Abstract
The utility model relates to a power plug with a replaceable fuse, and aims to provide a power plug with a replaceable fuse, which enables electrical equipment to own 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 lines to have the insulation with one another. The utility mode is characterized in that the saddle comprises an inner bracket, an inner bracket cover, a fuse cover and a casing; the pins, the led-outlet lines and a fuse holder(or called fuse clip) are mounted in the inner bracket; one end of the fuse holder is connected with an internal end of one of the pins and the other end is connected with one of the led-outlet lines; a fuse is arranged inside the fuse holder; the inner bracket cover is matched with and covered on the inner bracket; an opening is formed on the inner bracket cover and matched with the fuse cover; the fuse cover is covered on the opening of the inner bracket cover; and the casing enwraps the inner bracket and leads the inner bracket to be exposed out of the casing.
Description
Technical field
The utility model relates to a kind of attaching plug, especially a kind of attaching plug with replaceable fuse tube.
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 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." with the attaching plug of non-disconnectable protective tube " patent of applicant application provides a kind of attaching plug with protective tube, this attaching plug has the protective tube that is suitable for each self-capacity, electrical appliance is played 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.But the protective tube in this attaching plug can not be changed, and can only disposablely use, and this is its shortcoming.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model is to provide a kind of attaching plug of the band replaceable fuse tube that each electrical appliance is had be suitable for each self-capacity protective tube.
The technical scheme that its technical problem that solves the utility model adopts is: an internal frame is arranged in insulation crust, fuse base is arranged in the internal frame, insert protective tube in the fuse base.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 circuit and insulate, it is characterized in that: described bearing includes internal frame, the internal frame lid, protective tube lid and shell, pin is installed in the internal frame, lead-out wire and fuse base (or claiming Insulating tube clip), the inside end of a pin of one termination of this fuse base, lead-out wire of another termination, one protective tube is arranged in the fuse base, the internal frame lid matches with internal frame and is placed on the internal frame, and internal frame has covered an opening, and this opening and protective tube lid match, protective tube is placed on the internal frame cover gab, and shell parcel internal frame also makes the internal frame lid expose shell.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, playing security insurance effect and protective tube better can change easily, checks short trouble and can not influence the operate as normal of other electrical appliances when short circuit line keeped in repair.Simple in structure, easy to manufacture.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an internal frame structural representation of the present utility model.
Fig. 3 is an internal frame lid schematic diagram of the present utility model.
Fig. 4 is a protective tube lid schematic diagram of the present utility model.
Fig. 5 is internal frame lid of the present utility model and protective tube lid assembling back schematic diagram.
Among the figure: 1 be pin, 2 for pin, 3 for fuse base, 4 for protective tube, 5 for internal frame, 6 for lead-out wire, 7 for lead-out wire, 8 for shell, 9 for internal frame lid, 10 be that protective tube covers; 91 is the internal frame cover gab.
Embodiment
Referring to accompanying drawing, the utility model includes pin, bearing, lead-out wire, pin has an end in bearing, the other end is outside bearing, it is characterized in that: described bearing includes internal frame 5, internal frame lid 9, protective tube lid 10 and shell 8, pin 1 is installed in the internal frame 5,2 and lead-out wire 6,7, and a fuse base 3 is arranged in the internal frame 5, the inside end of a pin 1 of one termination of this fuse base 3, lead-out wire 7 of another termination of fuse base 3, one protective tube 4 is arranged in the fuse base 3, internal frame lid 9 matches with internal frame 5 and is placed on the internal frame 5, on the internal frame lid 9 opening 91 is arranged, this opening 91 matches with protective tube lid 10, and protective tube lid 10 is placed on this opening 91, and shell 8 parcel internal frames 5 also make protective tube lid 10 expose shell 8.When the fire that can distinguish pin, ground wire (for example pin 2 is ground wire for live wire, pin 1), live wire pin 2 inside end on the termination plug of fuse base 3, the other end of the fuse base 3 line lead-out wire 7 of starting to exchange fire.Pin 1 and pin 2 play and the supply socket interconnect function; protective tube 4 electrifier overcurrent protections, 6,7 of lead-out wires are carried the function of current, 3 of fuse bases fixedly protective tube 4 and with live wire conductor interconnect function; internal frame 5 works each parts effect of fixing, so that connect injection mo(u)lding.
In a non-limiting examples of the present utility model, protective tube lid 10 is pushing covers, pushes open forward and can change protective tube, can't push the protective tube lid when the charged work of plug open, can push the protective tube lid open after must breaking away from power supply, to guarantee user security.
When injection mo(u)lding, each assembly and internal frame 5 are fused, guarantee connection firmly, good reliability except that other place's injection moulding of fuse base part pours into to enrich.
