Definitions
- the invention relates to a housing for an electrical component, in particular for a coil for electromagnetically actuated valves, according to the preamble of patent claim 1.
- Coils which are provided in particular for electromagnetically actuated valves, can be provided, for example, with a plastic casing serving as a housing to protect them against the ingress of moisture and dust. It is conceivable to design the housing in a pot shape and to close it with a lid serving as a carrier for an electrically conductive plug pin.
- a guide and protective frame can be formed on the side of the carrier facing away from the coil housing. The guiding and protective frame also serves to guide and secure an electrical coupling.
- the carrier for the plug pin can be connected to the housing by means of a screw connection with the interposition of a sealing ring between the cup-shaped housing and the carrier.
- a one-piece design of the housing and the carrier provided with the guide and protective frame is problematic since the housing often consists of a heat-resistant thermoset, but the guide and protective frame must consist of an elastic material in order to prevent an electrical coupling from being inserted incorrectly into the guide - and protective frame or other mechanical loads to prevent breakage of the guide and protective frame.
- the invention is therefore based on the object of improving a housing for an electrical component of the type mentioned in such a way that a simplified structure of the housing and a secure seal of the electrical component is achieved with simple means.
- the invention offers the advantage, in particular, of obtaining a housing for an electrical component with simple means, which is protected from moisture and dirt by the design of the housing and the support for the plug pins as a one-piece structural unit, and by the design of the guide and protective frame to receive an unbreakable receptacle for an electrical coupling as an independent component that can be connected to the housing.
- the guide and protective frame can be exchanged in a simple manner without having to make any changes to the housing or to the carrier for the plug pins. Due to the interchangeability of the guide and protective frame, different electrical couplings can be connected in their dimensions to the electrical component provided with the housing according to the invention.
- the illustration shows a housing for a coil with an exchangeable guide and protective frame.
- a coil 2 is shown, which is coated with a plastic mass.
- the plastic mass is preferably a heat-resistant thermosetting plastic and forms the housing 1 of the coil 2.
- a core is arranged centrally in the injection mold, which core is used as a guide tube 3 in the housing after the injection molding around the coil for an anchor serving cylindrical opening.
- the injection mold is designed so that the housing 1 receives a projection which serves as a carrier 4 for two connector pins 8, 9.
- the connector pins 8, 9 and the connecting lines 14, 15 from the coil 2 to the connector pins 8, 9 are simultaneously injected into the carrier 4 during the encapsulation of the coil, so that the connector pins 8, 9 of the carrier 4 and the housing 1 are in one piece Unit forms.
- a recess 13 is provided running in the circumferential direction of the carrier 4. Another groove-like recess running in the circumferential direction of the carrier 4 serves to mount a sealing ring 10.
- a tubular guide and protective frame 5 is pushed onto the carrier 4.
- the guide and protective frame 5 has on its inner wall a circumferential projection 12 which extends onto the lateral surface (wall) of the carrier 4 and which engages in the recess 13 of the carrier 4 and forms a latching connection therewith.
- the guide and protective frame 5 is dimensioned in the direction of its longitudinal axis so that it projects so far beyond the connector pins 8, 9 anchored in the carrier that they are protected against mechanical influences.
- nose-like projections 6, 11 are provided which, when an electrical coupling is pushed onto the guide and protective frame, cooperates with corresponding recesses provided in the coupling housing in the manner of a snap connection.
- the nose-like projections can be dispensed with if the coupling is inserted into the interior 7 of the guide and protective frame 5.
- the sealing ring 10 prevents the ingress of moisture and dust into the interior 7 of the guide and protective frame 5, in which the non-molded part of the connector pins 8, 9 is located.
- a plurality of individual depressions in the lateral surface of the carrier 4 and a plurality of corresponding individual projections can also be provided on the inner wall of the guide and protective frame 5.
- the carrier 4 with an external thread and the guide and protective frame 5 partially with an internal thread, so that the carrier 4, which forms a one-piece structural unit with the housing 1 and represents a first component 4, 1, and the guide and the protective frame 5, which represents a second component 5, can be screwed together by screwing the guide and protective frame 5 onto the projection of the housing 1 serving as a carrier 4 for the plug pins 8, 9.
- the housing 1 is preferably made of a thermoset and the guide and protective frame is preferably made of a thermoplastic.
