Abstract

The invention relates to electrical engineering. The purpose of the invention is to improve the manufacturability, reduce the cost of construction, making it safer. This goal is achieved by inserting movable inserts of cylindrical thermosetting plastic with a central hole, the outer surface of which interacts with a locking spring-loaded damper, into the longitudinal holes of the cover of the socket part of thermoplastic plastic. 3 il.

The invention relates to electrical engineering, namely to electrical connectors with devices that prevent access to life-threatening contacts.

The purpose of the invention is to improve the manufacturability, reduce the cost of construction, as well as increase safety.

FIG. 1 shows a rosette part of the electrical connection, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2

In the cover 1 of the socket part, thermoplastic plastic has longitudinal holes 2 and protrusions 3 and 4, which form the grooves in which:. The pins 5 are fitted with movable vg-tows of thermosetting plastic of cylindrical shape 6 with a through hole 7, on the outer surface of which a flat collar 8 is made. The cylindrical protrusion 11 is the axis of rotation of the to flap,

The safe electrical connection works as follows.

When the plug pins are inserted into the openings 7 of the movable inserts, the latter, with the outer cylindrical surface 9, act on the gate valve 10, retracting it to the extreme position along the protrusions 4, with the slide guides, until the plug pin is aligned with the holes in the plate located opposite sockets, and contact pins are inserted into the contact sockets. With the introduction of one contact pin into the hole 7, the latter, acting on the shoulder of the flap 10 through the outer cylindrical surface 9 of the movable insert, turns e around the axis 11, and the flap 10, the entrance by its locking lug 12

the projection surface 13 is locked. at the same time, the jacks of the Ostagotes are closed. Thus, the functioning of the device of protection of the contact sockets occurs only when exposed to two pins of the plug. Since the contact pins in the openings 7 of the movable thermosetting plastic insert are completely insulated, the cover 1 and the gate valve 10 can be made from thermoplastic plastic, which makes it possible to use cheaper injection molding plastics and increase productivity. In addition, the material capacity of the products is reduced. The above allows to reduce the cost of construction and due to the exclusion of the possibility of bias of the pin of the plug to increase electrical safety ..
