Abstract

A cable assembly includes a first bonding member formed of a thermoplastic resin and configured to couple an insulation and a connector housing to suppress movement of the flat cable relative to the connector. The connector housing includes a mounting surface on which the flat cable is mounted. The first bonding member includes a first portion provided inside the contour of the insulation when viewed from the first direction substantially perpendicular to the mounting surface, and a second portion extending from the first portion and provided outside the contour when viewed from the first direction. The first portion has a first projected area defined inside the contour when viewed from the first direction. The second portion has a second projected area defined outside the contour when viewed from the first direction. The first projected area is larger than the second projected area.

Claims23

Dependent claims

A cable assembly comprising:

a connector comprising:
at least two bus bars each having electrical conductivity;
and
a connector housing partially covering the at least two bus bars to insulate the at least two bars from each other;
a flat cable comprising:
at least two core wires each having electrical conductivity and electrically connected to the at least two bus bars, respectively;
and
an insulation partially covering the at least two core wires;
a first bonding member, which is formed of a thermoplastic resin, configured to couple the insulation and the connector housing to suppress movement of the flat cable relative to the connector;
the connector housing including a mounting surface on which the flat cable is mounted;
the first bonding member comprising:
a first portion provided inside a contour of the insulation when viewed from a first direction substantially perpendicular to the mounting surface;
and
a second portion extending from the first portion and provided outside the contour when viewed from the first direction;
the first portion having a first projected area defined inside the contour when viewed in the first direction;
the second portion having a second projected area defined outside the contour when viewed in the first direction;
and
the first projected area being larger than the second projected area.

A cable assembly manufacturing method comprising:

providing a flat cable including at least two core wires having conductivity, and an insulation having electrical insulation properties and partially covering the at least two core wires;
providing a connector including at least two bus bars having conductivity, and a connector housing having electrical insulation properties and partially covering the at least two bus bars;
providing a first protrusion made of a thermoplastic material on a mounting surface of the connector housing;
disposing a flat cable on the mounting surface so as to abut against the first protrusion;
melting the thermoplastic material by abutting a heating body against the first protrusion, and providing the thermoplastic material on the insulation;
solidifying the molten thermoplastic material to fix the flat cable to the mounting surface;
and
electrically connecting the exposed portions of the at least two core wires exposed from the insulation to the at least two bus bars, respectively.

A cable assembly manufacturing method comprising:

providing a flat cable including at least two core wires having electrical conductivity and an insulation having electrical insulation properties and partially covering the at least two core wires;
providing a base having a mounting surface;
providing a first protrusion made of a thermoplastic material on the mounting surface;
disposing the flat cables on the mounting surface to abut against the first protrusion;
melting the thermoplastic material by abutting a heating body against the first protrusion while moving the heating body in a first direction substantially perpendicular to the mounting surface, and providing the melted thermoplastic material on the insulation;
solidifying the melted thermoplastic material to fix the flat cable to the mounting surface;
and
abutting the heating body against the first protrusion such that, when the heating body is viewed in the first direction in a state where the flat cable is disposed on the mounting surface in contact with the first protrusion, a first region of the first protrusion overlapping the heating body is surrounded by a second region of the first protrusion not overlapping the heating body and a region occupied by the flat cable.
