• the present invention relates to a device for securing electrical cables on a support.
• the invention also relates more specifically to a device for joining one or more electrical cables to a support present in a motor vehicle.
• the internal combustion engine In a motor vehicle, the internal combustion engine is fixed to the frame and the body by buffer supports or silentbloc, so as to respond to mechanical stresses, vibration type, related to its operation.
• the engine is thus mobile inside its engine compartment.
• the buffers allow the motor to have pendulum movements during operation.
• a series of electrical cables is used to provide power, power distribution and data transmission to and from the engine components.
• These cables may have a part, for example a first end, mechanically in connection with the movable motor and another part, for example a second end, mechanically in connection with the fixed body. It is necessary to have a very robust and precise fixation in a specific area used for the movement of the cables.
• a securing device makes it possible to group and hold together a single or several electrical cables, for example stranded.
• the securing device makes it possible, if necessary, to keep the electric cable or cables near and / or at a constant distance from a support.
• the groupings of cables between them are made, either according to a common starting point of connection, or according to of a common arrival point of connection, either according to the distance between their point of departure and their point of arrival.
• the cables are not likely to come into contact with moving parts of the motor which are not protected by a fairing.
• the bundled cables are less sensitive to vibrations generated by the internal combustion engine. Their risks of disconnection in the electrical connectors become extremely reduced.
• the cables are stored and run along the body or chassis. Thus, in case of breakdown of the vehicle, the cables do not interfere with the field of vision and the handling during the intervention of a repairer.
