At present; the common wiring of family expenses; the rubber layer that only has copper cash and be wrapped in outside copper cash forms; in use; due to aging circuit or household electrical appliance break down; often can there is because opening circuit the phenomenon that plug catches fire; although opening circuit in a flash; the circuit breaker meeting automatic shutdown circuit of family, still, the flare that the high temperature that plug produced in the moment of opening circuit causes; can conduct by the copper cash on electric wire or rubber; the ignite inflammable articles of periphery, even missing of ignition, softening electric wire also can pass high temperature.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of fire-retardant plug, can prevent from being arranged on the electric wire in plug, catches fire or generates heat because of short circuit, makes flare or high temperature pass out and cause the accident.
For achieving the above object, the utility model provides following technical scheme: a kind of fire-retardant plug, comprise plug casing, net tail body and be located at the wire guide at net tail body center, on described plug casing, comprise the through wires hole for net tail body is installed, described net tail body comprises head, protect line portion and afterbody, on described four sides protecting line portion, be respectively equipped with two groups of open slots and two groups of grooves, on the dual-side edge of described open slot, be provided with opening, described groove and the corresponding setting one by one of transverse opening groove, on the hole wall of described wire guide, offer the first cannelure, in described the first cannelure, be filled with expanding flame-proof material.
By adopting technique scheme, on the hole wall of wire guide, offer the first cannelure, and be filled with expanding flame-proof material in the first cannelure, can utilize expanding flame-proof material, run into plug because of short circuit catch fire or in a large number heating, when the outer rubber layer of wire catches fire or melts, expanding flame-proof material runs into high temperature self-expansion, thereby spreading of blocking-up flare, because present household electrical appliance all can have the protection of circuit breaker, short circuit substantially all only exists in a flash, therefore, although the wire of heating still can transmit by copper cash, but intercept the rubber layer outside electric wire, can play the effect of buffering, can make on the one hand copper cash generating heat to cooling procedure, can be not exposed too early, on the other hand, delay the thawing of the outer rubber layer of electric wire.
The utility model is further set to: described the first cannelure comprises bottom surface and two sides, between described two sides and expanding flame-proof material, is equipped with refractory metal sheet.
By adopting technique scheme, refractory metal sheet is set, prevent that expanding flame-proof material is in the time expanding, expanding flame-proof material expands along the axis direction of wire guide, thereby cause losing expansion, the application of force of radial direction, the described flame retardant effect that has ensured expanding flame-proof material in the first cannelure that arranges.
The utility model is further set to: the longitudinal section of described the first cannelure is isosceles trapezoid, and the thickness of described the first cannelure is by successively decreasing to self center position outward.
By adopting technique scheme, can be at the component that ensures expanding flame-proof material in the first cannelure, outside guarantee flame retardant effect, reduce expanding flame-proof material in the time expanding, the width of outlet, thereby application of force when expanding flame-proof material is expanded is more concentrated, more effectively intercept the outer rubber layer of electric wire, result of use is better.
The utility model is further set to: in described wire guide, establish along the axis direction of self and be provided with successively some groups of the first cannelures, refractory metal sheet and expanding flame-proof material, between described each the first cannelure, be also provided with the second cannelure, between described each the second cannelure, be provided with hydro-expansive rubber.
By adopting technique scheme, some groups of the first cannelures are set, refractory metal sheet and expanding flame-proof material, can strengthen the protection to electric wire, in addition, the second cannelure is set, and in the second cannelure, hydro-expansive rubber is set, make the upper net tail of described plug also there is waterproof effect, prevent that attaching plug is in the time of improper use, meet water, when there being water to infiltrate from net tail afterbody, in approach the second cannelure, be arranged on the just imbibition of hydro-expansive rubber in the second cannelure, tightly wrap electric wire, thereby prevent and continue toward plug inside infiltration.
