Description

200153 socket manually is time consuming work wherein each conductor within the cable shall be placed and secured in the right position.

[0005] As previously stated, one of the most common standards to use are RJ- 45 connectors together with CAT-5 or CAT-6 cables. However, many different standards exists and out of those standardized connectors, such as registered jacks (RJ) RJ-45, RJ-61, RJ- 25, RJ-14, and similar, most comprises latches that are adapted to secure the plug portion of the connector to the socket portion of the connector. The latches are very well adapted for securing a plug in a socket but as appreciated by the person skilled in the art they easily break.

[0006] There are multiple problems associated with the prior art solutions and the installation process thereof. For example, upon conducting installations it is rather uncommon to only install one cable and many devices requires more than one cable for their communication. ln some cases, multiple devices shall be installed at the same location increasing the need for multiple cables. One problem with the prior art solutions is that the cables can easily be connected wrongly creating a situation wherein the cables for example are swapped between multiple devices. This is in prior art solved in a non-satisfactory way by for example labels that states an identification number for each cable. Another problem is that the amounts of installation errors due to the connection of sockets to cables are extensive. Yet another problem is that when a device finally is installed they are normally arranged in a public environment. This has the effect that cables easily may become disconnected, for example during cleaning of the area or due to an act of sabotage.

Summary of invention

[0007] An object of the present invention is to provide a solution for easy and secure mounting of a device to a surface, such as a wall.

[0008] Another object of the present invention is to provide a solution minimizing the risk of connecting cables to the wrong device, or in the wrong port at the right device. 200153

[0009] Yet another object of the present invention is to improve security of network installations.

[0010] Another object of the present invention is to eliminate the need of replacing patch cables with damaged Iatches.

[0011] Thus, the invention relates to a back plate in a device mounting system for arranging a device to an installation back box. The back plate comprises means to attach said back plate to the installation back box and at least one aperture extending through said back plate. The aperture is adapted to receive a modular connector plug, preferably an RJ45 connector, and a latching tab thereof and the aperture is adapted to secure said modular connector plug within the aperture while securing said latching tab in a disengaged position.

[0012] lt is one advantage with the present solution that the latching tab arranged on a modular connector plug is secured in a disengaged position preventing it from locking a modular connector socket placed in electrical connection with the modular connector plug. This enables for a device, receiving said modular connector socket, to be connected and disconnected without the need to disengage the latch. This further provides multiple advantages over prior art solutions regarding utilizing mounting of a device. The back plate is part of a device mounting system adapted to arrange a device on for example a wall or cable tray and it is one advantage of the present solution that the modular connector socket is arranged on the back of the device creating a solution wherein the device can be arranged directly to the back plate.

[0013] Furthermore, through securing the latching tab in a disengaged position the latching tab is protected from interference of users connecting and disconnecting the device which has the advantage that the latching tabs don”t break as easily.

[0014] ln one embodiment of the back plate in a device mounting system is the aperture adapted to secure the modular connector plug in a position where the modular connector plug extends from said back plate in an outwards direction that 200153 4 enables one or more electric connecting surfaces of said modular connector plug to engage with an electric connecting surface of a corresponding modular connector plug.

[0015] lt is an advantage of the present solution that the modular connector plug extends from the back plate in an outwards direction in order to facilitate mounting of the device thereto. The device for use with any embodiment of the back plate in a device mounting system preferably comprises modular connector sockets arranged on the back face of said device. Said modular connector sockets are furthermore preferably adapted for enabling an electric connection engagement to the modular connector plugs extending from the back plate.

[0016] lt is another advantage of the present solution that the need for a separate patching cable is eliminated. This improves the security of installations both through concealing the modular connectors and thereby preventing an unauthorized user to plug in a non-authorized device on the network. This improves the vulnerability of the system. Furthermore, removing the patch cable decreases the risk that the device is unintentionally disconnected, or intentionally through an act of sabotage or disconnection.

[0017] ln one embodiment of the back plate in a device mounting system, the at least one aperture comprises a first notch arranged to secure the modular connector plug in a first longitudinal direction of the aperture and a second notch arranged to secure the modular connector plug in a second longitudinal direction of the aperture.

[0018] lt is an advantage of the back plate that the aperture is designed to secure the modular connector plug from movement in all directions.

[0019] According to one embodiment of the back plate in a device mounting system are the means to attach the back plate to the installation back box at least two fastening tabs.

[0020] According to one embodiment of a device mounting system comprising a back plate, the device mounting system further comprises connection attachment 200153 means, a device, a cable, at least one modular connector plug, and an installation back box.

[0021] According to one embodiment of a device, such as a nurse call system panel, in a device mounting system, does the device comprise corresponding modular connector sockets adapted for electric connection to the modular connector plugs extending from the back plate.

[0022] The device can be any form of device, such as a router, access point, medical call system, or any other form of device. ln a preferred embodiment are the devices adapted for communication systems.

[0023] According to one aspect for securing at least one modular connector plug comprising a latching tab in a back plate arranged in a device mounting system, wherein the device mounting system is adapted for arranging a device to an installation back box, wherein the back plate comprises means to attach said back plate to the installation back box and at least one aperture extending through said back plate, are the following steps performed: -the modular connector plug attaches to a cable that through electric installation is located in the installation back box, -the modular connector plug, preferably an RJ45 connector, is entered into said aperture, -the aperture secures the modular connector plug within the aperture, and -the aperture secures said latching tab in a disengaged position.

[0024] According to one embodiment are the following steps further performed: -the aperture secures the modular connector plug in a position where the modular connector plug extends from said back plate in a outwards direction that enables one or more electric connect surfaces of said modular connector plug to mate with electric connect surface of a corresponding modular connector socket.

[0025] According to one embodiment, the aperture further comprises a first notch arranged to secure the modular connector in a first longitudinal direction of 200153 the aperture and a second notch arranged to secure the modular connector plug in a second Iongitudinal direction of the aperture.
