The disadvantage of this technical solution is the relatively high complexity and relatively low reliability of the connection.

In addition, there is known a connecting die clamp for connecting wires of an overhead power transmission line [RU 2321935, C1, H02G 7/02, 04/10/2008], comprising a body made of a shaped profile with grooves for laying at least one die in them of connected wires cross-section with grooves identical in geometrical dimensions to the grooves of the housing, and a tightening device, fastening the housing and dies with line wires laid in their gutters, the profiles of the housing and dies being made equally strong throughout their cross section iju by selecting the following relations for the distances A between the vertical axes of troughs, the height H of the housing and the ram, the radius R of curvature of the outer radius r of the grooves and ends of launders A = (1,0 ÷ 1,2) ⋅ ( d _pr.maksim. + d _bolts ) so that the wire of maximum diameter from the group of mounted wires in the clamp is located without a gap with the bolts of the tightening device, where d _pr.maxim. - the maximum diameter of the wire from the group of wires mounted in the clamp, d _bolts - the diameter of the bolt of the tightening device, N = (0.3 ÷ 1.2) ⋅A, R = (0.9 ÷ 1.1) ⋅H, while the profiles of the case and dies are made in the upper part with a rectangular platform, the width B and height h of which are determined from the following relations: B = (0.8 ÷ 1.1) ⋅D descript _{. surround nuts} where D _{des. surround nuts} - the diameter of the described circle of the nut mounted on the bolt of the tightening device, h = (0.1 ÷ 0.3) ⋅ Н, respectively.

The disadvantage of this technical solution is also the relatively high complexity and relatively low reliability of the connection.

The closest in technical essence and the achieved result when using it is a die clamp [RU 13520, U1, H01R 43/00, 04/20/2000] containing a housing and at least one clamping plate with grooves of depth H ₁ facing each other to a friend, and at least on the bar on the opposite side opposite these grooves, additional grooves of depth H ₂ ≠ H _{1 are made} .

The disadvantage of this device is the relatively low reliability.

The problem, which is solved in the proposed technical solution, is aimed at improving reliability.

The required technical result is to increase reliability.

The problem is solved, and the required technical result is achieved by the fact that in the device containing two pressure plates with longitudinal grooves made along their edges, and coordinated by diameter and placement of holes in them in the central part, designed for bolting, according to the utility model plate insert with holes in its central part, coordinated in diameter and placement with holes in the pressure plates, and in the upper part of the plate insert there is an arc ny protrusion in the central part of which is formed a threaded hole for the pressing member, wherein the openings in one of the clamping plates are made with threads for bolting and clamping plates disposed between the insert plate with the arcuate protrusion in its upper part.

In addition, the desired technical result is achieved by the fact that in the pressure plates and in the central part of the plate insert, two holes are made.

In addition, the required technical result is achieved in that a clamping screw is used as a clamping element.

In addition, the desired technical result is achieved by the fact that, as a clamping element, a clamping bolt is used.

In addition, the desired technical result is achieved by the fact that the device is arranged to be placed in a plastic insulating casing having a detachable base with holes for wires.

In addition, the desired technical result is achieved by the fact that the device is arranged to be placed in a plastic insulating casing having a detachable base with holes for wires and a screw cap.
