Description

Technical Field

[0001] The utility model relates to the technical field of adapters, in particular to an adapter for a notebook computer. Background Art

[0002] A power adapter is also called an external power supply. A power adapter is a power conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as laptops.

[0003] In the prior art, the outer shell of the adapter is generally composed of two parts that are snap-connected, and then glued or ultrasonically welded. This connection method is not only unstable, but also easy to crack when dropped or hit. When disassembling for repair, generally only a flat-blade screwdriver can be used to cut along the snap-connection gap to separate the two parts. This violent disassembly method often causes deformation or damage to the outer shell at the joint. After the adapter is repaired, when the two parts of the outer shell are connected, glue is still needed for bonding, which is extremely inconvenient. Utility Model Content

Compared with traditional violent disassembly, the opening will not be torn or deformed.

[0046] The upper shell 100 and the lower shell 200 are embedded in each other for connection, and the connection between the two is firm. The adjustment rod passes through a plurality of pins and slots, so that the upper shell 100 and the lower shell 200 are kept tight at all places in the length direction, thereby improving the structural stability of the shell, and the gap at the opening of the shell is not easy to crack;

[0047] A reinforcement layer 500 is provided in the shell to improve the strength and impact resistance of the shell. The mesh-structured reinforcement net 501 also improves the puncture resistance of the shell. The adapter is not easily damaged by impact, thus meeting military requirements.
