Abstract
The utility model discloses a terminal box. The terminal box comprises a box body (1), two copper joints (2) and a mutual inductor (3), the two copper joints are embedded in the box body (1), and the mutual inductor is electrically connected with two annular copper conducting strips (4). The terminal box also comprises two copper connecting heads (5), and the two annular copper conducting strips (4) are respectively fixed between the two copper connecting heads (5) and the two copper joints (2). The above terminal box is low in production cost.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of terminal box.
Background technology
The terminal box of prior art comprises box body, two copper sleeves and a mutual inductor, and described two copper sleeves are embedded in the box body; Be respectively equipped with two columniform copper connectors between described two copper sleeves and the mutual inductor, weld with two copper sleeves and a mutual inductor respectively at the two ends of described two copper connectors; The xsect of described copper sleeve is square.There is following defective in the terminal box of said structure in the use procedure of reality: owing to be welding between copper connector and copper sleeve, the mutual inductor, so its production process complexity, thereby cause its production cost higher.In addition, the cylindrical, copper web member has increased the application of copper, thereby has also increased to a certain extent the production cost of terminal box.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of production cost low terminal box.
The technical solution of the utility model is, a kind of terminal box is provided, and comprises box body, two copper sleeves and a mutual inductor, and described two copper sleeves all are embedded in the box body; Be electrically connected with two annular copper conducting strips on the described mutual inductor; Described terminal box also comprises two copper connecting heads, and described two annular copper conducting strips are separately fixed between two copper connecting heads and two copper sleeves.
One end of described two copper connecting heads is provided with a screw rod, and the other end of described two copper connecting heads is provided with a threaded hole; Described two copper connecting heads are threaded with two copper sleeves.
The xsect of described copper sleeve is circular.
After adopting above structure, the utility model compared with prior art has the following advantages:
Two annular copper conducting strips of the utility model terminal box are separately fixed between two copper connecting heads and two copper sleeves, and the three is for being fixedly connected with, so installation procedure is simple, so that its production cost is low.And use the annular copper current-conducting piece to replace the cylindrical, copper web member, reduce the application of copper, thereby also reduced to a certain extent the production cost of terminal box.
As improvement, the xsect of described copper sleeve is circular, and square than before reduced equally the application of copper, thereby also reduced to a certain extent the production cost of terminal box.
Description of drawings
Fig. 1 is the structural representation of the utility model terminal box.
Shown in the figure 1, box body, 2, copper sleeve, 3, mutual inductor, 4, copper current-conducting piece, 5, copper connecting head, 5.1, screw rod, 5.2, threaded hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of terminal box of the utility model comprises box body 1, two copper sleeves 2 and a mutual inductor 3, and described two copper sleeves 2 all are embedded in the box body 1; Be electrically connected with two annular copper conducting strips 4 on the described mutual inductor 3; Described terminal box also comprises two copper connecting heads 5, and described two annular copper conducting strips 4 are separately fixed between two copper connecting heads 5 and two copper sleeves 2, and namely a copper connecting head 5 is fixed on a copper current-conducting piece 4 on the copper sleeve 2; Mutual inductor 3 is fixed between two copper sleeves 2.
One end of described two copper connecting heads 5 is provided with a screw rod 5.1, and the other end of described two copper connecting heads 5 is provided with a threaded hole 5.2; Described two copper connecting heads 5 are threaded with two copper sleeves 2, and namely the screw rod 5.1 of copper connecting head 5 is threaded with the screw of copper sleeve 2.
The xsect of described copper sleeve 2 is circular.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
