tooth portion 412 is configured as a sector structure, and the side away from the first axis of the arc-shaped tooth portion 412 is provided with a tooth structure, the outside of the first gear portion 431 is configured with a tooth structure corresponding to the arc-shaped tooth portion 412, the arc-shaped tooth portion 412 is in mesh with the first gear portion 431, so as to realize transmission.

[0083] That is, as Figure 4 shown, when the first driving coil 5 and the second driving coil 6 drive the magnetic driving portion 411 to move around the first axis in the first direction, the magnetic driving portion 411 drives the arc-shaped tooth portion 412 to move around the first axis in the first direction, the arc-shaped tooth portion 412 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 in communication; as Figure 6 shown, and when the first driving coil 5 and the second driving coil 6 drive the magnetic driving portion 411 to move around the first axis in the second direction, the magnetic driving portion 411 drives the arc-shaped tooth portion 412 to move around the first axis in the second direction, the arc-shaped tooth portion 412 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.

[0084] In some embodiments, as Figure 9 shown, the transmission member 43 further comprises a second gear portion 432 rotating around the second axis, the second gear portion 432 is taken as a straight gear portion, the first gear portion 431 and the second gear portion 432 are connected in end-to-end opposition, and the axes of the first gear portion 431 and the second gear portion 432 coincide, the first gear portion 431 is used to drive the second gear portion 432 to rotate around the second axis, the driven member 42 comprises a rack portion 421, the rack portion 421 is configured as a columnar structure, the rack portion 421 is provided with a tooth structure extending along the length direction, the second gear portion 432 and the rack portion 421 are in mesh transmission through the tooth structure.

[0085] That is, as Figure 5As shown, when the first driving coil 5 and the second driving coil 6 drive the arc-shaped tooth portion 412 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 421 to move 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, Figure 7 As shown, when the first driving coil 5 and the second driving coil 6 drive the arc-shaped tooth portion 412 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 421 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.

[0086] Through the above setting, the rotation of the magnetic driving portion 411 around the first axis is converted into the sliding of the rack portion 421 in the fixed direction, so as to drive the joint conductor 3 to move, thereby realizing the on-off of the first connecting terminal 1 and the second connecting terminal 2, and making the sliding process smooth and stable, reducing the impact force when the joint conductor 3 is engaged with the second connecting terminal 2, thereby reducing the contact closing noise and improving the stability of the contactor 100.

[0087] 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.

[0088] In some embodiments, the rack portion 421 extends vertically, and the upper end of the rack portion 421 is used to be connected with the joint conductor 3, and the side wall of the lower end of the rack portion 421 is provided with a tooth structure engaged with the second gear portion 432. That is, as shown, Figure 3 As shown, the rack portion 421 is installed on one side of the second gear portion 432, the rack portion 421 is configured as a columnar structure, and the side of the rack portion 421 close to the second gear portion 432 is provided with a tooth structure extending vertically, so that the rack portion 421 can be engaged with the second gear portion 432 to be driven.

[0089] 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 421 to move vertically upward through the tooth structure, so as to drive the contact conductor 3 to move upward, 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 421 to move vertically downward through the tooth structure, so as to drive the contact conductor 3 to move downward, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected.

[0090] Through the above arrangement, the side surface of the contact conductor 3 can be attached to the side surface of the input end first connecting terminal 1 and the output end second connecting terminal 2 as a movable contact, thereby reducing the number of movable contacts and making the movable contact have sufficient contact area to reduce the contact resistance of the movable contact, thereby reducing the heating of the contactor 100, reducing energy loss, and reducing the possibility of adhesion of the movable contact.

[0091] Further, as shown in Figure 3 , by arranging a plurality of contact conductors 3 in sequence with the first driving coil 5 and the second driving coil 6 in the up-down direction, and arranging the driving coil 5 and the micro switch 41 in the horizontal direction (left-right direction in Figure 3 , the overall layout of the contactor 100 is uniform, which is beneficial to overall heat dissipation.

[0092] In some embodiments, as shown in Figure 3 , the contact conductor 3 is configured as a plate, and a plurality of contact conductors 3 are arranged, and the plurality of contact conductors 3 correspond to a plurality of groups of first connecting terminals 1 and second connecting terminals 2, respectively, and the plurality of contact conductors 3 are arranged in the axial direction of the driving coil to be uniformly arranged on the upper side of the first driving coil 5 and the second driving coil 6, so that the overall layout of the contactor 100 is reasonable.

[0093] It should be noted that the material of the contact conductor 3 can be selected from composite materials such as soft copper (silver), so that the contact conductor 3 has a larger current-carrying capacity, further reducing the resistance of the contact conductor 3, and at the same time, the hardness of the contact conductor 3 is smaller, reducing the noise in the process of connecting the second connecting terminal 2 and the contact conductor 3.

[0094] And as shown in Figure 9 , the driven part 42 includes a clamping portion 422, the clamping portion 422 has a clamping opening 423 open towards the contact conductor 3, and the side of the clamping portion 422 away from the contact conductor 3 is provided with a groove, and the rack portion 421 is fixed at the inner side wall of the groove, and the rack portion 421 is used to drive the clamping portion 422 to move in the vertical direction. One end of the contact conductor 3 is attached to the first connecting terminal 1, and the other end of the contact conductor 3 extends into the clamping opening 423, and the clamping portion 422 is used to drive the other end of the contact conductor 3 to attach to the second connecting terminal 2.

[0095] Specifically, the first connecting terminal 1 and the second connecting terminal 2 can be arranged at the same height position, and the end of the joint conductor 3 away from the clamping portion 422 extends to the lower side of the first connecting terminal 1, so that the upper side of the joint conductor 3 is connected to the lower side of the first connecting terminal 1, and the end of the joint conductor 3 close to the clamping portion 422 extends into the clamping opening 423, so that the clamping portion 422 can limit the joint conductor 3, and when the rack portion 421 moves, the clamping portion 422 can drive the joint conductor 3 to move in the same direction. The second connecting terminal 2 is arranged at the upper end of the side of the joint conductor 3 close to the clamping portion 422, as shown in FIG. 4, when the joint conductor 3 moves to the upper limit position (i.e., the maximum vertical position), the joint conductor 3 is connected to the second connecting terminal 2, as shown in FIG. 5, and when the clamping portion 422 drives the joint conductor 3 to move downward, the joint conductor 3 is disconnected from the second connecting terminal 2, so that the first connecting terminal 1 and the second connecting terminal 2 are disconnected. Figure 5 Figure 7

[0096] It should be noted that the ends of the plurality of joint conductors 3 extend into the same clamping opening 423, and the clamping portion 422 can drive the plurality of joint conductors 3 to move synchronously, thereby achieving synchronous on-off of multiple groups of the first connecting terminal 1 and the second connecting terminal 2, and reducing the number of parts and the installation difficulty.

[0097] In some embodiments, as shown in FIG. 6, the joint conductor 3 includes a fixed portion 31 and a joint portion 33, the fixed portion 31 is fixedly connected to the first connecting terminal 1, and the driven member 42 is connected to the joint portion 33 to drive the joint portion 33 to engage with the second connecting terminal 2. Figure 5

[0098] It can be understood that when the micro switch 41 rotates around the first axis toward the first direction, the driven member 42 moves away from the second connecting terminal 2, the driven member 42 applies a force to the joint portion 33 away from the second connecting terminal 2, and the fixed portion 31 and the joint portion 33 move relative to each other, so that the joint conductor 3 is disconnected from the second connecting terminal 2; and when the micro switch 41 rotates around the first axis toward the second direction, the driven member 42 moves toward the second connecting terminal 2, and the second connecting terminal 2 and the joint portion 33 are engaged, thereby achieving convenient switching of the high-voltage line on-off state.

[0099] In some embodiments, as shown in FIG. 7, the joint conductor 3 includes a fixed portion 31 and a joint portion 33, the fixed portion 31 is fixedly connected to the first connecting terminal 1, and the driven member 42 is connected to the joint portion 33 to drive the joint portion 33 to engage with the second connecting terminal 2. Figure 5 ​​​As shown, a weakened portion 32 is connected between the fixed portion 31 and the engaging portion 33. Specifically, when the rack portion moves downward, it applies a downward force to the engaging portion 33, causing the weakened portion 32 to elastically deform. This causes relative movement between the fixed portion 31 and the engaging portion 33, disconnecting the engaging conductor 3 from the second output terminal 2. When the micro switch 41 rotates about the first axis in the second direction, the rack portion moves upward, restoring the elastic deformation of the weakened portion 32 and engaging the second output terminal 2 with the engaging portion 33.

[0100] Therefore, by providing the weakened portion 32 to achieve relative movement between the fixing portion 31 and the joining portion 33, plastic deformation of the joining portion 33 is avoided, so that the joining portion 33 can be repeatedly attached to the side of the second terminal 2, thereby improving the stability and reliability of the contactor 100.

[0101] In some embodiments, the weakened portion 32 is constructed as an arc segment, one end of the arc segment is connected to the fixing portion 31, and the other end is connected to the joint portion 33, and the weakened portion 32 has a weakened cavity 321. Figure 5 As shown, the weakened portion 32 may be constructed as a downwardly protruding semicircular arc segment, with the left end of the weakened portion 32 connected to the fixing portion 31 and the right end of the weakened portion 32 connected to the joining portion 33 to jointly construct the joining conductor 3 .

[0102] Furthermore, when the follower 42 applies a downward force to the joint portion 33, the weakened portion 32 compresses and deforms, causing relative movement between the fixed portion 31 and the joint portion 33, disconnecting the joint conductor 3 from the second terminal 2. When the follower 42 moves upward, the elastic deformation of the weakened portion 32 is restored, and the second terminal 2 and the joint portion 33 engage. The provision of an arc-shaped weakened cavity 321 within the weakened portion 32 further reduces the overall stiffness of the weakened portion 32, making it easier for the weakened portion 32 to elastically deform when subjected to the force transmitted by the joint portion 33, thereby reducing the size requirements of the first drive coil 5 and the second drive coil 6.

[0103] In some embodiments, as Figure 1 As shown, the contactor 100 according to the embodiment of the present invention further includes a housing 7. The first terminal 1 and the second terminal 2 are mounted on the housing 7. The engaging conductor 3, the transmission assembly 4, the first drive coil 5 and the second drive coil 6 are all mounted within the housing 7. The driven member 42 is in sliding engagement with the inner circumferential wall of the housing 7.

[0104] That is to say, if Figure 1As shown, the shell 7 is integrally configured as a rectangular structure, and the shell 7 is provided with outwardly protruding feet 71 at opposite corners, the feet 71 are provided with mounting holes 72 penetrating in the thickness direction, and the connecting member can pass through the mounting holes 72 to fix the contactor 100, and the external structure of the shell 7 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 7 is provided with an opening, and the low-voltage signal line can pass out of the shell 7 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.

[0105] Further, as shown in Figure 2 The shell 7 has an outwardly open cavity structure, and the open end is provided with a cover plate structure 73, the cover plate structure 73 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 plate structure 73, so as to be relatively stable with the shell 7, so that the engaging conductor 3 can be relatively moved with the second wiring end 2, and the remaining parts of the first wiring end 1 and the second wiring end 2 and the engaging conductor 3, the transmission assembly 4, the first drive coil 5 and the second drive coil 6 are sealed in the shell 7 through the cover plate structure 73, so as to be separated from the outside, so as to avoid the entry of foreign matter into the shell 7, and at the same time, the function of insulation protection is played. At the same time, the inner circumferential wall of the shell 7 can limit the follower 42, so that the follower 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.

[0106] In some embodiments, the inner circumferential wall of the shell 7 is provided with a sliding guide groove 74, and the rack part 421 of the follower 42 is in sliding cooperation with the sliding guide groove 74. As shown in Figure 8 The sliding guide groove 74 is arranged in the vertical direction, and the opening size of the sliding guide groove 74 is equal to the width size of the rack part 421, when the rack part 421 is installed in the sliding guide groove 74, the sliding guide groove 74 can limit the rack part 421, so that the rack part 421 can reciprocate in the height direction, 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.

[0107] In some embodiments, the contactor of the present application further comprises a sensor configured to detect a circuit signal of the first terminal 1, 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 driving coil 5 and the second driving 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.

[0108] Further, 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 sensor can obtain the change information of the high-voltage circuit during operation (including temperature change, voltage change and current change) and transmit it to the controller in the form of a circuit signal. The controller determines whether the cut-off threshold of the high-voltage circuit is reached according to the circuit signal, and controls the driving assembly to open the electrical connection between the second terminal 2 and the joint conductor 3 when the high-voltage circuit needs to be disconnected. This does not require the use of a fuse, thereby reducing high-voltage loss and cost.

[0109] Further, 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 driving 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 powered by high voltage, thereby improving 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 power 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.

[0110] In some embodiments, the controller is configured to obtain the temperature, voltage or current of the first terminal 1, the second terminal 2 or the joint conductor 3 according to the circuit signal; and the controller is configured to open the electrical connection between the joint conductor 3 and the second terminal 2 when the temperature of the first terminal 1, 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.

[0111] 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.

[0112] 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.

[0113] Specifically, when the sensor is configured as a temperature sensor, the corresponding closing of the electrical connection between the junction conductor 3 and the second terminal 2 when the high-voltage circuit is less than the first temperature threshold, when the sensor is configured as a current sensor, the corresponding closing of the electrical connection between the junction conductor 3 and the second terminal 2 when the high-voltage circuit is less than the first current threshold, when the sensor is configured as a voltage sensor, the corresponding closing of the electrical connection between the junction conductor 3 and the second terminal 2 when the high-voltage circuit is less than the first voltage threshold.
