Abstract
A connector comprises a casing 20 with a pipe fitting bore 25 to which a pipe P is fitted; a pipe fixing component 30 which slides against the casing and fixed the pipe P when the pipe is fitted to the pipe fitting bore 25; and a seal component 40 that is mounted facing the pipe duct 26 to seal the pipe P. The pipe fixing component 30 is elastically deformed, when the pipe P is fitted, from the temporary stop position at which it is temporarily stopped in the pipe fitting bore 25, and moves to the connecting position where the pipe is fixed, it being possible to externally view whether the pipe fixing component 30 is in the connecting position. The connector requires no checker or the like to check the connection with the pipe P, thus preventing poor seals.
Claims16
A connector for connecting a pipe to another flow passage by engagement with a pipe engagement component formed on an outer circumference of the pipe, the connector comprising:
- casing having (i) a pipe duct configured to be connected to the pipe, (ii) a pipe fitting bore connected to the pipe duct and (iii) a viewing window;
- a pipe fixing component, slidably supported by the pipe fitting bore, for fixing the pipe to the casing, the pipe fixing component being constructed and arranged to have a stopper engagement tab including a temporary stop position for no fixing of the pipe and a connecting position for fixing of the pipe;
- and
- a seal component mounted facing the pipe duct for sealing the pipe,
- wherein the pipe fixing component is configured to be elastically deformable when sliding in the pipe fitting bore from the temporary stop position to the connecting position, and the connector is configured to enable the stopper engagement tab to open the viewing window and the pipe to be observable through the viewing window in the temporary stop position, and to close the viewing window and the pipe to be unobservable through the viewing window in the connecting position.
A connector for connecting a pipe to another flow passage by engagement with a pipe engagement component formed on an outer circumference of the pipe, the connector comprising:

- a pipe fixing component, slidably supported by the pipe fitting bore, for fixing the pipe to the casing, the pipe fixing component being constructed and arranged to have a temporary stop position for no fixing of the pipe and a connecting position for fixing of the pipe;
- and
- a seal component mounted facing the pipe duct for sealing the pipe,
- wherein the pipe fixing component is configured to be elastically deformable when sliding in the pipe fitting bore from the temporary stop position to the connecting position, and the connector is configured to enable the pipe fixing component to be observable in the connecting position and
- wherein the connector is configured such that the pipe does not reach the seal component when the pipe is inserted into the pipe fitting bore after the fixing component is put in the connecting position without a pipe.
