One convex block and the second convex block make shell and the bigger suction of thermally conductive gel contact surface by the second convex block on the outside of being staggered in shell
It receives internal heat faster, increases the contact area of shell and outside air by the first convex block, distribute the heat on shell more
Fastly.
The bottom plate two sides are arranged multiple mounting holes, and the mounting hole passes through the mounting hole of setting at U-shaped, convenient
Resistor and circuit board are fixed with bolt, U-shaped mounting hole is set, on circuit boards in the slightly crooked situation of the precision of screw hole
Also it can make resistor installation on circuit boards, it is quick and easy for installation.
Plug is arranged in the wire lug end, and location hole is arranged in the middle part of the plug, facilitates connector lug and other electricity
Subcomponent is electrically connected, while avoiding connector lug from falling off because jolting or shaking by location hole.
The filler is heat dissipation cotton, accelerates the shaking that internal material is avoided while heat dissipation.
Working principle: when resistor at work, polyethylene layer play to resistor core wrap up insulate while subtract
The shaking of few resistor core, beryllium oxide ceramics layer have good thermal conductivity, can be quickly by resistor core by beryllium oxide heat-conducting layer
The heat derives of generation, filler layer, thermally conductive gel and shell are while guaranteeing resistor structure integrality in protective shell body
Resistor core, and there is good heat-conducting effect, the heat generated when resistor being made to work is discharged as early as possible, avoids high temperature to resistance
The work of device has an impact.
It is novel in design the utility model has the following beneficial effects: the utility model structure is simple, by by outside resistor core layer by layer
