Description

Technical Field

[0001] This utility model relates to the field of switch technology, and more specifically to a sealed and waterproof switch. Background Technology

[0002] A push-button switch is a circuit switching switch that uses a push-button spring or similar mechanism to make the moving contact and stationary contact make contact to connect or disconnect the circuit. Push-button switches are widely used in various control electrical appliances to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] For push-button switches, they are typically installed on the controller panel using threads or similar methods. However, existing panel thicknesses vary, making it inconvenient to install push-button switches of a single specification. Additionally, the protruding conductive strip of the push-button switch requires waterproofing. Current solutions address these issues by producing push-button switches of different lengths to accommodate varying panel thicknesses. Waterproofing is achieved by using a sleeve around the conductive strip followed by internal glue filling. While these methods solve the problems to some extent, the availability of various push-button switch specifications inevitably increases production costs such as molds. Furthermore, the simple sleeve and glue sealing lacks sufficient strength; under external impact, the sleeve joint is prone to breakage, leading to seal failure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a sealed and waterproof switch that can be easily adapted to different panel thicknesses, while improving structural strength and sealing performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealed and waterproof switch, comprising a switch base and a button portion located on its top, wherein the switch base is externally threaded with an outer sleeve, the upper end of the outer sleeve abutting against the button portion, and the lower end extending and enclosing the switch base inside it; the outer sleeve is filled with a waterproof sealing material.

[0006] The present invention is further configured such that: the outer wall of the outer sleeve is provided with mounting threads for connecting with external equipment.

[0007] The present invention is further configured such that: the button part includes a retaining ring with a diameter larger than that of the switch base and the outer sleeve, and the upper end of the outer sleeve abuts against the lower surface of the retaining ring.

[0008] The present invention is further configured such that the side wall of the switch base abuts against the inner wall of the outer sleeve.

[0009] The present invention is further configured such that: the side wall of the switch base is provided with a support section and an external threaded portion, and the inner wall of the outer sleeve is provided with an abutment section and an internal threaded portion; when the external threaded portion and the internal threaded portion are engaged, the support section and the abutment section cooperate.

[0010] The present invention is further configured such that the support section and the abutment section are disposed above the external thread and the internal thread.

[0011] The present invention is further configured such that: the switch base is internally provided with a circuit module, the circuit module including a button and at least a pair of conductive plates, the button being slidably engaged with the button part, and when the button is pressed down, the pair of conductive plates are turned on.

[0012] The present invention is further configured such that: the circuit module includes an LED bead, and the pins of the LED bead and the pins of the conductive sheet both extend from the bottom of the switch base and extend through wires to the outside of the outer sleeve.

[0013] The present invention is further provided with a sealing ring at the position where the outer sleeve and the button part abut.

[0014] The present invention is further configured such that a gap is left below the external thread portion and the internal thread portion for the filling of waterproof sealing material.

[0015] In summary, this utility model has the following beneficial effects: 1. This utility model is provided with an outer sleeve and an installation thread on the outer sleeve. The length of the switch base is extended by the outer sleeve, so that the switch can be adapted to different panel thicknesses without changing the length of the switch base, which is more versatile and lower in cost.

[0016] 2. The outer sleeve also serves as a container for the pouring of waterproof sealing material, thereby protecting the internal pins and wire connections and ensuring the seal.

[0017] 3. The outer sleeve and the switch base are connected by threads, and the upper end of the outer sleeve extends upward and abuts the bottom of the button. Thus, the outer sleeve encloses the entire switch base, rather than simply covering the bottom of the switch base. Therefore, when subjected to external impact, the outer sleeve can share the load with the switch base and will not break at the joint as in existing technologies. It has higher strength and the sealing effect is less likely to fail. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a sealed and waterproof switch, such as Figure 1-3 As shown, the device includes a switch base 1 and a button portion 2 located on top of it. An outer sleeve 3 is threadedly connected to the outside of the switch base 1. The upper end of the outer sleeve 3 abuts against the button portion 2, and the lower end extends to enclose the switch base 1 within it. A waterproof sealing material 8 is poured into the inner part of the outer sleeve 3. Through this structure, the switch base 1 is completely enclosed by the outer sleeve 3, with the upper end of the outer sleeve 3 extending directly to the button portion 2, thus forming a stable connection between the outer sleeve 3 and the switch base 1. At this point, pouring a waterproof sealing material such as epoxy resin can form a stable sealed connection, resulting in high structural strength and good waterproof performance.

[0024] Furthermore, the outer wall of the outer sleeve 3 is provided with mounting threads 303 for connecting with external equipment. The mounting threads 303 are used to connect with the panel of the external equipment. The mounting threads 303 cover the entire outer wall of the outer sleeve 3. At the same time, the length of the outer sleeve 3 can be flexibly set and adjusted to adapt to panels of different thicknesses. Compared with existing technologies that change the overall length of the waterproof switch, the hollow internal structure of the outer sleeve 3 makes the structure very simple, thus making the length adjustment more convenient and cost-effective.

[0025] Furthermore, the button part 2 includes a retaining ring 201 with a diameter larger than that of the switch base 1 and the outer sleeve 3, and the upper end of the outer sleeve 2 abuts against the lower surface of the retaining ring 201. Simultaneously, a sealing ring can be provided at the position where the outer sleeve 3 and the button part 2 abut. Through the above structure, the upper end of the outer sleeve 3 specifically abuts against the retaining ring 201 of the button part 2. The retaining ring 201 has a circumferentially protruding structure, which can form a stepped surface, thereby improving the sealing performance. After normal installation, the retaining ring 201 just abuts against the surface of the external device panel, and the sealing ring can be squeezed between the external device surface and the retaining ring 201, further improving the sealing at the abutment position.

[0026] Furthermore, to ensure the strength of the switch base 1 and the outer sleeve 3 against external impacts, the side wall of the switch base 1 abuts against the inner wall of the outer sleeve 3. That is, the outer sleeve 3 and the switch base 1 are tightly fitted together. When the outer sleeve 3 is impacted, the switch base 1 can jointly bear the external force. Simultaneously, the outer sleeve 3 extends upwards to the retaining ring 201, making this embodiment less prone to breakage and sealing failure compared to the traditional sleeve simply being fitted under the switch base 1. It offers higher strength and better sealing performance.

[0027] Specifically, the side wall of the switch base 1 is provided with a support section 101 and an external threaded portion 102, and the inner wall of the outer sleeve 3 is provided with an abutment section 301 and an internal threaded portion 302. When the external threaded portion 102 and the internal threaded portion 302 are engaged, the support section 101 and the abutment section 301 cooperate. The internal threaded portion and the external threaded portion are responsible for the meshing connection, while the support section 101 and the abutment section 301 are responsible for the tight fit and impact resistance during the abutment. Furthermore, the support section 101 and the abutment section 301 are positioned above the external threaded portion 102 and the internal threaded portion 302. Through the above arrangement, the lower part of the outer sleeve 3 and the switch base 1 are fixed by glue, the upper part is tightly fitted by the support section 101 and the abutment section 301, and the middle is connected by threads. Thus, when the outer sleeve 3 is subjected to external force, a stable fit can be formed at the upper, middle, and lower positions, resulting in good overall strength.

[0028] Furthermore, the switch base 1 is internally equipped with a circuit module, which includes a button 4 and at least one pair of conductive plates 5. The button 4 slides with the button part 2, and when the button 4 is pressed down, the pair of conductive plates 5 are energized. Simultaneously, the circuit module includes an LED 6, the leads of which extend from the bottom of the switch base 1 and through wires to the outside of the outer sleeve 3. With the above structure, the conductive plates and the button are the basic functional components, similar to existing technologies. In this embodiment, the LED 6 is used to form a light indicator (the top cover of the corresponding button 4 is made of a semi-transparent material), helping the operator to know the current on / off status of the switch. Moreover, since the length of the switch base 1 does not need to be adjusted when adapting to panels of different thicknesses, the distance between the LED 6 and the top button surface remains consistent, resulting in good lighting effects. Existing technologies often require increasing the length of the switch base for thicker panels, thus increasing the distance between the LED and the button surface and weakening the lighting effect. This embodiment does not have this issue, making it more convenient and reliable.

[0029] Furthermore, during installation, a gap 9 is left below the external threaded portion 102 and the internal threaded portion 302 for the waterproof sealant to be poured in. Specifically, the external threaded portion 102 and the internal threaded portion 302 have different numbers of threads, resulting in a thicker screw-on section with a gap at the bottom. This gap 9 allows the waterproof sealant 8 to flow into it during the filling process. After the material cools and solidifies, a stronger connection is formed at this gap 9, resulting in better sealing.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
