Description

connector part with electrically connectable shields

The invention relates to a connector part for connection to a

Mating connector part, a connection arrangement with such a connector part and a method for producing a connection arrangement.

Connector parts that carry both data lines and power lines are sometimes referred to as hybrid connector parts. Such connector parts enable single-cable solutions and thus compact devices through a

Functional integration of contacts for electrical/optical power, signal and

Data transmission within a connector.

In an exemplary embodiment of a circular connector part, a hybrid

Device connector part has a housing screw connection for connection to a corresponding mating connector part. In practical designs, the

Housing screw connection must be made of a conductive material and thus represent an external EMC shield. The abbreviation EMC stands as usual for “electromagnetic compatibility” and describes the ability of a technical

device not to interfere with other devices through unwanted electrical or electromagnetic effects or, conversely, not to be interfered with by other devices.

The external EMC shielding thus protects the connector part from external electromagnetic coupling or radiation and vice versa external

Systems from interference from the connector part. Since within a hybrid

Since sensitive data signals are typically transmitted via the connector part, an additional “internal” EMC shield is usually provided. The internal EMC

Shielding protects the respective data lines from electromagnetic interference from the load lines within the connector part, which can also be referred to as power contacts. The inner EMC shielding and the outer EMC shielding can be electrically connected to each other or, alternatively, galvanically isolated from each other.

For example, the standards IEC 63171-7 (“SPE M12 Hybrid”) and IEC 61076- 2-117 (“M12-M40 Hybrid”) describe hybrid connector parts.

In general, there is a growing interest in hybrid interfaces.

The challenge is the increasing number of different variants of

connector parts and therefore a relatively complex production.

The object of the present invention is to simplify the production of connector parts.

This object is solved by an article having the features of claim 1.

Accordingly, a connector part for connection to a matching

Mating connector part several data lines, an inner shield surrounding the data lines on the outside, several arranged outside the inner shield

Cables and an outer shielding which surrounds the data cables, the inner shielding and the cables on the outside. It is provided that the inner shielding and the outer shielding each have a connection contact section for electrical contact with a respective counter contact, whereby the inner shielding and the outer

Shielding is electrically separated from each other and can be electrically connected to each other via the connection contact sections.

This is based on the realization that some users of such connector parts require an electrical connection between the outer and inner shielding, while other users want to keep the two shields galvanically separated from each other. The relevant standards (IEC 63171-6, IEC 63171-7, IEC 61076-2-113 and IEC 61076-2-117) do not specify whether the inner shielding and the outer shielding should be electrically connected or galvanically separated from each other. This means that manufacturers of connector parts are faced with the decision of whether to offer a hybrid connector part with separate or connected shielding or to provide different product variants. The proposed connector part solves this problem by allowing the decision on the electrical connection of the two shields to be made by the users themselves, namely by the user electrically connecting the connection contact sections of the two shields to each other or not. The connection contact elements can be connected to corresponding connections on a printed circuit board, e.g. by THR,

SMD or wave soldering or press-fit technology. With the design of the

PCB layouts, the user can define the wiring of the PCB connections and thus the shielding concept of the hybrid connector part. The inner

Shielding and the outer shielding each represent an EMC shield, as described at the beginning.

In this way, a variable shielding concept can be created for hybrid connector parts, in particular device connector parts, which, depending on the configuration, enables either an electrical connection or a galvanic separation of the potentials of the inner and outer shielding. This concept thus enables a reduced article variance. A reduced article variance allows the manufacturer of the

Connector parts initially offer cost and time advantages in the development process. Furthermore, costs in procurement, assembly, quality assurance, storage and

The time required to represent articles in computer systems can be reduced. At the same time, the benefit for

Users benefit from the flexibility of a variable solution. Furthermore, the risk of

Confusion of articles with connected shielding potentials and with separate

shielding potentials can be reduced.

The connector part is constructed, for example, in accordance with the standard IEC 63171-6, IEC 63171-7, IEC 61076-2- 113 or IEC 61076-2-117. The cables arranged outside the inner shielding are in particular electrical cables, e.g.

Signal lines and/or power lines, in particular load lines for carrying a load current.

The inner shielding can be replaced inside the outer shielding by an outer

Insulating body must be electrically insulated from the outer shield. This enables safe insulation and at the same time a stable mounting.

The — connection contact section of the inner shield and/or the

Connection contact section of the outer shield is/are e.g. (each) in the form of a

pin. This enables particularly simple electrical contact, for example on a circuit board.

The connection contact section of the inner shield and the connection contact section of the outer shield can be aligned parallel to each other. This allows the two connection contact sections to be connected in a simple manner, e.g. in one step with a

circuit board can be electrically connected.

The — connection contact section of the inner shield and/or the

The connection contact section of the outer shielding and/or the connection contact sections of the data lines and/or the connection contact sections of the (outer) lines can be plugged into holes in a circuit board. This means that the connector part can be easily plugged onto a circuit board in one step.

The outer shielding can form a housing screw connection. The outer

Shielding can have at least one thread. This enables a secure

Fastening to a housing and/or with a mating connector part.

The connection contact section of the outer shielding can be formed on a contact spring. The contact spring is optionally spring-elastically pre-tensioned against a base body of the outer shielding. This enables easy production of the

base body and at the same time a secure electrical contact with the

connection contact section.

According to one aspect, a connection arrangement is provided, comprising the

Connector part according to any embodiment described herein and a

PCB. Regarding the advantages, please refer to the above comments on

connector part is referred to.

The mating contact for the connection contact section of the inner shield and the

Counter contact for the connection contact section of the outer shield can be electrically separated from each other. The inner shield is thus separated from the outer

Shielding is galvanically isolated and the connector part is suitable for applications in which such separation is specified.

The mating contact for the connection contact section of the inner shield and the

Counter contacts for the connection contact section of the external shielding can be electrically connected to different ground or reference potentials. This ensures effective EMC shielding.

Alternatively, the counter contact for the connection contact section of the inner

Shielding and the counter contact for the connection contact section of the outer

Shielding must be electrically connected to each other. The connector part is then suitable for applications in which an electrical connection between the two potentials is required.

Optionally, the mating contact for the connection contact section of the inner shield and the mating contact for the connection contact section of the outer shield are electrically connected to one another and/or operatively connected via at least one electrical or electronic component. In this way, completely new application possibilities are provided, such as monitoring of the shields and/or a selective electrical connection of the two shields.

The at least one component may comprise a resistor, an inductance, a capacitor, a diode and/or a varistor. Optionally, a network of such and/or other components is provided. This allows a complex analysis of the

Shielding potentials and a targeted influence on the properties of the shielding system are also possible.

The mating contact for the connection contact section of the inner shield and the

Counter contacts for the connection contact section of the outer shielding can be formed on different circuit board layers of the circuit board. This allows the shielding potentials to be routed separately from one another.

According to one aspect, a method for producing a connection arrangement, in particular according to any embodiment described herein, is provided. The

The method comprises the following steps: producing or selecting a printed circuit board with

Counter contacts, and electrical contacting of the connection contact sections of a

Connector part according to any embodiment described herein with the

Counter contacts of the circuit board. It is intended that the circuit board is manufactured or selected in such a way that the counter contacts for the

Connection contact section of the inner shielding and for the connection contact section of the outer shielding are or will be electrically separated from each other or electrically connected to each other. With regard to the advantages, reference is made to the above

Reference is made to the statements on the connector part.

The idea underlying the invention will be explained in more detail below using the embodiments shown in the figures. They show:

Fig. 1 to 5, to which reference is made together, show a connector part 1 for connection to a mating connector part 2. In the present case, the

Connector part 1 is designed as a circular connector part, specifically as a hybrid device connector part. An exemplary circuit board 30 is also shown, which together with the connector part 1 forms a connection arrangement 3. In the assembled state, the connector part 1 rests against the circuit board 30 and is electrically connected to it.

The connector part 1 comprises several, here two, (electrical) data lines 10 and an inner shield 12 surrounding the data lines 10. The data lines 10 can also be referred to as data contacts. The inner shield 12 has a

Base body 123 in which the data lines 10 are arranged. The base body 123 is sleeve-shaped. The inner shield 12 is made of an electrically conductive material, in this case of a metal, such as aluminum or

Brass. The inner shield 12 provides EMC shielding for the data lines 10. The inner shield 12 is designed in the form of a shield plate.

Furthermore, the connector part 1 comprises outside the inner shielding 12 arranged

Lines, which are shown here as load lines 11 by way of example (whereby the lines 11 may alternatively or additionally also be further data lines, signal lines or generally

power lines), and an outer shield 13. In the example shown, the load lines 11 have a larger cross-section than the data lines 10.

The load lines 11 are used to transmit load currents, e.g. to supply power to a device with the connector part 1 or to supply power through a device with the connector part 1. The outer shield 13 surrounds the data lines 10, the inner shield 12 and the load lines 11. The outer shield 13 has a

Interior in which the inner shield 12 with the arranged therein

Data lines 10 and, next to them, the load lines 11 are arranged. The outer

Shielding 13 provides EMC shielding for the data lines 10 and the load lines 11.

The outer shield 13 is made of an electrically conductive material, in this case a metal such as aluminum or brass. The outer shield 13 has a thread 131 for a nut 16. In this case, the outer shield 13 forms a housing screw connection. By means of the nut 16 screwed onto the thread 131, the connector part 1 can be screwed to the wall in an opening in a wall. The outer shield 13 also has a base body 133, on which (next to the thread 131 for the nut 16) a thread 134 for a matching

Counter thread of the mating connector part 2. The base body 133 thus serves both as external EMC shielding, as well as for housing screwing and for

Screw connection with the mating connector part 2.

Furthermore, contacts for a protective earth “PE”, a functional earth “FE”,

Shield contacts and additional signal contacts must be integrated.

Furthermore, the connector part 1 comprises an inner insulating body 14. As can be seen in particular from Fig. 5, the data lines 10 are held by the inner insulating body 14. The inner insulating body 14 encloses the data lines 10. Plug contact ends of the data lines 10 protrude from the inner

insulating body 14. On the opposite side of the inner insulating body 14, connection contact sections 100 of the data lines 10 protrude from the inner

Insulating body 14 protrudes. The connection contact sections 100 of the data lines 10 are used for insertion into holes 303 of the circuit board 30. Furthermore, the inner

Insulating body 14 has locking elements 140, by means of which the inner insulating body 14 is locked in the assembled state with corresponding locking elements 152 of an outer insulating body 15. A positive connection secures the position. For this purpose, the inner

Insulating body 14 has at least one locking hook which, during assembly, is

Undercut of the outer insulating body 15 is locked. The inner insulating body 14 electrically insulates the data lines 10 from the inner shielding 12.

The connector part 1 further comprises the outer insulating body 15. The outer

Insulating body 15 carries the load lines 11 and the inner shielding 12 including inner

Insulating body 14 and data lines 10. The outer insulating body 15 has a

Cylinder section 151, in and along which the load lines 11 and the inner

Shielding 12 including inner insulating body 14 and data lines 10. The outer

In the example shown, the insulating body 15 and the base body 133 do not lock together. These parts are not attached to one another by the connector construction. The outer insulating body 15 is firmly connected to the circuit board 30 via the connection contact sections 100. The circuit board 30 is attached in a device, e.g. by screws or clamps. This secures the position of the outer insulating body 15 to the base body 133, which is also attached to the device. This means that no force is required during assembly, which could cause the circuit board to bend, and it is possible to open the housing easily without releasing any locks.

The outer insulating body 15 has feet 150 with which the connector 1 is in contact with the circuit board in the assembled state. Positioning pins 153 are designed to be inserted into holes 303 in the circuit board 30 in order to ensure correct positioning. The inner

Shielding 12 inside the outer shielding 13 is electrically insulated from the outer shielding 13. On one side, plug contact ends of the load lines 11 are provided for plugging into corresponding mating plug contacts of the

Mating connector 2 in the outer insulating body 15. On the opposite side of the outer insulating body 15 are

Connection contact sections 110 of the load lines 11 protrude from the outer insulating body 15. The connection contact sections 110 of the load lines 11 serve to be inserted into corresponding holes 303 of the circuit board 30.

The data lines 10, the inner insulating body 14 and the inner shielding 12 form a pre-assembled subassembly. The subassembly is inserted into the outer insulating body 15 with the load lines 11 during assembly.

The connector part 1 is optionally designed according to one of the standards IEC 63171-6, IEC 63171-7,

IEC 61076-2-113 or IEC 61076-2-117.

The inner shielding 12 and the outer shielding 13 each have a

Connection contact section 120, 130 for electrical contact with a respective counter contact 300A, 300B, which will be explained in more detail below. The inner shield 12 and the outer shield 13 are electrically separated from each other. The inner

Shielding 12 and the outer shielding 13 can be electrically connected to one another via the connection contact sections 120, 130. The connection contact sections 120, 130 are spaced apart from one another.

The connection contact section 120 of the inner shield 12 is formed in the example shown by a shielding line 121, which is inserted into a receptacle 122 of the inner

Shielding 12. The shielding cable 121 is connected to a shielding cable of the

Mating connector 2 can be electrically contacted.

The connection contact section 130 of the outer shield 13 is formed on a contact spring 132. The contact spring 132 is spring-elastically pre-tensioned against the base body 133 of the outer shield 13. The contact spring 132 has several spring arms 136. The contact spring 132 is pre-tensioned against the base body 133 of the outer shield 13. In this case, the contact spring 132 is supported on a shoulder 154 of the outer insulating body 15. In the example shown, the shoulder 154 borders on one end of the cylinder section 151 of the outer insulating body 15.

The contact spring 132 is pushed laterally onto the outer insulating body 15. The

Contact spring 132 also has an opening 137. The opening 137 is in the assembled

State is placed on a positioning pin 155 of the outer insulating body 15. The

Positioning pin 155 is aligned perpendicular to the direction in which the spring arms 136 press against the base body 133 of the outer insulating body 13.

The connection contact section 120 of the inner shield 12 and the

Connection contact section 130 of the outer shield 13 are each designed in the form of a pin. The connection contact section 120 of the inner shield 12 and the

Connection contact section 130 of the outer shield 13 are aligned parallel to each other. The connection contact section 120 of the inner shield 12 and the

Connection contact sections 130 of the outer shield 13 can each be inserted into a hole 303 of the circuit board 30.

Thus, a potential electrical connection point between the inner and outer shielding 12, 13 is not realized within the connector part 1, but outside the connector part 1 and on the circuit board layout of the respective

Application. For this purpose, the inner and outer shielding 12, 13 are galvanically separated from each other as described. Both shielding potentials are separated, each with at least one connection contact section 120, 130, from the

Connector part 1 is led out. The connector part 1 can also be used as

PCB connector part. The respective wiring of the

For PCB connections, the user defines whether the inner shielding 12, 13 is electrically connected to the outer shielding 12, 13 or not.

With reference to Figs. 6A to 12C, steps of an exemplary manufacture of the connection arrangement 3 will now be described below. A side view is shown at the top (e.g. Figs. 6A and 7A), and in the middle a top view in a case in which the inner and outer shielding 12, 13 in the

connection arrangement are electrically isolated from each other (e.g. Fig. 7B and 8B), and below a plan view in a case in which the inner and outer shields 12, 13 are electrically connected to each other in the connection arrangement (e.g. Fig. 7C and 8C).

First, a circuit board layout is developed for an application, usually using circuit board design software. This defines the details of the circuit board and thus also the wiring of the circuit board connections. This

Step, whether the inner and outer shielding 12, 13 are connected. A printed circuit board

Design file is especially in a common format (e.g. as a Gerber file or as

Zuken archive) to a PCB manufacturer. Then a

PCB material is selected. This could be an insulating

PCB base material (e.g. FR4) onto which conductive coatings (e.g. copper foils) have already been applied (on one or both sides). This is shown in Fig. 6A-6C.

The next step involves the creation of the conductor pattern. Conductor and pad patterns are removed using an ablating process (e.g. etching, milling or lasering).

Geometries are exposed from the conductive coating. This creates the

Counter contacts 300A, 300B, 300C for the connection contact sections 100, 110, 120, 130 of the data lines, the load lines, the inner shielding 12 and the outer shielding 13. Furthermore, an electrical connection line 301 is created between the counter contacts 300A, 300B of the inner and outer shielding 12, 13 if this is required in the design file. From a cost perspective, the thus manufactured

Connection neutral, because the removal or non-removal of the connection on the circuit board 30 does not result in any additional costs.

For circuit boards with conductive inner layers, these steps are carried out for each inner layer. The individual circuit board levels are then stacked and pressed together to form a circuit board. Fig. 7A-7C show the circuit board 30 after the conductor pattern has been produced.

The next step involves drilling and optionally galvanizing.

In this case, holes 303 are produced, for example for the connection contact sections 100, 110, 120, 130 and positioning pins 153 of the connector part 1. Conductive

Connections between conductors in different circuit board levels, so-called

Vias are created in an optional downstream galvanic or chemical deposition process. Then optional solder mask and/or

Printing is applied. Additional process steps can be used to produce the

Circuit board contours follow. This usually involves separating processes such as milling, sawing or scoring. Fig. 8A-8C show the circuit board 30 after the holes have been made.

In a subsequent step, the circuit board is assembled.

Connector part 1 (optional as shown except for the housing screw connection from the

The base body 133 of the outer shield 13 and the nut 16) is assembled manually or automatically. For automatic assembly, a suction cap can be attached to the

Connector part 1 may be provided to position the product with a vacuum gripper. The connection between the connection contact sections 120, 130 of the inner and outer shielding 12, 13 of the connector part 1 and the counter contacts 300A, 300B may be realized using a press-fit technique. In this case, the circuit board 30 is then fully assembled. If the connection is to be made using SMD or THR reflow soldering processes, a solder paste is applied to the circuit board before assembly.

PCB connections. Fig. 9A-9C show the parts of the

Connector part 1 assembled circuit board 30.

In a further step, the connection contact sections 100, 110, 120, 130 of the connector part 1 are soldered, e.g. by SMD, THR, wave or hand soldering processes.

After this step (or after the previous step in the case of press-fit technology), the connection contact sections 120, 130 of the inner and outer shielding 12, 13 are connected in a material-locking manner (in the case of press-fit technology, force-locking) to the counter contacts 300A, 300B of the circuit board 30. Fig. 10A-10C show the soldered at soldering points 304.

Connector part 1 (in the example shown, except for the housing screw connection, consists of the base body 133 of the outer shield 13 and the nut 16). The contact spring 132 of the outer shield 13 is already mounted on the outer insulating body 15.

Then (or at an earlier point in time) the base body 133 of the outer

Shielding 13 is mounted in a panel or a control cabinet wall or another housing wall 4 and screwed thereto by means of the nut 16, see Fig. 11A and 11B.

Finally, the assembled and soldered circuit board 30 is installed in a device, see

Fig. 12A-12C. In this step, the internal components of the hybrid

Connector part 1 is joined to the housing screw connection. The contact spring electrically connects the housing screw connection to the corresponding connection contact section 130. Depending on the configuration of the circuit board layout, there is now an electrical

Connection of the inner and outer shielding 12, 13, or the shielding potentials are separate or are connected differently (see below).

According to Fig. 12B, the mating contact 300A for the connection contact section 120 of the inner shield 12 and the mating contact 300B for the connection contact section 130 of the outer shield 13 are electrically separated from each other.

According to Fig. 12C, the mating contact 300A for the connection contact section 120 of the inner shield 12 and the mating contact 300B for the connection contact section 130 of the outer shield 13 are electrically connected to one another via the connecting line 301 of the circuit board 30.

In general, a method for manufacturing the connection arrangement 3 may include the following steps: (a) manufacturing or selecting the printed circuit board 30 with mating contacts 300A-300C and (b) electrically contacting the

Connection contact sections 100, 110, 120, 130 of the connector part 1 with the

Counter contacts 300A-300C of the circuit board 30, wherein the circuit board 30 is manufactured or selected such that the counter contacts 300A, 300B for the

Connection contact section 120 of the inner shield 12 and for the

Connection contact section 130 of the outer shield 13 are optionally electrically separated from each other or electrically connected to each other.

Various possibilities are conceivable for the concrete design of the printed circuit board 30, with several examples being described below.

In the alternative according to Fig. 12B, the connection contact sections 120, 130 of the inner and outer shielding 12, 13 of the connector part 1 are only made of mechanical

reasons connected to the circuit board terminals and electrically isolated from each other.

Fig. 19B shows a corresponding circuit diagram.

In the alternative according to Fig. 13A and 13B, the circuit board 30 has a top side with a conductive circuit board layer 302A (Fig. 13A) and a bottom side with a conductive

PCB layer 302B (Fig. 13B). The mating contacts 300A, 300B (in the form of

The central circuit board connections (PCB connections) of the inner and outer shielding 12, 13 are electrically connected to the different outer circuit board layers 302A, 302B. In the example shown, the central circuit board connection, the counter contact 300A of the inner shielding 12, is electrically connected on the underside to the so-called bottom layer as an outer conductive circuit board layer 302B of the circuit board 30 by means of a contact 305. The counter contact 300B of the outer

Shielding 13 is electrically insulated from this circuit board layer 302B. The

PCB connection with the counter contact 300A of the outer shield 13 is connected to the

Top layer as a further outer circuit board layer 302A is electrically connected by means of a contact 305. The counter contact 300A of the inner

Shielding 12 is electrically isolated from this PCB layer 302A. The top and bottom

Layers are galvanically separated from each other. This allows, for example, different ground or reference potentials to be implemented for the inner and outer shielding 12, 13.

Fig. 14 shows another example with electrically connected counter contacts 300A, 300B of the inner and outer shielding 12, 13 according to the circuit diagram of Fig. 19A. Here, the counter contacts 300A, 300B are electrically connected to the same ground or reference potential. For this purpose, both counter contacts 300A, 300B are connected via contacts 305 in the same electrically conductive circuit board layer. An alternative

The embodiment is shown in Fig. 13A, 13B and 15, if the mass or

Reference potentials within the circuit board 30 are electrically connected to one another.

According to Fig. 15, the terminal contact sections 120, 130 of the inner and outer

Shielding 12, 13 connected to different inner PCB layers 302C, 302D. In the example shown, the central counter contact 300A of the inner

Shielding 12 is connected to a first inner conductive circuit board layer 302D and the

Counter contact 300B of the outer shield 13 to a second inner conductive

Printed circuit board layer 302C. The printed circuit board layers 302C, 302D are galvanically separated from each other. The embodiments according to Fig. 13A and 13B and according to Fig. 15 can be combined as desired. For example, another embodiment could be achieved by connecting the inner and outer shields 12, 13 in an outer and an inner

PCB layer.

According to Fig. 16, the mating contacts 300A, 300B are each connected via a connecting line 308A, 308B to different fields 309 and thus to ground or reference potentials on the same circuit board layer.

According to Fig. 17, the mating contacts 300A, 300B are each connected via a connecting line 308A, 308B to different ground or reference connections, which lead, for example, to other circuit board levels or other system components.

According to Fig. 18, the mating contact 300A for the connection contact section 120 of the inner shield 12 and the mating contact 300B for the connection contact section 130 of the outer shield 13 are connected via (at least) an electrical or electronic

Component 31 is electrically connected to one another. The use of at least one electrical or electronic component 31 between the

Shield potentials. For this purpose, an interrupted connection point in a

Connecting line 301 is provided between the counter contacts 300A, 300B of the inner and outer shielding 12, 13. The interruption is equipped with at least one or more (series and/or parallel connection, SMD and/or THR) component(s) 31. Alternatively, the connection can also be made between the counter contacts 300A, 300B and the ground or reference planes of a printed circuit board. This

Arrangement allows, for example, the installation of defined resistors, inductors, or

Capacitances and networks of these components. Such an arrangement can be used, for example, to optimize the asymmetry attenuation if the inner shielding with the common mode impedance of the data line(s) 10 is terminated against the outer shielding or a ground plane. Furthermore, the data lines 10 can be connected with their

Differential impedance against the inner and/or outer shielding 12, 13, for example to terminate a transmission line. This application is particularly interesting for multidrop applications.

Furthermore, low-pass, band-pass or high-pass filters as well as resonant circuits between the

Shielding potentials can be provided. These can increase the shielding potentials in certain

operating states. Further embodiments result from the use of one or more diodes or one or more varistors, which only allow coupling in one direction or in the event of a fault.

From this point of view, interference from the inner shielding 12 could be diverted to the outer shielding 13, but no external interference could be diverted to the inner

shielding 12 of the data lines 10.
