This invention pertains generally to a wire stripping apparatus, and more particularly to an apparatus for stripping insulation from wire so that the inner metal conductor is removable for use or recycling.
Traditional wire strippers are heavy, bulky, and expensive, making it difficult for the average individual to economically strip wire safely to prepare it for recycling. As it is difficult to strip wires cleanly of their insulation to access the surrounding copper, individuals often attempt to remove the insulating layer by burning it off, thereby releasing dangerous chemicals into the environment and creating an inhalation hazard. Burning wires may be illegal in many areas, making it difficult to inexpensively strip the insulation off of large amounts of copper wire. Others may attempt to use a sharp knife to remove the insulating layer, which can easily result in injury. Unless the copper is separated from the insulation, the wiring must typically be disposed of as trash instead of being recycled.
Consequently, there exists a need for a safe economical tool for removing the insulating outer layer from copper wiring. The present invention discloses an apparatus capable of stripping wires so that only the inner conducting layer remains exposed and intact. The apparatus allows a user to easily strip the outer insulation and jacket from wires of a wide variety of diameters so that the inner copper may be safely removed and recycled.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed invention. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one aspect thereof, comprises a wire stripping apparatus. The wire stripping apparatus comprises a plurality of rectangular components secured together into a housing assembly. A plurality of continuous openings is located between the plurality of rectangular components in which a wire is insertable. As the wire passes into one the plurality of continuous openings, one of a plurality of cutting blades penetrates an outer insulating layer of the wire. After the wire emerges, the user simply pulls the insulating layer off of an inner metal conductor.
Furthermore, in a preferred embodiment of the invention, the wire stripping apparatus comprises six continuous openings of different diameters for engaging a variety of different gauged wires. The six continuous openings are formed from aligning a plurality of equally-sized half circle cutouts on opposing sides of a plurality of rectangular components that form a housing assembly. Each of the six continuous openings is penetrated by a cutting blade sandwiched between the plurality of rectangular components which are held in place by a securing element running through the plurality of rectangular components in a perpendicular orientation to the six continuous openings.
To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative of the various ways in which the principles disclosed herein can be practiced and all aspects and equivalents thereof are intended to be within the scope of the claimed subject matter. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter.
Referring initially to the drawings,
The housing assembly 102 comprises a plurality of rectangular components 104 each having a front face 106, a back face 108, and opposing sides 110. The plurality of rectangular components 104 are typically wood, metal, or plastic in construction, though it is contemplated that the plurality of rectangular components 104 may comprise a variety of materials as are known in the art without affecting the overall scope of the invention. To form the housing assembly 102, the plurality of rectangular components 104 are aligned in a generally parallel configuration and then held together with a securing element 124.
To align the plurality of rectangular components 104 in the generally parallel configuration, opposing sides 110 of the plurality of rectangular components 104 are abutted with each of the front faces 106 facing the same direction. In a preferred embodiment, there are four rectangular components 104 each approximately 2¼ inches in height, 2 inches wide, and 2% inches in depth, however any number of rectangular components 104 can be used. However, the plurality of rectangular components 104 may have varying dimensions as desired to accommodate larger or smaller wires and different work applications. For example, the plurality of rectangular components 104 could be twice as big or twice as small if desired.
The plurality of continuous openings 116 are formed from a plurality of equally-sized half circle cutouts 118 which are formed into the opposing sides 110 of the plurality of rectangular components 104. As the opposing sides 110 of the plurality of rectangular components 104 are abutted, the plurality of equally-sized half circle cutouts 118 are joined together to form the plurality of continuous openings 116. Each of the plurality of continuous openings 116 extend along the opposing sides 110 from the front face 106 to the back face 108 of the plurality of rectangular components 104 creating through holes in the wire stripping apparatus 100 that may each receive a wire or cable for stripping.
In a preferred embodiment, the wire stripping apparatus 100 comprises six continuous openings 116 of different diameters ranging from approximately 1/16 to ½ inches in diameter. This permits a user to strip up to six wires approximately between 0 and 22 in gauge simultaneously. However, this is not meant as a limitation as there may be more or less continuous openings of larger or smaller diameters as desired. In addition, the plurality of continuous openings 116 may have approximately identical diameters. Furthermore, while the plurality of continuous openings 116 are generally approximately circular in shape, they may be flatter in configuration to accommodate non-round wires and cables such as but not limited to Romex®, NM cable, control cables, instrument cables, and the like.
The housing element 102 further comprises a first end 112 and a second end 114. The first end 112 and the second end 114 each have one of the opposing sides containing none of the plurality of equally-sized half circle cutouts 118. Therefore, when assembled, two of the opposing sides 110 of the plurality of rectangular components 104 do not comprise any of the plurality of equally-sized half circle cutouts 118. This is desirable as it allows the housing element 102 to be generally rectangular in construction without indentations or cutouts for easier handling.
As illustrated in
In the preferred embodiment, the plurality of cutting blades 120 are positioned between at least three of the opposing sides 110 and are replaceable as the cutting edge 122 becomes dull. Therefore, there are two cutting blades 120 sandwiched between each of the abutted opposing sides 110 so that each of the plurality of continuous openings 116 has a single corresponding cutting blade 120. The plurality of cutting blades 120 are typically razor blades or utility blades, although any other similar thin cutting blade as is known in the art may be used as well.
The plurality of cutting blades 120 may be fixed or movable once positioned so that the depth of penetration of the cutting edges 122 into the plurality of continuous openings 116 may be adjusted as desired and held in place with the securing element 124. Typically, the cutting edges 122 penetrate into each of the plurality of continuous openings 116 between approximately 1/16 and ¼ inches. This is advantageous as the cutting edge 122 may then penetrate the outer insulating layer 12 of the wire 10 without cutting into the inner metal conductor 14. As illustrated in
