Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A terminal block which comprises: a moled base including a bottom member, a set of barriers rising from the bottom member and spaced apart to define a plurality of channels, a surface which is recessed from the bottom member to form a cavity, a plurality of pedestals each formed in a respective channel above the cavity, one pedestal having an aperture therethrough which communicates with the cavity; a plurality of wire terminal units, each disposed on a respective pedestal; and a molded insert fastened to the base to hold the wire terminal units in position, the insert including a strip which is disposed longitudinally across the barriers, a plurality of integrally formed retaining members disposed below the strip and located to hold the terminal units in position; and an integrally formed fastening member depending from one of the retaining members and through the pedestal aperture, the fastening member having a portion that is adapted to be secured in the cavity of the base.
Claim 2
Dependent Claim
163 words
A terminal block which comprises: a moled base including a bottom member, a set of barriers rising from the bottom member and spaced apart to define a plurality of channels, a surface which is recessed from the bottom member to form a cavity, a plurality of pedestals each formed in a respective channel above the cavity, one pedestal having an aperture therethrough which communicates with the cavity; a plurality of wire terminal units, each disposed on a respective pedestal; and a molded insert fastened to the base to hold the wire terminal units in position, the insert including a strip which is disposed longitudinally across the barriers, a plurality of integrally formed retaining members disposed below the strip and located to hold the terminal units in position; and an integrally formed fastening member depending from one of the retaining members and through the pedestal aperture, the fastening member having a portion that is adapted to be secured in the cavity of the base.
Claim 3
Dependent Claim
40 words
The terminal block of claim 1, wherein the fastening member has a detent formed on its distal end, the fastening member being slidable into the aperture in the base until the detent reaches the cavity and engages the recessed surface.
Claim 4
Dependent Claim
76 words
The terminal block of claim 2, wherein: the barriers each have a top edge including a notch; wherein the insert strip is received in the notches in the barriers, the strip having a top surface which fits flush with the top edges of the barriers; and wherein the retaining members are divided by gaps formed therebetween, the retaining members sliding into the channels of the base and the gaps receiving the top edges of the barriers.
Claim 5
Dependent Claim
41 words
The terminal block of claim 3, wherein a grooved member is integrally formed on one of the barriers, the grooved member extending upward toward the top edge of the barrier to receive an edge formed on one of the retaining members.
Claim 6
Dependent Claim
109 words
The terminal block of claim 4, wherein: the wire terminal units each include a connector strap having a notch, a pair of clamping members, and a pair of screws, each screw extending through one of the clamping members and the strap to form a wire terminal; and wherein the pedestals include a top sufface for supporting a wire terminal unit, the surface having two positioning holes formed therein and a raised locator surface which together form a seat for a wire terminal unit, the extended end of each screw being received in one of the positioning holes, and the locator surface being received in the notch of the strap.
