Abstract

The utility model discloses a power socket having a USB (Universal Serial Bus). It is characterized in that the power socket having the USB also includes a step-down circuit, a swing arm shaft and a swing arm. The swing arm is fixed in a USB base installation groove in a rear cover through the swing arm shaft. The step-down circuit is provided with a contact piece. A spring contact is installed in a position corresponding to the contact piece. The contact piece connects with one end of the connection wire electrically. The other end of the connection wire connects with a power source master piece module electrically. One end of the swing arm is corresponding to the spring contact while the other end of the swing arm works as a jack of a USB base and exposes on a face plate. When a USB plug is inserted into the USB jack, the other end of the swing arm presses the spring contact to make the spring contact connect with the contact piece on the step-down circuit electrically. And the contact piece on the step-down circuit connects with the connection wire electrically to conduct an AC into a charging circuit. When the USB plug is unplugged, the swing arm returns under an elastic force of the spring contact. Thus, a 5V low voltage power source can be used once the plug is inserted. And the power supply can be cut if no need. A switching between the 5V low voltage charging and the 220V normal voltage power utilization can be realized freely, thereby facilitating cell phone charging and other usages of normal voltage power utilization.

Description

Have the supply socket of USB

Technical field

The utility model belongs to technical field of hardware electric appliances, relates to the supply socket of a kind of USB of having, relates in particular to a kind of supply socket that has USB of the 5V of having DC power supply output, is specially adapted to cell-phone charging.

Background technology

Traditional supply socket (insert row) is made up of jack assemblies, does not have reduction voltage circuit, can only provide 220V to be electrically connected function singleness; During the low-voltage electrical apparatus charging, need charger to insert traditional supply socket power transformation; Carry low-voltage electrical apparatuses such as mobile phone, all must carry charger, use inconvenience.

Summary of the invention

The utility model discloses the supply socket of a kind of USB of having, and traditional supply socket (insert row) does not have reduction voltage circuit in the prior art to solve, and can only provide 220V to be electrically connected problems such as function singleness.

The utility model comprises supply socket, and supply socket comprises power supply master slice assembly, ground connection master slice assembly, panel, bonnet, connecting line; Panel is fixedly connected with bonnet; It is characterized in that also comprising reduction voltage circuit; Reduction voltage circuit is installed in the bonnet; Has the wide USB seat mounting groove of power supply master slice assembly mounting groove, ground connection master slice assembly mounting groove and USB seat on the bonnet; Power supply master slice assembly, ground connection master slice assembly are inserted in the corresponding groove of bonnet; When the panel bonnet closed, power supply master slice assembly and ground connection master slice assembly were fixing naturally in the corresponding groove of bonnet; The USB seat connects reduction voltage circuit and is installed in the USB seat mounting groove of the USB seat equal-width groove on the bonnet, and the jack of USB seat is exposed on the panel; Reduction voltage circuit and USB seat have a pair of normally opened contact; USB plug inserts USB seat jack, and the normally opened contact between reduction voltage circuit and the USB seat is closed, and power supply is communicated with the access reduction voltage circuit; Realize the 5V low-tension supply with inserting with usefulness, the time spent does not cut off the electricity supply automatically, and the charging of 5V low pressure is changed with the electricity consumption of 220V normal pressure freely, makes things convenient for other purposes of cell-phone charging and normal pressure electricity consumption to use.

The utility model is characterized in that also comprising arm shaft, swing arm; Contact chip is arranged on the reduction voltage circuit, and corresponding contact chip position is equipped with spring contact; Contact chip is electrically connected with connecting line one end, and the connecting line other end is connected with power supply master slice electrical component; Swing arm is fixed in the bonnet USB seat mounting groove by arm shaft, and an end of swing arm is corresponding with spring contact, and the other end of swing arm is exposed on the panel as the jack of USB seat; When USB plug inserted USB seat jack, the other end of swing arm pressed spring contact, made that contact chip is electrically connected on spring contact and the reduction voltage circuit, and contact chip is electrically connected with connecting line again on the reduction voltage circuit, and civil power is imported charging circuit; When pulling out USB plug, swing arm receives the elastic force return of spring contact, thereby the socket of USB seat is covered.

The utility model reduction voltage circuit electricity output 5V.

The utility model good effect is: charger and supply socket isolated combination, saved charger case and attaching plug, and dual-use, easy to use, save raw material.Adopt the insertion of USB plug and extract access and disconnection, can do the USB port lid again and open and close, make charger time spent civil power insert not time spent civil power automatic disconnection power saving through swing arm control charger power supply.

Description of drawings

Fig. 1 is the utility model master TV structure sketch map;

Fig. 2 is the utility model plan structure sketch map;

Among the figure: 1 panel, 2 jacks, 3 ground connection master slice assemblies, 4 bonnets, 5 contact chips, 6 power supply master slice assemblies, 7 circuit boards, 8 connecting lines, 9 spring contacts, 10 USB seats, 11 electronic original parts, 12 arm shafts, 13 swing arms.

Embodiment

An embodiment of accompanying drawings the utility model.

Like Fig. 1, shown in Figure 2: present embodiment comprises panel 1, jack 2, ground connection master slice assembly 3, bonnet 4, contact chip 5, power supply master slice assembly 6, reduction voltage circuit circuit board 7, connecting line 8, spring contact 9, USB seat 10, electronic original part 11, arm shaft 12, swing arm 13;

Circuit board 7 is inserted in the groove of bonnet 4; Be printed with contact chip on the reduction voltage circuit circuit board 7, corresponding printed contact position is equipped with spring contact 9; Swing arm 13 is fixed on the bonnet 4 by arm shaft 12, an end of swing arm 13 and spring contact 9 corresponding contacts, and the other end of swing arm 13 is as the USB Socket cover; Printed contact 5 is electrically connected with connecting line 8 one ends, and connecting line 8 other ends are electrically connected with power supply master slice assembly 6; Power supply master slice assembly 6 is inserted in the bonnet 4 corresponding grooves with ground connection master slice assembly 3; When panel 1 bonnet 4 closed, power supply master slice assembly 6 was fixing naturally in bonnet 4 corresponding grooves with ground connection master slice assembly 3; By four screws panel 1 is fixedly connected with bonnet 4;

When USB plug is stirred Socket cover to the right when inserting in the USB hole, the other end of swing arm 13 pressing spring contact 9 left makes that printed contact is electrically connected on spring contact 9 and the circuit board, and printed contact is electrically connected with connecting line 8 again, and civil power is imported charging circuit.
