Abstract

A pair of connectors includes first and second connectors. The first connector includes a first assembling surface that contacts the second connector. The second connector includes a second assembling surface that contacts the first assembling surface. The first connector includes a first overhanging portion, which overhangs outward from the second assembling surface in an assembled state of the first and second connectors, and a first projecting portion, which projects from the first overhanging portion beyond a location of the first assembling surface toward the second connector side in the assembled state. The second connector includes a second overhanging portion, which overhangs outward from the first assembling surface in the assembled state, and a second projecting portion, which projects from the second overhanging portion beyond a location of the second assembling surface toward the first connector side in the assembled state.

First claim

What is claimed is:

1. A pair of connectors comprising:
a first connector that is configured to be coupled to a first flow passage forming member, which is configured to conduct a fluid; and
a second connector that is configured to be coupled to a second flow passage forming member, which is configured to conduct the fluid, while the second connector is assembled to the first connector, wherein:
the first connector includes a first assembling surface that contacts the second connector in an assembled state where the first connector and the second connector are assembled together;
a first flow passage through-hole and a first fixation through-hole are formed in the first assembling surface;
the second connector includes a second assembling surface that contacts the first assembling surface in the assembled state where the first connector and the second connector are assembled together;
a second flow passage through-hole is formed at a corresponding location of the second assembling surface, which is opposed to the first flow passage through-hole in the assembled state where the first connector and the second connector are assembled together, and a second fixation through-hole is formed at a corresponding location of the second assembling surface, which is opposed to the first fixation through-hole in the assembled state where the first connector and the second connector are assembled together;
in the assembled state where the first connector and the second connector are assembled together, a fixing member is inserted into the first fixation through-hole and the second fixation through-hole, and the fluid flows from one of the first flow passage forming member and the second flow passage forming member to the other one of the first flow passage forming member and the second flow passage forming member through the first flow passage through-hole and the second flow passage through-hole;
the first connector includes a first overhanging portion, which overhangs outward from the second assembling surface in the assembled state where the first connector and the second connector are assembled together, and a first projecting portion, which projects from the first overhanging portion beyond a location of the first assembling surface toward a second connector side where the second connector is placed in the assembled state where the first connector and the second connector are assembled together;
the second connector includes a second overhanging portion, which overhangs outward from the first assembling surface in the assembled state where the first connector and the second connector are assembled together, and a second projecting portion, which projects from the second overhanging portion beyond a location of the second assembling surface toward a first connector side where the first connector is placed in the assembled state where the first connector and the second connector are assembled together; and
the first overhanging portion and the second overhanging portion are both located on one side of the first fixation through-hole and the second fixation through-hole, which is opposite to the first flow passage through-hole and the second flow passage through-hole in a direction of a straight line that connects between an axis of the first fixation through-hole and the second fixation through-hole and an axis of the first flow passage through-hole and the second flow passage through-hole in the assembled state.

2. The pair of connectors according to claim 1 , wherein:
the pair of connectors is configured to be used in a refrigeration cycle apparatus for a vehicle; and
the fluid is a refrigerant.

3. A refrigeration cycle apparatus comprising:
the pair of connectors of claim 1 ;
the first flow passage forming member; and
the second flow passage forming member.

4. The refrigeration cycle apparatus according to claim 3 , comprising:
a heat radiator that includes the first flow passage forming member, through which a refrigerant is inputted into the heat radiator, wherein the heat radiator radiates heat from the refrigerant; and
the second flow passage forming member has a charge valve for charging the refrigerant.

5. The pair of connectors according to claim 1 , wherein the first overhanging portion and the second overhanging portion are arranged side by side in a direction that is perpendicular to the direction of the straight line.

6. The pair of connectors according to claim 1 , wherein the first overhanging portion and the second overhanging portion are bisected by the straight line.
