Definitions
- the present invention relates to a sensor module.
- the present invention relates to a sensor module for mounting on a circuit board.
- An electrical control unit includes a circuit board with conductor tracks. Electrical components are attached to the circuit board and electrically connected to the conductor tracks. Many components can be inexpensively surface mounted to the board (surface mounted devices, SMD), others require through hole mounting (through hole technology, THT). Larger components, such as certain sensors, can first be attached to a support structure, which is then mounted on the circuit board. Electrical contacts of such a sensor can be connected to a conductor track directly or by means of an electrical connecting element.
- the sensor can be sensitive to electrostatic discharge (ESD) that can occur during assembly or operation.
- ESD electrostatic discharge
- the static electricity can flow through the sensor and damage or destroy it.
- the sensor If the sensor is required to control a safety-related function, it should be secured against damage from such a discharge. If the sensor has an electrically conductive housing, this can be connected directly or via a resistor to an electrical ground, a device ground or an earth potential in order to discharge an overvoltage.
- the housing cannot have a dedicated contact point, so that its electrical contacting can be complex. It has been proposed to use a telescopic, spring-loaded contact known as a pogo pin for this purpose. Such a contact is usually soldered to the circuit board at one end, so that the positioning of the sensor with respect to the circuit board is determined by the dimensions of the pogo pin. In addition, the soldering point on the circuit board can be permanently damaged under mechanical stress from the sensor. The pogo pin also incurs costs. It is an object of the present invention to provide an improved sensor module that assists in dissipating electrical charges from a sensor. The invention solves this problem by means of the subject matter of the independent claims. Subclaims reflect preferred embodiments.
- a sensor module for attachment to a circuit board comprises a support structure for mechanical attachment to the circuit board; a sensor for providing an electrical signal; and a first contact element attached to the support structure.

- the first contact element is elastic in the area of the recess. In the area of its second end, the first contact element can protrude from the support structure, so that it can be deflected by the sensor with respect to the support structure. An elasticity of the first contact element in this area can be determined by its material and its shape.
- the elasticity can ensure that the first contact element bears against the conductive housing of the sensor with a predetermined force and thus ensures reliable electrical contact.
- a shape of the first contact element at its second end can be selected in such a way that threading or inserting the sensor into the recess is not impeded.
