A connector has at least one engagement ball that is movable between an engagement position and a disengagement position. A movement of an engagement ball operating part of the connector relative to an inner housing of the connector can force the at least one engagement ball from the engagement position into the disengagement position. The engagement ball operating part can have claws that extend through at least one window in a supporting part or the inner housing or between the supporting part and the inner housing. A system which includes the connector and a counter connector lockable to the connector by f a locking mechanism has the at least one engagement ball of the connector engage with an engagement part of the counter connector. If the at least one engagement ball is in the engagement position and the locking mechanism is loaded, the at least one engagement ball does not exert a force on a part of the connector that is movable relatively to the inner housing and retains the engagement ball in the engagement position. A method of unlocking a connector from a counter connector includes moving an engagement ball of the connector from an locking position, in which the engagement ball is engaged with an engagement part of the counter connector to lock the connector to the counter connector, to an unlocking position, in which the engagement ball is no longer engaged with the engagement part of the counter connector.

A connecting plug includes a locking pin arranged at a connector face. The locking pin has at least one latching element and a counter-piece. The latching element is configured for engaging with at least one counter-latching element of a second connector part. The locking pin includes a spring element configured for resiliently pressing the at least one latching element and the counter-piece against each other. The counter-piece is shaped and configured for pressing the at least one latching element in a radially outward direction and for positively locking the at least one latching element in an engaged position as soon as the at least one latching element is engaged with the at least one counter-latching element.

A plug-in assembly structure for a UAV includes a first component (1), a second component (2) and a limit assembly (3). The first component (1) includes a first plug (11) and a positioning sleeve (12), and the positioning sleeve (12) is provided with a first through hole (121). The second component (2) includes a second plug (21), the radial direction of the second plug (21) is provided with a limit hole (2111), the second plug (21) can be electrically connected to the first plug (11), and the limit hole (2111) is facing the first through hole (121). The limit assembly (3) is installed in the limit hole (2111). The limit assembly (3) includes a first elastic element (31) and a limit element (32).

A manual toothbrush, including a disposable head comprising a thermoplastic material and a reusable handle comprising an aluminum material, has a center of gravity, a longitudinal axis, and mutually opposite front and back sides. The handle has a proximal end, which is adjacent to the head when the head is attached to the handle, and a distal end opposite thereto. The center of gravity lies within the handle even when the brush head is loaded with toothpaste, wherein the center of gravity is arranged at or in close proximity to the pivot point of a wrist joint of a user brushing teeth, which arrangement facilitates precise and accurate brushing movements by the user. The handle's proximal end terminates with a chamfered surface, wherein the chamfered surface and a cross-sectional area perpendicular to the axis form therebetween an angle from about 15 to about 30 such that one of the front side and the back side of the handle is shorter than the other.

A surgical device and method of processing includes a cable and a first adapter. The adapter includes a body, an electrical contact connected to the cable, and an engagement assembly. The engagement assembly includes a latch coupling or a communication coupling. The latch coupling is movable between a locked and an unlocked position and includes a catch member. The communication coupling is configured to be resiliently biased into engagement between the electrical contact and an instrument or generator.

An electrical connector comprises a plug connector and a socket connector connectable to respective electrical conduits, wherein the plug connector and at least partly prevent or minimize rotational and/or longitudinal movement of the electrical conduits relative to the connectors. The socket connector may comprise a rotatable retainer comprising one or more flange members and the plug connector may comprise one or more complementary flange members, so that rotation of the retainer facilitates engagement between the respective flange members of the socket connector and the plug connector. Power sources are also provided which comprise the hereinbefore described rotatable retainer and flange elements.

A street light has a pole of at least 6 feet in length, and has an electrical socket attached to an end of the pole. The socket includes a body having an interior, and a cover positioned on the body to cover the interior of the body. The cover has a ring-shaped openings providing passage into the interior of the body. Resiliently mounted electrical contactors are each positioned in the interior of the body and adjacent to one of the ring-shaped openings in the cover. A central bore extends through the body, and a ledge is positioned at the end of the bore to extend radially outward. The socket is connectable to a mating plug to mechanically and electrically connect a street light or other device to the pole. The street light can include sensors that are connectable using a similar socket and plug.

An electrical train coupling having two coupling halves, each including at least one electrical contact element, which is electrically contactable with an electrical contact element of the particular other coupling half, including one electrical connection per coupling half. At least one electrical contact element of at least one coupling half is supported by a decoupling element movable against the force of a force accumulator at least also along a coupling direction of the coupling halves, the decoupling element, in a coupled state of the two coupling halves, being moved against the force of the force accumulator into an electrically conductive contact of the electrical contact element with the electrical connection of the coupling half and, in a decoupled state of the two coupling halves, moved by the force of the force accumulator with the electrical contact element, being lifted off of the electrical connection to disconnect the electrically conductive contact to the electrical connection.

An electrical conductor assembly for use in a power distribution assembly includes an electrical conductor. A casing covers at least a portion of the electrical conductor. The casing insulates the at least a portion of the electrical conductor.

Electric bicycles anchoring system of the type comprising a first module (1) intended to be installed on the base (3) of an anchoring and recharge station for electric bicycles and a second module (2), complementary to the first module (1) and intended to be installed on an electric bicycle. It allows anchoring and battery recharge of the electric bicycle and triggering an alarm when it detects attempted robbery of the bicycle. It comprises electrical charge connections, data transmission elements in the two modules which make contact with each other when the bicycle is anchored to the station base.
