Definitions
- the present invention is directed to a wire connecting method for providing connection of one or more wires to a connector.
- the present invention is directed to a wire connecting method that provides poke-in connections to connectors that substantially resist unintentional disengagement from pulling and/or twisting of the wires.
- Wire terminals are well known in the connector industry. Typically, the terminals include a pin and mating socket, together with a conductor connecting portion. In the event that the terminals are connected to wires, the terminals include a wire connecting section.
- One such form of wire connecting section is the wire crimp, where the wire is stripped and placed in a terminal end, and then crimped in place where the metal deforms about the conductor to form the electrical connection.
- electrical wires are attached to plug-in connectors by inserting an end of the wire into an opening of the connector where the wire is engaged by a force to hold or lock the wire into place.
- a poke-in connector wherein an insulated wire, particularly a wire having a portion of the insulation removed, is inserted into a connector and the connector engages the wire therein.
- This engagement of the wire may be by a lance, tab, spring or other compressive mechanism within the connector.
- the wire may become disconnected from the connector resulting in a loss of electrical connection.
- the disconnected wire may be electrically hot, particularly during installation or maintenance.
- the disconnection results from forces resulting from pulling and/or twisting of the wires in a manner that exceeds the force retaining the wires within the connector, allowing the wire to deform and slip from the connector.
- the twisting or rotation of the wire significantly reduces the amount of force required to disengage the wire from the connector.
- the contact engagement effectively cuts helical threads into the conductor during rotation, resulting in an unscrewing of the conductor from the connector.
- Patent US 3836938 A prior art connector is disclosed in patent US 3836938 .
- the connector includes a socket with a body on opposite sides of which supporting means are provided which are connected by a pair of through rivets, screws or bolts which act to hold the supporting means to the socket body and clamp cables extending therefrom between clamping flange extensions of the supporting means so as to prevent the cables extending from the socket body from being accidentally pulled out of sockets located in the socket body.
- Patent US 4868905 discloses an electric motor body with first and second exterior slots arranged at right angles to each other and through which a power lead can be led.
- Patent US 3909099 provides an electrical connector as recited in the preamble of claim 1.
- a method of connecting a wire to an electrical connector comprising the steps of: (i) providing a connector having a connector housing having at least one opening configured to receive the wire along an opening center axis and a wire retention member with a wire guide, wherein an arm extends from the wire retention member to form a slot between said arm and the connector housing, said arm further includes the wire guide and an arm slot, which are configured to permit insertion of the wire through said wire guide and into said opening; (ii) inserting the wire through the wire guide into the opening; and (iii) removing the wire from the wire guide through the arm slot in the wire guide, to provide a joggle or bend in the wire to provide resistance to pulling and rotation of the wire.
- the present invention is directed to a wire retaining system that substantially prevents unintentional disengagement of wires inserted into connectors due to pulling and/or twisting or rotating the wires.
- the present invention permits a poke-in connection of insulated wires reducing or eliminating wires unintentionally disengaging from the connector.
- One aspect of the present invention includes a wire retaining connector for providing pulling and/or twisting resistance having a connector body having at least one opening configured to receive a wire.
- the wire includes a partially exposed conductor and insulation.
- the connector body also includes a wire retention member having at least one surface onto which a wire may be engaged. The wire retention member provides sufficient retention of the wire to resist rotation and disconnection of the wire from the connector body.
- a wire retention connector system for providing pulling and/or twisting resistance having a first connector body and a second connector body each, independently, having at least one opening configured to receive a wire.
- the wire includes a partially exposed conductor and insulation.
- the connector body further includes a wire retention member having at least one surface onto which a wire may be engaged.
- the wire retention member provides sufficient retention of the wire to resist rotation and disconnection of the wire from the connector body.
- the first connector body and the second connector body include features that disengagably connect the first connector body to the second connector body.
- a wire retaining connector for providing pulling and/or twisting resistance having a wire terminal configured to receive a wire and at least a portion of insulation surrounding a conductive portion of the wire along an axis.
- the wire terminal includes a blade arranged perpendicular to the axis. The blade extends a distance inward from a surface of the wire terminal sufficient to contact the insulation. The blade forms a channel in the insulation during insertion of the wire into the terminal. The channel sufficiently engages the blade to substantially resist rotation between the wire and the wire terminal.
- the present invention provides a method for providing a connector with resistance to wire disconnection.
- the method includes providing a connector having a connector body having at least one opening configured to receive a wire.
- the wire includes a partially exposed conductor and insulation.
- the connector body further includes a wire retention member having at least one surface onto which a wire may be engaged.
- the wire retention member provides sufficient retention of the wire to resist disconnection of the wire from the connector body.
- the wire is inserted into the connector body in a direction substantially along an axis. At least a portion of the wire is oriented at an angle to the axis wherein the orienting further includes positioning the wire adjacent to at least one surface of the wire retention member.
- Still another aspect of the present invention includes a method for providing a connector with resistance to wire disconnection.
- the method includes providing a connector having a connector body having a wire terminal configured to receive a wire and at least a portion of insulation surrounding a conductive portion of the wire along an axis.
- the wire terminal has a blade arranged perpendicular to the axis. The blade extends a distance inward from a surface of the wire terminal sufficient to contact the insulation.
- the wire is inserted into the connector body along an axis in a direction substantially along an axis to a sufficient depth to engage the wire terminal.
- a channel is formed in the insulation during insertion of the wire into the terminal by the blade. The channel sufficiently engages the blade to resist axial rotational movement between the wire and the wire terminal.
- An advantage of an embodiment of the present invention is that a poke-in connection may be utilized wherein special tools and/or crimping are not required.
- Another advantage of an embodiment of the present invention is that the wires are sufficiently engaged with the connector to substantially prevent the unintentional disengagement of the wires from the connector.
- Still another advantage of an embodiment of the present invention is that the connectors are easily manufactured.
- Still another advantage of an embodiment of the present invention is that the connectors resist wire twisting and inadvertent unscrewing of the wires from the connector, wherein the rotation of the wires is minimized or eliminated, increasing the force required to disengage the wires from the connector.
- Still another advantage of an embodiment of the present invention is that the connectors provide improved wire dress and/or wire management.
- the present invention includes an embodiment of a wire retaining system for providing resistance against unintentional disengagement of wires inserted therein.
- the present invention allows the use of poke-in connections wherein wires may be engaged with the connectors without the use of crimping or special tools.
- FIGs. 1-4 show a wire retaining system having an wire terminal 100 that is configured to be locked into connector housing 400 (see FIG. 4 ) and to lockingly receive electrical wire 105.
- Electrical wire 105 includes conductor 107 and insulation 109.
- the configuration of wire 105 may be any configuration of wire that includes an insulated conductive portion. Suitable wires 105 include, but are not limited to, 18-gauge solid-core copper wire.
- Wire terminal 100 includes a terminal body 103, a locking portion or member 111, defining a locking shoulder 113 for engaging a surface of a connector housing 400 (see, e.g., FIG. 4 ) to securely retain wire terminal 100 within connector housing 400.
- terminal body 103 further includes a contact gripping element 201 arranged extending into an aperture 205 within terminal body 103.
- Terminal body 103 further includes a stop 207 in electrical communication with terminal body 103 that provides a surface onto which a conductor 107 may abut to establish a maximum insertion of wire 105 (see, e.g., FIG. 3 ) inside terminal body 103.
- Stop 207 may be formed from terminal body 103 or may be attached to the terminal body 103.
- the contact gripping element 201 may be cut or stamped out from terminal body 103, but as shown, is stamped from a blank of material from which it is formed. Alternatively, contact gripping element 201 may be separately provided and secured to terminal body 103.
- wire terminal 100 is of unitary construction.
- Contact gripping element 201 may be resiliently biased into the form of, for example, a leaf spring or beam structure.
- the contact gripping element 201 defines a wire trap for contacting an exposed conductor of an insulated wire or a conductor of an uninsulated wire or an electrically conductive contact having a similar cross-section.
- the wire terminal 100 further includes a blade 117 extending inwardly from the terminal body 103 into aperture 205 toward a terminal center axis 203.
- conductor 107 of wire 105 is installed in wire terminal 100 by directing conductor 107 along terminal center axis 203 post blade 117 toward end 303 until conductor 107 abuts stop 207.
- Stop 207 is shown as a tab that is biased inwardly into aperture 205. However, stop 207 may also include a region of reduced cross-sectional area to provide a surface to abut conductor 107 when fully inserted inside aperture 205.
- blade 117 preferably extends toward terminal center axis 203 perpendicularly to terminal center axis 203.
- the extension of the blade 117 toward terminal center axis 203 is preferably such that the blade 117 contacts the insulation 109 of wire 105 inserted in terminal 100. This contact is such that the blade 117 slices or shears a groove or channel 301 (see FIGs. 3-4 ) in the insulation 109 during insertion of the wire 105 into the terminal with the channel 301 providing an engagement with the wire 105 to substantially prevent axial rotation between the wire 105 and the wire terminal about terminal center axis 203.
- the blade 117 may also include a tapered edge (not shown) arranged parallel to terminal center axis 203 to reduce the force associated with inserting wire 105 and forming channel 301.
- the position of blade 117 may be any circumferential position on terminal body 103 that permits extension of blade 117 toward wire 105. That is, blade 117 may extend into aperture 205, but not necessarily aligning with terminal center axis 203.
- the extension of blade 117 may provide a channel 301 in the insulation 109, the conductor 107 or any combination thereof.
- the blade 117 may be incorporated into contact gripping element 201 wherein the channel 301 is formed on the conductor 107.
- a plurality of blades 117 may be utilized to further resist wire rotation.
- FIG. 4 shows a cross-sectional view of a connector housing illustrating a wire terminal 100 arranged within the connector housing 400, with a portion of the connector housing 400 removed.
- Locking member 111 at the locking shoulder 113 engages surface of the connector housing 400 to substantially prevent disengagement of the wire terminal 100 from the connector housing 400.
- Connector housing 400 may be configured in any manner that mates a second connector housing (see, e.g., FIG. 13 ), wherein each of the connector housing 400 and wire terminal 100 receives and engages a conductor 107 of a wire 105 for electrical connection of wires 105 to the second connector.
- Connector housing 400 is preferably fabricated from a non-electrically conductive material, such as, for example, conventional engineering grade thermoplastic. As shown in FIG.
- the connector housing 400 and the wire terminal 100 are configured as a female connection via aperture 205 at end 303 for receiving a male plug. While wire terminal 100 is shown as including a female connection at end 303, the wire terminal 100 may include a male plug at end 303 or any other structure that permits electrical communication between engaged connector housings.
- the connector housings 400 may be engaged in any suitable manner, including but not limited to, disenagable latches 401 that are disengagable by depressing latch arms 403.
- Mating connector housings may include latch features 1301 (see, e.g., FIG. 13 ) that engage latches 401 and substantially prevent disengagement of the connector housings 400.
- connector housing 400 includes opening 405 that may have mating geometries that permit orientation of mating plugs only in desired configurations. Engagement of connector housings 400 and their corresponding wire terminals 100 permits safe and easy electrical connection/disconnection of wires 105 without the necessity of crimping, special tools or equipment. As shown in FIG. 4 , a plurality of wires 105 may be inserted into connector housing 400, wherein the arrangements of corresponding wire terminals 100 may be the same or different than the arrangement shown in FIG. 4 .
- the engagement of blade 117 with rotation resistance is achieved by formation of channel 301, wherein channel 301 has sufficient depth into insulation 109 and/or conductor 107 to provide substantial resistance to rotation about terminal center axis 203. While it is preferable to provide channel 301 into the insulation 109 only, the channel 301 may also be formed into conductor 107.
- This rotational resistance allows the wire 105 engaged or trapped by contact gripping element 201 to remain engaged and substantially prevents unintentional disengagement of wire 105 due to rotation and pulling of wire 105 about terminal center axis 203. Additional blades 117 provide additional rotational resistance, but also increase the amount of force required to insert wire 105.
- FIG. 5 shows a cross-sectional view of another connector with a portion of the connector housing 400 removed, including a wire terminal 100 according to an embodiment of the present invention arranged within connector housing 400.
- the embodiment shown in FIG. 5 includes substantially the same arrangement of connector housing 400 and wire terminal 100 substantially as shown and described in FIG. 4 .
- the wire terminal 100 in the embodiment shown in FIG. 5 may or may not include blade 117.
- connector housing 400 further includes an angle channel 501 configured to conform wire 105 (i.e., bend) in a plurality of axes, including axes different than terminal center axis 203. During insertion of conductor 107 into connector housing 400, the wire is directed along angle channel 501 in a direction at an angle to terminal center axis 203.
- the conductor 107 is directed along terminal center axis 203.
- the wire 105 and conductor 107 are configured into at least a first wire orientation section 503 which is oriented substantially parallel to and/or coincident with about the terminal center axis 203, a second wire orientation section 505 which is oriented substantially parallel to and/or coincident with about an angle channel axis 506 and a third wire orientation section 507, which is oriented substantially parallel to and/or coincident with about a front opening axis 508.
- the orientation of the inserted wire 105 may include greater than three axes and may include curved, rounded or twisted orientations along the angle channel 501 or exterior to the connector housing 400.
- a plurality of wires 105 may be inserted into connector housing 400, wherein the arrangements of corresponding wire terminals 100 and the presence and arrangement of angle channel 501 may be the same or different than the arrangement shown in FIG. 5 .
- angle channel 501 may include multiple orientations for directing wire 105 into a plurality of directions.
- the angle channel 501 may be oriented at any angle or direction that provides an angle to terminal center axis 203. This embodiment of the present invention permits the easy engagement of wire 105 while reducing or eliminating undesired/unintentional disengagement of wire 105 from the wire terminal 100 and/or the connector housing 400.
- FIG. 6 illustrates a wire retaining system, including a connector housing 400 having openings 600 configured to receive wires 105 (not shown in FIG. 6 ).
- a connector housing 400 having openings 600 configured to receive wires 105 (not shown in FIG. 6 ).
- at least one rib 601 is configured to receive wire 105.
- ribs 601 are configured to engage the insulation 109 of wire 105.
- the ribs 601 may be of certain construction with the connector housing 400 or may be attached to opening 600.
- the ribs 601 are preferably a non-conductive material of sufficient rigidity and having a geometry that grips the insulation 109 and resists or prevents rotation of wire 105 when wire 105 is inserted rotationally about opening center axis 603.
- a conductive material such as a metal may be utilized in the connector housing 400 or as insert thereto, forming ribs 601 for gripping wire 105.
- the ribs 601 may be oriented at an angle to opening center axis 603 or perpendicular to opening center axis 603. In other words, ribs 601 may or may not radially extend in alignment with opening center axis 603.
- ribs 601 preferably sufficiently engage insulation 109 that the resistance to undesired/unintentional disengagement parallel to opening center axis 603 is likewise increased. As shown, ribs 601 are arranged substantially parallel to the opening center axis 603 of opening 600.
- FIG. 7 illustrates a wire retaining system, including a connector housing 400 having openings 600 configured to receive wires 105 (not shown in FIG. 7 ). Openings 600 may include ribs 601, as shown and described above with respect to FIG. 5 , and/or the connector housing 400 may include wire terminal 100 structures, as described above with respect to FIGs. 1-5 .
- the connector housing 400 further includes a segmenting slot 700 extending through both openings 600 and through the connector housing 400.

Description
- The present invention is directed to a wire connecting method for providing connection of one or more wires to a connector. In particular, the present invention is directed to a wire connecting method that provides poke-in connections to connectors that substantially resist unintentional disengagement from pulling and/or twisting of the wires.
- Wire terminals are well known in the connector industry. Typically, the terminals include a pin and mating socket, together with a conductor connecting portion. In the event that the terminals are connected to wires, the terminals include a wire connecting section. One such form of wire connecting section is the wire crimp, where the wire is stripped and placed in a terminal end, and then crimped in place where the metal deforms about the conductor to form the electrical connection.
- It is desirable in certain applications to not require a crimped connection. Typically, this is in the situation where the wires are stripped on site, and where crimping tools are not readily available. An example of such a situation would be in the lighting industry where overhead lights are installed, and it is easier for the installer to not require a crimped connection.
- Currently, electrical wires are attached to plug-in connectors by inserting an end of the wire into an opening of the connector where the wire is engaged by a force to hold or lock the wire into place. Particularly desirable is a poke-in connector, wherein an insulated wire, particularly a wire having a portion of the insulation removed, is inserted into a connector and the connector engages the wire therein. This engagement of the wire may be by a lance, tab, spring or other compressive mechanism within the connector.
- If the wire is pulled and/or twisted while engaged with the connector, the wire may become disconnected from the connector resulting in a loss of electrical connection. In addition, the disconnected wire may be electrically hot, particularly during installation or maintenance. The disconnection results from forces resulting from pulling and/or twisting of the wires in a manner that exceeds the force retaining the wires within the connector, allowing the wire to deform and slip from the connector. In particular, the twisting or rotation of the wire significantly reduces the amount of force required to disengage the wire from the connector. The contact engagement effectively cuts helical threads into the conductor during rotation, resulting in an unscrewing of the conductor from the connector.
- Therefore, what is needed is a system that provides strain relief and/or reduces or eliminates unintentional release of wires from plug-in connectors when the wire is being pulled and twisted or rotated.
- A prior art connector is disclosed in patent
US 3836938 . The connector includes a socket with a body on opposite sides of which supporting means are provided which are connected by a pair of through rivets, screws or bolts which act to hold the supporting means to the socket body and clamp cables extending therefrom between clamping flange extensions of the supporting means so as to prevent the cables extending from the socket body from being accidentally pulled out of sockets located in the socket body. PatentUS 4868905 discloses an electric motor body with first and second exterior slots arranged at right angles to each other and through which a power lead can be led. PatentUS 3909099 provides an electrical connector as recited in the preamble of claim 1. - According to the invention there is provided a method of connecting a wire to an electrical connector comprising the steps of: (i) providing a connector having a connector housing having at least one opening configured to receive the wire along an opening center axis and a wire retention member with a wire guide, wherein an arm extends from the wire retention member to form a slot between said arm and the connector housing, said arm further includes the wire guide and an arm slot, which are configured to permit insertion of the wire through said wire guide and into said opening; (ii) inserting the wire through the wire guide into the opening; and (iii) removing the wire from the wire guide through the arm slot in the wire guide, to provide a joggle or bend in the wire to provide resistance to pulling and rotation of the wire.

FIGs. 1-4 show a wire retaining system having anwire terminal 100 that is configured to be locked into connector housing 400 (seeFIG. 4 ) and to lockingly receiveelectrical wire 105.Electrical wire 105 includesconductor 107 andinsulation 109. The configuration ofwire 105 may be any configuration of wire that includes an insulated conductive portion.Suitable wires 105 include, but are not limited to, 18-gauge solid-core copper wire.Wire terminal 100 includes aterminal body 103, a locking portion ormember 111, defining a lockingshoulder 113 for engaging a surface of a connector housing 400 (see, e.g.,FIG. 4 ) to securely retainwire terminal 100 withinconnector housing 400. - As best viewed in
FIG. 2 ,terminal body 103 further includes acontact gripping element 201 arranged extending into anaperture 205 withinterminal body 103.Terminal body 103 further includes astop 207 in electrical communication withterminal body 103 that provides a surface onto which aconductor 107 may abut to establish a maximum insertion of wire 105 (see, e.g.,FIG. 3 ) insideterminal body 103. Stop 207 may be formed fromterminal body 103 or may be attached to theterminal body 103. Thecontact gripping element 201 may be cut or stamped out fromterminal body 103, but as shown, is stamped from a blank of material from which it is formed. Alternatively, contact grippingelement 201 may be separately provided and secured toterminal body 103. In this embodiment,wire terminal 100 is of unitary construction. Contact grippingelement 201 may be resiliently biased into the form of, for example, a leaf spring or beam structure. Thecontact gripping element 201 defines a wire trap for contacting an exposed conductor of an insulated wire or a conductor of an uninsulated wire or an electrically conductive contact having a similar cross-section. In the embodiment shown inFIGs. 1-4 , thewire terminal 100 further includes ablade 117 extending inwardly from theterminal body 103 intoaperture 205 toward aterminal center axis 203. - As shown in
FIGs. 1 and3 ,conductor 107 ofwire 105 is installed inwire terminal 100 by directingconductor 107 alongterminal center axis 203post blade 117 towardend 303 untilconductor 107 abuts stop 207. Stop 207 is shown as a tab that is biased inwardly intoaperture 205. However, stop 207 may also include a region of reduced cross-sectional area to provide a surface toabut conductor 107 when fully inserted insideaperture 205. - As best shown in
FIG. 1 ,blade 117 preferably extends towardterminal center axis 203 perpendicularly toterminal center axis 203. The extension of theblade 117 towardterminal center axis 203 is preferably such that theblade 117 contacts theinsulation 109 ofwire 105 inserted interminal 100. This contact is such that theblade 117 slices or shears a groove or channel 301 (seeFIGs. 3-4 ) in theinsulation 109 during insertion of thewire 105 into the terminal with thechannel 301 providing an engagement with thewire 105 to substantially prevent axial rotation between thewire 105 and the wire terminal aboutterminal center axis 203. Theblade 117 may also include a tapered edge (not shown) arranged parallel toterminal center axis 203 to reduce the force associated with insertingwire 105 and formingchannel 301. The position ofblade 117 may be any circumferential position onterminal body 103 that permits extension ofblade 117 towardwire 105. That is,blade 117 may extend intoaperture 205, but not necessarily aligning withterminal center axis 203. The extension ofblade 117 may provide achannel 301 in theinsulation 109, theconductor 107 or any combination thereof. In one embodiment of the invention, theblade 117 may be incorporated intocontact gripping element 201 wherein thechannel 301 is formed on theconductor 107. In addition, a plurality ofblades 117 may be utilized to further resist wire rotation. -
FIG. 4 shows a cross-sectional view of a connector housing illustrating awire terminal 100 arranged within theconnector housing 400, with a portion of theconnector housing 400 removed. Lockingmember 111 at the lockingshoulder 113 engages surface of theconnector housing 400 to substantially prevent disengagement of thewire terminal 100 from theconnector housing 400.Connector housing 400 may be configured in any manner that mates a second connector housing (see, e.g.,FIG. 13 ), wherein each of theconnector housing 400 andwire terminal 100 receives and engages aconductor 107 of awire 105 for electrical connection ofwires 105 to the second connector.Connector housing 400 is preferably fabricated from a non-electrically conductive material, such as, for example, conventional engineering grade thermoplastic. As shown inFIG. 4 , theconnector housing 400 and thewire terminal 100 are configured as a female connection viaaperture 205 atend 303 for receiving a male plug. Whilewire terminal 100 is shown as including a female connection atend 303, thewire terminal 100 may include a male plug atend 303 or any other structure that permits electrical communication between engaged connector housings. Theconnector housings 400 may be engaged in any suitable manner, including but not limited to, disenagable latches 401 that are disengagable by depressinglatch arms 403. Mating connector housings (not shown inFIG. 4 ) may include latch features 1301 (see, e.g.,FIG. 13 ) that engage latches 401 and substantially prevent disengagement of theconnector housings 400. In addition,connector housing 400 includes opening 405 that may have mating geometries that permit orientation of mating plugs only in desired configurations. Engagement ofconnector housings 400 and theircorresponding wire terminals 100 permits safe and easy electrical connection/disconnection ofwires 105 without the necessity of crimping, special tools or equipment. As shown inFIG. 4 , a plurality ofwires 105 may be inserted intoconnector housing 400, wherein the arrangements ofcorresponding wire terminals 100 may be the same or different than the arrangement shown inFIG. 4 . - The engagement of
blade 117 with rotation resistance is achieved by formation ofchannel 301, whereinchannel 301 has sufficient depth intoinsulation 109 and/orconductor 107 to provide substantial resistance to rotation aboutterminal center axis 203. While it is preferable to providechannel 301 into theinsulation 109 only, thechannel 301 may also be formed intoconductor 107. This rotational resistance allows thewire 105 engaged or trapped bycontact gripping element 201 to remain engaged and substantially prevents unintentional disengagement ofwire 105 due to rotation and pulling ofwire 105 aboutterminal center axis 203.Additional blades 117 provide additional rotational resistance, but also increase the amount of force required to insertwire 105. -
FIG. 5 shows a cross-sectional view of another connector with a portion of theconnector housing 400 removed, including awire terminal 100 according to an embodiment of the present invention arranged withinconnector housing 400. The embodiment shown inFIG. 5 includes substantially the same arrangement ofconnector housing 400 andwire terminal 100 substantially as shown and described inFIG. 4 . Thewire terminal 100 in the embodiment shown inFIG. 5 may or may not includeblade 117. However,connector housing 400 further includes anangle channel 501 configured to conform wire 105 (i.e., bend) in a plurality of axes, including axes different thanterminal center axis 203. During insertion ofconductor 107 intoconnector housing 400, the wire is directed alongangle channel 501 in a direction at an angle toterminal center axis 203. As theconductor 107 is further inserted towardend 303 and pastangled channel 501, theconductor 107 is directed alongterminal center axis 203. Upon full insertion ofconductor 107, thewire 105 andconductor 107 are configured into at least a firstwire orientation section 503 which is oriented substantially parallel to and/or coincident with about theterminal center axis 203, a secondwire orientation section 505 which is oriented substantially parallel to and/or coincident with about anangle channel axis 506 and a thirdwire orientation section 507, which is oriented substantially parallel to and/or coincident with about afront opening axis 508. While the above has been described as three axes, the orientation of the insertedwire 105 may include greater than three axes and may include curved, rounded or twisted orientations along theangle channel 501 or exterior to theconnector housing 400. As shown inFIG. 5 , a plurality ofwires 105 may be inserted intoconnector housing 400, wherein the arrangements ofcorresponding wire terminals 100 and the presence and arrangement ofangle channel 501 may be the same or different than the arrangement shown inFIG. 5 . For example,angle channel 501 may include multiple orientations for directingwire 105 into a plurality of directions. Likewise, theangle channel 501 may be oriented at any angle or direction that provides an angle toterminal center axis 203. This embodiment of the present invention permits the easy engagement ofwire 105 while reducing or eliminating undesired/unintentional disengagement ofwire 105 from thewire terminal 100 and/or theconnector housing 400. -
FIG. 6 illustrates a wire retaining system, including aconnector housing 400 havingopenings 600 configured to receive wires 105 (not shown inFIG. 6 ). Circumferentially about a surface ofopening 600, at least onerib 601 is configured to receivewire 105. Preferablyribs 601 are configured to engage theinsulation 109 ofwire 105. Theribs 601 may be of certain construction with theconnector housing 400 or may be attached toopening 600. Theribs 601 are preferably a non-conductive material of sufficient rigidity and having a geometry that grips theinsulation 109 and resists or prevents rotation ofwire 105 whenwire 105 is inserted rotationally about openingcenter axis 603. In another wire retaining system, a conductive material, such a metal may be utilized in theconnector housing 400 or as insert thereto, formingribs 601 forgripping wire 105. Theribs 601 may be oriented at an angle toopening center axis 603 or perpendicular toopening center axis 603. In other words,ribs 601 may or may not radially extend in alignment withopening center axis 603. In addition,ribs 601 preferably sufficiently engageinsulation 109 that the resistance to undesired/unintentional disengagement parallel toopening center axis 603 is likewise increased. As shown,ribs 601 are arranged substantially parallel to theopening center axis 603 ofopening 600. -
FIG. 7 illustrates a wire retaining system, including aconnector housing 400 havingopenings 600 configured to receive wires 105 (not shown inFIG. 7 ).Openings 600 may includeribs 601, as shown and described above with respect toFIG. 5 , and/or theconnector housing 400 may includewire terminal 100 structures, as described above with respect toFIGs. 1-5 . Theconnector housing 400 further includes asegmenting slot 700 extending through bothopenings 600 and through theconnector housing 400. The segmentingslot 700 is formed into theconnector housing 400 coplanar to a center axis of thewire 105 and provides a compliant force on an insulation portion of thewire 105 by segmenting portions of the connector body into pivoting portions. Segmentingslot 700 forms a pivotabletop member 701 and apivotable bottom member 703. Pivoting oftop member 701 andbottom member 703 preferably is facilitated by elastic deformation of the material making upconnector housing 400 but may be provided by an attached mechanical or formation of a hinge or hinge-like structure. The pivoting of thetop member 701 and/or thebottom member 703 decreases the resistance (i.e., force required for insertion) on the wire 105 (not shown inFIG. 7 ) by allowing a reduced force onwire 105 due to contact withtop member 701 andbottom member 703 and structures, such asribs 601, extending inwardly alongopenings 600. The reduced resistance to insertion permits the utilization of additional wire retention structures, such asblade 117,contact gripping element 201 andribs 601, and other structures that increase resistance toelectrical wire 105 insertion, intoconnector housing 400. This wire retaining system permits the simple and easy engagement ofwire 105 while permitting the use of wire retention structures to reduce or eliminate undesired/unintentional disengagement ofwire 105 from thewire terminal 100 and/or theconnector housing 400. -
FIG. 8 illustrates a wire retaining system, including aconnector housing 400 havingopenings 600 configured to receivewires 105.Connector housing 400 may includewire terminal 100 structures (not shown inFIG. 8 ) and/orribs 601 to provide wire retention, as described above with respect toFIGs. 1-6 . However, the wire retaining system shown inFIG. 8 further includes aretention plate 800 havingopenings 600 configured to allow insertion ofwire 105. In addition, the periphery of opening 600 includes a plurality offingers 801 extending inward toward theopening center axis 603 ofopening 600. Thesefingers 801 are configured to grip theinsulation 109 ofwire 105 and provide resistance against unintentional disengagement ofwire 105 in response to a pulling and/or twisting force directed alongopening center axis 603.Plate 800 is preferably a non-electrically conductive material, such as a polymeric material that is sufficiently rigid to provide resistance in response to pulling and/or twisting forces directed alongopening center axis 603. For example,plate 800 may be fabricated from a mylar film.Plate 800 is preferably attached to a surface ofconnector housing 400.Plate 800 may be attached toconnector housing 400 in any conventional manner, including, but not limited to adhesives or thermal bonding. However,plate 800 may also be fabricated as a unitary piece withconnector housing 400. In addition,plate 800 may be partitioned into afirst plate segment 803 and asecond plate segment 805, wherein each plate segment may be provided with color, marking or other indicia to indicate proper installation and/or configuration ofwires 105. The addition ofplate 800 to theconnector housing 400 provides resistance against undesirable/unintentional disengagement ofwire 105 in response to a pulling force directed alongopening center axis 603. -
FIG. 9 illustrates a wire retaining system, including aconnector housing 400 havingwire terminal 100 incorporated therein. The wire retaining system shown inFIG. 9 includes substantially the same arrangement ofconnector housing 400 andwire terminal 100 substantially as shown and described inFIG. 4 . Thewire terminal 100 in the wire retaining system shown inFIG. 5 may or may not includeblade 117.Opening 600 is formed intoconnector housing 400, wherein opening is configured to receive a gripping structure orgrommet 900.Grommet 900 includes a non-electrically conductive material, such as a polymeric or rubber material, which grip and/or apply frictional sliding resistance to wire 105 and/orconnector housing 400. Thegrommet 900 may be incorporated intoconnector housing 400 or may be attached or installed ontowire 105. Thegrommet 900 may also utilize an adhesive, such as a pressure sensitive adhesive tofurther grip wire 105 and provide additional resistance in response to pulling and/or twisting. Thegrommet 900 preferably provides sufficient frictional sliding resistance to substantially prevent undesirable/unintentional disengagement ofwire 105 fromwire terminal 100 and/orconnector housing 400. -
FIG. 10 illustrates a wire retaining system, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 10 ) incorporated therein for receiving a wire 105 (not shown inFIG. 10 ).Connector housing 400 further includes aretention member 1000, which extends fromconnector housing 400.Retention member 1000 includes a "T" shape, whereinarms 1003 extend to form aslot 1005 betweenarms 1003 andconnector housing 400.Slot 1005 has a geometry permitting the insertion of a wire or cable tie 1201 (see e.g.,FIG. 12 ), or other device capable of substantially immobilizingwires 105.Cable tie 1201 may be inserted intoslot 1005, wherein the wire retention structure provides surfaces that prevent thecable tie 1201 from slipping or moving in a direction away fromconnector housing 400. Thecable tie 1201 also provides wire retention by providing a sufficient circumferential force inward towardretention member 1000 to retainwires 105 adjacent toretention member 1000 and substantially prevent undesirable/unintentional disengagement ofwire 105 fromwire terminal 100 and/orconnector housing 400. In addition,wire 105 may be oriented around (i.e., wrapped around)wire retention member 1000 in a manner that provides orientation ofwire 105 in a plurality of axes and provides additional resistance to pulling and/or twisting. -
FIG. 11 illustrates a wire retaining system, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 11 ) incorporated therein for receiving a wire 105 (not shown inFIG. 11 ).Connector housing 400 further includes aretention member 1000, which extends fromconnector housing 400.Retention member 1000 is formed into a "T" shape, whereinarms 1003 extend to form aslot 1005 betweenarms 1003 andconnector housing 400.Arms 1003 further include wire guides 1101, which are configured to permit insertion ofwire 105 through the wire guides 1101 and intoopening 600. The wire guides 1101 form openings or channels through which the wire may be inserted to permit the guided insertion ofwires 105 intoopenings 600.Retention member 1000 may be formed intoconnector housing 400 as a unitary piece or may be attached toconnector housing 400. -
FIG. 12 includes a connector including the retention member shown and described with respect toFIG. 11 . In addition,FIG. 12 includeswires 105 and acable tie 1201 arranged inslots 1005 wherein thecable tie 1201 provides at least a partial inwardly directed circumferential force to retainwires 105 in position.Cable tie 1201 is any device capable of providing a force onwires 105 within slot orslots 1005 that provides resistance to both pulling and rotation. In addition to cable ties, adhesive structures, such as tape, labeling or other wire immobilizing device may also be utilized. The inward retaining force provided bycable tie 1201 is preferably sufficient to provide resistance to unintentional disengagement of thewires 105 due to pulling of thewires 105 and/or rotation of thewires 105. -
FIG. 13 illustrates a cross-sectional view ofconnector housing 400 engaged with a second connector housing 400', wherein thewire 105 and wire terminal 100,100' are shown in elevational cross-sectional view. The connection ofconnector housings 400 and 400' permits the electrical connection ofwire 105 with wire 105' by electrical communication betweenwire terminal 100 and 100' atjunction 1300.Junction 1300 preferably includes coupling of a male plug with a female connection, each corresponding to one ofconnector housing 400 or connector housing 400'. The engagement ofconnector housing 400 to connector housing 400' takes place by engagement of disenagable latches 401 of connector housing 400' engagingconnector feature 1301 ofconnector housing 400. The engagement of disengagable latches 401 andconnector feature 1301 provides a latched position capable of resisting a retention force between theconnector housings 400 and 400'. - In a preferred wire retaining system, the wire retention of
wires 105 is sufficient that forces onwire 105 provide for disengagement oflatches 401 andfeature 1301 at a lesser force than the force required to disengagewires 105 fromconnector housing 400. - As further shown in
FIG. 13 ,cable tie 1201 may be positioned inslot 1005,adjacent wire 105. Thecable tie 1201 provides force againstwire 105 andretention member 1000. The force provided bycable tie 1201 provides resistance to or prevention of unintentional disengagement ofwire 105 in response to a pulling force directed alongopening center axis 603. -
FIG. 14 illustrates a wire retaining system, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 14 ) incorporated therein for receiving a wire 105 (not shown inFIG. 14 ).Connector housing 400 includesopening 600, wherein the opening may extend along a substantially singular axis to wire terminal 100 (see, e.g.,FIG. 4 ), or may include anangle channel 501, such as the structure shown inFIG. 5 .Connector housing 400 further includes aretention member 1000, which extends fromconnector housing 400.Retention member 1000 is formed into acenter retention member 1400 and twoside retention members 1403 each configured to provide awire retention guide 1401, which receives thewire 105 and provides a joggle or bend in thewire 105, which provides resistance to pulling and rotation, once thewire 105 is engaged inwire retention guide 1401. -
FIG. 15 shows theconnector housing 400 shown and described with respect toFIG. 14 wherein awire 105 is installed in eachwire retention guide 1401. Thewire 105 may be installed by insertingwire 105 alongopening center axis 603. Thewire 105 is inserted intoconnector housing 400 untilwire 105 is engaged with wire terminal 100 (not shown inFIG. 15 ). After thewire 105 is fully inserted, thewire 105 protruding from opening 600 is then brought into contact with a surface ofwire retention member 1000 betweencenter retention member 1400 and one of the twoside retention members 1403. Thewire 105 is then guided intowire retention guide 1401. Thewire 105 is preferably permitted to snap into thewire retention guide 1401 by elastic deformation of thewire retention member 1000. Snapping, as used herein, indicates a compliant force or elastic resistance that permits the introduction and/or retention of awire 105 or other structure by virtue of a force that is overcome by application of a greater counter force. In other words, spacing betweenside retention member 1403 andcenter retention member 1400 is less than the diameter ofwire 105, the elastic resistance betweenside retention member 1403 andretention member 1400 initially presenting access ofwire 105 intowire retention guide 1401. However, upon application of sufficient force applied towire 105,wire 105 overcomes the retention force betweenside retention member 1403 andretention member 1400 and decreasewire retention guide 1401. Upon accessingwire retention guide 1401, thewire 105 may then be further oriented or bent to the desired direction of wire installation. Theretention member 1000 retains thewire 105 in position with a plurality of bends aligned in a plurality of axes. These bends provide addition resistance to pulling along theopening center axis 603 and resists or prevents undesirable/unintentional disengagement ofwire 105 fromconnector housing 400.Retention member 1000 is configured to provide awire retention guide 1401, which receives the wire and provides a joggle or narrow bend portion in thewire 105, which provides resistance to pulling and rotation, once thewire 105 is engaged inwire retention guide 1401. -
FIG. 16 illustrates aconnector housing 400 engaged with a second connector housing 400'.Connector housing 400 and connector housing 400' are engaged in the manner shown and described above with respect toFIG. 13 . As shown,wire 105, 105' is positioned withinwire retention guide 1401, 1401' ofwire retention member wire 105, 105' andretention member wire 105, 105' in response to a pulling force directed alongopening center axis 603. -
FIG. 17 illustrates a wire retaining system according to an embodiment of the present invention, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 17 ) incorporated therein for receiving a wire 105 (not shown inFIG. 17 ).Connector housing 400 further includes aretention member 1000, which extends fromconnector housing 400.Retention member 1000 is formed into a "T" shape, whereinarms 1003 extend to form aslot 1005 betweenarms 1003 andconnector housing 400.Retention member 1000 may be formed intoconnector housing 400 as a unitary piece or may be attached toconnector housing 400.Arms 1003 further includewire guide 1101 andarm slot 1701, which are configured to permit insertion ofwire 105 throughwire guide 1101 and intoopening 600, wherein thewire 105 may further be brought into contact witharm slot 1701 and permitted to snap out ofwire guide 1101 by elastic deformation or other mechanism ofarm 1003 adjacent toarm slot 1701, such as previously discussed with regard toFIG. 15 . The positioning of thewire 105 outside thewire guide 1101 permitswire 105 to be oriented along a plurality of axes (i.e., to have a plurality of bends). These bends provide addition resistance to pulling along theopening center axis 603 and resists or prevents undesirable/unintentional disengagement ofwire 105 from connector housing 400 (see, e.g.,FIGs. 21 and22 ). Thus, removal ofwire 105 fromwire guide 1101 througharm slot 1701 provides a joggle or bend in thewire 105, which provides resistance to pulling and rotation once the wire is engaged adjacent toretention member 1000. -
FIG. 18 illustrates a wire retaining system according to another embodiment of the present invention, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 18 ) incorporated therein for receiving a wire 105 (not shown inFIG. 18).

FIG. 19 illustrates a wire retaining system according to still another embodiment of the present invention, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 19 ) incorporated therein for receiving a wire 105 (not shown inFIG. 19). FIG. 19 includes substantially the same arrangement ofconnector housing 400,openings 600,wire retention member 1000,arm 1003,wire guide 1101, andarm slot 1701, as shown and described with respect toFIG. 17 . However, the embodiment shown inFIG. 19 further includes guard features 1901 configured to permit the passage ofwire 105 out ofwire guide 1101, but substantially prevents the reinsertion ofwire 105 intowire guide 1101. In addition, the guard features 1901 act to limit rotation of the wire disposed within theslot 1005. Specifically, the guard features preferably provide guidance for the wire to a position away fromarm slot 1701 and substantially confines movement ofwire 105 to either side ofguard feature 1901. -
FIG. 20 illustrates a wire retaining system according to still another embodiment of the present invention, including aconnector housing 400 having wire terminal 100 (not shown inFIG. 20 ) incorporated therein for receiving a wire 105 (not shown inFIG. 20).

Thesidewalls 2000 andwire retention member 1000 are configured to provide aside opening 2003 for receiving and retaining wire 105 (seeFIG. 21 ). The configuration ofFIG. 20 provides improved strength of thewire retention member 1000 by formation ofsidewalls 2000, which resists breakage. In addition, the formation ofsidewalls 2000 reduces or eliminates surfaces susceptible to snagging, particularly during storage and/or transportation, wherein a plurality of wire connector systems and their associatedwires 105 may be present. In addition, the reentry of the wire intoslot 1701 is made difficult because the formation ofsidewall 2000 provides a surface against which little or no deflection may take place. In other words, in order forwire 105 to reenter wire guide, thearm 1003 must deflect a distance substantially equal to the diameter ofwire 105, which requires a greater force than deflection of two opposingarms 1003, as shown, for example, inFIG. 17 . -
