Description

The present disclosure relates to motherboard assemblies and, more particularly, to motherboard assemblies that include at least one shield.

Generally, when assembling a computer, it is necessary to attach an I/O shield to the computer case before attaching the motherboard to the computer case. To simplify computer assembly, some manufacturers may attach the I/O shield to a fin assembly on the motherboard. This method allows the I/O shield and motherboard to be attached to the computer case together in a single step.

However, the size and location of the fin assembly may change depending on the use of the motherboard. As such, the fin assembly on the motherboard may be far away from the I/O shield, or may be small in size and not located adjacent to the I/O shield. Therefore, it is difficult to mount the I/O shield to the motherboard via the fin assembly. In summary, it is difficult to simplify computer assembly while allowing I/O shields to be implemented on motherboards of different specifications.

The present disclosure provides a motherboard assembly that simplifies computer assembly while allowing shields to be implemented on circuit boards of different specifications.

One embodiment of the present disclosure provides a motherboard assembly that includes a circuit board, at least one connector, a shield, and a first limiting component. At least one connector is disposed on the circuit board and has a port. The shield has at least one opening. A port of at least one connector is exposed through the at least one opening. Two different sides of the first restriction piece are each fixed to at least one connector and a shield.

According to the motherboard assembly disclosed by the above embodiments, two different sides of the first limiting component are fixed to the connector and the shield, respectively. Also, the port of the connector is exposed through the opening in the shield. Therefore, by locating the connector adjacent to the shield, it becomes possible to fix the shield to the connector via the first limiting component regardless of the specifications of the circuit board. Therefore, restrictions caused by fixing the shield to the circuit board via the fin assembly can be avoided. Therefore, assembly of the computer can be simplified while allowing the shield to be mounted on circuit boards of different specifications.

Further embodiments are described below for purposes of illustration. In the following embodiments, some of the reference numerals and contents of the above-described embodiments are used, the same or similar elements are given the same reference numerals, and the description of the same technical contents is omitted. Regarding the explanation of the omitted parts, the above-described embodiments can be referred to, and detailed explanations will be omitted in the following embodiments.

The present disclosure is not limited by the configuration of the second limiting component. Please refer to FIGS. 10 and 11. FIG. 10 is an exploded view of a motherboard assembly 10a according to a second embodiment of the present disclosure. FIG. 11 is a sectional view showing the motherboard assembly 10a of FIG. 10 mounted in the case 20. The only difference between the motherboard assembly 10a of this embodiment and the motherboard assembly 10 of the first embodiment is that the second limiting component 600a of this embodiment is a fastening pin. Specifically, in this embodiment, the second limiting component 600a is disposed through the second mounting protrusion 330 and the circuit board 100, and between the second limiting component 600a and the second mounting protrusion 330.

According to the motherboard assembly disclosed by the embodiments described above, two different sides of the first limiting part are fixed to the connector and the shield, respectively. Additionally, the port of the connector is exposed through the opening in the shield. The connector is therefore placed adjacent to the shield, thereby allowing the shield to be fixed to the connector via the first limiting member, regardless of the specifications of the circuit board. Therefore, restrictions caused by fixing the shield to the circuit board via the fin assembly can be avoided. Therefore, assembly of the computer is simplified while allowing the shield to be mounted on circuit boards of different specifications.

Additionally, the connector is disposed between at least a portion of the first limiting component and the circuit board. That is, the first limiting component is fixed to the top surface of the connector located farthest from the circuit board. Therefore, regardless of the number and size of connectors on the circuit board, the shield can be fixed to the connectors via the first limiting part. In particular, in low-end computers, the height of the connector relative to the circuit board is low, so even if it is difficult for the first limiting component to be fixed to the side surface of the connector, the first limiting component fixed to the top surface of the connector may be difficult to fix. The shield can be firmly fixed to the connector through the connector.

Various modifications and variations of this disclosure will be apparent to those skilled in the art. It is intended that the specification and examples be considered as exemplary embodiments only, with the scope of the disclosure being indicated by the following claims and their equivalents.
