Description

Technical Field

[0001] This utility model relates to the field of micro switch technology, specifically a sliding waterproof micro switch structure. Background Technology

[0002] Currently, the micro switches used in the industry employ a momentary up-and-down swing structure, which produces noise during switching. Existing micro switch waterproof structures at the button and sealing ring positions generally use a single tight fit and adhesive structure for protection. This type of solution is costly and has unsatisfactory waterproofing effects. Similar micro switches on the market use a suspended plastic-coated method for the bend in the pin seat slot, and the contact riveting uses a straight-line riveting solution. This type of solution has problems with inaccurate positioning and weak strength in the terminal slot size and structure, and the contact riveting contact ... Utility Model Content

[0003] This invention provides a sliding waterproof micro switch structure, which can solve the problem of noise during switching caused by the instantaneous up-and-down swing structure of existing sliding micro switches.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding waterproof micro switch structure, including a pin holder assembly. A rubber shell is installed on the upper side of the pin holder assembly. A first conductive pin, a second conductive pin, and a third conductive pin are arranged side by side through the pin holder assembly. The upper end of the second conductive pin is located below the upper end of the third conductive pin. Positioning seats are provided on both sides of the second and third conductive pins on the upper side of the pin holder assembly. A conductive clip is slidably fitted between the first and second conductive pins. A button is provided on the upper end of the rubber shell. A spring is installed between the lower end of the button and the pin holder assembly. The lower end of the button is connected to the conductive clip. A handle with one end hinged to the rubber shell is installed on the upper side of the rubber shell. The surfaces of the first and second conductive pins can be cleaned by raising and lowering the conductive clip, which can effectively avoid the problem of non-conductivity caused by foreign objects inside the switch. Moreover, the noise is relatively low. The positioning seats can effectively fix the second and third conductive pins, making the up-and-down sliding of the conductive clip smooth and stable, reducing friction and noise.

[0005] Preferably, a sealing sleeve is provided on the outer side of the press, the upper end of the sealing sleeve is engaged with a groove around the outer side of the press, and the lower edge of the sealing sleeve is engaged with a slot at the upper end of the rubber shell. The gap between the press and the rubber shell is sealed by the sealing sleeve, and the sealing sleeve is fixed by the groove and the slot, which is relatively firm.

[0006] Preferably, the groove on the pusher and the slot on the rubber shell are both provided with triangular ribs. The ribs are in contact with the sealing sleeve. By providing triangular ribs, the sealing and firmness of the installation at both ends of the sealing sleeve can be improved.

[0007] Preferably, the conductive clip includes a central base and clip groups disposed on both sides of the central base. The two clip groups clamp the first conductive needle and the second conductive needle respectively. As the conductive clip rises and falls, one of the clip groups contacts the second conductive needle and the third conductive needle in sequence. The central base can be firmly connected to the button. The clip groups can clamp the first conductive needle and the second conductive needle from front to back, which can ensure the conductivity stability of the conductive clip.

[0008] Preferably, the push button includes a column passing through the top of the rubber shell and a connecting seat located at the lower end of the column. The connecting seat extends to one side and is connected to the conductive clip. The connecting seat can stably install the conductive clip. At the same time, the lower end of the column is connected to a spring to ensure the smooth lifting and lowering of the push button.

[0009] Preferably, the connecting seat has a clearance groove in the middle and at least one guide groove on the outer side wall of the connecting seat. The guide groove matches the inner side wall of the housing to guide the lifting and lowering of the connecting seat. The clearance groove allows the first conductive needle to pass through.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] With a simple structure, the surfaces of the first and second conductive pins can be cleaned by raising and lowering the conductive clip, effectively preventing non-conductivity problems caused by foreign objects inside the switch. Moreover, the noise is relatively low.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-7 As shown, in this embodiment, to solve the problem of noise during switching of existing sliding microswitches that use a momentary up-and-down swinging structure, a sliding waterproof microswitch structure is provided. This structure includes a pin holder assembly 6, with a rubber shell 4 mounted on its upper side. A first conductive pin 61, a second conductive pin 62, and a third conductive pin 63 are arranged side-by-side on the pin holder assembly 6. The upper end of the second conductive pin 62 is located below the upper end of the third conductive pin 63. Positioning seats 65 are provided on the upper side of the pin holder assembly 6, located on both sides of the second and third conductive pins 62. The first conductive pin 61 and the second conductive pin 62 slide up and down together. The device is equipped with a conductive clip 5. A button 3 is provided on the upper end of the housing 4. A spring 7 is installed between the lower end of the button 3 and the needle seat assembly 6. The lower end of the button 3 is connected to the conductive clip 5. A handle 1 with one end hinged to the housing 4 is installed on the upper side of the housing 4. The surface of the first conductive needle 61 and the second conductive needle 62 can be cleaned by raising and lowering the conductive clip 5. This can effectively prevent the switch from not conducting due to foreign objects inside. Moreover, the noise is relatively low. The positioning seat 65 can effectively fix the second conductive needle 62 and the third conductive needle 63, so that the up and down sliding of the conductive clip 5 is relatively smooth and stable, reducing friction and noise.

[0023] Specifically, the needle holder assembly 6 is made of plastic material. During injection molding, the first conductive needle 61, the second conductive needle 62, and the third conductive needle 63 are wrapped and fixed together. When the button 3 is pressed, the conductive clip 5 is driven to move up and down along the first conductive needle 61 and the second conductive needle 62, thereby switching the conduction between the second conductive needle 62 and the third conductive needle 63. The spring 7 can reset the conductive clip 5 and the button 3.

[0024] The handle 1 is easy to press. Press the button 3 down. The operation is simple. One end of the handle 1 is inserted into the slot on the upper side of the housing 4.

[0025] In this embodiment, as Figure 1-4 As shown, a sealing sleeve 2 is fitted around the outer side of the push button 3. The upper end of the sealing sleeve 2 engages with a groove 23 around the outer side of the push button 3, and the lower edge of the sealing sleeve 2 engages with a slot 22 at the upper end of the rubber shell 4. The sealing sleeve 2 seals the gap between the push button 3 and the rubber shell 4. The sealing sleeve 2 is fixed firmly by the groove 23 and the slot 22. When the lower end of the sealing sleeve 2 is engaged in the slot 22, a riveting part can be provided on the rubber shell 4 to press and fix the lower edge of the sealing sleeve 2. At the same time, both the groove 23 on the push button 3 and the slot 22 on the rubber shell 4 are provided with triangular ribs 21 inside. The ribs 21 are in contact with the sealing sleeve 2. The triangular ribs 21 can improve the sealing and firmness of the installation at both ends of the sealing sleeve 2. The ribs 21 can be set on the side wall of the groove 23 or the bottom of the slot 22, and can contact the sealing sleeve 2.

[0026] In this embodiment, as Figure 6 As shown, the conductive clip 5 includes a central base 52 and clip groups 51 disposed on both sides of the central base 52. The two clip groups 51 respectively clamp the first conductive pin 61 and the second conductive pin 62. As the conductive clip 5 rises and falls, one of the clip groups 51 contacts the second conductive pin 62 and the third conductive pin 63 in sequence. The central base 52 can be firmly connected to the button 3. The clip groups 51 can clamp the first conductive pin 61 and the second conductive pin 62 from front to back, which can ensure the conductivity stability of the conductive clip 5. The clip group 51 includes two clips, which are 7-shaped and have an R-angle at the top to reduce friction and maintain conductivity.

[0027] In this embodiment, as Figure 7As shown, the push button 3 includes a column 31 passing through the top of the housing 4 and a connecting seat 34 located at the lower end of the column 31. The connecting seat 34 extends to one side and is connected to the conductive clip 5. The connecting seat 34 can stably install the conductive clip 5. At the same time, the lower end of the column 31 is connected to the spring 7 to ensure the smooth lifting and lowering of the push button 3. The connecting seat 34 has a clearance groove 33 in the middle and at least two guide grooves 32 on the outer side wall of the connecting seat 34. The guide grooves 32 match the inner side wall of the housing 4 to guide the lifting and lowering of the connecting seat 34. The clearance groove 33 allows the first conductive needle 61 to pass through.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
