Further, a pin 8 and a groove 9 which can be engaged with each other at an angular position where the plug member 2 and the socket member 3 are fitted are formed in a portion where the coupler plug 4 and the coupler socket 5 are fitted to each other. A rotary joint 10 is provided that allows rotation within a certain angle range with respect to a hose (not shown). The rotary joint 10 includes a pin 11 protruding from one side and a stopper such as a fitting groove or the like, and is provided with a rotation preventing mechanism that limits a rotation range. It is sufficient if the operation range exceeds 180 degrees.

As a coupler for a hydraulic hose, a coupler generally known as a so-called one-touch detachable type is used. The illustrated example is a ball type (details omitted) and includes a sleeve-shaped lock member 12. In addition to the ball type, specifically, the lever type and the ring type are applicable,
The present invention is not limited to these, and all couplers for hydraulic hoses capable of connecting and disconnecting hydraulic paths by simple operations are applicable.

The schematic structure of the one-touch detachable hydraulic hose coupler is as follows.
In the ball type, a circumferential groove is formed on the outer periphery on the plug side, and a ball forming an engaging member engageable in the circumferential groove is provided so as to be able to protrude and retract in the radial direction from the inner surface on the socket side, and this engaging member is locked. A coupler configured to include a slidable lock sleeve as a possible restraining member. By sliding the lock sleeve to a lock position or an unlock position, a one-touch attachment / detachment operation between the plug side and the socket side is enabled.

In the lever type, a circling groove is formed on the outer periphery on the plug side, and an eccentric body serving as an engaging member engageable in the circulating groove is rotatably provided. It is a coupler that is configured by protruding an operation lever for it. By rotating the operation lever, one-touch attachment / detachment operation between the plug side and the socket side is enabled.

In the ring type, a sleeve that can be fitted to the plug side is provided so as to be able to rotate around the socket side, and a projection is inserted into one of the engagement surfaces of the two and the projection is inserted into the other side, and the sleeve is moved in the axial direction. This is a coupler having a bent groove formed to bend to restrain the coupler. The one-touch attachment / detachment operation between the plug side and the socket side is enabled by the rotation operation of the sleeve.

In the cable connector 1, the coupler member 4 is fitted into the coupler socket 5 and the lock member 12 is operated, whereby the internally provided plug member 2 and socket member 3 are connected and fixed.

In the cable connector 1 having the above-described structure, the coupler plug 4 and the coupler socket 5 form a coupler for a hydraulic hose and are fixed watertight by a one-touch mounting operation of the lock member 12, so that the cable connector 1 can be used in a muddy environment such as civil engineering work. Also, waterproofness and operability can be ensured. In addition, since the cable is covered by the hose, the cable can be prevented from being damaged even if it comes into contact with an obstacle, so that the durability of the cable can be ensured.

When the cable connector 1 is connected, pins 8 and grooves 9 are formed on the coupler plug 4 side and the coupler socket 5 side for the hydraulic hose that can engage with each other at a fixed angle position. By moving it, fitting can be performed only at a fixed angle position, and damage to pins and the like due to erroneous operation can be prevented.

At this time, since the rotation of the hose within a certain angle range is allowed by the rotary joint 10, the excessively twisting of the cable 6 can be avoided, and the angular position of the connector can be easily adjusted by a reasonable turning operation. Can be adjusted to
