Welding device for electrical engineering wire connection

Abstract

A welding device for electrical engineering wire connection is provided with a handle, a power socket is fixed to the tail end of the handle, a temperature controller is connected to the front end ofthe handle, a U-shaped support is fixed to the front end of the temperature controller through a short pipe, and the U-shaped support is connected with a tin pot with a heating element. A power switchbutton and a temperature control rotary knob of a temperature control circuit extend out of a panel of the temperature controller. The temperature control circuit is composed of a switch k1, a bridgerectifier, a one-way silicon controlled rectifier SCR, a slide rheostat RP, a resistor R1, a diode D5, a resistor R2 and a capacitor C. The tin pot is made of a titanium alloy, a layer of mica sheetand a layer of heating resistance wire wrap the periphery and the bottom surface of the tin pot, and the outer layer of the heating resistance wire is further wrapped by a layer of insulating mica sheet and sleeved with a metal protective cover. The welding device has the beneficial effects that an open fire operation mode is avoided, and the heating temperature of the tin pan can be controlled. The wire welding quality and the operation safety are improved.

Description

technical field [0001] The invention relates to a welding device, in particular to a welding device for connecting electrical engineering wires. Background technique [0002] When conducting wire connection work in electrical engineering, in order to ensure the quality of wire connection, it is usually necessary to carry out tin-hanging welding on the wound wires. The traditional method of hanging tin welding is to put the solder bar in the tin pot, heat the tin pot with a blowtorch, insert the wire joint into the tin pot, and perform hanging tin welding on the wire joint. This welding method has two disadvantages: one is to use a blowtorch to operate with an open flame, which is very easy to cause a fire and has serious safety hazards; the other is to heat the tin pot with a blowtorch and cannot accurately control the temperature of the tin pot, and the temperature of the tin pot is too low The hanging tin is uneven, and the hanging tin is not full if the temperature is to...

AI Technical Summary

Problems solved by technology

However, there are still two defects in this patented product. One is that the diameter of the heating tube is small, and it is not easy to operate during soldering, which makes the solder not full enough; the other is that it is still impossible to accurately control the soldering temperature.
