Description

The invention is based on a connector according to the preamble of independent claim 1.

Such connectors are used in the industrial environment and there in particular in harsh environments.

State of the art

the EP 0 945 929 A2 shows a connector with a rectangular cross section for use in an industrial environment. The connector shows an insulating body in which the contact elements with insulation displacement connection technology are arranged. The individual conductors of a connected cable are arranged in a contact piece. When the contact piece and insulating body are brought together, the individual conductors are electrically conductively contacted with the associated contact elements. The insulating body that is brought together with the contact piece is surrounded by a metallic connector housing.

The connector of the EP 0 945 929 A2 has proved its worth. However, due to its many parts, it causes high production and assembly costs. In addition, the parts in the connector housing require a lot of installation space, which makes the connector very large overall and thus limits its field of application.

the U.S. 1,672,521 A shows a connector, the housing of which is made from two parts screwed together. The two parts each have two receptacles for the respective fixation of a contact element.

the GB 1 537 061 A shows a connector, the connector housing of which is molded onto the cable. Contact elements, which are also arranged in the connector housing, are connected to the individual conductors of the cable.

the EP 0 424 699 A2 shows a housing bushing with an insulating body through which a cable is passed.

The D5 US 2004/0235321 A1 shows two plug-in connectors in the housing of which contact elements that match each other are held.

the DE 10 2015 113 786 A1 shows a connector which has a connector housing with a locking bracket, an insulating body arranged in the connector housing and an electrical contact arranged in the insulating body.

In the industrial environment, there is a general need to utilize the available space as well as possible, i.e. to accommodate as many technical components as possible in a limited space. Accordingly, an installation space that is as compact as possible is required for such industrial connectors. At the same time, a wide range of functions is required. The connectors have to perform a wide variety of tasks.

The German Patent and Trademark Office researched the following prior art in the priority application for the present application: U.S. 1,672,521 A , GB 1 537 061 A , EP 0 424 699 A2 , DE 10 2015 113 786 A1 , US 2004/0235321 A1 .

Task

The object of the invention is to make a connector for rough industrial environments as compact as possible and at the same time to provide a wide range of functions.

The object is achieved by the subject matter of independent claim 1.

The connector according to the invention can also be produced particularly inexpensively due to its modularity and the use of the same components in different design variants.

By simply exchanging only individual components, different functionalities can be provided.

Advantageous refinements of the invention are specified in the subclaims.

The connector according to the invention consists of an insulating body and at least one contact element which is fastened or fixed directly in the insulating body. As a rule, the plug connector will have several contact elements, all of which are fastened or fixed in the insulating body. The insulating body is designed in such a way that it simultaneously forms the connector housing of the connector. As a result, the insulating body or the connector housing is designed to be correspondingly robust and aesthetically pleasing on the outside.

The insulating body has a rectangular cross section and essentially has the shape of a cuboid. The outer surfaces are designed to be essentially smooth. Only the necessary functional elements, which for example enable locking with a mating connector, are arranged or molded onto the outer surfaces.

The terms connector and mating connector are sometimes used synonymously in this application. A mating connector only describes a connector that is designed so that it can be plugged into a suitable connector.

The insulating body preferably has a fastening tab or a fastening tongue for reversible fastening with a mating connector. The mating connector can be constructed in a manner comparable to the connector and have essential features in common with it. A common feature could be that the insulating body also forms the connector housing in the mating connector.

The plug connector preferably has an add-on housing for attachment to an electrical device. In this case, the connector forms a so-called device socket on the electrical device. The add-on housing can be straight or angled, depending on the structure and geometry of the device. This makes plugging with a connector to be connected more convenient. Even if the term device socket is used here, both insulators with socket contacts and insulators with pin contacts fit into such an add-on housing.

Alternatively, the plug connector has a strain relief element for strain relief of a plurality of individual conductors connected to the plug connector or of a connected cable, which in turn can comprise a plurality of individual conductors through an outer cable sheath. Such a connector offers strain relief protection for the conductors and / or for the cable and is often used in environments, for example within a control cabinet or a device, in which there is no special protection against media such as water, necessary is. Such a connector can be correspondingly sealed by a seal with passage openings, also called a single-wire sealing seal, which is mentioned below.

Alternatively, the plug connector has a cable housing for fixing and strain relief of a connected cable. Compared to the simply constructed strain relief element, the cable housing offers not only the strain relief function but also improved sealing properties, so that a connector equipped with it is impermeable to media such as water.

A bearing journal is preferably formed on two opposite side surfaces of the insulating body. A locking bracket with a U-shaped cross-section can be pivotably mounted on the bearing pin via lateral bearing receptacles of the locking bracket. The bearing journals advantageously each have a cylindrical basic shape with a prism-shaped contour formed thereon. The prism-shaped contour preferably has a triangular cross section.

In a particularly advantageous embodiment of the connector according to the invention, the locking bracket has an embossing directed towards the connector housing in the area of its bearing receptacles. The embossing of the locking device is supported in the locked state on the contour of the bearing pin. In the unlocked state, the locking device is expanded during the locking process through the interplay of embossing and contour. In the unlocking process, too, the locking device is initially widened when it is pivoted away by the contour. The locking process and the unlocking process can each be carried out with little wear will. As a result, the insulating body is not damaged or scratched by the locking bracket, which means that it can perform its housing function over the long term.

The plug connector preferably has a seal which has through openings for the contact elements and / or the conductors connected to them. The number of through openings corresponds to the number of contact elements that the connector has. This seal is preferably arranged in the insulating body. This enables the connector to be particularly tightly sealed.

In an advantageous embodiment of the invention, the plug connector has contact inserts in which at least one contact element is arranged. The contact carrier is fastened in the insulating body. Such a contact carrier is ideally used when the contact elements are particularly large and / or massive. Such contact elements preferably have a crimp connection or a screw connection for making electrical contact with a conductor. The contact carrier ensures that such contact elements are firmly seated in the insulating body.

In a particularly preferred embodiment of the invention, the connector has a shield plate. The shield plate is essentially flat and aligned within the insulating body parallel to the plug-in direction. On the connection side, the shield plate can be connected in an electrically conductive manner to a braided shield of the connected cable. On the plug-in side, the shield plate preferably has two tabs which point in the plug-in direction and are arranged offset to one another. If a connector having a shield plate is plugged into a corresponding mating connector, the tabs of the connector grip on the opposite tabs of the mating connector so that the screen is reliably transferred.

In an advantageous variant of the invention, the plug connector has a shielding sleeve which is arranged inside the insulating body. The shielding sleeve is used for electromagnetic shielding of the contact elements arranged in the connector. Such a connector transmits data or signals with a particularly high signal integrity.

The plug connector preferably has at least one identification element. The identification element can, for example, be clipped onto the outside of the insulating body, that is to say fixed reversibly. The identification element is available in several colors and in each case has a different color from the insulating body. As a rule, the insulating body is colored black. The identification elements can be designed in a correspondingly colored manner and, in particular, have so-called signal colors applied to them. If there are several plug connectors according to the invention on an electrical device, they can be easily distinguished from one another using differently colored identification elements, which, for example, simplifies the maintenance of such an electrical device.

The figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for identical, but possibly not identical elements. Different views the same elements could be scaled differently.

The invention relates to a connector 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII , essentially consisting of an insulating body 2, 2 'and at least one contact element 4, 4', 4 ", 4"", 4 ^IV , 4 ^V , 4 ^VII , 4 ^VII , which is fastened or held in the insulating body 2, 2 ', the insulating body 2, 2' being the connector housing of the connector 1, 1 ', 1" , 1 "", 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII forms. The connector 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII is not, however, on this Components limited. In the following figures, various embodiments of such a connector 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^{VII are} presented. The connector 1, 1 ', 1 ", 1"' , 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII has a particularly simple structure and can therefore be assembled quickly. In addition, the connector 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^{VII is} very robust and suitable for industrial use, especially in harsh environments.

In Figure 1 an exploded view of a connector 1 designed according to the invention can be seen. The connector 1 consists of an insulating body 2, an add-on housing 3, 3 'and one or more contact elements 4. The add-on housing 3, 3' can, as in FIG Figure 1 to see straight ( Figure 1 , top left) or angled by about 90 ° ( Figure 1 , bottom left). The add-on housing 3, 3 'has recesses (not shown) which, for fixing purposes, engage via locking webs 30 which are provided for this purpose and are molded onto the insulating body 2, 2'. This fixation works analogously to the strain relief element 28, which is described below, and underlines the modularity of the connector according to the invention. A cylindrical bearing receptacle 5 is formed on each of two side surfaces of the insulating body 2. A prism-shaped contour 9 is formed directly on the bearing receptacle 5, the function of which is described in more detail below.

The plug connector 1 'or mating plug connector 1' (terms are used synonymously) optionally has a cable housing 13 for fixing and strain relief of a connected cable (not shown). For this purpose, the cable housing 13 is equipped with a cable screw connection 14 and an associated seal 15. The media tightness of the connector 1 'is increased by the cable housing 13.

The connector 1 can optionally be equipped with a locking bracket 6. The locking bracket 6 consists of a sheet metal which has been processed in a stamping and bending process. The locking bracket 6 has an essentially U-shaped basic shape. In the side flanks of the locking bracket 6, bearing receptacles 7 are introduced, which overlap over the bearing journals 5 of the insulating body 2. As a result, the locking bracket 6 is pivotably mounted on the insulating body 2. Bearing pins 5 are also formed on a mating connector 1 '. In the locked state, the locking bracket 6 engages over the bearing pin 5 of the mating connector 1 '. As a result, the connector 1 and the mating connector 1 are reversibly locked to one another.

A prism-shaped contour 9 is also formed on the bearing pin 5 of the mating connector 1 '. The bearing journals 5 are made longer than the respective contour 9. This means that the bearing journals 5 protrude vertically further from the insulating body 2, 2 ′ than the respective contour 9.

The locking bracket 6 has an inwardly directed embossing 8 in the area of its bearing receptacles 7. With the help of the embossments 8 and the contours 9 formed on the bearing pin 5, the locking device 6 is elastically expanded during the locking process. The locking device 6 does not rub with its side parts on the insulating body 2, 2 'or on its side surfaces.

Due to the shape of the contours 9 and the associated embossments 8, the locking bracket 6 is held in its position in the locked state. During the unlocking process, a resistance must be overcome, since the locking bracket 6 is again elastically widened. In this way, accidental opening of the system or the plug connection comprising plug connector 1 and mating plug connector 1 'is ruled out. In addition, the locking bracket 6 does not rub with its side parts on the insulating body 2, 2 ', neither on the insulating body 2 to which it is pivotably attached, nor on the insulating body 2' of the mating connector 1 'to be connected.

The plug connector 1, 1 ′ has a seal 10. The seal 10 is in Figure 14 shown enlarged. The seal 10 has a substantially rectangular cross section, the corners or corner regions being rounded. The seal 10 has a lamellar structure 11 on the narrow sides. The seal 10 has six through openings 12. The through openings each enclose a conductor (not shown) which is connected to an associated contact element 4; 4 'is attached and electrically contacted. As a result, the media tightness of the connector 1, 1 'is significantly increased. The number of through openings 12 corresponds to the number of contact elements 4, 4 'arranged in the plug connector 1, 1'.

In the Figures 3 and 4 an alternative (second) embodiment of a connector 1 ″, 1 ″ ″ according to the invention is shown. The insulating body 2, 2 ′ is designed essentially identical to the previous embodiments. The insulating body 2 'of the mating connector 1''' has a matching fastening tongue 17 with a latching hook 18. The insulating body 2, 2 'is made of plastic. The on the insulating body 2 'des Mating connector 1 ', 1''' molded fastening tongue 17 is designed to be elastic. During the plugging process, the fastening tongue 17 of the mating connector 1 '''engages in the fastening tab 16 of the connector 1 "and the latching hook 18 engages an undercut (not shown for illustrative reasons) of the fastening tab 16. As a result, the connector 1, 1" and the mating connectors 1 ', 1''' are reversibly locked with one another. Insulating bodies can also be provided without these molded-on latching means, which are then limited to the locking bracket 6 described above.

The second embodiment of the plug connector 1 ″, 1 ″ ″ according to the invention has a contact carrier 19. The contact carrier 19 contains receptacles 20 in each of which a contact element 4 ″, 4 ″ ″ is arranged. The contact carrier 19 is latched in the insulating body 2, 2 'of the connector 1 ", 1"'. The contact elements 4 ", 4"'in the insulating body 2, 2' of the connector 1 ", 1 '". The contact elements 4", 4 "' have a screw connection on the connection side. The strands of a connected conductor (not shown) are fastened in a receptacle sleeve on the connection side by means of a screw on the side. The screw connection technology ensures easy assembly of the connector 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VI . Such contact elements 4 ", 4"'are used in particular for the transmission of high currents.

In Figure 5 said contact carrier 19 is shown in perspective. To fix the contact carrier 19 in the insulating body 2, 2 ', a fastening tab 21 is formed on the contact carrier 19, which contains a recess 22 that overlaps a corresponding molding (not visible for reasons of illustration) in the interior of the insulating body 2, 2'. The contact carrier 19 forms the so-called in the insulating body 2 Plug-in area, provided this is equipped with pin contacts 4 ". The contact elements 4", 4 "'are only enclosed and held by the contact carrier 19. The insulating body 2 does not support this function. This allows the connector 1 ", 1"'' to be made more compact.

In the Figures 6 and 7 an alternative (third) embodiment of a connector 1 ^IV , 1 ^V according to the invention is shown. The connector 1 ^IV , 1 ^V has contact elements 4 ^IV , 4 ^V , which can be fixed or fixed directly in the insulating body 2, 2 '. The connector 1 ^IV , 1 ^V has a shield plate 23 which is arranged in the insulating body. On the connection side, the shield plate 23 has a U-shaped braided shield receptacle 24 which can be connected in an electrically conductive manner to a braided shield of a connected cable (not shown). The braided shield receptacle 24 is pressed around the stripped braided shield of a connected cable and thereby connected to the shield plate 23 in an electrically conductive manner. This connection can be supported by a cable tie.

In Figure 8 the shield plate 23 is shown separately. The shield plate 23 consists of a metallic sheet and has been produced in a stamping and bending process. On the plug-in side, the shield plate 23 has two tabs 25 which point in the plug-in direction and are offset from one another. When the connector 1 ^IV and ^{mating connector 1 V are} plugged together, the tabs 25, 25 'of the respective shield plates 23 interlock, as in FIG Figure 9 you can see. This brings the braided shields of the ^{cables connected to connector 1 IV} and mating ^{connector 1 V} to the same electrical potential.

In the Figures 10 and 11 an alternative (fourth) embodiment of a connector 1 ^VI , 1 ^VII according to the invention is shown. The connector 1 ^VI , 1 ^VII comprises contact elements 4 ^VI , 4 ^VI . the Contact elements 4 ^VI , 4 ^VII are held in the insulating body 2, 2 'via a two-part contact carrier 19'a, 19'b or via a three-part contact carrier 19a, 19b, 19c. The contact ^{elements 4 VI} , 4 ^VII are designed for the transmission of large amounts of data or amounts of signals in a high frequency range. For electromagnetic shielding of the contact ^{elements 4 VI} , 4 ^VII , the plug connector 1 ^VI , 1 ^VII has a shielding sleeve 26 which is arranged within the insulating body 2, 2 '. The shielding sleeve 26 is formed from an electrically conductive material and has contact arms 27 on the connection side, which can be connected in an electrically conductive manner to the braided shield of a connected cable (not shown). This connection can be supported by a cable tie. Due to the shielding sleeve 26, the connector 1 ^VI , 1 ^VII offers particularly good signal integrity.

In Figure 12 a strain relief element 28 already mentioned above can be seen. The strain relief element 28 is provided for strain relief of several conductors (not shown) or a connected cable (not shown). The strain relief element 28 has a rectangular cross section and can be plugged onto the connection side of the insulating body 2, 2 'and fastened in a latching manner. The strain relief element 28 has recesses 29 which engage via locking webs 30 provided for this purpose and molded onto the insulating body 2, 2 '. On the connection side, the strain relief element 28 has a support web 31. The individual connected conductors or the cable sheath of the connected cable can be placed on the support web 31. The conductors or the cable can then be fixed on the support web 31 with the aid of a cable tie 32. This provides a very inexpensive but nevertheless extremely effective strain relief for the conductor and / or the cable.

The connector 1 according to the invention can be equipped with an identification element 33, as shown in FIG Figure 13 is shown. To fix the identification element 33 on the insulating body 2, 2 ', the identification element 33 has a gripping hook 35 at each end, each of which engages a recess 34 on both sides in the insulating body 2, 2'. The identification element 33 has a color different from the insulating body 2, 2 ', in particular a signal color such as yellow or red or a combination of different signal colors. The identification element 33 can be used, for example, to be able to distinguish several similar plug connectors 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII on an electrical device from one another.

In Figure 15 a perspective view of a wall bracket 36 can be seen. The wall bracket 36 can be attached to a device wall, for example. For this purpose, the wall mounting has openings 37 into which screws (not shown) can engage for fastening. The wall bracket 36 has a rectangular, flat basic shape. S-shaped fixing arms 38 protrude perpendicularly from the corner areas of the basic shape. With the aid of these fixing arms 38, a plug connector (1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII ) according to the invention can be reversibly fixed to the wall bracket 36. The plug connector ( 1, 1 ', 1 ", 1"', 1 ^IV , 1 ^V , 1 ^VII , 1 ^VII ) can be fixed to a device wall, for example. Several wall brackets 36 can be strung together via lateral contours 41. This enables particularly clear device installations.

In the Figure 16 shows an alternative (fifth) embodiment of a connector 1 ^VIII according to the invention. The insulating body 2, 2 'is designed essentially identically to the previous embodiments. The fifth embodiment of the connector 1 ^VIII according to the invention has a holding plate 39. The holding plate 39 contains receptacles 40, in each of which a contact element 4 ^{VIII is} arranged. ^{The holding plate 39 is latched in the insulating body 2, 2 'of the connector 1 ", 1"'. The contact elements 4 VIII} are then ultimately also attached to the insulating body 2, 2 'of the plug-in connector 1 ", 1"' via the holding plate 39. The contact elements 4 ^VIII have a crimp connection on the connection side. In contrast to the variant with the contact carrier ( Figures 3 and 4 ) the retaining plate 39 does not form the plug-in area of the connector 1 ^VIII .

Even if various aspects or features of the invention are each shown in combination in the figures, it is clear to the person skilled in the art - unless stated otherwise - that the combinations shown and discussed are not the only possible ones. In particular, corresponding units or feature complexes from different exemplary embodiments can be exchanged with one another.
