Preferably, the front end of the lever is provided with a mounting hole for connecting the U-shaped bolt.

Preferably, the red and green color of the red and green indicator is pad printed by ink, or a red and green indicating sheet is formed by matching corresponding red materials and the ink.

Preferably, the fixing shaft and the lever are made of an integral plastic piece or a metal rod piece embedded in a secondary processing mode. The secondary process inlays when needed, and this step is omitted when not needed.

Preferably, a groove is formed in the shell at the assembling position of the PCB wiring terminal. When the alarm work function is not needed, the mounting groove can be blocked by the blocking piece, the outer surface of the outer appearance shell keeps consistent, and the attractiveness of the outer appearance shell is not affected.

Preferably, the micro switch is provided with a mounting boss at the mounting position. When the alarm function is not needed, the boss does not affect other functions.

The utility model discloses two specific shapes have been designed at the different positions of lever ingeniously, cooperate in shell and micro-gap switch respectively, realize multiple functions. The number of the dies is relatively reduced, and the number of parts is also reduced, so that the structure is relatively simple, and the manufacturing cost is reduced. And a detachable baffle is designed on the shell, so that various functions can be skillfully and flexibly matched.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

Referring to fig. 1 to 4, the embodiment of the present invention provides a backup protector with an indicating, alarming, and tripping device for a backup protector product of an SPD. The indicating, alarming and tripping device mainly comprises a handle 1, a U-shaped bolt 2, a lever 3, a microswitch 4, a circuit board 5 and a PCB wiring terminal 6.

The middle part of the handle 1 is hinged and fixed, the handle 1 is connected with the front end of the lever 3 through the U-shaped bolt 2, and the front end of the lever 3 is provided with a mounting hole 304 for connecting the U-shaped bolt 2. The middle part of the lever 3 is hinged and fixed, and a hinge hole 302 is arranged at the hinged part. The top of the lever 3 is provided with a red-green indicator 303, and the rear end of the lever 3 is provided with a fixed shaft 301 for changing the state of the microswitch 4. The microswitch 4 is connected with a PCB wiring terminal 6 through a circuit board 5.

When the protector is connected into the circuit, the handle 1 is clockwise rotated from the I position to the II position, and the power is switched on. Handle 1 and lever 3 are connected through U type bolt 2, and the pivot of lever 3 is on the right side of tie point, therefore handle 1 clockwise turning, can drive lever 3 anticlockwise rotation. Because the fixed shaft 301 and the red and green indicating piece 303 are integrated with the lever 3, the fixed shaft 301 and the red and green indicating piece 303 are driven to rotate together in the rotating process of the handle 1. Because the fixed shaft 301 and the red and green indicating piece 303 are far away from the circle center of the rotating shaft, certain displacement can be formed in the rotating process.

The fixed shaft 301 is on the right side of its rotation axis, and when the lever 3 is rotated counterclockwise, the fixed shaft 301 is displaced upward. The elastic sheet of the micro switch 4 connected with the elastic sheet is driven to move upwards, and the elastic sheet is compressed to change the micro switch 4 from a closed state to an open state. The state is transmitted to the alarm device by the circuit board 5 and the PCB wiring terminal 6.

The red and green indicating member 303 is on the upper side of its rotation axis, and when the lever 3 is rotated counterclockwise, the red and green indicating member 303 is displaced leftward. The top surface of the red and green indicator 303 has two colors, which are left green and right red, and a window is arranged right above the green sheet. After the lever 3 drives the red-green indicating piece 303 to move to the left, the position of the original red piece is changed to the position of the green piece, the window indicates red, danger is warned, and the product is electrified.

When the small current detection part detects that the SPD has faults of power frequency follow current and the like; conducted to the actuator and then opens the circuit. At the moment, the handle 1 rotates anticlockwise, and when the position II rotates to the position I, the switch-off is powered off. The lever 3 is driven to rotate clockwise. At this time, the fixed shaft 301 is displaced downward. The elastic sheet of the micro switch 4 connected with the micro switch is driven to move downwards, and the elastic sheet is released to change the micro switch 4 from an open state to a closed state. The state is transmitted to an alarm device by a circuit board 5 and a PCB wiring terminal 6, so that the alarm device gives an alarm. The red and green indicator 303 is displaced to the right. The position of the original green sheet is shifted to the position of the red sheet. The window indication is green, the product is powered off, and meanwhile, the window indication also represents that the circuit is abnormal and needs to be overhauled.
