COMPUTER SYSTEM AND HOLDER HOLDER FOR AN INSERT CARD The invention relates to a computer system which has a

Has support plate and a perpendicular to the support plate arranged wall. Furthermore, the invention relates to a

Retainer for use in such a computer system. Computer systems with a carrier sheet on which a

Printed circuit board is arranged with at least one connector, are widely known from the prior art. With the connector, a plug-in card can be contacted, which can be fixed by means of a slot defined at her on another wall. At a the

Slotwinkel opposite side of the plug-in card, this is typically performed in a rail or fixture. An object on which the invention is based is to describe an alternative mounting possibility of a plug-in card in a computer system.

According to a first aspect, a computer system is disclosed which has a carrier plate and a wall arranged perpendicular to the carrier plate. The computer system further includes a circuit board with a connector. The

PCB is set parallel to the carrier plate at this. Next is a plug-in card with a

Slot angle provided, which is set in the region of a first side of the plug-in card at this. The plug-in card is electrically coupled to the connector, in particular inserted in this, and by means of the slot angle at the Wall set. Furthermore, a headband

provided, which with a first end portion on the

Carrier plate is fixed and with a second end of the plug-in card in the area of one of the first page

encompasses the opposite second side. By means of the

Holding clip the plug-in card is mechanically secured to the support plate in the region of the second side.

The carrier plate, the circuit board and the plug-in cards are located within a housing of the computer system. The wall arranged perpendicular to the carrier plate is, for example, a housing side of the housing or a further carrier plate within the housing. The computer system according to the first aspect makes it possible to mechanically fix a plug-in card in the region of both ends. This is necessary to forces that

For example, during transport or drop tests can occur, catch and avert damage from the card. In particular, the circuit board on the side facing away from the slot angle on the headband on the

Set carrier plate and thus securely held in the connector. As a result, the plug-in card can not easily disconnect from the connector and is in this

Area of the second side is not arranged freely floating inside the computer system. In addition, proves to be

advantageous that in the area of the second side of

Plug-in card no corresponding holding devices such as the rails mentioned above must be provided. This can be useful, for example, if due to a very compact design of computer systems space is to be saved. For fixing the retaining clip on the support plate, for example, a fastening opening is provided. In this, the first end area is suspended, for example. The

Mounting hole can be easily stamped or punched in the carrier plate.

According to another embodiment, the second surrounds

End portion of the retaining clip a narrow side of the

Plug-in card, which faces away from the carrier sheet,

at least partially positively, so that the plug-in card is subjected to a mechanical stress. The narrow side is preferably a longitudinal side of the plug-in card which connects the first side and the second side of the plug-in card. The application of mechanical tension ensures that the plug-in card does not float loosely in the region of its second side, but is held particularly well in its position. The mechanical stress acts in the direction of the carrier plate. According to a further embodiment, the first end region is anchored or T-shaped and formed in one

corresponding attachment opening of the carrier sheet

anchored. This is a very simple, but still very secure mounting option of the retaining clip on the

Carrier plate guaranteed. In this case, the headband with the first end only anchored in the support plate, for example, be hung. This allows a simple and time-saving mounting option. According to a further embodiment, the second end region of the retaining clip with the plug-in card for fixing

locked. As a result, the headband is screwless to the carrier plate and the plug-in card fixable. For example the locking is achieved in that the headband is snapped with the second end over the edge of the Einsteckkarte, in particular the narrow side, and

positively cooperates with this.

According to a further embodiment, the headband has a main body with the first end portion and the second

Endbereich, wherein the main body along a main extension direction substantially normal to the

Support plate extends and the second end in the

Extends substantially parallel to the support plate away from the main body. The second end region has a groove for at least partially positive reception of a

Narrow side of the plug-in card.

As a result, the narrow side of the plug-in card can engage in the groove in a simple manner. The main body is

for example, pen or rod designed. As a result, the headband has only a small spatial total

Expansion, in particular parallel to the carrier sheet.

According to one embodiment, the second end region has a chamfer in the region of a free end. Preferably, the chamfer has a carrier sheet facing

Surface, wherein a distance between the surface and the carrier sheet along the direction away from the

Body of the retaining clip enlarged. By means of

Beveling can be accomplished a simple locking of the retaining clip with the plug-in card. The second end area snaps over the chamfer

Narrow side of the plug-in card. According to a further embodiment, the plug-in card is coupled via an additional plug-in card, in particular a riser card, to the plug connector of the mainboard. With such a structure, the plug-in card is more unstable in the region of the second side compared to the embodiments described above. This requires, in particular, the use of the retaining clip, whereby the plug-in card is fixed stably on the support plate. According to a further embodiment of the headband, in particular the main body of the retaining clip, height or length adjustable formed. This can be on

different arrangements, for example with or without additional plug-in card, and different heights of

Plug-in cards are responding by increasing the height

or length of the retaining clip is changed.

For example, the headband may be configured in two parts and by means of a snap closure, similar to a

Cable ties, be connected.

According to a further embodiment, the carrier plate has at least one further attachment opening for fixing a further holding bracket to the carrier plate. Of the

Retaining clip may have the embodiments described above. In such an embodiment, therefore, at least two headband are provided to secure the plug-in card to the support plate. This will be one more

achieved more stable determination of the plug-in card compared to an arrangement with only one headband.

According to a second aspect of the invention, a headband for use in a computer system according to the first Aspect revealed. The headband essentially has the abovementioned features or configurations.

The headband according to the second aspect allows in

Essentially the aforementioned advantages and functions.

Further embodiments of the invention are in the

following, detailed description of a

Embodiment with the aid of the attached

Figures described.

In the figures show:

Figure 1 is a perspective section of a

Computer system with a plug-in card and a

Headband,

Figures 2 and 3 are two perspective views of

Retaining bracket and

Figures 4 to 6 are perspective detail views of

Computer system with the headband.

FIG. 1 shows a perspective cutout of a

Computer System 1. The computer system 1 is a desktop computer system having one of the above

Clarity not shown housing. In the housing, a support plate 2 is fixed. Perpendicular to the support plate 2, a wall 3 is arranged. The wall 3 is part of a housing side of the housing. Alternatively, the wall 3 is a separate carrier sheet in the housing. On the support plate 2, a circuit board 4 is arranged parallel to this. The circuit board 4 is a system board in the embodiment (also called motherboard or motherboard). The circuit board 4 is fixed to the support plate 2. On the circuit board 4 are several connectors 5 for connecting contacts of plug-in cards. By doing

Computer system 1 is a plug-in card 6 is mounted, which is fixed in the region of a first side 7 via a slot angle 8 on the wall 3. The plug-in card 6 is in

Embodiment, a PCI card. The plug-in card 6 is electrically and mechanically coupled via a further plug-in card 10 with a connector 5 located at the edge of the printed circuit board 4. The other plug-in card 10 is a riser card. Alternatively, the plug-in card 6 is mechanically and electrically coupled directly to the connector 5 of the circuit board 4.

So that the plug-in card 6 is mechanically fixed sufficiently in the computer system 1, it is necessary that the

Plug-in card 6 in the region of a second side 9 is also secured. In the absence of such attachment, the plug-in card from the connector 5 could at least partially solve and thus lose their contact with the skin board. Next, the plug-in card 6 would float freely, especially in the region of the second side 9 and easily

can swing. This is, as mentioned above, too

avoid.

For a headband 12 is provided. The headband 12 is a simple plastic injection molded part. The mounting bracket 12 is connected to a first end portion 13 on the support plate. 2

set and surrounds with a first end portion 13 opposite the second end portion 14, the plug-in card 6 positively. Further details of the retaining clip 12 as well its attachment are described with reference to Figures 2 to 6.

Figures 2 and 3 show the headband 12 in perspective, once from diagonally above and once from diagonally below. Of the

Holding bracket 12 has an elongated, rod-shaped base body 15. In the first end portion 13 of the headband is anchor-shaped, approximately T-shaped. The main body 15 extends along a main extension direction 16. In the installed state (see Figure 1) extends the main extension direction

16 approximately normal to the support plate 2. The second end portion 14 extends perpendicular to the main extension direction 16 of the main body 15 away. A the support plate 2

facing bottom of the second end portion 14 extends approximately parallel to the support plate 2 in the mounted state. The second end region 13 has a first width 17 and a second width 18, which is greater than the first width 17, in each case perpendicular to the direction of extent of the second end region 14 away from the base body 15. In the region of the second width 18, a groove 19 is in the second

End region 14 introduced from below. In addition, at a free end of the second end portion 14, which is the

Base body 15 faces away, a bevel 20 is provided. The chamfer 20 has a support plate 2 facing, planar surface, with a distance between the

Surface and the support plate 2 in the direction away from the base body 15 increases.

For attachment of the retaining clip 12, this is hooked, as shown in Figure 4, in a mounting opening 21 of the support plate 2. The attachment opening 21 is a T-shaped recess in the carrier sheet 2. In addition, in the region of the attachment opening 21, two metal tabs of the carrier sheet 2 bent away to the anchor-shaped first

Engage behind end portion 13 in the suspended state. Between the metal tabs, the base body 15 extends from the support plate 2. As a result, the headband 12 is securely anchored to the first end portion 13 on the support plate 2.

Subsequently, the headband 12 with the second

End area 14 fixed to the plug-in card 6. In this case, the second end region 14 snaps over the plug-in card 6 and surrounds it. For this purpose, the second end portion 14 is pushed by means of the chamfer 20 via a side facing away from the support plate 2 narrow side 22 of the Einsteckkarte 6, wherein a portion of the narrow side 22 in the groove 20th

positively locked. This is shown enlarged in Figures 5 and 6. The bracket 12 must therefore hung only in the carrier plate 2 and then with the

Plug-in card 6 are locked. In addition, it can be clearly seen in FIG. 6 that the groove 20 extends beyond the one shown in FIG

Compared to the first width 17 larger second width 18 extends. Thus, the groove 20 is extended in the direction of the first side 7. As a result, slipping and falling of the retaining clip 12 is counteracted.

The headband 12 is designed such that when latching with the plug-in card 6, a mechanical tension on the

Plug-in card 6 is brought. As a result, the plug-in card 6 is held securely on the support plate 2, wherein a swinging or bending is counteracted or prevented.

In an alternative, not shown embodiment, the headband 12 is height or length adjustable in the direction of the main extension direction 16. For example the headband 12 made in two parts with a snap closure. Thus, different levels of plug-in cards can be attached to the support plate 2, wherein a height of the support bracket 12 is adjusted accordingly.
