## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is related to Applicant's concurrently filed U.S. patent application Ser. No. 13/600,166, entitled a “Resource Manager, System and Method for Communicating Resource Management Information for Smart Energy and Media Resources” and filed on Aug. 30, 2012, the disclosure of which is expressly incorporated by references as though set forth fully herein.
TECHNICAL FIELD
The present invention relates generally to an improved terminal design for a wall mounted device, which allows the terminal to be mounted closer and more efficiently to the wall.
BACKGROUND OF THE INVENTION
Wall mounted electronic devices, such as thermostats, alarms and the like are well known. These wall mounted devices typically employ terminal blocks to allow the device to be electrically connected to wires located in the wall to which they are mounted. While these wall mounted devices are known to be manufactured in different sizes and shapes, they generally have an opening in the back that allows the wires from the wall to be connected to the terminal block in the housing by passing through the opening. The openings in the back of these wall mounted devices are generally elongated with a rectangular or square shape. Also, the terminal blocks utilized in these wall mounted devices are typically elongated and oriented in a linear arrangement such that they lie parallel to the sides of the opening in the back of the housing.
The configuration of the openings in the back of these wall mounted devices in combination with the terminal block located in the housing requires wires of different lengths to effectuate a connection with each of the terminals that make up the terminal block. For example, the wires that connect to the terminals on the ends of the terminal block must be longer than the wires that connect to the interior terminals on the terminal block. There thus is generally more wire in the housing or between the wall and the housing than is necessary, which can bunch up and prevent the back of the wall mounted device from being closely mounted to the wall. This can be undesirable and aesthetically unattractive.
Additionally, the connection of the wires to the terminals of the terminal block in most existing wall mounted designs requires a cumbersome and time consuming attachment process. Specifically, many existing terminal connections utilize a screw connector that requires loosening of a screw to allow a wire to be inserted into the terminal. Once the wire is in place, the screw must be tightened with a screw driver or the like to secure the wire firmly in the terminal.
It would therefore be desirable to provide a wall mounted device that overcomes these disadvantages.

FIGS. 1 through 3 illustrate an electronic device that can be mounted to a wall 10. In accordance with one aspect, the electronic device includes a housing 12. The housing 12 may be part of an electronic device that is one of or any combination of an energy management system, an energy management device, a network device, a personal computer, a consumer electronic device, a media device, a smart utility meter, an advanced metering infrastructure, a smart energy device, an energy display device, a home automation controller, an energy hub, a smart energy gateway, a set-top box, a digital media subscriber system, a cable modem, a broadband communication device, a fiber optic enabled communications device, a media gateway, a home media management system, a media server, a network server, a network storage device, a wireless speaker, a customer engagement platform, a customer engagement portal, a retail energy provider's server, a wholesale energy provider's server, a COOP energy provider's server, a retail business server, a commercial site server, an industrial site server, a multi-residential site server, a temporary lodging server, a hotel server, a motel server, a condominium server, a utility provider's server, which can include waste, water, power or combinations thereof, an energy substation, a news media server, a weather server, an advertisement server or service provider, a network radio server or service provider, a network media server or service provider, a music server or server provider, a search engine server or service provider, an information server or service provider, a wireless information network device, a vehicle charging station, a renewable energy production device, a renewable energy control device, an energy storage management system, a smart appliance, an HVAC system, a water pump, a heat pump, a hot water heater, a thermostat (TSTAT), an energy controller, an irrigation system, a lighting system, an alarm system, a smart power outlet, an energy detection device, a garage door opening system or device, a power management device, a power measurement unit (PMU), an air handler, a wireless air damper, a humidity control system, a heat and motion sensing device, a smart power outlet, a switch router, a wireless router, an automobile or transportation device, a network communication device, or any other suitable device or system, and can vary in size, shape, performance, functionality, and price.
In accordance with one aspect, the housing 12 includes a front surface 14, a rear surface 16, a top wall 18, a bottom wall 20, and a pair of opposing side walls 22, 24. The front surface 14 may include a terminal block 26 disposed thereon. According to one aspect, the terminal block 26 may be in communication with a printed circuit board 28 disposed therein. The terminal block 26 may have an arcuate shape, such as a u-shape or semi-circular shape. However, any other arrangements of the terminal block 26 could also be used. A terminal block 26 could also consist of multiple terminals that are individually attached and oriented within the housing 12. The terminal block 26 may include a plurality of individual terminals 30 each having an orifice 32. Each terminal 30 can allow for an individual electrical connection as will be understood by one of ordinary skill in the art and as described in more detail below.
In accordance with a further aspect, the housing 12 can include an opening 34 disposed therethrough that enables wires, such as HVAC wires, located in the wall 10 to pass through the opening 34 for communication with the terminal block 26. The opening 34 may be circular, oval, square, rectangular or a variety of other suitable shapes. In accordance with one aspect, the terminal block 26 is configured such that each terminal 30 is disposed equidistant from at least one point of the opening 34. For example, the opening 34 could be configured as a circle and the terminal block 26 could be oriented in a generally arcuate shape such that the orifice 32 of each of the terminals 30 is disposed equidistant from the center point 36 of the opening 34. This arrangement can help prevent bunching of excess wires as the same length of wire can be utilized to make a connection between the wall and each terminal. This can allow the housing 12 to be mounted close to the wall and provide a more orderly arrangement of wires. In accordance with this aspect, the terminal 30a can be disposed a distance (d1) from the center point 36, the terminal 30b can be disposed a distance (d2) from the center point 36, and the terminal 30c can be disposed a distance (d3) from the center point 36 where the distances (d1), (d2), and (d3) are the same. In accordance with this example, the shape of the opening generally matches the shape of the terminal block 26 such that the wires from the wall 10 that pass through the opening 34 can each have the same length and can be “fanned” out to make their respective connection with each of terminals 30. Other configurations of the opening 34 and the terminal block 26 could also be employed. For example, the opening 34 could be configured as a half circle and the terminal block 26 could be oriented in a generally arcuate shape such that each of the terminals is located equidistant from a midpoint of the linear side of the half circular shaped opening. Other combinations of opening shapes and terminal block shapes may be utilized that require less wire from the wall to be disposed within the interior of the housing 12 or minimizes excess wire and bunching thereof between the housing and the wall.
The housing 12 may serve as all or part of an electronic device. In accordance with one aspect, a cover plate 42 could be removably attached to the housing 12 to close off access to the interior of the housing, including the terminal block 26. In accordance with another aspect, the housing 12 can include a connector 40 to allow attachment of a front structure 44 at a front connector 46. Obviously, other suitable structures for effectuating a connection could be employed. By this connection, the front structure 44 when electrically connected to the housing 12 could form a single electronic device or alternatively, the housing 12 and the front structure 44 could form two separate devices that are attached. For example, the housing 12 could serve as a fully functional thermostat while the front structure may embody a multimedia device.
As shown, each of the terminals 30 can allow for an easy and quick connection of a wire thereto without the need for tools to effectuate a secure connection. According to one aspect, each of the terminals 30 may include a portion 48 that can be pushed inwardly to expose the orifice 32 such that a wire can be inserted therein to make the connection. When the portion 48 is released, a spring force urges the terminal toward a position closing off the orifice 32 such that a wire inserted therein is secured by the walls of the orifice as will be readily understood by one of ordinary skill in the art. It will also be understood that other suitable mechanism for quickly exposing the orifice may be employed.
As shown in the drawings, in accordance with one aspect, each of the terminals 30 has a top surface 50 that lies generally parallel to the rear surface 16 of the housing 12 and a front surface that has an angled portion 52. In one aspect, the orifice 32 of each terminal 30 is formed in the angled portion 52 to facilitate ease of insertion of the wire thereto.
The foregoing invention has been described in accordance with the relevant legal standards, thus the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and do come within the scope of the invention. Accordingly, the scope of legal protection afforded this invention can only be determined by studying the following claims.
