[0018] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0019] like Figures 1 to 3 The diagram shown is a structural schematic of a high-consistency relay spring assembly provided by this utility model. The high-consistency relay spring assembly includes a frame 10, a backing pad 20 disposed on the frame 10, a pair of moving contact assemblies 30 disposed on the backing pad 20, and a fastening assembly 40 fastened to the frame 10. It is conceivable that the high-consistency relay spring assembly also includes other functional structures, such as a swing arm groove, a slide rail, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0020] The frame 10 includes a frame body 11, two buckles 12 respectively disposed on opposite ends of the frame body 11, and two guide posts 13 disposed between the two buckles 12.

[0021] The frame body 11 is accommodated in a relay base (not shown in the figure). The buckle 12 is buckled with the buckle assembly 40 to fix the movable contact assembly 30 to the frame body 11. The guide column 13 is used to mount the abutting pad 20 and connect the movable contact assembly 30.

[0022] The abutting pad 20 is a metal sheet and is once stamped and formed. The abutting pad 20 comprises an abutting body 21 and two pairs of abutting ends 22 arranged on both sides of the abutting body 21. The abutting body 21 is provided with two insertion holes 23 corresponding to the positions of the guide columns 13. The abutting body 21 is inserted on the guide columns 13 through the two insertion holes 23. The two pairs of abutting ends 22 are bent towards the movable contact assembly 30 along the end connected with the abutting body 21, and the free ends of the two pairs of abutting ends 22 are bent towards the frame 10, so that the end faces of the two pairs of abutting ends 22 are in the same horizontal plane.

[0023] The movable contact assembly 30 comprises a connecting plate 31, two movable contacts 32 arranged respectively at both ends of the connecting plate 31, a compensation pad 33 arranged on the end face of the connecting plate 31 away from the movable contacts 32, and a buckle plate 34 buckled in the middle region of the connecting plate 31.

[0024] The connecting plate 31 is provided with a recess 35 in the middle region of each side edge towards the buckle 12, for accommodating the buckle plate 34. The movable contacts 32 are used to abut against the static contacts (not shown in the figure) to connect the current. The connecting plate 31 is provided with two protruding columns 36 spaced apart on the end face away from the movable contacts 32.

[0025] Please refer to Figure 4 The compensation pad 33 comprises a pad body 331, two compensation ends 332 arranged at both ends of the pad body 331, a through hole 333 arranged in the middle region of the pad body 331, and two protruding column holes 334 symmetrically arranged on both sides of the through hole 333. The through hole 333 is used in cooperation with the buckle assembly 40. The two protruding column holes 334 are arranged corresponding to the positions of the two protruding columns 36, and the protruding column holes 334 are sleeved on the protruding columns 36, so as to fix the compensation pad 33 on the connecting plate 31. The compensation ends 332 at both ends are bent towards the abutting pad 20, and the end portions of the two compensation ends 332 are in the same horizontal plane.

[0026] The length of the compensation pad 33 is the same as the length of the abutting pad 20, so that the compensation ends 332 and the abutting ends 22 abut horizontally.

[0027] In actual production, the two ends of the abutting gasket 20 and the compensation gasket 33 will have errors, and are not in the same horizontal plane. Through the mutual abutting of the two ends of the compensation gasket 33 and the abutting gasket 20, and the middle region of the compensation gasket 33 always abutting the middle region of the connecting plate 31, the compensation gasket 33 is bent at the two ends after abutting with the abutting gasket 20, eliminating the error of the abutting gasket 20 produced in production, so as to ensure that the stress point of the connecting plate 31 is always in the middle region, and then the moving contact 32 at the two ends of the connecting plate 31 can abut the static contact (not shown in the figure) at the same time.

[0028] The two ends of the buckle plate 34 are inserted into the groove 35, and the middle region of the compensation gasket 33 is tightly attached to the connecting plate 31, avoiding the middle region of the buckle plate 34 arching after being stressed, affecting the face-to-face abutting of the two ends of the compensation gasket 33 and the two ends of the abutting gasket 20.

[0029] The buckle assembly 40 includes a buckle member 41 covering the moving contact assembly 30 and buckling with the buckle 12, two pins 42 respectively penetrating the buckle member 41 and the two moving contact assemblies 30, and two elastic members 43 respectively sleeving the pins 42 and the guide columns 13.

[0030] The cross section of the buckle member 41 is a groove structure. The buckle member 41 is provided with a clamping port 44 on the corresponding two end faces, and the clamping port 44 corresponds to the position of the buckle 12, so as to buckle the buckle member 41 on the frame 10.

[0031] One end of the pin 42 penetrates the buckle member 41 and the moving contact assembly 30, connecting the buckle member 41 and the moving contact assembly 30 together, increasing the stability after connection, and providing a sleeving fulcrum for the elastic member 43.

[0032] One end of the elastic member 43 is sleeved on the pin 42, and the other end is connected with the guide column 13, so as to be clamped between the abutting gasket 20 and the moving contact assembly 30, so that when the moving contact 32 is excessively pressed, the elastic member 43 can be compressed to absorb the pressure, and keep the moving contact 32 and the static contact (not shown in the figure) in close contact.

[0033] In use, the moving spring assembly is pulled by the magnetic steel assembly and moves towards the static contact, so that the moving contact 32 abuts against the static contact (not shown) to form a circuit. When the moving contact 32 abuts against the static contact, the elastic member 43 is compressed, and the two ends of the abutting pad 20 and the compensation pad 33 are also compressed, so that the two ends of the moving contact 32 are always balanced.

[0034] Compared with the prior art, the moving spring assembly of the relay with high consistency provided by the utility model is provided with a compensation pad 33 between the connecting plate 31 and the abutting pad 20. The two ends of the compensation pad 33 abut against the two ends of the abutting pad 20, the deformation compensation or error elimination of the two components of the compensation pad 33 and the abutting pad 20 after abutting against each other eliminates the error in the manufacturing process of the pad, so that the connecting plate 31 always keeps the middle region under stress, ensures that the two ends of the moving contact 32 are balanced, and keeps consistency when abutting against the static contact, and the structure is simple and convenient to process.

[0035] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement within the utility model spirit covers the claim scope of the utility model.
