For example: the protective cover body 10 is internally recessed to form an accommodating groove, the plug can be accommodated in the accommodating groove, in addition, a protruding part is formed on the side wall of the accommodating groove, a recessed part is correspondingly arranged on the plug, and the protruding part is clamped in the recessed part, so that the connection between the plug and the protective cover body 10 can be realized; or a second threaded hole is formed in the protective cover body 10, a second through hole is formed in the plug, and the bolt penetrates through the second through hole and then is screwed into the second threaded hole, so that the protective cover body 10 and the plug are connected.
The installation process of the connecting wire protective cover for the railway vehicle provided by the embodiment is as follows: when the vehicle is marshalled, namely the plug on the connecting wire at the rear part of the front carriage is separated from the socket at the front part of the rear carriage, and simultaneously the plug on the connecting wire at the front part of the rear carriage is separated from the socket at the rear part of the front carriage, after that, the protective cover body 10 is covered outside the socket at the rear part of the front carriage, and the protective cover body 10 is connected to the junction box at the rear part of the front carriage; in addition, the plug at the tail end of the connecting line on the junction box at the rear part of the front carriage is installed on the protective cover body 10, so that the installation of the protective cover of the connecting line of the rail train is realized.
In the protective cover for the connecting line of the rail train provided by the embodiment, the protective cover body 10 covers the outer side of the socket, and the protective cover body 10 is detachably connected with the junction box, and the protective cover body 10 is also used for installing a plug; the protection cover body 10 can be used for installing a plug on the same junction box as the socket while protecting the socket, and the space of the junction box occupied by an empty installation plate for installing the plug is avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
