Description of the embodiments
The present utility model will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent.
Referring to fig. 1 and 2, a push-button mute micro-switch comprises a base 1, an upper cover 2, a pressing mechanism and a switching mechanism arranged in an inner cavity formed by the base 1 and the upper cover 2, wherein the switching mechanism comprises a contact piece 6 for switching loops, a pressing handle 3 of the pressing mechanism is arranged on the upper cover 2 in a penetrating manner, a mute limiting block 10 is fixedly arranged at the bottom of the upper cover 2, at least two riveting columns 21 are arranged at the upper cover 2, riveting holes 11 corresponding to the positions of the riveting columns 21 are formed in the mute limiting block 10, and the riveting columns 21 at the upper cover 2 can be in two positions and can be arranged in bilateral symmetry as shown in fig. 2. When the silencing limiting block 10 and the upper cover 2 are assembled, the bottom surface of the upper cover 2 is required to be turned upwards, then the riveting holes 11 of the silencing limiting block 10 are aligned with the riveting columns 21 of the upper cover 2, the silencing limiting block 10 is placed at the upper cover 2, and then the riveting columns 21 are riveted in a mechanical riveting mode, so that the silencing limiting block 10 and the upper cover 2 are firmly assembled into a whole, and the silencing limiting block 10 is prevented from falling off from the upper cover 2. The noise reduction limiting block 10 may be a silica gel material or a rubber material. When the noise reduction limiting block 10 is made of silica gel, the hardness range of the material is 80A-90A.
Specifically, the upper cover 2 is provided with a limit mounting groove 22, and the silencing limit block 10 is fixedly arranged at the limit mounting groove 22. The limiting mounting groove 22 of the upper cover 2 can limit the sound-damping limiting block 10, so that the riveting column 21 at the upper cover 2 is positioned at the center of the riveting hole 11 of the sound-damping limiting block 10 when being mounted on the upper cover 2, and the placing position of the sound-damping limiting block 10 at the upper cover 2 is more accurate.
As shown in fig. 1, the upper cover 2 is covered at the cavity opening of the base 1, and the width D of the silencing limiting block 10 is smaller than the internal width W of the cavity opening of the base 1, so that the silencing limiting block 10 is prevented from blocking interference when the upper cover 2 is covered on the base 1, and the assembly fit between the upper cover 2 and the base 1 is ensured.
The pressing mechanism and the switching mechanism are the same as those of the button type micro switch in the background technology, namely the pressing handle 3 pulls the contact piece 6 through the driving fin by using the tension spring 5, the contact piece 6 swings with one end serving as a support and the other end under the action of the tension spring 5, and an elastic clamping piece of a plastic piece 7 assembled on the contact piece 6 is driven to slide and switch between the first electrode 8 and the second electrode 9 in the swinging process, so that the loop switching of the switch is realized. The contact piece 6 contacts with the silencing limiting block 10 when the switching loop swings, soft contact is adopted between the contact piece 6 and the silencing limiting block, the contact piece 6 cannot collide with the upper cover 2 to make sound in the swinging process, and the silencing limiting block is quiet and free of sound in the working process, so that the silencing limiting block is applicable to application environments with high requirements on silencing effects.
The silencing limiting block 10 is provided with the protruding portion 12 used for being in contact with the contact piece 6, the position of the protruding portion 12 is higher than the riveting head formed by the Yu Maojie column 21 after being riveted, and therefore the contact piece 6 can be prevented from being in contact with the riveting head to generate sound when swinging.
