Abstract
Disclosed is a three-phase electric energy meter, comprising a current terminal sleeve and a manganin diverter connected with the current terminal sleeve, wherein both the current terminal sleeve and the manganin diverter are provided with anti-skidding grooves for increasing frictional force; the inner wall of the bottom of the current terminal sleeve is provided with anti-skidding grooves; both the upper surface and the lower surface of the connecting surface of the manganin diverter and the current terminal sleeve are provided with anti-skidding grooves; and the current terminal sleeve and the manganin diverter are connected via a screw. When the wires are wired, the screw is downwardly screwed to push the manganin diverter to the bottom of the current terminal sleeve till the manganin diverter and the current terminal sleeve simultaneously clamp the wires. The anti-skidding grooves in the two clamping surfaces can enhance the frictional force between the wires and the clamping surface, thereby making the wire connection be stable and reliable and improving the security and stability of the electric meter.
Description
Technical field
The utility model relates to a kind of three-phase electric energy meter, particularly a kind of wire connecting fabric of three-phase electric energy meter.
Background technology
At present, the electrical wire wiring part in the electric energy meter, the mode that adopts screw to connect is clamped on electric wire in the current terminal sub-set more, and the current terminal sub-set is a plane, and electric wire is many to come off easily because of fastening not, or pulls easily because of external force and to drop out, and has potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of electric wire to connect safe and reliable electric energy meter.
This three-phase electric energy meter that the utility model provides comprises current terminal sub-set and connected manganese copper diverter, on described current terminal sub-set and the manganese copper diverter anti-slip tank that can increase friction force is arranged all.
The anti-slip tank that described current terminal puts is positioned at its bottom surface inwall.
The upper and lower surface of described manganese copper diverter and described current terminal sub-set joint face has anti-slip tank.
Described current terminal sub-set and manganese copper diverter are connected by screw.
Current terminal sub-set of the present utility model bottom surface inwall is with anti-slip tank, and the manganese copper diverter top and bottom are also with anti-slip tank, and current terminal sub-set and manganese copper diverter are connected by screw.When electrical wire wiring, be rotated down screw, screw advances the bottom surface of manganese copper diverter to the current terminal sub-set, until manganese copper diverter and current terminal sub-set clamp electric wire simultaneously, anti-slip tank on two clamping surfaces can increase the friction force between electric wire and the clamping surface, make the stable connection of electric wire reliable, strengthen security, the stability of ammeter.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the assembling synoptic diagram of manganese copper diverter among Fig. 1, current terminal sub-set, PCBA and end box.
Fig. 3 is the syndeton synoptic diagram of current terminal sub-set, manganese copper diverter among Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, this three-phase electric energy meter that the utility model provides comprises box 1, end box 2, end cap 3, current terminal sub-set 4, manganese copper diverter 5, PCBA6.There is the anti-slip tank 8 that can increase friction force the bottom surface inwall of current terminal sub-set 4 and the top and bottom of manganese copper diverter 5.The connecting line of manganese copper diverter 5 rear ends is connected by screw 7 with current terminal sub-set 4 with PCBA welding, front end.
Concrete assembling process is as follows: connecting line and the PCBA6 with manganese copper diverter 5 welds first, again manganese copper diverter 5 and current terminal sub-set 4 are assembled, three's assembly parts are packed in the end box 2, PCBA6 is fixed on the end box 2 simultaneously, cover at last box 1, load onto end cap 3 and get final product.
