Description

Technical Field

[0002] Wired connections require continuous contact between the exposed portion of the wire and the electrical contacts. Therefore, it is important that once the wire is in its position relative to the contacts, the wire must be held or otherwise fixed in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Traditionally, when attaching a wire to a contact point, one of two methods is used. In the first method, the exposed end of the wire is connected to a conductive ring, which is then slid onto a bolt like a nut. The ring is an extension of the wire due to its connection to the exposed end. Because the bolt can be an electrical contact point (or an extension of an electrical contact point), the connection of the conductive ring to the bolt provides an electrical connection. Although the contact between the ring and the bolt is generally strong because the ring is relatively flush with the bolt, the connection between the exposed wire and the conductive ring may be weak or inconsistent without welding to hold the wire to the ring. Welded connections are labor intensive and require a certain degree of precision.

[0013] In the second method, the exposed wire directly contacts the live bolt. Typically, this is accomplished by feeding the exposed wire into a channel and then turning the bolt from the top of the channel down onto the wire so that the exposed wire is sandwiched between the channel wall and the live bolt. While this is a faster and easier connection than the welding of the first method, the pressure of the bolt on the wire often causes the wire to break or causes the individual strands of the wire to unravel, which often weakens the connection. Therefore, there is a need for an improved clamping system for holding the wire in place.

[0014] Referring now to the drawings, in which like reference numerals represent the same or similar features throughout the various views, Figure 1 is a perspective view of a system 10 for holding a wire in place. Figure 1-5 As shown, the system 10 includes a base 110, an insert 120, and a contact 130. The base 110 may include a front wall 101 having a wire hole 102, a rear wall 103 having a wire stop 104, a cavity 112, and first and second bolt holes 114a, 114b (collectively referred to as "bolt holes 114"). The base 110 can be formed of any material that is heat-resistant and / or non-conductive (e.g., plastic). The front wall 101 and the rear wall 103 can be substantially parallel, and the size of the gap between the front wall 101 and the rear wall 103 can be based on the specifications of the inserted wire, based on the preferred size of the contact point (e.g., Figure 3 ), or any other preferred dimensions that allow sufficient contact with the inserted wire to allow adequate conductivity.

[0015] The wire hole 102 may be located on the front wall 101 of the base 110 and may pass completely through the front wall 101. The shape and size of the wire hole 102 can be set to receive relatively large-sized wires for electronic devices or speaker applications, so that the diameter of the wire hole 102 can be 10mm (although holes of larger or smaller diameters are intended to be within the scope of the present disclosure). In addition, although the wire hole 102 is shown as a circular hole, the wire hole 102 can be any shape (e.g., square, oval, etc.) that can receive the wire and allow the wire to pass through the hole. The wire hole 102 can be formed in the base 110 using a drill bit of appropriate size by a drill press or similar tool, or can be formed during the initial molding of the base 110 (so that the base 110 is molded with the wire hole 102 already in its position).

[0016] The wire stop 104 may be a notch or groove in the rear wall 103 of the base 110. The wire stop 104 may have a similar size and shape as the wire hole 102, so that the wire hole 102 and the wire stop 104 may be machined by the same drill in the same press. In contrast to the wire hole 102, the wire stop 104 may not pass through the rear wall 103 of the base 110, so that the wire stop 104 includes a portion of the rear wall 103 as a stop or end point to prevent further insertion of the wire. The wire stop 104 may serve as a guide for inserting a certain amount of exposed wire into the base 110. As described below with reference to Figure 6-7 As discussed in detail, the insert 120 can press the wire into the cavity 112, which causes the wire to at least partially conform to the shape of the insert 120 and the cavity 112. Because this conforming shape can cause the wire to have a shorter horizontal distance than the insertion length of the unpressed wire, the insertion length of the unpressed wire can be greater than the distance between the front wall 101 and the back wall 103, so that when the wire is in its conforming shape, the wire can extend from the front wall 101 to the back wall 103. A larger insertion length can be achieved by the wire stopper 104, which allows the amount of inserted wire to be greater than the gap between the front wall 101 and the back wall 103. To this end, the depth of the wire stopper 104 (e.g., the amount of material of the back wall 103 that is machined away to form the wire stopper 104) can be the additional length required to allow the compliant wire to be long enough after being pressed by the insert 120. In some embodiments, wire stop 104 may be omitted, such that rear wall 103 may serve solely as an end point (or wire stop) for the inserted wires.

[0017] The gap between the front wall 101 and the rear wall 103 may include a cavity 112, such that the endpoints of the cavity 112 may be defined by the front wall 101 on the front side and the rear wall 103 on the rear side. Figure 2The cavity 112 may be substantially parabolic in shape, such that the lowest point of the cavity 112 may be a curved portion of the material and may be below the point where the cavity 112 intersects the front wall 101 and the rear wall 103 (e.g., relative to Figure 1 ). Figure 5 The cavity 112 is described in more detail.

[0018] like Figure 3 As shown, bolt hole 114 can be located in base 110 and can be positioned in and / or adjacent to the bottom of cavity 112 (e.g., relative to Figure 1 orientation), and may be sized and shaped to receive a first bolt 124a and a second bolt 124b (collectively, "bolts 124"). Although bolts 124 are shown and described as bolts, bolts 124 may be any similar fastener. Thus, bolt hole 114 may have a diameter substantially equal to the diameter of threaded portions 126a, 126b (collectively, "threaded portions 126") of bolt 124. In those embodiments where bolt 124 has different diameters, bolt hole 114 may have similarly corresponding different diameters. Bolt hole 114 may also be threaded so that bolt hole 114 may engage with corresponding threads on bolt 124 to move bolt 124 longitudinally (relative to bolt hole 114) when bolt 124 is rotated (e.g., turned, screwed, secured, etc.). Bolt hole 114 may be positioned on either side of wire contact 116 to correspond to bolts 124 positioned on either side of wire contact 116, as described below with respect to Figure 6-7 1. Although two bolt holes 114 are shown, a greater or lesser number of bolt holes 114 may be included depending on the number of bolts 124. For example, if only a single bolt 124 is used, there may be only a single bolt hole 114 in the base 110. In another example, if four bolts 124 are used, there may be four corresponding bolt holes 114 in the base. In this example, due to the number of bolts 124 and bolt holes 114, the size of each may be smaller to accommodate the increased number.

[0019] Insert 120 may include a wire surface 122 and first and second bolt channels 123a, 123b (collectively referred to as "bolt channels 123") corresponding to bolts 124. Wire surface 122 may be substantially parabolic in shape from a side view, such that the lowest point (relative to the Figure 1112) is at the center of the insert 120, and the wire surface 122 slopes upward from the center point toward the side of the insert 120. Therefore, the insert 120 can be substantially wedge-shaped. The wire surface 122 can have the same slope and substantially the same shape as the cavity 112, so that the wire surface 122 can be flush with the cavity 112 when it is engaged with the cavity 112 without any wire. As described in more detail below, the fact that the wire surface 122 matches the shape of the cavity 112 may be important for distributing the compressive force on the compressed wire to reduce the risk of wear.

[0020] The bolts 124 may each include a bolt cap 125a, 125b (collectively referred to as "bolt cap 125") and a threaded portion 126. The bolt cap 125 may have a larger diameter than the threaded portion 126 and may be configured to cooperate with a tool for rotating or turning the bolt 124. Although the bolt cap 125 is shown as being substantially circular and configured to be used with a hexagonal key, any shape (e.g., square, triangular, octagonal, etc.) and configuration for any tool (e.g., a screwdriver, an allen wrench, etc.) may be considered within the scope of the present disclosure. In addition, although the bolt cap 125 shown includes a groove for accommodating a hexagonal key, the bolt cap 125 may optionally include a protrusion for interacting with a tool (e.g., a wrench). As described above, the threaded portion 126 may be threaded to engage with the bolt hole 114 of the base 110. In some embodiments, each of the threaded portions 126a, 126b may have the same diameter so that the bolts 124a, 124b may be substantially the same bolts. In other embodiments, each of the threaded portions 126a, 126b can have a different diameter so that the bolts 124a, 124b can be substantially different bolts. Similarly, each bolt cap 125a, 125b can be substantially the same (e.g., the same size, configured for the same tool), or can be substantially different.

[0021] The bolt channel 123 may be substantially smooth so that the bolt 124 can rotate freely within the bolt channel 123. In some embodiments, the bolt channel 123 has a diameter substantially equal to the diameter of the threaded portion of the bolt 124 so that the threaded portion of the bolt 124 can be positioned within the bolt channel 123, but the bolt cap 125 may be too large. In these embodiments, the bolt cap 125 may engage with the top surface 120a of the insert 120. Figure 4 As shown, it is along Figure 2 In other embodiments, the bolt channel 123 may have a first portion 1231 and a second portion 1232, the first portion having a first diameter substantially equal to the diameter of the threaded portion of the bolt 124 (in Figure 4'a' in the figure), the second portion has a second diameter substantially equal to the diameter of the bolt cap 125 (in Figure 4 The first portion 1231 may be positioned longitudinally below the second portion 1232 (relative to Figure 4 120a). In some embodiments, the first and second portions 1231, 1232 of the bolt channels 123a, 123b may be arranged to be closer to the wire surface 122 and the second and second portions 1232, 123a, 123b may be closer to the top surface 120a. In these embodiments, the entire bolt 124 may be positioned within the bolt channel 123, wherein the threaded portion 126 is capable of passing through the entire bolt channel 123, and the bolt cap 125 may only be capable of passing through the second portion 1232. In this way, the bolt cap 125 may dock with the lip 1233 formed by the transition from the wider second portion 1232 to the narrower first portion 1231. In some embodiments, the first and second diameters and / or lengths of the first and second portions 1231, 1232 of the bolt channels 123a, 123b may be the same, so that the bolt channel 123 may be configured to receive the same bolt 124. In other embodiments, the first and second diameters and / or lengths of the first and second portions 1231, 1232 of the bolt channels 123a, 123b may be different, so that the bolt channel 123 may be configured to receive different bolts 124.

[0022] In either embodiment, the interaction between the bolt cap 125 and a corresponding surface (e.g., the top surface 120a or the lip 1233 within the bolt channel 123) works in conjunction with the bolt hole 114 to cause the bolt 124 to pull the insert 120 into the cavity 112 toward the base 110. In particular, since the bolt 124 can be fixed or rotated into the base 110 via the bolt hole 114, the bolt 124 can move longitudinally into the base 110. As the bolt 124 moves into the base 110, the distance between the bolt cap 125 and the base 110 can decrease because the bolt 124 functionally becomes shorter. Because the bolt cap 125 can engage with the insert 120, as described above, the bolt cap 125 can limit the upward (relative to the insertion) movement of the insert 120. Figure 1 ) moves, while the downward (relative to the Figure 1 102). The movement of the insert 120 may be limited by the base 110 (and more specifically, the cavity 112). Thus, as the distance between the bolt cap 125 and the base 110 decreases, the range of motion of the insert 120 decreases until the insert 120 may be snug or flush with the top of the cavity 112. Thus, by turning one or more bolts 124, the insert 120 may be forced toward the base 110 to, for example, compress the wire inserted into the cavity 112 in the wire hole 102.

[0023] The contacts 130 may extend laterally from the base 110 and may include external contacts 132. The external contacts 132 may be exposed or partially exposed live surfaces that may be electrically conductive via the wire contacts 116 ( Figure 3 ) is connected to the inserted wire. Each of the wire contact 116 and the external contact 132 can be formed of a conductive material (e.g., zinc, copper, aluminum, etc.). The external contact 132 can be further configured to receive a live contact from a separate wire or connector so that the contact 130 as a whole helps facilitate an electrical connection between a wire clamped in the system 10 and the separate wire. For example, the external contact 132 can be configured to cooperate and / or interact with a fuse holder, such as a fuse holder. Figure 8 The fuse holder 150. The contacts 130 and the base 110 may be integral so that current received by the base 110 (eg, from a wire inserted via the wire contact 116) may be transmitted to the contacts 130 (eg, to the external contacts 132).

[0024] Figure 6-7 is along Figure 4 6-6 of the system 10. Figure 6 The system 10 is shown in a disengaged state, Figure 7 The system 10 in the engaged state is shown. As shown, the system 10 may also include a wire 140 that can be inserted into the wire hole 102 as described above. The wire 140 can be any suitable metal strand that can conduct electrical signals, such as aluminum, copper, nickel or steel. The wire 140 can be formed by a single strand (e.g., a "solid wire") or multiple strands (e.g., a "twisted wire") that may be bundled or twisted together with an insulating layer. The electrical signal passing through the wire can represent an audio or video signal, so that the wire 140 can be used to transfer the audio or video signal from an input source to an output source. The wire 140 may include an insulating portion 142 and an exposed portion 144. The insulating portion 142 may include an insulating layer (e.g., plastic, rubber-like polymer, etc.) positioned around the inner strands or fibers of the wire 140. The exposed portion 144 may be a certain number of wires 140 stripped of insulation, so that the inner strands or fibers of the wire 140 can be exposed (e.g., the current passing through the wire can flow into or through any conductive surface that the exposed portion 144 contacts or contacts).

[0025] The wire 140 may be inserted into the wire hole 102. The wire 140 may be inserted a desired amount, which may be based on the end of the exposed portion 144 abutting the wire stopper 104. The insert 120 may then be inserted as described above by rotating or securing at least one bolt 124 into the bolt hole 114. Figure 6 As shown by the single arrow in FIG. 1 , the exposed portion 144 is pulled into the exposed portion 144 to press the exposed portion 144 generally into the cavity 112 and particularly onto the wire contact 116. Figure 7 As shown in the arrow extending from the wire surface 122 in the figure, the shape of the wire surface 122 can cause the insert 120 to apply pressure on the entire length of the wire surface 122 to distribute the compression applied to the wire 140 over the greater length of the wire 140. By distributing the compression in this way, the system 10 provides at least two obvious benefits. First, because the insert 120 has a larger surface area in contact with the wire 140, compared with the traditional method of using a single bolt to keep the frame wire in place, the system 10 provides a safer and more stable retention, which is mostly due to the increase of static friction caused by the increased surface area. Second, by dispersing the force on the wire 140 instead of concentrating the force on a single point (e.g., as a traditional single bolt), the system 10 reduces the risk of wear, which not only reduces the damage to the wire 140, but also improves the stability of the connection. In particular, if the wire 140 is a multi-strand wire, each strand of the wire 140 can carry an equal amount of current, and thus if the wire 140 becomes worn or otherwise damaged, one or more strands of the wire may extend (e.g., protrude) away from the wire contact 116, and any current carried by these strands may be ineffective in maintaining electrical contact.

[0026] Figure 8 1 is a perspective view of an exemplary embodiment of system 10. In this exemplary embodiment, the first system 10 and the second system 10' can be mounted on a plate 20. The plate 20 can be formed of a non-conductive material so that the plate does not interfere with or hinder any current flowing through the system 10, 10'. The first system 10 and the second system 10' can be identical and can be oriented to mirror each other so that the contacts 130, 130' can be close. As shown, the first system 10 shows the system 10 in a disengaged state, wherein the insert 120 is raised and separated from the base 110 to prepare to receive a wire (e.g., wire 140). The second system 10' shows the system 10 in an engaged state, wherein the insert 120' is fixed downwardly into the base 110' to compress the wire, if there is a wire. The fuse holder 150 can be located between the systems 10, 10', wherein the first end of the fuse holder 150 is operably connected to the first system 10, and the second end of the fuse holder 150 is operably connected to the second system 10'. Fuse holder 150 may be any suitable fuse holder capable of providing fuse protection on a wired electrical connection, such as a wired electrical connection formed by a first wire held by first system 10 and a second wire held by second system 10'.

[0027] Fig. 9900 is a flowchart showing an exemplary method 900 for clamping a wire in place using, for example, system 10. Method 900 may include, at box 910, providing a wire clamping system. The wire clamping system provided may be system 10, and may include a base (e.g., base 110) and an insert (e.g., insert 120). The base may include a first base wall (e.g., first wall 101) having an opening (e.g., wire hole 102), a second base wall (e.g., second wall 103), and a cavity (e.g., cavity 112) defined on either side by the first and second base walls. The cavity may include at least two holes (e.g., bolt holes 114) and internal contacts (e.g., wire contacts 116). The insert may include a first end (e.g., wire surface 122) configured to be flush with the cavity, a second end (e.g., top surface 120a), and at least two channels (e.g., wire channels 123).

[0028] The method 900 may also include inserting a fastener into each of the at least two channels in the insert at block 920. The fastener may be a bolt (eg, bolt 124), a screw, a pin, or any similar elongated member having a securing capability.

[0029] Method 900 can also include, at frame 930, positioning the wire in the cavity via the opening in the first pedestal wall.Wire (e.g., wire 140) can be any wire that carries current.Before positioning the wire, at least a portion of the wire (e.g., insulating material around the twisted wire of the wire is removed), and the part stripped of the insulating material can be positioned in the cavity.By stripping the wire, the exposed strand can directly contact the internal contact in the cavity.In those embodiments where the second pedestal wall includes a recess (e.g., wire stopper 104), the wire can be inserted until the wire abuts the recess.

[0030] The method 900 may also include, at block 940, rotating a fastener in each of the at least two channels. The fastener may engage a hole in the cavity, which may be threaded, such that rotating the fastener causes the fastener to move or be pulled into the hole. This movement of the fastener causes the insert to move toward the hole again, which presses the wire against the internal contact to energize at least a portion of the clamping system.

[0031] The systems and methods herein provide many benefits over conventional wire clamps. For example, the horizontal length of the wedge-shaped insert 120 enables the system 10 to secure wires 140 of various gauges, particularly large gauge wires that may be problematic with single-bolt clamps. Additionally, as described herein, the shape of the insert 120 distributes the compressive force over a greater surface of the wire 140 than from a single point of force applied with a single-bolt clamp, which not only improves the strength of the clamp, but also reduces the risk of damage to the wire and improves the consistency of the connection.

[0032] In some embodiments, the wire clamping system includes: a base including a first base wall; a second base wall; and a cavity defined by the first base wall and the second base wall, the cavity having a lower portion. The system also includes an insert configured to fit within the cavity, the insert including a first end formed to be substantially flush with the cavity; a second end opposite the first end; and at least two channels extending therethrough. The system also includes at least two bolts and at least two holes, the at least two bolts being configured to be received by the second end of the insert, the at least two holes being positioned in the lower portion of the cavity. Securing the at least two bolts to the at least two holes causes the first end of the insert to move toward the lower portion of the cavity.

[0033] In some of these embodiments, the first base wall includes an opening shaped to receive a wire for passing through it and placed in the cavity. In other embodiments of these embodiments, the second base wall includes a recess shaped to receive the wire and prevent the wire from further moving through the opening in the first base wall. In some of these embodiments, the first end is substantially wedge-shaped. In other embodiments of these embodiments, the first end includes a parabolic side profile, wherein the relative center of the first end is the farthest front extension of the first end.

[0034] In some of these embodiments, the at least two bolts each include a threaded portion; each of the at least two holes is threaded to match the threaded portion of the at least two bolts; and the at least two passages of the insert are unthreaded to allow rotation of the at least two bolts. In some of these embodiments, the at least two bolts each also include a cap, the threaded portion of at least one of the at least two bolts has a first diameter, and the cap of at least one of the at least two bolts has a second diameter greater than the first diameter, at least one of the at least two passages includes a first portion having a first diameter substantially equal to the first diameter, a second portion having a second diameter substantially equal to the second diameter, and a lip defined by a transition from the first portion to the second portion, and when each of the at least two bolts is received by each of the at least two passages, the cap abuts the lip. In some of these embodiments, when the at least two bolts are secured to the at least two holes, the abutting cap applies a force to the lip, and the applied force causes the first end of the insert to move toward a lower portion of the cavity through an interface between the cap and the lip.

[0035] In some of these embodiments, the system further includes an external contact electrically connected to the contact located in the cavity. In some of these embodiments, the external contact is configured to receive a fuse holder.

[0036] In some embodiments, a wire clamping system includes a cavity having a lower portion; and an insert having an end and two passages therethrough, the end being shaped to fit within the cavity. Two holes and an internal contact may be positioned adjacent to the lower portion of the cavity. Each of the two passages is configured to receive a fastener, each of the two holes is configured to engage with the fastener, and rotating the fastener causes the insert to move within the cavity.

[0037] In some of these embodiments, the insert end is substantially wedge-shaped. In others of these embodiments, the insert end comprises a parabolic side profile, wherein a relative center of the first end is a farthest forward extension of the first end.

[0038] In some of these embodiments, the fastener includes a threaded portion; the two cavity holes are threaded to mate with the threaded portion; and the two passages of the insert are unthreaded, allowing the fastener to rotate.

[0039] In some of these embodiments, the fastener further comprises a cap, the threaded portion having a first diameter, the cap having a second diameter greater than the first diameter, the two channels each comprising a first portion having a diameter substantially equal to the first diameter of the fastener, a second portion having a diameter substantially equal to the second diameter of the fastener, and a lip defined by a transition from the first portion to the second portion of the channel, and the cap abuts the lip when each fastener is received by each of the two channels. In some of these embodiments, the abutting cap applies a force to the lip when the fastener is rotated, and the applied force causes the insert to move toward a lower portion of the cavity.
