[0013] The utility model provides a kind of matching heavy-duty truck's quick plug-in type combination wire harness, and its characteristics are as shown in Figure 1 Wire harness is constituted by main wire harness 6 and roof branch wire harness 1, top cabinet branch wire harness 2, cab branch wire harness 3, chassis front branch wire harness I 4, chassis rear branch wire harness II 5 etc.. Main wire harness only needs to customize length, and standard interval is set on main wire harness, and plug-in port is set every standard interval for the plug-in of each branch wire harness, which can be applied to all heavy-duty trucks with the same wheelbase, without the need for design changes according to configuration again;Each branch wire harness is designed for each specific component, and the same configuration item for different wheelbase can be recycled using branch wire harness, according to the location of each configuration on the vehicle, plug into the corresponding position of main wire harness.

[0014] According to the specific total length of the vehicle model, standard interval is set, plug-in is set every standard interval on main wire harness, the plug-in head structure on main wire harness is male head, and the starting end of branch wire harness is also provided with plug-in, and the plug-in head structure on branch wire harness is female head. Figure 2, specifically by the shell 11, the shell 12, the spring 13, the positioning bead 14, the female terminal 15. Among them, the branch wire harness is pressed into the shell 11, the wire harness is connected with the internal female terminal 15, the shell 12 can be moved backward (the direction shown in the drawing is left) by pressing the spring 13, after moving backward to the front opening structure and passing the positioning bead 14, the positioning bead 14 can move outward, after releasing the shell 12, the shell 12 can be reset under the action of the spring 13, and the positioning bead 14 is pressed back to the inside.
