Description

Lock connection device for computer

The present invention relates to a device for accessing a lock using a computer, and in particular, a lock connected in series from the outside of the computer is connected to the host boards in parallel to each other and embedded inside the computer, and whether the lock is normally connected. The present invention relates to a computer lock access device that can be easily identified from the outside.

In general, various programs are implemented by program makers to prevent unauthorized copying of programs used in computers.

In other words, there is a software lock in which a program having a special code system is put in a computer program, and a lock accompanied by hardware for connecting a terminal in the form of a connector to a printer port of a computer main body.

The pure software lock described above is inferior in security and is insufficient to protect expensive programs because it is possible to solve the cryptographic system.

Therefore, most expensive programs use locks involving hardware, which will be described later. In the present specification, locks refer to hardware.

However, the lock according to the prior art as described above has a problem that it is difficult to manage the lock as it is connected to and used in the printer port of the computer main body as illustrated in FIG.

That is, there is a high possibility that the lock L may be damaged or lost by being exposed to the outside of the computer, and when such a case occurs, a problem arises in that an expensive program cannot be used.

In addition, when a user uses a plurality of programs at the same time, the locks of the corresponding programs must be connected in series, so that the damage caused by the weight of the lock and the extension of the connection are prolonged. There is an even higher closure.

Of course, these locks can be used while the user keeps them securely in a random place and removes them whenever necessary, but in this case, the connection parts (pins and sockets) of the lock may be worn and expanded, causing malfunctions due to incorrect connection of the locks. Phosphorus desorption is undesirable.

This lock is provided by the manufacturer to protect the expensive program, but the user has a problem that the risk of damage and loss.

On the other hand, educational institutions that educate the program to distribute the lock to match the computer on which the program is installed, and when the training is terminated and stored, which is also a problem of high risk of loss and damage.

Accordingly, the present invention has been made in order to easily install and use a lock to protect expensive programs, and has the following object.

The present invention provides a lock connection device for a computer, which is provided with a lock connection device, which is a board for connecting a plurality of locks, and is incorporated in a computer so that there is no fear of damage or loss.

SUMMARY OF THE INVENTION The present invention provides an easy-to-manage computer lock connection device having an indicator that allows a plurality of connected locks to be identified from outside the computer to confirm the presence or absence of a lock.

The present invention provides a lock connection device for a computer which can detect a large number of connected locks with an extremely simple circuit, without the risk of failure and malfunction.

The present invention to achieve the above object is to be connected to the printer port by connecting a plurality of lock connection connectors in parallel to an appropriate PCB that can be embedded in a computer and both ends of the lock connection connector It is provided with the LED which detects the presence or absence of lock, and the drive circuit which drives this LED.

In order to detect and display the locks as described above, the present inventors have experimented with various detection circuits.

For example, the circuit was configured to detect the lock signal, and various hardware implementations were performed to detect and display the operation between the lock and the computer. Since the lock is uniquely maintained by each manufacturer, it is difficult to experiment with the entire lock. There was a problem that a technical configuration that completely eliminated the malfunction was difficult, and the circuit configuration was complicated.

Therefore, the inventors of the present invention have conducted a lot of experiments to achieve a simple circuit configuration capable of easily mounting a plurality of locks while easily detecting the presence or absence of any lock on any type of data line.

Among them, the simplest and widest range of locks and the lock detection device with accurate detection of locks have been invented.

CON. CON1-5: Connector LED1-5: Light Emitting Diode

Ra, R1-5: Resistor L: LOCK

Hereinafter, the technical spirit of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the connecting device of the present invention connects a plurality of locks (CON1-CON5) in parallel to each other so as to be connected to the printer port as a connector (CON) and operates in an expansion slot of a computer. (Vcc) is connected to each of the light emitting diodes (LED1-LED5) through a resistor array (R1-R5) in parallel with a resistor (Ra), but the metal shield of the lock between each of the light emitting diodes (LED1-LED5) and the ground terminal It is to be made into the lungs.

According to the present invention described above can be implemented as shown in FIG.

It forms a plurality of lock connection connectors (CON1-CON5) on the PCB 12 having coupling holes 10 coupled to the expansion slots of the computer and coupled to the enclosure, and the connectors are connected to the printer port connection (CON). ) Are connected in parallel to each other, but the light emitting diodes (LED1-LED5) are formed in the same number as the connector (CON1-CON5) in the coupler (10).

On the other hand, in order to accommodate a large number of locks in the lock connecting device, as shown in FIG. 4, another PCB 12a identical to the PCB 12 having the connector is formed, and these two PCBs ( 12 and 12a may be connected in parallel to each other.

Looking at the effects of the present invention as described above in more detail as follows.

In the present invention, since the basic data communication of the lock is inputted to the printer port as it is as a connector (CON), the unique operation of each lock is guaranteed.

At this time, the lock connection device of the present invention is mounted in the expansion slot of the computer receives the operating power (Vcc) from the slot.

At this time, if a predetermined lock is inserted into the connector CON1-CON5, the connector forms a circuit configuration in which both ends of the connector L are closed due to the metallic silicide case 30 of the lock L. (See FIG. 2B.)

That is, the operating power supply Vcc of FIG. 2 constitutes the ground circuit of the light emitting diode via the resistor Ra and the drive array.

Therefore, the connector into which the lock is inserted turns on the light emitting diode, and the user can easily identify whether or not the lock is normally installed outside the computer.

The present invention is simple to install, while preventing the loss or damage of the lock by allowing a large number of locks to be mounted inside the computer to prevent unauthorized use of expensive programs.

Of course, the combination of the lock is possible in any of the connectors (CON1-CON5), if you want to increase the installation of the lock to form a plurality of PCB (12, 12a) described above to form a parallel connection between the PCB ( 20) may be used in multiples by joining the PCB.

According to the present invention as described above, it is possible to incorporate the lock into a computer to be used for elimination of damage and loss, eliminating the need for a small insertion, there is no erroneous connection of the connection and can easily identify the combination of the lock as a light emitting diode from the outside It is a very useful invention having this effect and realizing it by an extremely simple circuit configuration.

Lastly, the present invention is not only mounted inside the computer but also may be formed as an external type installed in a separate casing and installed on the outside. Such modifications are merely very easy based on the technical idea of the present invention.
