Abstract

This utility model discloses a spring probe-type contact module, including a contact pin fixing body and a spring type probe; a block on the fixing body is used to stop the forward road after the card enters; the spring type probe is installed on the fixing body, including a spring and a probe. This utility model can operate more reliably compared with prior spring-type contact structure, preventing rust and mould; the service life is extended and the probability of unable to read card is decreased.

Description

Spring probe contact module

Technical field

The utility model relates to a kind of spring probe contact module, especially relates to having spring probe contact module in a kind of card reader.

Background technology

Various card reader arrangement have appearred in development and development of technology along with society, and its use is very universal, is widely used in various occasions such as bank, gate inhibition, public transport, computer system, communication, safety, big convenience people's life.Card reader it is important and will carry out data read to the card that inserts, after data transfer has been examined various situations to computing machine, could finish other functions according to user's operation.

What but existing card reader generally adopted when Card Reader is the reed-type contact structure, has advantage of simple structure, but also has some shortcomings.Mildew as getting rusty easily under at wet environment; Wear and tear easily than long back service time and cause card reader minimizing in serviceable life, also bigger to the wearing and tearing of card; Because wearing and tearing and long-term the use are caused the reed distortion, thereby can not Card Reader.At above these defectives, though some improvement are also arranged, effect is all undesirable.

According to international standard, the contact should be 0.2-0.6N to the single-point pressure of card, (contact area is bigger and existing reed-type contact structure is for the reliability that guarantees to contact, in order to guarantee same pressure, will increase pressure), general pressure is about 1.5N, it is very difficult to meet international standards, and spring probe contact structure is easy to, and the consistance of pressure is fine.

Summary of the invention

The purpose of this utility model provides a kind of spring probe contact module, can work more reliably at existing reed-type contact structure, accomplish antirust mildew-resistant, the friction between minimizing and the card increases the service life, reduce can not Card Reader possibility, and meet international standard fully.

The purpose of this utility model is achieved in that a kind of spring probe contact module, comprise contact pilotage fixed body and spring probe, the spring probe comprises spring and probe, the contact pilotage that it is characterized in that the forward march after being used to block card enters fixedly washer is angle with described contact pilotage fixed body and fixedlys connected, described spring probe is installed on the described contact pilotage fixed body, directly wringing fit is pressed in the contact carrier, and is connected with the contact detection module by data line.

Contact pilotage described in the utility model fixedly washer promotes described contact carrier and makes described spring probe be subjected to spring pressure to contact chip and reading of data on the described card with after described card contacts.

Contact carrier described in the utility model and contact pilotage fixedly catch are connected with movable device, described contact is after fixedly catch blocks described card, thereby because of the stressed spacing motion that drives described contact carrier according to described movable device, so that described spring contact contacts described card.Described movable device is set to guide rail.

Contact carrier described in the utility model comprises the cylindrical hollow cavity, is used to hold described spring contact pilotage, and the spring contact pilotage is scalable, prevents and the card friction.The below of described contact carrier also is provided with a spacing point, is used for carrying out spacing to described contact pilotage fixed body.

Realize above-mentioned technical scheme, just can realize the purpose of this utility model.When IC-card is inserted the card reader of spring probe contact module, after IC-card pushes up the contact catch, this moment, contact frame and contact pilotage fixed body were owing to be subjected to the thrust of card, along with movable device moves downward, be contained in the spring probe contact on the contact carrier this moment because the pressure that is subjected between card and the contact carrier begins to shrink, IC contacts with card, arrives the spacing stop motion on the card reader support, transmit signal by the spring probe contact and give card reader, read the data on the IC-card.

Description of drawings

Fig. 1 is the card reader synoptic diagram of the utility model spring probe contact module;

Specific embodiment

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing,, can clearerly find out and understand advantage of the present utility model place by description to the utility model preferred embodiment.

As shown in Figure 1, when one driving force 1 is inserted card reader with IC-card 2, IC-card 2 pushes up the limited post on the contact carrier 3, contact carrier 3 is owing to be subjected to the thrust of card, along with the guide rail on the card reader slides forward and downward, be contained in the spring probe contact 4 on the contact carrier 3 this moment because the pressure that is subjected between card and the contact carrier 3 begins to shrink, IC2 contacts with card, arrive the spacing stop motion on the card reader, and clamp IC-card 2, spring probe contact 4 transmits signal through flexible FPC 5 and gives card reader, reads the data on the IC-card 2.

Spring probe contact 4 is points that probe contacts with IC-card 2, contact back probe reads IC-card 2 data and is transferred to the contact detection module, IC-card 2 enters the back near spring probe contact 4 from the bayonet socket that advances, the front end of IC-card 2 can touch the limited post on the contact carrier 3, thereby promote the contact catch, the contact catch transmits thrust again and gives contact carrier 3, reason owing to movable device, contact carrier 3 can move down, after spring probe contact 4 touches IC-card 2, produce certain pressure, can read the data of IC-card 2.

Spacing point can also be set, below contact carrier 3, be used for contact carrier 3 is carried out spacing, make it when stressed moving down, can not surpass certain limit, prevent that spring probe contact 4 from too contacting and damaging with IC-card 2.

Contact carrier 3 mainly is to be used to carry fixing spring formula probe contact 4, the bottom is provided with hollow cavity, internal diameter is tight with at the external diameter of spring probe, can be so that spring probe holds wherein, one end of spring is fastened on the inside of hollow cavity, one end connects spring probe contact 4, when spring probe contact 4 touches IC-card 2, because IC-card 2 constantly promotes catch, catch drives the stressed reason of contact carrier 3, the spring that will gradually reduce, thus guarantee to reduce the friction force that IC-card 2 impact spring formula probe contact 4 produce, reduce wearing and tearing, increase the service life; Simultaneously because the contractility of spring, thereby avoided the contact in long-term use, perhaps human factor makes the contact produce distortion, cause the contact can not contact card, so that card reader can not Card Reader.

Wherein, contact catch and contact carrier 4 in a certain angle fixedlying connected, preferably, the angle of the two is set to the right angle.

Movable device simply just can be set to rotating shaft, in contact catch and contact carrier 4 junctions; Also can be set to the curvilinear guide that circular arc or other are fit to, contact catch and both sides, contact carrier 4 junction are provided with two outstanding supports, are embedded in the guide rail, can slide in guide rail after stressed.

Here it is to be noted: those of ordinary skill in the art can make various suitable distortion or replacement on basis of the present utility model, but all these distortion or replacement all should belong to protection domain of the present utility model.
