Abstract
The utility model discloses a miniature tubular heater wire welded structure mainly includes heating pipe, nickel stick, wire sinle silk, wire, two nickel sticks are drawn forth to heating pipe one end, and insulating skin is got rid of and the wire sinle silk is exposed to wire one end, and the heliciform is twisted into to the wire sinle silk, and the nickel stick is stacked from top to bottom with the wire sinle silk and is placed, and the nickel stick puts on the upper strata, and the wire sinle silk is put on the lower floor, under the effect of welding utmost point and welding current, and the nickel stick becomes a whole with the welding of wire sinle silk. The utility model discloses a method of stick and wire sinle silk is drawn in spot welding has controlled the welding spot size of welding department, has kept certain distance with the heating pipe again for there is not withstand voltage scheduling problem behind the electrothermal tube finished product.
Description
Technical Field
The utility model relates to an electric heater's field, concretely relates to miniature tubulose heater wire welded structure.
Background
The existing welding technology has the following defects: the existing welding mode needs to increase a terminal to fix a lead and weld the other end, so that the sectional area of a welding part is larger, but the whole volume of a heating pipe is required in the actual process, and the problems of poor pressure resistance and the like can be caused when the welding part is larger in volume.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a miniature tubular heater wire welded structure.
The purpose of the utility model is accomplished through following technical scheme: the welding structure of the miniature tubular heater wire mainly comprises a heating pipe, nickel rods, a wire core and a wire, wherein two nickel rods are led out from one end of the heating pipe, an insulating skin is removed from one end of the wire, the wire core is screwed into a spiral shape, the nickel rods and the wire core are stacked up and down, the nickel rods are placed on the upper layer, the wire core is placed on the lower layer, and the nickel rods and the wire core are welded into a whole under the action of a welding electrode and welding current.
The distance between the wire core and the heating pipe is more than 2mm, the length of the welding area is 2-3 mm, the distance between the head of the wire core and the welding area is 1-2 mm, and the distance between the wire and the welding area is 2 mm.
The utility model has the advantages that: the structure is simple, the operation is convenient, the welding effect is good, the sectional area of the welding part is small, and the pressure of the lead can be borne.
Drawings
Fig. 1 is a schematic structural diagram of the present invention before welding.
Fig. 2 is a schematic structural diagram of the welded structure of the present invention.
Description of reference numerals: heating pipe 1, nickel stick 2, wire sinle silk 3, wire 4.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, the welding structure of the miniature tubular heater wire mainly comprises a heating pipe 1, nickel rods 2, a wire core 3 and a wire 4, wherein two nickel rods 2 are led out from one end of the heating pipe 1, an insulating skin is removed from one end of the wire 4, the wire core 3 is exposed, the wire core 3 is twisted into a spiral shape, the nickel rods 2 and the wire core 3 are stacked up and down, the nickel rods 2 are placed on the upper layer, the wire core 3 is placed on the lower layer, and the nickel rods 2 and the wire core 3 are welded into a whole under the action of a welding electrode and welding current.
The distance A between the wire core and the heating pipe is more than 2mm, the length of the welding area C is 2-3 mm, the distance B between the head of the wire core and the welding area is 1-2 mm, and the distance D between the wire core and the welding area is 2 mm.
Because the heating pipe diameter is very little, the easy and heating pipe outer wall of solder joint takes place the contact in welding process, makes the electrothermal tube produce withstand voltage bad, takes place the short circuit electric leakage even, the utility model discloses a method that the stick and wire sinle silk were drawn in the spot welding has controlled the solder joint size of welding department, has kept certain distance with the heating pipe again for there is not withstand voltage scheduling problem behind the electrothermal tube finished product.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
