A cable locking device includes a first part and a second part. The first part includes a first cavity for receiving a first electrical wire and a second cavity. The second part includes a first cavity for receiving a second electrical wire and a projection. The projection is configured to be inserted into the second cavity of the first part. A first channel is formed within the second cavity of the first part and extends from an opening of the second cavity. A second channel is formed within the second cavity of the first part and is connected to the first channel and extends in a transverse direction of the first channel. A pin is formed on the projection of the second part and is configured to fit within the first channel and the second channel of the first part. The pin is configured to engage sidewalls of the second channel so as to frictionally hold into place the pin with respect to the second channel to connect the first part to the second part.

The invention relates to a device for connecting feed lines, comprising: first electrical connector elements which can each be connected to a power supply, and first fluid connection elements which can be connected to a working fluid source, all of said elements being grouped together in a fixed manner in a first stationary connector; a power feed line, a working fluid feed line; and a second fluid connection element coupled to a first end of a flexible tube and second electrical connector elements, grouped together in a fixed manner in a first movable connector. According to the invention, at least first end segments of the second electrical connector elements and of the flexible tube are disposed inside an elastically flexible hose that is connected to the first movable connector.

A jumper cable which includes a receptacle mounted on, near or within a battery casing. The receptacle may include a socket having a pair of circular contacts on the inner circumference thereof electrically connected to battery terminals. The device may also include a cable having a plug on each end configured to mate with the receptacle socket. Such a plug may include a larger-diameter ring for engaging the upper contact and a smaller-diameter ring for engaging the lower contact when the plug is inserted into the socket, Accordingly, if a battery needs recharging, a plug is inserted into the receptacle associated with the dead battery and the opposing plug is inserted into a receptacle associated with a charged battery to establish electrical interconnection there between. Alternatively, an adapter having a socket and electrical clamps for grasping battery terminals may be used when a receptacle is not connected to one of the batteries.

A connector mating system that can enable the coupling and decoupling of electrical or optical power and communications channels, while in a harsh or submerged environment during which time the contacting interfaces of the power and communication channels remain fully protected from the destructive effects of the said environment. The system features a hybrid optic and/or electric connector that provides a means for electrical, optical and hybrid inter connection within an extremely hostile environment across a broad market range of applications with a novel end-seal concept in a scalable form factor with minimal actuation stresses and designed for high volume commodity manufacturing.

A first connector (R) element (100) comprises a first body (102) secured to a locking pin (104) and a first indexing member (106). The second connector (R) element (200) comprises a locking ring (216) axially immobilized and rotatable around a second body (202), as well as at least one second indexing member. The second connector element (200) comprises an obstacle (230) moving, relative to the locking ring (216), between a first position blocking the rotation of the locking ring (216), and a second, released position. The second connector element (200) comprises a blocking ring (240) moving, relative to the second body (202), between a forward position, and at least one withdrawn position. The blocking member (230) can block the locking ring (216) in a configuration where the mouth of the slot is aligned with the locking pin. During the fitting, the blocking ring (240) is pushed back by a portion (1044) of the first connector element (100).

In accordance with an example embodiment, an apparatus is disclosed. The apparatus includes an adapter, a coupler, and a sleeve. The coupler is configured to be connected to the adapter. The coupler includes a lever. The sleeve is connected to the coupler. The lever is configured to deflect when the coupler is rotated relative to the sleeve.

The invention relates to nuclear power, in particular to electric heaters in the safety systems of nuclear reactors of nuclear power plants. The object of the invention is to improve the reliability of nuclear power plants. The technical result is achieved in that the busbar unit is tubular, containing a block of tubular heaters, sealed terminal box, the connection nodes of the power wires to the output tubular heaters, which are combined in groups, the node connecting the wire supply to the output tubular heaters made in the form of a heat-resistant sealed plug bayonet connector, plug which is the output tubular heaters, pins bayonet connections are made on the body of the tubular electric heater, and the grooves of the bayonet connection are made in the form of an inclined profile surface.

An electrical pin and sleeve device is disclosed. The pin and sleeve device incorporating one or more features to facilitate easier assembly. For example, the pin and sleeve device may include an interrupted thread or a multi-start thread for coupling a first or main housing portion to a second or front housing portion of the device. In this manner, the outer housing can be assembled together with minimal number of turns to facilitate easier and faster assembly. Additionally, and/or alternatively, the front housing portion and the main housing portion may include a key such as, for example, a releasable lock (e.g., a spring plunger assembly) for indexing/indicating the proper rotational position of the front housing relative to the main housing to limit or prevent over-rotation. Additionally, and/or alternatively, a hollow O-ring may be positioned between the first and second housing portions.
