A plug end (PE) (3) makes an electrically conductive link with the PIE as one piece with a clearance from the PIE in a lengthwise direction (LR). The PE forms a plug-in contact. Independent claims are also included for the following: (A) A multipoint plug/multi-gang for connecting a plug to a printed circuit board with a printed circuit board press-in adapter and (B) a printed circuit board layout with a printed circuit board press-in adapter inserted in a hole in a printed circuit board.

Description

  • The The invention relates to a printed circuit board Einpressadapter for electrical Connection of at least one plug to a printed circuit board, with a press-fitting, on which at least one electrically conductive press-in pin is provided, and with one with the press-fitting electrically conductive as well as in one piece connected and in a longitudinal direction spaced from the press-fitting end of the plug, which has a plug contact formed.
  • PCB Einpressadapter of the type mentioned are known from the prior art and are used to connect a plug solderless with a circuit board. For this purpose, the press-fit pin of the printed circuit board press-in adapter is pressed into an opening in the printed circuit board, for example into a bore or socket, whereby the printed circuit board press-in adapter electrically connects to the printed circuit board. Subsequently, the plug can be plugged onto the plug end of the PCB Einpressadapters, so that the electrical connection between the plug and the circuit board is closed. Known PCB Einpressadapter are for example in the DE 10 349 584 A1 , of the DE 19 609 425 A1 and the DE 10 045 233 A1 described.
  • By the use of the well-known PCB-Einpressadapter instead from solder adapters, soldered to the circuit board could, the necessary installation effort be significantly reduced because the press connection with the circuit board faster and easier to produce than a solder joint.
  • Several PCB insertion adapter can in a housing, the e.g. made of a plastic, to a so-called Knife strip be installed, which forms a multipolar plug. The Male connector is the connector for connector and PCB. Male connectors are used e.g. used in the automotive sector where they e.g. in the engine compartment of a motor vehicle, strong temperature fluctuations can be exposed. Because the different materials of the PCB-Einpressadapter, the PCB, the plug and the male connector housing different Coefficient of linear expansion can have In the case of temperature fluctuations, there may be tension between the parts come. These voltages can cause that the press connections between the circuit board and the Loosen PCB insert adapters or solve. So can disorders electrical connections, such as loose contacts, arise.
  • Of the Invention is therefore the object of the invention over the Prior art to provide improved printed circuit board press-fit adapter, with the one opposite Temperature fluctuations more reliable electrical connection with a printed circuit board can be produced.
  • These Task is inventively characterized solved, that between the press-fitting and the plug end a weakening area is formed, whose elasticity relative to a longitudinal direction acting longitudinal force bigger is as the elasticities the press-in and plug end against this longitudinal force.
  • These constructively surprising simple solution has the advantage of having a on the PCB-Einpressadapter acting longitudinal force, e.g. by a change in length caused by a temperature change, the weakening area elastically deformed, rather than a press connection of the injection pin to negatively influence with a printed circuit board.
  • The from the weakening area of the PCB-Einpressadapters balanced longitudinal force can both a compressive force, e.g. due to a temperature increase, as well as a tensile force, e.g. caused by a cooling down, be. The invention, in a Printed circuit board press-fitted PCB Einpressadapter can compared to the state the technology higher, be exposed to repetitive temperature changes without the press connection loosens with the circuit board. So can the Printed circuit board insertion adapter according to the invention For example, be used in the engine compartment of a motor vehicle.
  • Of the Printed circuit board insertion adapter according to the invention can by different, independent, each for themselves advantageous Refinements will be further developed. On these configurations and the advantages associated with each of the embodiments briefly explained below.
  • So can the weakening area at least in sections have a meandering course to the elasticity of the weakening area across from the elasticity to increase the adapter ends and easy to manufacture the PCB Einpressadapter. Of the meander can in particular transversely to the longitudinal direction of the PCB insert adapter run and lie in the adapter level.
  • Of the weakening region can in an adapter level with the mating end and the press-fitting be formed, whereby the PCB-Einpressadapter particularly economical e.g. can be made of a metal sheet. In addition, can the press-fit adapter saves space thanks to its low thickness become.
  • Around the elasticity the weakening range continue to increase can be a cross-sectional area of the weakening area be at least partially formed smaller than the cross-sectional areas of the Pressing and plug end. The weakening range can be at least partially elastic as one in the longitudinal direction deformable spring element, e.g. as a bending or leaf spring, formed be.
  • Of the weakening region may be made of a material whose elasticity is at least is larger in sections than the materials of the press-fit end and the plug end. This has the advantage of being solely due to different materials and without shape changes the higher elasticity of the weakened area is reached. For example, you can the elasticities the press-in and the plug end by heat treatments against the elasticity the weakening range be reduced.
  • Around Press in the printed circuit board press-fit adapter in the longitudinal direction to be able to and a press-in force in the longitudinal direction preferably to transfer directly to the press-fit pin, For example, the board press-fit adapter may be associated with the plug end stop surface have, to which the press-fitting associated counter-attack surface against a in the longitudinal direction supporting acting pressure force is trained.
  • Further can the stop surface or the counter-attack surface be formed on at least one Hubbegrenzungsmittel, the one Compression of the weakening area limited in the longitudinal direction. It's going to be too big Deformation of the weakened area in the longitudinal direction, through which the press-fit adapter e.g. can buckle, prevented. The power flow from the plug end to the press-in end is in a load position, when the holding surface at the counterhold area supports, over that Hubbegrentzungsmittel passed. The stroke limiting means forms thus in the load position a bypass for the power flow.
  • In an advantageous development, the stop surface and the counter-attack surface across to the longitudinal direction be formed substantially parallel to each other. That's how it can be the two surfaces at least linear support each other and when pressing in, the press-in force is achieved via several interpolation points transferred from the plug end to the press-in.
  • The Number of trained by the weakening range meanders can also be equal to the number of stop surfaces or the number of Gegenanschlagflächen be, so that per meander loop a stop surface at a counter stop surface support can. So the press-in force can be transferred very well, because the deformation every meandering loop is limited. It is advantageous that the press-in force from the plug end evenly transferred the press-in can be, especially when mounting a PCB-Einpressadapters important with several press-fit pins. When pressing a For example, circuit board press-fit adapters with two press-fit pins transfer about 200 N from the end of the plug evenly to the press-in end so that both press-fit pins are pressed in the same way.
  • Further, on the press-in pin transversely to the longitudinal direction outwardly projecting and transversely to the longitudinal direction elastically compressible clamping portions may be formed, so that by compressing an outwardly acting clamping force can be generated. This has the advantage that with the so-developed injection molding a Längspressverband can be made with a printed circuit board in which the parts to be joined with respect to conventional press dressings larger tolerances can be formed because the clamping portions can compensate for the larger tolerances. The training of clamping sections is also in the DE 10 349 584 A1 , of the DE 19 609 425 A1 and the DE 10 045 233 A1 to which reference is hereby incorporated by reference. For easier installation of the press-in pin, chamfers or chamfers may be formed on the clamping sections in a press-fitting direction at the front. In the manufacture of the PCB Einpressadapters the clamping portions can be formed for example by embossing.
  • Around the printed circuit board press-in adapter according to the invention firmly in a housing or another holding body to be able to order may be a holding portion between the press-fitting end and the plug end with outward above anchoring bodies be provided. Thus, the printed circuit board press-in adapter according to the invention for example, in an opening a holding body, e.g. a housing a male connector. The anchoring bodies engage in this the holding body and thus prevent slipping out of the PCB Einpressadapters in the longitudinal direction. The holding body Alternatively, in an injection molding directly to the holding section be splashed around the PCB Einpressadapter. this has the advantage that the PCB-Einpressadapter firmly with the Holding body connected is and no separate mounting of the PCB-Einpressadapters in the holding body is necessary.
  • The invention relates in addition to the printed circuit board Einpressadaptern described above and de ren configurations also a male connector for connecting a connector to a printed circuit board, with a housing and with at least one printed circuit board Einpressadapter which is disposed between a press-in end and a plug end in the housing. In order to provide a male connector with which a reliable electrical connection can be made even with temperature fluctuations, the printed circuit board press-in adapters according to the invention are designed according to one of the embodiments described above.
  • Next the above-described male connector and the PCB Einpressadaptern The invention also relates to a printed circuit board assembly with at least a printed circuit board press-fit adapter pressed into a hole in a printed circuit board. To provide a printed circuit board arrangement, even with temperature fluctuations reliable can be connected to a plug, is the connection adapter According to the invention according to a the embodiments described above educated.
  • In An advantageous development of the male connector or the printed circuit board assembly can the PCB Einpressadapter Einpressende against the casing or between the plug end and the weakened area with respect to the printed circuit board be fixed, allowing a plug safely and without affecting the Press connection can be plugged onto the plug end.
  • Further For example, the PCB insert adapter may have a first operating position at a first operating temperature and a second, from the first different operating position in a second, from the first have different operating temperature and can the weakening range in the second operating position relative to the first operating position deformed at substantially mechanically undeformed remaining PCB-Einpressadapter be. In this case, the PCB-Einpressadapter of the first Operating position in the second operating position repeatedly designed to be reconfigurable. This has the advantage that length changes through compensated for the temperature fluctuations of the weakening range become.
  • in the The invention will now be described by way of example with reference to the accompanying drawings explained. The different characteristics can independent be combined from each other as above with the individual advantageous Embodiments has already been explained.
  • It demonstrate:
  • 1 a schematic top and side view of a first exemplary embodiment of a printed circuit board Einpressadapters according to the invention;
  • 2 a schematic top and side view of a second exemplary embodiment of a printed circuit board Einpressadapters according to the invention;
  • 3 a schematic representation of a male connector and a circuit board according to the invention in several views.
  • First, the general structure of a printed circuit board Einpressadapters according to the invention 1 regarding 1 and the exemplary embodiment illustrated therein.
  • The printed circuit board press-in adapter according to the invention 1 includes a press fitting 2 as well as a plug end 3 between which a holding section 4 and a weakening area 5 are formed.
  • The plug end 3 is as a running in an adapter plane AE flat plug with a plug shank 6 and a plug nose 7 educated. The plug shank 6 points in the in 1 embodiment illustrated an essentially rectangular cross-section and extends in the longitudinal direction LR substantially straight. The plug nose 7 closes to the plug shank 6 and forms in the longitudinal direction LR the one end of the printed circuit board Einpressadapters 1 out. The plug nose 7 has insertion bevels 8th on, through which the cross-section of the PCB-Einpressadapters 1 in the longitudinal direction LR up to a tip 9 reduced.
  • The plug end 3 of the PCB insert adapter 1 forms a standardized plug-in contact, on a standard mating connector (not shown) can be plugged. The mating connector can be connected, for example, with a wire of a cable. Through the plug nose 7 with the insertion bevels 8th is a threading of the mating connector and thus a simple mating possible. The mating connector is in a plug-in direction E, which extends substantially parallel to the longitudinal direction LR of the PCB Einpressadapters on the plug end 3 attachable.
  • The plug end 3 as well as the entire PCB-Einpressadapter 1 are punched out of a highly electrically conductive metallic material, for example of a Kupferknetlegierungsblech. In addition, a surface coating of a likewise metallic conductive material, such as tin, be applied. The on the plug end 3 attachable mating connector is also made of electrically conductive material Herge and after plugging electrically conductive to the printed circuit board ten-Einpressadapter 1 connected.
  • The holding section 4 joins in the longitudinal direction LR at the of the plug nose 7 opposite side in one piece to the plug end 3 at. Like the plug shank 6 also has the holding section 4 a substantially rectangular cross section, whose width B2 relative to the width B1 of the plug shank 6 is enlarged. The thickness D of the holding portion 4 is opposite to the plug shank 6 unchanged. The holding section 4 is to the plug shank 6 centered so that the holding section 4 at the opposite sides in the direction of the width B2 to the outside over the plug shank 6 protrudes. So are two to the plug shank 6 essentially right-angled steps 10 educated. Furthermore, the holding section 4 a plurality of outwardly projecting, wedge or sawtooth-shaped anchoring body 11 on. In the longitudinal direction of the steps 10 opposite the holding section widened 4 with two more levels 12 on a width B3.
  • When pressing into the circuit board is the step 10 as a counterhold for the press tool. The holding section 4 may be for fastening in a corresponding opening of a holding means, for example the housing 23 a male connector 22 , be plugged. Through the stage 12 the insertion movement is limited relative to the holding body. Through the anchoring bodies 11 , which are formed as barbs, a relative movement between the PCB-Einpressadapter 1 and the holding body against the insertion direction E 'and thus prevents slipping out of the holding body.
  • The weakening area 5 closes in one piece to the holding section 4 and is in the longitudinal direction LR opposite to the plug shank 6 arranged. At the in 1 illustrated embodiment of the circuit board press-fit adapter according to the invention 1 indicates the area of weakness 5 a punched meander bridge 13 on. The S-shaped meander bridge 13 connects the holding section 4 with the press-in end 2 , Since its width B4 is smaller than the widths B1, B2, B3, the cross-sectional area of the weakened area is 5 smaller than the end of the plug 3 and holding section 4 , In cross-section is the meander bridge 13 formed substantially rectangular and has one with the press-fitting 2 and the holding section 4 essentially the same thickness D. At the in 1 illustrated embodiment, the meandering web runs 13 in two meander loops 14a and 14b , The Mäandersteg 13 is at its ends outside the respective center in the direction of the width B of the holding portion 4 and the press-fitting 2 tethered, but on opposite sides.
  • Due to the smaller cross-sectional area is the elasticity of the meander bridge 13 compared to a longitudinal force K dimensioned larger than the elasticity of the remaining areas of the PCB-Einpressadapters 1 ,
  • At the Mäandersteg 13 of the weakening area 5 are several, in pairs opposite Hubbegrenzungsmittel 15 formed, on which a stop surface 16 or a counter-attack surface 17 is trained. Here are the stop surfaces 16 at the in 1 illustrated embodiment the plug end 3 and the counter-attack surfaces 17 the press-in 2 assigned. Between the stop surfaces 16 and the counter-attack surfaces 17 is at the in 1 illustrated embodiment formed in a rest position without force an air gap with the distance A. Alternatively, they can touch each other in the rest position. In the production of in 1 illustrated embodiment, the Hubbegrenzungsmittel 15 one-piece with the Mäandersteg 13 , for example stamped out of a metal sheet, and then embossed. The stroke limitation means 15 are in 1 each aligned inclined to the longitudinal direction outwards, but may alternatively be arranged parallel to the longitudinal direction LR.
  • The Mäandersteg 13 is formed as an elastic bending spring or leaf spring, which is elastically deformable by an externally applied force or a bending moment generated by the force. So is the in 1 exemplified PCB Einpressadapter 1 , which is shown in a rest position without external force influence, can be converted by a longitudinal force L in a load position. In the load position is the weakening range 5 deformed towards the resting position and the Mäandersteg 13 elastically deflected.
  • Under the influence of a longitudinal force K, from the plug end 3 in the direction of the press-in end 2 runs and is greater than the spring force of the weakened area 5 is, is at a fixed Einpressende 2 the weakening area 5 compressed so that the distance A between the stops 15 decreases until the stop surface 16 the counter-attack surface 17 touched and supported on it. To the longitudinal force K, which is applied for example for pressing the PCB Einpressadapters, from the stop surface 16 good on the counter-attack surface 17 To transfer, are the two surfaces 16 . 17 formed transversely to the longitudinal direction substantially parallel to each other. As a result, touch the stop surface 16 and the counter-attack surface 17 in 1 under the influence of the longitudinal force K substantially linear. The stroke limitation means 15 can each be provided at its end with a semicircular radius. The influence of force when pressing in the conductor Plate-Einpressadapters is described below with reference to the 3 described in more detail.
  • The press-in end 2 joins the weakening area 5 in the longitudinal direction L from the holding section 4 opposite. At the in 1 illustrated embodiment of the circuit board press-fit adapter according to the invention 1 is the press-in 2 U-shaped with two parallel injection pins 18 educated. Because the two press-fit pins 18 are formed substantially the same, in the following only one of the press-fit 18 described.
  • At the press-in pin 18 are transverse to the longitudinal direction LR outwardly projecting clamping portions 19 educated. The clamping sections 19 protrude beyond the otherwise uniform thickness D and the adapter plane AE of the PCB Einpressadapters 1 on both sides and have a greater thickness D 'on. The clamping sections 19 go in the longitudinal direction L laterally with insertion bevels 20 from the thickness D to the thickness D 'via. On the longitudinal direction LR of the holding section 4 opposite end of the press-in pin runs 18 with further insertion bevels 21 pointed to.
  • The clamping sections 19 of the injection pin 18 are formed elastically compressible transversely to the longitudinal direction. As a result of the compression, a clamping force or restoring force K 'acting essentially transversely to the longitudinal direction is generated. For example, when pressing the press-fit pin 18 into an opening with a width between D and D 'are the clamping portions 19 compressed and the clamping force K 'holds the press-in pin 18 non-positively in this opening. An embodiment of the clamping sections 19 is for example in the DE 10 349 584 A1 , of the DE 19 609 425 A1 or the DE 10 045 233 A1 described.
  • Due to the elastically deformable clamping sections 19 the press-in pin can be pressed into openings with a relatively large tolerance range between D and D 'because the clamping sections 19 compensate for this tolerance during pressing. Due to the large tolerance range, the production costs of the press federation can be reduced.
  • 2 shows a further embodiment of the printed circuit board insertion adapter according to the invention 1 , For the sake of brevity, hereinafter only the differences from the embodiment in FIG 1 received. Identical parts are provided with the same reference numerals.
  • In the PCB insert adapter 1 in 2 has the holding section 4 in contrast to 1 no anchoring bodies 11 but is uniform with the plug shank 6 without the step 10 formed with the same width B1. With the stage 12 expands the holding section 4 in 2 to the width B5, which is greater than the width B3 of the embodiment in FIG 1 is.
  • The holding section 4 the embodiment in 2 is particularly suitable, for example, to be encapsulated in the production of a male connector by injection molding of a housing. As such a bandage between the holding section 4 and an overmolded plastic is formed by cohesion, are not anchoring body 11 necessary. For better anchoring with the housing, an additional hole can be provided in the middle of the holding section.
  • At the in 2 illustrated embodiment, the pairwise opposite Hubbegrenzungsmittel 15 of the PCB insert adapter 1 aligned with each other, formed parallel to the longitudinal direction LR. The stop surfaces 16 and the counter-attack surfaces 17 are in 2 formed parallel and substantially e ben transversely to the longitudinal direction, so that they are in a load position, under the influence of a longitudinal force K compressed surface contact.
  • The distance A 'between the stop surfaces 16 and the counter-attack surfaces 17 in the rest position is smaller than the distance A in the embodiment in FIG 2 , Alternatively, the distances A, A 'in the embodiment in 1 already be in the rest position equal to zero.
  • Unlike the in 1 illustrated embodiment, wherein the press-fit pins 18 have a substantially constant width B6, stand in the embodiment in 2 the clamping sections 19 with a width B7 on both sides across the width B6. Openings into which the press-fit pins 18 out 2 are pressable, have a width between B6 and B7.
  • Since the clamping sections 19 in the embodiment in 2 protrude beyond the width B6, is when compressing the clamping portions 19 generates a clamping force K "substantially orthogonal to the clamping force K 'of the embodiment in FIG 1 runs. In contrast to the embodiment in 1 protrude the clamping sections 19 in 2 not above the thickness D before.
  • 3 shows an exemplary embodiment of a male connector according to the invention 22 , in which the printed circuit board press-in adapter according to the invention 1 out 1 is installed.
  • The male connector 22 includes a housing 23 , for example, from a plastic herge is is. In the case 23 Through openings (not shown) are formed, in each of which a printed circuit board press-in adapter according to the invention 1 with the holding section 4 to the stage 12 is plugged in. By the in 1 illustrated anchoring body 11 and through the stage 12 becomes a relative movement between the housing 23 and the PCB press-fit adapters 1 prevented in the installed state.
  • 3 further shows a circuit board according to the invention 24 in which the PCB-Einpressadapter 1 out 1 are pressed.
  • In the following, the assembly of a printed circuit board press-fit adapter according to the invention will be described briefly 1 in the case 23 and in the circuit board 24 with reference to the 1 to 3 described.
  • First, the circuit board press-in adapter 1 in a plug-in direction E 'in the passage opening (not shown) of the housing 23 plugged in until the stage 12 to the housing 23 strikes. The anchoring bodies 11 press in when plugging into the wall of the passage opening, so that they are connected to the housing 23 are engaged and slipping out of the PCB Einpressadapters 1 prevent against the insertion direction E '. Alternatively, the housing 23 also by injection molding around the holding section 4 of the PCB insert adapter 1 be splashed around.
  • For connecting the PCB insertion adapter 1 with the circuit board 24 become the press-fit pins 18 by means of a pressing force P in holes or sleeves in the circuit board 24 are formed, pressed. According to the embodiments of the press-fit adapter 1 of the 1 or 2 , the holes or sleeves have an inside diameter between D and D 'or between B6 and B7. When pressing in the two press-fit pins 18 in the holes of the circuit board 24 with about 200 N in a plug-in direction E, the clamping portions 19 compressed transversely to the insertion direction E. The compressed after pressing clamping sections 19 generate a clamping force K 'and K'', respectively, the PCB Einpressadapter 1 non-positively and electrically conductive with the circuit board 24 combines.
  • When the pressing force P when pressing the PCB Einpressadapters 1 in the circuit board 24 at the stage 10 attacks, it must go beyond the weakening range 5 on the press-fit pins 18 be transmitted. This is the weakening range 5 compressed in the longitudinal direction LR, because the insertion force P is greater than the spring force of the meandering web 13 is. The weakening area 5 is compressed by the insertion force P until the stop surfaces 16 on the counter-attack surfaces 17 support and the pressing force P on the press-fit pins 18 exceeds and presses them in.
  • The printed circuit board press-fit adapter according to the invention has the advantage that occurring stresses, eg caused by temperature changes, can be compensated in the installed state. When installed, as in 3 shown, the position of the housing 23 to the circuit board 24 be structurally fixed. Due to a change in temperature, the printed circuit board press-in adapter expands 1 , the circuit board 24 or the housing 23 by different coefficients of linear expansion relative to each other different or contract, so that tensions arise. When printed circuit board insertion adapter according to the invention 1 the weakened area is compressed or pulled apart by the stresses. So no longitudinal force on the press-in pin 18 transmitted, resulting in a relative movement between the circuit board 24 and the press-fit pin 18 lead and weaken the Press Association. A repeated relative movement between the press-in pin 18 and the circuit board 24 after pressing is undesirable because it can loosen the press connection and can lead to loose contacts.
  • In the installed state of the printed circuit board insertion adapter 1 the distance A, A 'between the abutment surfaces 16 and the counter-attack surfaces 17 also be zero. This contact of the stop and counter stop surfaces 16 . 17 can be designed or provided by a displacement of the plug end 3 to the press-in 2 be justified in the installed state. In this state, therefore, no compression of the weakened area 5 in the longitudinal direction LR possible and a longitudinal force K leads to a re-pressing, ie a relative movement of the press-fit pins 18 to the circuit board 24 , When the circuit board press-fit adapter 1 then cools again and contracts, becomes the weakening area 5 pulled apart by a tensile force Z and there is a gap between the stop surfaces 16 and the counter-attack surfaces 17 , In the printed circuit board press-in adapter according to the invention 1 Thus, only a repressing of the press-fit pins 18 to the circuit board 24 occur in the insertion direction E. This pressing in one direction is for the press connection with the circuit board 24 harmless, because it can occur only a few times and the clamping force K ', K''of the clamping sections 19 is influenced only slightly. A press-fit stronger debilitating reciprocating motion occurs with the circuit board press-in adapter according to the invention 1 not up.
