Abstract
The utility model discloses a converter fan pivot formula device utilizes fan guard installation fan and switching PCB board to constitute the fan subassembly, and the fan subassembly passes through fan guard pivot hole and clamps in the inboard pivot of converter casing, can expose the fan supply socket on the switching PCB board completely outside after the fan subassembly is rotatory to be opened, and the plug and the assembly of the fan power cord plug of being convenient for and dismantle the fan, have effectively solved the problem of the narrow and small fan power cord plug of converter casing inner space difficulty.
Description
Technical Field
The utility model relates to a fan installation of converter, in particular to converter fan pivot formula device.
Background
The existing installation mode of the frequency converter fan is that a fan power socket is welded on a PCB inside the frequency converter, a power line plug is connected with the tail end of a fan power line in a crimping mode, and when the internal space of the frequency converter is narrow, the fan power line plug is difficult to assemble. The frequency converter fan is indispensable as the heat dissipation of power device, and also needs convenient operation as wearing parts maintenance change simultaneously, consequently, picks up the fan fast and assembles equally important.
Disclosure of Invention
The utility model discloses the above-mentioned problem to exist among the prior art provides a converter fan pivot formula device for converter assembly, and its technical problem that solves lies in, and fan power cord plug connection is convenient, quick assembly disassembly fan.
The to-be-solved technical problem of the utility model is to utilize fan guard assembly fan and switching PCB board to constitute the fan subassembly, two elasticity pivot holes about the fan subassembly passes through the fan guard, clamp in two pivots about the converter casing inboard, can expose the fan supply socket on the switching PCB board completely outside after the fan subassembly is rotatory to be opened, the plug of the fan power cord plug of being convenient for, and then the installation with tear open and get the fan.
The utility model discloses the technical problem that further solve is that two fan trip in diagonal angle of fan guard directly clamp the fan fixedly, than fix with screw convenient and fast.
The utility model discloses the technical problem that still further solve lies in that two PCB board trip of fan guard are fixed with the direct clamping of switching PCB board.
Adopt the utility model discloses a converter fan pivot formula device when rotating and opening this door of fan guard and integrative fan subassembly of fan, can pull out and insert fan power cord plug on the switching PCB board, also can take off fan and switching PCB board, and easy operation is convenient, does not receive converter casing inner space restriction.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a three-dimensional exploded view of the rotary shaft device of the frequency converter blower of the present invention.
Detailed Description
Fig. 1 shows the three-dimensional exploded view of the revolving shaft device of the frequency converter blower of the present invention, the blower assembly part and the frequency converter casing 2 are separated to show the relationship between the connection of the revolving shaft, and the frequency converter casing 2 and the blower cover 4 are respectively injection molded, so that the present invention is suitable for the small plastic shell frequency converter below eleven kw. The inner rotating shaft 21 of the frequency converter shell 2 can be a metal insert; the fan cover 4 is provided with a grid for ventilating the axial flow fan 3, the rotating shaft hole 43 is matched with the inner rotating shaft 21 by using the elasticity of plastics, and the fan cover 4 further comprises two fan clamping hooks 41 at opposite angles and two PCB clamping hooks 42. The size of the fan hook 41 is determined by the flange of the shell of the fan 3, and the size of the PCB hook 42 is also determined by the thickness of the PCB.
In the blower assembly part of FIG. 1, a blower power line 11 is welded on a frequency converter PCB board 1, and the tail end of the blower power line 11 is crimped with a power line plug 12; a fan power socket 51 is welded on the switching PCB 5, and the switching PCB 5 is clamped on the PCB clamping hook 42.
The frequency converter of the preferred embodiment of the present invention is only described above, and all the equivalent changes or modifications made within the scope of the claims for the small-sized plastic casing chassis of other power electronic devices, including the installation in the wall hanging or electrical cabinet, should be included in the protection scope of the present invention.
