Description

Technical Field

[0001] This utility model relates to the field of button technology, and in particular to a button switch with a waterproof and sealed structure. Background Technology

[0002] A push-button switch is a low-voltage electrical appliance used to connect and disconnect control circuits. It is widely used in electric drive and electrical automatic control systems, serving as a master control device to send control signals to drive contactors, relays, electromagnetic starters, and other equipment.

[0003] Existing push-button switches are typically assembled directly from mechanical structures such as button caps, bodies, contacts, and wiring modules. Some products adopt a modular design, requiring assembly during use. When the button cap is pressed down, a gap often exists between it and the body, allowing moisture, humid air, and dust to easily enter the body, affecting component lifespan and even causing switch failure. To address these issues, the applicant proposes an improved technical solution. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of traditional push-button switch designs and provide a product that improves operational stability and reliability in humid environments and extends service life.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A waterproof and sealed push button switch includes a switch body and a housing fixed thereon. The outer surface of the housing is provided with at least one sealing groove. A protective member is fitted onto the housing. The inner surface of the protective member fits against the outer surface of the housing, and the inner surface of the protective member is provided with a sealing protrusion that cooperates with the sealing groove.

[0007] Preferably, the end of the protective member is provided with a radial flange extending inward in the axial direction, and the flange is in close contact with the edge of the housing.

[0008] Preferably, the end of the flange is provided with an elastic deformation portion extending downward along the axial direction, and the end of the elastic deformation portion is provided with an operating portion extending radially and inward.

[0009] Preferably, the housing has a movable button that can be raised and lowered, located below the operating part.

[0010] Preferably, the protective component is made of an elastic rubber material.

[0011] Beneficial effects:

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention forms a first sealing measure by having a protective component fit into the housing, and a second sealing measure by having a sealing protrusion embedded in a sealing groove. This effectively isolates external moisture, humid air, and dust from intrusion, reduces the risk of internal components being contaminated or oxidized, extends the service life of the switch, and improves its operational stability and reliability in harsh environments such as humidity and dust.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0022] Reference example Figures 1 to 3A waterproof and sealed push button switch includes a switch body 1 and a housing 2 fixed thereon. The outer surface of the housing 2 is provided with at least one sealing groove 21. The housing 2 is fitted with a protective member 3. The inner surface of the protective member 3 is in contact with the outer surface of the housing 2, and the inner surface of the protective member 3 is provided with a sealing protrusion 31 that cooperates with the sealing groove 21. The protective member 3 forms a first sealing measure by fitting the housing 2, and the sealing protrusion 31 is embedded in the sealing groove 21 to form a second sealing measure. This effectively isolates external moisture, humid air and dust from intrusion, reduces the risk of internal components being contaminated or oxidized, extends the service life of the switch, and improves its operational stability and reliability in harsh environments such as humidity and dust.

[0023] It is worth mentioning that the end of the protective component 3 is provided with a radial flange 32 extending inward in the direction of its axis. The flange 32 is in close contact with the edge of the housing 2. The flange 32 enhances the overall sealing performance through surface contact and is one of the components of the multi-layer sealing structure. The radial flange 32 design enables the protective component 3 to form a tight contact with the housing 2 after assembly, reducing the path of external environmental media intrusion. The flange 32 structure also has elastic deformation capability, achieving adaptive fitting under assembly pressure, compensating for manufacturing tolerances, and improving sealing stability.

[0024] It is worth mentioning that the end of the flange 32 is provided with an elastic deformation part 33 extending downward along the axial direction. The end of the elastic deformation part 33 is provided with an operating part 34 extending radially and inward. By pressing down the operating part 34, the elastic deformation part 33 is bent to store energy. After the downward pressure is removed, the elastic deformation part 33 releases energy, causing the operating part 34 to automatically reset. It has both sealing and operating functions, realizing continuous sealing and button 4 triggering in dynamic environments.

[0025] It is worth mentioning that the housing 2 is equipped with a button 4 that can be raised and lowered, and is located below the operating part 34. Through the coordinated action of the flange 32, the elastic deformation part 33, and the operating part 34, a relatively sealed space is constructed, which effectively prevents external moisture, humid air and dust from intruding into the button 4.

[0026] It is worth mentioning that the protective component 3 is made of elastic rubber material. The use of elastic rubber material in the protective component 3 has excellent deformation recovery ability and sealing adaptability, ensuring that it can maintain stable sealing performance under long-term stress and temperature changes, reducing the risk of failure caused by material fatigue, and significantly improving the reliability and service life of the product in harsh environments.

[0027] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
