Abstract
The utility model discloses a non contact card approaching detecting magnetic switch, which comprises a dynamic contact piece and a static contact piece, wherein the dynamic contact piece is provided with a permanent magnetic steel; the outer sides of the dynamic contact piece, the static contact piece and the permanent magnetic steel are provided with casings made of non-conducting magnetic materials; the dynamic contact piece and the static contact piece made of conducting materials can be designed into normally open structures, normally closed structures and two static contact pieces made of the conducting materials and one dynamic contact piece made of the conducting materials to constitute normally open and normally closed structures. The utility model has the advantages of simple structure low cost, easy installation, flexible interface with a circuit and convenient use. Particularly the output contact point of the utility model can be designed into the normally open structures, or the normally closed structures, or the normally open and normally closed structures. The utility model can be suitable for the needs of various card reading devices.
Description
Technical field
The utility model relates to a kind of non-contact card near sense switch, and particularly a kind of non-contact card is near detecting magnetic switch.
Background technology
Non-contact IC card is the information exchange of finishing IC-card and reader device by the mode that the antenna in the reader device constantly transmits and receives radio wave, because circuit long-term work power consumption is very big, and battery-powered reader device can't support that circuit works long hours.For reducing power consumption, prolong the useful life of battery, must take circuit dormancy at ordinary times, again circuit is waken up during Card Reader, circuit continued the working method of dormancy again after Card Reader was finished.Present non-contact IC card and reader device generally adopt the wake-up of button mode, promptly must click start button earlier before swiping the card, and have caused inconvenience for user's use.
Summary of the invention
Whether the purpose of this utility model is to provide a kind of can the detection to have clamping near for the deficiency that solves above-mentioned technology, automatically produce triggering signal when having clamping near, wake reader device up to sticking into capable information operating, when not having card, do not produce triggering signal, make reader device keep little power consumption non-contact card of resting state near detecting magnetic switch.
In order to achieve the above object, the approaching magnetic switch that detects of a kind of non-contact card that the utility model is designed, it comprises movable contact spring and static contact, and movable contact spring is provided with permanent-magnet steel, is provided with the shell that non-magnetic conductive material is made outside movable contact spring, static contact and permanent-magnet steel.In the specific implementation, the movable contact spring of conductive material and static contact can be arranged to normal opening structure, also can be arranged to normally closed structure, can also be arranged to have two of the static contacts of conductive material and movable contact spring a slice of conductive material, and formation is often opened, normally closed structure.This magnetic switch is contained in the district that swipes the card of reader device, and the supporting use of non-contact IC card of magnetic conductive metal piece or permanent magnetic sheet just can be arranged with the inside envelope.
The non-contact card that the utility model obtains is simple in structure near detecting magnetic switch, and cost is low, is easy to install, flexible with circuit interface, easy to use, output contact particularly of the present utility model can often be made as to be opened, normally closed or open and close the structure have concurrently, can adapt to the needs of various reader devices.

Among the figure 1, static contact; 2, movable contact spring; 3, permanent-magnet steel; 4, shell; 5, IC-card; 6, permanent magnetic sheet.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1 and Figure 2, the non-contact card that present embodiment is described is near detecting magnetic switch, it comprises movable contact spring 2 and static contact 1, and movable contact spring 2 is provided with permanent-magnet steel 3, is provided with the shell 4 that non-magnetic conductive material is made outside movable contact spring 2, static contact 1 and permanent-magnet steel 3.
This non-contact card near detect magnetic switch no supporting non-contact IC card 5 near the time be in open state, when supporting non-contact IC card 5 near the time, envelope has magnetic conductive metal piece or permanent 6 pairs of non-contact cards of magnetic sheet near the permanent-magnet steel 3 generation effects that detect in the magnetic switch in the non-contact IC card 5, make movable contact spring 2 and static contact 1 closure, thereby excite reader device.After non-contact IC card 5 left, movable contact spring 5 was reduced to open state.
Embodiment 2:
As shown in Figure 3, Figure 4, the non-contact card described of present embodiment near detect magnetic switch no supporting non-contact IC card 5 near the time be in closure state.Supporting non-contact IC card 5 near after then become open state.
Embodiment 3:
As Fig. 5, shown in Figure 6, the non-contact card that present embodiment is described has two static contacts 1 near detecting magnetic switch.No supporting non-contact IC card 5 near the time be in a kind of closure state, supporting non-contact IC card 5 near after then become another kind of closure state.
Claims (4)
