Some embodiments relate generally to the field of electrical installations. In particular, some embodiments relate to an electrical socket device including at least one mechanism for locking and unlocking a corresponding electrical plug. More precisely, some embodiments relate to the electrical sockets and plugs of couplers, such as those defined by International Standard IEC 60320, for example of type C13 and type C19. These (coupler) sockets and plugs are applied or used in particular in a building that has a network, for example of LAN (Local Area Network) type, or in a data center, where several items of electrically powered equipment are installed.

An electrical connector includes a housing formed of a fixed housing and a movable housing movable relative to the fixed housing. The connector further includes a terminal. The terminal includes a connecting portion to be connected to the electrical circuit board and a contact portion to be contacted with the mating connecting member. The terminal further includes a fixed side held portion, a movable side held portion, and an elastic portion. The connecting structure further includes a regulating portion for regulating the elastic portion from elastically deforming within a specific elastic deformation range. The elastic portion is configured to have a specific elastic deformation range. When the electrical connector is connected to the mating connecting member, the spring force is smaller than a holding force between the contact portion of the terminal and the mating connecting member in a direction that the electrical connector is pulled out.

An electrical junction box includes a housing that defines an internal space. The housing has a front, which is open. A buss bar is coupled to the housing and is positioned in the internal space. A plurality of connectors is coupled to the buss bar and extends through a respective opposing side of the housing. A plurality of couplers is coupled to the buss bar. The couplers are positioned on a front face of the buss bar. The connectors are configured for insertion of wires, such that the wires are coupled to the buss bar and the buss bar is coupled to an electrical circuit. The couplers are configured for insertion of wiring that is coupled to an electrical device, such as a switch, light, fan or outlet. The wiring is coupled to the buss bar and the electrical device is coupled to the electrical circuit.

A connector assembly includes a female connector having a pair of female terminals inserted into a housing of which one side is open, and including a male connector having a male terminal inserted between the pair of female terminals to come into contact with the pair of female terminals. one end of a female terminal of the pair of female terminals is fixed to an inner surface of the housing. The other end thereof is disposed to extend by a predetermined length. A displacement of the other end occurs toward the one end due to the configuration of the male connector. A contact defect problem during coupling does not occur and reworking of the connector assembly is facilitated.

A connector (10) for connection to MOLLE webbing having a plurality of MOLLE loops (18), includes an elongate body portion and first and second arrays of tabs (12) extending from the body portion arranged in laterally opposing relationship relative to one another, tabs (12) being configured for coupling to the MOLLE loops (18) so as to attach the connector to MOLLE webbing. The body portion may be substantially planar and the first and second arrays of tabs (12) are substantially co-planar with the body portion. The body portion has a width of 2.5 to 3.8 millimetres and the tabs have a pitch either individually or in a plurality thereof of 2.5 to 3.8 millimetres. The body portion may include an internal channel for receipt of a component, such as a cable, wire or tube. The connector can be fitted to a MOLLE webbing by disposing the tabs below one or more loops of the MOLLE webbing, disposing a component between the connector and the substrate, whereby the component is held by and covered by the connector. The body portion can be bent, curved or folded and attached to at least one row and at least one column of the MOLLE webbing.

The disclosure discloses a novel power cord detachable structure for portable hair curler, including a power cord, an encapsulation is fixed to one end of the power cord, and an upper handle is fixed to the top of the encapsulation. By providing a fixing slot on the fixing sleeve and inserting the fixing sleeve into the appliance, the fixing sleeve is rotated to loose and fasten the fastener, thereby achieving the detaching effect. By providing and pushing the tail sleeve, the internal rotary lock is opened, the power cord is inserted into the product, the tail sleeve is loosened, and the fixing point inside the tail sleeve returns to the position where the lock is pushed, so that the power cord will not be detached. The tail sleeve is pushed so that the internal rotary lock is opened, and the power cord can be pulled out smoothly.

A plug connector part fix a plug connector includes a housing part; a plug portion which is arranged on the housing part for plug-in connection to another plug connector part; a latching element which is arranged in a movable manner on the housing part and has a latching portion that locks to the other plug connector part, the latching element being movable between a first, locking position for establishing locking between the plug connector part and the other plug connector part and a second, unlocking, position for unlocking the plug connector part from the other plug connector part; and a fixing device to fix the latching element in the first, locking position. The fixing device releases a fixing provided by the fixing device in the first, locking position by applying a force to the latching element that is greater than a predetermined fixing force.

A railcar power connector includes a connector body defining a central opening configured to receive a portion of a cable, and a spring member having a protrusion moveable relative to the connector body between a locked position where the protrusion is configured to be secured to a mating connector and a released position where the protrusion is configured to be released from a corresponding recess of a mating connector. The protrusion moveable from the locked position to the released position upon a predetermined axial force applied to the spring member.
