Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a section rack for storing a plurality of section rack boards (printed boards).

[0002]

2. Description of the Related Art FIG. 7 is a perspective view showing a conventional section rack. In this figure, a plurality of guide rails 2 are provided on the upper and lower surfaces inside the partitioned rack body 1 along the longitudinal direction of the partitioned rack body 1 so that the upper surface side and the lower surface side face each other. In this case, each guide rail 2
It is provided so as to bridge between the opening side in the depth direction of the section rack main body 1 (that is, the insertion side of the section rack board 6) and the guide rail mounting portions 3 provided on the back side.

A guide rail 2 guides a partition rack board 6 to a card edge connector 5 mounted on a motherboard 4 attached to the rear surface of the partition rack main body 1. A partition rack is provided between upper and lower guide rails 2 facing each other. The connector portion 6A of the partitioned rack substrate 6 can be fitted into the card edge connector 5 of the motherboard 4 by strongly pressing the board 6 through the substrate 6 and reaching the motherboard 4. Thereby, the partition rack board 6 and the motherboard 4 are electrically connected. The motherboard 4 is shown in FIG.
As shown in the figure, the partition rack body 1 is directly attached to the partition rack body 1 with a plurality of screws 8 from behind.

[0004]

However, the above-described conventional partition rack has the following problems. (A) Since the section rack requires a high level of dimensional accuracy due to the sheet metal structure (welding, screwing), if an error occurs in the dimensional accuracy in the manufacturing stage, the guide rail 2 is required.
Is not aligned with the position of the card edge connector 5 of the motherboard 4, and the partition rack substrate 6 is
Sometimes it was difficult to connect.

(B) Since the motherboard 4 is directly attached from the rear of the partition rack with the screws 8, the pressing force applied to the motherboard 4 when connecting the partition rack substrate 6 to the motherboard 4 is concentrated on the screws 8, and The nearby motherboard 4 could be damaged. (C) Since the fixing with the screws 8 is performed at points, the portion between the screws of the motherboard 4 is deformed when the partitioned rack substrate 6 is connected to the motherboard 4, and adversely affects the substrate such as round peeling and pattern cutting. There was a fear of giving.

Accordingly, the present invention can easily and reliably insert the partition rack board into the card edge connector of the motherboard without increasing the dimensional accuracy of the partition rack, and break the motherboard when the partition rack board is inserted. It is an object of the present invention to provide a partition rack that does not deform or deform.

[0007]

In order to achieve this object, a partition rack according to the present invention is mounted along the longitudinal direction of the partition rack body so as to face the upper and lower surfaces of the inside of the partition rack body. A plurality of guide rails for guiding the board in the depth direction in the compartment rack main body, and a motherboard attached to a back surface of the compartment rack main body and having a plurality of card edge connectors attached thereto for connecting to a connector portion of the compartment rack board. And a bar-shaped main body having a length substantially the same as the length of the motherboard in the longitudinal direction, a part of which is formed flat along the longitudinal direction, and a flat surface of the main body. A flat bar-shaped holding portion having a thickness smaller than the width of the flat surface and having the same thickness as the thickness of the motherboard. A partition rack main body having two mother board fixing members having screw holes formed at the same positions on both ends of the main body portion and the holding portion, and holding the mother board fixing members with the holding portions facing the partition rack main body side. In this case, both ends of the mother board in the longitudinal direction are sandwiched between the motherboard and the partition rack main body.

According to this structure, when the partition rack board is passed through the guide rail in the partition rack body and connected to the motherboard, the motherboard fixing member is temporarily fixed to the partition rack body with the screws loosened in advance. Then, in this state, the left and right positions of the motherboard are adjusted so that the connector portion of the partition rack board passed through the guide rail matches the position of the card edge connector of the motherboard. After making this adjustment, the motherboard is fixed to the partition rack body by completely tightening the screws. Thereby, even if the direction of the guide rails and the position of the card edge connector are shifted, it can be corrected by shifting the motherboard in the left-right direction, and the partitioned rack board can be easily and reliably connected to the motherboard. .

In addition, since the motherboard is not fixed directly with screws but is fixed by sandwiching it with a motherboard fixing member, it is fixed not by a point but by a surface. Therefore, when the partition rack board is inserted into the card edge connector of the motherboard. The pressure applied to the motherboard can be dispersed, and the motherboard can be prevented from being deformed or damaged, and the reinforcement of the motherboard can be enhanced.

[0010] The main body of the motherboard fixing member may be formed in an L-shaped cross section, and the holding portion of the motherboard fixing member may be provided on the flat surface. By making the shape of the main body part L-shaped in cross section, it becomes strong against bending,
Even with the same strength, the wall thickness can be reduced as compared with the case where a flat plate is used.

A main body portion 12A having a length substantially equal to the length in the longitudinal direction and having an L-shaped cross section is provided on a flat surface of the main body portion 12A, and is formed flat. A flat bar-shaped holding portion 12B having a width smaller than the width of the surface and having the same thickness as the thickness of the motherboard 11. The above-described screw holes 12C are formed at the same positions on both ends of the main body portion 12A and the holding portion 12B.

The holding portion 12B of the motherboard fixing member 12
3 is narrower than the main body 12A and the thickness is the same as that of the motherboard 11, so that both ends of the motherboard 11 in the longitudinal direction are sandwiched between the main body 11 and the partitioned rack main body 10 as shown in the sectional view of FIG. can do. in this case,
Since the motherboard 11 is not directly fixed with the screws 13 but is fixed by sandwiching it between the motherboard fixing member 12 and the partitioning rack main body 10, the partitioning rack substrate 6 can be fixed not by dots but by a surface. The pressure applied to the motherboard 11 when inserted into the card edge connector 5 can be dispersed, and the motherboard 11 is not deformed or damaged.
The reinforcement property for is increased. Further, by forming the main body 12A of the motherboard fixing member 12 into an L-shaped cross section,
It becomes stronger against bending, and the thickness can be reduced as compared with a flat plate with the same strength.

FIG. 4 shows the motherboard fixing member 12.
FIG. 5 is a perspective view showing a state in which the motherboard 11 is attached to the partition rack main body 10 according to the present invention, and FIG. 5 is a perspective view showing a connection state between the partition rack board 6 and the motherboard 11. FIG. 6 is a perspective view showing an example of a state where the partition rack is attached to the housing 20.

When a plurality of partition rack boards 6 are connected to the motherboard 11 through the guide rails 2 in the partition rack body 10, the motherboard fixing members 12 are temporarily fixed to the partition rack body 10 with the screws 13 loosely tightened. In this state, the left and right positions of the motherboard 11 are adjusted so that the connector 6A of the partition rack board 6 passed through the guide rail 12 matches the position of the card edge connector 5 of the motherboard 11. After this adjustment, the motherboard 11 is fixed to the partition rack body 10 by completely tightening the screws 13. Thereby, even if the direction of the guide rail 2 and the position of the card edge connector 5 are shifted, it can be corrected by shifting the motherboard 11 in the left-right direction, and the partition rack board 6 can be easily and reliably connected to the motherboard 11. be able to.
