(Fig. 3)

Description

The invention relates to a socket for a combined electrical connection and data connection between a motor vehicle and a vehicle component such as a vehicle trailer or a vehicle-mounted machine or the like of a passenger car, truck, agricultural vehicle or other commercial vehicle. The socket should be suitable for mounting in the outside area of the motor vehicle, which requires a mechanically correspondingly robust structure, which must also be specially sealed. Especially when data is being transmitted, effects caused by moisture, for example changes in capacity in the area of the contacts, can lead to disruptions in data communication.

A socket proposed according to the invention has in particular the following components

• a housing with an insertion opening for connection to a plug of the vehicle component (for example a trailer or the machine of a commercial vehicle) and a cover which seals the insertion opening when not in use, ie when no plug of a vehicle component is plugged into the socket;
• a contact carrier with contacts fixed in the contact carrier for an electrical connection (e.g. for supplying the vehicle component with a supply voltage) and with a data connector fixed in the contact carrier, the contacts for the electrical connection and the data connector being accessible from the insertion opening, see above that an electrical connection or a data connection to a plug of the vehicle component inserted into the insertion opening can be or will be established; and
• one of the plug-in opening with reference to the contact carrier in particular opposite and referred to as the rear connection space of the socket for connecting the electrical contacts and the data connector to an electrical network and a data network of the vehicle.

When integrating a data connector in a pin pattern with conventional contacts, there are often problems with the tightness of the connector and the shielding of the data transmission from electrical interference.

The object of the invention is therefore to create a socket with data contacts and conventional electrical contacts that meet high tightness requirements, enable secure data transmission and allow the plug to be easily inserted into the socket.

This object is achieved by a plug having the features of claim 1. For this purpose, in the case of a socket of the type mentioned at the outset, it is provided in particular that the data connector has at least one electrically conductive, in particular a metallic, outer socket for electrically shielding the data transmission in the data connector, at least one data contact for establishing the data connection and one in the (or more) outer socket - Each) outer socket has a carrier body made of an insulating material for receiving the at least one data contact, the data contact or the preferably several data contacts being fixed in a sealing manner in the carrier body by pressing in or overmolding, and the carrier body being fixed in a sealing manner in the outer socket by pressing or injection. An electrically and magnetically acting shield is particularly preferred.

According to the invention, according to a particularly preferred embodiment, a common shield can be provided for all data contacts, which are all fixed together in the carrier body. The carrier body is accommodated in the outer socket in a reliably sealed manner. This avoids that, in the case of several data contacts, several shields have to be accommodated in a sealing manner in the socket housing and that each carrier body has to be reliably sealed again in each shield. However, there are also applications in which certain data lines and data contacts should be shielded separately from other data lines and data contacts. In this case, individual data contacts or groups of data contacts can, according to the invention, also be surrounded by their own shielding and received in the contact carrier of the socket. The shielding with the enclosed data contacts then acts in principle as a separate shielded data connector, so that interference from other data transmissions is very reliably shielded. According to the invention, a plurality of such data plugs can then be provided in a socket.

Within the scope of the invention it can also be provided that certain control voltages or control currents are also transmitted via the data contacts, for example if a shielded connection is to be provided for an application that requires the transmission of data and control signals. According to the invention, a low-voltage supply voltage can also be made available via data contacts, for example for electronic circuits with low power requirements. It is also possible to additionally transmit the ground on the shielding via a data contact.

The data contacts in the data plug connector can in particular be pin contacts and / or socket contacts made of electrically conductive material, which produce an electrically conductive connection with the respective corresponding mating contacts. Pin and socket contacts have particularly large contact areas and thus achieve the smallest possible contact resistance. This improves the quality of the data transmission.

• Polyetheretherketon (PEEK), ε_R ≈ 3,2
• Teflon, ε_R ≈ 2,5
• Polyethylen (PE), ε_R ≈ 2,3
• Polyethylen hoher Dichte (PE-HD)), ε_R ≈ 2,4

A material with a low dielectric constant ε _{R is} suitable as the insulation material for the carrier body. Examples of suitable materials are:

• Polyetheretherketone (PEEK), ε _R ≈ 3.2
• Teflon, ε _R ≈ 2.5
• Polyethylene (PE), ε _R ≈ 2.3
• High density polyethylene (PE-HD), ε _R ≈ 2.4

Material with a low dielectric constant ε _R within the meaning of the invention is in particular a material with a dielectric constant of approximately ε _R <3.5, preferably of approximately ε _R <3.0 and particularly preferably of approximately ε _R 2.5.

Since both the at least one data contact is sealingly received and fixed in the carrier body and the carrier body is sealingly received and fixed in the outer socket according to the invention, the connection areas of the data plug formed on both sides of the carrier body are reliably sealed. Via the plug-in opening, which is possibly exposed to the ingress of moisture at least when a plug of the vehicle component is plugged in, moisture cannot penetrate through the data connector into the data network of the vehicle. The solution proposed according to the invention meets the standards ISO 4019, LV 214, USCAR 2, SAE and combines in a common plug connection common electrical contacts for voltage and power supply and for the direct switching of electrical components (lights, machines, etc.) a data transmission that is used to transmit all types of sensor information, including images from digital cameras that are to be displayed to the driver and transmitted via the socket in a data transmission.

According to a preferred embodiment of the invention it can be provided that the electrical contacts and the at least one data contact, and preferably all data contacts of a total of several data contacts, are designed as axially straight contacts (e.g. pin or socket contacts) that extend from the rear connection space extend straight into the insertion opening. Their ends can be connected directly to the vehicle network, e.g. a vehicle-side connector, and to the connector of the vehicle component, without a complex geometry, in particular of the data contacts and / or an interposed circuit board, being able to impair the quality of the data transmission. According to the invention, the proposed socket therefore preferably does not have a circuit board on which the contacts are fixed and possibly connected to one another via conductor tracks and / or interposed electronic components that each extend into the rear connection space and the insertion opening. This promotes a high quality of data transmission.

A particularly preferred embodiment of the proposed socket provides that the outer socket of the data connector is received in a sleeve of the contact carrier which rests against the outer circumference of the outer socket, ie surrounds it in a form-fitting manner. It can be provided that the outer sleeve extends in its axial direction over at least about a third or half of the length of the outer sleeve. Because the outer circumference of the outer socket rests on the inner circumference of a sleeve of the contact carrier, the outer socket can not only be securely fixed in the contact carrier, but a particularly good seal is also achieved. The sleeve preferably even extends in the axial direction of the outer sleeve over at least three quarters of the length of the outer sleeve. In a particularly preferred embodiment, the sleeve extends in the axial direction of the outer sleeve over the entire length of the outer sleeve. The longer the sleeve, the better the guidance when inserting the plug into the socket.

In a further development of this embodiment, it can be provided that at the end of the sleeve located in the insertion opening an inwardly protruding, i.e. the opening cross-section of the sleeve reducing, collar is formed. This collar makes it possible, for example, to push the outer socket of the data connector from the rear connection space into the sleeve of the contact carrier until it hits the collar. As a result, the outer socket or the entire data connector is fixed in a defined manner in the contact carrier. In addition, the end of the outer socket protruding into the insertion opening is protected from mechanical damage by the sleeve. Such damage can possibly make it more difficult to insert the plug of the vehicle component, damage the seal due to the force acting and / or impair the quality of the data transmission.

The above description can apply accordingly to the electrical contacts, i.e. the electrical contacts or a part thereof can also be arranged and positioned in corresponding sleeves of the contact carrier. This also applies to the following variants of the fixing and sealing, which will again be described with reference to the outer shell of the data connector and can also apply in accordance with the invention to the electrical contacts in the same or correspondingly similar manner.

To fix and seal the data connector, an outwardly protruding mandrel profile can be formed on the outer circumference of the outer socket, which is pressed into the inner wall of the sleeve of the contact carrier when the outer socket is pressed in. This mandrel profile has two effects that are desirable according to the invention: On the one hand, the outer bushing is securely fixed in the sleeve by pressing in the mandrels of the mandrel profile. By compressing the material of the sleeve, it is in this area with special pressure on the outer sleeve and thus achieves a reliable seal.

The housing and the contact carrier of the socket are preferably made from a suitable plastic material, for example in an injection molding process, for example from polyamide, such as reinforced or unreinforced PA 6 or PA 6.6, polybutylene terephthalate (PBT), polypropylene (PP), polyoxymethylene (POM) or other suitable plastics. Such plastic material is particularly suitable for the measures described above. In a preferred embodiment, the housing and contact carrier insert are manufactured in one piece in one injection molding step. This avoids additional contact surfaces between housing parts that would have to be sealed. However, the invention can also be used in sockets in which the socket housing and the contact carrier are constructed in several parts and the contact carrier is inserted into the housing as an insert in a sealing manner and is or is fixed there.

The mandrel profile can have a plurality of mandrels spaced apart in the axial direction on the outer circumference of the outer sleeve. A mandrel can be formed, for example, by a triangular projection of the outer bushing that runs around the outer circumference. Particularly preferred is a shape in which the mandrel protrudes and opens on the side facing the rear connection space exactly or essentially perpendicularly from the outer circumference, for example at an angle between 80 ° or 100 ° or between 85 ° or 95 ° the side facing away from the rear connection space connects again to the outer circumference at an angle of less than 80 ° or greater than 100 °. Angles smaller than 45 ° or larger than 135 ° are preferred. This facilitates the insertion of the outer socket into the sleeve from the rear connection space and makes it more difficult to push it out in the opposite direction.

The mandrels can also be formed by rectangular projections which project symmetrically, preferably at right angles, from the respective wall. One Such or a similar, for example, formed from rectangular grooves, mandrel profile is also suitable if it is overmolded in an injection molding process and not pushed into a sleeve. During injection molding, the injected plastic material wraps itself around the mandrels of the mandrel profile (or penetrates into the grooves of the mandrel profile, and ensures both an axial fixation and a reliable seal.

The mandrel profile can have one, two or more mandrels (or grooves), preferably about one to three.

According to the invention, the outer socket of the data connector and the sleeve of the contact carrier each preferably have a round cross-section with which the same sealing effect can be achieved over the entire outer circumference. The same applies, if necessary, to the electrical contacts and the sleeves of the contact carrier assigned to them.

In an alternative embodiment, the outer socket of the contact carrier insert and possibly the electrical contacts can also be overmolded directly in an injection molding process when the housing of the socket outlet is being formed. In this case too, a thorn profile leads to better fixation. The direct encapsulation of the outer socket of the data connector and / or the contacts also leads to a high level of tightness.

In order to meet the high demands on the tightness of the socket, in particular also in the area of the data plug, according to the invention, a sealing receptacle of the carrier body made of insulation material in the outer socket is also provided.

According to a preferred embodiment, an inwardly protruding mandrel profile can be formed on the inner circumference of the outer bushing when the carrier body is pressed into the outer bushing, it is pressed into the outer wall of the carrier body. In this way, too, secure fixation and a high level of tightness between the carrier body and the outer bushing are achieved.

The mandrel profile can have one or more mandrels, preferably about one to three, spaced apart in the axial direction on the inner circumference of the outer sleeve. A mandrel can be formed, for example, by a triangular projection of the outer bushing that runs around the inner circumference. Particularly preferred is a shape in which the mandrel protrudes and opens on the side facing the rear connection space exactly or essentially perpendicularly from the inner circumference, for example at an angle between 80 ° or 100 ° or between 85 ° or 95 ° the side facing away from the rear connection space connects again to the inner circumference at an angle of less than 80 ° or greater than 100 °. Angles smaller than 45 ° or larger than 135 ° are preferred. This makes it easier for the carrier body to be pushed into the outer socket from the rear connection space and makes it more difficult to push it out in the opposite direction. The mandrels can also be formed by rectangular projections which project symmetrically, preferably at right angles, from the respective wall.

According to the invention, the outer socket of the data plug connector and the carrier body preferably each have a round cross section, with which a uniform sealing effect can be achieved over the entire outer circumference.

Alternatively or in addition, it can be provided that a seal is provided on the outer wall of the carrier body, for example in a sealing groove running around the outer circumference of the carrier body, which seal is supported on the inner wall of the outer bushing when the carrier body is received in the outer bushing. According to the invention, such a seal is particularly useful in embodiments in which the carrier body is inserted into the outer bushing by pressing and is fixed there in a sealing manner.

The seal can be formed, for example, by a sealing ring, such as an O-ring seal. A particular advantage of the seal (compressed during sealing) is that it is suitable for compensating for different expansion behavior of the outer bushing and the carrier body, which typically consist of different materials, such as metal and an insulation material. In the case of a specified application range of the socket proposed according to the invention between -40 ° C to + 85 ° C, different expansion behavior of the outer socket and support body at certain temperatures can result in a seal that is reliable in other temperature ranges no longer working properly due to fluctuations in size. It has been shown that such fluctuations in size can be compensated for by providing an additional seal (or several additional seals) and the tightness can be reliably established.

In such an embodiment, it can be advantageous if several seals, in particular two or three seals, axially spaced from one another, are provided on the outer wall of the carrier body. A seal with several sealing lips can also be provided. This offers redundancy in the sealing if a seal or a sealing surface on the inner wall of the outer socket and / or on the outer wall of the carrier body, for example in the groove provided there, has damage, such as scratches, which impair the tightness.

According to the invention, a flange-like projection can be provided on the inner wall of the outer socket, which projection reduces the free inner diameter of the outer socket in the area of the projection. This projection limits the insertion path of a body inserted into the outer socket. When the support body is mounted from one side, for example from the rear The side facing the connection space, into which the outer socket is pushed until the carrier body abuts the projection, thereby defines its position. When a plug is inserted from the other side, the projection limits the insertion path and prevents a force (for example, the sealing effect impairing) from being exerted on the carrier body by displacing it in the outer socket. When plugged in, the plug hits this flange-like projection and thus prevents any force from acting on the carrier body.

Instead of pushing the carrier body into the outer bushing and pressing it in, the carrier body can also be cast into the outer bushing.

In order to also accommodate the individual data contacts in the data connector in a reliably sealing manner, an outwardly protruding spine profile can be formed on the outer circumference of the at least one data contact (or all data contacts), which when the data contact is pressed into a through opening of the carrier body into an inner wall of the through opening depresses. Reliable sealing and fixing of the data contact in the carrier body is achieved in this way in the manner already described above.

According to a preferred embodiment according to the invention, all of the data contacts provided in the socket are arranged together in a common external socket. This is particularly space-saving and allows a large number of electrical contacts and data contacts to be accommodated in the socket. In addition, only one outer socket has to be sealed in the contact carrier of the socket outlet. This is simpler and cheaper to manufacture and reduces the likelihood of a leak, because basically at every connection surface between the contact carrier and a connector (e.g. an electrical contact or a data connector) leaks can occur. This measure proposed according to the invention significantly reduces the number of connection surfaces. However, sockets with more than one external socket for shielding the data contacts also belong to the subject matter of the invention, as already explained at the beginning.

In a socket according to the invention, between two to ten data contacts can preferably be provided. In principle, however, sockets with a data contact in the carrier body surrounded by an outer socket, similar to a coaxial contact, also fall within the subject matter of the invention. The same applies to more than ten data contacts.

For a common bus system for data transmission, two data contacts are sufficient, with one data contact (preferably the bus ground) possibly also through the electrically conductive, i.e. metallic, outer socket can be replaced. In this case, an additional data contact (in addition to the external socket) is sufficient for data transmission. In a preferred embodiment for a bus system, two data contacts can be provided. According to the invention, for example, even an Ethernet connection can be implemented via eight data contacts, which usually provides for cabling with 4 twisted wire pairs. Depending on requirements, the person skilled in the art can suitably adapt the number of data contacts, for example in order to surround each of the twisted wire pairs of an Ethernet line with an electrically separate (separate) shield.

In preferred embodiments, about two to eight electrical contacts can be provided in the socket, which are arranged around the data connector. In the case of a round plug-in pattern, ie a round or even rotationally symmetrical arrangement of the contacts and the data connector, it is preferably provided that the data plug connector - possibly with only one outer socket - is arranged axially relative to the round plug-in pattern and the rest electrical contacts are arranged offset radially outward around the outer socket (s) of the connector. This has the advantage that the data lines from the socket and the plug can essentially be straight. Kinks in the data lines could impair the transmission quality.

According to the invention, the electrical contacts can be provided to transmit a supply voltage from the motor vehicle to the motor vehicle component. This will often be a DC voltage using two contacts. For example, currents of up to 10A can be permitted via the supply voltage. If, for example, machines or similar systems of the vehicle components are required to operate, it makes sense to provide electrical contacts that are designed for higher currents, for example currents of 25A or 60A.

In order to be able to mount the socket easily, it can be provided that the rear connection space of the socket has a connection opening into which a vehicle-side connector can be inserted for connecting the socket to the vehicle network. This makes it easier to connect the socket to the vehicle network and to replace the socket in the event of a defect. A direct connection of connecting lines of the vehicle wiring harness to contacts in the socket is avoided.

In Figure 1 shows a socket 1 according to the invention for a combined electrical connection and data connection between a motor vehicle and, for example, a trailer as a vehicle component. The socket 1 has a housing 2 with an insertion opening 3 into which a plug 4 of the vehicle component (trailer) can be inserted. A cover 5 is hinged to the housing 2 of the socket 1, which cover closes the insertion opening 3 in a sealing manner when not in use, the cover 5 being pretensioned in the closing direction by means of a spring 6.

Axially opposite the plug-in opening 3, a connection space 7 with a connection opening 8 is provided in the socket 1. In the connection opening 8, a connector 9 on the vehicle side can be inserted for connecting the socket 1 to the vehicle network (electrical supply and data network). The connection plug-in diagram 10 of the connection plug 9 is suitably adapted to the arrangement of the contacts in the connection space 7 of the socket 1, which will be described in greater detail below. To secure the connector 9 to the housing 2, a latching projection 11 is provided on the housing 2, which interacts with a latching device 12 of the connector 9.

Figure 2 shows a plan view into the insertion opening 3 of the housing 2 of the socket 1. Two fastening flanges 13 are formed on the sides of the housing 2. The bottom of the insertion opening 3 is formed by a contact carrier 20 which is provided between the insertion opening 3 and the connection space 7 in the socket outlet 1.

Contacts 30 for an electrical connection and a data connector 40 are defined in the contact carrier 20. The data connector 40 is arranged axially in the center of the insertion opening 3 and comprises several, in the example shown, five data contacts 41 and a common outer socket 42 for electrical shielding of the data transmission in the data connector 40. The electrical contacts 30 for the electrical connection are seen radially outside the outer bushing 42, in the example shown on a circle provided coaxially with the outer bushing 42. In the example shown here, eight electrical contacts 30 are provided

The contact carrier 20 with the contacts 30 for the electrical connection and the data connector 40 are described below with reference to FIG Figures 3 to 7 described in more detail in different variants of the invention.

Figure 3 shows the socket 1 with the cover 5 closed and the housing 2 shown in section. In the housing 2, the insertion opening 3 and the To see connection space 7 with the connection opening 8, which are separated from one another by the contact carrier 20 and sealed against one another. The contact carrier 20 is made in one piece with the housing 2, for example in an injection molding process.

The electrical contacts 30 and the data connector 40 are fixed in the contact carrier 20.

The contacts 30 have a socket section 31 and a pin section 32. The socket section 31 is accessible from the insertion opening 3. The pin section 32 is accessible from the connection space 7. At the end of the socket section 31 facing the pin section 32, a mandrel profile 33 is provided, with which the contact 30 is pressed into a sleeve 21 of the contact carrier 20. As a result, the electrical contact 30 is securely fixed in the sleeve 21. Because the mandrel profile 33 is pressed into the inner wall of the sleeve 21, a reliable seal is achieved in addition to the fixation.

The electrical contact 30 is plugged into the sleeve 21 from the rear end of the socket 1 from the connection space 7. At the end of the sleeve 21 facing the insertion opening 3, the latter has a collar 22 which narrows the inner diameter of the sleeve 21 and thus offers a stop for the contact 30 inserted into the sleeve 21.

In a similar way, the outer socket 42 of the data connector 40 is received in a sleeve 23 of the contact carrier 20 for the outer socket 42. Similar to the sleeve 21, the sleeve 23 also has a collar 24 which protrudes inward at the end of the sleeve 23 located in the insertion opening 3 and narrows the opening cross section of the sleeve 23. When inserting the outer socket 42 of the data connector 40, one end of the outer socket 42 abuts against the collar 24 and thus fixes the data connector 40 or its outer socket 42 in the intended position.

The outer bushing 42 also has an outwardly protruding mandrel profile 43 that is indented into the inner wall of the sleeve 23 and fixes the outer bushing 42 in the sleeve 23 in a sealing manner. The outer socket 42 is also pushed into the sleeve 23 from the rear end of the socket in the connection space 7 and sleeve 23 is pressed in at the same time.

The data contacts 41 each have a pin section 44 at their opposite axial ends. One of the pin sections 44 extends into the connection space 7. The other of the pin sections 44 extends into the plug-in opening 3. The opposing pin sections 44 of the data contacts 41 are connected by a contact body 45 On the contact body 45 - comparable to the spine profile 33 of the electrical contacts 30 - a spine profile 46 is formed, with which the data contacts 41 are held in openings of a carrier body 47 made of insulation material. The data contacts 41, similar to the electrical contacts 30, are pressed into the carrier body 47 in a sealing manner from the rear connection space 7 and fixed.

In order to also fix the carrier body 47 in a sealing manner in the outer bushing 42, an inwardly protruding mandrel profile 48 of the outer bushing 42 is provided - approximately in the axial center of the outer bushing 42 - into which the carrier body 47 is inserted. A flange-like projection 49 is formed as a stop on the inner wall of the outer bushing 42.

As a result of the inwardly protruding mandrel profile 48 of the outer bushing 42, a reliable seal can usually also be achieved in addition to the fixation. Due to the different materials of the preferably metallic outer bushing 42 and the carrier body 47 made of insulation material, the press connection between the carrier body 47 and the outer bushing 42 may leak if there are large temperature fluctuations because the carrier body 47 and the outer bushing 42 expand differently.

According to an in Figure 4 A modified data plug connector 140 is therefore provided which is basically constructed like the data plug connector 40. The unchanged components of the socket and also of the data plug are not described in more detail below and are also not provided with reference symbols in the drawing.

A supplementary sealing ring 150 is provided between the carrier body 147 of the data connector 140 and its outer socket 142 to secure the seal. Details of the construction of this embodiment of the invention are shown in the enlarged section Z from Figure 4 in Figure 5 shown.

Figure 5 shows the support body 147 and the outer socket 142, which are received in the sleeve 23 of the socket 1. One of the mandrels of the inwardly protruding mandrel profile 148 of the outer bushing 142 are shown in FIG Figure 3 omitted, the inner wall of the outer sleeve 142 being smooth and flat there. The carrier body 147 has a groove 151 in which the sealing ring 150 is received. After the carrier body 147 has been pushed into the outer bushing 142, the sealing ring 150 is pushed together between the bottom wall of the groove 151 and the inner wall of the outer bushing 142 and thus creates an additional sealing effect. Due to the high elasticity of the sealing ring 150, different Compensate for the material expansion coefficient of the carrier body 147 and the outer bushing 142. The sealing effect is thereby reliably improved.

In the Figure 5 The mandrel profiles 46, 143, 148 shown show how the individual mandrels of the mandrel profiles are designed and are pressed into the surrounding material in a sealing manner, so that the components held by the mandrel profiles 46, 143, 148 are securely and sealingly fixed in the socket.

To illustrate the structure of the socket 1 according to the invention with the data contacts 41 and the data connector 140, FIG Figure 6 An exploded view of the socket 1 is shown, the data connector 140 also being shown as an exploded view. Components of the socket housing 2 of the socket 1, the electrical contact 30 and the data contact 41 are compared to the embodiment described above in FIG Figures 1 to 3 identical and will not be described again.

In Figure 6 spring sleeves 52 can also be seen, which are placed on the two axial ends of the support body 147 and bear against the outer bushing 142. These spring sleeves encompass a shield for the plugs inserted into the data connector 140, so that contact is made with the shield through the socket outlet 1. These spring sleeves 52 are also shown in the sectional drawing according to fixed point 3.

The one opposite the socket 1, as shown in the Figures 1 to 3 is described, unchanged parts of the socket 1 in the Figures 4 to 6 provided with the original reference numerals. Changed parts are marked by reference numerals increased by 100.

The socket 201, as in a further variant of the invention compared to the previously described embodiments of the socket 1 according to FIGS Figures 1 to 7 is described differs in the way in which the data connector 240 and the contacts 230 for the electrical connection are fixed. In the embodiments described above, the data connector and the contacts for the electrical displacement were each pressed into the sleeves of the contact carrier.

The variant of the invention now described shows electrical contacts 230 and a data connector 240 which were cast in during the injection molding of the housing 202 and the contact carrier 220. For this purpose, instead of a mandrel profile with triangular mandrels, the electrical contacts 230 have a mandrel profile 233 with rectangular, groove-shaped mandrels, in whose groove-like recesses the injection molding material is poured. The outer socket 242 has a rectangular mandrel profile 243 instead of the outwardly protruding mandrel profile with triangular mandrels through grooves embedded in the outer wall of the outer socket 242, which is encapsulated in the same way when the housing 202 of the socket 201 is injection molded.

In the in Figure 7 In the example shown, the data connector 240 itself has also been produced by casting the carrier body 247 into the outer socket 242. For this purpose, the data contacts 241 have a contact body 245 with a mandrel profile 246 which is formed by rectangular grooves let into the contact body 245. A rectangular mandrel profile 248 protrudes inward from the inner wall of the outer bushing 242, so that the carrier body 247 made of insulation material can be cast into the outer bushing 242 accordingly.

Both variants, the electrical contacts 230 cast in the carrier body 220 and the outer socket 242 of the data connector 240 cast in the carrier body 220 and / or the carrier body 247 cast in the outer socket 242, can each also be combined with the other embodiments described above.

Figure 8 shows another embodiment of a socket 301 according to the invention, the structure and construction of which basically corresponds to the embodiments described above. A detailed description is therefore dispensed with; the above statements apply accordingly.

The socket 301 differs from the socket outlets described above, in particular from a comparison with FIG Fig. 2 can be seen through the connection diagram. This socket 301 has only four contacts 330 for an electrical connection and a data connector 340, which comprises a first outer socket 342a and a second outer socket 342b, which are each received separately in the support body 320 of the housing 302 of the socket 301.

Five data contacts 341 are received in each of the outer sockets 342a, 342b.

The number of external sockets, the data contacts in each external socket and / or the contacts for the electrical connection can be suitably varied in each embodiment by the person skilled in the art.
