Description

A kind of electric power electronic module securing member

Technical field

This utility model belongs to semi-conductor power module technical field, is specifically related to the securing member of a kind of electric power electronic module。

Background technology

At present, in the assembling of power electronics compression joint type module, the element such as chip, electrode and DBC is to be press-fited by screw by securing member to combine。Securing member is gluing to be connected into an entirety by spring bearer plate, round clamp, insulation board by 502, and spring bearer plate, round clamp, insulation board etc. exist in the process being mutually bonded and are susceptible to crooked, the defect such as be scattered；And 502 colloid when module works, can volatilize material that module chip is influential, reduces module quality, affects module service life。It addition, in order to keep screw and element insulating, it is necessary to overlapping an insulated sleeve on screw, in assembling process, due to assembly error or misoperation, this insulated sleeve is easily damaged and loses efficacy。

To sum up, the securing member of existing electric power electronic module, there is part many and scattered, part combination is complicated, the shortcomings such as fastening effect is not good。In order to ensure the assembling effect of power electronics compression joint type module, it is those skilled in the art's one of technical barriers of needing thinking that existing securing member is improved。

Utility model content

Technical problem to be solved in the utility model is to provide a kind of electric power electronic module securing member for above-mentioned prior art, simplifies assembly operation, improves packaging efficiency。

The technical scheme in the invention for solving the above technical problem is: a kind of electric power electronic module securing member, including elastic plate, round clamp and insulation board, described insulation board is arranged below the insulated sleeve for insulated screw, described round clamp and elastic plate can shirk clamping respectively with insulation board, and the end face of elastic plate can correspondence cover on round clamp。

Specifically, the relevant position on described insulation board is provided with the circular screens for setting circle pressing plate, and described circular screens is to be surrounded by the buckle of 2 or more than 2。Relevant position on described insulation board is provided with the buckle for positioning elastic plate。

Relatively it is reasonable that, the position of the buckle for fixing elastic plate is higher than the buckle for fixing round clamp。

Preferably, described insulation board and insulated sleeve are PPS integrated injection molding part, and structural strength is higher, and insulation effect is better。

Compared with prior art, the utility model has the advantage of: round clamp and elastic plate are set to the mode of clamping with the connection of insulation board respectively, make the assembly operation between each part of securing member easier and part location is reliable, the packaging efficiency of product is greatly improved, improves the competitiveness of product in market。

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail。

If Fig. 1 is to shown in 7, electric power electronic module securing member in the present embodiment, including elastic plate 1, a pair round clamp 2 and insulation board 3, described insulation board 3 is arranged below the insulated sleeve 4 for insulated screw, insulation board 3 and insulated sleeve 4 are PPS integrated injection molding part, structural strength is higher, and insulation effect is better。Round clamp 2 and elastic plate 1 can shirk clamping respectively with insulation board 3, and in assembled state, two end faces of elastic plate 1 can correspondence cover on two round clamps 2。

Relevant position on insulation board 3 is provided with the circular screens a for setting circle pressing plate 2, and circular screens a is surrounded by 3 buckles 5。It addition, the relevant position on insulation board 3 is relatively set with the buckle 5 for positioning elastic plate。Position for fixing the buckle of elastic plate is higher than the buckle for fixing round clamp。

Round clamp, elastic plate are set to clamping with the connected mode of insulation board by the securing member of said structure respectively, simplify assembling, location reliably, the packaging efficiency of product is greatly improved, improve the competitiveness of product in market。

In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, and all should fall within this utility model scope of the claims。
