The fuse is widely applied to high and low voltage distribution systems, control systems and electric equipment, and is one of the most commonly applied protection devices as a short circuit and overcurrent protector. The fuse is the most common one, and the fuse is an electrical appliance which uses a metal conductor as a fuse body to be connected in series in a circuit, and is fused due to self heating when overload or short-circuit current passes through the fuse body, so that the circuit is broken.
Conventional fuse is bulky, and the structure is complicated to a fuse is only applicable to a machine, and only opens the power supply after fusing and finds that it is broken off just not to have the circular telegram, and is very inconvenient, and more common fuse and casing integrated into one piece just need change whole fuse if damaging, have improved the cost greatly.
The invention content is as follows:
the utility model aims at the not enough of above-mentioned prior art, provide a small and exquisite, easy dismounting of structure, change melt the core convenient and have the novel fuse of pilot lamp. The purpose of the invention is achieved by the following technical scheme: the utility model provides a novel fuse, it is including melting disconnected ware body shell, be equipped with a fuse holder in the body shell, the intermediate position of body is settled through the bolt to the handle that accessible support top set up is 45 degrees angles with the rotatory upwards perk of support, is equipped with fuse holder in the bottom of this support, inside for the rectangular shape cavity of placing the fuse, still be equipped with an indicating device at the top of support, two profile modeling grooves about this internal bottom both sides are equipped with respectively, and this profile modeling groove length equals the length of fuse holder to be equipped with the draw-in groove that is used for blocking fuse holder at the top in profile modeling groove, the bottom both sides in profile modeling groove are equipped with two wiring boards respectively, and this wiring board is connected and is set up in the binding clip of body edge, the binding clip is used for the access of external power source line.
Preferably, the method comprises the following steps: the indicating device is an indicating lamp arranged at the top of the bracket, the indicating lamp is arranged in a lamp groove at the top of the fuse bracket, two contact pieces are respectively arranged at two sides of the middle of the bracket, one contact piece is connected with the anode of the indicating lamp, the other contact piece is connected with the cathode of the indicating lamp through a small resistor, and the two contact pieces are connected to the wiring board.
Preferably, the method comprises the following steps: the wiring clamp is a square connecting block, a wire hole penetrating through the wiring clamp is formed in the middle of the connecting block, a fixing hole is formed in the top of the wiring clamp, the fixing hole is penetrated through a screw to be fixed, a positioning groove is formed in the bottom of the connecting block, the groove is clamped in the edge of the body shell, the wire hole of the wiring clamp is parallel to the edge of the body shell, and protruding clamping blocks used for clamping a wiring board are arranged on two sides of the bottom in the wire hole.
The utility model discloses it is convenient to have the change, convenient to use to can very audio-visual seeing after opening circuit and fused, and safer, the cost of manufacture that has significantly reduced, small and exquisite design can be applicable to more families and small-size shops and use, lets the power consumption safe and reliable more.
