Flush-mounted plug connector with mounting system and housing made of soft material

Description

Field of 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 in order to form part of a panel-mount connector. Background of the invention

[0002] Panel-mount connectors with a multi-part design are known from the prior art, including disclosures in US 5,123,862 and CN 218548966 U. In these connectors, 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 provides the interior space into which the cable connector is inserted to establish contact with the contact pins. This interior space may also include locking elements for the cable connector. Furthermore, in specific embodiments of such panel-mount connectors, the contact carrier provides a flange designed to support the contact carrier, and thus the panel-mount connector, against a recess in the mounting plate.The flange may also have mounting holes through which, for example, screws can be inserted to attach the panel-mount connector to the mounting plate. US 5,123,862 describes a connector that has a soft housing with an outwardly projecting flange portion and a metallic fastener for attaching the connector to a mounting plate. A lateral projection of the contact carrier body is clamped between the fastener and the mounting plate.

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

[0004] In state-of-the-art panel-mount connectors, the entire receiving system or connector housing is manufactured from a hard, inelastic material (e.g., a harder thermoplastic), whereby this harder housing does not fit tightly against the contact pins that protrude through the housing openings. Consequently, these press fits between the state-of-the-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 a particular problem in outdoor applications of the panel-mount connector (e.g., loudspeakers at open-air festivals). Rain can occur at any time, allowing water to penetrate the panel-mount connector if no cable connector is plugged in and the sealing cap, intended for temporary closure and sealing of the connector's interior, is not in place. The water can then seep up to the press fit between the panel-mount connector housing and the contact pin and accumulate there.Since this press fit, as mentioned previously, is not watertight due to the harder housing material, especially with regard to water, there is a risk with state-of-the-art built-in connectors that 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-mount connectors solve the described problem by additionally sealing the contact points between the contact pins and the housing with sealants such as adhesives, sealing pastes, sealing rings (e.g., O-rings), etc. However, this reveals a disadvantage of state-of-the-art panel-mount connector housings and connectors, as these additional components / sealing materials incur both additional costs (e.g., material procurement costs, additional machinery / personnel) and additional labor due to further work steps. For example, before assembling the panel-mount connector by connecting the mounting system or panel-mount connector housing, contact carrier, and contact pins, the corresponding sealing rings must be inserted / fitted or the still-liquid adhesive applied. Object of the invention

[0007] It is therefore an object of the invention to provide a receiving system and a built-in connector that overcome the disadvantages of the prior art, especially in light of the strict requirements regarding safety and the globally established installation dimensions.

[0008] Another task is to provide a receiving system and a built-in connector which simplifies the process of creating a seal against dust, water, humidity and / or gases, especially air, thereby enabling outdoor use, reducing the risk of short circuits and / or meeting certain standards without additional effort.

[0009] These problems are solved by realizing at least some of the characterizing features of the independent claims. Features that further develop the invention in an alternative or advantageous way can be found in some of the remaining features of the independent claims and in the dependent 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 in order to form a part of a panel-mount 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 at a plug-in end (or also: at a side / end intended for installation of the receiving system or the plug-in connector on a mounting plate as the mounting plate-side side) of the housing pot, wherein a flange-like projection is arranged at the insertion opening of the housing pot, and the receiving system is designed 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 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 with the flange-like projection abuts the support ring, 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 back of the mounting plate by means of a fastening means which passes from a front of the mounting plate through the mounting plate and engages in the bore.

[0011] The inventive design of the receiving system / panel-mount connector with a housing pot made of a softer, more elastic material than in receiving systems / panel-mount 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, firstly, the housing pot fits snugly against the contact element carrier when it is inserted, which is made, for example, of a harder plastic (e.g., a harder thermoplastic), and secondly, the opening of the housing base fits snugly against the inserted contact element.In other words, the opening of the housing base has a slightly smaller area than the cross-sectional area of ​​the portion of the contact element that is pushed out of the housing base through the opening. As the contact element is pushed out, requiring a certain force, the opening of the housing base expands. The area extending into the opening of the housing base then presses against the contact element with a force that counteracts this expansion, creating a so-called press fit between the opening and the contact element. Because the housing base of the inventive receiving system / connector is made of a softer, more elastic material (for example, comparable to rubber), it can expand more easily and conform better to the contact element.In this way, the press fits between the soft, elastic housing cup and the harder, inelastic contact element are impermeable to dust, water, humidity and / or gases, especially air, so that the entire panel-mount connector, when installed, is sealed against dust, water, humidity and / or gases, especially air, even if, for example, the sealing cap was forgotten to be placed over the insertion opening of the panel-mount connector during rain, and water could thereby enter the panel-mount connector.

[0012] Due to the watertight and airtight press fit between the soft, elastic housing cup and the at least one contact element, the inventive connector, which incorporates the mounting system according to the invention, is able to meet the IP65 and IP67 standards even without a sealing cap in place or a cable connector inserted, without the need for additional components or sealing materials (such as a liquid sealant that hardens after application). Consequently, the inventive mounting system / installable connector eliminates both additional costs (e.g., material procurement costs, additional machinery / personnel) and additional labor costs that would otherwise be incurred through further work steps. These additional costs and work steps are therefore not required with the inventive mounting system / installable connector because of the watertight and airtight seal.Airtight press fits mean no further sealing is necessary, thus overcoming the disadvantages of the state of the art.

[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, particularly in the range of 75 to 95. When selecting the hardness of the material, or the composition of the components that provide the material's hardness, the aspects of sealing and processability must be considered. If the material is chosen to be too hard, processability, especially by injection molding, is simplified, but the sealing effect is reduced. With a material that 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 injection molding). Particularly with a Shore A hardness in the range of 65 to 95, both sealing and processability of the housing pot are ensured.

[0014] Because the support ring in the inventive receiving system is made of a harder material, the support ring does not warp when the fasteners are tightened or when the plug connector is assembled, which is why the support ring can exert an increased and also moreover constant support 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 from a softer material compared to the prior art, without the soft, flexible housing pot becoming brittle. During the assembly of the inventive panel-mount connector, e.g., during the insertion of the contact element carrier and / or the pushing out of the contact elements from the openings in the housing base, during the insertion of the fastening means or during the tightening of the corresponding fastening means, which then exert a certain contact pressure on the housing pot, through the rotational or lever forces exerted by a cable connector inserted into the contact element carrier, through the tensile forces acting on the housing pot caused by strands and / or clamps that are attached to the inserted contact elements, and / or through the force of gravity acting on the housing pot, warps / deforms, thus making contact areas between the components, especially between the insides of the openings in the housing base and the respective contact elements, leaky to dust, water, humidity and / or gases, especially 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 the material of the contact element carrier has a Shore D hardness in the range of 60 to 100.

[0017] Although a primary function of the contact element carrier is to hold the contact elements (also called pins or sheets), particularly the three contact elements, the term "contact element carrier" encompasses more than just a simple contact element holder. Rather, the contact element carrier also provides the socket for the cable connector and locking elements for securing the cable connector within this socket. Furthermore, in certain embodiments, the contact element carrier incorporates the flange through which mounting hardware (e.g., screws) is inserted to attach the contact element carrier to the mounting plate (e.g., a speaker enclosure). Thus, the contact element carrier also serves as a kind of skeleton or support structure that accommodates the other components of the panel-mount connector.is surrounded by it, and, as a supporting and shaping structure, spans, for example, the interior space of the built-in connector intended for receiving and locking 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 leakage of the built-in connector) and generally stabilizes the inventive receiving system or the inventive built-in connector.Furthermore, the hard insertion-side end and the hard flange of the contact element carrier, especially around the recesses of the contact element carrier's flange, form a hard stop against the back of the mounting plate when the fasteners are tightened. This hard stop prevents the flange-like projection, also made of the soft material and located against the back of the mounting plate, from being compressed so strongly by the contact pressure caused by tightening the fasteners that undesirable deformation of the flange-like projection occurs (e.g., lateral protrusion of the flange-like projection between the back of the mounting plate and the mounting flange of the support ring), particularly at the recesses of the flange-like projection.Such an undesirable deformation of the flange-like projection, especially at the recesses of the flange-like projection, could in turn lead to leaks within the inventive built-in connector.

[0019] The design of the support ring and contact element carrier from a harder, less flexible material than the housing cup facilitates the handling of the mounting system or the plug-in connector. This is because, when mounting the mounting system or the plug-in connector to the mounting plate of a device, the installer can tighten the fasteners (e.g., screws or bolts) firmly until a stop is felt, without the previously described bulging of the flange-like projection occurring. Furthermore, the harder, more robust components reduce the likelihood of damage to the plug-in connector during installation.

[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] The housing material can consist of at least 60%, and in particular at least 80%, of plastic, with additives such as plasticizers or flame retardants mixed into the plastic. For powerCON type panel-mount connectors (powerCON chassis sockets) from Neutrik AG of Liechtenstein, also known as the Neutrik Group, it is particularly important that the housing material is flame-retardant, which is achieved, for example, by adding flame retardants to the housing 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 is manufactured by means of injection molding, 3D printing, pressing 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 others, that the housing pot can be manufactured using injection molding, 3D printing, pressing or vulcanization processes, and that the housing has an insulating effect against electric 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 which would require additional sealing with O-rings or adhesives. This also saves on sealing materials and labor compared to the prior art. Furthermore, several functions are combined within the respective component, which in turn simplifies handling (or assembly, since fewer parts need to be joined).

[0025] The injection molding process enables the simple production of the individual components of the inventive receiving system / connector, and in particular the simple production of the housing. For manufacturing by injection molding, it is necessary that the material used can first be melted and then injected into the appropriate mold. Furthermore, the material must be able to solidify in the mold by cooling and retain this solidified form until reheating. It is therefore particularly advantageous that the materials of the inventive receiving system / connector are a thermoplastic or predominantly made of this thermoplastic (or a combination thereof).thermoplastic elastomers) (often with additives such as plasticizers or flame retardants), since many thermoplastics exhibit the properties described above and are therefore suitable for injection molding. Furthermore, some thermoplastics, especially amorphous thermoplastics such as low-density polyethylene (LDPE), atactic polypropylene (PP-ate), or atactic polystyrene (PS-ate), have a Shore hardness quite close to that 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 panel-mount connector, it is particularly advantageous if the contact element carrier and the support ring are made of a harder material than the housing. Since, in an advantageous embodiment, the contact element carrier and the support ring are manufactured by injection molding, 3D printing, pressing, or vulcanizing, just like the housing, it is particularly advantageous if the material of the contact element carrier and the support ring is a thermoplastic, and especially if it consists predominantly 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] Advantages of manufacturing the individual components of the inventive receiving system / integrated connector using injection molding lie in the fact that, firstly, the injection molding process allows for high-precision manufacturing, and secondly, various components (e.g., plastic and flame retardant) can be mixed together in different proportions according to a specific recipe. Subsequently, it can be tested whether the final product exhibits the desired material properties with the given recipe, and the recipe can be adjusted if necessary.

[0028] A further advantage of one embodiment of the inventive receiving system / flush-mount 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 significant challenge, as materials previously treated with such flame retardants become very hard and brittle, thus losing their sealing properties. Flame retardancy is particularly important for powerCON-type flush-mount connectors, as these connectors must comply with the UL 94 standard (i.e., the material and connector must be V0 certified according to UL 94 at 1 mm). Due to the standards and their requirements, it is advantageous that a flame retardant (a certain proportion of a flame-retardant additive) is added 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 housing material can also be UV-stabilized (according to UN standard UL50E, and therefore requires a UL f1 certificate). For this purpose, UV stabilizers of 10-15 wt% (weight percent), 10-15 mol% (mol percent), or 10-15 vol% (volume percent) are added to the material. Due to the UV stabilization, the inventive mounting system / connector can be used outdoors. The "True Outdoor Protection" (TOP) product series from Neutrik AG of Liechtenstein, also known as the Neutrik Group, can be cited as an example.

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

[0031] In a further embodiment of the receiving system according to the invention, the housing pot also has: a housing base at a rear end of the housing pot opposite the insertion end, and a housing jacket extending from the insertion opening to the housing base, wherein a radial extent (in other words: the diameter or dimension) of the support ring and a radial extent (in other words: the diameter or dimension) of the housing shell are coordinated such 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 thereby supported, in particular wherein the support ring has an axial extent extending in a passage direction of the housing pot through the support ring (corresponding also to: the direction in which the central axis of the housing pot runs from the insertion-side end to the housing base, the insertion direction of the contact element carrier into the housing pot, and the insertion direction of the cable connector into the contact element carrier (or the insertion direction of the cable connector into the panel connector)), such that at least 50% of the housing shell can be supported by the support ring.

[0032] According to the invention, the base of the case has: an opening provided such that, when the contact element carrier together with the contact element is at least partially inserted into the housing pot through the insertion opening to form the part of the built-in connector, at least a part of the contact element is passed through the opening, so that at least the part of the contact element passed through the opening of the housing base is located on an outside of the housing base, and an element circumferentially surrounding the opening of the housing base, which engages with a corresponding counterpart 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 counterpart element. in particular where a contact area formed between the at least partially implemented 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, is 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 in such a way (e.g., the opening has the same shape and an equal or even smaller cross-sectional area than the contact element) that, when the contact element is pushed out, the edge of the opening is pressed to the side by the soft, flexible material of the housing pot, without the edge of the opening turning outwards. In this way, the entire inner surface of the opening rests against the inserted contact element, creating an impermeable press fit between the contact element and the inner surface of the opening, thus preventing the passage of dust, water, humidity, and / or gases, especially air. Prior 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 indeed turn outwards when the contact element is inserted.Due to this distortion of the opening, the inner surface of the opening can only make contact with the inserted contact element over a small area, which in turn leads to leaks in the press fit. Furthermore, if the edge of the opening in the housing base is turned outwards, even a slight overpressure within the connector (e.g., caused by rapid temperature fluctuations) is sufficient to force the edge open, thus causing further leaks in the press fit. The connector according to the invention is not susceptible to such pressure fluctuations because the entire inner surface of the opening makes contact with the inserted contact element, resulting in a significantly more stable press fit between the contact element and the inner surface of the opening.

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

[0035] In a further embodiment of the receiving system according to the invention, the flange-like projection has a sealing lip circumferential to the flange-like projection, wherein the sealing lip is arranged on a side of the flange-like projection that is directed opposite to the insertion direction of the contact element carrier into the insertion opening of the housing pot, and is designed to be pressed against the back of the mounting plate when the support ring is attached to the back of the mounting plate by means of the fastening means, in order to provide a contact area between the flange-like projection and the back of the mounting plate that is impermeable to dust, water, 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, particularly on a side of the support ring opposite to the direction in which the housing pot passes through the support ring (in other words: on a side of the support ring from where the housing pot can be brought towards the support ring for passage), 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 its flange-like projection, and / or the radial extent of the flange-like projection and the radial extent of the mounting flange are at least approximately equal, in particular where 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 cylindrical surface that extends axially in the direction in which the housing pot passes through the support ring, the bore of the support ring is designed as a blind bore, in particular a one-piece bore, which is arranged on an outside of the cylindrical surface of the support ring, the blind bore is arranged on the outside of the cylindrical 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 opposite to the direction in which the housing pot passes 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 blind bores, in particular diagonally opposite, 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 that is directed opposite to the direction in which the housing pot passes through the support ring, into which a correspondingly designed counterpart and arranged on a side of the flange-like projection that is directed in the direction in which the housing pot passes through the support ring (corresponding to the insertion direction of the contact element carrier 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 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 that is directed opposite to the insertion direction of the contact element carrier into the insertion opening of the housing pot, into which a correspondingly designed flange of the contact element carrier can be inserted precisely, 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 formed between the flange of the contact element carrier and the recess of the housing pot, and / or an insertion-side end of the contact element carrier and the insertion-side end of the housing pot form a flat surface, wherein the flat surface is designed to be placed against the back 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 designed to be attached to the front of the mounting plate by means of the fastening means, the front of the mounting plate being directed towards the point from which the cable connector can be brought to the mounting connector in the mounted state on the mounting plate, the second support ring having a support flange extending radially outwards, and / or the second support ring having 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 cup and the support ring can be arranged on the mounting plate such that: ∘ the central axis of the second support ring, the central axis of the housing cup 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 are approximately congruent, and / or ∘ the fastening means provided for attaching the receiving system to the mounting plate and brought to the front of the mounting plate for this purpose 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,This presses the second support ring 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 reinforcing 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 for providing a mechanically lockable plug connection has a locking mechanism for the cable connector, in particular wherein an interior of the second support ring designed for the passage and / or receiving of the cable connector has a mechanical closing element which is provided to effect, within the framework of a locking mechanism of the second support ring, which can be actuated by moving a locking slide on the side of the cable connector, an engagement of a locking bolt of the cable connector connected to the locking slide into the closing element of the second support ring and thus to block the cable connector with respect to rotation in an outward rotation direction which is directed opposite to an inward rotation direction.

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

[0044] The invention further relates to a panel-mount connector for forming a plug connection, in particular a mechanically lockable one, with a cable connector that is matched to the panel-mount connector as a counterpart and can be inserted into an opening of the panel-mount connector, wherein a signal transmission is enabled by forming the plug connection between the panel-mount connector and the cable connector, in particular a power supply signal, a digital signal or an analog signal, wherein the panel-mount connector has: at least one contact element, wherein the at least one contact element is provided to come into contact with a contact element counterpart on the cable connector side by entering the plug connection and thereby 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 passed 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 that a first part of the contact element is inserted into the contact element carrier and fixed there, for example, by hooking or clamping, while a second part of the contact element protrudes from the receiving area of ​​the contact element carrier. Since the contact element carrier is inserted so far into the housing pot that this receiving area abuts the bottom of the housing or the cavity formed by the raised wall on the bottom of the housing, the second part of the contact element protruding from the receiving area is pushed out of the housing pot through the opening in the bottom of the housing pot. 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 panel-mount connector.

[0046] In a further embodiment of the inventive built-in connector, the contact element carrier for providing a mechanically lockable plug connection has a locking mechanism for the cable connector, in particular wherein an interior space of the contact element carrier designed to receive the cable connector a mechanical retaining element which is designed to block a cable connector-side retaining element counterpart with respect to axial movement in the cable connector withdrawal direction within a first part of a locking mechanism, which can be actuated by rotating the cable connector in a screw-in direction while the cable connector is at least partially inserted into the interior, and / or a mechanical closing element which is designed to cause an engagement of a cable connector-side locking slider with respect to the locking element within a second part of the locking mechanism, which can be actuated by moving a cable connector-side locking slider, and thus block the cable connector with respect to rotation in an unscrewing direction opposite to the screw-in direction.

[0047] In a further embodiment of the inventive panel-mount connector, the panel-mount connector is designed to connect the mechanically lockable plug connection with a cable connector. to enter into a 3-pin mains connector, in particular wherein the panel-mount connector is designed as a 3-pin power supply chassis socket, or the following cable connector types: IEC, XLR, RJ45, HDMI, USB, or RCA. to address, in particular where the built-in connector is designed as a chassis socket adapted to this type of cable connector.

[0048] In a further embodiment of the inventive built-in connector, 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 inventive built-in connector, The mechanical retention element is designed as a groove arrangement, wherein the 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 extend perpendicular to the axis or slightly oblique to the axis and serve as a retention component in this area, wherein the retention element counterpart is designed as a lug arrangement which is inserted into the groove arrangement by the insertion of the plug connection and is blocked against axial withdrawal by the groove arrangement area extending perpendicular or slightly oblique to the axis, or the mechanical retention element is designed as a lug arrangement and the retention element counterpart as a groove arrangement, wherein the grooves of the groove arrangement - in the inserted state - first extend axially, and thereby serve as key elements for the lug arrangement which serves in particular as key counterparts.and then run perpendicular to the axis or slightly oblique to the axis, whereby, upon insertion of the plug connection, the groove arrangement area extending perpendicular or slightly oblique to the axis engages behind the lug arrangement, thereby blocking the cable connector against axial withdrawal.

[0050] In other words, the groove of the corresponding element runs axially first and then becomes a transverse groove, thus forming a groove that is at least largely L-shaped. The corresponding tab of the element, designed as its 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, e.g., of the cable connector with the tabs, is performed. Thus, the tab strikes the transverse groove during movement in the axial direction or against the axial direction, e.g., when the cable connector is pushed in or pulled out, thereby preventing, for example, the cable connector from being unintentionally pulled out and thus an unintended interruption of the connection.

[0051] In a further embodiment of the inventive built-in connector, the retaining element is arranged and provided with an inclined path in such a way that, through and when the first part of the locking mechanism is actuated, the retaining element counterpart is moved along the inclined path until the retaining element counterpart meets a rotary stop and thus an end insertion position of the cable connector in the interior is reached.

[0052] In a further embodiment of the inventive built-in connector, the interior has mechanical key counterparts which are designed 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 determined by the key counterparts.

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

[0054] In a further embodiment of the inventive plug connector, 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 inventive plug connector, the flange of the contact element carrier, which is made of the harder material, is designed 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 back of the mounting plate and the receiving system and the contact element carrier are fastened to the back of the mounting plate by means of the fastening means, so that deformation of the housing pot, which is made of the softer material, by a contact pressure caused by the fastening means can be prevented.

[0056] In a further embodiment of the inventive plug connector, the flange of the contact element carrier has a recess, in particular open towards an outside of the flange, which is aligned with 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 inventive plug connector, 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 inventive panel-mount connector, the fixing of the contact element carrier in the housing cup, the fixing of the housing cup in the support ring, and / or the fixing of the contact element in the contact element carrier is achieved by appropriately designed press fits (e.g., the press fit between the element and the mating element, the press fit between the recess of the support ring and the raised section of the flange-like projection, or the press fit between the flange of the contact element carrier and the recess of the housing cup) 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 illustrated embodiment of the inventive panel-mount connector, the use of adhesives or other fixing means, such as additional clamps, screws, etc., is unnecessary.This eliminates the need for additional components, making the assembly of the inventive built-in connector easy.

[0059] Because the housing pot is made of a soft, flexible material that is easily pushed to the side when components are inserted, but deforms elastically due to its flexibility 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 of the housing base and the inserted contact element, are already sealed against dust, water, humidity and / or gases, especially air, even without the additional use of sealants such as adhesives, sealant pastes, sealing rings (e.g., O-rings), etc. Consequently, the receiving system according to the invention...The inventive built-in connector simplifies the creation of a seal against dust, water, humidity and / or gases, especially air, thereby enabling outdoor use, a reduction in the risk of short circuits and / or compliance with certain standards without additional effort. Brief description of the drawings

[0060] The inventive receiving system and the inventive built-in connector are described in more detail below with reference to exemplary embodiments schematically depicted in the figures. Identical elements are marked with the same reference numerals in the figures. The described embodiments are generally not drawn to scale and are not to be understood as limiting. In detail, they show Figs. 1A-1B: Perspective views of an exemplary embodiment of the inventive panel-mount connector, showing an exemplary embodiment of the inventive receiving system in exploded view; Figs. 2A-2B: Perspective views of an exemplary embodiment of the inventive panel-mount connector, showing an exemplary embodiment of the inventive receiving system in the assembled state; Fig. 3: Perspective view of an exemplary embodiment of the inventive panel-mount connector, showing an exemplary embodiment of the inventive receiving system in the assembled state; Fig. 4: Schematic representation of the assembly of an exemplary embodiment of the inventive panel-mount connector on a mounting plate. Detailed description of the drawings

[0061] The Figures 1A and 1Bshow perspective views of an exemplary embodiment of the inventive built-in connector 1 having an exemplary embodiment of the inventive receiving system 2 in 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 inserted at least partially 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 features at the insertion opening 6 the radially extending flange-like projection 10, which is circumscribed by the sealing lip 11, and the recess 13 arranged on the side 12 of the housing pot 3 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 designed to precisely receive the flange 14 of the contact element carrier 7 and extends within the flange-like projection 10 to 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 projection 18 is arranged on the side 17 of the flange-like projection 10 that faces the direction in which the housing pot 3 passes through the support ring 4. The projection 18 is designed to fit precisely into the corresponding recess 19 of the support ring and also extends to the two diagonally opposite corners 15 of the flange-like projection 10, in which the recesses 16 for the passage of the fastening elements are arranged. In the illustrated exemplary embodiment, the projection 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 one part 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 facing in the direction of passage through the support ring 4 (in other words: on the outer side 17 of the housing base 8), a separating element 22 consisting of three partition walls extending from a common point, which separates the parts of the three contact elements 21 that pass through the three openings 20 in the housing base 8 and are located on the outer side 17 of the housing base 8 from each other in such a way that no unplanned contact of the contact elements 21 with other electrically conductive components (e.g. with a wire intended for another contact element) can occur, which could potentially lead to a short circuit.

[0067] The support ring 4 has the mounting flange 23, which has at least approximately the same radial extent as the flange-like projection 10. Therefore, when assembling the exemplary embodiment of the plug-in connector 1 shown, the mounting flange 23 and the flange-like projection 10 lie at least approximately congruently with one another. The support ring 4 also has a cylindrical outer surface 24 that extends axially in the direction in which the housing cup 3 passes through the support ring 4. The inner diameter (or radial extent / dimension) of the support ring outer surface 24 corresponds to the diameter (or radial extent / dimension) of the cylindrical housing cup 3, in particular to the diameter (or radial extent / dimension) of the housing cup 3.the radial extent / dimension) of the cylindrical housing shell 9 is adapted such 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 against 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 inventive plug connector 1 shown, the flange-like projection 10 of the housing pot 3 has a sealing lip 11 circumferential to the flange-like projection 10, wherein the sealing lip 11 - when the flat surface 28 formed by contact element carrier 7 and housing pot 3 is applied to the back of the mounting plate - is pressed against the back of the mounting plate and thus seals the contact area between the flange-like projection 10 and the back of the mounting plate against dust, water, humidity and / or gases, in particular air.

[0069] In the embodiment shown, the support ring 4 has two blind bores 30 arranged diagonally opposite each other on the outer side 29 of the outer surface 24 of the support ring 4, wherein the blind bores 30 are formed at least largely as hollow cylinders open at one end, the respective outer surface of which (the (blind) bores do not necessarily have to have a cylindrical or at least approximately cylindrical outer surface) is formed at least partially by the outer surface 24 of the support ring 4.The blind bores 30 are arranged at two diagonally opposite corners 31 of the mounting flange 23 and are flush with the mounting flange 23 on the side 32 of the support ring 4 which is directed opposite to the direction of passage of the housing pot 3 through the support ring 4, wherein the openings of the blind bores 30 extend within the diagonally opposite corners 31 of the mounting flange 23, wherein the two openings of the blind bores 30 lie in the recess 19 of the mounting flange 23 which extends 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, where no blind hole 30 is arranged, a support structure 34, in particular designed as a triangle, is arranged on the side 17 of the mounting flange 23 facing 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 fasteners are tightly tightened, and thus the desired support effect is ensured even when the receiving system 2 or the plug connector 1 according to the invention is mounted on the back of the mounting plate.

[0071] In the illustrated embodiment, the housing base 8 has three elements 35, each of which is designed as a ridge-like projection (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 engages in each of the cavities formed by the ridge-like projections 35. The counter element 36 is designed as a raised receiving area for receiving the contact element 21 on the contact element carrier 7. The respective ridge-like projection 35 rests against the respective counter element 36, and the contact area formed thereby (in other words, an interference fit) fixes the contact element carrier 7 in the housing pot 3 and is also impermeable to dust, water, humidity, and / or gases, especially air.

[0072] The Figures 2A and 2Bshow perspective views of an exemplary embodiment of the inventive built-in connector 1, comprising an exemplary embodiment of the inventive receiving system 2 in an assembled state. Figure 2AFigure 1 shows 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 inserted into the housing pot 3 to such an extent 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 opposite to the insertion direction 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 plug connector on the mounting plate as the mounting plate-side side), and the flat surface 28 is formed there. This flat surface 28, which is located on the side 12 provided for the installation of the receiving system or the plug connector on the mounting plate,The side of the mounting connector on the mounting plate, which is designed as the mounting plate-side side of the mounting connector, can then be placed against the back of the mounting plate, causing the circumferential sealing lip 11 of the housing cup 3 to rest against the back of the mounting plate. The housing cup 3 also extends through the support ring 4 to such an extent that the flange-like projection 10 of the housing cup 3 abuts the mounting flange 23 of the support ring 4, and the protrusion 18 of the flange-like projection 10 engages precisely in the recess 19 located on the side 32 of the support ring 4 opposite to the direction in which the housing cup 3 passes 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 illustrated exemplary embodiment of the inventive plug connector 1, 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 such that one of the two recesses 38 of the flange 14 of the contact element carrier 7, one of the two recesses 16 of the flange-like projection 10 and one of the two openings of the blind bores 30 of the support ring 4 are approximately congruent with each other, 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 the same.

[0074] If the flat surface 28, in particular with the circumferential sealing lip 11 of the housing cup 3, is now placed against the rear of the mounting plate and a fastening element (e.g., a screw) is inserted from the front of the mounting plate through the mounting plate until the fastening element engages in the blind bore 30, the fastening element 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 element 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 cup 3, is pressed against the rear of the mounting plate.Because the housing pot 3 is made of a soft material, the flange-like projection 10 of the housing pot 3 is pressed against the back of the mounting plate by the contact pressure exerted by the fastening element. This results in a slight compression of the flange-like projection 10 and the sealing lip 11, making the contact surface of the inventive mounting connector 1 with the back of the mounting plate airtight against dust, water, humidity, and / or gases, especially air, even without the use of additional sealing agents 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, particularly around the recesses 16 of the flange-like projection 10, due to overtightening of the fastening element, is prevented, as described above, 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 panel-mount connector 1 is a male panel-mount connector (also referred to as a male panel-mount connector or male device connector). For this purpose, the interior 40 of the contact element carrier 7, designed to receive the cable connector, has the mechanical retention elements 41, which are designed as grooves, and the mechanical locking element 42 provided for the latch of the cable connector-side latch slider. Before the inventive panel-mount connector 1 is fastened, the insertion opening 43 provided for inserting the cable connector into the panel-mount connector 1 is aligned with a corresponding recess in the mounting plate.

[0076] The Figure 3Figure 1 shows a perspective view of an exemplary embodiment of the inventive panel-mount connector 1, including an exemplary embodiment of the inventive receiving system 2 in its assembled state. In this exemplary embodiment, the contact element carrier 7 is designed such that the inventive panel-mount connector 1 is a female panel-mount connector (also referred to as a female panel-mount connector or female device connector). In the female panel-mount connector 1 shown, a support element 52 is arranged in the interior 40 of the contact element carrier, extending from the interior 40 opposite to the insertion direction 12 of the cable connector into the contact element carrier 7. This support element 52 has mechanical retention elements 41 designed as lugs.Among other things, because the contact element carrier interior 40 of the female panel-mount connector 1 must accommodate or contain not only the cable connector but also the support element 52, the contact element carrier 7 of the female panel-mount connector 1 according to the invention has a larger diameter (in other words: a larger radial extent / dimension) than the one in the . Figures 1A to 2BThe contact element carrier 7 of the male panel-mount connector 1 according to the invention is shown. In order for this enlarged contact element carrier 7 to be received by the receiving system 2 according to the invention, the housing cup 3 and the support ring 4 must each also be designed with an enlarged diameter or with an enlarged radial dimension. However, since the panel-mount connector 1 according to the invention is intended to have certain standardized dimensions (with regard to its spatial dimensions, and in particular also with regard to its radial dimensions), e.g., the so-called D-dimension, in the illustrated embodiment the outer surface of the contact element carrier 7, the outer surface of the housing cup 3, and the outer surface 24 of the support ring 4 are not designed with a circular cylindrical shape, as otherwise the radial dimension of the panel-mount connector 1 according to the invention would exceed the desired dimension.Instead, the lateral surfaces of the respective components 3, 4, 7 are flattened on at least one side, in particular on two diametrically opposed sides, such that the radius of the resulting flat surface 51 is reduced (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), thereby limiting the radial extension of the inventive plug connector 1 and thus ensuring that the desired standardized dimension, in particular the D-dimension, is maintained. In other words, the lateral surfaces of the respective components 3, 4, 7 each extend along a secant line through the respective lateral surface on at least one side, so that a flat surface 51 is formed on this side.

[0077] It is generally understood that the terms "cylinder" and "cylindrical" are not limited to circular cylinders, but refer to all types of cylinders, in particular elliptical cylinders or circular cylinders where at least one side is flattened or where at least a portion of the lateral surface has an increased or decreased radius. Furthermore, it is understood that the support ring 4 does not necessarily have to be in the shape of a circular ring. The term support ring also refers to a ring-shaped body, such as, for example, in Figure 3 As shown, at least one part of the circumference deviates from a circular shape or a part of the lateral surface deviates from a circular-cylindrical shape. For example, the support ring 4 can also have the shape of a hexagonal nut or a hollow cuboid.

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

[0079] The Figure 4Figure 1 shows a schematic representation of the assembly of an exemplary embodiment of the inventive panel-mount connector 1 on a mounting plate 53, wherein the receiving system 2, and thus also the assembled panel-mount connector 1, in the illustrated embodiment has the second support ring 54. The second support ring 54 is brought towards the mounting plate 53 from the front such that 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, with recesses extending in two opposite corners of the support flange of the second support ring for the passage of fastening elements.When the illustrated embodiment of the inventive plug connector 1 is properly assembled, the central axis of the housing cup 3, the central axis of the support ring 4, and the central 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 the diameters of the recesses of the support flange of the second support ring 54, the diameters of the recesses 38 of the flange 14 of the contact element carrier 7, the diameters of the openings of the blind bore 30 of the support ring 4, and the diameters of the recesses 16 of the flange-like projection 10 being at least approximately equal. If a fastening element 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 element 55 is also guided through 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, until the fastening element 55 engages in the blind bore 30 and the components 3, 4, 7, 54 are thus drawn together and fastened. Because the illustrated embodiment of the inventive plug connector 1 is supported on the mounting plate 53 from both the front and the rear, and the fastening element 55 passes from front to rear through all of the components 3, 4, 7, 54, the fastening of the plug connector 1 to the mounting plate 53 is reinforced.

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