Telescopic screw fitting and main board combination structure using same

The present invention relates to a motherboard assembly structure, and more particularly to a telescopic screw assembly and a motherboard assembly structure using the same.

Generally, the main board is usually installed inside the server main body (or server). However, since the surface of the main board has many electronic parts, it is easy to be damaged due to the touch. Therefore, the main board is usually installed. The handle allows the assembler to hold the handle when installing or removing the motherboard to prevent the motherboard from directly touching the electronic components and causing damage to the motherboard.

However, since the server host has a certain internal space, and many electronic components (such as PCIe cards and RAID cards, etc.) must be installed on the motherboard and covered by the handle, the height of the handle is limited (usually 11mm or less). The average person's finger size is about 15~20mm, so it is easy to cause difficulty in grasping. On the contrary, it is easy to fall during the process of moving the motherboard.

In addition, although the manufacturer uses the screw on the motherboard to loosen the screw to adjust the height of the screw head so that the hand can be easily grasped, this method must be used every time the motherboard is installed or removed. The tool causes inconvenience in assembly and reduces work efficiency.

In view of the above problems, the present invention provides a motherboard assembly structure including a motherboard, a carrier, and a telescopic screw. The motherboard includes a first side, a second side, and a through hole, and the through hole penetrates the first side and the second side.

The main body is connected to the main board, and the screwing hole is disposed through the main body and communicates with the through hole of the main board. The handle comprises a holding end, an inner groove and a through hole, wherein the inner groove is recessed on the holding end, wherein the inner groove has a non-circular cross section and comprises a bottom wall and a peripheral side wall, wherein the through hole is at the bottom a wall, and a limited portion is formed between the through hole and the peripheral side wall. The screw comprises a rod body, an external thread portion and a screw head. The external thread portion is located at one end of the rod body, and the screw head portion is located at the other end of the rod body, and the cross section of the screw head corresponds to the shape of the inner groove, wherein the outer portion The threaded portion is sequentially passed through the inner groove, the through hole and the screw hole, and is screwed and positioned on the inner screw hole, so that the limiting portion of the handle is telescopically abutted against the connecting post in the first position, or is abutted against The head is in the second position.

Wherein, the cross-sectional profile of the inner groove and the screw head may be polygonal, elliptical or have a convex portion, and this portion is not limited.

With the above structure, the telescopic screw member can be completed without using any hand tool in the process of assembling the main board and the carrier or disassembling. In addition, if the motherboard is to be grasped, the handle can be telescopically adjusted to the second position to increase the distance between the handle and the motherboard, so that the user can hold the grip by hand, and assemble electronic components (such as PCIe). Cards, RAID cards, etc.) When the motherboard is used, the handle can be telescopically adjusted to the first position to reduce the distance between the handle and the motherboard, so that the electronic components can be smoothly mounted on the motherboard in a limited cabinet space. .

With the above structure, the following is a description of the combined process of the creation:

Referring to FIG. 5 , first, the assembler can first fix the connecting post 10 to the motherboard 40 , and the screw hole 12 and the through hole 43 communicate with each other, and then the external thread portion 32 of the screw 30 passes through the inside of the handle 20 . The groove 22 and the through hole 23, and then as shown in FIG. 6, the external thread portion 32 is passed through the screw hole 12 and abuts against the inner screw hole 52 through the rotating screw head portion 33, thereby forming the upward degree of freedom of the handle 20. The screw head 33 is located in the inner recess 22, and the screw head 33 and the inner recess 22 are in a non-circular shape, so that the handle 20 can be rotated to drive the screw head 33 to rotate. The external thread portion 32 is locked to the inner screw hole 52 of the carrier 50, whereby the main plate 40 and the carrier 50 are combined with each other through the telescopic screw 1 as shown in FIG. The limiting portion 223 is telescopically abutted against the connecting post 10 in the first position, or, as in Fig. 8, is in the second position against the screw head 33. Thereby, the telescopic screw 1 can be completed without using any hand tools during the process of assembling the main board 40 and the carrier 50 or disassembling, thereby achieving the effect of greatly improving work efficiency. In addition, when the assembler wants to grab the motherboard 40, the handle 20 can be telescopically adjusted to the second position (as shown in FIG. 8) to increase the distance between the handle 20 and the motherboard 40, which is convenient for the user's hand. Grab the grip, and when assembling the electronic components (such as PCIe card and RAID card, etc., as shown in Figure 1) on the motherboard 40, the handle 20 can be telescopically adjusted to the first position (as shown in Figure 7). Shown) to reduce the distance between the handle 20 and the motherboard 40 so that the electronic components can be smoothly mounted on the motherboard 40 in a limited cabinet space.

In addition, as shown in FIG. 7 , in this embodiment, the connecting post 10 can include a slot 13 , the slot 13 and the screwing hole 12 communicate with each other, and the slot 13 is opposite to the screw head 13 with respect to the screwing hole 12 . . The width of the slot 13 is greater than the width of the screw hole 12, so that the external thread portion 32 can pass through the slot hole 12 and then pass through the slot 13 to be screwed and positioned in the inner screw hole 52. In addition, the slot 13 The height distance can be greater than the length of the external thread portion 32, so that the external thread portion 32 can pass through the screw hole 12 to have a space for up-and-down movement adjustment, so that the screw head portion 33 can be placed into the inner groove 22 more smoothly.

As shown in FIG. 7 , the handle 20 further includes a connecting end 26 with respect to the grip end 21 , and the connecting end 26 can be provided with a ring protrusion 27 . When the handle 20 is in the first position, the ring protrusion 27 corresponds to The abutment state of the handle 20 and the connecting post 10 is made more stable by the abutment portion 14.

The screw 30 further includes a positioning protrusion 34 connected to the rod body 31 and located between the external thread portion 32 and the screw head 33 to position the protrusion 34 and abut against the connecting post 10, thereby preventing the screw 30 continues to spiral out of the inner screw hole 52, and the connecting post 10 can be fixed to the main board 40.

In summary, the creation of the telescopic screw fitting can be completed without any hand tools during the process of assembling the main board and the carrier or disassembling. In addition, if the motherboard is to be grasped, the handle can be telescopically adjusted to the second position to increase the distance between the handle and the motherboard, so that the user can hold the grip by hand, and assemble electronic components (such as PCIe). Cards, RAID cards, etc.) When the motherboard is used, the handle can be telescopically adjusted to the first position to reduce the distance between the handle and the motherboard, so that the electronic components can be smoothly mounted on the motherboard in a limited cabinet space. .
