According to the invention, the object is also achieved, in particular, by a radar sensor for a vehicle, which has an instrument plug.
A particular advantage of the invention is that, by providing the means, an air exchange between the instrument plug and the outside air can be achieved in a simple manner via the ventilation channel and, at the same time, an improved prevention of water from entering the instrument plug can be achieved.
Preferably, the ventilation channel is a ventilation channel and/or an exhaust channel. Preferably, the ventilation channel extends in a ventilation housing of the instrument plug. Preferably, the housing with the ventilation housing is designed as an injection molded part. Preferably, the ventilation channel is configured as a bore in the housing.
Preferably, the instrument plug has a circuit board. Preferably, a component holder is provided between the housing and the circuit board. Preferably, the circuit board can be fixed to the component holder by means of a fixing device.
Preferably, the circuit board (printed circuit board (Leiterkarte), printed circuit board (Platine), printed circuit board (getdruckte Schaltung) or PCB) is a carrier for electronic components. The circuit board is used for mechanical fixation and electrical connection.
Preferably, the circuit board is made of an electrically insulating material together with electrically conductive connections (conductor circuits) attached thereto. Fiber reinforced plastics are generally preferred as the insulating material. The conductor circuit is preferably etched by a thin layer of copper. The structural elements are soldered on the soldering surfaces (pads) or in the solder eyes. The structural elements are thus simultaneously mechanically held and electrically connected at these imprints (footprints). Preferably, the larger member is also secured to the circuit board using a cable connector, adhesive or screws.
According to one embodiment of the invention, the housing is formed integrally with the ventilation housing or the ventilation housing can be connected to the housing as a separate component.
Manufacturing costs can be minimized by providing the one-piece member. Preferably, the separate component is connected to the housing by means of screwing. Preferably, the separate member has threads and the housing has mating threads.
According to one embodiment of the invention, the welding surface for the membrane is arranged at the end of the ventilation channel in the instrument plug or the welding surface for the membrane is arranged on a separate component.
In this way, the membrane can be mounted in a simple manner on one end of the ventilation channel or on a separate component. The diaphragm can be arranged to block liquid.
Preferably, the welding surface is provided on one end of the separate component.
According to one embodiment of the invention, the ventilation housing has at least one recess on the end face at the first end.
By providing the recess, air exchange between the instrument plug and the outside air takes place via the ventilation channel.
According to one embodiment of the invention, the component forms a contact surface with the end face and at least partially covers the recess.
In this way, an air exchange can be achieved via the ventilation channel, wherein an additional protection against water entering the instrument plug can be achieved.
According to one embodiment of the invention, the transition from the recess to the inner circumferential surface of the ventilation housing is at least partially rounded.
This embodiment allows a simple air exchange, wherein an improved protection against water entering the instrument plug is achieved.
According to one embodiment of the invention, a free space is formed between the component and the inner circumferential surface.
Thus, an air exchange between the instrument plug and the outside air can be achieved via the ventilation channel.
According to one embodiment of the invention, the component is a screw.
Alternatively, clamping means, bolts (Spint), mandrels or other means that can be introduced into the ventilation housing are provided.
According to one embodiment of the invention, the ventilation housing has an internal thread for receiving the screw.
The screw can thus be fixed in the ventilation housing in a simple manner.
Preferably, the radar sensor is configured as a lane-change assistant based on a 24-GHz radar sensing device. Preferably the radar sensor is arranged to continuously view the space in the rearward direction and to warn the driver when a vehicle approaching behind an adjacent lane is performing a passing operation or a lane change operation. During a lane change, particularly due to so-called blind spots, there is an increased risk of accidents, and the lane change assistant notices the "blind spot" and warns the driver of the dangerous lane change. Preferably, the sensor of the lane-change assistant is arranged to detect, for example, a passing motorcycle driver quickly, to avoid accidents.
Preferably, the radar sensor is designed as a "range alarm" based on a 24 GHz radar sensor system, which warns the driver when a permissible safety distance is undershot, but does not intervene autonomously in the drive train. Preferably, the radar sensor is designed as a three-function camera for recognition of driving routes and traffic signs and for simulating the function of an adaptive/glare-free high beam. In lane keeping assistance, once the driver approaches a lane marking, the vehicle is moved back to the lane center.
