An electrical connector according to any one of claims 1 or 2, characterized in that the guides (19) extend radially relative to the hole (13). 4. An electrical connector according to any one of claims 1 or 2, characterized in that the guides (19) are parallel, with two guides (19) located in each quadrant of the cable holder (5). 5. An electrical connector according to any one of claims 1 to 4, characterized in that the rear side (15) of the cable holder (5) is made on one side with an inclined surface (18). 6. An electrical connector according to any one of claims 1 to 5, characterized in that between the cable holder (5) and the printed circuit board (3) there is a clamp (4) for securing the printed circuit board (3) in the connector housing (2). 7. An electrical connector according to any one of claims 1 to 6, characterized in that the guides (19) of the cable holder (5) are located at different levels relative to each other. 8. Electrical connector according to any one of claims 1 to 7, characterized in that over the cable holder (5) is located unloading from tension forces. 9. An electrical connector according to claim 8, characterized in that the unloading of the tension forces is made of several parts, while the first part (21) is made with two pads (26) made with the possibility of joint bending, which is adjustable limited by a spring (30), which covers the pads (26), and the third part is made in the form of a locking element (31) with the possibility of adjustable snap on the first part and / or spring (30), while the attached cable (36) is made with the possibility of centering with a given power circuit. 10. An electrical connector according to claim 8, characterized in that the first and third part of the unloading of the tension forces are made in the form of parts of metallized plastic, which are made with the possibility of connection with the ground plate (6) of the connector body (2). 11. Electrical connector according to any one of claims 1 to 10, characterized in that the electrical connector (1) is made in the form of an RJ-45 plug socket. 12. The cable holder for the electrical connector, containing a hole (13) extending from the rear side (15) to the front side (16), and is made on the front side (16) with guides (19) for cores, made with the possibility of contact with the cutting clamping contacts (8), while the guides (19) in the area of the cutting clamping contacts (8) are made with recessed sockets (20) for the cutting clamping contacts (8), and the hole (13) is made with four channels (37, 38, 39 , 40) or segments. 13. The cable holder according to claim 12, characterized in that in the hole (13) in the cable holder (5) there is a guide cross (17). 14. The cable holder according to any one of p. 12 or 13, characterized in that the cable holder (5) is made with a cylindrical protrusion (14) in the area of the hole (13) on the rear side (15). 15.
