Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a low-temperature power rise relay. Background Technology

[0002] With the development of new energy technologies such as photovoltaic energy storage, solar energy, and wind energy, the environment for the use of high-power relays is becoming increasingly demanding, and the requirements for the heat dissipation capacity and service life of the relays themselves are also becoming increasingly stringent. Therefore, it is necessary to propose a low-temperature rise-type power relay.

[0003] High-power relays on the market generally use a single-contact structure design for current carrying and heat conduction. This results in high contact resistance between contacts, high heat generation, and generally poor heat conduction capacity. At the same time, the current carrying area of ​​the spring is relatively small, leading to poor overload capacity. This causes the relay to overheat, have a short service life, fail to meet market demands, and severely limit the relay's operating environment.

[0004] Therefore, those skilled in the art have provided a low-temperature power relay to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a low-temperature power rise relay, including a base plate, and further comprising:

[0006] The outer casing is disposed on one side of the base plate;

[0007] The coil assembly is disposed inside the base plate;

[0008] Both the iron core and the yoke are fixedly installed on the outside of the coil assembly;

[0009] An armature spring contact assembly is disposed outside the coil assembly;

[0010] The main load static A terminal contact assembly is located inside the coil assembly.

[0011] As a further improvement to this technical solution, the coil assembly includes a frame fixedly mounted on a base plate, an enameled wire on the outside of the frame, two coil terminals inside the frame, and the iron core and yoke both fixedly mounted on the outside of the frame.

[0012] As a further improvement to this technical solution, the armature spring contact assembly includes an armature disposed outside the frame, a spring disposed outside the armature, and two mounting holes for mounting moving contacts inside the spring.

[0013] As a further improvement to this technical solution, the main load stationary A terminal contact assembly includes a stationary A terminal fixedly installed inside the frame, and two stationary contacts are fixedly installed inside the stationary A terminal.

[0014] As a further improvement to this technical solution, the interior of the frame is provided with a mounting slot for mounting the B terminal.

[0015] As a further improvement to this technical solution, both the base plate and the outer shell are provided with retaining wall ribs.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this type of low-temperature power relay, the coil assembly, armature spring contact assembly, and main load stationary A terminal contact assembly are configured. When assembling the relay as a whole, the iron core and yoke are first installed into the coil assembly and riveted together, thus completing the assembly of the magnetic system. After the magnetic system is assembled, the armature spring contact assembly, main load stationary A terminal contact assembly, and B terminal are then installed into the coil assembly after riveting the iron core and yoke, thus completing the assembly of the magnetic system and the load system. Finally, the outer casing is installed and sealed with adhesive to secure it, thereby completing the anti-reflective coating. The assembly of the protection system allows for the overall assembly of the relay, facilitating user operation. This device, designed with a double-contact structure and an increased current-carrying area for the spring, utilizes the increased contact area and reduced contact resistance to effectively decrease heat generation between contacts, thus lowering the product's temperature rise. Combined with the newly designed spring with an increased current-carrying area, the product's overload capacity and heat dissipation are enhanced, significantly accelerating heat conduction efficiency and rapidly reducing the relay's temperature rise. This effectively extends the relay's lifespan, improves its practicality, and saves time and effort. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides a low-temperature power relay, including a base plate 1, and further comprising:

[0026] The outer casing 2 is located on one side of the base plate 1;

[0027] The coil assembly is located inside the base plate 1;

[0028] Both the iron core 7 and the yoke 6 are fixedly installed on the outside of the inline package assembly;

[0029] The armature spring contact assembly is located outside the in-line package assembly;

[0030] The main load static A terminal contact assembly is located inside the in-line package assembly.

[0031] The working principle described above is as follows: When assembling the relay as a whole, simply install the iron core 7 and yoke 6 into the coil assembly for riveting. This completes the assembly of the magnetic system. After the magnetic system is assembled, install the armature spring contact assembly, the main load stationary A terminal contact assembly, and the B terminal 13 into the coil assembly after riveting the iron core 7 and yoke 6. This completes the assembly of the magnetic system and the load system. Finally, install the outer casing 2 and base plate 1 and seal them with glue to complete the assembly of the protection system. This allows the relay to be assembled as a whole, making it convenient for users. This device, through its double-contact structure and increased current-carrying area of ​​the spring 9, utilizes the characteristic of double contacts to increase the contact area and reduce the contact resistance of the product, effectively reducing the heat generated between the contacts and thus reducing the temperature rise of the product. Combined with the new structure and increased current-carrying area of ​​the spring 9, the overload capacity and heat dissipation capacity of the product are enhanced, greatly accelerating the heat conduction efficiency, causing the temperature rise of the relay to drop rapidly, effectively extending the service life of the relay, improving the practicality of the relay, and saving time and effort.

[0032] To effectively assemble the magnetic system, the coil assembly includes a frame 3 fixedly mounted on the base plate 1. The frame 3 has an enameled wire 4 on its exterior and two coil terminals 5 inside. The iron core 7 and yoke 6 are both fixedly mounted on the exterior of the frame 3. When assembling the magnetic system, simply fix the frame 3 on the base plate 1 first, then fix the enameled wire 4 and coil terminals 5. Next, insert the iron core 7 and yoke 6 into the frame 3 for riveting, thus completing the assembly of the magnetic system.

[0033] Considering that when the relay is under load, the heat generated by a single contact structure and the spring 9 will increase over time, and the internal temperature of the relay will also increase, the armature spring contact assembly includes an armature 8 set outside the frame 3, and a spring 9 set outside the armature 8. The spring 9 has two mounting holes for mounting the moving contact 10. This device is designed with a double contact structure and the current-carrying area of ​​the spring 9 is increased (the double contact structure is two moving contacts 10 and two stationary contacts 12). By utilizing the characteristic of the double contact to increase the contact area and reduce the contact resistance of the product, the heat generated between the contacts can be effectively reduced, thereby reducing the temperature rise of the product. Combined with the new structure of the spring 9 with increased current-carrying area, the overload capacity and heat dissipation capacity of the product are enhanced, effectively accelerating the heat transfer efficiency, rapidly reducing the temperature rise of the relay, and effectively extending the service life of the relay.

[0034] In order for the relay to function properly, the main load stationary A terminal contact assembly includes a stationary A terminal 11 fixedly installed inside the frame 3. Two stationary contacts 12 are fixedly installed inside the stationary A terminal 11. By setting up two stationary contacts 12 and two moving contacts 10, the characteristics of increasing the contact area and reducing the contact resistance of the product can be effectively utilized by the double contact structure. This effectively reduces the heat generation between the contacts, reduces the temperature rise of the relay, extends the service life of the relay, and enables the relay to function properly, thus effectively improving the practicality of the relay.

[0035] In order to effectively assemble the relay as a whole, the frame 3 has a mounting slot for installing the B terminal 13. When it is necessary to assemble the relay as a whole, simply insert the armature spring contact assembly, the main load stationary A terminal contact assembly and the B terminal 13 into the coil assembly after riveting the iron core 7 and the yoke 6 respectively and fix them. At this time, the assembly of the magnetic system and the load system can be completed, so that the relay can be assembled as a whole, and then the user can use the relay normally.

[0036] In addition, in order to further extend the service life of the relay, both the base plate 1 and the outer shell 2 are provided with retaining wall protrusions 14. The retaining wall protrusions 14 on the base plate 1 and the outer shell 2 have the function of increasing the insulation distance, enabling the relay to be suitable for greater load requirements, thereby improving the relay's market viability and customer satisfaction.
