Description
Technical field:
The utility model relates to position, a kind of hole encoding identification device.
Background technology:
At present in the present technique field, the identification of card code is had many implementations, common have card print conduction code identification circuit method, wireless IC inductive method, photoelectric reflection method of identification, a card punching method of identification etc.Wherein, card print conduction code identification circuit method production technology is too complicated, and need possess coating apparatus; Also there is complex process in the wireless IC inductive method, and card thickness is limited, simultaneously the too high limitation of cost; Higher, the complex structure of photoelectric reflection method of identification cost; Card punching method of identification has photoelectricity identification and electromechanics to discern two kinds, and the cost of photoelectricity identification is higher, and there is the relatively poor defective of reliability of contact in dynamo-electric identification.Dynamo-electric recognition structure of the prior art (with reference to figure 1) generally comprises a metal spring sheet and a pcb board (printed circuit board), metal spring sheet one end is fixedlyed connected with pcb board, the other end is formed with a contact with moving contact, pcb board is provided with corresponding contact, simultaneously, also be formed with the bending part that card is played position-limiting action on the metal spring sheet.Its principle of work is: after card inserts, if this unit card does not punch, then between the card moving contact that inserts the back contact and the stationary contact on the pcb board of below owing to the existence of paper card, make the two separation, not conducting of contact; If the punching of this unit card, then the hole passed on the card of the card moving contact that inserts the back contact still contacts the contact conducting with stationary contact on the pcb board of below.The disclosed a kind of short stroke, not to distinguish plug-in surface, antidestructive IC card holder of for example Chinese utility model patent 96109897.X, what it adopted is this class formation, the shortcoming of this structure is: because paper card is frequent and two face frictions of contact, damage the coating of contact surface of contact, reliability of contact is affected, correct recognition rata is low, and reduce serviceable life; Molecules such as the dust that paper card carries, paper scrap adhere to two surface of contact in contact easily, and the reliability of contact is reduced; The frequent insertion of paper card is taken out and is caused the distortion of position, contact, also can make poor contact of contacts.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and position, the hole encoding identification device of a kind of contact dependable performance is provided.
Position, a kind of hole encoding identification device that provides according to the utility model, constitute by a plurality of regularly arranged cellular constructions, each cellular construction comprises that a pcb board and is fixed on the metal spring sheet on this pcb board, be formed with a contact that extends on the described metal spring sheet downwards, has a moving contact on the described contact, has corresponding stationary contact on the described pcb board, described metal spring sheet has one from the described contact part that stretches out, described extension is formed with a sensing head that can probe into card punching, and its below is equipped with a mechanical position limitation plate.
Position, a kind of hole encoding identification device that provides according to the utility model has following advantage compared to existing technology: the utility model has increased by a sensing head that can probe into card punching on the metal spring sheet, overcome in the prior art, the shortcoming of the poor reliability that loose contacts such as the contact directly contacts with paper card and the contact of causing is stained, contact wear and contact distortion bring, by simple seal, can avoid the pollution of ambient impurities simultaneously to the contact to the contact.

The cellular construction synoptic diagram of position, a kind of hole encoding identification device that provides according to the utility model is provided Fig. 2;
Fig. 3 is the moving contact of contact among Fig. 2 and the enlarged diagram of the part of the stationary contact on the pcb board;
Fig. 4 is the vertical view of Fig. 3;
Fig. 5 also is the vertical view of Fig. 3, and wherein, the metal spring sheet is omitted;
Embodiment:
Referring to Fig. 1, as position, a kind of hole of the present utility model encoding identification device, constitute by a plurality of regularly arranged cellular constructions 1, each cellular construction comprises that a pcb board 11 and is fixed on the metal spring sheet 12 on this pcb board, be formed with a contact 121 that extends on the described metal spring sheet 12 downwards, has a moving contact 122 on the described contact 121, has corresponding stationary contact 111 on the described pcb board 11, described metal spring sheet 12 has one from described contact 121 part 123 that stretches out, described extension 123 is formed with a sensing head 124 that can probe into card punching, its below is equipped with a mechanical position limitation plate 13, the signal that pcb board 11 is used to finish the identification of this device connects with other circuit, metal spring sheet 12 has been born position, hole sensing and conduction, controls the break-make of sound contact simultaneously.
Referring to Fig. 1, described sensing head 124 is arc-shaped bend.
Referring to Fig. 1, described mechanical position limitation plate 13 comprises a flat board 131 and should upwards bend a limiting plate 132 that forms by flat board one end certainly that dull and stereotyped 131 are used for insertion, the removing direction of guide card, 132 insertion positions that are used to limit card of limiting plate.
Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described contact 121 is a V font, corresponding each described contact 121 is provided with an annular sealing strip 125 on the described pcb board 11, and annular sealing strip 125 can be avoided molecules such as dust, paper scrap to be attached to by other approach and cause loose contact on the contact.
The course of work of work of the present utility model is: after card inserts, if this unit card does not punch, then between the card sensing head 123 that inserts back metal spring sheet 12 and the lower floor's mechanical position limitation plate 13 owing to the existence of paper card, make the two separation, displacement upwards takes place in sensing head 123, and two surface of contact of contact separate and not conducting; If the punching of this unit card, then the card moving contact 122 that inserts back metal spring sheet 12 passes hole on the card and still contacts with stationary contact 111 on the below pcb board 11 and keep original state, contact conducting.
Above-mentioned several embodiment is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
