Description

Technical Field

[0001] This application relates to the field of switches, and more specifically to a micro switch. Background Technology

[0002] Existing microswitches typically use a single-piece molding process for the pressure plate and the moving block. Two contact plates are fixed to the moving block on both sides, welded together. However, due to manufacturing and assembly errors, the moving block's downward movement distance cannot be effectively guaranteed. Therefore, when the downward movement is too large, the pressure plates on both sides of the moving block will press against the corresponding conductive plates, causing the ends of the conductive plates to bend or deform. This results in the pressure plates failing to effectively contact the corresponding conductive plates during subsequent pressing. Therefore, this structural improvement is needed to address this issue. Thus, there is a need for a microswitch with a simple structure, compact layout, and resistance to deformation of the conductive plates and pressure plates. Summary of the Invention

[0032] refer to Figures 1 to 7 According to a preferred embodiment of the present invention, the micro switch has the following structure: Figure 2 As shown, it includes a housing 10, one side of which has a cavity. The bottom wall of the cavity has two first protrusions 11 and a second protrusion 12. The two first protrusions 11 are arranged opposite each other and spaced apart by a predetermined distance. The second protrusion 12 is located between the two first protrusions 11. The two first protrusions 11 and the second protrusion 12 are integrally formed with the housing 10. In addition, the sides of the two first protrusions 11 that are opposite to each other are spaced apart from the side wall of the cavity to reserve space for the subsequent installation of other components.

[0033] Specifically, the first protrusion 11 and the second protrusion 12 divide the cavity into an upper cavity 101 and a lower cavity 102, and the top of the housing 10 also has an arc groove 103 with an opening, which is connected to the upper cavity 101.

[0034] The micro switch further includes two first conductive plates 20 and two second conductive plates 30. The two first conductive plates 20 are respectively disposed on the opposite sides of the two first protrusions 11, and the two second conductive plates 30 are disposed on the opposite sides of the two first protrusions 11, and located on both sides of the second protrusion 12. It should also be noted that the first conductive plates 20 are concave plates, and the second conductive plates 30 are Z-shaped plates. Furthermore, one end of each of the first conductive plates 20 and the second conductive plates 30 is located in the upper cavity 101, and the other end is located in the lower cavity 102. Additionally, each of the two first protrusions 11 and the second protrusions 12 has a baffle 100 on the side facing the lower cavity 102. The three baffles 100, the two first conductive plates 20, and the second conductive plates 30 are arranged alternately.

[0035] It should also be noted that the end of the first conductive plate 20 placed in the upper cavity 101 is spaced apart from the end of the second conductive plate 30 placed in the upper cavity 101 by a predetermined distance, that is, the gap between the first conductive plate 20 and the second conductive plate 30 is set to reserve space for the installation of subsequent components.

[0036] Specifically, the micro switch further includes a moving component 40, which is located in the middle section of the upper cavity 101. In the initial state, both ends of the moving component 40 are connected to two second conductive plates 30, respectively. Conversely, when the moving component 40 moves closer to the lower cavity 102, both ends of the moving component 40 contact the two first conductive plates 20, respectively. That is, by moving up and down, either the two first conductive plates 20 or the two second conductive plates 30 are energized.

[0037] Specifically, the movable component 40 includes a movable block 41, which is positioned in the middle section of the upper cavity 101. The top of the movable block 41 has a pressing portion 411, which passes through the arc groove 103 and is positioned externally. Furthermore, one side of the movable block 41 also has a mounting groove 401, which penetrates the movable block 41. A third protrusion 412 is also present on the wall surface forming the mounting groove 401 and near the pressing portion 411. Both sides of the third protrusion 412 have a first connecting portion 413.

[0038] Furthermore, the moving component 40 also includes a pressure plate 42, the middle section of which has a groove 4201. Each side of the groove 4201 has a fourth protrusion 421, which is offset from the first connecting portion 413. Specifically, as shown... Figure 2 In the initial state shown in Figure 4, both fourth protrusions 421 are located below the first connecting portion 413. Conversely, when the moving block 41 moves downward, the pressure plate 42 moves upward, at which point the two fourth protrusions 421 are located above the first connecting portion 413. The above-described movement is achieved using springs; that is, the moving assembly 40 also includes two first elastic members (not shown in the figure). One end of each first elastic member engages with one of the two first connecting portions 413, and the other end of each first elastic member is connected to one of the two fourth protrusions 421. In other words, the springs in the initial position are inclined.

[0039] Furthermore, the moving component 40 also includes a second elastic member (not shown in the figure), and the bottom of the moving block 41 has a second connecting portion 414, and the top of the second protrusion 12 has an open cavity 1201. The bottom of the moving block 41 is placed in the cavity 1201 and spaced a predetermined distance from the bottom wall forming the cavity 1201. One end of the second elastic member is connected to the second connecting portion 414, and the other end abuts against the bottom wall forming the cavity 1201. Specifically, to limit the position of the second elastic member, a limiting groove is provided on the bottom wall forming the cavity 1201, and the end of the second elastic member can be disposed in the limiting groove.

[0040] It should also be noted that the pressure plate 42 has two first contact portions 422 on the side near the arc groove 103, with each first contact portion 422 located near both ends of the pressure plate 42. Furthermore, the pressure plate 42 has two second contact portions 423 on the side near the lower cavity 102, also located near both ends of the pressure plate 42. The two first contact portions 422 and the two second contact portions 423 correspond one-to-one. Specifically, both the first contact portions 422 and the second contact portions 423 are semi-cylindrical structures. Additionally, it should be noted that the ends of the first conductive plate 20 and the second conductive plate 30, both located within the upper cavity 101, each have two bent portions 200, and these two bent portions 200 together form a V-shaped positioning groove. Specifically, the two curved portions 200 of the first conductive plate 20 extend away from the second conductive plate 30, and the two curved portions 200 of the second conductive plate 30 extend away from the first conductive plate 20. Those skilled in the art should understand that, initially, the two second contact portions 423 are in contact with the corresponding two curved portions 200 of the two second conductive plates 30, at which point the two second conductive plates 30 are energized. Conversely, when the moving block 41 moves downward (the pressing portion 411 is subjected to an external force), the two first elastic members apply an upward force to the pressure plate 42, causing the pressure plate 42 to move upward a predetermined distance. At this time, the two first contact portions 422 of the pressure plate 42 contact the corresponding two curved portions 200 of the two first conductive plates 20, at which point the two first conductive plates 20 are energized, and the second elastic members are compressed. When the pressing portion 411 is no longer subjected to an external force, the moving block 41 is reset by the second elastic members.

[0041] Additionally, it should be noted that the micro switch also includes a cover plate 50, which is fixed to the side of the housing where the cavity is located. The first conductive plate, the second conductive plate, the first protrusion, and the second protrusion all cooperate with the cover plate 50. Furthermore, the cover plate 50 has an insertion part 51 and a fifth protrusion 52 on the side near the cavity. The insertion part 51 is located at the top of the cover plate 50 and passes through the opening of the arc groove 103 to define the position of the pressing part 411. The fifth protrusion 52 is located on the lower side of the moving block 41 and is spaced at a predetermined distance. That is, the fifth protrusion 52 is configured to limit the downward movement distance of the moving block 41.

[0042] In summary, the micro switch described in the embodiments of this application is explained, which provides advantages such as simple structure, compact layout, and non-deformable conductive plate and pressure plate.

[0043] It is worth mentioning that, in the embodiments of this application, the micro switch has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the micro switch provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
