Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
The metal tube resistor original part of the present embodiment, as shown in Figure 1, including 12 and of resistance wire of metal tube 11, spring like
Two leading-out terminals 13,11 lower end of metal tube are the cecum of indent, and upper end is open end, which is welded with flange spiral shell
Mother 14, for the resistor to be fixed to each other with periphery using equipment.Including the magnesia tube 15 as insulation tube, magnesia tube
15 open along its length there are two through-hole, and the inner end of two leading-out terminals 13 is inserted into respectively in two through-holes, two exits
The outer end of son 13 is extended outside metal tube 11, and resistance wire 12 is through round in the two through-holes, and magnesia tube 15 is convenient for will
Resistance wire 12 is maintained in place of 11 center of metal tube, and resistance wire 12 and metal tube 11 maintain a certain distance.Resistance wire
Inner end of 12 both ends respectively with two leading-out terminals 13 is fixed.Magnesia powder 16 is filled in the through-hole of magnesia tube 15,
Magnesia powder 16 is also filled between 11 inner wall of 15 outer wall of magnesia tube and metal tube.Such two leading-out terminals 13 are from gold
The same port for belonging to pipe 11 is pierced by, and occupied space is few, facilitates connection, meets the requirement of resistor single head extraction.And it is traditional
Two leading-out terminals of resistor are attached separately to the both ends of metal tube, are what double end was drawn, therefore will be the two of resistor
There are patching operations space around end, occupied space is big, and it is inconvenient to operate wiring at two respectively.In Traditional Thinking, such as
Fruit will realize that the input section output end of resistor is located at same direction, often way be metal tube integrally bending is in U-shape, but this
Kind of structure manufacture difficulty is big, at high cost, and wiring position still will be there are biggish space, and the two segment that U-shaped metal tube is arranged side by side
Influence insulation performance close to each other.
In the present embodiment, the manufacturing method of resistor is manufactured using above-mentioned metal tube resistor, comprising:
Terminal fixing step is respectively fixed to two leading-out terminals 13 at the both ends of resistance wire 12；
It is intubated step and two leading-out terminals 13 is inserted into two of magnesia tube 15 from the same end of magnesia tube 15 respectively
In through-hole, until two leading-out terminals 13 are pierced by from the other end of magnesia tube 15, so that the resistance wire 12 of spring like is circuitous
It is through in two through-holes of magnesia tube 15 with returning；Using being installed with the magnesia tube 15 of resistance wire 12 and leading-out terminal 13 as one
In a entirety insertion metal tube 11；
Filling step fills magnesia powder 16, is filled in magnesia powder 16 in two through-holes of magnesia tube 15,
And it is filled between 11 inner wall of 15 outer wall of magnesia tube and metal tube；
The lock procedure executed after filling step seals the open end encapsulating of metal tube 11；
The draw step executed after lock procedure elongates metal tube 11 by special equipment, makes metal tube 11
Wall thickness reduction and diameter reduction, while the indent degree of cecum increases, to be compacted insulating powder.During elongate metal pipe 11,
The inner wall of metal tube 11 applies extruding force inwardly everywhere, presses more tight to the magnesia powder 16 in metal tube 11, is not in
The defect that the magnesia powder 16 at 11 middle part of metal tube loosens.The side wall of metal tube 11 also applies extruding force to cecum, so that cecum
The degree of indent is bigger, is compacted magnesia powder 16 inwardly.Assuming that the cecum of metal tube 11 is flush end, the cecum meeting during draw
It protrudes outwardly, compacting 16 effect of magnesia powder can be reduced.
The metal tube resistor original part of another embodiment, as shown in Fig. 2, metal tube 21, magnesia tube 25, leading-out terminal 23
It is identical as a upper embodiment with the structure of flange nut 24, the difference is that the resistance wire 22 of the present embodiment is spirally wound on oxidation
Outside magnesium pipe 25,22 upper end of resistance wire enters, resistance wire fixed with a wherein leading-out terminal 23 from the upper port of magnesia tube 25
22 lower end upwardly extends fixed with another leading-out terminal 23 from the inside of magnesia tube 25.It is wound with resistance wire 22 and draws
The magnesia tube 25 of terminal 23 is inserted into metal tube 21 as a whole out, and between 21 inner wall of this entirety and metal tube
Magnesia powder 26 is filled, also is used to fix the inner end of leading-out terminal 23 filled with magnesia powder 26 in magnesia tube 25.Upper one
The resistance wire 22 of embodiment is spring like, and resistance wire 22 is too thin or too thick all around not going out spring like, therefore to resistance wire 22
Specification has certain requirement.Resistance wire 22 is wound in magnesia tube 25 by the present embodiment, can using thinner resistance wire 22 come
Meet big resistance value requirement.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
