Description

Technical Field

[0001] The utility model relates to the field of European standard plugs, in particular to a combined plug. Background Art

[0002] The European plug standard specifies plug shape. The universally used two-pronged round plug in European countries ensures proper insertion and prevents safety hazards caused by poor contact or accidental contact. Furthermore, the European plug standard specifies the size and shape of the plug to ensure proper insertion and prevent poor contact or short circuits caused by mismatched dimensions.

[0003] The existing European standard plug has a limited shape. Therefore, in actual production, in order to realize the combination of the charging structure and the plug, the design structure is relatively complex, including assembly and positioning.

[0004] Of course, there are also structures in which the charging shell and the plug shell are set to be of equal diameter, such as Chinese patent CN202323141496.8. Correspondingly, their volume is larger, and the process is more complicated during actual use and assembly. At the same time, in mold production, the production cost of the bottom shell and the plug socket is relatively high. In actual production, the larger the volume and the greater the height, the higher the mold cost. Utility Model Content

[0005] The main purpose of the utility model is to provide a combined plug, which aims to realize charging and European standard plug integration through a combined structural design, while being simple to assemble and having low production cost.

[0006] To achieve the above-mentioned purpose, the present invention provides a combined plug, comprising:

[0008] The second opening is provided with a back cover, the back cover is provided with a through hole, the through hole is provided with a connector, and the connector is fixedly installed on the first PCB board;

[0009] The socket shell is flat, and the two ends of the socket shell extend out of the two sides of the main shell. The socket shell is provided with a second inner cavity, and the second inner cavity is provided with a secondary PCB board. The secondary PCB board is electrically connected to the first PCB board or the second PCB board. A front cover extends from the rear of the socket shell, and the front cover is adapted to the shape of the first opening and is installed therein.

[0010] The front end of the second inner cavity is provided with a third opening;

[0011] The plug post seat is similar in shape to the third opening and partially extends into the second inner cavity, and the plug seat is provided with a positive pole and a negative pole arranged at intervals,

[0012] The auxiliary PCB is provided with a positive pole clamp and a negative pole clamp, and the positive pole and the negative pole respectively extend into the positive pole clamp and the negative pole clamp and are electrically connected.

[0013] By setting the structure of the plug as the main shell, the rear cover, the socket shell and the plug post seat, in actual installation, the size of each part is small, so that the mold processing is easier, at the same time, in actual assembly, the first PCB and the second PCB are installed in the first cavity, the positive pole and the negative pole are integrally injection molded with the plug post seat, and when the plug post seat and the socket shell are installed first, they can be directly clamped in the positive pole clamp and the negative pole clamp, thereby reducing the welding process, effectively improving the installation efficiency, and the stability is good.
