Abstract
The utility model relates to a power-limiting socket comprising a socket; a power-limiting device is internally provided with a joint 1, a joint 2 and a joint 3; a resistance wire is connected between the joint 1 and the joint 2; a fixed shaft is arranged at the middle of the power-limiting device and fixed with an elastic rigid piece; two ends of the elastic rigid piece are provided with contacts which are respectively contacted with the joint 2 and the joint 3; and the power-limiting device is connected on a zero line or a live line of the socket in series by the joint 1 and the joint 3. The power-limiting socket has the beneficial effects that: 1. safety hidden troubles can be completely eradicated, and the use of electrical products with high power is restricted; 2. electrical appliances with low power are exchanged back after broken circuit, and the power-limiting socket can be used normally without additional operations; and 3. the power-limiting socket is simple and practical, and has convenient carrying.
Description
Technical field
The utility model relates to a kind of socket, especially a kind of socket of rationing the power supply.
Background technology
Electricity-limiter (as air switch) commonly used need be contained in the circuit in advance, if make electrical appliance in the occasion of not adorning electricity-limiter, makes the circuit excess load easily, use immersion heater simultaneously as a lot of people in the dormitory, high-power electric appliances such as electromagnetic stove are easy to make circuit burnout, even cause fire.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of socket of rationing the power supply that the device of rationing the power supply has security performance that carries is provided.
The utility model solves the technical scheme that its technical problem adopts: this socket of rationing the power supply comprises socket, be provided with joint one, joint two and joint three in the electricity-limiter, be connected with resistance wire between joint one and the joint two, be provided with fixedly fixed axis in the middle of the electricity-limiter, fixedly be fixed with the firm sheet of elasticity on the fixed axis, the firm sheet of elasticity two ends are provided with the contact, and two contacts contact with joint three with joint two respectively, and electricity-limiter is connected on the zero line or live wire of socket by joint one and joint three.
As preferably, described fixedly fixed axis has cannelure on the limit, and the firm sheet of elasticity is stuck on the groove.
The effect that the utility model is useful is: one, stop potential safety hazard, the use of high-power electric equipment products is limited; Two, after opening circuit, gain lower powered electrical equipment, need not operation bidirectional and just can use as usual; Three, simple and easy practicality is easy to carry.
Description of drawings
Fig. 1 is the circuit diagram of the utility model embodiment 1;
Fig. 2 is the structural representation of electricity-limiter;
Fig. 3 is the user mode figure of electricity-limiter and the firm sheet of elasticity;
Fig. 4 is the rearview of the firm sheet of elasticity;
Description of reference numerals: socket 1, electricity-limiter 2, joint one 2-1, joint two 2-2, joint three 2-3, the firm sheet 3 of elasticity, electric shock 3-1, resistance wire 4, fixedly fixed axis 5.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment 1: as Fig. 2, electricity-limiter 2 has three joints, be connected with resistance wire 4 between its center tap one 2-1 and joint two 2-2, electricity-limiter 2 is connected on the zero line of socket 1 by joint one 2-1 and joint three 2-3, be provided with fixedly fixed axis 5 in the middle of the electricity-limiter 2, the firm sheet 3 of elasticity is stuck on the cannelure at fixing fixed axis 5 edges and fixes; As Fig. 4, there is contact 3-1 at the firm sheet of elasticity 3 two ends, contact with joint three 2-3 with joint two 2-2 respectively.
When on socket 1, using high-power electrical equipment, in case the electric current that passes through surpasses the rated power of resistance wire 4, resistance wire 4 will generate heat, and conducts heat to the firm sheet 3 of elasticity, the firm sheet 3 of elasticity is owing to be fixed on the fixed axis 5, in case the meeting perk of expanded by heating two ends, contact 3-1 just leaves tie point, opens circuit so form, reach the purpose of rationing the power supply. after temperature falls after rise, the firm sheet 3 of elasticity restores to the original state again, and contact 3-1 is connected with tie point again, recovers path.
During production, can adopt the resistance wire of different model, to reach the requirement that different capacity electrical equipment is limited.
Embodiment 2: electricity-limiter 2 is connected on the live wire of socket 1 by joint one 2-1 and joint three 2-3.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
