DESCRIPTION
(11) A wire cut and tap device 10, as described herein, is designed to cut into and tap an existing wire in an electrical system in a relatively quick and non-invasive manner. For example, the device may be used to cut into and tap a wire in an existing vehicle wiring system. The device, once installed, allows the user to make high quality professional connections to a wiring harness without compromising the integrity of the wiring system. The device (which may also be referred to herein as a switch arrangement device or a wire cut and tap with bypass feature) allows the user to add electronic modules and other electronic accessories to the wiring system (e.g., a vehicle wiring system). These accessories may be removed later without leaving the wiring harness compromised. Furthermore, the device is designed to quickly and easily restore the vehicle wire circuits to stock condition upon the simple flip, transition or other manual actuation of a switching arrangement.
First Exemplary Embodiment
(12) With particular reference to
(13) The wire passage 20 is generally cylindrical in shape and is configured to receive a wire (of a maximum wire gauge) and allow it to extend completely through the device 10 from a first end 18a to a second end 18b. When the mouth 16 is open, the wire passage 20 is provided as an open half-cylinder extending through the interior of each half of the housing 12. An existing wire/conductor 22 of an electrical circuit may be placed in the open mouth 16 of the housing 12 and situated in the wire passage 20. The mouth 16 may then be closed to trap the wire 22 in place within the housing 12.
(14) With reference now to
(15) With continued reference to
(16) The electrically non-conductive material may be provided by a material that has a sufficient insulation factor and thickness to block the flow of electricity in an appropriately rated circuit. In at least one embodiment, the non-conductive material 32 is a nonconductive epoxy of phenolic plastic or a ceramic coating. The non-conductive material is provided as a relatively thin layer on the blade 30 so as not to interfere with the cutting action of the blade 30. In the embodiment disclosed herein, the non-conductive material 32 is provided as a layer that covers an entire side of the blade 30. In at least one alternative embodiment, the non-conductive material may be provided as two different layers that sandwich the blade 30, leaving the sharp tip of the blade exposed.
(17) With continued reference to
(18) The electrically conductive protrusions 40 are provided as sharp metal prongs in the embodiment of
(19) The internal portion of the housing 12 also includes gripping teeth 42 molded into the plastic shell interior that assist in retaining the severed conductor ends 23a and 23b securely in place. The gripping teeth 42 are comprised of a generally non-conductive and relatively resilient material such as a TPU or other elastomer. The gripping teeth 42 may be blunt or sharp, but the resilient material used to form the gripping teeth 42 provides a surface with a high coefficient of friction, and this surface engages the insulator surrounding the wire 22 and retains the wire 22 in place within the wire passage 20.
(20) As noted previously, the two terminals 52a and 52b provide an electrical connection path to the sharp metal protrusions 40. In at least one embodiment, the terminals 52a and 52b are female spade terminals positioned in connector slots 50a and 50b on either end 18a, 18b of the clam shell housing 12. These slots 50a and 50b allow a lead with a connector attached thereto, such as a male spade terminal, to be press fit into the plastic housing 18 and connect to the female spade terminals 52a, 52b. In at least one embodiment, the male spade terminal may simply be the end of a relatively rigid conductor wire providing the lead to the device 10. If the male spade terminals are connected to an electronic component accessory (as described in further detail below), first electrical path is provided to the first severed end 23a of the wire 22 by the first terminal 52a, and a second electrical path is provided to the second severed end 23b of the wire 22 by the second terminal 52b. Electrical current may then flow from the first severed end 23a of the wire 22, through the connected module, and then to the second severed end 23b of the wire 22.

(31) The leads 121 may be used to easily connect or disconnect the circuit of an electronic accessory to or from a circuit including the wire extending through the device 10. In particular, when the leads from the electronic accessory are inserted into the slots 50, the switching arrangement 60 is opened and the electronic accessory may be inserted in series in the line provided by the wire extending through the device 10. When the electronic accessory is to be removed, the two leads from the electronic accessory are removed from the slots 50, and the switching arrangement is closed, returning the circuit to its original condition without the electronic accessory.
(32) As shown in
(33) As discussed previously, the dimensions of the components of the device 10 may vary depending on the gauge of the wire for which the device 10 is intended. As shown in 6A, the housing 12 includes dimensions d.sub.1 and d.sub.2. In at least one embodiment d.sub.1 may be between 0.75 inches and 1.5 inches, and particularly about 1 inch. In such embodiment, d.sub.2 may be between 0.25 and 0.75 inches, and particularly about 0.5 inch.
(34) Exemplary Application for Device in Automotive Aftermarket
(35) With reference now to
(36) An exemplary lighting control module 120 is disclosed in U.S. patent application Ser. No. 14/301,078, filed Jun. 10, 2014, the contents of which are incorporated herein by reference in their entirety. In such embodiment, the lighting control module 120 is an adaptive shunt that also includes a connection to the supply line 114 of the brake light circuit 110. However, it will be recognized that the lighting control module 120 shown in

(38) As shown in
(39) The wire cut and tap device 10 described herein may be used to quickly and easily install an electronic accessory such as the lighting control module 120 in the brake light circuitry of an automobile. The device 10 allows the installer to add the lighting control module to the vehicle without the need to cut and strip any existing wires in a wiring harness. Instead, the installer simply clamps the device 10 onto the appropriate wire and plugs the lighting control module into the device. After this simple installation, the user is provided with an aftermarket arrangement wherein the brake lights provide a pulsing feature, as described above with reference to
(40) Should the owner of the vehicle ever decide that the lighting control module 120 is not desirable, the lighting control module 120 may be easily removed from the brake light circuitry by simply adjusting the switching arrangement 60 on the wire cut and tap device 10. When the user transitions the switching arrangement 60 from the first position to the second position (i.e., from the include additional circuitry position to the return to original connections position), the lighting connections to the control module 120 are terminated, and the original connections on the vehicle brake light circuitry are reinstated. In this manner, a user incorporating an aftermarket module into a circuit using the wire cut and tap device 10 described herein may easily remove the added aftermarket module with little or no additional work.
(41) While the wire cut and tap device 10 has been described herein as being used in association with an automotive brake light system, it will be recognized that the device 10 may also be used in any of various other wiring arrangements when installing any of various electronic accessories to an electrical circuit. Examples of other applications exist across various platforms and industries, including any of various other residential, commercial, industrial, automotive, or personal appliance applications. Exemplary applications include residential and commercial automation equipment, residential and commercial security equipment, lighting systems, appliances, etc. Moreover, it will be recognized that the foregoing detailed description of one or more exemplary embodiments of the wire cut and tap with bypass feature has been presented herein by way of example only and not limitation. It will be recognized that there are advantages to certain individual features and functions described herein that may be obtained without incorporating other features and functions described herein.
