ELECTRICAL PLUG MODULE AND METHOD FOR MANUFACTURING

Description

[0001] The invention relates to an electrical connector module with a printed circuit board according to the preamble of claim 1 and to an associated manufacturing method according to the preamble of claim 12.

[0002] Printed circuit boards and circuit boards for electronic connector modules are known. Their manufacture utilizes electrical connectors with interlocking sockets and pins, which are electrically bonded or, in particular, soldered to the circuit board. The sockets and pins used for this purpose are metallic elements whose solder pads have certain tolerances, making precise soldering or bonding difficult and requiring time-consuming adjustments and alignment. The more solder pads a connector has, the more problematic it becomes to position all of them at the intended connection point when attaching them to the circuit board.In the case of connectors in the form of surface-mountable components, a particular disadvantage arises in that the intended position of the outer protective or mounting sleeve often also exhibits tolerance-related deviations, thus further increasing the overall deviation of a single or a group of solder terminal elements.

[0003] As already proposed by EP 1 861 898 A1, an improvement can be achieved if the plug contact parts are held and guided in a floating manner within the respective insulating or mounting body; however, this does not directly correct the tolerance-related deviation. Therefore, EP 2 639 894 A1 proposes a further solution: to arrange the solder terminal elements on a tolerance compensation piece, which projects radially and is a horizontally deformable sheet metal component located at the end of the socket-plug connector. While such a tolerance compensation piece can facilitate positioning, the problem remains that all solder terminal elements must be brought into a target position before soldering, and the radially projecting tolerance compensation piece increases the radial deviation.

[0004] From DE 90 13 456 U1, an electronic circuit board with holes and adjacent solder connection areas is known, wherein a conductor track is arranged in each solder connection area, the conductor track transitioning into the solder connection area. The adjacent solder connection area of ​​a hole is, in particular, designed as a ring or ring around the hole. A guide pin with a contact and clamping pin is inserted into a hole.

[0005] Furthermore, US 2001 / 025964 A1 discloses a comparable printed circuit board which has both holes with adjacent solder connection areas and solder connection areas without such holes. In this case, a flat contact and clamping pin is mounted on the underside of the solder connection area. The contact and clamping pin comprises a connector element into or on which a complementary connector element can be attached.

[0006] DE 10 2007 039064 A1 discloses an electrical device for use as a control unit for a pump. The device has a connector with two connecting pins and a contact carrier that holds the connecting pins.

[0007] Finally, US 6 353 191 B1 discloses a Ball Grid Array (BGA) that is soldered onto a printed circuit board via a multitude of solder pins inserted into the base element.

[0008] Starting from the described state of the art, the invention is based on the objective of proposing a possibility for easier attachment of connectors to printed circuit boards and improvement of the positioning of solder connection elements.

[0009] This problem is solved according to the invention by an electronic plug module with the features of claim 1 and by an associated manufacturing method with the features of claim 12. The respective dependent claims contain the associated advantageous embodiments.

[0010] In this document, the terms "printed circuit board" and "circuit board" are used synonymously, as are the terms "sleeve" or "socket".

[0011] The electronic connector module according to the invention comprises a one- or multi-part housing and at least one external connector, which is attached to the housing by means of a protective and mounting sleeve or directly. The external connector contains at least one electrically conductive main pin, which is electrically connected to a printed circuit board (PCB). The PCB comprises a mounting plate and one or more contact and clamping pins and is configured according to one of the following embodiments or a combination thereof.

[0012] According to the invention, the printed circuit board is an electronic circuit board or circuit board comprising a backing plate made of an electrically non-conductive material known in the prior art, as well as electrical conductors and one or more electronic components. The backing plate or support element has The soldering connection area has at least one bore, with at least one adjacent solder connection area, and / or at least one solder connection area without a bore, wherein at least one conductor leads to the solder connection area and this conductor transitions into the solder connection area. If the solder connection area is arranged adjacent to a bore, it is designed, in particular, as an annular or ring-shaped solder connection area around the bore. Furthermore, a guide pin of a contact and clamping pin is inserted into or placed on the bore and on the associated solder connection area, or a contact and clamping pin without a guide pin is placed flat on the solder connection area.

[0013] The contact and clamping pin comprises a connector element in or on which a complementary connector counterpart of the main pin, such as an end pin or end sleeve of the main pin of the external connector, is attached. Furthermore, the contact and clamping pin is soldered to at least one partial surface of the respective solder connection area.

[0014] In an advantageous embodiment, the contact and clamping pin has at one end a guide pin which is at least partially inserted into the bore of the support plate and / or a flat underside which rests fully on the solder connection area.

[0015] In this case, the plug element at the opposite end is designed as a clamping element, in particular as a clamping socket, for receiving and connecting to a main pin or its end pin.

[0016] The major advantage of such a circuit board is that the potential contact points between the board and possible external connectors are pre-prepared and very easy to use, allowing for the simple and precise manufacturing of all subsequent modules in any variety of configurations. Furthermore, this contact and clamping pin, as the primary standard connector to the circuit board, improves the connection to all subsequent connections.

[0017] In an advantageous embodiment, the contact and clamping pin is only partially received in the bore at one end, and the other end, which is designed as a clamping bushing for receiving a main pin or its end pin, the free connecting end, is arranged above the support plate.

[0018] To ensure a secure fit and optimal fastening or soldering, one embodiment provides that the outer diameter and / or the shadowed area of ​​the clamping socket is larger than the outer diameter and / or the shadowed area of ​​the guide pin. This creates a soldering and contact surface below the clamping socket, against which the contact and clamping pin rests and is soldered to the mounting plate. This precise, guided positioning of the contact and clamping pins in their respective bores and the soldering of the edge areas ensures optimal alignment for the soldering step, thereby improving the overall quality of the printed circuit board (PCB).Tolerance variations of the main pins or their solder lugs no longer play a role in the optimal electrical connection to the circuit board, and the still slight horizontal positional deviations of the main pins are reliably compensated by the clamping sleeves held in the circuit board.

[0019] Advantageously, the inner surface of a clamping sleeve has at least one inwardly projecting cutting or friction element, so that a force-fit and, ideally, also a material connection is created between the clamping sleeve and the main pin. A cutting or scraping ring that runs almost completely around the sleeve, except for minor interruptions, is particularly advantageous. These interruptions occur, for example, when the clamping sleeve has one or more slots open towards the free end, allowing for slight, resilient deformation of the clamping sleeve without damaging it. In this context, the term "clamping sleeve" is used to refer to any suitable passive clamping geometry, such as two clamping jaws.

[0020] In a further, improved embodiment, a sealing element, such as a sealing frame or ring in particular, is arranged around individual clamping sleeves and / or a group of two or more clamping sleeves, wherein the sealing element is advantageously glued onto the support plate.

[0021] Another improved embodiment provides that at least one contact and clamping pin, in particular a group of contact and clamping pins, is part of a connecting element and is firmly connected to it, in particular by force-fit and / or form-fit connection, welding, casting, or bonding. Here, the connecting element comprises an electrically non-conductive sealing material or is largely formed from this sealing material as a monolithic base or main body. The sealing material encloses the at least one contact and clamping pin or the group of contact and clamping pins, whereby a single contact and clamping pin or a group of contact and clamping pins are arranged in an opening, bore, or channel in the sealing material and are enclosed by this sealing material.The contact and clamping pins of a group of contact and clamping pins are determined in particular by the fact that these contact and clamping pins are all functionally assigned to a single external connector to be connected, and wherein the number of contact and clamping pins advantageously corresponds to the number of maximum possible connection possibilities, i.e. in the case of a complete occupancy of all electrical connection possibilities of the external connector with the circuit board.

[0022] An improved embodiment provides that the position and orientation of the contact and clamping pins in the connecting element is such that the contact and clamping pins have bearing surfaces, in particular below the plug-in sleeves, which act as soldering surfaces, and all bearing surfaces of the contact and clamping pins of a connecting element form a common contact and bearing surface with the underside of the respective connecting element, here the sealing material.

[0023] The connecting element described above is advantageously attached to the mounting plate, in particular by gluing, adhering, snapping and / or clamping, in addition to the soldered connections of the contact and clamping pins to the circuit board.

[0024] In one embodiment of the connector module, the module has at least one interior space between the mounting plate and the housing, which is at least partially filled with a casting material that is electrically non-conductive, such as an acrylic resin. Depending on the interactions with the surrounding components and elements, all common materials can be used as the casting material. Advantageously, the protective and mounting sleeve or the outer connector has at least one inner stop edge that rests against an inner surface of the housing and seals it. An improvement is to provide a seal or sealing material in the area of ​​the stop edge and the contact surface with the inner surface.

[0025] The manufacturing process for plug modules according to the invention, based on one or more of the preceding embodiments, includes in particular the following steps. Provision of mounting plates with at least one bore and / or at least one solder connection area for a contact and clamping pin, wherein the mounting plate is generally already covered with all conductor tracks and functional modules and elements, so that the following steps advantageously represent the final manufacturing steps of the actual printed circuit board, inserting or placing at least one contact and clamping pin into the at least bore and / or the solder connection area, establishing a fastening and electrically conductive connection of the at least one contact and clamping pin or the at least one group of contact and clamping pins with the mounting plate, in particular by soldering and plugging the mounting plate or the printed circuit board onto at least one main pin of an external connector inserted and held in a housing.

[0026] In an alternative embodiment of the manufacturing process, before the mounting plate or the circuit board is attached to the at least one main pin of an external connector inserted and held in a housing, a sealing element is placed around the at least one contact and clamping pin and / or the at least one group of contact and clamping pins. In this case, the sealing element is, in particular, one that encloses each contact and clamping pin of a group of contact and clamping pins individually and, in particular, the respective group of contact and clamping pins as a whole.

[0027] In an advantageous embodiment, the at least one contact and clamping pin or the at least one group of contact and clamping pins is a component of a connecting element, which further comprises at least one sealing material having an opening, or is largely formed from such a material. In this case, one or more contact and clamping pins are arranged at least partially in at least one opening of the sealing material before the sealing material is attached to the support plate.

[0028] Here, an opening in the sealing material is understood to mean, in particular, any channel or bore that both encloses the contact and clamping pin and allows the direct insertion of a mating connector. During manufacturing, the connecting element is provided as a pre-assembled small intermediate connector with all necessary, especially the maximum, number of contact and clamping pins. It is inserted into the corresponding bores (group of bores) or placed onto the corresponding solder connection areas. The contact and clamping pins are then soldered across the contact surfaces, which can be done from the back of the mounting plate. Little to no alignment is required, which significantly speeds up the overall manufacturing process of the connector modules.

[0029] All information regarding the orientation of elements, such as "top" or "bottom," describes a position of the circuit board or connector module where an external connector can be inserted or attached vertically from above. This means the circuit board is horizontally oriented, as shown and described in the figures, and the terminal sockets of the contact and clamping pins point vertically upwards. It is immediately apparent to a person skilled in the art that such information regarding geometric orientation serves only as an exemplary description and does not imply any restriction on any final installation position or orientation.

[0030] Furthermore, the free, lower end of the main connector is primarily described as an end pin that is received in a clamping sleeve supported by the circuit board, which undoubtedly represents a very advantageous embodiment. However, it is immediately obvious to those skilled in the art that this principle can be inverted by designing the lower free end of the main connector as an end sleeve / socket and, instead of the clamping sleeve on the circuit board, providing at least one mating pin / plug that projects beyond the circuit board and is received by this end sleeve of the main pin in an analogous manner.

[0031] The invention will be explained in more detail below with reference to exemplary embodiments shown in the figures. It shows Fig. 1 the connector module in a sectional view, Fig. 2a, b, c detailed views of the circuit board as a sectional view with different embodiments of the contact and clamping pins, Fig. 3 the connector module according to Figure 1In one embodiment, Fig. 4 shows different sealing elements in a perspective view, Fig. 5a, b, c, din shows connecting elements comprising different contact and clamping pins in a perspective view, Fig. 6 a to the Figure 1 or 3 Analog connector module in an improved embodiment, Fig. 7 a schematic representation of a manufacturing process of the connector module according to Figure 1 and Fig. 8 a first manufacturing step for an embodiment of the circuit board.

[0032] For identical or similarly functioning elements of the invention, identical reference numerals are used in the figures. Furthermore, for the sake of clarity, only those reference numerals necessary for describing the respective figure are shown in the individual figures. The invention is also presented in the figures only as a schematic view to illustrate, for example, its operation, and the figures serve only to explain the fundamental principle of the invention. For the sake of clarity, it has been omitted to show all components, in particular the printed circuit board or circuit board, which is generally covered on one or both sides with a multitude of printed or soldered traces and contains a wide variety of electronic components, functional modules, etc.

[0033] The Figure 1Figure 1 shows the connector module 1 with two external connectors 3, which can be connected to a mating connector by a user as needed. The external connectors 3 are housed in a known manner within a housing 2 of the connector module 1, for which purpose they are inserted through mounting openings 19 and locked into place. The external connector 3 has a two-part construction and comprises an outer protective and mounting body 4 and an inner body 5 held within it, in which several electrically conductive main pins 6 are arranged. In the external connector 3 shown on the left, the main pins 6 are designed as contact bolts at their outer end 5.1 of the inner body 5, and in the external connector 3 shown on the left, as contact sleeves. Furthermore, a central, electrically non-conductive guide pin 7 is provided in each case. At the inner end 5.2 of the inner body 5, the main pins 6 are connected to a circuit board 8 comprising contact and clamping pins 10.These contact and clamping pins 10 are soldered into the support plate 30 of the circuit board 10, as shown below. Figure 2 will be explained in more detail later.

[0034] In an embodiment not shown, the external connector 3 is additionally fastened or secured from the outside, in particular with a union nut. Furthermore, seals can be provided between flanges of the inner body 5 or the protective and fastening body 4 and a respective mating or contact surface, which are not shown here.

[0035] In the Figure 2aAn embodiment of the circuit board 8 is shown, in which, by way of example, two contact and clamping pins 10 are guided through the mounting plate 30 by means of bores 20, which are designed as through-holes. The circuit board 8 can have other known circuit board components, conductor tracks, etc., which are not shown here. The contact and clamping pins 10 have a clamping socket 10.2 at their upper end, which faces the underside 5.2 of the inner body 5, and at their other free end, the contact and clamping pin 10 is designed as a guide pin 10.1, which is partially guided through the mounting plate 30 of the circuit board 8 and projects beyond it by a portion of its length. Below the clamping socket 10.2, at the transition to the guide pin 10.1, which has a smaller diameter, a soldering and support surface 10.3 is formed, which rests on the support plate 30 in an area that corresponds at least partially to the solder connection area 9 and is soldered to it.In the illustrated embodiment, the clamping bushing 10.2 has at least one constriction to create a clamping connection with the end pin 6.1 of the main pin 6 and furthermore at least one vertical expansion slot 10.4 to allow slight movement and deformation for clamping. In the embodiment according to... Figure 2b , an improvement in execution according to Figure 2aThe support plate 30 is not perforated with a through hole, but only has a blind or recessed hole 20.1. The free end of the contact and clamping pin 10 has a length that is slightly shorter than the depth of the recessed hole 20.1 and is inserted into it. The installation and soldering in the solder connection area 9 is analogous. This embodiment leaves the entire underside of the circuit board undisturbed and can thus be fully used, for example, for the arrangement of conductor tracks, functional elements, or other components. A resin or adhesive material (not shown) can be provided in the recessed hole 20.1 to increase its strength. Finally, [the figure shows...] Figure 2c an embodiment in which the contact and clamping pin 10 is flat below the sleeve-like plug element, so that the entire underside of the clamping sleeve 10.2 rests on and is soldered to the solder connection area 9.

[0036] In the sectional view of the Figure 3 , is a plug module 1 shown, which is analogous to that of the Figure 1Figure 2 shows two external connectors 3, which are connected to a circuit board 8 comprising contact and clamping pins 10 via these contact and clamping pins 10 by means of a plug-in sleeve connection. To protect the internal connector connections, a sealing element 11 is arranged between the lower end 5.2 of the inner body 5 and the upper surface of the support plate 30, which encloses the individual contact and clamping pins 10 and the groups of contact and clamping pins 10 from the outside. It can also be seen that a cast material 18 is introduced into the interior space 17 between the housing 2 and the support plate 30, partially filling the interior space 17. An overcut 16 is visible on the upper surface of each of the connecting elements 13, formed by the compression of the sealing material 15. The clamping sockets 10.2 terminate with their upper edge well protected from environmental influences in the center of the openings 23 of the sealing material 15.

[0037] These sealing elements can, as in Figure 4c The sealing elements 11.1 and 11.2 are shown, and may also be designed as a sealing ring 12, which encloses a group of contact and clamping pins 10 that are assigned to an external connector 3. Figures 4b and 4c show sealing elements as they are used in the connector module after Figure 3 These sealing elements were provided. During the manufacture of the connector module 1, they are either placed or glued onto the circuit board 8 before being joined with the pin ends 6.1 of the main pins 6. Alternatively, before being connected to the circuit board 8 with the openings 23, they are placed around or over the end pins 6.1 of the main pins 6 at the inner end of an outer connector 3.

[0038] In the Figure 5a-dIn the illustrated variants, the contact and clamping pins 10 and the seal constitute a connecting element 13, which is formed as a single component consisting essentially of a sealing material 15 and the contact and clamping pins 10. The contact and clamping pins 10 are suitably glued, cast, pressed, or otherwise fastened in the openings of the sealing material 15 in the adjacent holding area 15.1. Figure 5a shows the top side 13.1 of the connecting element 13 and Figure 5b The underside 13.2 of the connecting element 13, from which the free ends of the contact and clamping pins 10 protrude. In the flat version according to Figure 5a Both the clamping bushings 10.2 and the free ends (not shown) of the contact and clamping pins 10 protrude from the sealing material 15. In contrast, the contact and clamping pins 10 according to the design in the Figure 5bThe contact and clamping pin 10 is arranged in the openings of the sealing material 15 in such a way that the bearing surface 10.3 and the contact and clamping pin 10 form a closed surface with the underside 13.2. In the installed position, the underside 13.2, and thus also the bearing surfaces 10.3, rests on the support plate 30. The clamping bushings 10.2 do not protrude beyond the sealing material 15, as also shown in the Figure 6 are shown, but are located inside the vertical opening 23 of the sealing material 10 and are therefore well protected.

[0039] The Figures 5c and 5d show 30 bonded and soldered connecting elements 13 on the support plate, wherein the Figure 5c A connecting element 13 shows in which contact and clamping pins 10 are glued in the holding area 15.1, which correspond to those of the Figure 2c correspond. Regarding the connecting elements 13 of the Figure 5d is the analogous structure to Figure 5cshown, wherein the two contact and clamping pins 10 shown and held clampingly in the holding area 15.1 of the embodiment according to the Figure 2a correspond, so that the above applies analogously.

[0040] The structure according to the Figure 6 is comparable to the Figure 3 , wherein in the present case the circuit board 8 is equipped with connecting elements 13, which are analogous to the Figures 5b and 5d are constructed and arranged. The connecting elements 13 are glued to the underside of the support plate 30 and / or soldered to the contact and clamping pin 10 via the contact surfaces 10.3.

[0041] The particular advantage of this invention lies in the simple assembly of the circuit board 8 and the connector modules 1, as shown in the Figure 7 and 8 This will be briefly explained. Previously, the main pin or one or more elements of the main pin of an external connector were soldered directly to a circuit board. The sequence according to path I. of the Figure 7The carrier plate 30 is separately equipped with the contact and clamping pins 10, independent of any specific embodiment or variant of the actual connector module 1 and the external connectors 3 to be provided. As a rule, all possible solder and contact positions for external connectors 3 are occupied with contact and clamping pins 10 and soldered. Path II of Figure 7 shows, on the left, a monolithic housing 2 with openings 19 for the external connectors 3. In the following step, the different external connectors 3 are pressed in and then sealed with sealing elements 11, 12, such as for... Figure 4 described and shown.

[0042] Finally, only the mechanical assembly, a pressing together, of the circuit board 8 with the end pins 6.1 of the main pins 6 takes place. The connector socket geometry allows for tolerance compensation without any separate rework or adjustment. Furthermore, the complex alignment and holding of solder lugs is no longer necessary, and there is no need to protect components from harmful heat input during a final soldering process.

[0043] The Figure 8 shows an improved variant in which manufacturing has been further simplified by including in path I. Figure 7 Now, the sealing elements 11 and 12 are also glued onto the support plate 30 before final assembly. This step can be prepared completely independently of the final assembly.

[0044] Not shown, but in an analogous manner, a circuit board 8 is manufactured, which is connected with fasteners 13 according to the Figure 5The components are pre-assembled and prefabricated. These are also pre-glued and / or soldered onto the circuit board 30. This offers a further manufacturing advantage because the relative positions of a group of contact and clamping pins are already fixed.

[0045] This continuous plug-sleeve connection of a main pin, its end pin or sleeve into a contact and clamping pin supported by a circuit board, exhibits only slight horizontal tolerance deviations, which are effectively compensated for during insertion by the respective conical sleeves and correspondingly shaped pin heads, which usually end conically or rounded.

[0046] Different embodiments are to be distinguished here, and it is hereby suggested to the person skilled in the art to combine, reproduce or partially omit the individual elements or combinations thereof as necessary, insofar as they are not mutually exclusive. Reference symbol list
