Abstract

A connector is provided having a shaft member and a wire substrate. The wire substrate is wound helically on a surface of the shaft member. The wire substrate includes a band-shaped base material, a plurality of conductive wires provided on one surface of the base material, and a plurality of contact pads provided on another surface of the base material. Each of the conductive wires is connected to each of the contact pads, and the contact pads are exposed on an outside of the wire substrate aligned so as to open a gap in a length direction of the shaft member, in a state where the wire substrate is wound helically on the surface of the shaft member.

First claim

The invention claimed is:

1. A connector comprising:
a shaft member having an outer cylindrical surface; and
a wire substrate having a band-shaped base material, a plurality of conductive wires provided on a first surface of the base material, and a plurality of contact pads provided on a second, opposite surface of the base material, each conductive wire being connected to a respective one of the contact pads,
wherein the wire substrate is wound helically onto the outer cylindrical surface of the shaft member such that the first surface of the base material faces the outer cylindrical surface of the shaft member and such that the second surface of the base material is exposed,
wherein, where the wire substrate has been wound helically onto a length of the outer cylindrical surface of the shaft member, the wire substrate covers an entirety of the length of the outer cylindrical surface of the shaft member such that the entirety of the length of the outer cylindrical surface of the shaft member is not exposed; and
wherein the contact pads are exposed and separated from one another in a length direction of the shaft member.

2. The connector according to claim 1 , wherein the base material has a first margin on a first width direction end and a second margin on a second width direction end, neither the conductive wires nor the contact pads being present in either of the first or second margins, and wherein the first margin of a first winding of the wire substrate at least partially overlaps the second margin of a second winding of the wire substrate, where the first winding and the second winding are adjacent to one another.

3. The connector according to claim 1 , wherein each of the contact pads are also formed connected in a length direction of the wire substrate and are exposed on the outside of the wire substrate over a predetermined length with respect to the length direction of the shaft member.

4. The connector according to claim 1 , wherein each of the contact pads is formed split into a plurality of pad parts, where the pad parts form a long thin row longitudinal to the shaft member.

5. The connector according to claim 1 , wherein the wire substrate has a main body part and a free end, the main body part being wound helically on the outer surface of the shaft member, the free end not being wound helically onto the outer surface of the shaft member, wherein the free end has a plurality of electric wire connecting pads configured to be connected, respectively, to a terminus of a respective electric wire of a cable, and wherein each electric wire connecting pad is connected to a respective one of the conductive wires.

6. The connector according to claim 5 , wherein a length direction of the free end is inclined with respect to a length direction of the main body and parallel to the length direction of the shaft member, where the free end includes a narrow part and a folding part that is wider than the narrow part, and the folding part matches a slit extending the length direction and is folded using the slit as a fold.

7. The connector according to claim 6 , wherein several of the conductive wires are provided in the narrow part on the first surface of the base material while other conductive wires are provided on the second surface of the base material, and all of the conductive wires and electric wire connecting pads are provided in the folding part on the second surface of the base material.
