Abstract

The invention relates to a constant-temperature electric soldering iron for repairing a mobile phone. The constant-temperature electric soldering iron for repairing the mobile phone comprises a handheld part; the front end of the handheld part is connected with a heating part, and the tail end of the handheld part is connected to a power line; the front end of the heating part is provided with a soldering bit, a permanent magnet is arranged in the center of the inner cavity of the heating part and is connected with a contact spring plate through a small shaft, the outside of the permanent magnet is sleeved by a support frame, the soldering bit is fixedly connected with the support frame, and a soft magnetic metal block is mounted at the soldering bit; and the support frame is provided with a contact corresponding to the contact spring plate, and the contact is connected with a heater through a wire on which a magnetic switch is mounted. The constant-temperature electric soldering iron is simple in structure, the phenomenon that the soldering quality is affected because a soldering iron core is always in a heating state is avoided, the service life of the electric soldering iron is prolonged, and meanwhile, the electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of electric appliance maintenance equipment, in particular to a constant temperature electric soldering iron for mobile phone maintenance. Background technique [0002] For home appliance maintenance personnel, electric soldering iron is one of the necessary welding tools in maintenance work, and its quality directly affects the efficiency of maintenance work. Especially in the maintenance of mobile phones, it is often necessary to replace the components on the circuit board, which requires the use of a soldering iron, and the requirements for it are also very high. This is because the components of the mobile phone adopt the surface mount process, the components are small in size, highly integrated, the printed circuit is fine, and the pad is small. If the soldering iron is not selected properly, it is easy to cause human faults during the soldering process, such as false soldering, short circuit or even s...
