Definitions
- the present invention relates to a plug-in device for motor vehicles for making a variety of electrical contacts when connecting to a suitable mating device with a large number of contact devices, each with corresponding contact devices of the mating connector can be connected in a plug-in direction, the contact devices one or more ESD contact devices (electrostatic discharge) for connection to electrostatic discharges sensitive components include.
- Control units often have electronic assemblies that face each other electrostatic discharges are sensitive.
- Electrostatic discharges occur, for example, when installing control units or during their maintenance work, if the fitter does so Touched plug contacts. Because of these electrostatic discharges can lead to damage or destruction of assemblies. To avoid this, use suitable diodes respectively Capacitors connected in front of the modules at risk. The problem however, here is that when interconnecting multiple modules with ESD protection so large protective capacities can arise that it too significant signal deformation comes. Such signal deformations are but only tolerable to a certain extent, which is why modules with ESD protection can only be interconnected to a limited extent.
- the published patent application DE 39 09 912 A1 a multi-pin connector known to connect one to controlling aggregates of a wiring harness connected to a motor vehicle serves with an electrical switching device in motor vehicles.
- the connector the plug device is provided with a short-circuit bridge, arranged on the contact carrier with simple means to save space and costs is.
- the short-circuit bridge prevents the connector from being removed by short-circuiting associated contact parts, that by connecting of current-carrying devices, for example test devices or by touch or tools of a fitter contact pairs through electrostatic Charging aggregates connected to the wiring harness in undesirable Way can be driven.
- the specially designed short circuit bridge which is also a moving part, but is very complex and vulnerable.
- the object of the present invention is therefore in plug devices to ensure effective and simple ESD protection.
- a plug-in device for Motor vehicles for making a variety of electrical contacts when connecting with a suitable mating device with a variety of contact devices, each with corresponding contact devices the mating connector can be connected in one direction the contact devices are one or more ESD contact device (s) for connection with against electrostatic discharges sensitive components include and where the one or the multiple ESD contact device (s) or part of the multiple ESD contact device towards at least one of the other contact devices set back in the direction of insertion or perpendicular to the direction of insertion is / are staggered.
- the invention can preferably be used, for example, in control units and harness connectors that have connector pins. It can be This is to prevent the bare ones that emerge from the outside Plug pins are touched unintentionally.
- the resetting of the contact devices according to the invention can also be realized in that the insensitive contacts or Pins as plug pins and the sensitive ones as plug sockets are executed. This also reduces the probability that the sensitive contacts are touched.
- Contact devices may be provided. So it can offer some benefits the sensitive contact devices mechanically by resetting and other non-resettable contact devices by electrical Protect protective components. It may also make sense to reset the or move ESD contact devices not only on the edge of the Plug device, but also to be arranged between other contact devices.
- FIG. 1 In the figure is a plan view of a multipole connector 1 and matching mating device 2 shown.
- the connector has a large number of contact devices, which are used as plug pins 3 are trained.
- the mating connector 2 has correspondingly arranged Sockets, which are not shown in the figure, so that Plug device 1 and the mating plug device 2 into one another in the plugging direction S are pluggable.
- the insertion direction is the same throughout the document defines that the mating connector is assumed to be fixed and the Plug device is moved towards the mating connector.
- the middle three contact devices 31 of the plug device 1 are opposite the other contact devices 3 reset in the direction of insertion. This obviously has the advantage that the three contact devices 31 face each other the contact devices 3 can be touched less easily. In the figure, this is indicated by spark discharges F, which are therefore only at exposed points on connector 1. Are preferred this outer casing edges or the protruding pins 3.
- the contact devices 31 of the plug device 1 can additionally offset up or down in the drawing plane depending on it be whether a possible touch is from above or from below becomes.
