Abstract
The invention provides a magnetic absorption type contact-closed power supply device comprising a safety plug and a safety socket, wherein the safety socket is provided with movable conductive spring plates; the safety plug and the safety socket are respectively provided with two permanent magnets playing the roles of absorption and location; meanwhile, the conductive spring plates arranged on the safety socket are also controlled to be closed or opened by the permanent magnets; and when the safety plug and the safety socket are closed, the permanent magnets absorb the conductive spring plates of the safety socket to connect a power supply circuit, when the safety plug is separated from the safety socket, the power supply circuit is disconnected under the gravity actions of the spring plates and the permanent magnets on the spring plates, at this moment, a contact of the safety socket has no electricity, and thus, the function of safety protection is achieved. The magnetic absorption type contact-closed power supply device has the advantages of reasonable design, artful conception, simple member, strong practicability, high technical integration degree, simplicity and easiness in installation and maintenance, convenience and easiness in operation, flexibility in use, capability of providing safe and reliable protection for users and huge market prospect.
Description
Technical field
The invention belongs to the dc low-voltage electric supply installation, be specifically related to the following direct current safe power supply of a kind of 36V device.
Background technology
At present, for equipment such as display, notebook computer, part desktop computers, all adopt low-voltage DC supply, way is through directly being connected directly to dc power source adapter to the 220V alternating current, supplying power to power consumption equipment through after the transformation usually.It is complicated that this supply power mode exists wiring, and in use, the user will be directly near 220V supply line, exists very big potential safety hazard.For the big low-voltage DC supply system of this type of concentrated usage quantity of school's audio-visual education room, the defective of existence particularly highlights, and safeguards and overhaul a big problem especially.
Summary of the invention
For overcoming the deficiency of prior art, the present invention proposes a kind of modern design, specific aim is stronger, installs and uses simply, and magnetic-type the touching of safe and reliable low pressure closed electric supply installation.
For achieving the above object; The present invention is achieved through following technical scheme: a magnetic-type touching closed electric supply installation; Be made up of safety socket and safety plug, two blocks of magnet and two contacts are housed in the safety plug, two contacts, a slice are housed in the safety socket can movable electroconductive elastic sheet and two blocks of magnet; And wherein a magnet is fixed on the electroconductive elastic sheet, and electroconductive elastic sheet is installed on the safety socket.
When safety plug and safety socket closed, safety plug internal magnet absorption safety socket internal magnet played the effect of location simultaneously and plays electroconductive elastic sheet in the adhesive safety socket, makes it the switch closure effect that reliably contacts with the contact; When safety plug separates with safety socket, because the gravity acting in conjunction of interior electroconductive elastic sheet of safety socket and permanent magnet breaks away from electroconductive elastic sheet and contact; Play the effect that switch turn-offs, thereby play the safeguard protection effect, at this moment; The safety socket upper contact is not charged; No matter moist, misoperation, even short circuit can be not accidents caused.
Compared with prior art, the present invention has following technical advantage:
1: reasonable in design, simple in structure, safe and reliable, easy to use, as the regular tap socket panel, do not need the extra professional training of carrying out when installing and using, can be high with existing promotional value;
2: this device is skillfully constructed, and is safe, also realizes operability flexibly easily simultaneously, expands its use value and scope greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a safety socket structure sketch map of the present invention.
Among the figure: 1,2 is the contact, and 3,4 is permanent magnet, and 5 is the shell fragment holder, and 6 is electroconductive elastic sheet, and 7 is socket, and 8 are DC power supply input positive source, and 9 are DC power supply input negative pole;
Fig. 2 is a safety plug structural representation of the present invention.
Among the figure, 10 is the DC power supply output cathode, and 11 is the DC power supply output negative pole, and 12,13 is the contact, and 14,15 is permanent magnet, and 16 is terminal screw, and 17 is plug body.
Embodiment
The N utmost point of permanent magnet 3 up in the safety socket; The S utmost point of the permanent magnet 15 of corresponding safety plug; Play adhesive electroconductive elastic sheet 6, the effect of control mains switch, the S utmost point of permanent magnet 4 is up in the safety socket; The N utmost point of the permanent magnet 14 of corresponding safety plug, the positioning action of safety socket and safety plug is played in permanent magnet 4 and permanent magnet 12 and permanent magnet 3 and permanent magnet 15 actings in conjunction.
Direct current supply line negative pole 9 direct connecting terminals 1, anodal 8 are connected to electroconductive elastic sheet 6,, safety socket power supply output line road negative pole 11 connecting terminals 12, anodal 10 connecting terminals 13.
When safety plug B and safety socket A close; The contact 1 of the contact 12 touch-safe sockets of safety plug, 2 contact contacts 15, contact, permanent magnet 4 and permanent magnet 14 are because magneticaction absorption simultaneously; Permanent magnet 15 and permanent magnet 3 are because magneticaction absorption; Play the role of positioning, permanent magnet 15 absorption permanent magnets 3 also make electroconductive elastic sheet 6 engage energising with contact 2, thereby accomplish the circuit supply action.
When safety plug separates with safety socket, owing under the acting in conjunction of permanent magnet 3 weight and the weight of shell fragment own, electroconductive elastic sheet 6 is separated with contact 2, thereby reach the outage effect.
According to technique scheme; Those skilled in the art according to actual needs; Also can design magnetic-type the touching of low pressure of more different structure forms and close electric supply installation, but the foregoing description is merely explanation the present invention and enumerating, and is not to be used to limit the present invention; The structure of any effects equivalent based on the conversion of present technique scheme institute all belongs to protection scope of the present invention.
Claims (4)
1. magnetic-type the touching of a low pressure closed electric supply installation; Form by safety socket and safety plug; It is characterized in that: safety socket and safety plug have permanent magnet, and safety socket and safety plug wherein have one group of permanent magnet also to be responsible for the electroconductive elastic sheet of adhesive activity through the mutual adhesive of permanent magnet location; Make switch closure, connect circuit; When safety socket separated with safety plug, the safety socket contact was not charged.
