Abstract

Herein disclosed is a connection structure including a waterproof sheet disposed in an inner surface of a wire connection section and has an opening section in a position corresponding to a conductor exposed section, in which the waterproof sheet is configured such that a front end of the waterproof sheet is positioned on a front side from a front end of a conductor crimp section and a rear end of the waterproof sheet is positioned on a rear side from a rear end of the cover crimp section.

First claim

What is claimed is:

1. A connection structure of a crimp terminal with respect to a wire including:
the wire that has a conductor and a cover that covers the conductor; and
a crimp terminal of which an electrical connection section that is electrically connected to a counterpart terminal is formed in a front portion and a wire connection section that is crimped onto an end portion of the wire is formed in a rear portion,
in which the wire connection section has a conductor crimp section that is crimped onto a conductor exposed section in which a conductor is exposed by removing the cover of the end portion of the wire and a cover crimp section that is crimped onto a part of the cover remained in the end portion of the wire, and the conductor crimp section is formed on the front side and the cover crimp section is formed on the rear side,
in which the wire connection section of a state being crimped onto the end portion of the wire covers from a portion on a front side from the front end of the conductor exposed section to a portion on a rear side from a front end of a part of the cover,
in which the connection structure further includes a waterproof sheet that is disposed in an inner surface of the wire connection section and has an opening section in a position corresponding to the conductor exposed section,
in which the wire connection section of a state being crimped onto the end portion of the wire is configured such that the conductor crimp section and the conductor exposed section are electrically connected to each other through the opening section formed in the waterproof sheet, the front end of the waterproof sheet protrudes from a front end of the conductor crimp section to an outside of the conductor crimp section, and front and rear portions of a connection portion between the conductor crimp section and the conductor exposed section are closed by the waterproof sheet.

2. The connection structure of a crimp terminal with respect to a wire according to claim 1 ,
in which the waterproof sheet is attached to the inner surface of the wire connection section by an adhesive layer provided on a surface of a base sheet.

3. The connection structure of a crimp terminal with respect to a wire according to claim 1 ,
in which an adhesive layer is provided in a surface with which the wire comes into contact in the waterproof sheet.

4. The connection structure of a crimp terminal with respect to a wire according to claim 1 ,
in which a rear end of the waterproof sheet protrudes from a rear end of the conductor crimp section.

5. A connection structure of a crimp terminal with respect to a wire including:
the wire that has a conductor and a cover that covers the conductor; and
a crimp terminal of which an electrical connection section that is electrically connected to a counterpart terminal is formed in a front portion and a wire connection section that is crimped onto an end portion of the wire is formed in a rear portion,
in which the wire connection section has a conductor crimp section that is crimped onto a conductor exposed section in which a conductor is exposed by removing the cover of the end portion of the wire and a cover crimp section that is crimped onto a part of the cover remained in the end portion of the wire, and the conductor crimp section is formed on the front side and the cover crimp section is formed on the rear side,
in which the wire connection section of a state being crimped onto the end portion of the wire covers from a portion on a front side from the front end of the conductor exposed section to a portion on a rear side from a front end of a part of the cover,
in which the connection structure further includes a waterproof sheet that is disposed in an inner surface of the wire connection section and has an opening section in a position corresponding to the conductor exposed section,
in which the waterproof sheet is configured such that a front end of the waterproof sheet is positioned on the front side from the front end of the conductor exposed section,
in which a protruded strip is formed in the conductor crimp section along an inner peripheral surface having a U shape; and
in which the wire connection section of a state being crimped onto the end portion of the wire is configured such that the protruded strip is positioned between the front end of the waterproof sheet and the front end of the conductor exposed section, the conductor crimp section and the conductor exposed section are electrically connected to each other through the opening section formed in the waterproof sheet, and front and rear portions of a connection portion between the conductor crimp section and the conductor exposed section are closed by the waterproof sheet.

6. The connection structure of a crimp terminal with respect to a wire according to claim 5 ,
in which the waterproof sheet is configured such that the front end of the waterproof sheet is positioned on the front side from the front end of the conductor crimp section and the rear end of the waterproof sheet is positioned on the rear side from the rear end of the cover crimp section.

7. The connection structure of a crimp terminal with respect to a wire according to claim 5 ,
in which the protruded strip is positioned on a rear end side from the front end of the conductor crimp section.

8. A connection structure of a crimp terminal with respect to a wire including:
the wire that has a conductor and a cover that covers the conductor; and
a crimp terminal of which an electrical connection section that is electrically connected to a counterpart terminal is formed in a front portion and a wire connection section that is crimped onto an end portion of the wire is formed in a rear portion,
in which the wire connection section has a conductor crimp section that is crimped onto a conductor exposed section in which a conductor is exposed by removing the cover of the end portion of the wire and a cover crimp section that is crimped onto a part of the cover remained in the end portion of the wire, and the conductor crimp section is formed on the front side and the cover crimp section is formed on the rear side,
in which the wire connection section of a state being crimped onto the end portion of the wire covers from a portion on a front side from the front end of the conductor exposed section to a portion on a rear side from a front end of a part of the cover,
in which the connection structure further includes a waterproof sheet that is disposed in an inner surface of the wire connection section and has an opening section in a position corresponding to the conductor exposed section,
in which the waterproof sheet is configured such that a front end of the waterproof sheet is positioned on the front side from the front end of the conductor exposed section,
in which a confirmation window is provided in the wire connection section for visibly confirming the waterproof sheet positioned inside thereof from outside of the wire connection section, and
in which the wire connection section of a state being crimped onto the end portion of the wire is configured such that the conductor crimp section and the conductor exposed section are electrically connected to each other through the opening section formed in the waterproof sheet, and front and rear portions of a connection portion between the conductor crimp section and the conductor exposed section are closed by the waterproof sheet.

9. The connection structure of a crimp terminal with respect to a wire according to claim 8 ,
in which the confirmation window is provided in a position corresponding to the rear end of the conductor exposed section in the wire connection section.
