Description

The utility model relates to electrical products, in particular to electric power connectors for cables, plug connectors, plugs and can be used for quick articulation of cable network sections, various electrical units, units and machines among themselves, and power sources in stationary and mobile ground installations.

State of the art

Known electrical connector for intra-unit installation, in which the socket of the connector is made in the form of a housing of insulating material with T-grooves in which electrical contacts are fixed, consisting of each of the two racks. One of the racks is made in the form of a bar installed in a wide part of the groove, and the other with a rectilinear middle part connecting the curved contact part with the shank. Contact racks are not mechanically connected to each other (see US Pat. RF No. 2031497, class H 01 R 13/00, publ. 03.20.1995).

The disadvantage of this connector is its low reliability.

A distribution-extension device is known comprising conductors mounted inside the housing of electrical insulating material with sockets for plugs and a conductor connected to the outlet, laid on a coil and ending with a plug. Sockets for plugs are located around the perimeter of the cylinder

on rings with flexible petals at the holes for the forks. The coil with the wire is detachably connected to the current supply rods in the housing. The coil has a central inner cavity for placing the plug in the inoperative position. The lower supporting surface of the housing and coil is provided with radial grooves. The grooves of the rings interact with the protrusions of the housing and the cover (see US Pat. RF No. 2034379, class 01 R 13/00, publ. 04/30/1995).

The disadvantage of this device is the design complexity and inconvenience in operation.

The closest in technical essence and the achieved positive effect and accepted by the authors for the prototype is a power connector containing a plug with a socket with a bayonet locking device, while the plug consists of a cover with a seal connected by a chain to the housing through the shank, insulators and pins are installed inside the housing, and the socket consists of a cover with a locking mechanism with a seal connected by a chain to a housing with contacts and a seal through a shank, an insulator (see the INTERELECTROKOMPLEKT catalog, Moscow, Russia tions, 1995).

The disadvantages of this connector are the low degree of protection IP 54 and a small range of currents up to 63 A, the ability to use connectors in AC networks with a frequency of up to 50 Hz.

Disclosure of a utility model.

The technical result that can be achieved using the proposed utility model is to reduce the overall dimensions of the connector, the compact arrangement of the pins and sockets, the exclusion of spontaneous dismemberment of the plug with a socket, the possibility of operating the connectors in AC networks with a frequency of up to 400 Hz.

The technical result is achieved using an electric power connector for panels containing a plug with a socket with a bayonet locking device, the plug consists of a cover with a seal connected by a chain to the housing, the housing is equipped with contacts and a locking mechanism, insulators with contacts are installed inside the housing, and the socket consists of a cover with a locking mechanism and a seal connected by a chain to the body with contacts, an insulator, while the plug body is made in the form of a fully-pressed plastic part, mounted on a square flange, which is equipped with holes for fastening, and on the front of the housing there is a connecting nut with a locking mechanism and ribs on the housing of the plug, and the locking mechanism of the outlet is equipped with a locking head and mounted on the neck of the lid, while on the outlet housing with a seal made grooves, and in the insulator - contact jacks, and the socket is made with the possibility of unification with a plug.
