Abstract
Abstract A terminal block for slot connection of insulated conductors, in particular for telecommunication lines, compresses a number of terminals fixed in a flat-shaped holder. Each terminal is bent 180* around a transverse line dividing the terminal into a longer and a shorter part, the longer part being inserted in a through passage of the holder and the shorter part in blind recess. The insulated conductor is connected to a terminal of the terminal block by pressing it into a pair of slots which are running parallelly from a hole in the bent end of the terminal towards the ends of each of the parts. In order to prevent the terminal from sliding in its recesses there is provided an embossed stop in the longer part which stop snaps against a bottom edge of a cut-out in the holder when the terminal has been inserted in the holder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
259 words
A terminal block assemblage comprising: a flat shaped terminal holder of insulating material, said terminal holder being provided with a plurality of pairs of oppositely facing terminal recesses which are separated by insulating material, a first recess of each pair passing completely through said terminal holder to provide a through channel, the second recess of each pair extending only part way through said terminal holder to provide a blind channel, and cut-outs provided in said terminal holder at a first edge thereof and opposite corresponding portions of said recesses whereby portions of said channels are exposed; and a plurality of terminals, each associated with a different one of the pairs of terminal recesses, each of said terminals comprising a flat strip of conductive material bent at least 180* at a bend line perpendicular to the longitudinal axis of the strip to provide a longer leg and a shorter leg, said shorter leg being disposed in said second recess, said longer leg being disposed in said first recess with the end thereof extending beyond a second edge of said terminal holder, the portion of said strip adjacent the bend line being adjacent said first edge of said terminal holder and said cut-outs, an opening means in each of said legs in the region of the bend line and slots in said legs, said slots having a width narrower than said opening means and communicating therewith whereby a conductor can be connected to a terminal by being passed via said cut-outs through said opening means and pressed down into said slots.
Claim 2
Dependent Claim
259 words
A terminal block assemblage comprising: a flat shaped terminal holder of insulating material, said terminal holder being provided with a plurality of pairs of oppositely facing terminal recesses which are separated by insulating material, a first recess of each pair passing completely through said terminal holder to provide a through channel, the second recess of each pair extending only part way through said terminal holder to provide a blind channel, and cut-outs provided in said terminal holder at a first edge thereof and opposite corresponding portions of said recesses whereby portions of said channels are exposed; and a plurality of terminals, each associated with a different one of the pairs of terminal recesses, each of said terminals comprising a flat strip of conductive material bent at least 180* at a bend line perpendicular to the longitudinal axis of the strip to provide a longer leg and a shorter leg, said shorter leg being disposed in said second recess, said longer leg being disposed in said first recess with the end thereof extending beyond a second edge of said terminal holder, the portion of said strip adjacent the bend line being adjacent said first edge of said terminal holder and said cut-outs, an opening means in each of said legs in the region of the bend line and slots in said legs, said slots having a width narrower than said opening means and communicating therewith whereby a conductor can be connected to a terminal by being passed via said cut-outs through said opening means and pressed down into said slots.
Claim 3
Dependent Claim
259 words
A terminal block assemblage comprising: a flat shaped terminal holder of insulating material, said terminal holder being provided with a plurality of pairs of oppositely facing terminal recesses which are separated by insulating material, a first recess of each pair passing completely through said terminal holder to provide a through channel, the second recess of each pair extending only part way through said terminal holder to provide a blind channel, and cut-outs provided in said terminal holder at a first edge thereof and opposite corresponding portions of said recesses whereby portions of said channels are exposed; and a plurality of terminals, each associated with a different one of the pairs of terminal recesses, each of said terminals comprising a flat strip of conductive material bent at least 180* at a bend line perpendicular to the longitudinal axis of the strip to provide a longer leg and a shorter leg, said shorter leg being disposed in said second recess, said longer leg being disposed in said first recess with the end thereof extending beyond a second edge of said terminal holder, the portion of said strip adjacent the bend line being adjacent said first edge of said terminal holder and said cut-outs, an opening means in each of said legs in the region of the bend line and slots in said legs, said slots having a width narrower than said opening means and communicating therewith whereby a conductor can be connected to a terminal by being passed via said cut-outs through said opening means and pressed down into said slots.
Claim 4
Dependent Claim
259 words
A terminal block assemblage comprising: a flat shaped terminal holder of insulating material, said terminal holder being provided with a plurality of pairs of oppositely facing terminal recesses which are separated by insulating material, a first recess of each pair passing completely through said terminal holder to provide a through channel, the second recess of each pair extending only part way through said terminal holder to provide a blind channel, and cut-outs provided in said terminal holder at a first edge thereof and opposite corresponding portions of said recesses whereby portions of said channels are exposed; and a plurality of terminals, each associated with a different one of the pairs of terminal recesses, each of said terminals comprising a flat strip of conductive material bent at least 180* at a bend line perpendicular to the longitudinal axis of the strip to provide a longer leg and a shorter leg, said shorter leg being disposed in said second recess, said longer leg being disposed in said first recess with the end thereof extending beyond a second edge of said terminal holder, the portion of said strip adjacent the bend line being adjacent said first edge of said terminal holder and said cut-outs, an opening means in each of said legs in the region of the bend line and slots in said legs, said slots having a width narrower than said opening means and communicating therewith whereby a conductor can be connected to a terminal by being passed via said cut-outs through said opening means and pressed down into said slots.
Claim 5
Dependent Claim
23 words
The terminal block assemblage of claim 1 wherein the slots of each of said terminals are opposite each other and have different widths.
Claim 6
Dependent Claim
60 words
The terminal block assemblage of claim 1 wherein further cut-outs are provided at said second edge of said terminal holder for exposing a portion of each of said first recesses, and wherein said longer legs are provided with ramplike bosses for providing removal stops against the associated further cut-outs after a terminal has been inserted in a pair of recesses.
