Electronic module with inserted electrical contact

Field of the invention

The invention relates to an electronic module that can be used for example in a vehicle, such as a car, truck, bus or motorcycle.

Background of the invention

An electronics module usually comprises a housing which carries one or more printed circuit boards with electronic components and which additionally provides a plug, via which the electronic module can be electrically connected to other components. For contacting, for example, angled lead frames can be used, which are injected into the housing.

For the production of the electronic module, the angled lead frames are individually inserted into a tool and then encapsulated with the housing. The

Contacting the stamped grid in the housing with the circuit board then takes place for example via soldering or ramming.

Summary of the invention

It is an object of the invention to provide a contact for an electronic module, in which the items and the contact can be made inexpensively.

This object is solved by the subject matter of the independent claim. Further embodiments of the invention will become apparent from the dependent claims and from the following description. The invention relates to an electronic module, by which a mechanically coherent assembly can be understood, comprising a housing and electronics housed therein. For example, that can

Electronic module designed to determine an angular position of a throttle. The throttle may be the throttle of a two-wheeler (or

Motorcycle). In other words, the electronic module may be an angle sensor. According to one embodiment of the invention, the electronic module comprises: a

Printed circuit board, which carries at least one electronic component, at least one Kontaktierungsstift (or Kontaktierungsnagel), which is electrically and mechanically connected to the circuit board, at least one male tongue, which is electrically and mechanically connected to the Kontaktierungsstift, and a housing, the electronics receptacle for the PCB provides and the one

Plug receptacle for the at least one connector tongue provides. In other words, a printed circuit board is accommodated in the housing, which is electrically connected to the connector tongue via a contacting pin. The at least one connector tongue is inserted into the connector receptacle and the at least one contacting pin is inserted through the electronics receptacle into the connector tongue. When mounting the electronic module is the

Inserted plug in the plug receptacle (and not encapsulated with the housing). Subsequently, the contacting pin is inserted through the receptacle for the circuit board in the connector tongue, whereby the connector tongue is fixed in the housing. The housing can thus be injected without inserts, so it can be a pure plastic part without injection. This can reduce the cost of the housing.

It is understood that the electronic module will usually have several Stecke, in turn, via several Kontaktierungsstifte with the

Printed circuit board are connected.

According to one embodiment of the invention, the printed circuit board on the

Contact pin inserted. After the connector tongue is integrated in the housing, the contact pin is inserted into the connector tongue via the electronics receptacle rammed or stuck in this. After the Kontaktierungsstift is mounted in the connector tongue, the circuit board can be pressed onto the contact pin / rammed. According to one embodiment of the invention, the at least one

Connector tongue at least two openings for insertion of a

Contact pin on. A connector tongue usually has a hole in which in a further step of the contacting pin

can be rammed / pressed. If several identically executed plug tongues are used in an electronic module, each of the

Plug tongues have two or more holes, so that the corresponding Kontaktierungsstifte can be plugged into different holes (at different heights), and yet the same type of connector tongue can be used.

According to one embodiment of the invention, the at least one

Connector tongue on a profile that is designed to jam in the connector receptacle, so when plugging the connector tongue does not accidentally dissolves. For example, the connector tongue may have lateral barbs that can engage, for example, in an undercut in the connector receptacle.

According to one embodiment of the invention, the at least one

Plug tongue designed as a flat component. For example, the connector tongue may have a substantially cuboid base body and / or be punched out of a metal sheet.

According to one embodiment of the invention, the electronic module further comprises a plurality of plug tongues, wherein the plug tongues are made identical. The plug tongues can be the same parts, which can reduce the cost of their production. For example, two, three or more connector tabs may be aligned side by side in the connector receptacle.

According to one embodiment of the invention, the electronics receptacle and the plug receptacle in the housing are substantially orthogonal away from each other. The two recordings are connected together in the housing, wherein at the

Production of the electronic module in the connector receptacle the at least one Plug tongue and substantially orthogonal to the electronics receptacle of at least one contact pin is inserted.

This advantageously a particularly simple and safe installation is achieved. Because of the orthogonal arrangement can be in a simple manner, e.g. optically, before inserting the at least one Kontaktierungsstiftes check whether the at least one corresponding connector tongue is inserted into the connector receptacle and is plugged into the correct position in which the Kontaktierungsstift can be inserted into the connector tongue.

Further advantageous can be by the orthogonal orientation of

Plug receptacle and electronics recording and the consequent

Orthogonal mounting of at least one Kontaktierungsstifts in the at least one connector tongue particularly well meter the joining force and control the manufacturing process, creating a particularly reliable and

production-safe connection between the at least one contacting pin and the at least one connector tongue can be formed. In addition, can be due to the orthogonal arrangement significantly space along the axis of the

Save longitudinal extension of at least one connector tongue. This can be very important in applications in the automotive sector with limited space.

The contact pins or the pins can be made solid or spring-loaded. For example, one end or both ends of a contact pin can be designed such that it can be resiliently compressed. Thus, a cost contact is possible.

According to one embodiment of the invention, at least three

Kontaktierungsstifte arranged in the electronics receptacle, for example in a triangle to each other. The Kontaktierungsstifte may be distributed on the surface of the circuit board. In this way, the circuit board through the

Contact pins are supported.

According to one embodiment of the invention, the electronic module further comprises a pen holder which engages around at least two contacting pins and fixes the contacting pins relative to each other. The Kontaktierungsstifte can be shot individually or on a prefabricated group part (the pen holder) to be assembled. The pen holder can simultaneously serve as tolerance compensation and insulation between Kontaktierungsstifte and PCB.

According to one embodiment of the invention, the Kontaktierungsstifte are encapsulated with the pen holder. The Kontaktierungsstifte can before mounting in

Housing be injected in a plastic. But it is also possible that the Kontaktierungsstifte be injected later in the pen holder.

According to one embodiment of the invention, the housing is manufactured without the at least one connector tongue and without the contacting pin

(injection-molded, for example). Subsequently, the connector tongue and the contact pin are subsequently inserted into the housing. The housing is made without the contact parts. The connector tongue and the contact pin can be retrofitted.
