Description

Board layout setting separable device

The utility model relates to a detachable device for circuit board layout setting, which facilitates the separation and combination of the circuit board adjustment component and the circuit board.

Usually there must be a variety of different layout settings on a multi-functional circuit board, each layout setting is adapted to a specific environmental requirement, and in order to change the layout settings of the circuit board in different surrounding environments, in Adjustments to adjust layout settings are provided in many places on the board.

As shown in Figure 1, take computer motherboard 1 as an example, in order to provide users with convenience and money for upgrading computers or replacing parts in the future, computer motherboard 1 usually does not have only one layout design. Certainly, because there is only one layout setting, when replacing or upgrading, the computer motherboard 1 must be completely replaced, wasting time and money. Therefore, the existing computer motherboard 1 must have multiple different layout settings, and the computer motherboard 1 is provided with an adjustment device 11 for adjusting the layout settings. line "Jumper" terminal) and more than one jumper connector 13, one end of these terminals 12 penetrates into the computer motherboard 1 and is electrically connected to it, and the other end extends vertically from the computer motherboard 1 to make adjacent The two terminals 12 are parallel to each other, the jumper connector 13 has an insulating shell 130, and the insulating shell 130 is provided with a conductor 131 and two through holes 133, the conductor 131 is connected with the two through holes 133, and the two through holes 133 can be correspondingly placed on the two adjacent terminals 12, and when the jumper connector 13 is inserted into the adjacent two terminals 12, the two adjacent terminals 12 are electrically connected via the conductor 131 inside the jumper connector 13, by selecting different terminals 12 electrical connections, so that the computer motherboard 1 is applicable to different components, as the layout of the computer motherboard 1 is set to "A" state, then the computer motherboard 1 is applicable to the central processing unit (CPU) of the "A" class. , not shown in the figure), and when the layout of the computer motherboard 1 is set to the state of "B", then the computer motherboard 1 is suitable for the central processing unit (CPU, not shown in the figure) of the "B" class, and other such as interface Card settings, temporary memory (RAM) settings, etc.

Although the existing adjustment device 11 can change the layout settings on the computer main board 1, this adjustment device 11 is fixedly arranged on the computer main board 1. When the user replaces the internal components of the computer, he must Feel extremely inconvenient, because computer main board 1 is generally located in the inside of computer case (not shown in the figure), is subjected to the interference of many computer case internal structures, hard disk drive, interface card, flat cable, power cord etc., therefore, must break through There are many obstacles, carefully looking for the adjustment device 11 in the dark and unknown computer casing, and then replacing the sleeve terminal 12 of the jumper connector 13 with clips or by hand, and the jumper connector 13 often falls off. into the computer casing, and the dropped jumper connector 13 is likely to be stuck by other equipment, or even cause a short circuit in other equipment, thus causing greater trouble in use.

In addition, there are also some worse designs to fix the adjusting device 11 on the computer motherboard 1 in a scattered manner, rather than concentrating on a relatively convenient place. This design not only has the aforementioned disadvantages, but also has greater The biggest inconvenience is that when adjusting the layout setting, the user must spend more time and effort to find each adjustment device 11 that needs to be adjusted. Like this, various bad designs all can cause great inconvenience to the user.

Fig. 3 is a schematic side view of the above embodiment.

FIG. 4 is a three-dimensional schematic diagram of a circuit sub-board according to another embodiment of the present invention.

As shown in Figure 2, the embodiment of the present utility model takes the circuit board in the computer mainframe as an example, that is, the main board 3. Taking the main board 3 as an example is mainly because the current main board 3 must be able to adapt to a variety of different frequencies. The central processing unit (not shown) or other different interface cards must be provided with multiple different layout settings on the motherboard 3 to meet the needs of computer upgrades or changes.

In this embodiment, the circuits for controlling the layout setting on the main board 3 must be arranged in an appropriate place first, and then a first connector 4 is provided here, and the first connector 4 has several first terminals. 41 and a first joint portion 43, in this embodiment, the first joint portion 43 is a slot-shaped socket, and one end of these first terminals 41 is respectively connected with the circuit board 3 for controlling the layout setting. A circuit (not shown) is electrically connected, and the other end extends to the first joint portion 43 .
