Description

PCI Express computer expansion card socket structure

Technical Field

The application relates to the field of computers, in particular to a PCI Express computer expansion card socket structure and a PCI Express computer expansion card.

Background

The computer or the server supports the insertion of expansion cards such as network cards, audio cards, sampling cards, password cards and the like through slots of a mainboard, the most common computer expansion slot interface at present is PCI Express (PCI-E for short), and the expansion slot interface is divided into x1, x2, x4, x8 and x16 according to the number of transmission line pairs. The slots of the computer motherboard are generally four types, x1, x4, x8 and x 16. The PCI Express X1 interface expansion card has the shortest x1 slot, and the PCI Express X1 interface expansion card has the longest x16 slot, and can support four PCI Express interface expansion cards of x1, x4, x8 and x 16.

The left and right surfaces of the PCI Express slot are contact reeds, and when the expansion card is inserted, a golden finger at the socket of the expansion card can be in contact with the reeds of the slot, so that the connection of electric signals is ensured. Due to the elastic properties of the spring plate, the expansion card cannot be firmly fixed in the slot.

The fixing method of the computer expansion card is that a fixing baffle is installed at the edge of the expansion card, and when the expansion card is inserted into a computer slot, the fixing baffle can be fixed on the rear frame of the chassis of the computer host. In the case where the slot does not completely correspond to the expansion card, for example: in the case of PCI-E x1 expansion cards inserted into x8 slots, as shown in FIG. 1. Due to the single-side fixing mode, the rear surface of the expansion card is inclined outwards due to transportation, jolt, vibration and the like. A preferred method is to insert an expansion card into a mating computer slot. Namely: PCI-E x1 expansion cards are inserted into slots x1, PCI-E x8 expansion cards are inserted into slots x8, and so on, as shown in FIG. 2. Such use is referred to as "equal width splicing". The equal-width insertion enables the expansion card to be in close contact with the expansion card in the length direction through the slot, so that the expansion card can be fixed more firmly.

Because the number and the types of PCI Express sockets on a computer are limited, sockets with various sizes cannot be provided, and the PCI Express sockets can support the use of more types of plug-in cards as far as possible, more x16 sockets are generally supported on the computer, so that the PCI Express sockets can be adapted to expansion cards of x1, x4, x8 and x 16. In this case, expansion cards with less transmission lines (such as x1, x4 or x8) often use the slot of x16, which often results in loose connection.

Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Example 1

The embodiment provides a PCI Express computer expansion card socket structure, which comprises at least one fixed card position, wherein the fixed card position is arranged on a PCB (printed circuit board) of a PCI Express computer expansion card, and the sum of the width of the fixed card position and the width of an original socket on the PCI Express computer expansion card is adaptive to the width of a slot.

Specifically, in this embodiment, the PCI Express computer expansion card itself has its original socket, and the original socket is disposed on the PCB. The existing jacks may be classified into x1 jacks, x4 jacks, x8 jacks and x16 jacks according to the number of transmission lines. The greater the number of transmission lines, the greater the corresponding jack width. Thus, the socket width of the x1 socket to the x16 socket is gradually increased.

In the embodiment, at least one fixed card position is arranged on the PCB of the PCI Express computer expansion card and beside the original socket of the PCI Express computer expansion card, so that the PCI Express computer expansion card with the narrow socket is firmly inserted into the wider slot. The fixing clip position can be divided into an x4 fixing clip position 1, an x8 fixing clip position 2 and an x16 fixing clip position 3. The widths of the x4 fixing clip 1, the x8 fixing clip 2 and the x16 fixing clip 3 respectively correspond to the widths of the x4 socket, the x8 socket and the x16 socket. Therefore, when the PCI Express computer expansion card with a narrow socket is required to be inserted into a wider slot, the PCI Express computer expansion card is matched with a corresponding fixed card position only on the basis of the original socket of the PCI Express computer expansion card, so that the sum of the widths of the original socket and the fixed card position is adaptive to the width of the slot, and the PCI Express computer expansion card is firmly fixed in the slot.

In this embodiment, the fixed card positions provided on different PCI Express computer expansion cards are different according to the different original sockets of the PCI Express computer expansion card. Specifically, the method comprises the following steps:

the original socket of the PCI Express computer expansion card is an x1 socket, and a PCB of the PCI Express computer expansion card is provided with an x4 fixed card position 1, an x8 fixed card position 2 and/or an x16 fixed card position 3;

the original socket of the PCI Express computer expansion card is an x4 socket, and a PCB of the PCI Express computer expansion card is provided with an x8 fixed card position 2 and/or an x16 fixed card position 3;

the original socket of the PCI Express computer expansion card is an x8 socket, and an x16 fixed card position 3 is arranged on a PCB of the PCI Express computer expansion card.

FIG. 3 shows a conventional PCI Express computer expansion card x1 PCB socket architecture. When the PCI Express computer expansion card socket is the x1 socket, the x4 fixed position 1, the x8 fixed position 2 and the x16 fixed position 3 can be added, as shown in FIG. 4. Therefore, the PCI Express computer expansion card can be smoothly and firmly plugged into a wider slot. For example, when the conventional PCI Express computer expansion card x1 PCB socket structure shown in fig. 5 is plugged into the x8 slot, as long as the x4 fixed card 1 and the x8 fixed card 2 are retained or the x8 fixed card 2 is retained, the same plugging effect as that of the conventional PCI Express computer expansion card with the x8 socket can be achieved, that is: and (5) inserting with equal width. Similarly, when the conventional PCI Express computer expansion card x1 PCB socket structure is plugged into the x16 slot, as shown in fig. 6, as long as the x16 fixed card 3 is retained (the x4 fixed card 1 and the x8 fixed card 2 can be optionally retained), the same plugging effect as that of the conventional PCI Express computer expansion card with the x16 socket can be achieved.

FIG. 7 shows a socket structure in which x8 fixed card 2 and x16 fixed card 3 are added when the socket of PCI Express computer expansion card is x4 socket. When the PCI Express computer expansion card is inserted into the x16 slot, as shown in FIG. 8, the same plug-in effect as the conventional PCI Express computer expansion card with the x16 socket can be realized as long as the x16 fixed card 3 is reserved (the x8 fixed card 2 can be selected to be reserved or not according to the situation).

In addition, for the x16 slot, the width of the slot is larger, and the firmness requirement for the PCI Express computer expansion card is higher. Therefore, for the x16 slot, the present embodiment provides a fixed hook 5 on the x16 slot, and an x16 external fixed hook 4 matched and connected with the fixed hook 5 is provided at the edge of the PCB board of the PCI Express computer expansion card and at a position far away from the original socket on the PCI Express computer expansion card. When the PCI Express computer expansion card is plugged in the x16 slot, the x16 external fixed hook 4 is connected with the fixed hook 5 on the x16 slot, so that the PCI Express computer expansion card is plugged in the x16 slot more firmly.

In addition, in this embodiment, in order to avoid the influence of the fixing clip and the x16 external fixing hook 4 on the components on the computer motherboard, the fixing clip and the connection between the x16 external fixing hook 4 and the PCB board may be detachably connected. This detachable mode of connecting can break off with the fingers and thumb between fixed screens and the PCB board through certain external force, or can connect through the mode of buckle, or again can be through mode of pasting etc. this embodiment does not do special restriction.

Example 2

The embodiment provides a PCI Express computer expansion card, which comprises an expansion card body and a PCI Express computer expansion card socket structure, wherein the expansion card body comprises a PCB (printed circuit board) and an original socket, and the original socket and the PCI Express computer expansion card socket structure are both arranged on the PCB. The composition and principle of the PCI Express computer expansion card socket structure can refer to the content described in embodiment 1, and this embodiment is not described again.

In the embodiment, more fixed clamping positions are arranged on the basis of the original socket of the PCI Express computer expansion card, so that the effect that the width of the socket of the PCI Express computer expansion card is consistent with that of the slot can be obtained under the condition that the PCI Express computer expansion card uses more transmission line slots, and the installation of the PCI Express computer expansion card is firmer.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application.
