Description

Technical Field

[0001] This utility model belongs to the field of relay technology, specifically relating to an anti-vibration relay. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in an electrical output circuit when a change in the input quantity reaches a specified requirement. Relays have both a control system and a controlled system, and are commonly used in automated control circuits, playing roles such as automatic adjustment, safety protection, and circuit switching. Fifth-generation signal relays have emerged, which are smaller, consume less power, and have higher reliability.

[0003] Currently, relays are typically connected directly to the mounting base using bolts during assembly. However, the shock-absorbing design between the relay and the mounting base may be insufficient, making the relay prone to loosening or damage when subjected to external vibrations or impacts. Furthermore, the lack of protection around the bolt connections allows dust to accumulate at the bolt joints, leading to difficulties in disassembly and assembly. Utility Model Content

[0004] The purpose of this invention is to provide an anti-vibration relay, which addresses the problem in the prior art where relays are typically connected directly to the mounting base using bolts. However, the anti-vibration design between the relay and the mounting base may be insufficient, leading to the relay easily loosening or being damaged when subjected to external vibrations or impacts. Furthermore, the lack of protection in the bolted connection allows dust to easily accumulate at the bolt joint, making disassembly and assembly difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-damping relay, comprising a relay body, a mounting base connected to the bottom end of the relay body, a connecting plate mounted to the front end of the relay body, a fixing locking plate connected to the side wall of the relay body, an armature connected to the bottom end of the relay body, bolts connected to the surface of the fixing locking plate, a spring connected to the bottom of the fixing locking plate, and a protective cover connected to the bottom end of the fixing locking plate.

[0006] In a preferred embodiment of this anti-vibration relay, the spring is sleeved on the outer surface of the bolt, and the top end of the spring is connected to the bottom end of the fixing locking block.

[0007] As a preferred embodiment of the anti-vibration relay of this utility model, the protective cover is U-shaped, and the outer surface of the bolt and spring is covered by the cavity inside the protective cover.

[0008] As a preferred embodiment of the anti-vibration relay of this utility model, a support rod is installed at the front end of the relay body, and two protrusions are connected to the surface of the support rod. A limiting plate is rotatably connected between the two protrusions, and a threaded groove is provided at the end of the limiting plate.

[0009] As a preferred embodiment of the anti-vibration relay of this utility model, a limiting block is installed at the front end of the relay body, a groove is provided on the side wall of the limiting block, and a threaded pin is connected to the front end of the limiting block.

[0010] In a preferred embodiment of this anti-vibration relay, the back end of the limiting plate is fitted with the front end of the connecting plate, and the length of the limiting plate is greater than the length of the connecting plate.

[0011] In a preferred embodiment of the anti-vibration relay of this utility model, the threaded pin passes through the limiting block and is threadedly connected inside the threaded groove, and the limiting plate is fixedly connected to the limiting block through the threaded pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention achieves a convenient connection between the fixing locking block and the mounting base through the ingenious cooperation of the spring and the protective cover. During this process, the spring deforms and is compressed, and its elastic force effectively mitigates the impact of vibrations generated during relay operation on the armature connection. Simultaneously, the connection between the bolt and the mounting base is fully protected by the protective cover, preventing dust accumulation and thus avoiding difficulties in bolt disassembly and stripping caused by dust. Furthermore, the design of the limiting plate not only facilitates the stable fixing of the connecting plate but also allows for rotational opening via the support rod. This feature greatly simplifies the disassembly and assembly of the connecting plate, thereby facilitating the maintenance of the relay body. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a vibration-damping relay, including a relay body 1, a mounting base 2 connected to the bottom end of the relay body 1, a connecting plate 3 installed at the front end of the relay body 1, a fixing locking piece 4 connected to the side wall of the relay body 1, an armature 8 connected to the bottom end of the relay body 1, a bolt 5 connected to the surface of the fixing locking piece 4, a spring 6 connected to the bottom of the fixing locking piece 4, and a protective cover 7 connected to the bottom end of the fixing locking piece 4.

[0023] In a preferred embodiment: the spring 6 is sleeved on the outer surface of the bolt 5, and the top end of the spring 6 is connected to the bottom end of the fixing locking block 4.

[0024] In a preferred embodiment: the protective cover 7 is U-shaped, and the outer surface of the bolt 5 and the spring 6 is covered by the cavity inside the protective cover 7.

[0025] In this embodiment, the clever cooperation between the spring 6 and the protective cover 7 enables a convenient connection between the fixing locking block 4 and the mounting base 2. During this process, the spring 6 can deform and be compressed, and its elastic force effectively mitigates the impact of vibration generated by the relay body 1 during operation on the armature 8 connection. At the same time, the connection between the bolt 5 and the mounting base 2 is fully protected by the protective cover 7, preventing dust accumulation at this location and thus preventing difficulties in disassembling and assembling the bolt 5 and stripping caused by dust.

[0026] Specifically, the relay body 1 is brought close to the mounting base 2, causing the bolt 5 on the surface of the locking plate 4 to rotate and align with the mounting groove on the mounting base 2. During this process, the spring 6 at the bottom of the locking plate 4 is compressed and deformed. Subsequently, the elastic force of the spring 6 effectively reduces the impact of vibrations generated by the relay body 1 during operation on the armature 8 connection. In addition, the protective cover 7 at the bottom of the locking plate 4 can shield the bolt 5, preventing dust accumulation and thus avoiding difficulties in disassembling and assembling the bolt 5 and stripping caused by dust accumulation.

[0027] Example 1

[0028] Please see Figure 1-4 A support rod 9 is installed at the front end of the relay body 1. Two protrusions 10 are connected to the surface of the support rod 9. A limit plate 11 is rotatably connected between the two protrusions 10. A threaded groove 14 is provided at the end of the limit plate 11.

[0029] In a preferred embodiment: a limiting block 12 is installed at the front end of the relay body 1, a groove 15 is provided on the side wall of the limiting block 12, and a threaded pin 13 is connected to the front end of the limiting block 12.

[0030] In a preferred embodiment: the back end of the limiting plate 11 is attached to the front end of the connecting plate 3, and the length of the limiting plate 11 is greater than the length of the connecting plate 3.

[0031] In a preferred embodiment: the threaded pin 13 passes through the limiting block 12 and is threadedly connected inside the threaded groove 14, and the limiting plate 11 is fixedly connected to the limiting block 12 through the threaded pin 13.

[0032] In the embodiment, the design of the limiting plate 11 not only facilitates the stable fixing of the connecting plate 3, but also enables it to be rotated and opened via the support rod 9. This feature greatly facilitates the disassembly and assembly of the connecting plate 3, thereby making it easier to inspect and maintain the relay body 1.

[0033] Specifically: to disconnect the limiting plate 11 from the limiting block 12, simply remove the threaded pin 13. Then, rotate the limiting plate 11 along the groove 15 to release it from its contact with the connecting plate 3. After that, pull the connecting plate 3 outward to inspect the inside of the relay body 1. After the inspection is completed, screw the limiting plate 11 back into the groove 15, and secure the limiting plate 11 by threading the threaded pin 13 through the limiting block 12 and threading it into the threaded groove 14.

[0034] In summary, this utility model utilizes the cooperation of spring 6 and protective cover 7 to conveniently connect and fix the locking plate 4 to the mounting base 2. Spring 6 can deform and mitigate the impact of relay body 1 vibration on armature 8. Protective cover 7 protects the connection parts of bolt 5, preventing dust accumulation that could lead to difficulties in disassembly and stripping. In addition, the limiting plate 11 can be rotated open via support rod 9, facilitating the disassembly and assembly of connecting plate 3 and the maintenance of relay body 1.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
