Definitions

  • the present invention relates to a fan having a housing, with a cover element being arranged on the underside of the housing.
  • the present invention relates to a cover element for a fan.
  • Fans are used in many different technical applications for cooling electronic devices and components or for ventilation. Fans are used in particular in comfort applications, for example in the automotive sector. Particular attention is paid to the noise emissions of the fans, particularly in comfort applications.
  • ESD protection electrostatic discharge
  • the electrical connection of the electrical line on the printed circuit board is inside the housing, it is no longer accessible early in the production process. Therefore, the length of the electrical line is already fixed early in the production process by attaching the electrical line and can only be changed afterwards with great effort.
  • Another problem is that the electrical wiring, which was installed at an early stage, has to be routed through the entire further production process, which makes the manufacture of the fan complex.
  • the electrical cable must be provided with a strain relief.
  • a fan has a housing, with an electric motor and a fan wheel that can be driven or driven by the electric motor being arranged in the housing, with the housing having an opening for an electrical connection on the underside of the housing, with the housing being connected to has a bracket on one peripheral side, so that a bushing is formed between the bracket and the peripheral side, an electrical line being arranged at least partially on the underside of the housing and being guided through the bushing, it also being provided that a cover element is arranged on the underside of the housing, wherein the cover element has a first section and a second section, the first section and the second section being arranged at an angle to one another, and the cover element being arranged on the underside of the housing in such a way that the first section is at least is partially arranged in the bushing and clamps the electrical line forming a strain relief in the bushing, and that the second section covers the opening.
  • the opening can also be arranged in a housing top side of the housing.
  • the opening is preferably located between the axis of rotation of the fan wheel and the peripheral side of the housing, viewed in a radial direction of the housing.
  • the electrical line is routed through the passage between the bracket and the peripheral side and runs from there to the opening in the underside of the housing.
  • the peripheral side and the underside of the housing are at an angle of preferably approximately 90° to one another, so that the electrical line runs over the edge at the transition from the peripheral side to the underside of the housing.
  • the bracket arranged on the peripheral side of the housing can be attached to the peripheral side on one side or only with one end of the bracket, so that the passage is open on one side. Furthermore, the bracket can also be fastened on both sides or with both bracket ends on the peripheral side, so that the passage is formed like an eyelet.
  • the cover element provided according to the invention comprising the first section and the second section, is advantageously designed both to provide strain relief for the electrical line and to ensure ESD protection and noise insulation of the fan.
  • the strain relief is achieved in that the first section is at least partially arranged in the bushing and clamps the electrical line in the bushing.
  • the second section of the covering element covers the opening, as a result of which the inside of the housing and/or an electrical connection is covered for ESD protection. Furthermore, the noise emissions of the fan are reduced by covering the opening.
  • the cover element on the fan according to the invention offers the particular advantage of combined ESD protection and strain relief for the electrical line in one component.
  • the cover element is preferably essentially L-shaped.
  • the cover element Because of the L-shape of the cover element, it encompasses the edge at the transition from the peripheral side to the underside of the housing.
  • the first section runs approximately parallel to the peripheral side.
  • the second section runs approximately parallel to the underside of the housing.
  • the formation of a channel covered with the second section of the cover element protects the electrical line arranged therein from the outside, so that the risk of the electrical line being damaged in the production process or during installation in an application is reduced.
  • the housing has a depression running in a radial direction in the underside of the housing, with the second section covering the radial depression to form the channel.
  • the channel is formed between the cover member and the recess.
  • the indentation running in the radial direction preferably runs, starting from the opening arranged in the underside of the housing, in the direction of the circumferential side towards the strap of the strain relief.
  • the electrical line which is routed through the passage between the bracket and the peripheral side, runs over the edge at the transition between the peripheral side and the underside of the housing and disappears in the channel formed by the recess and the cover element.
  • the electrical line runs further in the channel in the direction of the opening, so that an electrical connection for operating the fan can be provided.
  • the deepening can be done by a corresponding configuration of the housing wall of the housing bottom are provided. For this purpose it can be provided that the housing wall of the housing underside is arched in the direction of the housing interior into the housing.
  • the electrical line arranged therein is arranged approximately in the plane of extension of the underside of the housing.
  • the overall height of the fan can be reduced as a result.
  • the printed circuit board is further preferably arranged concentrically around the axis of rotation of the fan wheel on the inside of the housing.
  • the electric motor for driving the fan wheel and electronic components for controlling the fan can also be arranged on the printed circuit board.
  • the printed circuit board essentially covers the opening from the inside of the housing. This leads to a further reduction in noise emissions from the inside of the fan housing.
  • An electrical connection can preferably be provided, comprising a first, preferably female, part of a plug-in connection which is arranged on the circuit board and protrudes through the opening and is covered by the second section.
  • a plug-in connection is therefore preferably provided to provide the electrical connection.
  • a first part of the plug connection, preferably a female part, of the plug connection is arranged on the printed circuit board in such a way that it protrudes through the opening and is covered by the second section.
  • the first part of the connector is thus located between the printed circuit board and the second section of the cover element.
  • the opening is consequently from the inside of the housing preferably covered by the printed circuit board and from the outside by the second section.
  • the opening is largely filled by the first part of the plug connection projecting through the opening. All in all, these measures ensure a significant reduction in noise emissions from the inside of the housing.
  • the electrical connection comprises a second, preferably male, part of the plug-in connection which is arranged at the end on the electrical line and which is in operative connection with the first part.
  • the male part of the plug connection is particularly preferably arranged in the female part of the plug connection.
  • the design of the electrical connection as a plug-in connection comprising the first and the second part, the first part being arranged on the printed circuit board and protruding through the opening, overcomes the problem known in the prior art that the electrical line for the power supply is switched off early on attached to the printed circuit board inside the housing during the production process of the fan and must be carried through the rest of the production process.
  • the fan comprising the housing, fan wheel, electric motor and printed circuit board can be manufactured essentially completely before the electrical line has to be connected. Only in late production steps is the electrical line arranged on the fan by connecting the first part of the plug connection to the second part of the plug connection.
  • the cover element is then arranged on the underside of the housing in such a way that the second section covers the opening and the electrical line and preferably also the plug connection and that the first section of the cover element clamps the electrical line in the bushing to produce strain relief. Also needs the length of the electrical application-related only towards the end of the production process.
  • the first part of the plug connection in particular the female part of the plug connection, is preferably arranged or fastened on the printed circuit board as an SMD component (surface-mounted device) using an SMT method (surface-mounted technology).
  • An opening is thus formed between the longitudinal webs and the transverse web and an area of the second section facing the first section. Due to the bow-shaped configuration of the first section, material for the production of the covering element can be saved.
  • a latching element protruding from the plane of extent of the first section at an angle is arranged on the transverse web.
  • the latching element can grip behind the bracket when the first section has been fed sufficiently deep through the bushing, so that the locking element clicks into place behind the bracket.
  • the cover element is thus held captively on the housing of the fan.
  • the second section preferably has two longitudinal edge webs and a cover plate extending between the edge webs.
  • the cover element can be inserted into the indentation with the edge webs.
  • the cover plate of the cover element is then held at a distance from the underside of the housing by the edge webs, so that the channel for the electrical line is formed between the cover plate and the underside of the housing.
  • the cover plate fulfills the function of covering the opening in the underside of the housing or the plug-in connection from the outside.
  • the second section has a first section and a second section, with a step being formed on an underside of the cover plate between the first section and the second section.
  • the first partial section of the second section of the cover element is preferably arranged adjacent to the first section of the cover element, which is at an angle to the second section.
  • the second partial section of the second section of the cover element is arranged on the side of the second section facing away from the first section.
  • the step is arranged on the underside of the cover element between the partial sections.
  • the second partial section of the second section is preferably arranged above the opening in the underside of the housing.
  • the second part of the plug-in connection bears against the step of the second section, so that the second part of the plug-in connection is prevented from sliding out of the first part.
  • The, in particular male, second part of the plug connection is thus secured by means of a positive fit on the step in the cover element.
  • the first section has a curved or curved transition area on the underside in the area of the step.
  • the angle between the first section and the stepped shoulder is increased by a curved or bent or beveled transition area. This has the advantage that the electrical line, which runs in the duct below the first section to the second section, is less heavily stressed by compression and bending at the step.
  • the cover plate can also advantageously be made for the cover plate to have wing sections, at least in the second section, which protrude laterally beyond the edge webs on an upper side of the cover element.
  • the cover element and in particular the second section of the cover element with the edge webs is arranged in the recess of the housing underside of the fan, the wing section of the cover plate protrudes laterally beyond the edge webs and rests on the side of the recess on the housing underside of the fan. This contact of the wing section on the underside of the housing further minimizes noise.
  • an end piece protrudes in the direction of the underside of the cover element at an end of the cover plate facing away from the first section.
  • the closing piece preferably runs transversely to the ends of the edge webs of the second section facing away from the first section and fulfills two functions.
  • the end piece engages behind the plug connection, in particular the female part of the plug connection, on the side opposite the step, so that a relative positioning of the cover element with respect to the plug connection is simplified.
  • the end piece rests on the underside of the fan housing, which minimizes noise emissions.
  • edge webs each have a latching projection on an end facing away from the first section.
  • the latching projections on the edge webs engage behind the opening in the underside of the housing.
  • the ends of the edge webs facing away from the first section are at least partially arranged in the opening in the underside of the housing of the fan.
  • the latching projections engage behind a radially inner area of the opening, so that the cover element is held captively on the housing by the latching projections in cooperation with the latching element of the first section.
  • the cover element can preferably be connected or is connected to the housing with a clip connection.
  • the latching element engages behind the bracket.
