Description

A 1U communication case with a fan box

technical field

The utility model relates to a 1U communication case with a fan plug-in box, specifically a pluggable communication case with a fan plug-in box structure and conforming to 1U specification communication equipment products, especially suitable for non-terminal properties such as optical transmission communication equipment products.

Background technique

In the communication chassis of 1U (44mm height, 480mm width) communication equipment products, there is a problem of how to dissipate heat. At present, general products adopt fanless structure or fixed fan structure.

The fanless structure means that there is no fan in the chassis, and the heat inside the chassis is dissipated into the air by the casing of the chassis.

The fixed fan structure is to install the fan inside the case and fix it with the case by means such as screws.

The fanless structure has relatively high heat dissipation requirements for the chassis shell.

The fixed fan structure has the problem that it is relatively difficult to maintain the fan. When the fan fails, it is first necessary to open the chassis shell, and use tools to release the fixed connection between the fan and the chassis body, and then replace the fan.

The inner side of the chassis body is provided with guide rails, which are used for fan sub-box installation and can be plugged freely with the chassis body, and the bottom of the chassis body is fixed with a back plate.

The backplane is a PCB single board, and the fan sub-box and various functional single boards are inserted into the inside of the chassis body along the inner guide rails of the chassis body, and are connected with the backplane board. The fan sub-box, the back panel and other functional single boards are fixed in the case body. The back panel and other functional boards are fixed on the bottom of the chassis body with screws, and connected with the plugs of the functional boards and the sockets of the rear board to realize the connection of power supply and digital signals between the fan subracks and various functional boards. send.

The fan sub-box and the chassis body can be plugged freely. Multiple fans are installed in the fan sub-box. The fans have the functions of speed control and speed output. The front panel of the fan sub-box has a handle.

The fan sub-box can be located at the leftmost part of the case body, and can be inserted and removed from the case body. Three fans and one PCB board are installed in the fan subbox, and are fixed in the fan subbox with screws. The fans have the function of speed control. The plug on the power supply and speed control line of the fan is connected to the socket on the PCB board in the fan sub-box, and the PCB board in the fan sub-box passes through the plug installed on the PCB board and the socket installed in the chassis body. Socket connections on the rear panel.

The power supply and speed control signal of the fan on the rear panel are transmitted to the plug installed on the PCB board in the fan subbox through the socket installed on the rear panel, and then the PCB is transmitted through the circuit on the PCB board in the fan subbox The socket on the single board is then transmitted to the fan itself through the fan power supply line and the fan speed control line plugged into the socket, so as to drive the fan to work. The fan works to draw air to the chassis. The air enters from the right shell of the chassis and is sent out from the left shell of the chassis to cool the inside of the chassis.

Figure 2 shows the specific structure of a 1U chassis with a pluggable fan box. As shown in Figure 2, the 1U chassis is divided into several slots, and the leftmost slot is installed with a pluggable The fan subrack (2 in Figure 2), and other functional boards (8 in Figure 2) are installed in the remaining slots.

A backplane (5 in Fig. 2 ) is installed inside the case, and a socket (4 in Fig. 2 ) is arranged on the backplane. The functional single boards on each slot are inserted into the chassis through the guide rails (3 in Figure 2), and are connected to the sockets on the rear panel (4 in Figure 2) through the plugs on the functional single boards to realize the communication of electrical signals. connect.

Captive screws (6 in Figure 2) are installed on the panel of the functional single board. When the functional single board is inserted into the chassis through the guide rail (3 in Figure 2), and inserted into the socket on the back panel , use two captive screws (6 in Figure 2) to fix.

The specific structure of the fan sub-box described in the utility model is shown in Figure 3. As shown in Figure 3, the fan sub-box is mainly composed of a sub-box (8 in Fig. 3), a fan (3 in Fig. 3), a fan plug The PCB single board (9 in Fig. 3) in the box is composed of three parts.

The plug-in box body is a metal structure, and there is a handle (1 in Figure 3) on the plug-in box body, which is convenient for inserting and pulling out the fan sub-box. There are fixers (2 and 11 in Fig. 3) on the sub-box body, and when the fan sub-box is inserted into the chassis, the fan sub-box body and the chassis body are fixed by the fixer.

Three fans (3 etc. in Fig. 3) are installed in the fan sub-box, and the fans are fixed in the fan sub-box by screws (12 in Fig. 3). The fan has a speed control function. One end of the speed control line and power supply line of each fan is drawn from the fan body, and the other end is a three-core hole plug structure.

A PCB board (9 in Figure 3) is installed in the fan subbox, and is fixed in the fan subbox with screws. There are three three-core PCB single-board sockets (5 in FIG. 3 ) and one PCB single-board plug (6 in FIG. 3 ) on the PCB single board. The corresponding signal lines and power lines of the two are connected through circuit traces on the PCB single board. The respective three-pin hole plugs on the three fans are connected to the three three-pin sockets on the PCB board installed in the fan subrack.

In normal working mode, the fan sub-box (2 in Fig. 2) is inserted into the case along the inner guide rail (3 in Fig. 2), and the plug on the PCB board in the fan sub-box (6 in Fig. 3) It is connected to the corresponding socket (7 in Figure 2, 7 in Figure 3) on the rear panel in the chassis, and other functional single boards are also inserted into the chassis along the guide rail (3 in Figure 2) and connected by captive screws ( 6) in Fig. 2) is fixed on the chassis body (1 among Fig. 2).

The power signal and speed control signal sent from other functional single boards (8 in Figure 2) go through the socket on the backplane (4 in Figure 2), and go through the circuit on the backplane (5 in Figure 2). The wire is transmitted to the socket on the rear panel (7 in Figure 2, 7 in Figure 3), and then transmitted to the plug on the PCB single board in the fan box (6 in Figure 3). After the power signal and speed control signal reach the PCB board in the fan subrack, they are transmitted to the sockets on the three three-core PCB boards through the circuit traces on the PCB board (9 in Figure 3) in the fan subbox (5 among Fig. 3), transmit to fan itself through three three-core hole type plugs connected with it at last, thereby drive fan to rotate according to the speed specified by the speed control signal.

When the fan sub-box (2 in Fig. 2) is pulled out along the guide rail (3 in Fig. 2) inside the chassis, the plug on the PCB board in the fan sub-box (6 in Fig. 3) and the back of the chassis The sockets on the board (7 in Fig. 2, 7 in Fig. 3) are separated, so that the fan power signal and speed control signal cannot reach the fan, and the fan stops rotating.
