TECHNICAL FIELD

[0001] The present application relates to the technical field of IC card reading device, and particularly relates to an IC card connector. BACKGROUND

[0002] The IC card connector is an important electronic device interface, which allows the electronic device to interact with the IC card, realizes the functions of data reading and writing, verification and the like. Due to the high-speed card reading capability and the cheap and good characteristics, the IC card connector is widely applied to many scenes such as smart meter, set-top box, SIM / UIM remote card supplementing, card writing, tax control card reading, bank chip card reading and writing and the like.

[0003] Generally, the IC card connector adopts the contact clamping mode with a small spacing less than the thickness of the IC, so that the contact abuts against the IC card. When reading and writing the IC card, the chip end of the IC card is generally inserted into the IC card connector. During the plugging and unplugging of the IC card, the IC card chip continuously rubs against the contact of the IC card connector, the friction stroke is long, the friction force is large, and the plastic body and the chip of the IC card often have large scratches and the surface metal layer is seriously worn. SUMMARY

[0004] In view of the situation that the IC card chip continuously rubs against the contact of the IC card connector during the plugging and unplugging of the IC card, the friction stroke is long, the friction force is large, and the IC card chip often has large scratches and the surface metal layer is seriously worn, the present application proposes an IC card connector to improve the situation. To this end, the present application adopts the following technical solutions.

[0005] An IC card connector includes an upper shell, a lower shell, an elastic contact end group, a rebounding piece, an upper sliding piece and a lower sliding piece.

[0006] The upper shell and the lower shell are connected to each other and surround a cavity capable of accommodating the front end of the IC card. The cavity has an insertion opening for the IC card to be adapted to be inserted.

[0007] The elastic contact end group is fixed to the upper shell. The elastic contact end group has a plurality of elastic contacts.

[0008] The rebounding piece is connected to the lower shell and the lower sliding piece at both ends. The lower sliding piece is connected to the upper sliding piece in linkage. The lower sliding piece or the upper sliding piece has a blocking surface facing the insertion opening. The blocking surface is located in the cavity. The upper sliding piece has a through hole. The through hole communicates with the cavity.

[0009] When the IC card is not inserted: the resilient member pulls the lower slide, the lower slide pushes against the upper slide, the upper slide is static against the upper shell, the upper slide also pushes the one end of the elastic contact terminal set upwards, the one end of the elastic contact terminal set is elastically deformed upwards, and the elastic contact is located in the through hole and downwards towards the lower shell and / or the lower slide.

[0010] When the IC card is inserted: the IC card pushes on the blocking surface, pushes the upper slide and the lower slide away from the insertion port synchronously, the resilient member is stretched, the upper slide weakens or removes the support of the elastic contact terminal set, the one end of the elastic contact terminal set rebounds downwards, and the elastic contact enters the cavity and can push on the chip of the IC card.

[0011] By adopting the technical scheme, the IC card connector allows the IC card to be inserted, and the elastic contact gradually presses on the IC card after the IC card abuts against the blocking surface. In this process, the pressure of the elastic contact on the IC card gradually increases until the elastic contact presses on the chip of the IC card. Overall, compared with the traditional contact clamping mode with a smaller spacing than the thickness of the IC card, the friction on the IC card is smaller, and the scratches on the plastic body and the chip of the IC card are smaller.

[0012] A preferred structure of the IC card connector is that the upper slide has a support slope, and the support slope leads to the through hole.

[0013] The one end of the elastic contact terminal set is bent downwards and then upwards to obtain a downward bending surface and an upward bending surface, and the junction of the downward bending surface and the upward bending surface is a lowest point, and the lowest point is the elastic contact.

[0014] When the IC card is not inserted, the support slope is attached to the downward bending surface to make the one end of the elastic contact terminal set elastically deformed upwards.

[0015] By adopting the technical scheme, the one end of the elastic contact terminal set elastically deformed upwards has a rebounding trend downwards, and after the upper slide is removed, the one end of the elastic contact terminal set rebounds downwards and can press on the IC card.

[0016] A preferred structure of the IC card connector is that the top of the upper slide has a spacing surface, and the spacing surface is horizontally connected to the upper end of the support slope. When the IC card is not inserted, the spacing surface and the elastic contact terminal set are not in contact.

[0017] By adopting the above technical scheme, after the upper slide moves, the supporting slope gradually releases the support on the elastic contact end group, the elastic contact end group will not be pressed on the top of the upper slide, the elastic contact end group has a space for continuously rebounding downward, so that the elastic contact gradually enters the cavity and can be pressed on the inserted IC card.

[0018] A preferred structure of the IC card connector is that the distance between the spacing surface and the bottom surface of the elastic contact end group is 1-5 mm when no IC card is inserted.

[0019] By adopting the above technical scheme, the distance can make the elastic contact end group have a moderate rebounding space, so that the elastic contact gradually enters the cavity and can be pressed on the inserted IC card.

[0020] A preferred structure of the IC card connector is that the upper housing is provided with an upper opening. The upper slide is installed in the upper opening.

[0021] The lower housing is provided with a lower opening. The lower slide is installed in the lower opening.

[0022] The IC card connector further comprises an upper cover plate and a lower cover plate. The upper cover plate is attached to the upper housing to block the upper slide, and the lower cover plate is attached to the lower housing to block the lower slide.

[0023] By adopting the above technical scheme, the above structure facilitates the installation of the upper slide and the lower slide, and supplements the support on the lower slide.

[0024] A preferred structure of the IC card connector is that the upper housing has a first lateral opening flat-bottom groove. The lower housing has a second lateral opening flat-bottom groove. The first flat-bottom groove and the second flat-bottom groove are located on opposite sides.

[0025] When no IC card is inserted: under the action of the rebounding force of the rebounding piece, one end of the upper slide away from the blocking surface is pressed on the inner side surface of the first flat-bottom groove, and the other end of the upper slide is loaded on the lower slide. The upper surface of the second flat-bottom groove supports one end of the lower slide away from the insertion port. The lower slide has a lower protruding column, and the lower cover plate supports the lower protruding column.

[0026] By adopting the above technical scheme, the upper slide and the lower slide are both supported.

[0027] A preferred structure of the IC card connector is that the upper slide has a blocking portion perpendicular to the upper housing. One side of the blocking portion facing the insertion port is the blocking surface.

[0028] The lower slide has a linkage portion perpendicular to the upper housing, and the linkage portion abuts on one side of the blocking portion away from the blocking surface.

[0029] By adopting the technical scheme, the upper slide and the lower slide can move back and forth in linkage and are easy to be disassembled from each other.

[0030] A preferred structure of the IC card connector is that one side of the upper housing facing the lower housing has a first inclined guide surface. One side of the lower housing facing the upper housing has a second inclined guide surface.

[0031] When the IC card is inserted, the upper slide is fitted to the first inclined guide surface and moves upward along the first inclined guide surface. The lower slide is fitted to the second inclined guide surface and moves upward along the second inclined guide surface.

[0032] By adopting the technical scheme, the upper slide and the lower slide can drive the internal IC card to move upward, further strengthen the abutting pressure of the elastic contacts, and enhance the effectiveness of the electrical connection.

[0033] A preferred structure of the IC card connector is that one side of the upper housing facing the lower housing further has a flat bottom surface. The first inclined guide surface is inclined upward based on the flat bottom surface. The flat bottom surface is closer to the insertion opening than the upper end of the first inclined guide surface.

[0034] The upper slide has a flat top surface and a first inclined sliding surface connected to each other. The first inclined sliding surface is inclined downward based on the flat top surface. The lower end of the first inclined sliding surface is closer to the insertion opening than the flat top surface.

[0035] When the IC card is not inserted, the flat top surface is fitted to the flat bottom surface. When the IC card is inserted, the first inclined sliding surface is fitted to the first inclined guide surface.

[0036] By adopting the technical scheme, when the IC card is inserted, the flat top surface slides over the flat bottom surface, the upper slide is relatively moved upward and is fitted to the upper housing, the length of the elastic contacts exposed from the bottom of the upper slide is more, that is, at this node, the contact between the elastic contacts and the IC card is suddenly enhanced, and before this, the friction between the IC card and the elastic contacts is small.

[0037] A preferred structure of the IC card connector is that the lower housing is provided with a plurality of sliding grooves, each of the sliding grooves has the second inclined guide surface. The lower slide has a plurality of sliding blocks, each of the sliding blocks has a second inclined sliding surface. When the IC card is not inserted, the second inclined sliding surface and the second inclined guide surface are arranged in a spaced manner. When the IC card is inserted, the second inclined sliding surface is fitted to the second inclined guide surface and moves upward along the second inclined guide surface.

[0038] By adopting the technical scheme, when the IC card is inserted, the second inclined sliding surface first approaches the second inclined guide surface and then moves upward along the second inclined guide surface, so as to lift the IC card and strengthen the pressure on the elastic contacts.

[0039] In summary, the IC card connector of this application has the following beneficial effects: the IC card connector allows the IC card to be inserted. After the IC card comes into contact with the blocking surface, the elastic contacts gradually press down on the IC card. During this process, the pressure of the elastic contacts on the IC card gradually increases until the elastic contacts press on the IC card chip. Overall, compared with the traditional contact clamping method that uses a contact spacing smaller than the IC thickness, this method causes less friction on the IC card and fewer scratches on the plastic body and chip of the IC card.

DETAILED DESCRIPTION

[0052] The present application is further described below in conjunction with the accompanying drawings.

[0053] As Figure 1 , an IC card connector includes an upper housing 1, a lower housing 2, an elastic contact terminal set 3, a spring 4, an upper slide 5, and a lower slide 6.

[0054] As Figure 2 , the upper housing 1 and the lower housing 2 are connected to each other by a snap fit and enclose a flat cavity 7 capable of accommodating the front end of an IC card. The cavity 7 has an insertion port 8 for the IC card to be fitted.

[0055] As Figure 3 , a dust plug 9 that can be pulled out is also inserted into the insertion port 8.

[0056] As Figure 4 , the elastic contact terminal set 3 is fixed to the upper housing 1.

[0057] As Figure 5 , the elastic contact terminal set 3 has a plurality of elastic contacts 301. Specifically, the elastic contact terminal set 3 includes eight metal strips, each of which passes through the upper housing 1 in parallel and is fixed by the upper housing 1. One end of the metal strip protrudes out of the upper housing 1 to become a pin. The other end of the metal strip extends inwardly to form an elastic contact 301 by being bent downward, forming two rows of elastic contacts 301, four in each row.

[0058] As Figure 6 , the spring 4 has its two ends connected to the lower housing 2 and the lower slide 6. The spring 4 can be a spring.

[0059] As Figure 7 , the lower slide 6 is connected to the upper slide 5 in linkage. The lower slide 6 or the upper slide 5 has a blocking surface 5041 facing the insertion port 8. The blocking surface 5041 is located in the cavity 7.

[0060] As Figure 8 The upper slide 5 has a through hole 501. The through hole 501 communicates with the cavity 7.

[0061] The upper slide 5 and the lower slide 6 can be sheet structures, but can be provided with a porous structure to facilitate supporting the elastic contact terminal group 3 with the upper slide 5. The lower slide 6 is provided with a hole for accommodating the spring.

[0062] When the IC card is not inserted: the resilient member 4 pulls the lower slide 6 by elastic force, the lower slide 6 abuts against the upper slide 5, the upper slide 5 abuts against the upper housing 1 and is stationary, the upper slide 5 also abuts against one end of the elastic contact terminal group 3, so that one end of the elastic contact terminal group 3 is elastically deformed upward, and the elastic contact 301 is located in the through hole 501 and downwardly faces the lower housing 2 and / or the lower slide 6.

[0063] It should be noted that downward in the present application refers to the direction upwardly facing the upper housing 1, and downward refers to the direction downwardly facing the lower housing 2.

[0064] When the IC card is inserted: the IC card abuts against the blocking surface 5041 and pushes the upper slide 5 and the lower slide 6 away from the insertion opening 8 synchronously, the resilient member 4 is stretched, the upper slide 5 weakens or releases the support for the elastic contact terminal group 3, one end of the elastic contact terminal group 3 rebounds downwardly, so that the elastic contact 301 enters the cavity 7 and can abut against the chip of the IC card.

[0065] The IC card connector allows the elastic contact 301 to gradually press on the IC card after the IC card abuts against the blocking surface 5041 during the insertion of the IC card. During this process, the pressure of the elastic contact 301 on the IC card gradually increases until the elastic contact 301 presses on the chip of the IC card. Overall, compared with the conventional contact clamping mode with a spacing less than the thickness of the IC card, the present mode has less friction on the IC card and causes less scratches on the plastic body and the chip of the IC card.

[0066] The upper slide 5 has a support inclined surface 502, which leads to the through hole 501, i.e. guides the through hole 501 along the support inclined surface 502. In order to adapt to the eight metal strips of the elastic contact terminal group 3, the support inclined surface 502 should specifically be eight identical sub-inclined surfaces, and correspondingly, the through hole 501 should be eight sub-holes for accommodating the eight elastic contacts 301.

[0067] As Figure 5, the one end of the elastic contact end group 3 is bent downward and then upward, and the downward bending surface and the upward bending surface are connected to form a lowest point, and the lowest point is the elastic contact point 301. When the IC card is not inserted, the support inclined surface 502 is attached to the downward bending surface, so that the one end of the elastic contact end group 3 is elastically deformed upward. In the above structure, the one end of the elastic contact end group 3, which is forced to be elastically deformed upward, has a tendency to rebound downward, and after the upper slider 5 is removed, the one end of the elastic contact end group 3 rebounds downward, so as to be pressed on the chip of the IC card.

[0068] As shown in Figure 8 , the top of the upper slider 5 has a spacing surface 503, which is a plane, and the spacing surface 503 is horizontally connected to the upper end of the support inclined surface 502. When the IC card is not inserted, the spacing surface 503 is not in contact with the elastic contact end group 3. The reason for the above arrangement is that after the upper slider 5 is translated, the support inclined surface 502 gradually releases the support of the elastic contact end group 3, and because the spacing surface 503 is not in contact with the elastic contact end group 3, the elastic contact end group 3 will not be immediately pressed on the top of the upper slider 5, or will never be pressed on the top of the upper slider 5 without external interference, so that the elastic contact end group 3 has a space for continuous rebounding downward, so that the elastic contact point 301 gradually enters the cavity 7 and can be pressed on the inserted IC card.

[0069] For the case that when the IC card is not inserted, the spacing surface 503 is not in contact with the elastic contact end group 3, some optional situations are that the distance between the spacing surface 503 and the bottom surface of the elastic contact end group 3 is 1-5mm, for example, 3mm. The distance can make the elastic contact end group 3 have a moderate rebounding space, so that the elastic contact point 301 gradually enters the cavity 7 and can be pressed on the inserted IC card.

[0070] The upper housing 1 is provided with an upper opening 101. The upper slider 5 is installed in the upper opening 101. The lower housing 2 is provided with a lower opening 201. The lower slider 6 is installed in the lower opening 201. The IC card connector further comprises an upper cover plate 10 and a lower cover plate 11. The upper cover plate 10 can be attached to the upper housing 1 by glue to block the upper slider 5, and the lower cover plate 11 can be attached to the lower housing 2 by glue to block the lower slider 6. The above structure not only facilitates the installation of the upper slider 5 and the lower slider 6, but also supplements the support of the lower slider 6.

[0071] As shown in Figure 1To enhance the support for the upper sliding member 5 and the lower sliding member 6 and improve their stability, the upper housing 1 has a first flat-bottomed groove 102 with a lateral opening. The lower housing 2 has a second flat-bottomed groove 202 with a lateral opening. The first flat-bottomed groove 102 and the second flat-bottomed groove 202 are located on opposite sides. When no IC card is inserted: under the pulling force of the spring-loaded member 4, one end of the upper sliding member 5 away from the blocking surface 5041 rests against the inner side of the first flat-bottomed groove 102, and the other end of the upper sliding member 5 is mounted on the lower sliding member 6. The upper surface of the second flat-bottomed groove 202 supports the end of the lower sliding member 6 away from the insertion port 8. The lower sliding member 6 has a lower protrusion 601, which is supported by the lower cover plate 11. This structure effectively supports both the upper sliding member 5 and the lower sliding member 6.

[0072] The aforementioned sliding member 6 or sliding member 5 has a blocking surface 5041 facing the insertion port 8. In one specific case, the sliding member 5 has a blocking portion 504 perpendicular to the upper housing 1, with the side of the blocking portion 504 facing the insertion port 8 being the blocking surface 5041. The sliding member 6 has a linkage portion 602 perpendicular to the upper housing 1, abutting against the side of the blocking portion 504 facing away from the blocking surface 5041. In this specific case, the sliding member 5 provides the blocking surface 5041, and the sliding member 5 and sliding member 6 can move back and forth in linkage, and they are easily detached from each other. The blocking portion 504 can be a downward-facing horizontal plate. The linkage portion 602 can be an upward-facing horizontal plate.

[0073] like Figure 9 The upper housing 1 has a first inclined guide surface 103 on the side facing the lower housing 2. The lower housing 2 has a second inclined guide surface 203 on the side facing the upper housing 1. When an IC card is inserted, the upper sliding member 5 is attached to the first inclined guide surface 103 and moves upward along the first inclined guide surface 103; the lower sliding member 6 is attached to the second inclined guide surface 203 and moves upward along the second inclined guide surface 203. The upper sliding member 5 and the lower sliding member 6 can then drive the internal IC card upward, further strengthening the contact pressure with the elastic contact 301 and enhancing the effectiveness of the electrical connection between the IC card and the elastic contact 301.

[0074] like Figure 9 To maintain the movement of the upper sliding piece and the elastic contact end assembly 3 under a certain contact pressure, the upper housing 1 can be used to restrict the vertical and horizontal movement of the upper sliding piece. The side of the upper housing 1 facing the lower housing 2 is also designed to have a flat bottom surface 104. The first inclined guide surface 103 is inclined upwards based on the flat bottom surface 104. The upper end of the flat bottom surface 104 is closer to the insertion port 8 than the upper end of the first inclined guide surface 103.

[0075] As Figure 8 , the upper slide 5 has a flat top surface 505 and a first inclined sliding surface 506 connected to each other. The first inclined sliding surface 506 is inclined downward based on the flat top surface 505. The lower end of the first inclined sliding surface 506 is closer to the insertion port 8 than the flat top surface 505.

[0076] When the IC card is not inserted, the flat top surface 505 abuts against the flat bottom surface 104. When the IC card is inserted, the first inclined sliding surface 506 abuts against the first inclined guide surface 103.

[0077] In the above design, when the IC card is not inserted in the IC card connector, the upper slide 5 deforms against the elastic contact terminal set 3. When the IC card is inserted, during the sliding process of the upper slide 5 in the upper housing 1, after the flat top surface 505 slides over the flat bottom surface 104, the upper slide 5 moves upward relative to the upper housing 1 and abuts against the upper housing 1. The elastic contact terminal set 3 rebounds downward, and the elastic contact 301 exposes more length from the bottom of the upper slide 5. That is, at this node, the contact between the elastic contact 301 and the IC card suddenly increases, and before this, the friction between the IC card and the elastic contact 301 is small.

[0078] As Figure 10 , as described above, when the IC card is inserted, the lower slide 6 abuts against the second inclined guide surface 203, and the lower slide 6 moves upward along the second inclined guide surface 203. A specific structure for achieving this process is that the lower housing 2 is provided with a plurality of sliding grooves 204, and each sliding groove 204 has the second inclined guide surface 203. Figure 11 The lower slide 6 has a plurality of sliding blocks 603, and each sliding block 603 has a second inclined sliding surface. When the IC card is not inserted, the second inclined sliding surface is spaced apart from the second inclined guide surface 203. When the IC card is inserted, the second inclined sliding surface abuts against the second inclined guide surface 203 and moves upward along the second inclined guide surface 203. For the above structure, when the IC card is inserted, the second inclined sliding surface first approaches the second inclined guide surface 203, and then moves upward along the second inclined guide surface 203, thereby lifting the IC card to increase the pressure on the elastic contact 301.

[0079] As Figure 1 , in addition to the above structure, the IC connector further includes a grounding metal strip 12 and a micro switch 13. The grounding metal strip 12 is embedded in the lower housing 2 and is used to discharge static electricity. The micro switch 13 is installed on the inner surface of the upper housing 1, and the micro switch 13 is used to detect whether the IC card is inserted. In the absence of the IC card, the micro switch 13 is in an open state; when the card is inserted, the micro switch 13 on the IC card seat is closed, thereby triggering the closure of the circuit, so that the system can recognize the presence of the IC card.

[0080] The above merely provides the preferred embodiments of the present application, and is not intended to limit the protection scope of the present application. For those skilled in the art, various equivalent substitutions and modifications can be made according to the above description, and these substitutions and modifications should be covered in the protection scope of the present application.
