Abstract: A connection cable locking device is configured to selectively hold an elastic hook provided on a connection head of a connection cable, thereby preventing an arbitrary operation of the elastic hook and also preventing the connection head coupled to the connection port from being separated. The connection cable locking device includes a device body provided with a holding operation space and a locking operation space in communication with the holding operation space, a holding member having elasticity and pivotably coupled to the holding operation space so as to hold the elastic hook provided on the connection head of the connection cable, and a locking member slidably coupled to the locking operation space so as to press the holding member.

Abstract: An unlocking key for a port lock of an electronic device for unlocking and separating, from a port of the electronic device, a blocking module which is inserted and coupled to the port of the electronic device and has a key recess in which a pattern part and a latch key holding recess are formed on different inner surfaces of the key recess, includes a main body casing, a movable housing installed to protrude from a front end of the main body casing, a pattern key which is fixedly installed to protrude from a front end of the movable housing, a latch key which protrudes from the front end of the movable housing, and a manipulation part which is movably installed in the main body casing and controls reciprocating of the movable housing and opening and closing of the latch key.

Abstract: A port blocking module of an electronic device and a port locking apparatus having the same includes a module frame which is formed to correspond to size and shape of a port of an electronic device, a locking module having a locking module body fixedly installed inside the module frame, a first locking member connected to the locking module body to be elastically transformable such that the first locking member selectively comes into contact with a terminal part inside the port, and a second locking member connected to the locking module body to be elastically transformable such that the second locking member is disposed by being spaced apart from the first locking member, and a pattern module which is installed to be movable between a locking position and an unlocking position inside and outside the module frame.

Abstract: An apparatus for locking a portable computer includes an apparatus body, a first clamping member rotatably coupled to the apparatus body, configured to support a first side of a computer body of the portable computer, and configured to be fitted over a first edge of a display of the portable computer, a slider coupled to the apparatus body to be reciprocally movable, a second clamping member rotatably coupled to the slider while being spaced apart from the first clamping member, configured to support a second side of the computer body of the portable computer, and configured to be fitted over a second edge of the display of the portable computer, and a locking and unlocking unit installed on the apparatus body and configured to selectively restrict or allow movement of the slider.

Abstract: The present invention relates to a locking apparatus for a LAN cable. The locking apparatus for the LAN cable includes: a connector receiving member coupled to receive a LAN port connector having a connector body, an elastic hook provided in an upper part of the connector body, and a stopping step provided in a lower part of the connector body; a locking apparatus body coupled to the connector receiving member; and a locking member disturbing operation of the elastic hook of the LAN port connector in the locking apparatus body, and movably installed to reciprocate between a locking position in which disconnecting operation of the connector receiving member and the LAN port connector is disturbed, and a unlocking position in which release operation of the elastic hook is enabled and the disconnecting operation of the connector receiving member is enabled.

Abstract: Disclosed is a network port cover module and a network port locking device having the cover module. The network port cover module includes a plurality of modules inserted into and coupled to a network port of a network device, the plurality of modules being configured to be locked and coupled together or separated from each other, and configured to be locked and coupled to or unlocked and separated from the network port according to a locked and coupled state or an unlocked and separated state of the plurality of modules.

Abstract: Disclosed is an apparatus for locking a USB port. The apparatus is configured to be coupled with the USB port including a connection part with recessed grooves, and includes: a main body including first and second mounting portions; a port coupling part coupled with the second mounting portion, and inserted into and coupled with the USB port; a locking part movably provided in the port coupling part and being movable between a lock position where the locking part is coupled with the recessed grooves and a release position where the locking part is separated from the recessed grooves; and a locking and releasing part provided in the first mounting portion to be movable reciprocally, the locking and releasing part controlling locking and releasing motions of the locking part relative to the recessed grooves by interfering with the locking part when the locking and releasing part moves.
