Definitions
- the invention relates to a holding frame according to the preamble of independent main claim 1.
- the invention further relates to a method according to the preamble of independent claim 9.
- Such holding frames are required to accommodate several modules that are similar and/or different from one another.
- These modules can be, for example, insulating bodies that are intended as contact carriers for electronic and electrical and possibly also for optical and/or pneumatic contacts. It is particularly important that the holding frame enables proper protective grounding in accordance with the connector standard EN61984, for example for inserting the holding frame equipped with modules into metallic connector housings.
- a holding frame for holding connector modules and for installation in connector housings or for screwing onto wall surfaces is known, the connector modules being inserted into the holding frame and holding means on the connector modules interacting with recesses provided on opposite wall parts (side parts) of the holding frame, the recesses as Openings closed on all sides are formed in the side parts of the holding frame, the holding frame consisting of two hingedly connected to one another There are halves, with the separation of the holding frame being provided transversely to the side parts of the frame, and with joints in the fastening ends of the holding frame being arranged in such a way that when the holding frame is screwed onto a fastening surface, the frame parts align themselves in such a way that the side parts of the holding frame are perpendicular to the Fastening surface are aligned and the connector modules have a positive connection to the holding frame via the holding means.
- such holding frames are usually manufactured in a die-casting process, in particular in a zinc die-casting process.
- the publication EP 2 581 991 A1 discloses a holding frame for connector modules, which has two frame halves, which can be locked together in a sliding direction by linearly displacing one frame half relative to the other frame half, with mutually corresponding locking means being provided on the frame halves, which lock the two frame halves together in two during linear displacement cause different locking positions in which the frame halves are spaced at different distances from one another.
- such holding frames require complex operation during assembly.
- such holding frames must be unscrewed and/or unlocked from the connector as soon as even a single module is to be replaced.
- the other modules that were not intended to be removed may also fall out of the holding frame and then have to be reinserted before screwing together and/or before locking the frame halves.
- all modules must be in their intended position at the same time in order to be finally fixed in the holding frame when the frame halves are joined together, which makes assembly more difficult.
- 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 designed as a circumferential collar and has several wall segments separated by slots on its plug-in side. Two opposite wall segments each form an insertion area for a plug module, the wall segments having window-like openings which serve to accommodate projections formed on the narrow sides of the modules.
- a guide groove is provided in each of the wall segments. The guide groove is formed above the openings by means of a window bar that is offset outwards and has an insertion bevel on the inside.
- the plug-in modules have locking arms, which are formed on the narrow sides in the direction of the cable connections and lock below the side collar wall, so that two independent locking means fix the connector modules in the holding frame.
- the plastic material and the shape, in particular the strength of the holding frame are primarily determined at the relevant points by the requirements for flexibility and not by those for temperature resistance.
- the object of the invention is to provide a design for a holding frame which, on the one hand, has good heat resistance and high mechanical robustness and which, in particular, also has a corresponding protective earth, in particular a PE ("Protection Earth”), when installed in a metallic connector housing. and which, on the other hand, also ensures comfortable operation, especially when replacing individual modules.
- a PE Protection Earth
- Such a holding frame can be used in the area of heavy industrial connectors and can at least partially consist of an electrically conductive material. This makes possible protective grounding if necessary, which can be implemented, for example, by the holding frame having a PE contact or at least being equipped with such a PE contact.
- the holding frame has a base section and a deformation section, which are at least partially formed from different materials.
- the base section is used to fix a recorded module in a plane.
- the deformation section can assume an insertion state and a holding state, wherein the insertion state allows insertion of at least one module in a direction transverse to the plane into the holding frame, with a received module being fixed in the holding state.
- the holding frame can, for example, have a base frame as a base section and at least one, preferably two cheek parts as a deformation section.
- the base frame can then be made of a different material than the cheek parts and thus advantageously have less elasticity and therefore greater rigidity than the cheek parts.
- the deformation section in particular the cheek part or parts, can be formed from a material which, according to its stress/strain diagram, is more elastic, i.e. has a smaller modulus of elasticity, than the material from which the base section, in particular the base frame, is formed.
- the material of the base section can be stiffer than the material from which the deformation section is formed.
- the material of the base frame can have a modulus of elasticity corresponding to its stress/strain diagram, which is greater than the modulus of elasticity of the material from which the cheek parts are formed.
- the magnitude of the elastic modulus is greater the more resistance a material offers to its elastic deformation.
- the material from which the deformation section is formed can, according to its stress/strain diagram, have a larger elastic range than the material from which the base section is formed.
- the base section in particular the base frame, can be designed to be rigid, in particular rigid when viewed in an idealized sense.
- the deformation section in particular the cheek part or cheek parts, can be designed to be resilient and can advantageously be made from a resilient sheet metal.
- a resilient sheet is to be understood as meaning a sheet that has resilient properties, such as reversible deformability, in particular with the application of a corresponding restoring force, for example a sheet that is made of spring steel or a comparable material.
- An advantage of the invention is that the modules can be inserted into the holding frame and removed from it individually and with very little effort, which makes manual assembly easier in particular.
- the resilient properties of the deformation section, in particular of the cheek part or parts allow modules to be inserted or removed individually with very little effort.
- the rigidity of the base frame can ensure the necessary mechanical stability when holding the inserted modules.
- the use of one or more metallic materials ensures a high temperature resistance, compared to plastic, for example, and also a particularly high mechanical robustness of the holding frame.
- a further advantage of using one or more metallic materials is that the holding frame enables protective grounding, in particular PE protective grounding, of a metal connector housing into which the holding frame is inserted for electrical safety. As an additional advantage, this also ensures shielding of the signals transmitted through the connector.
- This shielding can provide protection against external interference fields. However, it can also be a shield to avoid or reduce interference emissions, i.e. to protect the environment against interference fields from the connector. In other words, not only are the signals transmitted by the modules protected from external interference fields, but the environment is also protected from interference caused by a current flow that runs through the modules.
- a particularly great additional advantage of using one or more metallic materials is that the holding frame is, on the one hand, particularly heat-resistant and, on the other hand, still has a sufficiently high level of elasticity at the required points, for example through the use of resilient sheet metal, to hold the modules individually and can be inserted into the module frame and removed again with little effort. It is therefore particularly advantageous if the holding frame has spring-elastic sheet metal in suitable places, because this means that it is much more heat-resistant than one with at least as much elasticity From a mechanical point of view, otherwise functionally comparable plastic frame.
- Associated modules can be designed to be correspondingly compact in design, so that they can still be made of plastic and are still relatively heat-resistant.
- the holding frame has several different areas, for example a first and a second area, which have different elasticities from one another, because it can then specifically apply a higher moment of resistance in the area of the highest bending stress.
- the first area can correspond to the basic section.
- the second area can correspond to the deformation section.
- These different areas can, for example, be formed from different materials and thus preferably have different material properties, in particular different moduli of elasticity.
- the second region in particular the deformation section, can therefore have a higher elasticity than the first region, which corresponds in particular to the base section.
- the first area can therefore have greater rigidity than the second area.
- the first region can be designed to be rigid and the second region can be designed to be resilient.
- Such elasticity or rigidity can, on the one hand, as already mentioned, be achieved by the material used in each case and/or, on the other hand, it can also be achieved by the geometric shape of these areas, in particular the base section and the deformation section.
- the first area in particular the base section, can be formed from a rigid material, for example from a zinc alloy or made of an aluminum alloy or a copper alloy.
- the second region, in particular the deformation section can be formed from a resilient material and thus consist, for example, of a resilient steel sheet.
- the first area, in particular the base section can be produced in a casting process, for example in a zinc die-casting or aluminum die-casting process, or can also be produced by milling from, for example, a copper alloy.
- the first region, in particular the base section can preferably be the circumferential base frame.
- the base frame can therefore in particular be a zinc die-cast part.
- the base frame can be essentially rectangular in cross section, i.e. it has two end faces lying parallel to each other and two side parts lying parallel to each other at right angles thereto, the two end faces being shorter than the two side parts. Both the end faces and the side parts can have a substantially rectangular shape.
- the second region in particular the deformation section, can be formed, for example, from at least one, preferably two, separate cheek parts, of which each cheek part preferably consists of a resilient sheet metal part.
- the two cheek parts can optionally be made of the same material, in particular spring-elastic sheet metal, and can also have the same thickness.
- the two cheek parts can preferably be punched out of the same punching sheet.
- Each cheek part can be essentially flat and preferably have a rectangular basic shape. It therefore has two long edges lying opposite each other, namely a first and a second edge, and at right angles thereto two opposite short edges, namely a third and a fourth edge.
- the cheek part has, in particular, preferably rectilinear slots which begin at regular intervals on its first edge and preferably extend into the cheek part at right angles thereto in the direction of the second edge, whereby free-standing tabs are formed in the cheek part.
- a latching window can be arranged as a latching element in each of these tabs. These locking windows are intended to accommodate locking lugs of inserted modules in order to lock the modules in the holding frame.
- each cheek part can have several fastening elements, in particular fastening recesses in a preferably round shape, for fastening to the base frame.
- Each of the two cheek parts can advantageously be attached to the base frame on an outer side of one of the two side parts, so that two resilient tabs of the two cheek parts are symmetrically opposite each other. Furthermore, these tabs can be bent slightly outwards towards their end, i.e. away from the base frame and thus away from each other, in order to make it easier to insert a module.
- the base frame can have fastening means, for example round fastening pins. These fastening means can engage in the fastening recesses of the associated cheek part and hold the cheek parts on the base frame, for example by latching and/or by means of a positive and non-positive connection. Additionally or alternatively, the cheek parts can be attached to the base frame by gluing, welding, soldering, riveting and/or screwing or by any other type of fastening to the base frame.
- fastening means for example round fastening pins.
- the associated modules can be essentially cuboid-shaped and can each have a width on two opposing end faces that corresponds to the width of a tab.
- Each module advantageously has a locking lug on its two end faces, which can also be essentially cuboid.
- Each of the spring-elastic tabs of the holding frame advantageously has a locking window, which can be essentially rectangular and which is intended for the preferably positive reception of such a locking lug.
- the two locking lugs of a module can differ from one another, for example in their shape and/or their size, in particular in their length, and the tabs on both sides of the holding frame can have corresponding windows, which also differ from one another and in their size and/or their shape matches one of the locking lugs.
- This has the advantage that the orientation of each module in the holding frame is fixed.
- the latching windows and the latching lugs can be used as coding means, in particular as polarization means, for orienting the modules in the holding frame due to their shape and/or size.
- the tabs of the holding frame are slightly bent away from the holding frame in a free-standing end region, which simplifies the insertion of the modules. Inserting a module into the holding frame is then particularly user-friendly.
- a module is first inserted between two tabs of a holding frame and then slides with its two end faces and in particular with the locking lugs formed thereon along the end regions of the tabs that are bent away from one another.
- the two tabs bend apart for a short time until the respective locking lugs are received by the associated locking window of the respective tab and thus lock into it.
- the tabs preferably spring back into their starting position. In this way, the modules can be locked individually in the holding frame.
- the module is held firmly in the preferably rigid base frame.
- the respective module can then be removed individually from the holding frame, while the other modules continue to be locked. This ensures that the module is firmly held in the holding frame with a comparatively low actuation force, which is particularly advantageous for operability.
- the modules are already held in the holding frame with sufficient holding force by the aforementioned construction and therefore do not require any other locking means, for example locking arms, apart from their locking lugs, because this considerably simplifies their design and thus their manufacturing effort and at the same time ensures a compact design and therefore also for high heat resistance of the modules and thus the entire connector.
- these two cheek parts are of the same type, i.e. despite the two-part design of the holding frame, only cheek parts of one type have to be produced, which further reduces the manufacturing effort.
- the two cheek parts differ in the size and/or the shape of their locking windows. This has the advantage that it determines the orientation of each module, which accordingly also has two different locking lugs is. In other words, the locking windows and the locking lugs can therefore serve as coding means for orienting the modules due to their shape.
