Description

Host

The present invention relates to a host, and more particularly to a host applied to a server system.

The motherboard in the server needs at least 10 to 12 screws for fixing. The screws can fix the motherboard to the chassis, and the static electricity on the motherboard can be transmitted to the chassis through the screws and transmitted to the earth through the chassis. To reduce electromagnetic interference.

However, the use of screws to secure the motherboard requires an increase in the cost of purchasing the screws, and the locking screws are a waste of time.

In view of the foregoing, it is necessary to provide a host that can reduce costs and reduce assembly time.

A host includes: a motherboard, the motherboard is provided with a plurality of slots, a ground tin-plated portion is disposed on a surface of each of the slotted motherboards; and a chassis, the corresponding chassis on the motherboard is opened The slot is provided with a plurality of hooks, and the hooks are snapped into the corresponding slots to fix the motherboard in the chassis, and each hook is in contact with the corresponding ground tin.

The host of the invention sets a plurality of hooks on the chassis, and correspondingly sets a plurality of hooks on the motherboard Slotting, and a grounding tin-like portion is disposed on the surface of each of the slotted motherboards, and the hook of the chassis is engaged with the slot to fix the motherboard in the chassis. The host of the invention fixes the motherboard by using the hook and the slot, so the cost of purchasing the screw and the assembly time of the locking screw can be saved. The hook is also in contact with the ground tin-soak to conduct static electricity.

Referring to Figure 1, a preferred embodiment of the host 100 of the present invention is used in a server system. The host 100 includes a chassis 10 and a motherboard 20. The motherboard 20 can be disposed within the chassis 10. An inner hook 13 of the casing 10 is provided with a plurality of hooks 11 and a screw hole 12. The corresponding hooks 11 of the motherboard 20 are provided with a plurality of slots 21. In the preferred embodiment, the slots 21 are open slots, that is, the edges of the motherboard 20 are recessed inward to form the slots 21. Each slot 21 has a size of 12 mm * 3 mm. The surface of the motherboard adjacent to each of the slots 21 is provided with a ground tin-lead portion 22 having a size of 8 mm*3 mm, and each of the ground tin-lead portions 22 can pass through a via hole (not shown). Connected to the ground plane of the motherboard 20. A through hole 23 is further disposed on the motherboard 20.

Referring to FIG. 2a and FIG. 2b together, each of the hooks 11 on the chassis 10 is a square piece which can be formed by punching during the manufacturing process of the chassis 10, so that no additional manufacturing material is required. The length of the hook 11 is smaller than the length of the slot 21 so that the hook 11 can pass through the slot 21. In this embodiment, the size of each hook 11 is high. 16mm, length 9mm. In FIG. 2a, the hook portion of the hook 11 is provided with a substantially V-shaped card slot 15 on one side of the square piece body; in FIG. 2b, the hook portion of the hook portion 11 is in the square piece body. A square card slot 16 is provided on one side. In other embodiments, the hook 11 can also have other shapes.

In actual assembly, the slot 21 of the motherboard 20 is opposite to the hook 11 on the chassis 10, and the hook 11 is passed through the slot 21 of the motherboard 20 so that the edge of the motherboard 20 is facing the card. The card slot 15 of the hook 11 pushes the motherboard 20 laterally so that the motherboard 20 snaps into the slot of the hook 11 , and each slot abuts the ground tin portion 22 disposed adjacent to the corresponding slot 21 . The plurality of hooks 11 on the chassis 10 are latched with the motherboard 20 such that the motherboard 20 is fixed to the chassis 10. Since the hook 11 is in contact with the ground tin-lead portion 22 of the motherboard 20, the static electricity on the motherboard 20 is transmitted to the ground through the ground tin-lead portion 22 to eliminate electromagnetic interference on the motherboard 20 and Increase the ability to prevent electrostatic discharge.

Alternatively, a screw 24 can be screwed into the screw hole 12 through the through hole 23 to reinforce the fixing force for fixing the motherboard 20 to the chassis 10. The through hole 23 can be disposed at a central position of the motherboard 20.

Referring to FIG. 3 together, the slot 21 can also be a closed slot, that is, an elongated hole is formed near the edge of the motherboard 20 to form the slot 21 . The ground tin-lead portion 22 can also be welded to a metal elastic piece 25 having a size of 8 mm long, 3 mm wide, and 1 mm high for increasing the contact area of the ground tin-lead portion 22 and the hook 11. Further, since the metal dome 25 has elasticity, the tightness and the fixing force between the hook 11 and the motherboard 20 can be enhanced.

The host 100 of the present invention is provided with a plurality of hooks 11 through punching on the chassis 10, and a plurality of slots 21 are correspondingly arranged on the motherboard 20, and adjacent to each slot 21 The surface of the motherboard 20 is provided with a ground tint portion 22, and the hook 11 of the chassis 10 is in contact with the grounding tin portion 22 of the motherboard 20 through the slot 21, and the motherboard 20 is clamped to the chassis. Within 10. The host 100 of the present invention can fix the motherboard 20 to the chassis 10 without the use of screws 24 or with only one screw 24, which saves the cost of purchasing the screws 24 and reduces the time required to install the motherboard 20.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
