3: the current transformer of this band U-shaped copper sheet is owing to be connected the outer copper tip afterbody of plastic terminal box body, this external current transformer has strengthened the volume of whole subassembly, also can occupy the inner space of watchcase because of the bodily form is excessive when time in the watchcase that is assembled into electric energy meter, covert increasing electric energy meter physical dimension and circuit board size;
4: because of the plastic terminal box body is an one-piece construction, it is plastic cement part independently, there is not other parts combination, and copper tip all is directly to insert in the position, the pairing hole of plastic terminal box body by the effect of external force, is to prevent what copper tip from withdrawing by the close-fitting of copper tip and plastic terminal box body body round position is incompatible.Certainly, copper tip can insert just to have transfers to the possibility of coming, in case the copper tip tolerance is negative partially, the tolerance polarization of plastic terminal round position, so copper tip insert the back friction diminish just easily loosening and withdrawed from, copper tip in a single day withdraw from will influence the components and parts that are connected with copper tip (as current transformer, relay, manganese copper diverters etc.), they can cause defectives such as electric property inefficacy because copper tip withdraws from the stress of back generation.
Summary of the invention
The object of the present invention is to provide and a kind ofly can save copper material, reduce the belt current mutual inductor of electric energy meter overall volume and the terminal row of copper tip.
The terminal row of this belt current mutual inductor provided by the invention and copper tip comprises plastic terminal box, copper tip summation current transformer, the elementary copper sheet of current transformer is electrically connected with copper tip, it is characterized in that described copper tip summation current transformer is embedded in the plastic terminal box, by a plastic terminal lid lid jail, make copper tip summation current transformer strong fix.
In order further to make copper tip summation current transformer strong fix, prevent that copper tip from retreating, the interior shape of plastic terminal box and plastic terminal lid can make them close lid back parcel copper tip summation current transformer wherein.Plastic terminal box or plastic terminal cover and are provided with terminal block.
In order to maximally utilise copper material, the elementary copper sheet of described current transformer is yi word pattern.
The present invention is owing to be divided into plastic terminal box and plastic terminal lid with the plastic terminal box body, and the copper tip summation current transformer all embedded in the plastic terminal box, prevent moving of copper tip by the plastic terminal lid, so we can see that the present invention has following advantage:
1: current transformer directly embeds in the gap between the copper tip, has reduced the copper sheet material on the current transformer greatly, has saved cost;
2: copper tip has embedded the inside of terminal board, and copper tip length shortens greatly, and copper tip shortens the weight that has reduced copper material, has saved cost;
3: adopted plastic terminal box and plastic terminal to cover this split-type structural, current transformer and copper tip are wrapped in terminal board and the terminal cap formation space, formed damascene structures, when in the watchcase that is assembled into electric energy meter, current transformer can not take the watchcase inner space again, has reduced electric energy meter physical dimension and circuit board size accordingly yet;
4: the plastic terminal box body of this structure of the present invention, can be very easily at the plastic terminal box and cover terminal block is set, the fore-and-aft direction of copper tip is because the effect shelves of terminal block have been lived the afterbody of copper tip, copper tip withdraws from terminal board no longer easily, has solved electric energy meter and has withdrawed from the defective that the stress of generation causes other device electric property to lose efficacy because of the terminal row copper tip.
