Description

Field of the invention

[0001] The present invention relates to a receiving system configured to receive a contact element carrier and at least one contact element received in the contact element carrier to form part of a built-in connector. Background of the invention

[0002] Flush-mounted connectors with a multi-part design are known from the prior art. Here, the contact pins, often also referred to as pins or sheets, are inserted into a contact carrier. This contact carrier, in addition to receiving and aligning the contact pins, also has the function, among other things, of providing the interior space into which the cable connector is inserted to establish contact with the contact pins. This interior space can also have elements for locking the cable connector. Furthermore, in specific embodiments of such flush-mounted connectors, the contact carrier provides a flange designed to support the contact carrier and thus also the flush-mounted connector on a region of the flush-mounted panel surrounding a recess in the panel.The flange can also have mounting holes through which, for example, screws for screwing the built-in connector to the mounting plate can be passed.

[0003] To assemble the panel connector, the contact carrier is inserted into a receiving system. In the prior art, this receiving system is typically designed as a one-piece panel connector housing, with parts of the contact pins being pushed out of the panel connector housing through specially provided openings. These parts of the contact pins protruding from the housing are then each connected, for example, via terminals specifically designed for this purpose, to strands of a cable, such as a power cable. This cable provides the signal intended for transmission via the plug-in connection between the panel connector and the cable connector, such as a power supply signal.

[0004] In prior-art panel-mount connectors, the entire receptacle system or the entire panel-mount connector housing is made of a hard, inelastic material (e.g., a harder thermoplastic). This harder housing does not fit as tightly against the contact pins pushed out through the openings in the housing. Consequently, these interference fits between the prior-art panel-mount connector housing and the corresponding contact pins are leaky / permeable to dust, water, humidity, and / or gases, especially air.

[0005] Such a leak between the housing and the contact pin is particularly problematic for outdoor applications of the panel connector (e.g., loudspeaker boxes at open-air festivals). Rainfall, for example, can occur at any time, and water can penetrate the panel connector if no cable connector is plugged in and the sealing cap intended for temporarily closing and sealing the interior of the panel connector has not been installed. The water that has penetrated can then run down to the interference fit between the panel connector housing and the contact pin and collect there.Since this press fit, as already mentioned, is not water-tight due to the harder housing material, especially when it comes to water, there is a risk with state-of-the-art built-in connectors that the moisture will penetrate further into the device and thus lead to a short circuit, which can damage the device and, in the worst case, injure bystanders.

[0006] State-of-the-art panel-mounted connectors solve the described problem by additionally sealing the contact points between the contact pins and the housing using sealants such as adhesives, sealing pastes, sealing rings (e.g., O-rings), etc. However, this reveals a disadvantage of panel-mounted connector housings or panel-mounted connectors of the state-of-the-art, as these additional components / sealing materials result in additional costs (e.g., material procurement costs, additional machines / employees) and, for example, additional labor, due to additional work steps. For example, before assembling the panel-mounted connector by plugging together the receiving system or panel-mounted connector housing, contact carrier, and contact pins, the corresponding sealing rings must be inserted / attached, or the still-liquid adhesive must be applied. Object of the invention

[0007] It is therefore an object of the invention to provide a receiving system and a built-in connector which overcome the disadvantages of the prior art, in particular in light of the strict requirements with regard to safety and the worldwide established installation dimensions.

[0008] A further object is to provide a receptacle system and a built-in connector in which the creation of a seal against dust, water, humidity and / or gases, in particular air, is simplified, thereby enabling outdoor use, reducing the risk of short circuits and / or meeting certain standards without additional work.

[0009] These objects are achieved by implementing at least some of the characterizing features of the independent patent claims. Features that further develop the invention in an alternative or advantageous manner can be found in some of the remaining features of the independent patent claims and the dependent patent claims. Summary of the invention

[0010] The invention relates to a receiving system configured to receive a contact element carrier and at least one contact element received in the contact element carrier to form part of a built-in connector, wherein the receiving system has a housing pot, configured such that the contact element carrier can be at least partially inserted into the housing pot through an insertion opening on a plug-in end (or also: on a side / end provided for the installation of the receiving system or the built-in connector on a mounting plate as the mounting plate side) of the housing pot, wherein a flange-like projection is arranged on the insertion opening of the housing pot, and the receiving system is intended to be placed and fastened to a rear side of a mounting plate with the flange-like projection of the housing pot, where the housing pot is made of a material with a Shore A hardness in the range of 60 to 100 and the receiving system further comprises a support ring which is made of a harder material than the housing pot, wherein the housing pot can be passed through the support ring to such an extent that the housing pot abuts the support ring with the flange-like projection, so that in a state installed on the mounting plate, the flange-like projection is arranged between the mounting plate and the support ring, and the support ring has a bore, in particular a blind bore, configured so that the support ring is fastened to the rear of the mounting plate by means of a fastening means which passes from a front side of the mounting plate through the mounting plate and engages in the bore.

[0011] The inventive design of the receiving system / built-in connector with a housing pot made of a softer, more elastic material than in the case of receiving systems / built-in connectors of the prior art has the advantage that the housing pot and the opening of the housing base can be manufactured with such dimensions that, on the one hand, the housing pot fits tightly against the contact element carrier when it is pushed in, which is made of a harder plastic (e.g. a harder thermoplastic), and, on the other hand, the opening of the housing base fits snugly against the contact element that has been passed through.In other words, the opening in the housing base has a slightly smaller surface area than the cross-sectional area of ​​the part of the contact element that is pushed out of the housing cup through the opening in the housing base, so that the opening in the housing base expands when the contact element is pushed out, for which a certain force must be applied. The surface extending into the opening in the housing base then presses on the contact element with a force that counteracts this expansion, forming a so-called press fit between the opening and the contact element. Because the housing cup of the receptacle system / flush-mounted connector according to the invention is made of a softer, more elastic material (e.g., comparable to rubber), it can expand more easily and, at the same time, conform better to the contact element.In this way, press fits between the soft, elastic housing pot and the harder, more inelastic contact element are impermeable to dust, water, humidity and / or gases, in particular air, whereby the entire built-in connector, when installed, is sealed against dust, water, humidity and / or gases, in particular air, even if, for example, during rainfall, the sealing cap was forgotten to be put over the insertion opening of the built-in connector and water could therefore get into the built-in connector.

[0012] Due to the watertight and airtight press fit between the soft, elastic housing pot and the at least one contact element, the built-in connector having the receiving system according to the invention is able to meet the IP65 and IP67 standards, even when the sealing cap is not in place or the cable connector is plugged in, without the need for additional components / sealing materials (such as a liquid sealant that hardens after application). Consequently, the receiving system / built-in connector according to the invention can save additional costs (e.g. material procurement costs, additional machines / employees) and additional labor, for example through additional work steps, on the one hand. These additional costs / work steps are therefore not incurred with the receiving system / built-in connector according to the invention, since the watertight and airtightBecause of the airtight press fits, no further sealing is necessary, which is why the disadvantages of the state of the art have been overcome.

[0013] In an exemplary embodiment of the receiving system according to the invention, the housing pot is made of a material with a Shore A hardness in the range of 65 to 95, in particular in the range of 75 to 95. When selecting the hardness of the material, or the composition of the components that provide the hardness of the material, the aspects of tightness and processability must be taken into account. If the material is selected to be too hard, then although processability is simplified, in particular by injection molding, the sealing effect is reduced. If the material is too soft, the sealing effect is very good, but fine structures such as sealing lips are difficult to manufacture (e.g. undercuts are hardly possible in the injection molding process). In particular, with a Shore A hardness in the range of 65 to 95, both tightness and processability of the housing pot are guaranteed.

[0014] Because the support ring in the inventive receiving system is made of a harder material, the support ring does not warp when tightening the fasteners or when assembling the built-in connector, which is why the support ring can exert an increased and also permanent supporting effect on the housing pot.

[0015] Due to this optimized and permanent support effect of the support ring, the housing pot of the inventive receiving system can be made of a softer material than the prior art, without the soft, flexible housing pot during assembly of the built-in connector according to the invention, e.g. when inserting the contact element carrier and / or pushing the contact elements out of the openings in the housing base, when passing through the fastening means or when tightening the corresponding fastening means, which then exert a certain contact pressure on the housing pot, are distorted / deformed by the rotational or lever forces exerted by a cable connector plugged into the contact element carrier, by the tensile forces acting on the housing pot, triggered by strands and / or terminals that are fastened to the passed-through contact elements, and / or by the force of gravity acting on the housing pot, and contact areas between the components, in particular between the insides of the openings in the housing base and the respective passed-through contact elements, become leaky with regard to dust, water, humidity and / or gases, in particular air.

[0016] In an exemplary embodiment of the recording system according to the invention, the material of the support ring has a Shore D hardness in the range of 60 to 100, and / or a material of the contact element carrier has a Shore D hardness in the range of 60 to 100.

[0017] Although one of the main functions of the contact element carrier is to accommodate the contact elements, in particular three, (also called pins or sheets), the term contact element carrier does not just refer to a pure contact element holder. The contact element carrier also has the task of providing the socket for receiving the cable plug as well as elements for locking the cable plug in this socket. Furthermore, in special embodiments the contact element carrier provides the flange, through whose recesses fastening means (e.g. screws for screwing on) of the contact element carrier to the mounting plate (e.g. a loudspeaker box) are led. The contact element carrier therefore also serves as a type of skeleton or support structure which accommodates or supports the other parts of the panel connector.is surrounded by it and, as a supporting and shaping structure, for example, spans the interior of the built-in connector intended to accommodate and lock the cable connector.

[0018] If the contact element carrier is made of a harder material than the housing pot in addition to the support ring, the housing pot is additionally supported from the inside, which prevents a previously described deformation of the housing pot (associated with a leak in the built-in connector) and generally stabilizes the receiving system according to the invention or the built-in connector according to the invention.Furthermore, the hard insertion-side end and the hard flange of the contact element carrier, in particular around the recesses of the flange of the contact element carrier, form a hard stop on the back of the mounting plate when the fastening means are tightened, wherein this hard stop prevents the flange-like projection, which is also made of the soft material and is also attached to the back of the mounting plate, from being compressed to such an extent that an undesirable deformation of the flange-like projection occurs (e.g. a lateral swelling out of the flange-like projection between the back of the mounting plate and the mounting flange of the support ring), in particular at the recesses of the flange-like projection.Such an undesirable deformation of the flange-like projection, in particular at the recesses of the flange-like projection, could in turn lead to leaks within the built-in connector according to the invention.

[0019] By designing the support ring and contact element carrier from a harder, less flexible material than the housing shell, the handling of the mounting system or the built-in connector is made easier. This allows the installer to tighten the fasteners (e.g., screws or bolts) firmly until they feel a stop when mounting the mounting system or the built-in connector to the mounting plate of a device, without the previously described protrusion of the flange-like projection occurring. Furthermore, the likelihood of damage to the built-in connector during assembly is reduced due to the harder, more stable components.

[0020] In a further embodiment of the receiving system according to the invention, the material of the housing pot, the material of the support ring, and / or the material of the contact element carrier consists at least predominantly of a plastic, in particular wherein the plastic is a thermoplastic, in particular one of the following thermoplastics: Polypropylene, polyethylene, polyurethane (e.g. "thermoplastic polyurethane"), or other thermoplastic elastomers (e.g. styrene-ethylene-butylene-styrene (SEBS)), or polystyrene.

[0021] For example, the housing shell material can be made of at least 60%, particularly at least 80%, plastic, with additives such as plasticizers or flame retardants mixed into the plastic. Especially for powerCON type panel connectors (powerCON chassis sockets) from Neutrik AG in Liechtenstein, also known as the Neutrik Group, it is of great importance that the housing shell material is flame-retardant, which can be achieved, for example, by adding flame retardants to the housing shell material.

[0022] In a further embodiment of the receiving system according to the invention, the housing pot, the support ring and / or the contact element carrier are manufactured by means of injection molding processes, 3D printing processes, pressing processes or vulcanization processes.

[0023] The use of a thermoplastic (or a thermoplastic elastomer) as the main component for the soft material has the advantage, among other things, that the housing pot can be manufactured using injection molding, 3D printing, pressing, or vulcanization, and that the housing has an insulating effect against electrical current.

[0024] Because the housing pot, contact element carrier, and / or support ring are manufactured as a single piece, there are no contact points, gaps, transitions, etc. within the respective component where leaks could occur or that require additional sealing with an O-ring or adhesive. This also eliminates the need for sealing materials and fewer work steps compared to the state of the art. Furthermore, several functions are combined within the respective component, which in turn enables simplified handling (or simplified assembly, since fewer parts need to be plugged together).

[0025] The injection molding process enables simple production of the respective components of the inventive receptacle system / flush-mounted connector, and in particular simple production of the housing pot. For production by injection molding, it is necessary that the material used can first be melted and then injected into the corresponding mold. Furthermore, the material must be able to solidify in the corresponding mold upon cooling and retain this solidified shape until reheated. It is therefore particularly advantageous for the materials of the inventive receptacle system / flush-mounted connector to comprise a thermoplastic material or to consist predominantly of this thermoplastic material (orthermoplastic elastomer) (additives such as plasticizers or flame retardants are often added), since many thermoplastics exhibit the properties described above and are therefore suitable for injection molding. Furthermore, some thermoplastics, particularly amorphous thermoplastics such as low-density polyethylene (LD-PE), atactic polypropylene (PP-at), or atactic polystyrene (PS-at), have a Shore hardness that is quite close to the Shore hardness of the soft material of the housing pot.

[0026] Since the contact element carrier and the support ring are intended to form the support structure / skeleton of the flush-type connector, it is particularly advantageous if the contact element carrier and the support ring are made of a harder material than the housing pot. Since, in an advantageous embodiment, the contact element carrier and the support ring are manufactured just like the housing pot using injection molding, 3D printing, pressing, or vulcanization, it is particularly advantageous if the material of the contact element carrier and the support ring comprises a thermoplastic, in particular predominantly consists of this thermoplastic. Semi-crystalline thermoplastics, such as isotactic PP, isotactic PS, or high-density polyethylene (HD-PE), would be suitable for this purpose.

[0027] The advantages of manufacturing the respective components of the inventive receptacle system / flush-mounted connector using injection molding are that, on the one hand, the injection molding process allows for high-precision manufacturing and, on the other hand, that various components (e.g., plastic and flame retardant) can be mixed together in different proportions according to a "recipe-like" formula. Subsequently, it can be tested whether the final product exhibits the desired material properties with the used formula, and the formula can be adjusted if necessary.

[0028] A further advantage of an embodiment of the inventive receptacle system / flush-mounted connector compared to the prior art is that the housing pot exhibits the aforementioned Shore A hardness despite the addition of a flame retardant. Manufacturing such a flame-retardant V0 material in this Shore A hardness range is a major challenge, as materials previously treated with such flame retardant become very hard and brittle, thus losing their sealing effect. Flame retardancy is particularly important for powerCON-type flush-mounted connectors, as these connectors must comply with the UL 94 standard (i.e., the material and connector must be V0 certified according to UL94 at 1 mm). Due to the standards and requirements of these standards, it is advantageous to add flame retardant (a certain proportion of a flame-retardant additive) to this material.The protection category can be determined by the percentage of flame-retardant additive added to the overall mixture.

[0029] Furthermore, in another embodiment, the material of the housing pot can also be UV-stabilized (according to UN standard UL50E, and thus requires a UL f1 certificate). For this purpose, UV stabilizers of 10-15 wt% (by weight), 10-15 mol% (by mole), or 10-15 vol% (by volume) are added to the material. Due to the UV stabilization, the inventive receptacle system / panel connector can be used outdoors. An example of this is the "True Outdoor Protection" (TOP) product series from Neutrik AG of Liechtenstein, also known as the Neutrik Group.

[0030] The soft material of the housing pot of the receiving system according to the invention is furthermore designed in such a way that so-called undercuts can also be realized during the production of the housing by means of injection molding, which enables, for example, the design of the sealing lip or the wall-like elevation.

[0031] In a further embodiment of the receiving system according to the invention, the housing pot further comprises: a housing base at a rear end of the housing pot opposite the insertion end, and a housing shell extending from the insertion opening to the housing base, wherein a radial extension (in other words: the diameter or dimension) of the support ring and a radial extension (in other words: the diameter or dimension) of the housing shell are such are coordinated with one another, so that when the housing pot is passed through the support ring, the housing shell rests against an inner side of the support ring and is supported thereby, in particular wherein the support ring has an extension which runs axially in a direction in which the housing pot is passed through the support ring (also corresponds to: the direction in which the central axis of the housing pot runs from the plug-in end to the housing base, the direction of insertion of the contact element carrier into the housing pot, and the direction in which the cable connector is inserted into the contact element carrier (or the direction in which the cable connector is inserted into the built-in connector)), so that at least 50% of the housing shell can be supported by the support ring.

[0032] In a further embodiment of the receiving system according to the invention, the housing base has: an opening provided so that, when the contact element carrier is at least partially inserted into the housing pot together with the contact element to form the part of the built-in connector through the insertion opening, at least part of the contact element is passed through the opening, so that at least the part of the contact element passed through the opening in the housing base is present on an outer side of the housing base, and / or an element surrounding the opening in the housing base, which engages with a corresponding counter-element of the contact element carrier, wherein the contact element carrier can be fixed in the housing pot by the engagement of the element and the counter-element, in particular where a contact area formed between the at least partially passed through contact element and an inner side of the opening of the housing base, and / or a contact area formed between the element and the counter element, impermeable to dust, water, humidity and / or gases, especially air.

[0033] The opening in the housing base is adapted to the shape of the contact element (e.g. the opening has the same shape and an area equal to or even smaller than the cross-sectional area of ​​the contact element) in such a way that when the contact element is pushed out, the edge of the opening is pushed to the side due to the soft, flexible material of the housing pot, without the edge of the opening turning outwards. In this way, the entire surface of the inside of the opening lies against the contact element that has been pushed through, whereby the press fit thus formed between the contact element and the inside of the opening is impermeable to dust, water, humidity and / or gases, in particular air. State-of-the-art housing pots are made of a harder material, which is why in these housing pots the edge of the opening in the housing base does turn outwards when the contact element is pushed through.Due to this distortion of the opening, the inside of the respective opening can only contact the through-passing contact element with a small area, which in turn leads to leaks in the formed press fit. Furthermore, if the edge area of ​​the opening in the housing base is turned outwards, a slight excess pressure within the built-in plug (e.g. triggered by temperature fluctuations within a short period of time) is sufficient to force open the edge area and thus lead to further leaks in the formed press fit. Such sensitivity to pressure fluctuations does not exist in the built-in plug according to the invention, since the inside of the respective opening rests with its entire surface against the through-passing contact element and the resulting press fit between the contact element and the inside of the opening is thus significantly more stable.

[0034] In a further embodiment of the recording system according to the invention, the element of the housing base is designed as a wall-like elevation (rising into an inner region of the housing pot) surrounding the opening of the housing base and the counter element of the contact element carrier is designed as a raised receiving area formed on the contact element carrier to receive the contact element, or the element of the housing base is designed as a depression having the opening of the housing base and the counter element of the contact element carrier is designed as a raised receiving area formed on the contact element carrier to receive the contact element.

[0035] In a further embodiment of the receiving system according to the invention, the flange-like projection has a sealing lip surrounding the flange-like projection, wherein the sealing lip is arranged on a side of the flange-like projection directed opposite to an insertion direction of the contact element carrier into the insertion opening of the housing pot, and is designed to be pressed against the rear side of the installation plate when the support ring is fastened to the rear side of the installation plate by means of the fastening means, in order to provide a contact area between the flange-like projection and the rear side of the installation plate which is impermeable to dust, water, air humidity and / or gases, in particular air.

[0036] In a further embodiment of the receiving system according to the invention, the flange-like projection has a recess adapted to the bore of the support ring for the passage of the fastening means, in particular wherein the diameter of the recess corresponds at least approximately to the diameter of the bore.

[0037] In a further embodiment of the recording system according to the invention the support ring has a mounting flange extending radially outwards, in particular on a side of the support ring facing opposite to the direction in which the housing pot is passed through the support ring (in other words: on a side of the support ring from which the housing pot can be passed through the support ring), the mounting flange of the support ring has the bore, the housing pot can be passed through the support ring to such an extent that the housing pot abuts the mounting flange of the support ring with the flange-like projection, and / or a radial extension of the flange-like projection and a radial extension of the mounting flange are at least approximately equal, in particular wherein the flange-like projection lies at least approximately congruently on the mounting flange.

[0038] In a further embodiment of the recording system according to the invention the support ring has a shell surface that extends axially through the support ring in the direction in which the housing pot is passed through the support ring, the bore of the support ring is designed as a blind bore, in particular a one-piece blind bore, which is arranged on an outer side of the shell surface of the support ring, the blind bore is arranged on the outer side of the shell surface of the support ring in such a way that the blind bore is flush with the mounting flange on the side of the support ring facing opposite to the direction in which the housing pot is passed through the support ring, in particular wherein an opening of the blind bore extends within the mounting flange, and / or the support ring has two, in particular diagonally opposite, blind bores, in particular wherein the openings of the two blind bores extend within diagonally opposite corners of the mounting flange.

[0039] In a further embodiment of the receiving system according to the invention, the support ring has a recess on the side of the support ring facing opposite to the direction in which the housing pot is passed through the support ring, into which a correspondingly designed counterpiece elevation arranged on a side of the flange-like projection facing in the direction in which the housing pot is passed through the support ring (corresponds to the direction in which the contact element carrier is inserted into the insertion opening of the housing pot) can be inserted with a precise fit, so that a central axis of the housing pot and a central axis of the support ring are coaxial, and / or the housing pot can be fixed to the support ring by means of a press fit that can be formed between the elevation of the flange-like projection and the recess of the support ring.

[0040] In a further embodiment of the receiving system according to the invention, the housing pot has a recess on the side of the housing pot facing opposite to the direction of insertion of the contact element carrier into the insertion opening of the housing pot, into which a flange of the contact element carrier, designed as a counterpart, can be inserted with a precise fit, so that the central axis of the housing pot and a central axis of the contact element carrier are coaxial, the contact element carrier can be fixed to the housing pot by means of a press fit that can be formed between the flange of the contact element carrier and the recess of the housing pot, and / or a plug-in end of the contact element carrier and the plug-in end of the housing pot form a flat surface, wherein the flat surface is designed to be placed against the rear side of the mounting plate.

[0041] In a further embodiment of the receiving system according to the invention, the receiving system further comprises a second support ring, wherein the second support ring is intended to be fastened to the front of the mounting plate by means of the fastening means, wherein the front of the mounting plate is directed from where the cable connector can be brought up to the built-in connector - which is in the mounted state on the mounting plate - the second support ring has a radially outwardly extending support flange, and / or the second support ring has at least one recess, in particular extending in a corner of the support flange of the second support ring, in particular wherein the second support ring, the housing pot and the support ring can be arranged on the mounting plate in such a way that ∘ the central axis of the second support ring, the central axis of the housing pot and the central axis of the support ring are coaxial, ∘ the recess of the support flange of the second support ring,the recess of the flange-like projection of the housing pot and the bore of the support ring lie approximately congruent with one another, and / or ∘ the fastening means provided for fastening the receiving system to the mounting plate and for this purpose brought to the front of the mounting plate can be passed through the recess of the support flange of the second support ring, through the recess of the flange-like projection of the housing pot and through the bore of the support ring, in particular wherein when the fastening means is passed through the recess of the support flange of the second support ring, through the recess of the flange-like projection of the housing pot and through the bore of the support ring, the fastening means exerts a respective force on the said components of the receiving system,whereby the second support ring is pressed against the front of the mounting plate and the flange-like projection of the housing pot and the support ring are pressed against the back of the mounting plate, thus strengthening the attachment of the mounting system to the mounting plate.

[0042] In a further embodiment of the receiving system according to the invention, the second support ring has a locking mechanism for the cable connector to provide a mechanically lockable plug connection, in particular wherein an interior of the second support ring designed to pass through and / or receive the cable connector has a mechanical locking element which is provided to cause an engagement of a lock of the cable connector, which is connected to the lock slide, into the locking element of the second support ring as part of a locking mechanism of the second support ring, which can be actuated by moving a locking slide on the cable connector side, and thus to block the cable connector with respect to rotation in an unscrewing direction which is directed opposite to a screwing-in direction.

[0043] In a further embodiment of the receiving system according to the invention, a separating element is arranged on an outer side of the housing base, wherein the separating element is designed to insulate, in particular electrically, the part of the contact element which passes through the opening in the housing base and is present on the outer side of the housing base from contact with, in particular from, further contact elements.

[0044] The invention also relates to a built-in connector for establishing a plug connection, in particular a mechanically lockable one, with a cable connector that is matched to the built-in connector as a counterpart and that can be inserted into an opening of the built-in connector, wherein establishing the plug connection between the built-in connector and the cable connector enables signal transmission, in particular a power supply signal, a digital signal or an analogue signal, wherein the built-in connector comprises: at least one contact element, wherein the at least one contact element is provided to come into contact with a cable connector-side contact element counterpart by entering into the plug connection and thereby to provide signal transmission across the plug connection, and a contact element carrier, wherein the at least one contact element is received by the contact element carrier, where the built-in connector further comprises a receiving system according to one of the aforementioned aspects / embodiments, wherein the housing pot is guided through the support ring until the flange-like projection abuts, and the contact element carrier together with the at least one contact element is at least partially inserted into the housing pot of the receiving system through the insertion opening.

[0045] The at least one contact element is received by the contact element carrier in such a way, for example, that a first partial region of the contact element is inserted into the contact element carrier and is fixed there, for example, by hooking or clamping, while a second partial region of the contact element protrudes from the receiving region of the contact element carrier. Since the contact element carrier is inserted so far into the housing pot that this receiving region abuts the housing base or the cavity formed by the wall-like elevation on the housing base, the second partial region of the contact element protruding from the receiving region slides out of the housing pot through the opening in the housing base. Consequently, it can also be said that the at least one contact element is at least partially received by the contact element carrier and thus at least partially fixed within the flush-type connector.

[0046] In a further embodiment of the built-in connector according to the invention, the contact element carrier has a locking mechanism for the cable connector to provide a mechanically lockable plug connection, in particular wherein an interior of the contact element carrier designed to receive the cable connector a mechanical retaining element which is provided, as part of a first part of a locking mechanism which can be actuated by rotation of the cable connector in a screwing-in direction when the cable connector is at least partially inserted into the interior, to block a cable connector-side retaining element counterpart with respect to an axial movement in the cable connector withdrawal direction, and / or a mechanical closing element which is provided, as part of a second part of the locking mechanism which can be actuated by moving a cable connector-side locking slide, to cause an engagement of a lock of the cable connector connected to the locking slide in the closing element and thus to block the cable connector with respect to a rotation in the unscrewing direction, which is directed opposite to the screwing-in direction.

[0047] In a further embodiment of the built-in connector according to the invention, the built-in connector is provided to connect the mechanically lockable plug connection with a cable connector of the type 3-pin power connector, in particular wherein the panel connector is designed as a 3-pin power supply chassis socket, or the following cable connector types o IEC, ∘ XLR, ∘ RJ45, ∘ HDMI, ∘ USB, or ∘ RCA, in particular, wherein the built-in connector is designed as a chassis socket adapted to this type of cable connector.

[0048] In a further embodiment of the built-in connector according to the invention, the retaining element is arranged and designed such that the retaining element counterpart engages behind the retaining element after actuation of the first part of the locking mechanism.

[0049] In a further embodiment of the built-in connector according to the invention, the mechanical retaining element is designed as a groove arrangement, wherein grooves of the groove arrangement first extend axially and thereby serve in particular as key counterparts for key elements of the cable connector, and then run normal to the axis or slightly obliquely to the axis and serve in this region as a retaining component, wherein the retaining element counterpart is designed as a nose arrangement which is inserted into the groove arrangement when the plug connection is inserted and is blocked against axial withdrawal by the groove arrangement region running normal or slightly obliquely to the axis, or the mechanical retaining element is designed as a nose arrangement and the retaining element counterpart as a groove arrangement, wherein grooves of the groove arrangement - in the plugged-in state - first extend axially and thereby serve as key elements for the nose arrangement which serves in particular as key counterparts,and then run normal to the axis or slightly oblique to normal to the axis, whereby by entering the plug connection the groove arrangement area extending normal or slightly oblique to normal to the axis engages behind the nose arrangement and thereby the cable connector is blocked against axial withdrawal.

[0050] In other words, the groove of the corresponding element initially runs axially and then becomes a transverse groove, i.e. is designed as an at least largely L-shaped groove. The corresponding nose of the corresponding element, which is designed as a counterpart, is initially guided through the axial section of the at least largely L-shaped groove and then engages in the transverse groove as soon as a rotational movement is carried out, e.g. of the cable connector having the noses. Thus, during a movement in the axial direction or counter to the axial direction, e.g. when the cable connector is pushed in or pulled out, the nose strikes the transverse groove, which prevents, for example, unplanned withdrawal of the cable connector and thus unplanned interruption of the plug connection.

[0051] In a further embodiment of the built-in connector according to the invention, the retaining element is arranged and provided with an oblique course such that by and upon actuation of the first part of the locking mechanism, the retaining element counterpart is moved along the oblique course until the retaining element counterpart encounters a rotary stop and thus a final insertion position of the cable connector in the interior is reached.

[0052] In a further embodiment of the built-in connector according to the invention, the interior space has mechanical key counterparts which are provided to interact with matching key elements of the cable connector in such a way that the cable connector can be inserted into the built-in connector in only one specific rotational orientation predetermined by the key counterparts.

[0053] In a further embodiment of the built-in connector according to the invention, the contact element carrier is made of the same material as the support ring.

[0054] In a further embodiment of the built-in connector according to the invention, the flange of the contact element carrier is made of the same material as the contact element carrier, in particular wherein the material of the contact element carrier and the flange of the contact element carrier is harder than the material of the housing pot,

[0055] In a further embodiment of the built-in connector according to the invention, the flange of the contact element carrier consisting of the harder material is provided to form a stop when the flat surface formed by the plug-in end of the contact element carrier and the plug-in end of the housing pot is placed against the rear of the mounting plate and the receiving system and the contact element carrier are fastened to the rear of the mounting plate by means of the fastening means, so that deformation of the housing pot consisting of the softer material can be prevented by a contact pressure caused by the fastening means.

[0056] In a further embodiment of the built-in connector according to the invention, the flange of the contact element carrier has a recess, in particular open towards an outer side of the flange, adapted to the bore of the support ring and / or the recess of the flange-like projection for the passage of the fastening means, in particular wherein the diameter of the recess of the flange of the contact element carrier corresponds at least approximately to the diameter of the bore of the support ring and / or the recess of the flange-like projection.

[0057] In a further embodiment of the built-in connector according to the invention, the flange of the contact element carrier has two, in particular diagonally opposite, recesses for the respective passage of the fastening means, in particular wherein the recesses of the flange of the contact element carrier extend within diagonally opposite corners of the flange of the contact element carrier.

[0058] In the case of the built-in connector according to the invention, the fixing of the contact element carrier in the housing pot, the fixing of the housing pot in the support ring, and / or the fixing of the contact element in the contact element carrier is achieved by means of appropriately designed press fits (e.g., the press fit between the element and the counter element, the press fit between the recess of the support ring and the elevation of the flange-like projection, or the press fit between the flange of the contact element carrier and the recess of the housing pot) or clamping mechanisms (e.g., between the contact element carrier, in particular the receiving area of ​​the contact element carrier, and the contact element) in combination with the contact pressure exerted by the fastening means. Consequently, in the embodiment of the built-in connector according to the invention shown, the use of adhesives or other fixing means, such as additional clamps, screws, etc., is unnecessary.can be dispensed with, which makes the assembly of the built-in connector according to the invention easy.

[0059] Because the housing pot is made of a soft, flexible material that is slightly pushed to the side when components are inserted, but due to its flexibility only deforms elastically and thus conforms to the component, the press fits between the soft housing pot and the corresponding components, in particular the press fit between the inside of the opening in the housing base and the contact element, are already sealed against dust, water, humidity and / or gases, in particular air, even without the additional use of sealants such as adhesives, sealing pastes, sealing rings (e.g. O-rings), etc. Consequently, the receiving system orthe built-in connector according to the invention simplifies the creation of a seal against dust, water, humidity and / or gases, in particular air, thereby enabling outdoor use, reducing the risk of short circuits and / or meeting certain standards without additional work. Brief description of the drawings

[0060] The receiving system and the built-in connector according to the invention are described in more detail below using exemplary embodiments schematically illustrated in the figures. Identical elements are identified by the same reference numerals in the figures. The described embodiments are generally not drawn to scale and are not to be understood as limiting.

Detailed description of the drawings

[0061] The Figures 1A and 1Bshow perspective views of an exemplary embodiment of the built-in connector 1 according to the invention comprising an exemplary embodiment of the receiving system 2 according to the invention in an exploded view.

[0062] In the exemplary embodiment shown, the receiving system 2 comprises the housing pot 3 and the support ring 4. The housing pot 3 has, at its insertion-side end 5, the insertion opening 6 through which the contact element carrier 7 can be at least partially inserted into the housing pot 3, the (circular) housing base 8 opposite the insertion-side end 5, and the cylindrical housing shell 9 extending from the insertion opening 6 to the housing base 8.

[0063] The housing pot 3 further comprises, at the insertion opening 6, the flange-like projection 10 extending in the radial direction, which is surrounded by the sealing lip 11, and the recess 13 arranged on the side 12 of the housing pot 3 facing opposite to the insertion direction of the contact element carrier 7 into the insertion opening 6 of the housing pot 3. The recess 13 is intended to precisely accommodate the flange 14 of the contact element carrier 7 and extends within the flange-like projection 10 into the two diagonally opposite corners 15 of the flange-like projection 10, in which the recesses 16 for the passage of the fastening means are arranged.

[0064] The raised portion 18 is arranged on the side 17 of the flange-like projection 10 facing in the direction in which the housing cup 3 passes through the support ring 4. The raised portion 18 is designed to fit precisely into the correspondingly formed counterpart recess 19 of the support ring and also extends into the two diagonally opposite corners 15 of the flange-like projection 10, in which the recesses 16 for the passage of the fastening means are arranged. In the exemplary embodiment shown, the raised portion 18 of the flange-like projection 10 is formed by the recess 13 of the flange-like projection 10.

[0065] In the exemplary embodiment shown, three openings 20 extend within the housing base 8 for the respective passage of at least some of the three contact elements 21 which are received by the contact element carrier 7.

[0066] In the exemplary embodiment shown, the housing pot 3 has, on the side 17 of the housing base 8 directed in the direction in which the housing pot 3 is passed through the support ring 4 (in other words: on the outside 17 of the housing base 8), a separating element 22 consisting of three separating walls extending from a common point, which separates the parts of the three contact elements 21 passed through the three openings 20 in the housing base 8 and present on the outside 17 of the housing base 8 from one another in such a way that no unplanned contact of the contact elements 21 with other electrically conductive components (e.g. with a stranded wire intended for another contact element) can occur, which could under certain circumstances lead to a short circuit.

[0067] The support ring 4 has the mounting flange 23, which has at least approximately the same radial extension as the flange-like projection 10, which is why the mounting flange 23 and the flange-like projection 10 lie at least approximately congruent with one another during assembly of the exemplary embodiment shown of the flush-type connector 1. The support ring 4 also has a cylindrical jacket surface 24 that expands axially in the direction in which the housing pot 3 is passed through the support ring 4, wherein the inner diameter (or the radial extension / dimension) of the support ring jacket 24 is adapted to the diameter (or the radial extension / dimension) of the cylindrical housing pot 3, in particular to the diameter (orthe radial extension / dimension) of the cylindrical housing shell 9, is adapted in such a way that the housing pot 3, which is passed through the support ring 4 in the direction of passage, rests with the outer side 26 of the housing shell 9 on the inner side 27 of the support ring shell 24, whereby the support ring 4 supports the housing pot 3.

[0068] In the exemplary embodiment of the built-in connector 1 according to the invention shown, the flange-like projection 10 of the housing pot 3 has the sealing lip 11 surrounding the flange-like projection 10, wherein the sealing lip 11 - when the flat surface 28 formed by the contact element carrier 7 and the housing pot 3 is placed on the rear side of the mounting plate - is pressed against the rear side of the mounting plate and thus seals the contact area between the flange-like projection 10 and the rear side of the mounting plate against dust, water, air humidity and / or gases, in particular air.

[0069] In the embodiment shown, the support ring 4 has two one-piece blind bores 30 arranged diagonally opposite one another on the outer side 29 of the lateral surface 24 of the support ring 4, wherein the blind bores 30 are designed at least largely as hollow cylinders open on one side, the respective lateral surface of which (the (blind) bores do not necessarily have to have a cylindrical or at least approximately cylindrical lateral surface) is formed at least partially by the lateral surface 24 of the support ring 4.The blind holes 30 are arranged at two diagonally opposite corners 31 of the mounting flange 23 and end flush with the mounting flange 23 on the side 32 of the support ring 4 facing opposite to the direction in which the housing pot 3 passes through the support ring 4, wherein the openings of the blind holes 30 extend within the diagonally opposite corners 31 of the mounting flange 23, wherein the two openings of the blind holes 30 are located in the recess 19 of the mounting flange 23 extending into the two corresponding diagonally opposite corners 31 of the mounting flange 23.

[0070] At the two further diagonally opposite corners 33 of the mounting flange 23, at which no blind bore 30 is arranged, a support structure 34, in particular designed as a triangle, is arranged on the side 17 of the mounting flange 23 directed in the direction of passage of the housing pot 3 through the support ring 4, wherein the respective support structure 34 extends to the outer surface 24 of the support ring 4 and is also arranged there. This embodiment has the advantage that the support ring 4, in particular the mounting flange 23 of the support ring 4, does not warp even when the fastening means are firmly tightened, and thus the desired support effect is ensured even when the receiving system 2 or the built-in connector 1 according to the invention is mounted on the rear of the mounting plate.

[0071] In the embodiment shown, the housing base 8 has three elements 35, each of which is designed as a wall-like elevation (rising into the interior of the housing pot) surrounding one of the three openings 20 of the housing base 8. A corresponding counter-element 36 of the contact element carrier 7, designed as a raised receiving area for receiving the contact element 21 on the contact element carrier 7, engages in each of the cavities formed by the wall-like elevations 35, wherein the respective wall-like elevation 35 bears against the respective counter-element 36 and the contact area formed thereby (in other words, a press fit) fixes the contact element carrier 7 in the housing pot 3 and is also impermeable to dust, water, humidity and / or gases, in particular air.

[0072] The Figures 2A and 2Bshow perspective views of an exemplary embodiment of the built-in connector 1 according to the invention comprising an exemplary embodiment of the receiving system 2 according to the invention in the assembled state. Figure 2Ashows the insertion-side end 37 of the contact element carrier 7 and the insertion-side end 5 of the housing pot 3, wherein the contact element carrier 7 is pushed into the housing pot 3 so far that the flange 14 of the contact element carrier 7 engages precisely in the recess 13 arranged on the side 12 of the housing pot 3 facing opposite to the direction of insertion of the contact element carrier 7 into the insertion opening 6 of the housing pot 3 (or also: on the side 12 provided for the installation of the receiving system or the built-in connector on the installation plate as the installation plate side) of the housing pot 3 and the flat surface 28 is formed there. This flat surface 28, which is arranged on the side 12 provided for the installation of the receiving system orof the built-in connector on the mounting plate is designed as the mounting plate side of the built-in connector, can then be placed against the rear of the mounting plate, whereby the circumferential sealing lip 11 of the housing pot 3 rests against the rear of the mounting plate. The housing pot 3 is also passed through the support ring 4 to such an extent that the flange-like projection 10 of the housing pot 3 abuts the mounting flange 23 of the support ring 4 and the elevation 18 of the flange-like projection 10 engages precisely in the recess 19 arranged on the side 32 of the support ring 4 facing opposite to the direction in which the housing pot 3 is passed through the support ring 4.The flange-like projection 10 lies at least approximately congruently on the mounting flange 23 and the contact element carrier 7, the housing pot 3 and the support ring 4 are arranged such that the central axis of the contact element carrier 7, the central axis of the housing pot 3 and the central axis of the support ring 4 are coaxial.

[0073] In the arrangement of contact element carrier 7, housing pot 3 and support ring 4 as in the exemplary embodiment of the inventive built-in connector 1 shown, the two recesses 38 of the flange 14 of the contact element carrier 7, the two recesses 16 of the flange-like projection 10 and the two openings of the blind bores 30 of the support ring 4 are located in the diagonally opposite corners 15, 31, 39 of the respective component 3, 4, 7 in such a way that one of the two recesses 38 of the flange 14 of the contact element carrier 7, the two recesses 16 of the flange-like projection 10 and the two openings of the blind bores 30 of the support ring 4 are approximately congruent with one another, wherein the diameter of the recess 38 of the flange 14 of the contact element carrier 7, the diameter of the opening of the blind bore 30 of the Support ring 4 and the diameter of the recess 16 of the flange-like projection 10 are at least approximately equal.

[0074] If the flat surface 28, in particular with the circumferential sealing lip 11 of the housing pot 3, is now placed against the rear of the mounting plate and a fastening means (e.g. a screw) is guided from the front of the mounting plate through the mounting plate until the fastening means engages in the blind bore 30, the fastening means is automatically also guided through the recess 38 of the flange 14 of the contact element carrier 7 and the recess 16 of the flange-like projection 10. If the fastening means is now tightened, the support ring 4 is pulled towards the rear of the mounting plate and the flat surface 28, in particular the sealing lip 11 of the housing pot 3, is pressed against the rear of the mounting plate.Because the housing pot 3 is made of the soft material, the flange-like projection 10 of the housing pot 3 is pressed against the rear of the mounting plate by the contact pressure exerted by the fastening means, whereby a slight compression of the flange-like projection 10 and the sealing lip 11 occurs, whereby the contact surface of the inventive built-in connector 1 with the rear of the mounting plate becomes sealed against dust, water, humidity and / or gases, in particular air, even without the use of additional sealing means such as adhesives, sealing pastes, sealing rings (e.g. O-rings), etc. Excessive deformation of the flange-like projection 10 of the housing pot 3, in particular around the recesses 16 of the flange-like projection 10, due to overtightening of the fastening means is prevented, as previously described, by the stop formed by the hard contact element carrier 7.

[0075] In the Figures 1A to 2B In the exemplary embodiments shown, the contact element carrier 7 is designed such that the inventive built-in connector 1 is a male built-in connector (also referred to as a male built-in connector or male device connector). For this purpose, the interior space 40 of the contact element carrier 7, designed to accommodate the cable connector, has the mechanical retaining elements 41 designed as grooves and the mechanical locking element 42 provided for the latch of the latch slide on the cable connector side. Before fastening the inventive built-in connector 1, the insertion opening 43 provided for inserting the cable connector into the built-in connector 1 is aligned with a corresponding recess in the mounting plate.

[0076] The Figure 3shows a perspective view of an exemplary embodiment of the inventive built-in connector 1 comprising an exemplary embodiment of the inventive receiving system 2 in the assembled state. In this exemplary embodiment, the contact element carrier 7 is designed such that the inventive built-in connector 1 is a female built-in connector (also referred to as a female built-in connector or female device connector). In the female built-in connector 1 shown, a support element 52 is arranged in the contact element carrier interior 40, rising from the contact element carrier interior 40 counter to the insertion direction 12 of the cable connector into the contact element carrier 7, said support element having the mechanical retaining elements 41 designed as lugs.Among other things, because the contact element carrier interior 40 of the female built-in connector 1 must accommodate or contain the support element 52 in addition to the cable connector, the contact element carrier 7 of the female built-in connector 1 according to the invention has a larger diameter (in other words: a larger radial extension / dimension) than that in the . Figures 1A to 2Bshown contact element carrier 7 of the male built-in connector 1 according to the invention. So that this enlarged contact element carrier 7 can be received by the receiving system 2 according to the invention, the housing pot 3 and the support ring 4 must each also be designed with an enlarged diameter or with an enlarged radial extent. However, since the built-in connector 1 according to the invention is intended to have certain standardized dimensions (with regard to the spatial extent, in particular also with regard to the radial extent), e.g., the so-called D dimension, in the embodiment shown, the jacket of the outer surface of the contact element carrier 7, the jacket of the housing pot 3, and the jacket 24 of the support ring 4 are not designed with a circular cylindrical shape, since otherwise the radial extent of the built-in connector 1 according to the invention would exceed the desired dimension.Instead, the lateral surfaces of the respective components 3, 4, 7 are each flattened on at least one side, in particular on two diametrically opposite sides, in such a way that the radius is reduced on the flat surface 51 thus formed (e.g., the radial extension of the support ring 4 is flush with the radial extension of the flange-like projection 10 of the housing pot 3), whereby the radial extension of the built-in connector 1 according to the invention is limited and the desired standardized dimension, in particular the D dimension, is thus maintained. In other words, the lateral surfaces of the respective components 3, 4, 7 each run on at least one side along a secant running through the respective lateral surface, so that a flat surface 51 is formed on this side.

[0077] In general, it is understood that the terms "cylinder" and "cylindrical" are not limited to circular cylinders, but rather refer to all types of cylinders, in particular elliptical cylinders or circular cylinders in which at least one side is flattened or in which at least a portion of the lateral surface is formed with an enlarged or reduced radius. Furthermore, it is understood that the support ring 4 does not necessarily have to have the shape of a circular ring. The term support ring also refers to an annular body in which, as in, for example, Figure 3 As shown, at least a portion of the circumference deviates from a circular shape, or a portion of the lateral surface deviates from a circular-cylindrical shape. For example, the support ring 4 can also have the shape of a hexagon nut or a hollow cuboid.

[0078] In the illustrated embodiment of the inventive flush-type connector 1, the interior space 40 of the contact element carrier 7, designed to accommodate the cable connector, does not have the mechanical locking element 42 provided for the latch of the cable connector-side locking slide. In the illustrated embodiment, the locking element 42 is provided to be arranged on a correspondingly designed second support ring 54.

[0079] The Figure 4shows a schematic representation of the assembly of an exemplary embodiment of the built-in connector 1 according to the invention on a mounting plate 53, wherein the receiving system 2 and thus also the assembled built-in connector 1 in the embodiment shown has the second support ring 54. The second support ring 54 is brought up to the mounting plate 53 from the front in such a way that the second support ring 54, with its opening, surrounds the recess in the mounting plate 53 provided for the passage of the cable connector. Furthermore, the second support ring 54 also has a support flange, wherein recesses provided for the passage of fastening means extend into two opposite corners of the support flange of the second support ring.When the illustrated embodiment of the inventive flush-type connector 1 is properly assembled, the center axis of the housing cup 3, the center axis of the support ring 4, and the center axis of the second support ring 54 are coaxial. Furthermore, the recesses of the support flange of the second support ring 54, the recesses 38 of the flange 14 of the contact element carrier 7, the recesses 16 of the flange-like projection 10, and the openings of the blind bores 30 of the support ring 4 are approximately congruent with one another, with the diameter of the recesses of the support flange of the second support ring 54, the diameter of the recesses 38 of the flange 14 of the contact element carrier 7, the diameter of the openings of the blind bore 30 of the support ring 4, and the diameter of the recesses 16 of the flange-like projection 10 being at least approximately equal. If a fastening device 55 (e.g.If a screw 55 is guided from the front through a recess in the support flange of the second support ring 54, the fastening means 55 is accordingly also guided through the recesses 38 in the flange 14 of the contact element carrier 7, the recesses 16 in the flange-like projection 10, and the openings of the blind bores 30 in the support ring 4, until the fastening means 55 then engages in the blind bore 30 and the components 3, 4, 7, 54 are thus pulled together and fastened. Because the illustrated embodiment of the built-in connector 1 according to the invention is supported on the mounting plate 53 from both the front and the rear, and the fastening means 55 is guided from the front to the rear through all of the components 3, 4, 7, 54, the fastening of the built-in connector 1 to the mounting plate 53 is reinforced.

[0080] It is understood that these figures only schematically depict possible embodiments. The various approaches can also be combined with each other and with prior art methods.
