Description

(54) CONNECTOR FOR MULTI-WIRE WIRES

one

The invention relates to electrical engineering, mainly in cable technology, and can be used to connect electrical cables.

It is known a cable connector device, comprising a sleeve, inside which a conductor with a cable wedging cone is located, is made as a separate part interacting with its spherical surface {1.

The disadvantage of this device is a relatively large electrical resistance, since the current lead with a wedging cone. has a point contact (similarly when the cone interacting with the current lead is flat because of the orientation of the cone by the cable cores). In addition, the current lead with the sleeve is threaded, therefore, the contact is made at several points. This device is also characterized by the complexity of motivation due to the inconvenient installation of a wedging cone.

A known coupling for connecting stranded wires, comprising a housing in which a conductive rod with conical ends is installed, in contact with the connecting wires pressed against it with the help of conical sleeves and cap nuts, the conical terminal ends of the rod are made of conductive material, and the rod is installed in the housing with the possibility of relative movement and rotation in all directions 2.

The disadvantages of this device are relatively high electrical resistance, since the electrical contact of the wires occurs only with conical ends.

15 rods; complexity of installation, since for uniform distribution of the cable cores around the conical ends of the rod, it is necessary to accurately center the cable relative to the rod.

A coupling is also known, comprising a housing, a sleeve, and a wedging conical contact element, which is double-sided and tightly coupled to the housing, and the sleeve is movable relative to it by means of a set screw 3.

The disadvantages of this device are relatively large electrical resistance, since the electrical contact of the wires occurs only with coic elements ;. complexity of installation, since for cable conductor dimensioning to be distributed around the tapered elements, it is necessary to accurately center the cable relative to the O-rod, after which this position must be fixed, and the flow is bushing. Closest to the present invention is a connector device for stranded cables containing a connecting element made in the form of two facing each other cups, wall sections of each of which are made in the form of conical collets, and the bottom of each of which has a tip facing the wedge-shaped wires the protrusion, and hollow clamping elements, having interacting with the outer surface of the collets, the conical portions of the inner surface 4, However, the reliability of the work is characteristic of this device s and complexity of technology. The purpose of the invention is to increase reliability and simplify technology. This goal is achieved in that the device is provided with a tubular insulating body having openings made from its opposite sides, each pressure member interacting the outer surface with a threaded connection with the body openings, and its cavity is designed to accommodate the wire the inner surface of the collet is conical, moreover, the taper of the outer and inner surfaces of the collets are the same. Figure 1 shows a coupling for connecting stranded conductors; on .fig.2 - section aa in figure 1. The connector consists of a body 1 of clamping elements 2 with an inner conic surface 3 in the connecting element 4. The walls of the cups of the connecting element are made in the form of collets 5, the conical surface of the collet 5 with contact being in contact with the conical surface of the flexible element 2. The tapers of the collet and the clamping element are equal, therefore in any cross section of the connecting element the distance between the outer surface of the wedge and the inner surface of the collet is constant and the area of the annular cavity between them is equal to the wire cross section. The clamping elements are twisted by two or three turns, and the stranded wires 6 are inserted into them, which are pushed onto the wedge-shaped protrusions 7. Then the clamping elements are screwed in, which press the collets around the wire. Due to the fact that the cavity area between the wedge and the inner surface of the collet is equal to the cross-sectional area of the wire and precise alignment, the installation and uniform distribution of the wire cores around the wedge-shaped protuberance is simplified. The invention allows to simplify the manufacturing technology of the connector and increase the reliability of its operation. Claims of the Invention that have an interaction with the outer surface of the collets; conical sections of the inner surface, characterized in that, in order to increase reliability and simplify the technology, it is provided with a tubular isolate Each clamping element interacts with the outer surface with a threaded one (connections to the openings of the housing, and its cavity is designed to accommodate the wire, the inner surface of the collet is conical, and the taper of the outer and inner surfaces of the collets coincide Sources of information taken into account in the examination 1.
