A connector connectable to a pipe having an annular protrusion on an end portion outer circumference thereof includes a connector main body having, at an end thereof, a pipe insertion hole into which the pipe is inserted; a checker to be pushed in from a temporary stopping position with respect to the connector main body to a completely inserted position with respect to the connector main body; and a retainer disposed inside the connector main body, which is configured to restrict a movement of the checker from the temporary stopping position to the completely inserted position, before the pipe is inserted into the connector main body. The retainer has a retainer lock part in a lower end portion of the retainer. A retainer-locker, which locks the retainer lock part, is provided in a bottom portion on a pipe insertion hole side of the connector main body.

This application is a National Stage application of International Patent Application No. PCT/JP2016/077095, filed on Sep. 14, 2016, which claims priority to Japanese Patent Application No. JP 2015-197135 A, filed on Oct. 2, 2015. Both applications are hereby incorporated in their entirety.
The present invention relates to a connector used in connecting conduits such as fuel conduits, the connector having a check function that allows checking from outside if pipe connection is completely done.
As a connector having the above-described check function, there is a connector described in PTL 1 for example. The connector described in PTL 1 is structured so that a retainer, which is stretched out by a spool portion (annular protrusion) of a pipe, is slid towards a pipe insertion hole, in a direction opposite to the pipe-insertion direction, with an elastic restoring force of the retainer restoring its original shape, and with the slide of the retainer, it is possible to push in a checker from a temporary stopping position to a completely inserted position of the connector main body.
FIG. 1 A perspective view of a connector related to one embodiment of the present invention.
FIG. 2 A perspective view of the connector viewed from a direction different from FIG. 1.
FIG. 3 A single article drawing of a connector main body shown in FIG. 1 and FIG. 2.
The following describes an embodiment of the present invention with reference to attached drawings.
(Structure of Connector)
As shown in FIG. 1, a connector 100 which is one embodiment of the present invention is structured by a connector main body 1, a checker 2, and a retainer 3. This connector 100 is a conduit joint used for connecting conduits such as fuel conduits and the like.
