Description

The invention relates to an electronic device with Mehrkontaktstecker and a method for producing the same. The electronic device has a horizontally arranged circuit board. The printed circuit board is electrically connected via angled contact elements with the multi-contact plug. A housing, which surrounds the printed circuit board and the multi-contact plug, has a plug wall, on which the multi-contact plug is arranged with a plug collar surrounding the multi-component plug.

A widely used control unit concept, as it is known from the publication DE 39 06 973 C2 for the automotive electronics, has a housing box in which the circuit board is arranged horizontally. In this concept, an integrated molded connector interface is arranged on a connector wall of the housing box to the plastic housing box. In this housing box, a populated printed circuit board is mounted and contacted via a cover opening. The attachment and contacting is carried out by means of a soldering or pressfit process. The closing and sealing of the housing box via a housing cover, which is connected by potting or Reibschweißprozess with the housing box after PCB assembly media-tight.

An example of such an electronic device 3 in the prior art is in 13 shown in a schematic perspective and exploded view. A major component of this device is the complex plastic housing box 31 with the overmolded and integrated connector interface 33 , This is done with a contact elements 6 pre-equipped contact carrier 26 in a subsequent injection molding process to the in 13 molded homogeneous one-piece housing box molded. The prefabrication of such a contact carrier 26 is required to the partially rectangular bent contact elements during the overmolding to fix the connector interface 33 on the connector wall 8th the housing box 31 sure.

A fixation of rectangularly bent individual contact elements without such a prefabricated contact carrier 26 can technically be carried out with great difficulty. The encapsulation of the contact carrier in the housing box 31 However, this represents a very complex and therefore cost-intensive process. For positionally accurate positioning and for holding the contact carrier 26 During the injection molding process, special tooling technologies are required. Only selected specialist companies can perform such a conversion and encapsulation.

Mass production can not be carried out cost-effectively with such a control unit concept. On the one hand, a direct placement of the box housing with contacts is disadvantageously not possible because the box-shaped contour of the housing outer walls do not allow access to the inside connector area. The pressures and temperatures prevailing during the injection molding process can lead to displacements, warping and bending of the contact carrier 26 come, whereby the required position tolerances of the contacts can not be reliably maintained. In addition, the production of a housing box caused 31 with integrated molded or molded connector interface 33 Specialized companies charge high costs for tools, investments and individual parts and increase the dependence of manufacturers and users of such electronic devices on these specialist companies.

The object of the invention is to provide an electronic device with Mehrkontaktstecker and a method of manufacturing the same, with the dependence of special companies is reduced, the contact and assembly of the electronic device is simplified and cheapened.

This object is achieved with the subject of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims.

According to the invention, an electronic device with multi-contact plug and a method for producing the same is provided. The electronic device has a horizontally arranged circuit board. The printed circuit board is electrically connected via angled contact elements with the multi-contact plug. A housing, which surrounds the circuit board and the multi-contact plug, has a connector wall, on which the multi-contact plug is arranged with a plug collar surrounding the multi-contact plug.

The plug collar is without multi-contact plug an integral part of the housing and a contact carrier with angled contact elements forms the Mehrkontaktstecker, wherein an outer contour of the contact carrier of the inner contour of the Steckerkragens is at least partially adapted. Such an electronic device has the advantage that the complex encapsulation process for attaching the contact carrier as an integrated overmolded connector interface in terms of material, manufacturing and handling completely eliminated.

At the same time, the housing weight and also the tool costs are reduced. The housing may be considered and manufactured as a standard injection molding component. complex Tools and special technologies are completely eliminated. The usual added value of special suppliers is reduced and the scope of supply for suppliers with low costs can be switched to mass production. By eliminating the principle of an integrated overmolded connector interface and the replacement by a bipartition of the connector system, simple standard components that can be manufactured very favorably with standard suppliers and supplied by them. Both the manufacture and assembly of such electronic devices can be accomplished with simple standardized and robust processes.

In a preferred embodiment of the invention, the housing has a housing box with a lid opening and a housing bottom, as well as housing side walls and a housing rear wall opposite the connector wall. The Deckeloffnung can be closed media-tight as before with the help of a housing cover. For this purpose, the size of the lid opening corresponds to a printed circuit board size, wherein the printed circuit board can be mounted via the lid opening and can be electrically connected to inner contact ends of the angled contact elements.

In principle, the known housing box is maintained in this electronic control unit concept, to which a plug collar is already integrated with an injection molding step completed. Only before the attachment of the circuit board with its outer contour at least partially adapted to the inner contour of the Steckerkragens the housing box contact carrier with the contact elements from above through the lid opening in the housing box and then moved into the plug collar from the inside out, so that the inside Contact element ends can be connected to the circuit board, for example by a Pressfit process when attaching the circuit board.

In this assembly of the electronic device due to the division between multiple contact plug and surrounding plug collar is still no tightness against media given, however, the seal of the connector interior can be ensured by mounting a mating connector by default. This mating connector has sealing elements, which ensures a media-tight bond between mating connector and electronic device with the contact plug with the inner contour of the connector collar. Thus, the parting planes in the connector interior of the multi-pin connector to the connector collar are automatically sealed by the assembled mating connector.

In a further embodiment of the invention, the connector wall and the housing floor with partial regions of the side walls form a one-piece housing lower part and the rear wall and the housing cover with partial areas of the side walls form an integral housing upper part. With this preferred solution, the concept of the housing box is left, since now the rear wall is integrated into the one-piece housing upper part. This makes it possible to insert and fix the plug collar of the housing base on a prefabricated insert made of printed circuit board and contact carrier. Also, the contact wearer can form a replaceable insert in the plug collar, on which the printed circuit board is subsequently fixed after the contact carrier has been mounted.

In a further preferred embodiment of the invention, the plug wall with plug collar in the plug collar on a plug contact Halteeinssatz with slot-like Führungsoffnungen, wherein the Fuhrungsöffnungen are adapted in contour and dimensions of the contact elements. Such an embodiment has the advantage that it is possible to dispense with the separate production of a contact carrier with overmolded contact elements and instead a lower housing part is produced in a single injection molding process which already has guide openings for laterally insertable angled or bendable contact elements within the connector collar.

In an alternative, the contact carrier may be preassembled on the printed circuit board, and the printed circuit board and contact carrier may provide a replaceable compact insert for the lower housing part. Since the rear wall now belongs to the upper housing part, this insert can be inserted from the rear wall side into the plug collar of the housing lower part, before the upper housing part is connected via the connecting joint to the lower housing part in a material-locking, positive or non-positive manner.

The electronic device is preferably a vehicle-type device and may include an electronic parking brake (EPB) device, electronic guidance device, engine control device, transmission control device, anti-lock brake device (ABS) or electronic stability control device (ESP).

The control device concept and the various possible embodiments of the housing also include different methods for producing such an electronic device. These methods differ in individual process steps or in the sequence of the process steps, which leads to independent claims.

With a first method, an electronic device is to be mounted in a housing box, the method having the following method steps. First, a housing box of a connector wall, side walls and a rear wall, which is arranged opposite the connector wall, made. In this case, a plug collar is molded out of the connector wall outstanding. Furthermore, a housing cover is made, which will cover the housing box media-tight. Finally, a printed circuit board is bestuckt with appropriate components and a contact carrier made with angled contact elements. This angling is required because the printed circuit board is arranged horizontally in the housing box and outer contact element ends are to be arranged horizontally in the plug collar.

In a next step, the contact carrier is inserted in the plug collar such that the bendable or angled contact elements are aligned with their inner contact ends in the direction of the housing cover. Thereafter, the printed circuit board can be applied to support elements of the housing lower part and to the inner contact ends of the contact elements, wherein the inner contact ends are connected to the printed circuit board, for example by pressing the ends into contact openings of the printed circuit board with a press fit process or by soldering the inner contact ends. Finally, the housing cover is applied to the housing box while closing the lid opening of the housing. Despite the closing of the housing box, an unsealed fit of the contact carrier with the inner contour of the plug collar remains in the plug collar. However, this non-media-tight fit is automatically sealed media-tight when attaching a mating connector.

In a second variant of the method, the following method steps are carried out to produce an electronic device with a multi-contact plug in a housing which is equipped with a lower housing part plus plug wall and an upper housing part plus rear wall. First, a lower housing part of a connector wall and portions of side walls, which are integrally connected to a housing bottom made. In this case, a plug collar, which protrudes from the connector wall, formed on the lower housing part with the same injection molding process. Furthermore, a Gehauseoberteil is produced, which has a rear wall and portions of side walls, which are integrally connected to a housing cover.

In addition, a printed circuit board is equipped with components. A contact carrier is manufactured in which angled contact elements are fixed in such a way that angled towards one side inner contact ends and outer contact ends protrude to the opposite side. In this case, the outer contour of the contact carrier is at least partially adapted to the inner contour of the Steckerkragens. As a next step, the circuit board is connected to the contact carrier to a kit. This kit is then introduced with the contact carrier in the plug collar of the connector wall while fixing the circuit board of the kit on support elements of the housing base. Finally, the upper housing part can be applied to the lower housing part and sealed along the connecting joint.

In a further variant of the method, the prefabrication of a contact carrier is completely dispensed with. Accordingly, the manufacturing steps of the manufacturing method of a multi-contact electronic device change in a different order and manner. For this purpose, initially a housing lower part of a connector wall and portions of side walls, which are integrally connected to a housing floor, prepared. A plug collar, which protrudes from the connector wall, is formed at the same time. At the same time a plug contact holding insert is formed with slot-like guide openings in the plug collar.

Thus, in an injection molding process, all plastic parts and areas for both the lower housing part and the plug collar and for guiding and holding contact elements in slot-like guide openings of the connector wall are completed. Also in this case, a circuit board is initially populated. In addition, bendable or angled contact elements are made to match the slots provided in the plug-in holding insert guide openings. Thereafter, an introduction of the bendable or angled contact elements in the guide openings of the plug contact holding insert, which is an integral part of the connector wall, so that outer contact ends of the contact elements protrude from the plug contact holding insert and inner contact end of the contact elements are aligned in the angled state to the housing cover.

After completion of this housing base with inserted contact elements, the circuit board is connected to support elements of the housing base and with the inner contact ends of the contact elements, for example, by pressing the ends in contact openings of the circuit board in the form of a pressfit process or by soldering the inner contact ends to the circuit board. Finally, the housing of the electronic device can be closed by applying the upper housing part on the Gehauseunterteil.

This third process variant has the advantage over the preceding process variants that it is possible to dispense with the production of a complex contact carrier. For a higher effort in the introduction of the angled or bendable contact elements is then required.

In a further preferred embodiment of the invention, it is possible to pre-assemble the angled contact elements on the printed circuit board with their inner contact ends and to create a kit with the circuit board, which is applied to the PCB support elements while simultaneously pushing through the outer contact ends through the slot-like guide openings of the plug contact holding insert. For this method, a connector wall of the housing base is provided with slot-like chambers, which take over a guiding and holding function for the individual contacts to be populated.

In order to allow a direct loading of the contacts in the prepared chambers and guide slots in the plug portion of the housing, an access for the corresponding placement tools must be created in the housing. This is realized in that the rear wall opposite the connector wall is removed and forms an upper housing part with the housing cover so that sidewalls sloping downwards are created continuously from the connector area with a corresponding division of the side walls.

This results in an inclined connecting joint between the upper housing part and the lower housing part. Due to the resulting space now the individual contact elements can be fitted either in the already angled state directly in the lower housing part or the placement of the contacts in a straight state with subsequent bending of the rows of contacts in the direction of the upper housing part. The redesign of the housing walls results in an inclined, but even joining surface between the upper housing part and the lower housing part. The connection of the upper housing part and lower housing part can continue by means of z. B. linear friction welding can be realized. Likewise, the PCB assembly and contacting can be implemented as usual with the proven processes.

The invention will now be explained in more detail with reference to the accompanying figures.
