Description

Block for vehicle

The present invention relates to an automobile block that can be used in automobiles.

Various blocks can be used in automobiles to connect between the load and the power source. These blocks contain components such as relays, current sensors, and precharge relays, so circuits can be constructed using wires or bus bars.

Circuit connections between various parts used in automotive blocks can be made by wires, bus bars, etc. Therefore, inside the block, wires, bus bars, etc. are intricately intertwined, taking up a lot of space. In order to secure the insulation distance between the wires and bus bars, a lot of space is required, which can increase the size of the entire automobile block.

Due to this problem, when designing a block for an automobile that must be installed in a given space, securing the insulation distance between wires and bus bars becomes a very important part of the design of the block.

Components such as relays and current sensors used in automobile blocks require external signal connections. For this signal connection, separate connectors and wires are used. Therefore, there is a problem in that the process of combining signal connection connectors to components and mounting these components back on the base of the block takes a long time to assemble the entire block.

In addition, if the operator is not skilled in the process of connecting the connector and the parts, problems such as the block not operating due to incorrect assembly may occur.

The purpose of the present invention is to solve the problems described above and to minimize the number of wires and bus bars located inside the automobile block.

The purpose of the present invention is to simplify the process of installing parts used in automobile blocks.

The purpose of the present invention is to minimize the number of wires and bus bars located adjacent to other parts inside the automobile block.

The purpose of the present invention is to prevent incorrect assembly of parts used in automobile blocks.

According to the features of the present invention for achieving the above-mentioned object, the automobile block of the present invention is provided with a base having a component seating portion on which the component is mounted, and the component seating portion for signal connection with the component. It may include a connector base, a signal bus bar integrally installed within the base to transmit signals between the outside and the components, and a power bus bar mounted on the base and forming a circuit between the components.

The connector stand is formed integrally with the base and may include a connector housing constituting the exterior, and a component connection terminal portion located inside the connector housing and constituting one side of the signal bus bar.

The inlet of the connector housing may be provided with a terminal slit into which the signal terminal of the component is inserted.

The terminal slit may be cross-shaped.

The signal terminal of the component may be inserted through a relatively short portion of the terminal slit.

The signal bus bar includes a bus bar body portion integrally located within the base, a component connection terminal portion located at one end of the bus bar body portion and located within the connector table and electrically connected to the component, and the other end of the bus bar body portion. It is located at and exposed to one edge of the base and may include an external connection terminal portion electrically connected to the outside of the block.

The component connection terminal may be a fork terminal.

The external connection terminal may be a terminal of a connector installed on the external connection part of the base.

The bus bar body part is located within the bus bar bead formed on the base and can be integrated with the base by insert injection molding.

The bus bar body portion may extend from the connector stand to an external connection portion at the edge of the base while being bent in multiple numbers.

The component is a relay, including a relay body with connection electrodes, a mounting piece provided on the lower part of the relay body for mounting on the base, and a mounting piece provided on one outer surface of the relay body and combined with the connector base to electrically connect. It may include a connector unit that performs.

The connector portion may include a connector housing that forms an exterior and whose interior space is open toward the surface of the base, and a signal terminal provided inside the connector housing and coupled to the component connection terminal portion.

A cover may be further provided to shield the components installed on the base.

The cover is comprised of a cover side wall surrounding an edge of the cover plate, and on the cover side wall, a fastening piece hooked on a fastening jaw provided on the base can be extended to be elastically deformable.

The automobile block according to the present invention can have at least one of the following effects.

In the present invention, the components used in the block are integrated into the base to connect signals to the outside. In other words, some of the bus bars were injection molded so that they were integrated into the base. Therefore, the bus bars and wires for signal connections are not exposed, which has the effect of minimizing the number of bus bars and wires that must be separately assembled when manufacturing automobile blocks.

In the present invention, the connection between the components inside the block and the components for signal connection to the outside can be made automatically by installing the corresponding components on the base. Therefore, the process of assembling automobile blocks has the effect of being relatively simplified.

In the present invention, for example, a relay, which is a component installed inside the block, and a connector for signal connection to the outside can be electrically connected by a plurality of bus bars integrally installed on the base. Here, these multiple bus bars are installed integrally in the base, so securing the insulation distance between them and from other surrounding components can be eliminated or minimized. Therefore, it is relatively easy to secure the insulation distance between components installed inside the block, which has the effect of increasing design freedom.

In the present invention, some of the bus bars are already integrally fixed to the base, and signal connections can be made accurately by simply mounting the components. In particular, when mounting a part at a specific location, the connector part of the part and the connector stand of the base are directly connected, so the operator can easily check the mounting position, which can also have the effect of preventing misassembly of the part.

1 shows a block for an automobile according to an embodiment of the present invention. The automobile block of this embodiment may have various parts mounted on the base 10. The base 10 may be made of an insulating material. The base 10 may be made of insulating synthetic resin. The base 10 may include a base plate 12 and a base side wall 14 provided around an edge of the base plate 12.

The base plate 12 may be approximately rectangular when viewed in plan view. The base plate 12 does not necessarily have to be rectangular. In the illustrated embodiment, the base plate 12 is a rectangle extending in one direction when viewed in plan view. The base plate 12 may have different heights depending on the area. There are areas on the base plate 12 divided by partition walls 16, and these areas may have different heights or shapes. For example, there may be an open space at the bottom of the base plate 12, and by forming this space, the upper surface of the corresponding area of the base plate 12 may protrude relative to the surrounding area. As an example of such an area, as can be seen in FIG. 3, there may be a portion where the resistor 34, which will be described below, is located.

The base side wall 14 may be formed around an edge of the base plate 12. However, the base side wall 14 does not have to be formed on the entire edge of the base plate 12. The base side wall 14 may have different heights depending on its location. On the outer surface of the base side wall 14, fastening protrusions 14' are protruded at a number of locations. The fastening piece 46 of the cover 40, which will be described below, can be hung on the fastening jaw 14'.

There may be a plurality of partition walls 16 on the base plate 12. The partition wall 16 may have different heights depending on its location and function. As can be seen in FIG. 4, there may be partition walls 16 at multiple locations on the base plate 12. The partition wall 16 may function to secure an insulating distance while dividing the area where the components are placed from the surrounding area.

There may be mounting pieces 18 at four corners of the base plate 12. The mounting piece 18 is for mounting the base 10 to a fixed part. The mounting piece 18 does not necessarily have to be at a corner of the base plate 12, but may be located adjacent to the corner.

There may be component seating portions 20 at multiple locations on the base plate 12. The component seating portion 20 shown in FIG. 4 is where the relay 30, which will be described below, is seated. The component seating portion 20 may be partitioned from its surroundings by the partition wall 16. The partition wall 16 partitions the component mounting portion 20 from the surrounding area, but does not completely partition the entire area, and may partition a portion of the area where a specific component is located. In this embodiment, the component seating portion 20 specifically refers to the portion where the relay 30 is mounted. A fastener hole 20' is formed through the component seating portion 20. For example, a fastening nut (not shown) is installed in the fastening hole 20', and a fastening bolt ( (not shown) may be fastened to the fastening nut. In this embodiment, two fastener holes 20' are formed in each component seating portion 20.

In this embodiment, there may be a connector base 22 on the outside of the component seating portion 20, which corresponds to one edge of the component seating portion 20 shown in FIG. 4. The connector stand 22 is for coupling with the connector portion 36 of the relay 30, which is one of the components to be described below. The connector base housing 24 may form the exterior of the connector base 22. A terminal slit 26 is formed on one side of the connector housing 24. One side of the signal bus bar 28 may be located inside the terminal slit 26. The terminal slit 26 may be cross-shaped as shown in FIGS. 4 and 5. The signal terminal 308 of the relay 30, which will be described below, can be inserted through a relatively short extending portion of the terminal slit 26.

There may be external connection parts 27 at multiple locations at the edge of the base 10. The external connection part 27 can be used for electrical connection between components inside the block and the outside of the block. One end of the power bus bar 36, which will be described below, may be located in the external connection portion 27, or the external connection terminal portion 282 and the connector 38 of the signal bus bar 28 may be located.

The signal bus bar 28 transmits signals between the inside and outside of the block. The configuration of the signal bus bar 28 is well shown in FIG. 6. A plurality of signal bus bars 28 are used. Two signal bus bars 28 are located on one connector stand 22. In this embodiment, the connector stand 22 is located at two component seating portions 20, so there may be a total of four signal bus bars 28. Figure 6 shows all four signal bus bars 28 used in this embodiment. In this embodiment, there are two connector bars 22, each of which can be used as two signal bus bars 28.

The signal bus bar 28 has a bus bar body 280, and external connection terminals 282 and component connection terminals 284 may be located at both ends of the bus bar body 280. The bus bar body portion 280 may have a predetermined width and thickness and may be shaped like a strip. The bus bar body portion 280 may be bent multiple times. The length and number of bends of the bus bar body 280 may vary depending on the distance from the location of the connector stand 22 to one edge of the base 10.

In this embodiment, the external connection terminal portion 282 has a simple pin shape. That is, it can have a rectangular cross-section in the shape of a strip with a predetermined width and thickness. The external connection terminal portion 282 may be electrically connected to a terminal of an external connector (not shown).

In this embodiment, the component connection terminal portion 284 has the shape of a fork terminal. The component connection terminal portion 284 is coupled to the signal terminal 308 of the relay 30, which will be described below. As long as it has a shape that can be electrically connected to the signal terminal 308, the component connection terminal portion 284 may have a shape other than that of a fork terminal.

In the signal bus bar 28, the bus bar body portion 280 may be installed in the base 10 as indicated by a dotted line in FIG. 4. The part of the base 10 where the bus bar body portion 280 of the signal bus bar 28 is located is called the bus bar bead 29. The bus bead 29 may protrude from the surface of the base 10. The bus bar body portion 280 of the signal bus bar 28 can be integrated into the bus bar bead 29 by insert injection. In this way, the bus bar body portion 280 is located within the bus bead 29, that is, substantially within the base 10, thereby insulating between the signal bus bars 28 and from components adjacent to the signal bus bar 28. Sufficient distance can be secured.

Next, the parts installed on the base 10 will be described. A relay 30 may be installed in the component seating portion 20 of the base 10. The relay 30 performs a switching operation. A signal for the switching operation of the relay 30 may be transmitted from the outside through the signal bus bar 28.

The relay body 300 can form the exterior and framework of the relay 30. The relay body 300 may have an overall hexahedral shape. The relay body 300 may have a connection electrode 301 connected to the power bus bar 36, which will be described below. There are two connection electrodes 301, and there may be a partition piece 301' across the connection electrodes 301. The partition piece 301' can secure an insulating distance between the connection electrodes 301.

The relay body 300 may have a mounting piece 302. The mounting piece 302 is for fixing the relay 30 to the base 10. When the relay body 300 is viewed in plan view, the mounting pieces 302 may be located at positions corresponding to corners diagonally facing each other. A mounting hole 304 may be formed in the mounting piece 302. A fastener may be fastened to the base 10 by penetrating the mounting hole 304.

There may be a connector portion 306 on one outer surface of the relay body 300. The connector housing 307 may form the exterior of the connector unit 306. The inlet of the connector housing 307 may be opened in the direction in which the relay 30 is seated on the base 10. That is, the entrance of the connector housing 307 may be formed to face the surface of the base 10. Inside the connector housing 307, a signal terminal 308 may be positioned to extend toward the inlet. The signal terminal 308 may be coupled to the component connection terminal portion 284 of the signal bus bar 28. Here, the signal terminal 308 of the connector portion 306 enters the interior of the connector housing 24 through the terminal slit 26 of the connector bar 22 and enters the component connection terminal portion of the signal bus bar 28. Can be combined with (284).

On one side of the base 10, there may be a current sensor 32, which is one of the components. The current sensor 32 can measure the current value flowing through the power bus bar 36. A connector 38 may be used to transmit the measured value of the current sensor 32 to the outside of the block. The connector 38 can be positioned fixed to one side of the external connection part 27.

As can be seen in FIG. 3, a resistor 34, which is one of the components, can be installed in the space formed on the bottom of the base 10. The resistor 34 may be installed on the upper surface of the base 10. Since the resistor 34 is installed in a space formed on the bottom of the base 10, it is possible to replace the resistor 34 without opening the cover 40, which will be described below.

A power bus bar 36 may be used to connect circuits of various components in the base 10. The size of the power bus bar 36 can be determined considering that the power provided is high voltage. The power bus bar 36 can electrically connect external power sources, loads, and components such as the relay 30. One end of the power bus bars 36 may be connected to the connection electrode 301 of the relay 30, and the other end may be located in the external connection part 27 of the base 10. The power bus bar 36 can be electrically connected by combining an external bus bar or an external ring terminal at the external connection part 27.

A plurality of connectors 38 can be installed on the base 10. The connectors 38 can perform signal connections between the block and the outside. The connector 38 may be located on the external connection portion 27. However, some of the connectors 38 are installed on one side of the base 10 rather than the external connection portion 27, and the inlet may be exposed to the outside through one side of the cover 40, which will be explained below. The external connection terminal portion 282 of the signal bus bar 28 is located in one of the connectors 38 to serve as a terminal.

Meanwhile, a vibration isolation hole 39 and a bushing 39' may be installed on the mounting piece 18 at the corner of the base 10. The vibration isolator 39 is made of a material capable of absorbing vibration, and the bushing 39' is made of a material with a predetermined strength to prevent the mounting piece 18 from being damaged by the driving force of the power tool. You can lose. For example, it may be made of metal or engineering plastic. The bushing 39' may be installed penetrating the inside of the vibration isolation hole 39. The vibration isolation hole 39 is located in a through hole formed in the mounting piece 18 and can absorb vibration between the fixing part and the automobile block.

As described above, the cover 40 may be mounted on the base 10 on which various components are installed. The cover 40 can shield the components installed on the base 10 from the outside. Of course, the cover 40 does not cover both the upper and lower sides of the base 10. In this embodiment, the portion corresponding to the upper surface of the base 10 can be shielded.

The cover 40 may include a cover plate 42 and a cover side wall 44 provided around an edge of the cover plate 42. When the cover plate 42 is viewed in plan view, it may have a shape corresponding to the plan view of the base 10. Accordingly, the cover plate 42 can shield the upper surface of the base 10.

The cover side wall 44 may surround an edge of the cover plate 42. The cover side wall 44 may be integrated with the cover plate 42. The cover side wall 44 may be in close contact with the outer surface of the base side wall 14 when the cover 40 is mounted on the base 10. For this purpose, there may be a fastening piece 46 extending from the cover side wall 44. The fastening piece 46 is capable of a predetermined elastic deformation and can be hung on the fastening jaw 14' of the base 10. A fastening hole 48 is formed in the fastening piece 46, and the fastening jaw 14' is seated in the fastening hole 48, so that the fastening piece 46 and the fastening jaw 14' are coupled. You can.

Hereinafter, the use of an automobile block in the present invention having the configuration described above will be described in detail.

In the present invention, when the base 10 is injection molded, for example, the signal bus bar 28 may be located within the mold. That is, the signal bus bar 28 is integrated with the base 10, and the component connection terminal portion 284 of the signal bus bar 28 is located within the connector housing 24 of the connector stand 22. . And, the external connection terminal portion 282 of the signal bus bar 28 may be a terminal of the connector 38 located at the external connection portion 27 of the base 10.

In this way, in a state where the signal bus bar 28 is integrated into the base 10 or the bus bar bead 29 of the base 10, the component is located within the connector housing 24 of the connector base 22. A connection terminal portion 284 is located. The component connection terminal portion 284 has a fork terminal shape and can be coupled to the signal terminal 308 inserted through the terminal slit 26 of the connector housing 24.

That is, the relay 30, which is one of the components, is seated on the component seating portion 20, and the connector portion 36 of the relay 30 can be coupled to the connector base 22 of the base 10. . To this end, as shown in FIG. 8, the relay 30 is moved to the component seating portion 20 of the base 10 in the direction of the arrow. By doing this, the mounting piece 302 can be seated at a position corresponding to the fastening nut in the fastening hole 20'. The relay 30 can be fastened to the base 10 by passing through the mounting hole 304 of the mounting piece 302 and fastening the fastening bolt to the fastening nut penetrating the fastening hole 20'.

In this process, the connector portion 306 of the relay 30 may be coupled to the connector stand 22 of the base 10. In this process, the signal terminal 308 of the relay 30 enters the interior of the connector housing 24 through the terminal slit 26 of the connector bar 22 and enters the component connection terminal portion of the signal bus bar 28. Can be combined with (284). Through this combination, the signal bus bar 28 and the relay 30 can be electrically connected. When the terminal of the external connector is electrically coupled to the external connection terminal portion 282 of the signal bus bar 28, signal transmission is possible. For example, a signal for operating the relay 30 may be transmitted through an external connector and transmitted to the relay 30 through the signal bus bar 28 to drive the relay 30.

In the process of mounting the relay 30 to the base 10, the connector portion 306 of the relay 30 must be mounted on the connector stand 22 of the base 10, so that the operator can easily check it. That is, for example, if the mounting direction of the relay 30 is rotated 180 degrees from the forward direction, the connector portion 306 cannot be coupled to the connector base 22. Of course, in this case, the mounting piece 302 of the relay 30 is in a position corresponding to the fastening nut on the base 10, but the connector portion 306 of the relay 30 is attached to the connector stand 22. Since is not coupled, the operator can recognize that the mounting direction of the relay 30 is wrong.

Also, in an embodiment of the present invention, when attempting to mount the relay 30 in a state rotated 90 degrees from its normal position, the mounting piece 302 of the relay 30 is positioned in a position that does not correspond to the fastening nut, thereby causing damage to the operator. The relay 30 cannot be fastened to the base 10. Therefore, the operator can easily recognize that the mounting direction of the relay 30 is wrong.

The relay 30, which is a component, is mounted on the component seating portion 20 of the base 10, and other components, namely, current sensor 32, resistor 34, power bus bar 36, and connector. (38), etc. are installed and the cover (40) is placed, completing the assembly of the automobile block.

In the above, even though all the components constituting the embodiment according to the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them. In addition, terms such as “include,” “comprise,” or “have” described above mean that the corresponding component may be present, unless specifically stated to the contrary, and therefore do not exclude other components. Rather, it should be interpreted as being able to include other components. All terms, including technical or scientific terms, unless otherwise defined, have the same meaning as generally understood by a person of ordinary skill in the technical field to which the present invention pertains. Commonly used terms, such as terms defined in a dictionary, should be interpreted as consistent with the contextual meaning of the related technology and, unless explicitly defined in the present invention, should not be interpreted in an idealized or overly formal sense.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these examples. The scope of protection of the present invention should be interpreted in accordance with the claims below, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.

For reference, in the present invention, the cover 40 is not necessarily required. For example, if there is no need to shield the components mounted on the base 10 from the external environment, the cover 40 may not be used.
