Background

Common household power supplies include 110V or 220V ac, but most portable electronic devices such as smartwatches, mobile phones, tablet computers, notebook computers, palm game machines and the like are configured with rechargeable batteries, which are not limited by wall plugs to which ac power is required to be connected during use, and such portable electronic devices are often connected to the wall plugs by a charger during charging, the charger converts ac voltage supplied by the wall plugs into dc voltage, and then the dc voltage is output by a dc output port of the charger, such as a USB port of TypeA or a USB port of TypeC, for use by the portable electronic devices.

In order to enable the adaptor socket to simultaneously provide direct current voltage and alternating current voltage, a direct current output port and an alternating current output port are simultaneously arranged on the adaptor socket, for example, a ' power relay socket with direct current charging and alternating current socket function ' of the patent publication number CN206962155U of the people's republic of China comprises at least one socket body, wherein the socket body is of a hexahedral structure, two opposite side surfaces in the length direction of the socket body are provided with a power input interface and a power output interface which are electrically connected with each other, and at least one side surface of four surfaces surrounding the length direction of the socket body is provided with an output slot which is electrically connected with the power input interface; an alternating current-direct current conversion unit is arranged in the socket body.

However, when the adaptor socket of the above-mentioned prior art is used, because the power input interface and the power output interface are located at opposite sides, the power input interface is plugged into the wall plug through the pins, when the external plug is connected to the power output interface, the weight of the plug and the wires connected with the plug will generate moment to the power input interface, so that the extension line or the adaptor socket of the above-mentioned prior art will deflect downwards relative to the wall plug, and under long-term use, the pin clamping piece of the wall plug will be released, so that the pin clamping piece of the wall plug cannot maintain the clamping force in accordance with the specification, if the adaptor socket is not placed or is used continuously, there is a high possibility that the contact point is too small due to insufficient clamping force of the pin clamping piece clamped on the pin when the extension line or the adaptor socket of the above-mentioned prior art is used, and the situation that the contact point is damaged due to overheating occurs.

The multifunctional socket with the patent publication number of CN201466427U comprises a base body, wherein an alternating current socket and a USB socket are arranged on the base body.

The utility model provides a "socket with illumination and USB interface" of chinese people's republic of China patent publication No. CN201541034U comprises lamp shade and the box body that casing reciprocal swing joint constitutes, be equipped with mounting panel and a plurality of LED lamp in the lamp shade, the lamp shade is equipped with the switch that links to each other with the LED lamp electrode outward be provided with a plurality of sockets and USB interface of arranging in order on the panel, with the parallel a plurality of switches of arranging in order of this socket and interface, a switch control is a socket and interface parallel with this switch break-make, the bottom plate on be fixed with a plug be equipped with AC/DC conversion circuit in the cavity, its input is connected with alternating current power supply, the output is connected with more than one USB interface.

The utility model provides a "multi-functional socket of switching type" of people's republic of China patent publication No. CN213936807U which includes: the movable plug is characterized in that an inserting notch is formed in the back of the front end of the fixed socket, three contact terminals are arranged on the back side of the inserting notch, a high-voltage alternating current seat is arranged at the front end inside the fixed socket, socket terminals are arranged in the high-voltage alternating current seat and are correspondingly electrically connected with the contact terminals, socket through holes are correspondingly formed in the fixed socket, a conversion circuit board is arranged at the back end inside the fixed socket and is correspondingly electrically connected with the contact terminals, a USB socket is arranged on the conversion circuit board, a USB socket through hole is correspondingly formed in the fixed socket, the movable plug is embedded into the inserting notch of the fixed socket, an electric connection plug piece is arranged on the back of the movable plug, an embedded notch is formed in the front lower end of the movable plug, and a terminal clamping piece is arranged in the notch.

However, the pins of the above-mentioned prior art are all disposed close to one side of the adaptor, the dc socket area or/and the ac socket area are disposed far from the pins and are disposed at the other side of the adaptor, and under the condition that the dc socket area is configured, an electronic component for converting high voltage into low voltage and outputting dc is required to be disposed in the adaptor; generally, electronic components have a weight, and as the wattage provided increases, the weight of the electronic components increases. There is also an imbalance in the weight of the adapter socket, which can lead to the problem of loosening the wall plug pin clips over extended use.

In order to more clearly illustrate the problem of unbalanced weight caused by the prior art socket, please refer to fig. 11, 12 and 13, under the above configuration, the center of gravity is biased to the position of the electronic component, i.e. the position of the ac socket area B or the dc socket area C, when the socket a is used, the pin A1 of the socket a is inserted into the wall plug D, and the socket a is biased due to its center of gravity, and a moment is generated at the connection position of the pin A1 inserted into the wall plug D. Under long-time use, the pin A1 can expand the clamping gap of the pin clamping piece in the wall plug D, so that the pin clamping piece in the wall plug D can not provide clamping force meeting the specification.

Besides, when the socket a is connected with a plurality of plugs of electrical appliances, the plugs are far away from the pins A1 of the socket a, and the weight of the plugs and the wires will generate moment on the connection portion of the pins A1 inserted into the wall plug D, so that the deflection of the socket a is more serious.
