Description

The invention relates to a press-in contact and a press-fit tool for connecting an electronic component to a printed circuit board, wherein the press-in contact of the electronic component can be pressed by the press tool into a contact opening of the printed circuit board and a method for producing a press-fit.

From the prior art, a variety of solutions are known, which relate to the design and installation of press-fit pins, which are used in connectors. For the tools used in the assembly of such press-fit pins, blade connectors or pins for connectors or power strips usually enough space is available to ensure proper pressing, for example, in a circuit board.

So be in DE 87 14 341 U1 pin-like blade connector for connectors described which are arranged on a printed circuit board in a certain pitch to each other in several rows. To ensure a tight fit of the blade connector in the circuit board, each blade connector is formed with a corresponding press-in zone. The attachment of the blade connector in the circuit board by means of a press-in tool, with which several blade connectors are pressed into the openings of the circuit board. In order to avoid skewed pressing and deformation of the plug, the blade connector is provided above its press-in zone with stop shoulders projecting laterally beyond the pin, against which the press-fit tool can engage.

Likewise, the in DE 10 2006 055 086 B3 described inserting pin for electrical contacts used in particular for connectors.
Here, the press-in pin should be designed so that it can be pressed without damaging it. For this purpose, the press-in pin has a shoulder element with the aid of which a tool can grasp the pin and can transmit a force in the longitudinal direction of the pin to it. In this case, the shoulder element may have different configurations.

In order to avoid displacements or deformations of the components in the assembly of electronic components on printed circuit boards, an accurate positioning of the press-fit or Einpressstifte to the contact openings of the circuit board is required. With correspondingly large-dimensioned electronic components special press-fit tools must be used, which take up as little space as possible. Such press tools, such as mounting combs, take the press-fit contacts or press-fit pins and perform a corresponding positioning.

An electronic component for mounting on a printed circuit board is in DE 103 03 009 A1 disclosed. This device has connecting wires with press-in contacts and should thus be electrically connected without additional adapter with contact openings alone by pressing the press-fit. The press-fit contacts are provided with a shoulder in order to transmit the press-in force and to limit the press-in depth in the contact opening.
With the help of a tool, the press-in contact is inserted into the contact opening and pressed.
In DE 103 03 009 A1 Although not discussed in more detail on the press tool and the available space. However, it is easy to imagine that an accurate positioning of the press-in contacts to the circuit board openings and a straight press-fitting along the axis of the press-fit contact is not guaranteed. It can easily lead to a misalignment of the Press fit come, whereby a proper attachment of the electronic component is not possible.
By contrast, mounting (in particular concealed) of press-contacting contacts requires precise positioning of the press-contact tips to the printed circuit board openings during the joining movement. For this purpose, currently very complex or driven by expensive technology mounting combs are used, which require a relatively large amount of space.
So will be in the not yet published DE 20 2008 012 657.6 a tool for producing a contact of an electronic component with a circuit board described in which the tool designed as a mounting comb has a sleeve-shaped guide body which receives an axially movable sliding part. Between sliding part and guide body there is a relative mobility in the axial direction. The press-fit contacts are received in serving as positioning aids grooves of the guide body or the sliding part. In this case, the press-fit contacts each have a shoulder, with which they rest against a stop of the guide body (or the sliding part) during the press-fitting process.
Due to the ever-narrower design of the electronic assemblies assembly with the described mounting comb is difficult to achieve.
Also from the publication WO 95/14315 A1 a press-in contact is known, which can be pressed with a press tool into a contact opening of the circuit board, but the guide length of the guide contour has only a small length, so that it can lead to tilting during pressing.

The object of the invention is to provide a press-in contact and a press-fit tool for connecting an electronic component to a printed circuit board, and a simple method for producing a press-fit, wherein using a cost-press tool even with a small space easy mounting of the electronic component on the circuit board is ensured at high positioning accuracy.

This object is achieved according to the features of the 1st, 8th and 13th

Claim solved.

Further embodiments show the dependent claims.

According to the invention, the press-in contact has at least one guiding area which can be received in a guide contour of the press-in tool with a maximum guide length and a maximum width, the maximum guide length being a multiple of the maximum width, so that the guide area has a high rigidity in the press-in direction (z-direction) and Flexibility in the other two directions (x / y directions) has.

Preferably, the press-in contact two (or more), spaced apart in the axial direction, shoulder elements, which are in a guide contour of the press-in tool positionally receivable. The shoulder elements are arranged between a press-fit zone of the press-fit contact and a connection piece of the electronic component on the press-fit contact.
Each shoulder element represents a cross-sectional widening of the press-fit contact corresponding to the maximum width of the guide region, which in each case has a guide surface which is in contact with the guide contour of the press-fit tool.

The shoulder elements are arranged at a distance from each other, which is formed by an intermediate piece in the form of a cross-sectional reduction, the width of which is smaller than the maximum width of the guide region. The shoulder elements may be the same or different shaped and / or dimensioned. They can be made in one piece or in several pieces with the press-in contact.

The high rigidity of the guide area in the press-in direction (z-direction) ensures the transmission of the required press-in forces. The flexibility of the guide area in the installed state in xy direction ensures the greatest possible insensitivity to vibrations, shock loads and the like. The guide area has for this purpose a flexibility ensuring cross-sectional reduction.
Preferably, each press-in contact was separated by separating interlinked press-fit contacts.

The press-in tool according to the invention accommodates a press-fit contact in at least one guide contour, which has a guide region with a maximum guide length and a maximum width, wherein the maximum guide length is a multiple of the maximum width.
The contour length of the guide contour of the press tool corresponds to at least the guide length of the press-fit. The shoulder element closest to the electronic component is located during the press-fitting process on at least one abutment of the guide contour of the press-in tool arranged transversely to the press-in direction. The guide surfaces of the two shoulder elements are during the press-in operation in the press-in direction to complementary side surfaces of the guide contours of the press tool.
The guide contour of the press-fit tool represents a cross-sectional enlargement of a guide groove provided at the end of the press-in tool. The guide contour can, however, also be arranged in an attachment which is located at the end of the press-fit tool. In this case, the attachment can be made in one piece with the press tool. But it can also be attached as a separate component to the press tool.
The guide contours are provided in inserts of the attachment part, wherein the guide contours and / or the inserts are preferably exchangeable.

The production of a press-in contact is effected according to the invention in that first the contours of the contours of the press-fit contacts are concatenated together / strung together in a band. Subsequently, the band is fed to a separation station and separated in this the chained composite at predetermined separation points to individual press-fit.

In the band, the individual contours of the press-fit contacts are connected to one another at least in the region of the guide regions, and preferably also at their opposite ends.

The separation points are preferably between two shoulder elements of a press-fit, so that forms a constriction in the form of an intermediate piece between the shoulder elements during separation, whereby the guide contours of the shoulder elements are not affected by the separation process.

In Fig. 1 an electronic component B is indicated, which represents, for example, a coil. The electronic component B here has two connecting wires / connecting pieces B1, at the free ends of each a press-in contact 1 is provided. Depending on the size and the nature of the electronic component B, the number of connecting pieces B1 and thus also the press-fit contacts 1 can vary. The press-fit contacts 1 are advantageously arranged in the axial direction of the electronic component B. However, they can be mounted at an angle to the component B as well as the connecting pieces B1. It should be noted at this point that the direction of the press-in process to be performed can be seen as the axial direction or longitudinal direction of the press-fit contact 1.
The press-fit contact 1 has a guide region 1.1, to which a press-in zone 2 and a component side connect the connection pieces B1 to the printed circuit board side. The guide region 1.1 has a maximum axial guide length a1 and a maximum width b1. In this case, the maximum guide length a1 is greater by a multiple than the maximum width b1 of the guide region 1.1 of the press-fit contact 1.
In a preferred embodiment, the guide region 1.1 consists of two shoulder elements 3, 5 spaced apart from one another in the axial direction.
The first shoulder element 3 is located at an axial distance a from the second shoulder element 5, wherein the distance a at the same time corresponds to the length of an intermediate piece 4 with a width b reduced to the width b1. The shoulder elements 3, 5 together with the intermediate piece 4, a maximum guide length a1.

In this case, the shoulder elements 3, 5 are preferably designed as approximately the same size, the maximum width b1 corresponding, cross-sectional widening of the guide portion 1.1 of the press-fit 1, which have a guide surface 3.1 and 5.1 in the axial direction. The shoulder elements 3, 5 may be manufactured in one piece with the press-fit contact 1 or produced in several pieces and are located here between the press-fit zone of the press-fit contact 1 and the connection piece B1 of the electronic component B.
However, the press-fit contact 1 could also be connected directly to the component B without the interposition of a connecting piece B1.
Between the shoulder members 3, 5 (guide portion 1.1) and the fitting B1 of each press-fit contact 1, an unspecified S-shaped bent portion is formed, so that each press-fit contact 1 can spring in two directions (indicated by the double arrows) in this Fall in the press-in direction (z-direction) and away from the plane of the press-fit contact 1 (y-direction) and at right angles thereto in the direction of the plane of the press-fit (x-direction), wherein a torsional rigidity of the press-fit contact 1 in the z-direction (press-in) ensured is. As a result, a flexibility of the component B is achieved with respect to the circuit board equipped therewith (not shown here), which ensures that vibrations and shocks are better withstood.
In addition, due to the weakening of the cross section in the guide region 1.1 by the reduced width b of the intermediate piece 4 extending between the first shoulder element 3 and the second shoulder element 5, a flexibility of the guide region in the x / y direction while ensuring the required rigidity in the z direction (at Pressing) achieved. The flexibility of the guide area in the x / y direction ensures, when installed, flexibility in the end product and the rigidity in the z direction the transmission of the required press-in force.

In Fig. 2 is a partial view of a press-in tool 6 shown in the manner of a mounting comb. The press-in tool 6 has two guide grooves 7 on, wherein in each case a guide groove 7 is provided for receiving in each case a press-fit 1. The guide grooves 7 point to the in the direction of a to be contacted circuit board L (in the FIGS. 5 to 7 shown) lying end of the press tool 6 by cross-sectional widening formed guide contours 7.1. Their contour length I corresponds approximately to the maximum guide length a1 of the press-fit contact 1. Stops 8, which extend transversely to the axial direction, delimit the guide contours 7.1 open towards the end of the press-in tool 6.
The further structural design of the press-in tool 6 is not essential to the invention here and therefore not shown.

In Fig. 3 the electronic component B is received with its press-fit contacts 1 of the press-in tool 6, wherein the component-side shoulder element 5 rests against the stops 8 of the press-fit tool 6. The adjoining the press-in zone 2 of the press-fit contact 1 shoulder element 3 is located at the end of the press-in tool 6 within the guide contour 7.1. The spaced, about their respective guide surfaces 3.1 and 5.1 with the guide contours 7.1 in contact shoulder elements 3, 5 cause a good positioning and fixing the position of the press-in contact 1 in the press tool. 6

Fig. 4 shows a further possible embodiment of the press-in tool 6. Here, the press-in tool 6 an attachment part 9, in which inserts 9.1 are in the form of the guide contours 7.1. The attachment part 9 can be made in one piece with the press-in tool 6; but it can also be attached to the press tool 6 as a separate component. In the case of additionally mounted on the original press tool 6 attachment part 9 is a simple retrofit of known Einpresswerkzeugen 6 for press-fit contacts 1, z. B. with a shoulder element 3, to Einpresswerkzeugen 6 with two shoulder elements 3, 5 possible. The inserts 9.1 are preferably provided interchangeable. In case of wear of the highly stressed

Guide contours 7.1 can be removed the old bets 9.1 and new inserts 9.1 are introduced. This offers the possibility of using more effective production methods for the press-in tool 6.

Fig. 5 shows the press-in tool 6 with the press-fit contacts 1 before the press-in process in a positioning position. In this case, the printed circuit board L with its contact openings L1 on the tips of the press-fit contacts 1, which abut with the guide surfaces 3.1 and 5.1 of the two shoulder elements 3, 5 on complementary side surfaces of the guide contours 7.1.

In Fig. 6 is the press-in tool 6 shown with the press-fit 1 at the beginning of the press-fitting. The press-fit contacts 1 are located with their tip ends in the contact openings L1 of the printed circuit board L.
Together with the voltage applied to the stop 8 shoulder element 5, both the intermediate piece 4 and the shoulder element 5 are within the guide contour 7.1 of the press tool. 6

Fig. 7 shows the press-in tool 6 with the press-fit contacts 1 at the end of the press-fitting process. The printed circuit board L rests with its press tool 6 facing side on this. The tips of the press-fit contacts 1 look out on the side of the printed circuit board L facing away from the press-in tool 6, while the press-in zones 2 of the press-fit contacts 1 are located in the contact openings L1 of the printed circuit board L. Both shoulder elements 3, 5 are as well as the intermediate piece 4 still in the guide contour 7.1 of the press tool. 6

In Fig. 8 Further possible embodiments (a) to (d) of the press-fit contact 1 according to the invention are shown, which indeed show differently designed guide regions 1.1, but in which an approximately equal ratio of maximum guide length a1 to maximum width b1 is present and which can be pressed into the contact opening L1 of the printed circuit board L with the press-in tool 6 according to the invention.

• Zur Durchführung des Einpressvorganges wird die Leiterplatte L über das Einpresswerkzeug 6 bewegt. Das elektronische Bauelement B befindet sich mit seinen Einpresskontakten 1 in den Führungskonturen 7.1 des Einpresswerkzeuges 6 entsprechend der weiter oben beschriebenen Figur 3.

Die Kontaktöffnungen L1 der Leiterplatte L werden über den Spitzen der Einpresskontakte 1 positioniert. Durch ein Aufschieben der Leiterplatte L von oben auf die von dem Einpresswerkzeug 6 gehaltenen Einpresskontakte 1 erfolgt deren Einpressen in die Kontaktöffnungen L1 der Leiterplatte L.
Nach Beendigung des Einpressvorganges wird das Einpresswerkzeug 6 zurückgefahren, d. h. es entfernt sich nach unten von der Leiterplatte L. Das elektronische Bauteil B ist mittels seiner Einpresskontakte 1 auf der Leiterplatte L befestigt.
An dieser Stelle sei angefügt, dass auch die Möglichkeit besteht, das Einpresswerkzeug 6 in Richtung der ruhenden Leiterplatte L zu bewegen und das Einpressen durch Druck auf das Einpresswerkzeug 6 durchzuführen.The attachment of the electronic component B on the circuit board L is carried out as follows:

• To carry out the press-fitting process, the printed circuit board L is moved over the press-in tool 6. The electronic component B is located with its Einpresskontakten 1 in the guide contours 7.1 of the press tool 6 according to the above-described FIG. 3 ,

The contact openings L1 of the printed circuit board L are positioned over the tips of the press-fit contacts 1. By pushing the printed circuit board L from above onto the press-fit contacts 1 held by the press-in tool 6, they are pressed into the contact holes L1 of the printed circuit board L.
After completion of the press-fitting operation, the press-in tool 6 is retracted, ie, it moves away from the printed circuit board L. The electronic component B is fastened by means of its press-fit 1 on the circuit board L.
It should be added at this point that it is also possible to move the press-in tool 6 in the direction of the stationary printed circuit board L and to carry out the pressing in by pressing on the press-in tool 6.

By compared to the state of the art newly added second shoulder element 5, which is in a distance 4 a corresponding to the intermediate piece 4 to the first shoulder element 3, there is an extended guidance of the press-fit 1 within the press tool. 6
The dimensions of the press-fit contact 1, such as. As the distance a or the guide length a1, depending on the application (but in accordance with the contour length I of the press tool 6) vary.

Due to the two spaced shoulder elements 3, 5, which during the entire Einpressvorganges within the appropriately designed

Guide contour 7.1 of the press-in tool 6 are located, can be ensured with the solution according to the invention a high positioning accuracy during the positioning and joining process. The assembly process can be carried out smoothly without jamming due to production-related form errors.
In addition, the width b present in the form of a cross-sectional reduction relative to the maximum width b1 makes it possible to link the contacts in the production process without the cutting burr after the separation (separation) of the contacts having a negative influence on the guide surfaces.

Another advantage is achieved with the inventive design flexibility of Einpresskontakte 1 during the press-fitting process and in the installed end product.

In the one in the drawings FIG. 1 to FIG. 7 1, the press-fit contact 1 has a guide area 1.1, the advantages of which extend the guide of the press-fit contact 1 within the press-fit tool 6 by two axially spaced shoulder elements 3, 5, which represent a cross-sectional widening of the guide area 1.1 with the maximum width b1.
The guide portion 1.1 can also be formed as a single shoulder element (see FIG. 8 ), which has a maximum width b1 over the entire maximum guide length a1 or at least over the majority of the guide length a1. It is important that here too, the maximum guide length a1 is greater by a multiple than the maximum width b1.

In the first representation (a) from the left according to FIG. 8 For example, the press-fit contact with a double shoulder in the guide area was shown according to the examples described above. Due to the constriction between the two shoulders, this structural variant contributes to flexibility in the end product (not shown) in the xy direction. The second variant (b) from the left shows a continuous design of the long guide portion 1.1 which also ensures excellent leadership during assembly. After the third representation (c) and the fourth representation (d) from the left, the elongate guide region 1.1 was provided with recesses / openings (not designated) in order to save weight. In addition, the variants of representations (c) and (d) lead to FIG. 8 when installed also to a desired flexibility.
From the representations of FIG. 8 It can be seen that each guide region 1.1 has a first shoulder 1.2 in the press-in direction (z-direction) and a second shoulder 1.3 at its opposite end.

For variants (a), (c), (d) in FIG. 8 Thus, the elongated and provided with outer constrictions or recesses guide portion 1.1, which has a cross-sectional weakening between the first shoulder 1.2 and the second shoulder 1.3, used for two functions. On the one hand, this region ensures in the z-direction the transmission of the required press-in force in the production of the connection with the printed circuit board not shown here, and on the other hand it contributes to a flexibility in the end product in the x-direction and in the y-direction, which is advantageous in the event of vibrations and Shakes is.
The variant according to FIG. 8 , Representation (b) has a high rigidity in the z direction (press-in). Due to the fact that the guide region 1.1 is designed "over the entire surface" and thus has no reduction in cross-section, there is a very limited flexibility in the end product.

With the novel design, in particular with the use of the "double shoulder" in the form of the two shoulder elements 3, 5 between which a constriction in the form of the intermediate piece 4 extends (s. Fig. 1 ) allows a chaining of the press-fit contacts in the manufacturing process, without the cutting burr having a negative influence on the guide surfaces after the separation of the contacts.

According to FIG. 9 For example, the contours punched from the strip 10 or otherwise produced (laser, water jet cutting, etc.) of the press-fit contacts, for example from a roll 11 (FIG. Fig. 9 ) are fed to a separation station and there according to FIG. 10 at the intended separation points T from the belt 10 to individual press-fit contacts 1 according to FIG. 11 be separated. In this case, located in the direction of the press-in zone 2, the separation points T between each of the shoulder elements 3, 5, so that thus the intermediate piece 4 is formed and the guide surface 3.1 and 5.1 have no cutting ridge, whereby a good leadership is guaranteed in the press tool.
The thus isolated press-fit contacts 1 are now bent in an S shape and in each case two press-fit contacts 1 are connected to a component B ( Fig. 1 ), which is provided for contacting with a printed circuit board.

In addition to the production of press-fit contacts with guide areas whose axial guide length a1 is greater than their maximum width b1, as shown in the embodiments described above, it is also possible that the guide length and width are substantially equal or that the guide length is insignificantly smaller than the width of the guide area, while still a good guide is guaranteed, and that this guide area can be provided with a reduction in cross-section, which ensures flexibility in the x / y direction and guarantees stability in the z-direction for transmitting the press-in force.

The press-fit tool according to the invention used for pressing in the press-fit contacts is inexpensive and easy to manufacture. There is no drive required and thus allows the economical use of these press tools on non-stationary facilities.
It shows smaller dimensions than the known mounting combs with sliding part, whereby the components can be moved closer to the joint axes. The entire assembly can be reduced in size and weight.
