Abstract

The invention relates to electrical engineering. The aim of the invention is to increase reliability. The device contains an insulating socket 1 with a threaded hole 2. In the socket there is a screw 3 with a stepped shank 7, on which a contact element 4 in the form of a cylindrical spring is fitted with a gap. In the nest 1 at an angle to its axis, holes 5 are made for the conductors 6. The screw 3 is provided with a stop 8 in the form of an insulating cone mounted rotatably on the shank 7. When the conductors 6 interact with the contact element 4, its turns deform, ensuring contact pressure several points with simultaneous locking of the screw 3 in the threaded hole 2. 1 sludge.

screw 3 and spring contact element Q pa, providing contact pressing 4, Holes 5 for connecting conductors 6 are made in the socket at an angle to the axis of the socket. Contact element 4 is executed in the form of a twisted cylindrical spring. Screw 3 finishes- 5 with a stepped shank 7, on which the contact element 4 is fitted with a gap, and provided with a limiter 8. At the junction of the threaded surface of the screw 3 into the shank 7, the radial hole 9 is full, the end 10 of the contact spring 4 is bent and The hole 9, the Restraint 8 has the shape of a cone, is made of insulating material and is mounted rotatably about the axis of the screw 3. The taper angle of the limiter is chosen equal to or greater than the angle at which the holes 5 are made,

The device works as follows.

The ends of the wires 6 are inserted into the holes 5 so that their ends are located in the non-threaded part of socket 2, Screw 3 with the contact element 4 mounted on it are inserted into the threaded part of the hole 2 sockets 1, Cone set. when the movement of the screw 3, the delichitel 8 interacts with the ends of the DO conductors

at several points. When the screw 3 is disconnected from the socket 1, the spring contact element rests with its end face the restraint 8, which prevents its extension. The device provides reliable multipoint contact due to the presence of elastic deformation of the spring coils. This ensures the locking of the screw and the fixation of the contact element.
