Definitions

  • the invention relates to a kit for an encapsulated electrical installation device of the type mentioned in the preamble of claim 1.
  • kits which consist of relatively few groups or parts, but which can be combined into a relatively large number of variants.
  • Installation devices essentially consist of a lower housing part, an upper housing part and a device insert. While the upper part of the housing and the device insert usually have to be adapted to the respective type of installation device and can therefore only be brought into a similar shape to a limited extent, the lower part of the housing can be designed uniformly for all or many variants with a clever construction. The number of possible variants can be reduced by combining the alternative connection techniques of screw and snap-in connection that are required in one housing.
  • the lower housing part must also be designed so that it is suitable for receiving various types of equipment inserts and upper housing parts, the latter of course also having to be adapted accordingly.
  • Locking devices with locking levers and locking pads generally meet this requirement much better than screw devices. However, the latter are preferred in exceptional cases.
  • a moisture-proof housing for electrical installation devices is known (DE-GM 7 223 172), which is provided with a device for fastening the cover, which permits both a latching and a screw connection.
  • the connecting device is located in the middle of the housing, which is structurally disadvantageous. At least when the housing is also used to hold z. B. to serve a toggle switch, very considerable design difficulties are to be overcome.
  • support columns are formed in the lower housing part.
  • the support columns give the device insert a distance from the housing base, so that there is space for the cable routing underneath the device insert.
  • This device works with a locking device, but this is only used to attach the device insert to the lower part of the housing. How to connect the upper housing part to the lower housing part can not be found in the document.
  • the object of the invention is to provide a kit of the type mentioned in the preamble of claim 1, which allows easy assembly and detachment of its parts and in which individual parts are adapted to their respective intended use (switch, socket, etc.), but otherwise parts of the same type, in particular lower housing parts, as far as possible are of the same design.
  • Either (flexible) thermoplastics or non-flexible, but scratch-resistant thermosets are used as injection molding material for the housing of installation devices. While the locking device can be molded onto a housing made of thermoplastic, a locking lever made of flexible thermoplastic or metal should preferably be attached to the housing in a housing made of thermosetting plastic. These very different conditions have to be taken into account when designing the lower part of the housing.
  • Guide pins which are provided with a groove that is suitable for inserting a locking lever, are used to install the locking levers in a thermoset housing. It is essential that the locking levers serve as guide elements for the use of the device, regardless of the housing structure. At the same time, they are supported on the guide groove of the device insert, so that only that part of the latching lever which projects beyond the guide groove can execute a resilient movement.
  • the locking levers molded onto the housing are disruptive. This is not least because the locking levers must penetrate the seal between the housing parts. In the case of watertight housings, this could mean a reduction in the tightness. It is therefore advantageous to provide the locking levers in the region of the guide groove with a predetermined breaking point which allows the locking levers to break out.
  • the locking lever should be attached to a housing made of duroplastic as easily as possible.
  • a foot can be formed on the locking lever, which encloses part of the base arranged in the housing in a cap-like manner.
  • a pin formed in the area of the locking lever foot serves for welding and thus inseparable connection of the two parts.
  • the highly elastic seal between the two housing parts offers the great advantage that the upper housing part can be removed from the lower housing part with one hand. As soon as one of the two latches is released, the highly elastic seal pushes the two housing parts apart. First of all, the upper part of the housing thereby tilts to the lower part of the housing, withdraws after the Ausklin ken of the second or further locking lugs, however, completely the engagement of the locking device.
  • the funnel-like design of the latching receptacles continues the separation of the two housing parts initiated by the elastic seal.
  • the sliding surface of the locking lug which is adapted to the wall slope, also contributes to this.
  • the locking lugs pushing back into their initial position by spring action push the upper housing part away from itself via their sliding surfaces.
  • either a separate seal or a seal molded onto the housing parts can be used to seal the separation gap between the two housing parts.
  • a molded seal must be designed so that a large spring travel can be realized with it. This is achieved with a seal that projects over the load-bearing side walls of the housing part inwards and / or outwards as a sealing lip. At least one sealing edge of the other housing part is supported on the sealing lip.
  • the locking receptacles lie in a cover plate formed in the upper part of the housing.
  • the latch that can be released from above is surrounded by a cover.
  • the cover can only be overcome with the help of a tool.
  • the design of the cover depends on the type of installation device.
  • a toggle switch the rocker to be plugged onto the upper housing part serves as a cover.
  • a collar is provided which surrounds the latching support and thus also the latching opening. There is only a small gap between the collar and the catch, into which only a tool can be inserted.
  • the assembly of the housing is facilitated in that the locking lever and locking receptacles are arranged symmetrically to one another. This enables a rotation of 180 °.
  • FIG. 4 shows an installation switch in section, which consists of a lower housing part 1, an upper housing part 2 and a locking device 4, 5 connecting the two housing parts.
  • a highly elastic seal 3a is inserted between the housing parts.
  • the first task is to seal the housing against the ingress of water. It also compensates for tolerances in the separation gap between the housing parts and thus ensures that the upper housing part is firmly seated.
  • the seal's exceptional elasticity has a decisive effect on the locking device. As soon as the latching device is released, the two housing parts are pressed apart by the seal.
  • a base 8 is formed on the base plate 1 b of the lower housing part 1, on which in turn a pin 9 is formed.
  • the pin 9 is provided with a groove into which a locking lever 4 is inserted.
  • the locking lever 4 also has a cap-like foot 4d, with which it is supported on the base 8.
  • At the head of the locking lever 4 there is a locking lug 4a which is latched in the locking receptacle 5 of the upper housing part 2.
  • the latching lever has a kink 4c, as a result of which the latching nose 4a is somewhat offset from the center of the base 8.
  • the catch receptacle 5 is formed in the cover plate 2a of the upper housing part 2. This consists of a locking opening 5a and a locking support 5b.
  • the funnel-shaped locking opening 5a towards the locking support facilitates the penetration of the locking lever with the locking lug.
  • the sliding surface of the locking lug 4a also has the same inclination as the wall surface of the funnel-like locking opening 5b. As a result, not only is the locking lever easier to penetrate into the locking opening, but also an easier opening of the switch.
  • the detent lever 4 After the detent 4a has been released, the detent lever 4 tries to return to the starting position by means of its spring force. Supported by the inclined planes of the sliding surface and the locking opening, the locking lever presses the upper housing part 2 away from the lower housing part 1. As a result, the locking lever not only supports the separating effect of the seal, but continues it as soon as its travel is exhausted.
  • a rocker 6b is attached to the upper part 2, which also serves as a cover for the locking device.
  • the rocker 6b can only be detached from the upper part of the housing with the aid of a tool, so that opening the housing by hand is not possible.
  • the locking device can be supported by a screw connection 12.
  • the essential parts of the switch shown in FIG. 3 are constructed as in FIG. 4.
  • the design of the seal is different, which in this case is molded onto the housing part as seal 3b.
  • the housing parts must be made of a flexible thermoplastic hen, so that the necessary spring action of the seal can be achieved.
  • the seal 3b is formed on the inner edge of the upper housing part 2 as a sealing lip. When assembling the housing parts, the sealing lip 3b is gripped by an edge 1a of the lower housing part and pushed out of its horizontal position. When the locking device is released, the sealing lip springs back.
  • the locking lever 4 is also molded onto the base 8.
  • a predetermined breaking point 4e makes it possible, if necessary, to break out the locking lever and to connect the housing parts only with screws. Since the predetermined breaking point lies in the area of the guide groove 11a of the device insert 11, the latching lever is supported at this point and thus an undesired breaking off is prevented.
  • the locking receptacle 5 of the upper housing part 2 is surrounded by a collar-like cover 6a.
  • a cover of this type is used when the locking device cannot be covered by the rocker of a switch.
  • the collar 6a is placed so high and so tightly around the latching support 5b that the latching lug can only be reached with the aid of a tool.
  • Fig. 1 the locking pad 5b and the locking lug 4a is visible from above.
  • the locking opening 5a is dimensioned so that the locking lugs 4a can easily penetrate it.
  • the upper housing part 2 has an opening 14, via which the rocker switch 6b is connected to the switch insert.
  • the fulcrums of the rocker of the switch lie on the stub axles 16 and form a connection between the upper housing part 2 and the rocker 6b, which lies within a recess 2c of the upper housing part 2.
  • Fig. 2 illustrates the design of the locking lever 4. It can be seen that the locking lug 4a also tapers upwards on the sides in order to achieve an easier penetration of the locking opening 5a.
  • the foot 4d of the locking lever 4 comprises the base 8 only on one side. On the other side of the base 8, a pin 9 is formed, in the not visible through the cut, the locking lever 4 is inserted. A further pin 8a is formed on the base 8 and penetrates a hole in the base 4d of the locking lever 4. After the locking lever 4 is placed on the base 8, the pin 8a is welded at its end to a pin head 8b.
  • the two housing parts 1, 2 overlap one another on the side walls.
  • the locking pins 4 exert a rotational force on the upper housing part 2, which would lead to a tilting relative to the lower housing part. Due to the leading guidance of the overlapping side walls of the housing parts 1, 2, such canting is avoided and an effortless latching of the housing parts is achieved.
