Description

Expansion module and its framework

The present invention relates to an expansion module and a frame thereof, and more particularly to an expansion module of an interface card and a frame thereof.

With the evolution of computer technology, interface cards such as network interface cards and video interface cards used in general computers are often electrically connected to the computer motherboard by using the interface card expansion slot of the Personal Computer Interface (PCI). In addition to PCI, the interface card expansion slot standard that has been widely used includes PCI-X, PCI-E (PCI Express), SATA (Serial Advanced Technology Attachment), SCSI (Small Computer System Interface), and dedicated notes. Different types of standards such as MINI PCI-E (MINI PCI Express) are used in the computer. Therefore, the interface card expansion slot has become an essential accessory for current computer motherboards.

At present, most of the conventional interface cards are set and fixed in the interface card expansion slot of the computer motherboard in a horizontal manner, but the horizontal setting manner is likely to cause the interface card to shield the excessive area of the motherboard, so that the motherboard is available for other purposes. The area of the electronic component insertion is reduced, or the slot originally reserved for other electronic components on the motherboard cannot be used normally due to the shielding of the interface card.

In addition, in order to increase the space utilization of the motherboard, some computer hosts use a vertical interface to set the interface card on the motherboard, and to avoid shaking or loosening the interface card. One end of the interface card is inserted outside the interface card expansion slot, and the other end of the interface card is locked to a frame with a screw to further fix the interface card. However, in the frame for fixing the interface card, the stud for locking the screw and the frame of the frame are combined with each other by punching, so that the stud is pressed in a tight fit manner. In the assembly hole of the frame. Therefore, in the process of pressing, if the stamping of the stud is not complete or offset, it will cause the stud to easily sway or loosen on the frame, seriously affecting the yield of the product, and assembling the frame at the same time. In the process of the motherboard or the locking interface card, the stud is easily detached due to the impact of the external force, and the purpose and function of the originally intended fixed interface card cannot be achieved. In addition, in addition to the above-mentioned frame, the yield of the product is easily affected, and the production of the conventional frame requires the use of different components and additional stamping procedures, resulting in a problem of high production cost of the conventional frame.

In view of the above problems, the present invention provides an expansion module suitable for a fixed interface card and a frame thereof, thereby solving the problem that the horizontal interface card setting manner causes the area of the motherboard to be inserted into other electronic components to be reduced, or the original The slot reserved for other electronic components cannot be used normally due to the shielding of the interface card, and the stud of the frame of the conventional interface card expansion module is liable to be loose on the frame or impacted by external force. Falling off, causing the interface card to not be fixed properly.

The invention discloses an expansion module, which is suitable for an interface card, and the interface card is electrically connected to a circuit board through the expansion module. The expansion module includes a frame with an electrical connector. One side of the electrical connector is electrically disposed on the circuit board, and the electrical connector forms an electrical socket with respect to the other side of the circuit board. The frame includes an integrally formed body, at least one holding portion and at least one fastening portion, and the holding portion and the fastening portion of the frame are respectively connected to opposite sides of the body, and the frame is The holding portion is detachably disposed on a side of the circuit board adjacent to the electrical connector, and the fastening portion of the frame corresponds to an electrical socket of the electrical connector, wherein one end of the interface card is electrically inserted into the electrical connector The slot and the other end of the interface card are detachably fixed to the fastening portion of the frame.

The present invention also discloses a frame for fixing an interface card to a circuit board, and an electrical connector is electrically disposed on the circuit board. The frame includes a body, two holding portions and at least one fastening portion. The body is disposed on the circuit board and extends along a normal direction of the circuit board. The two holding portions are integrally formed on the body, and the body is disposed on the circuit board through the two holding portions. The fastening portion is integrally formed on one side of the body away from the two holding portions, and the fastening portion corresponds to the electrical connector, wherein one end of the interface card is electrically inserted into the electrical connector, and the other end of the interface card corresponds to a fastening portion and is fixed to the fastening portion.

The utility model has the advantages that the interface card is formed by forming an electrical socket of the electrical connector on one side of the electrical connector away from the circuit board, and placing the frame on the circuit board and extending along the normal direction of the circuit board. One end is electrically inserted into the electrical slot, and when the other end is detachably fixed to the fastening portion of the frame, the device can be electrically disposed on the circuit board in an upright manner, thereby reducing the interface on the circuit board. The area occupied, which in turn increases the area of use of electronic components on the surface of the board. Moreover, by forming the fastening portion on the body of the frame in an integrally formed manner by the frame, the loosening between the fastening portion and the body can be avoided, so that when the interface card is locked to the fastening portion of the frame by the fixing member, It will enable the interface card to be more firmly fixed to the frame without sloshing or loosening due to external impact, greatly improving the fixing effect of the interface card, reducing the production cost of the frame and improving the production efficiency.
