DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) A secure electrical conductor connector 10, for the connection of electrical wiring as shown in FIGS. 1-6, comprises an electrical plug 20 formed on the end B of an insulated wire bundle A, an electrical socket 60 formed on the end B of another insulated wire bundle A, and a high contrast colored connection pin 100, the secure electrical conductor connector 10 establishing a removable and attaching connection between the insulated wire bundles A. This connection establishes a weatherproof secure connection, primarily used in motor vehicles and other transportation devices, including airplanes, boats and naval vessels, heavy machinery, construction equipment, utility trailers and other apparatus which are used outdoors and transporting electrical current with two or more wire connections.

(9) The electrical plug 20 further comprises a formed base 22, an extended collar 24 and shaped plug end 27 defining an outer surface 28 and a terminal face 29. The shaped plug end 27 may be rounded, oval, elliptical, square other geometric shape. Embedded within the terminal face 29 of the shaped plug end 27 are two or more bayonet sleeves 30, respectively connected to at least one wire within the insulated wire bundle A, which extends from the insulated wire bundle A through the electrical plug 20, with each bayonet sleeve 30 open towards the terminal face 29. The terminal face 29 provides a radial bevel 40 between the outer surface 28 of the shaped plug end 27 and the terminal face 29, FIGS. 2-4. On the outer surface 28 of the shaped plug end 27, there is one or more surface enhancements which provide a first element of the secure connection between the electrical plug 20 and the electrical socket 60 in the form of either a rounded radial groove 50 or a round radial expansion 52, depending on a mating surface enhancement of the electrical socket 60, FIGS. 1-5. Additionally, a radial bore 42 is defined within the shaped plug end 27, the radial bore 42 avoiding any impingement upon any of the embedded bayonet sleeves 30, FIGS. 2-5. On the extended collar 24 of the electrical plug 20, a sloped terminal margin 26 is presented at an edge 25 directed towards the shaped plug end 27, FIGS. 2-4.

(10) The electrical socket 60 further comprises a formed base 62, an outer resilient collar 63 having an internal surface 64 and an external surface 65 and forming a socket opening 66 extending into a socket base 67, FIGS. 1-4. The outer resilient collar 63 and socket opening 66 form an internal profile which can be rounded, oval, elliptical, square or other geometric shape conforming in size and shape to that of the shaped plug end 27 of the mating electrical plug 20. Extending from the socket base 67 are a plurality of bayonet conductors 70 which are respectively connected to at least one wire within the insulated wire bundle A, which extends from the insulated wire bundle A through the electrical socket 60, with each bayonet conductor 70 extending outward towards the socket opening 66, FIGS. 2-4. Each bayonet conductor 70 is oriented in size and shape to be inserted within a corresponding bayonet sleeve 30 within the electrical plug 20 when the electrical plug 20 and electrical socket 60 are engaged, forming a secure electrical connection between the insulated wire bundle A of the electrical plug 20 and the insulated wire bundle A of the electrical socket 60, completing the electrical wire connection, FIGS. 2-4.

(11) Between the internal surface 64 of the outer resilient collar 63 and the socket base 67, there is a beveled shoulder 68 confirming in shape and angle to the radial bevel 40 around the terminal face 29 of the shaped plug end 27 of the electrical plug 20, FIGS. 2-4. On the internal surface 64 of the outer resilient collar 63, there is one or more surface enhancements which provide a second element of the secure connection between the electrical socket 60 and the electrical plug 20 in the form of either a rounded radial groove 90 or a round radial expansion 92, depending on the mating surface enhancement of the electrical plug 20. The enhancements of the electrical plug 20 and electrical socket 60 are located so that upon connection of the electrical plug 20 and the electrical socket 60, at least one rounded radial groove 50, 90, receives and engages at least one on round radial extension 52, 92, which not only secures the electrical plug 20 within the electrical socket 60, but also acts as one of several weather-tight fittings which prevent intrusion of water and contaminants to the bayonet sleeve 30 and bayonet conductors 70 within the secure electrical conductor connector 10, FIG. 4, with each rounded radial groove receiving each round radial extension with complete, equal and conforming profiles.

(12) FIG. 3 is a cross-sectional view of a first embodiment of the secure electrical conductor connector 10 with a round radial expansion 52 on the outer surface 28 of the shaped plug end 27 and the rounded radial groove 90 within the outer resilient collar 63. FIG. 2 is a cross-sectional view of a second embodiment of the secure electrical conductor connector 10 with the round radial expansion 92 within the outer resilient collar 63 and the rounded radial groove 50 on the outer surface 28 of the shaped plug end 27. FIG. 4 is a cross-sectional view of the first embodiment in an assembled connection with the secured connection pin 100 inserted in the aligned radial bores 42, 80, of the outer resilient collar 63 and the shaped plug end 27. FIG. 1 is a perspective view of the first embodiment of the secure electrical conductor connector 10 indicating the respective insulated wire bundles A.

(13) The radial bore 80 is defined through the outer resilient collar 63 from the external surface 65 to the internal surface 64, aligning radially with the radial bore 42 of the electrical plug 20 during assembly, with the high contrast connection pin 100 inserting through the radial bore 80 of the electrical socket 60 into the radial bore 42 of the electrical plug 20 subsequent to connection of the electrical plug 20 and the electrical socket 60, FIGS. 4-5. At the socket opening 66 of the outer resilient collar 63, a reversed sloped terminal margin 69, conforming in size and slope to that of the sloped terminal margin 26 of the extended collar 24 of the electrical plug 20 but reversed in slope. This reversed sloped terminal margin 69 of the outer resilient collar 63 is presented to provide a secure conforming engagement with the sloped terminal margin 26 of the extended collar 24 of the electrical plug 20 when the electrical plug 20 and electrical socket 60 are engaged.

(14) As defined herein, there are numerous preventative measures contained within the secure electrical conductor connector 10, FIG. 4. First is the aforementioned one or more engagements of the surface enhancements within the electrical plug 20 and electrical socket 60. Second, the engagement between the reversed sloped terminal margin 69 of the outer resilient collar 63 and the sloped terminal margin 26 of the extended collar 24 of the electrical plug 20, which creates a conforming seal between the electrical plug 20 and the electrical socket 60. Third, the profile, size and shape of the shaped plug end 27 of the electrical plug 20 conforms to the profile, size and shape of the outer resilient collar 63 of the electrical socket 60, in such close proximity to prevent intrusion of water or contaminants, so much so that a lubricant may be useful in the connection process. Any and all of these preventative measures ensure that no outer elements can penetrate the seals created between the electrical plug 20 and the electrical socket 60 during secure connection. Additionally, the radial bevel 40 on the shaped plug end 27 when passing through the reversed sloped terminal margin 69 of the outer resilient collar 63 provides for easier insertion of the shaped plug end 27 of the electrical plug 20 into the outer resilient collar 63 of the electrical socket 60. As previously mentioned, an inert lubricant may be recommended applied to the internal surface 64 of the outer resilient collar 63 and/or the outer surface 28 of the shaped plug end 27, especially during an initial connection of the electrical plug 20 into the electrical socket 60. This lubricant, not shown, is also a preventative measure to prevent intrusion of water or contaminants within the assembled electrical plug 20 and electrical socket 60.

(15) Once the connection of the electrical socket 60 and electrical plug 20 have been established, the high contract colored connection pin 100, FIG. 6, is inserted through the radial bore 80 of the outer resilient collar 63 into the aligned radial bore 42 of the shaped plug end 27, FIGS. 4-5. In this regard the connection pin 100 defines a pin shaft 102, a pin head 104 and at least two radial expansion rings 106 along the pin shaft 102, as shown in FIGS. 4 and 6. The placement of the at least two radial expansion rings 106 is not random. The radial expansion ring 106 closest to the pin head 104 is located along the pin shaft 102 where when fully secured within the aligned radial bores 42, 80, this radial expansion ring 106 is positioned immediately below the internal surface 64 of the outer resilient collar 63, while the other existing radial expansion ring 106 is forcibly placed within the radial bore 42 of the shaped plug end 27, with each radial expanded ring 106 being greater in width than the inner diameter 44 of the radial bore 42 of the shaped plug end 27, FIG. 5. In furtherance of the placement of the connection pin 100, a pin head expansion 82 may be located in the radial bore 80 within the external surface 65 of the outer resilient collar 63, as shown in FIGS. 4 and 6, to limit the insertion of the connection pin 100 within the aligned radial bores 42, 80, to exact location of the radial expansion rings 106 to their intended location.

(16) While the primary inclusion of the high contrast colored connection pin 100 is to secure the aligned radial bores 42, 80, a secondary objective is to provide the pin 100 with a distinct color contrast with the electrical plug 20 and electrical socket 60 providing for quick inspection of the electrical connection, the pin 100 being of a distinctly contrasting color (white/black, yellow/black, red/black, etc.) to the color of the electrical socket 60 and electrical plug 20. This connection pin 100 is easily recognized during a cursory inspection of the secure electrical conductor connector 10 to visually confirm that the electrical plug 20 is securely connected within the electrical socket 60. If the pin is missing or not seen, then there is a visual alert that the electrical plug 20 and electrical socket 60 may not be secure or subject to intrusion of water or contaminating elements. If the pin 100 is present upon a visual inspection, there is immediate confirmation that the electrical plug 20 and electrical socket 60 are properly connected. Removal of the connection pin 100 should require intentional force and removal should be done prior to disconnection of the electrical plug 20 from the electrical socket 60 to prevent damage to the respective radial bores 42, 80, of the electrical plug 20 and especially the electrical socket 60.

(17) Alignment of the respective radial bores 42, 80, should require no effort due to the conforming shapes of the shaped plug end 27 and the internal surface 64 of the outer resilient collar 63 plus the alignment and integration of the bayonet sleeves 30 and the bayonet conductors 70, which are oriented in mirror image alignment and should only be connected with the electrical plug 20 and the electrical socket 60 in a singular position. Thus, the radial bores 42, 80, should be aligned any time the electrical plug 20 and electrical socket 60 are fully engaged. If they are not, an immediate connection problem should be noticed and connection should be attempted again. The number of bayonet conductors 70 and bayonet sleeves 30 should be aligned and purposeful, but not necessarily equal. It is known in the industry that there are examples of more sleeves 30 being included in electrical plugs than bayonet conductors 70 in certain cases where the plug is connected to fewer wires than the socket. However, it is not possible that the number of bayonet conductors 70 exceed the number of bayonet sleeves 30, which should be practically recognized by those skilled in the art of electrical connectors, because one cannot connect and plug and socket with fewer sleeves than conductors.

(18) Preferred materials for the components of the electrical plug 20 and electrical socket 60 are a resilient rubber or polymeric plastic, with the outer resilient collar 63 and the portion of the shaped plug end 27 providing the radial bores 42, 80, being resilient and momentarily deformable. The preferred material for the high contrast colored connection pin 100 is plastic or polypropylene. The required material for the bayonet sleeve 30 and the bayonet conductors 70 is a conductive metal, which are either soldered, welded or otherwise engaged with the respective metal wires (not shown) contained within the insulated wire bundles A.

(19) While the secure electrical conductor connector 10 has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the invention.
