Abstract
The utility model relates to a fixing structure of an electronic type electric meter loading terminal, which comprises a jack and screws. The utility model is characterized in that a hollow housing used for accommodating a loading terminal is arranged in the jack of the loading terminal; the screws are tightly locked on the top surface of the hollow housing, wherein the bottom surface of the hollow housing can be a circular arc concave surface; an inserting piece in an arc shape can also be arranged in the hollow housing. The utility model has the technical scheme that the maximum contact area of the loading wiring is ensured by the arrangement of the hollow housing and the inserting piece; heat generation in a heavy current of the terminal is prevented; accidents of burning of terminals and meters are solved because of the oversize current when the electronic type electric meter is used; in addition, the utility model having the structure of the terminal solves the problem of easy loose of loading lines.
Description
Technical field
The utility model relates to a kind of electron watt-hour meter, especially refers to the fixed sturcture of the load wiring end of this electron watt-hour meter.
Background technology
As shown in Figure 1, the fixed sturcture of the load wiring end of existing electron watt-hour meter, general load wiring end is directly entered by the jack 1 of shell, directly is pressed on the load line by screw 2 and fixes.
The said fixing mode, because the upper end of load wiring end and screw are to contact, the lower end is that line contacts with the load line mounting hole, therefore, during use, when load current is excessive, causes by heating easily and burn terminal, even the generation of burning table accident.In addition, this fixed form also easily causes the loosening of load wiring end, and dead load line effectively.
The utility model content
The purpose of this utility model be to provide a kind of load line fixing reliable, and can prevent from when big electric current, to quote the fixed sturcture of the load wiring end of terminal excessive heating.
The fixed sturcture of the load wiring end of a kind of electron watt-hour meter provided by the utility model comprises jack and screw, it is characterized in that; Be provided with the hollow housing of a ccontaining load wiring end in the jack of described load wiring end, the end face of described screw and this hollow housing is locked.
In the fixed sturcture of above-mentioned load wiring end, the bottom surface of hollow housing is the circular arc concave panel.
In the fixed sturcture of above-mentioned load wiring end, also be provided with the inserted sheet of an arc surfaced in the hollow housing.
In the fixed sturcture of above-mentioned load wiring end, the locking mode of the end face of screw and this hollow housing adopts screw thread to spin fixing.
In the fixed sturcture of above-mentioned load wiring end, load wiring is pressure-wire or electric current line.
Adopted above-mentioned technical solution, promptly by the maximum contact area that hollow housing and inserted sheet have guaranteed load wiring is set, prevent from when big electric current, to cause terminal heating, solved the electronic electric meter accident of the excessive burning terminal that causes of electric current or burning table in use.In addition, the structure of the utility model terminals has solved the easily loosening problem of load line.
Description of drawings
Fig. 1 is the synoptic diagram of fixed sturcture of the load wiring end of existing electron watt-hour meter;
Fig. 2 is the structural representation of electron watt-hour meter of the present utility model;
Fig. 3 is the A-A sectional view among Fig. 2.
Embodiment
Shown in Fig. 2～3, the utility model, it is a kind of fixed sturcture of load wiring end of electron watt-hour meter, comprise jack 3 and screw 4, in the jack 3 of load wiring end, be provided with the hollow housing 5 of a ccontaining load wiring end 6, the bottom surface of hollow housing 5 is the circular arc concave panel, and screw 4 is locked with the end face of this hollow housing 5, and locking mode adopts screw thread to spin fixing.
Also be provided with the inserted sheet 7 of an arc surfaced in the hollow housing 5, it is between terminals 6 and screw 4.
Load wiring is pressure-wire or electric current line.
The utility model makes load line fixing reliable, and especially the mode of connection has guaranteed maximum contact area, prevents big current terminal heating.
Above-mentioned only for the use of explanation the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, therefore all technical schemes that are equal to also should belong to category of the present utility model, and should be limited by individual claim.
Claims (5)
