Description

Technical Field

[0001] The utility model belongs to the technical field of unidirectional TVS device packaging, and particularly relates to a packaging structure of a unidirectional TVS device. Background Art

[0002] Unidirectional TVS is a voltage stabilizer that is mainly used to protect electronic equipment from overvoltage shocks from power lines. Its working principle is to introduce a well-conducting material into the circuit to absorb the overvoltage shock and then quickly return to normal working conditions. Unidirectional TVS is mainly used to protect positive polarity power lines. It only allows current to pass in one direction, so it is called "unidirectional".

[0003] After production, unidirectional TVS devices need to be packaged, transported and sold. However, the packaging of unidirectional TVS devices on the market is relatively complex, making it difficult for buyers to unpack them after purchase. Furthermore, it is difficult to restore the packaging if they want to continue to store them after unpacking, which is not conducive to buyers' use. Utility Model Content

[0007] Furthermore, the end of the pop-up spring away from the fixed frame initially contacts the bottom of the entry block, and the pop-up spring is in a taut state in the initial state. When the pop-up spring rebounds, it drives the entry block and the closing cover to move upward.

[0008] Furthermore, in the initial state, one end of the arc block away from the pull rod is located inside the slot, and one end of the arc block is stuck in the slot so that the entry block and the closing cover cannot move upward.

[0009] Furthermore, the arc surface of the arc block faces upward, and the depth of the groove is greater than the length of the arc block. When the arc surface of the arc block is squeezed, it will move into the groove, and the arc block can be completely retracted into the groove.

[0010] Furthermore, the fixing frame is in the shape of a Chinese character U as a whole, and an anti-slip grip is provided on the top of the closing cover. The "U"-shaped fixing frame does not affect the removal and replacement of the unidirectional TVS device body, and the anti-slip grip can prevent hand slippage.

Furthermore, the top of the pressure rod is in conflict with the bottom of the entry block in the initial state, and the sealing airbag is in an expanded state in the initial state. When the entry block leaves the pressure rod, the excess air pressure in the sealing airbag will enter the pressure chamber to push the pressure rod to move upward.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a cover body closing pop-up mechanism, so that when the purchaser needs to unpack, he can pull the pull rods on both sides of the packaging box at the same time, and the closing cover will automatically pop up. At this time, the closing cover can be removed to take out the one-way TVS device body in the placement groove. When the purchaser wants to pack again, he only needs to put the one-way TVS device body back into the placement groove, align the bottom entry block of the closing cover with the packaging box and insert it. At this time, the arc block will automatically snap into the card slot to fix the closing cover and cannot be opened to complete the packaging. The use is simple and convenient.

[0014] 2. The utility model is provided with a sealing mechanism, so that when the bottom entry block of the closing cover is aligned with the packaging box for insertion for packaging, the sealing airbag will expand through the cooperation of the pressure rod, the air pressure chamber and other components to improve the sealing of the packaging box, and after unpacking, the sealing airbag will shrink to prevent the subsequent closing cover from being difficult to cover.

At this time, the entry block 3 and the closing cover 2 cannot move upward to complete the packaging. The operation is simple and convenient during unpacking and subsequent repackaging, which is beneficial to the use of the purchaser. When the closing cover 2 is closed for packaging, the entry block 3 will also press the pressure rod 72 downward. The downward movement of the pressure rod 72 will squeeze the air pressure in the air pressure chamber 71 into the sealing air bag 74 through the air pipe 73, causing the sealing air bag 74 to expand and improve the sealing of the packaging box 1. After unpacking, the entry block 3 leaves the pressure rod 72, and the excess air pressure in the sealing air bag 74 will enter the air pressure chamber 71 to push the pressure rod 72 to move upward to restore. At this time, the sealing air bag 74 no longer expands to avoid affecting the entry of the entry block 3 during subsequent repackaging.
