Abstract
The utility model discloses an electric welder with an electrostatic induction prevention function. The electric welder comprises a transformer, a rectifying diode, a cadmium-nickel battery, a resistor, an electric welder heating wire, an indicating bulb and a switch, direct voltage of the storage battery is used, operating voltage is low, and high-voltage electrostatic induction is avoided, so that electronic elements cannot be damaged in the welding process. The electric welder is small in size, easy to carry, low in cost and beneficial to popularization, and is provided with fewer elements.
Description
Technical field
The utility model relates to a kind of electric iron, relates in particular to a kind of electric welding device with antistatic inducing function.
Background technology
Existing electric iron can only be operated indoor connecting with the mains, and the operating voltage height, damaged by high voltage electrostatic induction easily as some original paper in the electrical equipment such as cmos circuit, video recorder, computer, owing to need power supply, so can't use out of doors.
Summary of the invention
The purpose of this utility model provides a kind of electric welding device with antistatic inducing function with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises transformer, commutation diode, ickel-cadmium cell, resistance, electric welding device heating wire, pilot bulb and switch, the positive pole of described ickel-cadmium cell is connected with first end of described switch, the negative pole of described ickel-cadmium cell is connected with first end of described pilot bulb and first end of described electric welding device heating wire simultaneously, second end of described switch is connected with first end of described resistance and second end of described electric welding device heating wire simultaneously, second end of described resistance is connected with second end of described pilot bulb, the high-pressure side of described transformer is connected with alternating current, the positive pole of described commutation diode is connected with an end of the low-pressure side of described transformer, the other end of described step down side and the negative pole of described commutation diode respectively with negative pole and anodal corresponding connection of described ickel-cadmium cell.
The beneficial effects of the utility model are:
The utility model can be made power supply without the 220V line voltage, and what adopt is the 2.4V DC voltage of savings itself, with the form work of heavy-current discharge; Because operating voltage is very low, so there is not the high voltage electrostatic induction phenomenon, be very suitable for welding device or the equipment that is damaged by high voltage electrostatic induction easily as cmos circuit, video recorder, computer etc.; The utility model volume is small and exquisite, carries easily, is suitable for field work.
Description of drawings
Fig. 1 is circuit structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: the utility model comprises transformer T, commutation diode VD, ickel-cadmium cell E, resistance R, electric welding device heating wire RL, pilot bulb EL and switch S, the positive pole of ickel-cadmium cell E is connected with first end of switch S, the negative pole of ickel-cadmium cell E is connected with first end of pilot bulb EL and first end of electric welding device heating wire RL simultaneously, second end of switch S is connected with first end of resistance R and second end of electric welding device heating wire RL simultaneously, second end of resistance R is connected with second end of pilot bulb EL, the high-pressure side of transformer T is connected with alternating current, the positive pole of commutation diode VD is connected with an end of the low-pressure side of transformer T, the other end of transformer T low-pressure side and the negative pole of commutation diode VD respectively with negative pole and anodal corresponding connection of ickel-cadmium cell E.
As shown in Figure 1: the utility model mainly is made up of flatiron body and charger.The flatiron body is made up of solder horn RL, pilot bulb EL, ickel-cadmium cell E, switch S and resistance R.Utilize No. 2 ickel-cadmium cell E(voltage 2.4V of 2 joints), give solder horn RL heating with big current forms.The surface of solder horn RL is through corrosion-resistant anti-oxidant coating film treatment.The heating wire resistance that is closed in the solder horn RL is 0.4 Ω, and operating current is 6A, and the power of flatiron is about 15W, and temperature can reach 300 ℃-400 ℃, and the life-span is better than 20W internal heat type solder horn.Charger is made up of transformer T and commutation diode VD, and charging voltage is 2.6V, and charging current is 14OmA-180mA.
When using a period of time with iron, after descending, the voltage of ickel-cadmium cell can will connect between the ickel-cadmium cell two ends of lattice iron body and charger, and ickel-cadmium cell then is recharged.Because No. 2 ickel-cadmium cell capacity are big, the use of charging repeatedly again is so this electric iron is bound to obtain radio amateur's welcome.
