Embodiment Construction

[0009] The term "connector" should be understood in the broadest sense and actually refers to a substantially cylindrical shaped part which is generally used to connect to a substantially tubular shaped part (tube , flange, etc.), or connected to an opening provided on the fuel tank, the part or the geometry of the opening allows the connector to be secured by crimping. Preferably, the connector is fixed to the tube. The invention works well when the connector is a filler connector and is secured to the filler tube of the fuel tank.

[0010] "Crimping" is understood to mean an operation in which the tongues are deformed (permanently or temporarily), these tongues are fixed on a tube or opening (which has a special shape for receiving these tongues) for mechanical secure the connector. Note that the crimp can be internal or external, ie the connector can either be inserted into an opening or tube, or slide over the top.

[0011] "Tongue" is understood to mean any protrusion ...

Abstract

Plastic adapter for fuel tank, the said adapter comprises crimping lugs (10) for fixing it to a pipe or an opening in the tank.

Description

Background technique [0001] Fuel tanks for motor vehicles are increasingly relying on plastics, especially for reasons of low weight (compared to equivalent metal parts) and better possibilities for molding complex shapes. Traditionally, plastic fuel tanks are made by extrusion / blow molding. This then creates a housing through which openings are provided to accommodate the various functions of the fuel system, including the fueling system. The latter (dosing system) usually consists of: [0002] - Filling caps to close the feeding system; [0003] - filling head and nozzle deflector, which usually constitute a device known as a filling connector; [0004] -Feeding tube. [0005] Connectors (feed and other connectors), like the case itself, are usually made of metal or plastic. Metal connectors are generally connected to plastic pipes or metal pipes by crimping, or are welded to metal pipes. In the case of plastic connectors, their parts are still generally connected to p...
