With rapid development of the Internet and cloud computing, a requirement for a communication device, which serves as a major hardware implementation scheme in terms of engineering, is also rapidly growing. As a major form of a network communication device, a cabinet-level communication device has various advantages over a rack-mounted communication device, a tower-mounted communication device, a blade communication device, and the like.
A backplane is an indispensable component of the cabinet-level communication device. A front board and a rear board of the cabinet-level communication device are effectively connected by the backplane. Generally, the backplane is arranged in the innermost of the cabinet-level communication device.
In a process of implementing the present invention, the inventor finds the following problem: in the prior art, the backplane is directly fixed on a rack of the cabinet-level communication device, and multiple screws used to fix and connect the backplane to the cabinet-level communication device are arranged on the backplane, thereby making it more difficult to assemble or disassemble the backplane; and when the cabinet-level communication device is faulty, generally the cabinet-level communication device has to be sent to a manufacturer to get disassembled and repaired by a professional technician, and generally cannot be changed or maintained by a user, thereby making it more difficult for the user to maintain the cabinet-level communication device, increasing a cost of using the cabinet-level communication device, and degrading use experience of the user.

Signs of the accompanying drawings are described as follows:
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
This embodiment of the present invention provides a backplane 1. The backplane 1 applies to a cabinet-level communication device. As shown in
The rear board is connected to the front board in an orthogonal connection manner through the backplane. The connection may be a physical connection or an electrical connection, and cabling is arranged inside the backplane 1, so that functions such as data exchange and signal transfer can be implemented between the rear board and the front board.
As shown in
In the technical solutions of the present invention, as shown in
In addition, the backplane 1 is fixed and arranged in a detachable manner in advance on the rear board 22 or the front board 21, and then, can be plugged or unplugged along with the rear board 22 that fixes the backplane 1 or the front board 2 that fixes the backplane 1, instead of being installed on a shelf in the prior art, thereby simplifying installation steps of the backplane 1.
Generally, when the front board 21 and the rear board 22 of the cabinet-level communication device 2 are working, plenty of heat is radiated. Therefore, in the prior art, generally, at least one cooling hole 13 of a varied size is arranged on the backplane 1, so that the heat can be rapidly dissipated to another place. Arranging the cooling hole 13, however, reduces the overall mechanical strength of the backplane 1 and causes the backplane 1 to be easily damaged, thereby affecting a service life of the backplane 1.
In the technical solutions of the present invention, the backplane 1 has a stripe structure and its size, especially a longitudinal size, is relatively small as compared with a backplane 2 in the prior art. As shown in
During installation, as shown in
Similarly, as shown in

This embodiment of the present invention provides a backplane 1. The backplane 1 applies to a cabinet-level communication device. As shown in
In this embodiment and the following embodiments, the base plate may be considered as a plate in a general sense and its material is not limited. For example, the base plate may be a printed circuit board (PCB) board or boards of other types (such as metal, wood, and compound material). The base plate may be considered as a hexahedron (because each board has a certain thickness), and the first face and the second face of the base plate are two flat surfaces having an obviously largest area among faces of the base plate. In addition, it should be noted that the first face and the second face are not necessarily on a physical media surface. In practice, the base plate may have some holes that thread through the first face and the second face, and the two surfaces having the largest area and the holes may still be considered as the first face and the second face.
The first connector and the second connector may be arranged as two independent connectors on the first face and the second face, respectively. Alternatively, the first connector and the second connector are made into an entire component, a mounting hole is opened on the base plate, and the entire component is placed in the mounting hole, so that the first connector and the second connector are located on the first face and the second face, respectively. A specific arranging method is a technology commonly known to a person of ordinary skill in the art, and no further details are provided herein.
In this embodiment, the rear board 22 is connected to the front board 21 in an orthogonal connection manner through the backplane 1. The connection may be a physical connection or an electrical connection, and cabling is arranged inside the backplane 1, so that functions such as data exchange and signal transfer can be implemented between the rear board 22 and the front board 21.
As shown in
In the technical solutions of the present invention, as shown in
In addition, the backplane 1 is fixed and arranged in a detachable manner in advance on the rear board 22 or the front board 21, and then, can be plugged or unplugged along with the rear board 22 that fixes the backplane 1 or the front board 2 that fixes the backplane 1, instead of being installed on a shelf in the prior art, thereby simplifying installation steps of the backplane 1.
During installation, as shown in
Similarly, as shown in
Specifically, as shown in
Generally, when the front board 21 and the rear board 22 of the cabinet-level communication device 2 are working, plenty of heat is radiated. Therefore, in the prior art, generally, at least one cooling hole 13 of a varied size is arranged on the backplane 1, so that the heat can be rapidly dissipated to another place. Arranging the cooling hole 13, however, reduces the overall mechanical strength of the backplane 1 and causes the backplane 1 to be easily damaged, thereby affecting a service life of the backplane 1.
In the technical solutions of the present invention, the backplane 1 has a stripe structure and its size, especially a longitudinal size, is relatively small as compared with a backplane 2 in the prior art. As shown in
Generally, the first connector 11 and the second connector 12 are connectors independent of each other and separated from each other, and are connected through the cabling in the backplane 1 after being arranged on the backplane 1. However, the first connector 11 and the second connector 12 may also be integrated. As shown in
It should be noted that a face on which the first connector 11 is arranged on the backplane 1 is called the first face, and a face on which the second connector 12 is arranged is called the second face, as mentioned previously. When the first connector 11 and the second connector 12 are integrated, a hollow hole for matching the hole of the first connector 11 and the second connector 12 needs to be added at a corresponding position of the backplane 1, so as to install the first connector 11 and the second connector 12.
As shown in
Generally, a matching relationship between the front board 21 or the rear board 22 and the cabinet-level communication device 2 is similar to a matching relationship between a drawer and a cabinet. That is, a slide rail is arranged on the cabinet-level communication device 2 to enable the front board 21 or the rear board 22 to be placed into the cabinet-level communication device 2, and a corresponding sliding wheel is arranged on the front board 21 and the rear board 22 as a device to match the slide rail, so that the front board 21 and the rear board 22 are quite conveniently installed. In the technical solutions of the present invention, because the backplane 1 is fixed and arranged in advance on the front board 21 or the rear board 22, the backplane 1 and the front board 21 or the rear board 22 is integrated. Then, the installation of the backplane 1 can be implemented after the backplane 1 and the front board 21 or the rear board 22 are placed together into the cabinet-level communication device 2, unlike the prior art in which the backplane 1 needs to be fixed on the cabinet-level communication device 2 first, thereby greatly reducing difficulty in installing the backplane 1.
During detachment, first, the front board 21 or the rear board 22 arranged with the backplane 1 needs to be taken out of the cabinet-level communication device 2, and then, the backplane 1 arranged on the front board 21 or the rear board 22 is detached, so that detachment of the backplane 1 can be implemented, unlike the prior art in which a shelf of the cabinet-level communication device 2 needs to be detached before the backplane 1 is detached, thereby reducing difficulty in detaching the backplane 1.
In sum, because a backplane 1 is installed and detached quite easily without requiring a professional person, a user can install and detach the backplane 1 on his or her own, thereby reducing difficulty in maintaining a cabinet-level communication device 2 arranged with the backplane 1 and reducing a maintenance cost and improving use experience of the user.
An embodiment of the present invention provides a cabinet-level communication device 2. As shown in
The rear board is connected to the front board in an orthogonal connection manner through the backplane. The connection may be a physical connection or an electrical connection, and cabling is arranged inside the backplane 1, so that functions such as data exchange and signal transfer can be implemented between the rear board and the front board.
As shown in
In the technical solutions of the present invention, as shown in
Specifically, connection relationships between the backplane 1, the front board 21, and the rear board 22 are as follows:
As shown in
Generally, a position of the first connector 21 of the backplane 1 may be arranged correspondingly according to distribution of the front board 22. For example, as shown in
Similarly, a position of the second connector 22 of the backplane 1 may be arranged correspondingly according to distribution of the rear board 22.
In addition, the backplane 1 is fixed and arranged in a detachable manner in advance on the rear board 22 or the front board 21, and then, can be plugged or unplugged along with the rear board 22 that fixes the backplane 1 or the front board 2 that fixes the backplane 1, instead of being installed on a shelf in the prior art, thereby simplifying installation steps of the backplane 1.

It should be noted that a face on which the first connector 11 is arranged on the backplane 1 is called the first face, and a face on which the second connector 12 is arranged is called the second face, as mentioned previously. When the first connector 11 and the second connector 12 are integrated, a hollow hole for matching the hole of the first connector 11 and the second connector 12 needs to be added at a corresponding position of the backplane 1, so as to install the first connector 11 and the second connector 12. In this case, a person of ordinary skill in the art may understand that the first face actually includes an entity face and a virtual face; and specifically, the entity face is a remaining flat part of the first face apart from the hole, the virtual face is a flat surface corresponding to the part of the hole, an area of the first face keeps unchanged, and similarly, the second face is like this.
As shown in
Generally, a matching relationship between the front board 21 or the rear board 22 and the cabinet-level communication device 2 is similar to a matching relationship between a drawer and a cabinet. That is, a slide rail is arranged on the cabinet-level communication device 2 to enable the front board 21 or the rear board 22 to be placed into the cabinet-level communication device 2, and a corresponding sliding wheel is arranged on the front board 21 and the rear board 22 as a device to match the slide rail, so that the front board 21 and the rear board 22 are quite conveniently installed.

As shown in
The metal support 3 may be arranged between the backplane 1 and the front board 21 or the rear board 22, so that the backplane 1 is more firmly fixed with the front board 21 or the rear board 22 and the backplane 1 is not easily damaged when being fixed on the front board 21 or the rear board 22.
As shown in
As shown in
On the contrary, during detachment of the backplane 1, first, the front board 21 or the rear board 22 arranged with the backplane 1 is taken out of the cabinet-level communication device 2; then, the backplane 1 and the metal support 3 are detached together from the front board 21 or the rear board 22; and finally, the backplane 1 is separated from the metal support 3.
Generally, as shown in
In the technical solutions of this embodiment, a cabinet-level communication device is provided. The cabinet-level communication device includes a backplane. The backplane has a stripe structure and has a small size. No cooling hole needs to be arranged on the backplane, and heat dissipation can be implemented simply through the space between backplanes.
