The present disclosure generally relates to the field of surge protectors, and more particularly to the field of Ethernet surge protectors.
Surge protection is the process of protecting electronic systems or equipment from voltages and currents which are outside their safe operating limits. Surge voltages and surge currents can be generated by short circuits, lightning or faults from a power system, and they may enter the electronic system along inter-equipment wiring. As in the case of a lightning strike, for example, the surges may be galvanically coupled into an electronic system through an inadvertent connection of the power system to wiring. In another example, the surges may be capacitively coupled into an electronic system that is in the vicinity of a high voltage power line. In another example, the surges may be inductively coupled into the electronic system if electronic wiring is run in parallel with a power circuit.
Surge protection devices may be used for protecting electronic systems or equipment from surges. Specifically, an Ethernet surge protection device may protect Ethernet interface devices that are used in a computer system and/or a server system. Conventional Ethernet surge protection devices are not mounted to a wall of a building because they lack mounting components for fitting into a standard bulkhead panel. As such, conventional Ethernet surge protection devices are installed adjacent to the Ethernet interface devices, which are generally located inside a building.
Existing Ethernet surge protection devices may require professional installation given that the surge protection device must be attached to a proper earth ground. Under this circumstance, up to 25 feet of copper wire may need to be run from the surge protector to a ground point. Additional equipment may be required to attach the copper wire to the ground point. Accordingly, there is a need to allow easy installation of a surge protection device without having to connect the surge protection device to a copper wire and connecting that copper wire to a proper earth ground.
A surge protector is configured to protect Ethernet equipment from an electrical surge. The surge protector includes a housing portion configured to have a first housing portion and a second housing portion, a printed circuit board structurally configured to be disposed within the housing portion and configured to be electrically coupled with an input Ethernet cable and with an output Ethernet cable, and a ground plug portion structurally configured to include a panel portion, a dummy portion, and a ground portion, wherein the second housing portion is structurally configured to include an electrical coupling portion, wherein the ground portion is structurally configured to includes a proximate end extending beyond a first side of the panel portion and a distal end extending beyond the a second side of the panel portion, wherein the ground portion is structurally configured to extend from the second side of the panel portion, wherein the proximate end of the ground portion is structurally configured to be electrically coupled with the printed circuit board via the electrical coupling portion, and the distal end of the ground portion is structurally configured to be electrically coupled with a ground of an electrical wall outlet, wherein the second housing portion is configured to define a port on a rear exterior side of the housing portion such that the port is structurally configured to receive the panel portion of the ground plug portion, wherein the electrical coupling portion of the second housing portion includes a first end structurally configured to extend beyond an interior side of the second housing portion and a second end, wherein the second end of the electrical coupling portion is a ring such that at least a portion of the ring is structurally configured to extend beyond the rear exterior side of the second housing portion, wherein the ground plug portion is structurally configured to mechanically couple the housing portion to an electrical wall outlet, and wherein the ground portion and the electrical coupling portion of the housing portion are structurally configured to electrically couple the printed circuit board to a ground of an electrical wall outlet via the ground plug portion when the housing portion is coupled to the electrical wall outlet such that an electrical surge on the input Ethernet cable is directed to the ground of the electrical wall outlet so as to protect equipment that is electrically connected with the output Ethernet cable from the electrical surge.
A surge protector is configured to protect Ethernet equipment from an electrical surge.

The figures are not necessarily to scale. However, it is to be understood that the disclosed embodiments are merely exemplary of the present disclosure that may be embodied in various and alternative forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for any aspect of the present disclosure and/or as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
It is also to be understood that this present disclosure is not limited to the specific embodiments and methods described below, as specific components and/or conditions may, of course, vary. Furthermore, the terminology used herein is used only for the purpose of describing particular embodiments of the present disclosure and is not intended to be limiting in any way.
It must also be noted that, as used in the specification and the appended claims, the singular form “a,” “an,” and “the” comprise plural referents unless the context clearly indicates otherwise. For example, reference to a component in the singular is intended to comprise a plurality of components.
The subject of damage to Ethernet ports due to surges in current has received increased attention in recent years. For reasons that are not fully understood, more manufacturers are experiencing field failures caused by visible surge damage to Ethernet ports. Other suspected surge failures do not show visible damage, but the timing of the failures correlates with local thunderstorm activity.
The IEEE 802.3 standard defines a method for delivering DC power over an Ethernet cable. Current versions of power over ethernet (PoE) use two of the four pairs in the cable to deliver DC current to the far end. One pair serves as the source, while the other pair serves as the return. The standard defines two choices for delivering the DC power. Mode A uses pairs 1 and 2, while Mode B uses pairs 3 and 4.
The DC voltage is typically in the range of 50 volts, with the current limited to approximately 270 mA. This provides the ability to deliver up to 13 watts of power to a device connected to the far end of the Ethernet cable. For remote devices such as telephones and security cameras, the main benefit of PoE is that it eliminates the need for a separate power supply to power the remote device.
The first and second Ethernet enabled computers 105 and 107 may be connected to one or more computer networks via one or more Ethernet cables. For example, the first Ethernet enabled computer 105 may be connected to a first protected Ethernet cable 142, the internally mounted ESP device 122, and a first unprotected Ethernet cable 132.
The first and second unprotected Ethernet cables 132 and 134 may be disposed outside the building 101. The first and second unprotected Ethernet cables 132 and 134 may each conduct an Ethernet signal. The voltage and current of the Ethernet signal may be affected by several external conditions, such as lightning, power line interference, and/or earth potential rise. Generally, these external conditions may introduce a surge component to the Ethernet signal. The surge component may include a surge voltage and/or a surge current.
Excessive surge voltage and/or surge current may cause damage to the Ethernet interface devices (not shown) of the first Ethernet enabled computer 105 and the second Ethernet enabled computer 107. To protect the Ethernet interface devices from surge voltage and/or surge current, an ESP device (e.g., the internally mounted ESP devices 122) may be used for suppressing and/or filtering out the surge component of the Ethernet signal. The ESP device may output the filtered or surge suppressed Ethernet signals to one or more protected Ethernet cables, such as the first protected Ethernet cable 142 and the second protected Ethernet cable 144. Consequently, the filtered or surge suppressed Ethernet signals may be delivered to the first Ethernet enabled computer 105 and the second Ethernet enabled computer 107.
The ESP device may be mounted inside the building 101. More preferably, the ESP device may be mounted to a wall 104 of the building 101 and in some embodiments may use a dedicated mounting fixture 110. The mounting fixture 110 may include one or more panels for holding the ESP devices. The mounting fixture 110 may have a zigzag shape as shown in

The ground plug 16 may be rotated relative to the housing 12 so that the ground plug 16 is structurally configured to be removable from the housing 12 and from the Ethernet surge protection device 10. While the figures illustrate a ground plug 16 configured to plug into a standard 120V three-prong wall outlet, embodiments disclosed herein may function with other wall outlets, such as a 220V wall outlet. A different ground plug may replace the ground plug 16 in the housing of the surge protection device, with the different ground plug having a configuration to fit into a corresponding different wall outlet. The different ground plug will have prongs with a placing, shape and size of the prongs configured to fit into the corresponding wall outlet.
For example, when using with a 220V wall outlet, the placing, size and shape of the prongs on the ground plug will correspond to the 220V outlet so that the ground plug can be plugged into the 220V outlet while connecting the ground prong to the ground of the 220V outlet. The different ground plug still has the tabs 70 and recesses 72 so that it may easily be inserted into the housing of the surge protection device. In this manner, the surge protection device is configured to function with various different types of wall outlets.
Noting that the proximate end 44 of the ground prong 42 is a protrusion that extends beyond the first side 46 of the panel 34 (see
