Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a protection device for an integrated circuit chip. Background Art

[0002] The protection device of the integrated circuit chip is the key to ensure that the chip can operate normally in various environments. By adopting appropriate protection measures, the reliability and durability of the chip can be greatly improved. At present, in the prior art, the Chinese patent with the announcement number CN213692010U discloses a protection device for the integrated circuit chip. The device contacts the outer wall of the lap plate through the outer wall of the circuit board, and moves to the rear side with the round rod welded on the rear end of the lap plate, and can also drive the set positioning block to move to the rear side, so that the set positioning block is gradually separated from the positioning groove. When the two are not in contact, the spring can drive the set sliding block to move inside the clamping groove through the restoring action of the spring, and then drive the clamp welded on the lower end of the sliding block to complete the clamping of the outer wall of the circuit board. However, in the actual use of the device, when taking out the circuit board, it is necessary to manually pull the sliding rod upwards so that the positioning block and the positioning groove are re-engaged and connected. This process is relatively time-consuming and labor-intensive. In view of this, we propose a protection device for the integrated circuit chip. Utility Model Content
