TECHNICAL FIELD

[0001] The utility model relates to electronic component technical field, specifically speaking, relate to a super small micro switch. BACKGROUND

[0002] Micro switch is with small contact point interval and fast moving mechanism, with the switch action of the prescribed stroke and the prescribed force contact mechanism, with the shell cover, its outside has the drive rod a kind of switch, because its switch contact spacing is relatively small, so called micro switch, also called sensitive switch.

[0003] Among them, the super small micro switch is often used in waterproof occasions. This micro switch usually has a rubber sleeve at the position of the button switch to achieve the effect of waterproof movement. The top of the micro switch is provided with a mounting groove to insert the bottom of the rubber sleeve. This structure is not stable enough and is easy to come off, and it is not convenient enough. SUMMARY

[0004] To overcome the shortcomings of the prior art, the utility model provides a super small micro switch with a rubber sleeve that is more tightly fitted.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a super small micro switch, comprising a shell body, a bottom plate, a button rod and a rubber sleeve, the top of the shell body is provided with a movable hole matched with the button rod, the bottom plate is sealingly connected with the bottom of the shell body, further comprising a mounting plate, the bottom of the rubber sleeve is provided with an outwardly arranged mounting outer ring, the mounting plate is provided with a mounting hole with a diameter smaller than the outer diameter of the mounting outer ring, and the mounting plate is connected with the top of the shell body.

[0006] In this way, after the shell body, the bottom plate, the button rod and other internal conventional parts such as the contact piece or the spring are installed, the rubber sleeve can be externally fitted on the button rod to make the head of the rubber sleeve clamped in the groove on the top of the button rod. In this way, the rubber sleeve is preliminarily installed on the micro switch. Then, the mounting plate can be installed from the top of the shell body with its mounting hole aligned with the button rod. After the two are connected, the connection is completed. After the connection, the mounting plate will be pressed on the mounting outer ring at the bottom of the rubber sleeve to clamp it, thereby increasing the stability of the rubber sleeve. The installation is convenient while the stability is ensured. The external clamping will not leak, and the clamping will not increase the installation difficulty.

[0007] Further, the top of the shell body is provided with a connecting claw on each side, the mounting plate is provided with a claw groove corresponding to the connecting claw, and the size of the mounting plate is not greater than the top surface of the shell body.

[0008] With this configuration, the connecting claws on the outer casing will pass through the claw slots on the mounting plate and lock in place. After the claws are set on the top surface, the size of the mounting plate can be set to be smaller, such as the same size as the top surface of the outer casing, reducing its lateral space occupation. When the claws are set on the outer casing, they will not enter the interior of the outer casing, thus avoiding leakage.

[0009] Furthermore, the claw groove is provided through the side wall of its corresponding side.

[0010] With this configuration, the chuck slots will be located at both ends, making machining and installation convenient.

[0011] Furthermore, the top surface of the outer shell is provided with a positioning boss surrounding the movable hole, and the outer diameter of the positioning boss is smaller than the bottom inner diameter of the rubber sleeve.

[0012] With this setup, the positioning boss will initially position the bottom of the rubber sleeve, correct its position, and ensure that the mounting plate can clamp each position of the outer ring after installation, thus ensuring sealing and installation stability.

[0013] Furthermore, the mounting plate has a mounting groove at the mounting hole on one end facing the outer casing. The diameter of the mounting groove is larger than the diameter of the mounting outer ring, and the distance between the mounting groove and the top surface of the outer casing is smaller than the thickness of the mounting outer ring.

[0014] With this configuration, the mounting plate can be more tightly fitted to the top surface of the outer casing after the mounting groove is installed. The mounting groove can completely cover the outer ring of the mounting plate, and since the distance between the mounting groove and the top surface of the outer casing is less than the thickness of the outer ring of the mounting plate, the mounting groove can also have a clamping effect.

[0015] Furthermore, the mounting groove is provided with a pressing protrusion surrounding the mounting hole.

[0016] This design reduces the area of ​​the pressing position by reducing the pressing force, thus achieving a locking effect and providing greater stability than simply pressing.

[0017] Furthermore, the distance between the positioning boss and the mounting hole is less than the wall thickness of the rubber sleeve.

[0018] This configuration allows the positioning boss and the mounting hole to be positioned to provide a further clamping effect, enhancing stability. Attached Figure Description
