Description

Technical Field

[0001] This application relates to the field of electronic control device technology, and in particular to a relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. In circuits, it plays roles such as automatic adjustment, safety protection, and circuit switching.

[0003] Electronic components are connected to the coil assembly of the relay. However, when electronic components are connected to the coil assembly, the electrical clearance between the connection point of the coil assembly and the electronic components and the yoke assembly may be insufficient, resulting in voltage breakdown. This leads to the failure of the electronic components and thus the failure of the relay. Utility Model Content

[0004] Therefore, it is necessary to provide a relay to address the problem that insufficient electrical clearance between the connection point of the coil assembly and electronic assembly and the yoke assembly in conventional technologies leads to voltage breakdown, which in turn causes the electronic assembly to fail and thus the relay to fail.

[0005] The technical solution is as follows:

[0006] One embodiment provides a relay comprising:

[0007] Yoke assembly;

[0008] A coil assembly, at least a portion of which is disposed within the yoke assembly;

[0009] Electronic components, which are electrically connected to the coil assembly; and

[0010] A partition module is located between the connection between the electronic component and the coil component and the yoke component.

[0011] In the aforementioned relay, when a tip discharge occurs at the connection point between the coil assembly and the electronic assembly (hereinafter referred to as the connection point), the isolation module can isolate the connection point from the yoke assembly, preventing voltage breakdown due to insufficient electrical clearance between the coil assembly and the yoke assembly, which could lead to electronic component failure and ultimately relay failure. By setting the isolation module, the relay avoids voltage breakdown, eliminating the need to maintain an insulation distance between the connection point and the yoke assembly. This improves the internal space utilization of the relay, facilitates miniaturization, and enhances installation flexibility.

[0012] In one embodiment, the partition module includes a first partition and a second partition, the yoke assembly has adjacent first and second inner walls, the first partition is located between the connection between the electronic assembly and the coil assembly and the first inner wall, and the second partition is located between the connection between the electronic assembly and the coil assembly and the second inner wall.

[0013] The first partition can isolate the connection point from the first inner wall of the yoke assembly, and the second partition can isolate the connection point from the second inner wall of the yoke assembly, thereby ensuring the isolation effect of the partition module between the connection point and the yoke assembly.

[0014] In one embodiment, the coil assembly includes a coil frame, the coil frame including a flange, a winding portion and a pin, the flange being disposed at one axial end of the winding portion, the pin being disposed on the flange and electrically connected to the electronic component, and the side of the flange away from the winding portion being disposed towards the first inner wall and connected to the first partition.

[0015] A flange is provided on the winding part, and the side of the flange away from the winding part is disposed facing the first inner wall of the yoke assembly. A first partition is provided on the flange to isolate the connection between the pin and the electronic component and the first inner wall of the yoke assembly. The connection between the first partition and the platform of the flange ensures the installation reliability of the partition module.

[0016] In one embodiment, the electronic component has a first through-hole, and the end of the pin away from the flange extends toward the second partition and through the first through-hole.

[0017] One end of the pin passes through the first through-hole of the electronic component to achieve an electrical connection with the electronic component, ensuring a reliable connection.

[0018] In one embodiment, the partition module further includes a first partition rib, which is disposed on the side of the second partition member facing away from the second inner wall. The first partition rib, the second partition member, and the first partition member surround to form a receiving groove, which communicates with the first through hole. The end of the pin away from the flange is located in the receiving groove.

[0019] The end of the pin away from the flange passes through the first through hole and is located in the receiving groove. The receiving groove can provide more reliable isolation and insulation for the connection between the pin and the electronic component, preventing discharge at the connection between the pin and the electronic component from affecting the yoke assembly.

[0020] In one embodiment, the partition module further includes at least one second partition rib, which is disposed in the receiving groove and divides the receiving groove into at least two receiving spaces. The pins and the first through holes are each provided with at least two and are arranged in a one-to-one correspondence. All the pins are arranged in a one-to-one correspondence with the receiving spaces.

[0021] The second partition rib provided in the receiving groove can divide the receiving groove into at least two receiving spaces. The at least two receiving spaces can accommodate at least two pins away from the flange in a one-to-one correspondence, so as to avoid mutual interference between the connection points of each pin and the electronic component, and further improve the isolation effect of the isolation module.

[0022] In one embodiment, the partition module further includes a third partition rib, which is disposed on the side of the second partition member facing away from the second inner wall. The third partition rib, the second partition member, and the first partition rib surround to form a dispensing groove. The opening of the dispensing groove faces the electronic component and is used to accommodate the fixing adhesive. The second partition member is connected to the electronic component through the fixing adhesive.

[0023] The adhesive in the dispensing groove can fix the electronic components to achieve the connection between the electronic components and the second partition, and prevent the electrical connection from failing due to concentrated force at the connection between the electronic components and the pins.

[0024] In one embodiment, the second partition member is further provided with an adhesive outlet, which is connected to the adhesive groove.

[0025] This setup allows for the addition of fixing adhesive to the dispensing groove through the dispensing port, simplifying the implementation and improving the overall assembly efficiency of the relay.

[0026] In one embodiment, the second partition member has a first positioning protrusion, and the electronic component has a first positioning hole, the first positioning protrusion being inserted into the first positioning hole; or / and

[0027] The second partition member has a second positioning hole, and the electronic component has a second positioning protrusion, which is inserted into the second positioning hole; or / and,

[0028] The flange is provided with a third positioning protrusion, and the electronic component is provided with a third positioning hole, wherein the third positioning protrusion is inserted into the third positioning hole.

[0029] The first positioning protrusion on the second partition can be inserted into the first positioning hole on the electronic component to achieve positioning between the second partition and the electronic component. This prevents electrical connection failure due to force concentration at the connection between the electronic component and the pin, and also provides auxiliary positioning for the electronic component before adding fixing glue to the dispensing groove through the dispensing port, preventing displacement of the electronic component during the process of adding fixing glue to the dispensing groove, which would affect the fixing effect of the fixing glue. The second positioning hole is similar to the second positioning protrusion, and will not be described in detail here. The third positioning protrusion on the flange is inserted into the third positioning hole on the electronic component to provide a certain positioning effect for the electronic component.

[0030] In one embodiment, the flange has a positioning groove, and at least a portion of the first partition member is disposed in the positioning groove and is positioned and engaged with the positioning groove.

[0031] The positioning groove on the table can engage with at least part of the first partition to prevent the first partition from moving relative to the table and causing a change in the position of the partition module, thus ensuring the reliability of the partition effect of the partition module.

[0032] In one embodiment, the first partition member has an abutting protrusion on the side facing the first inner wall, and the abutting protrusion abuts against the first inner wall.

[0033] To improve the internal space utilization of the relay, the first inner wall of the yoke assembly needs to fit against the side of the first partition member facing the first inner wall. However, due to the tolerances between the various parts, as the first inner wall gradually approaches the first partition member, the tolerances between the first inner wall of the yoke assembly and the partition member can cause the first inner wall to fail to fit against the first partition member, resulting in an uneven yoke assembly and affecting the assembly effect of the relay. By providing an abutting protrusion on the side of the first partition member facing the first inner wall, as the first inner wall gradually approaches the first partition member, the abutting protrusion on the first partition member can abut against the first inner wall and be squeezed and deformed by the first inner wall, thereby avoiding the unevenness of the yoke assembly caused by the tolerances between the parts and ensuring the assembly effect.

[0034] In one embodiment, the first partition member has a first groove; or / and,

[0035] The second partition has a second groove.

[0036] The first groove can release structural stress while reducing the weight of the first partition and prevent the first partition from deforming; similarly, the second groove can release structural stress while reducing the weight of the second partition and prevent the second partition from deforming.

[0037] In one embodiment, the first partition and the second partition are integrally formed; or / and,

[0038] The first partition and the second partition are arranged at an angle.

[0039] The first and second partition components are integrally molded, which not only facilitates processing but also improves the overall strength of the partition module. The first and second partition components are set at an angle to match the angled first and second inner walls of the yoke assembly, ensuring the partition effect.

[0040] In one embodiment, the electronic component includes a circuit board, with the second spacer located between the circuit board and the yoke assembly; or / and,

[0041] The electronic assembly includes a circuit board and electronic components. The circuit board is electrically connected to the coil assembly, and the electronic components are disposed on the side of the circuit board facing away from the coil assembly. The second partition is also located between the electronic components and the yoke assembly; or / and,

[0042] The electronic component includes a circuit board and electronic elements. The circuit board is electrically connected to the coil assembly, and the electronic elements are disposed on the side of the circuit board facing the coil assembly.

[0043] The second partition is located between the electronic components and the yoke assembly to ensure the isolation effect between the electronic components and the yoke assembly; the electronic components are arranged on the side of the circuit board facing the coil assembly, away from the second inner wall of the yoke assembly, thereby preventing the electronic components from generating discharge phenomena that could damage the yoke assembly.

[0044] In one embodiment, the direction of the connection between the electronic component and the coil component toward the yoke component is defined as a first direction, and the projections of the connection between the electronic component and the coil component, the isolation module, and the yoke component along the first direction at least partially overlap.

[0045] This configuration effectively isolates the connection points between the electronic components and the coil components, as well as between the yoke components, preventing voltage breakdown.

[0046] In one embodiment, the partition module is supported by an insulating material.

[0047] The partition module is made of insulating material to ensure electrical isolation.

[0048] In one embodiment, the electronic component is soldered to the coil assembly.

[0049] During the soldering process between the coil assembly and the electronic assembly, burrs may be generated at the connection point due to the sharpening of the connection, leading to the occurrence of tip discharge. Tip discharge can cause high-temperature erosion of the yoke assembly outside the coil assembly, thereby affecting the magnetic circuit optimization performance of the yoke assembly. An isolation module is installed between the connection point of the electronic assembly and the coil assembly and the yoke assembly to prevent tip discharge from affecting the yoke assembly.

[0069] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0073] Please see Figures 1 to 5 One embodiment of this application provides a relay including a yoke assembly 100, a coil assembly 200, an electronic assembly 300, and an isolation module 400. At least a portion of the coil assembly 200 is disposed within the yoke assembly 100. The electronic assembly 300 is electrically connected to the coil assembly 200. The isolation module 400 is located between the connection between the electronic assembly 300 and the coil assembly 200 and the yoke assembly 100.

[0074] In the aforementioned relay, when a tip discharge occurs at the connection point between the coil assembly 200 and the electronic assembly 300 (hereinafter referred to as the connection point), the isolation module 400 can isolate the connection point from the yoke assembly 100, preventing voltage breakdown due to insufficient electrical clearance between the coil assembly 200 and the yoke assembly 100, which would lead to the failure of the electronic assembly 300 and consequently the relay. By setting the isolation module 400, the relay avoids voltage breakdown, eliminating the need to maintain an insulation distance between the connection point and the yoke assembly 100. This improves the internal space utilization of the relay, facilitates miniaturization of the relay, and enhances the installation flexibility of the relay.

[0075] Furthermore, the coil assembly 200 and the electronic assembly 300 are electrically connected by welding, preferably by soldering.

[0076] For explanation, the isolation module 400 is capable of electrical isolation to prevent discharge at the connection between the coil assembly 200 and the electronic assembly 300 from affecting the yoke assembly 100.

[0077] During the soldering (especially soldering) of the coil assembly 200 and the electronic assembly 300, burrs may be generated at the connection due to the sharpening of the connection, resulting in the occurrence of tip discharge. The tip discharge phenomenon can cause high-temperature ablation of the yoke assembly 100 outside the coil assembly 200, thereby affecting the magnetic circuit optimization performance of the yoke assembly 100. In this application, a partition module 400 is provided between the connection between the electronic assembly 300 and the coil assembly 200 and the yoke assembly 100 to prevent the tip discharge phenomenon at the connection from affecting the yoke assembly 100.

[0078] Furthermore, the partition module 400 should at least isolate the connection point from the yoke assembly 100. Preferably, the partition area of ​​the partition module 400 can also be increased to further ensure the partition effect.

[0079] In one embodiment, the isolation module 400 is made of insulating material to ensure electrical isolation.

[0080] Optionally, the electronic component 300 in the above embodiments may be a circuit board, a varistor, or a thermistor, etc., and no specific limitation is made here.

[0081] Please see Figure 3 In one embodiment, the yoke assembly 100 has a mounting space 110, at least a portion of the coil assembly 200 is disposed within the mounting space 110 of the yoke assembly 100, and an isolation module 400 is located between the connection point of the electronic assembly 300 and the coil assembly 200 and the inner wall of the mounting space 110 to provide electrical isolation, preventing tip discharge at the connection point from causing ablation of the inner wall of the mounting space 110 of the yoke assembly 100. Please refer to [link to relevant documentation]. Figure 1 In one embodiment, the relay further includes a housing 500, and the yoke assembly 100, coil assembly 200, electronic assembly 300, and isolation module 400 are all disposed within the housing 500.

[0082] Please see Figures 2 to 5 In one embodiment, the partition module 400 includes a first partition 410 and a second partition 420. The yoke assembly 100 has adjacent first inner walls 111 and second inner walls 112. The first partition 410 is located between the connection between the electronic assembly 300 and the coil assembly 200 and the first inner wall 111, and the second partition 420 is located between the connection between the electronic assembly 300 and the coil assembly 200 and the second inner wall 112.

[0083] The first partition 410 can isolate the connection point from the first inner wall 111 of the yoke assembly 100, and the second partition 420 can isolate the connection point from the second inner wall 112 of the yoke assembly 100, thereby ensuring the isolation effect of the partition module 400 between the connection point and the yoke assembly 100.

[0084] For illustrative purposes, the first inner wall 111 and the second inner wall 112 are two adjacent inner walls in the mounting space 110 of the yoke assembly 100. For example, the first inner wall 111 may be the bottom wall of the mounting space 110 of the yoke assembly 100, and the second inner wall 112 may be a side wall of the mounting space 110 of the yoke assembly 100. Figure 2 In the embodiment shown, the first inner wall 111 is the top wall of the mounting space 110 of the yoke assembly 100, and the second inner wall 112 is the side wall of the mounting space 110 of the yoke assembly 100.

[0085] In one embodiment, the yoke assembly 100 includes a U-shaped yoke 120 and a yoke plate 130. The opposite ends of the yoke plate 130 are disposed at the opening of the U-shaped yoke 120 to form a cavity, thereby forming an installation space 110. The first inner wall 111 is the side wall of the yoke plate 130 near the installation space 110, and the second inner wall 112 is the inner side wall of one side of the U-shaped yoke 120.

[0086] Understandably, in other embodiments, the first inner wall 111 is the bottom wall of the U-shaped yoke 120, and the second inner wall 112 is the inner wall of one side of the U-shaped yoke 120.

[0087] Please see Figure 2 In one embodiment, the direction of the connection between the electronic component 300 and the coil component 200 toward the yoke component 100 is defined as the first direction, and the projections of the connection between the electronic component 300 and the coil component 200, the isolation module 400, and the yoke component 100 along the first direction at least partially overlap.

[0088] This configuration effectively isolates the connection between the electronic component 300 and the coil component 200, as well as between the yoke component 100, thus preventing voltage breakdown.

[0089] For illustrative purposes, the direction (i.e., the first direction) of the connection between the electronic component 300 and the coil component 200 (hereinafter referred to as the connection) toward the yoke component 100 can be the direction of the connection toward the first inner wall 111, the direction of the connection toward the second inner wall 112, or the connection toward the junction of the first inner wall 111 and the second inner wall 112.

[0090] In one embodiment, the direction of the connection between the electronic component 300 and the coil component 200 toward the first inner wall 111 is defined as the first direction, and the projections of the connection between the electronic component 300 and the coil component 200, the first partition 410, and the first inner wall 111 along the first direction at least partially overlap.

[0091] In one embodiment, the direction of the connection between the electronic component 300 and the coil component 200 toward the second inner wall 112 is defined as the first direction, and the projections of the connection between the electronic component 300 and the coil component 200, the second partition 420, and the second inner wall 112 along the first direction at least partially overlap.

[0092] In one embodiment, the first partition 410 and the second partition 420 are integrally formed, which not only facilitates processing but also improves the overall strength of the partition module 400.

[0093] As an embodiment that can be implemented alone or simultaneously with the above embodiments, the first partition 410 and the second partition 420 are arranged at an angle to match the angled first inner wall and the second inner wall of the yoke assembly, thereby ensuring the partition effect.

[0094] In one embodiment, the first partition 410 includes a first partition plate, the second partition 420 includes a second partition plate, and one end of the first partition plate is connected to one end of the second partition plate.

[0095] Furthermore, the plane containing the first partition is parallel to the plane containing the first inner wall 111, and the plane containing the second partition is parallel to the plane containing the second inner wall 112.

[0096] In one embodiment, the first partition and the second partition are arranged at an angle, and the connection between the coil assembly 200 and the electronic assembly 300 is located near the junction of the first partition and the second partition to ensure the separation effect of the first partition and the second partition.

[0097] Furthermore, the first partition and the second partition are perpendicular to each other.

[0098] Please see Figure 6 In one embodiment, the coil assembly 200 includes a coil frame, which includes a flange 210, a winding portion 220, and a pin 230. The flange 210 is disposed at one axial end of the winding portion 220, and the pin 230 is disposed on the flange 210 and electrically connected to the electronic assembly 300. The side of the flange 210 away from the winding portion 220 is disposed towards the first inner wall 111 and connected to the first partition 410.

[0099] A flange 210 is provided on the winding portion 220, and the side of the flange 210 away from the winding portion 220 is provided facing the first inner wall 111 of the yoke assembly 100. A first partition 410 is provided on the flange 210 to isolate the connection between the pin 230 and the electronic component 300 and the first inner wall 111 of the yoke assembly 100. The connection between the first partition 410 and the platform of the flange 210 ensures the installation reliability of the partition module 400.

[0100] Furthermore, the coil assembly 200 also includes a coil body 240, which is wound around the winding portion 220. One end of the pin 230 is located on the flange 210 and electrically connected to the coil body 240, thereby realizing the electrical connection between the electronic component 300 and the coil body 240.

[0101] Optionally, the flange 210 can be provided at either end of the winding portion 220, or the flange 210 can be provided at both ends of the winding portion 220. No specific limitation is made here.

[0102] exist Figure 6In the embodiment shown, two flanges 210 are provided and respectively disposed at opposite ends of the winding portion 220, thereby playing a certain limiting role on the coil body 240.

[0103] Please see Figure 7 In one embodiment, the electronic component 300 has a first through hole 311, and one end of the pin 230 away from the flange 210 extends toward the second partition 420 and through the first through hole 311.

[0104] One end of pin 230 passes through the first through hole 311 of electronic component 300 to achieve electrical connection with electronic component 300, and the connection effect is reliable.

[0105] In one embodiment, the electronic component 300 includes a circuit board 310 having a first through hole 311.

[0106] Furthermore, one end of pin 230 passing through the first through hole 311 is soldered to circuit board 310 to ensure the electrical connection effect and connection strength between circuit board 310 and pin 230.

[0107] Please see Figure 2 , Figure 6 and Figure 7 In one embodiment, pin 230 is disposed on the side wall of flange 210. The extension direction of pin 230 is parallel to the first inner wall 111 and perpendicular to the second inner wall 112. The plane where circuit board 310 is located is perpendicular to the first inner wall 111 and parallel to the second inner wall 112. The first through hole 311 is located at the edge of circuit board 310. Thus, when pin 230 passes through the first through hole 311 of circuit board 310, the edge of circuit board 310 is hung on the side wall of flange 210 by pin 230, resulting in a compact structure and improved space utilization inside the relay.

[0108] Furthermore, at least two pins 230 are provided, and at least two first through holes 311 are provided and are configured to correspond one-to-one with the pins 230. At least two pins 230 are connected to the circuit board 310, which can not only be used to implement different functions, but also improve the connection strength between the circuit board 310 and the pins 230.

[0109] Please see Figure 8 In one embodiment, the partition module 400 further includes a first partition rib 430, which is disposed on the side of the second partition member 420 facing away from the second inner wall 112. The first partition rib 430, the second partition member 420 and the first partition member 410 surround to form a receiving groove 431, which is connected to the first through hole 311. One end of the pin 230 away from the flange 210 is located in the receiving groove 431.

[0110] One end of pin 230 away from flange 210 passes through first through hole 311 and is located in receiving groove 431. Receiving groove 431 can provide more reliable isolation and insulation for the connection between pin 230 and circuit board 310, preventing discharge phenomenon at the connection between pin 230 and circuit board 310 from affecting yoke assembly 100.

[0111] In addition, the end of the first partition rib 430 is connected to the first partition member 410, which can improve the connection strength between the first partition member 410 and the second partition member 420 and prevent deformation between the first partition member 410 and the second partition member 420 from affecting the partition effect.

[0112] Understandably, in other feasible embodiments, the first partition 430 also separately encloses the receiving groove 431 on one side of the second partition 420, that is, the second partition 420 serves as the bottom wall of the receiving groove 431, and the first partition 430 is connected end to end to form the side wall of the receiving groove 431, which will not be described in detail here.

[0113] Furthermore, the arrangement of the receiving groove 431 can provide a more reliable isolation effect for the pin 230, preventing the tip discharge phenomenon at the pin 230 from affecting other components of the deyoke assembly 100.

[0114] Please see Figure 8 In one embodiment, the partition module 400 further includes at least one second partition rib 440, which is disposed in the receiving groove 431 and divides the receiving groove 431 to form at least two receiving spaces 441. At least two pins 230 and one through hole 311 are provided and are arranged in a one-to-one correspondence. All pins 230 are arranged in a one-to-one correspondence with the receiving spaces 441.

[0115] The second partition rib 440 provided in the receiving groove 431 can divide the receiving groove 431 into at least two receiving spaces 441. The at least two receiving spaces 441 can accommodate at least two pins 230 away from the flange 210 in a corresponding manner, so as to avoid mutual interference between the connection between each pin 230 and the circuit board 310, and further improve the isolation effect of the isolation module 400.

[0116] In addition, the second partition rib 440 can also strengthen the overall strength of the partition module 400 and improve the reliability of the partition module 400.

[0117] Please see Figure 8 In one embodiment, one end of the second partition rib 440 is connected to the first partition rib 430, and the other end of the second partition rib 440 is connected to the first partition member 410, thereby providing a certain support effect for the first partition member 410 and improving the connection strength between the second partition member 420 and the first partition member 410.

[0118] Please see Figure 8 In one embodiment, the partition module 400 further includes a third partition rib 450, which is disposed on the side of the second partition member 420 facing away from the second inner wall 112. The third partition rib 450, the second partition member 420 and the first partition rib 430 surround to form a dispensing groove 451. The groove opening of the dispensing groove 451 is disposed facing the electronic component 300 and is used to accommodate the fixing adhesive. The second partition member 420 is connected to the electronic component 300 through the fixing adhesive.

[0119] The adhesive in the dispensing groove 451 can fix the electronic component 300 to achieve the connection between the electronic component 300 and the second partition 420, and prevent the electrical connection from failing due to concentrated force at the connection between the electronic component 300 and the pin 230.

[0120] Understandably, the third partition rib 450 can not only form a dotting groove 451 with the second partition rib 420 and the first partition rib 430, but also strengthen the second partition rib 420 to a certain extent.

[0121] Further, please refer to Figure 8 The third dividing rib 450 includes a first rib 453, a second rib 454, and a third rib 455. The first rib 453, the second rib 454, the third rib 455, and the first dividing rib 430 are arranged to form a dotting groove 451.

[0122] Please see Figure 9 In one embodiment, the second partition 420 is further provided with a dispensing port 452, which is connected to the dispensing groove 451.

[0123] This configuration allows for the addition of fixing adhesive to the dispensing groove 451 via the dispensing port 452, simplifying the implementation and improving the overall assembly efficiency of the relay.

[0124] Please see Figures 7 to 8 In one embodiment, the second partition 420 is provided with a first positioning protrusion 421, and the electronic component 300 is provided with a first positioning hole 312, and the first positioning protrusion 421 is inserted into the first positioning hole 312.

[0125] The first positioning protrusion 421 on the second partition 420 can be inserted into the first positioning hole 312 on the electronic component 300 to achieve positioning between the second partition 420 and the electronic component 300. This not only prevents electrical connection failure due to force concentration at the connection between the electronic component 300 and the pin 230, but also provides auxiliary positioning for the electronic component 300 before adding fixing adhesive to the dispensing groove 451 through the dispensing port 452, preventing displacement of the electronic component 300 during the process of adding fixing adhesive to the dispensing groove 451, which would affect the fixing effect of the fixing adhesive.

[0126] Furthermore, the first positioning protrusion 421 is provided on the third partition rib 450, which can improve the strength of the first positioning protrusion 421 to a certain extent.

[0127] Please see Figures 7 to 8 In one embodiment, at least two first positioning protrusions 421 are provided and spaced apart, and at least two first positioning holes 312 are provided and are provided in a one-to-one correspondence with the first positioning protrusions 421.

[0128] As an embodiment that can be implemented alone or simultaneously with the above embodiments, the second partition 420 is provided with a second positioning hole, and the electronic component 300 is provided with a second positioning protrusion, which is inserted into the second positioning hole.

[0129] The second positioning hole and the second positioning protrusion are similar to the first positioning protrusion 421 and the first positioning hole 312, and will not be described again here.

[0130] Please see Figures 6 to 7 In one embodiment, the flange 210 is provided with a third positioning protrusion 212, and the electronic component 300 is provided with a third positioning hole 313. The third positioning protrusion 212 is inserted into the third positioning hole 313 to achieve positioning of the electronic component 300.

[0131] Furthermore, the third positioning protrusion 212 is located between two adjacent pins 230.

[0132] Furthermore, the third positioning hole 313 is a slot, which improves the ease of installation while ensuring the positioning effect.

[0133] Please see Figures 5 to 6 In one embodiment, the flange has a positioning groove 211, and at least a portion of the first partition 410 is disposed in the positioning groove 211 and is positioned and engaged with the positioning groove 211.

[0134] The positioning groove 211 on the table can engage with at least part of the positioning of the first partition 410 to prevent the first partition 410 from moving relative to the table and causing the position of the partition module 400 to change, thus ensuring the reliability of the partition effect of the partition module 400.

[0135] Furthermore, the shape of the positioning groove 211 matches the shape of at least a portion of the first partition 410 to ensure that at least a portion of the first partition 410 can be positioned and engaged with the positioning groove 211.

[0136] Please see Figures 5 to 6In one embodiment, the outer periphery of the first partition 410 is provided with a positioning protrusion 411, and correspondingly, the side wall of the positioning groove 211 is provided with a positioning recess 2111 that matches the positioning protrusion 411. In this way, when the first partition 410 is positioned and engaged with the positioning groove 211, the positioning protrusion 411 can also match the positioning recess 2111 to prevent the first partition 410 from detaching from the platform of the flange 210.

[0137] Furthermore, at least a portion of the first partition 410 is disposed within the positioning groove 211, and the first inner wall 111 of the yoke assembly 100 can abut against the first partition 410, thereby pressing the first partition 410 between the first inner wall 111 and the bottom wall of the positioning groove 211, ensuring the installation reliability of the first partition 410.

[0138] Please see Figure 2 and Figure 9 In one embodiment, the first partition 410 has an abutting protrusion 413 on the side facing the first inner wall 111, and the abutting protrusion 413 abuts against the first inner wall 111.

[0139] To improve the internal space utilization of the relay, the first inner wall 111 of the yoke assembly 100 needs to fit against the side of the first partition 410 facing the first inner wall 111. However, due to the tolerances between the various parts, as the first inner wall 111 and the first partition 410 gradually approach each other, the tolerances between the first inner wall 111 and the partition 410 can cause the first inner wall 111 to fail to fit against the first partition 410, resulting in an uneven yoke assembly 100 and affecting the assembly effect of the relay. By providing an abutment protrusion 413 on the side of the first partition 410 facing the first inner wall 111, as the first inner wall 111 and the first partition 410 gradually approach each other, the abutment protrusion 413 on the first partition 410 can abut against the first inner wall 111 and be squeezed and deformed by the first inner wall 111, thereby avoiding the unevenness of the yoke assembly 100 caused by the tolerances between the parts and ensuring the assembly effect.

[0140] Furthermore, at least two abutment protrusions 413 are provided and spaced apart on the side of the first partition 410 facing the first inner wall 111 to ensure the assembly effect.

[0141] Please see Figure 9 In one embodiment, the first partition 410 has a first groove 412.

[0142] The first groove 412 can reduce the weight of the first partition 410 while releasing structural stress and preventing the first partition 410 from deforming.

[0143] Furthermore, at least two first grooves 412 are provided, and all the first grooves 412 are arranged in parallel and spaced apart from the first partition member 410.

[0144] Furthermore, one end of the first groove 412 extends to the joint between the first partition 410 and the second partition 420 to improve the connection strength between the first partition 410 and the second partition 420 and prevent deformation between the first partition 410 and the second partition 420.

[0145] As an embodiment that can be implemented alone or simultaneously with the above embodiments, the second partition 420 has a second groove.

[0146] The second groove can reduce the weight of the second partition 420 while releasing structural stress and preventing deformation of the second partition 420.

[0147] The second groove is similar to the first groove 412, and will not be described again here.

[0148] Please see Figures 10 to 14 , Figures 10 to 14 A relay is shown in another embodiment of this application, and... Figures 1 to 9 Compared to the relays shown, Figures 10 to 14 The second isolation component 400 of the relay isolation module 400 is smaller in size, and thus has a lower manufacturing cost.

[0149] In one embodiment, the electronic component includes a circuit board 310, and a second partition 420 is located between the circuit board 310 and the yoke assembly 100.

[0150] As an embodiment that can be implemented alone or simultaneously with the above embodiments, the electronic component 300 includes a circuit board 310 and electronic components. The circuit board 310 is electrically connected to the coil assembly 200. The electronic components are disposed on the side of the circuit board 310 facing away from the coil assembly 200. The second partition 420 is also located between the electronic components and the yoke assembly 100.

[0151] The second partition 420 is located not only between the connection between the circuit board 310 and the coil assembly 200 and the yoke assembly 100, but also between the electronic components and the yoke assembly 100, to ensure the isolation effect between the electronic components and the yoke assembly 100.

[0152] As an embodiment that can be implemented alone or simultaneously with the above embodiments, the electronic component 300 includes a circuit board 310 and electronic components. The circuit board 310 is electrically connected to the coil assembly 200, and the electronic components are disposed on the side of the circuit board 310 facing the coil assembly 200.

[0153] The electronic components are disposed on the side of the circuit board 310 facing the coil assembly 200, away from the second inner wall 112 of the yoke assembly 100, thereby preventing the electronic components from discharging and damaging the yoke assembly 100. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0154] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
