Problems solved by technology

[0002] At present, although small low-voltage switches (such as C45 or DZ47 small low-voltage switches) are widely used in household power supply lines, due to their small size and limitations in their own structures, it is difficult to install an electric opening and closing mechanism.
At present, there are also some small low-voltage switches with electric opening and closing functions on the market. The structure has the following two types: (1) The electric opening and closing mechanism is built in the small low-voltage switch housing, that is, the connection with the small low-voltage switch The terminal, operating mechanism, and overload and overcurrent protection mechanism are set in the same housing, and its structure is relatively complicated, which is prone to failure; in addition, due to the current small market for electric opening and closing small low-voltage switches, enterprises produce this integrated type Electric opening and closing small low-voltage switches require a new design of structure, mold and production process, which requires a large investment; (2) The electric opening and closing mechanism is externally placed on the outer wall of the small low-voltage switch housing, such as disclosed in patent document CN201302949Y Air switch controller; the disadvantage of this structure is that the appearance is ugly, and because the C45 type or DZ47 type small low-voltage switch is mainly installed on DIN rail, the reserved installation space has been standardized, and it is generally difficult to meet this external structure. The required space requirements

Embodiment 1）

[0018] Figure 1 to Figure 5 A first embodiment of the invention is shown, in which figure 1 It is a schematic diagram of a three-dimensional structure of the first structure of the present invention; figure 2 yes figure 1 A schematic diagram of the three-dimensional structure of the small low-voltage switch shown when viewed from another angle; image 3 yes figure 1 A schematic diagram of the three-dimensional structure of the electric opening and closing device in the small low-voltage switch shown; Figure 4 yes image 3 A schematic diagram of the three-dimensional structure of the electric opening and closing device when viewed from another angle; Figure 5 yes image 3 An exploded schematic diagram of the electric opening and closing device shown.

[0019] This embodiment is a small low voltage switch, see Figure 1 to Figure 5 As shown, it includes a small low-voltage switch body 1. The small low-voltage switch body includes a housing 11, a manual trigger 12 for...

Embodiment 2）

[0026] Figure 6 It is an exploded schematic view of the electric mechanism in the second structure of the present invention, showing the second specific implementation mode of the present invention.

[0027] This embodiment is basically the same as Embodiment 1, the difference is that the linkage gear assembly in this embodiment only includes the main gear 541, the pin shaft 544 and the two-way clutch 543, and the main gear is directly engaged with the dial wheel; the output gear, the main Both the gear and the thumb wheel are peripheral gears with gear teeth on the entire peripheral outer wall. This embodiment simplifies the structure of the wheel gear, and removes the auxiliary gear on the basis of Embodiment 1. In this embodiment, the reciprocating rotation angle of the dial is controlled by the rotation angle of the motor.

Embodiment 3）

[0029] Figure 7 It is a structural schematic diagram of the linkage gear assembly in the third structure of the present invention, showing the third specific embodiment of the present invention.

[0030] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 7 As shown, the linkage gear assembly includes a main gear 541 fixedly arranged on a pin shaft 544, an auxiliary gear 542 slidably arranged on a pin shaft, a coil 545 arranged on the main gear, and a yoke 546 arranged on the auxiliary gear 1. A return spring 547 for pushing the secondary gear away from the main gear, a ball 548 arranged between the primary gear and the secondary gear; a plurality of contact pins are arranged on the adjoining surface 5411 of the primary gear adjacent to the secondary gear The limit hole 549 is arranged parallel to the axis extension direction, the ball is located at the opening end of the limit hole, each return spring is located in a corresponding limit hol...

Abstract

The invention discloses a small-sized low-voltage switch. The small-sized low-voltage switch comprises a small-sized low-voltage switch body, wherein the small-sized low-voltage switch body comprises a shell, a manual trigger handle which extends out of the shell and is used for switching off and switching on, and a DIN guide rail-type clamping mechanism arranged on the shell; the small-sized low-voltage switch is characterized by further comprising an electric switching-off and switching-on device for driving the manual trigger handle to achieve switching-off and switching-on operations; the electric switching-off and switching-on device comprises an insulating shell, a poking handle extending out of the insulating shell, an electric mechanism for driving the poking handle to achieve reciprocating poking operation, and a DIN guide rail-type clamping part arranged on the insulating shell; the electric switching-off and switching-on device and the small-sized low-voltage switch body are arranged side by side; the poking handle and the manual trigger handle on the small-sized low-voltage switch body are arranged side by side and relatively fixedly; the electric switching-off and switching-on device drives the manual trigger handle to achieve the switching-off and switching-on operations through the poking handle. The small-sized low-voltage switch is relatively convenient to mount and use.
