Abstract

A cable with a molded resin includes a cable including an electric wire and a sheath covering the electric wire, the electric wire including a central conductor and an insulation covering the central conductor, and a molded resin covering a part of the electric wire protruding from the sheath in a longitudinal direction thereof, the molded resin being apart from the sheath. The electric wire is bent at not less than one bent part in the molded resin.

First claim

What is claimed is:

1. A cable with a molded resin, comprising:
a cable comprising electric wires and a sheath covering the electric-wires, each electric wire comprising a central conductor and an insulation covering the central conductor;
a molded resin covering parallel portions of the electric wires protruding from the sheath in a longitudinal direction thereof, the molded resin being apart from the sheath; and
a sensor connected to an end part of the electric wires in the molded resin,
wherein the sensor comprises a measurement part with an element to detect magnetism mounted thereon and a lead terminal disposed at the measurement part,
wherein the central conductor is connected to the lead terminal,
wherein the electric wires are bent at the parallel portions in the molded resin,
wherein said each electric wire meanders within the molded resin so as to be bent at three or more bent parts,
wherein each bent part is disposed within the molded resin,
wherein each said bent part is bent at an angle of 45 degrees to 90 degrees,
wherein said each electric wire comprises a derivation part derived from the molded resin and an extension part extending in a direction intersected with a derivation direction of the derivation part,
wherein the electric wires are parallel with each other along an entire length within the molded resin, and
wherein each said electric wire includes an exposed wire segment portion disposed between said sheath and said molded resin.

2. The cable according to claim 1 ,
wherein the extension part is disposed in the molded resin such that a bent part falls between the derivation part and the extension part.

3. The cable according to claim 2 , wherein the extension part extends in a direction intersected at an angle of 45 degrees to 90 degrees with the derivation direction.

4. The cable according to claim 1 , wherein the molded resin comprises one of nylon, polyamide and polybutylene terephthalate (PBT).

5. The cable according to claim 4 , wherein the molded resin further comprises a glass fiber.

6. The cable according to claim 1 , wherein the electric wires are arranged apart from each other in the molded resin.

7. The cable according to claim 1 , wherein the electric wires are arranged apart from each other in the molded resin.

8. The cable according to claim 1 , wherein the molded resin covers the insulation and the central conductor exposed from the insulation.

9. The cable according to claim 1 , wherein the molded resin covers the insulation and the central conductor exposed from the insulation in a part of the electric wires protruding from the sheath.

10. The cable according to claim 1 , wherein a distal end of said each electric wire extends in parallel with a derivation direction of said each electric wire derived from the molded resin.

11. The cable according to claim 10 , wherein said each electric wire comprises a derivation part derived from the molded resin in the derivation direction, and an extension part extending in a direction intersected with the derivation direction of the derivation part.

12. The cable according to claim 1 , further comprising a sensor connected to the electric wires, the sensor being exposed to outside without being covered by the molded resin.

13. The cable according to claim 1 , wherein, in a side view of the cable, an entirety of one of the electric wires overlaps with an entirety of another one of the electric wires.

14. The cable according to claim 1 , wherein the electric wires are bent at bent portions that are arranged in parallel with each other when viewed from a first direction, and are bent when viewed from a second direction orthogonal to the first direction.

15. The cable according to claim 14 , wherein the first direction includes a top view of the cable, and the second direction includes a side view of the cable.
