Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a relay with an increased insulation distance structure. Background Technology

[0002] With the development of new energy technologies such as photovoltaic energy storage, solar energy, and wind energy, the safety conditions for the use of relays are becoming increasingly stringent, and the lifespan of the relays themselves is also being required to be longer.

[0003] Miniature relays are automatic switching devices based on the principle of electromagnetic induction, mainly composed of a coil, an armature, and a contact system. When the coil is energized, it generates a magnetic field that attracts the armature, and through mechanical linkage, changes the on / off state of the contacts, thus enabling the control of high-power circuits with low-power signals.

[0004] Currently, traditional power relays have the following problems:

[0005] Due to size limitations, many existing technologies cannot meet the requirements for miniature relays in medium and high voltage applications. They also fail to meet national standards for reinforced insulation or medium and high voltage applications, thus failing to meet customer requirements. Furthermore, because of their size, miniature relays often have poor insulation and short lifespans due to the difficulty in achieving the same insulation structure as conventional relays. Additionally, traditional relays have shorter creepage distances, resulting in lower safety during use. Utility Model Content

[0006] The purpose of this invention is to provide a relay with an increased insulation distance structure to solve the problems mentioned in the background art.

This effectively improves the safety of the relay in medium and high voltage fields and greatly increases the creepage distance of the relay. It effectively prevents electrical faults or short circuits from occurring in electrical equipment during normal operation or fault conditions, thereby ensuring the safe operation of electrical equipment and improving electrical safety performance.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] Please see Figures 1-6 A relay with an increased insulation distance structure includes a housing 10; a base plate 20 installed at the bottom of the housing 10; a relay frame 30 installed on the top of the base plate 20 and located inside the housing 10; a load current circuit mechanism 40 installed on the relay frame 30; and a relay magnetic circuit structure 50 installed inside the relay frame 30 and extending to the outside. Corresponding adhesive grooves are provided inside the housing 10, base plate 20, and relay frame 30, and the housing 10, base plate 20, and relay frame 30 are covered with adhesive through the adhesive grooves. The load current circuit mechanism 40 includes: a stationary plate assembly 401 installed inside the relay frame 30; and a moving plate assembly 402 that abuts against the stationary plate assembly 401. The moving plate assembly 402 extends to the side of the relay magnetic circuit structure 50 and abuts against the relay magnetic circuit structure 50. Two stationary plate assemblies 401 are provided, and the two stationary plate assemblies 401 abut against each other.

[0032] In this design, the base plate 20 and the insulating cover 301 are designed with corresponding ribs and glue grooves. The glue is applied to penetrate and tightly connect the components, forming an external secondary insulation connection.

[0033] In actual assembly and use, the relay in this scheme generates a magnetic field after being energized, which drives the relay magnetic circuit structure 50 to operate and triggers the moving plate assembly 402, which is in contact with the relay magnetic circuit structure 50, to operate. This causes the moving plate assembly 402, which is in a power-off interval, to contact the stationary plate assembly 401, thereby realizing the relay energization operation.

[0034] For details, please refer to the following: Figure 1 and Figure 3The relay frame 30 is composed of an insulating cover 301 and an inner frame 302. The inner frame 302 is located inside the insulating cover 301. The insulating cover 301 is a fully enclosed structure with vertical connection. The inner side of the insulating cover 301 is provided with a relay magnetic circuit structure 50 located on the side of the inner frame 302. The inner frame 302 is equipped with a stationary plate assembly 401, and the outer side of the insulating cover 301 is equipped with a moving plate assembly 402.

[0035] The new invention, a relay with an increased insulation distance structure, effectively improves the insulation effect of the relay after it is energized by the structural shape of the insulation cover 301 and the design of its internal ribs and glue grooves, without affecting the normal operation of the relay's magnetic circuit structure 50.

[0036] For details, please refer to the following: Figure 3 , Figure 5 and Figure 6 The static plate assembly 401 includes: a relay static plate 4011 installed inside the inner frame 302; an electrostatic contact 4012 installed inside the relay static plate 4011 and extending to the outside, the relay static plate 4011 passing through the inner frame 302 and extending to the bottom of the base plate 20, and another electrostatic contact 4012 abutting against the side of the electrostatic contact 4012.

[0037] In this scheme, two electrostatic contacts 4012 are provided between the two static relay plates 4011, and a moving plate assembly 402 is provided between the two electrostatic contacts 4012.

[0038] For details, please refer to the following: Figure 3 , Figure 5 and Figure 6 The moving plate assembly 402 includes: a moving contact 4021 that abuts against the electrostatic contact 4012; a relay plate 4022 on which the moving contact 4021 is mounted; and a moving plate bracket 4023 connected to the relay plate 4022. The moving plate bracket 4023 is mounted on the outside of the insulating cover 301, and the bottom of the relay plate 4022 extends to the bottom of the base plate 20.

[0039] The new type of relay with increased insulation distance structure, through the design of the "L"-shaped structure of the relay plate 4022, can be normally squeezed and bent, and triggers the operation of the moving contact 4021 connected to the relay plate 4022 to realize the function of power on and off.

[0040] For details, please refer to the following: Figure 1The relay magnetic circuit structure 50 includes: an enameled wire 501 disposed on the outer side of the middle part of the inner frame 302; an iron core 502 penetrating the center of the inner frame 302; and a yoke 503 disposed at the bottom of the insulating cover 301 and mounted on the top of the base plate 20, wherein the yoke 503 is provided with the iron core 502 inside, and the top of the iron core 502 extends to the outer side of the inner frame 302 and is located on the side of the relay plate 4022.

[0041] The relay with increased insulation distance structure of this utility model generates a magnetic field on the inner side of the enameled wire 501 after being energized, which drives the iron core 502 set on its inner side to operate, and drives the relay piece 4022 that is in contact with the iron core 502 to operate.

[0042] In this design, during relay assembly, the insulating cover 301 is first assembled with the base plate 20, followed by the assembly and riveting of the yoke 503 with the iron core 502. The insulating cover 301 and the inner frame 302 have corresponding adhesive grooves at their assembly connection points, forming the first insulating layer through adhesive application. The base plate 20 has holes corresponding to the relay stationary piece 4011 and the relay electric piece 4022, allowing for assembly and connection via insertion. Corresponding fasteners are also designed on the base plate 20 and the outer casing 10 for tight connection with the relay stationary piece 4011 and the relay electric piece 4022.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
