Conductive terminal and its drip flake method

Abstract

The invention discloses a conduction terminal, comprising a welding part and solder, wherein, the welding part comprises a bottom face and a side wall formed by the bottom face extended upward, a soldering film on the welding part is covered on the bottom face and the side wall of the welding part upward from the bottom face of the soldering part. Compared with prior art, the conduction terminal of the invention has the advantages that because the soldering tin on the welding part of the conduction terminal of the invention is film-shaped, the electric conductor is easy to be welded on a basal plate and the phenomenon of the short circuit and the connection of the soldering tin is not occurred. In order to make the soldering film of the conduction terminal, a fixture is provided, the fixture is provided with a plurality of storage tanks which are the same in size; equal amount of the solder is put into all storage tanks, the fixture is heated until the solder is melted, the welding part of the conduction terminal is correspondingly inserted in the storage tanks, thereby the solder is plated on the conduction terminal; as a result, after the solder is cooled down, the solder which is soldering film-shaped is coated on the conduction terminal.

Description

【Technical field】 [0001] The invention relates to a conductive terminal, in particular to a conductive terminal densely accommodated in an insulating body. The invention also relates to a method for manufacturing the welding film of the welding part of the conductive terminal. 【Background technique】 [0002] At present, most connectors are welded on the substrate by soldering the soldering part of the conductive terminal, and the conductive terminal usually includes a butt joint part and a welding part in design. However, most of the solder in the soldering part of the conductive terminal is spherical, please refer to Figure 1, which is a known shape of the soldering part of the conductive terminal, and it also covers a very thick solder 13 around the solder film 12 of the soldering part to make the soldering part The soldering portion of the conductive terminal forms a tin ball shape. [0003] For example, Taiwan Patent No. 093115924 discloses a typical electrical connect...

AI Technical Summary

Problems solved by technology

Because the number of conductive terminals is large, they are very densely accommodated in the insulating body, and the distance between the conductive terminals is very small, so the conductive terminals are easy to short circuit during the welding process, and because the solder in the traditional welding part is spherical, so in During the welding process, it is easy to make each solder into one piece
