Abstract
The utility model discloses a converter fan cut straightly formula device for converter installation utilizes two mounting hole installation switching PCB boards of fan to constitute fan subassembly, when assembly converter fan and power are connected, fan subassembly includes welded fan power contact pin (51) on switching PCB board (5), directly pushes away in converter casing (2) and inserts welded fan supply socket (11) on converter PCB board (1). During the assembly of the fan assembly, the fan assembly is directly pushed into the frequency converter shell, so that the problem that the power line plug of the fan is difficult to assemble due to the narrow inner space of the frequency converter shell is effectively solved.
Description
Technical Field
The utility model relates to a fan installation of converter relates to a converter fan cut straightly 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 cut straightly formula device for converter installation, and its technical problem that solves lies in, and converter casing inner space leads to the narrow and small problem of getting the difficulty of fan power cord plug dress.
The to-be-solved technical problem of the utility model is to utilize two mounting holes on fan (3) and the fan casing, install switching PCB board (5) into fan subassembly with two screws (6), when assembly converter fan and power are connected, the fan subassembly includes welded fan power contact pin (51) on switching PCB board (5), directly pushes away in converter casing (2) and inserts welded fan supply socket (11) on converter PCB board (1).
The utility model discloses the technical problem that further solve is realized like this: a guide hole (21) is formed in the frequency converter shell (2), and the guide hole (21) is accurately positioned corresponding to a fan power socket (11) on the frequency converter PCB (1); chutes (22) are arranged on two sides in the frequency converter shell (2) to accurately guide two sides of the switching PCB (5); the bottom of the frequency converter casing (2) is provided with a fan positioning piece (4) for positioning the fan assembly and shielding wind.
The utility model discloses the technical problem that still further solve lies in direct welding fan power cord (31) on switching PCB board (5).
Adopt the utility model discloses a fan cut straightly formula device, take out as needs during the fan subassembly, then take off the vertical whole fan subassembly that draws out of fan setting element (4) for welded fan power supply contact pin (51) breaks away from fan supply socket (11) on converter PCB board (1) on switching PCB board (5), and easy operation is convenient, does not receive converter casing (2) inner space restriction.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings:
fig. 1 is a cross-sectional view in the axial direction of a fan for mounting a frequency converter in the prior art.
Figure 2 is the utility model discloses a converter fan cut straightly formula device side partial cross-section for converter installation.
FIG. 3 is a cross-sectional view of the fan of the frequency converter fan in-line device shown in FIG. 2 in the axial direction.
Detailed Description
For a better understanding of the present invention's improvement over the prior art, reference will be made to the prior art as referred to in the background section in conjunction with fig. 1 before a detailed description of the embodiments of the present invention is given. Fig. 1 shows that a fan power socket 11 is welded on a frequency converter PCB board 1, and a power plug 32 is crimped at the end of a fan power line 31, and the assembly method has the disadvantage that when the internal space of the frequency converter is narrow, the fan power plug 32 is difficult to plug.
As shown in fig. 2, two mounting holes are formed in a casing of a frequency converter fan 3, a switching PCB 5 is mounted by two screws 6 to form a fan assembly, and the fan assembly is directly pushed into the frequency converter casing 2 during assembly, wherein an arrow indicates the pushing direction of the fan assembly.
In a preferred embodiment, fig. 3 shows that the fan power line 31 is directly soldered on the adaptor PCB 5, the fan power pin 51 is soldered on the adaptor PCB 5, and the fan power pin 51 is inserted into the fan power socket 11 to complete the fan power line connection during the assembly of the frequency converter.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can apply various equivalent changes and modifications based on the above embodiment, and all equivalent changes and modifications within the scope of the appended claims should be covered by the present invention.
