A connector includes a first insulator having a protrusion portion formed on a first retaining surface, a second insulator having a recess portion formed at a second retaining surface, and a spring member retained in one of the first insulator and the second insulator, the spring member being disposed between the protrusion portion and the recess portion and has a pressing portion that is elastically displaceable in a first direction, a sheet type conductive member and an electric wire being sandwiched between the first retaining surface and the second retaining surface, at least a part of the protrusion portion being accommodated in the recess portion, a conductor portion of the electric wire and a flexible conductor of the sheet type conductive member being pressed against each other in the first direction by the pressing portion within the recess portion.

[Problems] A cable connecting structure for connecting bus bars and an insulating part with a simple configuration is provided. [Means for solving the problems] The cable connecting structure includes a plurality of bus bars (60), a flexible flat cable (14), and an insulating part (40). The flexible flat cable (14) is connected to the bus bars (60). The insulating part (40) has bus bar mounting grooves (41) for arranging the bus bars (60) individually and a bus bar fixing portion (45) for fixing the bus bars (60) by overlapping the bus bars (60). A triangular protrusion (62) that protrudes toward a side where the flexible flat cable (14) is mounted is formed in each of the bus bars (60). The flexible flat cable (14) is connected to the triangular protrusion (62) in each of the bus bars (60).

A cable connection structure includes a round cable, a flat cable, a holder holding an end portion of the round cable and an end portion of the flat cable and pulling out the round cable and the flat cable to overlap each other in a same direction, a connecting portion in which a core wire exposed from the end portion of the round cable and a conductor exposed from the end portion of the flat cable held by the holder are connected to each other, and a mold resin portion collectively covering the outer circumference of the holder and the outer circumference of the round cable and the flat cable pulled out from the holder.

A connector assembly includes a sheet type conductive member having a flexible conductor, an electric wire and a connector, the connector having a first insulator with a first retaining surface and a second insulator with a second retaining surface, the sheet type conductive member having a first sheet portion with a retained portion, a second sheet portion joined to the retained portion via a folding-back line and disposed to face the second retaining surface with the second sheet portion being folded back onto the retained portion along the folding-back line, and at least one electric wire inserting hole penetrating the sheet type conductive member, the conductor portion of the electric wire being passed through the electric wire inserting hole and disposed between the retained portion and the second sheet portion.

A conductive path includes: a first conductor in which a terminal end portion serves as a first connection portion; a second conductor in which a second connection portion at a terminal end portion is coaxially fixed to the first connection portion; a support member that is more rigid than the first and second conductors, and is disposed so as to extend along a fixed portion between the first and second connection portions; and a heat-shrinkable tube (holding member) that integrates the support member with the first and second conductors while enveloping the support member. Even when an external force acts on the first and second conductors so as to skew the axes of the two conductors, the support member and the heat-shrinkable tube keep the two conductors in the coaxial state.

A connector includes a housing accommodating an end of the connection object and an end of the electric wire, the connection object and the conductor portion of the electric wire making contact with and being electrically connected to each other in the housing, the housing having an electric wire lead-out port leading out the electric wire from inside to outside of the housing, the electric wire lead-out port having a first contact portion and a second contact portion that make contact with the electric wire at two positions separate away from each other along a length direction of the electric wire so as to disperse a load applied to the electric wire when the electric wire is led out from the housing at a predetermined minimum bending radius determined by a shape of the housing around the electric wire lead-out port.

An implantable medical device can include a housing including electronic devices within the housing; a header attached to the housing and including one or more bores; and a feedthrough assembly between the housing and the header; wherein the electronic devices include a PCB electronically connected to the header by a feedthrough wire running from the feedthrough assembly to the PCB, wherein the feedthrough wire is connected to the PCB with a pigtail spring connector.
