The utility model discloses an advantage: the utility model discloses simple structure, the material is sealed in the installation of being convenient for, makes two pins more convenient between two parties in the casing all around, the pin is difficult for pulling out for a long time inserts the skew of the in -process left and right sides, and whole pleasing to the eye nature and radiating effect are better.
Description
Technical field
The utility model relates to a kind of resistor, particularly a kind of medium voltage frequency converter dedicated resistor.
Background technology
The skeleton of medium voltage frequency converter dedicated resistor did not have position fixing apparatus in the past, it is the sensation fixed position with operative employee, pin only has a solder joint to be connected with skeleton, deviation is obvious up and down to cause the pin of each resistor, cause arcing in order to prevent on skeleton that resistance wire is encountered aluminum hull, need to lay one deck insulating paper at aluminum hull inwall, it is limited due to the locational space of resistor being installed on frequency converter, and be that multiple resistors are laid side by side, if the pin of resistor is not placed in the middle, will cause between resistor and dodge and stitch, surface of shell contact is bad, not only affect outward appearance, and cause radiating effect not good.
Utility model content
The purpose of this utility model is in the time that envelope is expected, position to be difficult for occupying moderate defect in order to solve existing frequency converter dedicated resistor, and a kind of medium voltage frequency converter dedicated resistor proposing.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of medium voltage frequency converter dedicated resistor, comprise the housing of an end opening, in housing, be fixed a skeleton by insulator seal material, on skeleton, be wound around and be combined with resistance wire, symmetrical two pins of welding that coordinate in one end of skeleton, two pins stretch out from the openend of housing, it is characterized in that: on the madial wall of the left and right of described housing, be respectively equipped with a slot, two slots are parallel to each other and opening symmetry relatively, described skeleton is pegged graft and is engaged in the slot of two opposing parallel, two described pins on skeleton are parallel to each other, and two described pins are the center at shell nozzle as an overall co-ordination.
On the basis of technique scheme, can there is following further technical scheme:
Described skeleton is " work " font flat board, and two described pins are symmetrically welded at " work " font flat board the same side with one end.
Each described pin is all coordinated and is welded and fixed by two solder joints with described skeleton.
Described skeleton is pegged graft and is coordinated with slot.
Two symmetrical slot positions of described housing are partial to the same side of housing simultaneously.
The beneficial effects of the utility model: the utility model is simple in structure, are convenient to install envelope material, are provided with slot on housing, are convenient to two pins placed in the middle in housing all around; In the time of two pins and frame welding, be provided with two solder joints, make pin be difficult for left and right skew in long-time plug process, thereby affect overall appearance, make the better heat-radiation effect between many group rheostats.

Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 5, a kind of medium voltage frequency converter dedicated resistor that the utility model provides, comprise the square aluminium casing 1 of an end opening, in housing 1, be fixed a skeleton 2 by insulator seal material, on skeleton 2, be wound around and be combined with resistance wire 4, symmetrical two the sheet type pins 3 of welding that coordinate in one end of skeleton 2, two pins 3 stretch out from the openend of housing 1, and coordinate with outer grafting circle, on the madial wall of the left and right of housing 1, be respectively equipped with two projection 1b, between two projection 1b of every side, form the slot 1a of " recessed " font, two slot 1a are parallel to each other and opening symmetry relatively, described skeleton 2 is pegged graft and is engaged in the slot 1a of two opposing parallel, two described pins 3 on skeleton 2 are parallel to each other, and two described pins 3 are the center at housing 1 opening as an overall co-ordination.
As shown in Figure 1 and Figure 4, on described skeleton 2, be wound around and be combined with resistance wire 4, described skeleton 2 is " work " font flat board, be provided with the 2b that bores a hole under a lead-in wire in one end of " work " font flat board, be provided with at the other end of " work " font flat board the 2a that bores a hole on two lead-in wires, the 2a that bores a hole on two lead-in wires lays respectively at the bottom of two described pins 3, two described pins 3 are symmetrically welded at " work " font flat board the same side with one end, and each described pin 3 is all coordinated and is welded and fixed by two solder joints 5 with described skeleton 2. Front side or the rear side of housing 1 is partial in two symmetrical slot 1a positions of described housing 1 simultaneously, the width of described slot 1a is less times greater than the thickness of described skeleton 2, and described skeleton 2 and slot 1a tight fit, if the front side of two slot 1a deflection housings 1, two described pins 3 that welding is engaged in skeleton 2 the same sides so are just positioned at the rear side of housing 1, vice versa, and front-rear center line between two pins 3 and left and right center line all with front-rear center line and the left and right center superposition of housing 1.
Due to the special mounting requirement of frequency converter dedicated resistor, to lay side by side for many, resistance pin up and down must be placed in the middle, can not have deviation, and this Special aluminium shell of ad hoc meter and resistor core skeleton, make resistance inserted sheet placed in the middle up and down in resistance aluminum hull.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
