The disclosure relates to terminal devices and more particularly pertains to a new terminal device for attaching a conductor to an electrical circuit. The device includes a terminal which has a curved portion and a retainer that is engaged to the terminal. The retainer is spaced from the terminal to define a conductor space between the terminal and the retainer. Additionally, a sheath is positioned around the terminal and the retainer. The curved portion of the terminal and the retainer abuts the conductor when the conductor is inserted into the conductor space to place the conductor into electrical communication with the electrical circuit.
The prior art relates to terminal devices including a crimpless electrical connector that includes a terminal and a flap that is spaced from the terminal. A conductor is insertable between the terminal and the flap having the flap engaging the conductor at an angle to inhibit the conductor from being removed from the crimpless electrical connector. The prior art discloses a wire coupler that includes a pair of fingers that receive a first conductor and a socket that receives a second conductor for placing the first conductor into electrical communication with the second conductor. The prior art discloses a wire splice that includes a pair of opposing sockets, each having a tab being integrated therein, which each insertably receives a respective one of a pair of wires for splicing the pair of wires together. The prior art discloses a terminal block which has a socket for insertably receiving a conductor and a plurality of contacts in the terminal block.
An embodiment of the disclosure meets the needs presented above by generally comprising a terminal which can be attached to an electrical circuit. A retainer engages the terminal which defines a conductor space between the retainer and the terminal. The conductor space insertably receives an end of a conductor. The retainer is biased toward the terminal to compress the conductor between the terminal and the retainer. Each of the retainer and the terminal is comprised of an electrically conductive material to facilitate electrical communication between the conductor and the electrical circuit. A sheath is positioned around the terminal and the retainer to inhibit electrical communication between the conductor and external objects.

The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The terminal 12 has an opening 32 extending between the top surface 28 and the bottom surface 30 such that the opening 32 defines the connection point 14. The opening 32 is positioned adjacent to the first end 18, and each of the first lateral side 24 and the second lateral side 26 curves outwardly from an axis extending between the first end 18 and the second end 20 at a point that is aligned with the opening 32. The first lateral side 24 has a first slot 34 extending toward the second lateral side 26 and the first slot 34 is positioned between the opening 32 and the second end 20. The second lateral side 26 has a second slot 36 extending toward the first lateral side 24 and the second slot 36 is aligned with the first slot 34.
The curved portion 16 includes a first bend 38 defining a vertical portion 40 of the terminal 12 that is perpendicularly oriented with a first horizontal portion 42 of the terminal 12. The first bend 38 is positioned between the first slot 34, the second slot 36 and the second end 20 of the terminal 12. Continuing, the curved portion 16 includes a second bend 44 which defines a second horizontal portion 46 which is perpendicularly oriented with the vertical portion 40. The second horizontal portion 46 lies on a plane that is oriented parallel with the first horizontal portion 42. The curved portion 16 includes a curve 48 extending between the second horizontal portion 46 and the second end 20, and the curve 48 extends upwardly from the second horizontal portion 46.
A retainer 50 is provided which engages the terminal 12 having the retainer 50 being spaced from the terminal 12 to define a conductor space 52 between the retainer 50 and the terminal 12. Moreover, the conductor space 52 insertably receives an end 54 of a conductor 56. The conductor 56 may be an insulated electrical wire that has insulation stripped away to expose wires of the electrical wire which may be wires of any conventional American wire gauge. The retainer 50 is biased toward the terminal 12 to compress the conductor 56 between the terminal 12 and the retainer 50. Each of the retainer 50 and the terminal 12 is comprised of an electrically conductive material to facilitate electrical communication between the conductor 56 and the electrical circuit.
The retainer 50 has a primary end 58, a secondary end 60 and an exterior surface 62 extending between the primary end 58 and the secondary end 60. The exterior surface 62 has an upper side 64 and a lower side 66, and the retainer 50 has an outside edge 68 extending between the primary end 58 and the secondary end 60. The outside edge 68 has a first sidelong side 70 and a second sidelong side 72. The retainer 50 has a flap 74 that is integrated into the upper side 64 and the lower side 66 of the exterior surface 62, and the flap 74 extends upwardly from the upper side 64. Furthermore, the flap 74 has a free end 76 that is directed toward the primary end 58 of the retainer 50.
Each of the first sidelong side 70 and the second sidelong side 72 angling outwardly between the primary end 58 and the secondary end 60 such that the secondary end 60 has a width is greater than a width of the primary end 58. The retainer 50 has a first tab 78 extending downwardly from the first sidelong side 70 and the first tab 78 is positioned adjacent to the primary end 58. The retainer 50 has a second tab 80 extending downwardly from the second sidelong side 72 and the second tab 80 is positioned adjacent to the primary end 58. Each of the first tab 78 and the second tab 80 engages a respective one of the first slot 34 and the second slot 36 having the retainer 50 sloping upwardly from the terminal 12.
A sheath 82 is provided and the sheath 82 is positioned around the terminal 12 and the retainer 50. The sheath 82 surrounds the conductor 56 when the conductor 56 is inserted into the conductor space 52. The sheath 82 is comprised of an electrically insulating material to inhibit electrical communication between the conductor 56 and external objects.
The sheath 82 has a front end 84, a back end 86 and an outside wall 88 extending between the front end 84 and the back end 86. The outside wall 88 is continuously arcuate about an axis extending between the front end 84 and the back end 86 such that the sheath 82 has a cylindrical shape. The outside wall 88 flares outwardly between the front end 84 and the back end 86 such that the back end 86 has a diameter that is greater than a diameter of the front end 84. The back end 86 is open and the front end 84 has a slot 90 extending through the front end 84. The terminal 12 extends through the slot 90 having the connection point 14 being exposed with respect to the sheath 82. Moreover, the second end 20 of the terminal 12 and the secondary end 60 of the retainer 50 is positioned within the sheath 82.
In alternative embodiment 92 as is most clearly shown in
In use, the conductor 56 is inserted into the back end 86 of the sheath 82 such that exposed wires 98 of the conductor 56 slide into the conductor space 52 defined between the terminal 12 and the retainer 50. In this way the exposed wires 98 abuts the curve 48 on the terminal 12 and the flap 74 on the retainer 50 such that the exposed wires 98 are in electrical communication with the terminal 12 and the retainer 50. Furthermore, the terminal 12 is urged downwardly from the retainer 50 and the retainer 50 is urged upwardly from the terminal 12 when the exposed wires 98 are inserted into the conductor space 52. In this way the terminal 12 and the retainer 50 are compressed against the exposed wires 98 to inhibit the exposed wires 98 from being pulled outwardly from the conductor space 52. Additionally, the flap 74 is urged upwardly by the exposed wires 98 such that the flap 74 compresses against the exposed wires 98 to further secure the exposed wires 98 in the conductor space 52.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
