Abstract
The utility model discloses a quick assembly type fuse. The quick assembly type fuse comprises a fuse tube body, a fuse wire which is arranged in the tube body, and first copper caps which are tightly covered on two ends of the fuse tube body. Two ends of the fuse wire are respectively connected with the first copper caps on two ends of the fuse tube body. The fuse tube body and the first copper caps are in interference fit connection through a punching method. The outer ends of the first copper caps are in interference fit connection with second copper caps through a punching method. Leads are led out from the outer ends of the second copper caps. According to the utility model, the structure is exquisite and simple; the used tube body is just matched with the copper cap size; direct pressing is carries out, thus the tube body and the copper caps are in interference fit connection; glue used by gluing in the prior art is avoided; the steps of high temperature baking and curing are omitted; the requirement of same joint strength is met, and at the same time the production efficiency is greatly improved; and the fuse is not affected by environmental factors.
Description
[technical field]
The utility model relates to fuse field, particularly a kind of fast assembling fuse.
[background technology]
Existing conventional fuse structure, comprise body, be arranged on the lead-in wire of amplifying out on the fuse in body, the copper cap that is arranged on body two ends, copper cap, between copper cap and body owing to being to adopt glue bonding, need to carry out hot setting, be subject to such environmental effects after but glue curing is easy, as temperature and humidity variation can cause affecting adhesive strength, cause easily and come off, thereby affect useful life of fuse.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of contact performance good, is not subject to the fast assembling fuse of such environmental effects.
The purpose of this utility model is achieved in that it comprises fuse body, is arranged on the first bronze medal cap that fuse, enclosing cover in body is combined in fuse body two ends, the two ends of described fuse are connected on the first bronze medal cap at fuse body two ends, its improvements are: described fuse body and the first bronze medal cap linking together by process for stamping interference fit, the outer end of described the first bronze medal cap is also connected with the second bronze medal cap by process for stamping interference fit, and lead-in wire is drawn in the outer end of described the second bronze medal cap.
In said structure, described fuse body is earthenware or glass tube.
In said structure, described the first bronze medal cap and the second bronze medal cap are the cylinder-like structure of an end opening other end closure, and the external diameter of the internal diameter of described the first bronze medal cap and fuse body matches, and the internal diameter of the external diameter of described the first bronze medal cap and the second bronze medal cap matches.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is small and exquisite simple, the body using just mates with copper cap size, then directly pressing causes both interference fit to connect, and avoids using in prior art and glueds joint and the glue of employing, has saved the curing step of high-temperature baking, when reaching identical bond strength requirement, production efficiency is improved greatly, and the fuse of punching press combination is not subject to the impact of environmental factor, has extended the useful life of fuse.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[embodiment]
Below in conjunction with the drawings and the specific embodiments, the utility model is further described:
As shown in Figure 1, fast assembling fuse of the present utility model, it comprises fuse body 1, be arranged on the first bronze medal cap 3 that fuse 2, enclosing cover in body is combined in fuse body 1 two ends, and the two ends of described fuse 2 are connected on the first bronze medal cap 3 at fuse body 1 two ends; Described fuse body 1 and the first bronze medal cap 3 link together by process for stamping interference fit, and the outer end of described the first bronze medal cap 3 is also connected with the second bronze medal cap 4 by process for stamping interference fit, and lead-in wire is drawn in the outer end of described the second bronze medal cap 4.
Wherein, described the first bronze medal cap 3 and the second bronze medal cap 4 are the cylinder-like structure of an end opening other end closure, the external diameter of the internal diameter of described the first bronze medal cap 3 and fuse body 1 matches, the first bronze medal cap 3 carries out punching press combination with fuse body 1 by forcing press, formation interference fit connects, make the first bronze medal cap 3 fast enclosing cover be combined on fuse body 1 end; The internal diameter of the external diameter of described the first bronze medal cap 3 and the second bronze medal cap 4 matches, and is also to carry out punching press combination by forcing press, forms interference fit and connects, make the second bronze medal cap 4 fast enclosing cover be combined on the outer end of the first bronze medal cap 3.By impact style, utilize forcing press fast by fuse body 1, the first bronze medal cap 3 and the second bronze medal cap 4 sealing assemblings together, when having guaranteed the entire combination intensity of fuse, saved the hot setting that traditional adhesive bonding technique adopts, improve production efficiency, reached energy-saving and cost-reducing object.
Further, described fuse body 1 is made by pottery or glass fibre, has guaranteed the bulk strength of fuse, has avoided fuse body 1 to break in punching course or use procedure.
As selection, the utility model fuse through forcing press by after fuse body 1, fuse 2 and the first bronze medal cap 3 and the quick punching press of the second bronze medal cap 4 assembling, also can be at outer setting one insulating barrier of whole fuse, the outer end that is connected in the lead-in wire 5 on the second bronze medal cap is piercing in the outside of this insulating barrier.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection range of claim of the present utility model.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
