Board positioning structure
This creation is about a positioning structure, especially a positioning structure applied to a circuit board.
In today's technology and information continues to thrive, computer equipment is already quite popular electronic devices. The computer equipment currently on the market, whether it is a desktop computer, a notebook computer, or a server, must be equipped with a motherboard inside as a core component of the computer system, so that it is electrically connected to the motherboard. Computer peripheral hardware such as a central processing unit (CPU), a memory module, and a control interface card (PCI card) can smoothly perform the preset functions of the peripheral hardware.
Generally, a common method of fixing a motherboard is to set a plurality of conductive copper pillars as a fixing member on a casing of the computer device, and a plurality of through holes corresponding to the copper pillars are opened on the motherboard. The motherboard is placed on the copper column and maintained at an appropriate distance from the housing, and then through a plurality of bolts respectively through the through hole of the motherboard, and locked on the copper column, so that the motherboard is made of copper The column generates a suspension to prevent the solder joint of the back of the motherboard from directly contacting the housing and causing a short circuit.
In the traditional way of locking and fixing the main board by the copper column, the user must perform the bolt locking and unloading action one by one and repeatedly in the process of loading and unloading the main board, which is quite time consuming and complicated in operation, and is not convenient in practical use. . Moreover, current electronic devices are required to be thin and light, and the number of excessive copper pillars will occupy too much area of the motherboard, resulting in difficulty in circuit layout on the motherboard, and the overall size of the electronic device cannot be miniaturized.
Therefore, in recent years, a thumb screw that can be directly rotated by a finger has been developed as a positioning member for fixing a main board, thereby greatly reducing the number of copper posts used, thereby solving the problem of fixing the main board by the copper column lock. The problem that arises. Please refer to "Figure 1" for a three-dimensional exploded view of the thumb screw, circuit board and casing in the prior art. The housing 10 has a plurality of positioning posts 11 and a screw hole 61. A neck portion 12 is defined in the upper portion of each positioning post 11. The circuit board 20 is provided with a plurality of positioning holes 21 corresponding to the positioning posts 11. Each positioning hole 21 has a gourd shape and has a wide section 22 and a narrow section 23, and the front end of the positioning post 11 passes through the positioning hole 21 by the wide section 22. Thus, the circuit board 20 can slide on the casing 10 by the positioning post 11 and the narrow section 23 of the positioning hole 21 is embedded in the neck portion 12 of the positioning post 11. Thereafter, the circuit board 20 can be fixed to the casing 10 by passing the thumb screw 60 through the circuit board 20 and screwing it into the screw hole 61.
However, the use of the thumb screw to fix the motherboard is still a screw-locking method. The process of loading and unloading the motherboard is complicated, not only takes too long, but also the cost of the thumb screw is higher than the price of the traditional bolt, thus resulting in Material costs and labor costs increase. Therefore, how to truly implement the mounting position of the motherboard in a screwless manner and to facilitate the quick and easy loading and unloading of the motherboard by the user are problems that those skilled in the related art are currently trying to overcome.
In view of the above problems, the present invention provides a circuit board positioning structure for improving the prior art to screw and unload a motherboard, resulting in an electronic device that cannot be miniaturized in size, and the loading and unloading process is cumbersome and time consuming, and requires a tool to be locked. The manufacturing cost is too high, and it is inconvenient for the user to operate.

Wherein, the positioning component further comprises a cylinder and a fastening portion disposed at one end of the cylinder, the cylinder passing through one of the perforations of the circuit board and rotating in the perforation, so that the positioning member has a cylinder extending into the hollow seat and buckled The retaining portion abuts against the first position of the stop member, and the post is disengaged from the hollow seat and the latching portion is moved away from the second position of the stop member. In this way, the circuit board can be fixed to the housing.
The effect of the present invention is that when the circuit board is moved to the bonding position, the positioning member can be moved up and down and rotatable by the positioning mechanism of the circuit board, that is, the cylinder of the positioning member traverses the circuit board in a movable relationship. A perforation is used to rotate the perforation, thereby allowing the board to be quickly placed on the housing. In this way, the user does not need to fix the circuit board by a plurality of sets of bolts, so that the circuit board can be assembled to the housing in a boltless manner, and the user can load and unload the circuit board more quickly and labor-savingly, thereby greatly improving the convenience of operation.

As such, the circuit board 200 can be placed on the housing 101.
The "4th" to "7A" diagrams are schematic exploded perspective views showing the circuit board of the second embodiment of the present invention mounted on the casing. When the circuit board 200 is mounted on the housing 101, the neck 112 of the binding post 110 on the housing 101 is received in the wide section 212 of the coupling hole 210. Next, as shown in FIG. 4, the circuit board 200 is displaced in a bonding direction with respect to the housing 101 such that the neck portion 112 of the bonding post 110 is embedded in the narrow section 214 of the coupling hole 210, and the two are coupled to each other. And the circuit board 200 is clamped on the casing 101. Subsequently, the holding portion 304c of the cylinder 304a is pressed downward as shown in "Fig. 5A".
