Description

一种安全插排a safety socket

技术领域technical field

本实用新型属于安全插座技术领域,具体涉及一种安全插排。The utility model belongs to the technical field of safety sockets, in particular to a safety socket.

背景技术Background technique

目前,随着生活水平的提高,家用电器的使用也越来越多,插排也成为生活中必不可少的器件。插排也叫排插、插线板或拖线板等,就是移动的插座,其专业术语是电源转换器。插排是有插孔或凹洞的母接头,用来让有棒状或铜板状突出的电源插头插入,以将电力经插头传导到家用电器。如果使用不当会引起人身电击和电气火灾事故,带来重大损失。目前的插排还有一些缺点:首先,由于插排是连接用家用电器与电源的中间连接器,电冰箱、空调和洗衣机等家用电器,仅是按下家用电器上的关闭按钮是不能完全关闭电源的,家用电器都处于待机的状态,不仅耗电还影响家用电器本身的使用寿命,且随着家用电器的增多,待机消耗的能源迅速增长,造成了电能的严重浪费。当然,在插排使用的过程中,如果插排中的电流过大或电压过大,常用插排没有保护装置,不能及时切断插排,这就容易引发安全事故。其次,随着科学技术的发展,利用USB接口充电的电子产品越来越多,比如手机、平板电脑、移动电源、MP5和数码相机等,而现有的插排必须与充电转换插头配合才可以完成充电,给用户带来了不便。另外,插排作为主要的电器电源转换装置,现有的插排内部一般未安装散热装置,很容易长时间使用后过热而发生故障或被烧坏,从而存在安全隐患,同时也减少了插排的使用寿命。最后,目前市场上出现智能插排,包括定时器插排和遥控插排等,定时器插排具有定时功能,虽然能够控制电器在特定的时间段工作,在一定的程序上减少了空闲时间的能源浪费,但是如果电器的使用时间不固定,需要重新设定,使用不方便;另外遥控插排虽然可以远距离控制,但是其需要配备专用的遥控器,成本较高,不能满足大众的需求。因此,现如今缺少一种结构简单、成本低、设计合理、易操作的安全插排,避免电器待机耗能,增加插排使用的安全性和便捷性。At present, with the improvement of living standards, more and more household appliances are used, and sockets have become an indispensable device in life. The socket is also called a socket, a power strip or a power strip, etc. It is a mobile socket, and its technical term is a power converter. The plug strip is a female connector with a jack or a concave hole, which is used to insert a rod-shaped or copper plate-shaped protruding power plug to conduct electricity to household appliances through the plug. Improper use can cause personal electric shock and electrical fire accidents, resulting in heavy losses. The current plug-in strip also has some disadvantages: first, because the plug-in strip is an intermediate connector connecting the household appliances and the power supply, household appliances such as refrigerators, air conditioners and washing machines cannot be completely closed only by pressing the shutdown button on the household appliances. The power supply and household appliances are in standby state, which not only consumes power but also affects the service life of the household appliances themselves, and with the increase of household appliances, the energy consumed in standby increases rapidly, resulting in a serious waste of electric energy. Of course, during the use of the plug-in strip, if the current or voltage in the plug-in strip is too large, the commonly used plug-in strip has no protection device, and the plug-in strip cannot be cut off in time, which is likely to cause a safety accident. Secondly, with the development of science and technology, there are more and more electronic products that use USB ports to charge, such as mobile phones, tablet computers, mobile power supplies, MP5 and digital cameras, etc., and the existing power strips must be matched with charging conversion plugs The charging is completed, which brings inconvenience to the user. In addition, the plug-in strip is the main electrical power conversion device. The existing plug-in strip is generally not installed with a heat sink, and it is easy to overheat after long-term use and cause failure or burnout. service life. Finally, there are smart sockets on the market, including timer sockets and remote control sockets. The timer socket has a timing function. Although it can control electrical appliances to work in a specific period of time, it reduces the idle time in a certain program. Energy is wasted, but if the use time of the electrical appliance is not fixed, it needs to be reset, which is inconvenient to use; in addition, although the remote control strip can be controlled from a long distance, it needs to be equipped with a dedicated remote control, which is expensive and cannot meet the needs of the public. Therefore, there is a lack of a safe plug-in strip with simple structure, low cost, reasonable design, and easy operation, which can avoid energy consumption of electrical appliances in standby and increase the safety and convenience of the plug-in strip.
