Definitions
- the invention relates to a removal device for electrical Electricity according to the preamble of claim 1.
- an electrical quantity in particular an electrical quantity Electricity to tap as lossless and / or trouble-free as possible or transfer. Furthermore, with their electrical quality also good mechanical handling and stability to be guaranteed.
- Switching, transmission or acceptance modules - which are below are simply called modules and so-called Should include diode modules or uncontrolled modules - the known tapping devices for high currents a flat and flat conductor substrate, in particular a DCB / AlN substrate, soldered in such a way that they project substantially perpendicularly from the conductor substrate. Then a housing carrying the switching elements is placed on the Arrangement of conductor substrate with soldered current tapping tabs put on. To do this, the appropriate housing must be suitable Places have slots through which the known Tapping devices for electrical current threaded through become. Because of their band or plate-like Structure can be damaged when the housing is put on the arrangement of the belt or sheet-like removal devices for electric current of the conventional form e.g. by twisting or canceling.
- the invention has for its object to provide a tapping device for electrical current, which can be used, in particular for line semiconductor, switching, transmission and / or tapping modules, for the transmission and switching of high current or load current and which thereby have increased mechanical stability having.
- the transmission area has a first and a second end region, which with the first or with the second contact area are connected, it is provided according to the invention that at least the transmission area is designed to use the second contact area has a substantially hollow profile Form arrangement.
- the first and second contact areas can each as primary contact areas for current consumption and / or in each case as secondary contact areas for delivering electrical Electricity or an electrical quantity serve.
- Tapping devices for electrical current are in the transmission range at least a first leader and a second Head provided. It is particularly advantageous that the at least two conductors of the transmission area essentially have the same geometric properties.
- the plate or areal current draw only one at a time has a single power route, a plurality of power routes intended. On the one hand, this reduces the the current cross-section in each case acting current density, whereby Ohmic losses in the overall route can be reduced.
- the head of the transmission area essentially have the same geometric properties.
- the different heads of the Transmission range also the respective geometric properties adapted to the module or the respective application e.g. with regard to a special one to be used Housing or the like.
- the head of the transmission area essentially plate-shaped and in particular are planar. Also result with these properties particularly favorable manufacturing conditions, whereby but again special circumstances are taken into account what can then be a deviation from planarity or training in plate form may be necessary.
- a particularly simple arrangement results when the ladder of the transmission area is essentially rectangular are, each with an upper edge area and / or a lower edge area can be provided for the conductors. It is also preferable in terms of production technology that the Head of the transmission area over their course one have essentially constant strength. This also leads to the fact that in the course of the ladder regarding the Conductor cross section do not result in any ohmic weak points.
- the second contact area than essentially plate-shaped, in particular planar, head is formed.
- Tapping device for electrical current results that the upper edge areas of the ladder of the Transmission area each with one of the side edge areas of the conductor of the second contact area are that the conductors of the transmission area each have side walls and the head of the second contact area one Cover plate or a top wall of a jointly trained Form hollow profile. It is particularly advantageous if the head of the transmission area in a given Direction are arranged and the conductor of the second contact area in a direction substantially perpendicular to this direction Direction is arranged so that through the transmission area and the second contact area essentially a U-profile is formed.
- This arrangement thus ensures that an electrical Electricity e.g. is picked up by the first contact area and then in parallel over the side walls of a U-profile, the straight from the conductors of the transmission area in plate form are formed parallel to each other, to the secondary Contact area, which is vertical through the corresponding conductor is formed to the side walls of the U-profile, transferred becomes.
- the conductors of the transmission area can also be arranged in this way that there is a different profile shape overall, e.g. the profile of an O, or such that the space in the O or U profile by other, possibly parallel trending, head of the transmission area and / or is filled up.
- the first contact area Has conductor elements through which the removal device with a conductor, in particular a circuit board, on a substrate, in particular a DCB / ALN substrate, or the like, is contactable.
- the conductor elements of the first Contact area for mechanical contact are formed by soldering, welding or the like.
- the conductor elements designed to be resilient or elastically deformable, e.g. thermal expansion or mechanical stress during assembly, e.g. when putting on a housing or when Contact field. This can advantageously be done by the provision of expansion arches, folds or the like will be realized.
- the head of the transmission area at least in each case a conductor element of the first contact area is formed is. This only results from the similarity the head of the transmission area and the design symmetry of the conductor of the second contact region the removal device according to the invention for electrical Current and thus a symmetrical current flow.
- the symmetry of the electrical device including the symmetry of the conductor elements of the first contact area may have manufacturing advantages because especially when using a symmetrical removal device for electrical current in the above Switching or transmission modules, then also correspondingly symmetrical current-carrying or current-discharging basic substrates, e.g. in the form of corresponding base plates with a DCB / AlN substrate can be executed. So then it's just a single type of tapping equipment or power take-off to manufacture and keep in stock.
- the removal device according to the invention for electric current especially the Entire of first contact area, transmission area and second contact area, in one piece and in particular from one be made of uniform material. Then namely can a corresponding number of in a prefabrication process Tapping devices for electric current punched out, pre-bent and pre-assembled, so that this way and also results in a process that can be fed to automation.
- the acceptance device in particular the first Contact area and / or the second contact area, completely or are selectively surface-coated, in particular with silver, nickel, tin, tin-lead or the like.
