Description of the Related Art In recent years, the performance of automobiles and general industrial equipment has been improved, which is considered to be the result of the application of various sensors. Along with this, the number of signal circuits for passing minute voltages and currents has increased, and the processing capability of the CPU for processing the information of these signal circuits to control the system has also improved.

て錫めっき電線が使用されるようになった。However, when the number of parts handling such minute voltages and currents increases, the contact resistance and instantaneous interruption of the connection parts of electric wires and the like, which have not been a problem in the past, are greatly increased, which is why In addition to the conventional crimping method, ultrasonic welding method and resistance welding method have begun to be used as a method for joining electric wires, and tin-plated electric wires have been used in the conventional mechanical crimping method.

Tear strength is lower than mechanical crimping, so it is necessary to devise a method to protect the welded part. Furthermore, if the wire is thin, there is a problem that the damage during welding is large and the mechanical strength of the welded part is reduced. .

る効果が薄れる。In addition to the natural oxide film on the surface of the electric wire, there are some organic compound coatings such as plasticizers and lubricants that are attached when the vinyl chloride or the like is coated and extruded. An organic film is formed on the surface of the electric wire. In order to eliminate the adverse effects of these contaminated coatings (oxide coating + organic coating), a plurality of grooves are formed on the inner surface of the crimp terminal in the direction orthogonal to the direction of the wire to form protrusions called serrations. It is considered to break through the contaminated film by serration to remove the contamination of the electric wire and to obtain good metal joining, but in this case, the edges of the serration become gentle with the abrasion of the molding die of the crimp terminal, The effect of breaking through the contaminated coating on the surface of the wire is weakened.

がある。On the other hand, tin-plated electric wires have good contact reliability because a new metal surface of tin appears due to plastic deformation during crimping and a gas-tight structure is obtained. Has only a crimped portion with a length of about several mm to 1 cm, but the whole electric wire must be tin-plated due to the plating process, and there is a problem that the material is extremely wasteful.

問題がある。Further, a method of applying a conductive paste prepared by dissolving a powder of a noble metal, copper, carbon or the like in an organic resin to an electric wire and press-bonding the electric wire has been considered, but in this case, an increase in contact resistance when the resin is hardened or Since gas is released due to evaporation of the resin or decomposition of the resin in a high temperature environment, the released gas reacts with the components in the ambient atmosphere and adheres to the pressure-bonded portion, forming a film and increasing contact resistance, Depending on the type of organic substance, there is a problem that the resin of the connector housing may be melted or damaged.

確保される。According to the present invention, when the metal powder softer than the wire material is applied, the metal powder is deformed by the impact at the time of crimping the crimp terminal and adheres to the surface of the wire. Since the gap between the wires is filled, the contact area between the wires and between the wires and the crimp terminals is increased, and the contact resistance is reduced.
Since the metal powder is softer than the wire material, even if cold heat shock or mechanical vibration is applied to the crimp terminal or wire, the shock to the contact surface is softened and the long-term stability of the contact resistance is secured. .

Good metallurgical bonding is obtained, and the pressure applied during crimping is concentrated on the hard conductive powder, so even with low pressure, the hard conductive powder bites into the wire sufficiently, and thermal shock and mechanical vibrations are applied to the crimp terminals and wires. Even when added, good electrical connection with low contact resistance can be maintained, stable contamination film removal effect can be obtained, and performance reproducibility during mass production is also excellent.

By doing so, the contact resistance is lowered by the same action as in the case of the invention of claim 1, the contamination of the electric wire is removed, and good metal bonding is obtained.

増大に寄与しないという不都合もない。By the way, when the particle size of the metal powder is 80 to 400 mesh as described in claim 3, the metal powder is 80
As in the case where the metal powder is finer than 400 mesh, it is difficult for metal powder to enter the gaps between the wires, and it does not fall off before crimping. Also, there is no inconvenience that the metal powder is not easily crushed and does not contribute to the increase of the contact area.

ないという不都合もない。Further, when the particle diameter of the hard conductive powder is 70 to 200 mesh as described in claim 4, the hard conductive powder is present in the gap between the individual wires as in the case where the hard conductive powder is coarser than 70 mesh. It does not easily get in and does not fall off before crimping. As with hard conductive powder finer than 200 mesh, the effect of the wedges driven between the wires during crimping or between the wire and crimping terminals diminishes and contact resistance is reduced. There is no inconvenience of not contributing to the reduction.

Prior to crimping the crimp portion of the electric wire 2 constituted by the above with the crimp terminal 3, the crimp portion of the electric wire 2 is coated with the metal powder 4 having a particle size of 80 to 400 mesh, which is made of tin, lead or solder, which is softer than soft copper. At the same time, a powder 5 of copper or nickel or a metal of tungsten or molybdenum having a particle diameter of 70 to 200 mesh, which is a hard conductive powder harder than soft copper, is applied to the crimping portion of the electric wire 2 and then, as shown in FIG. As shown, the crimp terminal 3 is crimped by a crimping machine.

なる。As described above, when the metal powder 4 softer than the soft copper, which is the material of the wire 1, is applied, the metal powder 4 is deformed by the impact at the time of crimping and adheres to the surface of the wire 1. In order to fill the gaps between the wires 1, the wires 1 and 1-
The contact area between the crimp terminals 3 becomes large and the contact resistance becomes low.

The long-term stability is assured without increasing even after long-term use.

性能再現性も得られる。On the other hand, when the metal powder 5 as hard conductive powder which is harder than the soft copper which is the material of the strand 1 is applied,
As shown in FIG. 3, since the metal powder 5 bites into the strand 1 by the impact at the time of crimping and the contamination film 6 on the surface of the electric wire 2 is pierced, the contamination of the electric wire 2 is removed and the stable contamination film is removed. The effect can be obtained, good metal joining can be obtained by contact between fresh metals, and moreover, as in the case of forming serrations on the inner surface side of the crimp terminal as in the conventional case, the molding die of the crimp terminal can be formed. The effect of removing the contaminated film due to the abrasion of the edges of the serration due to the abrasion does not decrease, and the stable effect of the contaminated film removal and the excellent performance reproducibility during mass production can be obtained.

ち得る。Further, since the pressing force at the time of crimping is concentrated on the metal powder 5 having a small pressure, the metal powder 5 sufficiently digs into the wire 1 even with a low pressing force, and the thermal shock or mechanical vibration causes the crimping terminal or the electric wire 2. Good electrical connection can be maintained even when added to.

尚、図４には比較のために、従来の圧着法による場合の
同様のデータも一緒に示してある。By the way, a 1.25 sq electric wire 2 composed of 50 pieces of annealed copper wire 1 having a diameter of 0.18 mm, a crimp terminal 3 composed of brass, and metal powders 4 and 80 composed of 80-mesh tin.
A cold heat shock endurance test was conducted using a powder 5 made of copper as a hard conductive powder for the mesh, and the initial contact resistance value before the start of the test and the cold heat shock with -40 to 120 ° C for 30 minutes each as one cycle When the contact resistance value after endurance was measured after repeating 300 cycles, it was as shown in FIG.
For comparison, FIG. 4 also shows similar data obtained by the conventional crimping method.

とがわかる。As is apparent from the results of FIG. 4, when the metal powder 4 made of tin, which is softer than the wire material, is applied, and the powder 5 made of copper, which is harder than the wire material, is applied, the initial contact is made. It can be seen that the resistance value is decreased by one digit compared with the conventional one, and the change in the contact resistance value between the initial stage and the endurance is smaller than the conventional one, and the stability in the durability test is remarkably increased.

はない。Further, since only the wire 1, the metal powder 4 and the powder 5 are present in the crimping portion, there is an increase in contact resistance and a high temperature environment as in the case of using a conventional conductive paste made of an organic resin. There is no inconvenience caused by the gas release in the above.

都合もない。By the way, the particle size of the metal powder 4 is 80 to 400.
With a mesh, unlike the case where the particle size is coarser than 80 mesh, the metal powder does not easily enter the gaps between the individual wires and does not fall off before crimping. Even when each strand is deformed, the metal powder is not easily crushed and does not contribute to the increase of the contact area.

When a mesh is used, as in the case where the particle size is coarser than 70 mesh, the metal powder 5 does not easily enter the gaps between the individual wires 1 and does not drop before crimping. In addition, there is no inconvenience that the effect of the wedge driven between the wires 1 or between the wires 1 and the crimp terminals 3 at the time of crimping is weakened and does not contribute to the reduction of the contact resistance.

することができる。Therefore, according to the above-described embodiment, by applying the metal powder 4 softer than the material of the wire 1 to the crimping portion of the electric wire 2, each wire 1 is deformed by the deformation of the metal powder 4 at the time of crimping. It is possible to fill in the gaps between the wires 1 and 1
-The contact area between the crimp terminals 3 can be increased to reduce the contact resistance.

ができる。Furthermore, since the metal powder 4 is softer than the material of the wire 1, even if a cold heat shock or mechanical vibration is applied to the crimp terminal 3 or the electric wire 2, it is possible to soften the shock to the contact surface. It is possible to secure long-term stability of contact resistance.

Since the metal powder 5 bites into the element wire 1 at the time of crimping and the contaminated coating film 4 on the surface of the electric wire is pierced, contamination of the electric wire can be removed and a good metal joint with low contact resistance can be obtained.
Moreover, it is possible to obtain a stable contamination film removing effect and excellent performance reproducibility during mass production.

Even in the case of adding to 2, it is possible to maintain a good electrical connection.

る。As described above, according to the first aspect of the present invention, since the metal powder softer than the wire material is applied, the gap between the wires is deformed by the deformation of the metal powder during crimping. It is possible to bury it, there is no decrease in mechanical strength as in the case of the conventional welding method, and there is no inconvenience such as tin-plated electric wires, and it is easy to increase the contact area between each wire and between the wire and crimp terminals. The contact resistance can be reduced, and since metal powder is softer than the wire material, it is possible to soften the impact on the contact surface even when a thermal shock or mechanical vibration is applied to the crimp terminal or wire. While long-term stability of resistance can be ensured, the hard conductive powder that is harder than the wire material is applied to the crimping part of the wire. Can break through the contaminated coating of It is possible to obtain a good metal joint with low contact resistance by removing the contamination of the above, and also to obtain a stable contamination film removing effect and excellent performance reproducibility during mass production. Due to the concentrated action on the wire, the hard conductive powder is sufficiently dig into the wire with a low pressing force, and it is possible to maintain a good electrical connection even when a thermal shock or mechanical vibration is applied to the crimp terminal or the wire. , It is extremely suitable for joining terminals-electric wires or electric wires-electric wires of a wire harness in automobiles and general industrial equipment.
