Abstract
The utility model discloses a temperature control safety plug, comprising a plug body and a plug pin disposed on the plug body, a temperature safety switch and a wiring terminal which are disposed in the plug body. One end of the wiring terminal is provided with an interface for being matched with a power line, and the other end is connected with the plug pin through the temperature safety switch. The temperature control safety plug has a delicate and compact structure, and is provided with the temperature safety switch, thus being capable of effectively preventing fire disasters, and being safe and reliable. When a current exceeds the rated current, a temperature sensing sheet in the temperature safety switch is heated and therefore bends and deforms and warps upwards, enables a movable contact on the temperature sensing sheet to automatically detach from a static contact on a fixed contact piece, and the circuit is cut off, the plug is ensured to be work safely under the rated current, thereby protecting an electrical appliance; and when an external circuit returns to normal, the temperature of the temperature sensing sheet drops and automatically returns to an original shape, enabling the circuit to be conducted again and to be restored to normal operation. The temperature control safety plug is convenient to use, and is particularly suitable for some users who has no knowledge of replacing a protective tube.
Description
Technical field
The utility model relates to plug, and especially a kind of have a temperature protection function, effectively prevents the temperature control safety plug of fire.
Background technology
The known power-line plug of existing market be by two pins directly and power line (being live wire and zero line) link together, injection moulding PVC moulding and generating again, attaching plug includes pin, bearing, lead-out wire.Pin has an end in bearing, to be connected with an end of lead-out wire, and the other end exposes to outside the bearing, is used for injecting supply socket and introduces power supply, and power supply is delivered to electrical appliance through lead-out wire, and bearing makes between each pin insulation and makes charged position and external insulation.In order to guarantee the safety of electricity consumption, operated by rotary motion is useful on the protective tube of overload and short-circuit protection in the circuit.But it still exists shortcoming; When being short-circuited like the electric equipment after the plug or household electrical appliance; To rely on total safety box fusing protective tube on the one hand and protect this short circuit electric equipment or household electrical appliance; Because the protective tube of total safety box breaks off, other normal electric equipments or household electrical appliance can't be used on the other hand, ordinary production and life around the influence.Therefore the plug of prior art brings a lot of inconveniences for people's production and life.
Fail safe when using in order to ensure plug; One Chinese patent application number is 201020292930.6 " new type of plug "; In attaching plug, have the removable protective tube that is suitable for this plug capacity; Electrical appliance is played the security insurance effect better, inspection short trouble and can not influence the operate as normal of other electrical appliances when short circuit line keeped in repair.But after protective tube damages since a lot of electricity consumers do not know should the great protective tube of adapted and often be not equipped with subsequent use protective tube, bring very big inconvenience for the work of changing protective tube, prolonged the down time of electrical equipment.
The utility model content
To the existing above-mentioned deficiency of existing plug, the purpose of the utility model is, provide a kind of simple for structure, easy to use and effectively prevent fire, safe and reliable and the temperature control safety plug.
For realizing above-mentioned purpose, the technical scheme that the utility model provided is:
A kind of temperature control safety plug; It comprises a header body and is arranged on the pin on this header body; It also comprises Temperature protection switch and the binding post that is arranged in the said header body; This binding post one end is provided with and is used for and the suitable interface of power line, and the other end is connected with pin through the Temperature protection switch.
Said Temperature protection switch comprises a fixed touching plate, a thermal sensitive piece and a high-temperature insulation pad; The tail end of said fixed touching plate is connected with binding post, and the head end of this fixed touching plate is fixed on the lateral surface of high-temperature insulation pad, and the head end of said thermal sensitive piece is connected with pin; The middle part of this thermal sensitive piece is fixed on the medial surface of high-temperature insulation pad; The tail end of this thermal sensitive piece extends to medium position one side of fixed touching plate, and is provided with a moving contact, and correspondence is provided with the fixed contact suitable with this moving contact on said fixed touching plate.
Said header body comprises that seat and is coated on the shell on the seat in this in one, and this shell is provided with one and lets opening that seat exposes in this, and this opening is provided with can be with the cover plate of its sealing.
The beneficial effect of the utility model is: the utility model structural design is ingenious, compact, is provided with the Temperature protection switch, can effectively prevent fire, safe and reliable; When electric current surpasses rated current; Thermal sensitive piece heated bending distortion in the Temperature protection switch liters of tilting upward, make on it moving contact automatically and the fixed contact on the fixed touching plate be separated the cut-out circuit; Guarantee plug trouble free service under rated current, play the effect of protection electrical equipment; After external circuit recovered normally, the temperature of thermal sensitive piece descends and recovers original form automatically, makes circuit conducting again, recovers operate as normal, and was easy to use, was specially adapted to the user of some no protective tubes replacing knowledge.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
