Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a fiber optic switch chassis. Background Art

[0002] A fiber optic switch is a high-speed network transmission relay device, also known as a fiber channel switch or SAN switch. Compared to ordinary switches, it uses fiber optic cables as the transmission medium. Fiber optic transmission has the advantages of high speed and strong anti-interference ability. However, most existing fiber optic switch chassis are rectangular shells. Due to the lack of a fixed structure for the interface data line body, the connection load between the data line and the chassis interface is large. When the data line is pulled by external force, the conductive connector in the interface is easily deformed, affecting the stability of signal transmission. On the other hand, when multiple fiber optic switches are stacked together, they are prone to phase slippage, affecting the installation stability of the fiber optic switches. To this end, we propose a fiber optic switch chassis that can reduce the load at the data line connection and improve the stacking stability of the fiber optic switch. Utility Model Content

A convex cavity is integrally formed at the end of the box body, and the convex cavity is connected to the wiring board through an adaptor card. When multiple boxes are accumulated, the adjacent boxes can be clamped together, thereby preventing the boxes with higher accumulated positions from slipping, thereby improving the stability of the fiber optic switch. An arc channel is provided on the side of the convex cavity facing the interface component, and the arc channel can adapt to the data line at the lower accumulated position, thereby providing an accommodation space for the wiring layout of the data line, which is beneficial to improving the neatness of the accumulated placement between the boxes and facilitating the arrangement of the data lines. A ventilation structure is installed on the side of the box body, and the ventilation structure includes ventilation holes and fans provided on the connecting surface between the convex cavity and the box body. The ventilation structure can ventilate and dissipate heat inside the box. To prevent the internal temperature of the switch from being too high, a wiring board is welded on the top of the box. The wiring board can be adapted and snapped into the depression on one side of the convex cavity. The top of the wiring board is provided with limit openings equal to the number of the interface components, which can ensure that each data cable has a reasonable routing channel, facilitating the arrangement of the data cables.

[0010] As a further solution of the utility model: the inner wall of the limit opening is glued with an anti-slip sheet, which is an elastic thin sheet made of rubber or silicone.

[0025] Preferably, Figure 1 As shown, the box body 1 is a hard aluminum alloy shell with an insulating layer coated on the surface. The box body 1 made of aluminum alloy is conducive to rapid heat conduction of the box body 1.

[0026] Preferably, Figure 1 As shown, the optical exchange interface 3 includes an optical access interface and an optical output interface. The optical exchange interface 3 is arranged linearly at equal intervals and has multiple optical exchange interfaces. The optical exchange interface 3 passes through the side of the box 1 and is fixed. The optical exchange interface 3 can connect the data line 13 through the connector 12 to exchange data between the optical fiber switch and the external device.

[0028] Preferably, Figure 1 As shown, a plurality of ventilation holes 4 are provided, and a fan 11 is installed through the side surface opposite to the surface where the ventilation holes 4 are located.

When the data line 13 is tightly snapped against the inner wall of the limiting opening 8, the stress at the connection between the connector 12 and the optical exchange interface 3 can be balanced, and at the same time, the data line 13 can be prevented from being accidentally pulled to affect the connection stability of the connector 12, thereby ensuring the stability of the signal exchange transmission of the optical fiber switch.
