Description
Technical field
The utility model belongs to protection jack technology field more particularly to a kind of power-off protection socket.
Background technique
Present non-standard automatic equipment Industry, largely measures the place of detection data and action control using PC
Reason wants pass hull closure when equipment is out of service, and normal process is first to close PC host, then cut off main power source, in practical behaviour
In work, operator will appear maloperation phenomenon, that is, be initially switched off main power source, so that PC host be caused to power off disorderly closedown, hold
Mainboard easy to damage and program data is caused to be lost, so needing a kind of power-off protection socket, avoids PC host disorderly closedown
The appearance of phenomenon.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of power-off protection socket, when operator misses
When operation, avoids damaging PC host, prevent mainboard to be damaged and program data is avoided to lose.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of power-off protection socket, including by front end
The shell and be located at the intracorporal pcb board of the shell that shell and rear end housing form, are provided with jack on the front-end case, described
PCB substrate is provided on end housing afterwards, the pcb board is connect by spacer column with the PCB substrate, and the pcb board is close to institute
It states and is provided with power supply terminal, relay and mistake flow fuse on the face of front-end case.
In one preferred embodiment of the utility model, the jack is bipod jack or three foot jacks.
In one preferred embodiment of the utility model, the power supply terminal quantity is consistent with the jack quantity.
In one preferred embodiment of the utility model, the shell both ends are provided with control interface.
In one preferred embodiment of the utility model, the control interface include be located at the intracorporal public connector of the shell with
And the female connectors outside the shell, the public connector are connected with the female connectors.
In one preferred embodiment of the utility model, described shell one end is provided with external interface and electrically connects with external structure
It connects.
In one preferred embodiment of the utility model, indicator light is provided in the shell.
The utility model solves defect present in background technique, the utility model have it is following the utility model has the advantages that
The utility model can realize the protection to PC host, work as operation in the case where operator's abnormal operation
When personnel are initially switched off main power source, PC host is not in disorderly closedown phenomenon, mainboard and internal processes number to PC host
According to protection is provided, mainboard is avoided to be damaged, it is therefore prevented that program data is lost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples；
Fig. 1 is the overall structure diagram of the preferred embodiment in the utility model；
Fig. 2 is the schematic diagram of internal structure of the preferred embodiment in the utility model；
Fig. 3 is the working circuit diagram of the preferred embodiment in the utility model；
In figure: 1, shell；11, front-end case；12, rear end housing；2, pcb board；3, PCB substrate；4, power supply terminal；5, after
Electric appliance；6, flow fuse is crossed；7, control interface；8, external interface；9, indicator light.
Specific embodiment
The utility model is described in further detail presently in connection with drawings and examples, these attached drawings are simplified
Schematic diagram only illustrates the basic structure of the utility model in a schematic way, therefore it only shows structure related with the utility model
At.
As shown in Figures 1 and 3, a kind of power-off protection socket, including the shell being made of front-end case 11 and rear end housing 12
Body 1 and the pcb board 2 in the shell 1, are provided with jack on the front-end case 11, are arranged on end housing 12 after described
There is PCB substrate 3, the pcb board 2 is connect by spacer column with the PCB substrate 3, and the pcb board 2 is close to the front-end case
It is provided with power supply terminal 4, relay 5 on 11 face and crosses flow fuse 6.
Specifically, the jack is bipod jack or three foot jacks.
Further, 4 quantity of power supply terminal is consistent with the jack quantity.
Specifically, 1 both ends of shell are provided with control interface 7.
Further, the control interface 7 includes the public connector in the shell 1 and is located at the shell 1
Outer female connectors, the public connector are connected with the female connectors.
Specifically, described 1 one end of shell is provided with external interface 8 and external structure is electrically connected.
Further, indicator light 9 is provided in the shell 1.
Utility model works principle: as shown in figure 3, when enabling signal generates, main circuit is powered on and self-locking.Starting letter
Before number not disappearing, all power-off signals do not judge, after enabling signal disappears, theres are two kinds of monitoring in circuit: (1) supervising outside
Control disconnects main circuit after 3s after external power supply is disconnected from external interface 8；(2) internal control, when electric current is in main circuit
When zero lasting 10s, main circuit is disconnected.
To sum up, the utility model can realize the guarantor to PC host in the case where operator's abnormal operation
Shield, when operator is initially switched off main power source, PC host is not in disorderly closedown phenomenon, mainboard to PC host and interior
Portion's program data provides protection, and mainboard is avoided to be damaged, it is therefore prevented that program data is lost.
It is above enlightenment according to the desirable embodiment of the utility model, through the above description, related personnel is complete
Various changes and amendments can be carried out in the range of without departing from this item utility model technical idea.This item utility model
Technical scope be not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
