Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Fig. 1-3, this table case of this application includes watchcase 1 and the table lid 2 of fixing on watchcase 1, is equipped with the fixed baffle 3 of power supply table installation in the watchcase 1, is equipped with the mounting hole 31 that is used for the fixed single-phase table of installation and is used for the pilot hole 32 of the fixed three-phase table of installation on this baffle 3, and mounting hole 31 and pilot hole 32 correspond the interval distribution on baffle 3 according to the ammeter kind and the size of a dimension that correspond separately, so, realize that the table case both is applicable in the single-phase table of installation, and is applicable in the three-phase table of installation again.

In a specific design, the mounting hole 31 and the assembling hole 32 are both of a three-point structure which can form a triangular shape, and the triangular structure is stable, so that the meter can be more firmly mounted by adopting the point-like mounting structure. Preferably, the triangle formed by the three-point structure is an isosceles triangle.

In view of the different quantity of meters required to be installed in the meter box in different regions and different countries, the quantity of the clapboards in the meter box can be different, in the embodiment, the clapboards 3 are provided with three clapboards which are respectively arranged at the upper end part, the middle part and the lower end part of the cavity of the meter box 1 so as to divide the cavity of the meter box 1 into an upper section, a middle section and a lower section, wherein, because the volume of the single-phase meter is smaller than that of the three-phase meter, more single-phase meters can be installed in one meter box, correspondingly, the three clapboards 3 are provided with installation holes 31, and because the volume of the three-phase meter is larger, in order to avoid enough proper space between the meters for installation and placement, the installation holes 32 are arranged on the clapboards 3 which are arranged at the upper end part and the lower end part of the cavity of the meter box 1, as shown in fig. 2 in particular.

In this embodiment, three sets of the mounting holes 31 are uniformly distributed on the same partition plate 3, and two sets of the assembly holes 32 are arranged on the same partition plate 3.

Continuing with fig. 2 and 3, the lower end of the inner wall of the watch case 1 is provided with a three-phase live wire end 4 and a neutral wire end 5, one live wire end having m live wire branch points. Because some countries and regions need to adopt the circuit structure of two-phase wire system, require that a plurality of ammeter can be carried on simultaneously in a table case, need not carry out extra branch design to the circuit simultaneously, in order to satisfy this kind of demand, table case in this application still includes can concatenate two arbitrary live wire ends in the three-phase live wire end 4 in order to form a copper sheet 6 that has the live wire inlet end of m live wire branch points, and zero line end 5 also is worked as the live wire and is carried out the wiring under this situation to realize two-phase wire system.

Of course, the maximum number of electric meters that can be carried by the live wire in this case is m, for example, m is 10. Obviously, the copper sheet 6 is only for special requirements, in other words, for a normal three-phase four-wire system or three-phase three-wire system or even a single-phase meter, the copper sheet 6 is not needed, so that in this case, the copper sheet 6 is removed.

Just as background art says, current ammeter is when carrying out the zero line end installation, need drill on the zero line end earlier, then correspond the zero line and the zero line end of ammeter and screw up fixedly with screw and nut, because screw nut is not hard up easily, cause the zero line to break away from very easily, influence the meter work, but this application adopts to establish zero line end that can supply the electric meter on zero line end 5 and cup joints the zero line terminal 51 of fixed wiring, so, only need cup joint the zero line end of ammeter on this zero line terminal 51, then screw up with the nut, just reduced the trouble that the screw drops and brings, and the assembly is simpler.

While embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the claims and their equivalents.
