Description

Technical Field

[0001] This disclosure relates to the field of relay technology, and in particular to a high-voltage DC relay, a control device, and a control circuit module. Background Technology

[0002] A relay is an electronic control device, a switch that controls a load circuit. In related technologies, when signals of different frequencies are input to the high-voltage load terminal, the signals are coupled and conducted along the relay's magnetic conductor and the air medium to the low-voltage coil terminal, generating electromagnetic interference. Furthermore, with technological advancements, the frequency of signals input to the load circuit (such as current frequency) is constantly increasing. If the signals of different frequencies input to the high-voltage load terminal are too strong when coupled along the relay's magnetic conductor and the air medium to the coil terminal, it may affect the operation of other control components in the coil circuit, causing malfunctions and signal interference, thus increasing interference to the coil terminal.

[0046] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0047] A relay is an electronic control device, generally used to control the switching on and off of external high-voltage load circuits. When a relay is operating, its coil terminals are connected to an external control circuit to energize the coil. This external control circuit can be called a low-voltage control circuit or a coil-terminal control circuit. Low voltage and high voltage are relative terms. A relay can also be understood as an "automatic switch" that uses a smaller current to control a larger current, playing roles such as automatic adjustment, safety protection, and circuit switching in load circuits.

[0048] High-voltage DC relays are relays capable of handling high power. Under harsh conditions such as high voltage and high current, high-voltage DC relays have higher reliability and longer service life compared to conventional relays, and are widely used in various fields.

[0049] Taking the application of high-voltage DC relays in the new energy vehicle field as an example, as the requirements for the driving range of new energy vehicles continue to increase, the capacity of car batteries is also required to be higher. The demands for rapid driving, emergency braking, and acceleration from 0 to 100 km / h are also increasing. To meet these requirements, the frequency of the current provided by the battery is constantly increasing, resulting in a wider range of input load current frequencies. For example, inputting signals of different frequencies from 15K to 120MHz at the load end will generate interference signals of different frequencies, such as both low-frequency and high-frequency interference signals. These interference signals can be conducted to the low-voltage control circuit of the relay through magnetic elements and air coupling. If conducted to the coil, they will cause electromagnetic interference to the low-voltage control circuit. Especially when high-frequency signals are input at the load end, the signal conducted to the coil control circuit can become too strong, further affecting the operation of other components in the coil control circuit, causing malfunctions and preventing the relay from working properly. However, related technologies have not effectively solved the above problems.

[0050] Based on this, embodiments of this disclosure provide a relay. For example... Figure 2 , Figures 4 to 7 As shown, where, Figure 2 A perspective view of a relay according to an embodiment of the present disclosure is shown, wherein the housing is omitted. Figure 4 It shows Figure 2 A top-down view. Figure 5 It shows Figure 4 Sectional view along AA, Figure 6 A front view of the relay is shown. Figure 7 A side view of the relay is shown.

[0051] For ease of description, such as Figure 2 As shown, using the assembled relay as a reference standard, the height direction of the relay is defined as the vertical direction Z, the length direction as the first horizontal direction X, and the width direction as the second horizontal direction Y. The vertical direction Z, the first horizontal direction X, and the second horizontal direction Y are perpendicular to each other, and the first horizontal direction X and the second horizontal direction Y can lie in the same plane. This direction is only for the convenience of illustrating the structure of the relay and has no limiting meaning.

[0052] The relay of this embodiment includes a housing (not shown in the figure), a magnetic circuit unit 1, a contact unit 2, and an arc extinguishing unit 3.

[0053] In some embodiments, such as Figure 5As shown, the contact unit 2 includes two stationary contact leads 21, a moving spring 22, an insulating cover 23, a frame 24, and a yoke plate 25. The insulating cover 23, frame 24, and yoke plate 25, when assembled, form a receiving cavity 26. The top of the insulating cover 23 has two through holes, through which the two stationary contact leads 21 pass, with the lower parts of the two stationary contact leads 21 located within the receiving cavity 26.

[0054] Continue to refer to Figure 5 The movable reed 22 is supported in the receiving cavity 26 by the push rod assembly 13 in the magnetic circuit unit 1, and is located below the two stationary contact leads 21. Both ends of the movable reed 22 can serve as movable contacts, which respectively contact the bottom of the two stationary contact leads 21 to achieve contact closure. The tops of the two stationary contact leads 21 are connected to an external load circuit. When the movable contact is closed with the two stationary contact leads 21, the current in the load circuit flows in from one of the stationary contact leads 21, passes through the movable reed 22, and flows out from the other stationary contact lead 21, thus connecting the external load circuit. When the movable contact is separated from the two stationary contact leads 21, the load circuit is broken.

[0055] In this embodiment of the present disclosure, the closing and opening of the moving contact and the two stationary contact lead-out ends 21 are achieved by the movement of the push rod assembly 13 in the magnetic circuit unit 1 driving the moving spring 22.

[0056] Specifically, please refer to Figure 5 The magnetic circuit unit 1 includes a coil 11 and a coil frame 12. The coil frame 12 is a hollow cylindrical shape and is made of insulating material. The coil 11 is wound around the coil frame 12. The magnetic circuit unit 1 also includes a push rod assembly 13, which includes a push rod 131, a support seat 132, and a first spring 133.

[0057] The push rod 131 is axially movable through the coil frame 12, the yoke plate 25, and the receiving cavity 26. A first spring 133 is located at one end of the push rod 131 in the receiving cavity 26, and a support 132 is located at the axial end of the push rod 132 near the movable spring 22. At least a portion of the support 132 is located in the receiving cavity 26. The end of the first spring 133 away from the movable spring 22 abuts against the support 132. The first spring 133 applies an elastic force to the movable spring 22 to move towards the stationary contact lead-out end 21, and after the stationary contact lead-out end 21 contacts the movable spring 22, the first spring 133 can continue to be compressed to provide overtravel.

[0058] The magnetic circuit unit 1 also includes a stationary iron core 14, a moving iron core 15, and a second spring 16. The stationary iron core 14 is disposed within the coil frame 12 and is fixedly connected to the yoke plate 25. A push rod 131 is movably inserted through the stationary iron core 14. The moving iron core 15 is movably disposed within the coil frame 12, opposite to the stationary iron core 14, and is connected to one end of the push rod 131 located within the coil frame 12. When the coil 11 is energized, a magnetic field is generated. The stationary iron core 14 attracts the moving iron core 15, which in turn drives the push rod 131 to move towards the stationary contact lead-out end 21, pushing the moving spring 22 to contact the stationary contact lead-out end 21, thereby connecting the external load circuit. The second spring 16 is disposed between the stationary iron core 14 and the moving iron core 15, and is sleeved around the push rod 131. When the moving iron core 15 moves toward the stationary contact lead-out end 21, the second spring 16 is compressed. When the coil 11 is de-energized, the magnetic field disappears, and the moving iron core 15 is no longer attracted by the stationary iron core 14. The second spring 16 applies a reverse elastic force to the moving iron core 15, causing the moving iron core 15 to quickly reset. The moving spring 22 separates from the stationary contact lead-out end 21, thus disconnecting the external load circuit.

[0059] Therefore, whether coil 11 is energized determines whether the external load circuit is connected or disconnected. For example... Figure 1 As shown, in the embodiment of this disclosure, the relay is connected to an external control circuit 41 when in operation. This control circuit 41 provides current to the coil 11, and therefore plays a crucial role in the normal operation of the relay. This control circuit 41 is the coil terminal control circuit mentioned in the above embodiment, i.e., the low-voltage control circuit. The term "external" in "external control circuit 41" can be understood as meaning not included within the relay.

[0060] like Figure 1 As shown, when the moving spring 22 in this embodiment is closed to the stationary contact lead-out terminal 21, the moving spring 22 actually acts as part of the external load circuit, providing conductivity. Current from the load circuit flows in from one stationary contact lead-out terminal 21, passes through the moving spring 22, and flows out from the other stationary contact. However, due to the load's requirements, the voltage of the external load circuit is much higher than the voltage of the control circuit 41, resulting in the input of signals of different frequencies into the external load circuit. Figure 1 It is known that these signals of different frequencies will be transmitted to the control circuit 41 through magnetic conductive elements (such as moving spring 22, stationary iron core 14, moving iron core 15, etc.), affecting the normal operation of the control circuit 41. Once the control circuit 41 becomes unstable, it will further affect whether the moving spring 22 and the stationary contact lead-out terminal 21 can accurately contact and separate.

[0061] Based on this, such as Figure 1As shown, the relay in this embodiment of the present disclosure also includes an anti-interference element 42, which is connected in series with the coil 11 to form a series connection assembly for electrical connection with an external control circuit 41.

[0062] like Figure 1 As shown, the external control circuit 41 includes a power supply, a resistor 44 (which can be an electronic device), and a switch. Figure 1 (Not shown in the diagram) and wires form a circuit. When the relay is in the working state, the two ends of the coil 11 are connected to the external control circuit 41, so that the coil 11 is connected in series with the resistor 44. The anti-interference element 42 is connected to the control circuit 41, and is connected in series with the coil 11 and the resistor 44.

[0063] In some embodiments, the anti-interference element 42 is at least one of a ferrite bead and an inductor. The ferrite bead is composed of an oxymagnetic material, and the inductor is composed of a magnetic core and a coil. The ferrite bead converts AC signals into heat energy, while the inductor stores the AC signal and releases it slowly. The ferrite bead is mainly used to suppress electromagnetic radiation interference, while the inductor focuses on suppressing conducted interference. Both can suppress high-frequency noise and spike interference, and can primarily absorb or shield high-frequency interference signals.

[0064] Depending on the strength and type of the interference signal, a ferrite bead, an inductor, or both a ferrite bead and an inductor may be selected as the anti-interference element 42. Regarding the specifications of the ferrite bead and inductor, those skilled in the art can also select them according to the specific circumstances of the interference signal; no special limitations are made here.

[0065] In the embodiments of this disclosure, a magnetic bead and / or inductor are disposed in the relay and connected in series with the coil 11. When the relay is working, it can shield interference signals conducted from the external load circuit to the control circuit 41. In particular, it can significantly reduce and shield higher frequency interference signals conducted from the load end to the coil 11, preventing the control circuit 41 from being affected by excessively strong interference signals, thus ensuring the normal operation of the relay. At the same time, when the relay is working, the anti-interference element 42 is also actually connected in series in the control circuit 41, so it will not directly absorb or shield higher frequency interference signals from the external load circuit, ensuring the normal operation of the load circuit.

[0066] like Figure 1 As shown, the relay in this embodiment of the present disclosure also includes a capacitor 43, which is connected to a series assembly formed by the coil 11 and the anti-interference element 42. When the series assembly is connected to an external control circuit 41, the capacitor 43 is not connected in series with the series assembly.

[0067] In some embodiments, such as Figure 1As shown, one end of capacitor 43 is connected to the series assembly, and the other end is grounded.

[0068] Specifically, such as Figure 1 As shown, one end of capacitor 43 can be connected between coil 11 and anti-interference element 42, or it can be connected to one end of the entire series assembly. When the relay is electrically connected to the external control circuit 41, it is sufficient as long as one end of capacitor 43 can be electrically connected to control circuit 41. No special limitation is made here.

[0069] It should be noted that grounding the other end of capacitor 43 can be done by directly grounding the other end of capacitor 43 through a wire when the relay is working, or by connecting the other end of capacitor 43 to other conductors, such as to the conductive material of the relay, and grounding through that conductor.

[0070] In other embodiments, capacitor 43 is connected in parallel with at least one of coil 11 and anti-interference element 42.

[0071] Specifically, capacitor 43 can be connected in parallel with coil 11, in parallel with anti-interference element 42, or in parallel with a series assembly formed by coil 11 and anti-interference element 42. When the relay is electrically connected to the external control circuit 41, capacitor 43 only needs to be connected to the control circuit to achieve the above-mentioned parallel connection, and no special limitation is made here.

[0072] When the relay is in operation, interference signals of different frequencies from the external load circuit will propagate to the control circuit 41, causing the control circuit 41 to carry AC interference signals of different frequencies. Since the capacitor 43 has the characteristic of blocking DC and passing AC, these AC interference signals can be discharged through the capacitor 43, thus simultaneously providing shielding. Therefore, whether one end of the capacitor 43 is grounded or the capacitor 43 is connected in parallel with a series component, the interference signals can be discharged.

[0073] Furthermore, the frequency of the interference signal induced by capacitor 43 is related to the specifications of capacitor 43. The specifications of capacitor 43 can be understood as capacitance. The smaller the specifications of capacitor 43, the easier it is to induce lower frequency interference signals. The interference signal has a frequency range. Both capacitor 43 and anti-interference element 42 can induce or absorb low-frequency and high-frequency interference signals within this frequency range. However, capacitor 43 is more likely to induce lower-frequency interference signals within this frequency range, while anti-interference element is more likely to shield relatively higher-frequency interference signals within this frequency range. The two work together to shield interference signals within all frequency ranges that are conducted to the coil.

[0074] Regarding the specifications of capacitor 43, those skilled in the art can select it according to the frequency of the interference signal; no special limitations are made here.

[0075] Therefore, in this embodiment of the present disclosure, when the relay is working, the anti-interference element 42 is connected in series with the coil 11 to form a series assembly, which can significantly reduce and shield the higher frequency interference signals in the interference signals input from the load end and conducted to the coil 11. The capacitor 43 is connected to the series assembly but not in series with the series assembly, which can significantly reduce and shield the lower frequency interference signals in the interference signals input from the load end and conducted to the coil 11. Thus, it can comprehensively shield interference signals of different frequencies and ensure the normal operation of the relay.

[0076] In some embodiments, such as Figures 8 to 11 As shown, the relay also includes a first connector 51 and a second connector 52 for connecting the anti-interference element 42 and the capacitor 43 to the external control circuit 41. Wherein, Figure 8 A three-dimensional structural schematic diagram of the first connector 51 and the second connector 52 disposed on the coil frame 12 is shown. Figure 9 for Figure 8 The cross-sectional view along the middle BB shows the positional relationship between the first connector 51 and the second connector 52. Figure 10 A three-dimensional structural schematic diagram of the first connector 51 is shown. Figure 11 A three-dimensional structural schematic diagram of the second connector 52 is shown.

[0077] like Figures 8 to 10 As shown, the first connector 51 is conductive and is disposed on the coil frame 12. The first connector 51 has a first end and a second end. The first end is used to connect to one pole of the power supply of the external control circuit 41, and the second end is connected to one end of the anti-interference element 42. The second connector 52 is conductive and is disposed on the coil frame 12. The second connector 52 has a third end and a fourth end. The third end is connected to the other end of the anti-interference element 42, and the fourth end is connected to one end of the coil 11. The other end of the coil 11 is used to connect to the other pole of the power supply of the external control circuit 41, so that the series assembly formed by the coil 11 and the anti-interference element 42 forms a circuit when connected to the external control circuit.

[0078] In some embodiments, such as Figure 8 As shown, the coil frame 12 includes a first flange portion 121, a winding portion 122, and a second flange portion 123. The first flange portion 121 and the second flange portion 123 are located on both sides of the winding portion 122 and protrude outward.

[0079] The winding portion 122 can be a hollow cylinder extending in the vertical direction Z. The first flange portion 121 and the second flange portion 123 are located on opposite sides of the winding portion 122 in the vertical direction Z. The fact that the first flange portion 121 and the second flange portion 123 are located on both sides of the winding portion 122 and protrude outward can be understood as: the first flange portion 121 and the second flange portion 123 extend radially away from the winding portion 122, respectively.

[0080] like Figure 8 and Figure 10 As shown, the first connector 51 has a first lead-out pin 511 and a conductive post 512. The conductive post 512 is vertically connected to one end of the first lead-out pin 511. A portion of the first connector 51 is embedded in the first flange portion 121. The first lead-out pin 511 extends in the vertical direction Z and protrudes from the bottom of the first flange portion 121. The conductive post 512 extends in the first horizontal direction X and protrudes from the side of the first flange portion 121.

[0081] Specifically, in some embodiments, such as Figure 10 As shown, the first lead 511 is plate-shaped and used to connect to the control circuit 41. A conductive post 512 is located at one end of the first lead 511 and is perpendicular to it. The conductive post 512 and the first lead 511 may be integrally formed. The conductive post 512 is used for electrical connection to one end of the anti-interference element 42. In some embodiments, the width of the conductive post 512 is smaller than the width of the first lead 511. (Reference) Figure 9 The width of the conductive post 512 refers to the dimension of the conductive post 512 along the second horizontal direction Y, and the width of the first lead 511 refers to the dimension of the first lead 511 along the second horizontal direction Y. Setting the width of the conductive post 512 to be smaller than the width of the first lead 511 facilitates wiring and saves space and materials.

[0082] The portion of the first lead-out pin 511 extending out of the first flange portion 121 is the first end of the first connector 51, which is used to connect to the control circuit 41. The portion of the conductive post 512 extending out of the first flange portion 121 is the second end of the first connector 51, which is used to connect to one end of the anti-interference element 42.

[0083] In some embodiments, such as Figures 8 to 9 and Figure 11 As shown, the second connector 52 is generally U-shaped and has a first connector 521, a second connector 522 and a third connector 523 connected in sequence. At least the second connector 522 is embedded in the first flange 121 of the coil frame 12. The first connector 521 and the third connector 523 both extend along the first horizontal direction X and protrude from the side of the first flange 121.

[0084] Specifically, such as Figure 11As shown, the second connector 52 is generally U-shaped, and the length of the first connector 521 is less than the length of the third connector 523. (Reference) Figure 9 The length of the first connecting portion 521 refers to its dimension along the first horizontal direction X, and the length of the third connecting portion 523 refers to its dimension along the first horizontal direction X. The third connecting portion 523 has toothed edges on opposite sides along the second horizontal direction Y, which facilitates winding one end of the coil 11 onto the third connecting portion 523 and prevents it from slipping off.

[0085] In some embodiments, the portion of the first connecting part 521 extending out of the first flange 121 is the third end of the second connecting member 52, which is used to connect to the other end of the anti-interference element 42, and the portion of the third connecting part 523 extending out of the first flange 121 is the fourth end of the second connecting member 52, which is used to connect to one end of the coil 11.

[0086] In some embodiments, such as Figure 8 and Figure 9 As shown, the first connector 51 and the second connector 52 are located on the same side of the first flange portion 121, and the first connecting portion 521, the third connecting portion 523 of the second connector 52 and the conductive post 512 of the first connector 51 are spaced apart in the second horizontal direction Y.

[0087] Specifically, the first connector 51 and the second connector 52 are arranged adjacent to each other, such as... Figure 9 As shown, in some embodiments, the projections of the first lead-out pin 511 of the first connector 51 and the second connecting portion 522 of the second connector 52 on the first horizontal direction X at least partially overlap, so as to reduce the distance between the first connecting portion 521 of the first connector 51 and the conductive post 512 of the second connector 52 on the second horizontal direction Y, thereby reducing the space occupied by the control circuit 41 part connecting the anti-interference element 42, making the structure of the relay more compact.

[0088] In some embodiments, such as Figure 8 and Figure 9 A groove 1211 is provided at the edge of the first flange portion 121 corresponding to the edge of the third connecting portion 523, and the third connecting portion 523 extends out from the groove 1211. The third connecting portion 523 is flexible, and when the third connecting portion 523 is connected to one end of the coil 11, the third connecting portion 523 is configured to be bent to extend in the vertical direction Z. That is, one end of the coil 11 can be wound around the third connecting portion 523 to facilitate the electrical connection between the coil 11 and the control circuit 41, and at the same time to facilitate the storage of the end of the coil 11.

[0089] In some embodiments, such as Figure 8 and Figure 9As shown, the relay also includes a third connector 53. The third connector 53 is conductive and is disposed on the coil holder 12. The third connector 53 has a fifth end and a sixth end. The fifth end is connected to the other end of the coil 11, and the sixth end is used to connect to the other pole of the power supply of the external control circuit 41.

[0090] Specifically, such as Figure 8 As shown, the third connector 53 may include a second lead 531 and a winding post 532. The winding post 532 is vertically connected to one end of the second lead 531. A portion of the third connector 53 is embedded in the first flange portion 121 of the coil holder 12. The second lead 531 extends in the vertical direction Z and protrudes from the bottom of the first flange portion 121. The winding portion 122 extends in the first horizontal direction X and protrudes from the side of the first flange portion 121.

[0091] Specifically, in some embodiments, such as Figure 8 As shown, the second lead 531 is plate-shaped and used to connect to the external control circuit 41. The second lead 531 is equivalent to the sixth end of the third connector 53. The structure of the second lead 531 can be the same as that of the first lead 511. The winding post 532 is located at one end of the first lead 511 and is perpendicular to the second lead 531. The winding post 532 and the first lead 511 can be integrally formed. The opposite sides of the winding post 532 along the second horizontal direction Y can be toothed. The winding post 532 is used to connect to the other end of the coil 11, that is, the other end of the coil 11 is wound around the winding post 532, so as to facilitate the electrical connection between the coil 11 and the external control circuit 41, and at the same time, to facilitate the storage of the other end of the coil 11. The winding post 532 is equivalent to the fifth end of the third connector 53.

[0092] In some embodiments, such as Figure 3 As shown, the second end of the first connector 51 is also connected to one end of the capacitor 43, and the other end of the capacitor 43 is grounded.

[0093] In some embodiments, one end of capacitor 43 is connected to the conductive post 512 of the first connector 51 to achieve electrical connection between one end of capacitor 43 and control circuit 41; the other end of capacitor 43 is grounded. Of course, in other embodiments, one end of capacitor 43 may also be connected to the first connection portion 521 of the second connector 52, or one end of capacitor 43 may be directly connected to control circuit 41. As long as one end of capacitor 43 is electrically connected to external control circuit 41 when the relay is working normally, no special limitation is made here.

[0094] Thus, as Figures 1 to 3As shown, when the relay is in the working state, the first lead 511 and the second lead 531 are connected to the control circuit 41. Assuming that the second lead 531 is connected to the positive terminal of the power supply of the control circuit 41, for the anti-interference element 42, the current flows sequentially through the second lead 531 of the third connector 53, the winding post 532, the coil 11, the third connection part 523 of the second connector 52, the second connection part 522, the first connection part 521, the anti-interference element 42, and the conductive post 512 of the first connector 51, and then flows back to the negative terminal of the power supply of the control circuit 41 through the first lead 511 of the first connector 51. For the capacitor 43, the current flows sequentially through the second lead 531 of the third connector 53, the winding post 532, the coil 11, the third connection part 523 of the second connector 52, the second connection part 522, the first connection part 521 of the second connector 52, and the capacitor 43.

[0095] When interference signals from the load circuit are transmitted to the control circuit 41, high-frequency interference signals are absorbed or shielded after passing through the anti-interference element 42, preventing them from interfering with the normal operation of the control circuit 41. Low-frequency interference signals flow into one end of the capacitor 43 and are discharged through it. Therefore, both high-frequency and low-frequency interference signals are eliminated from the control circuit 41, ensuring its stability and guaranteeing the normal operation of the relay.

[0096] In some embodiments, the first connector 51, the second connector 52 and the third connector 53 may also be provided on the second flange portion 123 of the coil frame 12. Those skilled in the art can set them according to the actual situation, and no special limitation is made here.

[0097] like Figures 12 to 15 As shown, in some embodiments, the relay may further include a yoke base 6 and a lead-out member 55. The coil holder 12 is placed on the yoke base 6, and one end of the lead-out member 55 is connected to a side wall of the yoke base 6, while the other end is connected to the other end of the capacitor 43. In some embodiments, the yoke base 6 has at least two opposing first side walls 61 and second side walls 62, and a bottom wall 63 connected to one end of each of the first and second side walls 61 and 62. The first side walls 61, second side walls 62, and bottom wall 63 form a receiving space, in which the coil holder 12 is disposed and placed on the bottom wall 63. One end of the lead-out member 55 is connected to the first side wall 61 of the yoke base 6 near the capacitor 43, and the other end of the lead-out member 55 is connected to the other end of the capacitor 43. The lead-out member 55 is conductive to guide out interference signals absorbed in the capacitor 43.

[0098] Therefore, the yoke 6 acts as a conductor and is connected to the other end of the capacitor 43, thus grounding the capacitor 43. Furthermore, as... Figure 5As shown, the yoke base 6 and the yoke plate 25 form a space for housing the magnetic circuit unit 1. When the coil 11 is energized and generates a magnetic field, the yoke base 6 can prevent the magnetic field from spreading outward, thus improving the utilization rate of the magnetic field.

[0099] In some embodiments, such as Figure 12 As shown, the lead-out member 55 has a first lead-out portion 551, a second lead-out portion 552, and a third lead-out portion 553 connected in sequence. The first lead-out portion 551 and the third lead-out portion 553 are located on opposite sides of the second lead-out portion 552, making the lead-out member 55 approximately "Z" shaped. The lead-out member 55 can be integrally formed. The first lead-out portion 551 is used for fixed connection with the yoke base 6, and the third lead-out portion 553 is used for connection with the capacitor 43.

[0100] like Figure 6 and Figure 13 As shown, the yoke base 6 is U-shaped. The first sidewall 61 and the second sidewall 62 of the yoke are arranged opposite each other in the second horizontal direction Y and extend in the vertical direction Z. The first sidewall 61 is closer to the capacitor 43 than the second sidewall 62. The first sidewall 62 of the yoke base 6 has a receiving groove 611, and the first lead-out portion 551 is fixedly disposed in the receiving groove 611. Specifically, as shown... Figure 13 As shown, the first sidewall 61 near the capacitor 43 has the aforementioned receiving groove 611. This receiving groove 611 is recessed inward from the outer surface of the first sidewall 61. The depth of the receiving groove 611 is defined as the distance from its opening along the second horizontal direction Y to its bottom. The thickness of the first sidewall 61 is the distance along the second horizontal direction Y of the first sidewall 61. Therefore, the depth of the receiving groove 611 is less than the thickness of the first sidewall 61. In other words, the recessed dimension of the receiving groove 611 from its outer surface is less than the thickness of the first sidewall 61. The bottom of the receiving groove 611 is opposite its opening, and this bottom is the remaining portion of the first sidewall 61 after the receiving groove 611 is formed. Additionally, the side of the first sidewall 61 corresponding to the receiving groove 611 also has a notch 612, which communicates with the receiving groove 611 in the second horizontal direction Y.

[0101] like Figure 12 As shown, the first lead-out portion 551 may have a riveting hole 5511, such as Figure 14As shown, the bottom of the receiving groove 611 has another riveting protrusion 6111. The first lead-out portion 551 is placed in the receiving groove 611 and is riveted to the riveting protrusion 6111 at the bottom of the receiving groove 611 through the riveting hole 5511, so that the first lead-out portion 551 is riveted to the first side wall 61 of the yoke base 6. In some embodiments, the first lead-out portion 551 and the third lead-out portion 553 are perpendicular to the second lead-out portion 552, so the above-mentioned notch 612 can make way for the second lead-out portion 552, making the relay structure more compact and reducing the size of the relay. In addition, the third lead-out portion 553 of the lead-out member 55 is connected to the capacitor 43 to conduct the interference signal flowing through the capacitor to the yoke base 6, thereby grounding the other end of the capacitor 43.

[0102] like Figure 3 , Figure 6 and Figure 15 As shown, the relay in this embodiment of the present disclosure also includes a printed circuit board (PCB), an anti-interference element 42 and a capacitor 43 disposed on the PCB. The PCB has a first through hole 541, a second through hole 542 and a third through hole 543. The second end (conductive post 512) of the first connector 51 passes through the first through hole 541 and extends out of the PCB. The third end (first connecting portion 521) of the second connector 52 passes through the second through hole 542 and extends out of the PCB. The third lead-out portion 553 of the lead-out member 55 passes through the third through hole 543 and extends out of the PCB.

[0103] Specifically, capacitor 43 and anti-interference element 42 can be fixed to the same surface of circuit board 54 by soldering, which can be tin soldering. Of course, capacitor 43 and anti-interference element 42 can also be fixed by other connection methods such as screwing or bonding, which are not specifically limited here.

[0104] In some embodiments, the circuit board 54 is welded to the conductive post 512 of the first connector 51, the first connecting portion 521 of the second connector 52, and the third lead-out portion 553 of the lead-out portion 55, respectively. The first connector 51 and the second connector 52 are fixedly connected to the coil frame 12 (e.g., integrally formed with the coil frame 12), and the first lead-out portion 551 of the lead-out portion 55 is riveted to one side wall of the yoke base 6, thereby fixing the circuit board 54. In other embodiments, the circuit board 54 can be fixed to the yoke base 6 by welding, riveting, screwing, or other connection methods. Of course, the circuit board 54 can also be fixedly connected by other methods. Those skilled in the art can set it according to the position and connection relationship of the circuit board 54, and no special limitation is made here. In addition, the circuit board 54 can be set on the outside of the relay housing (not shown in the figure), such as the outer surface of the housing, or it can be set on the inside of the housing, and no special limitation is made here.

[0105] like Figure 2 As shown, the anti-interference element 42 and the capacitor 43 are located on the surface of the circuit board 54 away from the coil holder 12. The anti-interference element 42 is located between the first through hole 541 and the second through hole 542. The first through hole 541 of the circuit board 54 corresponds to the conductive post 512 of the first connector 51, with the conductive post 512 passing through and extending out of the first through hole 541. The second through hole 542 corresponds to the first connecting portion 521 of the second connector 52, with the first connecting portion 521 passing through and extending out of the second through hole 542. Therefore, the anti-interference element 42 is located between the conductive post 512 of the first connector 51 and the first connecting portion 521 of the second connector 52, facilitating the electrical connection of the three. The third through hole 543 corresponds to the third lead-out portion 553 of the third connector 53, with the third lead-out portion 553 passing through and extending out of the third through hole 543. The capacitor 43 is located near the third through hole 543, which facilitates connection to the third lead 553.

[0106] By setting up circuit board 54, the anti-interference element 42 and capacitor 43 can be integrated into a single module, resulting in a compact structure and simplified installation.

[0107] In some embodiments, for further ease of installation, the conductive post 512 of the first connector 51 extends out of the first flange portion 121 by the same dimension as the first connecting portion 521 of the second connector 52 extends out of the first flange portion 121.

[0108] In some embodiments, the coil 11 has an input terminal and an output terminal. When the relay is operating, the anti-interference element 42 and the capacitor 43 are located downstream of the output terminal in the control circuit 41. That is, the current in the control circuit 41 flows through the coil 11 first, and then through the anti-interference element 42 and the capacitor 43.

[0109] Of course, in other embodiments, the anti-interference element 42 and the capacitor 43 may also be located upstream of the input terminal of the coil 11 in the control circuit 41. That is, the current in the control circuit 41 flows through the anti-interference element 42 and the capacitor 43 first, and then flows through the coil 11.

[0110] In some embodiments, the number of anti-interference elements 42 is one, and the number of capacitors 43 is one or more.

[0111] In other embodiments, the number of anti-interference elements 42 is multiple, and the number of capacitors 43 is one or more.

[0112] In some embodiments, the anti-interference element 42 may be a ferrite bead or an inductor. The anti-interference element 42 may also have both a ferrite bead and an inductor, or it may have multiple ferrite beads and multiple inductors. Those skilled in the art can select the appropriate element based on the strength of the interference signal in the actual situation, and no special limitation is made here.

[0113] The study found that for interference signals within a frequency range, the ferrite bead / inductor can primarily reduce and shield the higher-frequency interference signals within that range, while the capacitor 43 can primarily reduce and shield the relatively lower-frequency interference signals within that range. The smaller the capacitor 43's specifications, the easier it is to derive lower-frequency interference signals, and the smaller the specifications of the capacitor 43, the smaller the frequency range of the interference signals it can derive. Therefore, the number of anti-interference elements 42 and capacitors 43 can be determined based on the frequency range of the interference signal and the specifications of the capacitor 43. The number of anti-interference elements 42 can be one or more, and the number of capacitors 43 can also be one or more. Those skilled in the art can set these according to actual conditions; no special limitations are made here.

[0114] In summary, in this embodiment, when the relay is operating, the anti-interference element 42 is connected in series with the coil 11 to form a series assembly. This assembly can significantly reduce and shield interference signals transmitted from the external load circuit to the control circuit 41 connected to the relay. In particular, it can significantly reduce and shield higher-frequency interference signals transmitted from the load end to the coil 11, preventing the control circuit 41 from being affected by excessively strong interference signals and ensuring the normal operation of the relay. Simultaneously, when the relay is operating, the anti-interference element 42 is also actually connected in series with the control circuit 41, thus not directly absorbing or shielding signals from the external load circuit, ensuring the normal operation of the external load circuit. Connecting the capacitor 43 to the series assembly, but not in series with it, can significantly reduce and shield lower-frequency interference signals input from the load end and transmitted to the coil 11, thereby comprehensively shielding interference signals and ensuring the normal operation of the relay.

[0115] like Figure 1 and Figure 5 As shown, the relay in this embodiment further includes an arc-extinguishing unit 3, which is used to extinguish the arc generated between the stationary contact lead-out terminal 21 and the moving spring 22. Figure 5As shown, the arc-extinguishing unit 3 includes two arc-extinguishing magnets 31. The arc-extinguishing magnets 31 can be permanent magnets, and each arc-extinguishing magnet 31 can be approximately cuboid in shape. The two arc-extinguishing magnets 31 are disposed on opposite sides of the insulating cover 23 along the first horizontal direction X. By setting two opposing arc-extinguishing magnets 31, a magnetic field can be formed around the stationary contact lead-out end 21 and the moving spring 22. Therefore, the electric arc generated between the stationary contact lead-out end 21 and the moving spring 22 is elongated in a direction away from each other by the action of the magnetic field, thus extinguishing the arc.

[0116] The arc-extinguishing unit 3 also includes two yoke clips 32, which are positioned corresponding to the two arc-extinguishing magnets 31. Furthermore, the two yoke clips 32 surround the insulating cover 23 and the two arc-extinguishing magnets 31. This design, where the yoke clips 32 surround the arc-extinguishing magnets 31, prevents the magnetic field generated by the arc-extinguishing magnets 31 from spreading outwards and affecting the arc-extinguishing effect. The yoke clips 32 are made of soft magnetic material. Soft magnetic materials can include, but are not limited to, iron, cobalt, nickel, and their alloys.

[0117] like Figure 16 As shown, this embodiment of the present disclosure also provides a control device, including a control circuit 41 and a relay. The relay includes a coil 11, an anti-interference element 42, and a capacitor 43. The anti-interference element 42 is connected in series with the coil 11 to form a series assembly, which is connected in the control circuit 41. The capacitor 43 is connected to the series assembly, but the capacitor 43 and the series assembly are not connected in series in the control circuit 41.

[0118] The relay can be any of the relays described in the above embodiments, and its specific structure will not be repeated here.

[0119] like Figure 16 As shown, the control circuit 41 has a power supply, a resistor 44 (which may be an electronic component), a switch, and wires. Series components are connected in the control circuit 41 to form a current loop. In some embodiments, one end of a capacitor 43 is connected to the control circuit 41, and the other end is grounded. In other embodiments, the capacitor 43 is connected in parallel to the control circuit 41, i.e., the capacitor 43 is connected in parallel with at least one of the anti-interference element 42, the coil 11, and the resistor 44.

[0120] In this embodiment of the control device, when the relay is working, the control circuit 41 is electrically connected to the relay. The anti-interference element 42 can significantly reduce and shield higher-frequency interference signals in the interference signals conducted from the load end to the coil 11, ensuring the normal operation of the relay. Simultaneously, the anti-interference element 42 is connected in series in the control circuit 41 and does not directly absorb or shield signals from the external load circuit, ensuring the normal operation of the external load circuit. Connecting the capacitor 43 to the series assembly, but not in series with it, can significantly reduce and shield low-frequency interference signals in the interference signals input from the load end and conducted to the coil 11, thereby comprehensively shielding interference signals of different frequencies and ensuring the normal operation of the relay.

[0121] like Figure 17 As shown in the illustration, this disclosure also provides a control circuit module 4 for controlling electronic devices. The control circuit module 4 includes a control circuit 41, an anti-interference element 42, and a capacitor 43. The control circuit 41 is electrically connected to the electronic devices. The anti-interference element 42 is electrically connected to the control circuit 41 and is connected in series with the electronic devices. The capacitor 43 is electrically connected to the control circuit 41; when the control circuit 41 is electrically connected to the electronic devices, the capacitor 43 is not connected in series with the electronic devices and the anti-interference element 42.

[0122] Specifically, the control circuit 41 has a power supply, a resistor 44 (which can be an electronic component), a switch, and wires, forming a current loop. In this embodiment, the control circuit 41 has two connection terminals for connecting electronic devices to the control circuit 41, in series with the anti-interference element 42 and the aforementioned resistor 44. One end of the capacitor 43 can be connected to any point in the control circuit 41, and the other end of the capacitor 43 is grounded. Alternatively, the capacitor 43 can be connected in parallel with at least one of the anti-interference element 42 and the resistor 44, or when the control circuit 41 is electrically connected to the electronic device, the capacitor 43 is connected in parallel with the electronic device. The anti-interference element 42 can be a ferrite bead and / or an inductor.

[0123] In some embodiments, the electronic device may be a relay as described in any of the above embodiments, and the control circuit 41 is connected in series with the coil 11 of the relay.

[0124] In this embodiment, the control circuit module 41 is equipped with an anti-interference element 42 and a capacitor 43. When the control circuit 41 is connected to the electronic device, it can completely shield the high and low frequency interference signals transmitted from the external load circuit to the control circuit 41, ensuring the normal operation of the relay.

[0125] Electronic devices can also be other components that are subject to interference signals from external load circuits, such as contactors and circuit breakers. By applying the control circuit module of this embodiment to electronic devices, the influence of external interference signals on electronic devices can be shielded, ensuring the normal operation of electronic devices.
