Description

[0001] “Modular fluid distribution system”

[0002] The invention relates to a distribution system for fluid lines, in particular for compressed air brake systems of motor vehicles, comprising a distributor body with at least three connection points for connecting fluid lines, wherein all connection points are fluidically connected to one another via a fluid channel in the interior of the distributor body.

[0003] The invention also relates to distributor bodies, plug inserts and a closure part for such a distributor system.

[0004] Distribution systems for fluid lines are generally known. These typically comprise a tubular, rail-shaped, or plate-shaped distributor body with a defined maximum number of connection points for connecting fluid lines. The connection points are designed for a defined connection type, particularly as screw or plug-in sections.

[0005] Such distribution systems have the disadvantage that they are not very flexible in their use. In order to cover many different fluid distribution applications with different numbers of connection points and / or different connection types of fluid lines to be connected, such as flaring, screwing or riveting, a relatively large range of distributor bodies must be available which vary in the number or connection type of the connection points. This causes relatively high manufacturing and storage costs. On the one hand, the number of pieces per individual part is relatively small and thus the costs per piece are relatively high, and on the other hand, the space required for storing a relatively large number of different parts is relatively large. This advantage is the shorter design of the distributor with the closure part according to the invention and that the closure plugs can now be installed on the same side when several distributors are coupled.Due to the external locking of the old locking parts, the locking parts could previously only be arranged alternately, as can be seen in Figure 1.

[0006] We've attached a drawing of this. If this isn't sufficient, we can create another one.

[0007] It is also known from the prior art to close the fluid channel of such distribution systems at the front with closure parts that can no longer be removed and which rust by means of locking means that cannot be removed without destruction in the inner circumferential wall of the fluid channel.

[0008] The invention is based on the object of providing a distribution system for fluid lines that can be flexibly adapted to a large number of different fluid distribution applications and at the same time can be provided as cost-effectively as possible.

[0009] The object is achieved according to the invention by a distributor system according to claim 1 or claim 11 or claim 23 or a distributor body according to claim 33, plug inserts or bridge plug inserts according to claim 34 and claim 35, and a closure part according to claim 36.

[0010] In a preferred embodiment, the connection points in the distributor body are each designed as a transverse bore running transversely through the fluid channel for inserting plug-in inserts, wherein a plug-in insert is inserted into each of the transverse bores, wherein the plug-in insert has a functional section with fluidic functional means at one end and a holding section with holding means at the opposite end and, in between, a flow section with a flow opening and with sealing sections that fluidically seal the flow opening in the direction of the holding section and in the direction of the functional section with respect to the transverse bore, so that the distributor system can be flexibly configured by simply inserting different plug-in inserts and can be adapted to the respective distributor application or to the respective fluid line system.The distributor body is independent of the connection type and can therefore be used for many different fluid line systems by inserting the appropriate plug-in inserts.

[0011] Preferably, the functional elements of at least one plug-in insert are designed as a plug-on mandrel, push-to-connect coupling, plug-in coupling, closure, or test valve. This allows for easy connection of fluid lines and a flexible functional design of the distributor body.

[0012] Advantageously, the holding sections of the plug-in inserts have at least two radially inwardly elastically deformable locking arms as holding means, which are designed such that they are radially compressed when inserted into the transverse bore of the distributor body, reach through the transverse bore when fully inserted in the distributor rail, expand radially elastically outside the transverse bore and are fastened to the outer wall of the distributor body. The connection points are preferably designed symmetrically such that a plug-in insert can be inserted from one side of the transverse bore as well as from the other side of the transverse bore. This enables particularly simple fastening of the plug-in inserts in the distributor body and permits equipment to be fitted on both sides of the distributor body, thus enabling available installation space or flexible positioning of the fluid lines within the installation space.

[0013] In particular, the transverse bores of the connection points in the area of ​​the outer wall of the distributor body form cylindrical sealing surfaces of the transverse bore. Preferably, a sealing section with a circumferential seal is arranged between the functional section and the flow section of the plug inserts and between the flow section and the holding section of the plug inserts. The sealing section of the plug insert interacts sealingly with the sealing surface of the transverse bore. In particular, a circumferential extension is formed at the transition from the functional section to the adjacent sealing section, which limits the insertion depth of the plug insert into the transverse bore of the distributor body. This enables a particularly simple design of the seal between the plug insert and the fluid channel and precise positioning of the plug insert in the connection point.

[0014] Particularly preferably, the locking arms have a circumferential curvature at their free, radially outer end that is more pronounced than the curvature of an inner wall of the transverse bore of the distributor body. This enables particularly gentle guidance of the locking arms over the inner surfaces, and in particular the sealing surfaces, of the transverse bore during the insertion process, since such a design prevents sharp outer edges of the locking arms from grinding against the inner surfaces of the transverse bore during insertion or when rotating the plug insert into its final position.

[0015] In a further embodiment, the locking arms have a partially cylindrical circumferential surface at their free, radially outer end. This surface, in the elastically reshaped initial state, runs parallel to the wall of the transverse bore in longitudinal section. When elastically compressed during disassembly, it forms a chamfer from the transverse bore in the disassembly direction. This enables particularly gentle guidance of the locking arms over the inner surfaces, and in particular the sealing surfaces, of the transverse bore during disassembly of the plug inserts, since this design prevents sharp locking edges of the locking arms from grinding against the inner surfaces of the transverse bore when the plug insert is pulled out.

[0016] In a further advantageous embodiment, anti-rotation means are formed on the circumference of the functional sections of the plug inserts and / or on the circumference of the connection points of the distributor body. These anti-rotation means prevent rotation of an inserted plug insert in the transverse bore and ensure correct positioning of the plug insert in the transverse bore. Advantageously, corresponding connecting means for releasably mechanically connecting the distributor body to other distributor bodies on both sides are arranged on two opposite longitudinal sides of the distributor body. In particular, the connecting means of the longitudinal sides each comprise at least two connecting elements, which are arranged spaced apart from one another on the respective longitudinal side in the longitudinal extension direction of the distributor body.Preferably, the connecting elements are designed as dovetail-shaped connecting contours on one longitudinal side or as corresponding dovetail-shaped connecting grooves on the opposite longitudinal side. Particularly preferably, the connecting contours or the corresponding connecting grooves on the longitudinal sides of the distributor body extend in a curved manner transversely to the longitudinal direction and to the fluid channel, so that they can be inserted into one another by rotating two distributor rails to be connected relative to one another. This enables a particularly simple and, at the same time, particularly stable modular expansion of the distributor system with one or more additional distributor bodies.

[0017] In a further embodiment, the connecting means of the longitudinal sides each comprise centering means arranged centrally between the connecting elements on the respective longitudinal side. The centering means are preferably designed as a pin protruding from an outer wall of the distributor body or a corresponding recess machined into the outer wall of the distributor body. In particular, the recess is arranged within an S-shaped demolding groove formed in the outer wall for a demolding tool for forming the recess. This simplifies the process of connecting two distributor bodies and prevents incorrect assembly.

[0018] In an advantageous embodiment, the connecting means of the longitudinal sides each comprise locking means for connecting to another distributor body with corresponding locking means in an end position. In particular, the connecting means of the longitudinal sides each comprise stop means for limiting a connection movement when connected to another distributor body with corresponding stop means in an end position. This enables precise positioning and stable assembly of the distributor bodies to form an extended distribution system.

[0019] In a particularly advantageous embodiment, at least one bridge plug insert is U-shaped and formed integrally with two or more plug inserts, the plug inserts being connected via a connecting web between the respective functional sections of the plug inserts, and a common internal fluid channel running through the connecting web and through the functional sections, fluidically connecting them to one another and opening into the flow openings of the respective plug inserts. Preferably, in a distributor system having multiple distributor bodies, a bridge plug insert is inserted with one of its plug inserts into each of the distributor bodies, such that it fluidically connects the fluid channels of the distributor bodies. This enables the distributor system to be expanded so that multiple distributor bodies are not only mechanically but also fluidically connected to one another.

[0020] In a further advantageous embodiment, the fluid channel is formed in cross-section based on a rectangular basic shape, wherein, in cross-section, two sides of the fluid channel into which no transverse bores of the distributor body open are divided into two partial sides extending at an angle to one another, so that the fluid channel is formed in cross-section as an irregular hexagon, in which the partial sides form the four short sides and the sides of the fluid channel into which the transverse bores open form the long sides of the irregular hexagon. In particular, the distributor body is formed as a rectangular basic body, and the fluid channel runs in the longitudinal extension direction of the distributor body.Preferably, a circular ejection opening is arranged on at least one end face of the distributor body, into which the fluid channel opens on one side. The diameter of the ejection opening is larger than the longest diagonal of the cross-section of the fluid channel. This enables particularly simple production as a one-piece injection-molded part, whereby the fluid channel and the transverse bores can be manufactured without demolding grooves on the inner surfaces.

[0021] In particular, a closure part is inserted into the demolding opening in a fluid-tight manner, wherein the closure part has a pot-like base body, wherein a base of the base body has an outer diameter that is adapted to the smallest inner diameter of the demolding opening, and a radially expanded step is arranged on the outer circumference of the peripheral wall of the base body, against which a sealing ring bears circumferentially and which has at least two locking arms on the edge that run in the direction of the base for locking onto the outer circumference of the distributor body. Preferably, at least two webs that run in the fluid channel direction are formed on the inner circumference of the demolding opening to support a closure part that can be inserted into the demolding opening. The webs support the closure part against tilting in the demolding opening and enable a reduced effective diameter of the closure part.The smaller diameter of the closure part enables a reduced outer diameter of the distributor body in the area of ​​the demoulding opening and thus relatively reduced holding forces that act on the locking arms of the closure part when inserted.

[0022] In a further embodiment, anti-rotation devices are formed on the outer circumference of the connection points to prevent rotation of an inserted plug insert in the transverse bore. Preferably, the connection points on the outside of the distributor body form a support surface or locking surface on both sides for supporting an inserted plug insert on one side or locking it on the other side. This enables secure and stable positioning of the plug inserts in the connection points of the distributor body.

[0023] In particular, the cross-bores of the connection points have continuous chamfers at the edges near the fluid channel openings and at the edges on the outside of the distributor body. This prevents sharp edges on the inner circumference of the cross-bore and prevents damage to the sealing elements of the plug inserts.

[0024] The invention further comprises an advantageous alternative embodiment of a closure part for distribution systems for fluid lines, wherein the distribution system has a distributor body with a demoulding opening and a connection point for connecting fluid lines, wherein the demoulding opening and the connection point are connected to one another via a fluid channel in the interior of the distributor body and the closure part is designed like a plug and can be held reversibly in the demoulding opening of the distributor body of the distribution system.

[0025] In particular, the demoulding opening of the distributor body is designed in alignment with the fluid channel, wherein the connection point in the distributor body is designed as a transverse bore extending transversely through the fluid channel for inserting a plug-in insert, and a plug-in insert is inserted into the transverse bore, wherein the plug-in insert has a functional section with fluidic functional means at one end and a holding section with holding means at the opposite end and in between a flow section with a flow opening and with sealing sections that fluidically seal the flow opening in the direction of the holding section and in the direction of the functional section with respect to the transverse bore, wherein between the functional section and

[0026] Flow section and between the flow section and the holding section a sealing section with a circumferential seal is arranged.

[0027] Advantageously, the closure part has an extension which, in the inserted state of the closure part, projects into the fluid channel beyond the first transverse bore of the distributor body adjacent to the demolding opening, wherein the extension has a closure part transverse bore aligned with the transverse bore of the distributor body, so that the closure part is held by means of the first plug-in insert adjacent to the first connection point, which is inserted through the closure part transverse bore and the transverse bore of the distributor body.

[0028] This allows for a simple, force- and / or form-fitting retention of the closure part, without the need for additional locking or holding elements to hold the closure part located inside the fluid channel, which would only be possible through complex processing steps, especially in injection molding processes. The closure part is locked, particularly during the assembly of a first plug-in insert, and held firmly in the sealing final position.

[0029] In addition, such closure parts according to the invention can be easily released and removed without causing any damage and can be reinserted and fastened, for example, after maintenance work on the distributor body.

[0030] A further advantage is the possibility of a shorter design of the distributor or distributor body with the closure part according to the invention, since no external locking mechanism and no correspondingly sufficient installation space are required. This also allows the closure parts to be arranged on the same side in the case of multiple coupled distributors.

[0031] In a preferred embodiment, the closure part's transverse bore has an enlarged cross-section in a partial area of ​​its inner surface. This enlarged cross-section allows sealing means, such as a sealing ring, to move laterally, particularly during movement processes such as assembly and / or disassembly, thus avoiding increased and potentially damaging loads. The enlarged cross-section preferably has a largest diameter in the center of the fluid channel. In particular, the enlarged cross-section exhibits a decreasing, in particular continuously tapering, diameter with increasing distance from the center of the fluid channel. In particular, this allows for gentle guidance of the sealing sections, which usually have sealing rings.This allows a sealing ring to be brought to tapered and, in particular, sealing end positions with increased pressure loads in a sliding manner both during insertion and removal of the plug insert without being damaged.

[0032] Otherwise, damage may occur, especially due to unrounded edges on the distributor body or other injection-molded parts. Adequately rounding edges is often difficult, especially in the interior areas of a complex injection-molded component. In these cases, gently applying the sealant to less rounded edges is crucial for damage-free assembly and / or disassembly of the components.

[0033] In particular, a window-like cross-sectional enlargement is present in an azimuthal angular range of the inner circumferential surface of the closure part's transverse bore. This window-like cross-sectional enlargement provides the sealing section with more space and circumference when inserting or removing the plug insert, thus avoiding constriction during the corresponding movements and preventing wear or damage.

[0034] Specifically, the closure part has a cross-sectional enlargement in an azimuthal angle range that varies with the depth. This allows for a curved border around the window-like cross-sectional enlargement, so that abrupt changes in the diameter distribution of the closure part's transverse bore are avoided during insertion or removal of the plug insert. Instead, smooth transitions are created with respect to the diameter and the associated pressure, particularly on sealing elements, which can prevent wear or damage to the sealing sections during insertion or removal of the plug insert.

[0035] In another preferred embodiment, the window-like cross-sectional enlargement has a partially arcuate, helical, or screw-shaped border. A curved border or a curved edge of the window-like cross-sectional enlargement can assume almost any continuous curve. Preference is given to curves which partially resemble a 90° arc, in particular are sinusoidal or parabolic, and / or can be represented by a function which can essentially be described by a polynomial, very particularly by a straight polynomial. In particular, in addition to a screw-like or helical shape, the window-like cross-sectional enlargement can also assume quadratic, exponential, or other continuous curve shapes with respect to the border. Curve shapes which initially cause a smaller taper during insertion or removal processes are advantageous.This in turn allows for gentle loading of the sealing section.

[0036] The cross-sectional enlargement is preferably present in the upper region of the closure part's transverse bore and in the lower region of the closure part's transverse bore. This ensures that the lower sealing section, which is inserted deeper into the transverse bore, is gently inserted into or guided past both the upper and lower taper of the transverse bore and the closure part's transverse bore, in particular without the lower sealing section being damaged on a potentially unrounded edge of the distributor body. The diameter enlargement in the upper region of the closure part's transverse bore is particularly advantageous during the insertion process. The cross-sectional enlargement in the lower region of the closure part's transverse bore is particularly advantageous during the removal process. This creates smooth and therefore particularly gentle transitions with regard to the pressure load on the sealing section.

[0037] In a further preferred embodiment, the closure part's transverse bore has alternating demolding of the inner chamfer. Alternating demolding of the inner chamfer represents an easily implementable possibility for enlarging the cross-section. This makes it possible, in particular, to simplify injection molding without complex post-processing steps. A corresponding injection molding tool can then be created using a molding component inserted from above and below. Undercuts, which are difficult to create, are thus avoided, and the component and its molding tool can be manufactured more economically. In addition, this makes it possible to support the plug insert close to the axis in its final position - in particular also in a sealing and / or form-fitting manner - and / or to achieve a form-fitting connection with the transverse bore, at least in a partial area.Ideally, this can be used to withstand permanent pulsation due to low play and thus reduce wear.

[0038] Typically, the closure part's cross-bore is open laterally toward the fluid channel. This ensures that the fluid channel remains permeable to the fluid, such as a liquid or gas. However, it is also conceivable to install a check valve or filter on the closure part.

[0039] In particular, the closure part has at least one retaining means, preferably two or more retaining arms, at the free end of the extension. The retaining arms advantageously engage in a retaining groove arranged on the inner circumference of the fluid channel. The locking arms on the outer edge can then preferably be omitted. Particularly advantageously, the closure part forms an end-face outer wall of the distributor body and, in this respect, also comprises at least one of the fastening means.

[0078] In the various figures of the drawing, identical parts are always provided with the same reference symbols.

[0079] With regard to the following description, it is claimed that the invention is not limited to the exemplary embodiments and thereby not to all or several features of the described combinations of features; rather, each individual partial feature of the / each exemplary embodiment is also important for the subject matter of the invention, independently of all other partial features described in connection therewith, both on its own and in combination with any features of another exemplary embodiment. Figure 1 shows a three-dimensional view of an exemplary embodiment of a distribution system 1 according to the invention, with two distribution bodies 10 according to the invention and four plug inserts 30 according to the invention, each inserted into connection points 11 of the distribution bodies 10. In the illustrated embodiment of the distribution system 1, two distribution bodies 10 are mechanically detachably connected to one another lengthwise, next to one another.A closure part 50 according to the invention is inserted into a demolding opening 13 formed on the end face of each of the distributor bodies 10. The number of connection points 11 of a distributor body 10 is, in principle, arbitrary, so that distributor bodies 10 with only two or three or even more than four connection points 11 are also conceivable.

[0080] Figures 2a, 2b, 2c, 2d, 2e, 2f, and 2g show different views of an embodiment of a distributor body 10 according to the invention. The distributor body 10 is designed, in particular, as a rectangular base body and preferably as a one-piece plastic injection-molded part. As can be seen in particular in Figure 2f, a fluid channel 15 runs within the distributor body 10 in the longitudinal direction of extension, fluidically connecting all connection points 11. The fluid channel 15 opens at the front into the demolding opening 13 (not shown in Figure 2f). For this purpose, the connection points 11 are each designed as a transverse bore 17 running transversely through the fluid channel 15 for inserting the plug-in inserts 30. Preferably, the connection points 11 are designed symmetrically such that a plug insert 30 can be inserted from both one side of the transverse bore 17 and the other side of the transverse bore 17.In particular, the distributor body has a plurality of fastening means 14 for attaching the distributor system 1 to another object. The fastening means 14 comprise, in particular, a plurality of screw holes arranged on both sides of the distributor body 10.

[0081] The transverse bores 17 of the connection points 11 preferably have circumferential chamfers 18 at the edges in the region of the openings with the fluid channel 15 and at the edges on the outside of the distributor body 10. In particular, the transverse bores 17 form cylindrical sealing surfaces 19 in the region of the outer wall of the distributor body 10.

[0082] Advantageously, the connection points 11 on the outside of the distributor body 10 form a support surface 20 on both sides for supporting an inserted plug-in insert 30 on one side or for locking it on the other side.

[0083] As can be seen particularly in Figure 2g, the fluid channel 15 is preferably formed in cross-section based on a rectangular basic shape and is formed in particular by an injection molding tool (not shown) that can be inserted laterally through the demolding opening 13, in particular by means of a collapsible core. The fluid channel 15 is closed in particular on the opposite end face of the demolding opening 13 by the wall of the distributor body 10.In order to improve demoulding during the manufacturing process, the rectangular basic shape is preferably modified such that, in cross section, two sides of the fluid channel 15, into which no transverse bores 17 of the distributor body 10 open, are divided into two partial sides 21a, 21b running at an angle to one another, so that the fluid channel is designed in cross section as an irregular hexagon, in which the partial sides 21a, 21b form the four short sides and the sides of the fluid channel 15, into which the transverse bores 17 open, form the long sides of the irregular hexagon.

[0084] The demolding opening 13 is advantageously circular and arranged at least on one end face of the distributor body 10. The diameter of the demolding opening 13 is in particular larger than the longest diagonal of the cross section of the fluid channel 15. Particularly advantageously, at least two webs 22 extending in the direction of the fluid channel 15 are formed on the inner circumference of the demolding opening 13 for supporting a closure part 50 insertable into the demolding opening 13. The webs 22 are in particular distributed over the inner circumference of the demolding opening 13 and, viewed in cross-section, are preferably arranged distributed in the region of the sides of the hexagon, so that no webs 22 are arranged in the region of the corners between the long sides and the short sides of the hexagon.

[0085] In particular, anti-rotation means are formed on the outer circumference of the connection points 11 in the region of the openings, which prevent rotation of an inserted plug-in insert 30 in the transverse bores 17. The anti-rotation means are formed in particular as at least one projection 23, preferably two opposing projections 23, on the outer circumference of the openings of the transverse bores 17, which interact with corresponding anti-rotation means of the plug-in inserts 30. In principle, other anti-rotation means are also conceivable, such as interlocking hexagonal geometries.

[0086] As can be seen in particular in Figures 2a, 2b, 2c, 2d and 2e, in an advantageous embodiment, mutually corresponding connecting means for detachably mechanically connecting the distributor body 10 to other distributor bodies 10 on both sides are arranged on two opposite longitudinal sides of the distributor body 10. The connecting means of the longitudinal sides in particular each comprise at least two connecting elements, which are arranged spaced from one another on the respective longitudinal side in the longitudinal extension direction of the distributor body 10. Preferably, the connecting elements are designed as dovetail-shaped connecting contours 24 on one longitudinal side and as corresponding dovetail-shaped connecting grooves 25 on the opposite longitudinal side.To connect two distributor bodies 10, the connecting contours 24 of one distributor body 10 are pushed into the connecting grooves 25 of the other distributor body 10. Advantageously, the connecting contours 24 or the corresponding connecting grooves 25 on the long sides of the distributor body 10 extend in a curved manner transversely to the longitudinal direction and to the fluid channel 15, so that they can be inserted into one another by rotating two distributor bodies 10 to be connected relative to one another. Furthermore, the connecting means of the long sides can advantageously each comprise centering means arranged centrally between the connecting elements on the respective long side. The centering means are designed in particular as a pin 26 protruding from an outer wall of the distributor body or as a recess 27 corresponding to the pin 26 and machined into the outer wall of the distributor body on the opposite long side.The recess 27 is arranged in particular within an S-shaped demolding groove 28 formed in the outer wall for a demolding tool for forming the recess 27.

[0087] Advantageously, the connecting means of the longitudinal sides each comprise locking means 29 for locking to another distributor body 10 with corresponding locking means in an end position. The locking means 29 are designed, in particular, as a locking arm or a locking groove formed in the outer wall of the distributor body 10. In particular, the connecting means of the longitudinal sides each comprise stop means for limiting a connection movement when connected to another distributor body with corresponding stop means in an end position.

[0088] Figures 3a, 3b, and 3c show a process by which two distributor bodies 10 can be pushed into one another in a preferred embodiment. First, the distributor bodies 10 are rotated approximately 120° to 160° relative to one another, with one long side with the pin 26 of one distributor body 10 opposite the long side with the recess 27 of the other distributor body 10. The pin 26 is then moved into the recess 27 until the pin 26 can enter the recess 27. Subsequently, the distributor bodies 10 are brought into a parallel position by a relative rotation to one another via the shortest path, with the connecting contours 24 of one distributor body 10 engaging the connecting grooves 10 of the other distributor body 10. In the parallel end position, the mutual locking means 29 rust into one another, so that the end position is fixed by rust.Figures 4a, 4b, and 4c illustrate an advantageous embodiment of a plug-in insert according to the invention. The plug-in insert 30 has a functional section 33 with fluidic functional means at one end and a holding section 37 with holding means at the opposite end. Between them, there is a flow section 35 with a flow opening 43 and sealing sections 39 that fluidically seal the flow opening 43 in the direction of the holding section 37 and in the direction of the functional section 33 with respect to the transverse bore 17. In particular, O-ring seals are arranged in the sealing sections 39 as sealing means 40.

[0089] The functional elements in the functional section 33 of the plug-in insert 30 can be designed as a plug-in mandrel, as shown. Other possible designs include, for example, a push-to-connect coupling, plug-in coupling, closure, or test valve. However, other fluidic functional elements are also conceivable.

[0090] The holding means arranged in the holding section 37 of the plug inserts can be pushed through the transverse bore 17 of a distributor body 10, and the flow section 35 can be inserted into the transverse bore 17 of the distributor body, wherein, in particular, the longitudinal axis of the flow opening 43, in the inserted state, runs axially parallel to the longitudinal axis of the fluid channel 15. In particular, a circumferential extension 42 is formed at the transition from the functional section 33 to the adjacent sealing section 38, which limits the insertion depth of the plug insert 30 in the transverse bore 17 of the distributor body 10.

[0091] The holding section preferably has at least two radially inwardly elastically deformable locking arms 41 as holding means, which are designed such that they are radially compressed when inserted into the transverse bore 17 of a distributor body 10 and, when maximally inserted in the distributor body 10, extend through the transverse bore 17 and expand radially elastically outside the transverse bore 17 and become fused to the outer wall of the distributor body 10. In an advantageous embodiment, the locking arms 41 have a circumferential curvature at their free, radially outer end which is more curved than the curvature of the wall of the transverse bore 17 of the distributor body 10 into which the plug insert 30 can be inserted. This is illustrated in particular in Figure 4f, which shows an enlargement of a quarter section of the cross section of a partially inserted plug insert 30 in a distributor body 10.In this insertion position, the locking arms 41 rest only with their apex 47 of the circumferential curvature on the sealing surface 19 of the transverse bore 17 of the distributor body 10 and form a gap 49 for the remainder of the circumferential edge surfaces of the locking arms 41 between the edge surfaces of the locking arms 41 and the sealing surface 19 of the transverse bore 17.

[0092] In particular, the locking arms 41 have a partially cylindrical circumferential surface 45 at their free, radially outer end, which, in the elastically reshaped initial state of the locking arms 41, runs in longitudinal section parallel to the wall of the transverse bore 17 of the distributor body 10, into which the plug insert 30 can be inserted, and in the elastically pressed-in state during disassembly from the transverse bore 17, forms a chamfer due to the inclined position of the circumferential surface 45 in the disassembly direction (see in particular Figure 4e). Anti-rotation means are preferably formed on the circumference of the functional sections 33 of the plug inserts 30, which prevent rotation of an inserted plug insert in the transverse bore 17 of the distributor body 10 and ensure correct positioning of the plug insert 30 in the transverse bore 17 of the distributor body 10. These interact in particular with anti-rotation means, in particular the projection 23, of the connection points 11.

[0093] To disassemble the plug inserts 30 according to the invention, it is advantageous to use a disassembly sleeve 60 (see Figure 4g and Figure 4h) which can be inserted into the holding section 37 of the plug inserts 30 into a front-side receiving opening 44. For this purpose, the holding means of the holding section 37 advantageously have inwardly bent U-shaped hook sections 46 at their free ends, which on their radially inner legs on the radially outer side form in particular a retraction surface 48 which, in the elastically reshaped initial state of the holding means, runs obliquely to the insertion direction of the disassembly sleeve 60.

[0094] By inserting the disassembly sleeve 60 by means of the actuating section 61, the latter strikes the retraction surface 48 with its front end face of an insertion section 63 and, due to the axial insertion force, pulls the holding means radially inward into the elastically deformed state, so that the holding means release the plug-in insert 30 and the latter can be pulled out of the transverse bore 17, wherein the holding means are held in the elastically deformed state over the entire disassembly path and springing back into the initial state, in particular within the fluid channel 15, is avoided.

[0095] In a particularly advantageous embodiment, a bridge plug insert (not shown) is U-shaped and formed as one piece from two or more plug inserts 30, wherein the plug inserts 30 are connected via a connecting web between the respective functional sections 33 of the plug inserts 30, and a common internal fluid channel runs through the connecting web and through the functional sections 33 and fluidically connects them to one another and opens into the flow openings 43 of the respective plug inserts 30.

[0096] In a distribution system 1 with several distribution bodies 10, the bridge plug insert can be inserted with one of its plug inserts 30 into a respective distributor body 10, so that the fluid channels 15 of the distributor bodies 10 are fluidically connected to one another and the distribution system 1 can thus be expanded by additional connection points 11.

[0097] Figures 5a and 5b show an embodiment of a closure part 50 according to the invention for fluid-tightly closing the demolding opening 13. The closure part 50 has, in particular, a pot-shaped base body 51, the outer diameter of which is adapted to the smallest inner diameter of the demolding opening 13 of the distributor body 10. In particular, the base body 51 has a base 53, in the region of which the outer diameter is smaller than the outer diameter of the remaining base body 51, so that a circumferential chamfer is formed in the region of the base 53 in the insertion direction.

[0098] Advantageously, the closure part 50 has a radially expanded step 55 on the outer circumference of the peripheral wall of the base body 51, against which a sealing ring 57 rests circumferentially. Advantageously, the closure part 50 has at least two locking arms 59 on the outer edge, extending in the direction of the base 53 along the peripheral wall of the base body 51, for locking onto the outer circumference of the distributor body 10.

[0099] Figures 6a, 6b, 6c, 6d, 6e, and 6f show an embodiment of a distributor system 1 according to the invention, consisting of two assembled distributor bodies 10, whose demolding openings 13 are each closed with a closure part 50. Four plug-in inserts 30 are inserted into each of the two distributor bodies 10.

[0100] In an advantageous embodiment according to Figures 7a, 7b, 7c, 7d, the closure part 50b is designed like a plug and is reversibly held in the demolding opening 13 of the distributor body 10 of the distributor system. Advantageously, the closure part 50b has an extension 52 which, when the closure part 50b is inserted, extends into the fluid channel 15 at least beyond the first transverse bore 17 of the distributor body 10 adjacent to the demolding opening 13. The outer contour of the extension 52 is particularly adapted to the inner contour of the fluid channel 15 and is advantageously hexagonal. In particular, the extension 52 has a closure part transverse bore 54 aligned with the transverse bore 17 of the distributor body 10, so that the closure part 50b is held by means of the first plug-in insert 30 adjacent to the demolding opening 13, which is inserted through the closure part transverse bore 54 and the transverse bore 17 of the distributor body 10.The closure part's transverse bore 54 is open laterally, at least in the direction of the fluid channel. In particular, the closure part 50b has at least one retaining means, preferably two retaining arms 58, at the free end of the extension 52. The retaining arms 58 advantageously engage in a retaining groove arranged on the inner circumference of the fluid channel 15. The retaining arms 58 are particularly designed as force-locking locking arms that can be released without damage. The locking arms 59 on the outer edge can then preferably be omitted. Particularly advantageously, the closure part 50b forms an end-face outer wall of the distributor body 10 and, in this respect, also comprises at least one of the fastening means 14.

[0101] In a further advantageous embodiment of the closure part 50b according to Figures 7e, 7f, 7g, 7h, 7i, 7j, the closure part transverse bore 54 has a cross-sectional enlargement 64 in a partial area of ​​the inner surface.

[0102] Fig. 7e first shows a partial enlargement (left) of the closure part according to Fig. 7a-c from a further three-dimensional view (right), which differs in perspective from Fig. 7a. In the enlargement of the circular, enlarged section, a cross-sectional enlargement 64 is visible in a partial area of ​​the circumferential surface in the form of a depression. The partial area with a depression can also be described as an azimuthal angular range that varies with depth. Fig. 7e shows a curved border of the window-like cross-sectional enlargement 64, so that during insertion or removal processes of the plug insert, abrupt changes in the diameter distribution of the closure part transverse bore 54 are avoided and smooth, continuous and, in particular with regard to the first derivative, continuous transitions are generated with regard to the diameter and the associated pressure on the sealant.

[0103] Fig. 7e also shows that the cross-sectional enlargement 64 is window-like and has a partially curved, helical, or screw-shaped border. More specifically, the cross-sectional enlargement 64 can be described as a reciprocal demolding or deepening of the inner bevel. This is particularly reciprocal, since the area of ​​the cross-sectional enlargement 64 represents a right and a left angled area, which are designed for gentle insertion and removal of a connector with its sealing means, respectively, while allowing the sealing means space to move freely or to continuously approach the final position.

[0104] Figures 7f to 7j show sections through cutting planes of the closure part 50b, illustrating the shape of the cross-sectional enlargement 64. This is designed such that molding tools can be inserted into the closure part's transverse bore 54 from both above and below, and can easily create the described advantageous cross-sectional enlargement 64 without undercuts.

[0105] Fig. 8 shows a comparison of two distribution systems 1, which are arranged one below the other as a partial section of two distribution systems 1 on the same scale, each with a different closure cap 50, 50b. The upper distribution system 1 comprises the closure cap 50 according to Figures 1 to 6f. The lower distribution system 1 comprises a closure cap 50b according to Figures 7a to 7j. It can be seen in particular from Fig. 8 that the embodiment with the closure cap 50b according to Figures 7a to 7j enables a reduction in installation space by shortening V.

[0106] Fig. 9 shows a distribution system 1 with three connected distributor bodies 10, each distributor body 10 being closed at the end with a closure cap 50b according to Figures 7a to 7j. With a double-sided arrangement of the closure caps, in which the distributor bodies 10 are connected to one another in such a way that at least one closure cap 50b is arranged on each side of the distribution system 1, the advantageous design of the closure cap 50b even enables a double reduction in installation space of 2 x V. In addition, such a design of the closure cap 50b also enables the closure cap 50b to be designed so that its width is flush with the distributor body 10, so that two distributor bodies 10 arranged next to one another can also be connected to one another in the same direction, ie with the demolding opening 13 on the same side of the distribution system 1.The invention is not limited to the illustrated and described embodiments, but also encompasses all equivalent embodiments within the meaning of the invention. It is expressly emphasized that the embodiments are not limited to all features in combination; rather, each individual partial feature can also have an inventive significance in itself, independently of all other partial features. Furthermore, the invention is not yet limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed as a whole. This means that, in principle, practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.
