Abstract
The utility model discloses a wire holder for an electric energy meter, which comprises a wire holder body and a wiring port. The wiring port comprises a conductive adapter sleeve connected with a main body and a copper lug plate inserted into the adapter sleeve. The adapter sleeve and the copper lug plate are provided with screw holes respectively. The wire holder of the utility model greatly reduces the used copper material and effectively saves the cost by using a mode that the adapter sleeve with the copper lug plate adopts separated conductive structure and fixing structure. Meanwhile, the adoption of a fixed sheeting structure of the copper lug plate changes the original connection mode of pressing and connecting wires by trip bolts, thereby reducing the damage ratio to wires and further enhancing the reliable contact of wire cables and the excellent conductivity.
Description
Technical field
The utility model relates to a kind of connection box of electric energy meter seat, particularly a kind ofly have that cost is low, the firm characteristics of wiring comprise junction block body and Wiring port connection box of electric energy meter seat.
Background technology
Electric energy meter need use the connection box of electric energy meter seat when inserting electrical network, and the connection box of electric energy meter seat comprises the input and output Wiring port.The whole requirement of this port has very high insulating property and physical strength, normally annotates with hot pressing of bakelite material or heat to form.As shown in Figure 1, the traditional design current-carrying part is that it is connected internally to sampling, control and metering circuit to ammeter with full copper rod processing, among the outside access of ammeter power supply grid.So every Wiring port all must consume more copper material, the power of ammeter metering is big more, and electric current is also big more, and required copper rod sectional area is also big more, and the consumption of copper material is also just many more.In today that the copper material price rises steadily, the cost of every Wiring port of ammeter has also accounted for the quite great proportion of the whole price of ammeter.And the traditional wired port adopts the direct fixing cord of screw, and long-term use causes the wearing and tearing of plain conductor easily, thereby has reduced the fastness of wiring.
The utility model content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of low cost of manufacture is provided, the firm nonabradable connection box of electric energy meter seat of wiring.
Technical scheme: the utility model discloses a kind of connection box of electric energy meter seat, comprise junction block body and Wiring port, described Wiring port comprises conduction fixing sleeve that is connected with body and the lug that inserts fixing sleeve; Be respectively equipped with screw on described fixing sleeve and the lug.
In the utility model, described fixing sleeve is the zinc-plated fixing sleeve of iron and steel material quality, can reduce the manufacturing cost of Wiring port thus greatly.
Beneficial effect: connection box of electric energy meter seat described in the utility model because the fixing sleeve that has adopted conductive structure to separate with fixed sturcture adds the mode of lug, greatly reduces the use of copper material, effectively the cost of Jie Yueing.Adopt the fixing structure of compressing tablet of lug simultaneously, changed the connection mode of former cause trip bolt crimping lead, reduced the damage ratio of lead, also strengthened the reliability of cable contact, the formedness of conduction.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the Wiring port synoptic diagram of prior art integral structure.
As shown in Figures 2 and 3, the Wiring port described in the utility model comprises conduction fixing sleeve 2 and the lug 3 that inserts fixing sleeve; Be respectively equipped with fastening screw on described fixing sleeve 2 and the lug 3.
As shown in Figure 4, the conduction fixing sleeve 2 of Wiring port is connected with junction block body 1, and lug 3 one ends insert fixing sleeve, and the other end stretches out.Adopting thickness in the present embodiment is that the copper sheet of 2.5mm is cooked lug plate 3, make a wire clamp at electrical network input wires port, after lead inserts fixing sleeve 2, can constantly tighten up lug 3 with screw precession screw, the incoming line of power supply is contacted reliably with being connected copper sheet, install firmly.
Described fixing sleeve is the zinc-plated fixing sleeve of iron and steel material quality.
The utility model provides a kind of thinking and method of connection box of electric energy meter seat; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
