The invention discloses a mounting fixture, relates to the technical field of cable wiring, and aims to improve connection efficiency for a conductive wire. According to the adopted technical scheme, the mounting fixture is used performing connection of the conductive wire of a conducive wire connector; the mounting fixture comprises a first body and a second body, wherein a supporting region used for supporting the shell of the conducive wire connector is arranged on the first body; the second body is rotationally connected with the first body; an inserting rod matched with a fixture jack in the conducive wire connector is arranged on the second body; and the inserting rod is used for pressing a moving part downwardly through the fixture jack to enable the moving part and a fixed part to be elastically converted from an initial state into a pluggable state when the shell is placed on the supporting region of the first body of the mounting fixture and the second body is pressed downwardly. According to the mounting fixture provided by the embodiment of the invention, the mounting fixture is matched with the conductive wire connector for performing connection of the conductive wire, and a step of manually twisting the conductive wire existing in the prior art is not required in the connection process, so that the connection efficiency can be improved.
