Abstract
The utility model discloses a power plug with an undetachable fuse, and aims to provide a power plug which enables electrical equipment to possess volume-adaptable fuses and have no jamming among one another. The power plug comprises pins, a saddle and led-out lines, wherein one end of each pin is arranged in the saddle, the other end is arranged outside the saddle, and the saddle enables the pins to have the insulation with one another, and cause an electrified part to have the insulation with the outside. The utility mode is characterized in that the saddle comprises an inner bracket, an inner bracket cover and an outer colloid; the pins and the led-outlet lines are mounted in the inner bracket; a fuse is arranged in the inner bracket; one end of the fuse is connected with the inner end of one of the pins, and the other end of the fuse is connected with one of the led-outlet lines; the inner bracket cover is arranged on the inner bracket; and the outer colloid envelops the inner bracket and the inner bracket cover.
Description
Technical field
The utility model relates to a kind of attaching plug, especially a kind of attaching plug with non-disconnectable protective tube.
Background technology
Attaching plug includes pin, bearing, lead-out wire, pin has an end to be connected with an end of lead-out wire in bearing, the other end of pin exposes to outside the bearing, be used for injecting supply socket and introduce power supply, power supply is delivered to electrical appliance by 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.Its protective tube of the power circuit of prior art is arranged on socket or the mains switch, but supply socket or mains switch are often wanted the electrical appliance of a plurality of electrical appliances of traction or different capacity, for making all electrical appliances can both operate as normal, protective tube on supply socket or the mains switch just must have enough capacity, but capacity is just too big concerning single electrical appliance like this, lose safety effect, even can cause fire.Socket for a plurality of electrical appliances, all electrical appliances all can not be worked when an electrical appliance breaks down protective tube fusing, break down but also can not differentiate that electrical appliance soon. when changing protective tube, all electrical appliances are quit work.
Summary of the invention
The purpose of this utility model is to provide a kind of protective tube and non-interfering attaching plug that each electrical appliance is had be suitable for each self-capacity.
The technical scheme that its technical problem that solves the utility model adopts is: the protective tube that the capacitance size with the electrical appliance that uses this plug is complementary is installed at live wire pin place on plug, connects the power supply lead wire live wire end of electrical appliance again by protective tube.Be that the utility model includes pin, bearing, lead-out wire, pin has an end in bearing, the other end is outside bearing, bearing makes between each pin insulation and makes charged position and external insulation, it is characterized in that: described bearing includes inner support, inner support lid and outer colloid, pin and lead-out wire are installed in the inner support, and a protective tube is arranged in the inner support, the inside end of a pin of one termination of this protective tube, lead-out wire of another termination, inner support is placed on the inner support, outer colloid parcel inner support and inner support lid.When the fire that can distinguish pin, ground wire, the live wire pin inside end on the termination plug of protective tube, the other end line lead-out wire of starting to exchange fire.
The beneficial effects of the utility model are: can pack into to each electrical appliance and be suitable for the protective tube of its capacity, play the security insurance effect better, check short trouble and can not influence the operate as normal of other electrical appliances when short circuit line keeped in repair.And it is simple in structure, easy to manufacture.
