Description

Technical Field

[0001] The utility model relates to the technical field of adapter socket manufacturing, in particular to a counterweight type adapter socket structure. Background Art

[0002] Common household power sources include 110V or 220V AC power, but most portable electronic devices such as smart watches, mobile phones, tablets, laptops and handheld game consoles are equipped with rechargeable batteries and are no longer restricted to being connected to an AC wall plug when in use. Such portable electronic devices often use a charger connected to a wall plug when charging. The charger converts the AC voltage supplied by the wall plug into a DC voltage, and then the DC output port of the charger, such as a Type A USB port or a Type C USB port, outputs the DC voltage for use by the portable electronic device.

[0003] Conversion sockets generally refer to converting different power plugs of different countries or power plugs of a certain country into power plugs of another country or multiple countries, so that power plugs of multiple countries or a certain country can be plugged into sockets of another country. This allows plugs of different countries to be interoperable in different countries around the world, solving the problem that electrical appliances from different countries around the world can be used in other countries. There are two types of conversion sockets: one is a simple socket type conversion, and the other is a conversion socket that can adapt to stable voltage (fixed voltage regulation). For most of the existing electrical appliances in China, they are adapted to voltages between 180-250V, so for general requirements, you can use them normally!

[0004] However, the existing technology has the following problems:

[0005] 1. When the existing adapter socket is in use, the power input interface and the power output interface are located on opposite sides, and the power input interface is plugged into the wall plug through a pin. When the external plug is connected to the power output interface, the weight of the plug and the wire connected to the plug will generate a torque on the power input interface, causing the extension cord or adapter socket of the above-mentioned case to deflect downward relative to the wall plug. After long-term use, the pin clip of the wall plug will loosen;

[0006] 2. When the pin clip of the current adapter socket is loose, the clamping force of the pin clip on the pin is insufficient, so the contact point is too small, and the contact point overheats, causing the above-mentioned case to be damaged. Utility Model Content
