Description

ELECTRICAL PLUGGE FIELD OF THE INVENTION The present invention relates to electrical devices and more particularly to an electrical plug, designed to inhibit another electrical plug, coupled or attached, from accidentally separating as a result of pulling forces accidentally exerted on an electrical cable. which extends from the other electrical outlet. BACKGROUND OF THE INVENTION Electrical plugs are commonly used with electrical cables or conduits and power supply cables. Typically, electrical outlets have two or more electrical contacts "that engage or join together.

For example, a power tool usually has an electric cable of relatively short length that extends with an electrical male plug at its end. The plug at the end of the power tool cable or conduit typically has a plug with at least two spring-type electrical female contacts adapted to receive in a releasable manner and electrically couple with two elongated male contacts or prongs projecting from an electrical male plug commonly disposed at the end of an elongated power supply cable. The contact force established between the spring-type electrical female contacts in the REF: 27291 female socket in an electric male plug and the pins * Male drivers of the other electric male plug, are all «that secures the electrical male plugs with each other. As will be appreciated by the majority who use 5 electrically powered tools, such as saws, drills, and outdoor landscaping equipment, the force that holds the electrical male plugs together is easily overcome during use, resulting in accidental separation of the male plugs with each other. The accidental separation of the electrical male plugs by establishing an electrical connection, for example between a tension cable and a tool or the like, is of particular interest in construction sites. In these applications, a worker can lose all power due to a plug accidentally separating from a cable connector located at a significant distance away from the site where the worker is currently located. In this way, when there is an accidental separation of a plug When a cable connector is used, the worker must stop doing what he was doing to connect the tool to the power source. This results in a waste of valuable time. Even more, requiring a worker to move into a job site to connect a power tool accidentally disconnected from A cable connector increases the likelihood of accidents and other accidental mishaps. To date, the most common remedy is to tie a knot in the cable, thus maintaining the plug in the cable connector. This supposed solution, however, has not always met with the greatest success. As will be appreciated, to potentially bind the electrical connection, potentially destructive forces are applied to the electric cables. This often results in a fire or shock hazard. In this way, there is a continuing need and desire for some form of means to prevent accidental separation of a pair of electrical sockets that form an electrical connection between two electric cables or conductors in the event of application of a separating or pulling force exerted accidentally, either in the cable or in the driver. # COMPENDIUM OF THE INVENTION As it is used to «through and through the description, The term "plug" is intended to denote a male or female electrical connector. Even more, and as it is used here and through it, the term or phrase "electrical conductor" or "electrical cable" is intended to denote either a connection cable or a cable supply.

In view of the foregoing and in accordance with the present invention, there is provided an electrical socket configured to inhibit accidental separation of an electrical cable that connects releasably. The electric plug 5 includes an electrifiable plug body, which has electrical contacts to which the electrical plug is to be releasably connected. According to one aspect of the present invention, the connector body includes as part of the The same, a protection against pulls to releasably attach a longitudinal portion of the electric cable to the body of the connector, in this way maintaining the electrical connection between the electrical contacts of the body of the connector and the electric cable. In this way, tensile forces exerted on the electric cable have significantly reduced effects on the electrical connection between the electric cable and the body of the connector. In one form of the invention, the protection against pulls on the body of the connector comprise a series of prongs extending from the body of the plug that combine to define a path of travel path for the longitudinal portion of the electric cable "which is held by the strain relief.

Surfaces at the tips "projecting from the plug body define a channel or elongated slot disposed adjacent to the body of the connector. The slot or elongated channel defined by the tips and in the plug body, allows the longitudinal portion of the electric cable between them. As will be appreciated, the channel defined by the surfaces at the tips is dimensioned and disposed relative to each other to hold an exterior of the longitudinal portion of the electrical cable between them. In a preferred form of the invention, the tips are formed integrally with the plug body. In a more preferred form of the invention, the channel defined in the plug body includes ingress and egress portions disposed substantially co-planar or in alignment with each other. The channel defined by the tips in the plug body further includes a middle portion that is displaced from the entry and exit end portions, such that the longitudinal portion of the electrical cable passing through the channel has a V-type configuration. and it inhibits end movement through the channel where tensile forces are exerted. The plug body of the electrical connector further includes structure for maintaining the longitudinal portion of the electrical cable adjacent to the body of the connector. Still further, the connector body of the electrical connector according to the present invention further includes a structure for releasably supporting the longitudinal portion of the electrical cable within the channel. The structure for maintaining the longitudinal portion of the electrical cable adjacent to the plug body and the structure for releasably supporting the longitudinal portion of the electrical cable within the channel, preferably integrally formed with the body of the connector. In another form of the invention, the protection against pulls on the connector body is configured to allow two power cables to be releasably passed in side-by-side relationship with each other. Alternatively, the connector body of the electrical connector of the present invention may include a second protection against pulls, to accept a longitudinal portion of another electrical cable. The second strain relief is configured in such a way that a longitudinal portion of the * Additional cable passes and is inhibited from moving by end through the protection against jerks when a force of traction is exerted. To make an electrical connection between the electric connector body and the electric cable, the connector body also includes at least two electrical contacts. As will be appreciated by those with skill in the specialty, the electrical contacts are elongated in a predetermined direction with respect to the body of the connector. In a preferred form of the invention, the longitudinal portion of the electrical cable passing through the strain relief passes over a path 5 extending generally parallel to the longitudinal direction of the electrical contacts. As such, a loop is formed as a portion of the electrical cable that passes between the outlet end portion of the strain relief and the electrical connector on the cable electrical after the electrical connector is coupled with the body of the connector. As will be appreciated, the loop in the electric cable also inhibits accidental separation of the electrical connection established between the electric cable and the connector body of the electrical connector of the present invention. Another salient feature of the present invention relates to an electrical connection when an electrical connector of the present invention is electrically connected to another electrical connector having a cable electrical projecting there. This aspect of the present invention involves having a male connector with a first electric cable extending from one side and a plurality of conductive pins extending therein in diametrically opposite relation to the cable and from one side opposite and a female connector having a second electrical cable extending therefrom, the second connector includes a connector body with a surrounding circumferential projecting edge, and with the second electrical cable extending away from the peripheral edge of the second. connector on a predetermined path, and wherein the female connector further includes a plug to releasably accommodate the male connector pins. In this form of the invention, the second electrical cable and the plug in the female connector are separated by an included angle of less than 180 °. As such, the male and female connectors are retained in coupling relationship with each other against tensile forces exerted on the first and second electrical cables that would normally cause separation of the connectors. Alternatively, the connector structure of the present invention may include a male connector having a first electric cable extending from one side and a plurality of conductive pins extending in diametrically opposite relationship to the cable and from its opposite side, and a female connector «that has a second electric cable that extends from there. The second connector includes a connector body with a circumferential peripheral extending edge, and with a second electrical cable extending away from the peripheral edge of the second connector over a predetermined path, and wherein the female connector further includes a plug * to releasably accommodate the male connector pins. In this form of the invention, the second electric cable and the plug in the female connector are separated by an included angle less than 180 °. Accordingly, the male and female connectors are retained in a coupling relationship with each other against tensile forces exerted on the first and second electrical cables that would normally cause separation of the connectors. These and other objects, goals and advantages of the present invention will be more readily apparent from the following detailed description of the invention, the claims and the appended drawings.

DESCRIPTION OF THE PRESENT INVENTION While the present invention is susceptible to modalities in various forms, a preferred embodiment of the invention is described in the drawings and will be described below, with the consideration that it will be understood that the present description provides an exemplification of the invention and that it is not intended to limit the invention to the specific embodiment illustrated. Now with reference to the drawings, in which like reference numerals indicate similar parts throughout the various views, an electrical connector according to the present invention is shown and fully represented by the reference numeral 10.

The electrical connector 10 of the present invention includes a connector body 12 having separate main surfaces 14 and 16. The connector body 12 further includes a peripheral edge 18 that joins the major surfaces 14 and 16. In a preferred form of the invention , the connector body 12 is of molded construction in one piece. In a more preferred form of the invention, the connector body 12 is formed from a conventional plastic or other convenient form of highly insulating composite material. As will be appreciated by those skilled in the art, other resistant insulating materials will likewise be sufficient to constitute the preferred one-piece plug body 12. The electrical connector 10 further includes at least two electrical contacts 20 and 22. In the illustrated form of The invention, and as illustrated in Figure 3, the electrical contacts 20, 22 include conventional electrically conductive metal pins 24 and 26 that are relatively rigid in construction. A longitudinal portion of each conductive pin 24, 26 is embedded within the connector body 12 while another rigid linear portion of each pin 24, 26 extends in a first direction away from the connector body 12 of the electrical connector 10. Each pin is electrically conductor 24, 26 defines an axis 25, 27 respectively, which extend generally parallel to each other. Although not specifically illustrated in the drawings, the power pins 24, 26 of the electrical connector 10 can be polarized by providing a flared tip or other convenient configuration and a non-flared tip for the other power pin. Convenient will also be sufficient without deteriorating or departing from the spirit and scope of the present invention Even more, instead of planar configurations, the energy pins 24, 26 may have an arched configuration if desired. illustrated in Figure 3, the electrical connector 10 may include a third pin electrically The conductor 28 extends generally parallel to the pins 24 and 26 and serves as a ground connection for the connector 10. When the connector 10 is used, the body of the connector 12 is electrified. In the illustrated form of invention, the electrical connector 10 further includes an insulated and flexible electrical cable 30. One end of the electrical cable 30 is operatively connected in a conventional and well known manner, to the electrical contacts 20 and 22 of the electrical connector 10. As illustrated in FIG. the Figures 1 and 2, the electrical conductor or cable 30 preferably extends from the peripheral edge 18 of the connector body 12 in the same direction as and generally parallel to the axes 25., 27 of the electrical contacts 20, 22, respectively. An opposite end of the conductor or electric cable 30 includes a conventional connector 32. In the illustrated form of the invention, the electrical connector 32 includes electrical contacts 34 and 36. Although the electrically conductive pins 35 and 37 are illustrated in the Jm 10 drawings , it will be appreciated that a plug (not shown) having electrical contacts 34 and 36 will be equally sufficient without deteriorating or deviating from the spirit and scope of the present invention. An outstanding feature of the connector electrical 10 of the present invention involves providing a strain relief 40 arranged in combination with the electrical connector 10. As illustrated ^ in Figures 4 and 5, the purpose of the strain relief 40 is to prevent another electrical connector 50 is accidentally separated from the electrical connector 10 after an electrical connection is established between the electrical contacts 20, 22 (Figures 1 and 3) of the electrical connector 10 and the electrical contacts (not shown) of the connector 50. That is, after that the connectors 10 and 50 are coupled, the purpose of the strain relief 40 is to inhibit a pulling force exerted on a second conductor or electrical cable 52, connected and operatively connected to the electrical connector 50, which has an adverse or separation effect of the electrical connection established between the connectors 10 and 50. Returning to Figures 1 and 2, the strain relief 40 is preferably configured as an elongated or open-sided groove or channel 42, defined in the connector body 12 of the connector 10. The slot or elongated channel 42 is sized to temporarily accommodate and hold or hold a longitudinal portion of the second electric wire 52 (Figures 4 and 5) to the body of the connector 12 of the electrical connector 10. The open-sided configuration of the slot or channel 42 easily allows insertion of a longitudinal portion of electrical cable 52 from the outside of the body of the connector 12. This is, the c The body of the connector 12 does not have to be divided or separated to secure a longitudinal portion of a second cable or conductor 52 to the electrical connector 10. As illustrated in Figure 1, the channel or groove 42 has an elongated configuration and is preferably disposes on the peripheral edge 18 of the body 12 of the electrical connector 10. In a more preferred form of the invention, the elongated groove or channel 42 defines a path extending generally parallel to the axes 25, 27 of the electrical contacts 20, 22 respectively and preferably extends parallel to that portion of the conductor or electrical cable 30, which projects immediately away from the body of the connector 12 or the connector 10. As illustrated in Figure 2, the channel 42 is specifically configured to inhibit that the longitudinal portion JP 10 of the cable 52 which is inserted passes end-to-end through the channel 42 in response to a pulling force exerted on the n the cable 52. The elongated channel or slot 42 includes an inlet portion 43 and an outlet portion 44. Furthermore, the elongated channel 42 that forms the strain relief 40 further includes a middle portion 45. # As illustrated in Figure 2, the input and output portions 43 and 44 respectively of the channel 42, are preferably arranged in general alignment with each other. In other words, the input and output portions 43 and 44 respectively of the channel 42 are preferably coplanar to each other. Notably, the middle portion 45 of the channel 42 is displaced from either the inlet portion 43 or the outlet portion 44 of the channel 42. The travel ratio of the middle portion 45 of the channel relative to the opposite ends 43, 44 defines a F tortuous path 46 for the longitudinal portion of the cable 52 inserted there. That is, and after being inserted into the strain relief 40, the longitudinal portion 5 of the cable 52 disposed between the inlet portion 42 and the outlet portion 44 of the channel 42 is forced into a tortuous configuration. Turning again to Figures 1 and 2, the strain relief 40 on the connector body 12 10 of the electrical connector 10 preferably includes a series of tips or extensions 60, 62 and 64 projecting from the peripheral surface 18 of the body connector 12 of connector 10. As will be appreciated, and in combination with each other, the tips or extensions 60, 62 and 64 define the trajectory tortuous 46 of the channel 42 in the body of the connector 12 and in which a longitudinal portion of the second electrical conductor or cable 52 is trapped against longitudinal movement. The tips or extensions 60, 62 and 64 are relatively rigid construction to withstand the arduous environment in which the electrical connector 10 can find utility. In a more preferred form of the invention, the tips or extensions 60, 62 and 64 are integral with or as part of the body of the connector 12.

As illustrated in Figure 2, the surfaces 61 and 65 at the tips 60 and 64, respectively and the opposing surface 63 at the tip 62, serve operationally to frictionally engage and hold the outer surface configuration of the longitudinal portion of the cable or electrical conductor 52 adapted to be coupled by the strain relief 40. Still further and as will be appreciated from a proper understanding of the present invention, the opposite surfaces 10 61, 62 and 65 of the tips 60, 62 and 64 respectively they are dimensioned and arranged to frictionally grip the outer surface of the second cable 52 therebetween. The electrical connector 10 of the present invention further includes a structure 70 for releasably supporting the longitudinal portion of the second. conductor 52 within the strain relief 40. As illustrated in Figures 6, 7 and 8, the structure 70 comprises a flange-like formation 72 at the end is distant from each tip or extension 60, 62 and 64. Notably, a predetermined distance is established between an inner surface 74 of each flange-type formation 72 at the distal end of the tips 60, 62 and 64 and the peripheral edge 18 of connector body 12.

In a preferred form of the invention, the * predetermined distance between the flange type formation 72 at the far end of each point 60, 62 and 64 varies from end to end. This is, in a more preferred form of the , the predetermined distance "separating the flange-type formation 72 at the tip end 60 may be more or less than the predetermined distance separating the flange-type formation 72 at the distal end of the tips 62 and 64. Further, the predetermined distance tg 10 separates the flange-type formation 72 at the distal end of the tip 62 is preferably different than the predetermined distance separating the flange-type formation 72 at the distal ends of points 60 and 64. Differences in distances predetermined that separate the formations type flange at the ends of the tips 60, 62 and 64 defines the direction «that the longitudinal portion of the cable ^ Electrical 52 directs through protection channel 42 Ff against jerks 40. As will be appreciated, with some manual and intended handling, the second driver 52 can move forcing beyond the structure 70 if so desired to remove or release the longitudinal portion of the second cable or conductor 52 of the strain relief 40 of the electrical connector 10. The electrical connector 10 of the present invention further includes the structure 80 , to releasably support the longitudinal portion of the second • conductor or cable 52 adjacent the peripheral surface 18 of the connector body 12 of the electrical connector 10, thereby reducing the likelihood that the electrical connection between the connectors 10 and 50 will accidentally be separated. As illustrated in Figures 6, 7 and 8, the structure 80 preferably includes a curved or sloping surface 82, configured at the distal end of each extension or point 60, 62 and 64. chamfered or sloped surface 82, preferably is disposed on an inner surface of each flange type formation 72 at the tips 60, 62 and 64. Suffice it to say that the angled or curved surface 82 of the structure 80 is configured to engage and move or move the portion longitudinal of the second cable 52 trapped by the strain relief 40 towards the peripheral edge 18 of the connector body 12. * In this form of the invention and as illustrated in Figures 4 and 5, the electrical connectors 10 and 50 are electrically connect to each other in such a way that the contacts 20, 22 associated with the connector 10 are electrically connected to the electrical contacts of the connector 50. In addition, a longitudinal portion of the electrical conductor or cable 52 associated with the connector 50 is trapped within of the strain relief 40 of the electrical connector 10 thereby preventing accidental separation of the connectors 10 and 50. In the embodiment of the invention illustrated in Figures 4 and 5, a longitudinal portion of the electrical cable 52 is braided with the tips or extensions 60, 62 and 64 of the connector body 12, such that the longitudinal portion of the cable 52 connected to the connector 50 is passed through a tortuous path, thereby inhibiting movement of the end of the cable 52 through the the strain relief 40, in response to a tensile force or tensile stresses exerted on the cable 52. More specifically, in the illustrated form of the invention with a portion of the cable 52 passes through both the inlet and outlet portions 43 and 44 of the trough protection channel 42. It is important to note, however, that "between the input and output portions 43 and 44, a longitudinal portion of the cable or connector 52 is required to pass around the middle portion 45 of the channel 42, thereby feeding a shape to the longitudinal portion of the cable 52 trapped in the strain relief 40. As such, the frictional engagement of the outer surface of the longitudinal portion of the connector or cable 52 with the opposite surfaces 61, 63 and 65 defined by the channel or slot 42 inhibits the movement of end of the connector or cable 52 with respect to the connector body 12, thereby protecting the electrical connection between the connectors 10 and 50. As illustrated in Figure 4, a portion of the cable 52 passes between the outlet portion 44 of the strain relief 40 and the connector 50. In the illustrated form of the invention, the path of travel of the longitudinal portion of cable 52 trapped by the strain relief 40, extends generally parallel with the electrical contacts 20, 22 in the connector 10. Accordingly, a loop 90 is formed in that longitudinal portion of the second conductor or cable 52 passing between the outlet end portion 44 of the strain relief 40 and the connector 10. The-providing a loop 90 further inhibits the connectors 10 and 50 from accidentally separating from each other, in response to tensile stresses or pulling force imparted to the second wire 52. Another embodiment of the electrical connector according to the present invention is illustrated in Figure 9. The alternating shape of the electrical connector illustrated in Figure 9 is generally designated by reference numeral 110. The elements of this alternating form of electrical connector which are identical or functionally analogous to those components mentioned above with respect to the electrical connector 10, are designated by reference numerals identical to those previously employed except that this mode uses the reference numbers in the 100 series. The electrical connector 110 includes e a connector body 112, substantially similar to that described above with respect to the connector body 12. In this embodiment of the invention, the connector body defines an electrical socket 119 that includes electrical contacts 120, 122. Each electrical contact 120, 122 includes members mm. 10 conventional electrically conductive conductors 124 and 126 embedded within the connector body 112 of the connector 110. As is well known in the art, members 124, 126 of each electrical contact 120, 122 spring toward each other but separate from each other when a male conductor pin of another electrical connector is inserted between them. The conductor members 124, 126 of each electrical contact 120, 122 are operatively and electrically connected in a conventional manner to an electrical cable conductor 130 extending far from the edge. peripheral 118 of the connector body 12 of the electrical connector 110. The electrical connector 110 further includes a strain relief 140. The strain relief 140 is substantially similar to the protection against jerks 40 discussed in detail above. Thus, no further detailed description is required for a complete understanding of the function and operation of the strain relief 140. Another embodiment of the electrical connector according to the present invention is illustrated in Figures 10 to 13. The alternate form of The electrical connector shown in Figures 10 to 13 is generally designated by the reference numeral 210. The elements of this alternating form of electrical connector that are identical or functionally analogous to those aforementioned components with respect to the electrical connector 10, are designated by numbers references identical to those previously employed except that this embodiment uses reference numbers in the series 200.

The connector body 212 defines a plug 219, which includes conventional electrical contacts 220 and 222. Each electrical contact 220, 222 includes conventional electrically conductive members 224 and 226 embedded within the connector body 212 of the connector 210. As is well known in FIG. Technically, the members 224, 226 of each electrical contact 220, 222 spring toward each other but are separable from each other when a male lead pin of another electrical connector 250 is inserted therebetween. The conductor members 224, 226 of each electrical contact 220, 222 are operatively and electrically connected to a conventional manner with an electrical wire or cable 230"extending away from the peripheral edge 218 of the connector body 212 of the electrical connector 210. The body of the connector 212 includes a first strain relief 240 longitudinally disposed to the peripheral edge 218 of the body of the connector 212. As illustrated by tj-10, the strain relief 240 defines an elongated groove or channel 242 to accommodate a longitudinal portion of the cable. or electrical connector 252 operatively associated with the electrical connector 250. The strain relief 240 preferably includes a plurality of tips or extensions 260, 262 and 264 that are combined together to define a tortuous path 246 for the longitudinal portion of the electrical cable 252 trapped therein. As illustrated, the tortuous path defined by points 260, 262 and 264, preferably configures the electric cable trapped between them in a line other than straight. The tips 260, 262 and 264 and the channel or groove 242 defined therebetween are substantially similar to those described above with respect to tips 60, 62 and 64 and channel 42 defined in this way.

In this form of the invention, a second * strain relief 240 'is also disposed in the connector body 212. The second strain relief 240' is substantially similar to the strain relief 240 disposed on an opposite side of the connector body 212. As illustrated, the groove or elongate channel 242 of the strain relief 240, extends generally parallel to an elongated groove or channel 242 'defined by flip protection 10 240' to capture a longitudinal portion of a third conduit or electrical cable 252 'passing adjacent to connector body 212 of electrical connector 210.

As will be described in detail below, and in connection with another form of the present invention, the included angle less than 180 ° * between the electric cable 430 and the axes 425, 427 of the electrical contacts, serves to retain an electrical connection between a male connector and the female connector 410. As such, when imparting tensile stresses or a pulling force to the electric cable associated with the male connector electrically connected to the female connector 410, the connectors are directed in coupling with each other, thereby improving the electrical connection established between them. Another embodiment of an electrical connector according to the present invention is illustrated in Figure 17. The alternating form of the electrical connector shown in Figure 17 is generally designated by the reference number 510. The elements of this alternate form of the The electrical connector, which are identical or functionally analogous to those components mentioned above with respect to the electrical connector 10, are designated by reference numerals identical to those previously used except that this mode 5 uses reference numbers in the 500 series. electrical connector 510 includes a connector body 512 substantially similar to that described above with respect to the connector body 12. In this embodiment of the invention, the connector body 512 -J 10 defines at least two electrical contacts 520, 522. Electrical contacts 520, 522 are illustrated to include conventional electrically conductive pin members 524 and 526, a linear portion of each embedded within the connector body 512 of the connector 510. As well known in the art, the pin members 524, 526 of the electrical contact 520, 522 are operatively and electrically connected in a conventional manner to the conductor or electrical cable 530"extending away from the peripheral edge 518 of the connector body 512 of the connector electric 510. Notably, each contact 520, 522 has an elongated formation defining axes 525, 527 for contacts 520, 522, respectively. As illustrated in Figure 17, the electrical conductor or cable 530 of Preferably it extends from the peripheral edge 518 of the body of the connector 512 in the same plane as the electrical contacts 520, 522, respectively. As illustrated in the drawing, at least that portion of the electrical cable 530 immediately adjacent the connector body 512 extends in a predetermined direction or path from the electrical connector 510. The electrical cable 530 extends from the body of the connector 512 and the axes 525, 527 defined by the electrical contacts 520, 522 define an angle included less than 180 ° between them. As will be described in detail below, the included angle less than 180 ° between the electric cable 530 and the axes 525, 527 of the electrical contacts serves to retain an electrical connection between the male connector 510 and a female connector.

As such, when tensile stress or tensile force is imparted to the electric cable associated with the female connector electrically connected to the male connector 510, the connectors are directed in coupling with each other, thereby improving the established electrical connection among them.

Accordingly, when pulling forces are accidentally exerted on the cable, the strain relief inhibits the electrical cable that disconnects the electrical connection between the connector disposed at the free end of the cable and the connector electrified of the present invention. Furthermore, the strain relief is configured to allow electric cables of different sizes to be threaded in a different direction while allowing the same 5 benefits to be achieved - to inhibit the cable from moving end-to-end through the strain relief. Even more, the strain relief can be configured to allow cables in side-by-side relationship with each other, if so _ is required. Alternately, the electrical connector of the The present invention can be configured with dual plug receptacles and one or more pull protections to accommodate a longitudinal portion of each connected electrical cable.
