Abstract
Abstract A novel electrical connector comprises a slotted metallic contact disposed within a movable contact support preferably frangibly coupled to a cover portion adapted to lockingly mate with a base portion having partitioned wire receiving channels. To effect a connection, wires are inserted within the base portion wire receiving channels, the cover portion is lockingly snapped into place over the base portion, and the contact support then depressed inwardly causing the slotted metallic contact to engage the conductors to provide an interconnection therebetween in one safe, simple, and rapid operation. Frangible wall segments may be provided to permit the conductor to be inserted into the connector either from one or both sides of the wire receiving channel. Inspection ports may be provided to view the disposition of the conductors within the connector wire receiving channels during and after assembly. The channel partitions may be further provided with toothed portions to provide a restraint for the conductors engaged therebetween.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
208 words
An electrical connector comprising: a base portion having wire receiving channels extending therewithin, and partitions selectively spaced from one another to define said wire receiving channels; a cover portion adapted to mate with and overlie said base portion, said cover portion having a selectively formed aperture extending generally transversely therethrough; means for locking said cover portion to said base portion; contact support means selectively movable from a first position to a second position transversely within said cover portion aperture and disposed in said cover portion in said first position generally adjacent said cover portion aperture; and slotted metallic contact means fixedly disposed within said contact support means and movable therewith, said contact means being aligned to intersect said wire receiving channels when said contact support portion is depressed within said cover portion aperture and moved from said first position to said second position after said cover portion is disposed in selective overlying relationship with said base portion, whereby upon the selective placement of conductors within said base portion wire receiving channels, and the depression of said contact support means, said contact means is caused to engage such conductors to provide a connection therebetween, said connector further comprising frangible segments connecting said contact support means to said cover portion.
Claim 2
Dependent Claim
208 words
An electrical connector comprising: a base portion having wire receiving channels extending therewithin, and partitions selectively spaced from one another to define said wire receiving channels; a cover portion adapted to mate with and overlie said base portion, said cover portion having a selectively formed aperture extending generally transversely therethrough; means for locking said cover portion to said base portion; contact support means selectively movable from a first position to a second position transversely within said cover portion aperture and disposed in said cover portion in said first position generally adjacent said cover portion aperture; and slotted metallic contact means fixedly disposed within said contact support means and movable therewith, said contact means being aligned to intersect said wire receiving channels when said contact support portion is depressed within said cover portion aperture and moved from said first position to said second position after said cover portion is disposed in selective overlying relationship with said base portion, whereby upon the selective placement of conductors within said base portion wire receiving channels, and the depression of said contact support means, said contact means is caused to engage such conductors to provide a connection therebetween, said connector further comprising frangible segments connecting said contact support means to said cover portion.
Claim 3
Dependent Claim
52 words
An electrical connector as defined in claim 1 wherein said partitions further comprise toothed portions having an inclined first surface communicating with a second surface thereof at a sharp edge to define a wedge shaped protusion adapted to provide unidirectional restraining means for conductors disposed within said base portion wire receiving channels.
Claim 4
Dependent Claim
19 words
An electrical connector as defined in claim 1 wherein said cover portion is hingedly coupled to said base portion.
Claim 5
Dependent Claim
60 words
An electrical connector as defined in claim 1 wherein said base portion further comprises wall segments each aligned with a respective one of said wire receiving channels, each of said wall segments having opposed edges frangibly connected to said base portion to permit selective displacement therefrom to provide access to at least one end of an associated wire receiving channel.
Claim 6
Dependent Claim
41 words
An electrical connector as defined in claim 1 wherein said cover portion further comprises at least one seleced area of reduced thickness arranged to provide a generally translucent inspection port for viewing the disposition of conductors disposed within said electrical connector.
Claim 7
Dependent Claim
22 words
An electrical connector as defined in claim 1 wherein said base portion and said cover portion are formed from electrically insulating material.
Claim 8
Dependent Claim
69 words
An electrical connector as defined in claim 1 wherein said contact means comprises pairs of selectively spaced blade members, said contact means having slots separating adjacent pairs of said blade members, said slots extending longitudinally between adjacent blade members from the free ends thereof a first given distance at first given width and then a second given distance at a second given width less than said first given width.
Claim 9
Dependent Claim
66 words
An electrical connector as defined in claim 1 wherein said base portion further comprises an internal recessed portion coicident with said contact means to permit a section of a conductor engaged by said contact means to be depressed thereinto upon the displacement of said contact support means from said first position to said second position as said cover portion is cooperatively engaged with said base portion.
Claim 10
Dependent Claim
38 words
An electrical connector as defined in claim 8 wherein said recessed portion further comprises an inner surface having raised portions thereon, said raised portions being aligned in general coincidence with the slotted portions of said slotted contact means.
Claim 11
Dependent Claim
23 words
An electrical connector as defined in claim 1 wherein said wire receiving channels extend radially inwardly from the periphery of said base portion.
Claim 12
Dependent Claim
28 words
An electrical connector as defined in claim 10 further comprising stop means located generally centrally within said base portion for limiting the extent of insertion of conductors therewithin.
