DESCRIPTION

CONNECTION DEVICE FOR INCREASE UNE AS

TECHNICAL FIELD OF THE INVENTION

The present invention falls within the technical field of the connections of power lines that are used to supply, through power lines, electricity and work fluids, such as pneumatic fluids and hydraulic fluids from a supply source to parts and devices that require electricity or such work fluids for operation.

These connections are especially used between motor vehicles, especially trucks, and their trailers or semi-trailers, but also for example between tractor and railroad cars.

BACKGROUND OF THE INVENTION

At present, the electrical and pneumatic or hydraulic connection between the tractor unit of a heavy vehicle and its corresponding trailer is usually carried out through a plurality of power lines with its different electrical connector elements coupled at respective ends of the electric cables. , and in the case of feed lines for work fluids, such as pneumatic or hydraulic lines, fluid connection elements. It is of vital importance for the operation and circulation of the vehicle, these power lines must work perfectly, for feeding the safety systems necessary for the movement of the vehicle.

The power lines are usually made up of spiral hoses, which allows them to distend and contract when they have to withstand the maneuvers of the vehicle in different daily maneuvering situations. The location of the feeding lines is limited to a reduced space, for example the one between the tractor and the trailer, which causes an interaction between the same, as well as friction, hooks, blows, etc., and on numerous occasions it results in a breakage of one or more of said lines, produced by a maneuver of the vehicle or simply by the interaction produced between them of blows, strains or wear. Also in practice the wear of the hoses is uneven depending on whether they are electrical or pneumatic.

Being a solution that involves several elements, to safeguard the operation of the vehicle, this forces the driver of the vehicle to carry somewhere the same corresponding to each element to be able to replace the used replacement with a new one in the reserve kit In the event of a breakdown, given that if a breakage occurs and the replacement is not available, the vehicle is immobilized with the consequent economic, time, etc. damages.

In short, the current connection solution, as a minimum, requires drivers or users of heavy vehicles to pay attention to the care of these power lines, their connections, be provided at all times with the necessary stock on board the vehicle of the spare parts corresponding as well as its replacement once the item in question is repaired.

On the other hand, in the conventional systems each power line must be connected separately, which requires attention and time by the user when making the connections of the different lines between the connected connectors the power supply or pressure and the connectors connected to the electricity or pressure consuming elements. If this is coupled with the uneven wear of each hose we find a situation of unpredictable and constant failure and replacement of hoses, without the useful life of all of them can be properly planned or coordinated.

Another disadvantage of the connection devices of! State of the art is that when the fluid connection hoses are disconnected from the fixed connectors, the fluid and working pressure are lost, which in practice leads users to leave said hoses hanging from the fixed connection, which It increases not only your exposure to dirt and wear, but the risk and frequency of your theft. Document ES 1 180 650 refers to a power line connection device where the device comprises first electrical connector elements each connected to an electrical power source, first fluid connection elements connected to a working fluid source, a power supply line comprising a plurality of electrical cables with two second electrical connector elements coupled at respective first ends of the electrical cables, and each connected to one of the first electrical connector elements in a male-female connection. Said device comprises a working fluid feed line comprising at least one flexible conductive tube of a working fluid, with a second fluid connection element coupled to a first end of a flexible tube, designed to carry a working fluid. selected between pneumatic fluids and hydraulic fluids, and each connecting them to a first fluid connection element in a first quick connection.
