Description

Technical Field

[0001] The utility model relates to the technical field of micro switches, in particular to a side-type two-pin micro switch. Background Art

[0002] A micro switch is a switch that uses very small force, and applies external mechanical force to the action reed through a transmission element, so that the fixed contact and the moving contact at the end of the switch are quickly connected or disconnected; the current micro switches are divided into normally open micro switches and normally closed micro switches. The normally open micro switch is in the disconnected state when not pressed, and in the contact state when pressed. The normally closed micro switch is in the contact state when not pressed, and in the disconnected state when pressed. The current use of micro switches is based on the on-site needs of users, but in actual practical use, micro switches still expose some problems. The terminals of the micro switches on the market are currently led out from the bottom and can only be used for horizontal assembly, which is difficult to assemble and use from the side. In addition, the current micro switches basically use external mechanical force conduction to adjust the contacts, which can easily cause foreign matter to enter the switch and cause abnormal switch operation.

[0003] In view of the problems exposed during the use of the current micro switch, it is necessary to improve and optimize the structure of the micro switch. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a side-type two-legged micro switch, which has the characteristics of being easy to install and use from the side of the micro switch and effectively preventing foreign matter from entering the interior of the switch.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side-type two-leg micro switch, comprising a base and a cover, wherein a first terminal is embedded in the interior of the base, a spring is embedded at the top of the first terminal, and a second terminal is also embedded in the interior of the first terminal, wherein an end of the spring away from the first terminal contacts an end of the second terminal under its own elastic force, thereby completing an electrical connection between the first terminal and the second terminal, and the ends of the first terminal and the second terminal away from the spring both extend through the side of the base;

[0006] The cover plate is placed on the base to seal the base. A lower pressing piece and a driven head are embedded on the upper surface of the cover plate. A sealing member is provided on the top of the driven head. A rebound assembly is provided on the bottom of the driven head. When the height of the driven head changes, pressure is applied to the spring sheet to separate the spring sheet from the second terminal.

[0007] The sealing component includes a pressing end head arranged at the top of the driven head, the outer wall of the bottom end of the pressing end head is covered with a corrugated rubber sleeve, and the bottom end of the corrugated rubber sleeve is bonded to the upper surface of the cover plate to seal the gap between the driven head and the cover plate.

[0008] As an optimal technical solution for a side-type two-legged micro switch of the utility model, the rebound component includes a corrugated sheet, which is a corrugated circular sheet component. The bottom end of the driven head contacts the center of the corrugated sheet, and the outer edge of the driven head is bonded to the inner wall of the cover plate, thereby sealing the gap between the driven head and the cover plate and allowing the driven head to rebound when not under force.

[0009] As an optimal technical solution for a side-type two-legged micro switch of the present invention, one end of the lower pressing plate is bent so that the lower pressing plate forms an L-shaped component. When the bent end of the lower pressing plate is pressurized, the top of the pressing end head is pressed to cause the driven head to move.

[0010] As an optimal technical solution for a side-type two-legged micro switch of the utility model, the outer wall of the cover plate is also embedded with a rotatable limit clamp, which is a U-shaped component. When the lower pressing piece is pressed down to squeeze the pressing end, the limit clamp can limit the lower pressing piece.

[0011] As an optimal technical solution for a side-type two-legged micro switch of the utility model, the side wall of the distal free end of the lower pressing plate is inwardly converged with a groove, and the closed end of the limit clamp is inwardly converged and can be engaged with the groove on the side of the lower pressing plate, so as to limit and lock the lower pressing plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The micro switch provided in this technical solution has the first terminal and the second terminal arranged on the side of the switch, which can facilitate the side installation and use of the micro switch. The switch is additionally provided with a corrugated rubber sleeve and a corrugated sheet, which can seal the gap between the driven head and the cover plate, so that the driven head maintains the seal of this area when the height changes, effectively preventing debris from passing through the gap area to reach the interior of the switch.

[0014] 2. The technical solution also adds a limit clamp, which can apply pressure to the lower pressure piece when used, and can effectively limit and lock the lower pressure piece. At this time, the lower pressure piece presses the pressing end and the driven head, so that the spring piece is under pressure. At this time, the contacts of the spring piece remain normally open, which is convenient for the staff to change the working mode of the micro switch and adjust the use of the micro switch according to their own needs.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] like Figure 1-3 As shown, the utility model discloses a side-type two-leg micro switch, including a base 1 and a cover plate 4, a first terminal 2 is embedded in the base 1, a spring 11 is embedded at the top of the first terminal 2, and a second terminal 3 is also embedded in the first terminal 2. The end of the spring 11 away from the first terminal 2 contacts the end of the second terminal 3 under its own elastic force, so that the first terminal 2 and the second terminal 3 are electrically connected, and the ends of the first terminal 2 and the second terminal 3 away from the spring 11 both pass through the side of the base 1; the inner walls of the two side walls of the cover plate 4 in the utility model are provided with protrusions, and the two side surfaces of the base 1 are provided with indentations. When the cover plate 4 is set on the base 1, the indentations and the protrusions make the cover plate 4 tightly connected to the base 1.

[0023] The cover plate 4 is placed on the top of the base 1 to seal the base 1. The upper surface of the cover plate 4 is fitted with a lower pressing piece 5 and a driven head 9. A sealing member is provided at the top of the driven head 9, and a rebound assembly is provided at the bottom of the driven head 9. When the height of the driven head 9 changes, pressure is applied to the spring piece 11, so that the spring piece 11 is separated from the second terminal 3.

[0024] The sealing component includes a pressing end 6 arranged at the top of the driven head 9, and the outer wall of the bottom end of the pressing end 6 is provided with a corrugated rubber sleeve 8. The bottom end of the corrugated rubber sleeve 8 is bonded to the upper surface of the cover plate 4 to seal the gap between the driven head 9 and the cover plate 4. The sealing structure effectively prevents foreign matter or water from entering the interior of the switch, thereby improving the stability of the switch.

[0025] Specifically, the rebound component includes a corrugated sheet 10, which is a corrugated circular sheet component. The bottom end of the driven head 9 contacts the center of the corrugated sheet 10, and the outer edge of the driven head 9 is bonded to the inner wall of the cover plate 4. The gap between the driven head 9 and the cover plate 4 is sealed and the driven head 9 rebounds when no force is applied. In this embodiment, the corrugated sheet 10 can be a metal sheet component or not. It only needs to have a certain rebound performance.

[0026] Specifically, one end of the lower pressing piece 5 is bent so that the lower pressing piece 5 forms an L-shaped component. When the bent end of the lower pressing piece 5 is pressed, it can pressurize the top of the pressing end head 6 to displace the driven head 9. In this embodiment.

[0027] Specifically, the outer wall of the cover plate 4 is also embedded with a rotatable limit clip 7, which is a U-shaped component. When the lower pressing plate 5 is pressed down to squeeze the pressing end 6, the limit clip 7 can limit the lower pressing plate 5. The side wall of the distal free end of the lower pressing plate 5 is inwardly converged with a groove, and the closed end of the limit clip 7 is inwardly converged and can be engaged with the groove on the side of the lower pressing plate 5, which is used to limit and lock the lower pressing plate 5. In this embodiment, the above method can be used to maintain the stability of the structure when the limit clip 7 locks the lower pressing plate 5.

[0028] The working principle and usage process of the present invention: The micro switch provided in the technical solution of the present invention has the first terminal 2 and the second terminal 3 arranged on the side of the switch, which can facilitate the side installation and use of the micro switch. A corrugated rubber sleeve 8 and a corrugated sheet 10 are added to the switch to seal the gap between the driven head 9 and the cover plate 4, so that the driven head 9 maintains the sealing of the area when the height changes, effectively preventing debris from reaching the interior of the switch through the gap area.

[0029] When the staff uses the switch, when the limit clamp 7 is not used, the switch is a normally closed switch. At this time, the circuit defaults to being connected. When the circuit needs to be disconnected, the user presses the lower pressure piece 5 to disconnect the switch. When the switch needs to be kept disconnected for a long time, it is only necessary to use the limit clamp 7 to limit the lower pressure piece 5. At this time, the switch remains normally open.

[0030] A corrugated sheet 10 is added to the switch. The corrugated structure of the corrugated sheet 10 can make the driven head 9 exert an upward rebound force on it when it is not under downward pressure, thereby keeping the switch contacts normally closed.

[0031] The present technical solution is also provided with a limit clamp 7, which can apply pressure to the lower pressing piece 5 when in use, and can effectively limit and lock the lower pressing piece 5. At this time, the lower pressing piece 5 applies pressure to the pressing end 6 and the driven head 9, so that the spring piece 11 is subjected to pressure. At this time, the contacts of the spring piece 11 remain normally open, which is convenient for the staff to change the working mode of the micro switch and convenient for the staff to adjust the use of the micro switch according to their own needs.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to be a further limitation of the present invention. All equivalent changes made using the contents of the present invention specification and drawings are within the scope of protection of the present invention.
