- the electrically isolated from the contact parts and part of a low voltage in particular 12 V, 24 V or 48 V. the electrical system of the motor vehicle
- the fuse circuit is to ensure that the contact parts of the connector are only then applied to the high voltage, if this completely contact.
- the fuse circuit is integrated into a control system for the high voltage source, the control system, the high voltage source is activated only when the backup circuit is closed due to a contacting of the contact elements of the connector.
- the connectors are designed such that when plugging the connector first contact the contact parts connected to the high current lines and then only the contact elements for the backup circuit. When releasing the contact elements of the backup circuit are first solved, whereby - if not already done - a Hochnapssbeaufschlagung the high current lines is interrupted. Only then are the contact parts connected to the high current lines out of contact.
- a corresponding connector is known for example from DE 20 2011 107 900 U1.
- the contact parts are designed as simple contact pins and contact sockets, which are plugged into each other when mating the connector.
- Such an embodiment of the contact elements of the fuse circuit requires a mating of the connector in an exact alignment with each other, whereby the handling is difficult.
- the present invention seeks to improve a particular intended for high voltage applications in or for motor vehicles connector.
- the connector should be characterized by easy handling when mating, secure contact and / or low manufacturing costs.
- This object is achieved by a connector according to the independent claim 1.
- Advantageous embodiments thereof are the subject of the dependent claims and will become apparent from the following description of the invention.
- a plug connection with (at least) one (at least) a first contact part having the first connector and a (at least) a second contact part having second connector, wherein the associated first and second contact parts in the assembled state of the connector spring-loaded contact axially, according to the invention is characterized in that the first contact part, at least in that section in which it contacts the second contact part, has a three-dimensionally curved end face and the second contact part at least in that section in which it contacts the first contact part, a conically widening (in the direction of the associated end of the contact part) Has depression in its end face, so that there is an annular contact area between the contact parts.
- conical is understood to mean a surface of revolution which is formed by a curve rotating about an axis, the conical recess preferably being trumpet-shaped, ie having a curved surface extending in the direction of the axis
- Recesses for example cone-shaped or partially cone-shaped and vase-shaped (ie with a curvature of the curve or the lateral surface facing away from the axis) are also possible ,
- the particular embodiment of the end faces of the first and second contact part ensures a self-centering of the contact parts with respect to their longitudinal axes.
- the first and / or second contact part at least in the area of the end face serving as a contact surface, has a radial mobility which can be realized, for example, by a corresponding mounting in a housing of the associated connector.
- the radial mobility can also be achieved by pivoting about an axis perpendicular to the longitudinal axis of the corresponding contact part.
- a further advantage of the plug connection according to the invention can result from the fact that no filigree components are provided in the contact area are. At least from the point of view of component protection, therefore, it may be possible to dispense with an interlock fuse circuit and design the plug-in connection in the case of the preferably provided high-current applications as so-called hot-pluggable.
- the end face of the first contact part can be part-spherical (that is, part-spherical).
- Such a configuration of the end face of the first contact part in particular in conjunction with a likewise preferred trumpet-shaped configuration of the recess of the second contact part, can be characterized by a good Aerozentri mecanicsfunktion gleich and a particularly good insensitivity to Brockkoaxiali decisiv or non-parallelism of the longitudinal axes of the contact parts.
- each of the plug connectors has a housing receiving the associated contact part.
- at least one of the contact parts is spring-loaded axially displaceably mounted in the associated housing.
- This can represent a structurally simple realization of the axial spring load of the contact area formed between the contact parts.
- the spring load of the contact region can then be realized preferably by means of a coil spring surrounding the axially displaceable contact part, which is supported between a section, for example an outer circumferential collar of the contact part and a section, for example an inner circumferential collar of the housing.
- the spring load can thus be used on a cost as an additional purchased component, wherein the contact part surrounding the arrangement of the coil spring is also characterized by a small footprint.
- FIG. 1 shows a first embodiment of a connector according to the invention in a perspective view
- FIG. 2 shows a first connector of the plug connection according to FIG. 1 in a perspective view
- FIG. 3 shows the connector according to FIG. 2 in a longitudinal section
- FIG. 4 shows the second connector of the connector according to FIG. 1 in a perspective view
- FIG. 5 shows the connector according to FIG. 4 in a longitudinal section
- FIG. 6 shows a second embodiment of a connector according to the invention in a perspective view
- FIG. 7 shows a first plug connector of the plug connection according to FIG. 6 in a perspective longitudinal section
- Fig. 8 the second connector of the connector according to FIG. 6 in a perspective longitudinal section.
- the connector shown in Fig. 1 comprises a first connector 1 (see Fig. 2 and 3) and a second connector 2 (see Fig .. 4 and 5).
- Both connectors 1, 2 each comprise a housing 3 and a contact part 4, 5 arranged at least partially in the respective housing.
- Both contact parts 4, 5 have a plug-side end which is provided for axial contact with the respective other contact part 4, 5.
- the two contact parts 4, 5, a cable-side end, which is provided in each case for connection to a conductor 6 of a cable, not shown, moreover.

- a mechanical connection between the contact parts 4, 5 and the conductors 6 can be done for example by soldering, including soldering holes in the contact parts 4, 5 are provided.
- the contact part 4 of the first connector 1 has on the plug side a part-spherical end face 7. This contacts an end face of the contact part 5 of the second connector 2 in a recess 8, which is formed in a trumpet shape (in the direction of the plug-side end) widening. This results in an annular contact area between the contact parts 4, 5, which is also given when the two connectors 1, 2 or the two contact parts 4, 5 not exactly coaxial (with respect to the longitudinal axes of the circular cross-sections having contact parts 4, 5) aligned with each other.
- the connector is relatively insensitive in terms of contact reliability with respect to positional and form tolerances of the components.
- the contact part 4 of the first connector 1 is axially (ie in the directions defined by the longitudinal axis) movably mounted within the associated housing 3 and biased by a biased coil spring 9 in the direction of the second connector 2 ,
