The invention discloses a low-
noise communication cable connection positioning device, which is used for positioning a connection end of a cable to be connected with a connecting base (8) of communication equipment. The low-
noise communication cable connection positioning device comprises a
bed frame (9) and a positioning motor (7), wherein the positioning motor (7) is fixed in a lower base body (98) of the
bed frame; a screw rod (71) driven by the positioning motor (7) comprises a
tail end which is used for being fixed in an upper beam (93) of the
bed frame (9) in a rotating manner; and the screw rod (71) and a movable wedge block (72) are in threaded fit, so that the left side of the movable wedge block (72) and a guide rail groove (921) in a longitudinal bracket (92), which is arranged between the upper beam (93) and the lower base body (98), of the bed frame (9) are in sliding fit; and the wedge surface at the right side of the movable wedge block (72) is jointed with the inclined surface (63) at the left side of a clamping block (6).
