Description

External adapter

Technical Field

The utility model relates to the technical field of connectors, in particular to an external adapter.

Background

A common apple data line generally includes an apple plug for plugging with an apple mobile phone, a USB plug for plugging with an adapter, and a cable main body connecting the apple plug and the USB plug.

The apple plug comprises a main board, an insulating base and a plug board, wherein the insulating base coats the main board, and one end of the plug board extends into the insulating base and is electrically connected with the main board. At present, one end of the cable main body connected with the apple plug also extends into the insulating base so as to be connected with the main board in a welding mode. Specifically, the production steps are as follows:

firstly, welding a plug board at one end of a main board, and then welding a core wire at one end of a cable main body at the other end of the main board to obtain a semi-finished product;

and secondly, placing the semi-finished product into a mold cavity for in-mold injection molding to form the insulating base for coating the main board.

Because the cable main part is wrapped in the insulating seat, consequently, the whole volume of apple plug is great, can't satisfy some extreme test scenes. Therefore, it is necessary to improve the conventional connection terminal such as an apple plug to solve the problem that the cable body is covered in the insulating base, which results in a large overall size.
