Abstract

The CPA-attached connector 1 a includes a connector body 11 and a CPA member 12 . The connector body 11 includes a temporary latch portion 112 for the CPA member 12 , a full latch portion 113 which, before the mating with a mating connector, restricts full latch of the CPA member, and which, during the mating, cancels restriction of the full latch by the mating connector, and a hood portion 114 configured to cover, in a manner of a canopy, a portion of the CPA member 12 in the full latch state. The CPA member 12 includes a CPA body 121 and a finger rest portion 122 provided on the CPA body 121 , a portion of the finger rest portion 122 being exposed from the hood portion 114 even in the full latch state, an inclined surface 122 a being formed in the exposed portion to incline toward a central axis of the connector body 11 in accordance with a distance from the hood portion 114.

First claim

What is claimed is:

1 . A CPA-attached connector comprising:
a connector body including a peripheral wall in a tubular shape and configured to mate with a mating connector; and a CPA member attached to the connector body in a temporary latch state, and configured to, during mating between the connector body and the mating connector, assure the mating by making a full latch and prohibit mating cancellation, and configured to, before the mating cancellation, return to the temporary latch state to permit the mating cancellation, wherein the connector body includes:
a temporary latch portion which is provided on the peripheral wall and to which the CPA member is attached in the temporary latch state;
a full latch portion provided on the peripheral wall, the full latch portion being a portion to which, during the mating, the CPA member makes the full latch, and which, before the mating, restricts the full latch of the CPA member, and which, during the mating, cancels restriction of the full latch by the mating connector; and
a hood portion provided on the peripheral wall to cover, in a manner of a canopy, a portion of the CPA member in a full latch state, and
wherein the CPA member includes:
a CPA body configured to make the temporary latch to the temporary latch portion and make the full latch to the full latch portion; and
a finger rest portion which is a portion provided on the CPA body so as to be exposed from the hood portion in the temporary latch state and serving as a finger rest during transition to the full latch state, a portion of the finger rest portion being exposed from the hood portion even in the full latch state, an inclined surface being formed in the exposed portion to incline toward a central axis of the connector body in accordance with a distance from the hood portion.

2 . The CPA-attached connector according to claim 1 , wherein in the full latch state, the inclined surface of the finger rest portion starts to incline, toward the central axis, from a top portion located immediately below an edge of the hood portion on a side where the finger rest portion is exposed or located on an inner side of the hood portion that is inner than the edge of the hood portion.

3 . The CPA-attached connector according to claim 1 , wherein a notch recess that is notched in a shape recessed toward the hood portion is formed in an edge, on a side opposite to the hood portion, of the finger rest portion.

4 . The CPA-attached connector according to claim 1 , wherein the CPA body is provided with an arm portion extending in a cantilever shape in a mating direction for mating between the connector body and the mating connector, the arm portion being configured such that, before the mating, a lever-tip end portion of the arm portion comes into contact with the full latch portion to restrict the full latch, and during the mating, the lever-tip end portion is pushed up by the mating connector in such a manner as to allow the lever-tip end portion to pass over the full latch portion, so that restriction is cancelled, and the lever-tip end portion passes over and fully latches to the full latch portion.

5 . The CPA-attached connector according to claim 1 , wherein
during the mating, the full latch portion of the connector body passes over and latches to a protruding portion provided on an outer wall of the mating connector, and during the mating cancellation, the full latch portion passes over the protruding portion to be detached from the protruding portion, and the CPA body is provided with a cancellation prohibiting unit for prohibiting the mating cancellation by holding the full latch portion in a direction to prohibit passing over the protruding portion in the full latch state.

6 . The CPA-attached connector according to claim 1 , wherein the CPA member is returned to the temporary latch state when the CPA body is pulled in a cancellation direction opposite to a mating direction, and
a jig latching-recessed portion that is notched in a recessed shape to allow a jig for pulling the CPA member in the cancellation direction to latch to the CPA member is formed on an edge of the hood portion of the connector body on a side where the finger rest portion is exposed.

7 . A wire harness comprising:
the CPA-attached connector according to claim 1 ; and an electric wire extending from the connector body.

8 . A wire harness comprising:
the CPA-attached connector according to claim 2 ; and an electric wire extending from the connector body.

9 . A wire harness comprising:
the CPA-attached connector according to claim 3 ; and an electric wire extending from the connector body.

10 . A wire harness comprising:
the CPA-attached connector according to claim 4 ; and an electric wire extending from the connector body.

11 . A wire harness comprising:
the CPA-attached connector according to claim 5 ; and an electric wire extending from the connector body.

12 . A wire harness comprising:
the CPA-attached connector according to claim 6 ; and an electric wire extending from the connector body.
