Definitions
- the invention relates to a device for mounting a printed circuit board on a substrate, in particular a housing.
- a device for mounting a printed circuit board on a chassis wherein the device has a head with resilient side edges.
- the head goes in the region of the side flanks over a neck to the fuselage, wherein between the underside of the resilient side edges and the trunk in the region of the neck, a circuit board is a clip-in receivable.
- the chassis receives the device clipped.
- Inverters have a housing with one or more covers, wherein the housing is in particular made of a conductive material, in particular aluminum die-cast.
- the circuit boards have various electrical and electronic components are attached to the housing. For attachment is particularly provided that the circuit boards are bolted to the housing.
- Printed circuit boards also have a large number of printed conductors. When screwing the printed circuit board on the housing is to ensure that the tracks of the circuit board have a sufficient distance from the screw. It follows immediately that the
- printed circuit boards must already have a certain size in order to ensure that air gaps and creepage distances are maintained between the conductor tracks of the printed circuit board and the screw connections in the housing.
- a device for fixing a circuit board on a housing or a base, a device has a spike-like foot for receiving through the pad, wherein on the foot a retaining clip for fixing the circuit board is provided, wherein the foot below of the retaining clips, the document directed to a circumferential insulating body is arranged.
- Screw connections between PCB and housing can be reduced.
- the retaining clip is tapered upwards, this
- the subject of claim 1 is a so-called circulating
- Insulating body is attached to the foot below the retaining clip. Because this air and creepage distances between the conductors and the housing made of electrically conductive material can be adhered to, without giving away space on the circuit board. This is especially true when the pad has a dome-like elevation with an opening for receiving the spike-like foot, with such an advantageous embodiment of the insulating body is pot-shaped and the dome-like elevation laterally overturned, so that a secure insulation is given. This not only with the result that the conductor tracks directly on the device for mounting the circuit board on the
- Housing can run along, but it is also thereby achieved a reduction in the height, since the distance between the circuit board and the housing or dome-like elevation can be reduced by the rotating insulating body, especially in pot-like training.
- means for compensating tolerances in particular in the form of an elastically yielding plate, are provided between the retaining clip and the insulating body.
- this plate in conjunction with the retaining clip ensures that the circuit board is held securely. This is especially true when the edge of the plate is angled in the direction of the retaining clip. As a result, a certain spring effect is generated, which ensures, as already stated, secure hold of the circuit board on the housing.
- the retaining clip which is formed conically upwards, ie in the direction of the circuit board, as already described above, at least one in the direction of the longitudinal axis of the device obliquely tapered arm, wherein the at least one arm is designed to spring in laterally, wherein the at least one arm has a latching nose for fixing the printed circuit board.
- the housing or the base has a dome-like elevation, which serves to accommodate the thorn-like foot.
- the spike-like foot in the pot-like insulating body shows a portion of an outer circumferential surface having a diameter which approximately corresponds to the inner diameter of the dome-like elevation, wherein the section is followed by a tapered approach .
- Inventive device is tightly pressed into the dome-like elevation.
- the drawing shows schematically the arrangement of the device according to the invention on the rear wall of a housing, in particular on the rear wall of an inverter housing, wherein the designated housing 1 made of die-cast aluminum has a dome-like elevation 2, which serves to receive the device designated 10.
- the device designated 10 has the spike-like foot 11 which is seated in the bore 3 of the dome-like elevation.
- the thorn-like foot has a portion 11 a, with which the foot is tight at the
- Insulating body which is pot-shaped, as can be seen directly from the drawing.
- the cup-like design of the insulating body is in this case such that the dome is slipped over by the insulating body.
- Screws for mounting a circuit board on the dome-like elevation as is the case in the prior art.
- the elastically yielding plate 16 Above the cup-shaped insulating body is the elastically yielding plate 16, the edges of which are bent in the direction of the retaining clip designated 18.
- the retaining clip 18 has two in the direction of the longitudinal axis
- pivotable arms 19, and which are also resiliently connected to the retaining clip 18, and each with a detent 19a are provided so that after passing through the retaining clip through the bore 21 in the circuit board 20, the circuit board is fixed by the device.
- dome 30 On the rear wall of the housing, another dome 30 is provided, which serves for a screw connection to the circuit board, without this being shown in more detail. From this it is clear that the circuit board is secured by screws as well as by the device according to the invention to the housing.
