Technical Field

Background

The electric energy is widely applied in life due to the characteristics of low price and easy availability, but the electric energy also has certain danger, the electric energy is easy to cause fire, and great threat is caused to the life safety and property safety of users.

One measure to solve the above problem is to monitor the use of electrical energy so that the user can know the current electrical energy use in time. For example, the electric sensor is arranged at home or in a working place, so that the electric energy use is monitored in real time, an electric fire accident can be conveniently found in time, and the electric fire accident can be used as early warning in advance or measures can be taken in time, so that the life safety and property safety of a user can be powerfully guaranteed. Of course, it can be understood that monitoring the use of electric energy also facilitates the user to grasp the electricity utilization situation in real time, so as to reduce the possibility of electric leakage and even electricity stealing.

The current electric energy monitoring device provides a current transformer through which the live wire and the zero wire of the air switch pass simultaneously to measure the current difference of the zero wire or the live wire, thereby obtaining the difference by calculation. The current transformer is large in size and needs to penetrate through a live wire and a zero line at the same time, so that the current transformer is inconvenient to install on the air switch. It is further noted that the current transformer is typically implemented as a ring-shaped mutual inductor, which needs to be fixedly mounted to both the neutral position and the live position of the air switch. The air switch with the current transformer obtained by installation is not firm and has poor external impact resistance, so that the detection result of the current transformer can be influenced.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 3A, a power detector 1 according to a preferred embodiment of the present invention is illustrated. The power detector 1 is adapted to be conveniently mounted to an air switch 2 to detect the current passing through the air switch 2.

The air switch 2 is illustrated in fig. 3, and it will be understood by those skilled in the art that the appearance and structure of the air switch 2 are not limited to those shown in fig. 3, and the power detector 1 may be designed to match with various air switches 2 on the market.

The air switch 2 has an inlet end and an outlet end, and at least one mounting hole is formed at the position of the outlet end for passing through a power supply line, in this embodiment, the number of the mounting holes is two, one mounting hole is used for leading in a live line L, and the other mounting hole is used for leading in a zero line N, wherein the power detector 1 is suitable for being mounted at the outlet end of the air switch 2. Electric power from the public power grid enters from the inlet end of the air switch 2 and is then distributed at the outlet end towards the intended destination by means of the live line L and neutral line N mounted in the mounting hole.

The power detector 1 can be conveniently and stably installed at the outlet end of the air switch 2. In detail, the power detector 1 includes a housing 10, a detecting body 20 and a pair of pins 30, wherein the pins 30 are conductively connected to the detecting body 20, the housing 10 forms a receiving cavity 100, at least a portion of the detecting body 20 is received in the receiving cavity 100 formed by the housing 10, and the pins 30 are mounted to the housing 10. The detection body 20 can be used for detecting data such as current magnitude, voltage magnitude, wire temperature and the like. The pin 30 is used for connecting to the live line L or the neutral line N so that the detecting body 20 can obtain related data.

The housing 10 of the power detector 1 is formed with at least one insertion hole 101, and in this embodiment, the number of the insertion holes 101 is two, two insertion holes 101 correspond to two pins 30, respectively, one of the live wires L is mounted to the pins 30 and passes through one of the insertion holes 101 formed in the housing 10, and one of the neutral wires N is mounted to the other of the pins 30 and passes through the other of the insertion holes 101 formed in the housing 10.

The detecting body 20 may include two transformers 21, at least one temperature sensor 22 and a circuit board 23, wherein the transformers 21, the temperature sensor 22 and the circuit board 23 are electrically connected to each other, and the pins 30 may be conductively connected to the circuit board 23 to collect required data through the pins 30. Preferably, the mutual inductor 21, the temperature sensor 22 and the circuit board 23 are respectively accommodated in the accommodating cavity 100 of the housing 10, and the housing 10 forms a relatively closed accommodating cavity 100 to reduce the possibility of moisture or dust entering. The temperature sensor 22 may be implemented as a thermistor.

The transformers 21 may be a mutual inductor and may be positioned around the locations of the jacks 101, one jack 101 corresponding to each transformer 21. When the live wire L or the neutral wire N passes through the jack 101, the mutual inductor 21 surrounds the live wire L or the neutral wire N, respectively. One of the transformers 21 is connected to one of the pins 30 and configured to sense the hot line L, and the other of the transformers 21 is connected to the other of the pins 30 and configured to sense the neutral line N.

In other words, in the present embodiment, two transformers 21 are employed to detect the live line L and the neutral line N, respectively. As can be seen from the foregoing description, in the current technology, a larger current transformer 21 is usually used, and the live line L and the neutral line N simultaneously pass through the current transformer 21 to measure the current difference between the live line L and the neutral line N. In comparison, the space occupied by a single transformer 21 through which the zero line N and the live line L pass is significantly larger than the space occupied by two transformers 21 through which the zero line N and the live line L pass, respectively. Whereas in one of the power detectors 1 the transformer 21 takes up a large space. In other words, in the present embodiment, the size of the power detector 1 can be reduced relative to the size of the previous power detector 1 having a single transformer 21.

In addition, since the live line L and the zero line N are separately detected, the power detector 1 can timely and respectively grasp the power transmission states of the live line L and the zero line N.

In addition, since the size of the power detector 1 can be reduced, the installation thereof becomes more convenient with respect to the previous large size, and the assembly of the power detector 1 and the air switch 2 can be achieved by inserting the pin 30 of the power detector 1 into the installation hole of the air switch 2 in such a manner as to be conducted to the live line L and the neutral line N installed in the installation hole, respectively. For the live wire L and the zero wire N, the live wire L and the zero wire N respectively extend from the inlet end of the air switch 2 to the outlet end inside the air switch 2, and then continue to extend outward through the jack 101 of the power detector 1.

While the power detector 1 is mounted to the air switch 2, the live line L and the neutral line N are respectively mounted to the power detector 1 and contact with the pin 30 is maintained to acquire data required to be detected through conduction of the pin 30 and the live line L and the neutral line N in a subsequent process.

In detail, the pin 30 has a mounting surface 301, wherein the live line L or the neutral line N is mounted to the mounting surface 301. Generally speaking, the mounting surface 301 of the pin 30 is configured as a flat surface, and then the live wire L or the neutral wire N is pressed by a fastener such as a screw to be restrained against the mounting surface 301 of the pin 30, so as to maintain conduction between the live wire L and the neutral wire N, which is obviously inconvenient during installation, the cross section of the live wire L or the neutral wire N is often circular, and during installation of the live wire L or the neutral wire N on the horizontal mounting surface 301 of the pin 30, an installer needs to pay a great deal of effort to limit the relative movement between the live wire L or the neutral wire N and the mounting surface 301 of the pin 30, so as to reduce the possibility of installation offset of the live wire L or the neutral wire N and the pin 30, but obviously, due to the absence of a positioning element, the installation of the live L or neutral N at the location of the pin 30 tends to be offset.

In the present embodiment, the mounting surface 301 of the pin 30 is provided to be rugged. In detail, the mounting surface 301 of the pin 30 is recessed to form a positioning groove 300, wherein the live wire L or the neutral wire N can be mounted in the positioning groove 300 of the pin 30, so that the live wire L or the neutral wire N can be limitedly mounted to the mounting surface 301 of the pin 30. It is not necessary for the operator to expend excessive effort to maintain the relative positions of the live wire L or neutral wire N and the pin 30. With this arrangement, the power detector 1 can be conveniently mounted to the live line L and the neutral line N.

Further, at least two positions of the mounting surfaces 301 of the pins 30 having a certain interval may be protruded outward to form two protrusions 31, and the positioning groove 300 is formed between the two protrusions 31.

Further, the mounting surface 301 of the pin 30 may provide at least two support positions, three support positions, or more support positions for the live wire L or the neutral wire N, so as to support the live wire L or the neutral wire N while limiting the live wire L or the neutral wire N. In detail, the contour of the positioning groove 300 formed by the mounting surface 301 of the pin 30 is implemented as a rectangular contour in the present embodiment, and the pin 30 gives a supporting force to the live wire L or the neutral wire N at both sides and a bottom side of the position of the positioning groove 300, respectively. In this way, in the installation process, the live wire L or the zero line N may be limited in the positioning groove 300, so that a fixing member, for example, a screw may fasten the live wire L or the zero line N to the pin 30, and the live wire L or the zero line N may not be shifted relatively, as shown in fig. 4.
