AI Technical Summary

Problems solved by technology

Especially in the case of using punching holes to connect ultra-thin wires to electrical connectors, the conductors are very small, so the force of the stabbing part of the electrical connectors to keep the wires is very weak, the connection strength is very low, and the reliability is lacking.

Embodiment 1

[0057] In 45% by volume of ABS resin (manufactured by Toray, Toyo Lak 441), 40% by volume of lead free solder (manufactured by Fukuda Metal Foil Powder Industry, Sn-Cu-Ni-AtW-150) and copper powder (Fukuda Metal Foil Powder Industry Co., Ltd., FCC-SP-77, average particle size 10 μm) 15% by volume, put into a mixer set at 220°C (Moriyama Manufacturing Co., Ltd., 2-axis pressurized type), form the heating and holding time, and use a rotation speed of 25 ~50rpm kneading for 20 minutes, the heat-plasticized solder is dispersed in the resin in a semi-molten state.

[0058] The kneaded body was granulated with a plunger extrusion granulator (TP60-2 type manufactured by Toshin) at a mold temperature of 200-240° C. to produce granules. The pellets were injection-molded in a mold (mold temperature normal temperature to 150° C.) with an injection molding machine (KS-10B manufactured by Kawaguchi Steel Co., Ltd.) at a set temperature of 230 to 280° C. The resulting injection molded prod...

Embodiment 2

[0061] 40% by volume of lead free solder (manufactured by Fukuda Metal Foil Powder Co., Ltd., Sn-Cu-Ni-AtW-150) and copper powder (manufactured by Fukuda Metal Foil Powder Co., Ltd. , FCC-SP-77, average particle size 10μm) 15% by volume, put it into a kneader (Moriyama Manufacturing Co. Do not raise the temperature of the kneading body above 235°C, reduce the speed, cool it, etc., knead for 20 minutes to make it heat-plasticized, and disperse the solder in the resin in a semi-molten state. The dispersion state of the solder in the kneaded body was observed with an optical microscope, and the solder was uniformly dispersed in the resin with a size of about 5 μm.

Embodiment 3

[0063] In 35% by volume of ABS resin (manufactured by Toray, Toyo Carat 441), 55% by volume of lead free solder (manufactured by Fukuda Metal Foil Powder Industry, Sn-Cu-Ni-AtW-150) and copper powder (Fukuda Metal Manufactured by Foil Powder Industry, FCC-SP-77, average particle size: 10 μm) 10% by volume, the total metal component is set to 65% by volume, and the mixture is put into a kneader set at 220°C (manufactured by Moriyama Seisakusho, 2 shafts Pressurized type) to form a heating holding time, kneading with a rotation speed of 25-50rpm for 20 minutes to make it thermally plasticized, and disperse the solder in the resin in a semi-molten state.

[0064] The kneaded body is granulated in a plunger extrusion granulator (TP60-2 type manufactured by Dongshin) with a mold temperature of 200-240°C to make granules. Using the pellets, injection molding was performed in a mold (mold temperature, normal temperature 150° C.) with an injection molding machine (KS-10B manufactured ...

Abstract

An electrical connector using resin solder, an electrical connector and a wire connection method thereof, the purpose of the present invention is to include that the connection of wires to the electrical connector does not require welding, and the connection of extremely thin wires to the electrical connector can be completed by an automatic machine. The electrical connector (100) of the present invention includes: a first connection part (110) connected to or fitted with a corresponding member, and a second connection part (120) connected to the conductor (210) of the electric wire (200). The electrical connector (100) forms at least the part of the conductor (210) of the electric wire (200) of the second connection part (120) connected to the lead-free ultra-high-conductivity plastic formed of the conductive resin composition.

Description

technical field [0001] The present invention relates to the technical field of connecting electric wires, using joints, contacts, piercing contact components, etc. as examples, using electrical connectors connected to corresponding components or fitted with corresponding components, and electrical connectors used therefor. Lead-free ultra-high-conductivity plastic electrical connectors and electrical connectors composed of non-conductive resin compositions. Background technique [0002] For the methods of connecting electric wires to connectors, contacts, piercing contact components, etc., there are methods of using welding, methods of punching, methods of pressing and crimping. In the case of punching, the electrical connector is provided with a stabbing portion, and the stabbing portion breaks through the wire to the conductor, thereby connecting the wire to the electrical connector. In the case of pressing, the electrical connector is provided with a barrel, and the barr...
