Description

Power strip with overload protection

technical field

The utility model relates to a plug-in row, in particular to a plug-in row with overload protection function.

Background technique

The socket is a kind of socket, but it is a porous socket formed by putting multiple sockets together. It consists of a shell, a power cord, and multiple jacks. Can realize a multi-purpose like this, has not only saved space but also saved circuit, is a very simple and practical invention. Usually, most of the sockets are movable porous sockets with power cords and plugs, while sockets usually refer to fixed and mostly five-hole sockets.

With the continuous development of science and technology and the improvement of people's living standards, household appliances occupy a large space in our daily life, especially for urban life, due to environmental constraints, the family is basically dominated by electrical appliances, and in In household use, in order to save unnecessary trouble, people often connect multiple electrical appliances and sockets to one socket. The overload operation of the row will burn out the plug-in row, or even cause a fire, causing immeasurable consequences to people's lives and property.

Utility model content

In order to overcome the shortcomings of the above-mentioned existing products, the purpose of this utility model is to provide a plug-in strip with overload protection function, which adopts an ammeter and a chip inside the shell, and a warning light and a button switch on the surface.

The technical solution adopted in order to achieve the purpose of the utility model is: a plug-in strip with overload protection function, which is characterized in that it is composed of a shell, an ammeter, a chip, a jack area, a button switch, and a warning light; The casing is square, with a power cord on the upper end, a socket area, a button switch, and a warning light on the surface, and an ammeter and a chip inside; pointers and scale intervals are arranged on the ammeter.

The beneficial effects of the utility model are: it can not only measure the current of the power line, but also protect the plug-in strip from overload to prevent accidents; and the utility model is simple in structure, economical, practical, safe and reliable.

Description of drawings

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

Fig. 1 is the structural diagram of the utility model

Figure 2 is a sectional view of the utility model

In the figure, 1-pointer, 2-scale interval, 3-warning light, 4-power cord, 5-switch button, 6-housing, 7-jack area, 8-chip, 9-ammeter.

Detailed ways

In the first embodiment shown in Fig. 1 and Fig. 2, a plug-in strip with overload protection function is characterized in that it is composed of a shell, an ammeter, a chip, a socket area, a button switch, and a warning light; The shell is square, with a power cord on the upper end, a socket area, a button switch, and a warning light on the surface, and an ammeter and a chip inside; the ammeter is provided with pointers and scale intervals.

In the second embodiment shown in Figures 1 and 2, the power cord is used to connect the power supply so that the plug-in strip can work normally; the ammeter is connected to the chip and the warning light through wires, and the ammeter measures the circuit current value, when the pointer degree of the ammeter reaches the maximum value, the measured signal will be sent to the warning light through the chip, and the warning will send out a light alarm; the jack area can be connected to different electrical appliances or other sockets to facilitate people Use; the button switch is used to control the opening or closing of the circuit. When the button switch is pressed, the circuit is in a closed state, and when the button switch is pressed again, the circuit is disconnected.

In the third embodiment shown in Figure 2, the measured maximum value of the ammeter is equal to the maximum current value borne by the power line, that is, the current value measured by the ammeter is the operating current of the power line; the pointer and scale The intervals correspond to each other, and the pointer can move left and right in the scale interval. When the current measures a value, the pointer will point to a certain value in the scale interval. This value is the current value measured by the ammeter.

When using the utility model, first, connect the power supply through the power cord, then press the button switch, the whole circuit is turned on, and when the current value measured by the ammeter reaches the maximum value, the warning light will alarm and short circuit the circuit to prevent unsafe accidents occur.
