Definitions
- the invention relates to a method for producing a low-inductance busbar having first terminals, a plurality of first busbar strips arranged in a first busbar plane, a plurality of second busbar strips arranged in a second busbar plane, a plurality of capacitors electrically connected to the busbar strips and having second connections.
- Such a busbar is used in electrical power distribution. It consists of a plurality of strips of copper or aluminum, which conduct the power from an input to an output.
- busbars serve to connect capacitors to an electrical switch.
- the busbar strips are arranged so that the current flows through them in opposite directions, so that cancel the induced by the current flow inductions.
- busbar In such a busbar is to ensure on the one hand that no moisture can penetrate into this, which could lead to a short circuit. It must also be ensured by suitable measures that the busbars are isolated from each other and from the environment.
- DE-12 06 043 A, DE 1934238 A and DE 3148382 AI show the production of conductor gratings, which are isolated from each other by films on which various components, eg. As capacitors, are attached and then shed.
- the stated object is achieved by providing a shell with a bottom and an upstanding on this to form a frame Edge of an electrically insulating material, producing a busbar element by arranging the first busbar strips forming the first busbar plane, applying a foil provided with the openings to the first busbar strip to the first busbar strips, arranging the second busbar strip forming the second busbar layer on the foil, bending the portions of the bus bars forming the terminals, applying and electrically contacting the capacitors through the apertures in the foil to the first and second bus bars, inserting the bus bar into the shell and encapsulating the shell with a potting compound (resin) the bottom - of the capacitors to below the edges of a frame forming edge, leaving the connections.
- a potting compound resin
- the invention therefore proposes to provide a busbar by providing a shell which is provided with a bottom and an edge of an electrically insulating material circumferentially rising thereon to form a frame.
- a sliding element is produced by arranging the first busbar strips forming the first busbar plane, applying a foil provided with openings allowing access to the first busbar strips to the first busbar strips, arranging the second busbar strips forming the second busbar layer on the foil above, the portions of the bus bars forming the terminals bend, applying and electrically contacting the capacitors through openings in the foil to the first and second bus bars.
- the rail element thus formed is then inserted into the shell. Subsequently, the shell is poured with a synthetic resin, including the bottom of the capacitors to below the edges of a frame-forming edge, leaving the upwardly bent terminals remain free.
- the invention will be explained below with reference to a drawing.
- the single figure shows a sectional view through the bus bar thus produced.
- the busbar consists of a shell 20 with a bottom 22 and a circumferentially on the bottom 22 upstanding edge 24 to form a frame, wherein at least the bottom consists of an electrically insulating material.
- a busbar member is formed, which is formed by arranging the first busbar layer 12 forming the first busbars 12 provided with the input terminals 10 of the busbar, the input terminals 10 being upwardly bent portions of the busbars 12. Then, a film 1 is placed on the first rail level forming busbar strips 12, wherein the film 28 is provided with openings that allow access to the first busbar strips 12. Then, a second busbar plane forming second busbar strips 14 are arranged on the film 28, wherein the busbar strips 14 are provided with terminals 18 which are formed by bending up a portion of the second busbar strips 14, then capacitors 16 on the first and on the second Rail strip 14 possibly applied through the openings 16 in the film, 28 through, mechanically connected thereto and electrically contacted.
- the rail element thus formed is then inserted into the shell 20. Then, the shell 20 is poured with a synthetic resin 30 while enclosing the bottom of the capacitors 16 to below the edges of the rim forming a frame 24, leaving the terminals 10, 18th
- the synthetic resin 30 is thereby introduced into the shell to a height at which the capacitors are enveloped by the synthetic resin to give sufficient stability.
- the so-formed busbar is protected against the ingress of moisture, it is insulated on all sides and allows a largely automated production, even in larger quantities.
