Description

Technical Field

[0001] The utility model relates to the technical field of buttons, in particular to a novel self-sealing button. Background Art

[0002] A button is a commonly used control electrical component, often used to connect or disconnect a "control circuit" (in which the current is very small) to achieve the purpose of controlling the operation of a motor or other electrical equipment. The working principle of a button is very simple. For a normally open contact, the circuit is disconnected before the button is pressed. After the button is pressed, the normally open contact is connected and the circuit is connected; for a normally closed contact, the contact is closed before the button is pressed. After the button is pressed, the contact is disconnected and the circuit is disconnected. When using a button for switch operation, the button needs to be kept waterproof in a complex environment.

[0003] Existing waterproof buttons usually use sealing rings for sealing. The sealing effect will gradually deteriorate as the number of times the button is used increases, resulting in reduced sealing of the button and failure to maintain a stable seal. Therefore, it does not meet existing needs. We have proposed a new type of self-sealing button. Utility Model Content

[0004] The purpose of the utility model is to provide a novel self-sealing button to solve the problem in the above background technology that the existing waterproof buttons are usually sealed with sealing rings, and the sealing effect will gradually deteriorate as the number of times the button is used increases, resulting in reduced sealing of the button and inability to maintain stable sealing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new self-sealing button, comprising a plastic shell, a silicone cap is installed on the inner side of the plastic shell, a switch button is installed on the inner side of the silicone cap, a button mounting seat is fixedly installed on the bottom end of the switch button, a sealing ring is provided on the outer side of the bottom end of the silicone cap, a limiting ring is installed on the upper end of the sealing ring, a connecting pressure ring is installed on the outer side of the bottom end of the sealing ring, a compression sleeve is installed on the outer side of the connecting pressure ring, a plurality of positioning blocks are provided on the inner wall of the bottom end of the compression sleeve, a clamping groove is provided on the outer side of the upper end of the compression sleeve, a positioning seat is installed on the lower end surface of the plastic shell, and the positioning seat includes a connecting plate and a plurality of clamping joints.

[0006] Preferably, an elastic filling ring is installed on the upper end surface of the silicone cap, and a waterproof membrane is provided on the upper end surface of the elastic filling ring. The side of the waterproof membrane is bonded and fixed to the plastic shell, and the middle of the waterproof membrane is bonded and fixed to both the silicone cap and the elastic filling ring.

[0007] Preferably, the silicone cap is sleeved and installed on the outer side of the switch button and plugged into the inner side of the connecting pressure ring. The connecting pressure ring and the silicone cap are connected via a sealing ring. The bottom end of the silicone cap is slidably connected to the connecting pressure ring.

[0008] Preferably, the limiting ring and the plastic shell are integrally injection molded, and the upper end of the sealing ring is inserted between the plastic shell and the limiting ring.

[0009] Preferably, the connecting plate is fixed to the plastic shell by screws, the connecting plate and the plurality of card connectors are integrally injection molded, the bottom end of the card connector is inserted into the inner side of the card slot, and the compression sleeve is card-connected and installed with the plurality of card connectors.

[0010] Preferably, a positioning groove is provided on the outer side of the bottom end of the connecting pressure ring, and the positioning block is inserted into the inner side of the positioning groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can effectively avoid the probability of water seepage between the plastic shell and the silicone cap through the waterproof film and the elastic filling ring. The connecting plate is installed by clamping with the compression sleeve through multiple clamping joints, so that the multiple clamping joints drive the compression sleeve to move up and squeeze the sealing ring through the connecting compression ring under the limiting action of the limiting ring, thereby ensuring the close fit between the silicone cap and the sealing ring, and realizing the self-sealing effect of the silicone cap;

[0013] 2. When the silicone cap is pressed, the silicone cap drives the waterproof membrane and the elastic filling ring to deform and press the switch button downward, so that the silicone cap slides vertically relative to the plastic shell and the connecting pressure ring, thereby facilitating the switching operation of the switch button. A positioning groove is provided on the outer side of the bottom end of the connecting pressure ring, and the positioning block is inserted into the inner side of the positioning groove, so that the positioning block can prevent the compression sleeve and the connecting pressure ring from deflecting, thereby maintaining the sealing stability when the sealing ring slides and presses the silicone cap.
