Problems solved by technology

In order to reduce the noise, the existing technology usually adopts a flat bowl structure sound-absorbing bowl installed between the movable part and the fixed part as a buffer part between the movable part and the fixed part. The impact force energy can only prolong the buffer time by compressing the deformation of the buffer, and the displacement generated by the solid deformation is very limited. Therefore, the time of the moment of collision is very small, which makes the moment of collision very large. Therefore, This sound-absorbing bowl of the prior art has a poor effect of eliminating noise, and there is still relatively large noise

Embodiment 1

[0034] see Figure 1 to Figure 3 As shown, a sound-absorbing bowl of the present invention is arranged between the movable part and the fixed part and is installed on the fixed part. The sound-absorbing bowl 5 is set as an arc-shaped structure and has a horn-shaped opening 51; An abutting portion 54 is provided at one end toward the fixed part, a contact portion 55 is provided at one end toward the movable part, and a buffer portion 53 is set between the contact portion 55 and the mounting portion 54; when the movable part moves toward the fixed part , the movable part is in contact with the contact portion 55 of the sound-absorbing bowl and presses the contact portion 55 against the fixed part, so that the buffer portion 53 of the sound-absorbing bowl is deformed.

[0035] In this embodiment, the thickness of the contact portion 55 is greater than the thickness of the abutting portion 54 and also greater than the thickness of the buffer portion 53 .

[0036] In this embodime...

Embodiment 2

[0042] see Figure 4 As shown, a sound-absorbing bowl of the present invention differs from Embodiment 1 in that the contact portion 55 of the sound-absorbing bowl 5 is arranged on the opening edge corresponding to the trumpet-shaped opening 51, and the abutment portion 54 is arranged on the corresponding At the tip of the trumpet-shaped opening 51.

Embodiment 3

[0044] see Figure 1 to Figure 3 , Figure 5 to Figure 9 As shown, a noise reduction relay of the present invention includes a moving iron core 1, a static iron core 2, a push rod part 3 and a yoke 4; the push rod part 3 includes a push rod 31 and a moving spring mounting seat 32, The push rod 31 is passed through the middle hole 21 of the static iron core 2, one end of the push rod 31 is fixed to the moving iron core 1, and the other end of the push rod 31 is fixed to the moving spring mount 32; the yoke 4 It is fixed in one end face of the static iron core 2, and this end face is facing the moving spring mounting seat 32; The noise reduction bowl 5 as described in Embodiment 1 is used to eliminate the noise when the moving spring mounting seat 32 contacts and collides with the yoke 4, and the abutting portion 54 of the noise reduction bowl 5 is attached to the plate of the yoke 4 noodle.

[0045] A through hole 52 is also provided in the middle of the sound-absorbing bowl...

Abstract

The invention discloses a silencing bowl and a noise reduction relay thereof. The silencing bowl is arranged between a movable part and a fixed part, wherein the silencing bowl is of an arc-shaped structure and comprises a trumpet open cavity; in the silencing bowl, an abutment part is arranged at one end toward the fixed part and a contact part is arranged at one end toward the movable part; a buffer part is arranged between the contact part and the abutment part; and when the movable part moves towards the fixed part, the movable part is in contact with the contact part of the silencing bowl and the contact part is pressed towards the fixed part, so that the buffer part of the silencing bowl deforms. After the structure is adopted, the collision noise caused by impact force instantaneously generated in contact collision between the movable part and the fixed part can be effectively eliminated, so that the target of reducing noise is achieved.

Description

technical field [0001] The invention relates to a sound-absorbing bowl and a noise-reducing relay thereof. Background technique [0002] In the prior art, there is usually a structure in which a movable part moves to a fixed part and contacts, and when the movable part comes into contact with the fixed part, the collision will generate noise, which will affect the user's perceived quality degradation when using the product . For example, in a relay, the relay is usually composed of a magnetic circuit system, a contact system, a driving part, and an installation lead-out part. The magnetic circuit system mainly converts electrical energy into mechanical energy to drive the driving part to move, making the contact system contact, so as to achieve the function of a switch. . The mechanical motion generated by the magnetic circuit system when the electrical energy is converted into mechanical energy moves the pushing part (ie, the movable part), thereby closing (disconnecting)...
