Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a relay. Background Art

[0002] A relay is an electronic control device that uses one or more input signals (usually electrical signals) to control the state of one or more output circuits, achieving automatic circuit switching. The relay's main function is to isolate the control circuit from the controlled circuit, enabling low voltage and low current to control high voltage and high current.

[0003] Traditional relay armature motion methods typically include linear and snap-action electromagnets. Linear electromagnets typically offer a longer stroke, suitable for applications requiring a wide range of motion. Snap-action electromagnets have a shorter stroke because they are designed primarily for rapid closing and opening, rather than long-distance movement. Existing snap-action electromagnet relays, due to the limited range of motion of their moving contacts, make it difficult to reduce the distance from the moving contact to the stationary contact, often preventing miniaturization.

[0031] The present invention provides a relay 100 .

[0032] See also Figures 1 to 3 In one embodiment of the present invention, the relay 100 includes: a base 1, a yoke 2, an electromagnet 3, a static terminal portion 4 and a dynamic terminal portion 5, the yoke 2 is connected to the base 1; the electromagnet 3 is connected to the yoke 2; the static terminal portion 4 is connected to the base 1, and the static terminal portion 4 is provided with a static contact 41. The static terminal portion 4 is located on one side of the electromagnet 3 and is used to electrically connect to an external circuit; the dynamic terminal portion 5 is movably provided on the base 1, and the dynamic terminal portion 5 includes an armature 51, a contact seat 52 and a dynamic contact 53. The armature 51 is rotatably connected to the yoke 2. The armature 51 is located at the end of the electromagnet 3 away from the base 1, the contact seat 52 is rotatably connected to the armature 51, the contact seat 52 is slidably connected to the base 1, the contact seat 52 is located between the yoke 2 and the static terminal part 4, and the moving contact 53 is located at the end of the contact seat 52 close to the static terminal part 4; wherein, the electromagnet 3 is used to drive the armature 51 to rotate so that the moving contact 53 abuts or disengages from the static contact 41; a clearance channel 51a is provided on the armature 51, and when the moving contact 53 abuts the static contact 41, the clearance channel 51a can accommodate at least part of the contact seat 52.

[0033] In an embodiment of the present invention, the yoke 2 is connected to the base 1 by bolts, welding, or direct casting, ensuring structural stability and durability. The electromagnet 3, through its core portion, tightly fits the corresponding ends of the yoke 2, typically using an interference fit or threaded connection to ensure stable positioning of the electromagnet 3 on the yoke 2. The static terminal portion 4 is connected to the base 1 by welding or plugging, and is designed to be positioned on one side of the electromagnet 3 to facilitate electrical connection with the external circuit. The static terminal portion 4 is internally provided with static contacts 41, which are typically made of highly conductive and wear-resistant materials such as copper or copper alloy to ensure good electrical contact performance. The position of the static terminal portion 4 is reliably fixed, ensuring that the contact between the static contact 41 and the moving contact 53 accurately corresponds during the opening and closing operation of the relay 100, achieving reliable circuit switching. This structural design makes the connections between the various components of the relay 100 both firm and flexible, making it easy to assemble and maintain. The connection method between the yoke 2 and the base 1 ensures the stability of the electromagnet 3 during operation and reduces the risk of damage due to vibration or impact. The close fit between electromagnet 3 and yoke 2 ensures effective electromagnetic force transmission, improving the response speed and reliability of relay 100. The connection between static terminal 4 and base 1 simplifies the external circuit connection process. The material selection and positioning design of static contact 41 optimize electrical contact performance, reducing contact resistance and oxidation risk, thereby extending the service life of relay 100 and improving its stability and reliability in various environments.

[0034] It should be noted that in the design of this relay 100, the movable terminal portion 5 is designed to be movably mounted on the base 1. The movable terminal portion 5 includes three main parts: an armature 51, a contact seat 52, and a movable contact 53. The armature 51 and the yoke 2 are rotatably connected via a hole-shaft fit or a hinge structure, ensuring that the armature 51 can flexibly rotate under the action of the electromagnet 3. The armature 51 is located at the end of the electromagnet 3 away from the base 1 so that it can move under the drive of the electromagnet 3. The contact seat 52 and the armature 51 are also connected by a similar rotational connection method. At the same time, the contact seat 52 and the base 1 are slidably connected via a guide rail and slider, such as a guide rail and slider structure, to achieve precise relative movement. The contact seat 52 is designed to be positioned between the yoke 2 and the static terminal portion 4, while the movable contact 53 is located at the end of the contact seat 52 closer to the static terminal portion 4 so that it can contact the static contact 41. The function of the electromagnet 3 is to drive the armature 51 to rotate, thereby driving the contact 53 seat 52 to move, so that the moving contact 53 and the static contact 41 are in contact or disengaged. The armature 51 is specially designed with a clearance channel 51a. When the moving contact 53 contacts the static contact 41, the clearance channel 51a can accommodate at least part of the contact seat 52 to reduce space occupancy and achieve miniaturization of the relay 100. This design enables the relay 100 to achieve fast and accurate contact contact during operation, thereby improving the response speed and reliability of the relay 100. The rotational connection between the armature 51 and the contact seat 52 and the sliding connection between the contact seat 52 and the base 1 ensure that the contact between the moving contact 53 and the static contact 41 is stable and consistent, reducing the risk of poor contact. The design of the clearance channel 51a allows the relay 100 to be miniaturized without sacrificing the contact area or reliability of the contacts, which is particularly important for high-density installation environments. In addition, this structural design also helps to reduce mechanical wear of the relay 100 during operation, extending the service life of the product, while also reducing manufacturing costs because it reduces the required materials and space.

[0035] The technical solution of the present utility model is to design a relay 100, which includes a base 1, a yoke 2, an electromagnet 3, a static terminal portion 4, and a moving terminal portion 5. The yoke 2 connects the electromagnet 3 and the base 1, and the static terminal portion 4 is connected to the base 1 and is provided with a static contact 41. The static terminal portion 4 is located on one side of the electromagnet 3 and is used to electrically connect to an external circuit. The moving terminal portion 5 is movably arranged on the base 1 and includes an armature 51, a contact seat 52, and a moving contact 53. The armature 51 is rotatably connected to the yoke 2 and is located at the end of the electromagnet 3 away from the base 1; the contact seat 52 is rotatably connected to the armature 51, slidably connected to the base 1, and is located between the yoke 2 and the static terminal portion 4; the moving contact 53 is located at the end of the contact seat 52 close to the static terminal portion 4. The electromagnet 3 drives the armature 51 to rotate, causing the moving contact 53 to abut or disengage with the static contact 41. The armature 51 is provided with a clearance channel 51a. When the moving contact 53 abuts the static contact 41, the clearance channel 51a can accommodate at least part of the contact seat 52, thereby achieving a miniaturized design. Through the above-mentioned structural design, the relay 100 achieves miniaturization and fast response. The design of the clearance channel 51a on the armature 51 allows the contact seat 52 to be partially stored inside the armature 51 when the moving contact 53 contacts the static contact 41, thereby reducing the distance of the relay 100 along the direction from the moving contact 53 to the static contact 41, thereby achieving miniaturization of the relay 100. At the same time, due to the rotational and sliding connection between the armature 51 and the contact seat 52, the operation of the relay 100 is more flexible and the response speed is faster, thereby improving the operating performance and reliability of the relay 100. This design not only saves space but also facilitates application in high-density installation environments while maintaining the stability and reliability of the electrical connection.

[0036] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 The armature 51 has a first bending section 511 and a second bending section 512 , the first bending section 511 is rotatably connected to the yoke 2 , the first bending section 511 is located at the end of the electromagnet 3 away from the base 1 , and the second bending section 512 is rotatably connected to the contact seat 52 .

[0037] In one embodiment, the armature 51 is designed to have a first bent section 511 and a second bent section 512. The first bent section 511 is rotatably connected to the yoke 2 via a hole-shaft fit or a hinge structure. This connection allows the armature 51 to flexibly rotate under the action of the electromagnet 3 while maintaining its connection to the yoke 2. The first bent section 511 is located at the end of the electromagnet 3 away from the base 1. This layout helps the armature 51 generate sufficient torque under the drive of the electromagnet 3, achieving rapid opening and closing of the contacts. The second bent section 512 is rotatably connected to the contact seat 52, allowing the contact seat 52 to slide as the armature 51 rotates, thereby controlling the contact state between the movable contact 53 and the static contact 41. The contact seat 52 and the base 1 utilize a sliding connection, such as a guide rail and slider structure, to achieve precise relative motion, ensuring that the contact seat 52 can move smoothly between the yoke 2 and the static terminal portion 4. This design of the armature 51 provides a compact and effective mechanism for rapid and precise control of the contacts of the relay 100. Through the design of the first bend section 511 and the second bend section 512, the relay 100 can achieve flexible movement of the armature 51, thereby quickly responding to the drive of the electromagnet 3 and improving the switching speed of the relay 100. At the same time, the design of the yield channel 51a allows the relay 100 to be miniaturized while maintaining performance, which is particularly important in space-constrained applications.

[0038] In one embodiment of the present invention, please refer to Figure 4 The armature 51 further includes a protective layer 513 , which is sleeved on the second bending section 512 and is made of insulating material.

[0039] In this embodiment, a protective layer 513 is provided on the second bending section 512. The protective layer 513 is made of an insulating material, such as polyimide, phenyl silicone rubber or polysilazane. The protective layer 513 is sleeved on the second bending section 512 to provide electrical isolation and physical protection. The function of the protective layer 513 is to ensure that the contact seat 52 is fully protected during the movement of the armature 51 to avoid electrical short circuits or mechanical damage. The use of the protective layer 513 not only enhances the insulation performance of the relay 100, but also improves its durability and reliability in complex environments. The use of the insulating protective layer 513 can prevent electrical failures caused by environmental pollution or humidity, while also reducing electromagnetic interference and improving the stability and safety of the relay 100. In addition, the protective layer 513 can also protect the armature 51 and the contact seat 52 from physical damage, extend the service life of the relay 100, and may reduce maintenance costs.

[0040] In one embodiment of the present invention, please refer to Figure 2 and Figure 3The relay 100 further includes a reset elastic member 6 , two ends of which are respectively connected to the first bending section 511 and the yoke 2 .

[0041] In one embodiment, the reset spring 6 is a key component for resetting the armature 51. Its two ends connect the first bend section 511 and the yoke 2, respectively, to achieve the reset function of the armature 51. The reset spring 6 is typically made of a spring material, such as stainless steel spring wire or a highly elastic polymer material, to provide a stable reset force. One end of the reset spring 6 is connected to the first bend section 511 by welding, bolting, or a dedicated fixing fixture; the other end is connected to a fixing hole or slot in the yoke 2. The reset spring 6 is positioned so as to span between the first bend section 511 and the yoke 2, ensuring that the armature 51, after moving under the suction force of the electromagnet 3, can be quickly and accurately reset to its initial state when power is removed. The use of the reset spring 6 significantly improves the response speed and reliability of the relay 100. When the coil of the electromagnet 3 is de-energized, the elastic force of the reset spring 6 can quickly pull the armature 51 back, causing the movable contact 53 to quickly separate from the static contact 41, reducing arcing, preventing contact adhesion, and extending the service life of the contacts. Furthermore, the design of the resetting spring 6 helps reduce the power consumption of the relay 100 because it can quickly reset the armature 51, reducing the additional energy consumption caused by the armature 51 remaining in the energized state. This design also improves the mechanical and electrical stability of the relay 100, enabling it to operate stably under various environmental conditions.

[0042] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 A first connecting portion 514 is provided on the armature 51, and a second connecting portion 21 is provided on the yoke 2. The first connecting portion 514 is located in the give way channel 51a, and the second connecting portion 21 is located at the end of the yoke 2 facing away from the electromagnet 3. The two ends of the reset elastic member 6 are respectively connected to the first connecting portion 514 and the second connecting portion 21.

[0043] In this embodiment, the armature 51 is designed to include a first connecting portion 514, and a second connecting portion 21 is provided on the yoke 2. The first connecting portion 514 is located at the give way channel 51a on the armature 51, and the second connecting portion 21 is located at the end of the yoke 2 facing away from the electromagnet 3. This is to facilitate the elastic reset member to better connect the armature 51 and the yoke 2, and to help reset the armature 51 through the pulling force of the reset elastic member 6 when the electromagnet 3 is not working, thereby realizing the miniaturization design of the relay 100. This design enables the relay 100 to achieve fast and accurate contact contact during operation, thereby improving the response speed and reliability of the relay 100. The provision of the first connecting portion 514 and the second connecting portion 21, in conjunction with the use of the reset elastic member 6, ensures that the armature 51 can be quickly and accurately reset to the initial state after the electromagnet 3 is powered off, reduces arc generation, avoids contact adhesion, and extends the service life of the contacts. Furthermore, this design helps reduce the power consumption of the relay 100 because it can quickly reset the armature 51, reducing the additional energy consumption caused by the armature 51 remaining in the energized state. Furthermore, this design improves the mechanical and electrical stability of the relay 100, enabling it to operate stably under various environmental conditions.

[0044] In one embodiment of the present invention, please refer to Figure 5 and Figure 6 The contact seat 52 is provided with a sliding groove 52a, which extends along the movement direction of the moving contact 53. The sliding groove 52a is located at one end of the contact seat 52 close to the base 1. The base 1 is provided with a sliding boss 11 that slides with the contact seat 52.

[0045] In one embodiment, the contact seat 52 is specifically provided with a sliding groove 52a, which extends along the direction of movement of the movable contact 53 to ensure that the contact seat 52 can move smoothly along the predetermined path. The sliding groove 52a is located at the end of the contact seat 52 close to the base 1. The base 1 is provided with a sliding boss 11 that slides with the contact seat 52. The sliding boss 11 matches the sliding groove 52a on the contact seat 52 to provide precise guidance and positioning. The sliding boss 11 may be formed by injection molding or machining and is made of the same material as the base 1, such as plastic or metal, to ensure wear resistance and stability during sliding. The positional relationship of the sliding boss 11 is precisely corresponding to the sliding groove 52a, ensuring that the contact seat 52 does not deviate from the predetermined trajectory during movement. The connection method may include direct mechanical fit or the use of a guide rail and slider structure to achieve smooth and precise sliding movement. This design provides a reliable sliding mechanism, ensuring precise movement of the contact holder 52 during operation of the relay 100, thereby improving contact reliability and the overall performance of the relay 100. The coordinated use of the sliding groove 52a and the sliding boss 11 reduces friction and wear, extending the service life of the contact holder 52 and the base 1. Furthermore, this precise sliding fit helps reduce contact errors between the contacts and improves the switching accuracy of the relay 100, which is particularly important in applications requiring high reliability and precise control.

[0046] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The movable terminal portion 5 includes a contact platform 54 , and the movable contact 53 is connected to the contact platform 54 and is located on a side of the contact platform 54 facing the static terminal portion 4 .

[0047] In this embodiment, the movable terminal portion 5 is designed to include a contact plate 54. The movable contact 53 is connected to the contact plate 54 via welding, riveting, or plug-in connection; alternatively, the movable contact 53 and the contact plate 54 are designed and manufactured as a unified, integrated structure, ensuring the stability and reliability of the movable contact 53 during operation of the relay 100. The movable contact 53 is positioned on the side of the contact plate 54 facing the static terminal portion 4. This layout enables the movable contact 53 to directly contact the static contact 41 to connect or disconnect the circuit. The contact plate 54 and the movable contact 53 are typically constructed of materials with good electrical conductivity and wear resistance, such as copper or copper alloys, to ensure long-term electrical connection performance and durability. This design ensures more precise and reliable contact between the movable contact 53 and the static contact 41 of the relay 100, improving the switching performance of the relay 100. The design of the contact plate 54 provides stable support for the movable contact 53, reducing the risk of circuit failure due to poor contact or wear. In addition, the positional relationship of the contact platform 54 makes the contact between the movable contact 53 and the static contact 41 more direct, thereby reducing contact resistance and improving current transmission efficiency.

[0048] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 A contact channel 52b is provided on the contact seat 52, and a contact platform 54 is connected to the inner wall of the contact channel 52b. Both ends of the contact platform 54 extend out of the contact channel 52b, and both ends of the contact platform 54 are connected to a moving contact 53 respectively.

[0049] In one embodiment, the contact base 52 is provided with a contact channel 52b extending along the direction of movement of the movable contact 53, allowing the movable contact to move within the contact channel 52b. The contact base 54 is connected to the inner wall of the contact channel 52b via a snap or bolt structure, ensuring the stability and durability of the contact base 54. Both ends of the contact base 54 extend out of the contact channel 52b, and a movable contact 53 is connected to each end of the contact base 54. This design allows the two movable contacts 53 to simultaneously engage or disengage with the two stationary contacts 41. The contact base 54 and movable contact 53 are typically made of highly conductive and wear-resistant materials, such as copper or copper alloys, to ensure long-term electrical connection performance and durability. The design of the contact channel 52b and contact base 54 on the contact base 52 enables the movable contact 53 to smoothly and accurately engage with the stationary contact 41, improving the switching accuracy and reliability of the relay 100. The contact platform 54, extending from the contact channel 52b, is connected to the movable contact 53 at both ends, ensuring a stable electrical connection between the contacts and reducing the risk of poor contact. Furthermore, this design, in which the bridge movable contact 53 is independently mounted on the contact base 52, ensures contact stability and reduces contact resistance, thereby lowering the temperature rise of the terminal and achieving miniaturization.

[0050] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The movable terminal portion 5 includes a contact spring 55, which connects the contact platform 54 and the contact seat 52. The contact spring 55 is located in the contact channel 52b.

[0051] In this embodiment, the movable terminal portion 5 includes a contact spring 55. The contact spring 55 is designed to connect the contact platform 54 to the contact holder 52, ensuring stable contact between the movable contact 53 and the stationary contact 41 during operation of the relay 100. The contact spring 55 is typically made of a material with excellent elasticity and conductivity, such as stainless steel or phosphor bronze wire, to ensure its elasticity and durability. The contact spring 55 is positioned within the contact channel 52b. This design allows the contact spring 55 to provide the necessary elastic force between the contact platform 54 and the contact holder 52, while maintaining its proper position within the contact channel 52b and avoiding interference with the channel walls. Two or more sets of bridge-type movable contacts 53 are independently mounted on the contact holder 52, each of which applies pressure to the contact platform 54. To maintain the position of the bridge-type contact platform 54, which holds the movable contacts 53, the contact spring 55 is installed between the movable contact platform 53 and the contact holder 52, elastically connecting them. The electrical continuity and reliability of relay 100 is improved by ensuring a low, stable resistance without minor discontinuities even when the piston moves or is exposed to strong shock and vibration.

[0052] In one embodiment of the present invention, please refer to Figures 1 to 3 The movable terminal portion 5 includes a plurality of contact platforms 54 and a plurality of movable contacts 53, and every two movable contacts 53 are connected to the two ends of a contact platform 54; the contact seat 52 is provided with a plurality of contact channels 52b corresponding to the contact platforms 54, and the movable terminal portion 5 includes a plurality of contact springs 55, and each contact spring 55 connects a contact platform 54 and the inner wall of a contact channel 52b.

[0053] In one embodiment, the movable terminal portion 5 integrates multiple contact platforms 54 and multiple movable contacts 53, with two movable contacts 53 connected to each end of a contact platform 54. The contact base 52 is designed with multiple contact channels 52b, which correspond one-to-one with the contact platforms 54, allowing the movable contact 53 of each contact platform 54 to move along its respective contact channel 52b. Furthermore, the movable terminal portion 5 includes multiple contact springs 55, each connecting a contact platform 54 to the inner wall of the corresponding contact channel 52b, ensuring proper pressure and contact between the movable contact 53 and the stationary contact 41. The contact platforms 54 and movable contacts 53 are typically made of conductive and wear-resistant materials, such as copper or copper alloys, while the contact springs 55 may be made of an elastic material such as stainless steel or phosphor bronze. The positional relationship between the contact platforms 54 and movable contacts 53 is precisely designed to ensure that the movable contact 53 accurately contacts the stationary contact 41, thereby connecting or disconnecting the circuit. This design provides a compact and responsive contact connection method, allowing the relay 100 to handle the connection and disconnection of multiple circuits at the same time, thereby improving the functionality and flexibility of the relay 100. By providing multiple contact channels 52b on the contact base 52, the relay 100 can realize the independent operation of multiple contacts within a limited space, saving space and improving efficiency. The use of the contact spring 55 ensures stable contact pressure between the moving contact 53 and the static contact 41, reduces the risk of poor contact, and improves the reliability and stability of the relay 100. In addition, this design also helps to reduce the contact resistance between the contacts and improve the current transmission efficiency, thereby improving the overall performance of the relay 100. By optimizing the structure of the contact base 54, the contact channel 52b and the contact spring 55, the miniaturization and integration of the relay 100 are improved, and the assembly efficiency and maintenance convenience are improved.

[0054] In one embodiment of the present invention, please refer to Figure 3 and Figure 7 The relay 100 further includes a housing 7 , which is provided with a fixed boss 71 . The fixed boss 71 extends along the moving direction of the movable contact 53 , and the contact seat 52 is provided with a groove 52 c that slides with the fixed boss 71 .

[0055] In this embodiment, the relay 100 further includes a housing 7, on which a fixed boss 71 is provided. The fixed boss 71 extends along the direction of movement of the moving contact 53 to ensure that the contact seat 52 can move smoothly along a predetermined path. The contact seat 52 is provided with grooves 52c that slide in conjunction with the fixed boss 71. These grooves 52c match the shape and size of the fixed boss 71, allowing the contact seat 52 to move smoothly within the housing 7. The connection between the fixed boss 71 and the groove 52c may include direct mechanical engagement, or the use of a guide rail and slider structure to achieve precise sliding movement. In terms of material, the fixed boss 71 and the groove 52c of the contact seat 52 can be made of the same material, such as plastic or metal, to ensure wear resistance and stability during sliding. In terms of positional relationship, the setting of the fixed boss 71 and the groove 52c must correspond precisely to ensure that the contact seat 52 does not deviate from the predetermined trajectory during movement. This design provides a reliable sliding mechanism, ensuring precise movement of the contact holder 52 during operation of the relay 100, thereby improving contact reliability and the overall performance of the relay 100. The coordinated use of the fixed boss 71 and the groove 52c reduces friction and wear, extending the service life of the contact holder 52 and the housing 7. Furthermore, this precise sliding fit helps reduce contact error between the contacts, improving the switching accuracy of the relay 100. By optimizing the structure of the fixed boss 71 and the groove 52c, the miniaturization and integration of the relay 100 are enhanced, while also reducing manufacturing costs, improving assembly efficiency, and facilitating maintenance.
