According to the present invention, the USB connector or the port locking device of the authorized USB device can be attached to all the ports of the USB hub so as not to fall out. Therefore, it is possible to remove a USB device attached to a USB hub and connect any USB device instead, thereby preventing illegal access or information leakage.
Description
The present invention relates to a USB hub, and more particularly, to a USB hub having a function of locking a USB connector mounted on a port.
Recently, as illegal information leakage through the USB port of a computer has become a social problem, the demand for a lock device to physically close the USB port is greatly increased.
There are many different types of USB port locks. As an example, there is a type that is permanently mounted on a USB port and a type that can be removed by using a dedicated key after mounting. As another example, when the fixed type is used, there is a type in which the USB port is inserted into the USB port, a type in which the USB port is hooked to the housing hole, and a type in which the USB port is fixed by spiking . As another example, there is a type in which data communication through a corresponding USB port is not possible and a dedicated port capable of mounting a gender, so that a user can connect to the USB port by connecting a USB device to the gender.
Meanwhile, a computer user may use a USB hub to connect a plurality of USB devices to one USB port. In this case, for complete security, the USB port must be attached to each USB port on the USB hub as well as the USB port of the computer.
However, if you have to use a port lock and gender for every port on your USB hub as well as your computer's USB port, it is not only costly, but also inconvenient to manage.
The present invention provides a new type of USB hub capable of preventing unauthorized access or information leakage through a USB hub without attaching a conventional port locking device to each port of the USB hub. .
In order to achieve this object, one aspect of the present invention relates to A housing having a port through which a USB connector can be inserted; A USB terminal installed at an inner side of the port and located at an upper portion of the substrate; A connector fixing member having a fixing portion fixed to the substrate and located at a lower portion of the substrate, an elastic portion extending downward from the one end of the fixing portion at an oblique angle, and a spike protruding upward from the elastic portion, ; A pressing member located under the connector fixing member; And a locking member coupled to the pressing member to selectively restrict movement of the pressing member, wherein when the pressing member pushes up the elastic portion of the connector fixing member, the spike is inserted into the connector housing of the USB connector inserted into the port And is inserted into the formed housing hole.
In the secure USB hub according to one aspect of the present invention, the pressing member may include a rotation shaft disposed in the width direction of the elastic portion, and a contact portion selectively contacting the bottom surface of the elastic portion while rotating around the rotation shaft. At this time, the contact portion may be a cam formed on the rotation shaft, or may be a contact protrusion formed on a connection portion connected to the rotation shaft.
In addition, in the secure USB hub according to an aspect of the present invention, the pressing member is installed to be able to move up and down from the lower portion of the connector fixing member, and can push up the elastic portion when it is raised.
In addition, in the secure USB hub according to one aspect of the present invention, the pressing member is installed to be movable in the horizontal direction from a lower portion of the connector fixing member, and can push up the elastic portion when the elastic member is lowered.
In a secure USB hub according to an aspect of the present invention, the spike includes a pair of spaced-apart resilient portions, the pair of spikes being inserted into a pair of housing holes formed in the connector housing .
In addition, in a secure USB hub according to an aspect of the present invention, the locking member may include a lock formed on the pressing member or the housing to fix the pressing member to the housing.
Further, in the secure USB hub according to an aspect of the present invention, the pressing member includes a receiving portion having an inner space opened to one side, the locking member includes a pressing member engaging portion inserted into the receiving portion, And a stopper for blocking the member from moving rearward. In this case, the stopper is formed to extend downward from the fixed portion of the connector fixing member at an oblique angle, and the locking member is a portion into which the lower end of the stopper is inserted, A stopper engaging portion formed at the rear of the guide groove, and a second engaging jaw formed at the rear of the guide groove. In this case, the locking member may include a keyhole opened to the rear end, and a tip wall of the keyhole may be used as the second locking protrusion. The locking member may include: a base formed at a rear end of the pressing member engaging portion and the stopper engaging portion; A key groove formed on an upper surface of the base; A cover coupled to the base to cover the keyway; A plurality of pattern protrusions formed on the bottom of the key groove; And an engaging groove formed on a facing inner wall of the key groove.
In addition, in the security USB hub according to an aspect of the present invention, the both ends of the locking member are formed with the separation preventing protrusions whose distal ends are coupled to the side walls of the lock member and whose rear ends are spaced apart from the side walls of the lock member, The protrusion protrudes further toward the rear end, and when the protrusion protrudes through the hole formed in the housing, the protrusion protrudes from the protrusion when the protrusion protrudes into the protrusion, And the rear end is caught by the inner wall of the housing to prevent the escape.
In the secure USB hub according to one aspect of the present invention, a tensioner for supporting a USB connector is installed on both sides of the USB terminal block, and the tensioner includes a fixing part fixed to the substrate or the housing, A supporting portion having an inclined surface for supporting the connector housing of the USB connector and guiding the entry of the USB connector, and an elastic connecting portion for connecting the fixing portion and the supporting portion.
In addition, in the secure USB hub according to one aspect of the present invention, the USB terminal block includes a USB standard terminal block and a USB terminal, and the substrate is electrically connected to the USB terminal of the USB terminal block, A coupling part can be mounted.
According to the present invention, the USB connector or the port locking device of the authorized USB device can be attached to all the ports of the USB hub so as not to fall out. Therefore, it is possible to remove a USB device attached to a USB hub and connect any USB device instead, thereby preventing illegal access or information leakage.
