Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
Referring to fig. 1-4, in an embodiment of the present utility model, an insulation supporting block for a fan-shaped resistor frame includes an insulation board 1, a plurality of support columns 2 and a plurality of insulators 3, wherein the plurality of support columns 2 are arranged on one side of the insulation board 1, and the plurality of insulators 3 are arranged on one side of the insulation board 1 away from the support columns 2.
Referring to fig. 3 and 4, the insulating support blocks are uniformly arranged on the inner and outer arc frame plates of the fan-shaped resistor frame, and screw holes are formed in the bottom of the insulator 3 and can be fixed on the arc frame plates through screws. When the resistance belt is fixed, a through hole can be formed in the bending surface of the resistance belt, the through hole penetrates through the support column 2 on the insulation support block, and as the surface of the resistance belt is pressed with the reinforcing ribs, the shape of the resistance belt is kept at the non-bending position through the reinforcing ribs, the resistance belt automatically forms constraint after sequentially penetrating through the support columns on the inner arc-shaped frame plate and the outer arc-shaped frame plate, and finally, the position fixing of the resistance belt is realized.
Referring to fig. 1, a plurality of groups of support columns 2 are arranged on an insulating plate 1 along the length direction, so that the number of through holes penetrating through a curved surface of a resistor belt can be increased, and the stability of the resistor belt after assembly is improved; each group of support columns 2 is at least provided with one in the width direction of the insulating plate 1, and the number of the support columns 2 on the insulating support blocks positioned at the inner arc-shaped frame plates is larger than the number of the support columns 2 on the insulating support blocks positioned at the outer arc-shaped frame plates so as to ensure that the resistor strip is integrally in a fan-shaped structure after being formed.
The insulating board 1 is a polyether-ether-ketone resin modified board, and the brand of the modified polyether-ether-ketone resin is 8200GF30 (glass fiber content is 30%). Since the resistance belt emits a large amount of heat in the working state, the insulating plate 1 is required to have high temperature resistance, and the insulating plate 1 is required to have an insulating function, the insulating plate 1 is made of a polyether-ether-ketone resin modified material. The polyether-ether-ketone resin modified material is a high-temperature resistant nonmetallic material, can resist the temperature of more than 260 ℃, has good insulating property, and also has certain strength to support the resistance belt.
The support column 2 is cylindrical metal pole, and the one end of support column 2 is inlayed and is fixed in inside the insulation board 1. The polyether-ether-ketone resin modified material is a thermosetting material, and the tooth grooves are formed in the support columns 2 made of a metal material, so that the tooth groove ends of the support columns 2 are combined with the insulating plate 1 in a softened state, and the embedding is realized after the insulating plate 1 is solidified. The support column 2 can be tightly connected with the insulating plate 1 in the embedding way, and the support column has high support strength.
In one embodiment, as shown in fig. 1, a section of the support column 2 near the insulating plate 1 protrudes outwards in the radial direction to form a protruding portion 21, and the diameter of the protruding portion 21 is larger than the diameter of the through hole formed in the bending portion of the resistor strip, so that the resistor strip can be prevented from contacting the insulating plate 1 due to manufacturing process deviation or poor assembly after the resistor strip is assembled with the support column 2.
In another embodiment, referring to fig. 2, the support columns 2 are tapered transition structures with diameters gradually increasing from top to bottom, and the diameters of the sections of the support columns 2 near the insulating plate 1 are larger than the diameters of the through holes formed in the resistor strips, so that the resistor strips can be prevented from contacting the insulating plate 1.
Referring to fig. 4, a mounting groove 11 is formed on a side of the insulating plate 1 away from the support column 2, and the insulator 3 is embedded in the mounting groove 11. Because the support column 2 and the insulator 3 are simultaneously embedded and fixed in the process by utilizing the thermosetting of the polyether-ether-ketone resin modified material, the insulator 3 is adhered to the inner wall of the mounting groove 11 of the insulating plate 1 through epoxy resin glue. The epoxy resin adhesive can be used for a long time in the environment of 200 ℃, has good high temperature resistance and firm bonding effect.
Furthermore, the insulator 3 adopts alumina ceramic, and the alumina ceramic has better conductivity, mechanical strength and high temperature resistance and has good adhesion with epoxy resin glue.
The foregoing is merely illustrative of the structures of this utility model and various modifications, additions and substitutions for those skilled in the art can be made to the described embodiments without departing from the scope of the utility model or from the scope of the utility model as defined in the accompanying claims.
