Description

USB security gender {USB security gender}

The present invention relates to a USB gender, and more particularly, to a USB security gender suitable for enabling free use of general standard USB devices while enhancing security.

In general, USB (Universal Serial Bus) refers to a bus standard for connecting personal computers (PCs) and peripheral devices, and refers to an interface means for connecting computers and external devices.

USB like this can easily connect external devices to a computer without opening the computer. For example, USB has the advantage of easily connecting/disconnecting external devices such as printers, modems, scanners, digital cameras, and memory using a combination of standard ports and plugs. Among them, a representative means of external memory used by connecting USB to a computer is a USB memory stick, which is simply called USB or USB memory.

Recently, with the development of semiconductor and computing technology, memory means for data storage management are being developed in various forms, and various types of external memory devices are being commercialized, ranging from general hard disk drives (HDDs) to external memory devices with relatively small capacities such as CDs, DVDs, external hard drives, and various types of memories to high-capacity external memory devices that exceed the capacity of existing hard disk drives. Among these, USB memory is popular because it is small, easy to carry, and can be used by simply attaching it to the USB (Universal Serial Bus) terminal of a personal computer.

In addition to USB memory, there are various other devices that utilize this USB communication standard, such as USB mice, USB keyboards, USB vision equipment, USB cameras, and USB hubs.

In order to block these common USB devices from accessing data storage devices such as PCs, a security device called a USB blocking block was installed in the USB port.

However, in the past, when a USB blocking block was installed in a computer (data storage device), data backup or input had to be done only using a specially-made USB device compatible only with the USB blocking block, which caused great inconvenience in use.

That is, it was very inconvenient because it was impossible to freely use general standard USB devices.

The present invention was created to solve the problems of the above-mentioned prior art, and the purpose of the USB security gender and its assembly according to the present invention is,

First, even if a USB blocking block is installed in the USB port of a data storage device, it does not allow connection of only specially-made secure USB devices, but allows connection of all general standard USB devices, and once an external USB device is connected (connected) to the USB security gender of the present invention, it fundamentally blocks the connected external USB device from being separated from the USB security gender of the present invention (i.e., the problem of overcoming the existing technology that could not reconcile the free use of general USB devices and enhanced security when a USB blocking block is installed, and solving it so that they can be satisfied at the same time).

It also allows for new forms of data security by restricting the movement of data to other media in a new way.

Second, by connecting the socket and plug with a cable, it is possible to conveniently use data backup (copy) or input in difficult-to-use spaces such as the back or deep space of equipment, such as industrial equipment, for data storage devices that are difficult to use due to their location (convenience of data backup and input based on the premise of enhanced security).

Third, the simple configuration makes it easy to connect external USB devices while ensuring that they are not removed after connection.

Fourth, the present invention provides a USB security gender and its assembly, which are suitable for preventing data from leaking externally by attaching an anti-theft sensitive tape to the inside of the housing of the present invention so that when a specific area is left, an alarm sound is generated by a security device.

The USB security gender of the present invention for achieving the above purpose comprises a plug that is inserted into and connected to a USB port of a data storage device, a socket into which an external USB device is inserted and connected, and a cable connecting the socket and the plug.

The socket is characterized in that it comprises a housing made of synthetic resin material, one end of which is open and the other end to which the cable is connected, a socket frame built into the housing and having an insertion space formed in the front-back direction in which an external USB device is inserted, a terminal block provided in the socket frame so as to partition the insertion space of the socket frame upward and downward and having a plurality of socket terminals, and a separation blocking member provided in the socket frame and preventing an external USB device inserted into the socket frame from being separated in the opposite direction to the insertion direction when the external USB device is inserted into the insertion space of the socket frame such that the terminal of the external USB device is connected to the socket terminal of the socket.

The USB security gender assembly of the present invention for achieving the above purpose comprises a USB security gender including a plug that is inserted into a USB port of a data storage device and connected, a socket into which an external USB device is inserted and connected, and a cable connecting the socket and the plug; and

comprising an external USB device that connects to the socket of the above USB security gender;

The above socket comprises a housing 1 made of synthetic resin material, one side of which is open and the other side to which the cable is connected, a socket frame built into the housing and having an insertion space formed in the front-back direction for inserting an external USB device, a terminal block provided in the socket frame to partition the insertion space of the socket frame upward and downward and having a plurality of socket terminals, and a separation blocking member provided in the socket frame to prevent an external USB device inserted into the socket frame from being pulled out and separated in the opposite direction to the insertion direction when the external USB device is inserted into the insertion space of the socket frame so that the terminal of the external USB device is connected to the socket terminal of the socket.

An upper hole is formed on the upper side of the connector shell of the above external USB device,

The above separation blocking member is characterized in that it includes an upper elastic catch piece, the rear end of which is provided on the socket frame, the front end is formed to be positioned in the insertion space of the socket frame, and when an external USB device is inserted into the insertion space of the socket frame, the front end is caught and fixed in the upper hole of the external USB device, thereby preventing the external USB device from falling out and separating from the USB security gender.

The USB security gender and its assembly according to the present invention having the above configuration have the following effects.

First, it has the effect of allowing connection of all standard USB devices rather than only specially designed security USB devices, while fundamentally blocking the connected external USB device from being separated from the USB security gender of the present invention once it is connected (connected) to the USB security gender of the present invention.

In other words, when a USB blocking block is installed, the free use of general USB devices was previously impossible, but this inconvenience can be resolved while simultaneously enhancing security. Thus, the previous incompatible technologies of free use of general USB devices and enhanced security can be overcome and satisfied at the same time.

As a result, the new method has the effect of limiting the movement of data to other media and strengthening data security.

Second, by connecting the socket and plug with a cable, it is possible to conveniently use data backup (copy) or input in difficult-to-use spaces, such as the back or deep spaces of equipment, such as industrial equipment, where data storage devices are difficult to use due to their location (convenience of data backup and input, based on enhanced security).

Third, the simple configuration makes it easy to connect an external USB device, while also ensuring that it is not removed after connection.

Fourth, by attaching an anti-theft sensitive tape to the inside of the housing of the present invention, there is an effect of preventing external data leakage by causing an alarm to sound through a security device when a specific area is left.

The following is a detailed description of a preferred embodiment of the USB security gender and its assembly according to the present invention with reference to the attached drawings.

The USB security gender of the present invention is a USB security cable gender.

The USB security gender of the present invention is a USB 3.0 security gender.

The USB security gender of the present invention is a USB 3.0 security cable gender.

In this specification, USB 2.0 means a USB 2.0 device, and USB 3.0 means a USB 3.0 device, and are abbreviated for convenience.

A USB security gender (1) according to one embodiment of the present invention comprises a plug (20) that is inserted into and connected to a USB port (2a) of a data storage device (2), a socket (10) into which an external USB device (5) is inserted and connected, and a cable (30) that electrically connects the socket (10) and the plug (20) (connects the terminal of the socket and the terminal of the plug), and the socket (10) comprises a housing (110) made of synthetic resin, one side of which is open toward the external USB device (5) and the other side of which is connected to the cable (30), a socket frame (120) built into the housing (110) and having an insertion space (S) into which an external USB device (5) is inserted formed in a front-back direction, a terminal block (130) provided in the socket frame (120) so as to divide the insertion space (S) of the socket frame (120) upwardly and downwardly and having a plurality of socket terminals (131), and the socket When an external USB device (5) is inserted into an insertion space (S) of a socket frame (120) so that a terminal (drawing number not indicated) of the external USB device (5) is connected to a socket terminal (131) of a socket (10), the socket frame (120) is characterized in that it includes a separation blocking member (141, 142) to prevent the external USB device (5) inserted into the socket frame (120) from being separated in the opposite direction (reverse direction) to the direction in which it was inserted.

According to the above configuration, rather than allowing connection of only a specially-made security USB device (here, the specially-made security USB device means a USB device specially-made to be compatible with a USB blocking block (3)), connection of all general standard USB devices (5) is allowed (i.e., convenience of use of general standard USB devices is implemented), and once an external USB device (5) is connected (connected) to the USB security gender (1) according to the present invention, the connected external USB device (5) cannot be separated from the USB security gender (1) according to the present invention, thereby restricting the movement of data, thereby enhancing security (a new method of enhancing security that guarantees free use but enhances security).

Accordingly, after being connected to the USB security gender (1) of the present invention, the external USB device (5) cannot help but move as one by being connected to or separated from the data storage device (2) together with the USB security gender (1), and as a result, the security of data input and movement is enhanced.

As described above, once an external USB device (5) is inserted into the socket (10), it can never be removed, thereby maintaining security. This will be specifically explained.

First, in terms of data backup, which backs up data in a data storage device (2) to an external USB device, the external USB device (5) cannot be used alone and must be used only in conjunction with a USB security gender (1) according to the present invention, thereby preventing data backup.

Because, when a USB blocking block (3) is installed in a data storage device (2), a general external USB device (5) cannot be used alone, and the plug (20) of the USB security gender (1) according to one embodiment of the present invention is formed to be compatible with the USB blocking block (3), the external USB device (5) can only be used integrally with the USB security gender (1) according to the present invention.

In addition, in terms of data input from an external USB device (5) to a data storage device, the external USB device (5) and the USB security gender (1) of the present invention can only be used together, so that an external USB device (5) that is not permitted (undesignated) cannot be used and only a designated (permitted) external USB device can be used, thereby enhancing security in terms of data input.

In addition, by connecting the socket (10) and plug with a cable (30), it is possible to conveniently use the data backup (copy) or input in spaces where it is difficult to use, such as in the back or deep space of equipment, such as in the case of industrial equipment where data storage devices are difficult to use due to location.

In the USB security gender (1) according to one embodiment of the present invention, the separation blocking member (140) is formed so that the rear end is elastically provided up and down with respect to the insertion space (S) of the socket frame (120), and the front end is positioned in the insertion space (S) of the socket frame (120), and when the external USB device (5) is inserted into the insertion space (S) of the socket frame (120) so that the terminal (drawing number not indicated) of the external USB device (5) is connected to the socket terminal (131) of the socket (10), the front end is caught and fixed in the upper hole (53) formed in the upper part (52t) of the metal connector shell (52) surrounding the connector body (51) of the external USB device (5), thereby preventing the external USB device (5) inserted into the socket frame (120) from being separated from the USB security gender (1) by falling out in the opposite direction (reverse direction) to the insertion direction. It is characterized by comprising a catch piece (141).

In the illustrated embodiment, the upper elastic catch piece (141) is composed of two pieces.

In a USB security gender (1) according to one embodiment of the present invention, the upper elastic engaging member (141) is characterized by being formed with a downward slope from the rear end to the front end so as to elastically displace upward and downward about the rear end as an axis (strictly, elastic rotational displacement about the rear end as an axis) so as not to impede the insertion and advancement of an external USB device (5) into the insertion space (S) of the socket frame (120), while at the same time allowing the external USB device (5) to be elastically restored downward by elastic restoring force at the position of the upper hole (53) of the connector shell (52) and to be caught and fixed in the upper hole (53) of the connector shell (52) when the device is inserted into the insertion space (S) of the socket frame (120).

According to this, the connection of an external USB device (5) can be easily made through a simple configuration, while reliably preventing it from being disconnected after connection.

In a USB security gender (1) according to one embodiment of the present invention, the insertion space (S) of the socket frame is divided into an upper insertion space (Sa) and a lower insertion space (Sb) by a terminal block (130), and the tip of the upper elastic catch piece (141) is formed so that it is positioned inside the upper insertion space (Sa) of the socket frame (120), and as the external USB device (5) advances to be inserted into the insertion space (S) of the socket frame (120), the tip of the upper elastic catch piece (141) is elastically displaced upwardly by elasticity, and thereafter, by the downward restoring force of the upper elastic catch piece (141), the tip of the upper elastic catch piece (141) is maintained in contact with the upper part (52t) of the connector shell (52) of the external USB device (5) that advances into the insertion space (S), and then the connector When the tip of the upper elastic catch piece (141) is positioned in the upper hole (53) formed in the upper part (52t) of the shell (52), it elastically returns in the opposite direction to the initial elastic displacement and is caught and fixed in the upper hole (53) of the connector shell (52), thereby preventing the external USB device (5) from slipping out in the reverse direction.

In particular, the tip of the upper elastic catch piece (141) is caught on the tip edge (53f) of the upper hole (53) of the connector shell, thereby blocking reverse movement.

According to this, the connection of an external USB device (5) can be easily made through a simple configuration, while reliably preventing it from being disconnected after connection.

In a USB security gender (1) according to one embodiment of the present invention, the socket frame (120) is configured to include a plate-shaped upper portion (120t), a pair of plate-shaped side portions (120s) extending downward from the left and right sides of the upper portion (120t), and a plate-shaped lower portion (120b) extending inward from the pair of side portions (120s), at least one upper opening (121) is formed in the upper portion (120t), and the upper elastic engaging piece (141) is characterized in that it is formed integrally with the upper portion (120t) of the socket frame (120) so as to be elastically displaceable in the upper and lower directions with respect to one side (drawing number not indicated) of the upper opening (121).

In a USB security gender (1) according to one embodiment of the present invention, the upper opening (121) is formed by approximately pressing-cutting the remaining inner circumference excluding the one side into a shape of the letter “ㄷ” and then folding the inside of the press-cut cut inner circumference downward, and the upper elastic catch piece (141) is characterized by being formed by the inside of the press-cut cut inner circumference.

According to this, the upper opening (121) and the upper elastic catch piece (141) can be manufactured simultaneously, thereby reducing the product manufacturing work and improving workability.

In a USB security gender (1) according to one embodiment of the present invention, the socket frame (120) is characterized in that it is formed into a square tubular shape by bending a plate-shaped plate.

In a USB security gender (1) according to one embodiment of the present invention, the socket frame (120) is configured to further include an upper bend portion (125t) that is formed to be bent upward along one side of an upper portion (120t) of the socket frame (120), a lower bend portion (125b) that is formed to be bent downward along one side of a lower portion (120b) of the socket frame (120), and a side bend portion (125s) that is formed to be bent outward along one side of the left and right side portions (120s) of the socket frame (120), and the socket frame (120) is characterized in that, while the socket frame (120) is inserted into a cavity of an injection mold, a resin for injection molding is injected into the cavity to form a housing (110), and at the same time, the socket frame (120) and the housing (110) are integrally fastened.

At this time, the upper bending portion (125t), the lower bending portion (125b), and the side bending portion (125s) can be partially molded into the interior of the housing (110) during injection molding of the housing, thereby strengthening the fastening force.

In a USB security gender (1) according to one embodiment of the present invention, the upper elastic catch (141) is characterized by including a first curved portion (141a) formed in a curved manner in a plate-like shape, convexly upwardly at the tip and concavely downwardly, a second curved portion (141b) formed by extending from the first curved portion (141a) and concavely upwardly (convexly downwardly) and convexly downwardly again, and a third curved portion (141c) formed by extending from the second curved portion (141b) and convexly upwardly (concavely downwardly).

These morphological features can increase elasticity and improve elastic displacement and restoring force.

In the USB security gender (1) according to one embodiment of the present invention, the separation blocking member (140) is formed so that the rear end is elastically provided up and down with respect to the insertion space (S) of the socket frame (120), and the front end is positioned in the insertion space (S) of the socket frame (120), and when the external USB device (5) is inserted into the insertion space (S) of the socket frame (120) so that the terminal (drawing number not indicated) of the external USB device (5) is connected to the socket terminal (131) of the socket (10), the front end is caught and fixed in the lower hole (54) formed in the lower part (52b) of the metal connector shell (52) surrounding the connector body (51) of the external USB device (5), thereby preventing the external USB device (5) inserted into the socket frame (120) from being separated from the USB security gender (1) by falling out in the opposite direction (reverse direction) to the insertion direction. It is characterized by comprising a catch piece (142).

This will allow us to block further separation.

In the illustrated embodiment, the lower elastic catch piece (142) is composed of two pieces.

In a USB security gender (1) according to one embodiment of the present invention, the lower elastic engaging member (142) is characterized by being formed with an upward slope from the rear end to the front end so as to elastically displace up and down about the rear end as an axis (strictly, elastic rotational displacement about the rear end as an axis) so as not to impede the insertion and advancement of an external USB device (5) into the insertion space (S) of the socket frame (120), while at the same time allowing the external USB device (5) to be elastically restored downward by elastic restoring force at the position of the lower hole (54) of the connector shell (52) and be caught and fixed in the lower hole (54) of the connector shell (52) when the device is inserted into the insertion space (S) of the socket frame (120).

And, the insertion space (S) of the socket frame is divided into an upper insertion space (Sa) and a lower insertion space (Sb) by a terminal block (130).

In a USB security gender (1) according to one embodiment of the present invention, the tip of the lower elastic catch piece (141) is formed to be positioned inside the lower insertion space (Sb) of the socket frame (120), and as the external USB device (5) advances to be inserted into the insertion space (S) of the socket frame (120), the tip of the lower elastic catch piece (141) is elastically displaced upwardly by elasticity, and then, by the upward restoring force of the lower elastic catch piece (142), the tip of the lower elastic catch piece (142) is maintained in contact with the lower part (52b) of the connector shell (52) of the external USB device (5) advancing into the insertion space (S), and then the tip of the lower elastic catch piece (142) is inserted into the lower hole (54) formed in the lower part (52b) of the connector shell (52). When positioned, it is elastically restored in the opposite direction to the initial elastic displacement and is fixed by being caught in the lower hole (54) of the connector shell (52), thereby preventing the external USB device (5) from slipping out in the reverse direction.

In particular, the tip of the lower elastic catch piece (142) is caught on the tip edge (54f) of the lower hole (54) of the connector shell, thereby blocking reverse movement.

In a USB security gender (1) according to one embodiment of the present invention, the socket frame (120) is configured to include a plate-shaped upper portion (120t), a pair of plate-shaped side portions (120s) extending downward from the left and right sides of the upper portion (120t), and a plate-shaped lower portion (120b) extending inward from the pair of side portions (120s), and at least one lower opening (122) is formed in the lower portion (120b) of the socket frame (120), and the lower elastic engaging piece (142) is characterized in that it is formed integrally with the lower portion (120b) of the socket frame (120) so as to be elastically displaceable in the upper and lower directions with respect to one side of the lower opening (122).

In a USB security gender (1) according to one embodiment of the present invention, the lower opening (122) is formed by press-cutting the remaining inner circumference, except for one side (drawing number not indicated) of the lower opening (122), into an approximate “ㄷ” shape, and then folding the inside of the press-cut cut inner circumference upward (inward), and the lower elastic catch piece (142) is characterized by being formed by the inside of the press-cut cut inner circumference.

According to this, the lower opening (122) and the lower elastic catch piece (142) can be manufactured simultaneously, thereby reducing the product manufacturing work and improving workability.

The above socket frame (120) is characterized by being formed into a square tubular shape by bending a plate-shaped plate.

In a USB security gender (1) according to one embodiment of the present invention, the lower elastic catch (142) is characterized by including a first curved portion (122a) formed in a curved manner in a plate-like shape, convexly upwardly at the tip and concavely downwardly, a second curved portion (122b) formed by extending from the first curved portion (122a) and concavely upwardly (convexly downwardly) and convexly downwardly again, and a third curved portion (123c) formed by extending from the second curved portion (122b) and convexly upwardly (concavely downwardly).

According to this, elastic displacement and restoring force can be improved, thereby ensuring operational reliability.
