Description

Technical Field

[0001] The utility model relates to the technical field of relays, and more specifically to a movable reed assembly of a small-sized reverse suction structure relay. Background Art

[0002] The moving reed is a common accessory in relay devices, and is often used in structures such as the on-off control of relays. The moving reeds used in positive suction relays and negative suction relays are different. For example, a negative suction snap-on relay with patent publication number CN213340231U uses expansion rivets for riveting, and is installed and fixed with buckle ears and yoke irons on both sides of the moving reed. The two sides of this moving reed are only connected by buckle ears, which can easily cause the buckle ears to fall out during transportation due to environmental factors such as vibration and shaking, making the connection between the moving reed and the yoke iron unstable, resulting in failure to work normally. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a movable reed assembly of a small-sized reverse suction structure relay to solve the problems in the above-mentioned background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions: a moving reed assembly of a small reverse suction structure relay, comprising: a moving contact, a mounting plate, a support plate, and an L-shaped elastic plate; one end of the L-shaped elastic plate is fixedly connected to the mounting plate, and the other end is fixedly connected to the support plate; an elastic contact plate is provided at one end of the mounting plate away from the L-shaped elastic plate; the moving contact is provided on the elastic contact plate; a guide reed plate is provided at one end of the support plate; elastic buckles are provided on both sides of the support plate; the two elastic buckles are symmetrically arranged; and a reverse buckle is provided on the elastic buckle to prevent the elastic buckle from falling out.

[0005] Optionally, one end of the elastic contact plate away from the moving contact is bent to form a Z-shaped bending portion.

[0006] Optionally, the guide spring plate is a V-shaped structure.

[0007] Optionally, U-shaped notches are symmetrically arranged on both sides of one end of the elastic contact plate away from the moving contact.

[0008] Optionally, at least one first mounting hole is formed on the support plate.

[0009] Optionally, at least one second mounting hole is formed on the mounting plate.

[0010] Optionally, the mounting plate, the supporting plate, the L-shaped elastic plate, the elastic buckle and the reverse buckle are integrally formed.

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. Based on the design of the original buckle ear structure, the utility model adds a reverse buckle to further improve the connection stability of the elastic buckle, so that the elastic buckle will not fall out under environmental factors such as vibration, shaking, etc., causing the dynamic spring to dislocate.

[0013] 2. A Z-shaped bend is set at the connection of the elastic contact plate, so that the initial height of the contact can be adjusted during the debugging process to make it more in line with actual usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The utility model provides a movable reed assembly of a small reverse suction structure relay, such as Figure 1 As shown, it includes: a moving contact 11, a mounting plate 13, a support plate 12, and an L-shaped elastic plate 14; one end of the L-shaped elastic plate 14 is fixedly connected to the mounting plate 13, and the other end is fixedly connected to the support plate 12; an elastic contact plate 15 is provided at one end of the mounting plate 13 away from the L-shaped elastic plate 14; the moving contact 11 is provided on the elastic contact plate 15; a guide spring plate 18 is provided at one end of the support plate 12; elastic buckles 16 are provided on both sides of the support plate 12; the two elastic buckles 16 are symmetrically arranged; and a reverse buckle for preventing the elastic buckle 16 from falling out is provided on the elastic buckle 16.

[0023] Specifically, when the movable spring and the yoke are fixedly connected and positioned, a reverse buckle 17 is added to further improve the connection stability of the buckle ear so that the buckle ear will not fall out under environmental factors such as vibration, shaking, etc., causing the movable spring and the yoke to be dislocated.

[0024] Specifically, in this embodiment, the guide spring plate 18 is formed by dividing a part of the support plate 12, the L-shaped elastic plate 14 and the mounting plate 13. In this way, the guide spring plate is located on one end of the support plate 12 close to the L-shaped elastic plate 14. This setting can effectively reduce the material consumption in the production process and save a certain degree of material.

[0025] Furthermore, one end of the elastic contact plate 15 away from the movable contact 11 is bent to form a Z-shaped bending portion.

[0026] Specifically, the design of the Z-shaped bending portion 151 allows the height and position of the moving contact 11 to be fine-tuned after the moving spring is installed to better meet the actual usage requirements of the scene.

[0027] Furthermore, the guide spring plate 18 is a V-shaped structure.

[0028] Specifically, the guide spring plate 18 plays a role in signal transmission. At the same time, the V-shaped setting can also play a guiding role to a certain extent, which facilitates the positioning and installation of the moving spring on the relay.

[0029] Furthermore, U-shaped notches 152 are symmetrically provided on both sides of one end of the elastic contact plate 15 away from the moving contact 11 .

[0030] Specifically, U-shaped notches 152 are provided on both sides of the elastic contact plate 15 to reduce the degree of interference of the mounting plate 13 on the elastic contact plate 15 when it bounces, so as to facilitate the travel of the elastic contact plate 15 .

[0031] Furthermore, at least one first mounting hole 121 is defined on the support plate 12 .

[0032] Specifically, a first mounting hole 121 is provided on the support plate 12 on the movable spring sheet. When the support plate 12 and the armature are connected, they are installed by riveting and expansion in the first mounting hole 121. This installation method is more stable and reliable, and is convenient for positioning and installation.

[0033] Furthermore, at least one second mounting hole 131 is defined on the mounting plate 13 .

[0034] Specifically, a second mounting hole 131 is provided on the mounting plate 13 on the movable spring piece. When the mounting plate 13 and the armature are connected, they are installed by riveting and expansion in the second mounting hole 131. This installation method is more stable and reliable, and is convenient for positioning and installation.

[0035] Furthermore, the mounting plate 13, the supporting plate 12, the L-shaped elastic plate 14, the elastic buckle 16 and the reverse buckle 17 are integrally formed.

[0036] Specifically, the one-piece structural design improves the structural strength of the movable spring and further increases the service life of the movable spring.

[0037] The utility model provides a movable spring assembly of a small reverse suction structure relay, which is provided with a reverse buckle 17, so that the connection stability of the elastic buckle 16 is further improved, so that the elastic buckle 16 will not fall out under environmental factors such as vibration, shaking, etc., causing the movable spring to dislocate.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
