Description

A travel adapter TECHNICAL FIELD

[0001] The present application relates to a travel adapter. BACKGROUND

[0002] Due to the different plug and socket specifications in different countries, they cannot be used universally. If the plug needs to be inserted into the socket with unmatched specifications, a travel adapter is needed. The travel adapter is an adapter tool. When used, the travel adapter is inserted into the target socket, and then the target plug is inserted into the socket hole matched with it on the travel adapter to achieve conversion. The emergence of the travel adapter improves the convenience of people's life outside, especially when traveling across countries, without worrying about the trouble caused by the mismatch between the plug of the electronic equipment carried and the local power socket.

[0003] However, in the commonly used travel adapter with British plug pins and European plug pins, the European plug pins and the British plug pins will separately occupy a certain space inside the travel adapter.

[0052] In summary, the travel converter has the characteristics of compact structure, the first fire wire pin and the first zero line pin of the British standard plug are arranged on the first side of the European standard sleeve, the grounding pin is arranged on the second side of the European standard sleeve, the space occupied by the British standard plug on the shell is coincided with the space occupied by the European standard plug on the shell, the overall length of the shell is reduced, the overall volume of the product is reduced, and the development of product miniaturization is facilitated.

[0053] The above description is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field by using the content of the specification and drawings of the present application is also included in the patent protection range of the present application.
