Definitions
- the invention relates to a vacuum pump with a vacuum-tight housing, which contains a motor and a pump rotor, and with a current feedthrough, which has a printed circuit board.
- Vacuum pumps in the form of turbomolecular pumps contain a rotor which rotates at a very high speed and is therefore able to generate a high vacuum. Often the rotor and the motor driving it are stored in magnetic bearings. In the housing there is a vacuum, usually below 10 mbar. The power supply lines for the motor and the magnetic bearings are provided vacuum-tight on the housing.
- EP 1 757 825 A1 describes a vacuum pump in which the power supply into the housing has a printed circuit board. The inside of the printed circuit board lies with the interposition of a seal on the housing and the outside is, with the interposition of another seal to an outer vacuum cover, which closes the housing vacuum-tight. The printed conductors of the printed circuit board pass through the gap between the two seals. The circuit board has outside of the housing on a projection on which a connector is provided. Another connector is in contact with the printed conductors inside the housing.
- the invention has for its object to provide a vacuum pump, wherein the current feedthrough has no protruding over the housing circuit board parts, so that damage to the circuit board and exposed plug devices are avoided.
- the vacuum pump according to the invention is defined by claim 1. It has a printed circuit board with a first and a second seal, wherein the first and the second seal are laterally offset from each other, so that in a portion of the circuit board outside the atmospheric pressure and inside the generated vacuum acts.
- the portion which is subjected to a pressure differential and does not protrude laterally beyond the wall of the housing can serve to connect electrical conductors to the circuit board.
- the circuit board In the wall region of the circuit board in which the pressure difference is effective, the circuit board itself forms the wall of the pump. Bending is prevented in this part because the circuit board can be supported against the front end of the wall of the housing.
- the vacuum cap, which forms the vacuum seal of the housing is arranged according to a preferred embodiment of the invention in a protective cover and movable relative thereto.
- the possibility of movement perpendicular to the cover plane makes it possible to press the seal.
- the vacuum lid is held by the pressure difference acting on it and only loosely positioned by the protective cover.
- the protective cover is used to prevent damage to the vacuum lid and the circuit board. In addition, it can serve as a carrier for a plug-in device for connecting the external electrical conductor leading to the printed circuit board.
- the protective cover contains a positioning device for positioning the vacuum cap, but allows reactions of the vacuum cap on the prevailing pressure difference. Alternatively, it is also possible to form the vacuum cover in one piece with the protective cover.
- Fig. 1 is a partial longitudinal section through the housing of a vacuum pump with
- Fig. 2 shows a second embodiment of the current feedthrough, wherein the
- Printed circuit board is additionally equipped with electrical components.
- FIG. 1 shows the housing 10 of a turbomolecular pump.
- the housing 10 includes a motor and a pump rotor. It has a pump inlet 11 at one end and a pump outlet 12 at its periphery. At the pump inlet 11, the vacuum is generated.
- the pump outlet 12 may lead to the atmosphere or to a backing pump.
- An annular wall 13 of the housing has a flat end face 14 at the rear end.
- the end face 14 includes in a groove an annular first seal 15 in the form of an O-ring.
- a circuit board 16 is set, which consists of an insulating body, which is provided on one side or both sides with (not shown) conductor tracks.
- printed circuits are also referred to as "printed circuits.”
- the printed circuit board 16 bears sealingly against the seal 15. It contains a pressure equalization opening 17 in the middle region, which is surrounded by the end face 14.
- the printed circuit board 16 has an interior space Pump facing the inside 18 and an inner side facing away from the outside 19. The inside 18 abuts the first seal 15.
- a vacuum cap 20 is placed against the outside 19 of the circuit board.
- the vacuum cap contains an annular groove with a second seal 21.
- This seal is also an O-ring ring seal.
- the second seal 21 has a smaller opening diameter than the first seal 15.
- an annular portion 22 which is exposed to the prevailing pressure difference, because on its outside the atmospheric pressure acts and on its inside the vacuum.
- the vacuum cover 20 is thus pressed by the atmospheric pressure in the direction of the wall 13.
- the housing 10 is closed at its front end by a protective cover 23, which has no sealing function.
- the protective cover 23 includes a cavity 24 for receiving the vacuum cover 20 and a positioning device 25 in the form of a stepped shoulder for positioning the vacuum cover 20. It protects the vacuum cover and the circuit board and the parts connected thereto.
- electrical lines 26 extend into the inner housing. These lines may be power supply lines or control or signal lines. They are soldered or plugged to the tracks of the circuit board.
- External electrical conductors 27 are soldered or plugged to the outside 19 of the circuit board 16.
- the conductors 27 lead through the interior 24 to a plug-in device 28 in the form of a multiple electrical plug.
- the plug-in device 28 is used to connect an external cable. It is arranged on a side surface of the protective cover 23, but could also be arranged on the rear surface.
- the printed circuit board 16 does not protrude laterally beyond the side wall 13.
- the portion 22 between the seals 15 and 21 serves as a connection region for the electrical conductors 27th
- the embodiment of Figure 2 differs from that of Figure 1 only in that the circuit board 16 is additionally equipped with electrical components 30, such as resistors, capacitors, processors or storage.
- the components 30 can be both active and passive components.
- the vacuum lid 20 includes a recess which is surrounded by the seal 21 bearing edge. This recess 31 is used in Figure 2 for receiving the attached to the outside of the printed circuit board 19 components 30th
