Description

Technical Field

[0001] This invention relates to the field of electrical component technology, and in particular to a relay and a relay assembly method. Background Technology

[0002] Relays, as important electrical control components, are widely used in industrial automation, automotive electronics, power systems, smart homes, and many other fields. Their core function is to control the opening and closing of main contacts by energizing and de-energizing an electromagnetic coil, thereby achieving circuit switching, signal transmission, and load control. Auxiliary contacts, as an important component of the relay, are mainly used to monitor the status of the main contacts and realize logic control such as circuit self-locking and interlocking. They are key components for ensuring the reliability of relay operation and expanding control functions. The current they carry is usually in the milliampere range, and their size is relatively small, but their structural design directly affects the overall assembly efficiency, size layout, and feasibility of automated production of the relay.

[0003] In existing relay products, the auxiliary contact terminals mostly adopt a through-hole structure. This design is a traditional structure that has been used in the industry for a long time, and its core advantage lies in its compatibility with the assembly process of auxiliary contact components. Through-hole auxiliary contact terminals usually precisely match the pre-set mounting holes on the relay base. During assembly, the terminals can be directly inserted into the corresponding holes to complete the fixation, without the need for complex positioning fixtures and connection procedures. This effectively simplifies the assembly process of auxiliary contact components, reduces assembly difficulty, and helps improve the stability of the connection between the auxiliary contacts and the base, reducing the occurrence of problems such as loose terminals and poor contact during assembly. It is suitable for the basic assembly needs in mass production, and is most widely used in small and medium-sized relay products. Some industrial-grade relays also use a similar through-hole design for the auxiliary contact leads, achieving fixation through mounting holes on the side wall of the base.

[0004] However, with the rapid development of industrial automation, new energy, and other fields, the market's performance requirements for relays are constantly upgrading, and the application scenarios of high-force relays are becoming increasingly widespread. High-force relays are mainly used to control high-power, high-current loads. To meet their suction requirements, larger electromagnetic coils are needed to generate sufficient electromagnetic force to drive the armature and thus reliably switch the main contacts on and off. Their coil assemblies typically include larger coils, magnetic conductors, etc., resulting in a more compact overall structure. At the same time, to ensure compatibility between the relay and external circuits, most high-force relays adopt a fixed pin layout design, meaning the positions of the coil terminals, main contact terminals, and auxiliary contact terminals are relatively fixed. This can easily cause interference with the electromagnetic coil during assembly, leading to assembly difficulties or even preventing automated assembly. Summary of the Invention

[0005] The main objective of this invention is to provide a relay that offers greater installation space for the coil assembly and reduces assembly difficulty.

[0006] To achieve the above objectives, the relay proposed in this invention includes a base, an auxiliary stationary terminal, an auxiliary moving terminal, and a coil assembly. The auxiliary stationary terminal includes a first pin and a first clearance section connected to each other, and the auxiliary moving terminal includes a second pin and a second clearance section connected to each other.

[0007] The first pin, the second pin, and the coil assembly are all connected to the base; The first clearance segment and the second clearance segment are arranged opposite to each other, and the distance between the first clearance segment and the second clearance segment is greater than the distance between the first pin and the second pin; The coil assembly is located between the first clearance section and the second clearance section.

[0008] In one embodiment, the auxiliary stationary terminal further includes a first bent section; One end of the first bending segment is connected to the first pin and is set at an angle to the first pin, and extends in a direction away from the auxiliary moving terminal. The other end of the first bending segment is connected to the first clearance segment and is set at an angle to the first clearance segment, and the first clearance segment extends in a direction away from the first pin.

[0009] In one embodiment, the auxiliary moving terminal further includes a second bent section; One end of the second bending section is connected to the second pin and is set at an angle to the second pin, and extends in a direction away from the auxiliary stationary terminal. The other end of the second bending section is connected to the second clearance section and is set at an angle to the second clearance section, and the second clearance section extends in a direction away from the second pin.

[0010] In one embodiment, the auxiliary stationary terminal further includes a third bent section, the auxiliary moving terminal further includes a fourth bent section, and the relay further includes an auxiliary stationary contact, an auxiliary moving contact, and an auxiliary moving spring. The third bending section is connected to the first clearance section and is set at an angle to the first clearance section, and extends from the first clearance section toward the auxiliary moving terminal; The fourth bending segment connects to the second clearance segment and is set at an angle to the second clearance segment, and extends from the second clearance segment toward the auxiliary stationary terminal. The auxiliary stationary contact is located in the third bending section; The auxiliary moving spring is located in the fourth bending section; The auxiliary moving contact is located on the auxiliary moving spring and contacts the auxiliary stationary contact.

[0011] In one embodiment, the coil assembly has two positioning holes, and both the third and fourth bending sections have positioning pins. The two positioning pins are respectively inserted into the two positioning holes for positioning.

[0012] In one embodiment, the auxiliary stationary terminal has a first pre-formed bend, which is connected to the first clearance section and the third bend section respectively. And / or, the auxiliary moving terminal is formed with a second pre-formed bend, the second pre-formed bend being connected to the second clearance section and the fourth bend section respectively.

[0013] In one embodiment, the relay further includes an actuating assembly, the actuating assembly including an armature and an actuating element; The armature is rotatably connected to the coil assembly; The pusher is connected to the armature and abuts against the auxiliary moving spring.

[0014] This invention also proposes a method for assembling a relay. The relay further includes an auxiliary stationary contact, an auxiliary moving contact, an auxiliary moving spring, an armature, and a pusher. The coil assembly has two positioning holes. The auxiliary stationary terminal further includes a third bent section, a positioning pin, and a first pre-formed bent portion. The auxiliary moving terminal further includes a fourth bent section, a positioning pin, and a second pre-formed bent portion. Before assembly, the first clearance section and the third bent section are arranged in the same direction, and the second clearance section and the fourth bent section are arranged in the same direction. The assembly method of the relay includes the following steps: The auxiliary stationary contact is installed onto the auxiliary stationary terminal to obtain the auxiliary stationary component; The auxiliary moving spring and the auxiliary moving contact are installed onto the auxiliary moving terminal to obtain the auxiliary moving assembly; The auxiliary static component, the auxiliary moving component, and the coil assembly are respectively installed on the base, with the coil assembly located between the auxiliary static component and the auxiliary moving component; The pusher is installed to the armature; and the armature is installed to the coil assembly; The fourth bending segment is bent, and the auxiliary moving spring abuts against the pushing member; The third bending section is bent, and the auxiliary stationary contact is brought into contact with the auxiliary moving contact to obtain the relay.

[0017] In the technical solution of this invention, the auxiliary stationary terminal is mounted to the base with its first pin, and the auxiliary moving terminal is mounted to the base with its second pin. Although the circuit board of the relay base limits the distance between the first pin and the second pin, the distance between the first clearance section and the second clearance section is greater than the distance between the first pin and the second pin. This provides a larger installation space for the coil assembly to be mounted between the first clearance section and the second clearance section than between the first pin and the second pin. This allows for a larger installation space for the coil assembly without changing the circuit board layout of the relay, thereby reducing the possibility of interference between the coil assembly and the auxiliary stationary terminal and the auxiliary moving terminal, reducing assembly difficulty, and providing greater operating space for the automated assembly of the relay.

[0025] This invention proposes a relay 100, Figures 1 to 5 This is one embodiment of the present invention.

[0026] In this embodiment of the invention, the relay 100 includes a base 1, an auxiliary stationary terminal 2, an auxiliary moving terminal 3, and a coil assembly 4. The auxiliary stationary terminal 2 includes a first pin 21 and a first clearance section 22 connected to each other. The auxiliary moving terminal 3 includes a second pin 31 and a second clearance section 32 connected to each other. The first pin 21, the second pin 31, and the coil assembly 4 are all connected to the base 1. The first clearance section 22 and the second clearance section 32 are arranged opposite to each other, and the distance between the first clearance section 22 and the second clearance section 32 is greater than the distance between the first pin 21 and the second pin 31.

[0027] In the technical solution of the present invention, the auxiliary stationary terminal 2 is mounted to the base 1 with its first pin 21, and the auxiliary moving terminal 3 is mounted to the base 1 with its second pin 31. Although the circuit board of the base 1 of the relay 100 limits the distance between the first pin 21 and the second pin 31, the distance between the first clearance section 22 and the second clearance section 32 is greater than the distance between the first pin 21 and the second pin 31. This provides a larger installation space for the coil assembly 4 between the first clearance section 22 and the second clearance section 32 than between the first pin 21 and the second pin 31. This allows for a larger installation space for the coil assembly 4 without changing the circuit board layout of the relay 100, thereby reducing the possibility of interference between the coil assembly 4 and the auxiliary stationary terminal 2 and the auxiliary moving terminal 3, reducing assembly difficulty, and providing a larger operating space for the automated assembly of the relay 100.

[0028] The coil assembly 4 includes a magnetic circuit structure such as a coil, a frame, and a yoke, and the armature 81 of the relay 100 is actually rotatably connected to the yoke. Figure 4 and Figure 5 The images shown are of the auxiliary stationary terminal 2 before and after bending at the third bending section 24. The auxiliary moving terminal 3 is bent in the same way as the auxiliary stationary terminal 2, which can be referred to below. Figure 4 and Figure 5 .

[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the second pin 31, the second bent section 33, the second clearance section 32, and the second pre-made bent portion 35 of the auxiliary moving terminal 3 correspond one-to-one with the first pin 21, the first bent section 23, the first clearance section 22, and the first pre-made bent portion 25 of the auxiliary stationary terminal 2. The difference between the fourth bent section 34 and the third bent section 24 is that the mounting structure for installing the auxiliary stationary contact 5 and the auxiliary moving spring 7 is different.

[0030] In one embodiment, such as Figure 4 and Figure 5As shown, the auxiliary stationary terminal 2 further includes a first bent section 23; one end of the first bent section 23 is connected to the first pin 21 and is set at an angle to the first pin 21, and extends in a direction away from the auxiliary moving terminal 3; the other end of the first bent section 23 is connected to the first clearance section 22 and is set at an angle to the first clearance section 22, and the first clearance section 22 extends in a direction away from the first pin 21. The first bent section 23 is at an angle to the first pin 21 and extends in a direction away from the auxiliary moving terminal 3, making the distance between the other end of the first bent section 23 and the auxiliary moving terminal 3 larger. The first clearance section 22 is connected to the first bent section 23, further expanding the distance between the first clearance section 22 and the auxiliary moving terminal 3, allowing a larger clearance space to be formed between the first clearance section 22 and the second clearance section 32, and further freeing up the installation space of the coil assembly 4. At the same time, the bending structure can improve the structural rigidity of the auxiliary stationary terminal 2, avoid terminal deformation, further reduce the interference risk between the coil assembly 4 and the auxiliary stationary terminal 2, and provide more sufficient operating space for automated assembly.

[0031] In one embodiment, such as Figure 4 and Figure 5 As shown, the first bent section 23 is perpendicular to the first pin 21, so that the length direction of the first bent section 23 is completely consistent with the direction away from the auxiliary moving terminal 3. This can maximize the distance between the first bent section 23 and the auxiliary moving terminal 3, further expand the installation space of the coil assembly 4, and reduce the risk of interference between the coil assembly 4 and the auxiliary stationary terminal 2.

[0032] In one embodiment, the auxiliary moving terminal 3 further includes a second bent section 33; one end of the second bent section 33 is connected to the second pin 31 and is set at an angle to the second pin 31, and extends in a direction away from the auxiliary stationary terminal 2; the other end of the second bent section 33 is connected to the second clearance section 32 and is set at an angle to the second clearance section 32, and the second clearance section 32 extends in a direction away from the second pin 31. The angle between the second bent section 33 and the second pin 31 and the extension in a direction away from the auxiliary moving terminal 3 increases the distance between the other end of the second bent section 33 and the auxiliary stationary terminal 2. The connection of the second clearance section 32 to the second bent section 33 further expands the distance between the second clearance section 32 and the auxiliary stationary terminal 2, allowing a larger clearance space to be formed between the first clearance section 22 and the second clearance section 32, and further freeing up the installation space of the coil assembly 4. At the same time, the bending structure can improve the structural rigidity of the auxiliary stationary terminal 2, avoid terminal deformation, further reduce the interference risk between the coil assembly 4 and the auxiliary moving terminal 3, and provide more sufficient operating space for automated assembly.

[0033] In one embodiment, the second bent section 33 is arranged perpendicular to the second pin 31 to further expand the installation space of the coil assembly 4.

[0034] In one embodiment, the auxiliary stationary terminal 2 has a first bending section 23 and the auxiliary moving terminal 3 has a second bending section 33. The combined effect of the two provides a larger installation space for the coil assembly 4.

[0035] In one embodiment, such as Figure 4 and Figure 5 As shown, the auxiliary stationary terminal 2 further includes a third bending section 24, the auxiliary moving terminal 3 further includes a fourth bending section 34, and the relay 100 further includes an auxiliary stationary contact 5, an auxiliary moving contact 6, and an auxiliary moving spring 7; the third bending section 24 is connected to the first clearance section 22 and is set at an angle to the first clearance section 22, and extends from the first clearance section 22 toward the auxiliary moving terminal 3; the fourth bending section 34 is connected to the second clearance section 32 and is set at an angle to the second clearance section 32, and extends from the second clearance section 32 toward the auxiliary stationary terminal 2; the auxiliary stationary contact 5 is disposed on the third bending section 24; the auxiliary moving spring 7 is disposed on the fourth bending section 34; the auxiliary moving contact 6 is disposed on the auxiliary moving spring 7 and contacts the auxiliary stationary contact 5. By setting the third bending segment 24 and the fourth bending segment 34 extending towards each other, on the one hand, due to the larger installation space formed between the first clearance segment 22 and the second clearance segment 32, the third bending segment 24 and the fourth bending segment 34 can make the installation distance between the auxiliary stationary contact 5 and the auxiliary moving contact 6 closer, reduce the length required for the auxiliary moving spring 7, improve the structural strength of the auxiliary moving contact, and improve the service life of the auxiliary contact, thus realizing the reasonable installation and docking of the auxiliary stationary contact 5 and the auxiliary moving contact 6; on the other hand, by designing the bending angle, while ensuring the reliability of contact, the contact installation structure avoids occupying the installation space of the coil assembly 4, taking into account the three major advantages of avoiding the coil, reliable contact, and compact structure, further making the function of the relay 100 more stable and the assembly more reasonable.

[0036] In one embodiment, such as Figures 1 to 3As shown, the coil assembly 4 has two positioning holes 41, and both the third bending segment 24 and the fourth bending segment 34 have positioning pins 241. The two positioning pins 241 are respectively inserted into the two positioning holes 41 for positioning. Through the insertion and engagement of the positioning pins 241 and the positioning holes 41, precise positioning of the auxiliary stationary terminal 2, the auxiliary moving terminal 3, and the coil assembly 4 is achieved. This not only avoids relative displacement among the three components during assembly, eliminating interference problems, but also allows the bending radius of the third bending segment 24 and the fourth bending segment 34 to be determined by the engagement of the positioning pins 241 and the positioning holes 41. This ensures that when the positioning pins 241 and the positioning holes 41 are engaged, the bending radius of the third bending segment 24 and the fourth bending segment 34 allows the auxiliary contact parts to make normal contact, thereby reducing assembly errors. Furthermore, this positioning method eliminates the need for additional fixing parts, simplifying the assembly process. It ensures the stability of the internal structure of the relay 100 and provides a precise positioning reference for automated assembly, improving the efficiency and pass rate of automated assembly.

[0037] In one embodiment, such as Figure 4 and Figure 5 As shown, the auxiliary stationary terminal 2 has a first pre-formed bent portion 25, which is connected to the first clearance section 22 and the third bent section 24 respectively; and / or, the auxiliary moving terminal 3 has a second pre-formed bent portion 35, which is connected to the second clearance section 32 and the fourth bent section 34 respectively. By setting the first pre-formed bent portion 25 and the second pre-formed bent portion 35, the bending positions of the auxiliary stationary terminal 2 and the auxiliary moving terminal 3 can be determined in the design stage, avoiding operational errors caused by temporary operations during installation and improving the structural consistency of the product; it can also improve the structural strength of the terminal, reduce the risk of breakage at the bending point during assembly, simplify the assembly process, improve assembly efficiency, and adapt to large-scale and automated production. Furthermore, it is possible to flexibly choose to set only the first pre-formed bent portion 25, only the second pre-formed bent portion 35, or both according to actual needs, improving design flexibility.

[0038] The first prefabricated bending portion 25 and the second prefabricated bending portion 35 can be in the form of setting a notch or marking the bending position; in one embodiment, by setting a notch, the notch can also reduce the impact of material extrusion during bending, making the bending process smoother and reducing the possibility of breakage at the bending point.

[0039] In one embodiment, such as Figure 1 and Figure 2As shown, the relay 100 also includes a push assembly 8, which includes an armature 81 and a pusher 82. The armature 81 is rotatably connected to the coil assembly 4. The pusher 82 is connected to the armature 81 and abuts against the auxiliary moving spring 7. The push assembly 8 enables the transmission connection between the coil assembly 4 and the auxiliary moving contact 6. When the coil assembly 4 is energized, it drives the armature 81 to rotate, which in turn drives the auxiliary moving spring 7 to actuate via the pusher 82, thus closing and opening the auxiliary moving contact 6 and the auxiliary stationary contact 5. This ensures the reliability of the auxiliary contact's operation and, through the structural design of the pusher 82, avoids interference with the coil assembly 4 and auxiliary terminals during transmission. Furthermore, the rotatable connection between the armature 81 and the coil assembly 4 (yoke) is compatible with the installation space of the coil assembly 4, without occupying additional clearance space. This balances transmission reliability and assembly compatibility, improving the overall control logic of the relay 100. The armature 81 is reset after the coil is de-energized by the reaction force of the spring in the main contact part; the pusher 82 is made of insulating material to block the transmission of the magnetic flux of the armature 81 to the auxiliary moving spring 7.

[0040] This invention also proposes an assembly method for the relay 100, combined with... Figures 1 to 3 The specific assembly process of this assembly method is as follows: First, the auxiliary stationary contact 5 is installed to the third bending section 24 of the auxiliary stationary terminal 2 to form an auxiliary stationary assembly. Then, the auxiliary moving contact 6 is installed to the auxiliary moving spring 7, and finally, the auxiliary moving spring 7 is installed to the fourth bending section 34 of the auxiliary moving terminal 3 to form an auxiliary moving assembly. Different installation methods are used depending on the type of the auxiliary stationary contact 5 and the auxiliary moving contact 6. For example, if riveted contacts are used, rivet holes are formed in the third bending section 24 and the auxiliary moving spring 7, and then the auxiliary stationary contact 5 and the auxiliary moving contact 6 are fixed by riveting. The auxiliary moving spring 7 can be provided with rivet holes, and rivet posts are pre-set in the fourth bending section 34. The auxiliary moving spring 7 is then fitted onto the rivet posts in the fourth bending section 34 and riveted. To prevent the auxiliary moving spring 7 from rotating during use, at least two rivet posts should be provided to fix the auxiliary moving spring 7.

[0041] Next, install the auxiliary static component, the auxiliary moving component, and the coil component 4 onto the base 1 with their respective pins. Based on the general installation position of the fixed pin, determine that the coil component 4 is located between the two.

[0042] The pusher 82 is then installed onto the armature 81 to form the pusher assembly 8. The connection between the pusher 82 and the armature 81 can be achieved by plugging or by setting a buckle. The pusher assembly 8 is then installed onto the coil assembly 4, specifically by rotating the armature 81 onto the yoke of the pusher assembly 8.

[0043] Next, the fourth bending section 34 is bent along the second pre-made bending part 35 toward the auxiliary stationary component. The bending amplitude is controlled so that the positioning pin 241 is inserted into the positioning socket 41 of the coil assembly 4 to achieve positioning. When the positioning pin 241 is inserted into the positioning socket 41, the auxiliary moving spring 7 will simultaneously come into contact with the pusher 82, and the auxiliary moving spring 7 will undergo elastic deformation. The degree of elastic deformation corresponds to the degree of deformation of the preset elastic force of the auxiliary moving spring 7 when the auxiliary moving contact 6 and the auxiliary stationary contact 5 are in contact and connected during the use of the relay 100.

[0044] Finally, the third bending section 24 is bent along the first pre-made bending part 25 toward the auxiliary moving component. The bending amplitude is controlled so that the positioning pin 241 is inserted into the positioning socket 41 for positioning. At the same time, the auxiliary stationary contact 5 abuts against the auxiliary moving contact 6 to complete the assembly of the relay 100.

[0045] During the assembly process described above, a larger installation space was reserved for the coil assembly 4, which largely avoided interference between the coil assembly 4 and the auxiliary stationary terminal 2 or the auxiliary moving terminal 3. Simultaneously, precise positioning was achieved through step-by-step bending and the cooperation of the positioning pin 241 with the socket, ensuring the assembly accuracy of each component and adapting to the operational logic of automated assembly, thus solving the problem of difficult assembly of traditional through-hole terminals. After the assembly process is completed, a relay 100 with normally closed auxiliary contacts is obtained. When the coil is not energized, the auxiliary contacts are in contact and conducting, and the auxiliary moving spring 7 is in a deformed state. When the coil is energized, the armature 81 rotates, causing the pusher 82 to rotate and move away from the auxiliary moving spring 7. At this time, the auxiliary moving spring 7 resets under the action of elasticity, causing the auxiliary stationary contact 5 and the auxiliary moving contact 6 to separate.

[0046] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
