Technical Field

The present invention relates to an electronic device and a system including the electronic device and two pairs of bus bars.

Background

Electronic devices are typically manufactured with integrated bus bars (e.g., copper bus bars). However, existing electronic devices have low flexibility in adapting to changes in the geometry of the interface to which the electronic device is to be connected.

Disclosure of Invention

It is an object of the present application to provide an improved electronic device, e.g. an electronic device with an improved degree of flexibility.

This object is solved by the subject matter of claim 1.

An electronic device is provided that includes a housing and at least one electronic component disposed within the housing. The housing is adapted for feed-through of at least one bus bar. The housing is compatible with differently shaped bus bars.

The bus bar itself is not part of the electronic device. Instead, the electronic device is configured to receive the bus bar. The bus bar may be inserted into the electronic device so as to protrude from the electronic device. Because the electronic device is compatible with bus bars of different shapes, the electronic device has a great degree of flexibility in adapting to changes in the geometry of the interface. The electronic device may be a standardized electronic device, wherein the electronic device may be combined with various interfaces by selecting appropriate bus bars.

The housing may be adapted such that the housing does not impose a limitation on the shape of the terminal of the at least one bus bar. The terminal may be an end portion of the bus bar configured to be connected to a power source or an interface. The bus bar may be configured to apply a voltage from a power source to the electronic components within the housing as the bus bar is fed through the housing.

The housing may comprise a tube adapted for feed-through of the at least one bus bar, wherein the tube extends from a first end of the housing to a second end of the housing. When the bus bar is disposed in the tube, the bus bar may protrude from both the first end and the second end of the housing. The portions of the bus bars protruding from both ends of the case may be terminals of the bus bars.

The housing may include a fixing member configured to fix the at least one bus bar after the at least one bus bar is inserted into the housing. The fixing member may mechanically fix the bus bar. For example, the fixation element may comprise a screw. Alternatively, the fixing element may comprise a clip.

At least one of a capacitor and an inductor may be disposed as the electronic component in the case. The capacitor may be a Y capacitor or an X capacitor. The inductor may be a magnetic core arranged so as to surround the bus bar as it is fed through the housing. The inductor may be a magnetic core surrounding the tube.

The electronic device may not have an integrated bus bar. The integrated bus bars may limit the flexibility of connecting the electronic device to different interface geometries.

The electronic device may be an EMC filter.

The electronic device may include a connection point within the housing. At least one electronic component may be electrically connected to the connection point. The electronic device may be configured such that the bus bar fed through the housing is electrically connected to the connection point. The connection point may be a metallization at the inner wall of the tube. By means of these connection points, voltage and current can be applied from the bus bar to the electronic component.

Another aspect relates to a system that includes the electronic device described above, a first pair of bus bars, and a second pair of bus bars. The first pair of bus bars is different from the second pair of bus bars in shape. In particular, the first and second pairs of bus bars may differ in the shape of their terminals. The housing of the electronic component is compatible with both the first and second pairs of bus bars. The housing of the electronic component is adapted for feed-through of a first pair of bus bars and for feed-through of a second pair of bus bars.

Each of the first pair of bus bars may include a metallic strip (metallic strip) and a terminal arranged at a first angle to the metallic strip. Each of the second pair of bus bars may include a metal strip and a terminal disposed at a second angle to the metal strip. The second angle may be different from the first angle.

For different applications and for connections to different customer interfaces, the electronic components may be connected to the first pair of bus bars or to the second pair of bus bars depending on the geometry of the customer interface. The same electronic component can be combined with different interfaces by selecting the appropriate bus bar. No modification of the electronic components is required.

Detailed Description

Fig. 1 shows an electronic device 1 in a perspective view. Fig. 2 shows the electronic device 1 by a schematic diagram.

The electronic device 1 is an EMC filter. The electronic device 1 includes a housing 2 and electronic components Cy, Cx, L arranged within the housing 2. In particular, the capacitors Cy, Cx and the inductor L are arranged within the housing. The capacitors are Y capacitors and X capacitors. The electronic device may comprise a printed circuit board arranged within the housing 2, wherein some of the electronic components Cy, Cx are arranged on the printed circuit board.

The housing 2 is suitable for feed-through of pairs of bus bars. In particular, the housing comprises a first tube 3 and a second tube 4, both extending from a first end 2a of the housing 2 to a second end 2b of the housing 2 opposite the first end 2 a. Each bus bar may be inserted into one of the tubes 3, 4. The bus bars may be inserted into the tubes 3, 4 such that one end of the bus bar protrudes from the first end 2a of the housing 2 and the other end of the bus bar protrudes from the second end 2b of the housing 2.

The housing 2 comprises a connection point 5. Each of the connection points 5 is electrically connected to one of the electronic components Cx, Cy in the housing 2. In particular, each of the connection points 5 is connected to one of the capacitors Cx, Cy. The housing 2 is adapted and arranged such that the bus bars are electrically connected to some of the connection points 5 when the bus bars are inserted into the housing 2.

In particular, the housing 2 comprises a first set of connection points 5 and a second set of connection points 5. The connection points 5 in the first set are arranged at the inner wall of the first tube 3. The connection points 5 in the second set are arranged at the inner wall of the second tube 4.

The housing 2 is adapted and arranged to: so that when the first bus bar is inserted into the housing 2, the first bus bar is electrically connected to the connection points 5 in the first group; and such that the second bus bar is electrically connected to the connection points 5 in the second group when the second bus bar is inserted into the housing 2. A voltage can be applied to the electronic components Cx, Cy inside the case 2 via the bus bar and the connection point 5.

An insulating material may also be disposed within the housing 2 and optionally be a resin.

The housing 2 has no limitation on the shape of the terminal of the bus bar. Bus bars whose terminals are different in shape can be fixed to the housing 2. The housing 2 is compatible with various different shaped bus bars.

Fig. 3 illustrates the interconnection of the electronics shown in fig. 2 with the motor 17 and the inverter 18.

The inverter 18 includes a first bus bar 6a and a second bus bar 6 b. The first bus bar 6a and the second bus bar 6b are fed through the electronic device 1. Each of the bus bars 6a, 6b is electrically connected to four connection points 5.

The contact between the bus bars 6a, 6b and the connection point 5 is closed via a spring-loaded connection 7, in particular via a spring-loaded nail fastener. The spring-loaded connector 7 can moderate the forces acting on the bus bars 6a, 6b and ensure that these forces are not transmitted to the electronic components Cx, Cy. Furthermore, the spring-loaded connector 7 can moderate the weight of the bus bars 6a, 6b and thus mechanically relieve the load on the electronic components Cx, Cy.

Fig. 4 shows a perspective view of four pairs of bus bars 6a, 6 b. Each of the bus bars 6a, 6b is configured to be fed through the housing 2 of the electronic device 1.

Each of the bus bars 6a, 6b includes a main body and a terminal 9. The body consists of a metal strip 8 shaped as a straight line. The terminal 9 is arranged at a first end of the main body configured to protrude from the first end 2a of the housing 2 when the bus bars 6a, 6b are fed through the housing 2.

Each of the four pairs of bus bars 6a, 6b has the same main body formed of the metal strip 8, and each of the four pairs of bus bars 6a, 6b is different from the other pairs in the shape of the terminals 9. For each of the four pairs of busbars 6a, 6b, the shape of the respective terminal 9 is different from the shape of the straight metal strip 8 forming the body.

In the first pair 10 of bus bars 6a, 6b, the terminal 9 includes a first section 10a and a second section 10 b. The first section 10a of the terminal 9 is adjacent to the metal strip 8 of the body. The second section 10b of the terminal 9 is adjacent to the first section 10 a. Thus, the first section 10a is arranged between the second section 10b and the metal strip 8.

The first section 10a is perpendicular to the metal strip 8. The second section 10b is parallel to the metal strip 8. The first section 10a provides an offset of the second section 10b relative to the metal strip 8.

In the second pair 11 of busbars 6a, 6b, the terminals 9 form an extension of the metal strip 8. The terminal 9 of each of the two busbars 6a, 6b comprises a tab 11a projecting sideways from the elongated metal strip.

In the third pair 12 of busbars 6a, 6b, the terminals 9 are perpendicular to the metal strips 8. The first busbar 6a of the third pair is inverted with respect to the second busbar 6b of the third pair. The terminals 9 of the first bus bar 6a protrude in an upward direction perpendicular to the metal strips 8, and the terminals 9 of the second bus bar 6b protrude in a downward direction perpendicular to the metal strips 8.

In the fourth pair 13 of busbars 6a, 6b, the terminal 9 comprises a first section 13a and a second section 13b similar to the first pair 10 of busbars. The first section 13a of the terminal 9 is adjacent to the metal strip 8 of the body. The second section 13b of the terminal 9 is adjacent to the first section 13 a. Thus, the first section 13a is arranged between the second section 13b and the metal strip 8.

The first section 13a forms an obtuse angle with respect to the metal strip 8. The obtuse angle may be, for example, 10 °. The second section 13b is parallel to the metal strip 8. The first section 13a provides an offset of the second section 13b relative to the metal strip 8. The offset in the fourth pair 13 is smaller than the offset in the first pair 10.

The four pairs of 10 to 13 bus bars 6a, 6b shown in fig. 4 are an example of a plurality of pairs of bus bars that can be combined with the electronic device 1. Each of the bus bars 6a, 6b shown in fig. 4 may be inserted into the housing 2. Each of these pairs of busbars 6a, 6b provides a different terminal 9 for connection to an interface designed for the customer.

Fig. 5 shows an arrangement in which the busbars 6a, 6b shown in fig. 4 are fed through the electronic device shown in fig. 1. Different bus bars 6a, 6b may be fed through the electronic device 1. The electronic device 1 is compatible with different bus bars 6a, 6 b. In particular, the arrangement shown in fig. 5 differs in terms of the position of the terminals 9 of the bus bars 6a, 6 b.

The electronic device 1 can be standardized and combined with differently shaped bus bars 6a, 6b to accommodate connection to different customer designed interfaces. The flexible bus bar configuration can be matched to customer requirements for its interface. The client interface can be adapted without any modification of the electronic device 1.
