Description
Technical field
The utility model relates to resistor technologies fields, and in particular to a kind of aluminum-housed resistor.
Background technique
Currently, there are two types of exits for aluminum casing resistor, one is using soft copper conducting wire to draw, another kind is using hard steel disc
It draws.Wherein, existing hard steel disc exit has the disadvantage that: 1) steel disc holds because stress or manual operation repeatedly are improper
The case where easily loosening causes product the bad phenomenons such as the unstable, open circuit of resistance value occur；2) plate steel disc is as exit
It is difficult to position during installation, and is unable to get good fixation in the longitudinal direction, cause to shift.
Summary of the invention
For the prior art there are above-mentioned technical problem, the utility model provides a kind of aluminum casing resistor that deriving structure is stable
Device.
To achieve the above object, the utility model the following technical schemes are provided:
A kind of aluminum-housed resistor is provided, including aluminum shell, resistor assembly and terminal assemblies, resistor assembly are fixed on aluminum shell
It is interior, and mutually insulated and thermally conductive between resistor assembly and aluminum shell；Terminal assemblies include mica baffle, sheet metal and bolt group
Part, sheet metal middle part punch forming go out right angle fixinig plate, and right angle fixinig plate is provided with bolt hole, and mica baffle is provided with to be worn for sheet metal
The hole location of the bar shaped location hole crossed and alignment bolt hole, right angle fixinig plate touch mica baffle, bolt assembly pass through bolt hole and
Hole location is to which mica baffle and sheet metal to be fixed to each other；Mica baffle is fixed on aluminum shell, sheet metal rear end electric connection resistance
Component, sheet metal front end are provided with wiring hole.
Wherein, the shape of resistor assembly is adapted with the inner cavity of aluminum shell, so that resistor assembly outer wall touch aluminum shell
Internal chamber wall.
Wherein, the top of aluminum shell is equipped with radiating fin.
Wherein, aluminum shell is hard aluminium alloy shell or fine aluminium shell.
Wherein, heat-conducting glue is filled between resistor assembly and aluminum shell inner wall.
The utility model has the beneficial effects that
The aluminum-housed resistor of the utility model, compared with prior art, sheet metal pass through the bar shaped positioning on mica baffle
Hole is positioned, and is positioned without using other additional positioning tools；It is solid to go out right angle for punch forming in the middle part of sheet metal itself
Stator is securely fixed between right angle fixinig plate and mica baffle using bolt assembly, solves the problems, such as that sheet metal is easy to loosen
Deriving structure is reliable and stable.

Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
The aluminum-housed resistor of the present embodiment, as depicted in figs. 1 and 2, including aluminum shell 1, resistor assembly 2 and terminal assemblies 3,
Aluminum shell 1 is hard aluminium alloy shell or fine aluminium shell, and the top of aluminum shell 1 is equipped with radiating fin 11.Resistor assembly 2 be it is common around
Line resistance, specifically details are not described herein, and resistor assembly 2 is fixed in aluminum shell 1, shape and the aluminum shell 1 of resistor assembly 2
Inner cavity is adapted, so that 2 outer wall of resistor assembly touch 1 internal chamber wall of aluminum shell.2 outer panel of resistor assembly is insulation board, resistance
Gap filling between 1 inner wall of component 2 and aluminum shell has heat-conducting glue, so that mutually insulated between resistor assembly 2 and aluminum shell 1
And it is thermally conductive.
In conjunction with shown in Fig. 3 and Fig. 4, terminal assemblies 3 include 31, two pieces of sheet metals arranged side by side 32 of a killinite baffle and with gold
Belong to the one-to-one bolt assembly 33 of piece 32,32 middle part punch forming of sheet metal goes out right angle fixinig plate 321, right angle fixinig plate 321
It is provided with bolt hole 3211, mica baffle 31 is provided with the bar shaped location hole 311 passed through for sheet metal 32, and sheet metal 32 is kept off across mica
Bar shaped location hole 311 on piece 31 is positioned, and is positioned without using other additional positioning tools, and production effect is improved
Rate.Right angle fixinig plate 321 is provided with the hole location of alignment bolt hole 3211, and right angle fixinig plate 321 touch mica baffle 31, bolt assembly
33 pass through bolt hole 3211 and hole location to which mica baffle 31 and sheet metal 32 be fixed to each other, solve sheet metal 32 because repeatedly by
Situations such as power or human factor caused looseness fault.Right angle fixinig plate 321 touch mica baffle 31 and also plays positioning action,
Keep the distance between the front end of two sheet metals 32 and mica baffle 31 identical, solves and length easily occur not in the prior art
One, upper and lower defective mounting different, angle is different, improves the qualification rate of product size.The bonding of mica baffle 31 or clamping are solid
It is fixed to each other due to aluminum shell 1 or mica baffle 31 with resistor assembly 2,32 rear end electric connection resistance component 2 of sheet metal, gold
Belong to 32 front end of piece and is provided with wiring hole.
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.
