Connector for fluid piping and connector assembly

A connector assembly, comprising:

• a mating connector with a plurality of mating fluid pipes;
• and
• a connector having a housing main body with opposite front and rear ends, a receptacle open at the front end of the housing main body and being connectable to the mating connector, a sub-connector accommodating portion open at the rear end of the housing main body, a wall formed between the receptacle and the sub-connector accommodating portion and a plurality of pipe insertion holes formed through the wall;
• and
• at least one sub-connector detachably provided in the sub-connector accommodating portion of the housing main body, the sub-connector having a coupling plate with opposite first and second surfaces, the coupling plate being disposed in the sub-connector accommodating portion, a plurality of joint pipes unitary with the coupling plate of the sub-connector, each of the joint pipes having a first end projecting from the first surface of the coupling plate, passing through one of the pipe insertion holes in the wall of the housing main body into the receptacle and connected to one of the mating fluid pipes when the housing main body is connected to the mating connector, each of the joint pipes further having a second end projecting from the second surface of the coupling plate and connectable to one of a plurality of fluid tubes, and an engaging mechanism for holding the sub-connector engaged with the housing main body.

A hybrid connector for fluid and electrical connection, comprising:

• a housing main body having opposite front and rear ends, a receptacle open at the front end of the housing main body, an electrical connector housing integral with the housing main body and having cavities extending therethrough from the receptacle to the rear end of the housing main body, a sub-connector accommodating portion open at the rear end of the housing main body and having a wall forward of the rear end of the housing main body, pipe insertion holes formed through the wall of the sub-connector accommodating portion and into the receptacle;
• terminal fittings mounted respectively in the cavities;
• a sub-connector having a coupling plate detachably mounted in the sub-connector accommodating portion, the coupling plate having opposite front and rear surfaces, a plurality of joint pipes unitary with the coupling plate, each of the joint pipes having a pipe connecting portion projecting from the front surface of the coupling plate, through the pipe insertion holes in the back wall of the sub-connector accommodating portion and into the receptacle, each of the joint pipes further having a tube connecting portion projecting rearward from the rear surface of the coupling plate for connection with a fluid tube;
• and
• an engaging mechanism for holding the sub-connector engaged with the housing main body.
