Abstract

The utility model provides a POS machine touch -sensitive screen safety is prevented dismouting and is put, including casing, capacitive touch panel and carbon granules contact, capacitive touch panel fixed mounting is in in the casing, just the casing is pushed down around capacitive touch panel's the surface, capacitive touch panel's bottom surface laminating has thin film conductor wire winding layer, carbon granules contact place respectively in four summit departments of capacitive touch panel bottom surface, and at each draw forth two wires on the carbon granules contact respectively jointly around full whole thin film conductor wire winding layer and with each carbon granules contact interconnect. The utility model has the advantages of, can prevent that lawless persons carries out the illegality to capacitive touch panel and demolishs, can prevent again that it from cutting the change to capacitive touch panel to make the capacitive touch panel of POS machine obtain safer protection, guarantee user's transaction safety.

Description

The safe antiwithdrawal device of a kind of POS touch-screen

Technical field

The utility model relates to POS field, more particularly, relates to the safe antiwithdrawal device of a kind of POS touch-screen.

Background technology

POS is a kind of point-of-sale terminal with clearing of account function, is widely used in the places such as supermarket, chain store, hypermarket, restaurant.Because relate to the transaction of bank card, so have very high requirement to its security performance, must ensure that significant data such as the key etc. inside POS is not stolen.

Current POS more and more screen enlarging; a lot of machine also tends to the input using touch-screen input as safety keyboard; for preventing lawless person, touch-screen is attacked to obtain the important information such as trading password of user of swiping the card, so require that POS deviser will carry out strict safeguard protection to touch-screen.

Summary of the invention

The technical problems to be solved in the utility model; be to provide a kind of POS touch-screen safe antiwithdrawal device; can prevent lawless person from illegally removing capacitance touch screen; can prevent from again it from carrying out cutting to capacitance touch screen to change; thus make the capacitance touch screen of POS obtain safer protection, ensure the transaction security of user.

The utility model is achieved in that the safe antiwithdrawal device of a kind of POS touch-screen, comprise casing, capacitance touch screen and carbon granules contact, described capacitance touch screen is fixedly mounted in described casing, and described casing pushes down the surperficial surrounding of described capacitance touch screen, the bottom surface of described capacitance touch screen is fitted with a thin film conductor wire winding layer, described carbon granules contact is positioned over four summits place of described capacitance touch screen bottom surface respectively, and on each described carbon granules contact, to draw two wires respectively jointly around completely whole described thin film conductor wire winding layer, each described carbon granules contact is interconnected.

Preferably, each described wire all carries out coiling in snakelike trend and coiling width between each described wire and spacing are all no more than 6mil on described thin film conductor wire winding layer.

Preferably, described thin film conductor wire winding layer is transparent membrane conductor wire winding layer.

After adopting such scheme, the utility model tool has the following advantages:

1, first prevent from removing to capacitance touch screen and protect: capacitance touch screen adopts built-in type to be fixed in casing, and surface is pushed down by casing, capacitance touch screen is withstood by carbon granules contact in bottom, so just capacitance touch screen is clipped in POS and is not removed, if move capacitance touch screen, then four carbon granules contacts capacitance touch screen can pressed below separate with capacitance touch screen, cause triggering, POS will carry out self-protection, and complete machine was lost efficacy;

2, next prevents lawless person from carrying out cutting destruction to capacitance touch screen: if lawless person is by cutting capacitance touch screen, region in the middle of capacitance touch screen is cut off, and then change the capacitance touch screen of an implanted wooden horse, also can cause damage to user, so stick the thin film conductor wire winding layer of layer of transparent on the bottom surface of capacitance touch screen, (transparent thin film conductor wire winding layer both can not impact LCD sight line, capacitance touch screen can be protected again), the wire of being drawn by four carbon granules contacts is carried out safeguard protection coiling and is interconnected each carbon granules contact, capacitance touch screen is protected, coiling will be caused to be damaged if cut capacitance touch screen, connection then between each carbon granules contact disconnects, cause triggering, POS carries out self-protection, complete machine was lost efficacy.

Accompanying drawing explanation

The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the upward view (only showing the thin film conductor wire winding layer of local in figure) of the utility model embodiment capacitance touch screen bottom surface.

Embodiment

Refer to Fig. 1 and Fig. 2, the safe antiwithdrawal device of a kind of POS touch-screen of the present utility model comprises casing 1, capacitance touch screen 2 and carbon granules contact 3, described capacitance touch screen 2 is fixedly mounted in described casing 1, and described casing 1 pushes down the surperficial surrounding of described capacitance touch screen 2, the bottom surface of described capacitance touch screen 2 is fitted with a thin film conductor wire winding layer 21, described carbon granules contact 3 is positioned over four summits place of described capacitance touch screen 2 bottom surface respectively, and on each described carbon granules contact 3, draw that two wires 31 are common to be interconnected each described carbon granules contact 3 around completely whole described thin film conductor wire winding layer 21 respectively.

Again as shown in Figure 2, the utility model one preferred embodiment is (being not limited to the coiling trend in Fig. 2 on thin film conductor wire winding layer):

Each described wire 31 all on described thin film conductor wire winding layer 21, carries out coiling in snakelike trend and coiling width (not shown) between each described wire 31 and spacing H are all no more than 6mil.Described thin film conductor wire winding layer 21 is transparent membrane conductor wire winding layer; Transparent thin film conductor wire winding layer 21 both can not impact LCD sight line, can protect capacitance touch screen 2 again.

The utility model; by casing and carbon granules contact to the physical protection of capacitance touch screen; capacitance touch screen is prevented to be removed; the wire of simultaneously being drawn by each carbon granules contact again carries out safe coiling on thin film conductor wire winding layer; avoid the cut replacing of capacitance touch screen; jointly being protected by both to make the security of POS capacitance touch screen be improved, and ensures the transaction security of user.

The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
