Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of electrical equipment technology, and more specifically, to a contactor. Background Technology

[0002] Contactors are widely used in industrial automation and power systems. They control the movement of a drive mechanism by energizing and de-energizing an electromagnetic coil, which in turn moves the moving contact bracket connected to the drive mechanism to change the switching state of the main circuit.

[0003] However, during the movement of the moving contact support, the drive mechanism of a conventional contactor is prone to tilting due to force, which reduces the reliability and fault tolerance of the mechanical interlock and also increases the friction of the drive mechanism.

[0015] In some embodiments, the pair of first rectangular holes are distributed on both sides of the pin and staggered along the extension direction of the pin, the pair of second rectangular holes are distributed on both sides of the pin and staggered along the extension direction of the pin, and the corresponding first rectangular holes and the corresponding second rectangular holes are arranged along the extension direction of the pin.

Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0040] As described above, the drive mechanism of a conventional contactor includes a slider mechanism and a crank-slider mechanism. The slider mechanism experiences high friction during movement, leading to a high silver point ablation rate and inter-electrode imbalance, which easily causes the mechanism to tilt under stress. Although the crank-slider mechanism can reduce friction during movement, it is still prone to tilting under stress, thereby reducing the reliability and fault tolerance of the mechanical interlock. Based on this, embodiments of this disclosure provide a contactor 100 to at least partially solve the above problems. In the following, [further details will be provided in conjunction with...] Figures 1 to 8 The principles of this disclosure are described.

[0041] Figure 1 A schematic diagram of the structure of a contactor 100 according to some embodiments of the present disclosure is shown. Figure 2 It shows Figure 1 The contactor 100 shown is a cross-sectional view taken along AA. Figure 3 A schematic diagram of the connector 3 and the moving iron core 81 according to some embodiments of the present disclosure is shown. Figures 1 to 3 As shown, the contactor 100 described herein generally includes a mounting base 1, a moving contact assembly 2, a connecting member 3, a mating shaft 4, a limit seat 5, an elastic member 6, a normally closed auxiliary contact 71, a normally open auxiliary contact 72, an electromagnetic assembly 8, and a stationary contact assembly 9. The moving contact assembly 2 can pass through the mounting base 1 and is movable relative to the mounting base 1 along a first direction X. Obviously, when the moving contact assembly 2 moves along the first direction X, the moving contact assembly 2 can move toward the stationary contact assembly 9 to switch the contactor 100 to the closed state.

[0042] refer to Figures 2 to 3 In some embodiments, the connector 3 may be located on one side of the mounting base 1. The moving iron core 81 of the electromagnetic assembly 8 may be connected to the connector 3, and the connector 3 may be connected to the moving contact assembly 2. Thus, when the moving iron core 81 is driven by electromagnetic force, the moving iron core 81 can drive the connector 3 to move along the first direction X, thereby driving the moving contact assembly 2 to move along the first direction X.

[0043] According to embodiments of this disclosure, the connector 3 and the moving iron core 81 can be connected in various possible ways, and the embodiments of this disclosure do not limit this. For example, refer to Figure 3 In some embodiments, the moving iron core 81 can be connected to the connector 3 via a pin 82.

[0044] Continue to refer to Figures 2 to 3 In some embodiments, the connector 3 includes a plurality of mating holes 31. Correspondingly, the mounting base 1 is provided with a plurality of mating shafts 4, and each of the plurality of mating shafts 4 is capable of passing through a corresponding mating hole 31. Each of the plurality of mating shafts 4 includes a mating section 41, that is, each mating shaft 4 includes a mating section 41, wherein the mating section 41 is the portion of the mating shaft 4 located within the corresponding mating hole 31. The mating sections 41 of at least two of the plurality of mating shafts 4 are capable of contacting the corresponding mating holes 31 for guiding the connector 3 to move along a first direction X.

[0045] According to embodiments of this disclosure, the connector 3 is guided to move along the first direction X by the engagement of at least two mating sections 41 of mating shafts 4 with corresponding mating holes 31. When the connector 3 is subjected to force on one side, it is less prone to rotation, thereby reducing imbalance under unilateral force and improving the reliability and fault tolerance of the mechanical interlocking of the contactor 100. Furthermore, the engagement of the mating shafts 4 and mating holes 31 reduces friction in the mechanism, thus lowering the ablation rate of the silver points. Moreover, since the connector 3 is less prone to rotation due to the engagement of the mating shafts 4 and mating holes 31, this configuration also improves the balance of the connector 3, reduces imbalance in inter-electrode overtravel, and avoids losses to the contactor due to electrical life ablation imbalance.

[0046] Continue to refer to Figures 2 to 3 In some embodiments, the connector 3 further includes a first mounting hole 32 and a second mounting hole 33. The contactor 100 may also include a normally closed auxiliary contact 71 and a normally open auxiliary contact 72. The normally closed auxiliary contact 71 may be disposed in the first mounting hole 32, and the normally open auxiliary contact 72 may be disposed in the second mounting hole 33. With the above configuration, since the normally closed auxiliary contact 71 and the normally open auxiliary contact 72 can be directly mounted on the connector 3, rather than indirectly mounted on the connector 3, that is, the normally closed auxiliary contact 71 is equivalent to being an integral structure with the connector 3, thus improving the contact reliability of the normally closed auxiliary contact 71 when it is used as a mirror contact.

[0047] Figure 4 It shows Figure 1 The contactor 100 shown is a cross-sectional view taken along BB. Figure 5 It shows Figure 4 An enlarged schematic diagram of part E of the contactor 100 shown. (Reference) Figures 4 to 5 In some embodiments, the connector 3 further includes a snap-fit ​​hole 34. The moving contact assembly 2 is disposed within the snap-fit ​​hole 34 to be secured by the connector 3.

[0048] Further reference Figures 4 to 5 A contact element 35 can also be provided between the snap-fit ​​hole 34 and the moving contact assembly 2. On the one hand, the contact element 35 can increase the installation firmness of the moving contact assembly 2 and the connecting member 3. On the other hand, the contact element 35 can also prevent friction between the moving contact assembly 2 and the connecting member 3, thereby reducing the frictional force between them, and at the same time, it can also prevent the shedding of chips caused by mutual friction.

[0049] It should be noted that the shape of the mating hole 31 according to the embodiments of this disclosure is not limited. For example, in some embodiments, the mating hole 31 can be a circular hole. In other embodiments, the mating hole 31 can also be a rectangular hole.

[0050] Figure 6 It shows Figure 2 An enlarged schematic diagram of part C of the contactor 100 shown. Figure 2 , Figure 3 as well as Figure 6 As shown, in some embodiments, when the plurality of mating holes 31 include pairs of first circular holes 311, at least two mating shafts 4 each include a first mating section 411; that is, the first mating sections 411 can be arranged in pairs. Each first mating section 411 can at least partially contact the hole wall of the corresponding first circular hole 311. Thus, through the engagement of the pairs of first mating sections 411 and the pairs of first circular holes 311, the connector 3 can move along the first direction X while preventing rotation. Obviously, the mating shaft 4 passing through the pairs of first circular holes 311 among the plurality of mating shafts 4 can be used to restrict the movement of the connector 3.

[0051] Preferably, continue to refer to Figure 3 The pair of first circular holes 311 can be distributed on both sides of the pin 82, and the pair of first circular holes 311 can be staggered along the extension direction of the pin 82 to further ensure the stability of the connector 3 when it moves, thereby preventing the connector 3 from rotating.

[0052] Figure 7 It shows Figure 2 An enlarged schematic diagram of part D of the contactor 100 shown. Figure 2 , Figure 3 as well as Figure 7 As shown, in some embodiments, where the plurality of mating holes 31 also include pairs of second circular holes 312, each of the plurality of mating shafts 4 passing through the pairs of second circular holes 312 further includes a second mating segment 412; that is, the second mating segments 412 can be arranged in pairs. Each second mating segment 412 can be spaced apart from the corresponding second circular hole 312, thus maintaining a sufficiently large gap between the second mating segment 412 and the corresponding second circular hole 312.

[0053] Further reference Figure 3 The paired second circular holes 312 can be distributed on both sides of the pin 82, and the paired second circular holes 312 can be staggered along the extending direction of the pin 82. The corresponding first circular hole 311 and the corresponding second circular hole 312 can be arranged along the extending direction of the pin 82. It can be understood that since the second mating section 412 and the corresponding second circular hole 312 are spaced apart from each other, the mating shaft 4 passing through the paired second circular holes 312 among the multiple mating shafts 4 cannot restrict the movement mode of the connecting member 3, thereby avoiding the possibility of jamming during the movement of the connecting member 3.

[0054] Continue to refer to Figures 2 to 7In some implementations, each second circular hole 312 may include a first portion 3121 and a second portion 3122. The first portion 3121 is closer to the mounting base 1 than the second portion 3122, and the diameter of the first portion 3121 may be smaller than the diameter of the second portion 3122. With the above configuration, the pair of elastic members 6 can each be arranged around a mating shaft 4 of a plurality of mating shafts 4 that passes through the pair of second circular holes 312. One end of each elastic member 6 abuts against the inner surface of the corresponding second portion 3122, and the other end of each elastic member 6 is connected to the limiting seat 5.

[0055] Obviously, the paired elastic elements 6 can drive the moving contact assembly 2 to move away from the stationary contact assembly 9, thereby realizing the opening of the contactor 100. Specifically, as the moving contact assembly 2, the connecting member 3, and the moving iron core 81 all move along the first direction X, the paired elastic elements 6 can be continuously compressed as the connecting member 3 moves, so the paired elastic elements 6 can store energy for breaking the contactor 100.

[0056] The elastic element 6 according to embodiments of this disclosure can be of various types known or available in the future, and the embodiments of this disclosure do not limit this. For example, in some embodiments, the elastic element 6 can be a spring.

[0057] In other embodiments, the contactor 100 according to other embodiments of this disclosure and Figure 2 The contactor 100 shown has a similar structure, the main difference being that the plurality of mating holes 31 only include pairs of first circular holes 311, and do not include pairs of second circular holes 312. The differences between the two will be described in detail below, while identical parts will not be repeated.

[0058] In this embodiment, combined with Figures 6 to 7 It is understood that the multiple mating holes 31 only include pairs of first circular holes 311, and at least two mating shafts 4 each include a first mating section 411; that is, the first mating sections 411 can be arranged in pairs. The diameter of a portion of the adjacent mounting base 1 of each first circular hole 311 can be smaller than the diameter of the portion of the corresponding first circular hole 311 facing away from the mounting base 1.

[0059] Thus, a portion of the adjacent mounting base 1 of each first mating segment 411 can contact the corresponding first circular hole 311. Pairs of elastic elements 6 are each arranged around the mating shaft 4 that passes through the pair of first circular holes 311, meaning that an elastic element 6 can be fitted onto the outer surface of each first mating segment 411 facing away from the mounting base 1. In this embodiment, through the interaction between the pair of first circular holes 311 and the pair of first mating segments 411, the contactor 100 can be opened while preventing the connector 3 from rotating.

[0060] Furthermore, the pairs of first circular holes 311 can be distributed on both sides of the pin 82, and the pairs of first circular holes 311 are staggered along the extension direction of the pin 82.

[0061] According to embodiments of this disclosure, the connector 3 is guided to move along the first direction X by the interaction of a pair of first circular holes 311 and a pair of first mating sections 411. When the connector 3 is under unilateral force, it is less prone to rotation, thereby reducing imbalance under unilateral force and improving the reliability and fault tolerance of the mechanical interlocking of the contactor 100. Furthermore, the engagement of the mating shaft 4 and the mating hole 31 reduces friction in the mechanism, thus lowering the ablation rate of the silver points. Moreover, since the connector 3 is less prone to rotation due to the engagement of the mating shaft 4 and the mating hole 31, this configuration also improves the balance of the connector 3, reduces imbalance in inter-electrode overtravel, and avoids losses to the contactor 100 due to electrical life ablation imbalance.

[0062] In other embodiments, the contactor 100 according to other embodiments of this disclosure and Figure 2 The contactor 100 shown has a similar structure, the main difference being that the plurality of mating holes 31 include a pair of first circular holes 311 and a second circular hole 312. The differences between the two will be described in detail below, while the identical parts will not be repeated.

[0063] In this embodiment, the plurality of mating holes 31 include a second circular hole 312 and a pair of first circular holes 311, and correspondingly, at least two mating shafts 4 include a second mating section 412 and a pair of first mating sections 411.

[0064] Furthermore, combined Figures 6 to 7 It is understood that the diameter of a portion of the adjacent mounting base 1 of each first circular hole 311 can be smaller than the diameter of the portion of the corresponding first circular hole 311 facing away from the mounting base 1. Based on this, a portion of the adjacent mounting base 1 of each first mating segment 411 can contact the corresponding first circular hole 311. Pairs of elastic members 6 are each arranged around the mating shaft 4 of the plurality of mating shafts 4 that passes through the pair of first circular holes 311, that is, an elastic member 6 can be fitted onto the outer surface of the portion of each first mating segment 411 facing away from the mounting base 1.

[0065] Further, refer to Figure 7 The elastic element 6 can also be arranged around one of the multiple mating shafts 4 that passes through a second circular hole 312. This enables the contactor 100 to be opened.

[0066] According to embodiments of this disclosure, the connector 3 is guided to move along the first direction X by the interaction of a pair of first circular holes 311 and a pair of first mating sections 411. When the connector 3 is under unilateral force, it is less prone to rotation, thereby reducing imbalance under unilateral force and improving the reliability and fault tolerance of the mechanical interlocking of the contactor 100. Furthermore, the engagement of the mating shaft 4 and the mating hole 31 reduces friction in the mechanism, thus lowering the ablation rate of the silver points. Moreover, since the connector 3 is less prone to rotation due to the engagement of the mating shaft 4 and the mating hole 31, this configuration also improves the balance of the connector 3, reduces imbalance in inter-electrode overtravel, and avoids losses to the contactor 100 due to electrical life ablation imbalance.

[0067] Figure 8 A schematic diagram of a mating section 41 and a mating hole 31 according to other embodiments of the present disclosure is shown. A contactor 100 according to other embodiments of the present disclosure and... Figure 2 The contactor 100 shown has a similar structure, the main difference being that the plurality of mating holes 31 may include a pair of first rectangular holes 313 and a pair of second rectangular holes 314.

[0068] refer to Figure 8 In this embodiment, at least two mating shafts 4 include a pair of third mating segments 413. A portion of each third mating segment 413 can contact a corresponding first rectangular hole 313 to limit the connector 3 in a second direction Y, wherein the second direction Y is perpendicular to the first direction X.

[0069] Furthermore, at least two mating shafts 4 also include a pair of fourth mating segments 414. A portion of each fourth mating segment 414 contacts a corresponding second rectangular hole 314 to limit the connector 3 in a third direction Z, wherein the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0070] Further reference Figure 8 A pair of first rectangular holes 313 are distributed on both sides of the pin 82, and the pair of first rectangular holes 313 are staggered along the extending direction of the pin 82. A pair of second rectangular holes 314 are distributed on both sides of the pin 82, and the pair of second rectangular holes 314 are staggered along the extending direction of the pin 82. The corresponding first rectangular holes 313 and the corresponding second rectangular holes 314 can be arranged along the extending direction of the pin 82. That is, the pair of first rectangular holes 313 are arranged diagonally opposite each other, and the pair of second rectangular holes 314 are arranged diagonally opposite each other.

[0071] It should be noted that, in order to achieve the tripping of the contactor 100, elastic elements 6 can be installed in at least two of the paired first rectangular holes 313 and paired second rectangular holes 314. The installation method of the elastic elements 6 is similar to... Figure 2 The installation method of the elastic element 6 in the contactor 100 shown is similar, and will not be described again here.

[0072] According to embodiments of this disclosure, the connecting member 3 can be guided to move along the first direction X by the engagement of paired third mating sections 413 with paired first rectangular holes 313 and paired fourth mating sections 414 with paired second rectangular holes 314. When the connecting member 3 is under unilateral force, it is less prone to rotation, thereby reducing imbalance and improving the reliability and fault tolerance of the mechanical interlocking of the contactor 100. Furthermore, it reduces friction in the mechanism, thus lowering the ablation rate of the silver points. Additionally, it improves the balance of the connecting member 3, reducing imbalance in inter-electrode overtravel and preventing losses to the contactor 100 due to electrical life ablation imbalance.

[0073] The design of the mating section 41 and mating hole 31 according to embodiments of the present disclosure can be applied to various contactors to at least partially solve the above-mentioned problems. It should be understood that the design of the mating section 41 and mating hole 31 according to embodiments of the present disclosure can also be applied to other electrical components, and the embodiments of the present disclosure are not limiting in this regard.
