A plug connector part for connecting to an associated mating plug connector part includes a housing. A plug-in portion is arranged on the housing and can be plugged into the associated mating plug connector part in a plugging direction to engage with the mating plug connector part when in a connection position. At least one electrical contact element is arranged on the plug-in portion. The at least one electrical contact element is for making electrical contact with the mating plug connector part. A locking element is movably arranged on the housing. The locking element has a locking position for locking the plug connector part with respect to the mating plug connector part when in the connected position. The locking element can be moved out of the locking position to unlock the connection between the plug connector part and the mating plug connector part.

A USB lock for an electronic device may comprise an inner casing, an outer casing, a USB connector and a driving unit. The inner casing has a front opening to secure the USB connector thereon. A rear portion of the inner casing has a tube body, and a first through hole penetrating through the tube body is communicated with the front opening and configured to receive the driving unit with a lock rod and a key lock. The USB lock of the present invention is configured to engage with a USB port of a 3C product to achieve the anti-theft effect, which is easily to assembly, simplifies the structure, lowers manufacturing cost and prevents the 3C product from getting infected with a virus through an unsafe USB.

A protective module for a data transmission port includes a plugging element and an unlocking element. The plugging element includes an extension portion and an end portion. The extension portion is inserted into the data transmission port. The end portion obstructs an opening of the data transmission port and is made of a first magnetically attracting material. The unlocking element includes an attraction portion adapted to attract the end portion and made of a second magnetically attracting material. The end portion of the plugging element escapes from the data transmission port as a result of magnetic attraction between the end portion of the plugging element and the unlocking element as soon as the unlocking element approaches the plugging element plugged into the data transmission port. Therefore, the protective module prevents external devices from getting connected to the data transmission port and prevents dust intrusion.

Provided is a USB link lock device. The device includes a device body, a blocking member provided on the device body to block access of an external device, an external USB port part provided on the device body to be adjacent to the blocking member, a signal connection part enabling signal transmission between a terminal inside the USB port and the external USB connecting port, a locking member selectively locked to the electronic device so that the blocking member is not forcedly removed from the USB port, a stopping member provided in the device body to be retractable into the external USB port part, a lock member movably provided on the blocking member to control a locking operation of the locking member and a blocking operation of the stopping member.

An aircraft theft protection apparatus has two mating parts that encapsulate an electrical power connecter when the power connector is removed from the aircraft's power source. When the power connector is removed the electrical power to the aircraft is interrupted preventing the aircraft from starting its engines. When encapsulated a pin lock having a non duplicating key locks the two parts together preventing the power connector to be reconnected to the aircraft's power source. When the two mating parts are fitted together a unique space is provided which allows the power connector to fit therein.

A USB combination lock for an electronic device may include a lock rod, a shell body, a USB connector, a push button, and a lock piece. The USB connector can be directly inserted into the USB port of the electronic the electronic device, and the blocking portion of the USB connector can be engaged with the USB port. When the push button is in a released position, the lock piece will block a bottom portion of the hooking member of the USB connector, and the lock piece will not be pressed inwardly by the blocking portion. Thus, by shifting the numeral wheels, the connecting piece can be turned into the lock position, leading to the combination lock of present invention achieving the burglarproof effect.

Disclosed herein is a plug feature for an electronic device. More specifically, the plug feature described herein is used to plug, fill or otherwise seal an aperture associated with a SIM tray of an electronic device. The plug feature may be coupled to an ejection mechanism and may extend at least partially into an aperture defined by the SIM tray and/or an aperture defined by the housing of the electronic device.

A connector includes a locking lever that locks a fitted state with an inlet, a release button that is provided to be movable in Z-direction positive and negative directions and rotates the locking lever by moving in the Z-direction negative direction to release the locking, a release restricting portion that is provided to be movable in X-direction positive and negative directions and to be movable to an abutting position where the release restricting portion abuts against the release button, thereby restricting the movement in the Z-direction negative direction of the release button at the abutting position to restrict the release of the locking, a solenoid as a moving portion that moves the release restricting portion in the X-direction negative direction, and a coil spring that presses the release restricting portion in the X-direction positive direction.

The plug part (10) is connectable to a mating part (1), which is used as a connector of a device (50), to form a plug-in connection. The plug part (10) includes at least one non-volatile memory (13), a communication unit (15) and a microprocessor (14). A network having such plug parts (10) can be tested by means of a testing device, which is designed to generate test signals from information stored in the memory (13), which test signals can be laid on the cable wired leading out of the plug part (10) in order to generate measurement signals. The memory (13) preferably contains a list of permissible combinations of hardware and software versions, which can be compared with the current hardware and software combination of the device (50) in order to configure the device (50) and/or authorize the device (50) for normal operation.
