Definitions
- the invention relates to a coil carrier with a receptacle for a safety switch.
- safety switches such as guards
- guards With electrical coils, safety switches, such as guards, must be provided to protect against overcurrent and overtemperature. Up to now, these have generally been provided on the coil carrier of the coil in a complicated and complex manner. It is not reliable to hold it and the contacting of the contact elements of the safety switch with the coil to be wound onto the coil carrier is generally complex.
- the invention is therefore based on the object of providing a bobbin of the generic type which ensures reliable hold and reliable contacting of the safety switch and simple and convenient connection options.
- the above-mentioned object is achieved in the case of a coil carrier of the type mentioned at the beginning by an electrically conductive receiving part for the safety switch with a recess for frictionally receiving the safety switch.
- the safety switch is no longer connected as such to the coil carrier or inserted into it, but is held by a receiving or holding part, which at the same time ensures the electrical contact via the housing shell forming a contact of the switch.
- the design according to the invention allows the switch to be held securely and reliably on the coil carrier, in particular in a receptacle thereof.
- the receiving part is plate-shaped and a flange surrounding the recess is bent out on the plate level. This ensures a flat contact of the conductive housing on the flanges or tabs of the coil carrier. To increase the elasticity it can further be provided that the receiving part has a slot extending from the recess to an outer edge.
- a further development provides that the receiving part has lugs punched out of its plane in the edge region. In this way, in particular if the receiving part is guided in grooves in the receiving means of the coil carrier, the safety switch can be securely fixed and thus secured against slipping out or being pulled out.
- connection tab is designed as a flat plug or a connection tab with a tapered portion formed by an undercut.
- the inventive concept is further supported by the fact that the receptacle has longitudinal grooves in which the receptacle is seated, so that the winding coil can be contacted directly on the connecting wire of the switch during winding.
- the coil carrier 1 has a carrier core 2 and this delimiting, parallel to each other limiting plates 3, so that a coil winding can be applied to the carrier core 2 in the plates 3.
- a receptacle 4 for a safety switch 6 is formed on the side of one of the boundary plates 3.
- the safety switch 6 is a bimetal overcurrent switch, such as a temperature monitor.
- the receptacle 4 for the switch 6 is designed as a pocket.
- the pocket is essentially delimited by the boundary wall 3, a wall 7 running parallel to this and longitudinal side walls 8 perpendicular to these.
- the receptacle 4 has an insertion opening 9 for inserting the switch 6 and the insertion opening 9 opposite an opening 11 in the rear wall of the receptacle 4, through which a connecting wire 12 out of the receptacle 4 and through a slot 13 can be guided into the winding area 14 of the coil winding.
- a receiving part 17 for receiving and holding the switch 6 can be inserted into the receptacle 9 of the coil carrier 1.
- the receiving part 17 has a width corresponding to the width of the receptacle 9, taking into account the grooves 16, and a length substantially corresponding to the receptacle 9.
- the receptacle part 17 is surmounted by a tab 18, which is designed as a flat plug and can be plugged onto the corresponding sockets for contacting.
- the tab 18 protrudes from the opening 9 of the receptacle 4.
- the receiving part 17 has a circular opening 19.
- the opening 19 is delimited by an annular flange 21 which is bent out of the plane of the flat receiving part 17.
- the receiving part between the recess 19 and its end face 22 facing away from the connecting lug 18 has a slot 23 which supports the elasticity of the receiving part 17 in the region of the recess 19.
- lugs 26 are embossed out of the plane of the receiving part 17 and prevent the receiving part 17 from slipping out or being pulled out of the receptacle 4.
- connection plate 28 of a different type from the connection plate 18, which is designed as a flat plug is provided, which has undercuts 29, so that contact is made here, for example by moving around winding a piece of wire around the tapered part 31 of the connecting tab 28 can be made.
- the connecting tab 18 designed as a flat plug can also be provided. If necessary, one of the two connecting lugs 18, 28 can be cut off if it is not required.
- the design according to the invention provides a coil carrier 1 which is provided with a safety switch 6 and which offers simple and convenient connection options.
- a secure mounting and at the same time reliable contacting of the switch 6 is provided via the receiving part 17, which is held reliably and firmly in the receptacle 4 and forms a connection contact for connecting the electrical power supply, while the other contact of the switch 6 via a connecting wire is guided to the winding space of the coil within the coil carrier 1, so that the coil can be easily and conveniently connected to it there, while its other end forms the contact to the power supply.
