Description

Field of the Invention

[0001] The present invention relates to a shielded electrical plug according to the preamble of the independent claim, an electronic component including the shielded electrical plug, and a method for constructing the electronic component. Background Art

[0002] In various electronic fields, especially in driver assistance systems and autonomous driving, it is necessary to transmit communication data at high speed. Such communication data can be generated, for example, by detecting certain environmental parameters by means of sensors and / or cameras, and / or by processing and / or forwarding it by means of, for example, a vehicle computer VCU (Vehicel Computer Unit) or other computing units. To ensure high-speed data transmission and to guarantee the required EMV (Elektromagnetische electromagnetic compatibility) in the range of several gigabits (high-speed data transmission, especially gigabit Ethernet), the lines and plug-in systems used at these data rates must be shielded. A variety of plug-in systems for high-speed applications are known on the market. Here, for example, copper stamping bends can be used as shielding elements. However, due to manufacturing and / or design reasons, the shielding solutions that can be achieved thereby usually have residual openings, so the shielding quality is limited in this case. An alternative shielding solution is achieved by a die-cast housing, but the optional connection options of such plug-in systems to the circuit board are very limited.

[0003] A shielded electrical plug is known from the published document DE102019219411, in which a die-cast housing is used as the shielding housing, and the shielding housing is closed on the side facing the connection side connected to the circuit carrier by a molded plate member. The molded plate member is connected to the die-cast housing by molded press-fit pins. In addition, the molded plate member also has molded press-fit pins on its opposite side as a mechanical connection interface for connecting the plug to the circuit carrier. However, in order to achieve good shielding, a large number of press-fit pins must be positioned at a small spacing (depending on the frequency range). Otherwise, the gap between the press-fit pins will become larger and thus the performance of the plug will deteriorate due to the EMV ( electromagnetic compatibility) holes existing in the area of the press-fit pins. Summary of the Invention

[0004] The object of the present invention is to achieve a cost-effective plug system that enables data transmission in the Gbit / s range and has very simple and flexible feasible connection options for connecting to the circuit carrier.

[0005] This object is achieved by a shielded electrical plug according to the independent claim, an electronic component including the shielded electrical plug, and a method for forming the electronic component.

[0006] The present invention relates to a shielded electrical plug, comprising a shielding housing for shielding electromagnetic radiation and at least one data line arranged within the shielding housing, which data line enables data transmission in the Gbit / s range. The data line hereby has at least one plug-in side of the data line for electrically contacting the contact connection of the plug with a complementary corresponding plug, and the data line also has a connection side of the data line for electrically contacting a circuit carrier, wherein at least one data line is surrounded by the shielding housing at least between the plug-in side and the connection side. Herein, the shielding housing comprises at least one first shielding housing part closed at the connection side and at least one second shielding housing part arranged in the direction towards the plug-in side and following the first shielding housing part, which second shielding housing part is in conductive contact with the first shielding housing part. Furthermore, the first shielding housing part has at the connection side a first wall end section radially enclosing at least one data line, which first wall end section is used to connect the plug and the circuit carrier without gaps along the wall contour by means of an adhesive. A gapless connection can be achieved, for example, by means of a soldering layer, alternatively by means of an EMV-tight (EMV-dicht) adhesive or other such adhesives. The advantage achieved hereby is that by connecting without gaps by means of an EMV-tight adhesive, otherwise disadvantageous EMV gaps can be very easily closed, especially at the connection side of the plug. Thereby the plug can be easily applied to applications with higher EMV requirements. At the same time, by modularly designing the plug by means of at least one first shielding housing part and a second shielding housing part, the plug can be soldered in a process-reliable manner. This is because the plug does not need to be assembled as a whole and then soldered under difficult conditions. Instead, the plug is constructed to be partially assembled, so that the first shielding housing part, which is a separate part of the plug (i.e., separated therefrom), can be soldered to the circuit carrier only under much simpler and more reliable process conditions. The modular plug structure in combination with the radially enclosing wall part of the first shielding housing part for soldering provides new flexibility for an EMV-optimal connection of the plug to the circuit carrier. In particular, a rectangular, circular or oval wall contour is hereby an advantageous interface both for at least conductive contact with the at least second shielding housing part and for soldering to the circuit carrier. Furthermore, for other reasons, such as to facilitate the assembly of the plug itself, the shielding housing can have other shielding housing parts arranged after the second shielding housing part. The shielding effect of the shielding housing is especially because the parts constituting the shielding housing (i.e., at least the first shielding housing part and the second shielding housing part) contain metal or are made of metal.

[0007] Advantageous improvements and refinements of the plug according to the invention can be made by means of the measures listed in the dependent claims.

[0008] In an advantageous embodiment of the plug, the first shielding housing part has a second wall end section which faces the first wall end section of the second shielding housing part, wherein a connection area is constructed between the two wall end sections by means of a form-fit connection, a force-fit connection and / or a material connection. By means of this connection area, the overall assembly of the plug can be carried out after connecting the first shielding housing part to the circuit carrier. This connection area ensures that the two shielding housing parts, more precisely the first shielding housing part and the rest of the plug, remain connected during the operation of the plug. This connection can be permanent, for example, by means of a material connection using a soldering agent or an adhesive. However, a permanent connection achieved by means of a force-fit connection, in particular by means of a press fit between the first shielding housing part and the second shielding housing part, can also be considered. Alternatively, a detachable connection can be provided by means of a force-fit connection and / or a form-fit connection, for example by means of a snap connection, wherein the two shielding housing parts have corresponding snap parts which are complementary to each other and engage into each other in the connection area. The snap connection can be disassembled subsequently, for example, by applying a force exceeding the snap retention force against the engagement direction. If necessary, the snap parts can be released from their engaged state again, for example, by correspondingly pressing using a disassembly tool, in particular with a disassembly force below the snap retention force. This feasible disassembly solution enables subsequent repair of the plug or a plug unit containing the plug.

[0009] In a particularly advantageous embodiment of the plug, the two wall end sections of the first shielding housing part and the second shielding housing part facing each other are at least partially covered to form an electrically conductive abutment contact line or an abutment contact surface. By means of the abutment contact line or the abutment contact surface, a shielding effect is correspondingly obtained between the two shielding housing parts. In order to eliminate EMV vulnerabilities, a covering area is provided, in particular in the connection area. In this way, any required interruptions in the connection area can be closed, so that an effective shielding can also be maintained uninterruptedly here. Due to the type of the constructed connection area, interruptions may occur. For example, in the case of a snap connection, the punching part is an interruption. In addition to such snap parts, other types of connection parts can also be considered, which may locally form EMV vulnerabilities on at least one of the shielding housing parts. In order to eliminate such EMV vulnerabilities, such connection parts of at least one shielding housing part are covered by the constructed abutment contact surface.

[0010] The assembly performance of, in particular, the first shielding housing part and the second shielding housing part can be improved by providing guide elements with complementary configurations on two facing wall end sections of the first shielding housing part and the second shielding housing part, which guide elements are configured to determine a defined position of the two shielding housing parts relative to each other during plug assembly. Here, an assembly start state is formed at the position where the guide elements first engage with each other, from which assembly start state the two shielding housing parts can be axially moved relative to each other on a guide path, in particular in the direction towards the connection side, until they reach an assembly end state. Particularly advantageously, in particular in the assembly end state, a conductive abutting contact line or abutting contact surface is formed by the action connection of the guide elements with complementary configurations. In this form, the position of the first shielding housing part is transferred to the second shielding housing part, more precisely to the rest of the plug, by the guide elements. In addition, the assembly of the plug can be carried out very conveniently and with high precision repeatedly. A particular advantage of this guidance is that one of the shielding housing parts is at least partially and shape-fittingly inserted into the receiving opening of the other shielding housing part from the side of the facing wall end sections. Here, the regions of the respective inner and outer peripheral surfaces of at least these two shielding housing parts facing each other are used as two guide elements with complementary configurations. Overall, a very compact and mechanically stable plug design is achieved in this way. A particularly compact but functionally reliable embodiment is that at least two, in particular opposite, guide elements on one of the facing wall end sections, in particular on the end-side end face, are configured to protrude to the maximum extent. They protrude in the form of wall connecting tabs, in particular. In addition, they abut shape-fittingly and conductively against at least one corresponding wall surface of the other wall end section on the guide path, at least in the assembly end state.

[0011] It is generally appropriate for functional reliability that at least one connection part forming a connection area in at least one of the shielding housing parts is covered by the formed abutting contact surface.

[0012] The following embodiment of the plug also has advantages, in which the first shielding housing part has at least one positioning part on its first wall end section facing the connection side, which is configured to position the first shielding housing part or the plug relative to the circuit carrier when acting in connection with a complementary configured positioning part on the circuit carrier. Thus, after connecting the first shielding housing part as a single unit to the circuit carrier, the subsequent spatial orientation of the plug in the overall assembled state can be determined very precisely by connecting the two shielding housing parts. For cost-effective and convenient implementation, the first shielding housing has at least one, two or more protruding cylindrical positioning parts, especially in the form of plug pins, which engage into corresponding recesses in the circuit carrier. The plug pins protrude in particular from the end face of the first wall end section in the direction of the circuit carrier. However, other forms of cooperating positioning parts can also be considered.

[0013] For the purpose of very conveniently assembling the plug, especially also in view of the staggered assembly in terms of time of the first shielding housing part soldered to the circuit carrier and the rest of the plug, at least one data line is configured as a plug pin, wherein on the connection side the plug pin is configured as a press-fit pin. The press-fit pin can additionally achieve a holding force, which holds the plug in the overall assembled state or strengthens this holding in addition to the connection area between the two shielding housing parts. In particular, in this way the first shielding housing part can be clamped between the circuit carrier and the second shielding housing part. A simple and cost-effective embodiment is that the first shielding housing part is especially configured as a stamped sheet or laser-cut sheet made of, for example, copper or a copper alloy. The press-fit pin has a press-fit zone, which is especially configured as an embossed area.

[0014] An optimal embodiment of the plug is that the plug pins of the data line are arranged relative to the end face of the first wall end section of the first shielding housing part such that their exposed ends have a minimum dimension from the end face in the axial direction towards the connection side in the start state of the assembly, and in the end state of the assembly they project beyond this end face in the axial direction towards the connection side with a minimum axial dimension. This advantageously ensures that when assembling the rest of the plug and the first shielding housing part already connected to the circuit carrier, first the two assembly sub-components (i.e., the first shielding housing part and the rest of the plug separated therefrom) can be correctly oriented relative to each other by guiding, and thus at least one press-fit pin of the data line is also correctly axially oriented relative to the corresponding recess in the circuit carrier. Thus, at least one press-fit pin of the data line is reliably joined to the corresponding recess in a process-safe manner before reaching the end state of the assembly along the joining path. Blind assembly can thus be carried out, since the joining to the recess is ensured by the existing guiding path. As the end state of the assembly is reached, the press-fit zone is pressed into the recess.

[0015] In order to achieve particularly low costs but at the same time have a good shielding effect, in one embodiment, it can be provided for the plug that the first shielding housing part is constructed as a molded sheet metal part and the second shielding housing part is constructed as a die casting. As a die casting, even very complex and individually adjusted contact connection parts on the plug side can be realized. The die casting is especially made of zinc, zinc alloy, aluminum or aluminum alloy. In contrast, the molded sheet metal part can be provided as a very low-cost, solder-wettable, radially closed surrounding contour. It can also be envisaged to provide a plug series, in which at least two plug variants each have a die casting with a contact connection part of a different structure, but the first shielding housing part as a connection interface connected to the circuit carrier, more precisely the corresponding die casting, is designed in the same way. Therefore, the plug series has a first shielding housing part as an identical component, and various customer requirements for the contact connection part can be taken into account by the second shielding housing part.

[0016] The present invention also relates to an electronic component, comprising at least one shielded electrical plug according to at least one of the aforementioned embodiments. The electronic component also comprises at least one circuit carrier that is in electrical contact with at least one data line of the plug. The plug is connected to the circuit carrier without gaps along the wall contour in the region of the first wall end section of the first shielding housing part by means of a connecting agent, in particular a soldering material. The connection formed here comprises, for example, at least an end face of the first wall end section and / or an inner circumference section and / or an outer circumference section of the first wall end section.

[0017] In contrast, an alternative embodiment of the electronic component includes at least one group of two or more shielded electrical plugs according to at least one embodiment of the aforementioned embodiments and at least one circuit carrier. The circuit carrier is electrically contacted with at least one data line of two or more electrical plugs, respectively, wherein the group of two or more electrical plugs has a common shielding housing element. In the common shielding housing element, the corresponding first shielding housing parts of the two or more plugs are integrally constructed in the shielding housing element. In addition, the common shielding housing element has an end area on the side facing the circuit carrier, which frames all first wall end sections of the first shielding housing parts of the integral structure with a closed boundary contour. In addition, the group of two or more plugs are connected to the circuit carrier without gaps along the boundary contour in the end area of ​​the common shielding housing element by means of a connecting agent, in particular a soldering material. The connection formed here, for example, includes at least an end face and / or a peripheral surface section adjacent to the boundary contour of the end area.

[0018] In the two above-described embodiments of the electronic component, a high EMV can be ensured in the region of the connected plug. Advantageously, especially for large plug systems, such as a knife bar (Messerleister) having at least one, two or more plugs according to the invention, it is only possible to access the connection material located in the connection region where the plug is connected to the circuit carrier by dividing it into assembly sub-components in the manner described.

[0019] The invention also relates to a method for respectively forming the two above-described electronic components. In both cases, the electronic component is formed by means of at least two prefabricated assembly sub-components of the above-described plug.

[0020] For forming the first-described electronic component, the following method steps are proposed:

[0021] a) Position the first shielding housing part of the plug relative to the circuit carrier, wherein its first wall end section is arranged to face the circuit carrier, in particular perpendicular to the joining direction of the press-fit pins, in the region of at least one press-fit zone constructed in the circuit carrier for receiving the press-fit pins of the plug.

[0022] b) Connect the first shielding housing part of the plug to the circuit carrier without gaps along its wall contour in the region of the first wall end section by means of a connecting agent, in particular a soldering material, for example including at least the end face of the first wall end section and / or the inner circumferential surface section and / or the outer circumferential surface section of the first wall end section, to form the first assembly sub-component of the electronic component.

[0023] c) Construct the second assembly sub-component of the plug, including at least the second shielding housing part of the plug and at least one data line arranged in the second shielding housing part, which is radially surrounded by the second shielding housing part along a line section starting from its plugging side, and wherein a line section exposed relative to the connection side of the data line is left, and its exposed end is constructed as a press-fit pin.

[0024] d) Join the first assembly sub-component and the second assembly sub-component to form the electronic component, wherein the exposed end of at least one data line passes through the first shielding housing part starting from its connection side, and the press-fit pin is press-fitted into the press-fit zone, and wherein, in the end state of the assembly, a connection region is formed in the region of the wall end sections of the two shielding housing parts of the plug facing each other by means of a form-fit connection, a force-transmitting connection and / or a material connection.

[0025] The method for forming the second-mentioned electronic component includes very similar method steps, but takes into account a group of two or more plugs. Here, the following method steps are involved:

[0026] a) Position a common shielding housing part for at least two or more plugs relative to the circuit carrier, wherein the end region of the common shielding housing element is arranged to face the circuit carrier, in particular perpendicular to the engagement direction of the press-fit pins, in the region of at least one press-fit zone for accommodating at least two or more press-fit pins constructed in the circuit carrier.

[0027] b) Connect the common shielding housing element of at least two or more plugs to the circuit carrier without gaps along its boundary contour in the end region by means of a connecting agent, in particular a soldering material, for example including at least the end face and / or the outer peripheral surface section adjacent to the boundary contour of the end region respectively, to form a first assembly sub-component of the electronic component.

[0028] c) Construct at least one second assembly sub-component in the second assembly sub-components of the electronic component, the number of which corresponds to the first shielding housing part integrally constructed in the shielding housing element. The second assembly sub-component at least includes a second shielding housing part of the corresponding plug and at least one data line arranged in the second shielding housing part, the data line being radially surrounded by the second shielding housing part along the line section starting from its plugging side, and a line section exposed relative to the connection side of the data line is left, and its exposed end is constructed as a press-fit pin.

[0029] d) Join the first assembly sub-component and a plurality of second assembly sub-components to form an electronic component, wherein at least one data line of the corresponding second assembly sub-component respectively passes through the first shielding housing part constructed in its assigned common shielding housing element starting from its exposed end, and presses its press-fit pin into the corresponding assigned press-fit zone constructed in the circuit carrier, and wherein in the corresponding assembly end state, a connection region is formed by form-fit connection, force-transmitting connection and / or material connection in the region of the facing wall end sections of the corresponding two shielding housing parts of two or more plugs.

[0030] In the method for forming the above two electronic components, a special embodiment can be proposed as follows.

[0031] A special embodiment of the described method is obtained by positioning in the respective method step a) as follows: making the positioning parts respectively constructed complementary to each other in the first shielding housing part and the circuit carrier act on each other for connection. Particularly suitable is to insert at least one of the plug pins protruding from the end face of the first wall end section as at least one of the positioning parts into the recess constructed in the circuit carrier as the complementary positioning part. In principle, in the method for forming the second described component, only two positioning parts can be provided on the common shielding housing element, for example on two opposite sides of the shielding housing element.

[0032] Another embodiment of the described method enables the joining of a first assembly sub-component and a second assembly sub-component. Specifically, an assembly start state is formed during the passage of at least one data line through the first shielding housing part starting from its exposed end and before the press-fit pins are joined to the press-fit areas constructed in the circuit carrier, in which the guiding elements of the two shielding housing parts that are complementary to each other are operatively connected. The guiding elements are positioned in a defined position by a guiding path that extends axially in the direction towards the joining side and terminates in the assembly end state. However, before reaching the assembly end state, the press-fit pins are inserted into the press-fit areas and then pressed there, thereby joining the first assembly sub-component and the second assembly sub-component.

[0033] The various methods have the same advantages as those already mentioned for the plug. Description of the Drawings

[0044] Figure 1a shows a perspective view of a cut-out portion of an electronic component 200, which includes a shielded electrical plug 100 in electrical contact with a circuit carrier 10. The shielded electrical plug 100 has a shielding housing 110 that radially surrounds at least one data line 120 arranged within the shielding housing 110 and shields it from radiation or external electromagnetic radiation that may occur. This shielding particularly ensures the interference-free transmission of data signals through at least one data line 120. Such shielding is particularly important for data lines 120 that achieve data transmission in the Gbit / s range. The at least one data line 120, more precisely the plug 100, has a mating side S here, for example, a complementary corresponding plug 100' of another electronic unit can make contact with the electrical plug 100 through this mating side. On the side opposite the mating side S, a connection side A of the at least one data line 120, more precisely the plug 100, is constructed. This connection side is the side where the plug 100, more precisely the at least one data line 120, makes electrical contact with the circuit carrier 10. In the present embodiment, the shielding housing 110 is divided into two parts, but it may also have additional shielding housing components. Thus, the shielding housing 110 includes a first shielding housing component 110.1 at the side facing the connection side A. The first shielding housing component 110.1 ends at least at the terminal relative to the connection side A in a radially closed, surrounding first wall end section 110.1a. Preferably, but not necessarily, the end face 110.1s of the first wall end section 110.1a contacts the top surface 11 of the circuit carrier 10. The wall profile 111 of the first shielding housing component 110.1 in the region of the first wall end section 110.1a is, for example, of a closed rectangular design, optionally with a rounded corner design. Alternatively, an elliptical, circular, or symmetric n-sided cross-section may also be advantageously provided. At the wall end section 110.1a, the first shielding housing 110.1 is connected to the top surface 11 of the circuit carrier 10 without gaps by means of an EMV-tight connecting material 50. This means that any gap between the first shielding housing component 110.1 and the circuit carrier 10 along the wall profile 111 is closed by the connecting agent 50. Usually, the connecting agent 50 is continuously arranged on the top surface 11 of the circuit carrier 10 along the wall profile 111. A metal brazing material is preferably selected as the connecting agent 50. Alternatively, an EMV-tight adhesive, for example, an adhesive including metal particles, may also be provided.

[0045] On the opposite side of the first wall end section 110.1a, a second wall end section 110.1b of the first shielding housing part 110.1 is constructed. Immediately adjacent to it is the first wall end section 110.2a of the second shielding housing part 110.2, which faces the second wall end section 110.1b of the first shielding housing part 110.1. A connecting area 110.12 is constructed in the area of the two wall end sections 110.1b, 110.2a facing each other between the first shielding housing part 110.1 and the second shielding housing part 110.2. In principle, this connecting area can be designed in the form of a form-fit connection, a force-transmitting connection, and / or a material connection. In Figure 1a a snap connection is exemplarily constructed as the connecting area 110.12, wherein complementary snap parts are arranged on the shielding housing parts 110.1, 110.2, which engage into each other and in this way hold the shielding housing parts 110.1, 110.2 connected.

[0046] Figure 1b is shown Figure 1a a sectional view A-A of the electronic component 200 in the vertical connection area connected to the circuit carrier 10 through the shielded electrical plug 100. It can be seen that the two wall end sections 110.1b, 110.2a coincide in the connecting area 110.12. Here, they touch at least in the area of the opposite circumferential surfaces, forming at least one conductive abutting contact line or conductive abutting contact surface 115. The end face 110.1s of the first wall end section 110.1a lies flat on the top face 11 of the circuit carrier 10 in this plane. According to the wall profile 111 of the wall end section 110.1a, an adhesive 50 is arranged adjacent to the end face 110.1s from the outside, and this adhesive connects the end wall section to the top face 11 of the circuit carrier 10 without a gap. Alternatively or additionally, the adhesive 50 can also be arranged between the end face 110.1s and the top face 11 and / or correspondingly from the inside according to the wall profile 111 of the wall end section 110.1a.

[0047] The plug 100 is electrically connected to the circuit carrier 10, more precisely to the circuit of the circuit carrier 10 (not shown), via at least one data line 120. In the present embodiment, for illustrative purposes only, two data lines 120 are arranged parallel to each other, and at their end sides facing the connection side A, they are each configured as press-fit pins 120.a. The data lines 120 are manufactured, for example, as stamped parts, for example from a plate base material made of copper or a copper alloy. The press-fit areas of the press-fit pins 120.a are then preferably pressed into corresponding recesses 15 of the circuit carrier 10. The recesses 15 are preferably metallized. The data lines 120 are also arranged, for example, within an insulating element 140, which in turn is accommodated within a second shielding housing part 110.2. Thereby, the two data lines 120 are positioned in a defined position electrically insulated from the second shielding housing part 110.2.

[0048] Figure 2a A perspective view before the formation of the electronic component 200 described according to the embodiment as Figure 1a or Figure 1b is shown. Here, a part of the plug 100 is provided in a partially assembled state, where at least the first shielding housing part 110.1 is still missing. This partially assembled state is hereinafter referred to as the second assembly sub-component 100.II. The second assembly sub-component 100.II here at least includes the second shielding housing part 110.1 and at least one data line 120 encapsulated therein. The insulating element 140 may also already be included. In the exemplary illustration, a line section exposed relative to the connection side A of the respective data line 120 is retained here, and its exposed end is configured as the press-fit pin 120.a already described.

[0049] With the provided circuit carrier 10 and the first shielding housing part 110.1, the first assembly sub-component 100.I is joined. Here, the first shielding housing part 110.1 is positioned with its first wall end section 110.1a relative to the top surface 11 of the circuit carrier 10 such that when the end surface 110.1s abuts against the top surface 11, the corresponding recesses 15 for the press-fit pins 120.a of the data lines 120 already constructed in the circuit carrier 10 are precisely framed by the wall contour 111 of the first shielding housing part 110.1. This precisely positioned location can be supported by positioning parts 14, 114 that are complementary to each other on the circuit carrier 10 and the first shielding housing part 110.1. For example, for this purpose, the plug-in pins 114 protruding from the end surface 110.1s of the first shielding housing part 110.1 engage into corresponding positioning recesses 14 in the circuit carrier 10. The first shielding housing part 110.1 is then connected to the top surface 11 of the circuit carrier 10 without gaps along the wall contour 111 using a bonding agent 50, for example a soldering material. Figure 2b A cut-out part of the first assembly sub-component 100.I is shown in perspective.

[0050] If there are already two assembled sub - components 100.I, 100.II, they are joined to each other to form an electronic component 200, as shown in FIG. 2. For this purpose, the respective exposed ends of the data line 120 pass through the first shielding housing part 110.1, such that the press - fit pins 120.a on the end side of the data line 120 are press - fitted into the corresponding recesses 15 in the circuit carrier. The press - fitting is carried out in the joining direction F here. For many applications, this joining direction is preferably perpendicular to the top surface 11 of the circuit carrier 10.

[0051] Figure 2d A cross - sectional view of the two assembled sub - components 100.I, 100.II at the time of joining is shown, in which the two shielding housing parts 110.1, 110.2 are joined into each other for the first time. In this initial assembly state, the guide elements 110.11, 110.22, which are respectively complementary to each other here in the two shielding housing parts 110.1, 110.2, are joined into each other to precisely position or orient the two assembled sub - components 100.I, 100.II. In the case of a functional connection of the two guide elements 110.11, 110.22, the second assembled sub - component 100.II, more precisely the second shielding housing part 110.2, enters the final assembly state through a guide path f that is axially oriented in the direction towards the coupling side A, as Figure 1b already shown.

[0052] In the initial assembly state, there is still a clearance distance x between the top surface 11 and the end of the press - fit pin 120. By continuing to join along the guide path f, the end of the press - fit pin 120.a reaches the corresponding recess 15 in the circuit carrier 10 due to the precisely positioned orientation by the guide elements 110.11, 110.22.

[0053] The guide elements 110.11, 110.22 can be designed in a variety of ways in terms of structure. Only by way of example, in an embodiment, the outer peripheral surface of the first shielding housing part 110.1 and the inner peripheral surface of the second shielding housing part 110.2 are shape - adapted to each other, in particular by a clearance adaptation or a transition adaptation, such that they are joined to each other in a sleeve - like manner. Here, also only one wall section of the second shielding housing part 110.2 can be inserted as the guide element 110.22 into the first shielding housing part 110.1, for example in the form of two oppositely arranged wall - connecting pieces, for example in Figure 1b and Figure 2cas seen therein. Preferably, they are constructed spatially in the connection region 110.12 such that they completely cover, in particular, the small recesses that may also be constructed there. By means of the guiding elements 110.11, 110.22 described in this way, a conductive abutment contact line or contact surface 115 is formed at least before or during the end state of assembly. Alternatively, this embodiment can also be designed vice versa, such that the first shielding housing part 110.1 is inserted sleeve-like into the second shielding housing part 110.2, with other features being similar.

[0054] Furthermore, a connection region 110.12 in the form of a form-fit connection, force-transmitting connection or material connection is formed at the latest in the end state of assembly. A simple feasible solution is shown in the form of a snap connection.

[0055] Generally, an electronic component 200 comprising a set of a plurality of plugs 100 can also be constructed. In this case, the first assembly sub-component 100.1 is constructed as Figure 3a described. Depending on the number of plugs 100 comprised, the first assembly sub-component has a corresponding number of first shielding housing parts 110.1, which are each connected individually to the circuit carrier 10 in the manner already described. Alternatively, all or part of the shielding housing parts 100.1 can also be integrally constructed in a common shielding element 110.x. Thus, when positioning the shielding element 110.x, all or part of the integrally constructed first shielding housing parts 100.1 are simultaneously oriented and connected in the correct position. This common shielding element 110.x has an end face 110.x1 facing the circuit carrier 10, which end face has an outer boundary profile 110.x2. The shielding element 110.x is then connected to the circuit carrier 10 without a gap along the boundary profile 110.x2.

[0056] Figure 3b A plurality of plugs 100 are shown in a state still before the start state of assembly for forming the joining of the electronic component 200. The second assembly sub-component 100.II furthermore includes a knife bar 60, in which at least a plurality of plugs 100 are received in addition to the associated first shielding housing part 110.1. Furthermore, other circuit elements 121 can also be part of the knife bar 60. In particular, the second assembly sub-component 100.II can also include a positioning and / or orientation plate 70, by means of which, for example, other circuit elements 121 and / or the second shielding housing part 110.2 can be positioned precisely in place in order to join with the first assembly sub-component 100.I. The two assembly sub-components 100.I, 100.II are joined in the manner already described, with the difference that a plurality of plugs 100 are joined simultaneously to form the electronic component 200.

[0057] The first shielding housing part 110.1 and / or the common shielding element 110.x are for example configured as formed sheet metal parts, in particular as stamped and bent parts or laser cut parts. The second shielding housing part 110.2 is configured as a die-cast molded part, in particular made of zinc, zinc alloy, aluminum or aluminum alloy.
