Title: Cable connector having removable coded rings

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a cable connector and, more particularly, to a cable connector which can be attached to a cable to enable the cable to be connected to an electronic component and which includes a plurality of removable coded rings to identify the cable and the component. 
     Merging video systems with high quality audio systems is becoming increasingly popular. In these installations, several output, or program, sources are available, such as compact disc players, cassette decks, FM tuners, all of which have two stereo outputs; as well as laser disc players, stereo video cassette recorders (VCRs), and satellite receivers, all of which have a video output and two stereo audio outputs. These outputs are usually connected to an input source such as a stereo receiver, amplifier, preamplifier, processor or decoder (hereinafter referred to as &#34;receiver&#34;), which performs switching and processing functions and which includes a power amplifier, or an output to a power amplifier, for driving loudspeakers. The video output of the receiver is routed to a television monitor, or the like, having a video input. 
     The audio and video outputs of each of the above-mentioned program sources, as well as the corresponding inputs of the receiver, each receive a coaxial connector, often termed a &#34;RCA&#34; connector, which is standard in the industry. Thus, at least two, and sometimes three, cables each provided with a RCA connector at each end, are connected between the program source and the receiver. Still additional cables are needed when one of the program sources, such as a satellite receiver or laser disc player is connected to the input of a VCR for recording the video and audio signals, and the output of the VCR is connected to the receiver. 
     It can be appreciated with several program sources connected in the above manner, a multitude of cables are required which, along with speaker wires, AC power cords and antenna cables, result in a maize of cables, wires and cords which renders it difficult, if not impossible, to identify the cables and maintain a neat and organized installation. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide a connector for attachment to a cable which enables the cable, and the component associated with the connector, to be identified. 
     It is a further object of the present invention to provide a connector of the above type in which a plurality of removable rings are provided on the connector which are coded in a manner to enable the cable and its associated component to be identified. 
     Towards the fulfillment of these and other objects, the connector of the present invention includes a housing for receiving a cable and a pin supported by the housing for engaging a jack of an associated electronic component. A plurality of removable rings are provided on the housing and are coded to enable the particular cable and its associated component to be identified in an audio/video system. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The above brief description, as well as further objects, features and advantages of the present invention will be more fully appreciated by reference to the following detailed description of the presently preferred but nonetheless illustrative embodiments in accordance with the present invention when taken in conjunction with the accompanying drawings wherein: 
     FIG. 1 is an perspective view of the connector of the present invention; and 
     FIG. 2 is an elevational view of the connector of FIG. 1. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIG. 1 of the drawings, the reference numeral 10 refers, in general to the connector of the present invention which consists of an elongated tubular housing 12 having a tapered leading end portion 12a, a tapered trailing end portion 12b and a center portion 12c of a slightly reduced diameter. The end portion 12b receives a cable 14 (FIG. 2) which includes a center conductor for carrying the positive portion of an audio or video signal, an inner sheath of insulative material surrounding the center conductor, a conductor having an annular cross-section extending around the inner sheath for carrying the negative portion of the signal, and an outer sheath surrounding the latter conductor. Since this type of cable is conventional, it is not shown in detail in the drawings nor will it be described in any further detail. 
     To connect the cable to the housing 12, the insulation is stripped from an end portion of the cable to expose the above-mentioned conductors, the latter end portion is inserted into the end portion 12b of the housing 12 and the conductors are soldered, or otherwise connected to appropriate terminals (not shown) provided on the inner surface of the housing. 
     A pin 16 projects from the end portion 12a of the housing 12 and is supported within the housing in a conventional manner. The pin 16 is adapted to engage a jack provided on an electronic component as will be described. 
     Referring to FIG. 1, four spaced grooves 12d, 12e, 12f and 12g are formed on the outer surface of the housing 12 and are equally spaced between the end portion 12b and the reduced-diameter portion 12c. Four o-rings 18a, 18b, 18c and 18d, each fabricated of an elastic material, are insertable in the grooves 12d, 12e, 12f and 12g, respectively. The rings 18a, 18b, 18c and 18d are of an elastic or other stretchable material and are sized to enable them to firmly engage the outer surface of the housing 12, yet be quickly removed therefrom. 
     The o-rings are color-coded to identify the particular cable 14 and, more particularly, the components of an audio/video system to which the cable is to be connected. For example, the color of the ring 18a can identify the particular source component such as, for example, a compact disc player, while the color of the ring 18b can identify the component, such as a stereo amplifier, to which the disc player is to be connected. The color of the ting 18c can identify the particular stereo channel (left or tight), and the color of the ring 18d can identify the other stereo channel. Of course, another connector can be attached to the other end of the cable 14 and provided with the removable rings to provide color coding for the other component to which it is attached. 
     Thus the connector of the present invention permits a connection between two components in an audio system in a manner to enable the components and the particular connections to the components to be easily identified. Of course, each connector can be supplied with a plurality of differently coded O-Rings so that the coding on a particular connector can be changed if the component to which it is connected is changed. 
     It is understood that several variations may be made in the foregoing without departing from the scope of the invention. For example, the particular coding scheme can vary and the number of rings can vary depending on the particular coding scheme involved. Also, the particular type of connecter is not limited to the RCA connector described above, but could include other connectors known in the audio and video connector art such as balanced (XLR) connectors, and the like. Further the rings can be coded in manners other than by color. For example, other identifying indicia, such as numbers, letters or the like can be provided on the rings to provide the coding discussed above. 
     Other modifications, changes and substitutions are intended in the foregoing disclosure and in some instances some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
