Description

IC card seat assembly and POS equipment

Technical Field

The utility model relates to a POS equipment that is used for IC card seat subassembly of POS equipment and includes this subassembly.

Background

With the development of technology, IC cards are widely used in the financial, traffic, medical, identification and other industries, and the communication between an IC Card and a reader/writer may be contact or non-contact.

Generally, an IC card socket is integrated on a circuit board of an IC card reader/writer, and contacts intended to be electrically connected to the contacts of the IC card chip are provided on the IC card socket. At present, the arrangement modes of the IC card seat are mainly two. A full-sized IC card holder includes a base plate, a top cover and a side wall connecting them, and contacts are provided inside the IC card holder defined by these portions. Full-size IC card seat is generally produced by full-automatic equipment, and the advantage is that the precision is high and the quality is reliable. However, the term "full size" means that the length of the bottom plate at the insertion end of the IC card is at least equal to the width of the IC card. It can be understood that the IC card socket occupies a large area on the circuit board. To solve this problem, another IC card holder removes most of the area of the chassis, leaving only the portion provided with the contacts. The space saved in this way can be used for placing other devices, which is beneficial to reducing the area of the circuit board or increasing the use area of the circuit board. However, the bare seat type IC card seat is not an integrated component, and usually needs to be designed and matched with the structure as required, and an IC card limiting structure needs to be additionally arranged on the card reader, so that the design cost is additionally increased, and the integration level of the circuit board is reduced.

Moreover, both of the above IC card holders do not provide satisfactory solutions when the thickness of the IC card reader is required to be as small as possible. The full-size IC card seat comprises a bottom plate and a top cover, and the whole thickness of the full-size IC card seat is larger; although the top cover of the bare seat type IC card seat is removed, the thickness of the bottom plate of the bare seat type IC card seat is still not negligible.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to solve the above problems in the prior art, and provides an IC card holder assembly for an ultra-thin IC card reader/writer, especially an ultra-thin POS (Point of Sale) device, which can ensure the electrical connection of an IC card and a circuit board within a small thickness range.

Therefore, the utility model provides a IC-card seat subassembly for POS equipment, including the circuit board and with the IC-card seat that the circuit board electricity is connected, the IC-card seat includes the bottom plate and sets up on the bottom plate and aim at the contact with IC-card electric connection, its characterized in that, be equipped with the through-hole in the circuit board, the bottom plate is located at least partially in the thickness direction within the through-hole, the contact salient is in the upper surface of circuit board.

Thus, the sunken plate type IC card seat component is formed by arranging a through hole in the circuit board and embedding the bottom plate of the IC card seat into the through hole. It can be understood that at least a part of the thickness of the base plate of the IC card holder coincides with the thickness of the circuit board, thereby reducing the overall thickness of the IC card holder assembly and thus the overall thickness of the overall POS device, which contributes to the slimness of the POS device. Furthermore, according to the utility model discloses, still guarantee when the bottom plate of IC-card seat sinks in the circuit board that its contact that aims at being connected with IC-card electricity surpasss circuit board surface to guarantee can touch the contact on the IC-card chip after the IC-card inserts, realize the intercommunication of circuit.

According to a preferred embodiment of the present invention, the bottom plate includes an insertion portion, a planar dimension of the insertion portion is identical to a planar dimension of the through hole, and the insertion portion is engaged with the through hole. In other words, the base plate may be designed to be only partially embedded in the circuit board, and the thickness of the other portions may be designed to be small so that it is the same as the thickness of the insertion portion after being superimposed with the thickness of the circuit board. This smaller thickness portion may be used to further secure the base plate to the circuit board, for example by gluing or soldering. The insertion part is directly inserted into the through hole to form fixed connection, for example, the insertion part can be in interference fit without other fixing modes, so that the production process is simplified, and the production efficiency is improved. For this reason, the planar size of the insertion portion may be designed to be slightly larger than that of the through-hole, but those skilled in the art will appreciate that such a degree of dimensional difference also falls within the aforementioned "dimensional uniformity". Of course, the clamping can also be combined with other fixing methods to achieve a more firm effect, such as fixing other parts of the bottom plate to the circuit board at the same time, or adhering the insertion part to the through hole, and the like. In these cases, the planar dimension of the insertion portion may also be equal to or slightly smaller than the planar dimension of the through hole, and of course, this degree of dimensional difference also falls within the aforementioned "dimensional uniformity" range.

According to a preferred embodiment of the present invention, a bottom surface of the insertion portion protrudes from a lower surface of the circuit board. Therefore, the top surface of the IC card seat can be closer to the upper surface of the circuit board, and the contact of the IC card seat is closer to other contacts on the surface of the circuit board under the condition of requirement. Alternatively, the bottom surface of the insertion portion may be flush with the lower surface of the circuit board. Therefore, the circuit board can be conveniently arranged in the POS equipment, and the bottom plate of the IC card seat does not additionally occupy the space of the equipment below the circuit board, so that the flexible layout of the card seat component in the POS equipment is facilitated.

According to a preferred embodiment of the present invention, the IC card holder includes a pin soldered to an upper surface or a lower surface of the circuit board. The pins are welded on the circuit board, so that the electric connection between the IC card seat and the circuit board is realized, the mechanical fixation between the IC card seat and the circuit board is realized, and the integrated mode is convenient and saves cost.

According to a preferred embodiment of the present invention, the IC card holder does not include a top cover. In other words, the IC card seat itself can be a deformation of the bare seat type IC card seat in the prior art, and since the IC card seat does not include the top cover, the thickness of the IC card seat itself can be reduced to the maximum extent, so as to further reduce the overall thickness of the IC card seat assembly, which is beneficial to the light and thin design of the POS device. Of course, the IC card socket can also adopt a full-size IC card socket including a top cover in the prior art, so as to provide higher precision and safety performance.

The utility model discloses still relate to a POS equipment, it includes as above IC-card seat subassembly, POS equipment still include with IC-card seat complex IC-card spacing portion. Therefore, the IC card seat can not comprise an IC card limiting part, such as a top cover or a side wall, but still ensure that the IC card can be smoothly inserted into a designated position in the POS equipment, so that the contact of the chip of the IC card seat is accurately contacted with the contact on the IC card seat, and the electric connection is realized.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.

It is to be understood by those skilled in the art that these drawings are solely for purposes of illustration and are not intended as a definition of the limits of the invention. The same reference numbers in the drawings identify the same or similar elements. For purposes of illustration, the figures are not drawn to scale.

Detailed Description

It is understood by those skilled in the art that the following examples are only for the purpose of more clearly describing the technical solutions of the present invention, and do not limit the scope of the present invention in any way.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

First, the cross section of each drawing is perpendicular to the parallel board along the card insertion direction (arrow A on the right side in the drawing). Fig. 1 shows a prior art full-sized IC card socket 2 which is fixed on a PCB (i.e. a circuit board) and soldered to the PCB by means of built-in pins 7. The IC card holder 2 includes a base plate 6 and a top cover 5, and the contacts 4 are disposed inside the IC card holder 2 defined by both. In use, the IC card 3 is inserted in direction a into the area defined by the base plate 6 and the top cover 5, and electrical connection is made by contact of its chip with the contacts 4. The overall thickness of the IC card holder 2 is large, typically 3mm to 6mm, and often 4mm for example, which obviously is not favorable for realizing an ultra-thin POS device.

Figure 2 shows a prior art bare-seated IC card holder 2 with most of the area of the top cover 5 and bottom plate 6 of the full-sized IC card holder removed, leaving only the portion provided with contacts 4. The IC card holder 2 is also fixed on the PCB and is welded with the PCB through the built-in pins 7. However, the thickness of the bottom plate 6 is relatively large, usually 1.5 to 4mm, and the thickness of a circuit board commonly used in the POS device is about 1.5mm, so that even a bare-seat type IC card seat can significantly increase the thickness of the card seat assembly, which is not favorable for realizing an ultra-thin POS device.

Fig. 3 schematically shows an IC card holder assembly 1 according to an embodiment of the present invention, including a circuit board 10 and an IC card holder 20. The IC card socket 20 is fixed and electrically connected to the circuit board 10, for example, by soldering the pins 26 to the upper surface 14 of the circuit board 10. The IC card holder 20 includes a base 22 and contacts 24 provided on the base 22. The contacts 24 may be plural and protrude from the upper surface 14 of the circuit board 10 such that: when the IC card 30 is inserted into the POS device, its chip is electrically connected to the contacts 24. The circuit board 10 is provided therein with a through-hole 12, and the through-hole 12 divides the circuit board 10 into two parts, left and right, as shown in the sectional view of fig. 3. The through holes 12 may be formed by any suitable technique, such as hollowing or hollowing, through the circuit board 10. The bottom plate 22 of the IC card holder 20 is located at least partially within the through-hole 12 in the thickness direction.

In other words, the sunk plate type IC card holder assembly is formed by providing the through hole 12 in the circuit board 10 and fitting the bottom plate 22 of the IC card holder 20 into the through hole 12. Since at least a part of the thickness of the IC card holder base plate 22 coincides with the thickness of the circuit board 10, the overall thickness of the IC card holder assembly 1 is reduced, which contributes to the light and thin design of the POS device. In addition, the bottom plate 22 of the IC card socket 20 is sunk into the circuit board 10 while ensuring that the contacts 24 thereof are beyond the upper surface 14 of the circuit board, so as to ensure that the contacts on the IC card chip can be contacted after the IC card 30 is inserted, thereby realizing the circuit connection.

Since the cross-section of fig. 3 is through the through-hole 12, the bottom plate 22 shows only the insertion portion 220. The bottom plate 22 may include portions other than the insert portion, such as edges, to further secure it to the circuit board 10. Preferably, the planar dimension of the insert portion 220 substantially corresponds to the planar dimension of the through hole 12, so as to clamp the insert portion 220 in the through hole 12, for example, by interference fit, so as to enhance the fixation therebetween.

In the embodiment shown in fig. 3, the bottom surface 224 of the insert portion 220 extends beyond the lower surface 16 of the circuit board 10, so that the top surface of the IC card socket 20 is closer to the upper surface 14 of the circuit board 10, and the contacts 24 of the IC card socket 20 are closer to other contacts on the surface of the circuit board 10.

In contrast, in the embodiment shown in fig. 4, the bottom surface 224 of the insertion portion 220 is flush with the lower surface 16 of the circuit board 10. In this way, the circuit board 10 can be conveniently arranged in the POS device, because the bottom plate 22 of the IC card socket does not additionally occupy the space of the device below the circuit board 10, which is beneficial to the flexible layout of the card socket assembly in the POS device.

Further, it is also different from the embodiment shown in fig. 3 in that, in the embodiment shown in fig. 4, the pins 26 of the IC card socket 20 are soldered to the lower surface 16 of the circuit board 10. The pins are welded on the circuit board, so that the electric connection between the IC card seat and the circuit board is realized, the mechanical fixation between the IC card seat and the circuit board is realized, and the integrated mode is convenient and saves cost. Whether it is soldered to the upper surface or the lower surface of the circuit board can be selected according to the actual situation.

As shown in fig. 3 and 4, preferably, the IC card socket 20 according to the present invention does not include a top cover. Therefore, the thickness of the IC card seat can be reduced to the maximum extent, the overall thickness of the IC card seat assembly is further reduced, and the light and thin design of POS equipment is facilitated. However, if necessary, the IC card holder may also adopt a full-sized IC card holder of the related art, including a top cover and a bottom plate, to provide higher precision and safety.

The present invention also relates to a POS device (not shown) comprising the IC card holder assembly 1 as described above, the POS device further comprising an IC card retainer (not shown) engaged with the IC card holder 20. Therefore, the IC card seat does not comprise an IC card limiting part, such as a top cover or a side wall, and the IC card can be still ensured to be smoothly inserted into a specified position in the POS equipment, so that the contacts of the chip of the IC card seat accurately contact with the contacts on the IC card seat to realize electric connection.

The drawings and the foregoing description depict non-limiting specific embodiments of the invention. For the purpose of teaching inventive principles, some conventional aspects have been simplified or omitted. Those skilled in the art will appreciate variations from these embodiments that fall within the scope of the invention. Those skilled in the art will appreciate that the above-described features can be combined in various ways to form multiple variations of the invention. Accordingly, the present invention is not limited to the specific embodiments described above, but is only limited by the claims and their equivalents.
