Soldering iron tip and high-voltage cable plug welding method using the same

Abstract

The invention discloses a soldering bit and a high voltage cable plug welding method using the soldering bit. The soldering bit comprises a soldering bit body provided with a welding part and a heating part, the welding part and the heating part are connected in an adjacent manner, the welding part is in a pipe shape and is provided with a front end opening, the radial wall of the front end opening backwards forms a strip-shaped groove in the direction of the heating part to be communicated with the interior of the welding part, and therefore the welding convenience is promoted; in addition, the high voltage cable plug welding method is used in a matched manner, a winding tin wire is arranged in a connection copper base of a high voltage cable plug, the soldering bit body is heated to a welding temperature and is in contact with the winding tin wire, the winding tin wire fuses by a tin fusion time to complete welding, the welding convenience is promoted by the soldering bit body, and the better welding effect is achieved through the welding method.

Description

technical field [0001] The invention relates to a soldering iron tip, in particular to a convenient-to-use soldering iron tip and a high-voltage cable plug welding method using the soldering iron tip. Background technique [0002] see Figure 8 As shown, it is a high-voltage cable plug 90 in the prior art. The high-voltage cable plug 90 is mainly manufactured by integral injection molding, and a plurality of wiring copper seats 91 are covered with plastic substrates, and each wiring copper seat A power supply copper wire 92 is respectively pierced in 91, and the connection between the connection copper seat 91 and the power supply copper wire 92 needs to be welded, so that each wiring copper seat 91 and each power supply copper wire 92 are fixed and formed well through the molten tin formed by soldering. The electrical connection; welding is mainly by heating the soldering iron tip of the soldering iron table to a temperature suitable for welding, and melting the solder thro...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is an externally heated soldering iron station, which can only output a fixed power in use, so that the soldering iron tip of the soldering iron station cannot effectively control the proper soldering temperature in heating, when the soldering iron tip When it is inserted into the wiring copper seat 91, the plastic base material of the high-voltage cable plug 90 is likely to be melted due to excessive welding temperature. Although it will not affect the use effect, the appearance of the high-voltage cable plug 90 will be very ugly; And when soldering, the solder needs to be placed on the tip of the soldering iron in advance, and then the tip of the soldering iron is inserted into the wiring copper seat 91 for soldering. Because the tin is preliminarily placed on the tip of the soldering iron, the flux in the solder will be A large amount of fast volatilization affects the soldering effect, and the volatilized soldering flux can also cause environmental pollution; and, because of the pre-tinned mode, when the soldering iron tip is inserted into the wiring copper seat 91, the solder is easy to adhere to the power supply. The top of the copper wire 92 causes the problem of hanging tin, so that the molten tin cannot be effectively arranged on the bottom of the wiring copper seat 91, which not only leads to welding failure, but also reduces the amount of molten tin arranged at the bottom of the wiring copper seat 91. Affect the welding strength, so the existing technology needs to be improved
