Ceramic electric soldering iron

Abstract

The invention relates to the technical field of heating equipment, and discloses a ceramic electric soldering iron. The ceramic electric soldering iron comprises a soldering bit, a handle, a ceramic heating body, a positive wire and a negative wire, and is characterized by further comprising a wire and a ground wire, wherein the negative wire is connected to the soldering bit, the positive wire is connected to the ceramic heating body, the wire is connected to the cathode wire at the front end of the ceramic heating body, the wire is connected with a control detection center (capable of detecting grounding voltage and grounding resistance), and the ground wire is connected with the handle. The ceramic electric soldering iron has the advantage of determining whether the grounding voltage is less than 2 mV and the grounding resistance is less than 2 Ohm.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a ceramic electric soldering iron. Background technique [0002] At present, electric soldering iron is an indispensable tool in the electrical industry and electronic production. It is used for welding components and their wires. Electrostatic discharge (ESD) is generated due to charge transfer caused by objects with different electrostatic potentials approaching each other or in direct contact during use. ), ESD will cause damage to the internal equipment of the electric soldering iron and reduce the service life. my country is a processing base of electronic products, and there are many electronic product processing enterprises all over the country. Most of the ESD control work of these enterprises has not been established in accordance with American standards. The ESD20.20 scheme requires the grounding voltage to be less than 2mV and the grounding resistance to be les...

[0002] At present, electric soldering iron is an indispensable tool in the electrical industry and electronic production. It is used for welding components and their wires. Electrostatic discharge (ESD) is generated due to charge transfer caused by objects with different electrostatic potentials approaching each other or in direct contact during use. ), ESD will cause damage to the internal equipment of the electric soldering iron and reduce the service life. my country is a processing base of electronic products, and there are many electronic product processing enterprises all over the country. Most of the ESD control work of these enterprises has not been established in accordance with American standards. ESD20.20 scheme requires grounding voltage <2mV and grounding resistance <2Ω

[0003] In the prior art, anti-static is carried out by directly grounding the shell or using a ceramic heating element. For example, the patent application number CN200520065808.4 discloses an AC-DC dual-purpose energy-saving anti-static constant-temperature silicon nitride electric soldering iron. , Welding nozzle, stainless steel sleeve, heat-insulating ceramic tube, inclined-plane heat-insulating ceramic tube and handle. There are 2 lead-out electrodes, and the electrostatic protection of the heating element cannot guarantee that the grounding voltage is <2mV and the grounding resistance is <2Ω
