DETAILED DESCRIPTION
The present disclosure is generally directed toward electrical connectors that can be used, for example, for electrically connecting wires. The electrical connectors generally include members (e.g., arms, etc.) that are coupled together (e.g., pivotally coupled together, etc.) to allow the members to move relative to each other. For example, the members may be moveable relative to each other between first positions where wires can be inserted into the electrical connectors to be electrically connected and second positions where the electrical connectors operate to bend the connected wires.
In one aspect, the members of the electrical connectors include receptacles configured to receive the wires into the electrical connectors (e.g., when the electrical connectors are in the first positions, etc.) to facilitate electrical connection of the wires. In some embodiments, the electrical connectors include metallic coils positioned within the receptacles to make the electrical connections between the wires. In some embodiments, members of the electrical connectors also, or alternatively, include openings configured to allow the wires to be inserted through the openings and into the receptacles (e.g., when the electrical connectors are in the first positions, etc.). And, upon movement of the members (e.g., from the first positions to the second positions, etc.), the wires in the openings are then bent by the members.
In another aspect, the electrical connectors include sleeves configured to hold insulating material to help coat the wires when the wires are inserted into the electrical connectors. For example, the sleeves may be positioned adjacent the receptacles of the electrical connectors to help coat the wires when the wires are inserted into the receptacles and, for example, prior to receiving the wires in the metallic coils.
It should be appreciated that the electrical connectors of the present disclosure can include one or more of the above described aspects in any desired combination, and can further include any of the other features described herein as desired. With that said, example embodiments of the electrical connectors will now be described more fully with reference to the accompanying drawings.
FIG. 1-10 illustrate an electrical connector 100 according to an example embodiment of the present disclosure. The illustrated electrical connector 100 can be used to make desired electrical connections between wires (e.g., bare ends of wires, etc., not shown) inserted into the electrical connector 100. And, the electrical connector 100 is configured (e.g., sized, shaped, constructed, etc.) to help hold the connected wires in the electrical connector 100 (e.g., against inadvertent, unwanted, etc. removal, etc.). In addition, the electrical connector 100 is configured to inhibit ingress of moisture into the electrical connector 100 where the wires are connected. As such, the electrical connector 100 can provide a durable, reliable, etc. connection and may be used in a wide variety of environments (e.g., indoor environments, outdoor environments, underground environments, etc.), including those that are moist, damp, etc.
As shown in FIGS. 1 and 2, the illustrated electrical connector 100 generally includes a first member 102 and a second member 104 (separate from the first member 102) pivotally coupled together. As such, the first member 102 and the second member 104 can pivot relative to each other between a first, receiving position (FIG. 1) in which the first member 102 is oriented relative to the second member 104 at an angle of about ninety degrees, and a second, connecting position (FIG. 2) in which the first member 102 is folded over the second member 104 (with the second member 104 generally nested within an arm portion 106 of the first member 102). Such movement can be facilitated by a user grasping the first and second members 102, 104 and pivoting them as desired. Additional views of the electrical connector 100 in the receiving position and in the connecting position are shown in U.S. Provisional Patent Application No. 61/555,333, which (as stated above) is incorporated herein by reference in its entirety. With that said, in other example embodiments electrical connectors may include first and second members oriented relative to each other at angles greater than about ninety degrees or at angles less than about ninety degrees when in receiving positions.
With additional reference to FIGS. 3-6, the first member 102 of the electrical connector 100 generally includes an opening 112 and a shoulder 114 located adjacent the opening 112. The opening 112 is configured to allow wires (not shown) to be inserted into the electrical connector 100 through the first member 102 (via the opening 112) when the first and second members 102, 104 are in the receiving position. Specifically, the opening 112 allows the wires to be inserted through the first member 102 and into the second member 104 of the electrical connector 100 (as will be discussed in more detail below). Then, when the electrical connector 100 is moved to the connecting position, the shoulder 114 of the first member 102 is configured to engage the inserted wires and bend them, as desired. Here (when the electrical connector 100 is in the connecting position), a channel 116 defined in the second member 104 generally aligns with the opening 112 in the first member 102 (see, e.g., FIG. 6, etc.) and accommodates the bent wires in the electrical connector 100. This may or may not help hold the connected wires in the electrical connector 100 and may or may not provide strain relief to the wires. For example, it is contemplated that the bent wires may still be moved, as needed (e.g., to reorient the wires, reposition the wires, etc.), relative to the electrical connector within the opening 112 of the first member 102 and/or within the channel 116 of the second member 104. As such, in this contemplation, the bent wires may not be secured within the electrical connector 100 between the first and second members 104 at the opening 112 and/or the channel 116.
With reference now to FIGS. 6 and 7, the second member 104 of the electrical connector 100 includes a receptacle 122 configured to receive the wires to be electrically connected, and a metallic coil 124 (separate from the second member 104) positioned within the receptacle 122 to make the electrical connection between the wires. In particular, the metallic coil 124 operates to thread onto end portions (e.g., bare end portions, stripped end portions, etc.) of the wires and weave, wrap, tie, twist, etc. the wires together to connect them. For example, the end portions of the wires can be positioned within the metallic coil 124 in the receptacle 122 (through the opening 112 of the first member 102), and the first and second members 102, 104 can then be together turned to thread the metallic coil 124 onto the end portions of the wires (and electrically connect the wires). The metallic coil 124 may be configured to retain the wires in the electrical connector 100 after electrically connecting the wires. To help facilitate this operation, an outer portion of the receptacle 122 is contoured to help a user grasp the second member 104 and turn it as desired. In addition, the orientation of the first and second members 102, 104 when in the receiving position (e.g., with the first and second members 102, 104 oriented at bout ninety degrees relative to each other, etc.) also helps the user grasp the first and second members 102, 104 and turn them as desired. The first and/or second members 102, 104 may include other suitable contouring, for example, to help a user grasp them, within the scope of the present disclosure.
In the illustrated embodiment, the metallic coil 124 is inserted into the receptacle 122 of the second member 104 of the electrical connector 100 and secured therein. As such, the metallic coil 124 can turn with the second member 104 relative to wires inserted into the receptacle 122. For example, the metallic coil 124 may be molded directly into the receptacle 122 of the second member 104 (e.g., the receptacle 122 may be molded over, around, etc. the metallic coil 124, etc.). Or, the metallic coil 124 may be secured in the receptacle 122 of the second member 104, for example, adhesive, solder, suitable mechanical fasteners, etc.
With additional reference to FIG. 8, a sleeve 126 is positioned generally above the metallic coil 124 of the electrical connector 100, and adjacent the receptacle 122 of the first member 102 of the electrical connector 100. The sleeve 126 is configured to hold insulating material 128 therein to help coat the wires (e.g., the bare end portions of the wires, etc.) when the wires are inserted into the electrical connector 100 through the opening 112 of the of the first member 102 (and prior to inserting the wires into the metallic coil 124 for electrical connection). In particular, upper and lower end portions of the sleeve 126 are open such that the wires can be inserted through the sleeve 126 (and through the insulting material therein), and then into the metallic coil 124 in the receptacle 122 of the first member 102. This allows the insulating material to initially coat the wires and effectively surround the bare end portions of the individual wires before they are inserted into the metallic coil 124 for connection. As such, the connected portions of the wires will then be coated with the insulating material. With that said, any suitable insulating material may be used with the electrical connector 100. For example, the insulating material may include a moisture resistant encapsulate or gel, and may be a viscous or non-viscous material and/or include a hardening or non-hardening epoxy or potting compound. In addition, the insulating material may have a sufficient viscosity so that it will not flow out of the sleeve 126 (e.g., out of the electrical connector 100, into the metallic coil 124, etc.), but at the same time will move with the wires into the metallic coil 124 and flow around them as they are connected (e.g., to provide a waterproof seal around the connected wires, etc.).
With reference now to FIGS. 9 and 10, the first member 102 of the electrical connector 100 also includes a side portion 132 with an opening 134 therein configured to receive a hinge pin 136 formed in a corresponding side portion 138 of the second member 104. The hinge pin 136 operates to couple the separate first and second members 102, 104 together. In particular, when received in the opening 134 of the first member 102, the hinge pin 136 facilitates the pivoting movement of the first and second members 102, 104 between the receiving position and the connecting position (FIGS. 1 and 2). In the illustrated embodiment, the hinge pin 136 is formed as part of the side portion 138 of the second member 104 and is configured to fit within the opening 134 of the side portion 132 of the first member 102 to allow the pivoting movement. In other example embodiments, however, electrical connectors may include separate first and second members coupled together by other suitable means. For example, second members may include hinge pins configured to fit within openings of first members. Or, separate hinge pins may be used and positioned through openings of first and second members to pivotally couple them together.
The second member 104 of the electrical connector 100 also includes a side portion 140 located opposite the side portion 138. The side portion 140 is configured to fit within an opening 142 of the first member 104 when the first and second portions 102, 104 are coupled together. The side portions 138, 140 of the second member 104 help support, balance, stabilize, etc. the first member 102 when coupled to the second member 104. The side portions 138, 140 also provide barriers along the sides of the electrical connector 100 and thus can help inhibit ingress of unwanted debris, etc. into the electrical connector 100.
The first and second members 102, 104 of the electrical connector 100 are also configured to latch together, as desired, when in the connecting position. For example, the first member 102 includes a pair of arms 146, 148 configured to hook over a corresponding pair of tabs 150, 152 of the second member 104. As such, when the first and second members 102, 104 move to the connecting position, the arms 146, 148 can then also be moved over the tabs 150, 152 (e.g., in a snap-fit fashion, etc.) to thereby help hold the first and second members 102, 104 together (e.g., against unwanted, undesired, unintentional movement toward the receiving position, etc.). While not required, this may, in turn, help hold the connected wires in their bent configuration. In addition, while the bent wires may still be moveable relative to the first and second members 102, 104 (within the opening 112 and the channel 116), this may also help inhibit complete unwanted, undesired, unintentional removal of the wires from the electrical connector 100.
An example use of the electrical connector 100 to connect wires will now be described. The first and second members 102, 104 of the electrical connector 100 are initially moved to the receiving position (FIG. 1). Desired wires are then inserted into the electrical connector 100 through the opening 112 in the first member 102 and into the receptacle 122 of the second member 104. The insulating material in the sleeve 126 coats the bare ends of the wires as they move into and through the sleeve 126, and then into the metallic coil 124, for example, to provide a waterproof seal around the bare end portions of the wires. The first and second members 102, 104 are next turned to thread the metallic coil 124 onto the wires to thereby electrically connect them. The first and second members 102, 104 are then moved to the connecting position (FIG. 2). In particular, the first member 102 is pivoted relative to the second member 104, during which the shoulder 114 of the first member 102 bends the connected wires.
FIGS. 11 and 12 illustrate an electrical connector 200 according to another example embodiment of the present disclosure. The electrical connector 200 is substantially similar to the electrical connector 100 previously described and illustrated in FIGS. 1-10. The electrical connector 200 generally includes a first member 202 and a second member 204 pivotally coupled together via a hinge pin 236. The first member 202 includes an opening 212 and a shoulder 214 located adjacent the opening 212. The opening 212 is configured to allow wires to be inserted into the electrical connector 200 through the opening 212, and the shoulder 214 is configured to engage the wires and bend them, as desired, when the first and second members 202, 204 are moved from a receiving position to a connecting position. In addition, the second member 204 includes a receptacle 222 configured to receive the wires to be electrically connected, and a metallic coil 224 positioned within the receptacle 222 to make the electrical connection between the wires. A sleeve 226 is positioned within the receptacle 222 of the first member 202, at a location generally above the metallic coil 224. The sleeve 226 is configured to hold insulating material (not shown) therein to help coat the wires (e.g., the end portions of the wires, etc.) when the wires are inserted into the electrical connector 200 for electrical connection. Further, the first and second members 202, 204 are configured to latch together, as desired, when in the connecting position to help hold the connected wires therein. The first member 202 includes a pair of arms 246, 248 configured to hook over a corresponding pair of tabs 250, 252 of the second member 204.
FIGS. 13 and 14 illustrate an electrical connector 300 according to another example embodiment of the present disclosure. The electrical connector 300 is again substantially similar to the electrical connector 100 previously described and illustrated in FIGS. 1-10. The electrical connector 300 generally includes a first member 302 and a second member 304 pivotally coupled together via a hinge pin 336. The first member 302 includes an opening 312 and a shoulder 314 located adjacent the opening 312. The opening 312 is configured to allow wires to be inserted into the electrical connector 300 through the opening 312, and the shoulder 314 is configured to engage the wires and bend them, as desired, when the first and second members 302, 304 are moved from a receiving position to a connecting position. In addition, the second member 304 includes a receptacle 322 configured to receive the wires to be electrically connected, and a metallic coil 324 positioned within the receptacle 322 to make the electrical connection between the wires. A sleeve 326 is positioned within the receptacle 322 of the first member 302, at a location generally over the metallic coil 324. The sleeve 326 is configured to hold insulating material (not shown) therein to help coat the wires (e.g., the end portions of the wires, etc.) when the wires are inserted into the electrical connector 300 for electrical connection. Further, the sleeve 326 has a recessed portion 360 formed therein and configured to generally align with the opening 312 in the first member 302 when the electrical connector 300 is in the connecting position.
