Description
Technical field
It the utility model is related to intelligent power and touch block technical field.
Background technology
Intelligent power module is a kind of power drive device for combining power electronics and integrated circuit technique, due to
The advantages such as high integration, high reliability, intelligent power module win increasing market, are particularly suitable for driving the change of motor
Frequency device and various inverters, are frequency conversion meaning speed, metallurgical machinery, electric propulsion, servo-drive and the common village power of frequency-conversion domestic electric appliances
Electronic device.
Conventionally, as the packaged type that power touches block is not perfect enough, reasonable, integration, the peace of product are caused
Full property and reliability are not good enough, and structure is not reasonable, and production cost is high, and installation and maintenance are inconvenient.
Utility model content
In order to solve the above problem existing for existing power module, the utility model provides a kind of reliability rational in infrastructure
High power module.
Used technical solution is the utility model to achieve the above object：A kind of power module, including at least two
Module 2, is connected by copper bar 1 between module 2 fix two-by-two, the insulator 9 of module 2 and 8 top of radiator pass through upper parallels 3
The downside of upper cover plate 4 is installed on disc spring 10, the insulator 9 of module 2 and 8 lower part of radiator are installed on lower cover 6 by lower padding iron 5
Inner side.
The module 2 is additionally provided with side plate 7, and 7 both ends of side plate are connected by positioning pin 14 with upper cover plate 4 and lower cover 6.
The middle part of upper cover plate 2 is equipped with top bolt 12 and compresses revolving part 13, compresses revolving part 13 and is installed on outside the bolt 12 of top.
The power module of the utility model, compact-sized, production cost is low, external connection is simple, easy to safeguard and install, because
And the weight and cost of device are substantially reduced, and multiple module Optional assemblings can be had a safety feature, it is rational in infrastructure, easy to tear open
Unload and install.
