Abstract
The utility model relates to a power electronic module's package assembly, including shell, bottom plate, the corresponding position of shell and bottom plate is provided with shell mounting hole and gasket -mounted hole respectively, still including running through simultaneously the downthehole pressure -containing parts of shell mounting hole and gasket -mounted, pressure -containing parts's front end be with the fixed first step of gasket -mounted hole crimping, be after the first step with the shell mounting hole corresponds complex second step, the external diameter of second step is less than the aperture of shell mounting hole, transition between first step and second step constitutes that to prevent that the second step from stretching into the gasket -mounted downthehole spacing. Prevent that the module shell from receiving the setting pressure and damaged condition emergence when the installation is used to the module, and then protected the components and parts combination in the module, ensure the service property (quality) of module.
Description
Technical field
The utility model belongs to semi-conductor power module technical field, is specifically related to a kind of package assembly of electric power electronic module.
Background technology
Electric power electronic module, mainly comprises shell and base plate, and shell and base plate surround module internal cavity, arranges electronic devices and components combination, also need gel filled in module internal cavity in module internal cavity.At present, electric power electronic module needs when assembling to scribble fluid sealant around the installing hole between shell and base plate.When module and its relevant device are installed, bear setting pressure by being injected into metal inserted piece integrally with module housing, during operation, if the setting pressure be applied on metal inserted piece is excessive, then be easy to cause the stressed extruding module housing of mold insert, even cause module housing to produce to break, cause the gel-filled spilling of inside modules, make Module Fail.
Utility model content
Technical problem to be solved in the utility model is the package assembly providing a kind of electric power electronic module for above-mentioned prior art; simplify assembly operation; avoid setting pressure to act on module housing, protection module shell, prevent the destruction caused because assembly operation is improper module.
The technical scheme in the invention for solving the above technical problem is: a kind of package assembly of electric power electronic module, comprise shell, base plate, the corresponding position of described shell and base plate is respectively arranged with shell installing hole and base plate installing hole, also comprise be applied in simultaneously corresponding become pressure part in the described shell installing hole of a group and base plate installing hole, the front end of described pressure part is crimp fixing first step with described base plate installing hole, it is the second step with described shell installing hole corresponding matching after described first step, the external diameter of described second step is less than the aperture of shell installing hole, transition between described first step and second step forms prevent second step from stretching in base plate installing hole spacing.
Preferably, described first step outer peripheral face forming boss that can be inconsistent with base plate installing hole, thus guarantee that the first step being positioned at pressure-bearing platform front end reliably crimps with base plate installing hole, can not come off when transporting and have enough to meet the need.
In order to ensure module with relevant device install be connected time setting pressure only act on pressure part and base plate; and shell is not subject to related pressure; the external diameter of second step is arranged to the mode being less than shell installing hole; make between shell and pressure part, to leave enough gaps; effectively prevent module housing to occur because of stressed destroying; and then guarantee that protecting glue that inside modules is noted is unlikely to because shell destroys and overflows; the components and parts of module internal cavity are combined with outside effectively isolated; the combination of protection components and parts, guarantees the serviceability of module.
Compared with prior art; the utility model has the advantage of: the package assembly providing a kind of electric power electronic module; prevent module housing to be subject to the situation generation of setting pressure and breakage when module uses and installs, and then protect the components and parts combination in module, guarantee the service quality of module.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the utility model embodiment housing;
Fig. 2 is the structural representation of base plate in the utility model embodiment;
Fig. 3 is the cutaway view of pressure part in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the package assembly of the electric power electronic module in the present embodiment, comprise shell 1, base plate 2, the corresponding position of described shell 1 and base plate 2 is respectively arranged with shell installing hole 1.1 and base plate installing hole 2.1, also comprise be applied in simultaneously corresponding become pressure part 3 in the shell installing hole 1.1 of a group and base plate installing hole 2.1, the front end of described pressure part 3 is crimp fixing first step 3.1 with base plate installing hole 2.1, be the second step 3.2 with described shell installing hole 1.1 corresponding matching after described first step 3.1, the external diameter of described second step 3.2 is less than the aperture of shell installing hole 1.1 to make to form enough spaces between shell 1 and pressure part 3, prevent module housing 1 from bearing setting pressure.Transition formation between first step 3.1 and second step 3.2 prevents second step 3.2 from stretching into spacing 3.4 in base plate installing hole 2.1.First step 3.1 outer peripheral face forms can be inconsistent with base plate installing hole 2.1 boss 3.3, make first step 3.1 and base plate installing hole 2.1 form interference fit, realize pressure part 3 and crimp with the reliable of base plate 1.
The package assembly of the electric power electronic module of said structure, can effectively prevent module housing to be subject to the situation generation of setting pressure and breakage when assembling, and then protects the components and parts combination in module, guarantees the service quality of module.
In addition to the implementation, the utility model also includes other execution modes, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection range that all should fall into the utility model claim.
Claims (2)
1. the package assembly of an electric power electronic module, comprise shell, base plate, the corresponding position of described shell and base plate is respectively arranged with shell installing hole and base plate installing hole, it is characterized in that: also comprise be applied in simultaneously corresponding become pressure part in the described shell installing hole of a group and base plate installing hole, the front end of described pressure part is crimp fixing first step with described base plate installing hole, it is the second step with described shell installing hole corresponding matching after described first step, the external diameter of described second step is less than the aperture of shell installing hole, transition between described first step and second step forms prevent second step from stretching in base plate installing hole spacing.
2. the package assembly of electric power electronic module according to claim 1, is characterized in that: described first step outer peripheral face forms boss that can be inconsistent with base plate installing hole.
