Description

The special junction box of kilowatt-hour meter

The utility model relates to a kind of terminal box of power line.

In the prior art, it is 95220254 utility model patent that Patent Office of the People's Republic of China on December 11st, 96 announced the patent No., it comprises terminal box insulation box body and is loaded on copper bar in the box body, the crimping screw that can connect house lead in W is arranged on the termination of copper bar, described copper bar is two bar insulations bar shaped copper bar arranged side by side or two convex copper bars that insulation is arranged side by side, copper bar exposes the surface of box body except that the end portion that the crimping screw is arranged, remainder all is embedded in the insulation box body, the bottom of copper bar and box body is drilled with a plurality of cross under type plug wire holes, and corresponding each the cross under type plug wire hole place of the upper vertical of copper bar and box body is equipped with the cross-under screw.Rely on the space between described cross-under screw and the plug wire hole wall can insert terminal, behind the lower end head extruding plug wire hole wall of described screw terminal is electrically connected with the plug wire hole wall behind the tighten the screws.But the screw termination and the easy loose contact of terminal of rotating cause terminal place resistance to become big, thereby the heating phenomenon occurs.

The purpose of this utility model is to provide a kind of outlet terminal and special junction box that goes out the good kilowatt-hour meter that contacts of wire terminal of making.

The technical solution of the utility model is: a kind of special junction box of kilowatt-hour meter, comprise housing, be fixed in the bus row of the panel below in the described housing, the upper end is exposed to described bus row's upper surface and the crimping screw that is threaded with described bus row, described panel is provided with a plurality of screw holes, be inserted with terminal screw in the described screw hole, the position of corresponding described screw hole is provided with a plurality of tubular hanging and connects cover in the space of described panel below, described bus row's the line ball pawl that extends forward is inserted in described hanging in the inner chamber that connects cover, the described top that connects cover of hanging is threaded with the threaded shank of described terminal screw, and described hanging on the housing that connects the cover outside has wiring hole.

The utility model compared with prior art has following advantage:

Connect the line ball pawl of cover in the inner chamber and maintain static owing to be inserted in to hang, connect cover and be connected and hang with the screw flight of the terminal screw of top, therefore when rotating terminal screw, can more than move to hang and connect cover, thereby make gap smaller between the lower surface hang the lower inner wall that connects cover and line ball pawl, the terminals that insert in this gap can be electrically connected in clamped realization, and this clamping mode connects reliable, and is simple to operate.

The utility model will be further described below in conjunction with drawings and Examples:
