Fifteen-hole power socket

Abstract

The invention discloses a fifteen-hole power socket. The fifteen-hole power socket comprises a power line, a housing, a lightening protection module and a fifteen-hole power output socket. The lightening protection module and the fifteen-hole power output socket are assembled on the panel of the housing; the power line is connected with the lightening protection module in the housing and the output pin of the power output socket, and the lightning protection module comprises pressure-sensitive resistors, a gas discharge tube, an LED luminous tube, a current-limiting resistor, a PCB, a temperature fuse, phosphor copper spring sheets and low-temperature solder tin points; the pressure-sensitive resistors and the gas discharge tube form a lightening protection loop; the phosphor copper spring sheets, the low-temperature solder tin points and the temperature fuse form a dual release and are connected in series with the lightening protection loop; the lightening protection module is connected in parallel among a live wire, a zero wire and a ground wire of the power line; the dual release opens the lightening protection loop when the pressure-sensitive resistors are heated; and the LED luminous tube is connected in series with the current-limiting resistor and then is connected with the sides of the pressure-sensitive resistors at the two low-temperature solder tin points. The fifteen-hole power socket can perform lightening protection on external equipment and can also protect the safety of a lightening protection device itself.

Description

technical field [0001] The invention relates to the field of lightning protection and power sockets, in particular to a fifteen-hole power socket. Background technique [0002] With the advancement of society and the promotion of science and technology, people's production activities and daily life are increasingly inseparable from various electrical appliances and communication equipment, so a large number of power sockets in various forms will be used. Most of the power sockets for ordinary civilian use are mainly of plastic shell structure. In the field of industrial power sockets, a standard metal shell structure power distributor has been introduced in recent years, which is suitable for power supply of various electric power, communication and instrument cabinets. As an electrical device to prevent induced lightning shock and surge interference, the lightning arrester has been gradually popularized and used. There are already many types of products that combine lightn...

AI Technical Summary

Problems solved by technology

In the power socket with lightning protection function in the industry, a fuse tube or a thermal fuse tube is generally inserted in series between the piezoresistive element and the power line, but the small fuse tube that can be installed in the power socket shell generally has a small current carrying capacity. It is often necessary to fuse when the lightning protection discharges current; and if a thermal fuse is used, the fuse reaction is slow, and it may not be able to quickly separate the faulty lightning protection component from the power line, so the reliability of lightning protection and the safety of use are not comprehensive enough. , can not take into account
