Abstract
Abstract A terminal (20) lies, together with an insulated electric wire (8) having a superposed relation therewith, between a bottom of a groove (13) of a first member (11) and a vertex face (15) of a protrusion (14) of a second member (12), and is subjected together with the insulated electric wire (8) to a sequence of ultrasonic vibrations under pressures exerted via the first and second members (11,12) so that an insulation of the insulated electric wire is melted and the terminal is current-conductively contacted to a core wire of the insulated electric wire, wherein the terminal has at a connection part (21) thereof to be connected to the insulated electric wire an engaging portion (22) engageable with a side face of the protrusion (14) having an engagement portion to be engaged therewith.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
A terminal ultrasonically connected to an insulated electric wire having a superposed relation therewith between a bottom of a groove of a first member and a vertex face of a protrusion of a second member, wherein the terminal is subjected together with the insulated electric wire to a sequence of ultrasonic vibrations under pressures exerted by the first and second members so that an insulation of the insulated electric wire is melted and the terminal is current-conductively contacted to a core wire of the insulated electric wire, and wherein the terminal, comprises: a connection portion to be connected to the insulated electric wire; and an engaging portion engageable with a side face of the protrusion.
Claim 2
Dependent Claim
115 words
A terminal ultrasonically connected to an insulated electric wire having a superposed relation therewith between a bottom of a groove of a first member and a vertex face of a protrusion of a second member, wherein the terminal is subjected together with the insulated electric wire to a sequence of ultrasonic vibrations under pressures exerted by the first and second members so that an insulation of the insulated electric wire is melted and the terminal is current-conductively contacted to a core wire of the insulated electric wire, and wherein the terminal, comprises: a connection portion to be connected to the insulated electric wire; and an engaging portion engageable with a side face of the protrusion.
Claim 3
Dependent Claim
67 words
A terminal for an ultrasonic connection according to claim 1, wherein: the connection portion to be connected to the insulated electric wire comprises a bottom wall for the insulated electric wire to placed thereon and a pair of vertical walls standing at both sides of the bottom wall; and the engaging portion comprises a pair of engaging pawls cut in the vertical walls and inwardly raised therefrom.
Claim 4
Dependent Claim
64 words
A terminal for an ultrasonic connection according to claim 1, wherein: the connection portion to be connected to the insulated electric wire comprises a bottom wall for the insulated electric wire to be placed thereon and a pair of engaging pieces standing at both sides of the bottom wall; and the engaging portion comprises a pair of engaging pawls having inwardly folded free ends.
Claim 5
Dependent Claim
129 words
An ultrasonic connection structure, comprising: a terminal according to claim 1 connected to an insulated electric wire having a superposed relation therewith by way of an ultrasonic connection between a bottom of a groove of a first member and a vertex face of a protrusion of a second member; wherein the terminal is subjected together with the insulated electric wire to a sequence of ultrasonic vibrations under pressures exerted by the first and second members so that an insulation of the insulated electric wire is melted and the terminal is current-conductively contacted to a core wire of the insulated electric wire; and wherein the terminal has a connection portion to be connected to the insulated electric wire and an engaging portion engageable with a side face of the protrusion.
Claim 6
Dependent Claim
122 words
An ultrasonic connection structure, comprising: a first member having a groove therein; a second member having a protrusion; and a terminal having a connection part connected to an insulated wire having a superposed relation therewith, and an engaging portion engageable with a side face of the protrusion; wherein the terminal and insulated wire are positioned between a bottom of the groove of the first member and a vertex face of the protrusion of the second member; and wherein the terminal and insulated wire are subjected to a sequence of ultrasonic vibrations under pressure exerted by the first and second members so that an insulation of the insulated wire is melted and the terminal conductively contacts a core wire of the insulated wire.
Claim 7
Dependent Claim
122 words
An ultrasonic connection structure, comprising: a first member having a groove therein; a second member having a protrusion; and a terminal having a connection part connected to an insulated wire having a superposed relation therewith, and an engaging portion engageable with a side face of the protrusion; wherein the terminal and insulated wire are positioned between a bottom of the groove of the first member and a vertex face of the protrusion of the second member; and wherein the terminal and insulated wire are subjected to a sequence of ultrasonic vibrations under pressure exerted by the first and second members so that an insulation of the insulated wire is melted and the terminal conductively contacts a core wire of the insulated wire.
