Description

A connector unit (CONNECTION UNIT)

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connector for connecting pipes of a hydraulic system, and more particularly to a connector unit in which a pipe is easily detachable from a hydraulic device.

Generally, the mechanism for transmitting the power of the vehicle includes a clutch portion and a clutch control portion. Here, the clutch operating mechanism of the clutch control section is divided into a mechanical type and a hydraulic type. In general, a hydraulic cylinder type is often applied to reduce a load on a driver's leg when the driver depresses the clutch pedal. The system can operate in the following order: clutch pedal → clutch master cylinder → hydraulic hose → clutch release cylinder → release lever → release fork → release bearing → clutch. At this time, the pressing force of the pedal can reduce the load applied to the pedal by the hydraulic pressure ratio between the clutch master cylinder and the clutch release cylinder.

On the other hand, automotive concentric slave cylinders are applied to hydraulic clutches and are configured in a modular form incorporating the functions of clutch release cylinders and release levers, release bearings, release forks, pivots and input shafts in conventional clutch control systems , And is designed to have reliability at high temperatures as it is mounted inside the transmission housing.

According to a conventional connector (Patent No. 10-1092708), when a pipe is fitted to a connector, a protrusion of the pipe is seated in a groove formed in the inner surface of the through hole to prevent the pipe from coming off the connector. Then, a sealer was inserted and connected to one end of the connector.

Here, in order for the protrusion of the pipe to be seated in the groove, the protrusion of the pipe must be formed of an elastic body, and the protrusion must be restored by inserting the inner surface of the pipe.

If the projection is not formed of an elastic body, when the pipe is fitted into the connector, the projection may not be crushed or protruded, and the pipe can not be inserted into the connector.

The sealer also has to be formed as an elastic body so that it can be fitted and fixed to the connector.

For this reason, when the pipe is pulled or the pipe is caught by an obstacle, the protrusion is formed as an elastic body, so that the problem that the pipe is easily released from the connector occurs.

Further, even if the pipe is fitted to the sealer, since the sealer is also formed of an elastic body, there arises a problem that the pipe is pulled out from the sealer if a pulling force is applied to the pipe. That is, although the sealer can seal the periphery of the pipe, it is difficult to fix the pipe. Moreover, since the sealer is inserted into the connector, the sealer and the connector are separated from each other if an external shock is applied.

Further, a great deal of force is required to separate the pipe and the connector, which makes it difficult to separate the pipe from the connector.

Korean Patent No. 10-1092708 (December 05, 2011)
