Description

Converter

This embodiment relates to a converter.

Electrical devices in automobiles generally include engine electrical devices (starter, ignition, charging device) and lighting devices, but recently, as vehicles have become more electronically controlled, most systems, including chassis electrical devices, are becoming electrical and electronic. .

Various electrical equipment such as lamps, audio, heaters, and air conditioners installed in cars are supplied with power from the battery when the car is stopped, and from the generator when running. At this time, the normal power voltage is used to generate power in the 14V power system. Capacity is being used.

Recently, with the development of the information technology industry, various new technologies (motor-type power steering, Internet, etc.) aimed at increasing the convenience of automobiles have been incorporated into vehicles, and the development of new technologies that can utilize current automobile systems to the fullest extent will continue in the future. It is a prospect.

Hybrid electric vehicles (HEV), regardless of soft or hard type, are equipped with a DC-DC converter (Low Voltage DC-DC Converter) to supply electric loads (12V). In addition, the DCDC converter, which acts as a generator (alternator) in general gasoline vehicles, lowers the high voltage of the main battery (usually a high-voltage battery of 144V or higher) and supplies 12V voltage for electrical loads.

A DC-DC converter is an electronic circuit device that converts direct current power of a certain voltage into direct current power of a different voltage, and is used in various fields such as television sets and automotive electronics.

One or more electronic components are placed inside the converter. there is. Examples of electronic components may include transformers for voltage regulation and inductors for obtaining inductance.

The electronic component may be coupled to a printed circuit board or the inner surface of a housing. At this time, the electronic components can be combined with the above-described components through a bracket. The bracket may include a body that surrounds the outer surface of the electronic component, and an extension portion that extends to the outside of the body and is coupled to a printed circuit board or housing. A hole is formed in the extension portion, and a hole is also formed in the printed circuit board or housing, so that the screw can be coupled through the holes. Because of this, the electronic components combined with the bracket can be firmly fixed within the housing.

However, according to the above structure, a plurality of holes into which the screw is inserted must be aligned coaxially, which has the disadvantage that the manufacturing process is cumbersome. In addition, when multiple screw holes are placed on a single bracket, the positions of other screw holes may change when a screw is coupled to one screw hole, which reduces production efficiency because separate manual work for alignment is required. .

The present invention aims to provide a converter that can improve production efficiency by improving the fastening structure between parts.

The converter according to this embodiment includes a housing in which an internal space is formed; a base disposed on the inner surface of the housing and including a second coupling hole; Electronic components disposed on the upper side of the base; a bracket disposed on an upper side of the electronic component and including a first coupling hole disposed to face the second coupling hole; a guide that is at least partially accommodated in the first coupling hole and the second coupling hole and has a through hole formed therein, penetrating from the upper surface to the lower surface; and a screw that is at least partially accommodated in the through hole and screwed into the second coupling hole.

In this embodiment, when the bracket and the base are combined, the screws are aligned through a guide, so there is an advantage that the worker can more easily assemble the parts.

In other words, since the straightness of the screw is guaranteed through a guide when the screw is screwed into the coupling hole, the alignment adjustment process for separate screw coupling is omitted, and work efficiency can be improved.

In addition, in the case where multiple screw connection areas are arranged, the plurality of parts are primarily fixed through a guide before screw connection, so the alignment of other areas can be maintained even when screw connection is performed in one area. There is.
