Description

Busbar fastening apparatus for battery distribution unit

The present invention relates to a battery distribution unit, and more particularly to a bus bar height device of the battery distribution unit in minimizing the flow of the coupling portion for coupling with the counterpart in the installation of the bus bar in the battery distribution unit.

In the vehicle using the engine, the voltage of the power supply mainly used was a low voltage of about 12 volts. Recently, however, a relatively high voltage is required for a hybrid or an electric vehicle using an electric motor.

Therefore, the parts used in the vehicle have been used only for low voltage, and high voltage is also required. However, if the box is made separately for the high voltage component and the low voltage component, for example, the number of parts of the vehicle as a whole increases.

In order to solve this problem, for example, it has been proposed to combine high voltage and low voltage components in one box. However, in using the high voltage component and the low voltage component together, the parts corresponding to the high voltage component need to be installed at a more accurate position. For example, for busbars used for high voltages, the flow of the joint must be within a specified value. However, the existing product has a problem that does not satisfy this value.

Accordingly, an object of the present invention is to satisfy the necessity as described above, and more particularly, to firmly install a bus bar for a high voltage product used in a vehicle.

According to a feature of the present invention for achieving the object as described above, the present invention is provided with an insulating plate to partition the space between the first plate and the second plate body, the first plate and the insulation plate, the insulation plate and the first plate A bus bar fixing device for a battery distribution unit in which a first bus bar and a second bus bar are disposed between two board bodies, wherein the inner partition wall penetrates the insulating plate from the second board body toward the first board body. A support rib protruding toward the first plate body and protruding toward the support rib from an inner surface of an outer partition formed on the insulating plate to correspond to a thickness of the coupling portion of the second bus bar between the support rib and the support rib; A support protrusion having a gap and a body portion of a second bus bar which is extended below the outer partition wall of the insulating plate and seated on the second plate body on the second plate body; It consists of a pressing rib.

The support protrusion presses the coupling portion of the second bus bar in a portion adjacent to the body portion and closely adheres to the support rib, and the push rib presses the body portion of the second bus bar in a portion adjacent to the coupling portion with a second plate body. In close contact.

The height of the support rib is about 40% of the height of the coupling portion of the second bus bar and supports the female terminal installed in the inner partition.

An insertion guide inclined surface is formed at an end of the support protrusion to face the coupling part side of the second bus bar at an angle.

The tip of the support protrusion is at a position corresponding to the middle height of the support rib.

An inlet partition wall is formed on a lower surface of the first plate body to surround an upper portion of the inner partition wall, and a portion corresponding to the opening of the inlet partition wall is relatively thicker than other portions of the inlet partition wall to shield the opening formed in the inner partition wall. Thick rear wall.

In the bus bar fixing device of the battery distribution unit according to the present invention, the following effects can be obtained.

In the present invention, the coupling portion of the busbar may be more firmly fixed by the support ribs, the support protrusions, and the pressing ribs, which are structures formed on the second plate body and the insulating plate. There is no effect that the safety of the product becomes higher.

In addition, the present invention prevents the rear wall portion of the inlet bulkhead from flowing in the inner bulkhead of the female terminal coupled to the coupling part of the bus bar, thereby facilitating the installation of the female terminal while preventing the flow of the female terminal. The effect which can be reliably prevented can be obtained.

At this time, the body portion 52 of the second bus bar 50 passes through the opening 26 ′ of the inner partition 26.

When the second bus bars 50 are all disposed on the second plate body 20, the insulating plate 30 is seated on the surface of the second plate body 20. At this time, the coupling part 54 of the second bus bar 50 is inserted into the inner space of the outer partition 32 of the insulating plate 30.

In this process, the support protrusion 34 protruding from the inner surface of the outer partition 32 has an insertion guide inclined surface 34 ′ at its tip to guide the tip of the engaging portion 54 of the second bus bar 50. To minimize interference with each other.

When the insulating plate 30 is seated on the second plate 20, the outer partition 32 of the insulating plate 30 surrounds the lower portion of the inner partition 26 of the second plate 20. . In this case, the lower portion of the opening 26 ′ formed in the inner partition 26 is shielded by the outer partition 32.

And, as can be seen in Figure 2, the pressing rib 36 formed in the insulating plate 30 is pressed to support the body portion 52 of the second bus bar 50 on the surface of the second plate body 20 Done. In addition, the support protrusion 34 of the insulating plate 30 is provided with a tip at a position corresponding to the middle height of the partition rib 27 of the second plate body 20 in cooperation with the partition rib 27 The coupling part 54 of the second bus bar 50 is supported. The coupling portion 54 of the second bus bar 50 is precisely installed at the same time as the partition rib 27 and the support protrusion 34, and the flow is minimized. In this way, the insulating plate 30 is coupled to the second plate body 20, as shown in FIG. 3.

Next, the first bus bar 40 is disposed on the insulating plate 30, and the female terminal 60 is coupled to the coupling part 54 of the second bus bar 50. The body part 42 of the first bus bar 40 is disposed on the surface of the insulating plate 30, and the coupling part 44 extends toward the first plate body 10. The female terminal 60 is supported on the upper end of the support rib 28 to prevent the flow and falling. In particular, the rear wall portion 18 ′ supports the female terminal 60 so as not to flow in the inner partition 26. If the female terminal 60 does not flow, the coupling portion 54 of the second bus bar 50 does not flow.

In this state, the first plate body 10 is coupled to the second plate body 20. Coupling between the first plate body 10 and the second plate body 20 is made by the engaging jaw 22 is coupled to the hook hole 12 'of the hook piece 12. In addition, the inlet partition wall 18 of the first plate body 10 surrounds an upper portion of the inner partition wall 26 of the second plate body 20. That is, as shown in FIG. 2, the inlet partition 18 is disposed around the inner partition 26, and a relatively thick portion of the inlet partition 18 is an opening of the inner partition 26. 26 ') to support the female terminal 60.

And, the cut portion 19 of the inlet partition 18 is sandwiched between the outer partition 32 and the adjacent partition 33 of the insulating plate 30, the insulating plate 30 and the first plate body 10 ) Make the bond between the two stronger.

In this way, the assembly is completed, the component is mounted to the component mounting portion 14, the terminal of the component is inserted into the inner space of the inner partition 26 through the terminal through hole 16 and the female terminal 60 Is coupled to.

In the present invention, the unit is used to be mounted to the panel or chassis of the vehicle by using the mounting portion 24, the unit is used to connect the wires coming from the battery side and combine the external connector.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and those skilled in the art will be able to make various changes and modifications within the scope of the claims It is self-evident.
