Detailed Description
Example 1:
referring to fig. 1-11, a surge protector with a novel indication mechanism comprises a base 1 and a module unit 2 fixed on the base 1, wherein the base 1 is provided with a first terminal 11 and a second terminal 12, and the first terminal 11 is connected with the second terminal 12 through the module unit 2. The specific structure here is the prior art, and therefore, the detailed description is omitted here.
The module unit 2 is internally provided with a fixing frame 3, a first indicator 4, a second indicator 5, a first reset 6, a first pin 21, an MOV chip 23, a second pin 22 and a first elastic sheet 7.
Be equipped with in the mount 3 and hold chamber 31, MOV chip 23 is located and holds the chamber 31 internal fixation, and MOV chip 23 includes two links 231, and one of them link 231 is the vertical upward extension for be connected with first shell fragment 7, and another link 231 is the side bend, is used for realizing electrical connection with the cooperation of second pin 22.
The first pin 21 and the second pin 22 are respectively located on two sides of the fixing frame 3, and extend out of the module unit 2 vertically downwards, so that the first pin 21 and the second pin 22 realize the electrical connection effect with the first terminal 11 and the second terminal 12.
The fixing frame 3 is provided with a fixing cavity 32, and the fixing cavity 32 is used for fixing the first indicator 4, the second indicator 5 and the first elastic sheet 7. The fixing cavity 32 is located at the uppermost portion of the fixing frame 3, and the connecting end 231 extends vertically upward into the fixing cavity 32. It should be noted that a see-through window is provided at the top end of the fixing cavity 32, through which the two indicators can be viewed.
The first indicator 4 includes an indicating portion 41, a head portion 42, and a fixing portion 43, the fixing portion 43 is horizontally connected to the head portion 42, and the indicating portion 41 is connected to a side surface of the head portion 42 by a vertical connecting portion, and here, in an initial state, the indicating portion 41 is positioned above the second indicator 5. The fixing portion 43 is provided with a second groove 431, the fixing cavity 32 is provided with a first fixing column 321, one end of the first resetting piece 6 abuts against the first fixing column 321, and the other end of the first resetting piece abuts against the second groove 431. When initial state, first piece 6 that resets is the energy storage state, and first piece 6 that resets adopts this kind of fixed setting for the energy storage is more stable, and stability when releasing the energy is higher. The first return member 6 is here a spring.
A first notch 422 is formed in one side of the head 42, the first notch 422 is U-shaped, the first notch 422 faces the inner side of the head 42, a first sliding block 322 is arranged on the side surface of the fixing cavity 32, and the first notch 422 is matched with the first sliding block 322 to form a sliding guide effect of the first indicator 4. The other side of the head 42 is provided with a first protrusion 423, the side of the fixing cavity 32 is provided with a first sliding groove 323, and the first protrusion 423 slides along the first sliding groove 323. The first sliding groove 323 and the first bump 423 are matched to form a double guiding effect, so that the sliding effect of the first indicator 4 is further improved.
The connection point of the first elastic sheet 7 and the connection terminal 231 of the MOV chip is located on the motion track of the head 42, further, a first groove 424 is arranged below the head 42, and the connection terminal 231 of the MOV chip can be embedded into the first groove 424. The first groove 424 is arranged, so that the connection between the first elastic sheet 7 and the connection terminal 231 of the MOV chip is directly cut off. It should be noted here that the head 42 is horizontally moved by the restoring force of the first restoring member 6.
The second indicator 5 is located below the first indicator 4, and the second indicator 5 is located above the first elastic sheet 7, so that the resetting effect of the first elastic sheet 7 cannot be influenced. The second indicator 5 is fixed, and further, the second indicator 5 is integrally provided with the fixing frame 3. The first indicator 4 and the second indicator 5 are preferably indicated by colors, so that the indicating effect is more obvious, and the preferred scheme here is that the first indicator 4 is green, and the second indicator 5 is red, so as to judge whether lightning protection occurs. Under normal conditions, can observe the green state through perspective window, when taking place the thunderbolt, first indicator 4 removes, and the below of perspective window can only be observed the red state this moment, and at this moment, just need change modular unit 2.
The side surface of the fixed frame 3 is provided with a first positioning column 33, and the limiting part 9 is positioned on the side surface of the fixed frame 3 and vertically moves relative to the side surface of the fixed frame 3. One end of the second reset piece 8 is connected with the first positioning column 33, and the other end is connected with the limiting piece 9. The second restoring member 8 is here a tension spring. During initial state, the top of locating part 9 offsets with the lateral wall of first breach 422, and at this moment, the second piece 8 that resets is the energy storage state, because first indicator 4 is the fixed state, so time locating part 9 can't carry out vertical upward movement. After the first indicating member 4 moves, the second resetting member 8 is reset rapidly, so that the limiting member 9 moves vertically upwards, thereby realizing the limiting effect and preventing the first indicating member 4 from moving in the opposite direction. Further, in order to ensure the stable operation of the limiting member 9, a guide sleeve 91 is sleeved on the limiting member 9.
The operating principle is that, in an initial state, the first elastic sheet 7 is bent to limit the movement of the first indicator 4, at the moment, the first reset piece 6 is in an energy storage state, the second reset piece 8 is also in the energy storage state, and the limiting piece 9 abuts against the first indicator 4. When taking place the thunderbolt protection, the low temperature soldering tin of the link 231 of MOV chip is because the electric current is too big, and the high temperature of production makes soldering tin melt, and at this moment, first shell fragment 7 reconversion for link 231 with the MOV chip separates, and simultaneously, because first shell fragment 7 reconversion, the restriction to first indicator 4 has been removed, and at this moment, first piece 6 that resets, makes first indicator 4 quick travel, and the perpendicular upward movement of locating part 9 prevents first indicator 4 reverse direction motion simultaneously. At this time, the first indicator 4 does not block the second indicator 5, thereby achieving an indicating effect. By adopting the structure, the device is simple in arrangement and high in practicability. And when the horizontal motion of first indicator 4, because the energy storage of first piece 6 that resets releases, make first indicator 4 rapid movement, form the air current of a horizontal direction, can directly blow out the electric arc that first shell fragment 7 and MOV chip's link 231 produced, thereby further improve the protection effect, and further move, first indicator 4 directly is located between the two, the isolation effect has been formed, so first indicator 4 not only possesses the instruction function, still possess and cut off the link 231 between the two of first shell fragment 7 and MOV chip.
