Abstract

The utility model discloses a fuse tube, consisting of a fusible body, electric conducting terminals and an insulation shell. The insulation shell is a closed type, which covers at the outside of the fusible body; two electric conducting terminals extend into the insulation shell; the two ends of the fusible body are respectively welded and fixed with an electric conducting terminal. Wherein, the fusible body either can consist of more than one metal wire, or can consist of more than one metal wire and a bearing body which can be a resistance or an insulator. The electric conducting terminals can be leads, such as tinned wires, or other electric conductors. The utility model has the advantages of easy processing and production, good fixing effect, and low product cost as well as no influence to the use performance.

Description

A kind of cartridge fuse

Technical field

The utility model relates to a kind of cartridge fuse, belongs to the technical field of circuit emergency protective device.

Background technology

In the prior art, the structure of cartridge fuse is in the insulated tube 2 ' (porcelain tube or glass tube) in open at both ends fusable links 1 ' (wire) to be set, and by copper cap 3 ' fusable links 1 ' is fixedly mounted in insulated tube 2 ' roughly as shown in Figure 1.Because fusable links 1 ' is to be welded on the copper cap 3 ', relend and help copper cap 3 ' and insulated tube 2 ' to fix to cooperate and be fixed on the insulated tube 2 ', so, not only have certain difficulty in the processing and manufacturing, fixed effect is relatively poor, influences serviceability, and, copper cap 3 ' volume is bigger, and the copper material price is more expensive, causes product cost higher.

Summary of the invention

The purpose of this utility model is to provide a kind of cartridge fuse, and its processing and manufacturing is easy, and fixed effect is good, do not influence serviceability, and product cost is low.

Solution of the present utility model is:

A kind of cartridge fuse is made up of fusable links, conducting terminal and insulation crust, and it is closed that insulation crust is, and insulation crust covers on outside the fusable links, and two conducting terminals stretch in the insulation crust, and the two ends of fusable links are welded respectively and fixed a conducting terminal.

Wherein, fusable links can be made up of the wire more than, also can be made up of wire more than one and supporting mass; Supporting mass can be a resistance, also can be insulator.

Conducting terminal can be a lead, as tinned wird, also can be other electric conductors such as sheet metal.

After adopting said structure, the utility model is because fusable links is directly to be welded between two conducting terminals that stretch in the insulation crust, by stretching into two conducting terminals in the insulation crust fusable links is fixedly mounted in insulation crust, replaced in the prior art fixed form that fixes by copper cap and insulated tube, so processing and manufacturing is easy, good fixing effect does not influence serviceability, and avoided using the bigger copper cap of volume, product cost is reduced.

Fig. 5 is embodiment four structural representations of the utility model cartridge fuse.

Embodiment

Consulting shown in Figure 2ly, is the embodiment one of a kind of cartridge fuse of the utility model, is made up of fusable links, conducting terminal 2 and insulation crust.

Wherein, insulation crust is cooperated by the housing 3 of the uncovered end of end sealing and end cap 31 and forms enclosed construction, and the blind end of housing 3 is offered jack 32, and end cap 31 covers the opening end that is located at housing 3, offers jack 33 on the end cap 31.

Two conducting terminals 2 are tinned wirds, stretch in the insulation crust from passing

jack

32,33 respectively, and fusable links only is an one metal wire 1 (two or more also can), and the two ends of wire 1 are welded respectively and fixed a conducting terminal 2.

During actual production, the two ends of fusable links wire 1 are welded respectively fix a conducting terminal 2 earlier, again two conducting terminals 2 are passed

jack

32,33 respectively, and end cap 31 is covered the opening end that is located at housing 3, promptly constitute the manufactuerer's output insurance fiber tube.

Seeing also shown in Fig. 3,4, is the embodiment two, three of a kind of cartridge fuse of the utility model again, still is made up of fusable links, conducting terminal 2 and insulation crust.The difference of this embodiment and embodiment one is: fusable links is made up of an one metal wire 1 and a supporting mass 4, this supporting mass 4 can be an insulator, also can be a resistance, supporting mass 4 plays the effect of supporting fixing metal silk 1, and the performance of whole cartridge fuse is constant.

Other sees also shown in Figure 5, is the embodiment four of a kind of cartridge fuse of the utility model, still is made up of fusable links, conducting terminal 2 and insulation crust.This embodiment with the difference of embodiment two is: insulation crust is cooperated by the housing 3 of the uncovered end of end sealing and end cap 31 and forms enclosed construction, offer two jacks 33 on the end cap 31, housing 3 covers on the wire 1 outer and supporting mass 4 of fusable links, two tinned wirds by conducting terminal 2 pass two jacks 33, and end cap 31 lids are located at the opening end of housing 3.

Point out at last; the utility model conducting terminal 2 can also be except that lead; other electric conductor as sheet metal etc.; insulation crust can also be other structure and shape, as directly melting notes outside fusable links by insulating material, as long as can cover on outside the fusable links; playing the insulation protection effect gets final product; the shape of supporting mass 4 is not subjected to diagram restriction in the fusable links, and the various structures of fusable links, conducting terminal 2 and insulation crust can combination in any, and concrete combining structure is not restricted to the described embodiments.

Claims

1, a kind of cartridge fuse, be made up of fusable links, conducting terminal and insulation crust, it is characterized in that: insulation crust is closed, and insulation crust covers on outside the fusable links, two conducting terminals stretch in the insulation crust, and the two ends of fusable links are welded respectively and fixed a conducting terminal.
