Definitions

• the invention relates to an electrical connector according to the preamble of claim 1.
• Such plug connectors in the form of device sockets or chassis sockets, are used to connect cable plugs, among other things, to data cables.
• RJ45 connectors represent a large area of application.
• the chassis sockets typically comprise a housing with at least one plug-in opening for at least one cable connector, which housing is built into the wall of an appliance, a panel or the like.
• a projecting connecting flange with recesses for fastening means is arranged on the plug-in end of the housing.
• a flange plate on the insertion side is also provided with an insertion opening for the complementary connector and with mounting holes for connection to a device wall, a control panel or the like.
• the rear of the housing is essentially open and only the contacts that protrude from the rear of the housing are mechanically and electrically shielded by an attached protective cover, although this protective cover does not form any mechanical connection with the contact elements or the entire set of contacts .
• CN 204516967 U discloses a built-in connector in which a substantially flat sealing plate is inserted between the flange plate and the connecting flange on the housing and seals the connection between these two components.
• a seal could also be used between the connecting flange and the housing.
• the seal points a central cutout at the location of the insertion opening of the chassis connector.
• a rubber cap is often present in order to be able to tightly close the insertion opening when it is not plugged in, ie without the complementary plug connector being plugged in.
• a contact carrier which leads out as a separate component and can be inserted into the housing and fixed therein, but which can also be designed as an inner housing section in one piece with the housing. At least parts of a set of contacts are fixed in a defined position in this contact carrier.
• Such a contact set which is Z-shaped in side view, as disclosed for example in CN 206907969 U or EP 2 833 487 A1, usually has a central section with parallel contact elements and with sections adjoining this central section on both sides Insulators, which enclose a further section of the contact elements by the contact elements being encapsulated with plastic and fixed in their mutual position.
• contact elements are preferably guided crossed within the insulating body and the contact elements at one end of the contact set protrude into the insertion opening for contacting a complementary plug connector inserted into the chassis socket.
• Contact sets or similar arrangements of contact elements are intended for built-in connectors in the RJ45 design, which connect through to a similar connector on the rear side, but which are then not tight when not plugged in and as soon as no sealing cap is used or this has been forgotten that water and/or dust can get into the housing.
• chassis sockets with other contact arrangements for example XLR connectors, or proprietary systems such as powerCON ® or speakON ® of the applicant often have a locking element on their rear side opposite the insertion opening, which closes the housing, often with sealing rings, sealing compounds or the like Sealed passage of moisture and dirt from the plug-in opening into the interior of the device or the control panel.
• the closure element has at least one passage for at least one electrical contact element. Due to the under different contact arrangement, the different design of contact carrier and Housing, these solutions for built-in connectors are not suitable for data connections.
• chassis sockets in which a further insertion opening for a data connector is provided on the rear side.
• the contacts of the insertion opening on the front of the chassis socket are soldered into a circuit board, and on the back soldered contacts go into the second, rear insertion opening.
• chassis sockets of this type are very large on the rear side, because the contacts have to be accommodated in a plastic housing which is again encased in a thin metal jacket.
• the object of the present invention was to overcome the disadvantages of the prior art and to create a device that can be flexibly adapted to different requirements with the greatest possible compatibility with existing systems, designs and size specifications.
• connectors for a wide range of applications should be able to be constructed, whereby alternatively or in combination, the depth, i.e. the dimension in the direction of the axis of the insertion opening, and the tightness are required even without an inserted complementary connector.
• the device according to the invention is characterized in that the set of contacts is at least mechanically connected to the closure element and the contact elements at the end of the set of contacts opposite the insertion opening are guided into the closure element or onto the rear side of the closure element.
• This ensures that the connector socket can be provided with a wide variety of connection options on its rear side, for example a circuit board or printed circuit board connected to the contact elements, which in turn is connected to its own connector, to any other electrical lines or electronic circuits, or the like can be.
• the contact elements can also be connected directly to subsequent electrical lines, or can also lead to a further insertion opening, for example, which is oriented in the longitudinal direction or also in the transverse direction to the longitudinal axis of the housing.
• the mechanical connection of the contact set and the closure element allows the closure element to be properly fixed to the housing, thus also improving the tightness of the housing and ultimately increasing the operational reliability of the plug connector.
• the closure element is formed by the base of a housing and the contact elements are guided outwards through lead-through openings in the base and fixed mechanically and sealingly by a press fit in the lead-through openings.
• the bottom can be made in one piece with the housing, making the production is much easier.
• An embodiment with a plastic plate as a closure element is also possible, through which the contacts on the back are led to the outside. Due to the high degree of tightness, safe use of the connector is also possible in exposed environments.
• the closure element is therefore designed as a printed circuit board with an electrical circuit and is inserted or attached in a sealed manner in or on the rear side of the housing.
• the contact elements are soldered to the circuit board. Due to the use of a complete set of contacts with crossed contact elements the connection to the circuit board on the back of the socket is compatible with conventional wiring patterns without any problems and without loss of performance, and complex compensation measures can be avoided.
• the insulators of the contact set preferably enclose an obtuse angle greater than 135 degrees with one another along the course of the contact elements.
• the set of contacts is thus essentially in a stretched form, which leads to the desired overall size.
• the insulators are in the same or in parallel planes, which are also oriented pa rallel to the longitudinal center axis of the housing of the chassis jack.
• the ends of contact elements lying next to one another in the insulating body are bent away from one another perpendicularly to the plane of the insulating body.
• the contact elements are preferably bent according to standardized contacting schemes and then connected to the circuit board, which ensures the highest possible compatibility.
• the closure element is designed as a housing cover with a passage for receiving and mechanically fixing at least one section of the set of contacts.
• any extensions for the contact elements that are routed to the outside through the closure element can be provided on the rear side of the closure element.

• a rear insertion opening then runs parallel thereto, with angles between 90 degrees and 0 degrees being possible with respect to the longitudinal central axis of the housing.
• a set of contacts is used, the insulators of which close to the central, curved section enclose this angle with one another.

• a preferred embodiment of the invention provides that the contact elements in the central section of the Contact set have at least one bend, so that the insulator enclose an angle between 60 and 180 degrees on both sides of the bend. A right angle is preferred.
• one of the two insulating bodies is kept fixed in the middle section of the passage and is aligned parallel to the plane of the closure element, parallel to the plane of the rear peripheral edge of the housing.
• This insulating body is thus at least optimally in contact with the holding and positioning surfaces arranged perpendicular to the longitudinal center axis and insertion direction in the middle section of the passage through the locking element, which ensures the good holding effect and precisely defined positioning of the contact set.
• an optional, advantageous embodiment of the invention is based on this at least part of the central section of the passage is filled with a hardened sealing compound.

It is also important that the locking element is not projected beyond the rear end of the actuating element in any position.

• the casting compound 34 can be introduced directly into the arrangement of the housing cover 21 and the contact set 18 without additional auxiliary seals, without it being able to leak through gaps or clearances between the housing cover 21 and the contact set 18 before it hardens.
• the housing cover 21 itself can - which is particularly important if there is no rear cover 23 as an anchoring point for a mechanical connection by means of the grounding contacts 16 - after insertion or attachment to the rear end face of the housing 1 with the housing be connected mechanically. This can advantageously be accomplished by tightly gluing the housing cover 21 and the housing, by ultrasonic welding or other similar, known connection methods. A screw connection would also be conceivable.
• a sealing ring that may be provided can reinforce the sealing effect or ensure it in the first place. Such a sealing ring can be positioned in a groove in at least the housing cover 21 and/or the housing 1 .

• a set of contacts 18 is used here, the insulating bodies 19 of which adjoin the central, curved section enclose an angle of 135 degrees with one another, as can be seen clearly in the side view in FIG. Since typically the front of the chas- sis socket with the insertion opening 2 and the insulating body 19 with the contacts 17 remains coaxial to the longitudinal center axis M of the housing 1, consequently the rear insertion opening 24 also runs at an angle of 135 degrees to the longitudinal center axis M of the housing 1 and is opposite the rear end face of the Housing 1 and the level of the housing cover 21 is pivoted by 45 degrees, which can be easily seen from FIGS. 15 and 18.

• the middle section 27 runs in the same way as the insertion opening 24 at an angle of 45 degrees to the housing cover 21 level.
• a further embodiment variant of a chassis socket according to the invention has a differently designed closure element, for which a schematic representation together with a set of contacts 18 with two insulating bodies 19 is shown schematically in FIGS. 13 and 14 and for use with a housing 1, contact carrier 15 and any additional modules already described or listed below.
• the closure element is a plastic plate or plastic disk 35, the shape of which is preferably selected to correspond to the cross section of the rear edge of the housing 1, in order to be inserted therein or fixed therein by means of a press fit.
• the dimensions of the plastic plate 35 can also be designed according to the contour of the rear edge of the housing 1 in order to be placed on the rear face of the housing 1 and fixed there, for example by gluing, ultrasonic welding, crimping or screwing.
• the housing 1 could be designed with a rectangular or square cross section, for which the rectangular or square closure elements shown in the form of the plastic discs 35 or the circuit board 36 are then adapted accordingly.
• the peripheral edge of the plastic plate 35 or the entire rear side of the housing 1 can be cast sen with a sealing compound to achieve optimal water and dust tightness.
• the closure element can also be designed in one piece with the housing 1 as its bottom.
• the contacts 20 of the contact set 18 are guided outwards again through the locking element and can be connected there to other connection components, for example to a circuit board 36.
• circuit board 36 could also, as is realized in the embodiment of the invention shown in FIG. 14, itself represent the closure element.
• the above explanations apply analogously to their shape, arrangement and sealing.
• the contact elements 20 of the complete contact set 18 are fixed with at least two insulating bodies 19 adjoining the central middle section 25 in the plastic plate 35 or plastic disc by means of a press fit, sealing against moisture, dust and dirt and are attached to any type of circuit board 36 their pads soldered.
• a complete contact set 18 is used, which in this case is in a stretched configuration.
• the insulating bodies 19 of the contact set 18 enclose an obtuse angle greater than 135 degrees with one another, as is also shown in FIGS. 13 and 14.
• the central section 25 with its preferably straight contact elements between the insulators can be designed in such a way that the insulators 19 are also aligned parallel to one another, whereby they can be arranged in parallel, spaced-apart planes or plane-parallel.
• the use of a complete contact set 18 with two insulators 19 ge also allows a construction in which the ends in the insulator 19 are next to each other of the contact elements 20 - on the opposite side of the insertion opening 2 of the contact set 18 - perpendicular to the plane of the insulator 19 bent away from each other are, so that sufficiently large distances between the soldering points on a circuit board 36 are ensured.
• Compatibility can also be ensured by bending the contacts 20 in such a way that their ends can be connected to the circuit board 36 in accordance with standardized contacting schemes.
• a locking arrangement 37, 38 is also positioned in or on the housing 1, the at least one locking arm 37 of which can also be unlocked again by means of an actuating element 38.
• This actuating element 38 protrudes forward with an operating tab 39 beyond the plug-in end of the housing 1 so that it can be easily reached and actuated by the user.
• the operating tab 39 is preferably perpendicular to the central axis M of the housing 1 and also the longitudinal axis of the actuating element 38 bent up to a transverse to the central axis M of the housing 1 and also the longitudinal axis O of the actuating element 38 Mentes axis.
• the operating tab 39 is preferably covered by a dome 40 which is inserted into the seal 8 or is formed on it.
• a radially outward-pointing recess extends from the insertion opening 2 of the housing 1 and also from the insertion opening 6 of the flange plate 5, through which the actuating element 38 can reach the front side of the flange plate 5 can protrude.
• the elastic locking arm 37 is mounted on the contact carrier 15, preferably in an elongated recess on the upper side, which has at least one locking structure on the side facing away from the central longitudinal axis M of the housing 1, here in the form of two on the outer edge of the flat locking arm 37 , Has nose-shaped locking s in front of cracks 41 in the side view.
• the locking arm 37 engages in the inserted state of a complementary connector inserted into the insertion opening 2 in corresponding complementary locking structures of this connector, preferably in at least one locking recess in a socket-shaped insertion section of this connector.
• the plugged in and locked cable plug is thus secured against being unintentionally or unintentionally pulled out of the plug-in opening 2 .
• they have a start-up bevel in a known manner.
• the actuating element 38 is, starting from a passive position shown in the drawing figures, in which it moves forwards at most over the housing 1 juts out parallel to the longitudinal center axis M of the housing 1 and the contact carrier 15 to the rear into an active position.
• the actuating element 38 is slidably mounted on the contact carrier 15, preferably above the locking arm 37 and preferably in the same recess of the contact carrier 15 as this, in order to ensure optimal guidance of the locking arm 37 and actuating element 38 relative to one another.
• an actuating section 42 on actuating element 38 preferably acts on an inclined surface 43 as the unlocking surface of locking arm 37 and bends it in the direction of central axis M of housing 1 and contact carrier 15, whereby the locking projections 41 are disengaged from the locking structure of the plugged-in connector and thereby release it for pulling out of the plug-in opening 2 . If the actuating element 38 is released again by the user, the spring-elastic locking arm 37 moves back into its initial position, whereby it also pushes the actuating element 38 back into its passive position.
• the operating section 42 is arranged at the extreme rear end of the operating element 38 and is not rearwardly positioned by any other section of the operating element 38, i.e. in the direction of its longitudinal axis O, in the direction of the longitudinal central axis M of the housing 1 and also in the direction of displacement from the passive position in the active position, overhangs. This results in a particularly short overall depth for the chassis bushing with a locking arrangement 37, 38 designed in this way.
• the actuating section 42 is formed by at least one tongue, which rotates about a direction parallel to the longitudinal axis of the actuating element 38 or the longitudinal center axis M of the housing 1 oriented bending axis is bent around.
• the actuating section 42 preferably has a bevel on its rear side. The rear end of the actuating element 38 is also easy to manufacture due to its open shape.
• the inclined surface 43 on the locking arm 37 is preferably arranged in its rear section in order to be able to keep this component short while still having sufficient leverage so as not to use too much force to move the actuating element 38 from the passive position to the active position must. Also for the locking arm 37 It is therefore advantageous that no section of the locking arm 37 protrudes backwards from the oblique surface 43 effective for the unlocking. It is also particularly advantageous if no section of the actuation element 38 protrudes beyond the unlocking surface 43, even if this is maximally displaced into the active position.
• the locking arm 37 could also be pivotally mounted on the contact carrier 15 and acted upon by a separate spring element into the position in which it engages in the locking structure of the complementary connector plugged into the housing 1.
• the housing 1 of the chassis bushing can have an inner length up to the rear closure element, which coincides with the rear end of the locking arm 37 or with the rear end of the actuating element 38 in its maximum active position, in which it is entirely shifted backwards.
