Description

A kind of capping type resistance

Technical field

This utility model relates to resistance field, is specifically related to a kind of capping type resistance.

Background technology

Resistance is a current limiting element, after being connect in circuit by the two ends pin of resistance, limits and is connected by it The size of current of branch road.In existing circuit board is processed, by artificial or chip mounter, resistance is arranged on electricity On the plate of road, process especially with chip mounter, improve circuit board working (machining) efficiency, and be beneficial to add on a large scale Work produces.

Resistance is generally divided into plug-in unit resistance and Chip-R, particularly Chip-R, it is simple to use chip mounter real The processing of existing automatization.But, the pin of existing Chip-R is provided in wherein on end face, at paster electricity In the packing process of resistance and in the course of processing of employing chip mounter, it is ensured that the side of Chip-R pin end face To.This not only increases workload, also additionally to increase relevant device feature on baling press with chip mounter, Improve production cost.

Meanwhile, when using human weld's resistance, Chip-R is unfavorable for human weld, needs to change plug-in unit Resistance, reduces the working (machining) efficiency of circuit board, and increases corresponding cost, such as the replacing of circuit board resistance pins mouth.

Utility model content

The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, it is provided that a kind of A kind of capping type resistance, improves resistance packing and the efficiency of processing.

This utility model solves its technical problem and be the technical scheme is that a kind of capping type resistance of offer, Including:

Porcelain core；

Conductor wire, this conductor wire is wound on porcelain core；

Protective layer, this protective layer covers on described porcelain core and conductor wire；

Copper block, this copper block is respectively overlay at two end faces and the lateral edge thereof of porcelain core, this copper Matter block all electrically connects with conductor wire, and this copper block is as the pin of described capping type resistance.

Wherein, preferred version is: this copper block is open circles tubbiness.

Wherein, preferred version is: the outer surface of this copper block is provided with tin coating.

Wherein, preferred version is: the outer surface of this protective layer is cylindrical structure.

Wherein, preferred version is: this protective layer is silicon resin coating layer.

The beneficial effects of the utility model are, compared with prior art, this utility model is by design one Capping type resistance, the both ends of the surface at porcelain core arrange two blocks, and realize electrical connection by conductor wire, formed Two electrode pins of resistance, it is simple to the packing of capping type resistance and processing, reduce workload, improve work Efficiency.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:

Fig. 1 is the structural representation of this utility model capping type resistance.

Detailed description of the invention

In conjunction with accompanying drawing, preferred embodiment of the present utility model is elaborated.

As it is shown in figure 1, this utility model provides the preferred embodiment of a kind of capping type resistance.

A kind of capping type resistance, including porcelain core 11, conductor wire 12, copper block 13 and protective layer 14, Conductor wire 12 is wound on porcelain core 11, and copper block 13 is arranged on porcelain core 11 two ends, and equal and conductor wire 12 electrical connections, protective layer 14 covers described porcelain core 11, conductor wire 12, prevents porcelain core 11, conductor wire 12 cause short circuit with external contact, simultaneously protection porcelain core 11, conductor wire 12.

Wherein, copper block 13 is respectively overlay at two end faces and the lateral edge thereof of porcelain core 11, this copper Matter block 13 all electrically connects with conductor wire 12, and this copper block 13 is as the pin of described capping type resistance.

Further, copper block 13 is in open circles tubbiness, it is simple to resistance is packed in either direction Or processed, especially by chip mounter by capping type resistance welding on circuit boards, it is not necessary to distinguish block The welding direction of formula resistance.Meanwhile, in order to improve overall packing and the convenience of processing of capping type resistance, The outer surface of protective layer 14 is cylindrical structure, and the cross-sectional area of protective layer 14 is less than copper block 13 Cross-sectional area.

Or, copper block 13 is in square opening barreled, by arbitrary copper block 13 and circuit The position soldering of plate corresponding pin；Or other be easy to the position soldering of circuit board corresponding pin barreled knot Structure.

Further, the outer surface of copper block 13 is provided with tin coating, improves and circuit board corresponding pin The convenience of the soldering of position, is more easy to welding.

In the present embodiment, it is provided that porcelain core 11, conductor wire 12, copper block 13 and protective layer 14 excellent Selecting scheme, if porcelain core 11 is containing the highly thermally conductive porcelain core of aluminum, its aluminum content is 70%；Conductor wire 12 closes for nickel chromium triangle Gold thread or constantan line, a diameter of the 0.05 of conductor wire～0.16mm, preferably 0.08mm；Protective layer 14 is silicon resin coating layer.

In the present embodiment, capping type resistance is preferably electric fuse resistance.

As described above, only this utility model most preferred embodiment, is not intended to limit this utility model Scope, all equivalence changes made according to this utility model claim or modify, be all this practicality newly Type is contained.
