Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to electrical connectors and, more particularly, to a connector for splicing two conductors together.




2. Prior Art




U.S. Pat. No. 4,698,031 discloses a connector for ends of two conductors. The connector has two sets of jaws and springs biasing the jaws in opposite directions for automatically clamping onto an inserted conductor. There is a desire to provide a connector similar to that disclosed in U.S. Pat. No. 4,698,031, but which can have additional features such as a pre-latching feature for the jaws, an anti-reverse system for the jaws, or a spring system which can reduce the length of the connector.




SUMMARY OF THE INVENTION




In accordance with one embodiment of the present invention, an electrical splice connector is provided comprising a frame, at least one set of cooperating wedge members movably mounted to the frame, and a first spring connected between a first one of the wedge members and the frame. The wedge members have opposing sides adapted to contact opposite sides of an electrical conductor. The spring extends at least partially along a length of the first wedge member.




In accordance with another embodiment of the present invention, an electrical splice connector is provided comprising a frame having an open side for receiving ends of two oppositely extending electrical conductors through the open side; a first wedge movably connected to the frame along a first length of the frame; and a second wedge movably connected to the frame along a second length of the frame which is spaced from the first length. The end of a first one of the electrical conductors can be inserted through the open side of the frame and contact the first wedge. The end of a second one of the electrical conductors can be inserted through the same open side of the frame and contact the second wedge.




In accordance with another embodiment of the present invention, an electrical splice connector is provided comprising a frame having two ends with a conductor passage aperture in each end and a side between the two ends which has a conductor entrance aperture contiguous with the passage apertures; and a first set of cooperating wedge members movably mounted to the frame. Each wedge member is located and retained in a separate retaining groove of the frame. The wedge members have opposing surfaces adapted to contact opposite sides of an electrical conductor. The conductor is inserted through the entrance aperture and extends out of a first one of the end passage apertures. The wedge members of the first set directly contact each other to move with each other along the frame.

generally comprises a middle section


20


and two sections


22


,


24


connected to each other by the middle section


20


. The two sections


22


,


24


are substantially mirror images of each other. However, in alternate embodiments they could be different. Each section


22


,


24


has opposite side walls


26


,


28


which are angled relative to each other to form wedge shaped receiving areas


30


,


32


. The frame


12


can have stiffening ribs to strengthen the wedge sections


22


,


24


. The frame


12


has a substantially open top side which extends into the receiving areas


30


,


32


. The opposite ends of the frame


12


have conductor passage apertures


34


,


36


into the receiving areas


30


,


32


. In this embodiment the middle section


20


is open on three sides. The tops of the side walls


26


,


28


include inwardly extending retaining lips


38


. In this embodiment, one side


40


of the frame forms a common side for all three sections


20


,


22


,


24


. At the middle section


20


, the side


40


includes two latching bosses or projections


42


and two series of serrations or grooves


44


. The side

also includes spring grooves


46


and guide rails or projections


48


. In alternate embodiments the frame could have more or less features, the features could be arranged in any suitable manner on the frame, and/or the features could have any suitable size or shape.




The two wedges


14


,


16


are substantially the same, but merely orientated in reverse orientations relative to each other. However, in alternate embodiments more or less than two wedges could be provided, and the wedges could have different shapes. Referring also to

FIGS. 3 and 4

, in this embodiment each wedge has two wedge members


50


and


52


. However, in alternate embodiments each wedge could have more or less than two wedge members. The first wedge member


50


is preferably a one-piece cast metal member. However, in alternate embodiments the first wedge member


50


could be comprised of multiple members, could be comprised of any suitable material(s), and/or could be manufactured by any suitable process.




The first wedge member


50


generally comprises four sides


54


,


56


,


58


,


60


located between a front end


62


and a rear end


64


. The inner side


54


has a curved conductor contact surface


66


. The inner side


54


, proximate the bottom side


58


, also comprises a wedge member interlock projection


70


. The top side


56


has a finger contact section


68


adapted to allow a finger of a user to move the first wedge member. However, in an alternate embodiment the finger contact section might not be provided, or any suitable type of section for direct interaction with the user could be provided. The thickness of the first wedge member


50


between the two lateral sides


54


and


60


increases from the front end


62


to the rear end


64


to form a general wedge shape. The bottom side


58


generally comprises a latching recess


72


, a spring contacting section


74


, and a groove


76


.




The sides


60


of the first wedge members


50


are located against the inner surfaces of the sides


28


of the frame


12


. The bottom sides


58


are located against the side


40


of the frame


12


with the spring contacting section


74


extending into respective ones of the spring grooves


46


. One of the guide projections


48


extends into each of the grooves


76


. The retaining lips


38


of the sides


28


extend over a portion of the top sides


56


of the first wedge members.




The second wedge member


52


is preferably a one-piece cast metal member. However, in alternate embodiments the second wedge member


52


could be comprised of multiple members, could be comprised of any suitable materials(s), and/or could be manufactured by any suitable process. The second wedge member


52


generally comprises four sides


78


,


80


,


82


,


84


located between a front end


86


and a rear end


88


. The inner side


78


has a curved conductor contact surface


90


. The inner side


78


, along the bottom side


82


, also comprises a wedge member interlock recess


92


. The thickness of the second wedge member


52


between the two sides


78


and


84


increases from the front end


86


to the rear end


88


to form a general wedge shape. The bottom side


82


generally comprises a recess


94


, a spring contacting section


96


, and a groove


98


.




The second wedge members


52


are located against the inner surfaces of the sides


26


of the frame


12


. The bottom sides


82


are located against the side


40


of the frame


12


with the spring contacting section


96


extending into respective ones of the spring grooves


46


. Respective ones of the guide projections


48


extend into the grooves


98


. The retaining lips


38


of the sides


26


extend over a portion of the top sides


80


. In the embodiment shown, the second wedge members


52


also each comprise a clip


100


(see FIG.


5


). The clip


100


has a mounting section


102


and a latch section


104


. The clip


100


could be comprised of sheet metal or any other suitable material. The mounting section


102


is fixedly attached to the second wedge member


52


in the recess


94


by any suitable means. The tips


106


of the latch section


104


extend in a downward direction from the bottom side


82


of each second wedge member. However, in alternate embodiments the clip


100


might not be provided, or could be attached to the first wedge members, or could have any suitable shape, or could be formed integrally with the second wedge member.




The springs


18


, in the embodiment shown, are coil springs, but any suitable springs could be provided. In this embodiment a spring


18


is provided for each wedge member


50


,


52


. However, in alternate embodiments more or less springs could be provided, such as one spring for each pair of wedge members


50


,


52


. The springs


18


in this embodiment are intended to be compression springs. The springs


18


are located in respective ones of the spring grooves


46


. One end of each spring


18


is located against the inward closed end


47


of its respective groove


46


. The opposite end of each spring is located against one of the spring contact sections


74


,


96


. In the embodiment shown the spring contact sections


74


,


96


merely comprise projecting bosses. However, in alternate embodiments any suitable type of spring contact sections could be provided. The compression springs


18


exert forces on the wedge members


50


,


52


to bias the wedges


14


,


16


towards the ends of the frame


12


. The wedge spring mechanism is a feature that causes the wedges to put an initial force on the conductor during the insertion. The force is such that it maintains enough friction between the wedges and the conductor such that, as the conductor is pulled during installation, it allows the wedges to “set” without the conductor slipping through the wedges. In one embodiment the connector utilizes a compression spring for each wedge to develop the force. In another embodiment the connector utilizes an extension spring for each wedge to develop the force. The wedges have interlocking fingers that prevent one wedge advancing at a different rate than the other. In both embodiments the grooves for the springs are in the base of the body of the connector opposed to the sides of the body of the connector. This allows the wedges to be designed such that the maximum surface of the wedge is in contact with the sides of the body of the connector. This permits the greatest surface contact for electrical conduction between the wedges and the body of the connector. The orientation of the grooves and springs also makes the need for additional sheet metal components unnecessary.




As noted above, the wedge members


50


,


52


comprise an interlock projection


70


and an interlock recess


92


, respectively. The projection


70


of the wedge member


50


extends into the recess


92


of the opposite wedge member


52


for each wedge


14


,


16


. This interlocks the pairs of wedge members


50


,


52


to each other to move together in directions C relative to the longitudinal axis of the receiving areas


30


,


32


and frame


12


. However, the pairs of wedge members


50


,


52


for each wedge


14


,


16


are able to move or slide relative to each other in directions D, transverse to directions C, while still being interlocked with each other. In alternate embodiments any suitable type of movable interlocking engagement between pairs of wedge members could be provided, or no interlocking engagement could be provided.




The embodiment shown in

FIG. 1

includes a latch system comprising the latching bosses


42


and the latching recesses


72


. However, in alternate embodiments the connector might not have a latching system, or any suitable type of system for latching or retaining the wedges in rearward positions could be provided. Referring also to

FIG. 6

, the bosses


42


and recesses


72


are suitably sized and shaped relative to each other, and the bosses


42


are suitably orientated at the rear of the path of the first wedge members


50


, such that the bosses


42


can extend into the recesses


72


when the first wedge members


50


are in rearward retracted positions on the frame


12


; i.e.: located at middle section


20


. Each boss


42


has a rear latching surface


108


and a ramp surface


110


. Each first wedge member


50


has a latch surface


112


in the rear of the recess


72


and a ramp surface


114


behind the recess


72


on the bottom side


58


. When the latching surfaces


108


,


112


contact each other, the first wedge member


50


is latched to the frame


12


at its rearward position and, even though its spring


18


exerts a biasing force against the first wedge members


50


, is prevented from moving forward towards one of the ends of the frame. Because of the interlock between pairs of the wedge members


50


,


52


, the associated opposite second wedge member


52


is also prevented from moving forward even though its spring exerts a biasing force against it. The ramp surfaces


110


and


114


allow the first wedge member


50


to be more easily moved onto the boss


42


. The finger contact sections


68


of the first wedge members


50


allow the wedges to be more easily moved by the user to the rearward positions, such as by clamping the two finger contact sections


68


in a single hand, between thumb and forefinger, and squeezing. The finger contact sections


68


also provide a convenient location for a user to grasp the first wedge member


50


and lift its rear end up, as indicated by arrow E in

FIG. 6

, to disengage the two latching surfaces


108


,


112


from each other and allow the springs


18


to move the wedge members


50


,


52


on the frame


12


towards the ends of the frame and towards the conductor clamping positions for the wedges


14


,


16


. The pre-latching feature keeps the jaws open for ease of conductor insertion during installation. In one embodiment a small recess in the underside of one of the wedges (wedge which has finger tab) and a small boss in the surface of the connector body accomplish this. When the wedges are retracted to insert the conductor the boss engages with the recess in the bottom of the wedge keeping the wedges open temporarily. To close the wedges, the finger tab on the wedge is lifted up causing the recess to disengage from the boss.




The embodiment shown in

FIG. 1

includes an anti-reverse feature comprising the serrations


44


on the frame


12


and the clips


100


on the second wedge members


52


. However, in alternate embodiments the connector might not have an anti-reverse feature, or any suitable type of anti-reverse feature for preventing the wedges


14


,


16


, once moved towards their conductor clamping positions could be provided, from moving back towards their retracted positions. Referring also to

FIG. 7

, the serrations


44


preferably comprise a rear surface


116


having a steep slope and a front surface


118


having a more shallow slope. The tips


106


of the latch section


104


of the clips


100


can extend into the serrations. Because of the shallow slope of the front surfaces


118


of the serrations


44


, the latching sections


104


can relatively easily resiliently deflect out of the serrations (one at a time) as the second wedge members


52


are moved forward in direction C


F


on the frame


12


; towards their respective frame ends. However, if the second wedge member


52


is attempted to be moved in a reverse reward direction C


R


, the steep slope of the rear surface


116


and shape of the latch section


104


combine to block such rearward movement. This helps to insure that once the wedges


14


,


16


clamp onto a conductor, they stay attached even if subjected to vibrations or temporary subsequent push-in of the conductor A or B. The anti-reverse feature prevents the wedges from disengaging from the conductor once the wedges are set on the conductor. One embodiment utilizes a strip spring attached to the underside of one of the wedges and a series or serrations on the connector body surface. As the wedge tightens onto the conductor, the strip spring progressively “clicks” into each successive serration. The serrations are designed such that they allow the spring to advance to the next serration as the wedges tighten around the conductor. This is accomplished by the geometry of the edges of the serrations. The edge of the serration that leads to the next serration as the wedge advances is angled. This allows the spring to freely disengage and then engage with the next serration. The edge of the serration adjacent to the previous serration is perpendicular to the body of the connector. This prevents the spring from disengaging and retracting to the previous serration. Thus, the spring


100


is free to advance forward to the next serration, but cannot go back to the previous serration.




Once the connector


10


is assembled, its use is relatively simple. The wedges


14


,


16


are maintained in their rearward pre-connection positions by the latch system


42


,


72


. The conductor A is inserted in receiving area


32


between the opposite conductor contact surfaces


66


,


90


of the wedge members


50


,


52


. The conductor A can be inserted through the open top side of the frame


12


or through the end aperture


36


. In either event, the conductor A extends out of the end aperture


36


. The user then lifts the rear end of the first wedge member


50


by means of the finger contact section


68


to disengage the latch system


42


,


72


. The springs


18


automatically push the wedge members towards the end of the frame; towards the end aperture


36


. The slide paths of the wedge members


50


,


52


are angled relative to each other such that the wedge members


50


,


52


move towards each other as they approach the end aperture


36


. The surfaces


66


,


90


move into contact with opposite sides of the conductor A and clamp onto the conductor. Thus, the wedge


16


connects the conductor A to the frame


12


. The user can then pull on the conductor to more securely wedge the wedge members


50


,


52


and conductor with each other in the wedge shaped receiving area


32


. The wedge


14


can operate in a similar fashion to connect the conductor B to the frame


12


. Thus, the connector


10


can electrically and mechanically connect the conductors A, B to each other. For each wedge, because of the interlocking nature of the pair of wedge members


50


,


52


, they can simultaneously move together to clamp onto the conductors. The embodiment shown in

FIG. 1

provides a relatively open frame which allows a user to actively see if the conductors A, B are fully inserted and if the wedge members


50


,


52


move properly to clamp onto the conductors. The ends of the conductors A, B can be located along a common axis. However, the location of the springs


18


offset from the paths of the wedge members


50


,


52


and axes of the conductors allows the frame


12


to have a shorter longitudinal length than conventional designs. However, in alternate embodiments the conductors might not have a common axis and the spring(s) might not be offset. The guide rails


48


and guide grooves


76


,


98


help to insure proper spreading and closing of the wedge members relative to each other. The surfaces


66


,


90


could have teeth to project or bit into the conductors.




Referring now to

FIG. 8

an exploded perspective view of an alternate embodiment is shown. In this embodiment the connector


120


is very similar to the connector


10


. However, the springs


122


are tension springs rather than compression springs. The frame


124


has extensions


126


at its opposite ends with pin holes


128


. Pins


130


are located in the pin holes


128


and first loops


132


at first ends of the springs


122


are mounted on the pins


130


. Second loops


134


at opposite second ends of the springs


122


are mounted on the posts


74


,


96


(see

FIGS. 3 and 4

) of the wedge members


50


,


52


. The springs


122


can exert a tension biasing force on the wedge members of the wedges


14


,


16


to move the wedges towards clamping positions against the respective conductors A, B.




Referring now to

FIGS. 9 and 10

another alternate embodiment will be described. The connector


150


includes a frame


152


, two wedges


154


,


156


and tension springs


158


. The frame


152


has an open center section


160


and two wedge sections


162


,


164


similar to the sections


22


,


24


shown in FIG.


1


. However, the frame


152


does not have spring grooves


46


or guide rails


48


. Instead, the frame


152


has guide grooves


166


which cross each other at the center section


160


. However, in alternate embodiments the grooves


166


might not cross or intersect each other. Referring also to

FIGS. 11A-11C

, the wedge members


168


,


170


of the wedges


154


,


156


are shown. The first wedge member


168


comprises an inner side with a conductor contact surface


172


, an outer side with a spring groove


174


, a bottom side with a guide rail or projection


176


, and two inward projections


178


with a guide slot


180


between the inward projections. The second wedge member


170


comprises an inner side with a conductor contact surface


182


, an outer side with a spring groove


184


, a bottom side with a guide rail or projection


186


, an inward projection


188


, and recesses


190


on opposite sides of the inward projection


188


. Guide rails


176


,


186


are located in the guide grooves


166


to guide movement of the wedge members


154


,


156


on the frame


152


. Inward projections


178


extend into recesses


190


and inward projection


188


extends into recess


180


such that the wedge members of each wedge can slide laterally inward and outward relative to each other, but are interlocked to move with each other in transverse directions. The springs


158


are located in the spring grooves


174


,


184


of the wedge members. The springs


158


have ends


194


,


196


clipped onto the wedge members and frame


152


such that the springs bias the wedges


154


,


156


towards the opposite ends of the frame. The crossing nature of the grooves


166


allow increased range of movement for the wedge members. The paths of the wedges


154


,


156


overlap at center section


160


for alternate positioning at center section


152


. The increase range of movement can provide wider gaps between the conductor contact surfaces


172


,


182


for larger conductors or easier location of the conductors between the surfaces


172


,


182


. The size of the frame can be smaller with this embodiment because of the increased range of movement for the wedges, the overlapping paths of the wedges


154


,


156


, and the springs extending in grooves of the wedges rather than spring grooves of the frame.




Referring now to

FIGS. 12A and 12B

, another alternate embodiment is shown. In this embodiment the connector


200


is substantially identical to the connector


150


shown in

FIG. 9

, but the frame


152


′ includes a pre-latch


202


. The pre-latch


202


includes latch tabs


204


. The tabs


204


are adapted to latch onto the second wedge members


170


to keep the wedges


154


and


156


(not shown in

FIGS. 12A and 12B

) in retracted pre-connection positions. A user can unlatch the tabs


204


from the second wedge members by merely pulling or deflecting the ends


206


outward.




It should be understood that the foregoing description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
