[0003] The disadvantage of this device is the application of significant external force during direct mating of contacts, as well as poor contact due to the possibility of contamination of the contact surface during direct mating of one surface with another.
[0004] The technical objective of the claimed solution is to eliminate additional mechanical forces when mating the conductive contacts of the plug and socket due to gravitational elements, while increasing the contact area.
[0005] The technical result of the claimed solution is the elimination of additional mechanical forces when mating the conductive contacts of the plug and socket due to gravitational elements, as well as the elimination of spark discharges due to an increase in the contact area.
[0006] The said technical result is achieved by the fact that a system of a conical socket and plug connector with gravitational contact retention is proposed, comprising a socket housing, contact current-carrying elements of the socket, fastenings of the power supply wires of the socket to the current-carrying contact elements of the socket; a plug housing and contact current-carrying elements of the plug, fastenings of the power supply wires of the plug to the contact current-carrying elements of the plug, a recess is made in the socket housing in which the contact current-carrying elements of the socket are placed, the contact surfaces of which form parts of the surface of the cone of the socket, contact current-carrying elements of the plug are placed outside the plug housing, the contact surfaces of which form parts of the surface of the cone of the plug, all opening angles of the cone of the socket coincide with all the corresponding opening angles of the cone of the plug, the dimensions of the intermediate dielectric surfaces between the contact current-carrying surfaces of the socket are such thatthat during the process of combining the contact current-carrying elements of the plug until full contact with the contact current-carrying elements of the socket, there is no overlap of the intermediate dielectric surfaces by any of the contact current-carrying elements of the plug in any direction, the socket housing and the plug housing are made with gravitational elements that ensure maintaining the contact of the current-carrying elements of the plug with the current-carrying elements of the socket, the socket housing contains a fastening for the stationary orientation of the socket relative to the direction of action of gravitational forces, the plug is made with a mass such that the gravitational force of the plug is greater than the weight of the power cord and the frictional force generated when the plug moves along the socket, characterized in that the socket housing and the contact current-carrying elements of the socket contain an additional recess for moving the power cord of the plug to the center of the inner surface of the socket and its contact current-carrying elements,wherein the power supply wires of the plug are secured at the apex of the surface of the truncated cone of the plug body and its contact conductive elements, the base of the surface of the truncated cone of the plug is covered with a dielectric material, that the strips of the contact conductive elements of the socket and the plug are arranged so that the planes passing through their central lines are perpendicular to the central axis of the truncated cone, and the minimum distance between N contact conductive elements of the socket is greater than the maximum width of the strip of any of the N-1 contact conductive elements of the plug.

[0008] Fig. 2 shows a top view of a conical plug, showing the width of the strips of the contact conductive elements corresponding to N phases: d1, d N -1 ,d N , as well as the width of the intermediate dielectric regions (bands) between the contact elements: D1, D N -1 ,D N , section A-A is shown.
[0009] Fig. 3 shows the section A-A of the socket and plug when the plug is shifted into the contact holding area, showing the dielectric housing of the socket -1, the contact conductive elements of the socket -2, with fasteners -3 of the power wires of the socket -4, the dielectric housing of the plug -5 with the contact conductive elements of the plug -6 with fasteners -7 of the power wires of the plug -8, the cable with power wires -9, the socket is connected to three phases: φ 1, φ N -1 ,φ N . The opening angle of the socket is -α розетки along this section coincides with the fork opening angle -α вилки .
[0010] Fig. 4 shows a side view of a conical plug -5 with contact current-carrying elements of the plug -6, a cable with power wires -9, and the width of the strips of the contact current-carrying elements of the plug corresponding to N phases is shown: d1, d N -1 ,d N , as well as the width of the intermediate dielectric regions (bands) between the contact elements: D1, D N -1 ,D N .
[0011] Fig. 5 shows a general view of a conical socket-1 and plug-5, with contact conductive elements of the socket-2 and plug-6, a cable with power wires-9, placed normally relative to the action of gravitational forces with the help of a fastening-10 for stationary orientation of the socket.
[0012] Fig. 6 shows the section A-A of the socket and plug when the plug is shifted into the contact retention area, in the case where the socket body -1 and the contact conductive elements of the socket -2 contain an additional recess -11 for moving the cable with the power wires -9 of the plug into the center of the inner surface of the socket and its contact conductive elements, while the power wires of the plug are fixed at the top of the truncated wedge of the surface of the plug body -5 and its contact conductive elements -6, the socket is connected to three phases: φ 1, φ N -1 ,φ N .
[0013] Fig. 7 shows a general view of a conical socket in the case where the socket body -1 and the contact current-carrying elements of the socket -2 contain a recess -11 for moving the cable with the power wires -9 of the plug to the center of the inner surface of the socket and its contact current-carrying elements, while the power wires of the plug are fixed at the top of the truncated cone of the surface of the plug body -5 and its contact current-carrying elements -6, while the socket is placed normally relative to the action of gravitational forces with the help of a fastening -10 for the stationary orientation of the socket.
[0014] The device operates as follows: a plug is inserted into the contact zone of the socket, so that the contact current-carrying elements of the plug are displaced relative to the contact current-carrying elements of the socket until complete contact is achieved, which is ensured by the coincidence of the geometric opening angles of the plug and socket, as well as other parameters, for example, the coincidence of the centers of the stripes of the current-carrying elements of the plug and socket of the corresponding N-phases.
[0015] The technical result is achieved because the tangential movement of one conductive conical surface along another allows contact to be made without additional mechanical force, eliminating foreign particles that could interfere with contact. A sufficiently large contact area eliminates spark discharges both during the contact process and during full contact; in this case, there are virtually no significant electric field gradients that could cause breakdown and spark discharges. Furthermore,To prevent short circuits during the displacement of the plug's conductive contact elements relative to the socket's conductive contact elements until full contact is made, the dimensions of the intermediate dielectric surfaces between the socket's conductive contact surfaces must be larger than the plug's conductive contact elements so that, during the alignment of the plug's conductive contact elements until full contact is made with the socket's conductive contact elements, no overlap of the intermediate dielectric surfaces occurs between the plug's conductive contact elements in any direction. In the particular case where the intermediate dielectric surfaces are parallel strips of width D1,D. N -1 ,D N , and the width of the strips of the contact conductive elements of the plug corresponding to N phases: d1,d N -1 ,d N - minimum width of strips D1, D N -1 ,DN must be greater than the maximum width of the stripes d1,d N -1 . It should be noted that the width of the socket's conductive strips:d 1розетки ,d N -1розетки ,d N розетки may be smaller or larger than the width of the conductive strips of the plug:d 1вилки ,d N -1вилки ,d N вилки , in this case the main thing is that the minimum width of the dielectric strips of the socket is D 1розетки ,D N -1розетки ,D N розетки was greater than the maximum width of the conductive strips of the plug -d 1вилки ,d N -1вилки . The width of the last strip is not taken into account, since the last conductive element of the plug (d N вилки ) cannot cross the intermediate strip of the socket, it is aligned with the last conductive element of the socket (d N розетки ).
[0016] Thus, the technical problem of the claimed solution is solved: the elimination of additional mechanical forces when mating the conductive contacts of the plug and socket due to magnetic elements, as well as the elimination of spark discharges due to the increase in the contact area.
