A connector includes a body having gear teeth. A first sleeve is rotatably coupled to the body. A moveable member is positioned in a hole of the first sleeve. A second sleeve is movable with respect to the first sleeve between a locked and unlocked positions. A releasable locking member is positioned between the moveable member and the gear teeth. In the unlocked position of the second sleeve, a recess formed in the second sleeve is aligned with the opening. Upon rotation of the first sleeve, the moveable member is translated into the recess as the releasable locking member travels along the gear teeth. In the locked position of the second sleeve, the recess is rotationally spaced from the opening, and, the releasable locking member is sandwiched between the gear teeth and the moveable member to prevent rotation of the first sleeve with respect to the connector body.

A connector for repeatedly attaching and detaching a head to and from a handle of a manual oral care implement has an outer surface and a recess. The recess forms a cavity within the connector, wherein the cavity comprises a spring-loaded ball-snap element, the element comprising a ball and a spring, the spring applying a radial force onto the ball in a direction towards the outer surface of the connector.

Disclosed is a push-button lock for locking a plug-in connector housing. The lock has a push-button body with a cylindrical unlocking recess containing an unlocking pin. The appropriate interaction of an outer contour of the unlocking pin, an inner contour of a through-opening of the plug-in connector housing and the push-button body by at least one locking element and two springs allows the plug-in connector housing to be locked and unlocked with great ease of use, the operating concept being particularly self-explanatory.

An LED light device can be securely engaged on one of its ends with a docking port that includes electrical and coolant fluid fittings for the LED light device. The docking port can include a connection body, a plurality of fittings disposed on a common side of the connection body, a release lever and a guide rail. The plurality of fittings can include a first fitting configured to mate with the electrical fitting of the LED light device and a second fitting configured to mate with the first coolant fitting of the LED light device. The guide rail can extend forwardly from the connection body away from the common side of the connection body. The guide rail can slide in a channel defined in a sidewall of the LED light device. The release lever can be moved between a locked position and an unlocked position.

The present disclosure relates to a push-pull coaxial connector comprising: an external conductor, where the external conductor is configured to internally receive the matching external conductor of a mating connector, with concave parts or through holes on the inner surface of the side wall of the external conductor that house retainers and corresponding matching concave parts on the outer surface of the side wall of the mating external conductor, of which, there are one or more protrusions on the outer surface of the side wall of the external conductor; a sleeve surrounding the external conductor, where the sleeve is able to slide between the front position and rear position along the external conductor and is able to rotate around the circumference of the external conductor, of which, there are one or more corresponding notches to receive one or more protrusions on the rear surface of the sleeve; wherein, when the sleeve is at the front position, one or more protrusions are staggered away from one or more notches and abutted on the rear surface of the sleeve to prevent the sleeve from moving backward, and at this point, part of the retainer is in the concave part or through hole of the external conductor and part of it is in the mating concave part of the mating external conductor, thus maintaining the connection between the coaxial connector and mating connector; wherein, when the sleeve is at the rear position, one or more protrusions are received in one or more corresponding notches, and at this point, the retainer fully leaves the matching concave part of the mating external conductor, thus separating the coaxial connector and the mating connector. The push-pull coaxial connector uses a simple concave-convex structure, which locks the front and rear positions of the push-pull structure of the coaxial connector and it has a simple structure and is low-cost.

An electric vehicle fastening and charging combined system for a charging and storage station, such as those used for bicycle or scooter sharing programs, where a multi-purpose cable extends between the charging and storage station and the electric vehicle, and serves to fasten the electric vehicle to the charging and storage station to prevent removal or theft of the electric vehicle, and to conduct electricity to charge the electric vehicle, and wherein the fastening and/or detaching of the cable is controlled by a wireless signal.

A replaceable head for removeable connection with a manual toothbrush handle, the head comprising: a first end, a second end opposite to the first end, a neck having a hollow portion therein and extending between the first end and the second end, and a bristle carrier disposed adjacent to the first end. The second end comprises a second-end opening leading into the hollow portion of the neck and terminates with a second-end edge comprising a chamfered surface structured and configured to mate with a corresponding chamfered surface of the handle when the head is connected thereto. The neck's hollow portion is defined by an inner wall comprising a recess for receiving a spring-loaded ball associated with a connector of the handle.

An electrical connector comprises an insulating body, a pair of first terminal members, a pair of second terminal members, and a fastening part. The insulating body comprises a mating groove. The pair of first terminal members is disposed in the mating groove. Each of the first terminal members comprises a plurality of first elastic contacting parts. The pair of second terminal members is disposed in the mating groove. The pair of first terminal members is disposed between the pair of second terminal members. Each of the second terminal members comprises a plurality of second elastic contacting parts. The second elastic contacting part abuts against the first elastic contacting portion correspondingly. The fastening part fastens the pair of first terminal members and the pair of second terminal members.

A plug is connectable to an electrical socket which has concentric ring shaped openings housing electrical contacts. The plug has a body supporting electrically conductive concentric rings insertable into the socket to contact the electrical contacts to form electrical connections. A hollow post extends away from the plug body and has a transverse aperture therethrough. A rod with a narrowed portion is slideable within the post. A spring biases the rod towards a latched position in which the narrow portion is not adjacent to the transverse aperture. A cross-brace is connected to a portion of the rod which extends outside of the post. Pins engage the cross brace and can be pushed to move the brace, and thereby push the rod to position the narrowed portion to an unlatched position adjacent the aperture to enable removal of the plug.

A plug and socket combination together with a light source for achieving the look and effect of a recessed lighting fixture with only a standard electrical junction box and without any type of recessed lighting housing. For renovations, a plug and socket combination can be used with an existing conventional recessed lighting housing.
