  • such holding frames are usually produced in a die-casting process, in particular in a zinc die-casting process.
  • the publication EP 2 581 991 A1 discloses a support frame for connector modules having two frame halves which are latched together by linear displacement of a frame half relative to the other frame half in a sliding direction, wherein mutually corresponding locking means are provided on the frame halves, the latching of the two frame halves effect each other in two different locking positions during linear displacement, in which the frame halves are spaced at different distances from each other.
  • such mounting frames require a complex operation during assembly.
  • such support frame must be unscrewed from the connector and / or unlocked as soon as a single module to be replaced. In this case, possibly fall the other modules whose removal was not desirable, out of the support frame and must then be reinserted before screwing together and / or before locking the frame halves.
  • you need to be aware before joining the frame halves all modules are simultaneously in their intended position to be permanently fixed in the mounting frame when joining the frame halves, which makes mounting difficult.
  • the publication EP 2 228 871 A2 describes a connector with a body consisting of an insulator; a plurality of metal-made contacts held by the body; and a shield cover made of a metal plate.
  • the publication DE 27 36 079 A1 discloses a latchable terminal block or connection module for electrical leads, the terminal block being provided at its two end edges which run parallel to the longitudinal direction of a support rail for assembling such terminal blocks with grooves respectively co-operating with internal horizontal projections close to the free one Ends of the two legs of a metallic U-shaped carrier profile are provided, wherein the grooves can be used at different distances from the bottom of the profile against the action of at least one transverse leaf spring.

  • the plug-in modules can be used against previously common arrangements in connectors on both sides, ie in the insertion direction or against the insertion direction in the support frame and removed again.
  • the publication WO 2008 121 092 A2 discloses a frame for multi-pin connector, consisting of a flange and an insertion part with lamellae formed thereon, which are formed from the bottom waste piece of the insertion part at its free end edge and bent onto the wall of the insertion part
  • the publication EP 1 801 927 B1 discloses a holding frame, which consists of a one-piece plastic injection molded part.
  • the holding frame is formed as a circumferential collar and has on its side plug a plurality of separated by slots wall segments.
  • Two opposite wall segments each form an insertion region for a plug-in module, wherein the wall segments have window-like openings, which serve to receive projections formed on the narrow sides of the modules.
  • a guide groove is provided in the wall segments.
  • the guide groove is formed above the openings by means of an outwardly offset window web, which has an insertion bevel on the inside.
  • the plug-in modules have latching arms, which act on the narrow sides in the direction of the cable connections, molded, and latch below the side collar wall, so that two independent locking means fix the connector modules in the support frame.
  • a disadvantage of this prior art is a holding frame formed of plastic, which is not suitable for protective grounding, for example by a PE contact, so for example not suitable for installation in metallic connector housing.
  • the use of metal connector housing sets such a protective ground however, and in many cases is necessary and therefore desired by the customer because of their mechanical robustness, temperature resistance and electrically shielding properties.
  • the production of such trained plastic holding frame by injection molding is at least difficult and re-al Budapest.
  • the heat resistance of such a support frame for special applications for example in the vicinity of a blast furnace, is not always sufficient.
  • the plastic material and the Shape in particular the strength of the holding frame in the relevant places primarily determined by the requirements of the flexibility and not those of the temperature resistance.
  • the object of the invention is to provide a design and a manufacturing method for a holding frame, which on the one hand has good heat resistance and high mechanical robustness and in particular also when installed in a metallic connector housing a corresponding protective ground, in particular a PE ("Protection Earth”) - Protective ground, allows and on the other hand, a comfortable operation, especially when replacing individual modules guaranteed.
  • a PE Protection Earth
  • Such a support frame is used in the field of heavy industrial connectors and consists at least partially of a metallic material, namely sheet, thus a protective ground, in particular a PE protective earth, allows, and at the same time allows due to the elastic properties of the sheet, modules individually with only very little effort to insert or remove. Furthermore, the use of sheet metal as a material ensures high temperature resistance and also ensures a particularly high mechanical robustness of the holding frame.
  • a resilient sheet is to be understood as meaning a sheet which has spring-elastic properties, such as, for example, a reversible deformability, in particular with the application of a corresponding restoring force, ie, for example, a sheet metal made of spring steel or a comparable material.
  • An advantage of the invention is therefore that the modules can be inserted individually and with very little effort in the support frame and removed from it.
  • the modules have a cable connection side which is intended to be connected to a cable, e.g. by screwing, crimping, soldering or the like, and that the modules are inserted from the direction of their cable connection side in the support frame, because they can be completely removed in the wired state of the support frame back towards their cable connection side.
  • a connector housing such as a Flanschanbaugephaseuse.
  • Another advantage therefore also lies in the fact that the cable can be prefabricated with the modules and, independently of the process of prefabrication, can only later be inserted into a holding frame. Also, the support frame can be replaced in this way, without the need to be separated from the cable modules, e.g. if the holding frame has wear and / or damage.
  • the holding frame for electrical safety a protective ground, in particular a PE protective ground of a metallic connector housing, in which the holding frame is inserted, allows.
  • This shielding can be a protection against interference from the outside act. But it can also be a shield to prevent or reduce an interference emission, so protect the environment against interference fields of the connector. In other words, not only are the signals transmitted by the modules protected from external interference fields, but environmental protection from disturbances also takes place, which is caused by current flowing through the modules.
  • the support frame is on the one hand particularly resistant to heat and on the other hand still has sufficient elasticity at the required points to insert the modules individually and with little effort in the module frame and remove again. It is particularly advantageous if the entire holding frame (or at least the functional part of the holding frame for holding and fixing the modules) consists of resilient sheet metal, because it is substantially more resistant to heat at least as great elasticity than a mechanical point of view otherwise functional comparable plastic frame. Associated modules can be made compact in their design accordingly, so that they can continue to be made of plastic and still are relatively resistant to heat.
  • both the material and the design of these modules need to show only low elasticity, because even the holding frame consists of a resilient sheet and therefore, for example, is able, the modules in a constant base voltage over a To keep longer period, without thereby fundamentally changing, for example without so much irreversible deformation and especially under constant mechanical and thermal stress to "crawl" so strong that its holding force with respect to the modules and / or for example, the Contact pressure to a mating connector and thus the optimal function of the connector would be called into question.
  • the modules can be resiliently clamped in the holding frame without the modules themselves having to have elastic parts and / or material properties.
  • the holding frame is at least partially made of resilient sheet metal, so at least partially consists of one or more resilient sheet metal parts.
  • the holding frame can be produced in stamping and bending technology, so that the sheet metal part or parts are stamped and bent parts.

  • the holding frame consists of several stamped and bent parts, then these stamped and bent parts can consist of the same sheet metal and accordingly have the same material properties, in particular the same elasticity to one another. But they can also be punched out of different sheets and have different material properties, in particular different strengths and / or elasticities.
  • the holding frame has a plurality of different areas, which have a different elasticity to each other, because then he can selectively apply a higher moment of resistance in the region of the highest bending stress.
  • the first region with a higher resistance moment is thus a base section.
  • the second region with a lower resistance moment is a deformation section.

  • the base frame may be substantially rectangular in cross-section, thus having two mutually parallel opposite end portions and perpendicular thereto two mutually parallel opposite side parts, wherein the end portions are shorter than the side portions. End and side parts can also be the same length in the special case of a square cross section.
  • this closed shape already contributes to the geometry of the base frame and thus the geometry of the entire support frame that this first area, namely the base frame, a lower elasticity and thus greater strength than a second area, which for example from a cheek area with free-standing elastic tabs, which are separated by slots.

  • the two locking lugs of a module may, for example, in their shape and / or size, in particular by their length, differ from each other and the tabs on both sides of the support frame may have corresponding (eg rectangular) windows, which therefore also differ from each other and which fit in size and / or shape to each one of the locking lugs.
  • This has the advantage that thereby the orientation of each module is fixed in the holding frame.
  • the latching window and the locking lugs can be used by their shape and / or size as coding means for orientation of the modules in the holding frame.
  • the tabs of the holding frame are advantageously bent away easily in a free-standing end portion of the support frame, which simplifies the insertion of the modules.
  • the insertion of a module into the holding frame is then particularly user-friendly.
  • a module is first introduced between two tabs of a holding frame and then slides along with its two longitudinal sides and in particular with the locking lugs formed thereon along the bent away end regions of the tabs.
  • the two tabs bend momentarily further apart until the respective latching noses are received by the associated latching window of the respective tab and thus, in particular audibly, lock into it.
  • the tabs When receiving the locking lugs in the respective locking window, the tabs preferably spring back into their starting position. In this way, the modules individually in the holding frame, preferably audibly, lock.

  • the manufacturing advantages of the stamping and bending technique can be combined with a targeted influencing of the elasticity, which is otherwise difficult to implement, in particular if the same stamped sheet is used, which originally has a constant thickness.
  • a resilient sheet can be used as a particularly suitable material for the holding frame
  • the elasticity of individual areas of the holding frame can also be selectively influenced in the manner described above, using a single stamping sheet, which facilitates the production.

  • the tabs are still preferably formed in contrast to the base frame of only a single, unreinforced sheet, so are not reinforced by a second plate, and thus have only the simple strength of this single sheet and thereby a greater elasticity than the first area.

  • the tabs have a high elasticity against outward-acting forces, while the side parts in the region of the base frame oppose outward forces a great stability, since they are reinforced by the reinforcing regions. Since the tabs are connected to the side surface only by the reinforcing region on the common bending edge, they spring outwardly unreinforced over their entire length, whereas the side surfaces against outward forces by the reinforcing regions, and thus in particular by a corresponding overlap region of the tabs, are reinforced.
  • each end face can be reinforced, for example, by stamping in each case additionally a reinforcing surface adjacent to each end surface during the blanking of the sheet, which is then bent by 180 ° and thereby folded over the end face in order to reinforce it and thus stabilize the base frame additionally.
