Description

Technical Field

[0001] The utility model belongs to the technical field of motor controllers and relates to a filter assembly. Background Art

[0002] A filter is an important electrical component used in a motor controller. In actual applications, the filter may be connected to two sets of wire harnesses at the same time. At this time, two positive copper bars are provided on the filter to be respectively used for connecting the positive connection wires in the two sets of wire harnesses. Correspondingly, two corresponding fuses are also provided. Due to space limitations, the two fuses are usually arranged side by side at the same height. However, the two sets of wire harnesses usually extend from two side-by-side socket positions. When the positive connection wires of the two sets of wire harnesses are connected to the positive copper bars, since the positive connection wires of the wire harnesses have a certain length and cannot be bent, interference occurs between the routing of the positive connection wires and the housing. When two wire harnesses need to be connected at the same time, due to the distance between the positive and negative poles of the filter and the problem of the wire harness threading method, after the positive and negative connection wires of each set of wire harnesses are connected in place, there will be a phenomenon that the wire harnesses of different polarities cross each other, which may lead to insulation skin wear and short circuit during long-term use.

[0003] To solve the above problems, a filter assembly is needed, which can effectively avoid interference between the wire harness and the housing and the phenomenon that wire harnesses of different polarities cross each other. Summary of the Utility Model

[0022] It should be noted that in the description of this specification, the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial direction", "radial direction", "circumferential direction", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In this embodiment, for the convenience of describing and understanding the present utility model, the X-direction, Y-direction and Z-direction are defined and corresponding markings are made in the drawings, which are technical means understandable to those skilled in the art.

[0023] As shown in the figure, an embodiment of the present utility model discloses a filter assembly, including a filter body 1 and a filter housing for installing the filter body 1. The filter body 1 is provided with a fuse support 5 for installing a filter fuse. The fuse support 5 is provided with a plurality of fuse installation positions 7, and the plurality of fuse installation positions 7 are arranged in a staggered manner in the Y-axis direction. In this embodiment, two fuse installation positions 7 will be taken as an example to elaborate on the present utility model. Arranged in a staggered manner in the Y-axis direction means that the two are mutually staggered in the Y-axis direction, rather than aligned. The staggered arrangement enables two different wire harnesses to have their own turning radii respectively to ensure the connection of the wire harnesses when connecting, and there will be no interference between them. Nor will there be interference or friction between the wire harness and the housing due to insufficient turning radius when arranged side by side. The wire harness of the structure of this embodiment can be directly connected or slightly bent to complete the connection.

[0024] In this embodiment, it further includes a splitter 2, which is detachably installed on the filter housing. The splitter 2 is provided with a positive fixing channel 12 for passing through and fixing the positive connection wire and a negative fixing channel 13 for passing through and fixing the negative connection wire. In the Y-axis direction and the Z-axis direction, the negative fixing channel 13 and the positive fixing channel 12 are arranged in a staggered manner. In the Y-axis direction and the Z-axis direction, the fact that the negative fixing channel 13 and the positive fixing channel 12 are arranged in a staggered manner means that no matter in the Y-axis direction or the Z-axis direction, the negative fixing channel 13 and the positive fixing channel 12 are not in the same direction as shown in the figure, they avoid each other, are staggered with each other, and are not aligned. For example, Figure 3 as shown. In this embodiment, in the Z-axis direction, the negative fixing channel 13 is located above the positive fixing channel 12. In the Y-axis direction, the negative fixing channel 13 and the positive fixing channel 12 are arranged in a staggered manner, that is, not aligned. For example, Figure 3 as shown. In this embodiment, the positive fixing channel 12 and the negative fixing channel 13 are arranged in a staggered manner in two directions, so that no matter how many positive connection wires and negative connection wires are set, they are located at different positions in space, are staggered with each other in space, and avoid each other, fundamentally avoiding the situation where different-polarity wire harnesses cross each other. In this embodiment, the filter body is also provided with a wire clip 14. The wire clip 14 in this embodiment is mainly used to restrain the negative connection wire; when there are many wire harnesses or the wire harness routing distance is far, the wire clip 14 can restrain the wire harness, improve the stability of the wire harness, and avoid the vibration of the wire harness.

[0025] In this embodiment, the filter body 1 is provided with a negative terminal platform 6. In the Z-axis direction, the negative terminal platform 6 is located above the fuse installation position 7. As shown in the figure, along the Z-axis direction, the fuse installation position 7 is located below the negative terminal platform 6. In this embodiment, the positive connection wire is finally connected to the fuse installation position 7, and the negative connection wire is connected to the negative terminal platform 6. Setting the height relationship between the final fixing positions of different-polarity wire harnesses with reference to the incoming line position (that is, the positive fixing channel 12 and the negative fixing channel 13 of the splitter 2) can further avoid the crossing and contact between different-polarity wire harnesses.

[0026] In this embodiment, in the Y-axis direction, the distance from the fuse installation position 7 close to the splitter 2 to the filter housing is greater than the distance from the fuse installation position 7 far from the splitter 2 to the filter housing. As shown in the figure, the distance from the fuse installation position 7 close to the splitter 2 to the filter housing is L 1 , and the distance from the fuse installation position 7 far from the splitter 2 to the filter housing is L 2 , L 1 is greater than L 2This is set to make the wiring smoother and avoid interference between the wire harness and other components. In this embodiment, the distances are calculated from the center position of the end on the same side of each fuse mounting position 7 to the same plane of the housing. This is a distance calculation method that can be understood by those skilled in the art and will not be elaborated here.

[0027] In this embodiment, the fuse holder 5 further includes a retaining wall 9 and a guide plate 10. The retaining wall 9 is disposed at a position between any two fuse mounting positions 7. The guide plate 10 is integrally formed at the end of the retaining wall 9, and the guide plate 10 is disposed at an angle with the retaining wall 9. The guide plate 10 is disposed outside the positive terminal 8 in the Y-axis direction of the fuse mounting position 7 close to the splitter 2. As shown in the figure, the retaining wall 9 and the guide plate 10 form a semi-surrounding for the fuse mounting position 7 close to the splitter 2, that is, the side of the fuse mounting position 7 facing the splitter 2 is open, while the side facing the adjacent fuse mounting position 7 is closed by the retaining wall 9 and the guide plate 10. Since the wire harness enters the filter housing from the side of the splitter 2, if the retaining wall 9 and the guide plate 10 are not provided, after wiring, the connector of the positive connection line corresponding to the fuse mounting position 7 far from the splitter 2 may contact the connector of the positive connection line of the adjacent fuse mounting position 7 close to the splitter 2, affecting the use of the filter. Therefore, the retaining wall 9 and the guide plate 10 are provided for isolation. At the same time, the setting of the guide plate 10 can also limit the routing angle of the positive connection line corresponding to the fuse mounting position 7 far from the splitter 2.

[0028] In this embodiment, the filter housing includes an upper housing 3 and a lower housing 4. The splitter 2 is detachably mounted on the upper housing 3. In this embodiment, a plurality of splitters 2 are provided corresponding to the number of fuse mounting positions 7. In this embodiment, each fuse mounting position 7 is provided with a positive terminal 8, and the negative terminal platform 6 is provided with a negative terminal 11. At least one negative terminal 11 is provided. In this embodiment, the number of positive terminals 8 is set to be the same as the number of negative terminals 11. As shown in the figure, in this embodiment, there are two fuse mounting positions 7, and two splitters 2 are also provided, and they are arranged side by side in the Y-axis direction. Both the positive terminals 8 and the negative terminals 11 are two.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
