Abstract
The utility model relates to a terminal box comprising a box body and a binding post arranged inside the box body. A plurality of installation cavities are arranged on the box body; each of the installation cavities is provided with one binding post; a lead jack corresponding to each binding post is arranged at a front end of the box body; and an upper end of the box body is provided with a hole. The binding post is integrally a rectangular structure which is transparent at two ends; an upper end face of the binding post is provided with a plurality of bolt installation holes which are arranged corresponding to the hole at the upper end of the box body; a bolt is arranged on an upper end face of the box body, and a screw portion of the bolt is connected with the binding post in the box body through the bolt installation hole; with rotation of the bolt, the binding post is driven to rise integrally; and a lead can be compressed and connected with an lower end face of the binding post through a conductive copper member. With adoption of the above structure, the installation method of the lead is substantially improved, so that the installation of the lead is firmer; the integral performance of the electric energy meter is more reliable; and the installation is move convenient and the high practicability is realized.
Description
Technical field
The utility model relates to a kind of terminal box that is applied on electric energy meter.
Background technology
Be used at present the terminal box on electric energy meter, be all that the employing screw screws to complete the installation to wire, at first wire inserted in connection terminal, be placed on the conductive copper part, then pass through rotary screw, screw is downward immediately, completes the compression of wire is installed, this mounting means, have many drawbacks: the surface of contact of wire between screw and conductive copper part is little, connect also reliably not, wire is easily deviate from, and causes the electric energy meter unstable properties.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provide a kind of simple in structure, connect reliable, the terminal box of stable performance.
for achieving the above object, the utility model adopts a kind of terminal box, comprise box body, be arranged on the connection terminal in box body, be formed with a plurality of installation cavitys on described box body, be provided with a connection terminal in each installation cavity, corresponding each connection terminal of front end at box body offers wire jack, the upper end of box body arranges porose, the connection terminal one-piece construction is the penetrating rectangles in two ends, the upper surface is provided with a plurality of screw mounting holes, the hole of the corresponding box body of screw mounting hole upper end arranges, described screw is arranged on the upper surface of box body, connection terminal in the screw portion of screw and box body links together by screw mounting hole.
connection terminal has been broken through traditional structure, adopt the structure of rectangle to be arranged in the terminal box box body, and be formed with screw mounting hole in the upper end, screw is arranged in the upper end hole of terminal box, screw portion is connected with the upper surface of connection terminal, when installing, wire only needs to insert from the wire jack of terminal box front end, be seated on the conductive copper part that is connected with wiring board, then pass through rotary screw, can drive connection terminal whole to rising, wire just can compress with the lower surface of connection terminal by the conductive copper part and be connected, the joint face of this mode wire and conductive copper part will be far longer than the mode that in tradition, direct employing screw lower surface compresses, and connect reliable, performance is more stable, easy for installation.
The utility model further arranges again, all is provided with trapezoidal bulge-structure on the left and right end face of described terminal box.
On supporting electric energy meter base, the position of terminal box be used for to be installed, arranged on left and right sides is provided with the trapeze cut suitable with trapezoidal bulge-structure, and terminal box can be directly be connected with trapeze cut close-fitting on base by trapezoidal projection, and installation, replacing are conveniently.
The utility model further arranges again, is provided with four connection terminals in box body, and corresponding each connection terminal in the upper surface of described terminal box vertically forms two holes, and it is corresponding with the hole of box body upper surface that the upper surface of each connection terminal is formed with two holes.
In sum, the beneficial effects of the utility model are: by said structure, greatly improve the mounting means of wire, made the installation of wire more fastening, and the performance of electric energy meter integral body and then more reliable, and easy for installation, very practical.
