Claims
- 1. An electrical terminal adapted to grip opposite side margins of an elongated flat configuration conductor, the terminal comprising:
- a web portion,
- a first pair of teeth extending from said web portion of the conductor for inwardly deforming one side margin of the conductor in two places along the length of the conductor,
- a second pair of teeth extending from said web portion, for inwardly deforming another side margin of the conductor in two places along the length of the conductor,
- said first pair of teeth defining a clearance therebetween for receiving therein a portion of one side margin of the conductor which lies between the inwardly deformed two places of the conductor,
- said second pair of teeth defining a clearance therebetween for receiving therein a portion of another side margin of the conductor which lies between the inwardly deformed two places of the conductor,
- said teeth of each pair being deformable toward said web to pinch said conductor against said web,
- said first pair of teeth being offset from said second pair of teeth longitudinally along the length of the web, with at least one of the teeth of each pair disposed across said web opposite the clearances between the teeth of the opposite pair so at least one of the teeth of each pair will pinch the conductor against said web and thereby tend to press the conductor into wedged relationship into the clearance between the teeth of the opposite pair.
- 2. The connection as recited in claim 1, and further wherein, said teeth penetrate the insulation jacket at the inwardly pinched and deformed portions of the conductor side margins to establish electrical contact of the teeth with said side margins, and the edge surfaces of adjacent teeth of each pair being sharp and penetrating through the insulation jacket and in electrical contact with the portions of the side margins which are wedged between the adjacent teeth.
- 3. The connection as recited in claim 1, wherein the adjacent teeth of each pair are substantially tapered to define a tapered clearance therebetween with portions of the conductor side margins wedged into each of the tapered clearances between adjacent teeth, and with said teeth having sharp edges facing the clearances between the adjacent teeth which penetrate the insulation jacket on said conductor portions that are wedged into said clearances to establish electrical contact therewith.
- 4. A terminal for connection to a conductor of elongated and flat configuration, comprising:
- a web portion,
- each side of said web portion provided with a pair of projecting teeth which are bent outwardly from said body portion to define two rows of teeth,
- each pair of teeth defining therebetween a progressively narrowing notch for wedged receipt therein of a side margin of a conductor of elongated and flat configuration,
- the pair of teeth on one side of the web being offset with respect to the teeth on the other side of the web, with the notches between each pair of teeth thereby being offset from each other,
- the first pair of teeth being initially spaced from the other pair of teeth by a width less than the width than the conductor to which the terminal is to be attached to permit forcible insertion of the conductor initially into said clearance while portions of the side margins of the conductor are inwardly pinched adjacent each of said teeth,
- said teeth being deformable toward the teeth of the opposite pair and then toward the base to force the tips of said teeth into engagement on the conductor pinching the conductor against the web portion and to force the side margins of the conductor into the progressively narrow notches, the edges of said teeth adjacent said notches being substantially sharpened to penetrate the insulation jacket on the conductor and to establish electrical contact with the conductor.
- 5. An electrical terminal intended for electrical connection to an elongated conductor of the type having a flat configuration and two longitudinal side margins extending the length of the conductor, said terminal comprising:
- a web portion having a first pair of teeth projecting from one side of the web portion, and a second pair of teeth projecting from an opposite side of the web portion,
- each pair of teeth being bent out of plane of the web portion to define a space initially separating the first pair of teeth from the other pair of teeth, said space being initially less than the width between the longitudinal side margins of the conductor to which the terminal is to be connected such that upon forcible insertion of the conductor into said space, portions of the conductor side margins at corresponding locations immediately adjacent the teeth become pinched inwardly toward the longitudinal center axis of the conductor while substantially unpinched portions of the conductor side margin are forcibly wedged between the teeth of each pair, and
- subsequent to insertion of the conductor into the space between the opposed pairs of teeth said teeth being capable of deformation toward the teeth of the opposite pair and then toward said web portion to pinch the conductor against the web portion, the free ends of the teeth being sharpened for penetrating through the insulation jacket of the conductor to establish electrical contact between the teeth of the terminal and the conductor,
- the teeth of each pair having sharpened edges for piercing through the insulation jacket of the conductor to establish electrical contact of the teeth of each pair with the conductor side margin portions which are forcibly wedged between the teeth of each pair.
- 6. The structure as recited in claim 5, wherein the adjacent teeth of each pair are tapered to define therebetween a converging wedge-shaped clearance into which said substantially unpinched conductor side margins are forcibly wedged.
- 7. An electrical terminal intended for electrical connection to an elongated conductor of the type having a flat configuration and longitudinal side margins extending the length of the conductor, the terminal comprising:
- a web,
- a first pair of teeth projecting from one side of the web and defining a clearance between the first pair of teeth,
- a second pair of teeth projecting from a second side of the web with the second pair of teeth defining therebetween a second clearance,
- each pair of teeth being deformable into curled relationship over said web to grip the conductor between said web and each of said teeth,
- each pair of teeth being deformable into curled relationship over the side margins of said conductor to inwardly deform corresponding portions of said side margins of the conductor and to outwardly buckle said conductor side margins into the clearance defined between said each pair of teeth, and
- said teeth further being deformable toward said base to penetrate the teeth into the insulation jacket of the conductor to establish electrical contact between the conductor and the teeth and further to pinch the conductor against said base and compressibly pinch the teeth onto the curled over side margins of the conductor and to force the outwardly buckled portions of the conductor into the clearances between the pairs of teeth.
- 8. An electrical terminal adapted to be connected in gripped relationship with a flat elongated conductor, comprising:
- a web portion having a first pair of teeth projecting from one side of said web portion and a second pair of teeth projecting from an opposite side of said web portion,
- each of said pairs of teeth being bent outwardly of the plane of said web portion and defining an initial space separating said first and second pairs of teeth,
- each of said teeth being wedge-shaped and defining wedged-shaped clearances between adjacent teeth,
- each of said teeth having sharp slicing edges adjacent corresponding wedge-shaped clearances,
- each of said teeth having a rounded and sharpened tip, and
- each of said teeth being chamfered to allow curling thereof upon deflection of said teeth tips toward said web portion pinching a flat elongated conductor between said teeth tips and said web portion.
- 9. The structure as recited in claim 8, and further wherein, said web portion includes a raised embossment portion against which a flat elongated conductor is pinched by said teeth.
- 10. The structure as recited in claim 9, and further wherein, said web portion includes a channel in alignment with each of said teeth with sharp corners of said web defining each channel.
- 11. The structure as recited in claim 10, wherein, said teeth of said first pair are offset longitudinally with respect to said teeth of said second pair.
