## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims the benefit of U.S. Provisional Patent Application No. 61/664,147 filed Jun. 25, 2012, the contents of which are incorporated herein by reference in their entirety.


TECHNICAL FIELD
The present invention relates to access control systems, and more particularly, but not exclusively, to the installation of a wall mounted access credential reader.
BACKGROUND
The current practice for installation of an access credential reader includes soldering a pigtail harness into the reader while leaving several bare wires exposed for connection to wiring in a structure. Typically, an installer attaches one of the bare wires to a corresponding wire from the structure, then hangs the reader from the wire while connecting the remainder of the wires to the corresponding wires from the structure. This approach is time consuming, cumbersome, and can result in loose connections and/or marring of the reader or adjacent structures. Accordingly, there remains a need for further contributions in this area of technology.
SUMMARY
One embodiment of the present invention is directed to a unique wiring connection for an access reader. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for connecting an access reader to wiring located within a structure. Further embodiment, forms, features, aspects, benefits, and advantages of the present invention shall become apparent from the description and figures provided herewith.

FIG. 1 is a schematic illustration of an access control system.
FIG. 2 is a view of an embodiment of an access reader including a connector.
FIG. 3 is a view of an embodiment of an access reader including a backplate.
FIG. 4 is a view of an embodiment of an access reader assembly.



DETAILED DESCRIPTION
For purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is hereby intended, any alterations and further modifications in the illustrated device, and any further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring to FIG. 1, shown therein is a conventional access control system 100 according to one form of the invention. System 100 includes a central access control 120 and a number of access control devices 140a, 140b. The central access control 120 is associated with an access control database 130 and a credential production system 110 that serves to generate access credentials. In a typical scenario, the central access control 120, the credential production system 110, and the access control database 130 are maintained by security personnel. The security personnel maintain the access control database 130 as a list of all persons authorized to enter various access points 150a and 150b on the premises. The access information associated with each person is gathered from the access control database 130 and is programmed into a blank access credential such as, for example, a smart card or proximity card, using access credential production system 110. Additionally or alternatively, the access production system 110 can be utilized to generate one or more access input codes, with each access input code being assigned to an individual or individuals, to be stored in the access control database 130. This programmed access credential or input code can then be used to access one or more of access points 150a, 150b via presentation to respective access control devices 140a, 140b which can be a card reader and/or a keypad mounted proximate to an access controlled door.
In the system 100, the individual access control devices 140a, 140b are configured to read access credentials. In response to a correct credential being presented to the access control devices 140a, 140b, an actuator (not shown) can be activated which is associated with the respective access points 150a, 150b. To make the determination to activate an actuator and thereby grant access, the access control device 140a, 140b reads the access credential and then transmits the credential or information derived from the credential to the central access control 120 where a look up function is performed. The lookup function can include accessing the access control database 130 to determine whether a credential presented at a given access control device 140 is authorized for accessing the access point 150 associated with the access control device 140. A message indicating the authorization status can be sent from the central access control 120 back to the access control device 140. In instances where the authorization is positive, the access control device 140 can communicate with the actuator of the access point 150 to grant the user access. Alternatively, the message indicating a positive authorization can be sent directly to the actuator of the access point 150 without passing through access control device 140. Other information may be transmitted between the access control device 140 and the central access control 120 to further enhance the integrity of the access control system 100, for example error codes indicating tampering, power failures, etc.
Referring to FIG. 2, shown therein is a rearward view of one embodiment of an access reader 200. The access reader 200 includes a case or housing 202. The housing 202 houses a printed circuit board (not shown) and other associated electronics (not shown) such that the reader 200 can receive and/or interpret one or more inputs from a card, keypad or other device, can communicate with and/or receive communications from the central access control 120, and/or can perform other desired functions. The access reader 200 can receive various inputs, such as from a multi-frequency smart card, a proximity card, and/or other radio-frequency identification (RFID) cards, devices, fobs, etc., examples of which are disclosed in commonly-owned U.S. Patent Application Publication No. 2011/0115603 filed Nov. 10, 2010, the contents of which are incorporated herein by reference. The access reader can further receive inputs from a keypad, keyboard, or other types of data input devices.

The cable 210 can pass through portions of a structure, such as through walls, conduit, etc., in order to provide electronic communications and signals to/from the access reader 200 and the central access control 120.
The connector 204 and the wiring harness 206 are retained in such a manner as to prevent a break in the electronic communication between the pins 228 and the receiving members 230. In one form, a projecting walled structure 216 surrounding the plurality of pins 228 is raised and is configured to be received within a recess 214 in a housing of the harness 206. The walled structure 216 can include sidewalk 240, 242 which are shorter than the sidewalk 250, 252. The sidewalls 240, 242, 250, and 252 can engage in a plurality of corresponding recesses (not shown) or a single recess 214 in the harness 206 so as to form a protective boundary to effectively isolate the electrical contacts from degradation due to environmental effects. In one specific form, the sidewall 252 can include a slot 251 to align with a corresponding tab 253 within the harness 206 to provide a keying feature structured to permit the harness 206 and connector 204 to mate in a single direction/orientation. The connector 204 can additionally or alternatively be retained in secure engagement with the harness 206 via one or more clips 208. The clips 208 are configured to lockingly engage with one or more corresponding recesses or notches 212 in the harness 206. The clips 208 can be tapered inwardly such that as the harness 206 is pressed onto the connector 204, the clips deflect outwardly and then snap back to engage the recess 212.
Additionally, the connector 204 and the harness 206 can include any number of pins 228 and receiving members 230 depending upon the application and the extent of electronic communications/signals to be transferred from or received by the access reader 200. In various forms, the connector 204 and harness 206 can include between four to twelve pin connections. In one specific form, the cable 210 includes twelve discrete wires, each connected to a corresponding one of the receiving members 230. In this form, the connector 206 can include a 4×3 array of pins 228, and the harness 206 can include a corresponding 4×3 array of receiving members 230, thereby forming a twelve pin connection as illustrated in FIG. 2. An illustrative example of electronic communications/signals transmitted across each wire/pin 228/pin receiving member 230 is shown in Table 1 below.
