Description

The invention relates to an arrangement according to claim 1.

In the prior art, various arrangements are known in which a carrier has an electrical contact and the electrical contact is electrically contacted via a contact pin. For this purpose, the carrier has a hole through which the contact pin is guided. The contact pin can be electrically conductively connected via a solder to the electrical contact of the carrier.

The object of the invention is to provide an improved arrangement with a carrier and an electrical contact.

This object is achieved by the arrangement according to claim 1.

Further advantageous embodiments of the invention are specified in the dependent claims.

An advantage of the invention is that greater flexibility in the arrangement of the contact pin and / or in the arrangement of the carrier is possible. This is achieved in that the hole is designed in the form of a slot, wherein the slot is guided to an edge of the carrier. The slot is open at the side and preferably the slot has the same depth as the hole. Due to the design of the slot, the contact pin can be aligned from different directions, in particular laterally with respect to the carrier in the direction of the contact.

In one embodiment of the arrangement, the contact pin is attached to a housing and the support is also secured to the housing. In this way, a stable mechanical arrangement is provided, so that a relative movement between the contact pin and the carrier is avoided. Thus, a load on the mechanical and electrical connection between the contact pin and the electrical contact of the carrier is largely avoided.

In a further embodiment, the contact pin is laterally led out of a side wall of the housing and guided laterally in the direction of the contact. Due to this arrangement, the carrier can be arranged in a housing which has a very small receiving space. This is achieved in that, for example, during assembly of the carrier, the contact pin, which protrudes from the side wall of the housing, is guided into or through the slot of the carrier. Thus, the carrier can be mounted in a housing, wherein the contact pin protrudes at least partially into the slot and thus over an edge region of the carrier. Thus, the inner size of the housing can be made smaller despite the contact pin. This saves material and installation space for the housing.

Depending on the selected embodiment, the carrier may be arranged at the level of the contact pin. Thus, it is possible, for example, to arrange the carrier near a bottom surface of the housing. In a further embodiment, the carrier may be arranged between the region in which the contact pin protrudes from the side wall and the bottom. Thus, the height of the housing can be reduced.

In a further embodiment, the contact pin has an angled end piece, with the end piece projecting from the slot over a side face of the carrier, in particular in the direction of the housing bottom. By the angled end piece is a relatively long portion of the contact pin for electrically conductive connection with the electrical contact of the carrier, in particular with solder available. In this way, on the one hand, the mechanical connection between the contact pin and the carrier is increased. On the other hand, the electrical resistance of the contact connection between the contact pin and the electrical contact of the carrier is reduced due to the relatively large area of the contact pin, which is electrically connected to the electrical contact.

In a further embodiment, an electrically conductive layer is formed on a side surface of the carrier adjacent to an edge region of the slot, which is electrically conductively connected to the contact pin via an electrically conductive material, in particular solder. The arrangement of the electrically conductive layer, which may be arranged in particular U-shaped adjacent to the slot, the electrical conductivity between the contact pin and the electrical contact of the carrier is improved.

In a further embodiment, the housing has a connection region with at least one further electrical contact pin, in particular for connecting an electrical connector. The further contact pin is electrically conductively connected to the contact pin, wherein in particular the contact pin and the further contact pin are integrally formed. In particular, the contact pin and the further contact pin can be connected to one another via an angled section.

Due to the one-piece design of the contact pin and the further contact pin, the structure of the arrangement is simple and inexpensive, wherein in particular the angled portion causes an increased mechanical attachment in the housing. The housing may be made of plastic, for example.

In a further embodiment, the carrier has an electrical circuit, in particular a sensor, wherein the circuit is electrically conductively connected to the contact. For example, the sensor may be formed as a Hall sensor.

In a further embodiment, the electrical circuit is arranged on a side surface of the carrier, which faces a housing bottom. In this way, a secure cover of the electrical circuit is given by the housing and the carrier.
