Abstract

A novel direct connection method for metal wires is mainly used for connection of a relatively thick metal wire with the diameter larger than or equal to 0.1 millimeter and a relatively thin metal wire with the diameter less than or equal to 0.1 millimeter. The method comprises the specific steps as follows: one end of the thick metal wire is hit to be flat and then is sheared into a strip with a pair of scissors; the strip part is bent to form a 90-degree angle; and one end of the thin metal wire is placed at the bending angle part, then the bending angle is compressed, and the connection is finished. The method provided by the invention is mainly used for circuit welding of precision instruments such as a conductance cell in a gas chromatograph; and since the connection point is small, so that the method has less influence to the resistance of a circuit compared with tin soldering and other methods. According to the improved method provided by the invention, the diameter (or width) of the joint can be less than or equal to the sum of the diameters of the two connected conducting wires or even less than the diameter of the thick metal wire.

Description

Novel direct connection method for metal wires

Technical field

The invention belongs to electrical technology field, particularly a kind of method of attachment of superfine wire.

Background technology

Till now, the method for attachment in production and life is mainly welding, bonding, be spirally connected, and riveted joint and joggle.Welding is mainly used in the connection of metal, and melting welding temperature is high, and soldering makes the error of soldering tip resistance larger, and such technology is all not suitable for the connection of the superfine wire in precision instrument.Bonding, although various wires can be coupled together, bonding head can not make electric current pass through, and is not suitable in the specification requirement of energising so bonding.And bonding, be spirally connected, rivet the specification requirement that is more not suitable for being connected superfine wire with the method for attachment of joggle.This technology does not need above-mentioned method superfine wire and binding post can be coupled together, and avoids high temperature and other destruction.

Summary of the invention

The present invention seeks to overcome prior art above shortcomings, a kind of Novel direct connection method for metal wires is provided.

Novel direct connection method for metal wires provided by the invention, being connected between the relatively thin plain conductor of the relatively thick plain conductor that is mainly used in diameter >=0.1 person of outstanding talent rice and diameter≤0.1 millimeter, the concrete steps of the method are as follows:

1st, one end of crude metal wire is pounded into a piece plain film shape, then with scissors, be cut into fillet;

2nd, more above-mentioned fillet position is bent to the angle that is less than 90 degree;

3rd, one end of thin plain conductor is placed on to described corner (Fig. 1 the 4th step), then bent angle is compressed, connection completes.

Advantage of the present invention and good effect:

The inventive method is mainly used in the circuit welding of precision instrument, as the conductance cell in gas chromatograph, because tie point is little, little by methods such as solderings to the Resistance Influence ratio of circuit.

After repairing, described in the inventive method the diameter (or width) of junction can be less than or equal to two wires that are connected diameter and, be even less than the diameter of crude metal wire.

Accompanying drawing explanation

Fig. 1 is the inventive method connection procedure schematic diagram.

Embodiment

Embodiment 1:

The connecting object of the present embodiment is: the superfine plain conductor of diameter≤0.05 person of outstanding talent's rice, and with the crude metal wire of 1 millimeter of diameter.

The concrete Connection Step of the method is as shown in Figure 1:

1, be ready to the crude metal wire of 1 millimeter of diameter;

2, one end of above-mentioned crude metal wire is pounded into a piece plain film shape;

3, then with scissors, the piece of writing plain film shape in 2 steps is cut into narrow strip;

4, again the fillet position in 3 steps is bent to the angle that is less than 90 degree;

5, one end of the superfine plain conductor of diameter≤0.05 person of outstanding talent's rice is placed on to corner;

6, bent angle is compressed, connection completes again.

Claims (1)

1. a Novel direct connection method for metal wires, is characterized in that the method is for being connected between the thin plain conductor of the crude metal wire of diameter >=0.1 millimeter and diameter≤0.1 millimeter, and the concrete steps of the method are as follows:

1st, flat is pounded into in one end of crude metal wire, then with scissors, be cut into fillet;

2nd, more above-mentioned fillet position is bent to the angle that is less than 90 degree;

3rd, one end of thin plain conductor is placed on to described corner, then bent angle is compressed, connection completes.
