Abstract

The utility model is a fuse wire combination construction, which comprises a combination seat, and two penetrative tinsels. One end of the utility model is pin end. The both two pin ends are respectively clad in the both two ends of a fuse wire. A cap is also combined with the combination seat. A tin layer is formed between the pin end and the fuse wire by carrying out instant current and high voltage. The effective connection can be achieved and the stability of the current conveyance can be ensured, well as the high quality fuse product can be provided by the utility model.

Description

The fuse combined structure

Technical field

The utility model relates to a kind of fuse structure.

Background technology

The employed fuse structure of general electronic products mainly includes a connecting support, is provided with two wires that run through, a wire wherein end is shorter, is made as the pin end, in order to the two ends in conjunction with a fuse, and the outside is sealed with a lid again, and two outer end wiry can be for being combined on the circuit board.

For fuse effectively is combined as a whole with pin end wiry, prior art is the two ends that two pin ends volume overlayed on fuse, make the two fixing in advance, permeate between the two from the outside with tin then, secure bond after cooling, though this kind construct certain degree in conjunction with fuse and pin end, but tin can only be local infiltration and in conjunction with the two, when fuse in use, the mobile of electric current can produce unsettled phenomenon, and cause the damage of fuse easily, even the destruction that causes electronic product.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: a kind of fuse combined structure is provided, and fuse wherein and pin end wiry are to be the structure that connects airtight fully, and on can guaranteeing to use, the stable flow of electric current, the safety function of performance fuse.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of fuse combined structure, it is characterized in that: include a connecting support, two wires that run through, the one end is the pin end, two pin ends coat the two ends that twist in a fuse respectively, also be combined with a lid on the described connecting support, form a tin layer by imposing immediate current and high pressure between described pin end and the fuse.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: fuse and pin end wiry are to be the structure that connects airtight fully, and on can guaranteeing to use, the stable flow of electric current, the safety function of performance fuse.

Embodiment

See also Fig. 1 to shown in Figure 5, the utility model includes connecting support 1, two wires 2 and a fuse 3 of fuse, wherein the two ends of fuse 3 are respectively pin end 21 coating of reeling of two wires 2, and the internal layer of described pin end 21 has a uniform tin layer 6 and seals the outer surface that envelopes fuse 3 fully.

When fuse 3 is the 21 coiling coatings of pin end, because the internal layer of pin end 21 just is covered with a very thin tin originally, at this moment, can utilizing up and down, two ends impose immediate current and high pressure, as shown in Figure 4, rely on high temperature and pressure, make the tin fusion, oppress pin end 21 and inner fuse 3 simultaneously, form combination closely, after cooling, just can obtain finished product as shown in Figure 5, wherein tin layer 6 fills completely between pin end 21 and fuse 3, has no the space, be to obtain best associativity, can provide electric current when circulation, have the function of high efficiency and high stability.

As Fig. 6, Fig. 7, shown in, also be combined with a lid 4 on the connecting support 1 of the present utility model.

Therefore, when fuse of the present utility model is being combined on other electronic product, be the insurance effect that can guarantee its best, improve whole fail safe.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.

Claims

1. fuse combined structure, it is characterized in that: include a connecting support, two wires that run through, the one end is the pin end, two pin ends coat the two ends that twist in a fuse respectively, also be combined with a lid on the described connecting support, form a tin layer by imposing immediate current and high pressure between described pin end and the fuse.
