[0048] The present application discloses an airborne electronic equipment cabinet.

[0049] Please refer to Figures 3-7 As shown in the figure, the airborne electronic equipment cabinet comprises a cabinet 1, a cabinet cover 2 and a movable board card 3.

[0050] The cabinet 1 is a hollow structure with one end open, for inserting the movable board card 3 therein. The inner cavity of the cabinet 1 is provided with a sliding groove 11, which is suitable for sliding fit with the movable board card 3. The end of the inner cavity of the cabinet 1 away from the opening is provided with a fixed board card 4. In the present embodiment, the end of the fixed board card 4 away from the opening of the cabinet 1 extends to the outside of the cabinet 1. The cabinet cover 2 is detachably mounted at the opening of the cabinet 1, for sealing the opening of the cabinet 1. The outer side of the cabinet cover 2 is provided with a handle 21 for carrying.

[0051] The connecting piece 5 is mounted at the plug-in end of the movable board card 3. The connecting piece 5 is adapted to be placed outside the fixed board card 4 when the plug-in end of the movable board card 3 is plugged into the fixed board card 4.

[0052] An operation hole 12 is formed on the side wall of the cabinet 1. In the present embodiment, the operation hole 12 is a long waist hole. The length direction of the operation hole 12, the plug-in direction of the movable board card 3 and the length direction of the sliding groove 11 are consistent. The operation hole 12 is adapted to expose the connecting piece 5 outside the cabinet 1 (as shown in Figure 4 The figure) when the plug-in end of the movable board card 3 is plugged into the fixed board card 4, so as to separate the movable board card 3 from the fixed board card 4 by operating the connecting piece 5.

[0053] Specifically, when the active board card 3 needs to be inserted into the fixed board card 4, the active board card 3 is inserted into the inner cavity of the box body 1 along the sliding groove 11 and is connected to the fixed board card 4. When the active board card 3 needs to be pulled out of the box body 1, the auxiliary rod is inserted through the operation hole 12 so that the auxiliary rod is connected to the connecting piece 5. Then, the auxiliary rod is driven to move away from the fixed board card 4, so that the auxiliary rod drives the corresponding active board card 3 to move away from the fixed board card 4 through the connecting piece 5, and then the active board card 3 is separated from the fixed board card 4, so that the active board card 3 is taken out of the box body 1 by the worker.

[0054] In this embodiment, the box body does not use the puller, and the active board card 3 does not need to be provided with the pull hole, so the structure is simple. Please refer to FIG. 1 and FIG. 2. Figure 4 and Figure 6 As shown in FIG. 1 and FIG. 2, the connecting piece 5 is provided with a connecting hole 51. The axis of the connecting hole 51 is perpendicular to the insertion direction of the active board card 3. The operation hole 12 is suitable for exposing the connecting hole 51 outside the box body 1 when the insertion end is connected to the fixed board card 4. Specifically, when the insertion end of the active board card 3 is connected to the fixed board card 4, the auxiliary rod can pass through the operation hole 12 and the connecting hole 51 in sequence, so that the auxiliary rod can more effectively drive the active board card 3 to move.

[0055] Further, in order to ensure that the auxiliary rod can smoothly drive the active board card 3 to move, a plurality of connecting pieces 5 (as shown in FIG. 1 and FIG. 2) are arranged on the same active board card 3. Figure 5 The plurality of connecting pieces 5 are arranged on the same active board card 3 in a direction perpendicular to the insertion direction of the active board card 3, that is, the plurality of connecting pieces 5 are arranged in the axial direction of the connecting hole 51.

[0056] In this embodiment, the connecting piece 5 includes but is not limited to a ring-shaped clamp. Preferably, the connecting piece 5 is a ring-shaped clamp, which is a standard part in the aviation industry and has a lower cost than the puller.

[0057] In this embodiment, the box body 1 has a first side plate and a second side plate arranged opposite to each other, and the first side plate and the second side plate are parallel to each other. The operation hole 12 is arranged opposite to each other on the first side plate and the second side plate. When the insertion end of the active board card 3 is connected to the fixed board card 4, the active board card 3 is arranged between the first side plate and the second side plate and is perpendicular to the first side plate. The operation hole 12 can be used to expose the connecting piece 5 and can also be used to dissipate heat from the inner cavity of the box body 1.

[0058] Please refer to FIG. 1 and FIG. 2. Figure 3As shown, the first side plate and the second side plate are further provided with heat dissipation holes 13. The heat dissipation holes 13 provided on the side plates of the box body 1 are prior art structures. On the basis of the prior art structure, we expand part of the heat dissipation holes 13 to operation holes 12 by fine-tuning the openings of the first side plate and the second side plate on the box body 1, and increase a connecting piece 5 at the connecting position of the first connector 32 of the movable board card 3, so as to realize the structure design of assisting the pulling of the movable board card 3. In addition, the heat dissipation holes 13 and the operation holes 12 are arranged on the same side plate to prevent the distribution of the operation holes 12 from affecting the overall aesthetics of the box body 1.

[0059] Further, please refer to Figure 7 As shown, the inner sides of the first side plate and the second side plate are oppositely provided with sliding grooves 11. The inner sides of the first side plate and the second side plate are respectively provided with a plurality of equidistantly arranged guide rails 14. The length direction of the guide rails 14 is consistent with the plug-in direction of the movable board card 3. On the first side plate, the sliding groove 11 is formed between the two adjacent guide rails 14. On the second side plate, the sliding groove 11 is formed between the two adjacent guide rails 14. The sliding grooves 11 on the first side plate and the sliding grooves 11 on the second side plate are oppositely distributed. When the movable board card 3 is inserted into the inner cavity of the box body 1 along the sliding grooves 11, the sliding grooves 11 on the first side plate and the sliding grooves 11 on the second side plate are respectively slidably connected with the edges of the movable board card 3, thereby ensuring the smooth sliding of the movable board card 3 in the box body 1 and improving the stability of the structure.

[0060] Please refer to Figure 6 As shown, the movable board card 3 comprises a main board 31 and a first connector 32. The first connector 32 is arranged on the plug-in end of the main board 31.

The connecting piece 5 and the first connector 32 are assembled on the main board 31 by using the same connecting bolt 33. The connecting piece 5 and the first connector 32 share the same connecting bolt 33, without additional fasteners, so that the structure is simple, and the new technical solution of the present application can be realized by fine-tuning the existing airborne electronic equipment case. In the process of pulling out the movable board card 3, the structure indirectly applies force to the first connector 32, thereby avoiding the problem of damage to the movable board card 3 or other devices in the process of pulling out the movable board card 3 by lead wires or with the help of a puller.

[0061] In this embodiment, the four active board cards 3 are respectively a power board card, an IO board card, a CPU board card and an AI board card. Each of the active board cards 3 is provided with two connecting pieces 5 and two connecting bolts 33, and the connecting pieces 5 and the connecting bolts 33 are in one-to-one correspondence. The connecting mode between the connecting piece 5, the first connector 32 and the main board 31 includes but is not limited to the following two modes. Mode one, the connecting bolt 33 sequentially passes through the corresponding connecting piece 5 and the main board 31, and is threadedly connected with the first connector 32. Mode two, the connecting bolt 33 sequentially passes through the corresponding connecting piece 5 and the first connector 32, and is threadedly connected with the main board 31.

[0062] Further, please refer to Figure 5 As shown in the figure, the main board 31 is provided with a locking strip 34. The main board 31 is adapted to cooperate with the corresponding sliding groove 11 through the locking strip 34. The locking strip 34 is prior art. The Chinese patent document with the publication number CN214708390U discloses a printed circuit board locking device. The document details how the printed circuit board is installed on the slot structure through the wedge-shaped locking strip. Therefore, the locking strip 34 will not be described in detail.

[0063] Please refer to Figure 6 As shown in the figure, the fixed board card 4 is provided with a second connector 41 on the side close to the opening of the box body 1, and the second connector 41 is adapted to be inserted with the first connector 32 of the active board card 3. The other side of the fixed board card 4 is provided with a third connector 42. The third connector 42 extends to the outside of the box body 1 and is adapted to be connected with the cable outside the box body 1.

[0064] In this embodiment, the fixed board card 4 is a bus board. The fixed board card 4 includes a first board card 43 and a second board card 44. The first board card 43 and the second board card 44 are spaced apart along the insertion direction of the active board card 3. The first board card 43 is arranged between the second board card 44 and the active board card 3. The second board card 44 is installed on the box body 1 through the second isolation column 47, a screw and a gasket, and the second board card 44 is spaced apart from the box body 1.

The first board card 43 is fixed on the second board card 44 through the first isolation column 46, a screw and a gasket, and the first board card 43 is spaced apart from the second board card 44. The second connector 41 is arranged on the side wall of the first board card 43 away from the second board card 44. The first board card 43 and the second board card 44 are connected with an FPC flexible circuit board 45.

[0065] Preferably, the first isolation column 46 and the second isolation column 47 are both hexagonal internal thread isolation columns.

[0066] In the on-board electronic equipment case, the pulling steps of the active board card 3 are as follows:

[0067] First, the box cover 2 is detached from the box body 1;

[0068] Adjust the locking strip 34 on the movable board card 3 using a screwdriver, so that the locking strip 34 is no longer locked with the sliding groove 11;

[0069] Pass the auxiliary rod through the operation hole 12, so that the auxiliary rod is connected with the connecting piece 5 arranged on the movable board card 3, drive the auxiliary rod to move away from the fixed board card 4, so that the auxiliary rod drives the corresponding movable board card 3 to move away from the fixed board card 4 through the connecting piece 5, and then the movable board card 3 is separated from the fixed board card 4, so that the worker takes out the movable board card 3 from the box body 1, and then realizes the pulling out of the movable board card 3.

[0070] In general, the utility model discloses a operation hole is set up on the box body, and the connecting piece is arranged on the plug-in end of the movable board card, so that the safe plug of the movable board card is realized.
