Although the function bases of various chargers are the same, for example, the output voltage of a mobile phone charger is basically 5V, the power plug standards and specification requirements of different countries on the charger are different, for example, a european standard plug is a two-pin plug, and a british standard plug is a three-pin plug. The difference in specifications causes people to have to carry two or more chargers with different plug standards when traveling or going on a business trip between different countries, thereby bringing inconvenience to people. Therefore, charger manufacturers design chargers capable of replacing plugs of different systems according to the use characteristics of different countries for power plugs; namely, the produced charger can be supplied only by replacing the standard plug of the corresponding country, or when a user uses the charger in different countries, the charger can be smoothly used for charging a mobile phone or a tablet by replacing the corresponding standard plug, thereby bringing great convenience to the production of enterprises and the use of the user. However, the problem of relatively large volume of the charger occurs, specifically, since the plug of the charger is replaceable, an electrical connection assembly needs to be disposed on the charger to form a movable connection (electrical connection) between the plug and the charger circuit, whereas in the prior art, in order to facilitate the assembly of the charger, the electrical connection assembly mainly uses two mounting seats to clamp the electrical connection terminal therebetween, and finally, the mounting seat is fixed in the charger housing; the volume of the mounting seat cannot be effectively reduced, so that the volume of the charger is increased.
