DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a connector for a hydraulic pressure hose. The connector comprises a body, provided with a first sleeve member to be fitted inside the end of a hydraulic pressure hose, and a connecting member which preferably includes a fixing means for a working tool and a fastening means, such as a threaded portion, for fastening the connector to a hydraulic system, as well as a second sleeve member to be fitted outside the end of a hydraulic pressure, hose face to face with the first sleeve member, the first and second sleeve members being adapted, upon mounting the connector on a hydraulic pressure hose, to squeeze toeards each other and to clamp the end of a hydraulic pressure hose therebetween.
BACKGROUND OF THE INVENTION
This type of connectors are prior known and particularly used in hydraulics. The modern hydraulic systems not only include more and more actuators but also a lot of controls. Electrical control, in terms of valves, pumps and hydraulic motors, is highly complicated and susceptible to trouble in modern systems.
SUMMARY OF THE INVENTION
An object of this invention is to provide such a connector for a hydraulic pressure hose, which is to a substantial degree capable of eliminating the present drawbacks and, thus, of improving the prior art. In order to achieve this object, a connector of the invention is primarily characterized in that at least a part of at least one of the sleeve members of the connector is electrically insulated from the body.
The above solution provides a simple-design hydraulic pressure hose connector, at the same time allowing possibilities for electric connection when applied to a hydraulic pressure hose which is fitted with one or more conductors with which one or more sleeve sections included in the sleeve member are in electrical contact when the connector is mounted on the end of a hydraulic pressure hose. Thus, the hydraulic pressure hose can be employed, on the one hand, as a hydraulic medium carrier hose and, on the other hand, for example, for the control of actuators in the transmission of electric messages.
The invention relates also to a hydraulic pressure hose for use in association with the connector.
The invention will now be described in more detail in the following specification with reference made to an exemplary embodiment shown in the accompanying drawings. In the drawings.
BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 shows a perspective view of a connector of the present invention mounted on a hydraulic pressure hose,
FIG. 2 shows a connector in a longitudinal section prior to mounting, and
FIG. 3 shows a connector mounted on the end of a hydraulic pressure hose also in a longitudinal section, and
FIG. 4 shows a second embodiment of the connector according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Rererring particularly to FIG. 1, a connector 1 of the invention is mounted on a hydraulic pressure hose 2. The outer surface of connector 1 is fitted with an electric coupling means 3 having an electric wire 4 extending therefrom. The electric coupling means 3 is a shaped piece assembled with a screw 5 to form a ring shape. Screw 5 extends between brackets 6 in the electric coupling piece.
FIG. 2, in particular, illustrates the main components of the connector of the present invention. Connector 1 has a body 7 which includes as its main components a first sleeve member 8 and a connecting member 11. The first sleeve member 8 is fitted inside a hydraulic pressure hose when installing the connector on a hydraulic pressure hose. The body 7 further includes a fastening means 10 for connection to a second sleeve member 9, said fastening means extending from the end of a hydraulic pressure hose as an integral part of sleeve member 8. The fastening means 10 is followed by connecting member 11 for the body 7, the connecting member including a fixing or gripping means 12 for a tool, for example, a nut member intended for an adjustable wrench, as well as a fastening means as an ext
