Abstract

A precision resistance wire includes two column feet and a resistance wire body. Wherein, the column base is provided with a pin for inserting into the circuit board, and one end of the pin is provided with a joint portion with a larger outer diameter, and the resistance wire body is a U-shaped body bent from a metal rod. The body of the resistance wire is connected to the end of the joint part away from the pin through its two ends, which is a precision resistance wire. Whenever the specification of the precision resistance wire is changed, just cut off the required length of the metal rod, and then bend it into a The U shape can be welded to the column foot, so it does not need to make additional molding molds, which can greatly reduce costs and improve production efficiency.

Description

Precision resistance wire

Technical field

The utility model relates to a kind of essential electronic element, relates in particular to a kind of being convenient to and makes the Precision resistance wire of enhancing productivity, reducing cost.

Background technology

When the electric equipment desire is carried out difference in functionality, be to change the loop by Precision resistance wire, and adapt to the required resistance of different electrical equipment, this Precision resistance wire large and small also inequality, existing Precision resistance wire is on the whole as Fig. 6, shown in Figure 7, be provided with the resistive conductor body 50 of one section flat, the two ends of resistive conductor body 50 are concaved with a short slot 51 respectively, and short slot 51 is respectively in conjunction with a pin 60 that can be inserted on the circuit board.This pin 60 should form a junction surface 61 by end towards resistive conductor body 50, and junction surface 61 is provided with a shape and short slot 51 corresponding projections 610, and the projection 610 with pin 60 is riveting on the short slot 51 with the punch press punching out again.

From the above, resistive conductor body 50 and pin 60 all need the drift punch forming with given shape, punch riveting again, but because the size specification difference of Precision resistance wire, when therefore whenever obtaining a kind of order of different size, promptly need other mfg. moulding die, with punch forming resistive conductor body 50, according to the operation situation of existing industry, take 2-3 month to manufacturing a finished product by die sinking, not only consuming time, efficient is poor, and cost is high and competitiveless, and in addition improved necessity is arranged in fact.

The utility model content

In order to overcome the above-mentioned shortcoming that existing Precision resistance wire exists, the utility model provides a kind of improved Precision resistance wire, and it has is convenient to make the advantage of enhancing productivity, reducing cost.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of Precision resistance wire comprises the resistive conductor body; It is characterized in that being provided with two suspension columns, each suspension column is equipped with one so as to being inserted in the pin of circuit board, and a wherein end of pin is provided with the bigger junction surface of external diameter; Described resistive conductor body is one to have the U-shaped body at two ends, and this resistive conductor body is to be engaged in the end of the junction surface of suspension column away from pin by its two ends.

The beneficial effects of the utility model are, by above-mentioned technological means, should be standard specification product in order to the suspension column that is inserted on the circuit board, the resistive conductor body then is according to required specification intercepting Metallic rod, again Metallic rod is bent into the U type, to be welded in the junction surface end face of suspension column.Because it does not need to make mould in addition, so shaping speed is fast, efficient is high and can significantly reduce cost, to improve the shortcoming of prior art.

The number in the figure explanation:

10 suspension columns, 11 pins

12 junction surfaces, 120 jointing end faces

20,30,40,50 resistive conductor bodies

51 short slots, 60 pins

61 junction surfaces, 610 projections

Embodiment

See also shown in Figure 1, Precision resistance wire provided by the utility model comprises two suspension columns 10 and a resistive conductor body 20, this suspension column 10 is a copper product, it is provided with one for the pin 11 that is inserted in circuit board, a wherein end of pin 11 is provided with the bigger junction surface of external diameter 12, this junction surface 12 is away from being made as smooth jointing end face 120 on pin 11 1 end faces, for described resistive conductor body 20 welding.

Resistive conductor body 20 is one to have the U-shaped body of rod at two ends, and it is to be bent by a Metallic rod to form, the two ends of resistive conductor body 20 are welded on the jointing end face 120 of suspension column 10 Precision resistance wire.

And for example Fig. 4, shown in Figure 5 is that the utility model is established the

resistive conductor body

30,40 with different size, compares with aforesaid embodiment, and Fig. 4,

resistive conductor body

30,40 specifications shown in Figure 5 are less, and suspension column 10 specifications are then identical.

By aforesaid three embodiment as can be known, the utility model is standard specification product in order to the suspension column 10 that is inserted on the circuit board, be made as identical suspension column 10 corresponding to the circuit board of same type and (cooperate dissimilar circuit boards, the size of suspension column is also different), and can cooperate the resistive conductor body 20 of assembling various different sizes with a kind of suspension column, 30,40, and, each

resistive conductor body

20,30, as long as 40 manufacture is according to required specification intercepting Metallic rod, again Metallic rod is bent into U-shaped, the jointing end face 120 that is welded in suspension column 10 gets final product, it does not need to make mould in addition, so shaping speed is fast, the efficient height.The applicant studies the resistive conductor of different size, as long as can finish in one day, and because it does not need to make in addition mould, so can significantly reduce cost.
