Description

a chassis

technical field

The utility model relates to multimedia communication technology, in particular to a cabinet.

Background technique

The current case generally includes: a case body, a main board disposed at the bottom of the case body, a plurality of service boards disposed on the main board through slots, and a power supply disposed on the bottom of the case body to supply power to power-consuming devices on the main board. In addition, if the heat generated by the power-consuming equipment is too large and affects the performance and stable operation of the equipment, it is also necessary to install a fan on the main board. Among them, the direction of the interface on the main board is the same as that of the interface on the service board, but the power supply is directly installed on the base and the input terminal is drawn out from the rear panel of the chassis.

Although the above-mentioned layout form of the existing chassis can meet certain requirements, it has the following disadvantages:

The number of single boards that can be installed in a certain space is small, and the corresponding business volume is small. If there is a demand for capacity expansion, it is difficult to solve;

The borrowability of the chassis is poor, and devices that use different connectors and different power supplies need to be redeveloped.

Utility model content

The utility model provides a case to solve the problem that the existing box-type case has a small number of single boards that can be installed in a certain space and is difficult to meet the expansion requirement.

The technical scheme provided by the utility model is as follows:

A kind of case, comprises case front panel, back panel, the power supply box that is arranged in the case, fan, also includes the backplane support that is arranged on the inner side of front panel, is provided with mainboard installation slideway on the backplane support, on described backplane A veneer support frame is provided between the bracket and the rear panel, and a plurality of slideways for inserting veneers are arranged in layers in the support frame.

The utility model has the following advantages: the main board and the interface board that do not need to be plugged in and out at any time in the multimedia equipment are placed in the backplane bracket set by the chassis, which can save the slot for installing the business single board, increase the capacity, and enrich the The electrical connection between the main board and the business single board is connected with the backplane installed on the backplane bracket. In the overall layout, modularization can be realized, and multiple devices can share one chassis, and the interface capacity is large. , can deploy more service boards and output more services in the smallest possible space, easy and convenient to expand capacity; at the same time, it is beautiful in appearance and compact in structure, and can be widely used in assembling multimedia products such as digital video.

Detailed ways

With reference to Fig. 1, Fig. 2, provide a kind of chassis that is used for assembling multimedia video equipment, be provided with the backplane bracket 4 that is used to install main board in the inner side of the front panel 1 of chassis, be provided with backplane on one side of backplane bracket 4 5. A veneer support frame 6 is provided between the back panel 5 and the rear panel 10, and a plurality of slideways for inserting business veneers are arranged in layers in the support frame 6. On both sides of the back panel 5, There are a plurality of connectors, and the business single board arranged in the multimedia case and the main board are plugged into the connectors arranged on both sides of the backboard 5 to form an electrical connection. One end of the main board 3 is provided with a handle bar 2 .

Referring to Fig. 2 and Fig. 3, the backplane 5 is arranged on one side of the backplane support 4, and slideways 401 and 402 for installing the main board 3 and the interface board 16 are provided on the backplane support 4. After the backplane support 4 is assembled, It can be put into the chassis as a whole, so that the installation accuracy of the interface board 16 , the main control board 3 and the backplane 5 is guaranteed firstly.

Referring to Fig. 2 and Fig. 4, a plurality of slideways 601 for inserting service veneers 9 are arranged in layers in the support frame 6. The track 601 is inserted into the 2mm connector provided on the other side of the backplane 5, and then locked on the slide track with captive screws.

Referring to Fig. 5, in addition, considering the requirement of AC and DC power input of the equipment and the change of the external interface of different types of products, a power supply rear panel can be designed at one end of the chassis rear panel 10, and an interface 13 is provided on the rear panel of the power supply. Input socket 14 and power switch 15.

When using the case to assemble multimedia equipment, the support frame 6 can be directly fixed on the case base 7 with rivets, which is convenient for accurate positioning. The process of inter-plugging the business boards is as follows: first, fasten the backplane 5 to the backplane support 4 with screws, and then fix the interface board and the main control board 3 on the corresponding handle bar 2, which can be installed on the backplane Insert the chute on the bracket 4 into the 2mm connector on the backplane, and then tighten the captive screws on the handle bar 2 into the rivet nuts on the backplane bracket 4. After the backplane bracket 4 is assembled, it can be put into the chassis as a whole, so that the installation accuracy of the interface board, the main control board 3 and the backplane 5 is firstly guaranteed. After the same service veneer 9 is installed with the dummy handle 8, insert it into the 2mm connector on the other side of the backplane 5 through the chute on the slideway of the support frame, and then lock it on the slideway with captive screws.
