Abstract
The utility model discloses a direct current socket for a wall. The direct current socket comprises a PCB (Printed Circuit Board) and a power supply plug bush arranged on the PCB, wherein a microswitch for controlling the power supply plug bush to be powered on or off is also arranged on the PCB, and the moving contact of the microswitch is arranged at the bottom end of the power supply plug bush. A singlechip and an MOS (Metal Oxide Semiconductor) transistor are arranged on the PCB, the microswitch is connected with the singlechip, the singlechip is connected with the MOS transistor, and the MOS transistor is connected with the power supply plug bush. The singlechip and the MOS transistor are arranged on the back surface of the PCB, and the microswitch and the power supply plug bush are arranged on the frontage of the PCB. The direct current socket is safer and more reliable in use, and can be used for avoiding the problem that the force performance and electrical performance of the plug bush are reduced due to electric arc which is produced by displacement and friction between the socket and a plug; and the socket and the plug are powered on in the state of no mutual displacement, the usage effect and the service life of the socket and the plug are better, and the plug is inserted or extracted more smoothly.
Description
Technical field
The utility model relates to a kind of socket, particularly relates to a kind of wall direct current jack.
Background technology
Traditional wall direct current jack is not controlled power supply sleeve energising on pcb board or the device of outage, and when plug directly inserted socket, bringing onto load was connected galvanic moment and can be produced spark, and the galvanic characteristic such as flashing can cause electricity consumption dangerous.
The utility model content
Based on this, for the problems referred to above, the utility model proposes the more safe and reliable wall direct current jack of a kind of use.
The technical solution of the utility model is: a kind of wall direct current jack, comprise pcb board and the power supply sleeve of being located on pcb board, also be provided with the sensitive switch of controlling the energising of power supply sleeve or outage on described pcb board, the moving contact of this sensitive switch is located at the bottom of described power supply sleeve.
Before plug inserted the wall direct current jack, the power supply sleeve on pcb board was in the state of outage; When plug inserts the wall direct current jack, at first the latch of plug inserts in the power supply sleeve, when the latch of plug thoroughly inserts power supply sleeve bottom, the latch end of plug touches the moving contact of sensitive switch, impel the moving contact action, make the sensitive switch conducting, thereby make the energising of power supply sleeve, and then the safety that guarantees to use is with reliable.
In a preferred embodiment, also be provided with single-chip microcomputer and metal-oxide-semiconductor on described pcb board, described sensitive switch connects single-chip microcomputer, and single-chip microcomputer connects metal-oxide-semiconductor, and metal-oxide-semiconductor connects described power supply sleeve.The purpose that arranges like this is, the latch end of plug touches the moving contact of sensitive switch, impel the moving contact action, after the sensitive switch conducting, Continuity signal is transferred to single-chip microcomputer, single-chip microcomputer is transferred to metal-oxide-semiconductor after signal is processed, and the switch of metal-oxide-semiconductor is controlled the energising of power supply sleeve, and this kind mode can make whole wall direct current jack operation more stable.
In a preferred embodiment, described single-chip microcomputer and metal-oxide-semiconductor are located at the back side of described pcb board, and described sensitive switch and power supply sleeve are located at the front of described pcb board.Purpose is the space of using better on pcb board, also can make design more attractive in appearance, practical.
The beneficial effects of the utility model are:
(1) use safety and reliable more, the problem that the electric arc of having avoided being subjected to displacement, rubbing and produce between socket and plug causes sleeve power performance, electrical property to descend;
(2) plug and socket are switched under the state that mutually is not subjected to displacement, and make the result of use of socket and plug and life-span better, plug more smooth and easy.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Embodiment:
To shown in Figure 3, a kind of wall direct current jack comprises pcb board 10, is located at power supply sleeve 20, fixed mount 40, panel 50, shutter 60, cover 70 and back seat 91 on pcb board 10 as Fig. 1.Also be provided with the sensitive switch 30 of controlling 20 energisings of power supply sleeve or outage on described pcb board 10, the moving contact 30a of this sensitive switch 30 is located at the bottom of described power supply sleeve 20.
In the present embodiment, also be provided with single-chip microcomputer and metal-oxide-semiconductor on described pcb board 10, described sensitive switch 30 connects single-chip microcomputer, and single-chip microcomputer connects metal-oxide-semiconductor, and metal-oxide-semiconductor connects described power supply sleeve 20.The purpose that arranges like this is, latch 90 ends of plug 80 touch the moving contact 30a of sensitive switch 30, impel moving contact 30a action, after sensitive switch 30 conductings, Continuity signal is transferred to single-chip microcomputer, single-chip microcomputer is transferred to metal-oxide-semiconductor after signal is processed, and the switch of metal-oxide-semiconductor is controlled 20 energisings of power supply sleeve, and this kind mode can make whole wall direct current jack operation more stable.
In the present embodiment, described single-chip microcomputer and metal-oxide-semiconductor are located at the back side of described pcb board 10, and described sensitive switch 30 and power supply sleeve 20 are located at the front of described pcb board 10.Purpose is the space of using better on pcb board 10, also can make design more attractive in appearance, practical.
