Abstract

The utility model relates to a high voltage fuse which comprises a terminal jack, a spring, an insulation bottom cover, a base a fuse, a crimp film, a high voltage wire and a groove. Wherein one end of the terminal jack is welding connected with the spring. The other end of the terminal jack is embedded into an insulation base. The other end of the spring is pressed and connected with one end of the fuse by the crimp film. The other end of the fuse is welding connected with one end of the high voltage wire. The high voltage wire is embedded in the groove. The high voltage fuse of the utility model has the advantages of simple structure, low cost and small bulk, which is suitable for various types of microwave oven and high voltage equipment.

Description

High-tension fuse

Technical field

The utility model relates to-kind of fuse, and particularly a kind of high-tension fuse belongs to electric component.

Background technology

At present microwave oven and-all be to adopt traditional high-voltage fuse in the high tension loop of a little electric equipments, this kind high-voltage fuse is by two copper blocks, glass tube, compositions such as spring and fuse.This kind fuse volume is bigger, and high voltage performance is relatively poor, and mechanism is complicated, and also inconvenience is installed.To this, relevant industry is constantly developed innovation, manufactures experimently out some new products, is ZL03210260.7-micro-wave oven high-voltage fuse-link assembly etc. as China Patent No..It is mainly by spring, the insulation loam cake, bottom, two compressing pieces, two terminal sockets, compositions such as fuse, and fuse, terminal interface, high-voltage conducting wires after the compressing piece crimping again clasp joint connect.Though this product has been done very big improvement, volume is also little, and can be made into various geometries, and applicability is stronger, and structure is still complicated.

Summary of the invention

It is low that the purpose of this utility model provides a kind of cost, easy for installation, the high-tension fuse of good pressure-resistant performance.

The utility model is achieved in that it comprises two terminal sockets, spring, the insulation bottom, insulator foot, compressing piece, fuse, high-voltage conducting wires, sheath, also comprise a groove, wherein a described terminal socket-end and the welding of an end of described spring, its other end is embedded in the described insulator foot, spring in addition-end of end and described fuse is with described compressing piece crimping, one end of the other end of fuse and described high-voltage conducting wires is to be welded to connect, the other end of high-voltage conducting wires and described another terminal socket join, and described sheath is to be sleeved on this terminal socket, and high-voltage conducting wires is embedded in the described groove.

The diameter of described groove is less than the diameter of described high-voltage conducting wires, and described insulation bottom, insulator foot can be made into U type L type shape.

High-tension fuse of the present utility model so it is simple in structure, has reduced cost owing to adopt said structure, and good pressure-resistant performance is applicable to various model microwave ovens and high voltage electric equipment.

Description of drawings

The utility model is described in further detail for embodiment below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a bottom of the present utility model, and base is the structural representation of L type.

Fig. 1 is in 2: 1. terminal socket 2. springs 3. bottoms 4. bases 5. compressing pieces 6. fuses 7. grooves 8. high-voltage conducting wires 9. terminal sockets 10. sheaths

Embodiment

As shown in Figure 1, the one end welding of one end of the terminal socket 1 that will be processed into by required size and spring 2, between an end of the other end of spring 2 and fuse 6, be connected with compressing piece 5 crimping, the other end of terminal socket 1 is embedded in the insulator foot 4, the other end of fuse 6 end direct and high-voltage conducting wires 8 welds, the other end of high-voltage conducting wires 8 is connected to terminal socket 9, then high-voltage conducting wires 8 is embedded in the groove 7 tightly, groove 7 is to be compressed on an end of insulator foot 4 and is one-shot forming that the diameter that the diameter of groove 7 is slightly less than high-voltage conducting wires 8 gets final product.Sheath 10 is sleeved on the terminal socket 9, installs easily like this, and bottom 3 fastenings of will insulating at last get final product on insulator foot 4.Insulation bottom 3 of the present utility model, the shape of insulator foot 4, big I is by required processing, and in the present embodiment, as the insulation bottom 3 among Fig. 1, insulator foot 4 is processed into the U type, also can be processed into the L type, as shown in Figure 2.

Because the advantages such as the utility model high-tension fuse high voltage performance is good, and volume is little are so work as microwave When stove or the normal operation of electrical equipment mesohigh loop, high-tension fuse can keep the loop normally unimpeded; When breaking down, because of factors such as current overload or electric leakages, this high-tension fuse can cut off in quick-break The loop is played other device of protection and is not damaged. Simultaneously and since high-tension fuse fusing moment, Its inner spring bounces back rapidly again, and the separation of fuse arrives certain distance, thereby makes this assembly Two ends can sustain the above voltage of 8-15KV and not puncture, improved reliability and the safety of whole product The property.
