Connection assemblies are disclosed herein for use with a computing device. In some examples, the connection assembly includes a collar that is rotatably disposed about a first connector and is transitionable between a first position and a second position. When the collar is in the first position, shoulders of a second connector coupled to the first connector interfere with corresponding shoulders within the collar to prevent withdrawal of the second connector from the first connector. When the collar is in the second position, the shoulders of the second connector are misaligned with the corresponding shoulders within the collar so that the second connector is freely removable from the first connector.

The present application provides an adaptor, the adaptor includes a plug, a signal extension cord and an adaptor body; the signal extension cord is in an L shape, and one end of the signal extension cord is connected to a sidewall of a tail end of the plug, the other end of the signal extension cord is connected to the adaptor body, such that the plug, the signal extension cord and the adaptor body are integrally formed a U-shaped structure, and when the adaptor is configured to be plugged into a communication interface of an electronic device, the adaptor body is configured to be located on a back side of the electronic device. The present application provides an adaptor, which has a function of curved structure, and improves the user experience when holding the electronic device.

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.

An adapter provides wireless communication and charging to a wireless mouse. The adapter includes a wireless dongle that provides wireless communication to the wireless mouse. A charging plug connected to a cable provides charging. The adapter and wireless mouse include interfaces that magnetically the adapter to the wireless mouse when in close proximity. A shroud on the adapter provides physical security when the adapter and wireless mouse are connected.

An electronic device having a detachable memory is provided with a docking connector, and includes a device body and a memory. The device body has an accommodating slot and a stopping portion provided corresponding to the accommodating slot, and the stopping portion and the accommodating slot jointly form a displacement space in between. The memory is provided with a connector and a protruding stopped portion. When the memory is accommodated in the accommodating slot, the stopped portion is moved along into the displacement space and is stopped by the stopping portion, and the connector is docked with the docking connector. Thus, the memory is provided with an anti-misplugging effect.

An assembled waterproof and dustproof structure for charging devices, which includes a charging device casing with a first opening, a cable cover assembly including a base provided with an USB connection interface and an accommodating space, a bracket structure with a second opening, and a cover covering the USB connection interface to form a waterproof and dustproof protective cover. The first opening, the USB connection interface and the second opening are aligned with each other. The cable cover assembly, the charging device casing and the bracket structure utilize a set of snap-type components respectively disposed on the cable cover assembly and the bracket structure to form a waterproof and dust-proof snap-fit structure that closely fits in sequence from outside to inside.

An assembly includes an electrical cord, an electrical connector, and a housing having a first end engaged with the electrical cord and a second end from which the electrical connector extends. The first end has a first transverse cross-section and the second end has a second transverse cross-section different from the first transverse cross-section.

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.

The disclosure provides an electrical connector, including a shell, an insulating body, a plurality of terminals, and a grounding piece. Another electrical connector is inserted into a insertion space of the shell along a insertion axis. The insulating body and the grounding piece are arranged on the shell. The terminals are arranged on the insulating body along an alignment axis. The grounding piece includes a fixed portion, two first connecting portions which extend from the fixed portion, two second connecting portions which extend from the fixed portion, two clamp arms respectively extending from the two first connecting portions, and two grounding legs respectively extending from the second connecting portions. The first connecting portions and the second connecting portions extend at opposite directions. The clamp arm and the grounding piece extend at opposite directions.

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.
