Description

Connector module and converter including the same {Connector module and Converter having the same}

This embodiment relates to a connector module and a converter including the same.

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.

The converter may be shaped by a housing. Additionally, a connector module for electrical connection to the battery or load may be disposed on the outer surface of the housing. When the connector module is combined with an external terminal, the converter can receive power from the battery or apply the converted power to the load.

The connector module is provided with a plurality of connector terminals to each be connected to a plurality of external terminals having different power values. For example, there may be three external terminals and three connector terminals. Since each external terminal must be connected to a connector terminal with the same power value, operator caution is required during the converter manufacturing process.

The present invention was proposed to improve the above problems, and its object is to provide a connector module that can increase work efficiency by easily distinguishing terminals with different power values, and a converter including the same.

The connector module according to this embodiment includes a frame; a plurality of coupling pins disposed on the frame; a plurality of terminals provided in plural numbers corresponding to the number of the coupling pins, one end of which is coupled to the coupling pins; and a plurality of terminals corresponding to the number of the coupling pins, one end of which is coupled to the coupling pins. The cross-sectional areas of the plurality of coupling pins have different sizes.

According to the above configuration in this embodiment, there is an advantage in that misassembly and defects between parts can be prevented by forming receiving portions and coupling holes of different sizes between a plurality of connectors and a plurality of terminals.

In particular, since power of different sizes is applied to a plurality of connectors and terminals, there is an advantage in preventing an electrical short from occurring within the converter.

In addition, workers can assemble terminals and connectors to correspond to each other without separate confirmation, which has the advantage of reducing the number of working hours and increasing production efficiency.

Figure 7 is a flowchart showing the manufacturing process of a connector module according to an embodiment of the present invention.

Referring to Figures 2 to 7, first, the first to third coupling pins (111, 131, 151) have the terminals (110, 130, 150) through the first to third coupling holes (112a, 132a, 152a). are combined. And, the first to third terminals 120, 140, and 160 are disposed on the upper side of the terminals 110, 130, and 150. This is because the first to third coupling pins (111, 131, 151) penetrate the fourth to sixth coupling holes (121a, 141a, 161a) formed in the first to third terminals (120, 140, 160), respectively. It can be done.

Accordingly, the terminals 110, 130, and 150 and the terminals 120, 140, and 160 may be electrically connected to each other. And, in order to maintain the coupled state of both components, first to third washers (125, 145, 165) and first to third nuts (126, 146, 166) can each be combined. That is, when the terminals 120, 140, and 160 are coupled to the terminals (110, 130, and 150), the washers (125, 145, and 165) and the nuts (126, 146, and 166) are connected to the coupling pin ( 111, 131, and 151, it is possible to prevent the terminals 110, 130, 150 and the terminals 120, 140, and 160 from being separated to the outside. The washers (125, 145, 165) and the nuts (126, 146, 166) may be screwed to the coupling pins (111, 131, 151).

Meanwhile, the connector module 50 according to this embodiment may have a structure to prevent terminals with different power values from being connected to each other during the manufacturing process.

In detail, the cross-sectional areas of the first coupling pin 111, the second coupling pin 131, and the third coupling pin 151 may be different from each other. Due to this, the first to third coupling holes (112a, 132a, 152a) and the fourth to sixth coupling holes (121a, 141a, 161a) are coupled to the first to third coupling pins (111, 131, 151). The cross-sectional area may be formed to correspond to the cross-sectional area of the coupling pin to be coupled.

For example, the cross-sectional area of the first coupling pin 111 may be larger than that of the third coupling pin 151 and smaller than the cross-sectional area of the second coupling pin 131. Accordingly, the first terminal 110 in which the first coupling hole 112a coupled to the first coupling pin 111 is formed, and the first terminal 120 in which the fourth coupling hole 121a is formed, are connected to the second coupling pin 111. It can be prevented from being coupled to the coupling pin 131. Likewise, the third terminal 150 formed with the third coupling hole 152a coupled to the third coupling pin 151 and the third terminal 160 formed with the sixth coupling hole 161a are each connected to the first coupling pin 151. It can be prevented from being coupled to (111) and the second coupling pin (131). Accordingly, the terminal 101 and the terminals 120, 140, and 160 can be coupled only to the set coupling pins, thereby preventing short-circuiting with components in which power supplies of different sizes are formed.

In addition, since the cross-sectional areas of the first to third coupling pins 111, 131, and 151 are different from each other, the cross-sectional areas of the holes formed in the washers 125, 145, and 165 and the nuts 126, 146, and 166 are also coupled. Of course, it is formed to correspond to the cross-sectional area of the pins 111, 131, and 151.

Furthermore, the cross-sectional areas of the receiving portions 66, 67, and 68 according to embodiments of the present invention may be formed differently. In addition, the cross-sectional areas of the regions disposed within the receiving portions 66, 67, and 68 of the terminals 120, 140, and 160, that is, the first to third coupling portions 121, 141, and 161, may also be formed differently from each other. You can. In other words, the cross-sectional areas of the plurality of receiving portions 66, 67, and 68 may be formed differently to correspond to the plurality of coupling portions 121, 141, and 161 having different cross-sectional areas.

For example, the cross-sectional area of the second receiving portion 67 to which the second coupling portion 141 is coupled may be formed to be the largest. In addition, the cross-sectional area of the first accommodating part 66 to which the first coupling part 121 is coupled is formed to be smaller than the cross-sectional area of the second accommodating part 67, and the third accommodating part 161 to which the third coupling part 161 is coupled. It may be formed to be larger than the cross-sectional area of the receiving portion 68.

Accordingly, the first terminal 120 can be prevented from being coupled to the third receiving portion 68. Also, the second terminal 140 can be prevented from being coupled to the first accommodating part 66 and the third accommodating part 68.

Through the above configuration, the first terminal 120 can be prevented from being coupled to the second receiving portion 67 by the cross-sectional area of the second coupling pin 131. In addition, due to the difference in cross-sectional area of the third accommodating part 68 and the first coupling part 121, the first terminal 120 can be prevented from being coupled to the third accommodating part 68. there is.

In addition, due to the difference in cross-sectional area of the first accommodating part 66 and the second coupling part 141, the second terminal 140 can be prevented from being coupled to the first accommodating part 66. there is. In addition, due to the difference in cross-sectional area of the third accommodating part 68 and the second coupling part 141, the second terminal 140 can be prevented from being coupled to the third accommodating part 68. there is.

Furthermore, due to the difference in cross-sectional area of the first coupling pin 111 and the sixth coupling hole 161a, the third terminal 160 can be prevented from being coupled to the first receiving portion 66. there is. In addition, due to the difference in cross-sectional area of the second coupling pin 131 and the sixth coupling hole 161a, the third terminal 160 can be prevented from being coupled to the second receiving portion 67. there is.

According to the above configuration, there is an advantage in that misassembly and defects between parts can be prevented by forming receiving portions and coupling holes of different sizes between a plurality of connectors and a plurality of terminals.

In particular, since power of different sizes is applied to a plurality of connectors and terminals, there is an advantage in preventing an electrical short from occurring within the converter.

In addition, workers can assemble terminals and connectors to correspond to each other without separate confirmation, which has the advantage of reducing the number of working hours and increasing production efficiency.
