Definitions

  • the invention relates to a device for conveying fuel according to the preamble of the main claim.
  • a device for conveying fuel with components, in particular a delivery unit, a filter housing with a filter, a pressure regulator or a level sensor, and with laid in the device electrical lines which are fastened by means of so-called cable ties to the components.
  • the electrical lines connect, for example, the delivery unit and the level sensor with an electrical voltage source.
  • the disadvantage is that the fixation of the electrical lines by means of cable ties is complicated and expensive. In addition, the fixation is not always done in the same position.
  • the inventive device for conveying fuel with the characterizing features of the main claim has the advantage that the assembly of the electrical lines is simplified.
  • the fastening means is formed integrally on the component and has a closable opening through which the electrical lines can be inserted into the fastening means.
  • the fastening means has a closing portion which closes the opening and which is constructed in the manner of a lock, gate-shaped, leg-shaped, arm-shaped or wing-shaped, since in this way a very simple clipping of the electrical lines into the fastening means is made possible.
  • the closing portion is elastically resilient, since the fastener automatically closes in this way after the insertion of electrical lines.
  • the fastening means has two cantilever arms, one of which is the elastic closing portion and the other is a rigidly executed portion.
  • the rigid portion is designed so that there is corresponding space for the male electrical lines available.
  • the rigid section is robust and provided with a fillet to the base of the component to accommodate cable forces.
  • the fixing of the electrical lines always takes place reliably at the same location and the electrical lines receive a defined position in the device.
  • the fastener itself is already formed on the component and does not need to be additionally mounted.
  • the closing portion is elastically resiliently pressed against the end of the rigidly executed portion, so that once clipped electrical lines can not solve automatically from the fastener.
  • the two arms together with a wall portion of the component enclose a space in which the electrical lines are provided, wherein the wall portion of the component is formed angled according to an advantageous embodiment.
  • the elastic closing portion is correspondingly long and thus bendable, whereby low Einclips body are achieved during assembly of the electrical lines.
  • the fastening means is formed on a cover of the filter housing.
  • Fig.1 shows a simplified illustrated device for conveying Kraftstoff.mit a fastening means according to the invention for the electrical lines.
  • the device according to the invention is arranged, for example, in a storage container 1 and has, for example, a delivery unit 2, which draws in fuel and delivers it via a pressure line 3 to an internal combustion engine 4.
  • the delivery unit 2 is arranged for example in a storage container 5 and sucks fuel from this.
  • the storage tank 5 holds a sufficiently large volume of fuel around the delivery unit 2, so that it can aspirate liquid at any time.
  • a suction jet pump 6 is provided, which is operated via a branching off from the pressure line 3 3 Trebtechnisch.
  • a filter housing 10 is provided with a fine filter disposed therein, which frees the fuel of the pressure line 3 of dirt particles.
  • the device for example, a pressure regulator 11, which adjusts the pressure in the pressure line 3 to a predetermined value. If the pressure in the pressure line 3 exceeds the predetermined value, it opens and allows fuel to flow from the pressure line 3 back into the storage container 5.
  • the device has, for example, a tank level sensor 12, by means of which the level in the reservoir 1 can be determined.
  • the storage container 1 has a tank opening, not shown, through which the device according to the invention is inserted into the storage container 1.
  • This tank opening is closed by means of a tank flange 15, which is mechanically connected to the storage container 5, for example by means of connecting rods, not shown.
  • electrical lines 16 are provided which electrically connect, for example, the delivery unit 2 or the tank level sensor 12 with an external voltage source 17.
  • other electrical lines 16 may also be provided in the device, which connect certain components or components of the device, such as the pressure line 3, the filter housing 10 or the pressure regulator 11, with an electrical ground.
  • At least one fastening means 18 is provided, which fixes the electrical lines 16 at at least one predetermined point of the device.
  • the fastening means 18 is integrally formed on any component of the device, such as a cover 10.1 of the filter housing 10.
  • the filter housing 10 and the fastening means 18 are thus made of a single piece, for example by injection molding.
  • the fastening means 18 according to the invention has a closable opening 19, through which the electrical leads 16 can be inserted into the fastening means 18. It has an opening 19 closing closing portion 20 which is formed, for example, elastically resilient and therefore closes the opening 19 automatically.
  • Fig.2 shows a partial view of the fastener according to the invention after Fig.1 ,
  • the closing portion 20 is, for example, door-shaped, leg-shaped, arm-shaped or wing-shaped. In this way, the electrical leads 16 are particularly easy to clip.
  • the fastening means 18 has two cantilevered arms 20,21, one of which is the elastic closing portion 20 and the other is a rigidly executed portion 21.
  • the two arms 20,21 are integrally connected to the filter housing 10, so injection-molded in a common manufacturing step. At the transition to the filter housing 10, both arms 20,21 have radii.
  • the closing portion 20 elastically resiliently acts against the end of the rigidly executed portion 21 and closes the fastening means 18 such that no electrical line 16 can inadvertently come off the attachment or fixation.
  • the two arms 20,21 enclose together with a wall portion 22 of the relevant component, for example, the filter housing 10, a space 24 in which the electrical lines 16 are provided.
  • the wall portion 22 of the filter housing 10 is angled.
  • the rigidly formed portion 21 is, for example, partially ring-shaped, hook-shaped or bay-shaped and has on its side facing away from the space 24 a stiffening rib 25 which extends from the outside to a wall of the relevant component, such as the filter housing 10, and a high bending stiffness of achieved rigidly formed section 21.
  • the stiffening rib 25 has a smaller wall thickness than the rigidly executed section 21.
