Background technology
Switch socket is just mounted in the electric switch and socket used on wall, is used for make-and-break contact
Household electrical appliance, can make sometimes in order to attractive in appearance its also have decorate function.Switching has the difference of dual control and single control, and dual control is every
Individual unit binding post more than single control.One lamp can be controlled in room, and referred to as dual control can also be controlled outside room, and dual control is opened
Single control can be worked as by, which closing, uses, but single control switch cannot make dual control.Switch classification, is divided by the Starting mode of switch：Pullswitch,
Rotary switch, tumbler switch, button switch, rocker switch soft-touch controls etc.；Conventional switch is classified by connected mode：Single control is opened
Pass, double control switch, bipolar (two-way) double control switch etc..Socket, switch on wall narrow sense refer to switch, and actually refer to that wall is opened
Close, this big region of wall socket.There is machinery, have intelligent, have flat board, there is seesaw.Socket for computor is also known as network
Socket, network cable socket, Broadband Points, network panel.Network one kind separates from phone, so just there is Telephone computer integrally to insert
Seat；Network another kind separates from cable television, so there is teleputer integral socket.TV socket is also known as TV sockets, TV
Panel, wired socket, air conditioner socket etc..
At present, the switch socket of in the market, security performance is poor, and the things such as hand or iron wire are easily inserted socket by child
Hole, cause electric shock.Do not have to the safeguard measure of socket in itself, any one operating failure of circuit may all influence whole yet
Other electrical equipment used on power network and power network, it is also inconvenient in mounting receptacle, it is dangerous.
Utility model content
The purpose of this utility model is to provide a kind of current protection switch socket using PTC, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of current protection switch using PTC
Socket, including switch socket, switch, jack, fire wire bus, zero line bus and PTC overflow protecting elements, in the switch socket
Portion is provided with dividing plate, and the dividing plate side is provided with jack and USB interface, and the dividing plate opposite side is provided with switch, described to open
Close, jack and USB interface both ends are electrically connected with by branch line with the terminals of fire wire bus and zero line bus and using in parallel
Mode, PTC overflow protecting elements are installed in the fire wire bus and zero line bus.
Preferably, the jack includes three-way jack and two line jacks, and the three-way jack is arranged on the upper of two line jacks
Side.
Preferably, the switch is provided with two, and switchs top and be provided with noctilucence block.
Preferably, switch socket upper end both sides are provided with protective cover by hinge, and described protective cover one end is provided with
Handle.
Preferably, the USB interface is arranged on the downside of jack, and USB interface is provided with two.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model by provided with PTC overflow protecting elements, due to PTC, polarity is not connected on load circuit
In, the quick of PTC resistances increased dramatically, and will effectively limit the operating current in whole loop, is thus effectively protected negative
Load is not burned.
2nd, the utility model is provided with protective cover by switch socket upper end both sides by hinge, can prevent from switching and inserting
Hole is directly touched by child, improves the security used, and USB interface is arranged on the downside of jack, and USB interface is provided with
Two, using the teaching of the invention it is possible to provide USB charges or the function of connection power supply, improves the diversity of function.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of current protection switch socket using PTC,
Including switch socket 1, switch 2, jack 3, fire wire bus 5, zero line bus 6 and PTC overflow protecting elements 7, the switch socket 1
Middle part is provided with dividing plate 11, and the side of dividing plate 11 is provided with jack 3 and USB interface 4, and the opposite side of dividing plate 11 is provided with out
2 are closed, switch 2, jack 3 and the both ends of USB interface 4 pass through terminals 51 of the branch line 8 with fire wire bus 5 and zero line bus 6
