Description

Technical Field

[0001] This application relates to the technical field of electrical control devices, and in particular to a moving spring mounting structure and a relay. Background Technology

[0002] A relay is an electronically controlled device that uses the magnetic field generated by the energized coil assembly to drive the push rod assembly, causing the moving and stationary contacts to close, thereby controlling the circuit. It plays a role in automatic adjustment, safety protection, and circuit switching in the circuit.

[0003] When the relay is working, the coil assembly drives the push rod assembly to move, which in turn drives the auxiliary moving spring to move through the base of the push rod assembly, thereby connecting or separating the auxiliary moving spring from the auxiliary contact. Currently, the auxiliary moving spring and the base are generally molded into a single structure using injection molding. The injection molding process is complex, involving molds, injection molding materials, etc., and uses a large amount of materials, making production difficult and costly. Utility Model Content

[0009] In the above-described moving spring mounting structure, the base is the basic component used to mount the integrated mounting component. After the mounting component is installed on the base, its mounting portion extends outwards and remains outside the base. In this way, the auxiliary moving spring can connect with the mounting portion, thereby achieving assembly and fixation onto the base. Compared to traditional technologies, this solution, by configuring the mounting component on the base, enables the auxiliary moving spring to be assembled onto the base through connection with the mounting component.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] 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.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1 The relay 100 described in one embodiment of this application can be any of the following: a high-voltage DC relay, a high-voltage AC relay, etc., and can be flexibly selected according to actual needs.

[0051] Please continue reading. Figures 1 to 3 More specifically, the relay 100 includes a moving spring mounting structure 10. The moving spring mounting structure 10 includes a base 11, a mounting member 12, and an auxiliary moving spring 13.

[0052] Please continue reading. Figure 4 and Figure 5 The base 11 houses the fixed mounting component 12 and the auxiliary moving spring 13. Specifically, the base 11 is a component of the push rod assembly of the relay 100. The push rod assembly, through its mounting and engagement with the coil assembly, generates a magnetic field during operation, driving the push rod assembly to move. This allows the base 11 to move the auxiliary moving spring 13 along a preset path towards or away from the auxiliary contact 20, thereby achieving contact or disconnection with the auxiliary contact 20, thus enabling detection and feedback of the contact status between the moving and stationary contacts of the relay 100.

[0053] Optionally, the base 11 is made of plastic and is integrally molded by injection molding, which has high structural strength and light weight, helping to achieve a lightweight design for the relay 100.

[0054] In this application, the base 11 has a rectangular shape, which is simple and regular in structure. It is easy to process and shape, easy to install and use, and avoids occupying too much installation space and avoids interference with other components of the relay 100.

[0055] Please continue reading. Figure 4 and Figure 5 More specifically, the mounting member 12 is mounted on the base 11, and the mounting member 12 has a mounting portion 121 extending out of the base 11; the auxiliary moving spring 13 is connected to the mounting portion 121.

[0056] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the moving spring mounting structure 10 of the above solution, the base 11 is a basic component used to load the integrated mounting component 12. After the mounting component 12 is installed on the base 11, the mounting part 121 of the mounting component 12 extends out and remains outside the base 11. In this way, the auxiliary moving spring 13 can be connected with the mounting part 121, thereby achieving assembly and fixation onto the base 11. Compared with the traditional technology, this solution, by configuring the mounting component 12 on the base 11, realizes that the auxiliary moving spring 13 is assembled onto the base 11 by connecting with the mounting component 12. This installation method effectively replaces the traditional injection molding method, eliminating the inconvenience of integral molding of the auxiliary moving spring 13 and the base 11 caused by the use of injection molds, injection plastics, and other materials. Not only is the installation structure and method simple and easy to operate and implement, but the processing difficulty and cost are also greatly reduced, significantly improving manufacturability.

[0057] In one embodiment, the auxiliary moving spring 13 is riveted to the mounting part 121. This simplifies the installation method and structure of the auxiliary moving spring 13 and the mounting part 121, and facilitates the installation and fixation of the auxiliary moving spring 13 to the base 11 during processing.

[0058] Please continue reading. Figures 4 to 6 More specifically, in one embodiment, the mounting member 12 is configured as a riveting member, with a rivet 122 provided on the mounting portion 121. The auxiliary movable spring 13 has a riveting hole 1311, and the rivet 122 passes through the riveting hole 1311 to be riveted and fixed to the connecting portion 131. Therefore, during installation, the rivet 122 can be inserted into the riveting hole 1311 and then riveted and fixed to the auxiliary movable spring 13, thereby completing the riveting and fixing of the auxiliary movable spring 13 to the mounting member 12, and realizing the assembly of the auxiliary movable spring 13 onto the base 11. The riveting process is simple, easy to implement, and has high connection strength.

[0059] Furthermore, in order to improve the connection strength and reliability between the auxiliary moving spring 13 and the mounting part 12, the number of rivets 122 and rivet holes 1311 can be two or more. By installing them in a one-to-one riveting manner, the number of riveting positions between the auxiliary moving spring 13 and the mounting part 12 is increased, thereby achieving the above-mentioned purpose.

[0060] In addition, as an alternative to the above embodiments, in another embodiment, the mounting member 12 is configured as a riveting member, the mounting part 121 has a riveting hole 1311, and the auxiliary moving spring 13 is provided with a rivet 122, which passes through the riveting hole 1311 to be riveted and fixed with the mounting part 121.

[0061] This embodiment achieves essentially the same technical effect as the above embodiment. The only difference lies in the arrangement of the rivet 122 and the rivet hole 1311. Therefore, it will not be described in detail here. Please refer to the above embodiment for understanding.

[0062] It should be noted that the mounting part 121 and the connecting part 131 may not be provided with rivets 122 or rivet holes 1311 alone. In other words, the mounting part 121 may be provided with rivets 122 and rivet holes 1311 at the same time, and the connecting part 131 may also be provided with rivets 122 and rivet holes 1311 at the same time, as long as the mounting part 121 and the connecting part 131 can be riveted together by the rivets 122 and rivet holes 1311 arranged in a symmetrical manner.

[0063] It should be noted that, in order to replace the traditional injection molding method, in addition to the riveting method mentioned above, the following embodiments can also be used.

[0064] Furthermore, the auxiliary moving spring 13 and the mounting part 121 are provided with two riveting positions, which are symmetrically arranged on both sides of the mounting part 121. That is, the auxiliary moving spring 13 and the mounting part 121 are riveted and fixed by two sets of rivets 122 and rivet holes 1311.

[0065] This arrangement not only facilitates the installation of two rivets 122 on the mounting part 121, but also forms two symmetrical riveting structures with the auxiliary moving spring 13, so that the auxiliary moving spring 13 is subjected to uniform force, and significantly improves the strength and firmness of the riveting between the auxiliary moving spring 13 and the mounting part 121.

[0066] In another optional embodiment, the mounting component 12 is made of metal, and the base 11 is made of plastic, with the mounting component 12 and the base 11 forming a single integral structure. This facilitates the manufacturing of the mounting component 12 and the base 11, and the resulting integral structure has high strength, ensuring a reliable connection between the mounting component 12 and the base 11.

[0067] Alternatively, in another optional embodiment, both the auxiliary moving spring 13 and the mounting member 12 are made of metal, with the thickness of the mounting member 12 being greater than the thickness of the auxiliary moving spring 13, or the structural stiffness of the mounting member 12 being greater than the structural stiffness of the auxiliary moving spring 13. This arrangement ensures that the mounting member 12 provides more reliable loading support for the auxiliary moving spring 13, guaranteeing the structural performance of the auxiliary moving spring 13, so that the auxiliary moving spring 13 is less likely to undergo irreversible deformation when it comes into contact with the auxiliary contact 20.

[0068] Please continue reading. Figures 4 to 6In an optional embodiment, the auxiliary moving spring 13 includes a connecting portion 131 and a contact portion 132. The connecting portion 131 is connected to the contact portion 132 and is also connected to the mounting portion 121. The contact portion 132 is used to contact or separate from the auxiliary contact 20. The connecting portion 131 and the contact portion 132 can be integrally formed or detachably assembled, depending on actual needs. For example, in this embodiment, the connecting portion 131 and the contact portion 132 are an integral structure, which ensures excellent structural performance of the auxiliary moving spring 13 while reducing the number of parts and improving the production and assembly efficiency of the relay 100.

[0069] The auxiliary moving spring 13 is a metal sheet, such as, but not limited to, a copper sheet. By connecting the connecting part 131 to the mounting part 121, the auxiliary moving spring 13 is connected to the mounting part 12 and then assembled onto the base 11. The contact part 132 connected to the connecting part 131 is specifically used to make contact with the auxiliary contact 20 to realize the detection function of the auxiliary contact 20.

[0070] In one embodiment, the movable spring mounting structure 10 further includes a connector (not shown in the figure), and the connecting portion 131 of the auxiliary movable spring 13 is assembled and fixed to the mounting portion 121 through the connector. Therefore, the connecting portion 131 can be connected to the connector, and then the connector can be connected to the mounting portion 121 to achieve assembly and fixation between the connecting portion 131 and the mounting portion 121. Compared with the injection molding process, the connection method is simple and highly feasible.

[0071] Specifically, in one embodiment, the connector is configured as a threaded component, such that the connecting portion 131 is screwed and fixed to the mounting portion 121 by the threaded component.

[0072] Alternatively, as an alternative to the above embodiments, in another embodiment, the connector is configured as an adhesive, so that the connecting part 131 is bonded and fixed to the mounting part 121 by the adhesive.

[0073] Alternatively, as an alternative to the two embodiments described above, in another embodiment, the connector is configured as a locking member, which is disposed on one of the connecting part 131 and the mounting part 121, and the other of the connecting part 131 and the mounting part 121 has a locking position, and the locking member engages with the locking position to fasten and fix the connecting part 131 and the mounting part 121.

[0074] As can be seen, by setting the connector as any one of the threaded parts, adhesive parts, snap-fit ​​parts, and magnetic parts, the mounting part 121 and the connecting part 131 can be fixed by threaded connection, adhesive, snap-fit ​​connection, or magnetic connection. The threaded parts (such as screws, bolts, etc.) and adhesive parts (such as double-sided tape, glue, etc.) used are easy to obtain, have low usage costs, and the installation method is simple, which helps to reduce the installation difficulty of the auxiliary moving spring 13 and thus improve the installation efficiency.

[0075] Specifically, considering that both the connecting part 131 and the mounting part 121 are thin sheet structures, the threaded component used when adopting the threaded installation method is a combination of bolt and nut, so as to reliably lock the connecting part 131 and the mounting part 121 by screwing the bolt and nut together.

[0076] In addition, in one embodiment, along the first direction of the moving spring mounting structure 10, the mounting portion 121 is stacked on top of the connecting portion 131.

[0077] For example, the first direction can refer to the height direction of the moving spring mounting structure 10, such as... Figure 6 Arrow S1 points to the top. The mounting part 121 is stacked on top of the connecting part 131, and the mounting part 121 and the connecting part 131 are in contact and fit together. This allows the mounting part 121 to install and fix the connecting part 131 and provide support and reinforcement for the contact part 132, thereby reducing the suspension length of the contact part 132 and improving the structural strength and resistance to compression and deformation of the contact part 132.

[0078] Furthermore, based on the above embodiment, a curved transition structure is provided on the end face of the mounting part 121 away from the base 11 and facing the connecting part 131. The curved transition structure can effectively reduce the local concentrated stress of the mounting part 121 on the connecting part 131, avoid fatigue damage to the connecting part 131, and at the same time, the curved transition structure provides a clearance effect for the contact piece 1321, which is beneficial to the up and down swing of the contact piece 1321.

[0079] Optionally, the curved surface transition structure may adopt, but is not limited to, a rounded corner structure.

[0080] Please continue reading. Figure 6 and Figure 7 Furthermore, in this application, there are two of each of the mounting part 121, the connecting part 131, and the contact part 132, and they are assembled in a one-to-one correspondence. One set of mounting parts 121, connecting parts 131, and contact parts 132 protrudes along the second direction of the moving spring mounting structure 10 and is disposed on one side of the base 11, while another set of mounting parts 121, connecting parts 131, and contact parts 132 protrudes along the second direction of the moving spring mounting structure 10 and is disposed on the other side of the base 11.

[0081] The second direction refers to the width direction of the moving spring mounting structure 10, that is, as shown in the figure. Figure 6 Arrow S2 points in the diagram. Specifically, the second direction of the moving spring mounting structure 10 intersects with the first direction. More specifically, the second direction is perpendicular to the first direction.

[0082] By providing a set of mounting portions 121, connecting portions 131, and contact portions 132 protruding from opposite sides of the base 11 along the second direction S2, and by assembling the two sets of connecting portions 131 with the mounting portions 121 respectively, the auxiliary moving spring 13 is mounted and fixed at two points on both sides, greatly improving the stability and reliability of the auxiliary moving spring 13 installation. Furthermore, two contact portions 132 can be simultaneously connected to two auxiliary contacts 20 in a one-to-one correspondence, significantly improving the detection reliability and accuracy of the constructed dual-auxiliary contact detection structure.

[0083] Please continue reading. Figure 7 Furthermore, based on the above embodiments, the auxiliary moving spring 13 also includes a connecting part 133, which is connected between two connecting parts 131 and attached to the base 11, and the connecting part 133 has an assembly through hole 1331.

[0084] Please continue reading. Figure 2 , Figure 5 and Figure 6 The moving spring mounting structure 10 also includes a push rod 14, which passes through the mounting through hole 1331, with one end of the push rod 14 mounted on the base 11 and the other end of the push rod 14 extending outward toward the base 11.

[0085] Connecting part 133 connects the two connecting parts 131, thereby connecting the two sets of connecting parts 131 and mounting part 121 into one unit, improving the overall structural performance of the auxiliary moving spring 13. By machining a mounting through hole 1331 on the connecting part 133, the push rod 14 mounted on the base 11 can pass through the mounting through hole 1331, thereby achieving non-interference assembly with the connecting part 133. At the same time, it allows the connecting part 133 to be attached to the bottom surface of the base 11, making the installation structure more compact and saving installation space. In addition, the contact between the connecting part 133 and the base 11 increases the contact support area between the auxiliary moving spring 13 and the base 11, which helps to improve the assembly stability and firmness of the auxiliary moving spring 13 and the base 11.

[0086] Please continue reading. Figure 6 and Figure 7 In addition, in one embodiment, the contact portion 132 includes a contact piece 1321, one side of which is connected to the connection portion 131. The contact piece 1321 is used to contact or separate from the auxiliary contact 20.

[0087] Furthermore, the contact portion 132 also includes a bent piece 1322, which is disposed between the connecting portion 131 and the contact piece 1321. One side of the bent piece 1322 is connected to the connecting portion 131, and the other side of the bent piece 1322 is connected to the contact piece 1321.

[0088] The bent piece 1322 is connected between the connecting part 131 and the contact piece 1321 to provide the contact piece 1321 with excellent elasticity, thereby ensuring that the contact piece 1321 and the auxiliary contact 20 are in reliable contact for a long time and at high frequency, and avoiding deformation of the contact piece 1321, which would prevent the contact piece 1321 from making normal and effective contact with the auxiliary contact 20.

[0089] For example, the bending piece 1322 is configured to form an arched protrusion that creates a uniform transition between the connecting part 131 and the contact piece 1321, and the number can be more than one; and when two or more bending pieces 1322 are provided, the protrusion direction of different bending pieces 1322 can be along the same direction of the thickness of the auxiliary moving spring 13, or they can be along different directions of the thickness of the auxiliary moving spring 13, and can be flexibly selected according to actual needs.

[0090] In addition, the contact portion 132 also includes an auxiliary contact piece 1323, which is mounted on the side of the contact piece 1321 facing the auxiliary contact 20, and is used to contact or separate from the auxiliary contact 20.

[0091] The thickness of the auxiliary contact 1323 is greater than the thickness of the contact 1321; and / or the structural strength of the auxiliary contact 1323 is greater than the structural strength of the contact 1321.

[0092] Therefore, an auxiliary contact piece 1323 with greater thickness and higher structural strength is installed on the contact piece 1321 for contact and engagement with the auxiliary contact 20. This can prevent the contact piece 1321 from wearing and deforming due to contact with the auxiliary contact 20, and helps to improve the durability of the auxiliary moving spring 13.

[0093] 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 there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of 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. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
