FIELD: electricity. ^ SUBSTANCE: elastic terminal contains spring terminal and electric insulator. Electric insulator is made using method of moulding together with spring terminal as a whole part, it contains support surface for contact with upper side of rail base, support surface for contact with lateral side of rail base and support surface for contact with anchor of rail fastening made at angle =0-10 to vertical surface passing through axis of spring terminal rod. Support surface for support on anchor of rail fastening contains V-shaped backfall made in horizontal plane at an angle 0 < ëñ 30 to axis of spring terminal rod with possibility of railway gauge setup. ^ EFFECT: reducing labour intensity of manufacture and erection works, improving reliability of rail fastening and its service life. ^ 2 cl, 2 dwg |
