Description

Technical Field

[0001] This utility model relates to the technical field of relay bases, specifically to a high-pressure-resistant and deformation-resistant relay base. Background Technology

[0002] As a core control component in power systems and electronic equipment, the relay's base is the core carrier supporting key components such as moving and stationary reeds. It must not only ensure the insulation and isolation performance between each reed, but also have sufficient structural strength to resist external forces and environmental stress deformation during long-term use, while meeting the electrical safety requirements under high-voltage conditions. In existing technologies, relay bases suffer from the following drawbacks: Traditional bases typically have a flat insulating surface, lacking an effective textured design. The creepage distance directly determines the base's withstand voltage rating; a flat insulating surface results in a short creepage distance, making it prone to creepage breakdown under high-voltage conditions, thus failing to meet the requirements of high-voltage applications. Furthermore, existing bases are susceptible to localized deformation under prolonged stress or environmental temperature changes, leading to reed misalignment and consequently, poor relay contact and operational failure, severely impacting equipment reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a high-pressure-resistant and deformation-resistant relay base to overcome the above-mentioned defects in the prior art.

[0005] Preferably, the retaining wall assembly includes a retaining wall and a fixing block. The retaining wall is disposed on the base body and surrounds the insulating plate to form a slot. The fixing block is located in the slot and connected to the insulating plate. The bottom of the slot is provided with an insertion hole.

[0006] Preferably, the second retaining wall assembly includes a second retaining wall, a third retaining wall, a base, and a second fixing block. The second retaining wall is disposed on the base body and connected to the insulating plate. The third retaining wall is disposed on the base body and connected to the second retaining wall. The inner sides of the second and third retaining walls are provided with a base that surrounds the insulating plate to form a slot two. The second fixing block is disposed in the slot two. The bottom of the slot two is provided with a second insertion hole. The base is provided with a first protrusion above the slot two.

[0007] Preferably, the retaining wall assembly three includes a retaining wall four and a fixing block three. The retaining wall four has a "U"-shaped structure and is disposed on the base body. The retaining wall four is connected to the retaining wall one through a connecting wall. The fixing block three is disposed on the base body and located in the retaining wall four. A slot three is formed between the retaining wall four and the fixing block three. The two ends of the fixing block are respectively provided with a protrusion two and a protrusion three.

The retaining wall assembly 3 includes a retaining wall 31 and a fixing block 33. The retaining wall 31 is located on the base body 1 and surrounds the insulating plate 2 to form a slot 32. The slot 32 provides an installation position for the movable spring and ensures that the movable spring will not shift laterally after being inserted. The fixing block 33 has an "L" shaped structure and is located in the slot 32 and connected to the insulating plate 2. The bottom of the slot 32 is provided with a insertion hole 34, which provides a passage for the pin of the movable spring to pass through. Additionally, the base body 1 has a second retaining wall assembly 4 for installing the stationary spring sheet 1 on the other side of the insulating plate 2. The second retaining wall assembly 4 includes a second retaining wall 41, a third retaining wall 42, a base 44, and a second fixing block 45. The second retaining wall 41 is located on the base body 1 and connected to the insulating plate 2. The third retaining wall 42 is located on the base body 1 and connected to the second retaining wall 41. The inner sides of the second retaining wall 41 and the third retaining wall 42 are provided with a base 44 that surrounds the insulating plate 2 to form a second slot 43, thus forming a multi-directional surrounding positioning of the stationary spring sheet 1. The second fixing block 45 is a cuboid structure and is located in the second slot 43. The bottom of the second slot 43 is provided with a second insertion hole 46. The base 44 is provided with a first protrusion 47 above the second slot 43 to press the stationary spring sheet 1. However, the base body 1 has a retaining wall assembly 3 5 on the opposite side of the retaining wall assembly 3 for installing the stationary spring 2. The retaining wall assembly 3 5 includes a retaining wall 4 51 and a fixing block 3 53. The retaining wall 4 51 has a "U" shaped structure and is located on the base body 1. The retaining wall 4 51 is connected to the retaining wall 1 31 by a connecting wall 52. The fixing block 3 53 is located on the base body 1 and is located in the retaining wall 4 51. A slot 3 54 is formed between the retaining wall 4 51 and the fixing block 3 53, which limits the stationary spring 2 by surrounding it on three sides. The two ends of the fixing block are respectively provided with protrusion 2 56 and protrusion 3 57, thereby pressing the stationary spring 2. The bottom of the slot 3 54 is provided with a insertion hole 3 55 below the protrusion 3 57.

[0019] Detailed implementation methods and principles: Installation of the movable spring: Take the movable spring and align its mounting end with the slot 32 formed by the retaining wall 31 and the insulating plate 2. Slowly insert the movable spring into the slot 32. Use the limiting effect of the fixing block 33 to prevent the movable spring from shifting until the mounting end of the movable spring is in contact with the bottom of the slot 32. Adjust the position of the movable spring pin so that the pin passes vertically through the insertion hole 34 at the bottom of the slot 32. Installation of stationary spring 1: Take stationary spring 1 and align it with slot 2 43 formed by base 44 and insulating plate 2. Insert stationary spring 1 into slot 2 43. The displacement of stationary spring 1 is restricted by fixing block 2 45. At the same time, the protrusion 1 47 on the side of base 44 is used to press stationary spring 1 and make the pin of stationary spring 1 pass through the insertion hole 2 46 at the bottom of slot 2 43. Installation of stationary spring 2: Take stationary spring 2 and align it with slot 3 54 formed between retaining wall 4 51 and fixing block 3 53. Insert stationary spring 2 into slot 3 54. The position of stationary spring 2 is defined by the protrusions 2 56 and 3 57 at both ends of fixing block 3 53. At the same time, the surrounding structure of retaining wall 4 51 is used to prevent stationary spring 2 from shifting back and forth. Adjust the pin of stationary spring 2 so that it passes through the insertion hole 3 55 at the bottom of slot 3 54.

[0020] In summary, this application uses three retaining wall components 3, 4, and 5 on the base to form multiple sets of staggered insulation structures. These staggered structures significantly extend the surface creepage distance between the moving spring and the stationary springs 1 and 2 by creating height differences on the insulation surface. At the same time, this multi-component coordinated rigid structure design improves the bending strength of the base body 1. Under long-term stress or high and low temperature cycling, it can effectively resist local deformation, ensure the long-term stability of the spring installation position, and avoid relay failure caused by base deformation.
