Abstract
The utility model relates to a safe socket with current overload protection, which comprises a socket shell, a zero line, a live line, a spring, an armature, an electromagnetic relay, a fixed coil and a plug, wherein one end of the spring is fixed at the inner side of the socket shell, the other end of the spring is provided with the armature, two sides of the armature are connected with the zero line, the electromagnetic relay is arranged below the armature and connected with the fixed coil through a wire, and the zero line and the live line are connected with the plug on the surface of the socket shell. Compared with the prior art, the safe socket provided by the utility model has the beneficial effects of low cost, simple structure and convenient use; a household appliance can power off automatically without influencing other household appliances when short circuit occurs in the household appliance and the current is overloaded, and power supply can be recovered automatically and operate normally when the current of the household appliance returns to normal, thereby effectively ensuring the safety of electricity utilization, increasing safety measures of current overload protection, better protecting the household appliances, and preventing the electrical appliances from being damaged.
Description
Technical field
The utility model relates to the jack technology field in the electrical equipment facility, particularly a kind of safety socket of preventing over-current protection.
Background technology
In daily life; continuous increase along with household electrical appliance such as computer, TVs; people to the demand of socket also in continuous increase; socket is varied in the market; but the socket that does not have a kind of preventing over-current protection; after some household electrical appliance are long in the operating time; phenomenons such as insulated hull is aging, wearing and tearing can appear; untimely outage causes short circuit easily, if can make electrical equipment burn out; though air switch can play a protective role; but after the outage, other electrical appliance can not have been worked, and must manually air switch be restored.
Summary of the invention
The purpose of this utility model provides a kind of realization outage and automatic recovery of power supply automatically, and has guaranteed the safety socket of Electrical Safety.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of safety socket of preventing over-current protection, comprise jack housing, zero line, live wire, spring, armature, electromagnetic relay, fixed coil and plug, described spring one end is fixed on the jack housing inboard, the spring other end is provided with armature, the armature both sides are connected with zero line, the armature arranged beneath has electromagnetic relay, and electromagnetic relay is connected with fixed coil by lead; Described zero line is connected with the plug on jack housing surface respectively with live wire.
Compared with prior art, the beneficial effects of the utility model are:
A kind of safety socket of preventing over-current protection; have cost characteristics low, simple in structure, easy to use, short circuit occurs and during current overload, household electrical appliance can cut off the power supply automatically at household electrical appliance; do not influence other household electrical appliance; treat the household electrical appliance electric current recover normal after, can automatic recovery of power supply, operate as normal; effectively guaranteed Electrical Safety; increased the safety measure of overcurrent protection, and protected household electrical appliance better, prevented that household electrical appliance are impaired.
Description of drawings
Fig. 1 is structure chart of the present utility model.
1-jack housing, 2-zero line, 3-live wire, 4-spring, 5-armature, 6-electromagnetic relay, 7-lead, 8-fixed coil, 9-plug
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
As shown in Figure 1, the utility model is a kind of safety socket of preventing over-current protection, comprise jack housing 1, zero line 2, live wire 3, spring 4, armature 5, electromagnetic relay 6, fixed coil 8 and plug 9, described spring 4 one ends are fixed on jack housing 1 inboard, spring 4 other ends are provided with armature 5, armature 5 both sides are connected with zero line 2, and armature 5 arranged beneath have electromagnetic relay 6, and electromagnetic relay 6 is connected with fixed coil 8 by lead 7; Described zero line 2 is connected with the plug 9 on jack housing 1 surface respectively with live wire 3.
When using the utility model, when household electrical appliance ran well, electric current was in normal range (NR), and the magnetic of electromagnetic relay 6 generations at this moment is not enough to attract armature 5, and armature 5 is in connection status with zero line 2, and circuit system is connected, and socket is normally connected use; When electric current increased suddenly because of short circuit or other reason, it is big that induced electromotive force becomes, and the magnetic of electromagnetic relay 6 strengthens, and armature 5 is adsorbed onto on electromagnetic relay 6 surfaces, make zero line 2 be in off state, thereby realized that household electrical appliance cut off the power supply automatically, do not influence other household electrical appliance; After treating that this household electrical appliance electric current recovers normally, the magnetic field that electromagnetic relay 6 produces reduces, because the elastic reaction of spring 4 makes armature 5 return to the state that links together with zero line 2, thereby realized the household electrical appliance automatic recovery of power supply.
Above-mentioned plug 9 can be two hole plugs or three hole plugs.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
