Description

Technical Field

[0002] Multilayer mica sheet aluminum shell resistor is a resistor that combines the heat dissipation advantages of aluminum shell and the insulation and heat insulation properties of mica sheet. Multilayer mica sheet aluminum shell resistor has been widely used in many fields due to its excellent performance characteristics. For example, it is used to limit current, divide voltage and load balance in power systems; it is used to adjust the amplitude and frequency of signals in communication equipment; it is used to control current, voltage and power in automotive electronic systems, etc.

[0003] At present, similar products such as aluminum shell resistors mostly use ceramic core rods and single-piece mica sheets as the substrate, which makes the volume of the resistors larger and cannot meet the needs of high-power and small-volume resistors.

The contact between the lower part of the resistor and the assembly surface is not friendly to heat removal and cooling.

[0045] During the assembly of the resistor housing 12, the cover 143 at the bottom of the assembly table 142 is first opened, and then one side of the cover 143 is pressed, and then one side of the cover 143 is stretched open, and a locking assembly is installed at one end of the cover 143, and the locking assembly includes an embedding hook and an embedding port.

The resistor housing 12 is gradually pressed downward until the cooling box 132 is attached to the assembly table 142.

[0046] The specific implementation method is as follows: during operation, when the cooling unit 13 cools down and removes heat, the hot air generated by the operation of the resistor housing 12 is transferred to the cooling plate 136 via the conductive rod 135. At this time, the hot air leaks out through the cooling hole 2 1323 on the cooling box 132, and the surrounding cool air flows in from the cooling hole 3 1324. The movement of the cool air pulls the guide piece 133 and the guide piece 2 134 to rotate, thereby increasing the movement speed of the cool air. At this time, the speed of the hot air leaking out of the cooling hole 1322 increases. When the resistor housing 12 is assembled using the fixed connection unit 14, the conductive rod 135 is aligned with the embedded cavity 1425 and slowly inserted, and the conductive rod 135 is inserted into the conductive cavity 1425. The rod 135 initially presses the slope of the box body 147, and the embedded platform 148 is pressed and displaced into the box body 147, until the through hole 3 1352 and the embedded platform 148 are on the same plane. Under the restoring force of the spiral beryllium copper wire 149, the embedded platform 148 is displaced into the through hole 3 1352, which can restrain the conductive rod 135, and achieve the purpose of assembling the resistor housing 12. During the separation, the cover 143 is opened, and the rotating disk 144 in the assembly chamber 3 1422 and the assembly chamber 4 1424 is rotated until the other end of the protruding resistance platform 1442 is attached to the stop plate 146. At this time, the rotating disk 144 is rotated The movable rod 3 145 pulls the box body 147, and the box body 147 pulls the slope of the embedded platform 148 downward through the stop cavity 1472 and the stop platform 1482, that is, the conductive rod 135 can be pulled out from the assembly platform 142. During the offset vibration period, the vibration of the resistor housing 12 causes the offset platform 1 152 to fluctuate up and down. At this time, the spiral beryllium copper wire 2 153 can offset the vibration of the offset platform 1 152. Through the cooperation of the assembly piece 1 154, the rotating rod 4 1542, the connecting rod 155, the assembly piece 2 156, and the rotating rod 5 1562, the offset platform 1 152 pulls the offset platform 2 157 along the slide. The shift bar 159 slides, and at this time the spiral beryllium copper wire three 158 can offset the vibration of the offset platform two 157. The through hole one 1325 and the through hole two 1326 are used to assemble the offset platform one 152 and the offset platform two 157 respectively. The rotating rod one 1332 and the rotating rod two 1342 are used to assemble the guide piece one 133 and the guide piece two 134. The assembly hole 1362 is used to fix the cooling plate 136 on the conductive rod 135. The heat removal hole 1363 can increase the cooling speed of the cooling plate 136. The through cavity 1423 is used to assemble the rotating rod three 145. The sliding groove 1572 is used to adapt to the spiral beryllium copper wire three 158.
