Definitions

  • the present invention relates to a securing device suitable for mechanically securing at least one connector plug to a housing, according to the preamble of claim 1.
  • Control devices in particular safety control devices, for controlling a machine or technical system that have a modular structure are known from the prior art.
  • these modular control devices for example, different control modules in different performance classes, digital or analog, safe or non-safe input and output modules and network modules can be individually combined with one another in order to provide the control device with the desired control functions.
  • These modular control devices often have a so-called head module, which has connection interfaces for connecting one or more connector plugs. These can in particular be so-called M12 connector plugs.
  • head module which has connection interfaces for connecting one or more connector plugs.
  • M12 connector plugs can in particular be so-called M12 connector plugs.
  • a generic safety device is from the US$4,917,627 known.
  • the present invention has for its object to provide a security device for mechanically securing at least one connector plug to a housing, which in a simple manner creates secure vibration and/or manipulation protection of the electrical plug connection.
  • the securing device is characterized according to the invention in that the receiving section has a collar portion which is partially annular, and that the contact surface has tolerance-compensating shapes and/or structures which are elastically deformable.
  • the security device With the aid of the security device according to the invention, effective protection against vibration and/or manipulation of the electrical plug connection, which includes the connector plug, is achieved in a simple manner by securing the connector plug in a suitable manner to the base body of the security device, which is preferably made in one piece from plastic, by means of at least one of the band-shaped, tightenable security means. Furthermore, mechanical stress on soldering points within the housing, which are exposed to the force of the connector plug during vibrations, can also be effectively reduced. Depending on their positioning, the security means can also form protection against manipulation for the connector plug by preventing the connector plug from being unscrewed or pulled off.
  • the security means can also prevent the base body of the security device from being removed from the housing, so that effective protection against manipulation and loss for the security device itself is also provided.
  • the band-shaped, tightenable security means can be designed as cable ties, for example. Other designs of the band-shaped security means, which can optionally also be sealed after assembly, are also possible in principle.
  • the safety device is particularly suitable for the mechanical securing of one or more connector plugs that are connected to a head module of a modular control device, in particular a modular safety control device.
  • the safety device can be a pre-assembled component or also a retrofit part.
  • the security device according to the invention is particularly suitable for securing M12 connector plugs, which can be straight or angled.
  • the security device can preferably be designed in such a way that the insertion and/or locking of a connector plug can be prevented by sealing or tightening at least one of the band-shaped securing means when no connector plug is to be connected. This also creates protection against manipulation.
  • the receiving section is partially cylindrical and has a contact surface for the connector plug.
  • the connector plug can be secured directly to the receiving section by means of one of the band-shaped, tightenable securing means.
  • the invention further provides that the receiving section has a collar section at a free end which is partially ring-shaped and preferably includes an undercut. This collar section enables the at least one band-shaped securing means to be securely attached to the receiving section.
  • the contact surface has tolerance-compensating shapes and/or structures that are designed to be elastically deformable. In addition to improved vibration damping, this also makes it possible designed to compensate for any differences in diameter between different connector plugs.
  • the base body prefferably has two retaining rails that extend parallel to one another and are spaced apart from one another in such a way that they are suitable for being pushed laterally onto the housing during assembly.
  • the retaining rails can preferably be designed in such a way that projections formed on a front side of the housing and extending outwards in the opposite direction can engage in the retaining rails, preferably in a form-fitting manner, during assembly of the safety device.
  • the base body has an elastically pivotable latch that is designed such that it is suitable for engaging in a latching recess on a front side of the housing in a desired assembly position of the safety device.
  • the base body has a stop surface on its outer side facing away from the housing during assembly, which is suitable for interacting with a band-shaped securing means received in a receiving eyelet in the side wall of the housing and tightened therein.
  • the base body has at least one retaining web which, after assembly of the base body, extends at a distance from the front of the housing and to which at least one of the band-shaped, tightenable securing means can be secured, wherein the retaining web preferably has an anti-slip, in particular grooved, structure on its underside.
  • One of the band-shaped securing means which also extends in sections around the connector plug after assembly, can be attached to this retaining web.
  • the anti-slip, in particular grooved, structure on the underside of the retaining web can effectively prevent the band-shaped securing means tightened to it from slipping.
  • the base body can have a side wall with at least one receptacle, the receptacle being designed to receive a connecting cable of the connector plug and to secure it therein by means of one of the band-shaped, tightenable securing means.
  • This measure makes it possible, for example, to secure a connecting cable that is connected to an angled connector plug to the base body.
  • the receptacle can preferably be V-shaped or U-shaped and comprise two legs, each of which has an opening. The connecting cable of an angled electrical connector plug can be received in this V-shaped or U-shaped receptacle.
  • One of the band-shaped securing means in particular a cable tie, is then passed through the openings of the two legs of the V-shaped or U-shaped receptacle and passed around the connecting cable and then tightened.
