Definitions
- the invention relates to a device unit with a contact device for releasable connection to stationary busbars, with a contact unit which has contact elements interacting with the busbars and connection means for the electrical connection of the contact units with switching, control and protective devices belonging to the device unit.
- a contact housing made of insulating material with chambers for receiving the contact units
- a device unit with these features is e.g. B. become known from DE 37 29 454 C3.
- the contact housing has edge webs which rest on the edge of the opening of a frame or housing of a device unit. Through holes in the edge webs are used to attach the contact device to the frame or housing.
- the contact device can be inserted into the opening from the outside or from the inside for mounting and fastening. The result of this is that either the forces that occur when the contact device is plugged onto the field rails or the forces that occur when the field rails are separated are transmitted via the edge webs. The forces acting in the opposite direction are then transmitted via the fastening means.
- the object of the invention is to facilitate the installation of the contact device in a device unit and to keep the stress on the contact housing low by the plug-in and release forces.
- This object is achieved according to the invention in that on at least two opposite sides of the circumference of the contact housing two edge webs are arranged parallel to one another and at a mutual distance and - that the edge webs capture the wall from both sides, such that the contact device both against Forces when plugging onto the busbars as well as against forces in the separation thereof is supported.
- Fastening means for absorbing or transmitting plug-in and release forces of the contact device are therefore unnecessary and are essentially only required as a position securing device for the contact device on the wall mentioned.
- the support device for the contact device is formed according to the aforementioned DE 37 29 454 C3 by a wall which has an opening for inserting the contact housing.
- further designs of the support device are proposed which facilitate the assembly of the contact device and improve its support.
- the support device comprises at least two support members parallel to opposite sides of the circumference of the contact housing, of which the one support member is an integral part of a housing of the device unit and of which the second
- Support member is designed as a detachable to the housing holding bridge.
- the fixed support element belonging to the housing of the device unit can be designed as a wall with a passage opening having two sections, of which the first section for the passage of the contact housing including its edge webs is expanded and the second section is adapted to the dimensions of the contact housing. This ensures that the wall of the device unit, the contact housing is detected on three sides of its circumference and only the remaining fourth side cooperates with the retaining bridge.
- the embodiments of the invention explained above are suitable for both plug-in and insertable device units. If these are provided with contact devices for the infeed and exit side, the support members for both contact devices can be of the same design or can be common.
- a design is particularly suitable for pluggable device inserts in which - the housing of the device unit has a rear wall with an upper wall angled at right angles thereto, the passage opening extends over the upper wall and the rear wall, such that the first section of the passage opening extends in the upper one Wall and the second section is located in the rear wall, and the retaining bridge for engaging over the upper wall and the rear wall is angled.
- the contact housing Although it may be sufficient to provide only two opposite sides of the circumference of the contact housing with edge webs, it is advisable to arrange parallel edge webs on all four sides. There are several possibilities per se for providing the contact housing with parallel edge webs or for producing contact housings provided with such edge webs. For the desired uniform distribution of the insertion and release forces in the contact housing, it would be most favorable if the edge webs form a ring which is closed on the circumference of the contact housing. In order to be as simple and inexpensive to manufacture as possible, however, it is possible to manufacture the contact housing as one piece as a plastic molded body, which is difficult with closed edge webs.
- the edge webs are designed as projections of the contact housing which are successively arranged with an intermediate space, the projections being offset from one another in the parallel edge webs, this arrangement has the property that the projections into the plastic injection mold as Features that extend in the demolding direction can be incorporated. This significantly simplifies the design of the injection mold.
- the one support member can be part of walls of a housing of the device unit that are at right angles to one another.
- This design can be supplemented by the fact that the housing has a further lower wall which is angled in the same sense and, together with a device support plate, encloses a cuboid cavity which receives the contact device.
- This also creates the possibility of protection against accidental contact for connecting terminals of the contact device, specifically by connecting terminals of the contact units protruding from the contact housing being protected by a terminal cover made of insulating material, which is held on the upper and lower walls.
- Such a terminal cover can be approximately U-shaped in the context of the invention can be formed and can have legs which extend above and below the contact device, a central part of the clamping cover (25) parallel to the rear wall of the device unit being provided with retaining tongues which engage in slots in the upper (7) and lower wall.
- FIG. 1 shows a device unit designed as a pluggable device insert with a contact device according to the invention in a perspective view with a view of contact elements arranged on the rear.
- FIG. 2 shows a device insert, each with a contact device for the feed and the output.
- FIGS. 3 and 4 show a contact device of the device units according to FIGS. 1 or 2 separately in a top view or in a section IV-IV.
- FIG. 5 shows an end view of the device unit according to FIG. 1.
- FIG. 6 shows a housing of the device unit according to FIG. 1 without an associated device support plate and with a terminal cover shown pulled out.
- the device unit 1 has a box-like housing 2, switching, control and protection devices 3 and a contact device 4.
- the housing 2 has a support device 5 for the contact device 4 and a device support plate 6, wherein the rear part of the housing 2 has three right angled wall parts in the same sense, namely an upper wall 7, a rear wall 8 and a lower wall 9.
- the device support plate 6 is at its upper edge on support tabs 10 of the upper wall 7 and fixed at their lower edge by lugs 11 which engage in slots 12 of the lower wall 9.
- the housing 2 is preferably made of sheet steel.
- the contact device 4 is of three-pole design and accordingly has three contact units 13. These contact units 12 are received in a contact housing 14, which consists of an insulating plastic and has four chambers 15 for receiving contact units. In the example shown, three of these chambers 15 are equipped with contact units 13, while the remaining chamber 15 is empty.
- the contact units are the subject of a patent application with the designation "contact device for the detachable connection of a movable device unit with fixed busbars" with the same filing date as the present deregistration. In the present context, the contact device 4 is therefore only described as far as the contact units are necessary to understand the invention. In particular, it should therefore be mentioned that the contact units 13 have fork-like contact elements 16 aligned with the busbars 30 indicated in FIGS.
- connection of the connecting rails 17 to the devices 3 takes place in a known manner by means of flexible cables or shaped conductors, which have been omitted from the figures for the sake of simplicity.
- the contact units 12 are connected to the contact housing 14 in such a way that they counteract the th busbars and when separating from these forces are supported.
- the contact housing 14 is provided on four sides of its circumference with edge webs 18, as can best be seen from FIGS. 3 and 4. It is essential here that the edge webs 18 are formed by two parallel rows of projections 19 which are arranged at a distance corresponding to the thickness of the rear wall 8.
- the rear wall 8 thus forms a component of the support device 5.
- the rear wall 8 is provided with a passage opening 20 which has a first section 21 located in the upper wall 7 and a second subsequent section 22 located in the rear wall 8.
- This passage opening 20 or its sections 21 and 22 ensures that the contact device 4 can be inserted into the box-like housing 2 and the lower edge and the lateral edges of the section 22 between the projections 19 of both edge webs 18 be included.
- three of the four peripheral sides of the contact housing are already.
- the contact device 4 is shown broken off on the right in FIG.
- the projections 19 of the edge webs 18 are arranged offset with respect to one another, namely without mutual overlap. This has no influence on the transmission of forces between the contact device and the box-like housing 2, but has significant advantages for the production of the contact housing 14.
- the offset of the projections 19 in fact allows the projections to be included in two partial molds for plastic injection molding (injection molding), so that the contact housing 14 can be manufactured inexpensively despite numerous design features.
- the device unit 1 contains a terminal cover 25, which can be seen in more detail in FIGS. 5 and 6. Thereafter, the terminal cover 25 is angled approximately in a U-shape and has a central part 26 and legs 27 extending therefrom. At the ends of the central part 26, holding tongues 28 are arranged in the plane thereof, into corresponding slots 29 in the upper wall 7 and the lower wall 9 of the box-like housing 2 are arranged. As FIG. 6 in particular shows, the distance between the legs 27 corresponds to the distance between the upper wall 7 and the lower wall 9. The length of the legs 27 is also dimensioned such that the connecting rails 17 and the part of the contact housing lying in the interior of the housing 2 14 enclosed or covered.
- the terminal cover 25 consists of an electrically insulating plastic and can preferably be produced from a plate-shaped material which can be bent or edges (ie without the application of heat) can be processed. Due to the flexibility of the plastic, the retaining tongues 28 can be snapped into the slots 29, although the entire height of the clamping cover 25 exceeds the distance between the walls 7 and 9 of the housing 2.
- the described contact device 4 is characterized in that its components are easy to manufacture and can be easily assembled.
- a connects comes d ü ng between the housing 2 of the unit 1 and the entire periphery of the contact device 4 about.
- the holding bridge 23 has mainly the function of securing the position of the contact device 4, since it only covers one of the four circumferential sides of the contact housing 14. By designing the wall 5, the terminal cover 25 can be reliably attached without tools.
- the further exemplary embodiment of a device unit 31 according to FIG. 2 corresponds in all essential details to the above description.
- it is a drawer unit provided with a contact unit 32 for connection to feeding busbars (corresponding to S tromschienen 30 in Figures 3, 4 and 6) and a further contact unit is provided for the output of the display unit 3 1 33rd
- the contact units 32 and 33 are arranged side by side and correspond also in all essential details' of the detail described above Contact unit 4 with the difference that each pole are three contact elements 16 are provided, to increase the current carrying capacity.
- the equipping of the contact housing 14 of the contact unit 33 with contact units 13 is selected as a mirror image of the contact unit 32, ie instead of the left-hand cam mer 15 ( Figures 4 and 6), the right chamber 15 is left free.
- the device unit 31 has a support device 34 with one corresponding to the support device 5 in FIG. 1
- the support device 34 comprises a rear wall 35 belonging to the device unit 31, which is adapted to the contact housings 14 with their edge webs 18 or projections 19. Furthermore, the support device 34 includes a holding bridge 36, which is similar to the holding bridge 23 described above, but is designed to be longer in order to detect both contact devices 32 and 33 together. Fastening elements 37 connect the holding bridge to a frame-like housing 38 of the device unit 31.
- the device unit 31 in FIG. 2 is shown schematically like the device unit 1 in FIGS. 1 and 3 to 6 without wiring.
- switching, protective and control devices 3 are mounted on a support plate 39 in the housing 38 in a known manner, the input of which is connected to the connecting rails 17 of the contact device 32 and the output of which is connected to the corresponding connecting rails 17 of the contact device 33 ,
- the space between the support plate 39 and the contact devices 32 and 33, which can be seen in FIG. 2, serves to accommodate the necessary cables and lines. LIST OF REFERENCE NUMBERS
