Problems solved by technology

[0003] The indicator light installed inside the fuse is often connected with the electrode piece, the replacement procedure of the indicator light is cumbersome, and the connection effect between the replaced indicator light and the electrode piece is poor; the indicator light is installed in the fuse, and the indicator light During operation, the light transmitted by it lacks adjustment, which is not conducive to adjusting the brightness of the external environment and reduces the visibility of the operator to the light of the indicator light; The pre-storage of the main body still needs to be picked up in the external area, increasing the replacement time

Embodiment 1

[0033] see figure 1 and figure 2, a fuse of the present invention that is easy to replace the indicator light, the main body 1, the connecting hole 2, the guide reset assembly 3, the separation and labor-saving assembly 4, the second replacement assembly 5, the spring guide piece 6, the fuse body 7, the electrode piece 8 and the indicator light 9, the upper and lower ends of the main body 1 are provided with connecting holes 2, the upper and lower ends of the main body 1 are provided with spring guide pieces 6, and the spring guide pieces 6 at the upper and lower ends of the main body 1 are in contact with the upper and lower ends of the fuse main body 7, The side of the spring guide piece 6 is connected with an electrode piece 8 , and the guide reset assembly 3 is slidably connected with the left end of the main body 1 .

[0034] see image 3 , a fuse of the present invention that is easy to replace the indicator light, the guide reset assembly 3 includes an auxiliary matc...

Embodiment 2

[0040] For a fuse of the present invention that is easy to replace the indicator light, the distance between the top side surface of the force clamping plate 56 and the top surface of the storage groove 57 is equal to the height of the fuse main body 7, which is convenient for the replacement of the fuse main body 7, so that the original The fuse main body 7 moves to the right end and falls down to the top of the force clamping plate 56 at the upper end of the storage slot 57, so that the fuse main body 7 in the reserved slot 58 can be dropped down to the inside of the guide plate 54, and Contact with the top of the original fuse body 7 can make the replaced fuse body 7 in the position of the original fuse body 7 , the lower end of the cutting plate 48 is sharp, and the bottom frame 41 is in the shape of a loop.

[0041] The present invention provides a kind of fuse which is convenient to replace the indicator light through improvement, and its working principle is as follows; ...

Abstract

The invention discloses a fuse which is easy to replace an indicator light, which includes a main body and a guide reset assembly. By arranging the guide reset assembly at the front end of the main body, a thrust can be applied inward to a force engaging plate and an inner frame can be indirectly driven to the outside end. Move, easy to replace the indicator light quickly, and can release the pressure on the force engaging plate, guide the return spring, and automatically drive the inner frame and the indicator light to move to the inside of the auxiliary matching limit slot, and guide the return spring and apply part of the The thrust is provided to the indicator light, which improves the stability and tightness of the connection between the indicator light and the electrode sheet; by setting the first replacement component at the upper end of the inner frame, the photosensitive sensor can detect the intensity of the light in the surrounding space, roll up the meshing wheel and cooperate with the winding up The retracting area on the meshing wheel drives the concave lens and the convex lens to adjust the position through the traction rope, and when the light intensity is weak, the concave lens moves down and the convex lens moves up, so that when the indicator light is on, the convex lens can make the light transmitted by the indicator light gather in Together.

Description

technical field [0001] The invention relates to the related field of fuses, in particular to a fuse which is convenient to replace an indicator light. Background technique [0002] Fuse (fuse) refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the heat generated by itself after the current exceeds the specified value for a period of time. Melt the melt to disconnect the circuit; a current protector made of this principle, the fuse is widely used in high and low voltage power distribution systems and control systems and electrical equipment as protection against short circuits and overcurrents It is one of the most commonly used protection devices. [0003] The indicator light installed inside the fuse is often connected and in contact with the electrode sheet. The replacement steps for the indicator light are complicated, and the connection eff...
