Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
First embodiment
Referring to fig. 1, an embodiment of the present invention provides an electric energy meter cover plate 100, where the electric energy meter cover plate 100 is applied to an electric energy meter, the electric energy meter further includes an electric energy meter body, the electric energy meter cover plate 100 includes a plate body 110 and a conductive piece 120, one end of the conductive piece 120 is connected to an inner side of the plate body 110, and when the plate body 110 and the electric energy meter body are in a closed state, the other end of the conductive piece 120 contacts a zero line in the electric energy meter body. Through the electric energy meter cover plate 100 provided by the embodiment, the electric energy meter cannot be damaged under high-voltage 'electric shock', and the electric energy meter is effectively protected.
In the prior art, in order to pay no electricity, users in some regions may choose to destroy the electric energy meter, and when the users use high-voltage equipment to "shock" the electric energy meter, for example, use a high-voltage electric stick to "shock" the electric energy meter. Due to the high voltage of the electric shock generated by the high voltage electric stick, which is up to thousands of volts, for the current electric energy meter, the internal devices of the electric energy meter are damaged, for example, the internal devices of the electric energy meter are short-circuited, or the devices are burnt out due to the high voltage. At this time, the staff can not perform meter reading operation on the electric energy meter, and meanwhile, the electric energy meter is not damaged in appearance, so that the staff generally recognizes that the electric energy meter per se has a fault, and further the rights and interests of the electric power company are damaged.
In view of the above, the present application provides a new cover plate 100 for an electric energy meter, which can protect the electric energy meter from being damaged when the electric energy meter is subjected to a high voltage "electric shock". The structure thereof will be described in detail below.
The electric energy meter comprises an electric energy meter body and an electric energy meter cover plate 100, the electric energy meter body comprises main circuit modules of the electric energy meter, such as an electric power acquisition module, a communication module and the like, circuits in the electric energy meter are mainly integrated on a circuit board, and the electric energy meter cover plate 100 can be covered and connected with the electric energy meter body to form a complete electric energy meter.
In the embodiment, the cover plate 100 of the electric energy meter includes a plate body 110 and a conductive member 120, wherein, in order to prevent an electricity accident during the use of the electric energy meter, the plate body 110 of the cover plate 100 of the electric energy meter is generally made of an insulating plate body 110, for example, made of a plastic material.
On the one hand, the plate body 110 made of the plastic material can achieve the insulating effect, and on the other hand, the plate body 110 made of the plastic material can be better connected with the electric energy meter body when being connected with the electric energy meter body. Generally, after the plate body 110 is covered on the electric energy meter body, a hot-melt welding mode can be adopted to melt the edge of the plate body 110, which is in contact with the electric energy meter body, so as to realize the fixed connection of the plate body 110 and the electric energy meter body. And after the fixed connection, the user can not take the electric energy meter body and the electric energy meter cover plate 100 apart at will, so that the power utilization safety of the user is ensured, and the user can not take the electric energy meter cover plate 100 apart at will to modify the electric energy meter and other operations, so that the electric energy meter is not easy to damage easily.
Preferably, referring to fig. 2, in the present embodiment, an edge of the plate body 110 of the electric energy meter, which is used for being connected with the electric energy meter body, is configured to be wavy, that is, the edge of the plate body 110 is provided with a plurality of semicircular protrusions 111, the plurality of semicircular protrusions 111 are adjacently disposed, and each semicircular protrusion 111 has the same size.
By arranging the edge of the plate body 110 to be wavy, when the plate body 110 of the electric energy meter is buckled with the electric energy meter body, a plurality of point contacts are substantially formed between the plate body 110 and the electric energy meter body, namely, the vertex of each semicircular protrusion 111 is contacted with the edge of the electric energy meter body, and other positions between two adjacent semicircular protrusions 111 are substantially gaps. Through this arrangement, when carrying out fusion welding, for example adopt the form of ultrasonic wave to weld, can melt every semicircular bulge 111, and then make firmly to be connected between electric energy meter body and the electric energy meter apron 100.
Since each semicircular projection 111 is substantially melted at the time of welding and the volume of the semicircular projection 111 is small, an effect of melting each semicircular projection 111 can be achieved. In the process that the semicircular protrusions 111 melt, the colloid can diffuse towards two ends, so that the diffusion is more uniform, the edges between the electric energy meter cover plate 100 and the electric energy meter body are always in close contact, and the connection is firmer.
Further, although the plate body 110 made of an insulating material has a certain insulating effect, the current object defined as an insulator with a large resistivity of about 10 ohm/m becomes an insulator, and it is understood that the insulator itself is a relative concept, which does not mean that the insulator is not conductive in any case. When a user uses high-voltage equipment to act on the electric energy meter, for example, when a high-voltage electric stick is tightly attached to the electric energy meter cover plate 100 and then is started to work, the high voltage of the high-voltage electric stick can penetrate through the electric energy meter cover plate 100 and damage electronic devices on the electric energy meter body, so that the electric energy meter cannot work.
In view of this, the electric energy meter cover plate 100 provided by the present application includes the conductive element 120, and since the conductive element 120 is connected to the electric energy meter plate body 110 and the zero line respectively, when the high-voltage electric stick works, the high-voltage electricity is conducted away from the zero line, so that the components in the electric energy meter are not damaged by the high-voltage electricity, and the normal operation of the electric energy meter is ensured.
The conductive device 120 of the present embodiment is made of a conductive material, and may be a metal conductive device 120, for example, the conductive device 120 is made of iron, and certainly, it may also be a non-metal conductive device 120, for example, the conductive device 120 is made of graphite, which is not limited in this application.
Moreover, because the electric energy meter shakes during transportation or installation, if the conductive member 120 is rigidly connected, a fault that the conductive member 120 is broken or bent during shaking may occur, so that the conductive member 120 cannot communicate the cover plate 100 of the electric energy meter with the zero line, and the electric energy meter still has a risk of a fault due to high voltage.
In view of this, the conductive member 120 provided in the present application is an elastic conductive member 120, and when the plate body 110 and the electric energy meter body are in a covering state, the elastic conductive member 120 is in a compressed state.
The elastic conductive member 120 may be a spring or a leaf spring. When the electric energy meter shakes under the action of external force, the external force is converted into elastic potential energy of the elastic conductive member 120, and the conductive member 120 is not easily damaged.
Meanwhile, in order to prevent the displacement of the conductive element 120 during the use process, that is, the conductive element 120 no longer contacts with the zero line due to shaking or other reasons, in this embodiment, the connection between the conductive element 120 and the board body 110 and/or the connection between the conductive element 120 and the board body 110 need to be fixed.
As one implementation manner of the present application, one end of the conductive element 120 is fixed to the board body 110, and the other end of the conductive element 120 is a free end. That is, the position of the conductive element 120 is preset, so that when the board body 110 and the electric energy meter body are in a closed state, the free end of the conductive element 120 just abuts against the zero line of the electric energy meter. Meanwhile, the conductive element 120 is fixed to the board body 110, so that the other end of the conductive element 120 is not easy to slide on the neutral line, and the conductive element 120 is more firmly connected.
The fixing between one end of the electric component and the plate body 110 also includes two methods:
the first method comprises the following steps: one end of the conductive member 120 is directly and fixedly connected to the cover plate 100 of the electric energy meter, that is, after the conductive member 120 is connected to the cover plate 100 of the electric energy meter, the cover plate 100 of the electric energy meter cannot be detached from the conductive member 120. For example, the cover plate 100 of the electric energy meter is fixedly connected to the conductive member 120 by welding. Taking the conductive member 120 as a spring as an example, one end of the spring is welded to the electric energy meter cover plate 100 by thermal welding, and the other end is a free end. Or, one end of the spring is connected to the inner side of the electric energy meter cover plate 100 by using adhesive glue, and the inner side described in this embodiment refers to a side of the body facing the electric energy meter body after the body and the electric energy meter body are covered.
And the second method comprises the following steps: the fixing between the conductive member 120 and the conductive member 120 is realized by arranging the mounting portion on the inner side of the plate body 110, and after the conductive member 120 is connected with the electric energy meter cover plate 100 in front, the electric energy meter cover plate 100 can be separated from the conductive member 120. Specifically, the inner side of the board body 110 provided in this embodiment is provided with a mounting groove and a baffle, one end of the conductive member 120 is disposed in the mounting groove, and the conductive member 120 is clamped to the baffle. Taking the conductive member 120 as the spring conductive member 120 as an example, the end of the spring is connected to the mounting groove, and the baffle is further clamped between the gaps of the spring, so as to fix the spring.
As a second implementation manner of this embodiment, one end of the conductive element 120 is fixed to the zero line of the electric energy meter body, and the other end of the conductive element 120 is a free end, so that when the board body 110 covers the electric energy meter body, the conductive element 120 can be in a compressed state, and then the conductive element 120 and the board body 110 can be abutted against each other.
The conductive member 120 and the electric energy meter body can be fixed by welding.
As a third implementation manner of this embodiment, one end of the conductive element 120 is fixed to the board body 110, and the other end of the conductive element 120 is also fixed to the zero line of the electric energy meter body.

By arranging the conductive piece 120 on the cover plate 100 of the electric energy meter, high voltage can be guided to the zero line through the current board cover body and the conductive piece 120 when the electric energy meter 200 is impacted by high voltage, so that electronic devices in the current meter cannot be damaged, and the electric energy meter is effectively protected.
In addition, by setting the conductive element 120 as the elastic conductive element 120, even if the conductive element 120 shakes, the connection between the conductive element 120 and the cover plate 100 of the electric energy meter and the zero line can be ensured, and the connection stability of the conductive element 120 is enhanced.
To sum up, the embodiment of the utility model provides an electric energy meter apron and electric energy meter, this electric energy meter apron are applied to the electric energy meter, and the electric energy meter still includes the electric energy meter body, and the electric energy meter apron includes plate body and electrically conductive piece, and the one end of electrically conductive piece is connected with the inboard of plate body, and when the plate body was in the lid with the electric energy meter body and closes the state, the other end of electrically conductive piece contacted with this internal zero line of electric energy meter. Because including electrically conductive piece on the electric energy meter apron that this application provided, and electrically conductive piece and the zero line contact of electric energy meter, consequently utilize high-voltage electrical equipment to carry out "electric shock" the back to the electric energy meter when the user, high-voltage electricity is passing the plate body after, can conduct to the zero line along electrically conductive piece on to lead away high-voltage electricity by the zero line. In the process, high voltage can not be conducted to the device of the electric energy meter body, so that the device can not be damaged, and the effect that the electric energy meter can not be damaged under high-voltage electric shock is realized.
