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: 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 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 lock module for an electronic device includes a module frame formed by corresponding to size and shape of a port of an electronic device and having a frame shape having open opposite ends, the module frame having a main locking member configured to be transformed outward by an external force so as to be held in or released from a locking hole formed in the port, a locking module having a locking module body fixedly installed inside the module frame, and a sub-locking member connected to the locking module body such that the sub-locking member is elastically transformable, and a pattern module being installed to move inside and outside of the module frame between a locking position and an unlocking position.

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: An electronic component includes a magnetic body; and a coil pattern embedded in the magnetic body, the coil pattern including an internal coil part having a spiral shape and a lead part connected to an end of the internal coil part and exposed to an external surface of the magnetic body.
