Embodiment Construction

[0016] As shown in the accompanying drawings, the hollow copper tubes of Φ4mm are cut into tube blanks 1 one by one, which have a copper column surface 31, and each tube blank 1 is 20mm long, and the copper tubes are copper tubes or H62-H65 brass tubes. A special mold 5 is clamped with a drill chuck 6. The mold 5 has a mirror-surface semi-spherical mold cavity 51. The inner diameter of the mold cavity 51 is also 4mm, which is slightly longer than a hemisphere. After the tube blank 1 is fixed by the clamp, the mold 5 clamped on the chuck 6 of the drill press is pressed into one end of the tube blank 1 in a very short time, and the resulting The high temperature will make the end copper tube welded and sealed into a semi-spherical surface 32, and the tube blank 1 will be processed into a semi-finished round-headed hollow copper tube 2; diameter to form a wire crimping joint 33 with a smaller diameter, so as to obtain an electrical plug-in element 3, and the surface of the plug-i...

Abstract

The hollow cylinder electrical connector comprises one end of semi-circle spherical surface made from a hollow copper tube by rubbing and welding and sealing opening and another end as necked-in wire pressure connector with cold extrusion technology. This product has the advantages both of circular copper column type and flat inserting plate, and has wide application.

Description

Technical field [0001] The invention relates to a basic electrical component, especially an electrical plug-in component and its manufacturing method. Background technique [0002] In electrical equipment such as household appliances, industrial equipment, and instruments, a plug for connecting wires is generally used to facilitate connection to a power socket. There are basically two types of plug-in components in the electrical plugs currently used. One type uses cylindrical solid-core copper columns. Because of its good electrical contact performance on the cylindrical surface, it is easy to use, safe and reliable, and is widely used all over the world. However, it consumes a lot of materials. my country is a country lacking in copper ore resources. Therefore, another type of plug-in element is stipulated in the national standard, that is, the flat plug-in piece. The copper consumption rate of this kind of plug-in piece is low. In the same In the case of copper consumption...
