Description

A kind of lightning-arrest socket

One, technical field

The utility model belongs to the household socket technical field, especially relates to a kind of socket that has lightning-arrest function.

Two, background technology

At present; the general structure of the socket of family expenses is more single; majority is the socket aperture that is provided with various ways on socket, in order to protect electrical appliance, generally is provided with independent insurance on socket; prevent the damage of super-high-current to household electrical appliance; though adopted anti-surge circuit on the socket that has at present, because its circuit complexity does not have Presentation Function; cost is higher, is not suitable for family and uses.

Three, summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide a kind of circuit simple, have Presentation Function, easy to use, a lightning-arrest socket that cost is low.

The purpose of this utility model is achieved in that a kind of lightning-arrest socket, is made up of socket, socket, is characterized in being provided with on socket groove, and groove is provided with the recess cover of flexible connection, is provided with lightning circuit in the groove.

In order further to realize the purpose of this utility model, can also be that described lightning circuit is to be connected between phase line L and the center line N at insurance F and piezo-resistance M, the two ends of gas discharge tube G1 are connected between center line N and ground wire G.

In order further to realize the purpose of this utility model, can also be that described lightning circuit is in parallel with piezo-resistance M after diode D, resistance R, the LED series connection, LED is installed in the socket surface.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is to be provided with lightning circuit in the groove on socket, lightning circuit is to be connected between phase line L and the center line N at insurance F and piezo-resistance M, the two ends of gas discharge tube G1 are connected between center line N and ground wire G, circuit is simple, safe and reliable, cost is low, in lightning circuit, be provided with display circuit, display circuit is diode D, resistance R, LED series connection back is in parallel with piezo-resistance M, LED is installed in the socket surface, by the luminous situation of LED, show that whether lightning circuit lost efficacy, and had improved reliability like this.

Four, description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is a kind of electronic-circuit diagram of the utility model lightning circuit.

Fig. 3 is an another kind of structural representation of the present utility model.

Fig. 4 is the another kind of electronic-circuit diagram of the utility model lightning circuit.

Five, specific embodiments

Embodiment 1, a kind of lightning-arrest socket, with reference to Fig. 1, Fig. 2, be to be provided with socket aperture 2 on socket 1, socket 1 is provided with groove 3, and groove 3 is provided with the recess cover 4 of flexible connection, be provided with lightning circuit 6 in the groove 3, lightning circuit 6 is to be connected between phase line L and the center line N at insurance F and piezo-resistance M, and the two ends of gas discharge tube G1 are connected between center line N and ground wire G, and this has constituted a kind of structure of the present utility model.

Embodiment 2, a kind of lightning-arrest socket, with reference to Fig. 3, Fig. 4, be on the basis of embodiment 1, in parallel after diode D, resistance R, the light-emitting diode 5LED series connection in lightning circuit 6 with piezo-resistance M, light-emitting diode 5LED is installed in socket 1 surface, is used to show the operating state of lightning circuit, and other and embodiment 1 are identical.

When using the utility model; insurance F between phase line L and center line N; MOV piezo-resistance M; rectifier cell diode D; the current limiting element resistance R; and LED has constituted surge thus and releases and show the defencive function circuit; wherein; the leadage circuit that M and F form is in high-impedance state under normal operating position; when phase line L has surge to arrive; the M conducting of MOV piezo-resistance and this surge of releasing; guarantee device security; the insurance F piezo-resistance M disengaging electrical network that under the situation of piezo-resistance M inefficacy short circuit, fuse and will release; guarantee not influence the use of follow-up equipment; diode D; resistance R and LED are formed display circuit in order to the display circuit state; lightning protection function is normal during bright lamp; lightning protection function lost efficacy when turning off the light; at this moment; need change the surge leadage circuit that damages; between center line N and ground wire G, installed gas discharge tube G1 additional; it mainly acts on is the surge that absorbs from center line; prevent this surge intrusion rear end power consumption equipment; G1 is in open-circuit condition when no surge; when surge, the G1 conducting.
