Electric connector

FIELD: electricity.

SUBSTANCE: electric connector consists of a plug receptacle (1) with male contacts positioned (31) within its cavity and movable plug head (2) with female contacts (32) for electric conductors ends connection (25, 26). For fixation of the plug head in the plug receptacle with form closure a shape lock ring is applied that is fitted, with part of its cross section, into the plug head groove passing along the perimeter; during the electric connector locking the ring engages, with the rest of its cross section, into the groove arranged on the inner side surface of the plug receptacle. The shape of the lock ring and the grooves as well as the lock ring material are such that the plug head (2) is taken out of the plug receptacle (1) only by a pull force in excess of a certain threshold value. The plug head (2), connected in the same way, is fixed with its end in the congruent end of the plug movable body (3) with form closure ensured by the fixture ring (4). The force enabling the plug head taking out of the plug receptacle is less than the force retaining the plug head in the plug body with fixture ring connection.

EFFECT: detachable plug performing its function without damage to the plug.

Variant implementation of the invention according to paragraph 3, the formula is suitable for any electrical connectors, characterized in restrictive part of paragraph 1 of the formula, but especially for electrical connectors made in accordance with paragraphs 1 or 2 of the formula, because this option provides a simple, reliable and compact connector with multiple electrical connectors for one electronic device.

Variant implementation of the invention according to paragraph 4, of the formula has the advantage that the movable part of the second connector, plug head, simply, safely and securely inserted into the stationary part of the second connector.

Brief description of drawings

The following is a description of embodiments of the invention illustrated in the drawings, showing:

figure 1 - single electrical connector,

figure 2 - double electric socket.

The implementation of the invention

Outlet 1 electrical connector still installed in the casing of electrical apparatus (in the General case: the body of the machine). It is located in the cylindrical cavity pin contact part 31, which is oriented parallel to the axis of the receptacle, pass through the bottom outlet and protrude into the cavity of the receptacle. To the ends of the pin contact detail is her protruding from the bottom of the outlet opposite the bottom side, soldered the ends of the conductors 25, 26.

Movable plug head 2 in its contour corresponds to the cavity of the receptacle. She has a female contact part 32, which is oriented parallel to the axis of its cylindrical shape, are arranged in the same geometric pattern, and pin the contact details in the receptacle and with the introduction of the plug head into a wall socket are in connection with them. Since pin contact details and socket contact details are distributed asymmetrically in the cavity of the socket parallel to the pin contact detail is the guide pin 6 and the plug head has a guide hole 7 is made in the corresponding geometric position. Socket contact details of their free ends, with back entrance holes hand, are connected by soldering to the ends of electrical conductors 25, 26. Electrical conductors 25, 26 are omitted in the body of the plug by the inverse of the plug head. Plug the head part of its length, which in the articulated condition is thrown over the edge of the receptacle, mounted in congruent her body cavity of the plug.

This mount provides a positive locking. With this purpose, the applied profile ring, a preference for the equipment of the ring, called the fastening ring 4 and which part of your profile is planted in a groove along the perimeter (circumference) located in the body cavity of the plug end of the plug head on the outer side surface of this end. The rest of his profile cross-section of the fixing ring 4 is given in the groove, passing through the inner side surface of the housing of the plug, and the plane of the cross section of the plug head, which made this groove, determines the depth of the installation plug the head into the body of the plug.

For fixing the plug head, plugged into a wall socket, flush those parts of the electrical connector has another profile ring, preferably a ring, called the retaining ring 5. This ring is planted as part of their cross section in the groove of the plug head, passing along its perimeter, and the introduction of plug head into a wall socket retaining ring 5 drops the rest of its cross section in the groove on the inner side surface of the plug sockets.

This connection stoparea ring includes grooves and the retaining ring 5, completed forms and material so that the movable plug head 2 can be who was about to be removed from fixed in the frame of the machine receptacle 1 only with tug, exceeding a limit value. In particular, this is to prevent unintentional extraction of the plug head from the receptacle or its loss from the receptacle without influence from the man.

On the other hand, the fastening of the plug head 2 in the housing 3 with the plug provided with fixing ring 4, is still "the same", i.e. the connection between the body of the plug and socket head on the mounting ring includes grooves and the ring 4 made in the form and material of the ring and form grooves thus, compared with the connection stoparea ring includes grooves and the ring 5, to tug, allowing you to remove the plug head of the plug sockets were less effort, which plug the head is held in the housing of the plug connection on the mounting ring. Thus exclude a situation when you try to remove the plug head from the receptacle housing plug accidentally come with plug head with possible separation of the ends of wire from the ends of the socket contact details.
