Description

An electric energy meter with a lug

technical field

The utility model relates to the technical field of electric energy meters.

Background technique

At present, the use of electric energy meters is more and more extensive, and there are a large number of electric energy meters in the fields of buildings, electric power, and agriculture. Traditional electric energy meters are usually connected by bolts, that is, there are several connection bolts at the end of the electric meter, and the wires are wound on the bolts, and then the bolts are tightened to complete the wiring.

However, this wiring method often has a virtual connection, especially when the current is large, leakage at the virtual connection often occurs, and causes the tail of the electric energy meter to be burned. Especially in agricultural irrigation and other fields that require frequent replacement of electric meters or wiring, due to frequent screwing of bolts, it is more likely to cause loosening of the wiring, which poses a great potential safety hazard.

Utility model content

The technical problem to be solved by the utility model is to provide an electric energy meter with a connecting lug for the above-mentioned deficiencies in the prior art. The electric energy meter aims at the defects of the traditional electric energy meter and improves the wiring mode of the traditional electric energy meter by introducing the connecting lug. , avoid loose bolts and poor contact caused by frequent screwing of bolts, and prevent the tail of the electric energy meter from being burned.

In order to solve the above technical problems, the technical solution adopted by the utility model is: an electric energy meter with a wiring nose, which includes the electric energy meter body, the electric energy meter body is provided with a wiring groove and a protective cover for covering the wiring groove, the wiring groove There are wiring bolts inside, and a gap for the power supply line to pass through on the protective cover. In addition, it also includes a wiring nose. One end of the wiring lug is a connecting plate, and the other end is a wiring tube. The wiring tube is hollow and has a Opening, the connecting plate is provided with screw holes, the wiring lug is connected with the electric energy meter body through the screw holes and wiring bolts, and the wiring tube passes through the gap so as to be located outside the protective cover. Whenever connecting wires, there is no need to twist the bolts, just wrap the wires on the wire tube of the terminal lug, or set a wire clip on the wire and clamp the wire clip directly on the wire tube, after the wiring is completed , Insulation tape should also be wrapped around the outside of the wiring tube to ensure safety.

Preferably, each lug has two screw holes.

Preferably, the electric energy meter body is connected with four lugs.

Preferably, the lug is made of copper.

Preferably, the lug is made of aluminum.

The beneficial effects produced by adopting the above-mentioned technical solution are: the utility model improves the tail structure of the traditional electric energy meter, and adds a wiring nose on the basis of the traditional electric energy meter, thereby changing the wiring mode of the electric energy meter and overcoming the traditional wiring. The poor contact phenomenon existing in the connection method avoids the disadvantages of frequent screwing of the bolts in the traditional connection method. The utility model not only makes wiring safer and quicker, but also reduces the risk of burning the tail of the electric energy meter, prolongs the service life of the electric energy meter, has the characteristics of simple structure and low cost, and is very practical.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Example 1:

As shown in Figures 1 and 2, an electric energy meter with a wiring lug includes an electric energy meter body 1, and the electric energy meter body 1 is provided with a wiring groove 2 and a protective cover 3 for covering the wiring groove. Wiring bolts 6, the protective cover 3 is provided with a gap 4 for the power supply line to pass through, and there are four wiring positions in the wiring slot 2, each wiring position contains two wiring bolts 6, and the device has four copper wiring lugs in total. 5. One end of the connection lug 5 is a connection plate 7, and the other end is a connection tube 8. The connection tube 8 is hollow and has an opening at the end far away from the connection plate 7. The connection plate 7 is provided with two screw holes 9, and the connection nose 5 passes through the screw. The hole 9 and the terminal bolt 6 are connected to the main body 1 of the electric energy meter, and the terminal tube 8 passes through the gap 4 so as to be located outside the protective cover 3 .

When using the utility model to connect wires, there is no need to twist the wire bolts 6, it is only necessary to wind the wires on the wire tube 8 of the wire nose 5, or set wire clips on the wires and directly clamp the wire clips on the wire tube 8 After the wiring is completed, insulating tape should also be wrapped on the outside of the wiring tube 8 to ensure safety.

The utility model improves the tail structure of the traditional electric energy meter, and adds a wiring nose on the basis of the traditional electric energy meter, thereby changing the wiring mode of the electric energy meter, overcoming the poor contact phenomenon existing in the traditional wiring mode, and avoiding the traditional Disadvantages of frequent screwing of bolts in wiring mode. The utility model not only makes wiring safer and quicker, but also reduces the risk of burning the tail of the electric energy meter, prolongs the service life of the electric energy meter, has the characteristics of simple structure and low cost, and is very practical. the
